Galaxy S3 no battery life. Confusing me - Galaxy S III Q&A, Help & Troubleshooting

Hi there,
My friend has an S3, and we are baffled to the problem.
Basically the phone has 3-4 hrs battery life from a full charge. We tried a hard reset, new battery, app killers, disabling apps, virus scans, adware scans, etc. No avail. It just eats battery on or off.
The phone does run very hot, just sitting there the temperature is up around 50°c. The SD card also won't register.
Has the handset developed a fault?

stock rom ?
use better battery stat monitor wake lock and disable service that wake your phone

Yes stock Rom. Phone hasn't been molested.
As said even at rest, just sitting, the bottom of the phone is hot.

I think that normal battery stat if you always connect 3g internet. Try to use 2g when screen off using tasker profile, monitor wake lock then disable it, disable location service and enable power saving mode. It should reduce power consumption.

Well I had an S3 before I got a Note 3. I've set his phone up exactly as I have both of these set up. I could go a day or 2 on the S3 without needing a charge, if I wasn't using it.
Even on the note, I'm always in a 4G signal, and always have apps running in the background, and diddle on my phone for a fair bit during the day.... I still easily have over 50% battery come home time.
His S3, even left with data network deactivated, and not using the phone at all, will be flat within 6hrs.

Time for a new battery , if thats won't help . paint it blue and throw it to deep waters . Good Luck .

Some users, including myself struggle with a massive battery drain after the latest Google Play Services update. It might be that perhaps?

Not sure if it is that,but with stock ROMs I feel kind of a battery drain,while with aosp it's amazing. Google services updated right when I went back to stock,though. So,not sure.

Use trickster mod to force the phone to go in a deep sleep and handle the wake locks

Check this..
1. Use LTE Only When Needed
Never use LTE if you're not using it at all and select 3G instead. 4G/LTE features high-speed mobile data connection but eats a lot on the battery more than you think than 3G.
2. Selective Features
Features are amazing and may actually help you every day but not all of them are good for the battery. Keep those features you use at all times and turn off others which are not needed on every day activities.
3. Wireless Connectivity
Aside from mobile data, watch out for other wireless radios such as Wi-Fi, Bluetooth and NFC which consumes power and you must turn them off whenever not in use.
4. Preferred Internet Connection
Whenever there is an available and decent Internet connection via Wi-Fi, use it instead of mobile data to preserve power on your phone.
5. Display Screen
Around 50 per cent of power consumption is allocated on the screen which means you need to manually set the brightness level comfortable to you, minimise screen timeout and use static yet dark wallpapers to save energy on the display.
6. Location Services
GPS can kill your battery life and set only certain apps allowed to use location services - those which requires it.
7. Apps and Widgets
Widgets are good display designs on the home screen but only a few helps your battery. Remove widgets you're not using anymore and uninstall the app altogether. In addition, be careful with certain apps which are poorly written that may eat away battery faster or damage system files on the worst part.
8. Don't Forget This!
Samsung installed a non-removable Power Saver on your Galaxy S3 and you should use it as much as needed. Whenever you are not using any Internet connection or high tasking services, activate the Power Saver from the notifications shade to manage battery life better.
9. Colour Profile
Galaxy S3 features screen mode and you should use customise the profile to help save power consumption on the Super AMOLED display screen.
10. Refresh Regularly
It is recommended to restart your phone once a day to refresh the entire system after an entire day of full work just like a computer. It will also help the memory to perform better after a reboot.
11. Factory Reset
In worst case scenario of apps damaging the system, you'll need to reset the smartphone. It will restore the default apps and remove all other culprits which may have caused the battery last shorter and poor performance on the phone.
12. Drain the Battery
Certain times require battery drain similar with laptops and notebooks to enabling healthy charging cycle. Usually, battery draining a device once a month then getting a full charge for about four hours keep cycles healthy than those units without recharging cycle.
13. Avoid High Temperature
Avoid leaving the phone inside your car or putting it on a surface with direct sunlight to prevent damaging its battery. High temperature will damage the battery pack leading to poor performance. However, extreme cold can also affect the device leading to moisture damage.
14. Root Access
Rooting will void the warranty but if it's already gone, why not do it anyway. Root access will enable you to control various aspect on the battery and processor to improve power management.
15. Custom ROMs
Samsung Galaxy S apps and TouchWiz UI consume high amount of battery which makes other Galaxy S3 users to resort on custom ROMs. Custom ROMs always feature better power management, CPU tweaking and larger memory compared to stock ROM and if you want longer battery life, get a custom ROM.

