My 22 wireless charges my Pixel 7 with no issues. Have you tried another phone to see if it charges? Have you wirelessly charged the 7a on another charger?I just got a 2023 and the wireless charging is useless.
I installed an app called Ampere to monitor charge/discharge.
I have a Pixel 7a and an Otterbox Commuter case.
When I put my phone on (29% charge), the display on the truck shows the battery charging icon, but Ampere shows "Not charging" and a negative current flow. With or without the case on the phone.
Trash.
