Battery good - NFC power well after the film is removed

The battery works fine in my Galaxy S3. Whether he really runs longer than the original, you would have to measure, but the price-performance ratio is very good.
Since I use NFC, it struck me directly that there were problems reading NFC tags that are hidden mounted (behind thin plastic o. Ä.), Which went smoothly with the Origial battery. Distance for NFC detection from original battery 3.5 cm and the Polar cell battery 1.5 cm.
A call to battery-star (first class service) showed that in making recently a metal-containing film was made for printing to the battery drum. The shields the NFC antenna. When the film very carefully (Attention, the NFC antenna is only a thin sheet with conductor tracks which easily breaks off and sticks only to the outer sheet and not on the housing) replaces,
NFC works properly.

According to battery-Star, the film should be changed in the future.

Would give 5 stars if the tinkering for NFC would not. The battery is then just "naked" with loose antenna, but not too disruptive, if you let him in the cell phone in it.
