Zwift Companion App battery usage on iOS


(Liz Rice [?]) #1

The new Companion app seems to use a LOT of battery on iOS. I did a 40 minute workout yesterday and it used over 70% of the battery on a 3-month old iPhone 8!

In previous releases I’ve used the ZML app for much longer, and only seen a few % battery usage - for example I’d happily have the app running, screen on, riding for a couple of hours, and not really think anything of the battery usage afterwards.  

Today I did a social ride of about an hour and saw about 20% battery drop, although more than half the time the Zwift companion app was backgrounded as I was also using Discord. On these two pieces of very circumstantial evidence my guess is that there’s something about being in the new workout screen that uses a lot of power?

I’m seeing the same thing and I logged in to post about it. I have an iPhone X and my battery dropped 54% in 1hr and 15min while using the new Zwift Companion app.

 

Here’s what it looks like in the Battery section of iOS Settings:

Hi Liz,

Thanks for posting and reporting this. This is definitely something our team is investigating.

Let me know if you have any other questions!

Same here with my iPhone 8. Companion used 10% of my Battery in roughly 12 Minutes. But that was just the case when actually viewing the workout screen. When viewing the map it used 1% for roughly 4 Minutes. The battery usage was 74% in total for today’s workout of 80 Minutes…

Same here, workout mode absolutely kills the battery. Can we have ZML back again please?

Since the last upgrade of the Zwift Companion app my phone battery will not last for long workouts.  I just completed a 65 min workout and the app basically consumed 67% of my battery.  Is there any eta for having this bug fixed?

Same problem here. The new app is unusable for a long workout. Further the phone gets HOT. I won’t use the companion app until this is fixed so please send us an email when you get it sorted.

Same issue. Workout kills the iPhone X

I also have the same issue but I did find if I do not have the workout window loaded the battery usage goes back to what I saw with ZML.  So if you want ZML back, just don’t use the workout tab.

The ssme happens to my Iphone 8. It is not possible to get a longer workout done with one battery life…

New version of Companion posted in App Store yesterday. Haven’t tested it yet but in the list of changes this issue addressed.

Same here, battery on iPhone 7 being eaten alive using app.