If you want an app which will schedule your connectivity like WiFi, 3G, Packet Data and GPS etc then you could use it, but if you think it saves juice and produce good battery backup then NO, it drains more than it saves, I know some users here who were fan of JD but ultimately stopped using it for battery saving. Now it's your turn to think on which boat you are.
Regards.
I'm using Juice Defender Ultimate and using Advanced profile. My last recharge lasted for 38 hours and still I had 15% battery left...and I'm on Lite'ning Rom 6.1...I'm not an expert...but seems like it's working.
For me its working great. I removed the blotwares from my phone (Hubs and all other useless things) and JD is working fine. I'm using the ultimate edition and very happy with it.
@ithehappy I guess we will just have to agree to disagree on everything bro
I too use Jd Ultimate, other than sometimes it stops working, it works great. I use it to overclock and control my cpu speed too. (with ninphetime kernel)
Sent from my GT-I9100 using Tapatalk
I don't like this kind of apps. I think Android does a good job with battery saving if everything matches well together.
Therefore search your
personal best modem.
personal best kernel.
personal best rom.
Add some smart tweaks.
And tada you will have a good battery life.
I have been using JD Ultimate for quite while with my old Desire & now my SGS2. On the SGS2 it displayed a number of problems:
- sometimes it lost its configuration data
- other times it would stop working completely
- the location feature where wifi was only enabled in the vicinity of known networks didn't work at all
- the feature where wifi was supposed to stay enabled when certain apps are a running didn't work
Just for fun I uninstalled JD a few days ago and my battery life seems quite a bit better than before. It took a few days to get into the habit of turning everything on and off manually. Mobile network and wifi are only turned on when needed.
Yes. I think it works. It's a good placebo anyways.
I use Tasker to automatically shut off the radio's when I'm sleeping. Works more reliably than JD's patchy on+off routine. Of course, you could just turn the phone right off as well.
I think JD does work, but I'm not sure if it's work the resulting inconsistant connectivity.
Removing bloatware (use CpuSPY and the Running services in the Applications settings to see what's sitting in the background) helps a LOT. Removing all of the useless Samsung UNA rubbish is a good start.
I've undervolted+underclocked mine to 800mhz, I can't notice any difference in usage, I'm not sure if it helps much or not, but I tend to get somewhere between 2%-3% per hour idle drain (the phone is in deep sleep so underclocking/volting is fairly irrelevant to this figure).
Whatever, the hardcore anti battery saving people might say it won't work. But I clearly see a huge improvement.
Running JD Ultimate saves me a lot of power. I easily get 2 days of usage (very personal, but it works for me - I use a lot of Spotify all day.. high volume )
It just works.. period. Turning off data and Wifi over time, included with other automated processes can't do much else than save battery.
Android doesn't need an app manager.
I voided my warranty and your mum.
I have it installed but only turn it on when needed. Ie if I'm out for a long day and my battery is getting low I'll turn it on. But otherwise I don't use it. I think it died help a little. But also there is the inbuilt power saving options in this phone that seem to work well too.
I use to use the app, and it did work for me, but I am no longer using it as I am now always close to a charger. when I need to conserve power (which is very rare) I turn off all data connections as I have found that this is my biggest source of battery drain.
The connection itself and apps updating in the background or when the phone is asleep, to add insult to injury, my data connection is very slow, causing the apps to keep the phone awake for a longer period to pull all the updates

2 day users - Optimal battery settings?

