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....

Re: abnormal battery behaviour..
 

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.

i just plugged it to my laptop and its not charging,,,,,,,,,,

Re: abnormal battery behaviour..
 

what kind of car charger do you have?

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

Re: abnormal battery behaviour..
 

i rebooted 2 times thismorning at 10... whats the exact command pls???

Re: abnormal battery behaviour..
 

heres a screenshot i just took... summary:
5am to 10am on charge unused
10am to 11.30am on car charge + maps+intnet radio

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

Re: abnormal battery behaviour..
 

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

Re: abnormal battery behaviour..
 

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.

Re: abnormal battery behaviour..
 

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.

Re: abnormal battery behaviour..
 

Sometimes it takes a little over one hour to charge my phone. Other times it takes hours. I just make it a habit to turn the phone off and also pull battery out at least once a day. Might be overkill but I have read enough things and experienced enough to not do it. I use the charger that came with the phone and I use some sprint charger while in my car. Hope I help.

Written on N900

Re: abnormal battery behaviour..
 

whats the specs of the original charger pls?? car charger says 3-15 v max

Re: abnormal battery behaviour..
 

well, your USB -port gives 5V 500mA and I consider it a bit slow.

my charger that charges through adapter is 5.7V 800mA.

So it is your wallcharger 1750mW vs mine 4560mW.
Mine charges the battery from empty to full in about 3 hours. yours require theoretically 7,8 hours but it is possible your charger never manages to charge your device very far....

thsnkss... im heading off to get another charger

Re: abnormal battery behaviour..
 

The original wall charger Nokia AC-10 is 5V 1200mA, iirc.
The original Nokia DC-10 car charger is 5V 1200mA.

There's a weaker Nokia microusb car charger too.

Re: abnormal battery behaviour..
 

i got the same one.. and it charged like a champ.... was the chaarger problem after all... i need to look for another car charger aswell...

i got an original wall charger for 10quid and i was amazed how the guy who sells phones was looking at my phone... there was hundreds of phones in his shop bt he seemed more iattracted to mine.. and he sed : this is berry good phone !!! i dont know whether he was asking me or tellng me... lollllllllllll
