[Q] Battery's lifetime suddenly halved? - Galaxy S III Q&A, Help & Troubleshooting

So I have a Galaxy S III which I absolutely adore. Some time ago, though (2 weeks maybe?), one of its biggest cons - the battery life - disappeared. Earlier, I could be sure that the battery held around 3 days of my regular usage (some emails, games, web) being left with around 20%. Some time after the update to 4.1.1, the battery started to have good and bad days - sometimes it holds just as it used to, other time it's a half of it (15% after 1 day and 7 hours with no games and almost no web? Come on!). I thought it was because of Google Now so I disabled the geo-locating options but it's no better. When I go to the battery usage in the menu, it shows me that Android takes 38%, idleness 24%, the network 21% and system core 6%. The screen or Wi-Fi are just 5 and 2 per cent! What's wrong, then? What should I try to do to get back to normal with the battery?

Awesome battery life

I have a galaxy S and as you may know, the battery needs charged everyday though I have heard of some that the battery lasts for a few days (that's 3 days).
Anyway, my sis has got a Galaxy Ace and while she's been away I left the phone off charge and had a look in every day to see how the battery was doing. I did install a couple of apps on the 4th day so that's why the battery graph when down faster.
The firmware on the Galaxy Ace is v2.3.4, the latest beta installed with Odin, and I had to select the English language from some Eastern European language which was a bit perplexing.
Anyway, Wifi setting was off after screen off with Google Sync on.
The battery was in no wise empty when I took the screenshot.
Looking at the graph I was losing about 10% a day !!! so I reckon without using the phone at all, just in standby, you could get 8-10 days standby.
But what's a smartphone if it's to be left on standby?
My very old motorola basic phone could last 7 days with usage of messaging. I'd say that a phone has good battery life if it meets entertainment/connectivity demands and could still go on >2 days which few phones can...

Android OS bug and how it affects us all

This is not a battery thread. I just wanted to do some maths based on some findings of my own.
I post this screens, taken at 50% battery. I rebooted when full battery for a fresh graph. I'm running "stock" 2.3.4 KG1. Data is always on, two push mail accounts, display on Auto, no gaming, no photos for today.
So, if the graph are accurate (I really doubt that):
1. 17 hrs 38 mins total time on for 50%
from this:
-1 hr 48 mins phone calls
- 45 mins Android OS
-1hr 2 mins display on
-Android system (the thing responsible for widgets, push mail and so on, basically for apps) 7 mins 50 secs!
-Phone idle 16 hrs 35 mins. TIME WHEN NOTHING IS SUPPOSED TO BE RUNNING IN CPU FOREGROUND
- Navigon comes up with 11% BUT I NEVER USED IT- and there are no details on CPU usage either.
- I used 20 mins of sync Wifi for the later part of today, wifi doesn't show on the graph- no clue why.
Here I stand pretty puzzled:
1hr 48 mins of calling + 16 hrs 35 mins of idle is 18 hrs 23 mins! assuming that idle does not include when calls connected and screen off .
Here are the figures for the AOS and how life would be without it.
Android OS chewed 14 % of the 50 % battery. Calling ate 43% for 1 hr 48 mins. If it wasn't for AOS bug, I would have had power to call for some 36 more mins to get to the 50% battery. That's like 30% more talk time without the bug.
Display, set on auto, drained 10% of power for 1hr 2 mins. Android OS bug stole almost 30 mins of display time for every hour . This is 50% wasted power.
Phone Idle is 4% for 16 hrs and 35 mins. So, basically, every minute under raging AOS eats 0.31% of battery. for every 1% the phone idles for 4 hours and 9 mins (and ideal stand-by time of four and an half days ). EVERY MINUTE OF ANDROID OS EATS AWAY 1 HOUR AND 22 MINUTES.
Also, the Widgets and all other stuff are actually consuming half the power eaten away by AOS.
So, if by miracle, the faulty driver is resolved by Samsung, we should get :
30% more talk time
50% more display time
350% more idle time.
Or, for the connoisseurs:
Android OS comes in, battery goes flat. No miscommunication. You can't explain that.
Good post, my own experiences (i only have my GS2 a few days coming from a HD2)
I deleted my battery stats last night and left my phone on,data was enabled nothing like bluetooth/GPS,etc,brightness is set to automatic brightness the phone was at 99% and from 12.29am to 09.59am this morning when i checked it was 83%,not too bad i suppose but could be better, i have fast dormancy disabled and i froze the Samsung apps with Titanium Backup,however the Android OS was at 41% and Maps and Cell Standby both 15%, since then ive been using the phone for some Internet, 1 call and sent a few text messages and it's now currently 12.41pm and it's at 47% and the display now shows at 35% and the Android OS is 23%, im running Lite'ning ROM 1.5, does this seem normal or quite excessive im in 2 minds myself, does the Android OS usually be as high as that when in standby,when im using the phone for a period of time it appears to go down as low as 8%.
All I can say is, use ATK. Its just working great for me.
Regards.

