I noticed that 1 hour of display on at normal brightness (just that, no aps running, no-nothing) drains my battery of about 20%, with the default wallpaper. I'm pretty "impressed" by this, and I wonder... is it normal?
In addition, I had a feeling that was more than confirmed by a specific test that I performed. Well oddly enough to say....
With display brightness set to minimum, and just the diplay on continuously for 20 mins, I get 10% battery drain, but...
With display brightness set to 60%, and again just the diplay on continuously for 20 mins, I get only 5%, and the units' temperature also lowers a bit!!!
I also get similar results (5% drain or so) with display brightness set to 80%...
Therefore, at least for my unit, it looks like for saving battery life, I should keep the display brightness fix at 60% or even more!
I don't know why this happens but I suspect that the brightness regulator of the display drains much more power than the amount it helps to save from dimming the display!
Anyone to confirm?

Not to be rude, but there are a few threads concerning power consumption/battery use/display . if you have a browse around, and did some reading up, you would find some of the solutions that other people are using?
also, when posting a thread like this, you should try and give as much pertinent information as possible, for example, what firmware are you running? have you rooted the phone? is it branded or unbranded?
Again, not being rude to you. Just trying to give you some pointers.

Hi Stoney,
thank you but yes, actually I did make some search, but couldn't find anyone claiming that his dislay is draining more at dim than at full brightness... Maybe I was not searching in the right direction, in such case I would be pleased if you could give me some hints.
Cocerning my phone, it's unbranded and unrooted. I bought it 5 days ago, and I've updated it with Kies to the latest firmware available from Samsung:
Build is Gingerbread XWKE7
Kernel is 2.6.35.7-I9100XWKE7-CL215725
Baseband is I9100XWKE1
Did not notice any improvement, nor any degradation, in battery life after updating.
At the moment my battery is at 77%, and display is reported to have drained 68% of it, and it's reported to having been on for 1 h 15 mins.
This means that the display alone has drained 68% of 33% battery drain in 1 h 15 min, which makes approx. .68*33=22.5% of battery drain in 75 mins.
It means that, the display alone, without CPU or watever, totally drains my battery in 75*100/22.5=330 mins, or if you prefer, in 5 h 35 mins.
Well, I find this value really frustrating since aside from being miles away from my old nokia N95 8GB, I'm wondering how people can say that they get more than a full day of heavy usage out of this phone... I don't know if battery life is better or worse than other touch screen phones, because that's the first one I own, but I remember having read that Iphone 4 for instance, survives for more than 7 hours with continuous web browsing (and hence not only with the display on, but also with many other tasks running)...

I can imagine it is quite frustrating, seeing people post that their phone is lasting a full day+(mine does) and yours isnt.
So what steps have you taken?
before updating to KE7, did you (backup your apps/anything on internal memory you want to save) and then wipe the cache, and factory reset(from the privacy settings on the phone)?
Do you use the samsung hubs/'AP app,etc? If not, have you tried freezing/deleting them?(I froze mine on the basis of you never know when/if you want to use them at some point)
These are the two things I did immediately after updating to KE7 and finding out it was draining the battery, after I performed those two steps, things went back to normal for me.
I dont tend to hammer the phone(now anyway), but on an ave day, I spend around 30-45 mins chat, 15-30 texts, 30-45 mins gaming, 2 email on push sync, fb/twitter updates, xda app. I dont tend to watch video much on it(I have a tab for that, a very much underused tab since I got the S2).
I usually have 20-30% battery come bedtime. I have the display on auto, timeout on 2 mins.

You have to take two things into account:
1) Your N95 had a MUCH smaller display, with another screen technologie and fewer pixels, as well as a much slower chipset and no touchscreen.
2) The Iphone too has a smaller display, with backlighting, which drains less battery and has as well a less powerful SOC.
That a 4.3 inch display would drain the battery fast, shouldn't surprise anyone imo. Compared to the Iphone it's a ~20% difference in screensize. Since the displays drains most of the battery, it shouldn't surprise anyone that the Iphone lasts longer ...
Stoney, sorry but if you tell me to stop/freeze processes, you haven't understood my post. I repeat that the problem with my phone is the display that drains about 1Watt only for being on, no matter the brightness (actually, at high brignthess it drains LESS). This has nothing to do with processes. When the display of my phone is off, the battery lasts ages. For instance, this evening I went jogging for one hour with Sports Tracker (on GPS) and the music player always on, but the display off. The battery just dropped about 10%, which is perfectly normal. If instead I dare to turn on the display, I can actually see the battery draining and the phone becoming warm.
II would be useful if you could do a small check for me: after full charging the battery, leave the screen on for a while with about 50% brightness and the home screen. After 2 or 3 hours, could you please report to me the screen % usage, and the corresponding net "on" time? Only this can be a proof that my unit is faulty, and the display is draining much more power than normal.
Chalid, for sure this display is bigger than that of the iPhone and even bigger than that of the N95. But does this justify a cosumption of more than 1 W (since it drains the full 7Wh battery in just 5.5 hours)? Well, in my opinion, by no means! And besides, where the AMOLED displays said to require less power than LCDs, or were they not?
IMHO a display draining more than 1 W is a killer on any mobile phone! (again: UNLESS mine is faulty for some reason)

