You nailed it! This is why I thought there was one out for the 5. I only had my 4 for about 2 weeks before passing it on to my wife and getting a 5. I probably had looked at one for the 4 and remembered it as being for the 5. Man, that's a lot of 4's and 5's in those couple sentences... Sorry for getting that other persons hopes up.

It will probably be like Mugen's battery where it increases by 150 to 200mah

After the first 5 cycles of charging/discharging I am still far away from the advertised 4300mAh. Now I put it in my S5 and I am testing the original S5 battery with my charger. I will report after 5 cycles what the MPJ batterys capacity is against the original battery from Samsung.
Is that the thing that displays the capacity of the battery as a figure? What sort of figures are you getting?

Sorry, I don't understand you.

What do you mean with "that"? My charger?

and what do you mean with "figure"?

My charger shows me the exact capacity it could charge and discharge in (m)Ah. My some month old original samsung battery has some more mAh than my new MPJ battery. My MPJ battery (I only ordered one piece so I can only talk about this one piece) never ever has something near by 4300mAh. And I'm not surprised. The result is what I expected. Same volume and same capacity. Often the replacement batteries have less capacity than the original ones because the housing of the battery is not fully used (one standard battery that is placed in different housings and the smallest housing determines the max. capacity).

Yes, I mean your charger.
By figure I mean some exact numbers you are getting in comparison with your original Samsung Battery.

So here I have some values from several measurements I made.

Original Samsung battery some months old:
2643mAh average from several charging cycles.

MPJ so called 4300mAh battery (direclty bought from MPJ shop):
2684mAh average from several charging cycles.

Charging end condition was max. loading voltage of 4,249V (none of the both batteries went over 4,21V) or loading current going below C/40 (which is 70mA).

I cannot say something about long term usage for the MPJ battery.

So for me the MPJ is a good alternative to the original battery but you should not expect 4300mAh or something near by this. Its simply the same as the original Samsung battery of about 2800mAh at least my copy.
