What I'll do is a factory reset. This way there are no apps and the phone is at a stock level. Plus the battery stats will have reset too. Give us a few days and I'll be happy to review it

Specifically, I'm looking at the Mbuynow 6400mAh battery for my S4. The price seems fair but with all these third party batteries, are they what they say they are? I've heard good things about Mbuynow but wanted to be sure. Has anybody bought this specific or a chinese similar 6400mAh battery and have seen an increase in battery life?

That looks like a good option for those who want extra power but not so much added bulk. Anyway anyone tried it yet or going to try it? Another one that would be worth hearing about.
