Hm. I have a similar issue. iPhone 12 Pro Max, new in January. Rebooting the phone seems to work temporarily to get the thing charging. At first I thought the phone is killing the chargers, but the waters are a bit muddied by the fact that an older wireless charger I was using with my iPhone X was getting glitchy even with the X, and wouldn't work with the 12 at all. So I got a Chinese Qi charger, four-way (phone, Pencil, watch and earbud). That one worked for one night, then quit on the phone charger (charge indicator light rapid-flashing blue/green, phone not charging). So I sent that one back, found a different one (Qi 3-way, phone watch and earbud) - same thing happened. At first I thought maybe the case was an issue, so tried without - and at first it worked, but not for a full night. Found the phone at 50% in the morning, blue/green flashing as before, with the other unit. Bought an Apple mag-safe, basic silicone case - no difference. On this charger, though, the earbud charger would charge the phone, if I laid the phone on it carefully, in just the right place, and charge it to full overnight. Weeks later, though, that stopped too. Completely annoyed, I decided to get a good, Apple approved Mag-Safe charger. Ordered the Belkin BOOST↑CHARGE™ PRO
3-in-1 Wireless Charger with MagSafe 15W ($150 - gulp!), which is scheduled to ship in mid-March -- so I guess we'll see. Meanwhile, a few days ago, the phone simultaneously stopped charging on the Qi charger on my night-table AND the wireless Qi charger in my car -- which had worked flawlessly the whole time. Both gave no sign that they had ever seen or heard of a "phone". My first thought was "my phone is a serial murderer of wireless chargers!". (I wondered if it would be safe to report this to the police using the phone - didn't seem a wise move.) Then I read your post, and went "Doh!" - I should know by now that when a thing with silicon chips stops working the way you expect it to, you first turn it off and back on again. I did (rebooted the phone), and the car charger, low and behold, started working again. NOT, however the Qi 3-way on my night-table, although it did go back to doing the blue/green rapid-flash thing, and charging the phone on the wireless earbud charger. All the Qi chargers have claimed they are compatible with the iPhone 12 Pro Max. So. Clearly there are multiple issues, or at least two, anyhow. The phone needing to reboot to work with a Qi compliant charger is one, and Qi chargers claiming they work with the 12 Pro Max and failing miserably. At this point I'm resigned to waiting until the Belkin purpose-built Mag-Safe, Apple-approved unit arrives; there will be more data to look at then, if nothing else. For your information, the Qi charger on my night-table is this one, listed on Amazon:
