[Q] Webbrowsing drains battery? - AT&T Samsung Galaxy S II SGH-I777

I noticed that with all I'm doing to save battery (GPS, Bluetooth, 3g off, brightness on the lowest setting in the browser and general) its not making much of a diference in my opinion. I even under clocked the cpu to 500mhz. All I want to do is webbrowse for an hour or so throughout the day and yet it seems to use more battery than I believe it needs to. I have about 35 minutes of display time and 10 minutes of web time and my phone has already lost 7%. This doesn't seem normal to me since I've lowered everything possible of the phone. Does web browsing use a lot of battery in general?

I typically use about 16-20% of battery for every 1 hour of screen time, so yeah your running about normal to a lower than normal drain level.

I try everything to save batterylife. Using the browser sadly is a good way to see your phone's battery life dissapear. Especially when browsing forums with white backgrounds.

I tend to agree with the other comments here. I usually see about 10% drain per hour of screen on when not doing anything data/processor intensive (i.e. reading an ebook) while my normal data is syncing in the background. I'd expect this to be improved if I turned data and radios off, but probably only by a percent or 2.
With more processor and data intensive stuff like browsing or watching movies, I would guess this would increase some. Extrapolating your data out would give you roughly 14% drain for an hour and 10 minutes of screen on with 20 minutes of browsing. Seems reasonable to me.

Battery Life

I know there are some people experience battery issues, but I've experienced none. Running on the latest build .15, This is after leaving it unplugged over night at 100% to then moderate use all day (Youtube, Email, Browser, Pinball, Sprinkle, Music, Camera, Video Cam).
I'm happy to say the least.
Cripes!!!
Is that with or without the keyboard attached?
Without Waiting for the price to drop a bit before I buy it, it will drop soon I'm sure.
The battery is so good on this thing it's not even an issue. I never check battery stats or anything like that.
Can go through a day no problem, always on performance mode.

I am sure that that battery statistic includes plenty of standby time, since it is unlikely anyone would be playing pinball for 24 hours
I get similar battery life with my Prime. A day and a half or more with moderate use and normal downtime (like when I am sleeping). I am pretty sure I could leave this thing sitting in standby mode for weeks and still come back to it and find usable battery life remaining.

same here and i just plug it in when i get home.
On update .11 I was getting 2 1/2 days (tablet only) with the same moderate-heavy use, always-on WiFi. About 4 days on standby.
Update .14 I guess is doing better than .13, but I only get 2 days with tablet+dock and about the same usage as before. Haven't tested standby.
I've found battery life to go like this on .15, with auto brightness (which usually finds a good level for me) and Balanced battery setting:
1. Around .375%/hour on standby. That seems excellent to me, particularly considering that I keep wifi on and everything syncing in the background. I can't imagine getting better standby battery life unless I turned everything off, which I don't want to do. I like it that my Prime is up to date when I wake it up.
2. Around 7.5%/hour when doing things like ebook reading, VERY light browsing, etc. That also is excellent, meaning I can use the things for ebook reading for over 10 hours. Can't ask for more than that. Note that if I read outside in direct sunlight and Super IPS+ mode turns on, battery life is cut SIGNIFICANTLY. That's to be expected of course, and it's just as much of an impact as I imagined.
3. Around 15%/hour for heavier browsing, ebook reading, watching video, casual gaming, etc. That's a little less than I'd hoped, coming in at around 6.5 hours total.
4. Around 30%/hour for heavier gaming (e.g., Shadowgun). I'm not sure if that's good or bad. Seems like it's excessive, but then again this IS pretty intense gaming.
I can help these scores a bit if I run on Battery Saver mode, which will work for all but heavy gaming. Funny thing is, according to CPU Spy mine barely ever pushes 1300MHz or 1400MHz, no matter what mode its in. It spends most of it's time at 1200MH, in deep sleep, or in the lower (100MHz-400MHz) range. I wonder if Nvidia still has some tuning to be, and if performance and battery life can still be optimized a bit--it seems to spend TOO MUCH time at 1200MHz when that kind of speed doesn't seem necessary, and TOO LITTLE time at 1400MHz when that kind of speed would be helpful.
Wow! Great battery life OP. That guy named Ickii needs to see this thread. He created a thread on his prime getting bad battery life.
Same results here though. Great battery life in balanced mode and very heavy usage.

