After 3 years my battery went limp, I built the beginning of September 2012 the same seller a battery -> was top as far as the battery and also has endured for nearly a year (at the end he did limp already above 90%). I was pleased, I ordered this time just the same again. At first I was pleased that the battery was now cheaper than half, but then came the disappointment! The "new" battery has the same APN and has been installed correctly, but it did is absolutely nothing! Display shows only the icon that he should be charged battery and the iPhone went on no more! After more than 12 hours a current I gave up and installed the "old" the nevertheless still had enough power to jump.
I then complaining that the battery and got again delivered a new one! This was clearly anderst packed (sealed) and made purely visual the better / newer impression. After installation, the iPhone jumped again on (battery shows 78%) to. Then I got the battery fully charged first in order to test how he proposes so.
Experience value after 3 days: The battery lasts quite ok by (2 days with normal use). The only unusual event: the battery jumps of about 30% to 20% and gives the impression that the first 50% last significantly longer than the last 5 =% of the charge. Therefore only 4 stars. All in all, pretty good (especially the clamp Sevice)!
