Android phone "charging slowly": How to make it faster When I put my Android device to charge, the lock screen says "Charging slowly":



Is it a particular software setting that tells Android to charge slowly?

How to make Android charge fast?
This is not a software setting: Android is just telling you that the power source you connected the device to is not giving enough electrical power to charge as fast as it could.

It seems that:


"Charging slowly" means below 1A (at 5V),
"Charging" means between 1A and 1.5A,
"Charging rapidly" means more than 1.5A.


The solution is to make more electrical power come to your device:


If your computer has Type C port, use this one. This port will most likely also have Power Delivery, which will give you a "rapid" charge.
Plug to the wall rather than to a laptop.
Try different USB cables.
Some adapter/device combinations are better than others (example for Nexus 6P/5X), so use an adapter made specifically for your device if available.
Some laptops have different USB ports with different power performances. On my laptop I have 2 USB ports, if I plug in the port on the right Android says "Charging slowly" but if I plug in the port on the left (with the + battery symbol) Android says "Charging", which is better:




Edit: Please see @beeshyams' answer explaining why charging slowly is actually a good thing when your battery is already quite full.
