Nokia N82 battery drain test...

One of the many questions I got asked was how long the battery of an N82 can last while playing back music before it dies. Nokia's official N82 battery specs say:
Battery: Nokia Battery (BP-6MT) 1050mAh
Talk time: up to 190 min (WCDMA), up to 260 min (GSM)
Stand-by time: up to 210 hours (WCDMA), up to 225 hours (GSM)
Still images: up to 290 pictures (with flash)
Video capture: up to 110 minutes (VGA, 30 fps)
Video call: up to 120 minutes
Video playback: up to 200 minutes (VGA, 30 fps)
Music playback: up to 10 hours (offline mode)

Well, it's an easy test, so I decided to do it. Here's the process:

First I fully charged the battery and made sure no other applications were running in the background. There is no SIM card and the phone was running on offline mode.

Plug in standard issue Nokia earphones.

I took a listen to some music and decided that 50% volume would be a reasonable level for someone to listen to music for long periods, and set it at that.

Set the music player to repeat all songs in my song library.

Note the start time.

Check in after 7 hours. Still surviving.

Check in after 10 hours, which is Nokia's official rating. Still surviving.

Finally died after 11 hours and 43 mins of non-stop music playback.

In between, I turned on bluetooth on the phone to transfer 2 songs from my laptop via bluetooth, then turned it off. After that I listen to music through my AKG271 Studio headphones for a good 1/2 hour with the volume set to 100% for my other blog entry regarding the sound quality of the N82. I then put back the Nokia earphones and turned down the volume at 50% and let the phone continue to play until it died.

You can draw your own conclusions from that...

Is it possible to compare this with the n95-3 or n95 8gb ?
Do you know how much does the 1200mAh lasts in the same conditions?
BTW, *GREAT* review(s) of the N82 (I just hope they release a 3g 850/1900mhz version soon)

It is a common issue that the official specifications of different devices are not as accurate as they should be. That about the battery generally is mistaken in almost all the cellphones. Buy Viagra Viagra
