My laptop's performance drops when AC is unplugged

[Its_the_Elox]

Hi, i have a Asus laptop with intel Uhd graphics, performance is epic when its plugged in but when its unplugged the performance goes too rock bottom i get 30 fps and lower can someone explain why its happening and how i can disable the feature if theres any

It will always drop in performance when running on just battery. The battery can't provide the same performance as being hard plugged in.

You can get it to work, but then battery wont hold long.
and rule is you dont play games then unplug from grid or charge up.
other sugesstion you dont edit that battery mode that day you need it, and start laptop up with no power in the house to be done with some papir or work you actual have a battery mode that dont drain it with few minutes.

again this is your problem in what to do, but other laptop owner learn this to late then save as much juice as possible for emergency work.

That's literally working as intended. Batteries cannot do what you want a full power supply for.

[AustrAlien2010]

That's your power scheme that makes your hardware run slower to save battery power. You can possibly configure the power scheme to not do that, but then your battery goes empty much quicker.

Windows is switching power plans from getting unplugged or plugged, but you can edit these settings from the command panel. If that won't work, maybe your BIOS may also have additional settings.

This is entirely normal

Your laptop has different power modes depending if it is plugged in or unplugged. When plugged it will generally be in 'performance' mode where your CPU will be maxed out as well as making other things like brightness higher and your screen timeouts longer

When unplugged, the laptop will go into power saving mode. Generally this will lower the CPU max speed to perserve power, it will also decrease the brightness and aggressively power off your hard drives/monitors to save power

You can force high performance mode on your laptop when plugged in by going to the power settings. However note this will dramatically impact your battery life

[GOD RAYS ON ULTRA™]

Turn off battery boost. Although I recommend against doing that. But that's how you get it to perform better when using the battery.

Set Windows Power settings to High Performance, both while on AC and Battery
But as mentioned, doing so will drastically drain the battery when off AC

again as previously mentioned, when on battery its Normal for performance to drop to help lessen the drain on the battery, if the battery draining quicker isnt an issue for you then simply do what myself and others suggested.

Your battery would last 30 minutes running games unplugged

One of my friends has this other laptop Lenovo Yoga with intel Iris Plus Graphics and performance is good when its plugged in and when i unplug it the performance does not drop at all but battery-wise it goes down alot

[Cathulhu]

Because his laptop does not use that much power with just an integrated videochip compared to a laptop with a dedicated videocard.
Depending on the hardware used, the battery simply can not provide enough power to run the hardware at full performance.

[Du4lity (they/them)]

It's normal, since laptops are meant to slow down when you unplug them to save battery life. When your laptop is plugged in, it will know that it is getting more power, and thus will try to put more processing power into whatever demanding task it is doing. I'd suggest keeping your laptop plugged in whenever you can for optimal performance. If you have to unplug it, make sure it is at 100% battery.
