LG G2 VS980 Battery Drain

So my G2 used to last me a whole day easily, my battery life was incredible, then one day, I went to sleep, with my phone at 64%, and it wasn't charging, so then I slept 7 hours, and when I woke up, it's dead, 100% dead, it wouldn't turn on, well it would but just to turn itself back off again. Anyways, I'm rooted, I have Dorimanx kernel, killed off and deleted all unnecessary apps and tasks, ect. this battery drain has no source, at least I don't think so. My battery doesn't last half as long as it used to, and I noticed my phone is always staying slightly warm now, so you may think, it's running something, that's what's killing the battery, no, nothing is running, i checked with rom toolbox manager, and nothing that shouldn't be running is running. Has this happened to anyone else? Should I just replace the battery myself? My phone would have times (before this battery drain) that it would stay warm, but even then, my battery life was amazing. ANY help at all is very appreciated.
Edit: I fixed it? I decided to reset the phone, to see of it was a tweak messing with the battery, it still dies fast, so then I went back to stock via kdz method, so this way I had no custom kernel or anything. Still the battery drained. Then I just rooted and flashed the backup I made in TWRP right before I went back to stock, that brought my kernel and tweaks all back, and then, idk why, my battery life is fine again? After 3-4 days of dieing very quickly. Idk what happened, but if you have a battery drain, try flashing the stock ROM again and then testing the phone out like that. It worked for me. Also, I had signal problems before I went back to stock, and now I have LTE everywhere I go. I'm keeping this up in case someone has a similar problem.

Note 4 battery problem after flashing some custom roms

Hi everyone, i have problem with my note 4, battery drops from 11 % to 3% very fast and charges after 85% very slow.. this problems started 2 days ago when i flashed dn5 custom rom i thought it was rom problem and flashed sixperience rom but still i have same issue also i tried battery calibration but again.... what can i do???? and my screen on time is only 3 hour. please help me, thanks.

Have you checked what's eating away at your battery? Settings => Battery (Here you should be able to see if anything is causing a drain).
If the settings screen doesn't seem to show anything, you could try BetterBatteryStats (This app will be able to tell you everything that's going on regarding running processes, wakelocks,... You should give it a day or so from a fully charged battery.)
And if even BBS doesn't show anything, I'd flash the stock firmware again (And check if it isn't the battery).

Well, in all fairness, mine is running CM 12.1, and SOT is a bit under 4hrs. Which isn't fantastic either. Quickcharge does slow down a bit after a certain percentage. You could try a new battery, but might be a waste of money.
I'm afraid I can't help you any further, maybe someone else can.

did u change ur battey? im going to buy anker battery as i know they have good ones

I am facing exactly the same problem .. I don't think buying a new battery will solve this problem.
My mobile is charging by AC very very slow and sometimes it stuck at certain percentage for hours and I tried many things but I am still facing this problem... While recharging if I removed the battery and put it again, the phone shows me that it is 100% while it was not 100% at all.
I wish someone can help us about this problem or if any of u guys tried a new battery and the problem has been solved, so please feed us back in here

Any updates!?

well after 3 4 days (i mean after flashing sixperience rom) everything is ok. discharge to 0% then wait and full charge + calibrate battery may fix issue. but still dont like screen on time. only up to 3.5 4 hours

That sounds weard...
I mean the good thing is we could change the battery.

I have a feeling this is not battery issue. it's exynos + apps running on the background. Try to root + disable unnecessary apps (maybe Android 4.4 Would give you higher SOT). I had Note 3 previously and SOT was at the level of around 6 hrs (snap processor) - now on exynos it's around 4 hrs on stock firmware (5.1.1).