Wanted to know from those getting 2 days out of the mini pro, what are your systems settings to make this possible.
1: I have my screen to less than 50%, can only still manage a day.
2: Do you guys turn off 3G HDSPA?
3: Does wifi use more or less battery than HDSPA?
4: Any of you using a blue tooth headset?
5: Any specific apps to kill?
6: Any special battery conditioning done? If so steps?
7: Do you guys have exchange e-mail on? push or pull?
The battery meter is showing more than 50% going to the screen.
Good that it seems I don't have an rouge apps and the wireless doesn't seem to take up too much battery, but a let down that I can't get more than a days worth of battery.
Found some decent battery recommendations here

Why are you trying to make your battery last 2 days? Do you not have access to a charger everynight?
Also I do not recommend you 'kill' any apps, due to the nature of Android. If you 'kill' an app, it's very likely it will just start up again, using more CPU cycles than if you just left it idle. This is especially an issue if you are using an auto-killer.

1. set 40%, add widget at front wall for fast switching (to 80%)
2. turn off mobile network (data), add widget at front wall for fast switching (to enable)
3. -
4. no
5. using system panel lite to clean and root uninstaller to remove apk at system app (currently memory at 230M-240M)
6. restart phone 3 time per day, use 1800mAh, charge phone when >5% energy, to 100% (45minutes), turn off while charging is more better.
7. no - exchange e-mail running at background processor (any unwanted background I will kill or remove; currently only 3 apps still running)
use dark theme/wallpaper for energy efficient (low brightness) and use earphone to listen music

I'm not sure what value this message is supposed to provide. I've seen folks post that they can get 2 days or better out of the phone, if so what's wrong with wanting to do the same?
Also note that there are times when it's inconvenient to charge and I'd like to defer charging. I'm pretty much out of juice by end of day the work day, but would like to have a few more hours of battery left, having the phone on the charger all the time isn't always convenient.

I understand if your phone is starting to go flat then you might want to start conserving battery, but if you have the ability to charge it then why not?
I agree with r33p. Using a task killer is possibly one of the worst things you can do to try and save battery. Using less memory does not save battery at all.
Also im not sure if this is true, but using a dark theme does not save battery as the backlight is still on, but screen is just 'hiding' it to create the black you see. So if anything it uses more battery.
I tend to keep a widget on my home screen to turn off data, wifi, and bluetooth. I turn them on when I need them, turn the off the rest of the time. As long as you aren't doing heavy internet browsing on your phone, you should be able to get two days use out of it.
Hopefully we'll get some custom roms for these things so I can justify rooting my phone. Then I'll uninstall all of the stock apps I don't want, both to clean up my app screen and to hopefully stop some of those background processes I don't need.

I must agree. Using a dark background does not save battery. That only works for oled or amoled based screen like the galaxy s series. Also they're right, don't use a task killer. Terminating apps just consumes more battery.

i can last 1,5 day without charging.
if i dont do anything special besides reading mail and answering a few whatsapp messages i do about 3-4% an hour. if i dont do anything at all, like at night, it uses 1-2% an hour.
1.screen is 35%
2.i have 3g on. sometimes i put it on 2g only
3. i dont know but i turn off wifi en bluetooth whenever i dont need it.
4. i use bluetooth in my car tot connect my phone with my car. unfortunately this uses a lot of battery by being just connected.
5. i kill the popgames, this uses a lot of battery
6. most times i let the battery go empty and only then start charging with the powerconnector, not through usb with a computer.
7. i dont have exchange but imap push email and another account pop3 which connects once every hour. i use the app k9mail
last weekend i did 2,5 day but i was abroad and didnt have roaming data and turned off wifi en bluetooth.
i did 1% a hour except when i was driving and connected my phone to my car.
but still 2,5 day

Does 2g only save battery over wifi and 3g? If so, is it sufficient for e-mail?
Mike
I normally put all of my most used widgets on the front page for quick access
3g or wifi pref. 2g is painfully slow.
Yea and forget appkillers,delete the apks or freeze the unwanted services.
The tricky part - what (not) to delete.

You need root to do that, however.

yes 2g saves battery
i was told that because of the continues switchting between G, 3G and H the battery consumes a lot of energy.
when you put it on 3g only or 2g only it saves battery.
becasue i dont have 3g everywhere i go i put it on 2g so that i can make calls everywhere i am.
if i need to do some things on the internet i switch it back to 3g.
2g is enough to recieve mail and whatsapp messages.
my mail wont come in as fast as wifi or 3g but that doesnt matter to me.

