device battery started draining so fast from past 1 week. phone always stay hot even in screen off state. first i thought it was custom rom problem so i tried android 11, few roms in android 10, stock android 10, stock pie then went back to clean flash oreo so many times then clean flashed pie stock also qfil flashed but result was always same device stays hot and drains battery.
the discharge rate was 10% per hour on screen off and 17% when screen on. i was thinking to change battery but device always stay hot seems like hardware problem. i don't want to lost money for battery if it is hardware problem. accubattery says my battery health is 90%.
right now im using nusantara project android 10 without gapps. using very few apps with always power save mode on in kernel holding battery drain 50%. now heating and draining is less like 5% drain per hour in sleep mode.

I recently flashed to JM5 + Lagfix 2.3, installed a few apps and played around with the phone until it dropped to 15% battery.. charged it to 100% and went out while i was on the way to my destination i was just exploring around the UI getting to know andriod a little better and I noticed my battery % was dropping like 1% per 1min.. I have the mod for battery indicator with %. my total unplugged time was 2hrs+ my battery was down to 64%. Looking at the battery usage its saying that 75% of it was taken by the display and the run timer was 38mins.. i have the brightness level at 1/4 of the way and it seems to drain unreasonably fast.. all other process was at 2-3% usage only. This never happened when I got the phone for the first 3 days ( came with DXJG4 )
Wifi/bt/gps/autosync/bgdata are all off, using 2G network also and power saving for the display is also off.
Is my battery flakey or just the OS giving me the wrong information ?
Ok so i wiped my internal SD card and reflashed JM5 + repartition again and after booting my battery when to 68% from 53%..
EDIT:
Rebooted the phone and im now getting 56% LOL!
There's a thread about resetting your battery threshold in the development section. Try that.
previously when i reboot my phone, it'll fly from ~20% to ~50% lol. it's just some calibrating issue i think. i drained it to ~5% then charged it up until it NOTIFIES me that it's fully charged(ignore the battery meter / %), wait for the popup thing specifically.
works fine for me.
Hey all,
so after 2 years using my N4 I bought a new battery since I exchanged my display and sort of damaged the original battery (it was bended, smelled strange (could also be the glue) and I had the feeling it performed worse).
In the beginning I was satisfied but now after some time, I have some weired charging effects:
Using the stock rom (Android 5.0.1), I charge the battery to 100%. If I reboot the phone, the battery percentage dropped back to something between 50%-80%. It will the charge back to 100% within a quite short time. If I reboot again, the battery percentage dropps down again, but not that much. This can be repeated several times... Further, if I boot into recovery (TWRP) after reachin 100%, it also shows something between 50%-70%. After changing the battery and flashing Lolipop, I used an app to "calibrate the battery" - don't know if this helped smth or messed up everything.
Furthermore I noticed sometimes, that battery percentage drops down instantly about 20-30% within a sec while using the phone normally.
Is it just a bad replacement battery? Or is it a issue due to Lolipop (can't say if this will happen with KitKat since I changed the battery using the developer preview and stock Lolipop only)?
Right now, I'm trying to charge the battery while beeing in TWRP and see what happens then if I boot the phone.
Edit: Within minutes, battery was up to 100% in TWRP too. I rebooted TWRP and it's now back down to 58%... So it seems that Lolipop is not the reason.
Hey guys
I have Lollipop, Kernel 3.4.0, Software Version V30-EUR-XX, original LG soft
Battery drains fast. I left phone in flight mode in sleep and it lost 8% in 6 hours. While usage it loses 1% in around every 1,5 min. This phone has so good opinion because of battery, so I guess something must be wrong. I replaced my battery a week ago, its still same.
I installed GSam Battery Monitor, no apps which would use battery significantly. By the way, no matter if I switch all the radios off or I browse web on LTE with full brightness, it shows between 26-30mA, it doesn't seem legit, does it?
I bet this firmware may be problematic. Wiped this phone twice already, by 1st time it was getting hot very quickly, by 2nd time it was lagging. It is not the way to wipe phone every 1,5 month though.
Do you know guys some quick solution on this or can recommend some other firmware?
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.
Remove "batterystats.bin" in the System folder

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.
Hi my gt-i9301i seems to be having problems with the battery indicator, from 100-50% it is working okay but when it gets below 50 it freaks out, it immediately drops to 14% then skips to 7% and after two or three minutes it turns off. When I remove the battery and put it back in after a minute it goes back to 27% but then does the same, drops immediately to somewhere near 7% and dies again. What can be the problem, I tried different batteries, calibrating the battery by dropping to 0 then back to 100 and using a battery calibration app (root) but nothing fixes it. It doesn't matter if it is the stock firmware 4.4.4 or lineageos 17.1, it does the same thing on both. Anybody know a solution? I get 2 hours SoT (screen on time) and this is not enough to get me through the day and it is my daily driver since I'm a student and I currently don't have enough money for a new phone.
Just to mention, it's not because it's set to Performance mode, it does the same on Balanced too. Battery saving mode makes the phone unusably slow.
