i9505 switches off at 30% charge despite changing battery - Galaxy S 4 Q&A, Help & Troubleshooting

I was using AOKP ROM. Worked fine for a few days, then my phone would shutdown at 30% charge. Thinking it was a battery problem, I bought a new battery but it still turned off at 30%. So I thought maybe it was rom's fault so now I am running Optimized LineageOS 14.1 ROM. Still it turns off at 30%. What should I do?

Does this happen with a stock ROM?

Haven't tried it. I've been on custom ROMs for a few months now, and it was all fine until last week. It's weird how the phone shuts off exactly at 30% for both roms. And then when I put it to charge, it begins charging from 0%.

If the problem disappears with a stock ROM, then you know it is probably just a software issue rather than being hardware-related.

[Q] Battery Reporting Issue

Hey guys.
I am running stock 4.4.3 rooted with xposed, and gravity box. No matter what custom kernel I use, the phone will never charge past 93%, it says it is fully charged at 93%. However when I tested with the stock kernel, it will completely charge to 100% no issue. I was wondering if anyone else had this bug, or knew of anyway to fix it.
Also this is a brand new battery, just replaced the battery. Everything else works 100%

Sometimes it happens to me too ! try to charge your phone when completely discharged and switched off !
Im in the process of draining the battery now, so I am able to try that. I flashed back stock kernel last night just to test it once more with that.
I am stuck between deciding to retest hellsdoctor+tardis mod, latest matr1x, and AK kernel for the full charge test with phone off.

Battery dying within a couple of minutes

Hi!
Guys, I have a problem and I have no idea how to resolve it. I was installing a couple of ROMs (of course after rooting my Z2 Pro and installing TRWP 3) first I think Ressurection, and then I stayed on Cyanogen. But unfortunately after installing those ROMs battery started to behave really strange. It was draining from 100% to dead within like 30 minutes...
So of course I went back to stock ROM because I thought that that was a custom ROM problem. But unfortunately the problem remained and it was getting even more strange - it was draining fast to 1% and then it stayed on the 1% for almost the whole day, and it kept rebooting a couple of times. So I rooted the phone again, installed TRWP and tried wiping the battery stats. Unfortunately the problem remained it was either draining and shutting down or it's draining and staying at 1%.
Could you guys help me with that? I think I've tried everything I could, I have no idea what to do next...

Battery Issue

So, I have been using the Moto G4 Plus ( Indian Variant -XT1643 ) for a quite few months. Then 1-2 months ago, I rooted it, first with superuser and then replaced it with Magisk. I am using ElementalX kernel. But then after some days , the battery started acting weirdly. It drains very quickly. Also if I charge the phone fully and then reboot in bootloader , it drops to 15-16 . Sometimes the phone switches off at 10% battery. Even in idle, the battery drains very fast. When charged to 100%, the battery page of settings shows something like 45-55 mins left and that too varies. Currently on 56% it's showing 51 mins left. It's just 1 hour ago when I charged my phone to 100%. Is it time to replace the battery or is it a software issue as it drops to 15% in bootloader even if fully charged. Any help is appreciated. Thanks in advance.
I have the same problem but only with magisk, wih SuperSU everything is ok ?
Alright, I will try with SuperSu and update you. Thanks for the help.
Its software issue, may be ex kernel, magisk, supersu or any other app is draining it. Use better battery stats or similar like it and see who is sucking your battery juice.
And as you have already rooted your phone then try any custom rom as they dont have its problem (some may have also). And if wanna stick to stock rom then reset your phone and root it and then use for a while you will get the difference from before and now.

Ok. Its good to know that it's a software issue. I already tried factory reset but it didn't help. Strangely, the battery is fine now. I drained it completely and charged to 100%. Maybe that might have reset the battery stats or something. Anyways , if the problem still persists I will try custom ROM. Thanks a lot.

Hmmm, I never had battery drain issues while using ElementalX kernel rooted with Magisk (14.0).
At least not while using Motorola stock Nougat with the above.
Maybe your battery just lost its calibration as you assumed.

Random reboots on all roms

Hey guys previously I was using AEX rom and then today it started rebooting 10-15 times in an hour so I changed the rom to Pixel Experience Rom but no chill same situation but frequency has reduces to 5-6 in an hour any help will be appreciated
Also no modifications done I was using stock Rom.
And battery is weired sometimes it show 100 % or 1% or 0% while it is continuously on charging
Likely to be because of battery defect. When I faced a similar problem with another device, the official service center tested the battery and it showed significantly low voltage which was said to be the reason for reboots.
Happened same with me after installing radio active kernal. Try flashing stock rom with qfil.
i'm using mokee 7.1.2 19-1-11 release. got no bootloops

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.
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.
