There are many hacks you can use to protect your cables and ports. But while you are speaking about notebook probably you do not want to carry more stuff

You could attatch a glue-on cable clip to the laptop and secure the cable in it.
Something like this:
The clip's inner diameter should be the size of the power cable so it sits tightly. That way the power plug always sits in one direction and pulls on the cable are partly dampened by the cable clip.

Use the polarizing filter of the monitor itself.
I suggest trying the following with an old laptop or LCD monitor first.
After dismantling, remove the outer layer from the monitor. Now the monitor is completely blank, and whatever is displayed invisible to the naked eye.

Cell phone batteries (and everything else nowadays) uses Lithium Ion batteries. Unlike previous generations, these don't have a "memory" effect, so there's no need to completely discharge them all the way and then recharge them. In fact, frequently adding small amounts of charge (like taking it on and off a wireless charger) is a recommended use case.
A variant of the quilters plastic template suggested by @holroy : punched pocket, the one which are a bit rough or "granular". It's kind of a quick/cheap fix because there is some color issue on white background (cf the picture below) but, still it does a great anti-glare job.
