So my original standard battery was killing the phone in around 4 hours. I purchased the slim extended battery from Verizon and for the first week I was getting outstanding battery life of close to 24 hours with a decent amount of use. Suddenly yesterday, the battery life started to reduce significantly. I noticed the android.process.acore suddenly is taking 60-70% of battery usage when it was insignificant before (dont think i would even notice it as Display would almost always be number one at 30% plus). So I am pretty sure something is going on with that - when I drill into it, it says include packages are: Launcher (which I dont think I use, I have LauncherPro installed) Contacts storage Contacts com.android.process.providers.applications com.android.process.providers.userdictionary I also noticed the "sync" icon appears way more frequently in the notification bar up top. What have I tried? Reboot, reboot and remove battery for a minute, check all of my syncing accts - Touchdown set to poll hourly at the weekend, gmail AFAIK doesnt have a setting to adjust, manual sync on contacts, no sync on Facebook contacts, other Facebook sync every 2 hours, force close android.process.acore, orce close Facebook, force close LauncherPro I still have the same problem after doing all of these and would prefer to avoid a factory reset if possible. Can anyone suggest anything? Maybe an app update has caused this? Thanks!
