I've had my blackberry for almost a year now, and it's been fine, but suddenly last week the battery started to lose power really quickly - I charge it completely, then in a day it's down to zero - anyone got any clues?
Don't think its an app as I haven't added any (I used to have Facebook on my phone, but that killed the battery, so I deleted it about 6 months ago, and it was fine until now)