*cough* 100% - 77% = 23% = 15.64% in 75min is quite good to be honest.
480mins which is 8hours straight display on time....very good if u ask me.

1 hour 8mins with my display on today has used 17.98% of my total battery with brightness at auto
My screen eats also alot of the battary.
Like 4-5 hours and thats all and on minimum brightness.
I try to set it on 60 percent also and ofc autobrightness disabled.
Report later
is it true that the phone uses less battery when you select a brightness of 60%+ or auto? cause I use 15% all the time.
i have the same problem,never under 45%.

amoled screens were quoted to consumers as using less power. but the tests i've done, i contend that amoled uses far more power than the SLCD screens HTC is using for example. like significantly more. so the screen is a killer for sure on your device, dont get fooled.

Like Locster126 pointed out, it's only 15.64% for your 75 minutes of usage. The battery has 6,11Wh, which makes a power consumption of approx. 0,76W. But you must not forget, that the AMOLED display drain is highly dependent on the content you're displaying. Thats the difference to the LCD. While the LCDs backlight is mostly responsible for the drain, the AMOLEDs individual pixels drain the battery, which means that light-colored content drains more battery - more than on the LCD, while dark-colored content doesn't.
Nothing wrong with your screen.
EDIT: I will test the power consumption of the HD2s screen later ..

Just finished the testing. After loading the HTC HD2 to 100% in flight-mode, I unplugged it and let the screen continuously on at full brightness for 30 minutes. The battery went down to 92%. So 8% for half an hour. That means, the screens power consumption at full brightness is ~0,73W (battery capacity is 4,55Wh).
So definitely lower than your SAMOLED power consumption ... but so is the display quality ...

Oops! You're right!
Well ok, 8 hours so....
And considering that the battery has a capacity of 6.2Wh, the display actually drains 0.78W, at normal brightness (auto brightness was set to on and I was indoor, daytime).
In any case, that's not totally fair because it doesn't consider all the rest that's draining power from the battery. Considering my "normal" usage of the device, I get about 60% display ratio after a full battery discharge (to be optimistic).
This means that I have .6*8= 4.8 hours of "normal" usage to spread across the day.
I don't play 3D games and use WiFi just for syncing the emails and podcasts (10 minutes to say the most). I also don't use Bluetooth. I keep the GPS on all the time but turn on packet data strictly when necessary, and make just 5 minutes of calls and send 5 SMS... In substance, I use the device like a normal 150 euros phone.
This is my first touch screen device (as I said,I come from a Nokia N95 8GB), therefore I would like to understand if 4.8 hours continuous normal usage of the phone from fully charged to "mayday, shutting off!" can be considered normal.
I don't uderstand how some people can say they get one full day heavy usage on it, or 2 full days normal usage, playing 3D games, continuously syncing accounts, watching videos, surfing the internet, etc!!!!
My replies (thank you all) ->
to (•.•) (nice your nickname! ):
not far from mine. Tell me if you get some improvement at 60%. I will also repeat the test on mine, trying to be more systematic as possible, since I really want to be sure of what I have seen.
to seaweeduk:
please be more clear. Just the display or the entire unit? In any case that seems to be a much smaller consumption than that of my display...
to guigs91:
you mean you also noticed this odd behaviour?
to Mittaa:
right, but before setting brightness to a low level I want to be sure that it actually drains less power, and that's how I figured out that actually it's the other way around (I hope I made something wrong, as said I'll re-check better).
to RogerPodacter:
sadly, I perfectly agree with you.
to chalid:
thank you for reassuring me. To be honest however I'm not totally sure that black pictures drain significantly less power than white ones. I feel more that it's simply the bias current of the display, to drain a lot, and the rest is not so important. In fact, if you look at a 100% black picture totally in the dark, you'll see that it's not fully black. I's ALMOST fully black (much more than LCDs), but you can actually notice that the display is on (and therefore it is powered). If you shut off the display, you'll notice the diference.
to guigs91:
I also tried everything without success. Apart from noticing that perhaps high display brightness helps a little!
Did I forget someone? Ah yes, tommehh :
this is what I noticed. Let me re-check 'cause I find hard to believe myself!

