Help My poor battery

[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. 2x 1500mAh HB4F1 Standard Battery for AT&T Impulse 4G Huawei U8800 IDEOS X5 new | eBay HOw are those?

I would first make sure it's not the rom you flashed recently, flash to another rom and see if battery improves. If it doesn't then you should think about buying a new battery.

I made calibration before doing that. It was good. My battery went 6 hours but after %60, it went %28, after %24, it went %4. I dont understand what the problem is.

I dont know yet what rom i can use to improve my battery.

The battery is a year and a half old. Just buy one, they are cheap.

I want to buy from ebay. There is about 4.5 usd. But i am afraid if it is fake and ruins my phone?
