Hello, I am using the 16GB and 2GB version of the Xiaomi Mi Max. When I charge the phone, the battery indicator and percentage will be stuck for hours before incrementing normally. The problem persists even if I turn off the phone while charging (battery percentage is stuck from where I started charging for more than an hour). Has anyone experienced this issue. Charging time is still 3 to 4 hours using the stock charger but this issue is driving me nuts because if I want to charge the phone for an hour or less, the capacity hasn't increased yet.
I have only used this phone using the MIUI 8 because it updated immediately when I used it so i don't have an idea if this was an issue when it was on MIUI 7.

I’m having battery charging problems with my HTC One XT, which seems to be a common problem for the HTC One X. The main problem is the phone seems to have trouble getting fully charged to 100% and hovers around the 75% mark.
For example, I charged my phone (while on) overnight (over 11hrs+) when the battery status was at 20%. When I checked my phone in the morning, the battery status was near 0%. So I disconnected the charger and the phone turned off. I turned on the phone and the battery status was 75%. Also when I leave the phone charging while it’s on, it’s seems to be discharging rather than charging and the battery status seems to get lower.
After some searching around the forums etc, here’s what I tried:
1. Disable Fast Boot via power settings
2. Set processor limit to at most 4.
3. Manual screen brightness
4. All Wi-Fi/Bluetooth connections are off.
5. Restarted the phone a few times.
My phone is rooted with X-Revolution ROM and is brand new and is only a few days old. What could be the problem?
So fellow members, please help me solve this annoying issue.
So my phone kept discharging when I kept trying to charge it with the supplied charger. It literally went down to 0% and the phone was empty.
So I decided to use my old charger from my Incredible S and my phone is back to 100% now after a few hrs of charging.
Seems to be working fine for now. Could be an faulty charger I assume.
Hi, i have a problem with my Galaxy my Galaxy Tab 3 7.0, can not remember when it started, but the problem is with the Android battery indicator, this start when i left 40% off remaining battery. Example: im playing a game, stop playing and the battery is at 27%, lock the device or turn off the screen for about 30 or 40 second, i look back and indicates that there is 36% remaining battery.
Sometimes indicates remaining 15%, in 30 second or 1 minute, show 5%, i connect to the charger for about 10 seconds, and show 20%.
I have calibrated several times, change rom several times and in all i have the problem, also i have completely discharge the battery, let it charge all night off, when i turn on is at 100% and back to calibrate, and the problem persist. ( i use battery calibration)
If anyone know how to solve this, or know another form to calibrate the battery, please tell me.
Thanks
I have the same issue, mine takes forever to charge but drains fast then States different levels from high to low. I've used several roms but haven't calibrated yet and will calibrate when I'm fully charged. Since you said you have calibrated already I believe the best thing to do is back up your system into recovery then wipe and reflash the rom you're currently using it might help.

I am using AICP rom, sept 9 release version. I have the issue with the battery wherein the phone turns off when the battery level is at around 61%. I have tried battery calibration app more than once but it does not seem to help.
Another strange thing i notice is when the phone turns off at 61%. I connect the charger and i get the usual message from oppo about battery being low. It starts charging and it is at 0%. I let it charge for about 5 minutes and the battery level is suddenly 64% and i can turn the phone on. After that phone charges to 100% in under an hour even when using a non vooc charger. I cannot use the vooc charger with a custom rom because of the boot loop issue it gets into.
At 100% the voltage measured by CPUZ is 3886 mv.
Any idea how this can be fixed. Any help is greatly appreciated.

If your device is bootlooping with the vooc charger AND behaving strangely as described, I'm 90% certain you have failed hardware.
Either that or AICP is REALLY screwed up, check to see if this behavior occurs on ColorOS. If the battery voltage is 3.88 volts when the fuel gauge reads 100% something is VERY wrong. When charging, it should be at 4.2 or 4.35 volts (most Oppos are 4.35 thanks to a new battery chemistry and I think the Find7 uses 4.35v batteries) from 95-100% or so.
Battery calibration apps don't do anything and never have. No fuel gauge in existence uses batterystats.bin, and most of them have no interface between the kernel and userland to alter calibration.
Well i did some charging and testing and it seems like the issue is resolved.
As suggested on the oppo forums
i continued to charge even after 100% till the voltage reading was 4337 mv. Then deleted batterystats and rebooted. Phone lasted more than 24 hours and the system calibrated again. It reached 3% before dying after which i recharged again. At 100% voltage reading was 4337 mv.
Thankfully battery and hardware is not damaged. This is probably a weird android quirk.

Deleting batterystats does nothing and never has in terms of state of charge estimation. It ONLY affects the estimates of what app used the most power in Settings->Battery and NOTHING ELSE. It has been that way since the beginning of Android. Also, deleting it was pointless and redundant in this case, since charging to 100% does THE EXACT SAME THING. The only reason to ever delete this was if you had a severely failed device that never properly terminated charging, or one with a broken kernel that does not properly report charge termination to Android. (The last time I saw this were early Kindle Fire bringups back in the ICS days.)
However charging to actual proper 100% is likely what did the trick. Nearly all fuel gauge chipsets undergo a calibration cycle when charge termination occurs. More specifically, nearly all of them redefine 100% when charge termination happens.
I do agree that deletion of battery stats was not needed. But i just did it. One thing i did notice was the smaller file size when i had the issue - around 130KB. Now it is 143KB. May be incorrect file size also indicates an issue.

my mi 11x is not charge properly
when i put it on charging my battery % drops.
i am on MIUI by xiaomi.eu 12.5.4
help me..
OMG! i also faced this issue, check y thread how i solved this issue.
(SOLVED) Charging and Battery Percentage Error
Hello Everyone, Before sleeping my phone was at 36% battery, after woke up my phone suddenly showing 76% battery without any charge, after using phone for 30 minutes my phone fet switched off, it doesn't get turned on, then i put the charger and...
forum.xda-developers.com
final solution of this problem is remove the back panel disconnect the battery for 1 minute connect battery and turn on devices, problem get resolved. same issue occured in my devices phone charge decreasing instead of increasing while charging and ampere app shows 300-310 amperes only. also acc battery app not showing any cuurent flow.
Hi,
I think there's an issue with my phone. The battery voltage is over 7 (when the phone is not charging)
My other phones (pixel 6 pro and OnePlus 7 pro) have under 4 voltage.
I saw some screenshots in other threads here and I think the voltage there was also over 7
So my question is - is this normal? I read somewhere that voltage should be under 4

Mine shows like 8.8v. I think it has to be with the dual cell battery, just like on ROG I had around the same voltage.
Mine also show ard 9 volt.. The battery health is estimate 49%..likely due to dual cell configs.

yes, I think that is the reason.
It all started yesterday when I decided to full discharge my phone and let it turn off by itself. I read somewhere at some point that it's a good thing to do when you get a new phone.
so I did it, phone turned off, plugged it in the charger and wham after 2 minutes it said it is at 100%. That couldn't be right. I restarted it a couple of times but it continued to say 100%. So I did a factory reset and wouldn't you know it the battery percentage started rapidly going down from 100 and it stopped at 2% after 30 seconds. So weird. This is when I installed a battery app and was confused by the voltage displayed.
So has this happened to anyone else? After yesterday's incident I am reluctant to get my battery below 15% to avoid this happening again
