I have a fully charged battery. Voltage verified by charging overnight with the phone off. Following morning the battery is tested with voltmeter and shows 4.28 volts. Boot the phone into recovery. I'm using TWRP 2.6. In recovery, TWRP shows battery at 8%, not the 100% that it should be. The phone gets stuck in the Sprint boot screen. If I have the phone plugged into the charger, the phone works fine. As soon as I remove the micro USB, the phone shuts down on its own. Try to turn it on and it gets stuck in Sprint boot screen.
I've also tried older versions of TWRP just in case it was the recovery. I've also tried different ROMs. Same issues. So I think I can eliminate the following from the root cause: Recovery and ROM.
Possible causes are circuitry in the battery that would tell the recovery that it is only 8% full or circuitry in the actual phone that isn't recognizing the fully charged battery.
So how do I troubleshoot this?
New battery solved the problem. Anyone know if there is some type of circuitry within the battery that tells the phone the voltage?
I would've thought the phone detects the battery voltage.

I had a show running on Netflix while working at my desk this morning, when my phone froze solid. No buttons, hardware or soft, would respond. The phone was connected to AC power and was showing 100% charged battery.
I pulled the battery, replaced it, and booted up. When it came up the battery was showing completely discharged (2%). I'm rooted w/ ClockworkMod installed, so I rebooted into recovery and cleared battery state/Dalvik/cache as a precaution, but this changed nothing.
So, now my phone is powered off and charging. The battery level is increasing (very) slowly, but has anyone seen this, or does anyone have any ideas what happened?
Charge it to 100%, then wipe battery stats from recovery, then drain battery completely (no "on the go" charging), then recharge to 100%.
Okay, so my HTC One X wont charge to full, no matter what. Heres what I've tried so far...
- Wiped Battery Stats from recovery, then tried charging.
- Turned off the phone and left on wall charge for over 6 hours but still was less then 10% charged, then wiped the battery stats from recovery, and it gained 40% charge.
- When I wipe battery stats, phone does gains about 20% to 30% charge, but then starts to drain even when on charge saying "Your phone is using more power then supplied, close apps or turn off the phone."
- Once calibrated it when the charge was half, that was the only time it showed me 100% charged, but then again same problem.
Phone is rooted and running JB stock.
Any help would be appreciated....
batterystats.bin has absolutely zilch to do with this. It only logs things like 'x app ran for y ms' and does not affect the battery charge shown in any way.
Anyway, did you try charging with a different charger? Does charging from your computer change anything?
Yes, tried charging using my laptop, but still the same.
Weird problem, did some searching but can't find anything that matches my problem exactly.
My Epic 4G (running Vanir kitkat) shut off the other day when I unplugged it from my car charger to go into the store. I turned it back on and it booted past the Samsung logo, and began the boot animation so I put it back in my pocket. When I pulled it back out a few minutes later it was off again. It took me a few more restarts to realize it wasn't booting past the boot animation. Each time it loaded less and less of the boot animation. Now it will show the Samsung logo and that's it.
It will boot fully into the rom, but only when it's plugged in to a charger. This indicates to me that the battery is shot, except it seems to charge up, and will discharge if I try to continuously boot with it unplugged. Similarly, if I have it plugged in and boot into the rom I can run various android battery apps (including the built in *#*#4636#*#*) and they show the health as "Good" and give me some additional stats on it, including what seems an accurate charge level.
Is it possible the battery life has degraded so badly that 100% charge means half a second? If I unplug while the phone is on it will shut off.
Halp!
Take the battery out and "slap it" (face/back side down) about an inch or so high onto a counter top 3 or 4 times using your fingers. For whatever reason I've been able to bring batteries back to life or extend their life by doing this. I have no idea why it works.
If it doesn't work the first time then try it a several more times. If it doesn't come back to life then it's probably permanently dead.
A few weeks ago I rooted my phone with the latest version of TWRP and installed Liquid Smooth as my OS. I haven't had any problems with it until today, when it died (as expected, since I did not charge it for a few days) and I began to charge it from 0%. I began to charge it and noticed that it charges ridiculously slow even from a wall outlet. The bigger problem is that the OS detects a different battery level as the recovery tool. For example, I can leave my OS booted up while charging for 30 minutes and it will display something like 20% battery. Then if I shut it off the battery icon and the recovery tool (TWRP) will display anything ranging from 0-20%. It is random, too. One second it could be 15%, then next time I reboot it might say 5%. The problem then is that when I boot up the OS, it uses the percentage that the recovery tool displays. So if I shut off the phone when the battery displayed 30%, then next time I boot it up it will display the battery number from the recovery tool (anything from 0-30%). I have been charging and rebooting my phone for an hour now and it should say something like 60% but it only reads 21%. Is there any way to fix this? What happens when my battery really reaches 100% but my phone keeps charging it because it thinks it is lower? Is this dangerous? Any help would be appreciated.
Recently, I have replaced the battery and I have tried to completely to drain the battery and charge the phone offline up to 100% to recalibrate it, but although the offline charging logo shows the battery at 100% once I turn the phone on the battery icon shows it at 87% (and in twrp recovery as well). Again, this happens every time and this is my fourth attempt to recalibrate the battery without any success so far. I can charge it to 100% online but it looks like the phone doesn't like to hold it at 100% and quickly goes to 99% in a minute which is strange.
Another odd thing I noticed is that the battery starts to charge offline at 1% instead of 0% despite being completely drained and the phone unable to be turned on.
I also performed a total firmware reset using Odin but to no avail. Now suspicious if it's a motherboard or vendor issue. I had these issues even before the battery replacement and reflashing a stock firmware.
I'm running ArrowOS 11 with the latest bootloader (SM-960F - DBT)
