Hey guys, my nexus out of the blue started to rapidly deplete its battery. My charge will go from 100%-0 within 2 hours with the screen OFF. Yep, a total screen on uptime of about 13 seconds. I hoped the problem was with the battery itself so I bought a replacement 3800mah extended battery and it's still having the same problem, except now it'll drain in about 4 hours with the screen off.
I tried all the things I could find via search, turning off all syncs and settings I could but nothing improved it. Also I've wiped several times, there's no additional apps installed or anything, just stock. The phone seems to charge normally, taking about the same time as when it worked fine to get to 100%.
I'm guessing it's a hardware issue, but I'm out of warranty on the phone. Any of you experience something similar and was able to replace a part manually, or is my phone prettty much a brick.
Also I should add that there is no service currently on the phone since I had to switch it out, It's pretty much on airplane mode w/ mobile network turned off so it's not looking for a signal or lte draining. Another thing is that the drain is pretty consistent, meaning I could be using the phone or have it off the whole time and it's still going to 0% at the same time.

Wondering if anyone else has had any battery issues? I went to sleep last night with about 85% or more battery, and 5.5 hours later my phone was dead....when i plugged it in for like 5 minutes to call my work and tell them i was going to be late...when i got to work my phone said 45% phone idle and 45% cell standby for battery use
none here - took phone off charger about midnight, this morning after alarm rang for the full 10 minutes, it still showed 100%
i've been watching it and am really impressed with battery life - is it possible you've got a program running in the background? - i had Startup Auditor to stop apps in the background but had that from before, on my Vibrant
on the vibrant,running a predominantly black wallpaper, screen brightness at 13%, putting phone in "airplane mode" when i sleep, keeping GPS off, data sync off etc, it'd be down to 17-22% at end of day before going back on charger
this G2, running live wallpaper (thunderstorm), no efficiency moves (ie GPS off, etc), screen brightness at 50%, phone still had 34% last night before going back on the charger - and the battery has not "conditioned" - i noticed on the past 2 phones batteries life got better after the first few weeks of use.
Nothing different than my nexus...and i was thinking maybe it was a game but that should have been killed automatically and i dont think it would say phone standby and cell idle if it was an app would it?
tonite you might try putting the phone in airplane mode when you go to bed, and turn off GPS
see what happens to battery drain overnite - if it diminishes then i'd look at what apps you've installed. there was an article on engadget not too long ago that some researchers had analyzed the 358 most popular apps, and found 30 were reporting data to their "mothership" that had not declared it or asked for permission to report data.
hope that helps
well another weird thing is, that when i bought the phone and brought it home, usually it comes with half battery and thats what it showed but i had to charge it quick with no apps really installed on it yet...Im charging now and will test to see what happens with battery...i just removed off alot of my apps.... to see whats up
I'm getting about 10 hours with regular usage though I wish I knew why Photobucket keeps starting everytime i kill it.
I hope you guys charged the phone fully before you used it first. That can play a big role in battery life.
I got my phone yesterday and haven't done any calibrations yet. I've been playing with it like you normally would if you buy a new smartphone. I took it off the charger around 9pm last night and at 7:32am right now I have about 60% left. So roughly 10.5 hours later and I've only lost about 40%. I'm very impressed by that. My vibrant would have been dead by now, it rarely lasts through the night if its not on the charger.

What's your time with out signal, sounds like the 50% bug to me, google the airplane mode fix, if not you might want to look into a new radio, and you should allways recal your battery after you flash

what do you mean time without signal? and cant flash the build or radio without root(if thats what you meant) im fully charging it now and removed all of my apps...and going to see what happens from there
I've been using mine off and on mostly text, web and speedtests for 4 hours off the charger and my battery is at 91%

Last night my phone was down to like 5% so I plugged it into the charger and kept using it. It was plugged in for maybe 10 minutes when I got another bettery warning that my device was at 14% (the plug had come out). Since I was almost done, I decided to leave it unplugged since the plug gets in the way anyway. Shortly thereafter, I think the Volume+ app caused my phone to crash. It just turned off. When I turned it back on, my battery was reporting 39%! I wondered if it was a fluke, so to test, I switched to 4G from WiFi on, listened to music, and continued to use my device to see if I did indeed have more time with it. It went for another 40 minutes or so before the battery was back down to 5% and I plugged it back in and went to bed.
What gives? I feel like my battery life is exceptionally awful, but I thought I was experiencing the Android OS awake thing, since my awake times do seem to be pretty high, like 50% of my time on battery even though the screen is probably on for less than 25% of my time on battery and I only have google apps set to sync in the background. Last night's mysterious battery increase now leads me to think differently though.
Are my battery stats out of whack? I'm not rooted yet so I can't reset them that I know of. I am planning to tackle it this weekend, though. I was waiting to make sure the phone doesn't have any issues so I didn't have to go through relocking it to return it.
Attempting to attach a screen shot.
Normal Android behavior. I've seen it on every device I've had since the G1
The battery and the OS become mismatched if you restart while charging. The OS will report a "faster drain" when it reality itsvjust trying to match back up with the battery.

