After getting back from my trip I had experienced worse battery life than before the trip and have been combing through my settings to see what the difference is. I got 57% yesterday. Then last night I remembered that I had setup my corporate email for the trip. That was responsible for a 20% drop, even with the email set to sync every hour and the data settings to shut off after 15 minutes during the day. It is after all yet another application syncing along with Gmail and Facebook (and the backup).
So this brings to my attention a couple more opportunities:
First off, I believe it is possible to setup Gmail using the corporate mail app, I would bet that it would be more efficient to have one email app syncing instead of two. I wonder what the cost per mailbox is of each app and which might be more efficient. I have two Gmail addresses that I sync, so this is fairly easily testable--to an extent.
Second, I wonder what the cost of the backup sync is. My D1 certainly wasn't using that app, though it was using the MCafee app and at some point I changed to the free version of Lookout, which I am still running.Both of those do some level of backing up--not much, but some.
I've removed the corporate account sync--don't need it. I will run today without further changes to see if I get back to around 75%. Then I will try removing the backup sync.
