I've been dealing with the same drop-off issues on my Fold 7 and it basically comes down to the air gap created by the hinge. When it's closed, the phone sits at a slight angle on traditional stands, which causes the induction loop to break once the heat builds up. To fix this while keeping costs down, I suggest looking at a flat pad like the Samsung 15W Wireless Charger Single Pad EP-P2400. It eliminates the height variable entirely since you arent fighting gravity. If you really need that desk view, the iOttie iON Wireless Duo 15W Charging Stand works well because the fabric surface provides enough friction to stop the phone from sliding off the sweet spot. Honestly, check out the FCC ID search for the device if you want to see the actual internal coil layout. It shows exactly how low they're positioned this year. Knowing the internal geometry makes finding a match way easier.

In my experience with these dual-battery designs, the induction coil on the Fold 7 sits way lower than on standard slab phones. I've tested quite a few setups over the years and single-coil stands just wont cut it anymore because the hinge alignment throws off the centering. Those disconnects you're getting are likely due to the EPP handshake failing when the alignment is even slightly off. I moved over to the Anker 533 Wireless Charger 3-in-1 Stand 15W because it uses a triple-coil array. It basically eliminates that sweet-spot hunting. Technical tip: check if your wall brick supports PPS. If input voltage fluctuates, the Fold 7's controller is super sensitive and will kill the connection to protect the hardware. If you need a desk setup fast, the Mophie 15W Wireless Charging Stand with Adjustable Support is also great since you can manually slide the charging surface to match the Fold's lower coil position.

Unfortunately my old stands were overheating the battery. High hopes for my desk setup were ruined because the Z Fold 7 coil alignment is tricky. I tried the Spigen ArcField 15W Max Wireless Charger Stand but it felt unstable. Eventually I went with the Samsung 15W Wireless Charger Duo because it is way more reliable. Third-party stuff just isnt as safe for these expensive hinges honestly.

Unfortunately, the Fold 7 is proving to be a bit of a headache for charging efficiency. I ran some diagnostics and the thermal throttling is incredibly aggressive if the alignment is off by even a few millimeters. Its not as good as expected for a 7th gen device, tbh. The safety protocols kick in and kill the connection because the induction loop gets too hot from the air gap created by the hinge. If you're in a rush for Friday, these might actually hold a steady charge:

• Belkin BoostCharge Pro 15W Convertible Magnetic Wireless Charging Stand with Qi2
• The tilt mechanism lets you minimize that gap better than a fixed stand.
• Mophie 15W Universal Wireless Charging Stand
• It has a pretty wide induction field that seems to handle the Folds lower coil placement without dropping out. Just watch the heat. If the phone hits its thermal limit, itll stop pulling power to protect the battery cells. Let me know if you need the specific voltage logs for these.
