Actually, Li-Ion batteries prefer to be recharged early and often.

I sit in amazement at mine... i charged it 2 nights ago overnight have used it on the first day for light internet use and about 6 phone calls and numerous texts,
Is switched off overnight then back on yesterday morning and used for the same...
switched off last night back on this am... i still have 3/4 of a green battery full so judging on it's currently use i should imagine i won't need to recharge till tomorrow night :0)
The bettery life seems to be getting better and better of course i only have wifi set to always ask and make sure when i'm not using it i've swtiched the wifi off :0)

Perhaps it would be even better if you didn't switch it off, and you just used offline mode.

Ohhhhhhh i didn't know i could do that offline mode how do i do that :0)

It's still going i've not charged it yet :0) it'll last till tonight then i think i'll have to charge it overnight :0)

My battery life seems to be getting better and better..

press power button - select "offline mode" - same button when you want to go online again.

I'm impressed by the battery life you guys are getting, I struggle to get anything like this out of my HD2, should have got an N900.......

Did you add these commands into a /etc/event.d script or some other place so that it is executed automatically? I would like to do that, but I am afraid I could brick my device if this is executed too early..