That's absolutely okay in my opinion. But like I said: If you want 1 week usage off one charge, you need to get a phone with a smaller display, because all of those 3.5+ inch touchscreens drain the battery pretty fast.
Hi, this issue is specific to my NON-ROOTED Samsung Galaxy S2. I have seen other simsilar issues for other phones and they don't seem to help. My Battery doesn't seem to last more than a few hours. No more than 5-8 and it's dead. I turned off the Data and wi-fi. I set my Wallpaper to a Black background. It just sits on the desk and after a few hours it's almost dead...
What can I do to fix this?
Rooting is not an option at the moment.. I'm still reading and learning about it as I don't want to create a paperweight and/or void my warranty...
No offence mate but for a start you can search the forum and you will literally find dozens of threads on the very same subject which have been posted on here over the last few months.
Search and you'll find the answers your looking for, a tip freeze the Samsung bloatware in Titanium Backup and your battery life will improve substantially, there are many other methods to improve battery life you can find them yourself.
I get over a full day on heavy usage...
No offense taken, but most point to Rooting my phone...This is not an option for me at this time....I'll look some more, I guess...

I have unrooted phone and get around 17-20 hours heavy usage.
I would suggest you flash a 2.3.5 Rom via Odin as they seem to have better battery management if you haven't done so
http://forum.xda-developers.com/showthread.php?t=1075278
you dont need to be rooted to flash new roms via odin
Also advisable to charge battery till full then use till its like 1% then recharge full and so on to calibrate it a bit.
Rogue apps can eat your battery life as well so If you can afford it do a full wipe and reset if you can and see if it makes a difference.

You guys need to give more information if you really want decent assistance, there is an app called better battery stats, you want to look at your partial wakelocks section in that particular app, go get it either on this forum or in the Market, post screenshots of your battery graph in Settings>About Phone>Battery Usage and click on the time, also a screenshot of your partial wakelocks will reveal the issue 90% of the time
Also, there is no need to root your phone to achieve good battery life, unless it is found that a system app may be the cause of the poor battery which is hardly ever the case, anyone who points you to rooting to get good battery life has very limited knowledge of android and what is the cause of poor battery life...
Usually downloaded apps and user settings are the cause of poor battery, there is absolutely no need to root to be able to fix those problems.....
I noticed this one too...My stock DXI2 room tend to be a battery hogger and the display consumes around 60% of my entire battery life...
agreed I'm getting nigh on 2 days battery life nowadays maybe one and a half of moderate to high usage! certainly don't need to root and install a new ROM.

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.
Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......
You should definitely try better battery stats app. It helped me to identify the app that kept my phone awake continuosly. My battery life increased from 8-9 hrs to 15-17 hrs after uninstalling that app. I even bought the paid version from market after that. Must have app!!! Give it a shot. Its free for XDA users. But if it helps you then please do consider buying it to support the developer.
yup. My SGSII is on KJ3 stock & I get easily around 1 day & 16-17 hrs before i need a charge. This is with moderate to heavy usage (depends on your perspective) which includes:
1. Display is on roughly 1.5 to 2 hrs
2. Voice calls roughly 2-3 hrs
3. 100 odd texts
4. 30-40 mins of listening to music
5. 20-30 mins of browsing
6. 30 mins of running benchmarks

Charge your phone fully and use it as you would normally, the screenshots you provided doesn't show much, what you have to do is click on the very top where it says 22h 52m, that would take you to another shot that shows your "screen on" time in a linear graph just below "Awake" time, that's the screen that would tell us if you are having wakelocks.QUOTE]
Ok, I had the phone plugged in to the laptop to transfer my Memo's from my BB/Outlook over to the phone, so it only says it has been unplugged for 3 min..If you want longer, let me know, as I'll do another one tomorrow.
This one is from 49 min unplugged...
As far as that app. I'll download it now and run it for a day or two and see what happens...will post back soon!
Thanks for all your help people!!!

.Secondly, get better battery stats from the market or from this link here then set the display options to "Partial Wakelocks" "since unplugged", remember you do this after using your phone normally from 100% to 50%, this should be able to give us some insight into what is eating your battery, it may be better to let the phone sleep as much as possible, but I know it's pretty hard to leave the device alone......

