Another battery issue?

I went to bed with the phone charged to 100% or atleast very close to it since it had been plugged into my laptop for a few hours.
Unplugged it and left it at bedside at 12:00am
Checked the time at 7:00am (didn't bother to look at battery life).
By 10:00am the phone wasn't responding, kept rebooting with a red battery icon. I plugged it into the wall charger and it booted up showing 0% on the battery.
I also had it on low power mode: everything off and mobile data set to 2g only. I also had no activity on the phone: no calls, emails or notifications.
I've done this before and I'll usually wake up to it in the 90% area of battery life, but now it's completely dead?!
Anyone haves omething like this occur?

Mm.. well, first thing I'd do is check your widgets/apps running. Some of them leave a WakeLock open, and force CPU to run at 100%.. that'd kill the battery.
Another thing to check is any big data parsing apps, like RSS with webpages for example (NewsRob).. they are excellent apps, but if you set them up for constant sync they will kill ur battery.
Unless your battery is a complete mess, there is no reason why it should drain so fast, unless there are some nasty apps running.
BTW, check out this thread: http://forum.xda-developers.com/showthread.php?t=669497
You really don't have to worry about using 2G over 3G (EDGE drains MORE power than 3G, actually) and turning everything off for battery power. Your problem is elsewhere.

It happened to me once. Woke up to a completely dead phone. I assume something I was running got out of hand. Nothing I had installed regularly kept it awake, but it could have been a bug in something that used 100% CPU, or at least kept the CPU awake the whole night.

It's small things, for example a CPU meter widget I had secretly ran a WakeLock and kept my CPU at 998MHz all the time to monitor it.
Or, could be just a poorly written app/widget. Not saying that this is the definite reason, but this is the first thing I'd check for.

how do i know if my phone is set at 324MHz even on sleep/standby?
i have it setup to 324/224 standby, but i dont really know if the phone is going to those clock speeds as soon as its on standby.

I have a few apps that sync, such as Pure Calendar / Messenger but nothing that should drain it that quickly. I hadn't installed any new apps and never had this occur, so maybe it's a bug where something caused the CPU to run at full overnight. I'll leave it unplugged tonight too and see what happens.

Exhausted every effort trying to fix this problem.. ATRIX 4G: new battery time?

I'll post everything I've tried and everything that's gone wrong here.
So initially I purchased this phone off of a friend nearly brand new, the screen had broken and had been replaced. Otherwise the phone is in perfect factory condition.
I unlocked the phone, and am using it on Rogers. APN settings working perfectly.
I installed GOLauncherEX on the phone as Motoblur wasn't doing it for me.
Battery life was crap (lasting hardly 3 hours and dying while I sleep). I found that Motoblur HOME had been running alongside GOLauncherEX. At first I simply uninstalled the third-party launcher, but then opted to grab LauncherPro+ and HomeSwitcher. This dramatically improved battery life.
Lately, I've been having issues once in awhile again. Mostly if I leave the phone unplugged while I'm sleeping (fully charged when unplugged) and we'll use the timeline 3am - 11am. It would either die completely or drop to around 15%.
As long as I could have enough charge to last me through work, I was fine with this as it was way better than what had been happening before.
This morning something extreme and unexplainable happened.. and it's the first time I took a look at the battery usage meter to see what had happened. Picture is below.
If someone could offer some tips or help that would benefit me even the slightest, it would be very much appreciated.
My bad for sneaking a link in, but it was the only way to show the issue.

Have you recalibrated?

Calibrating is something you may need to do after flashing a ROM, you can search and find a guide or you can use this app.

I have not flashed any new roms and I don't intend on doing so, but I'll check out the app you posted.
Thanks for your help,
any new ideas are still welcome.

The benefits of battery calibration are not limited to only if you flash a new ROM. Battery calibration should be the first thing you try if you are experiencing battery troubles imo, and there is allot more in depth information in the guides you could search for.
There is one more thing I can think of you can try, download Watchdog and see if there are any malicious or poorly written apps burning up your cpu/battery.

Maybe unlock the bootloader and flash a custom rom?

Go into account and sync and shut off background data. I was getting. 10-12 hours battery life and now over 30 by just doing that. Worked for a buddy at work too.

Radio is key. After I flashed radio 1.77.30p, my phone can easily using 3 days without freeze anything.

Do not use 1.97 radio and don't use task killers. 2.3.4 gingerbread does a much better job of killing tasks than Froyo did and it's unnecessary. Also, turning off background data is not necessary.

I would say it is. Apps including google will try and update and locate your phone via 3g and gps when its sitting there idle. Its not necessary if you only install apps that dont use background data, or disable them individually but some dont allow it.
I still was able to get 15 hours with data enabled and over 30 with it disabled. There is a huge difference there. I just have to open my yahoo now to update it which I dont mind.

