iPhone XS Max, watch series 4.
Before updated, the watch can use more than 16 hours. After updated, can only use up to 8hours only. Battery management shows the health up to 95%. Everytime pick up the watch after charged, it slowly fall down the percentage (which I feel really wrong on the figures), and up to around 8 hours, the watch SHUT DOWN at 63%!!!!!!! yes, is sudden dead! then I put back to charger, it restart the watch and shows charging at around 60%..... and the charging time only takes around 20mins back to fully charge 100%...... after that I can use another 8 hours, and dead again at 63%........ really really frustrated and this MUST be the OS problem (bug).........
I have try unpair and pair, didn't help. then I erase everything and set up as new watch, problem still.......
feel hopeless ..... and more like Forcing you to buy a new series 7......
a BIG fail to the watchOS update..... big big fail......
really disappointed.....
