Not surprisingly, the thickness and weight of the phone are thereby changed. But if the evil has not increased thickness, however the Samsung comes with the battery shell fits perfectly, nothing exceeds. It is sufficiently well done to visually diminish the gain in thickness, which remains consistent.
Like the weight gain: the battery is heavy.
The day I put the kit, I really saw a difference, but I got done quickly, and I can not remember my phone before. Sign that it is not traumatizing ...
In the end, the gain in usage time than offsets these disadvantages beside which it seems difficult to go when buying a long battery life.
Exactly what I wanted.
[Edit:] always satisfied (3 months of use), the battery and the hull seem robust.
I read somewhere (as I pointed out) that the battery took 24 hours to load, this is absolutely not my case. CF reviewed in response thereof.
