Recent 2.3.6 update and battery life
My phone is a rooted Samsung Galaxy Blaze 4G.
T-Mobile US recently pushed out a minor OS update, to 2.3.6. Some people say that this is an indication that ICS is coming soon, but I have no idea about that.
Anyway, prior to this update, my "idling" battery drain rate was under 3% per hour. That is, if the phone was just sitting on my desk unused, that was about what I got. After the update, this has more than doubled. I'm now seeing 6-7% / hour with no phone usage (or minimal).
The only significant thing I've changed is the launcher. Prior to the update, I was using Launcher 7; after the update I switched back to TouchWiz.
It seems odd to me that the native launcher would be so much less efficient, so maybe it's the update itself that's worse. I plan to do some testing of the different launchers, but I thought I'd post this now to see if anyone has any ideas about this.
