PSP battery drains fast?

Blackberry curve 9300 drains battery so fast? :/?

• i have a blackberry curve 9300 , and late last year my phone would last about 30 minutes or less on a full charge. so i had bought two new batteries. i fully charged the new one, and it worked perfectly for the past few months. but lately , its been having the same problem. it now lasts about half a day on a full charge, or so. its very annoying. and it lags ALOT. the little clock symbol comes up often, and slows down. sometimes i have to remove the battery and reboot it so it'll work. anywho, i put in my new battery and fully charged it and its having the same issue. even with the second brand new battery? help?
