Good workmanship. externally the battery is pretty true to the photo. autonomy is significantly better than the original battery without being extraordinary. Using my little daytime telephone (internet mails and some videos in the morning before leaving, some messages and calls during the day and then mails and Internet videos and messages and calls in the evening without self or Bluetooth synchronization in the fair day WiFi at home) I end my work day with a 18h average 60/70% and 10/15% at bedtime. I recharge every night. It's just okay. Should I try to keep the synchros etc. activated to see the difference. short is better than the original battery. The NFC chip works but it is originally in the battery or in such a way I'm not sure. When in doubt I bought one with NFC. Summary: an honest battery manufacturing, which offers a significantly better battery life. I recommend.
