Perfect! 248

So I have now subjected the Samsung battery and the Polar Cell following the stress test:
Load -Both batteries to 100%
-wlan And Bluetooth on, Blitzer.de running in the background with GPS, screen on full brightness
-10 Min 720p Watch video
Let -Danach a benchmark run with the app "Stability Test" until the battery was at 3%.
In the Polar Cell Battery this was after 3 hours and 16 minutes the case.
The Samsung battery 3h and 1 min of the case.
Thus, the Polar Cell has about 8% more capacity which is approximately 2808 mAh.

They are my values ​​that I have not carried out under the strictest laboratory conditions). But it showed me that the Polar Cell has significantly more capacity and thus their money's worth :).