While I appreciate everyone's replies and help, has anyone actually looked at the picture I posted?
As much as I am most definitely interested in prolonging my battery life, that picture is showing a sudden drop from 70% to completely dead, idling, screen off, while I'm asleep.

I would purchase a new battery from Motorola, It looks like your battery has one or more bad cells in it. Only thing that really explains it. Even with everything turned ON as far as data - the battery should not drop that far that fast.

i'm not entirely sure whats going on with the charge level dropping so sharply. Either something is draining your battery big time or the readout when it says 100% is incorrect.
I had issues with the battery up time as well. In my case, the battery wouldnt last more than 8-9 hours. I had to charge it two times a day. Once overnight so its 100% when i go to work and again as soon as i get home. If i charged to 100%, unplugged and went to bed, it would be at 15-20% when i woke up.
The last time i went abroad, i left the radio turned off completely. I noticed that the battery held its charge for about a day and a half.
Now i did root, unlock the BL and install CM7 on my phone. It seemed better but not that much. After i setup the phone to NOT use my 3G data connection while my wifi was on, i noticed that i was getting great battery life when i was at home but still rubbish at work.
I'm doing a test right now to see if this makes a difference or not. I have turned off data on my phone all together this morning. I charged it to 100%. Normally after 6 hours at work, my phone is at about 30-35%
Right now its sitting at 75%
the 3g is whats killing the battery, on my phone anyway. I will see how long the battery lasts without turning on my data at all. Then i will compare that with how its like with background data turned off.
I would suggest you try re-calibrating your phone's battery, i use battery calibration from the market. Then either turn data off altogether like i have or just turn background data off as the others have suggested and see what kind of a difference it makes.
While i realize you dont want to, it may help further to have a ROM like CM7 installed as it wont have all the bloatware that can further reduce the performance of your phone. You should definitely give turning the data off a go to see its the culprit before you go spend money on a new battery which may or may not fix the problem.
Best to isolate the root cause before you spend money on fixing it. If turning off the data doesnt do it, then you very well may have a battery problem.

I'll definitely try everything you've mentioned, I did calibrate my battery since I first started this topic. I'm not sure if there's a difference, if there is, it isn't noticeable. My phone died last night, and I charged it overnight again so I haven't had a chance to see if what happened the other night will happen again. Soon enough, I'll post details if I notice anything peculiar.

Since you said you bought the phone off a friend I would like to make sure you have the right battery.
The battery "must" be of the following to show the right charge level, otherwise it might appear the battery discharging very quickly.
The part/model no.: SNN5893A
Manufacturing Date: ??/April/2011 or onwards

In regards to the poster above who mentioned shutting off background data, my phone lasts 17-19 hours running CM7 with nothing frozen, background data on, and I record quite a bit of video + pictures every day. I don't use task killers either. So I'm thinking that maybe the background data thing is either actually covering up a radio problem, a carrier issue, previous ROM information leaking through, or a faulty battery as stated above that could possibly need replaced.

GSam Battery Monitor Screen Usage?

Every night, my battery is drained by 7-8% even though, GPS, WiFi, all radios are off and the phone is in airplane mode (done automatically via LLama scripts). I installed GSam Battery Monitor to try to figure out what was going on and it indicated that even though the screen was dark, it was draining the battery (and was the primary culprit). Is this accurate or is it a bug? Anyone else seeing something like this on their Nexus 4?

Mine shows 78% usage in dark.. I think that just means how much of battery total it was used while the phone screen was off. I'm taking a completely random guess here though.

So you reset the app right before going to bed and checked it first thing in the morning and in the 7 hours you slept, the main battery drain came from the screen?
I use the same app and I never noticed anything wrong. Still, battery readings are not always accurate... sometimes when I recharge my phone, it stays 100%for a few hours, then it drops 7-10% in a matter of an hour...and that's completely normal I say you shouldn't worry about it too much as long as you get satisfying usage times..

I'm not happy w/battery life and trying to track down what the culprit is. If all major services are off at night, 7-8% battery drain doesn't seem normal to me. Granted this is apples and oranges, but my iPad Gen 3 in the same configuration remains at 100% overnight.
If doing nothing drains nearly 10% over 6-7 hours, no surprise I've got issues during the day.

I've noticed the same thing, one time I didnt turn the screen on on my phone, then I went to screen and it showed 0% discharge while screen on, and 7% discharge while off. I'm running the latest version of Viper, I'm also confused and I wonder if theres some issue where maybe power is being sent to the screen even though it's not on.

