Initially, strong performance, which quickly subsides

Initially, the battery has commanded a great performance. Then I hear a lot of music on the S3 and read messages, had with the old battery the S3 every night to the mains. The power battery but the Samsung did then twice as long.
In addition, in order to save even more energy, I had given my root privileges, and even install the CostumRom Cyanogenmod 10.2 (based on Android 4.3). Greenify, Task Killer, screen brightness at minimum and otherwise all the features that were not needed disabled.

One can say that this battery brings full power for about 3 months and then is noticeably weak. After 30min surf and two app installations go about 20% of the energy plan.
The S3 will be daily from 7am disconnected from the mains after about 17Std it must turn back. Then usually about 15-10% are still available.

Negative as well: In the summer the battery gets very warm. One should restrict to a minimum the use of the road, if the 50 ° C does not want to achieve.

The cover makes itself a good impression and absolutely looks like the original cover.
