I have now tested the battery for a few days. My S5 I take every day at about 2-3 hours using Navi, ca 10 - to make calls for 20 minutes approx to surf 20 minutes. WLAN and Bluetooth are never turned off for various reasons. Lighting is set to "automatic". The original battery I had used 6 weeks after buying the phone ca. It was then already occasionally arrived in the evening at 15%, that is far too little. When my old S4 I had a power battery of anchor. Those things are really very good. Only the provided cover is a bit strange and the phone works by clunky. Therefore, I have now bought the S5 the original Samsung here. It is optically perfect and continues to offer the usual water protection. The mobile phone is only slightly thicker and slightly heavier, but which I personally like better, since it is now even better in your hand.
At the beginning of the offer you Samsung High Capacity Battery Set EB-EG900B was still a little weak on the chest. After approximately 5 charge cycles it has now unfolds its full force. At present is the battery in the evening at about 40% so that's a significant improvement.