Battery Usage Patterns

I thought I'd start a thread to track battery usage patterns, to see if we can identify some consistent... well... patterns across Primes. This is NOT meant to be a complaint thread, but rather to simply indicate how much battery is used per hour for given use cases. I realize there are bound to be many variations (e.g., how often email syncs, how many accounts are syncing, how much Flash is running, etc.), so I'm looking to just see if people are having the same range of experiences in terms of battery life.
Note: I believe that there's still quite a bit of tweaking to be done on how the Tegra 3 manages processor states. I think it spends too much time at higher states for some things, particularly browsing.
This is what I've found to be fairly consistent. All results are on lowest screen brightness except where noted, Balanced mode, undocked, in good wifi range, and running .15.
1. Standby (with wifi connected and background sync running): .3%-.5%/hour.
2. Light use (ebook reading, email, calendar, task managers, etc.): 7.5%-10%/hour.
3. Video (e.g., HBO Go in the browser, YouTube, Netflix): 10%-15%/hour, with brightness at about 30%.
4. Browsing (with Flash on-demand and moderately used, stock browser): 15%/hour consistently. Includes apps that use the browser, such as Google Reader.
5. Gaming (pretty much any game, from Angry Birds to Shadowgun): 30%/hour consistently.
6. IPS+ Mode and full brightness, light use: 30%/hour. IPS+ mode is a killer, but worth it to me for sunlight visibility when I need it.
For me, battery use is quite acceptable across all use cases except browsing. It makes little sense to me that viewing video (with higher brightness to boot, and including video running in the browser) would use less battery life than browsing--perhaps they've charged up processor speeds when the browser runs to overcome some inherent performance issues with it?
If you've made note of any consistent battery usage patterns like this, please report them in this thread.
These results are consistent with my experience, probably closer to 20% on the browser %. I'm also surprised at how quickly the browser uses up my battery. I've tried using different browsers and have noticed no appreciable difference. I've also set everything to manual sync, except for Gmail. I use the balanced mode with screen brightness set to approx. 30%. I almost never use Flash when browsing.
Nobody else wants to weigh in?

Naturally I don't particularly want to screenshot my usage over an entire week or anything, but here are my general figures so far on update .15 with all my apps as I see it.
Again, I don't have anything backing it up and haven't done detailed analysis on battery drain since .13, but I generally get 3 days with varying use including hard gaming for short stints.
1. Standby (with wifi connected and background sync running): .3% (pretty consistent, but some times the Prime won't enter Deep Sleep which unmercifully consumes)
2. Light use (ebook reading, email, calendar, etc.): 5%/hour
3. Video (Netflix): 8%/hour, with brightness at about 10%
4. Browsing (with Flash always-on and moderately used, Opera Mobile): 15%/hour
5. Gaming (set to Performance, OC'd to 1.6 gHZ): 35%/hour
6. IPS+ Mode and full brightness, light use: 40%/hour
My tab wont deep sleep only when docked. Sometimes I lose 4% an hour sleeping while docked.. pathetic. When not docked I can see with battery monitor widget that I lose 1% every 8 hours

Mine goes into deep sleep when docked no problem, and standby usage remains about the same.
But, I don't want to derail this thread. It's about usage patterns when undocked, specifically to avoid throwing the dock into the mix as another variable.
Just wanted to resurrect this thread, and ask if anyone is having a problem where reported battery life drops by 2% periodically instead of 1%. Seems like there's a glitch either in how the system is reporting battery life.
See the attached pic... Notice 70% to 68% and 59% to 57%.

It's not updating or syncing or something? Do you use a real-time monitoring widget, or multiple diagnostics apps? These things will tax the system here and there for their information won't they?

I just use the Battery Drain app, and all it does is poll every minute to see what battery life is at. I suppose the app could be skipping a minute, but then I'd hope it would adjust and not report twice the usage/hour. And, I'm pretty sure I've caught the battery life dropping like that outside of the app.
Thing is that it's not just using more power per hour according to the app, but that it's dropping the 2%. Just a minor mystery...