My non rooted galaxy s ii lasts at least on full day of heavy usage, including 3g, music, and gps. Will last 2 to 3 days if i use it conservatively turning off 3g when not in use.
make sure u have latest update thats basically all i did.
good luck.
Hey, so I've seen several people claiming fantastic battery life, etc. So, I am just wondering what's your experience in general. If you've got some free time and feel like typing, can you list several things like:
roms & kernel
stock/anker battery
battery life
screen time (and possibly voice call time or whatever else that seems to consume lots of the battery life)
highest battery temperature (I recently got pretty high so I was kind of worried)
and anything else you think might worth sharing (favorite actress? :silly
As for me, I recently installed Speed ROM 6.5 with stock kernel on stock battery
I only got 8 hours battery life to get to 14% with 3 hours of screen time (mostly used for game, browsing, and flipboard)
I got up to 100F (~40.5C) after playing a game for about 15-20 mins which made me leave it for a few mins to cool down. The next time I played the game again, it got up to 109F (~43.5C) after playing for 20-30 mins....
I am wondering whether that kind of high temperature is normal or not, and whether my battery life seems ok or bad; which is why I am hoping people can share their experience here. I haven't try using faux kernel though (might try it tomorrow in hope for a better batter life)....
So, again... if anyone got free time and feel like typing, please share it with me :angel:
From my g2 to this phone all I ever see is how bad the battery is. Never noticed a difference switching roms and battery across all smartphones I've used is allot what I expect.
Some people just can't be happy you know. Not to mention people never agree on anything (me included ).
Just my two cents

Well, first off, I am not trying to complain about the phone here. All I am asking/trying to find out is whether my experience is "normal" or not for Amaze.
I also come from G2 and obviously the battery life will be worse on the Amaze in general. This phone is 1.5ghz dual core and 4.3" display compared to 800mhz single core and 3.7" display on g2 with only extra ~300mah on the amaze.
I just want to know if my experience of getting only 8 hours battery life (with 3 hours of screen time consist of game and browsing) and getting a high temperature of 109F on the battery is considered "normal" or not for this particular phone. I only have one phone here; so, I don't know if my unit is bad unit or if it is normal for the Amaze.
So again, by all means, I am not trying to complain about this amazing phone here. I am just trying to find out if this is what normally happen with this phone.
And yeah I'm one of those guys that can never be happy :silly:. When I used G2, I want larger phone and faster performance. When I got Amaze, I want slightly larger screen and much better battery performance. So, yeah I can never be happy with my phone :laugh:
The temperature thing is definately normal, it can get pretty high. I've had it go above 109f while on video chats on Skype. As for thebattery, that's normal too its just dependent on the user. U may have something that's running continuously in the background that your not aware of that's causing drainage. Many things that could be effecting the battery really

@OP, most likely you either have a bad battery, or your phone isn't sleeping properly on idle, or your phone has some problems with the RUU
Code:
Battery is ~1900mAh. If you use it for 3 hours active at around 400mAh, that is 1200mAh
700mAh left for idling the rest of the 5 hours. My idle current usage is around 9-40mAh as reported by Battery Monitor Widget(go to settings, change monitoring mAh to HTC Sensation to get a better reading)
700/5 = 120mAh/hour.... this means your phone isn't sleeping properly
Get CPU Spy... install it, then put your phone down for an hour without using it.... after that, does the report show that it goes to deep sleep?
When I got my phone and flashed the ENERGY rom, I had ~8 hours of total uptime (1-2 hours of usage)... i reflashed the RUU (do it on 100% battery), then it is better now
Now, on the Energy STOCK ICS rom with FAUX latest(0.12?)
Anker battery
15 hours of uptime
1-2 hours of screen-on time(roughly 2-3 hours of phone "awake" time)
don't remember battery temps, but i don't ever remember ti being that high
interactive governor, max frequency 1.4 ghz(to maximize battery life)
data on, autosync on, 2 gmail accounts synced only
My 100%->80% battery drains in 90 minutes, but after that, it slows down
I added the following to build.prop to tweak more battery life
Code:
# Power Save Tweaks
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
If you really want to stretch out the battery, change the governor to powersave(forces processor to 192mhz always), but it definitely lags and I wouldn't recommend it unless you really really need to max battery life
EDIT: Go to Settings->power->see what is using my battery, post a screenshot (this one is 16 hours plus ~2 hours usage)
see the part that says "awake", and the part that says "screen on"? It should be correlate mostly -> when you use your phone's screen, the phone is awake.... when you turn off the screen, the device should be sleeping and not be awake

I guess this phone is just that "hot" eh....
So, you're saying that I should be able to get a better battery life than that?
By the way, did you use Juice Defender or anything like that? Or did you just let your mobile network and wifi on all the time?

