Last week, a number of Apple Watch owners noticed that their batteries were draining much quicker than normal after they installed the latest watchOS version 10.1. Now, Apple has acknowledged the issue in an internal memo seen by MacRumors, and promised that a fix will arrive in an upcoming update.
The issue is affecting multiple models including older ones like Watch SE and Watch Series 5, up to brand new versions like Apple Watch Ultra 2, according to Reddit, Apple's Support Community, X and other sources. The issue appears to be fairly serious, with one user noting that "watchOS 10.1 is killing the battery on my Apple Watch," draining it from 100 to 50 percent in less than 60 minutes.
Apple appeared to address the issue partly with its iOS 17.1 update, noting that it resolved a problem involving "increased power consumption" when a Watch running watchOS 10.1 is paired with an iPhone using iOS 17, as MacRumors noted. That doesn't seem to have fully resolved the issue, though.
Apple said in the memo that the issue will be fixed in a watchOS update "coming soon," without providing a more specific date, specific models affected and reason for the problem. Given the nature of it, however, we'd hope it's a high-priority item. Apple is reportedly set to release iOS 17.1.1 for iPhone, and will hopefully also release watchOS 10.1.1 with a fix.