Thank you for this. It makes the problem clear to see. There are a lot of people saying things like "it all adds up to 100%" or "hey Android OS is high, but my battery life is very good".
As you say, we'd get much much better battery life if it weren't for this damn bug. Battery life can be good now. However with a 1650 mah battery, without Android OS wasting precious energy, it would be great...
Great summary!
More info
I have depleted the other 50% of battery so I'll post the values. The phone charged when connected to transfer the files. Well, at the end of the day, it looks like the that:
1. Voice calls drained 39% of battery for 3 hrs and 19 minutes.
2. Display is 2nd with 14% and 2hrs and 20 mins.
3. Android OS gets 3rd place with 12% and 1hr 20-this is the kernel running.
4. Android System- the one you bought the phone for- is pretty shy, only 9% . I repeat, here are all the widgets, Sammy updater, mail and so on.
...
Dialer is 6%, Navigon gets 8%, Cell standby - that's the radio FW- 5%
Phone Idle is the champ with 3% @ 31 hrs and 17 mins. That's the spirit.
Also, GPS status is eating 2,2% for every minute.
Bottom line: if it wasn't for the AOS, I would have had -see below( let's be real and give each process it's share so I'll split the AOS drain to get everybody happy)- before running for the charger .
1. Phone calls. 5.6% more battery- and 23 minutes more of talk time.
2. Display. 1.7% 22 minutes more.
3. Phone idle 0.9 % almost 10 hrs.
The rest of ~4% is shared for Wifi, Cell Standby and android system.
These numbers are valid for my usage pattern, phone calls all day long/ that's why i bought a phone for/.
I might draw some lines here and reveal some facts ( the values might be different according to usage pattern):
ONE MINUTE OF:
AOS bug drains 0.15%
Voice calling (I live on a good network signal area) depletes 0.13%
Display on is lower than calling @ 0.10%.
GPS could be chewing 2% when polled thoroughly.
Widgets and other Sammy crap are not scary at all. In fact, I find them pretty decent under this SW revision.
Maybe some will find these values useful.
Maybe we don't realize the impact of implementing a bad driver. For me, it all makes a lot of sense and annoys me more. Too bad we not on Icrap's ship, the news would have been all over the web.
One last thing though.
There are 2 main issues withSGS2: AOS and wake up lag. Never listen to any wise guy that says the lag comes from deep sleep and you should be lucky if you have it because it means the phone is SLEEPING and not eating away battery. I've noticed lately a trend in trolling this issue. I am confident that the guys behind this reasoning are on the same level with the guys that came up with Killing task managers and empty ram crap in Linux. And they even wonder why the alarm is not working after RAM flush.....
Wake up lag is a side effect of some nasty crap hogging the CPU's front bandwith. I bet any trolls here that when the lag is gone so will the AOS bug be ( at least AOS will be under Idle in %).
My wild guess is a radio issue somewhere.
same problem omg :S i hate this !! but phone is great !!
KG3 Report
Hi,
I have a new report to post, this time under KG3 stock rom. This time WI-Fi off whole time. I used the car dock for 10 mins.
1 day 7 hrs and 57mins from full charge to 15%:
Voice calls 2 hrs and 35 mins -37 %
Display on auto 2 hrs and 27 mins 20%
Android system 13 % Cpu total 10m 16 s
Android OS 9% 53 min 45 s
Dialer 6% C
Cell standby 6%
navigon 4% pops up,never used it
Phone idle 4%
Although it seems the AOS got less cpu with this, the improvement is not so clear. I almost talked 1 hr less with this one.
My android is 49% of 15 hour up time from last charge but the CPU time is only 2 hours 15 minutes for it. Hardly 49% of up time. Do you think maybe firstly there is no bug, its a bug with reporting not AOS usage time and that the phone hardware just eats a lot of juice even in standby. Just a thought. The battery lasts pretty good for the fact that its so small, there's an amoled screen and a dual core processor. Perhaps even in idle the hardware just draws a lot of power to allow a quick jump from standby to fully activated without any waiting around.

