%0 battery issue - phone keeps shutting off

When using the phone the battery indicator immediately drops from whatever it was at down to %0 and the phone shuts off.
When I start the phone up into recovery (Philz) it still shows the original battery percentage that was reported before the phone shut off. I rebooted the phone back up into system several times and sometimes I am able to use it for a minute or two and then it will repeat all over again: the battery drops back to %0 and the phone reboots, other times it says %0 immediately after bootup and shuts off right away.
It's intermittent, so sometimes I can go for a week or two if I'm lucky without it happening, but sometimes I can only go a few hours without being interrupted by the shutdowns. The only thing that seems to have helped me is charging my phone a little bit more and then it stops for a while, but I don't always have a charger with me so I would like to get this issue resolved if possible.
I know my battery is charged. I was able to sit there flashing my phone over and over trying to fix the issue and the phone kept working 45 minutes and even an hour later. Sometimes reflashing my ROM after wiping system, cache, etc. seems to fix the issue, other times it doesn't work.
I have done the EB40 mod to my phone, but I haven't had any issues with it. It's possible that this problem could be related to that as well, but I'm fairly confident that my battery is in good condition.
This issue has been occurring for quite a while and I have done full wipes and reflashed several times with multiple different ROMs and kernels to see if the issue was related to a certain ROM or kernel. All of the ROMs I have tried were very heavily based on CyanogenMod I believe, so if it turns out to be software rather than hardware then that seems to be the common link.
I need my phone for my job so this is something I really need to get sorted out. I have to use my phone for debugging and testing applications.
I have searched all over the web but no one I have found in any forum was having quite the same issue as me.
Does anyone know how to solve this issue? A suitable workaround if no other solution could be found would be somehow preventing the phone from rebooting when the battery reads %0 if that's at all possible.
Here's a screenshot of my battery history from today when this happened. Notice how the battery level goes right back to where it was after rebooting.

Some additional info:
My battery is still at %52 as I type this and it's still running without a problem. Battery life is great in the CyanogenMod nightlies when I'm not having this issue.
I am running the October 12th nightly. The issue started while I was using arrrghhh's kernel, and it persisted even after wiping /system, and /cache and then using just the normal kernel that comes with the October 12th nightly.

Try a different rom?

I have tried flashing quite a few different ROMs and this has happened on all of them. CyanogenMod, PAC, JellyBam, and ProBAM come to mind.

Have you tried wiping every thing and fastbooting back to stock?

No. Would that really be necessary?
I wiped /system, /data, /boot, /cache, dalvik-cache, basically everything.
This sometimes does resolve the issue temporarily, but it comes back after a while.
UPDATE: I read somewhere that this may be an issue with the battery not being properly calibrated after installation. I don't think I've ever drained the battery all the way down since I got the EB40, so I figured I'd try it.
I tried completely draining it and charging it up to %100 with the phone off and I haven't had any issues so far. Sometimes it went for a week without having issues before though, so I'll be keeping an eye on it in case there are any more issues.

G870A 5.0 battery drained in less than 1 day

I just got the AT&T update to 5.0 a few days ago, and the battery drain was incredibly fast, just like 8 hours when I first had it.
I did some checking around and finally did a factory reset from recovery, and that has helped a little. If I restart the device every few hours, it seems to help somehow...
But when I put it down at night, the battery drains down 50-60% in just the few 6 or 7 hours it lies there. I have tried apps like gsam and the stock usage monitor, and compared them to the process stats in developer mode, and come up with nothing. Most of the process stats are showing near or at 100%, by the way...
Another great side affect of the upgrade is now when I use Maps with location in high accuracy mode and hooked up to the charger, it gets really stupid hot. And it never used to do any of this before. Is this whole upgrade just a POS or is it just my device? i swear I used to get 2-3 days of battery before this. Help me save the upgrade before I roll it back to the old software, thanks.

Did you ota, or flash rooted 5.0? Sounds like a bad flash...if a factory reset didn't fix it I'd suggest downgrade back to ne4 and start fresh.
Mine and GF both g870a's and are running great on 5.0.

I took the OTA and then immediately did a factory reset.
I can't remember exactly, but also check that the OTA did not set GPS to auto update apps. I THINK it did on mine.
I'm also running great on 5.0 FYI

I checked that and it wasn't the problem. I think I pinpointed the issue... I tried running in safe mode for a day with a small improvement, but not much.
Then I went back to normal mode and deleted each app separately and after three deletes, I got rid of the Weatherbug app and all is apparently better. I found some others posts on this forum regarding this app causing problems after an upgrade as well...
Any thoughts? I kinda liked that app.

Although I like the tablet UI for this app much better...I've been running with the Weather Channel app for the last year...using static locations and not using MPoints. I am totally opposed to installing anything with Weather Bug in the name due to the amount of malware and ineffiencies found on PC versions of that app. I've forcibly removed and cleansed it from many a friends PC/laptops. YMMV.
Sent from my SAMSUNG-SM-G900A using the XDA mobile app

Now, a few days in, I can completely confirm it was the WeatherBug app. I have had three days without a charge (now sitting at 13%!) and it looks like it could go 5 without much use.
I am scared to try another weather app, but I'm gonna try the weather underground thing...

