Watch Active insane battery drain after update


Mine has started to settle down, but I still only get 48hours out of a charge. 
I find that different faces drain faster, I downloaded some good low energy "eco" watch faces and stop using the other ones.

I also found an "Optimise Battery" option when you scroll down from the top top and click on the battery symbol. It will stop all ***** running in the back ground. 
It's down to trimming the fat and removing the unwanted or unused apps, I will never ever use the Benji or Baxi (Siri / Alexa wanna be) and other such apps.

Hope it helps, and it will get better. Sadly I'm now just happy with a 2 day life span, but missing my 7 day Fitbit!!


I have updated the solution. Please test it if you are experiencing drain issues

I switched from Android to iOS (iPhone 8 issued through work) at the start of the year and immediately my Galaxy Watch Active started draining within 24 hours. I used to get 3-4 days between charges with Android. For a while after switching I kept the phone on battery saving mode to get throught the day but on impulse decided to try normal use again. Surprisingly, the watch was back up to 3+ days between charges. 


Recently, i inadvertantly let the battery drain completely and, after charging it back up , the usage was back down to <24 hours. So frustrating! 


I've tried factory reset, uninstallaing and reinstalling the Wearable and Health apps - nothing seems to remedy it. 


I contacted customer support and they went through the usual checklist:

  • Update the software
  • Uninstall/reinstall
  • Factory reset
  • Turn bluetooth off and on

Everything I'd already tried and nothing worked. In the end they suggested that I send the watch back to Samsung for repair, but I'm convinced the issue is not with the watch itself as I have seen that it is capabale of 3+ days use and never had any issues when it was paired with my Andoid. It seems like it's a software or connectivity issue with iOS that's draining the battery so I don't know what sending the watch back will acheive.


I'd be very grateful for any advice from other users that might have exprienced this.

Mine seems to be okay on iOS now - as long as I don't use it for tracking an activity.  It's a shame, as it is a good watch + tracker when it works, but I'm nearly at the point of binning it and moving to a Garmin or Fitbit.

Last week, my phone still had a reasonable amount of power at the end of the day, but afer an update I can watch the battery drop rapidly.  It lasted less than three hours today with zero activity. 

I am worried that Samsung is using up the power by snooping on my phone, and I no longer trust them.  Due to this lack of trust, I recently dropped all four of my family's Samsung phones and purchased iPhones.
