Laptop battery life

[GunsForBucks]

Got a new laptop and am using it at home.

Is it better to unplug it and use the battery? I don't want to ruin battery life by keeping it plugged in constantly if that is an issue.

Thanks for any replies!

I would not advise to remove the laptop battery though. Simply due to how easy it can be to accidentally unplug the laptop and you don't want that happening during use. Yes look within the oem branded software (hp, lenovo, dell, asus, msi), it should have an option to limit the max charge % to help lower the overall wear and tear on the battery

Can't seem to find it in theOS setting and the HP stuff wants to connect to the internet

Thanks for the suggestion though

The OS doesn't have such a setting. Have to use the HP software that comes with the Laptop as this offers more advanced controls

If you are only using it at home then you can just remove the battery, if it is removable.

If they do that then the battery will slowly decay over time to be dead eventually. Lithium Ion batteries are currently the best we have for a battery technology but even Lithium-Ion batteries still have a (admittedly slow) self-discharge rate and must be re-charged periodically.

We can't remove a battery for a laptop and leave it out forever. The battery will end up flat dead and useless some day. It's better all around to just leave it in the laptop, and if we're home for a few hours leave it plugged in so the battery stays topped off.

Well topping off is probably not the best thing if they take more damage at 100 percent over time? I think someone said 100 percent bad


its gettingn late here

Keeping a battery at 100% is not bad. They were trying to mislead you with false information on purpose. I have a 2016 laptop and I keep it plugged into a charger when not using it to keep it topped off. Occasionally I grab it to go on a road trip or to mcdonalds and it's always ready to go when I need it and the battery still lasts the same 4 hours of runtime today that it did when I bought it new in 2016. The same with my phone. I have a 2018 model Samsung Galaxy S9+ phone. I bought it new in 2018. I commonly end up with it down about 30% battery at the end of the day. I always plug it in to charge when I go to sleep. It always charges to 100% (and stays there for many hours while I sleep). It still lasts all day for me on a full charge just like it did in 2018.

Charging modern batteries to 100% doesn't hurt anything.

They stop charging once they reach 100% and it's fine to charge it to 100% for the very first charge, but if you keep doing that it can reduce the lifespan of the battery by up to a year or more, which is a long time if you use it every day and want to use the device for as long as possible without having to deal with needing to replace parts, compared to only charging it up to ~90%. That's based on manufacturer data, those who are actually qualified to state such things.

It's bad to completely drain the battery, and it's not ideal to constantly keep Lithium-Ion batteries at 100% because you're unnecessarily robbing yourself of extra charge cycles.

This is completely false information. Read my comment above: It doesn't hurt anything to keep batteries at 100% all the time. It's perfectly fine with zero issues for many years.

All of the science supports the suggestions made by manufacturers; they all suggest that your minimise the amount of time that a battery spends at zero or full charge, as both are highly stressful and will reduce a battery's lifespan over time as it's continually done, and that partial charging is highly recommended to preserve it as much as possible. It won't kill your battery or completely destroy its lifespan in a short period of time but it reduces the overall lifespan, resulting in fewer charge cycles before the battery fails. You might get 10+ years out of a battery while charging it to 100% all of the time, easily, but you could also get up to a few more years out of it if you take precautions that are highly recommended by the experts.

I recommend ignoring the other person that repeatedly claims that I'm spreading misinformation without providing any actual proof when I'm only echoing what actual experts that design and manufacture these things have recommended. All they've been doing is following me around and trying to discredit me for the attention.

You can search in google and come up with as many random websites/articles/whatever that you want to. That doesn't make what you said right or correct. All you did just now is show everyone that you know how to search in google. You're still wrong with your comment. Did you actually read my comment above? If not then you should go read it. I have actual first-hand experience charging batteries to 100% for multiple years. Nothing negative happens. They still have the same run time and battery capacity as when I bought them new. Exactly like I said: Charging a battery to 100% DOES NOT HURT BATTERIES.

I sincerely hope you can ACTUALLY READ this time.

You're still attempting to spread false FUD and crap on the forums and pretending like whatever you say is the truth when you know it isn't. Fortunately for everyone I'm still here to make sure we all know the actual truth about your words.

Meanwhile over in the Steam Deck Dock discussions there is a guy stating that he has to replace HP Laptop batteries constantly, because they are kept at 100% charge.

the battery and destroy it in ~2+ years if constantly connected.

Namely HP docks are made like this, they are known to destroy their own Elitebook batteries in fact.

(working at IT, tons of ruined batteries from HP docks specifically goes through our hands on regular basis as an example)

I wanted to add to this conversation: Just like what Shaggin says. I have a 2014 laptop and I leave it plugged in to AC for multiple months at a time so it's always at 100% when I'm ready to use it again. Sometimes it sits there for a few months plugged into AC power and at 100% battery. Now it's been 10 years since I bought it new and it still runs just as long on battery when I need it as it did when it was new. Anyone claiming that keeping our batteries at 100% in laptops and other devices is just spreading Bull💩.

Post the make and model of the device so we can conduct research into the technology behind it.

Also, does the battery health indicator on the device indicate that it is still at 90% or above?

Dell XPS 13 from 2014. There is no external battery indicator but the windows battery % still shows it's at 100%. I just went out to the work room and powered it on to see. I routinely grab it and go take it around with me and often drain it to 30% to 20% and just go home and sit and plug it in. Battery always charges to 100% again. Nothing wrong. Nothing negative. Nothing wrong. It just works. All that useless crap about "BATTERIES DIE IF WE CHARGE THEM TO 100%" is complete Bull💩 like I said. It might shorten the life of a product if we do this, but this one has made it to a few months past 10 years and I don't see any negative effects yet. Most people will replace a laptop long before 10 years has come and gone anyway. Even if we do charge something to 100% battery, the battery will still outlast the "typical usable lifespan" of the device anyway.

Not charge level, the Health level. The Health level should never be at 100%.
