Needs root permissions pal

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.

Just a question
I bought this Mbuynow 6400 mAh battery for my s4, I have cm12 optimized ROM. (5.1.1) . It seems the phone recognised as 2650mAh, and let me a day active usage only. In the Stweaks option I changed the charging power to 1900mAh... The charging time is about 4 hours.
Its still on 24 hours usage time.
Question: Is it the max lifetime of this battery? Or needs manual calibration?
If anyone can help me please...

I currently use this battery and I can say that it is very very good considering the price. I can charge my phone and use it at medium to maximum usage and forget about charging for the next 2 days. on average I get 9+ hr sot