How do you set it to H only? Is this via WCDMA only?
I'd love to drop the bloatware, but want a clean root option that won't affect functionality.
Mike
I have about 2 days. Currently I'm on 82% 12h since charge. My experience:
1. I keep 3G switched off most of the time when I'm outside. Only if I really need the speed for uploading a photo or update an app.
2. I keep Wifi running all the time at home.
3. I have disabled Location&Security both Use network and GPS. These seems to drain battery even if maps and latitude is disabled.
4. In the carrier settings I have disabled automatic mode and going for manual mode and selected my carrier.
5. I always use the back button on any app until I reach the home screen before locking.
My idle drain is about 1.5-2%/h when I'm at home with wifi. Outside with 2G it's draining a bit more and with 3G it uses insanely much battery.
I have lot of push services running (fb/g+/twitter-notifications, Whatsapp and gmail + an Exchange account)
I have also noticed that the battery calibration is a bit flaky. From time to time I run the phone until it dies (sometimes at 8-10% but sometimes at 30%). Then I'm unplugging the battery for a minute, plug it back and charge and it have calibrated and doesn't die at 30%.
Another thing I have noticed is that I can't get more than 4172mV charge. The battery should be able to charge to 4200mV.
Two good apps for monitoring battery usage is BetterBatteryStats and Battery Monitor Widget (which is more than just a widget)
do you guys charge till it reaches 100% or just till it turns green?

thats one other discovery I have made.
when the phone says 100% it's actually still charging (can be seen that there is a charge indicator at the battery and also can be seen from Battery Monitor Widget)
Another thing is that when it has reached 100% it starts to drain battery until it reaches 95% then it starts to charge again. (nothing uncommon with that) but the phone still shows 100% so sometimes when it's unplugged it can actually be at 95% (but starts to countdown from 100%).
Battery Monitor Widget can alert when it's actually fully charged with a notification.

Auto brightness, turn it on. NFC, Bluetooth turn it off. I always suggest that users turn on extended standby mode but some people want their whatsapp or email to come through instantly all the time which I can understand but it's a real life saver for me, I personally don't have a massive issue with my battery, lasts a whole day, sometimes less if I use the phone heavily.

I think there is also a problem with reading the actual battery level (hopefully not hardware). The other day mine dropped from 15% to 0% in 10 seconds. This has happened a few times before when the battery gets around that level.

You could use clockwork recovery to erase the battery stats as well. I don't think you need root for it.
You charge to 100%, reboot into recovery erase battery stats, unplug and boot normal. After that you let it drain on its own until dead.
I've read that sometimes it worked after the second calibration or something but i believe it might be user error.
I erase the stats every time I flash a new rom. ...
I am now on 2.3.7. ... Maybe is better

Battery stats doesn't do anything: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.

I would advise you to update your phone to the latest firmware, it has better battery management... If you are rooted, you can try custom kernel like ThP or Sliding_XP and custom Rom based on stock... I used to get only 10-12 hours of battery life in 2.3.7 before rooting.. The steps I took to improve battery life are:
1) Root the phone, add init.d and build.prop tweaks or install a Rom that has tweaks like Brain_ICS or XPT's Vision Roms.
2) Use any custom kernel based on stock that are tweaked to give better performance and battery life, along with above Roms
3) Switch off WiFi, Bluetooth, NFC when not in use. Or better, use NFC tags to switch settings (like WiFi on only at home, Bluetooth on only in car)
4) Keep the brightness to the minimum setting when indoors and keep it in auto brightness when outdoors.
5) I live in an area which has better 2g coverage. In network settings, if you set the network mode to select only gsm, battery life vastly improves as there is no searching and switching for a 3g connection. Also I find that staying in 2g gives better network clarity. I shift to 3g when I require high speed browsing only.
6) I usually keep data connected with auto sync on and extended standby mode on. If you switch off extended standby off, you can last through the day but only if you reduce the amount of apps syncing and the polling time of each app. In my case, I have switched off syncing for Twitter, facebook, Google+ etc and sync only for Google contacts, calender and Gmail.
7) I also have automated the phone to switch to airplane mode from midnight to early morning.
By the time I get home from work, I have at least 40% battery remaining. On the whole, I get 22hours on average and I have got 1day 12 hours maximum from my Xperia P. And happy with my choice.

