Thanks, that's very useful info

Can you show me pictures where i can see that the white back-cover for the extended battery fits nicely on the white GS2?

It's not that i don't believe you, and i'm pretty sure a big Company like Samsung wouldn't sell defective or poorly designed merchandise, but this video (it's in italian, one of the few on Youtube that shows the extended battery's back-cover for the white GS2, even if it's shown on the black version of the phone it should be the same for the white one, skip to minute 3:00 to see the problem i'm talking about) has really made me anxious and i don't want to make the wrong purchases.

Thanks again.

I'm upping this, hoping that someone can help me. Thanks again.

See my reply #136 in this thread

this battery was great when i first got it, recently its been really strange, on idle overnight drain is about 4-5 % which is fine.
But when i use the phone a there is dramatic drop in % and when on charge it charges so quick too, example if i start charging from 20% in 5 mins it will be already at 40% ..

ive reset battery stats but that doesnt seem to work, its been like this for over a week now... any one else experiencing this?

FYI: im using an AOKP rom, not sure if this might be a factor.
I will go back to stock battery and see if i have the same experience with that

Switch pfone off. Charge it fully until it makes the full bat sound. Boot up and reset fuel gauge chip whilst phone is still at 100%. Use phone until it completely dies and switches off.. charge to full whilst off again. Problem should be sorted. Also, when you change rom or kernel it takes 2-3 cycles for battery to stabilize

Not sure if they are worth it

Mine came though the post this morning and I installed it immediately, showed 64% at 9:30am now at 42% at 1:50pm.

Gonna drain it til the battery is flat, then fully charge it and then reset the battery stats via Recovery and see how it goes.

How much the weight of the phone is increased?