Hmm... I would try to check the stuff that you said. I did see the battery use like you did and I have much more awake (since I used it for games and browsing continuosly). But, when I was not using it, it doesn't show that many "awake" status which is why I thought that Amaze battery performance is just that poor. I forgot to try third party app like battery current widget or cpu spy. I will check those out.
Did you use Juice defender or anything like that? Or, did you just set them manually when you need it?
And I did leave my WiFi and auto sync on.... From your usage, I'd assume you turn off your WiFi when you're not using it, right?
Thanks for the input
Edit: So, I am guessing there's a rogue app on my phone? I just reboot my phone, leave it for a minute, and battery current widget shows 200mA on my notification bar
From what I'm reading your a heavy user. Like me lol. The most I get is 6-8 hrs. With 1.5-2 hrs screen on time. Comparing that with others who get double digits It's nothing but I'm a heavy user. I stream Pandora daily surf the internet for 1 hr non stop, xda for most of the time. . And on weekends I'll have most 4 hrs. But 3.5 of those screen on with data streaming and screen on with out going off. Kinda like watching a netflix movie on mobile network. I use my phone like if it is my laptop now. I rarely use my laptop. I don't have internet nor WiFi to connect to. But if I tether I would run out of data faster so I avoid it. Besides battery draining faster.
I think there is a difference between:
1. leaving the screen on for a while, causing the phone and battery to get hot. Specially when gaming because CPU is constantly running.
2. And total screen on time accumulated of 2-4 hrs screen on. Which is achieved when sporadically checking phone for text, calls, email, quick surfing. Then shutting of screen through out the day.CPU goes to deep sleep phone stays cool.
Now that's what I call a heavy user.
Remember when phone is hot battery drains faster so you need to find a way to cool it down. Sometimes there are settings in cpu apps that when phone reaches certain temperature that app will force cpu clock down a lot as to use less power to start cooling down but causing lag.
I've got a 4 month old stock battery with latest faux kernel v.16 with battery saving tweaks on it. Energy rom stock 8-1. If there is anybody that reaches double digits with 6-7 hours 4g mobile streaming not wifi at all. 2 hrs without turning the screen off not 2 total hours. Please say I? I'd really like to know your secret.

Battery Current Widget... go to the options (top right), change the current selection(should be first row, then middle row) to "HTC Sensation" (it'll be more accurate)
that program doesn't accurately report mA if you don't change it(before changing, it'll be screen-off deep sleep 100mAh, but after switching, 10-40mAh)
I don't have Juice Defender on... autosync and data is on all the time
try w/o wifi on... i think wifi should take less battery power than data, but it always depends
on my screenshot, if you go back one and click on the screen-on... what does it say?
what does CPU Spy say about your phone going to deep sleep?

if you are only getting 8 hours uptime with 1-2 hours of usage, then your phone's not going to sleep properly... I'd reflash the RUU, then flash Energy ROM and faux kernel... i had that problem before I reflashed RUU (but that was before I knew more about CPU states and mAh usage on this phone, so I don't know if it was a problem with the deep sleep, or the phone not properly updated to ICS when I got it from someone else)
you want to try to max battery life? I can give you hints to hit that mark... it's all about physics/electronics
your battery is 1900mAh.... Using Battery Monitor Widget(with the Settings changed to detect the phone as "HTC Sensation", see above)
With the tweaks in my first post of the build.prop, BMW shows my idle around 10-40mAh..... 10 hours of idle = 100-400mAh. Note, this is with sync and data on... if you use Juice Defender or data off, probably less
So, idle, you use up 400mAh... you have 1500mAh left
1500mAh / 6 hours = 250mAh each hour.... with BWM, it shows that the current usage goes between 100-500mAh depending on how much screen brightness, data used, processor speed... If i choose powersave, I think it goes between 50-300mAh, but its really laggy, noticeable
300mAh * 6 hours = 1800... close enough
to avoid the 100%->90% fast drain, employ bump charging:
either
1) charge your phone to 100%. remove plug, wait for it to drop to 90%. replug it, charge to 100%... repeat for 5-10 times
2) charge your phone to 100%. remove plug, shutdown. Replug it, wait till the light goes green, boot up, charge to 100%, remove plug and shutdown, replug it , wait till light goes green etc.... do the cycle for 5-10 times
I was trying to see how much I could get out of my phone. I used my phone as little as I could, putting it into airplane mode when I slept.
ROM and Kernel: I was using the latest build of Energy and Faux Kernel v.15 at the time of the picture
Using stock battery, unfortunately I do not know what the highest battery temperature is.

