iPhone 15 Pro Max not charging with 5W Apple charger

I am using the Apple 5W charger with a UGREEN USB A to USB C cable and my iPhone will charge for a couple of minutes, and then just stop. When I use an Apple 10W charger, it works but I would like to charge it more slowly. I want to use a slower charger to charge my phone overnight to preserve the battery.

iPhone 15 Pro Max, iOS 17

well they stopped selling 5watt chargers, so maybe newer phones requires a higher current before it triggers the charging system


charging it with a lower watt overnight will not be better for the battery

It stands to reason that lowering the wattage at which you charge your phone will be better for the battery by limiting the heat generated while charging.


“A battery warms up as it charges, which can reduce its lifespan. To reduce the effect of heat and prevent overheating, iPhone gradually reduces the charging current as the battery approaches full charge.”

Maybe the benefit is not noticeable within the first year or so, but I would imagine this small change would have a greater effect over 1000+ charging cycles. Apple claims the battery in 15th gen phones should still have 80% health after 1000 charging cycles. This ends up being about 3 years of one charge a day… right when they want you to upgrade?


@mrleaw have you found a charging set up that works at 5W?
