Hello, I have a serious battery problem on the HTC one m8. Whenever I boot into hboot or recovery and reboot back to the OS, the battery insanely goes down or goes up. I have examples of it happening.
Hboot to OS: 20 to 86%
OS to recovery: 79% to 5%
OS to recovery (again): 100% to 14%
Hboot to OS: 13% to 90%
Today I was on 91% when the phone suddenly went to 0% and turned off. When I plugged it in to charge the percentage showed 27%.
Can this be fixed or do I have a bad battery and need a replacement? I'm on a Rooted and Bootloader unlocked T mobile m8, on mokee 6.0.1.
Seems like a bad battery indeed, but first, try battery calibration:
"Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized."
See if this helps.
Will do this and let you know.
Looks like he didnt let us know...

OK so here is the deal.
I did the battery calibration of charging to 100 and then wipe the battery stats and then fully deplete. The following day I wanted to drain it even further down so after the phone hit zero and shut down. I then plugged it into a usb just long enough to get into recovery and then immediately unplugged it from the usb (10-15 seconds.) I just left it sitting there in recovery for AN HOUR before it shut off on it's own. I am wondering why there is that much power still left in the batteries and yet the phone still shuts down? Is there a reason the phone needs to keep that much of a reserve?
Thanks!

Well, draining a modern lithium ion battery completely is detrimental to it's lifespan, so... yes, there is a reason for the reserve.
Since i was having problems with the battery levels i thought to run the battery dry, but i noticed that the phone was not shutting down on itself ?? it kept running on 0% and voltage decreased to 3068mV ?? (isn't that way to low ?)
I tried to power it off and on again, but it didn't boot. So i put the phone on the charger and the orange led kept blinking (1sec on, 1 sec off)??
Eventually i held down the power button and then it started to charge and i could boot again.
But what's the problem with my phone ? shouldn't it shutdown @ 0% battery on itself to prevent battery damage?

same here mate suddenly the screen went off without any warning but no it did shut down but maybe not proper software shut down, since when it regained power i had fast boot off so the phone booted from the start, the power was not @ 0% when it went out, so i dont think there is a worry about hardware or battery
yea i guess one of the many bugs, its a beast that needs to be tammed
I just drained my battery to 0 and it shut down. Now when I put the charger in there is no LED, and it doesn't turn on...... what do i do??
I am on a custom ROM. Does this mean it won't charge now because the recovery doesn't support it?
Edit: eventually the red LED blinked, then after a few minutes it stayed on solid. Then I was able to turn it on.
This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/verizon-htc-one/315416-how-clear-cache-partition-stock-recovery-un-rooted-phone.html

So I received different instructions from HTC...they said 30 minutes after power off on charger, and to hold only the power button (not volume buttons - I don't know that you can hold both the volume up and down at the same time anyways) for two minutes
when i power the phone off, it still drains. for example, I charge it to 100%, turn the power off and roughly 24 hours later, i turn it back on and it's down to 70%.
if i try an alternate method for powering off, it doesn't seem to drain. if I choose Boot to Recovery, then power down from TWRP....it doesn't seem to drain.
what is this phone doing? does the normal power down cause it to hibernate or something? any way to disable this?
currently i'm on paul pizz 6.01 rom. battery is brand new.
thanks

sounds like your batteries toasted. I had a bad one too. Mine would randomly reboot my phone at 50% unless i connected it to a charger. Ordered a new battery problem solved . Wasnt spendy 12 bucks plus shipping
My model is Lenovo P2 P2a42 with 4/32Gb. Manufactured 2016-12-24. I recently purchased it.
It came fully discharged, it could not turn on before charging.
All my experiments I have tried with the firmwares:
P2a42_S048_161111_ROW_fastboot with Android 6.0.1
P2a42_S233_170404_ROW_fastboot with Android 7.0
The result is the same with any firmware.
After the firmware is always doing a full reset.
I do not install any programs.
There are no SIM cards and SD card in the device. WLAN, Bluetooth, NFC, Location are turned off, Airplane mode is turned on.
When the device is turned off or in standby mode, the battery is discharged by 10% in 8 hours.
For example, I did so. Turned off the device, put on charging, charged up to 100%, after that charged for a few more hours, turned off the charging, the device turned off. After charging did not turn on the device. After 2 days and 17 hours I turned on the device.
The battery was 20%. This corresponds to 10% for 8 hours.
The battery is also discharged 10% in 8 hours in standby mode.
I think that in both modes the reason for the fast discharge of the battery is the same. And I think that for the same reason the device came completely discharged.
I have tried video playing without pause for 13 hours 18 minutes. The battery was discharged from 100% to 37%, total 63%, which is very good. As I understand, the battery is good.
On another forum I was given such a recommendation:
"Try to calibrate the Battery first. To calibrate the battery, press and hold the Power button until the screen goes dark, about 7-10 seconds. When the screen goes dark, release the Power button and the phone will automatically reboot. Plug the phone in and let it charge overnight, using only the charger that came in the box with the phone. This process will reset the battery table and allow the phone to calibrate overnight."
What have I done.
The device was turned on and the charge was 20%.
I calibrated the Battery as recommended. The device was rebooted.
The charge was 18% when I connected the charging.
I plugged the it for 8 hours 10 minutes. Was quick charge with two zippers.
Then I turned charger off. Was 100%.
And I turned off the device.
After 6 hours 25 minutes, I turned on the device. It was 99%.
Then I pressed the power button and put the device into the standby mode.
After 8 hours 20 minutes, I pressed the power button to wake up. It was 79%.
Then I turned off the device.
After 34 (24+10) hours 30 minutes, I turned on the device. It was 28%.
I still would not like to contact the warranty service.
Can anyone say anything more on this issue?