unfortunately, for this device, the screen brightness and dual-cpu takes up a lot of power... if you see the pic below, when you use your phone(screen-on/awake), the battery % left has a sharp drop
I know for my old phone, LG Optimus T, I didn't have a data plan... the phone had data off all the time, and I got days out of using it(phone calls, wifi/browsing, checking gmaps offline)... once I enabled a data plan, it got half (like 1.5 days instead of 4)
if you calculate your usage... its possible
24 hours * 50mAh during idle = 1200 mAh
2 hours * 300mAh/hour during screen-on usage = 600mAh
total = 1800mAh, the capacity of your battery

So if I use either of those 2 methods above, is my battery 'cured" of the 100% to 90% fast drain? Or do I have to keep doing it over a period of time?

bump charging only helps you for that one time... you have to do this every time if you want max battery capacity
the problem is 2 things
1) the hardware/software is configured to maximize battery lifespan, meaning to slowly charge it and not go to 100% (high voltage, damages battery)...
2) the hardware/software is poorly coded, can't read the battery voltage properly...
either way, doing this means you are forcing current into the battery every time... your battery will hold less charge in a few months if you force it to full everytime... so you have to get a new battery aftera couple of months or live with lower capacity
I will just try to observe it better tomorrow using all those apps. With much less usage (1.5 hrs of screen time), i only got 11hrs of battery life. The screenshot below is for those 1.5hrs f screen time... I dont use jd and got email sync every 1 or 2 hr though....
Sent from my HTC_Amaze_4G using xda app-developers app
I tested the idle-deep sleep capacity of the phone...
got 21 hours idle, 17 minutes screen-on (minimal use of phone) with 50% left
here is my phone with data and auto-sync ON, I got roughly 10 emails(all received during different times), had about 10 minutes of phone calls
NOTE: around the first part of the graph, you see the %-left spike up... I rebooted my phone then... and you can see that the battery-monitoring software/hardware part recalibrates itself to the real value
NOTE: cell standby-time of 21 hours used more battery than screen-on of 17 minutes.
When I used the phone for another 15 minutes, screen used 35% of battery while cellular standby dropped to 22%
tl;dr, using the phone, especially the screen, kills the battery a lot more... not using the phone = lasts a long time

I guess after using all those apps that you mention, I can kind of see that Amaze battery is just way worse than my G2. I was pampered with my G2 battery life for a week and now I realized how bad Amaze battery is. lol
I got 11% left after 12h 15min. That's about 1550mA used (I use stock battery).
almost 3 hours of screen time (3*350) = about 1050mA
25 mins of phone call = ~120 mA
about 8h 45 mins of idle = 360mA
So, yeah, it summed up about right this time (more accurate compared to my first result where I think I got a rogue app)...
**I am eagerly patiently excitedly waiting for a fully working stable CM9 by sport :angel: **
On a side note, just wondering if anyone know if galaxy s2 have better, worse, or about same battery life? I am just curious since s2 is supposed to be amaze rival at t-mob....
Here's mine
Rom: Fourth Bar Jellybean Fusion
Kernel: Faux's Kernel, latest edition [August 15th]
Average Temp: high 90's
Average Battery Life: 5-6 hours.
Realize that what you do with screen on makes a significant difference- If I play organ trail(awesome zombie game styled after old school oregon trail game) I can play for a long time with little battery drain.. but it is a 2d game, and not going to be very processor intensive. If I play final fantasy 3, a 3d game, wow.. battery will drain much quicker, but then again, it IS a 3d game, and processor intensive. So HOW you use your phone is even more important than the screen on time.
With the latest faux(17) kernel, and 2-3 hours of screen on, the last few days I have 45% battery left after 15 hours since unplugged. Maybe 30-45 minutes was organ trail, but not much other gaming. The only changes I made, were made to the kernel, which I posted here(be aware that making all those changes will create some small lag changing screen orientation or opening app drawer, but haven't noticed anything else). http://forum.xda-developers.com/showpost.php?p=30298629&postcount=4
I also underclock to 1.2ghz- this doesn't create any lag, and no game or app I have used seems to work ANY better @1.5ghz than it does @1.2ghz. The main difference is the voltage it uses at max speed will be less @1.2ghz.
If you have weak 4g signal, there is an app i recently posted in some thread that puts it on 2g while screen off.. that has helped a lot too. If you have constantly good signal, then it won't make MUCH difference(tho 2g does drain less than 4g even with good signal), but it takes up to 2 seconds for it to switch to 4g after screen on. I can wait two seconds before opening an app, I don't care.
I assume you have used betterbatterystats to see what apps keep your phone from deep sleep, under partial wakelock?
And when I get obnoxious drain, but NOT because the phone isn't going into deep sleep.. I turn on the logging of an app called currentwidget- it can actually measure the MAH used while using specific apps.. the app itself can cause a bit of drain, but you'd only use it long enough to see what app is so battery inefficient. I have more about how to use that under battery savings part of the bible in my signature.
Edit: And I consistently get battery temperature of 77.7-77.9F, I always have, no matter the kernel or rom or settings.. perhaps it raises a TINY bit when I play some intensive game, but never noticeable. I am using an anker battery tho, so if you are using stock, perhaps that is a factor.

