I'm using Apple for almost all my life now, but this is the first time that Apple is really disappointing me. Since the last Watch OS update, my Apple Watch Series 5 became pretty useless now, since it will not last for even 12 hours.. Every hour that I'm checking my battery status, I lost another 10 percent.. It's frustrating to see that Apple is only recommending the Unpair > Erase > Restore method as a reply on this thread, but believe me: I really tried everything to solve this problem! I already unpaired, erased, etc. for 2 times but.. without any improvement! Please Apple, take this problem serious (as seen in this thread there are a lot of loyal customers who are experiencing the same problem..) and let us know how this problem will be solved! Our watches are worth nothing at this moment!
