Dell XPS 9500 new battery. How to for first time use?

[UNIXNETWORK]

Hello, I need help, advice with new battery. I bought Dell XPS 9500 in perfect condition from outside and inside. Upgraded ram and nvme drive. But battery life is poor. So I purchased new oem battery too and replaced.

When I installed battery, windows showed 72% of battery remaining (I believe it is very good from warehouse). Then I charged battery 100%. And here I need your help, advice guys. How to use, calibrate battery for first time. Some says leave it on charge 24h, some charge 100% and use normal. This computer will be for my daughter and I'd mention to her how to keep battery lifespin longer.

Just plug and play. That's it.

 

For "calibration", I am not aware of any such option, but you might find something in the UEFI or one of the OEM's software.

 

As for keeping the longevity, first of all, I should mention that the myth of "overcharging" a battery when it is full is complete false, so you can keep it plugged in. In fact, you should keep it plugged in all the time whenever it is possible because laptop batteries are considered more like backups rather than primary source of power. In high performance laptops, the maximum amount of power that can be delivered to the whole computer system reduces if you run only through the battery and don't connect to external power. Also, it will be better to keep it charging slowly rather then unplugging it, draining power faster and recharging it again, which will reduce life span faster.

 

The only concern about articles telling not to keep your laptop plugged in is that the ideal range of charge your battery should contain should be between 20% to 80% of total charge for prolonging life span. My laptop's UEFI actually allows me to set a limit of charge capacity of my battery to prolong life span. See if your laptop also has such a feature, or there might be third party solutions for it.

Thanks for reply. I'll look into can I set to charge from 20% - 80%. As I know daughter dosn't play games on computer and no livestreaming videos. So most browsing web, watch videos and listen music and office. Nothing else what I know.

Dell Power Manager can be used to set charge limits, if that's something you want to do. I've got mine set up to not charge beyond 85% and not start charging til it's below 75%.