Good to know that. I used a different app to check the current mah and it seems reasonable. I forgot to use better battery stat; but, based on cpu spy, the deep sleep time seems about right... I haven't updated my kernel to v17 (still on v15) and haven't done any edit that you mention since I was still switching roms to find the ROM that suits my need. I might try to do those stuffs today and hope for the best.
And btw, I am kinda jealous with your battery life... 45% left after 15 hours unplugged and 3 hours screen ON
I might get similar result; but my battery left will be 10% and those screen on are mostly on flipboard, xda, and browsing....
Like right now, 6h 10min unplugged, 40 mins of screen on (xda & flipboard), and I am down to 66% :crying:
**On a side note, I just get my hand on gs2 and I am just curious to try and see how good it is since gs2 seems to be such a hyped up device compared to amaze.... :laugh:

Just checked my usage. I'm sorta similar to yours in terms of screen on time. 11 h 43 m since unplugged, 39 min screen on (facebook, news, texts) and I'm down to 62%. My screen on time isnt that high, yet something else is draining my battery.
Awake time is 1 h 44m. Lots of Alarm Manager partial wakelocks. need to figure out what's causing those
Hi,
I just bought an S3 over the weekend, so far it has been a delight to use and I have a question or two regarding the battery life. I am finding the battery great when I am using the phone, it drops much more slowly than I expected a 4.8" quad-core monster to do It is just the standby time that is concerning me.
Is it normal to have the battery level go down by about 20% overnight? For example, when I went to bed (about midnight) the battery was at 77%, this morning when I woke up at 7am the battery was showing 59% when I dismissed the alarm. That's 3-4% per hour. Running stock, unrooted, XXBLG8.
By comparison with other phones I've used, a HTC One S C2 loses about 2-5% overnight. I do notice that the HTC seems to switch the WiFi off for a good part of the night, though.
Also my phone seems to be suffering the 'cell standby dominates battery usage' issue, but as I understand it that's a bug with how the usage is reported and isn't related to the actual battery life.
You have to flash a cell standby fix or something to make it report the battery life correctly.

You have to use Betterbatterystats and run it and detect what uses your juice.

There next you have to unbloat your phone. Remove or freeze with Titanium backup

At end your S3 have to use max 2-4 % per night wifi and wcdma switched off on gsm mode.
All of the above suggestions worked to reduce consumption while sleeping for me.
Cell Stand By Fix was the biggest help.
Have you made use of any of the built in power saving options?
Another big help for me was setting the wifi to remain off while the phone was locked. Seemed to save a lot of battery power. Not a setting for everyone, especially if you require receiving emails, or other data related msgs while you sleep. If you can wait until you wake its worth a shot.
Thanks.
I've installed BetterBatteryStats and the Battery Monitor Widget to get a better picture of what's going on. Hopefully it will be just be a rogue app or two that I can just blow away.
Also noticed with WiFi Analyzer that the phone's WiFi reception in my bedroom is quite weak (happens with all the phones I've tried but not the iPad!). That's probably making any problem worse.
Using TB to remove the bloatware needs root so I'll wait a week or two before rooting; I just bought the phone and want to make sure there are no (obvious hardware) defects while running on stock first

That fix DOES NOT reduce battery consumption. If only fixes that in the battery graph standby is reported to take a bigger share (10x bigger) than it actually does but does not affect the "charge left" calculation in any way.

