I can see so far no performance degradation. After 4 months Duration Use the battery is subjectively still at its initial performance.
I also run any overly conscientious battery maintenance. Charging the phone constantly when I'm at home, so it is charged when leaving the house.
When I have no way to permanently store, he stops at my intensive use more than 1.5 days, and I invite the original battery already after one day need (using no power saving settings on meinerm note).
The battery is also subjectively not so hot during charging. In addition, it is somewhat easier. The difference in weight is -in my opinion- demand therefore that the battery is not in metal [my silver / greyish aluminum sheathing (?) Of the original] is framed as the original battery.
The dispatch from UK has also worked perfectly.
Can astonishingly highly recommend this battery. Had a cheap replacement battery expected of is serving in an emergency, but was very surprised.