after talking to lg and rogers i found a way to fix my battery bug or what ever it was........
Issue: weak battery-very bad battery life-needed to charge twice a day on normal usage. Lg and rogers both said its a hardware issue and need to be replaced......(IT WASNT)
Solution few easy steps should fix it:
1. Let your battery die to 0%. It drives down by 2%. Turn it on, it will let you turn it back on and shots automaticly back down. do it a few times till it shows0%!!
2. Plug it into your charger and let it charge to 100%.
right now its 2 pm i started using the phone at 9 am haevy!! besides that is my s3 that i used half as much today. Battery life on the optimus G is 60% and on the S3 55%. Battery life of the LG seem to went to normal. they claim its 40% better then on the s3. im trying tomorow on eco mode see if there is a difference.
PS: sorry for my english im italian live in canada and grew up in germany haha
I'm not so sure this is a good thing to do. I've read that you should never allow a Li-Po battery to drain completely because it physically damages it.
Then again, it's hard to find credible information on the subject.
Edit: Wikipedia cites the following article which states that overdischarging will damage the battery: http://www.powerstream.com/li.htm

Damage is when you leave battery discharged for some time, short period = almost 0. Of course there is little damage by doing this but no more than frying your phone at 100% Sorry for my english..
Fixed mine tho my battery life is crazy long now

It calls the placebo effect.
Li-polymer batteries calibrated on factory and they absolutely dont like deep discharging.
By the way LG promised 800 cycles of charging before the battery will start dying. I think in case of full discharge, the amount of cycles will be greatly reduced.
I have provisioned my battery which means going from full charge to 0 three to 4 times when I first got it and I always get a full day with medium use now.
Sent from my LG-E973 using xda app-developers app
I'm wondering, if this provisioning is so helpful for a battery, why wouldn't they do it at the factory?
After reading your guys' posts I decided to do a bit of a test.. I ran my phone all the way down from 100 to 0.. phone turned off.
Then, I turned my phone on about 5 times which then would immediately shut off onve booted to the os.
Then, I turned the phone on and placed it in the recovery mode.. doing this ensured that the screen stayed on until the phone was indeed drained entirely.
Then I charged it up till 100% before I went to bed, turned airplane mode on, closed the screen and went to bed.
Wake up this morning and looked to see how much battery drain occurred during sleep.
After about 5 minutes of using my phone it dropped down to 97%.. only lost 3% overnight. I was very pleased to see this as it confirms in my case that the phone is able to go into deep sleep.
I've also noticed that my battery seems to be draining slower than before.. before I could surf the web for ten minutes over wifi and lose a full 10% of battery.. so far today I've been on the web, downloading email, messing with some apps for around an hour or so and I'm currently at 86%.. definite improvement I believe.
And FYI this is with eco mode off, screen at 50% brightness, no gps and sync on sparingly. This is also on the latest update (my phone is on bell)

I'd be really tempted to try this, but I've heard so much from so many credible sources that total drain on Li-ion is bad news. Conflicted

It's bad to constantly cycle it full to empty. A full cycle once in a while is fine and on some devices it's necessary to calibrate the battery. Additionally, it's not good to store the battery empty. There's no harm in letting it drain all the way occasionally although killing it then further killing it in recovery is probably overkill.
Sent from my LG-E973 using xda app-developers app
Indeed, I only did it in the hopes that it would help to recalibrate the battery.. I recently was forced to run a flash back to the original firmware using the kbz method.. I was able to bring back to stock but noticed afterward that my battery life did not seem anywhere near as good as it was prior.
It could be that the kbz I flashed to was the newest updated version and it just isn't as good with the battery life but I felt it was worth trying draining all the way to see if it would help.. it does seem to have helped a bit though my battery still shows that android system keeps awake for 4+hours which is odd..
Anyway, once in a while I don't see it being a big deal.
If anyone is going to attempt the things mentioned here, why not do us all a favor and post some actual numbers from Better Battery Stats (a before and after) for some real analysis.
I'm not implying that anyone is lying, but it is just too easy to perceive an improvement when that is what one is expecting.
The plural of anecdote is not data.

according to my experience, the original one is the best
Ive noticed this phone loves to turn on the display for any reason it can think of. That is not the bad part tho. The default lock screen can be swiped any where, and in my pocket this is bad. I did a test with my palm to simulate the my leg in my pocket. If the screen wakes up for any reason, SMS notification, easy to hit power button, Low battery notification (this one i don.t get) and you hold your palm on the screen and it detects it, it will hold the screen on indefinitely without unlocking it if it lands in the right place.
This is what i imagine going on in my pocket.
http://youtu.be/l-CdaZXBVhE
I have replied to texts, made phone calls, even turned the flash light on in my pocket and ran the battery down before lunch.
I use this "pattern security" so I'm not threatened by this "unwanted phone call making" and stuffs like that, but my battery life still seems to be poor. I noticed that if I leave the device on WiFi, then it drains about 30%/night (approx. 10 hours). But last night I tried turning off wifi and data--> only 2% of battery percentage went down during the same time (10 hours!!). !!
What do you think causes this strange battery draining through the internet(wifi or data?)? The syncing, or some specifig program, or just the fact that it's connected to the web? it's very strange.
edit: of course I checked the battery stats, but there everything seemed to be normal..

