[Q] immediate battery drain - T-Mobile Samsung Galaxy S II SGH-T989

The battery on my phone was somewhere above 80% when I turned on the GPS and used google maps to go somewhere. 10 minutes into the drive my phone shutdown instantly, no warning no notice of battery being low. After making it to my destination I came immediately home to for answers on this forum. I had thought that my phone crashed and wouldn't power back on. Well it didn't crash, it was out of power. Has anyone else seen this before 10minute battery drain with GPS turned on using maps. I am running jug5.0 with no other tweaking going on.

GPS is a big battery drainer. My battery wouldn't drain that fast, but it is a power guzzler. It would be great if you invest in a car charger for your phone. I remember I was using my GPS on spring break to get here and there and when I had it charging in the car while using the GPS, the battery remained at that only percentage for that whole 2 hour ride.

How-To: A possible solution to battery life

So several people have started to notice that "AudioOut_1" wake lock might be polling our batteries unwillingly on our part. So I decided to go out and disable everything that could make sound except for the ringtones and notifications themselves since we all have to have that. This is what I came across...
---------------------------------------------------------------------------
Settings > Sound
Uncheck "Touch sounds"
Uncheck "Screen lock sound"
Profit.
---------------------------------------------------------------------------
Just went an hour without losing 1% battery after I did this.
Some people are claiming they only are losing 1% or less per hour now, just leaving the phone sitting not doing anything. So this may be the temporary fix for the phone being awake when it doesn't need to be.

I tend to turn those off anyway, just hadn't gotten around to it yet. I went ahead and did it now, along with vibrate on keypress. We'll see how it works!

Seems to be 50/50 on this
Ive had those off and I am actually going to run my phone in vibrate only mode for a while and see what results from that.
this has little to no effect on battery life. Look at your Android OS battery consumption before, and after. It will be the same
Biggest solution I've found for battery life is disabling my GPS when I don't need it, and going to CDMA rather than LTE/CDMA. They're still there for me when I want them, but most of the time I don't need them.
Right now I've had the phone off the charger for 4 hours where it was topped off; I'm at 91% now, with moderate use (Google Currents for half an hour, about another 20 minutes total screen-on time doing other dinky things, three texts)
First of all, disabling GPS will have absolutely no affect on your battery life. The GPS is only enabled when an app calls for it, if you don't have Google Maps open, then your GPS won't be engaged.
And turning off the sounds will have little to no affect, it's the vibrating that kills your battery more. Turn off haptic feedback, turn off vibrating notifications, turn off vibrate on key press for the keyboard.
Oh, and staying connected to wifi is much easier on the battery than using data. On wifi your phone doesn't have to keep polling the cell towers for signal

Turning off GPS works for me because I often use social apps (e.g. Facebook) that engage GPS for their 'check-in' features. It may be a minor thing, but having turned the GPS off, I've seen real results. *shrug*
Also, maybe a gimme for you smarties, but I disabled VZ Backup Assistant.

Yes what you are saying has made sense in the past for Froyo and GB but we are having some sort of unknown wake lock and this seems to be the biggest one. Ever since I have disabled both of those features my AudioOut_1 wake lock hasn't awakened the phone ONE TIME.

I had a custom rom with dreadful battery switched back to the latest stock and have noticed the following: When you have good signal the screen on and awake seem to match up, i only lost 30% in TWO DAYS! then suddenly when i went out to the country side today i lost the remaining 70% in only a few hours seems that when the phone has low signal is is almost ALWAYS awake. I understand that in lower signal areas the phone tries harder to get signal but surly it shouldn't be awake like 90% of the time!
my top 1 was some sort of googlephotos sync service. i might turn off instant upload with google+.
that audioOut_1 was at like 1.2%, turned off these 2 settings before i unplugged from charger

Yep that is another major contributing factor to terrible battery life. My phone will drain VERY slowly in good signal and die rapidly in bad signal.

My G2 will shut itself off - any suggestions?

