Hello is they anything I can do to fix my battery? it will just switch off at 30% or sometimes 20% and when I switch back on it will say 1%
Try this :
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.

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
Hello,
I received my gold p8000 three days ago. I noticed something very strange. The Battery drains when the phone is powered off.
If I fully charge my battery and then I turn the phone off (not standby, power off!), the battery drains overnight and the next morning I cannot power on the phone, I have to plug the adapter and wait ten minutes before the phone accepts to boot
I'm on stock rom 20150815 unrooted but it happens also on 20150725.
Did anyone also notice that?
No, that is strange. Is your phone getting hot while it's off. Sounds like it is not really "off"...
Sorry for the late reply, I've been very busy.
I've experimented about my issue and I found the cause. The phone was in fact very hot. It seems that the place where I hold my phone was too small and the power button was pressed down. It seems that pressing that button drains the battery pretty fast.
Thanks a lot.
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...
