Longer story about this bug report.

My OnePlus 7T Pro McLaren would go 2 days without charge in my routine, with
day 2 morning charge above 55% for the first 8 months, I was quite impressed.
Then suddenly day 2 morning charge became ~38%. I examined phone battery stats
and there was Android System being top battery consumer with 25%+, which I
hadn't seen being above 10% before. I wasn't able to find the cause of Android
System battery drain at the time and had to switch to charging the phone every
night.

A few weeks later I started Wireshark on my workstation for unrelated task and
couldn't help but notice these 5-second keepalive TCP messages between KDE
Connect on the workstation and the phone. The phone with its screen off replied
to all these keepalive messages, which looked excessive and unnecessary. I
uninstalled KDE Connect app from my phone, went on with my task, charged the
phone overnight. Next day at charge time the remaining charge was above 60% and
Android System battery usage went lower than 10%. I switched back to charging
the phone once in 2 days.

I had to make this workaround because it makes 2x difference for me in how
often the phone needs to be charged.
