What's the point of having a popping cpu/gpu, screen and 12 gb of ram if it's fucking off :guaido-despair:
PLEASE do what the Chinese phones does and shove batteries down my throat
That’s not true anymore, you can have good performance under 15W. Power consumption is one of the only metrics CPUs have majorly improved on in the last decade. It’s just that batteries have shrunk accordingly to maintain that “8hr all day battery life”.
That’s true but you can still do a lot with just 15W. I realize they’re not directly comparable due to differing CPU architectures, OS overhead, and power optimization of the SoC, but the Nintendo Switch uses less than 15W and can pump out decent graphics. It shouldn’t be a big ask for similar performance in a 25W envelope on x86_64.
Oh for sure, you can definitely game just fine a 15W GPU. However those aren't the ones usually referred to as "popping". Also the battery life on those ones are probably fine.
Hello I would like to introduce you to my old thinkpads with removeable hot-swappable batteries.
My favorite kind of laptop battery is the one that renders you sterile if you keep it in your lap for more than twenty minutes
my laptop computer is essentially a luggable PC with like 2 minutes of reserve power if it gets unplugged, it's great
I have a chuwi herobook and a Huawei mate 20 light phone and they rule and I get to tell people that the government put sanctions on my phone maker.
Tech illiterate buyers know that if the ram number go up then laptop more gooder
Larger battery means the laptop is heavier which is bad right?
The design choices are all optimized for making sales to people who have a weak grasp on what they need in a laptop and not for the long term usability of the laptop.
Just like with phones, it's an issue with the constant need to one up each other with thinner and thinner devices in the name of portability.
If I can't use my laptop for weight training exercises then it has an insufficient amount if excess battery power.
If you can stand the idea of only charging your laptop to roughly 85%, then I highly recommend trying that. I've had my laptop for like 3 years now and haven't noticed any decrease in battery life. I'm also a huge stickler about brightness, and programs running in the background. With laptops being so power efficient anyways, I can still get a good day's use out of 85% anyways, and that's only going to get better with time.
I'm planning on doing this with my next phone, and other lithium ion stuff I own too.
Yes, from a chemistry perspective this is because the lithium ions in the battery basically work by moving ions between the lithium and other cells inside the battery, which powers the laptop, then by charging it it moves the ions back to the other side. However, overcharging or letting it get too low can cause buildups of some free ions (pretty sure) that severely hamper the ability of the lithium ions to return, decreasing the battery life. Lithium is the best material for the job as it loves donating ions to the anode (I think, might be cathode) since it’s unstable, but research is being done into sodium batteries as they’re extremely environmentally friendly and they don’t explode, although they’re orders of magnitude less efficient.
Wouldn’t this this be taken into account by a competent OS/whoever is in charge of telling the computer about the status of the battery? That is, if 30-85% were the optimal range, I would simply force the computer to operate in those ranges; go dead at 30% for example (and calibrate the battery life display accordingly).
Certainly the lower limit is limited, maybe not the upper limit. At least, my dumb e-cigs know not to discharge 18650s (which I believe were pretty common a few years ago in laptop battery packs) below 3.0V, although my charger is not smart enough to keep it below 4V or anything.
I guess you would need to lower on “x hour” battery claims if you did this, which is probably not desirable. And stuff isn’t really built to last.
So I guess I’ve talked myself out of believing this could ever be a native manufacturer/OS thing.
Lenovo has an option to only charge your laptop to a specified maximum percentage in the Lenovo Vantage program. I think other manufacturers are starting to implement this as well. I'm not sure how this could be done on Linux, but if there's a driver for the power management firmware it should be possible.
Laptops marketed as "ultra portable" or similar tend to have better battery life, but it's a trade off for less processing power. I prefer that sort of set-up because there's really nothing I'm doing on the go that needs a powerful GPU and 12GB of RAM, and I don't have the energy to lug around a giant brick
For laptops with replaceable batteries there are some aftermarket high capacity batteries you can get.
HP generally uses solid batteries. My spectre gets like 7+ hr to a charge
My laptop has a built-in battery that requires partial disassembly of the laptop to replace. Mine completely gave out, losing power after about 10 seconds after unplugging it. I ordered a new battery and when I took the laptop apart to replace it, I saw that the old battery was bulging. It could have caught fire if I had kept using it.
Dendrites. The problem is dendrites. They’re tiny, nearly microscopic metallic growths on certain materials that occur when the material in question is heated or cooled (for example, during charge/discharge cycles, or by being too close to other hot components in phones/tablets/laptops/etc.). This causes, at least initially, the decrease in battery life and eventual expansion of the battery itself, and can in serious cases cause fires (if the expansion ruptures a cell).
Dendrites also caused the red ring of death on the Xbox 360, and their existence explains why you could fix it by sticking a 360 in the oven - it melted the dendrites that had grown on the solder connecting the BGA-mounted (ball grid array, literally a bunch of tiny balls of solder) CPU to the board. This is a process called “reflowing” and people who are serious about repairing electronics use specialized ovens for such a purpose. Unfortunately there’s no safe way to melt or reduce dendrites in batteries, but there are some promising new anode materials which may help prevent their formation in the first place.
That's unfortunately a side-effect of Li-Ion batteries that's just part of the whole chemistry of the battery. It's literally a case of cramming way too much energy in a way too small space, and the end result is a (comparatively) unstable battery, that will blow out with even the most minor physical damage (that can occur even with just normal discharging/charging if anything goes wrong).
