Ok, so this is really quite puzzling. A little while back my N900 (Now two years old) started discharging the battery in a matter of around 5 to 6 hours just in standby! Thinking this was the battery i bought a replacement but this has not helped even though it has now been cycled several times (tho as far as i understood Li-Ions don't really benefit from cycling)

I tried reflashing but the problem still exists!

BatteryGraph reports that the battery is reaching full capacity when charged but as soon as the charger is removed the amount of charge starts to decline rapidly. Today i removed the phone from charge 2 hours ago fully chraged (BatteryGraph reported 1221mAh) and have only used the phone to send a few texts, it has received only a few texts also, so not exactly anything heavy! Yet already now after only 2 hours of being removed from charge at full capacity the battery is down to 67% and is holding 861mAh. It's never done this before a couple of weeks ago but now it does it constantly.

Further to this looking at the cpu usage history there is nothing eating an abnormal amount of cpu cycles either so now i'm stumped as to what could be the problem other than perhaps some hardware failure.

The thing seems to be dying!
