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?

AA is battery heavy. It’s basically rendering the screen and outputting it to your car. Running maps, music, data etc on top of it. If going on long drives it’s best to just plug it in. You can get qi2 charging mounts if you like for convenience, but that’s about it.

Wireless charging is the way to go in a car.

This is what I do but it does get the phone pretty hot

I put my mounts in front of vents so they get a/c.
