abnormal battery behaviour..
 
hi all ill explain the problem quickly .. will post the battery graph later in the day.... i put this thing on charge this morning at 5 till 10 and it was still charging...

i thn got in the car, put it on charge, used satnav, and internet radio, connected to my car stereo via 3.5mm hdphone jack.... its nearly 12.. that means 2 hrs i used it... i disconnected it before getting off and the battery drained... battery graph says 22 percent..... and the phone was boiling hot... its literally been on charge since 5am.....

can anyone explain this?? this is a new phone frm insurance i got on friday bcuz my previous one got broken....

It sounds like you've got a process that's running away and keeping your cpu occupied.
Reboot and see if the same behavior persists.

You should be able to find out which process it is by using 'top' in terminal.

what kind of car charger do you have?

V + mA / A information is required before one can do further assumptions.

could you please answer this simple question before you go further? because it could render rest of the speculation totally useless.

wall charger is 5v 350ma output.. its a standard nokia charger and i use the adapter with it.

5v 350mA is not much, and after the adapter, even less... Internet radio and gps use will most definitely consume more power than that charger can provide.

Edit:
Yeah with 350mA charge through the adapter, it starts making more sense.

And also, the details on your car charger would still be useful to have..

If it's as weak as your wall charger setup, then internet radio and gps will use more power than the car charger can provide.

Theoretically if the adapter was 100 percent efficient, which it isn't, and the N900 did not consume power (but it does), it'd take 4-6 hours to charge. The adapter isn't that efficient in my experience, so 6-10 hours wouldn't surprise me.
