I am frequently getting episode where I lose 1% of battery per 20 seconds or so.
This is particularly common when battery level is less than 30%. But as the screenshot from shows it can occur any time. It happened twice today.
Suggestions very welcome! Obviously you can see that there is frequently poor mobile signal…but this doesn’t always match up with the draining times. It also suggests that the mobile signal is worse than I would jave said from experience
