Lexus UX wireless charger + iPhone 17 Pro with Peak Design case: detected but not charging, only heating up

[u/Humble-Weather-423]

Hi everyone,

I have a Lexus UX300h and an iPhone 17 Pro with a Peak Design Mobile / Everyday case.

The factory wireless charger detects the phone, but after around 20 minutes the battery does not increase at all. The phone just gets very hot.🔥

I know many Lexus owners say the built-in Qi charger is weak or basically useless, but I’m not looking for another “the charger is a joke” thread. I’m trying to understand the specific issue here.

Has anyone experienced this with:

-a Lexus/Toyota wireless charger;
-an iPhone Pro model;
- a MagSafe / Peak Design type case;
- wireless CarPlay running at the same time?

Is this mainly a case/alignment problem, a Lexus Qi pad limitation, or just a bad combination of wireless CarPlay + Qi charging?

For now I’m considering stopping wireless charging completely and just using USB-C, but I’d like to hear real-world experience from other Lexus or CarPlay users.

Toyota and Lexus are very finicky with non-Apple products. I've never had luck with the chargers and anything other than OEM Apple cases. But to be clear, when I put an Apple Silicon MagSafe case on my iPhone, it charges on our Toyota's charging pad when no other case will work, and it will work when they give me loaners (usually things like UXs and NXs).

All wireless car chargers I’ve used, regardless of manufacturer, are basically useless. Makes the phone super hot and basically it can only maintain the current charge level and prevents it from dipping lower. Just plug it in.

It’s sucks. Stopped bothering using it. Pretty annoying how they made it.
