HTC One : Battery Life Issue Since 4.4.2 Update

[Tim98TA]

My battery all of asudden started dying VERY quickly. I unplug from charger every day at 5am. It sits on my desk barely being used. About 10 minutes ago, I got an alert that I only had 9% battery life left. Even if I kill the few apps running, it still is bad.
Anybody?

This works!

My original HTC One refused to update to 4.4.2 as it was locked to EE. I had a replacement (unlocked) phone sent out to me and I could update.

This update destroyed my battery though! But i've just tried and it seems to have made a massive difference!

Thanks!

Hey guys.. I found a fix for this on Verizon's community forum which worked for me. It doesn't require you to do a factory restore and you shouldn't lose any application or personal data. However I must include my disclaimer:

Try this at your own risk!

Basically you just need to wipe the cache partition via recovery mode. Here's the source post which originated from an e-mail from an HTC representative: https://community.verizonwireless.com/message/1067095#1067095

Below, I've cleaned it up a bit and modified it slightly for Virgin Mobile, but if you can find the menu options for steps #1-3 then the rest should work for any carrier.

1. Disable Fast Boot. Go to Settings > Power, and disable Fast Boot
   
2. Next enable developer mode if you haven't already. Go to Settings > About > Software Information > More > and then tap on "Build Number" about 3 or 4 times until it says you are a developer. (This is a ridiculous way to enable developer mode. I don't recall having to do this on older versions.)
   
3. Enable USB debugging. Go to Settings > Developer options > and enable "USB debugging"
   
4. Power off the phone.
   
5. Press and hold the Volume Down button and then while still holding the Volume down, press the Power button as well. You will get a menu giving you options such as: Fastboot, Recovery, Clear Storage, and SIMlock. Navigate to “Recovery” using volume buttons, then press power to select.
   
6. The screen will change to display a phone on its back, with the update symbol above it. Momentarily it will change to an image of a phone with a red triangle and exclamation mark.
   
7. Press and hold volume up then press the power button for about 3 seconds. You will see something very similar to the example shown below.
   
   e:can’t open /cache/recovery/command
   e:/ failed to mount /sdcard (no such file or directory exists)
   e:/ failed to mount /sdcard (no such file or directory exists)
   e:/ failed to mount /sdcard (no such file or directory exists)
   
8. A new screen will give you various repair and recovery options.
   
9. Navigate to “Wipe Cache” with the volume down button and select with Power.
   
10. Navigate to “Reboot Phone” with the volume buttons and select with power.
    

Now your HTC One and Android 4.4.2 should play along nicely and not destroy your battery!

This fix has seemed to have worked for my HTC one mini2 thanks for the post Josh big help
