The purpose of the extra battery and battery charger?
 

Please Help!!!

Hi there i am a proud owner of a blackberry bold 9900 and was amazed to find that when i purchased the phone that it came with an extra battery as well as a battery charger.

It makes life so much easier because i now never have to worry about a flat battery knowing I've always got a fully charged spare at hand but for the past few months i have noticed that my battery life of both batteries does not last as long as it use to and this is a great concern to me.

I'm also concerned that by constantly removing and changing batteries that i will damage my blackberry device?

Replacing your battery and changing out a spent on for a full one will not have a negative impact on your device's performance.

That said, a battery that is frequently run down will not last as long over time. Also, make sure your batteries are OEM. Cheap batteries are cheap for a reason.
