I originally installed the app on my Samsung S10 as soon as it became available. However, over the weekend I uninstalled it. Let me explain why.
I noticed in the last few weeks the battery life on my phone had really gone downhill. I couldn't understand why. There was nothing obvious that changed in battery usage according to the stats. I've always worked from home and MrsDaver6 continued to go into her office for work. I started to notice an interesting pattern. My phone seemed to drain more in the evenings when MrsDaver6 was home. Also now that we could go out, I noticed it drained much quicker when out in public.
It dawned on my. My phone was draining the battery much faster when other phones (presumably with the app installed) were around. As an experiment I uninstalled the Covid app and what do you know, battery life is now much better again.
The difference for me was quite significant. From easily getting a day to a day and a half out of a charge to needing to recharge part way through the day. So on that note, the app will remain off my phone, which is unfortunate and I do feel bad about it. However, until this issue can be resolved that's the way it will be for me.
