Nokia 2100 low battery life
 

Hi

I have a 2,5-year old nokia 2100, but i have a problem with it. The battery life became really short. Sometimes it shuts off when I call, even with 2-3 bars (out of 4) of the battery.
With a full recharge, the battery is almost empty after ten minutes of calling (after a few minutes, there are one or three bars more)

So I thought that the battery was at the end of his life, and bought a new one. But even with this new battery, things haven't changed much. The mobile phone really eats the battery power.

So, is there anyone who knows what to do with it?

Any suggestions are welcome ;)
