A resourceful user over at community.sprint.com has discovered the cause of, and solution to, a major juice suck evident in HTC’s Hero. Apparently, sending an SMS sends a signal to the dialer, then a bunch of complicated stuff happens, and your phone never goes to sleep. Thanks a lot, messaging app.
To see how this is affecting your battery usage, go to:
Menu < Settings < About Phone < Status < Awake Time
For more detail, download a free app from the Market called Spare Parts and go to:
Spare Parts < Battery History < Partial Wake Usage < Since Last Unplugged
Is your dialer out of control? Mine too! Time to download ChompSMS or Handcent SMS.
It will take me a day or two to determine the practical difference resulting from a switch to ChompSMS, but I do text quite a bit. So… I’m hoping for substantial improvement.
Big thanks to @erickarlpeters, @the_real_Newman, and everyone else who sent this to me.
