My poor battery

[Guest Cursed Chico]

I had always battery problems. I have been using for 1.5 years.

1 month ago i installed b528 rom and nowadays, the charge goes around 4-5 hours. I did not make calibration yet.

I have to charge 4-5 times in a day.

Until %50, it goes very fast. After %50, it slows down.

I dont know what will i do. Maybe buying a battery 2050 mah can help me? I dont know what to do.

The best thing seems carrying 2-3 batteries with me those charged the before night. Please tell me some suggestions.
