Someone on XDA used this app (can't remember) and figured out that the latest facebook app has a bug that drains battery and uses resources when it should be sitting idle. Those of you with the FB app that uses it should log out and leave it off until a fix is made (unless u don't mind it). I did the same and my Android system usage dropped from about 47% battery usage to 17% (with cell standby and voice calls now taking up the majority of battery usage). An hour and a half later and my battery is still at 100% (when at this point and time with fb logged in, i'd trickle down to about 88%)
Hey, I was wondering if anyone else was having a problem with sub par battery life. I have not been satisfied with my G2 battery life, I only get about 12-13 hours and I am not a really heavy user. I have disabled wifi, bluetooth, gps, cell location, and syncing for everything but my gmail and exchange (set to push), and it didnt affect my battery life at all.
I noticed that "Android System" was taking up 35% of my battery, which I am pretty sure is not normal, so I decided to try a different battery monitoring app to get more details. I downloaded PowerTutor and it was showing that Facebook was using a LOT of battery life over the period of about 10 minutes, which was strange considering that I had turned off all notifications, turned off the refresh, and turned off syncing. It shouldn't have been doing anything.
I logged out of the facebook app and it no longer seemed to be doing anything. My facebook version is 1.3.2. Hopefully this will give me some better battery life (right now i am at 24% at 3:00pm after unplugging at 6:30am, but PowerTutor ate a good bit of battery life while it was monitoring)
Just thought I would post for people who might have abnormally low battery life, and see if anyone else had the same problem.
The facebook app is terrible anyways, I won't miss it. I just use a shortcut on my home screen to m.facebook.com
I'll post back tomorrow and see if my battery life has improved.
When I posted this thread yesterday I was at 24% at 3pm. Right now, at 1pm after logging out of facebook last night and unplugging this morning at the exact same time, my battery is at 68%. I have been listening to music all morning too, browsing the web periodically, and I got a few short phone calls. So unless my battery life tanks 40% in the next 2 hours, I think that being logged in to facebook definitely seems to be eating up battery on the G2.
My testing is hardly scientific, though. But I have had the phone unplugged for 6 hours and 40 minutes and im only down to 68%. Not bad at all.
Someone else should try testing a day logged in to facebook (with notifications, syncing, and refresh all off) and a day logged out of facebook.
edit: also, my Android System is down to 15%. much better.
