Method #1 (ROOT ONLY)

• Charge your phone fully (don't just go by the orange light turning green check your battery under settings>about phone>>battery)
• Reboot in Recovery and get adb shell running
• Once you have adb shell (#) running type in the following commands:

mount -a
rm /data/system/batterystats.bin

• Reboot the phone immediately after running the commands
• When your phone reboots disconnect your cable and DO NOT CHARGE until the battery dies (the phone will shut off)
• When the battery dies out charge the phone like you normally would.

*We are not held responsible for any bricking or damage to your phone*

Method #2 (STOCK or ROOT)

• Charge your battery like normal
• When you see the green light unplug the phone and power it down
• Plug it back up (you should see the orange light again for a while)
• When the light turns green again, then you are fully charged.

These two little tricks may even work on other current HTC phones. Give it a try, and let us know your results.
