Hero 100% Awake Fix

How to tell if you have the problem:

Menu < Settings < About Phone < Status < Awake Time

Bothof ours have an awake time of 100%. According to other Android users,the lower this number is the better your battery life. So basicallythis is saying that even when the phone is off, it's not asleep. It isfully awake 100% of the time. Up time should not be the same as awaketime.

Using an app called Spare Parts (Spare Parts) you can dig a little deeper.

Spare Parts < Battery History < Partial Wake Usage < Since Last Unplugged.

Myphone is showing that the dialer has a wake lock for 16h. This appearsto mean that the phone can't sleep because the dialer has locked it.

You can also check under "Other Usage." I have "Running", "Screen on", and "Phone on." Running says:

Time spent without sleeping: 16 hours (100%).

Workaround:

Abug has been found in the HTC sms app. For some reason when you SEND atext message it puts a lock on the dialer app. This lock prevents thephone from ever going to sleep, even when the screen is off. This iscausing a HUGE drain on battery life because the CPU is still awake.The current workaround is to disable the internal sms app and use oneof the free ones from the market instead. The current tworecommendations are ChompSMS and HandCent. I personally use HandCentbecause you can give it the hero look and feel. ChompSMS forces you touse bubbles.

I've been asked by several people how todisable the internal sms app. Just open it up, press menu and go tosettings. Turn off Auto-retrieve and Notifications. Now remove it fromyour homescreen
