Determined the issue...and it is an issue with the current iteration of the SnapCharge. It maxes out at 7.5w so, while that will activate MagSafe for older models, it's insufficient for the newer models like the 16 line.


I've asked about a timeline for an upgraded model, but they, apparently, haven't started development on a higher wattage charger, just yet so, for now, I'll have to stick with Apple's charging pucks or find another option.

Update: we took my wife’s phone to the Genius Bar yesterday. The very helpful associate ran some diagnostics that revealed a normally functioning battery. He suspected a third party app may have corrupted the software, and scheduled us for a wipe and reset the next day, as we needed to wait for my wife’s messages to backup. He would then walk us through downloading only proprietary apps from the cloud, meaning my wife would have to manually reinstall other third party apps. We were willing to try this, despite the tedious process ahead, to determine if the phone was a dud, as we are still within T-Mobile’s 14 day return window. He also suggested we try one of Apple’s MagSafe pucks (which my wife was going to buy for work anyway), to see how the phone charged on it.

This morning, we woke up to her phone fully charged on Apple’s puck, while my phone — which previously had no issues on my Anker 3-in-1 or my wife’s Anker 3-in-1, was not fully charged. Is there a “pulling out my hair in frustration” emoji?

This makes me think we’re dealing with a software issue. Perhaps Apple hasn’t fine-tuned the new battery management features well enough so that phones running iOS 18 play nicely with other MagSafe chargers? We’re going to keep the appointment, just to get our new experiences on file. I’m confident that if Apple has enough documentation of the problem then they’ll find a way to fix it… hopefully.

I'm having similar issues. When I first got my 16 Pro, it would charge on the OhSnap! Snap Charge, the Apple Magsafe charger and a Magsafe battery pack.


I had it in an ESR magsafe case, an OhSnap! Snapcase with the SnapGrip Luxe.


After a recent update (18.1? 18.1.1?), my phone will still wirelessly charge on Snap Charge devices but no longer magsafe charges on them...with or without a case or the grip. My old 14 Pro magsafe charges on these devices just fine.


I've had all of the chargers plugged into the same different power sources:


Apple 20w

Apple 30w

Rosonway multiport, powered USB dock

Macbook Air USB C port


But magsafe charging on the OhSnap! Snap Charge no longer engages magsafe charging on my 16 Pro.

My wife is having a similar issue with her new iPhone 16 Pro. It will not charge on her Anker 3-in-1 MagSafe unit, even though the phone says it’s charging. We’ve tried without a case and two different MagSafe cases, with no luck. My iPhone 16 Pro works on her charger with no issues. Apple support had us restart the device and then do a hard reset. It seemed to resolve the issue at that moment but last night it failed to reach the 80% limit again. It charges as it should via the cable, and seems to hold the charge it has as it should. It just won’t top up with MagSafe. Will be contacting support again soon.

New Apple MagSafe chargers use the Qi 2 standard which doubles the output to 15 watts. The older chargers are probably Qi first gen and only 7.5 watts. Double the wattage, double the speed. However, fast charging requires 20 watts or more, if I remember correctly.

Fast charging with a MagSafe puck requires a 30 watt power source. Thus demonstrating that wireless charging has only 50% efficiency, and thus is not “green”. And it also means it will cause the heat generated during charging to be much higher.

It depends on whether or not I have anything else plugged into the block (an Anker Nano65), which has two USB-C ports and one USB-A. According to Anker, using a single-C port gets 65w. Using both -C ports gives a 45w/20w split. Using one -C and the -A does 40w/22.5w. I rarely use all three ports, but that’s supposed to split 40w/12w/12w. To clarify, my wife and I EACH have our own set-up (the Nano block and an Anker MagGo 3-in-1). We’re not charging both our iPhone 16 Pros from the same charger.

I know and have that Anker charger, and it can be a little flakey. On older models the 2 C ports are labeled with different current capabilities, look at yours. Also, when you connect an additional device the whole thing resets, disconnects and (usually but not always) reconnects all devices. As a real test get a single 30 watt USB-C power source.
