In the first two weeks of battery has about 80 hours a day to answer professionally maintained at check e-mail, Internet research, phone calls and minutes in pirvaten Breich music downloads, listen to 45 music, 20 min phone calls and even a video. Was totally begeister.
In the third weekend but the performance with the same usage sagged noticeably, to the extent it was the cell phone had every 15 hours in the fourth week to the charger.
So the battery was sent back.
From my experience not manufacture buy recommendation.
