i have my phone on charge now and the charging light is on but whenever i take the charger out it immediately says low battery. any one know why this might be and is it a known bug that i can resolve?

thanks

try reflashing it

Too many variables for a poll like this one.

With 3G and GPS on, and browsing Flash sites, two hours of MP3's and playing 30 minutes of video, I am lucky to get five hours.

3G & GPS off, browsing less Flash content, two hours of MP3. and 30 minutes of video playing I get nine hours.

Both situations are with "constant" use. The numbers would probably go up about two hours for each if more sporadic use.


The battery is not big enough for the features the N900 has- if you want to use them much and not near a power socket.

I got every day about 10 to 12 hours, all on, wifi on 10, normal use, videos over upnp, music, chat, some phonecalls, backlight full (brilliant display, so i want to have all of it). But still not enough. My old N73 had about 3 to 5 days, also 3G, video streaming, and so on ...
I will try a standby test with all off, no activities, no phonecalls, ... just to get the real standbytime.

I haven't really established normal use yet so can't really say...

Sometimes it's 1-4 sometimes 20+. I just keep fiddling with things

I am getting about 8hrs, thats with 3G & bluetooth on. With a normal amount of use. If I turn the 3G off and use only the edge and wifi for internet, making sure to disconnect after use and and with the brightness down one block. I am on day 2 1/2 right now with about 1/8 of the battery left. Thats with about 1 hour of 3g and 1 hour of wifi (making sure to change back to gsm after use), 1 hour max of mp3's, and maybe 20-30 mins of phone use. I have no active widgets.

I did a trial run a couple of days ago.

Set wifi to auto-search and auto-login (where I work I have 2 weak APs, the phone jumps up and down, I also walk between them a lot), left a few conversations open (Google chat), set my availability. Set bluetooth to on (visible), charged it at about 2 AM and took it to bed (wakes me up in the morning, stop looking at me like that).

09:00- 100%
11:00- coffee done, by now I had almost an hour of playing, showing off the device and playing video. Also, I tested the FM transmitter in the car, about 10 minutes of playback. 100%
12:00- A few calls, loads of chatting (Google Talk), some SMSs. Dropped to 80%
14:00- Wifi is taking its toll, Youtube showoff really eats. 60%. I started to worry a little, thinking it would be beeping off when I got home, so no more youtube. Continued chatting and wifi activity, a few snaps with the cam.
18:00- Battery down to 30-40%. No wifi at home, it was searching and trying unavailable networks. Some gaming.
20:00- Battery down to 20%
02:00- Still 20%

Couldn't get it to go into red, gave up and charged it. That's it for me, all day long with internet linked, browsing, playing, calling. If something really heavy comes up, I'll find a place to charge.

Because I don't use the device overnight (event tho it has BT and wifi scanning), I voted for 13-16 hrs, but really, it's all day.

IMO, all-day-networking Nokia target has be achieved.

Alas I have very poor success with the battery.
I am on AT&T so 3G is out of question anyways. Additionally, i have also disabled bluetooth, wifi and GPS.
The brightness has been set to 3 out of 5.

I dont make too many calls. But after an hour of websurfing/ radio streaming the battery was down to half. Can that be normal?

13-16 hours.

taken off charge at 9:00am
moderate playing with throughout the day
default desktop, no extra widgets added other than weather and data logger
connected to the work wifi from 9:30am to 5:30pm
only 2G available
no phonecalls
two or three texts sent

battery is roughly 85% depleted by midnight.

just got new one n900 from service... battery life is i used it two days and it still shows half a battery
