a Z10 5000mah extended battery
 

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).

That's still terrible.

How much you're using it? 8+ hrs of screen time that's well for me either.

I am a fan of extended battery;-)

did you turn on 3G all day ? if yes, it could be 10000 mah battery to solve this problem.

I intend to buy this kind of battery but if getting 2 stars for this battery, I will not buy it and just use 2 pieces of 2680 mah which are not bad right now :(

Thanks for the feedback

You might consider the fact that a Lithium Ion battery if discharged below 20-25 % generallly does not fully recover. This may be why your getting poor results.
If your normally running it down to the levels your indicate it may be wise to avoid it.
This is not a BB issue. All LI batterys have this issue.

Depth of discharge Discharge cycles
Cycle life as a function of depth of discharge

A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.

100% DoD 300 to 500 cycles

50% DoD 1200 to 1500 cycles

25% DoD 2000 to 2500 cycles

10% DoD 3750 to 4700 cycles

Come back because I just placed order for this battery. My Z10 dropped into water last week so I am in great need of a new!
