This Lenovo Legion Slim 7 15 Gaming Laptop, Content Creator's Configuration, model number 82K80081US, ships with a Integrated 71Wh, Lithium-Polymer Battery, which within this configuration, has a battery life of up to 6 hours, depending on the work the device is performing. To maximize battery life, try setting your Power Management to Hybrid within the Lenovo Legion Vantage Dashboard, installed on this computer. Additionally, if you are getting substantially less battery life, first, set your screen brightness at less than 100-percent - try 80-percent to start with. Then, be sure Battery conservation Mode is turned off. This power management setting should only be used when the laptop is plugged in all the time. It will prolong overall battery life by only charging the battery to 60-percent of capacity. Here is a link to instructions for turning off Battery Conservation Mode: https://support.lenovo.com/us/en/solutions/ht103159. Also check what programs are running in the background on the computer.

The software is already part of the operating system, you just need to activate the software with a purchased product key. If you have installed a copy of Microsoft Office, this is conflicting with the existing copy on the system and this will slow your system down. If you have installed a 3rd party anti-virus program, be sure that Windows Defender is turned off and that the trial version of McAfee Anti-Virus software is uninstalled. There can only be one anti-virus program on the system. You may need to restore your system to original factory default settings if any of the programming errors have occurred. You can do that by typing "restore" in the Cortana search window. Just click on the magnifying glass icon at the bottom of your Windows 11 Desktop. Click on "Reset This PC" Then click on "Get Started" and follow the on screen directions to restore to factory defaults.