I'm looking for any ideas for the problem I'm having on my G2. I'm afraid it's a hardware problem and not much I can do about it.
I started having problems after upgrading from CM 7.1 to 7.2, but I don't think it was related to the upgrade. I started having battery draining problems, the phone took forever to get fully charged, and car mode would automatically start sometimes when plugging up or unplugging the charger. I cleaned the usb port with alcohol (with battery removed), let dry, and restarted. Now I don't have the car mode problem and the battery problem is somewhat better.
My problem now is that the phone will just die when I'm using it. Usually when I'm using the browser. I'll be scrolling on a page and the phone will just turn itself off. Like the battery died. I can turn the phone back on and it will start up, get all the way started back up, but while it is still loading the home screen widgets, it will go off again. I can repeat this several times. The only way to recover is to plug in the charger. I don't have to hit the power button again, just plugging in the charger will start up recovery mode automatically, I'll choose reboot and the phone will start normally then and stay on.
The phone never dies when I'm not using it. I'll carry it all day, making phone calls on and off, and it'll stay on with no problem. Mostly, I only have the problem when using the browser. Also had the problem while using my newsreader. Once during playing a game. But if I start up browsing the internet, it doesn't take long before it will turn itself off. A matter of a couple of minutes. I don't have the problem with reading emails with K9. Don't have a problem in downloading from the internet such as podcasts. Don't have a problem in sending text messages. Don't recall it shutting down while using the Facebook app. After putting up with this for a week, some troubleshooting and observations.
I never have this problem if the charger is plugged in. Only when it is running fully from the battery.
I've tried swapping to a different battery.
Turned down the overclocking with no difference.
I've changed to other recoveries, CM 7.2, CM 7.1, a CM 7.1 that I was running in May. No difference.
I've swapped memory cards.
I've reset battery stats.
No difference if running on wifi or just data.
Clearing caches made no difference.
So, I start thinking it must be a hardware problem, but then why does it only crop up when internet browsing. Must be power related since plugging in the charger makes it go away, but why does it not have a problem with using the phone in other ways?
Any suggestions on what I could try?
You could try to see if there is too much voltage drop when you start something power-hungry. Use a battery voltage logger and post the results. Start logging, let the phoneidle for a minute and then start browsing. Even if the phone shut off, the log should still be there after rebooting.
Thanks for the idea. I can't locate a logger that looks like it would work. It would have to capture a quick drop in voltage that is momentary. This problem happens even on a full battery and when the phone come back on (either momentarily or after a recovery reboot) the battery level is unchanged.
You might try as well an other way: first idle, then gradually step up to a more power hungry app to see when the problem actually happens. I have no other ideas...
Make sure that you dont have any contact with the battery and the door.
Normally batteries are covered with an aluminum wrap, and can cause short-cuts with the phone itself.
I searched it for a while with the galilio batteries.
You can try to put some saranhwrap around the battery.
I have the same problem with two different batteries. But I'm ready to try that too.
Battery graph
So here's a graph of my battery status. Long time to charge to 100%. Discharges pretty rapidly. Each downturn ends in the phone turning itself off. Notice that at 7:30 today, it turned itself off, I did a recovery reboot, then noticed it wasn't charging very well (green line turns to blue but doesn't increase), then I did a manual reboot and when the phone restarted, it showed the battery was at 100% charge (from about 60% before the reboot).
What do you think - hardware or software?

Well, I just took the cover off for awhile and tried it. Played crosswords (Shortz) for awhile with no problems. Started my newsreader (Newsrob) and it shut itself off in about 15 seconds. So, no short to the battery cover.
Same thing is happening to me. I use poweramp or the browser and the G2 just shuts off. Then I restart it and it tells me that the battery is low. Once I shut it down and reboot in recovery and wipe the battery cache it's back to it's normal battery level. I disabled data and set my phone for 2G networks only and it didn't shut off after. I'm assuming this is a wireless issue? I'm running mimicry 1.3.0 on my G2.
Had the same problem. Swapped out batteries and problem gone.

Did you swap the battery and immediately have no further problems? I tried swapping my battery already and still have the same problem.