[Help] Battery Drain issue in One Plus One

Hello Experts,
My Battery is draining like crazy. I tried almost everything to figure out what is the issue but could not figure out. Below are the details I gathered from the things I tried.
My battery started draining almost 30 % overnight. Initially I thought it was due to the Unofficial Marshmallow Rom, I could see Wi-Fi to be cause of this drain. Hence I tried different Roms (Cyanogen Mod, PA, DarkObas, Sultan ROM, and stock Cyanogen OS ( Past 3 versions, including latest one). but the battery drain didn't stop.
So I decided to flash PA rom again, installed OpenGapps PICO (Only Google play service nothing else). I installed CPU spy and left it over night in Airplane mode. When I checked in the morning (after 7 hours) battery drain was of 25 %. This was surprising as nothing was running on my phone and only the minimum apps were installed. At this time, CPU spy showed no abnormal wake locks and was in Deep Sleep for almost 93% of the total time. The stock battery usage showed only Mobile Stand by and usage of 50 mAh.
Can you please help me figure out what is causing the battery drain.

Did you try to disable Location>Scanning>Wi-Fi scanning & Bluetooth Scanning? I had a similar situation and started using amplify + greenify on Resurrection Remix and now I have a very good battery life...

Thank you for your reply.
Yes I already tried that. The strange thing is Battery drain is observed in Airplane mode also, while minimum apps installed(Stock apps with PA rom and Opengapps Pico package). Do you have any other suggestions.

It's really hard to judge what could be your issue, you can try different methods to find out who is the actual culprit.May be an app eating your battery or device might have nasty wakelocks,alarms etc or the battery itself would be damaged etc.
Anyways,Turn off ambient display, install BetterBatteryStats then run a full cycle and analyze entire stats of your battery, you'll get know the issue or at least a clue. If you couldn't find out the issue after BetterBatteryStats test then clean flash the a ROM(Recommends CandySix or Darkobas ) w/o GApp and give it a try

Firmware
Try a different firmware version. Here's a link :

Sounds like your battery cannot hold its charge anymore.

How old is your OPO? May be your battery life is about to over.
And this battery drain suddenly started or gradually increased?

Try diagnosing by changing the Location settings to device only. It's some weird bug with COS and CM that's making it to the latest builds of 6.0.1 . I saw that older builds in May don't have this problem.

Thank you for the reply and sorry for the delayed response. I was getting New Battery
Unfortunately, Problem still exists even with the Brand New battery. Can any hardware issue cause this issue? It's certainly not Battery problem and not software problem as well.

You really should have taken my advice earlier and diagnose before making any decisions. If your battery truly was dying, then apps like 3C and Geekbench's battery test would've picked this up as they've linear-regression curve data from aggregate sources that you could've compared to. In your OP, you stated that you saw WiFi as a culprit, but did you also know that Google Play Services (depending on version) can do location requests up to 78 times within the hour on stock apps alone? I used to have this similar battery issue, but that was related to location-requests from Google Play Services that somehow propagated to other sources based on CM13's July commit, meaning that kernels also based on this could've been affected as well. What I eventually settled for, in the meantime, is using SultanXDA's 08082016 build and so far everything looks good on Wifi regarding what I expect for typical battery performance. If I learn something, I'll come back to report on it.

I did took your advice and checked Location services. The problem occurs even with Wi-fi, 3G and Location desiabled. Also in Airplane mode with almost nothing installed (only gapps PICO package and CPUSpy)

i suggest trying old version it may help

You might wanna try that. Possibly MM eating through. I still use Lollipop too. I find no need for MM yet. Also MM feels anti-dev to me for some reason :/ Needs all workarounds for things that were previously much easy to do. Oh well. Try Lollipop and see if it helps? It'd have been my first step for troubleshooting before buying a new battery

Yesterday, I left my phone in Recovery mode (TWRP 3.0.2.0). In less then 5 hours, I observed battery drain of 20%. Same amount of drain is observed when running MM rom. I don't think changing to Lollipop will help. To me it looks like some hardware issue, can any hardware beside battery cause such issue?