5.1.1 Battery Drain

Is anyone else having huge issues with battery drain after updating to 5.1.1. I've disabled all the crap, wiped my cache, disabled enhanced LTE. and have minimal apps installed besides stock. Just took the phone off the battery charger. It was at 100% when removed. It's been sitting for 40 min with the screen off. The battery is down to 93% already with 3% being used by Android system, 1% by system UI, and 1% by Android OS. This is nuts. I can't even get through 1/2 a day of regular use. Any ideas?

Big time. My phone isn't going to sleep. My Android System Stay Awake time is more than double my screen on time.

I'm having the same problem. I currently have Location History turned on to get more surveys on Google Opinion Rewards (I could turn that off if I wanted to); and I also know that because I'm not in WiFi during the day, the Lollipop mobile radio active bug keeps the radio awake way longer than it should. It's crazy that I can leave my phone alone during the day and watch it drop ~5% an hour because of the horrible standby behavior.

There is something wrong with your phone or app. I have about 100 apps. No problem here.
This is the international version of the phone

Or it's something to do with the AT&T version of the firmware as yours is an international version and not having issues.

Battery drain issue is related to the AT&T 5.1.1 firmware.

Sent from my SAMSUNG-SM-G920A using XDA Free mobile app

I guess it might make sense to stay on 5.0.2 in hopes of a future bootloader unlock and to stay away from a potential battery draining bug. If only AT&T would embrace a more open approach to this model phone. I only got this phone because the nexus was out of stock and I was in need of a new phone. My trusty old S3 was a godsend, with its unlocked bootloader and fully open platform. The fact that AT&T is closing up the ability to root the phone is drastic enough, let alone introducing bugs that make you want to throw the phone at the wall (battery drain).

How can I see what is keeping my phone awake without root? It's staying awake 3/4 of the time and below is a shot of my app usage. What I can tell it's a system issue, but not sure. And yes I factory reset twice and wiped cache.

Same here. factory reset cache wipe x2 and have everything non essential disabled. It's driving me nuts! This phone was a rockstar until this update. Going to best buy tomorrow and will see if the Samsung folks can reinstall the update or something. I'll post what I find out.

Battery life is worse than my old s4. The screen barely takes any of it, when it used to be more than half the battery life on my s4. Yet I still get about the same screen on time.

Yup I completely agree. Left my phone at 53% overnight and I woke up to the phone completely drained and dead. It's ridiculous.

I noticed something odd. On wifi, battery life is great, maybe 1% every 2 hours idle. But without wifi, battery life goes down 10% an hour idle.

Finally made it to the Samsung center at best buy. The guy was able to force the update again and everything went smooth. So far maybe a little better, not sure yet. I'll post when I know for sure if it worked and was a bad update.

So after the forced re-do of the update it wasn't any better. List 20% at night with everything off. Dido another factory reset and cache wipe and that seems like it might have fixed it. Only 4% list last. Not as good as it was but definite improvement. Hope this helps anyone else with same issue.

TurboRZR please update... would love to know if that fixed it before I wipe my S6 for a second time.

I too am having an issue with the new 5.1.1 update where my "Android System" is getting stuck in a stay awake loop draining my battery. Sometimes a simple restart will fix it for a few hours, but it will always come back.
I installed wakelock detector and set it up to run on a non-rooted phone. When I pulled the statistics , the biggest battery drain I had under "Android System" was diagnostic.client.network. Nothing else even came close to the drain this resource was pulling.
This was as far as I was able to get as I have no idea what that is or how to disable it if I even should.

I have resolved the issue on my S6 Edge, I even attempted a factory reset which didn't resolve the issue. I had noticed my Wifi usage in GSAM was very high (50-70%) and after some searches I found that someone else posted in a different forum (I think it was the S6 Active forum) that the issue was related to multicast being enabled on wifi routers. I disabled it on my fios router (it's in a hidden menu) and it resolved my drain. I am now at 12 days uptime without a random drain. I also had to disabled Enhanced LTE as that was causing a HUGE drain at times when I didn't have LTE. I hope this helps.

Battery drain

Hi, I have p30 pro for about 3 weeks now and the software is updated. However, I have noticed in the last few days that battery drain is happening a lot faster than it used to be. I did not install any new apps nor do I have a live theme or notification app... I think I can only get about 5 hours on screen time now, but earlier could do better.. How long does your battery holds and what is your average on-screen time? Also what is the unlocking frequency of yours in the past 7 days or so?

After update, you should clear cache via recovery so it can optimize apps back properly. For me easily 7hours sot with my Samsung gear connected 24/7 + GPS always on and that's with around 15-20% left. Also in App Launch, I don't set it to automatic. I manage them manually allowing those I want and disabling those that I don't need running in the background.

Can assure you that almost everyone here can get 7 hours of SOT. Do you have any rogue apps ? Reboot your phone into recovery, then choose Wipe Cache.

