I ’ve been wearing an Apple Watch Series 4 every twenty-four hours for the past two long time . Until thewatchOS 7update come along , it generally had between 45 % and 55 % electric battery charge left at bedtime , which suggest that sleep monitoring was conk to be potential with only slight modification to my blame subprogram .

But theupdate to watchOS 7seemed to smash battery life . At first I made tolerance : installation is a fairly demanding process and I spent the rest period of Friday enthusiastically trying out young function such as the handwashing timer and hearing wellness notifications . But by Saturday it was ostensible that something more serious was buy the farm on .

Alarmed by the rapid barrage fire drainpipe the Clarence Shepard Day Jr. before , I jump to make steady checks . After a few hour the battery was at 95 % ; after an hour it was at 80 % . I took the watch off its charger at 7 am , and it was all over by 2.30pm . And things were just as uncollectible the next day .

I attempt peel back the hearing health feature film , but chop-chop eliminated them as the reason of the problem . So what was the job , and how could I fix it ? I ’ve bump a basal solution .

Unpair the watch from its iPhone andreset itto factory options . When you ’re finished , the iPhone will need whether it should pair with the watch , but for the first time you get the option to set it up for a crime syndicate member – this is new in iOS 14 and watchOS 7 .

To be on the safe side , we set up the spotter as new : do n’t restore from a backup man , since this may contain the cause of the assault and battery problem .

And this seemed to pay off thing . The solution is sustainable , as I found on Monday : after a one - hour wheel workout I still had 95 % explosive charge , and in the evening it was still well over 50%.Sleep monitoringis again a naturalistic goal .

Jason Snell ’s solution was a niggling less radical , as he reportson Twitter . face with the same job on an Apple Watch Series 5 , he was able to fix things by simply unpairing the Apple Watch from the iPhone and then pairing it again , without birth to reset all of its configurations .
