Possible way to increase battery life?

[jfehrle]

I've had my Omen laptop for almost 5 years now.  I've noticed that the battery life has gotten much shorter over time.  99% of the time the laptop is on my desk and plugged in to the charger.  My understanding is that lithium batteries last longer if they're close to fully discharged before they are charged again or are charged slowly.  (For example: my Pixel 7a phone charges slowly overnight if the phone is left on and the alarm clock is set. Otherwise it charges quickly.)

Is it possible to extend battery life in future products by giving software more control over charging?  For example, having a setting that lets the battery discharge to, say, 50% even with the charger attached before beginning to recharge?  I could use this setting while I'm at my desk and then turn it off shortly before I plan to travel with the laptop.

"My understanding is that lithium batteries last longer if they're close to fully discharged "

That was with the old school NiMH batteries.

With Lithium Ion batteries, they should not be discharged to below 20%.

To extend battery life just don't charge them to 100%. HP suggests not charging them beyond 80%. Use the Battery Care option in the BIOS to set this charge limit. An Omen laptop is top tier and likely has that option in the BIOS.

At five years it is time to replace the battery with a new one before problems began to show up.

I suggest invoking and running the Windows Battery Report utility.

See the article at the link below. I described how to invoke and use the utility.

It will let you see how many cycles the battery has been through.

It will also show how vast the difference is between the design storage capacity and the current maximum storage capacity.

It is the best way to get the big picture on how much service life your battery has left.
