own my Z10 on the third month

So I own my Z10 on the third month and was getting killer battery life as long as I was on heavy data. On average I was getting 5 hours of screen time and this is unacceptable. I tried an extended battery claimed 5000mah from mpj cuz i heard something good abt them. Received it last week and I got 10 hours screen on time before hitting 1% at best so far. Yesterday I've been getting good battery life. 8 hrs 21mins of screen time and I'm still at 10%(wifi on).