So now it's 2 am, I have charged the phone to 100% at 9:30pm, It has not be used much although it was on mobile data the whole time. This is the result now: 85% baterry, and it says "time awake" 1:06 mins. Does that mean that phone was unlocked and used for 1 hour and 6 mins after being fully charged? Since I don't think I have used it for so long, since I was in cinema for 3 hours, from 10pm until 1:30am, and only unlocked it for couple of times during the movie. Something strange is def going on. I don't have rogue apps, just normal ones and tbh just a few.
Can you please be so kind to type step by step tutorial where to find all that in settings and what to do, because I don't want to mess something up.. Thank you.

i unplugged the phone at 6:30am today its 9 pm. phone has been playing pandora thru BT since 10 am to 7pm still have 50% battery left. cant see how many hours of SOT. Battery life is amazing for me.

I'm expierencing same thing. Only about 4 or 5hrs sot. Something isn't right. Running 131 aoftware

Yes sure, shut down your phone. Then hold volume up and power key. Once you feel a vibration, then release the power button and keep holding the volume key. You should now be in recovery menu. Find Clear Cache. Then reboot when you're done. You wont lose any data. It will optimize all installed apps. The time awake you're referring to in the hardware section is the screen on time. You should also note that if your network coverage is bad, then consumption will be higher too. Try downloading this app to lock it in either 4g/lte or 3g only if coverage is bad in your area : https://play.google.com/store/apps/details?id=com.xsquarestudio.forcelte
Hope that helps. If you're still facing bad battery life, then i reckon you to do a factory reset as a last resort.

Okay, thank you very much, I will do that before my next full charge. Are you sure no data will be lost?
Ps. Update on the battery status. So it is 9:26am now, screen awake time 3:26, battery 66%, 12 hours since last charge. Only on wifi, no mobile data.

I will test it today until the battery fully drains to see what screen on time will I get.. Also, one question considering the wipe cache, will it get downgraded to original emui version that was on the phone before the update or will the. 124 update still be present?

No it won't too. Firmware can't be downgraded.

just do factory reset and start over ...

Update. 16:50 now, 23% baterry, 6 hours on screen time, 19h34min since the last charge... So it was yesterday at 9pm fully charged, not a full day of without charging, not to mention two days that others are experiencing.. Tonight I will do the cache cleanup and measure the results in the next couple of days.. If no result achieved I will do a factory reset, hoping it would fix the issue..

I have done the cache clearance, but no difference at all considering the battery drain. Can you share what is the best way to save all data before doing the factory reset? Upload it on some cloud or some other way? Also, are you guys always in normal mode or do you enable power saving mode?

If you're still facing battery drain then i guess you may have restored your apps when you first setup your phone. For call logs, sms and contacts , you may use huawei's in built cloud back up and for photos , use google photos. Then factory reset and don't restore any apps from google. Start fresh.

Any update?
I am exactly like you. Consistently getting 35 percent screen and 65 percent software

T713 (S2 8") is crashing/bootlooping, even after reset

I have a T713 on Android 7. Once the battery level is below about 80%, the tablet will often crash into a bootloop when switching between screens/apps (not while using one app).
When the battery is below 45% it will always crash as above (e.g. wake the tablet to home screen, see that battery is 45%, launch an app = bootloop).
The only way to stop the bootloop is to plug in the tablet. On mains power, the tablet doesn't crash.
I've done a factory reset, wiped cache (after using it a while, of course), tried Safe Mode. Makes no difference. The crash is always reproducible below 45% battery. Battery charge logging does not show any sudden drop in battery reading immediately before/at/after the crash.
The Accubattery app says the battery is at 82% health.
There are reports of similar phenomena in other threads and sites, usually attributed to the battery, but I am sceptical that this is the issue because there is little evidence that people actually solve it by replacing the battery (and the symptoms don't seem to support the basic assumption that there is a loss of power). Any experiences/ideas?

Like any device, who knows what has managed to get jumbled up in the image. Security patches and other updates can only overwrite so much since they are doing in place updates. Even a factory reset has to be pulling the image from the device itself where a factory image is completely clean. I know it is a PITA to set a device up again, but the fact that you can do the system stuff before installing any apps or files or anything and then see if the problem shows up immediately after imaging. If so, then you pretty much have narrowed it down to at least a hardware problem and you have less places to look (the battery for example). The last time I flashed the stock image a month or so ago, it took a security updated Feb 2019 (maybe) before I rooted and such putting it in the "modified OS" world where it will not get updates again until I flash stock again. The last actual OS update might have been around the end of 2017 beginning of 2018. Too bad since the device can clearly run builds past Nugat and has never been deprecated.

Thanks for the extra info! I'll look into doing that.

A preliminary update, in case anyone visits this thread before I finish thorough testing:
The cause is emphatically NOT the battery. After reflashing firmware and then doing a factory reset, as sliding_billy suggested above, I am unable to reproduce the problem. The tablet appears to be working fine in its current fresh state, even running on low battery power. I'm now planning to gradually reinstall apps and system updates (if any) and continue testing.

Glad that at least the initial solution is working. We'll see as you reinstall apps and complete any settings if it really was that "simple."