For one, apps like Juice Defender may help a lot: they can disable data network or Wifi and periodically (I typically used to set it to 30min) re-enable it so the apps still get their sync, then disable it again.
Alternatively,making the phone fallback to 2G data network will allow you to realtime-snyc without draining battery. HSPA standby seems not to drain noticeably more than 2G on the i9300, but fast dormancy doesn't work everywhere correctly so your mileage may vary.

It's not normal. I'm on stock rom but rooted and undervolted. Mine only consume 1-2% during sleeping time. It's better to know what causes the drainage. Use betterbatterystats. Then you will found out if it's an app or your carrier. Fast dormancy is enabled in other carrier which leads to better battery consumption during idle.

As already stated, the cell standby fix has nothing to do with battery drain, it fixes a wrong reporting of cell standby stats, it will NOT sort out battery drain

He is right. There is an actual battery drainage and not a reporting problem.
I lost 5% (100->95) in 9 hours overnight ( while not touching at all )

Those are my battery stats with wifi off and no clock alarms.
Killing tasks is just a precaution in case some background app is running.

Anyway I am including some screen shot
I have been getting between 3.5 to 4 hours of sot
No gaming just some videos and browsing
Also my accubattery says my battery capacity is 3600 not 4000
Also chrome Has been pulling alot of power
Is it just my phone? Should I return it?

Hmm I am thinking because the phone has to adjust before the battery runs smooth
Otherwise I will have to return it
I returned a op5t because I thought the battery life wasn't that good but damn the mate 10 pro is worse.
My battery life is very good
Normally 6 to 7 hours sot
One time I reached 9h so
Also accubattery stated my battery as 4150 which is over the rated capacity ?

As it was stated many many times, unless you are playing or watching movies,videos, you wont get much sot just by using apps like social, emails and stuff. You should look at how many hours your battery lasts. Im getting 4h sot at most, but the battery lasts about 30 hours. Im using a lot of social apps( fb, meesenger, instagram, whatsapp video call), emails, surfing web, listening to music 2h per day, and so on. Im very satisfied with the battery because it takes me through the full day without any problems, whatever ill do on my phone.

My battery drain overnight is between 1 and 4%. Doesn't matter if it's on Wi-Fi or 4G... same result. I have Facebook and the usual social rubbish installed.... does sound like a rogue app.
I find the battery life of this a monster... 2hrs of youtube and my s8+ lost 24%.... My mate 10 pro only lost 16%... scale that up over a day and this thing goes on forever....

How do you get this low standby drainage? Mine loses around 8% a night even when running phone optimizer before going to sleep.
Unfortunatly it says only 93% battery health already at 3670mAh.
Dunno how trustworthy this is anyway, when charging at around 20% according to accubattery 1% equals 41mAh (that would make a 4100mAh battery)
but when charging at 90% accubattery says 1% equals 36mAh (equals 3600mAh battery)
From this I conclude that the Battery Health displayed by this app heavily relies on your charging habits.
The dude that supercharges every morning for 20 min thinks he has the biggest battery, the guy who keeps his phone plugged in the office thinks his battery sux
for this health feature id recommend charging from 5-95 for 5 days in a row... i think then we will have more accurate results

Nothing special.
I put in manual mode most of apps except apps I need to run in background.
I disabled Chrome and use Samsung browser, more battery friendly imo.
I'm on evie launcher but I had same stats with emui launcher.
When I sleep I put phone in airplane mode most of the time (because of waves) and I lost 1% and if i let data on, I lost 2 or 3 % per night (I sleep 6 or 7 hours max you know everything now ?).
According accu Battery, I have only 3788 battery and not 4000 as indicated by huawei.
The battery of my Huawei Mate 10 Pro was a monster until recently, last few days to be exact (maybe the last week). It drains 20% ish during night as well now (was 4-5% ish before). No apps draining, it's the system.
From 95% to 9% with 2h15m SOT last night.
Also seems like quite a few users have the same problem in the last week or so.

Nope. Only use the standard apps and have apps like Facebook, Spotify, Netflix++ installed. I'm at 80% now and the system tells me I got 12-13 hours left of use!?

Yeah, did it this morning. The 12-13h thing is probably wrong though, I've just lost 4% the last 5 hours now.
Looking at the graph from this nite shows the drain was normal, then suddenly after 2-3 hours of sleeping the battery started draining fast. Weird.

Perfect, watch stats few days and give us a feedback.
Put off your phone and reboot may help
