I've noticed something odd with my MSI GF66 laptop. When I remove the battery and connect my phone via USB-C, it shows that it will take about 2.5 hours to charge. But when I put the battery back in, that charging time jumps to 7.5 hours! My laptop is plugged into its power adapter, so I'm confused about why this is happening. Does anyone know why the charging rates change like that?

The reason you see these different charging times is all about power distribution. Your laptop adapter provides a set amount of watts. When your battery is in, the laptop's power management may limit power to the USB ports to prioritize system functions and the battery charging. Without the battery, more power goes directly to charging your phone. If your adapter has a higher watt rating, it could help improve things, but for now, it seems like your laptop is simply allocating power more efficiently when the battery isn’t involved. You could also try lowering settings like brightness to see if it makes a difference!
That makes sense! My adapter is rated at 180 watts, and I’ve checked that the battery is fully charged. It's weird that it happens even in BIOS too; I figured that wouldn’t be a heavy load.