Could you post some screens?
Android system is 49%? the percents relate to the battery usage, not the time.
ALSO VERY IMPORTANT:
Dual core CPU should draw less power in standby/idle/sync. this is the idea behind dual/quad cores. If you have the time, read on how do they stack processes.
Deep sleep is not working properly. How come my WIN7 x64 wakes up in less than 1 sec from standby> win kernel is around 300 megs vs 17megs Android? It is a driver issue.

So instead of writing here, we should write to Samsung, correct? I hope this will be resolved soon, OTA update should do nicely!

Believe me, I've tried the highest official way there is. They keep blaming android/google. I even pointed them some apps that were using obsolete scripts and 4-5 ro.* that were hogging the cpu. All they answered is that is under revision. then somebody from the work asked me what the f*** is this communication about and told me to use the nexus S instead.
Here the results of a simple test I did:
KG3, CF-Root, 8 widgets, skype and viber, 2 e-mail accounts. The usage was roughly the same (mostly internet browsing, e-mail cheking and only a few voice calls 20min approx.) The difference is that in the first day I left the sync and WiFi on all the time. On the second day, I left both sync (including background sync) and WiFi off most of the day, except during the time which I was using it (browsing internet, updating market apps, checking e-mail, etc.) The result, as you can see in the screenshots below, is that with sync and WiFi off, I've got almost 26h extra of battery life (18h18min v 1d19h52min). So, for me at least, the battery drain is WiFi+sync.
Looking at the pictures, compare phone awake v screen on. With sync+WiFi, you'll see that the phone was awake many times with the screen off, whereas it didn't happen when the sync+WiFi was off.
Therefore, I think it is better to turn sync+WiFi on only when you really need it, and not all the time. That's what I'm going to do from now on.
Ah, no powersaving settings enabled in any case!
Android OS @2%
Still under KG3, nothing installed lately, nothing at all:
Full battery in the morning almost flat in the evening with very light usage- I on a sort of holiday ....
1. 16h and 2 mins it lasted
2. 57 mins of calling
3. 51 mins of display time
4. Android OS WAS 2 % running for a total of 3 mins
REALLY SAMSUNG?
I want my AoS back.....
i rooted the phone yesterday, screen on time was around 4 hours or so..10% drain per hour average with screen on-off.
freeze all bloatwares and aos went down to less than 10% (was in 40s).
will see battery improvement today.
after root, i still got the yellow rectangle at boot (havent remove it yet)..will it affect battery life? any input?
I froze the WIFI Sharing service and my phone went from dying 25% over 4 hours at work with almost no use (and WIFI off) to lasting all day, or not charging at night and lasting all night and through the next day.
Just saying.

