If a laptop battery is 100% charged, should I run it on battery power or AC mains supply?

You need not to run it on AC mains supply unless you're planning to go somewhere after charging that you need to conserve battery.

If you really aren't going somewhere else, then remove the charger and use your laptop on battery power. When it'll reach something like 8%-15%, then reconnect the charger and charge till it's 90&+.

Overcharging: In general, many of us charge our phones, laptops and other electronics till they reach their 100%. This is actually not necessary. Anything like 90%+ is enough. When you charge your electronic beyond 100%, it'll get into overcharging state. Due to flow of electric currents in battery, the battery's health tends to get weaker and weaker the more number of time and duration you overcharge it. This seriously damages battery either it be normal or even the one with overcharging protection.

Overcharging protection does help in protecting battery getting overcharged to some extent but your laziness will even destroy that layer of protection!

Here are the few tips from my side to help you protect your battery:

  1. Never charge your battery to 100%. Even 99% is enough. As I mentioned earlier, anything between 90& to 99% is good.

  2. Charge your laptop only when the battery percentage decreases to 20%. I charge when I get a warning of 6% battery.

  3. Never put your laptop always charging. Let it take some rest. Even full drained battery is essential once a month.

  4. Always restart your laptop once a week. I didn't believed this until I tried myself. This helps in resetting RAM.

  5. Always use original charger for your laptop. Don't use any cheap charger to save few bucks. Don't charge if you don't want to buy original charger.

  6. Always use stabilized electricity for your laptop. High or unstable voltage tend to harm display and battery.

  7. If you have a Lenovo or Dell brand laptop, then enable the 'charge till' option in your laptop. In Lenovo, you can use 'Optimized Battery Health' in pre-installed power management software. Don't know about other brands. Maybe try installing some software if it really helps.

  8. Use Windows Power Options according to your need to save power. Let it put your Laptop on standby after some duration of laptop being unused.