After my 7 hours sleep.. Every morning my phone uses 2% battery drainage at MAX. i.e.: Wifi Edge Sync etc ALL OFF. And I am getting 4+ screen time on my phone with moderate usage. Pretty happy with the battery life so far.

Your phone probably isn't going into sleep. The Nexus 4 seems to be prone to insomnia caused by apps that don't cause a problem on other devices.
To check this download CPU Spy from the play store. Run it, reset timers to zero, and with the phone on battery (i.e. not on charge) let it rest for 30 minutes or so, then check the figures.
You should see Deep Sleep as > 90%, if not, or it is listed as an unused state, your phone isn't sleeping.
To fix this you either work forward or backwards!
Work forward:
Factory reset, install CPU Spy, run the test and see your phone is now deep sleeping.
Start installing applications one by one and after each install, run the app, then run the CPU Spy test again.
Eventually you will find the app causing the problem, all you can do is avoid that app. Note you may have more than one app causing a problem so keep checking after each install.
Work backwards:
Start by un-installing an app at a time restarting your phone in between then running a CPU Spy test. Start with any live wallpapers (even if not set to be used) you have installed, then any weather widgets. Note just un-installing is not enough, you must restart after each one.
Eventually your phone will start deep sleeping again so finding the problem app.
Hope that helps.
Regards
Phil

I tried your advice, and my phone is going into deep sleep around 90% of the time, so I don't think that it's a rogue app. I keep my phone on the dimmest setting at all times, and I only get 2.5 hours of screen on time. I have an anker battery.

[Q] LG G2 D802 battery problem after getting overheated

Hi all,
I would like to ask you(with better skills than me) something about my LG device. Once I got up after listening to music my device was approximately 42celsius degrees and i had to turn it off for 30 mins to get it on a normal temperature. After that I realized my device battery is draining so fast. I don't know why....my idea is that: because of the high temperature or it's a software bug. I plug my phone off at 6:30am and after using it a little I only have maximum 20% at 4:00pm. I'm using Alegen's 5.0.1 rom and all the people who use it said they haven't got a problem like me. I downloaded CPUz and it says my battery life is good. So please help me because I don't know what to do.
Sorry about my English.

42 is a verry low temp. My G2 have 45 in idle, doing nothing. Dont worry, there is no pb with battery

Thanks for your answer but what should I do with my battery draining? I'm using it on a very low brightness and wifi is turned off,etc...

Make a nandroid backup and then try reflashing to stock after a full battery charge. Use the phone until 5-2% and then fully charge it. Then use as normal and see if it helps. If that hasnt helped it could be battery issues.
Also when the phone heats up is it near the top beside the camera?

Maybe you have some apps which keeps your device awake, try with another rom/kernel kombination (dont use 5.0 roms to test battery as battery is better on stock based roms)

99% of the time this is the case - a rogue app running, or one of its services, keeping the phone awake and running in the background.
OP, try this: reset the phone to factory settings, restart it and then just leave it like that for 30 minutes or so. Don't even enter your SIM PIN or anything. If the phone is still heating up, the unit is defective and requires service (it is not impossible that the battery is shorting out somewhere somehow).

Under factory reset you mean I have to backup the original LG software or my lollipop rom is good?

No, just try resetting to factory defaults (obviously, back up everything important), you can do it either through the menu or the recovery.

Nexus 6p suddenly shuts down at ~20% battery left

Hi guys,
I have a problem with my nexus 6p's battery. My phone is always shutting down as soon as it reaches around 20% left. I tried a full factory reset, different roms but the problem is still present.
The strange thing: I can't boot into android after it shut down. But: I can boot into twrp. I could run my phone for 2hours in recovery mode. I made about 10 backups and deleted them immediately.
The display was on and on 100% brightness.
Is it possible to recalibrate the battery? This is so annoying!

You probably need a new battery. Download AccuBattery from the Play Store, and use it to check the health of the battery.

Yeah definitely the battery I had similar issue. For now you could just keep the battery topped up but in time will start doing it at random times.

Sounds like a battery that's done...get a replacement...they're not that expensive.

Once you emptied it in recovery, try charging and quickly (with fast charge like 10s should be sufficient) booting then without using the phone, letting the phone charge and stay 1h30 at 100%.
Then let it discharge and when you reach the 20%, you need to have the minimum discharge rate (airplane mode, no heavy app, screen off). Every like, 30mn, check your percentage and screen off again.

Has anyone had an issue similar to mine? My issue is that the phone never shuts off when i'm using it. Randomly, a couple of times a week, i lock the phone after using it, and when i go back to turn it on, i see that the phone has shut off. I can turn the phone back on without needing to put it on a charger. Running PN + EX kernel if that matters.
