At first I was excited

I wanted to bless posterity with my opinion about this product.
I use a HTC Sensation XE and was looking for something more than a year no longer satisfied with the performance of the original batteries, it had to go about a 3/4 day to the electrical outlet. I must mention that my data connection is active all day, so I constantly synchronize my e-mail, weather, etc. Since the smartphone is my only Internet connection, I use also often the Internet, or apps to read news, FB. During the day, the WiFi connection is also still active. So on the whole I would say that the utilization is high.

Initially, I was thrilled with the battery anchor, about a month great performance. After a full charge, I could do all the above and had the evening still about 30-40% remaining power. After what felt like two months, so now, corresponds to the level of performance as that of the original batteries. So the morning fully charged start to the day and about 20h only 10% capacity (ie about 5-7 minutes on a Nachrichtenapp and c'est ca).

This is a shame, because I had hoped for, due to the numerous positive reviews, that a year or at least nine months, the battery will last at least initially consistent and good. Unfortunately not --- I'm going to look at the behavior a bit and then decide if I use my original battery again, as the performance declines not as fast as it is the anchor of the case to me!