If you don't understand that the yellow triangle ONLY means that the kernel you have flashed does not have the correct signature (i.e. it is a custom kernel) then you shouldn't really be messing with root at all. How would this be relevant to the AOS bug or to battery life?
What is your view on juicedefender?
Battery savers are pieces of **** that turn help battery life by constantly changing the device on something more like Nokia soap.
My Personal view on software that claim to help save on battery was/is as it is about task managers on Android... somehow useless mainly for a few reasons:
1. They interfere with running processes and I haven't seen one really optimized for the system. Some are behaving limiting the performance. Which isn't a good thing.
2. I found that even Watchdog is a drain culprit when it's running after a limbo limbo process.
I have seen this issues before, in PC world. 8-5 years ago, Sony was loading their Vaio series with so much crap that the laptops were slow as a turtle right from a start up. They failed to listed then and lost almost 60% of their market. Others reacted faster and gave the option of removing crapware ( mainly proprietary sofware and trial) when ordering [ btw,of course, anybody could do it by msconfig but few were willing to mess it...].
I can't get it why Sammy, HTC, LG won't offer a barebone/unified Android. We could all get what we need from Market and this is why we have the markets war.
I don't want my update service running in background, nor do I need email app from Samsung...in order to get them off my back I need to root, Edit a file and make sure I mount the right permissions( or BUY something to do it for me) and so on, most people don't want/can't root , not mentioning the longer the chain the more links likely to break, including the warranty is voided ...WHY all the fuss to stop something I don't want?
Microsoft hit the nail in the head with their approach to WP7 (except closing it like Apple). That's because they had to deal with screamers for 20 years and they have a clue about crap ruining an OS.
And yes, I am still waiting to see a dev coming out with a pure Android Rom on whole XDA.... for any device. They all add something to it....a tiny tweak or a tiny thing.

(Xperia Go) Battery Life

Hi I'm looking for a discussion rather than a Q so I chose this section.
I'm looking to chat with Go users about the battery life. How long does your battery last and what do you use it for? I notice that it
has a comparatively small battery but this doesn't always mean low battery - and I notice this phone IS being officially updated to Jelly Bean. I think the lower resolution screen helps keep the CPU and battery relaxed perhaps? What's your usage like?
Per Day Usage
Phone calls
Music
Internet browsing
I'm using the Sola and I hate the battery, I have to charge it 1-2 times per day. I use it for 1 hour of browsing, 1 hour of music, 5 minutes of calls, lighting texting - then it dies, I hate it. I'm considering the Go or J. The J has poor CPU/RAM but far bigger battery vs the Go.

The GO has a *****n nice battery life I'm using a Sola and get round 16hours. My friend got a GO and his battery was after 9 hours from 100 on 80%!!
After 9 hours, your friend's Go went from 100 to 80%? That's not bad at all! Does he/she leave the internet on? That seems to be a huge battery killer but I need it. If the Go could last 2 days I'd buy it now...
I bought my XGO two weeks ago, and below is my battery life and its usage (sorry no screenshots)
Battery Life:
100% to 15% lasted around 45-50 hours
2 to 3 hours screen on time
Usage:
Exchange push sync (email, calendar)
Gmail push sync (email, calendar, contact)
Outlook.com sync every 1 hour (email, calendar, contact)
No Social Network (Facebook, Twitter, etc) sync
light web browsing of 15 minutes daily
Power Saver implemented:
Installed BitDefender PowerTuneup (disable all network connectivity from 1 - 6am daily, except only connected to basic phone network)
Restricted all background 3G data except for Exchange, and Google native services
Location, GPS, Bluetooth turned off 99.5% of time.
Screen Auto 55%
Battery life is almost the same as my Galaxy Nexus, but my Galaxy Nexus can never get more than 2 hours screen on time even with 2000mAh battery, I guess maybe the screen used up too much power... Battery life for Go is pretty good in my opinion, would be super if it comes with 1600-1700 mAh battery...

Yes he did The whole day, his mobile Internet is activated and he has a screen on time of round 75%!!
I get about 4-5 hours nonstop browsing with brightness at about 30%, wifi and autosync on.
If wifi is off, I lose 2-3% while I sleep. That's about 7-8 hrs of sleep.
I keep data on and forced 3g during work. Signal is poor at my desk so with constant use I end up with about 30-40% after 7 hours if I didn't bring my charger.
Battery mileage really depends on how it's used and what's installed and what's running and how bright the screen is.
The bottom line is that this phone lasts one work day with me without having to charge.