Odd battery drain issue that popped up last month

I was previously running andybones' rom from 2.41.605.12 base, then found my way to resurrection remix, great rom, but some update last month killed my battery life and my ability to quick charge, phone was also in constant awake state, but I do not believe the issue was ROM specific. Either way, ran a battery stats report and it appeared that my motion sensors were keeping the phone awake. I completely wiped everything and RUU'd back to 1.19.605.9 (launch firmware), battery drain went away, rapid charging came back, phone would sleep. Performed some OTA updates and everything was fine until it got to the final version of MM 1.85.605.9, rapid charging gone, battery drain back, updated all the way through nougat and nothing changed, still draining.
I am currently back on 1.19.605.9, rooted, twrp installed. Rapid charge and no excessive drain.
What could possibly be causing this? Is anyone else dealing with this?
Here is my post with my last battery stats log

I'm currently dealing with the same thing.

Update: Ran an RUU of 2.41.605.36, then did a full wipe and installed santod40's [ROM][STOCK] 2.41.605.36, chose full wipe, unencrypted install, did some debloating of vzw software... and somehow, I have rapid charging and no wakelock drains...
I have ruu'd before and never resolved the issue. I am not sure what changed in the last RUU for me, but it worked.

...and it's back... lol

So I can't see the full log on my phone, but my phone is having a similar issue. I'm wondering if it's the same as yours. Under partial Wake Locks for BetterBatteryStats it shows NfcService:mRoutingWakeLock runs ALL of the time so my phone never goes into a deep sleep.

To be honest, I didn't even bother getting too deep in to it this time, I ruu'd back to an mm version that I know I don't have this trouble on. 1.85.605.8, and then used santod's debloated 1.85.605.9 after wiping and formatting data. The first time I had the issue, it appeared to be the accelerometer that wasn't allowing the phone to go to sleep... When I looked at the battery stats this time, it didn't seem to be my issue.
If you're s-off, you can downgrade. As much as I would appreciate certain features of nougat, it's not worth it if I have to be attached to a charger all day.
Not sure if it's an issue that carries over with my Google backup, next time I try, I might just do a fresh start and install apps one by one to see if/when it starts.

Battery percentage issue on z17s

Hi.
Yesterday I was using my Nubia z17s as always and before going to bed I decided to charge it, since battery was at around 20%.
When I connected the charger, the screen went off and it didn't wake up, no matter what I did, although I could feel the fingerprint scanner vibration when I used any of the registered fingers. So I decided to hard reboot the phone by keeping the power button pressed.
To my surprise, when the phone booted again, the battery percentage showed 3%. I left it charging overnight and now it's working but the battery percentage is stuck on 3%. I'm pretty sure it's more than that, since I've been using the phone for more than 6 hours and the battery percentage hasn't dropped a bit, and the phone is working (I've made an received a few calls).
A guy at work suggested letting the battery drain completely until the point the phone shuts itself down, and then charging the phone up to 100% while off, so the battery is calibrated and the percentage is fixed. But I've always heard that it's not a good idea to let a battery drain so much. Another problem is that I fear not being able to charge the phone again once the battery gets below 3%.
Any ideas? The phone is running latest Mokee 9 Premium.
Thanks in advance.

I had already tried that. But deleting that file just resets the battery usage statistics. It has nothing to do with the battery percentage

It seems to me that you will have to make a full data backup and perform a factory reset.
ps and which firmware in use?

Hi, I forgot replying.
I finally got the phone up and running again, and the issue seemed to be firmware related.
I was running the phone on Android Pie based Mokee ROM. I finally let the phone discharge until it shut down and charged it while off. Battery got up to 100% and the phone seemed to work fine. But, a few weeks later, something similar happened again, so I reverted to the stock firmware (still stuck at Android 7.1.1) and the battery issues went away.
I recently tested the Android 10 based Mokee and found that it reports battery level very differently than the stock firmware. Before flashing TWRP and the Mokee ROM, the phone was showing 88% battery left. Just after booting Mokee, the phone had apperently dropped to 78% and I also felt quite a huge battery drain. And it had only taken me around 5 minutes to install the recovery and firmware. So I guess the Mokee firmware doesn't handle the battery very well on Nubia z17s. It's a pity, since all the rest works very well, and I quite liked the Android 10 experience. On the other side, I was unable to make Magisk work under Android 10, and Google Pay is a must for me now, so I once again went back to stock firmware.
