In the last day, I noticed the fully charged battery is draining in about 5 hours.
I fully charge the 8300 each night, with the unit turned off.
When I go to charge the drained battery, it shows a full recharge, yet it drains again within hours.
Does the 8300 eventually wear out its battery, requiring the purchase of a new one?
My BB is about 13 months old.
What's my move?
The battery will lose it's ability at some point to hold a charge, however 13 months doesn't seem that long. What's the warranty period, 12 months?
Are you in an area where your phone is constantly looking for a cellular connection, where coverage is spotty? This can run a battery down pretty quickly.
Perhaps fully discharging 3x in a row and fully charging each time might be of use, to reset the meter on the battery. Nevertheless, a 13 month old battery could use replacing.
Seems like a rip, having to replace the battery after a little over a year.
I wonder if other people have had the same experience.
I haven't installed 3rd party software so I'm not overburdening the battery beyond normal use.
I've had mine for just over a year, the battery seems as strong as ever. I leave mine on all the time, I use the brightest screen lighting, I play mp3's on it over the speaker on a regular basis, and I can go a couple of days at least between charges.
Did this happen recently/suddenly or has it been like this for a while?
I will suggest again you try my recommended method of dealing with quick draining batteries. Should you find it doesn't work... get a replacement for very little money on eBay.
I got lucky, for the time being.
Went to my local AT&T store, and the guy just replaced my battery for free.
He said the BB was notorious for losing charge after around 1 year.
If the new battery doesn't fix the problem, he said they would fix the phone.
I'll report if the new battery doesn't work for this problem.