My experience from Go's battery is that if you do not have 3G on is good. Otherwise it is draining too fast. I get 1-2 days battery life depending on the use. Usage is mainly phone calls and texting and a bit of browsing and checking fora through tapatalk or xda apps. For forum reading I use 2g/edge so to not drain my battery. Brightness is at auto with 100% max level. In general I don't think its battery cab endure a whole day of heavy use.. Screen usually drains 65-70% of battery according to statistics.

Xperia GO Battery Life
I got this phone two weeks ago after having a water ingress failure on my Motorola Defy.. what a shame, but now I'm happy. This ST27a is a great phone, I am not a phone movie watcher or gamer, so CPU and RAM are more than adequate for myself. Great look, light weight, perfect size AND waterproof (angels singing)... I ordered it unlocked and it came with ICS pre-loaded (4.0.4), at first it was such a huge disappointment as for the battery life, it was draining very very quickly almost needing two charges at day, there was a system update available but I was lazy enough to not install the Sony thing on my PC, then I finally got the weekend time and updated it (to the 6.1.1.B.1.10, KERNEL VERSION 3.0.8+) IT SOLVED MY BATTERY ISSUES!!!
The phone has a more than sufficient battery life, I do surf web every time during the day, have updates every 30 minutes for Gmail, Facebook, weather, news, everything, and it lasts from 8.00am at 100% to next 11.00am to 14% (which the preset low batt alarm sounds). Only thing I do is switch data off during night that's it. Screen brightness while in the office is at minimum but you can easily read it very clearly. I do take a lot of pictures for my work and some videos and still get that battery life. The phone is OK, just take care of which software version you have installed. I am sure that if I would turn the data off and activate it only while the screen is on, the batt would last at least two days (I will make this test and see what happens).... cheers.

With data, bluetooth and wifi off, I only lose about 1-2% overnight.
With Data on, this thing drains about 1% every 2 minute or so.

Crazy Battery Life on 920

The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.

after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.

Degraded battery ?

Hello
I've bought a One X+ second hand and the guy that sold it to me said it was only 2 months old. I have reasons to believe he was telling lies.
Here are some screenshots from Battery Stats Plus:

I've only used the GPS for like 3-4 minutes (not using google maps) and Google Maps separately (no GPS) for 3-4 minutes total. I don't know why it shows a big % on battery usage from Maps. Also the battery history from Settings said that I had the GPS on all the time even thought it was turned off.
DS Battery Saver was also turned on (Gentle profile) so it would go to sleep when screen is off.
I generally can barely manage over 24 hours on a single charge (normal usage, 2 hours of on screen time).
When it's sleeping (all communications turned off) i'm usually losing 1% of battery every 45 minutes. Another thing: the last 15% of battery drains in 3-4 minutes when using the phone (browsing, etc).
Is my batery ok ? I think the device's older than 2 months when I bought it because my older Sensation XE could easily manage over 1d6h normal usage even after 1 year.

I am not really harmed with mine's battery life, ofcourse I would prefer having better battery. But overall I can survive 15 hours with 2 hours onscreen surfing the web /xda
And about 40 minutes hardcore gaming (fifa 14 and other games)
With about 30 minutes call time.
But keep in mind during screen off I have my connections off.
P.S if you can root, you should definetly use "Greenify". It's the perfect battery and usage saver.
My day as you see is short but during the night (around 8pm) when I sit on the phone for 6 hours of intensive gaming and surfing the web, I usually have to make 1 and a half charge

Hmm....well ok. Before buying the phone I read the battery test on gsmarena and was pretty much pleased with their results. But they tested it on android 4.1 whereas I have 4.2.2
Well if you really want to test battery and know if it's bad or not , charge till 100% then remove the plug and keep it sleeping till it runs out of battery. Or check on it after 3 days to see the percentage .
After doing so, surf the web browser till the battery runs out from 100%
Then charge again till 100% and do some hardcore gaming till it runs out.
The final test, charge till 100% then use the phone with your normal daily use.
If you do not like the battery performance you can switch phones.