[Q] Rapid Battery Life depletion during sleep

Hey XDA friends. I got the Verizon HTC One a few weeks ago and battery life started out fantastic. When I put away to go to sleep it only lost 7% all night with GPS on and wifi on and all that and I was astonished. However as time went on I found those results kept getting worse and worse until I was draining 30% in a night. I went and uninstalled battery guru and now I only drain 12% a night. Some nights however I still lose 20% in a night with sleep mode on. How do I check what keeps waking my phone up and draining my battery. I'm afraid this will affect my phone's battery in the long run. I will start disabling GPS at night but I wish I still had that 7% in a night. How do I check what is messing with my phone???

go to settings/power/usage. this will tell you which app is using the most of you battery. also you should never have gps on while youre sleeping. you might also want to turn off auto-sync and then re-enable it after you wake up. you can create a widget to do just that. if you need help with that, just let me know.

Do you use blinkfeed, that will kill your battery pretty fast. Even if you don't think you are using it, go check and see if it's syncing anything in the settings. I thought mine was turned off, but then I logged into facebook (turned sync off in facebook), later I found that blinkfeed was syncing it anyway w/out my knowledge.

Really, 1% per hour on standby with cellular radios on is pretty acceptable. Depending on signal strength, the radio could be pulling that just to maintain a connection to the tower.
Thanks everyone!
With GPS off, Sleep mode on, and NO BATTERY HELPER APPS (Battery guru was diminishing my battery life) I got a record breaking (for me) 4% loss in battery life during my 8 hour night's sleep, not bad if I do say so myself, after that my battery has been a lot better. I wish Verizon would give us HTC's battery saving software back but let's not ask too much of Verizon or they might give us timely updates.

Hey..I had the same problem so...first download wakelock detector from play store..after installing jus use your phone like as usual..after 4 to 5 hrs or right before you charge your phone, open the wakelock app and check what's waking up your phone during sleep..for everyone it seems the battery is drained by Google services ..the main culprit being the location services.. so switch off the location services in settings..and also in Google maps, go into setting and then into Google location settings and make sure location reporting and location history are disabled, make sure they are unchecked.. that's it..restart the phone..fully charge it and test it out ..and DON'T use any battery saving apps ..and also uninstall wakelocker app after your battery life is back to normal..I'm an average user and I unplug around 9 in da morning and when I come home around 6, I still have 65% left..I don use facebook .. heard even facebook app is major battery drainer....you jus have to tweak and play with settings till you find your desired battery life expectancy cos everyone uses their phone differently..and we all have different apps so the main thing is to find out what's eating the phone battery most...I'm just pleased with my decision in picking HTC ONE over galaxy S4
similar problem here....google services is killing my battery (relatively). location is part of it, but google hangouts is also going crazy (watchdog alerts me to excessive usage....over 50%, but hangouts was at 100%)
i was spoiled on my g-nex, where i left wifi, bluetooth, and GPS on 24/7 and could easily go 24 hours. now i'm lucky to get 12 (with about 1 hour of screen on time).
I'm hoping things will sort out, device is only about a week old, but google optimized location usage (iirc) such that it isn't supposed to constantly ping and kill battery. we shall see, i guess.
I'm not sure what the problem could be but I'm just gonna say that yesterday I got around 18 hours of battery life with over 5 hours screen on time which I consider awesome battery life.
I'm stock, so it's definitely possible to get good battery life.
10 percent overnight? Thats not that great but not horrible. My dna is running carbon (android 4.3) I use tasker to turn off autosync and data/wifi and put it on silent at whatever set time I make it. My phone drains about 5 percent max overnight, usually a lot less.

you can turn off updates in facebook and its not bad, but yeah if you have autoupdate on, it can kill the battery.
as far as the OP, I don't get why you don't charge you phone while you are sleeping. Seems like the perfect time.
Turning GPS off shouldn't affect your battery life. If you're not using your phone, the phone isn't going to use the GPS for anything. So it shouldn't be using your battery. The culprit is usually an app that is wakelocking your phone. So you need to find which app it is that constantly wakes your phone from deep sleep. Turning off autosync would help a bit if you are really paranoid. The big thing that hurts our battery when the screen is off, is the LTE radio, but most people are connected to WiFi when they sleep so it's not a big deal.
Just an FYI, turning off GPS has been ineffective since 2.2 Froyo. When Gingerbread 2.3 was released like 2+ years ago, it allowed for the GPS to only be used when an app called for it to be used. Otherwise GPS will not do anything unless you pull up an app that calls it to do something.

