No man..I have it since september, box says it was made in August 2016. I got it with fpc sensor,..@RN3Pro If your battery results are true. You probably have a fairly new device. Enjoy it while it lasts.
I have my Kenzo since last July and would be lucky to get 5 Hours SOT!
Had flashed countless roms on it... Really heavy use and still I hit 10h + on most roms, but the beat results i get with miui and NOS. By the way, batteries are like 15€, so not a big deal if it wears out.
