iPhone SE (2022) Charges Faster With MacBook Than USB Adaptor?

[Christopher11]

It may be my imagination friends, but it seems to me my SE 2020 charges faster connected to my MB Pro than if I plug it to a cube from the wall. Have you noticed this? Maybe because it's USB C to lightning from the MB?

Not all cubes are created equally.

Ah. I've noticed when I charge at work it literally loses battery... so that's a losing proposition. Something to do with the power there I guess.

USB-C from MacBook is 15W

Even back in 2015/2016, I used my MacBook Air to recharge my phone cause it’s genuinely faster than using any wall plug. It’s 10W versus under 5W despite using the same USB2 cable. Apple has long tweaked their MacBook to give more than standard power sometimes to recharge your device without tipping into “120W superspeed” territory.

The USB-A small charger cubes that Apple used to ship with iPhones deliver 5 watts of power. A USB-C/Thunderbolt port on a MacBook can provide up to 15 watts of power. The iPhone SE 2nd Gen/2020 can accept charging up to 18 watts (and supports quick charging), so it can take advantage of the increased power provided by the MacBook. Since you specifically said "cube" I'm assuming you're using the old USB-A charger so that's the difference.

If you pick up a newer USB-C charger it will actually charge your phone slightly faster than the MacBook but not by a huge amount.

Great info, thank you guys. I didn't know about the USB C cube. I wonder if anyone makes anything like it for the vehicle: to plug into the cig lighter.

Exactly, Macs have been giving iOS devices extra power for years (without USB-C cables). You can see it in the USB section in System Information when a device is connected.
