I have this to write a short review decided, since I have laid emphasis on an original battery.
To my personal background: I am familiar with electrical engineering, because I have been working in this field.
I can of course be no 100% statement to need to open the battery already, but I have the impression I received the battery is an original, because:
- Processing, and writing materials absolutely on track and identical level are (fit, weight, etc.)
- The fonts of old and new batteries differ in their size, but for me that is not an argument because you would have just as well at some point may have changed during production. (Counterfeits do not see this often inconsistent from, this battery!)
- Seams and the NFC coil under the front are processed identically.
- The serial number appears plausible (So far as one can not say as a producer)
Conclusion:
Should it be a forgery, then the completely convinced by a quality in her. I doubt it though.
The battery life etc depends on a smartphone on too many factors to come to a conclusion based on these.
I am happy!
