How to set Battery Charging Threshold

[Suffolk20]

It is well known that lithium batteries when charged above 80% get damaged slowly over time. I often use my laptop for long periods of time whilst plugged in and the battery stays at 100%.

Please could you find a solution for me that allows my laptop to stay plugged in and the battery charge to remain at 80% or a user defined percentage.

I do not think it is acceptable for you to say "it is ok for the battery to stay at 100%" unless you are willing to replace my battery for free if the battery doesn't hold a 70% charge after 8 years. Which is a standard guarantee for lithium batteries in cars.

Welcome to HP support community.

The adapter supplied by HP is a Smart adapter, which means it stops charging the device once it reaches 100% when the batter discharges to 95.5% it starts charging again, the 0.5% discharge is not showing in your device which is why we don't see it happening, however, that's how it works in the background.

I hope that helps.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.

Do you mean 99.5% as you mentioned 0.5%?

How long does it take the battery to discharge 0.5%?

Is my laptop going through 100's or 1,000's of battery cycles in the 8 hour period that I am using it?

Batteries have a finite amount of charging cycles they can go through. Is it better for me to keep unplugging my laptop when the battery is full and charge it back up 2 or 3 times a day or let it go through 1,000's of very small charging cycles when the battery is being stressed at 100%?

Really WE as your customers need you to develop a battery management program that solves this issue just while the computer is turned on (I can see the closed kernal would be an issue for battery managment while the computer is off).

Please can you elevate this to your management team so your company can start doing something about this rather than just being very polite and not solving anything.

Thank you for your well intentioned reply.

when I said "1,000's of very small charging cycles when the battery is being stressed at 100%?"

I meant to say "when the battery is being stressed above 80%?"

@Suffolk20

Lol, yeah that's what I meant, 99.5%
That said, the battery does have 1000 charges, more details would be listed under HP support assistant's battery check.

And as I mentioned earlier, there's no fix for this as this is not an issue, the adapter doesn't charge you more than what's required, nevertheless, I have forwarded your concern to the R&D team, and they may release an update on the same, however, there's no time frame I can provide.

Thank you for your reply,

Due to a resolution not being found I can't close this post, I feel it would benefit others more if I leave it open so they can comment too, as I originally wanted to add to someone else's post asking the same question 3 years ago and couldn't.

Due to this problem not being sorted in the last 3 years I feel you are just going to forget people asking for this. I'm within 30 days of purchasing my laptop, my decision now is whether send it back for a full refund and build a pc instead.

@Suffolk20

If the device is within 30 days of purchase you could get a replacement, however, as mentioned this isn't an issue as the smart adapters are designed to charge the device that said, the case will remain open and people can contribute to this thread for over an year before its locked.

Cheers

I bought the laptop in the UK from a shop that offers full refunds on any purchase for 30 days as per European law. You really have not understood my problem if you keep mentioning chargers that charge a lithium ion battery over 80%. It is not smart enough to maintain my battery at my desired charge level. I have decided that there is no point spending extra money on the convenience of a laptop if that convenience fails after a couple of years.

Thank you for your help.
