Not sure if this works on any other phone, however I have a A71 5g and the USB connected notification is bugging out and causing a new notification every second and it's constantly turning my phone screen on and murdering my battery. Anyways this was the temporary solution I found to just keeping my phone screen off and saving battery you go to settings, notifications, brief pop-up settings and then select show even when screen is off and disable it. Hope this helps save someone else's battery. Till next time!
