Series 2 Battery Drain

[pixibuex]

My Series 2 (currently watchOS 4.3) watch battery used to last 36+ hours. But for about 3-4 months it barely lasts 24 hours. I only have Sleep Watch and Carrot Weather apps. I had Sleep Watch since the beginning. So I removed the Carrot Weather complication to find out if it was the reason. But that had no effect. I haven't changed anything about my usage. Never changed the watch face. I can't think of any other reason than watchOS update. Not sure if it is a common issue couldn't find any similar threads.

Batteries degrade over time.

Batteries degrade over time.

Even in a year?

Even in a year?

Yes. It's just more noticeable in the watch because the battery is so small to start with.

As a sidenote, you can have Apple conduct a free battery test in store or over the phone, and they can determine the overall health of your Apple Watch battery. Also, sometimes there might be random glitches with Apple Watch, which you can rectify by holding down the digital crown and power button for approximately 10 seconds until you see the Apple logo.

Unpairing and repairing solved the issue.
