"My sister's n900 (with similar setup,primary phone) lasts 3-4 days but she is not using it for browsing." Seriously?!!?! No ways could I ever get that lol

Overclocking is all just down to personal preference, if you don't play games then why bother? i jam a bit of PS1/GBA now and then so is handy to overclock but there are a few threads on here with people poopooing the idea.

Batterypatch seems to get my battery running longer but battery graph shows only a slight change in battery drain so it could just be the update to power kernel 49, no problems as others have found though so im not complaining.

I listen to a bit of tunes on the way into work, say 10mins max, emails checked every few hours, a few txts and a few calls and my phone is porbably also around the 60-40% mark my office seems to be lead lined though so having my phone connected even to GPRS kills the phone much quicker!
