I've had my M8s from new & recently it's been doing some very odd shutoffs. Battery level indicates well over 50% when it shuts down, plugging the charger in usually brings up the yellow empty battery icon & then the charge indication will jump to 60%+
Battery drain is in the order of 1% every couple of minutes even when all apps are shut off & background processes limited to bare minimum with Battery Saver active.
I've tried factory reset & clearing cache through the recovery menu to make sure I haven't got something sucking the life out and have also tried the power-level recal. whilst plugged in from HBoot restart (holding down power, volume up & down for 2+minutes) to no avail.
Battery health is apparently good according to every app I've tried.
Currently running around with a battery-bank in my pocket to keep the phone alive.
Your battery is dead. I had exactly the same issue (dying at 44%) and had the phone RMA'd. (it was 18 months old and 14 months in use at that time)

Searched for this and didn't find it in the forum. My phone is not rooted.
I've had this phone maybe a week after launch and this issue has just started happening in the last 4 days or so. It typically seems to happen after charging and unplugging the phone. The stock battery usage app, Settings--> Applications--> Battery usage, shows no battery drain at all while showing the phone as Awake the whole time and Screen on the whole time.
The reality is that the phone was just sitting on the kitchen counter with the screen off and I hadn't touched it the entire time. Rebooting only sometimes seems to make it snap back to reality, there are times when I'll reboot or pull the battery and nothing happens, it just continues to give a false readings.
Anyone else experiencing/experienced this?
Hello,
I have a very annoying issue with my battery percentage. Typical scenario:
I unplug my phone at 100% after loading it overnight and perform some basic tasks, like for example reading news with Flipboard for a couple of minutes. My percentage already goes down to about 75% to 82% in about 10 minutes. Then I don't use it intensively, only to check the time or messages, so the percentage stays at almost the same amount for hours. When gaming, or performing other more intensive tasks, my percentage almost drops 1 to 2 percent/minute. I get "battery low" warnings at 14% and 4% and then it goes down all the way to 1%. Now I can just continue using my phone like before, for example for gaming, web browsing, for something between 40 minutes and 3 hours.
The issue is obvious: my battery percentage is not calibrated correctly. This has been occuring since more than half a year now. I had many different roms over the years, I can't blame it on one particular one.
Now, I read about a lot of ways to calibrate your phone, so the percentage is accurate again. I have tried a lot one of them. None had any effect. I tried the following:
- wiping battery stats (multiple times)
- completely unloading my phone (restarting it multiple times, boot into bootloader and waited until it just turned off by itself and won't turn on again) and then reloading it (via charger) without interruptions (everything multiple times)
- using the app "Battery Calibration" (deleting batterystats.bin)
- using the app "Battery Monitor Widget" (waited until it shows 0 mAh, then wiping battery stats
- some battery saver app
I also switched batteries with a phone that was purchased at almost the same date as mine (09/2011) and has not been modded in any way. My phone currently runs Jellytime 4.2 R11. I updated it this week, and also wiped battery stats during the installation process at 100% charge.
Any suggestions? Any help is appreciated! Thank you in advance

Easy!
Get a new QUALITY battery.
But maybe that was to obvious for others to respond.
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.
I'm not sure if it's more appropriate to post here
or on the custom ROM forum itself, but here's my battery issue:
Issue: Abnormally fast battery drain. My battery would
be fully charged, and almost immediately start draining until
it'd show 1% within 2 hrs. Screen would be off mostly (normal
use).
Been on a custom ROM since January 2017 (crDroid) and have had no problems with it since,
except 3 days ago, when the problem first appeared.
Things that are ON: LTE data (or Wi-fi), Auto apps update on
Google Play Store (never been problematic before), Location,
Things that are OFF: Bluetooth, ScreenCast, Caffeine
When I check Battery in Settings, the numbers don't add up.
I'd have battery indicator at 70% for example, but Screen,
Android System, all other apps would add up to only 7%. So
that's a whopping 23% unaccounted for.
But here's the weird thing: it drains fast until 1%, then at 1%,
the phone is supposed to initiate automatic shutdown like it has before.
When this issue cropped up, the phone keeps going for about 6 hours
or so before shutdown is started. Checking Kernel Adiutor occasionally,
I'd see a much slower decrease in voltage which probably reflects
more accurately the power drawdown situation.
Things I've done:
-clear cache (both through File Explorer and TWRP Recovery)
-clear batterystats.bin
-calibrate battery after full charge/discharge (via Root Essentials,
which basically does the same thing as manually deleting batterystat.bin,
if I'm not mistaken)
-Resetting App Preferences via Setting/Battery
None of the above has worked. Any idea what might be wrong?
My device is a Zuk Z1, with a 4100mAh battery. It usually lasts me more
than a day on normal use, but as the attached pic shows, it's at 96%
yet without having used any apps yet, has only 2 hrs of juice left.
I've tried reflashing my ROM, wiping everything including formatting data
yet nothing has worked.
I'm a light user, as I don't play games or watch videos on my phone.
Neither do I use graphics-intensive apps. I haven't used processor-intensive apps
that require constant GPS (like Google Maps, Waze) since then.
OK, I've flashed 3 other ROMs: Citrus-CAF, NucleaROM and stock, and the problem persists.
By doing the above, I've crossed out the possibility of it being the ROM. Neither is it the battery
itself, because it would've shut down by itself at 1%, yet at 1% I can last 6 or 7 hours of light use.
Anyone out there have any idea?
Hi,
I was having an issue with my phone that many are experiencing, where once under 40%, the phone would randomly shutdown and would not boot until a charger is plugged in.
I've upgraded my WWE phone to Oreo, but the issue still occurred.
However, after upgrading, I performed the battery reset trick and since then the phone shuts down gracefully at 1% as expected. I had done the trick with Nougat previously a few times but it didn't make a difference.
The trick is:
1) Shutdown the phone
2) Plug the charger in
3) Hold the VOLUME UP, VOLUME DOWN and POWER buttons simultaneously for at least 2 mins
It might be a temporary fix, so I'll keep monitoring and update but so far so good.
Battery life is still bad though (max 3hr SOT), but that's down to battery wear I believe.
