O/T Blackberry Phone Problem

Right, I've had for about a year and a half. This morning the battery was full, then right before my eyes it went straight to red, meaning I couldn't use it all day.

Is this just the normal death of a battery, or somthing worse? Just wondering if it has happened to anyone else?

Thanks in advance

What blackberry have you got? I've got the blackberry curve 9360.. Great fone but the battery life is terrible, if I'm using the net its flat within like an hour, I'm wondering if my battery needs replacing aswel

Blackberry battery is woeful anyway!
But i got a 9800 torch and never encountered this problem take it to a phone shop near by i would!

My other half has had her blackberry 8520 for around year and half amd the batt has f up!!

She charges all nite and then it goes within thr next half hour!!