Forgot two things:
I keep all location services switched off and turn it on only when required. This prevents the Map app from unnecessarily polling for location and helps save battery.
And sorry for such a long post. There won't be a tldr.

Just had this weird experience, battery was on 1 percent then I rebooted my phone using power button and volume up, then my battery shot up to 28 percent

that was android normal problem....thats why developer making phone by using high capacity battery (motorola razr maxx) . By using 3000mAh battery also just give certain phone for 2 days (using galaxy note 2). Android jelly bean suck battery juice faster because of its f***** project butter (uses cpu and gpu at the same time). Now phone developer starts frustrated on android...hehe (from my speculation)
Android problem how?
Almost all smartphones last about 1 day. Don't blame the Operating System it's the same battery life in all smartphones. Blame the battery technology.

Battery drain during standby/sleep

Has anyone noticed significant battery drain whilst the screen is off, my phone loses around 1-3 % every hour even when there are no programs running. I have monitored the running apps and uninstalled many that were running in the background. Does this mean that the 5th core is not activating or am I doing something wrong, google now, wifi, bluetooth, 3g, etc are all turned off, If anyone experiences similar issues or knows a solution please post, other than that the battery life on this device is actually pretty good despite all the people stating how horrible and unsatisfactory it may be.
I believe someone mentioned that the WiFi is the cause of the drain while the phone is on, is your WiFi on while it's sleeping?

Google Now may cause battery drain while on standby, I think. You might want to install Better Battery Stats so you'll know what's eating up your battery while the phone is in sleep mode.
My WiFi, Bluetooth and 3g are all turned off and Google now has been disabled, don't know what is causing the drain but the people over at the original one X forum are sating that standby drain is higher as of the jb update which I find odd seeing that the battery life is better screen on.
Turn off auto sync & just enable it when you need to, or use an app that will enable it for you after a certain time period.

Nah I can go a day and half on stand by with little use. I have 30+ apps installed and mods to firmware plus nik3r's custom elite kernel.
I'd say its one of your obscure apps you still have I stalled. Do a factory reset on your phone and install each app one at a time each hr monitoring the drain till you find the culprit.
Install nik3r's kernel.

1) go to Facebook app, disable chat, disable location... disable auto updates/notifications too if you can. This crap (especially the latest version) can take 20% of your battery life easily.
2) go to Google Maps settings, disable all the tracking/reporting options out there (up to 15% battery life without ever even starting the map app)
3) install EliteKernel and use power saving if you need that extra standby juice (it actually saves power in my flavor compared to the stock version)
There - fixed.
Wifi is not the issue, I get better life on 100% wifi than on data connection. It's the apps that actually use tha data.
Thanks guys much better now!
turn off this, do not use that.....
if is this the solution what is this? a phone or what?
only hope a room that end with this battery drain, is not normal that my wife S3, the same battery (2100mA) like hox+ has more hours, and not only 1 or 2, 6 hours more battery life, both without use.... in the same place, we did it as a test and..... that´s the Q, why? we have the same apps installed, and we have the same on, wifi, data, gps, blutooth..... the same conditions

are News widgets draining battery life?

Also is keeping mobile data on, ok for battery life?
News and weather widgets regularly wake your mobile from sleep to check for updates. So, yes, they drain battery.
Also, keeping your data on continuously will drain battery.

All widgets that require network access (WiFi or cell) will wake the device periodically. Since you have a Smartphone and want to enjoy such features, just ensure you set the refresh time to an hour or so to limit wakes but retain their usefulness.
Your phone is very able to manage network access, so you would want to leave WiFi or GSM enabled. Otherwise, what's the point of a smartphone?
Unless you have a rogue app that keeps waking the phone for some reason, enjoy the features of your phone and don't become OCD about battery life like some on here...

Best advice, some people spend too much time trying to bleed that extra 5 minutes out of their phone and hardly enjoy the fruits lol
As long as any apps don't use mobile data, it will not drain any battery ? Even it is turned one?Is it same for the GPS? is that right??
what is your source?
thanks
