As of today, after two months in use: The part is becoming weaker. Last night I went to bed with a full battery and this morning made me the cell phone alarm clock awake done with even just 6% battery.
I have exactly four apps on it, no Wi-Fi or other things that weaken the battery.
So I buy me now again an original battery and can of course only awarded a star. Maybe I have a "Monday-product" caught, but I can only advise against the purchase of by my experience. Sorry that there was once a cold ...
