What charge limit do you use on your laptop?

[AJ29]

Some laptops let you set a maximum charge, often around 80%, though the setting depends on the model. A lower limit can reduce time spent at full charge if the laptop stays plugged in, but leaves less battery for when you take it out.

If you use a charge limit, what percentage works for you? Do you change it before travelling, or leave it set?

100%... usually by the time the battery is degraded enough to need changing I can source a half decent quality, compatible battey for undre £50 and change it myself.
I usually purchase 2nd hand laptops anyway, ex corporate machines offer a great deal of value and often end up replacing the battery on these.

At home, an 80% limit makes sense to me because the charger is always nearby. Before travelling, I’d charge to 100%—you never really know how much battery you’ll need on the road.

Power-saving mode is also worth using. In my experience, it can add a couple of hours of battery life, although that depends on what you’re doing.

I’d use the charge limit when it’s convenient, then allow a full charge when the extra runtime matters.

I mostly leave mine at 80% and only bump to 100% the night before a trip. One thing worth checking is whether your laptop’s limit resets after firmware updates or has a calibration cycle; if it does, you may occasionally see it sit at 100% even with the limit on. For a plugged-in desk machine, 80% is a decent compromise; for a travel day, I’d take the full charge and not worry about the extra wear.
