As for some battery basics to keep in mind if you don't have any fancy software or BIOS options, it's generally recommended to keep your battery somewhere between a 40% and 80% charge and to keep it cool whenever possible. Changing the settings to balanced on battery mode usually gets me a little over 4. I do not lose any performance on battery mode with mine because of how I have my settings, but the battery will be drained in a little over an hour of heavy gaming that way. If you have a laptop from another major manufacturer and are unsure if it has a battery charge threshold feature, you can always check with the corresponding support forums or go with a quick web search. If you want more battery life you can do the exact opposite with all of those settings.

If you boot into BIOS on your HP laptop and don't see the feature, your PC might not be one of the lucky ones to have it, especially if the BIOS is completely up to date. Some HP laptops, depending on the make and BIOS version, have a Battery Care setting that can be tweaked to limit the battery's charge. The process of enabling the Battery Limit settings requires a boot into UEFI, which is explained in a Microsoft instructional. Older devices might require a specific firmware update, available from Microsoft. It's instead available through UEFI settings, which come standard in new Surface devices like the Laptop 3 and Pro 7. Features Charger for lead-acid batteries (flooded, Gel and AGM) and li-ion batteries (lithium iron and lithium manganese) 2/3/8 stage charging selectable on. Most Surface products can be configured with a battery charge limit, though it's not quite as easy as opening an app.