[Q] Unexpected shutdown when battery is low

Recently my N7(2013) will shut itself down when the battery is low (about 10%) without any warnings, not even the "Shutting Down" dialog that it should show whenever it shuts downs (except for the usual low batt warning when it reaches 15%). After the shutdown, I cant even turn it back on not even the screen, nor the low batt (waiting for charger) screen is showing up until I plug it into a power source the it will show the charging screen and then I can turn it on again.
Its been a few times now, not sure its a hardware or software problem though. It shouldnt shut down when it still has 10% in it right?
Attached is the screenshot of the Battery Usage that shows the battery level shots down to 0% immediately from 10%.
Nexus 7 2013, Stock, Not Rooted
Are you using a battery monitoring program (battery doctor, better battery stats, etc)? If so, look in their settings, to see if they are set to shut down @ 10%...

Nah I don't trust these apps so I don't use them. Moreover I'm did not root it so even if I use them they shouldnt have the permission to shut it down
Simple fix
It is an issue I have suffered with a couple of times and it appears we are not alone. It seems that the battery calibration is out of whack. When you charge your nexus up does it stay at 100% for quite a while? I
tried factory data resets amongst other things and nothing worked. I stumbled across a thread with a really simple fix. Turn your tablet off for 2 hours. Then turn it on again. Mine miraculously lost 26% of battery in that time (from 100% where it had been for 8 hours down to 74%). Then it started to use the battery at a normal rate. Working fine now.

[Q] My Sprint S6 get's terrible battery life

Now.. I'm on my phone a lot normally. I text, and use FB messenger, and a lot of Google Now. Because my phone battery dies so quickly, it sits plugged in a lot, and I don't use it nearly as much as I'd like to.
If I am using my phone a lot, I can take my phone from 100% to 15% 3 times in a day.
I factory reset recently, and just let my phone sit with nothing but Google Messenger and Facebook. It still dies from a full battery in ~4-5 hours, without me touching it. Thing is, all the battery stats show less than 5% usage. And there's no crazy crap like games, etc running. I can't figure out what's eating the battery.
I just put the phone in Airplane mode, and enabled Wifi. I'm getting all my emails, fb messages, gmail, google voice, so on. Battery only went down 30% in 28 hours. I turned off airplane mode (it's not connected to Sprint at the moment, I took it off the account), and I have an Airave...battery dropped 15% in about 30 minutes. Went back to airplane mode with Wifi on, and back to a really slow drain.
Right now, I'm planning on packing up my phone tomorrow and sending it to Samsung for a battery replacement. Because my standard 2A-5V can charge this phone from 10% to 100% in an hour...which isn't right. Not the original QC2.0 charger.
Update: I turned off airplane mode again, and the phone is steadily losing 10-12% battery an hour.. and there's nothing running. It's sitting face up on my coffee table.
What can I do to stop the battery bleed? It's completely stock, on the latest update from Sprint, with no root.
I got an RMA from Samsung to send it in for a battery replacement.
Attached are screenshots of my battery stats. It just makes no sense. Even after a factory reset, not everything using the battery is reporting to that page. The sharp drops in battery are from when the phone is not in Airplane mode (only wifi on)
I've got the same issue. No better than 7-8 hours of standby time. My cpu will also heat up to 160 degrees while running very basic apps.
Any guesses on what's wrong? What have you tried?
turn off:
mobile networks > Connection optimizer
wifi > always allow scanning
these worked for me. hope helps you too.

Yes this is a battery hog for sure shut off that Connection Optimizer, also I set my screen brightness to auto (little check box after the slider) and I noticed a big difference in battery life, I use to crank up the brightness and battery would drain fast, I been on 2 days now at 79% battery..... also not sure but I shut off notifications everywhere too, I don't need facebook telling me everytime a monkey posts on another monkeys wall every 2 minutes, that helps on battery drain as well.
ditto.
This has gotten much worse since I updated to 0I1 rooted with unikernal v9
Also for some reason now... even though both the connections optimizer and wifi scanning turned 'off'-- wifi still keeps randomly turning itself "on" frequently. That with the incredibly poor battery and overheating is frustrating.
Good for you
I had the smart connection optimizer, and wifi scanning off. I also have the wifi location scanning thing turned off.
None of that helps.
My phone is on it's way back to Samsung right now to have a new battery installed.
At this point, I'm pretty sure it's faulty hardware.
