It seems that one of the biggest drains on the battery is apps synchronising constantly but I'm still confused as to how to set the phone up with this in mind! Should Background data be switched off?! What's the difference between Background data and Auto-sync in settings? Which should be on, or should both be off? I guess what I'm ideally looking for is one button I can press on my Homescreen which will sync everything when I want it to, say a couple of times a day. I'm thinking gmail, news and sports updates, weather, that sort of thing. Or am I being too fussy? It seems a shame to have such a clever phone but have to have everything switched off because of the battery. I'm tempted to have everything switched on constantly and just charge it all night every night, have it on charge at work and carry a charger in the car just in case. Does anyone else do this? If people more knowledgable than me about this (not difficult ) could post how they have their phones set up this would be extremely useful to me and I'm sure lots of other peeps! TIA I'm in danger of becoming obsessed with this - phone has only been on for 2 hours after an all night charge, I've done practically nothing with it and the battery indicator in the notification bar has already run down slightly!
