AC Question

I have accu-battery and after a few charges it tells you your battery capacity...I have the S7 Edge new out of box. The battery was designed at 3,600 MAH, after 10 charges (4 cycles) the estimates came in at 3,390MAH..I don't understand this as I assumed I would be a little over 3600 or a little under... Not 6% of battery life already degraded. Any comments or advice. I keep my phone between 20% and 80% to minimize cycle wear. I just wondering what's going on? Did I get a phone with a bad battery or was it possibly just sitting in the store for 6 months...
 
Key word here might be Estimates. Unless you have a way to directly test the battery your fine.
 
App told me I was fully charged and to unplug when I reached 94% battery on my Tab S2.
 
I never trusted that app when I tried it on a new S7 Edge. After a month, it was telling me the capacity was 87% which is pretty near impossible.
 
I've been messing with it all day and it seems to prevent my Tab S2 from charging to 100%, stops in the early to mid 90s.
