I just like this community and like talking with ppl about stuff and thangs. and this is my method to whitelist ppl! JIC U were already whitelisted. I know I didn't GA much but I like to. also I prefer to gift my game to who I like...

that's fine, or we wouldn't have many threads here. i just wanted to spam a gif :3

why not make the S into color? i know you can do it ;)

its bad for the future lifespan of the battery. if you leave any battery powered device plugged in charging all day, the battery life will diminish. I'm not totally sure why. I always unplug when my electronics are at about 85% charged. This might be why when you buy a new computer or phone it's never fully charged.
Additionally, you should never go to very low battery. Plug in at like 15%

I don't agree with the don't charge up to 100% as I think it's just a myth but I do think that you shouldn't let it go below 20%

Not a myth. Lithium batteries can be overcharged, so i is recommended to have them partially charged every so often.
Comment has been collapsed.
Well, when you say "it's recommended to have them partially charged every so often" because they can be overcharged, it's more reasonable and different than when people never charge their batteries up to 100% because of weird reasons provided by a fb page, also since most new laptops have that feature where they skip the battery after it's fully charged as you said in another comment, can it overcharge then?
Comment has been collapsed.
It can, because batteries are not as an exact matter like "hey, it reached this mV amount, it is 100% charged". The reason people advise to charge to 80-85% is to avoid this uncertainty.
By the way, the advice about not letting a lithium battery discharge completely is also accurate, but it just means that if you can, charge it when the phone/laptop says that you should (it is around 15% in most cases).
Comment has been collapsed.
Yep, as I said, I think it's always better to not let it go completely empty but I didn't know about the overcharging problems before, still 80-85% seems too much especially when you don't have a stable source of electricity, like I have at least 6-9 hours of no electricity a day that's why I try to charge devices as much as possible when electricity comes back on.
By the way, the heating problem seems logical as well, I think it does affect the battery life depending on previous experiences of mine, it might also be more important than worrying about how much charging the battery is getting in my opinion.

In those cases you need what the Africans do and have power banks, so you can keep the power of your devices even at the power outages. This is why some noname Chinese phone is popular in Middle Africa, it has a ridiculously large battery that can power other devices.

The percentage at which that notification is given can be set to any level on almost any device. 15% just seems to be the standard default.

Usually with a reason though, it seems to be one those "everybody agrees upon" numbers. Since batteries can be rather different despite using the same chemicals to store charge, I guess it was best to just use some good-sounding value. Like how structural engineers just tend gravitate to the safety factor of 2.0 regardless of building type or material.

It's not a myth. Modern smartphones give you a message to unplug them when the battery is more than 90% charged (and give you an info to plug them in when less 30%).
Hybrid and electric car batteries are not getting fully charged and discharged just to expend life time.

I'm not totally sure why
Because then your battery is basically discharging and charging at the same time, which increase the load. It should only charge OR discharge, not both, at any moment. That means you shouldn't use a computer when it is being charged as well.
This might be why when you buy a new computer or phone it's never fully charged
They are always fully charged before packaging. However, depending on how long they remain unsold, the battery power diminishes through time (even when not being used), so when you unbox a phone/table/laptop, the charge is often around 70-80%. The lower the charge, the longer the product was kept in storage.

as far as i know, the battery in your notebook is not even used when you have fully loaded it and get power over cable. it's not constantly charged and discharged. and i guess the same goes for smartphones etc.
Comment has been collapsed.
Only the newer models apply this method of current-controlled circuit. But even if it does not affect much the capacity of the battery, some smartphone batteries may get deformed if you use them constantly while charging: because the current is lower, it takes longer to fully charge, and also heats up the phone in the progress, causing the battery to swell up and eventually decrease its lifespan. Some extreme cases may happen to be explosive.
Comment has been collapsed.
You'd wish. Cheaper devices, and especially those of noname brands don't have that circuit, they just pass the current through the battery. This is why those cheap things have dead batteries in months or a year at most. (And sadly even corporate level laptops lacked this… my last company's laptop pool was essentially a set of computers you could carry from a wall socket to the next as the batteries couldn't last 20 minutes.)

