Even a runaway!

Have 3 batteries tested roughly on the GT-N7000 (. 30 minutes film, same display brightness, jew with 91% charging getartet):
1) Samsung (original), 2500 mAh, date of manufacture: 2012 07:28, consumption 11%
2.) mumbi, 2700 mAh, date of manufacture: PC 1409 (I think: Sept. 2014), since 4 weeks in exchange with other battery in use, consumption 7%
3. iFoxtEK, 3250 mAh, no production date found for 2 days in continuous use, consumption 10%
It is true that, Li-Io batteries boost to start yet, but I think that is a rumor, is to me at least in my years of Li-Io battery experience not noticed. This observation has been confirmed by other reviewers on my request. I would claim that the Verhätnis capacity is reciprocal to OA% -consumption. That is, if I assume the specified capacity SPECIFIED of iFoxtEK (3250 mAh) be correct, then the other would have the following capacities:
Samsung: 3250 * 10/11 = 2950 mAh, mumbi: 3250 * 10/7 = 4640 mAh. That can not be, I think. Rather, the mumbi indication when probably too high, but somewhat realistic. Then the iFoxtEK 2700 * 7/10 = 1890 mAh would, ie, about 60% of the stated capacity. I think the battery is defective and sent him back. That would be just the 2nd production runaways of 6-reviewed batteries.
