Vivoactive 5 draining battery after 12.12 update

Hi, I updated my watch when the notification popped up and from then on my battery drains ridiculously fast. It's a fairly new watch, purchased in September and with my normal use, I only had to charge it once 5-7 days. Yesterday, I charged it while at work in late morning to 100% and today as I woke up there was only 10% left on the battery, and I didn't do any sport activities that day. At this rate, the watch is unusable since I'll probably run out of battery on my soccer practice tonight despite charging it right now. What can I do with this?

  • After upgrading to version 12.12, I experienced severe battery drain. Updating to 13.17 didn’t fix the issue. Based on my calculations, my watch now drains from 100% to 0% in just two days, whereas before the 12.12 update, it lasted ten days.

  • I've now got a different phone and all the watch battery issues are resolved.  Just gone 4 days from a full charge and still have 55% left.  It's also just a much better connection - never a missed notification being pushed to the watch, when I go to the app it's already got recent data and loads the latest in very quickly.

    I don't know which specific difference has made the difference but I went from a Huawei P30 Pro to a Samsung Galaxy A35 (don't ask why, it just happened!).

    Key differences that might be playing a role: Android 14 instead of 10, Bluetooth 5.3 instead of 5.0
