I'm buying a new laptop and looking to know what the best method of maintaining battery life.

I've done fairly well with my current iPhone by keeping it between 20% and 80%, after 2 years of everyday use its still at 95% capacity.

Any examples of how much time your laptop battery provides after a few years?
 
There isn't much you can do really to preserve the longer term battery life other than limiting charging to 80% and making sure it doesn't sit at discharged levels, etc. with a periodic charge (~4-6 months) to at-least 70% if not in use and so on. Along with avoiding temperature extremes if possible.

Most modern laptops have battery management software enabling 60,80,100% charging before switching charging off. I have an LG Gram and set to 80%, then get about 7-8 hours of general use out of it before needing a recharge at 20%. Drops down when I start doing development, but generally sat at a desk then so powered

Do Dell laptops have this?

Lenovo laptops are fantastic, can charge to 60% and then just run off the wall power.

That sounds terrible! What if you're somewhere without mains power and you've only got 60% battery to use?

Realistically just like phones battery health trends to also degrade with quick charging, so the idea is to get to a certain %age and then trickle charge it whilst still plugged in.

The absolute best thing you could do is to remove the battery (if that's still possible), but does then beg the question of why did you buy a laptop.

Then you disable conservative battery mode to allow it to charge to 100% and if you're in a rush enable Rapid Charge. Mine came with a 300w brick, doesn't take long at all.

Well I went for the Acer Nitro 5, purely for the specs and cost, 12500h / 3060.

It includes battery manegement as part of its Acer Care app. Which allows the battery to charge up to 80%, but charging is very slow.

The noise from the fans has turned out to be more of pain, even when idling.

Could be Windows 10/11 doing stuff in the background - my devices on 10 tend to start doing background maintenance, etc. if the laptop has been idle >15 minutes which then causes the fans to spin up a bit :( there is also a common bug with many laptop systems where the memory checking process bugs out and never completes - just sits there with the system process using 100% of one core indefinitely until you move the mouse/press a key or sometimes even bugs out completely and never stops until you reboot.