I really have no idea. I had this phone since release and it's always had mediocre battery life at best. This is my second Samsung android phone, The original Galaxy being the first and i wasn't to satisfied with that one either. I received a new phone yesterday (Experia TL) so the i927 has been sitting idle. Before i put it down i did a factory reset and pulled the sim. It lost 45% of the battery since yesterday morning. Any of my HTCs would last weeks in this state. So far the TL seems like it runs off magic pixie dust compared to the i927 lol.

My battery can go pretty quickly when I get the l2_hsic wakelock. Around 5%/hr while it idle (though I do leave wifi on). It appears randomly - some days not at all, some after a few hours of being on. The only solution I've found is to shut it off and pull the battery for a minute and hope it doesn't come back on the next boot. Searching didn't pull up much except its known on a few Samsung phones. Does BBS show anything under kernel wakelock for you?
Hi,
I've recently got a Samsung Galaxy Tab S 8.4 T705 and it is an amazing bit of kit, but I am having an issue with battery life. I am only getting about 2:30hrs screen on time, even with the screen brightness on pretty much the lowest setting. I am currently only using it for emails (Gmail) and light Web browsing, so nothing taxing. It is not rooted and running the latest UK released updates. I have debloated the tab using the debloater v3 available on XDA. I've also switched off mobile data, WiFi scanning etc and I am solely usi get home WiFi at the moment. Just typing this post has used 4% of the battery charge
I've noticed a lot of people managing between 7-9hrs,so I was wondering if there is something I have missed or I am doing wrong?
Thanks in advance for any assistance.
Ross
Can you fully charge your battery play/loop a youtube video for 10 minutes and tell me how much has droped? And can you show us your battery stats/graph
I have a T700, only had it for a couple days, but battery life seems pretty poor. I mostly use it for email, browsing and Twitter.
I don't have a lot of apps, widgets or accounts refreshing. Disabled any apps I don't use as well.

Thanks for the reply. I will charge the tablet and then report back.
I just rebooted the tablet as I inserted my sim card and it went from 55% battery to 45% after the reboot.
@cjw_101 it's quite shocking isn't it. I like you have no widgets. Hoping it is just something I am doing wrong or an easy fix.
Bit of an update. I intended on running the battery out fully before recharging it and noticed some strange behaviour:
I restarted the device and it went from 55% before the restart to 45% after the restart. It then discharged over an hours use of general Internet use and switched off at 1%. I pressed the power button again and it turned back on with apparently 14% battery. It then ran down to 1% again over 10 minutes and it switched off. I turned it back on again and it showed at 1% and switched off again. I plugged in my charger while the tablet was off and it showed on the screen that the battery was 12% full.
Now just recharging it.

I heard from the same stuff as you are describing here. Maybe it would be the best when you bring back your tablet, that they can repair it/or replace the battery... because this is just not normal!
If you are rooted, I would try a custom rom from here: http://forum.xda-developers.com/galaxy-tab-s/development
Choose one of your choice and try it again with this new rom!
Thanks for your help.
I've emailed Samsung to see if they can arrange to fix it. Hopefully it won't take too long.
can you kindly provide a link the debloater v3?

I had similar problems and eratic reporting for the battery level.
tried all soft solutions (fully charge / discharge, reset battery stats, custom kernels, etc.) with no durable effect.
at last resort I opened it, unplugged and replugged the battery, and it has been functionning perfectly since, with something like 7 hours screen on time.
did that because sending it back was a bit complicated (import), but you may not be in the same situation.
hope it helps.
Thanks for the reply.
I've just had a phone call from Samsung and they've agreed there is an issue, so they will be sending out packaging for me to send it back for repair.
Thank you everyone for all your help and advice, it's very much appreciated
I sent my tablet off on Monday and received it back today, so I cannot fault Samsungs service. I'm not sure what they have done to the tablet, as they haven't advised me of the fault. They have supplied me with a new USB cable and adapter, which I assume is normal with battery related issues. I will report back once the tablet has charged and I have been able to test it more.
So I've been testing the tab since Friday and I am on target for at least 8hrs screen on time That's with the tablet being on for over 2 days straight as well. It looks like the issue is now resolved
Thank you everyone for all your help
I had the same problem with you. If I fully charged it and turned it off, the battery will be around 4% after 2 days. If I used the tablet, the battery drained a lot.
I sent it to Samsung Service Centre here. They wrote 'replaced Power IC' in the repair bill. Now the battery is fantastic. I can watch movies in MX Player Pro for 2 hours and the battery drains around 15%-ish only. You definitely need to send it in. It's hardware problem, not software.
Hope this helps.
