Hm. Ive turned off emailsyncing, preferrig to do it manually. Ive set battery saving mode off, Ive got twitter and RSS feeds syncing at 30 minute intervals... Dont have FB chat active either, though Im going to try having that active 24/7 next week to see if it severely hampers my batterilife.

Nothing special really. Lasts me about 2 days with 2-3 hours of ebookreading, some browsing and 10-20 smses.