[Q] RAM and battery life

The mediapad is my first tablet. I just bought a second hand one, and two things trouble me:
1) The RAM in active processes is displayed as 512, should it not be 1GB?
2) battery life seems too low, something along the lines of 3 hours of mainly google play use. I have high resolution set, active wifi, had no sim inserted, though plane mode was not activated.
A lot of devices display less memory than you think they should, it's ok don't worry.
Yes the battery does not last very long...

mediapad battery life
If you go to settings/applications/running services you should see bar at the bottom of the screen indicating free and used ram. Mine is standing at 191MB used and 434MB free at the moment.
I was going to ask about battery life myself, so here is a question for all other mediapad users: How much "screen on" time do you get per charge?
No matter what I do, I can't even get close to 6 hours that are specified.
The best I got was 5:15, and that was offline (wifi and 3G), brightness on minimum (bedtime reading), JuiceDefender on.
Only apps I was using were Adobe Reader, ComicRack and Amazon Kindle.
If I use Opera, Facebook, YouTube, StumbleUpon, News360, I get about 4 hours of "screen on" time.
When I look at battery usage breakdown in settings, display or wifi are never at the top. Usually there is AndroidOS or Android System, followed by some of the apps I was using.
If I play GTA3 (ver1.3 works great btw), it drains about 20% per 15 minutes of playtime.
On occasion it happens that battery drains at usual rate to about 15%, and then the shutdown countdown begins, as battery drops from ~15% to zero instantly.
Also, sometimes when it drops to 20% goes back to 30%, then from 10% goes back to 20% and from there drains to zero normally. It drives me crazy as I'm never sure how much juice I have left.
Tried to use Battery Calibrator app, but still the problem still persists. Can't root, still have year of warranty left.
Do you guys have any similar issues, how do you cope? And don't forget to tell us your "screen on" times and typical usage.
Thanks!
I know this might be somewhat of a gravedig but I really need to correct things a bit...
With WiFi on, screen brightness down and constant screen on + surfing / reading I was able to squeeze out 7 hours and 10 minutes out of the battery, starting at 100%...
The battery really is awesome! Just make sure to turn off things you dont need (Bluetooth, GPS, 3G / Mobile Data, Screen Brightness).
I'm surprised, in a positive way.
The only problem I got is with the touchscreen shaking and at times not taking my taps.

New Battery

So I started a new thread cos its kind of different to my other one. The last little niggle with my Prime seems to be the battery. I read the instructions for once and it said to charge it all up. So i charged it till it was green and then powered it up for the first time. So as the instructions say i need to break the battery in. At the moment i am getting about 5-6 hours. The pad is on balanced with auto brightness. Does this seem normal for new battery. I would hope to end up with 9-10 or are my expeditions too high?
From what I remember the instructions stated that for the first time you should leave the prime charging for 6 to 8 hours. I personally didn't follow this and I'm still getting pretty good battery life. My advice is to let the battery drain out and charge it to full again and leave it connected for at least a couple of hours. The battery should calibrate itself through a couple of charge/discharge cycles and get better over time. Forgot to add, I have my wifi set to turn off when screen goes off.
If you're on firmware .21 it may be due to wifi. Check your battery stats. I have great battery life but as soon as i turn wifi on and use it battery goes down waaay fast.
I hope the new firmware thats coming adresses that, because before .21 that wasnt the case.

Lol i was too eager and only charged my prime until it reached 100% at a mall. But i still have great batterdy life

People that didn't fully charge it up the first time for 6-8 hours, exactly what kind of life are you getting and could you please explain what things you are doing on it. I didn't charge it fully and it accidentally got turned on during its first charge.
Thanks,
If you are on .21 don't expect the battery to be near 8hrs while on wi-fi surfing/video/screen on/etc. I had it on .15 for 2-3 days while deciding if I wanted to root or not and it was near 8hrs wi-fi on. I'm also hoping for the next update to fix whatever they implemented in .21 that's causing a significant amount of drain.
I am on 4.0.3, is that the right one
Sorry, wi-fi is .22
Thr charging over night for 10 hours or whatever is nowadays just a Myth that came from the old NiCd batteries (It was true back in the day), new LiPo / NiMh batteries have no Memory Effect and the first charge is nowhere near as important as with old ones.
In fact is actually better not to stress the battery doing full discharges / charges cycles.
These batteries get to their full capacity after about 10 charging cycles.
So if you didnt not charge X hours for the first time, dont worry, yout battery ill work fine.
The only thing that should be pointed out is that if you use very often your battery, every 2 - 3 months is recommended to let the battery discharge to 0% and charge while off to 100%. If you dont use the battery often (always connected) then is better once every month. Thats to keep the internal chip from the battery calibrated.
Well atm i am draining it down to <10% then charging. Is it ok for these modern batteries to be left on charging past 100%?
Battery life still seems pretty poor after 3 0-100 ish charges. 1-2% seems to last less than 5 minutes when on the net on balanced mode and screen brightness mostly down.

