Which mobile phone battery is best ?

My S7 edge battery is on its way out & needs replacing. I have looked on Ebay & the prices vary from what i can only guess is by quality ?
Are there any phone repairers here that can recommend a retailer that sells good quality batteries for the S7 edge.

Is the 3600MAH as standard, or are there high capacity versions available ?

All I can say is you wont find one that has bigger capacity, if it says it is then it's a scam!

I bought one on ebay, said it was genuine etc, it wasn't. Bought another from my thread which was recommended and it was Genuine and perfect.

I've bought a few from here, and also changed the battery myself with a few bits from Ebay. It's not hard to do at all, just take your time and don't rush it.