I leave my laptop plugged in when possible. Although this is because I read online that with my type of battery it should be kept plugged in rather than let it discharge+charge.

It used to be a big problem with nickel batteries. The everyday term was that they lost their zero point, meaning the more they stayed at high charge, the lower you could charge them later.
With lithium ones it is not as bad, and most laptops have circuit design where it stops charging the battery and powers the laptop directly from the socket, skipping the battery.
The problem is that since you are not using the battery, you have a fully charged one that gets a lot of heat from the laptop, and that is bad. You remember how in heat waves your phone seems to die in mere hours? It's because lithium batteries really, really hate temperature. So, if you have your laptop plugged in all the time, remove the battery and keep it somewhere cool. Yes, it can mean the freezer. It actually does it good if you cool it below zero once in a while. (Same goes for phone battery. This is why it can be a good idea to buy a second battery and keep them rotated, one spending a little time in the fridge.)

thanks for info but the battery is not removable. laptop is Asus X554lj

luckily i got the broadwell cpu which has lower voltage and lower heat (yes, lower Ghz...). and SSD.
so almost no heat . the fan is off most of the time ;)
Comment has been collapsed.
The 15 W line can still generate a good amount of heat, they just like to set the BIOS to not turn on cooling until it hits near 60 degrees. So be a little careful: it may be slowly heating your battery without you realising it. Sadly, battery temp sensors are still not included, you have to buy them separately, but they can be a good indicator to know how even the low-wattage system heat is dissipated.

hmm, i might make the fan go on anyway in that case
it usually goes on after a long session and when working on something CPU intensive (while double monitoring)
Comment has been collapsed.
Check CPU temps with any kind of temperature sensor. If you can keep it in the 30s or low 40s, it is rather good for the system in general.

around 50C mostly...
no simple fix for starting the fan. i'll read later on more elaborate ones

Say, is using an underbelly fan effective in removing the excess heat? I use this fan which I place my laptop on top of: https://www.amazon.com/Cooler-Master-NotePal-Ultra-Slim-R9-NBC-XSLI-GP/dp/B005C31HC0

Eh, there is no definite answer. On some laptops it can help a lot (10+ degrees cooler), on some it is an expensive tray to put it on. Depends a lot on how the cooling of the laptop was designed. If it is something that wants to dissipate heat under it instead of a rear exhaust, it helps.
But sometimes a simple docking station that elevates it is cheaper and better. ^_^

Before you use a device like that, I suggest making sure that the inside of your laptop is dust-free. I have to clean mine about twice a year since dust builds up in the exhaust/radiator so much that it obstructs airflow, making the laptop run hotter in addition to the fan spinning faster.

So, if you have your laptop plugged in all the time, remove the battery and keep it somewhere cool.
This isn't such a good idea. While you might lose less battery capacity by keeping the battery in cold storage than by keeping it in the laptop all the time, you'll more than pay for it by the inconvenience this incurs. Specifically:
- you have to keep track of the battery charge so that it doesn't get too low and the battery dies;
- you can't use your laptop as a laptop, i.e. just take it and go somewhere--you have to plan to use the battery, because you have to wait for it to get to room temperature first, otherwise you run the risk of condensed water short-circuiting something;
- most importantly, a wonderful thing about battery-powered devices is that they have an integrated UPS. If you take the battery out of a laptop, then it no longer has a UPS, and you will lose work/progress and possibly have data corruption after the inevitable brownout/outage occurs.

I think it was depend on the laptop. My laptop will stop charging when it reach 80% battery capacity.

I'm electrical engineering student and I never cared about my laptop battery because it's really hard to obey the rules regarding keeping the battery. My battery is 9-cell and 4 years old. It deteriorated over years so that it can only charge to 25%.
About laptop temperatures? Not sure they can even harm the battery because firstly it's hard to keep laptop under 70 Celsius (if you're gaming) and I never noticed any heat dissipation from my battery or rise of the temperature because of electrical load applied to laptop (except when he's on battery only ofc)

I leave my laptop plugged in but with software set to only charge the battery up to 90%.

Hi, Is it OK if I put my laptop charger plugged all day? is it bad for the battery or charger lifespan? how much bad?