Yes, once the batteries are at 100% they stop charging. You can have them 100000 hours connected.. and they wont go past 100%.
im on .21 and i get great battery life. i never cut my wifi off. its on 24/7. battery drainage will more so be dependent on display brightness and what you are doing. wifi is already a known, wifi on any device drains battery at a faster rate than wifi off. it takes power to make wifi work ya know..lol i can easily get 9-10hrs. + with my brightness set to less than 25% & wifi on all the time.
also the two biggest drainers, as far as programs go, is gaming and web surfing. especially web surfing and especially while using flash. since web browsing is very ram intensive. I've noticed some browsers drain battery faster than other. Meaning some browsers are more optimized than others when it comes to power consumption. This shouldn't be nothing new. Everyone's battery drainage will be different because people use their device in different ways.
we have an update about to hit us any moment or day now so don't get too stuck on battery drainage on .21. it'll be time to test how it is on newer firmware.

Web surfing and gaming and WiFi are 3 major things in this tablet, what should we use it for then??
here are some battery saving tips!

That's what I'm saying. Everyone web browsing and gaming is different. Some web pages people visit might be loaded with flash content vs. Someone who visits a site with less flash content. The one with the loaded flash content will drain or use more battery than the other one. Same with gaming. I might like to play Dead Space or Shadowgun and you like to play hang man or some other simple game. The battery will drain faster with me playing the 3d graphic intensive games vs. The person who is playing simple or less graphical intense games.
Wifi is a must have and no way around that if you want to web surf. The amount of screen brightness, 3D gaming, and web surfing will influence how fast your battery drains. Wifi drains battery but not at a faster rate than those other things listed.
I think some people here expect to have brightness up to the Max with super ips+ on, gaming and web surfing all day and expect to get 10+ hours out of it. Lol. Its not happening. There are easily things you can check for and change to make you have better battery life. -
-First one being not to use auto brightness and don't have brightness higher than 25%. That's if you so concerned about making the battery last long.
-Second thing you can do is go into settings and change screen off display settings. I have mines set to 30 or even 15 secs. That means once 15 secs. Or 30 secs. Pass and I haven't touched the screen, the screen will cut off. That's a huge battery saver right there. Because my screen isn't on as long when its not in use.
-Third would be to go into settings and lower the frequency of sync settings. I don't need my email syncing every 5mins. Or my Facebook syncing every 5 mins or etc.. cut them down to maybe every hrs, or every 12 hours, or once a day. The best would be to sync when you open up the app instead of it doing it automatically in the background. Completely cut off sync to apps you never use. Constantly having things sync in the background is a major battery drainer when the screen is on or even while device is sleeping. If you put device to sleep and its always waking up to sync data, don't be surprised if battery drains at a faster rate during sleep or when device is awake.
-Fourth, cut of unneccessary sounds. Do you really need the keyboard or screen presses to make a sound when you press it? If so, don't be surprised your battery draining faster.
-Fifth, cut off that stupid vibration motor. Do you really need your tablet to vibrate when ever you press something on the screen or keyboard? Do you really need it to vibrate when your gaming? If so, don't be surprised your battery is draining faster then. Because everytime that vibrate motor goes off, it drains battery.
SIXTH, you can go into settings and have wifi cut off when device is asleep. Or you can go into Asus customized settings and have it cut off network activities when the screen is off or device is asleep.
All very easy steps people can take. Same thing as in saving gas in a car. There's things you can do or not do to make it last longer.

It does seem to be getting better though. I have had it on for over a day now and it is at 50%. Probably had a good 3ish hours of actual use. During the breaking in of the battery stage is it better to let it drain then fully charge or charge whenever I can?

Well hopefully after a few charges I will make my way unto that region, I think it has climbed though to a closer to 6-6.5.

Share your battery life & temperature please

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

sorry someone had to say it
@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)

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

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

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?

@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

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?

Maybe you should try to mod the Atrix Lapdock... if it works, you get a larger screen and a 35W battery

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
