uBlock Origin is not simply an ad blocker as many might assume, rather it is a powerful content filter, similar to a firewall, that is capable of both dynamic and static filtering. In addition to blocking annoying content such as ads, it can also block JavaScript, frames, images, 3rd party fonts and more, as well as help to prevent tracking and malware.

There are various similar guides on other sites, but many of these guides were partially incomplete, so I’ve tried to write the most complete guide as possible, which can be used by paranoid users like me.

In the XPS 15 9530, there are options in the BIOS to manage battery charging. I believe the default is Adaptive and there are some other pre-defined profiles, but if you choose Custom you can specify a bleep to limit max charge. You can also specify a minimum charge that the battery has to self-discharge to before the system will start charging it again -- so for example if you set your max charge to 80% and your minimum charge to 50%, then once the battery reaches 80%, the system will continue to run on AC power, but it will NOT keep the battery topped up. Instead, the battery will be allowed to self-discharge down to 50%, which normally takes a few days, and only then will the system charge it back up to 80%. This increases battery longevity, as long as you can deal with the potential inconvenience of only having a 50% charge available when you disconnect from the wall.
