So I have been one of the fortunate ones to not have any battery issues since I've owned my TB since release date, I would average about 11-12 hours (Standard battery). All of a sudden, the last 3 days, after 4 hours of being off the charger my phone is down to 30%. I checked the battery section in settings and saw that the Android System is now taking up 35% when it used to be below 10%. Anyone happen to know why this is and/or how it can be fixed?
I have noticed that occasionally, when I update a Market app, that it resets the default values for "background update" and "notify of updates in notification bar" and "notify of breaking news", etc. Even though I had all of that turned off previously. So, if you have updated any apps lately, take a look and see how they are set. Also check the main Market apps setting of "notify of app updates" (I turn mine off and check manually). Also, each app from the Market also allows you to select auto-update or not. I turn those off too.
You might think, what's the big deal with auto-updates or notification bar notification. Well, nothing is inherently wrong or terribly power consuming about those things. UNLESS, you just happen to have a misbehaving data signal and/or a misbehaving app that, when the data connection fails, continues incessantly attempting to connect and update, ad nauseum - until your battery runs down and/or your phone overheats. That's why I prefer to do most things manually. Whatever apps I allow to auto-sync or auto-update, etc., I watch very closely. And it's not hard because there are not many. Maybe Mail, Temperature. Not too many.
Just my thoughts.
