Hi Imagemaker22,
Thanks for using Apple Support Communities. Battery life is important, and I'll be glad to see how I can help. I see you've noticed some apps are using significant battery life in the background.
As a start, have you made sure both apps are updated since updating your iOS software? Update apps or use automatic downloads
After updating the apps, see if the same behavior occurs. You may also want to try disabling Background App Refresh temporarily for those apps as a test: Maximizing Battery Life and Lifespan
"Background Activity. This indicates that the battery was used by the app while it was in the background — that is, while you were using another app.
- To improve battery life, you can turn off the feature that allows apps to refresh in the background. Go to Settings > General > Background App Refresh and select Wi-Fi, Wi-Fi & Cellular Data, or Off to turn off Background App Refresh entirely.
- If the Mail app lists Background Activity, you can choose to fetch data manually or increase the fetch interval. Go to Settings > Accounts & Passwords > Fetch New Data."
I hope this helps. Take care.
