how long should it last?
Just curious..

I think it really depends on how much surfing or IM traffic you do. Mine varies from 12 to 24 houirs, but I surf a lot.

Hope this helps.

i took my backlight brightness down to 20 percent and the battery seems to last way longer...

I have my backlight set to 50% and to turn off at 20 seconds and my LED coverage indicator turned off, and I am constantly using mine and it lasts for 3 days. For instance, I last charged my 8700c Friday night and will charge it again tonite. So it lasted all day Saturday, Sunday and Monday. Also, that was in bad coverage and was going in and out of service the whole time, so that took away from the battery power as well.

Your carrier's configuration can impact that a lot as well (create a lot more chatter with the device than is necessary). Regretably, this is transparent (and most wouldn't entertain changing it from users). With any luck, these parms will get cleaned up over time.
The batteries in the 8700's do retain some minimal memory if you (like me) don't like to see the bat level to get low and charge it often. Every now and then (when convenient) let it run all the way down (maybe get a spare battery - in the event the timing of the exercise doesn't work out).

Like, im connected to the edge network all day.
I dont surf, I write emails and send and my batteries almost dead by 4:00.. start at about 8....

Seems very short...
does anyone make a higher capacity after market battery?

Like, yes, my young padawan.

Verily, I say unto thee, the Search fuction is good...

But, to save both of our times...


Just got mine yesterday. It does make the back bubble out some, but the extra 80~85% capacity is well worth it...

Excellent vendor and service....

Your reception will also affect battery life. If you're spending time in poor reception areas you'll get less battery life.

I find my bluetooth headset is killing my battery life. Without the headset I'm usually at 50-65% by the end of the day. Using the headset on the same number/time of calls my usage is down to 10-20%. My guess is the BB isn't going into standby mode when not on a call.

I don't use any IM, but I use it as a phone as well quite a lot. My battery easily lasts for 3 days.
