I'm having a frustrating issue with my laptop where it automatically reduces its performance to save battery life. This is especially annoying during gaming sessions. The charging port has become loose over time, and it only charges if I adjust the cable just right, which can lead to it disconnecting while I'm playing. Once the charger is unplugged, my laptop goes into low performance mode and doesn't return to normal until I restart it. How can I force my laptop to stay in high-performance mode while running on battery?

Keep in mind that many laptops will throttle battery performance to protect the hardware, so there might be limits on how much performance you can get while unplugged. The primary concern is really that faulty charging port; get it sorted out first, and that should help with the performance issues too.
If you're on Windows, you can adjust the power settings to try to keep your laptop from throttling its performance on battery. Just head over to the power options and see if you can set a performance profile. Just keep in mind, many laptops, especially gaming ones, can't deliver their full power without being plugged in.
It sounds like your battery might not be strong enough to support high-performance tasks. Before looking for a fix, you should really address that loose charging port since that’s causing most of the trouble. Once that’s fixed, your performance should improve while gaming.

I’ve noticed similar issues on Linux systems, and it typically has similar power settings too. Just check your power manager!
