Laptop with better performances on battery than while plugged in/charging
I am using a Dell G7 16 7630 laptop, and some days ago, I saw my computer was slower than it used to. I have searched on my side to know what it could be about, and I still have issues. Currently, I have a regular behaviour when I use my laptop on battery, but once I plug it in, with the original charger, I have a drastic performance decrease, and abnormal overheat, and loud fans. I noted this informations if it helps, while plugged in and game was running, from Hwinfo64 :
CPU Package Temperature : 100°C
Core Effectice Clocks : 300MHz
Thermal Throttling : Yes
Package/Ring Power Limit Exceed : No
CPU Package Power : 26W
GPU Utilization : 17%
GPU Clock : 630MHz
GPU Power : 16W
Processor: 13th Gen Intel(R) Core(TM) i7-13650HX
RAM: 32.0 GB
Graphic Card : NVIDIA GeForce RTX 4060 Laptop GPU
I also noticed the GPU use went from ~50% when on battery to 25% while charging.
I could easily watch a YouTube video while play games on battery, and both have really low framerates when I plug in my laptop.
I'm really lost to why it happens this way, so I come here to ask some help about that situation
