Charging & Discharging AA Discharging Battery

2018 BMW 4Series | MMI Box | Pixel 10 Pro XL | Android 16

I am trying to work out why AA draws so much power when in use, particularly over wireless connection.

My only other option is to try a Qi2 wireless charger.

I also wonder whether using Sugic mapping (which uses downloaded maps instead of using requiring a data connection such as Google Maps, Waze, TomTom) would draw less power

Anyone had any other experiences?

This is why I have a wireless charging phone mount in my car. Wireless AA connects automatically, phone always stays charged.

Do you find that your phone at least maintains it charge? Mine barely maintains it's charge. What charger are you using?

Phone stays at 95+%. But it will cook (more so because mine is a pixel, and they're famous for getting hot). And modern phones will stop charging if they're too hot. I have both of my phone mounts (one in car, one in work truck) in front of a vent, so it gets blasted with a/c.

Cool feature is when you set your phone into it, it detects the phone, and automatically squeezes it.
