>just use only 60% of your phone's total battery capacity so that it doesn't degrade as quickly in the future
I've never understood this, doesn't it take a pretty long amount of time for a lithium battery to only hold 60% of its original capacity anyway? I get that you shouldn't leave your phone constantly plugged in at 100% all the time but this shit seems retarded.

It won't degrade to 60% capacity, it will pillow up and force you to get a new phone because shit just isn't made to be repaired nowdays

Just a meme to get you to do more charge cycles and buy a new phone quicker

can confirm. have 7 years old phone charged 20-80 and still holds a charge just fine. says 66% total battery health. not bad all things considered

>>106858362 (OP)
Why create a battery that hates 0-19% charge? Why not create a battery that deals with every % of charge without degrading?

>I don't get how charge cycles for lithium ion cells are counted: the post

>>106858362 (OP)
Phones automatically stop charging at 80% unless they recognize your usage pattern and know you need more charge soon. They also enter energy saving mode at 20%.

just disable gps, mobile data, wifi, bluetooth, sound, vibration, throttle the cpu, and put the screen brightness to minimum. enable or change these only when needed and your battery will last a very long time at baseline

>>106858362 (OP)
You do this when the phone is still relatively new.
As the battery ages you go to 90% and eventually 100% charge.

You can also occasionally charge to 100% when you go on a long trip and actually need that battery life.

>>106859130
i forgot to add: close all apps unless you are regularly using one that requires a lot of juice to initialize

>>106858362 (OP)
If it matters so much then why dont they offset the top and bottom 20% so that the user doesn't have to fuck around?

>>106858794
Why create a battery that degrades at all?
Why not create a battery with 1000 times the energy density that also lasts forever, never catches fire and costs under 1 cent to make?
Yes I am a genius.

>>106858362 (OP)
Meh. My one plus 3t still gets 2-3 days on a single charge and i do straight to 100%

>Battery health assistance
>Lithium-ion batteries are consumable components that eventually require replacement. As your battery ages, Battery health assistance helps manage its long term health and performance. This software adjusts the battery’s maximum voltage in stages. It starts at 200 charge cycles and continues gradually until 1000 charge cycles. This helps stabilize battery performance and aging.
>As your battery ages, you may notice small decreases in your battery’s runtime. Based on adjusted capacity, Battery health assistance also tunes the phone’s charging speed. You may notice a slight change in battery charging performance.

>>106859162
Tesla did that on some of their EV models, even offering a software unlock to use the remaining capacity.
People hated it.

I've been doing 80/20 for years since my EE father told me about it, and had been applying it at his work space since the 80/90s.

Even with only 60% charge my phone (1 VI) is good for two days, and if I need more it has a one-tap that says charge to full once. Popping open modern phones to replace a battery is a pain in the ass, so attempting to avoid that for as long as possible makes sense.

>>106859201
>It starts at 200 charge cycles and continues gradually until 1000 charge cycles.
That seems backwards but understandable from a sales and planned obsolescence point of view.

They let you use full capacity when the phone is still new but by the time the new model hits the market you get smaller and smaller charges encouraging you to buy a new phone.

I do the exact opposite: protect the battery when my phone is still new but squeeze every bit of life out of it towards the end.
But then I want my battery to last unlike Google.

>>106859212
>one-tap that says charge to full once.
I wish my Samsung had that feature.
I have to manually change the "battery protection" setting from "maximum" to "basic" and then remember to set it back to "maximum" again after charging to 100%.

>>106859330

Yeah it's quite nice. I'm honestly not sure what people who make the interfaces are thinking. They've all these examples of what is a good/bad idea, and yet they just choose to ignore features that would become the norm, especially a big company like Samsung.

>>106858362 (OP)
Never had a problem going from 0-100. My phone is over a decade old.

idk if this is different for newer si/c batteries

>>106858444
I've had the battery in my current phone replaced, it's a service first or third parties will still do.

>>106858362 (OP)
In my experience, it all seems to be luck.
If there's more manufacturing defects in your battery it will degrade faster. I had phones that did 1200 cycles at 87% health, and some laptops that are at 83% with 250 cycles.
Lifes too short to micromanage battery percentages, so I just use what I use per day and charge them overnight with a slow charger if it gets too low.

>>106858362 (OP)
>>106858371
It would take about 8-10 years for a current phone battery to degrade 10-15% from peak capacity.
By then you typically have replaced the phone for other reasons...

you follow the rule on a brand new battery and when you don't really need the power. if im near an outlet at 20% on my brand new phone i'll get off my add and charge it. you're overcomplicating it

>>106860522
lolno more like 8-10 months faggot

>>106860522
your battery will turn into a jiffy pop grenade within 3 years.

welcome to reality, now exiting theoretical fantasy land

>>106858362 (OP)
Okay so i do this. And I know a lot about batteries. I also have my phone on my desk most of the days on a charger.

The very short version is that it makes it much less likely for the battery need to be replaced which is a pain in the ass. I want to use my phone for at least 4-5 years depending on the updates. I don't want to need to replace the glued in battery.

>>106860486
apple does battery replacements for super cheap lol

>>106858783
6 year old phone. always let it die and cahrge to 100% leaving it pluged it over night every day. its a non issue my battery is still good

>>106858362 (OP)
People call me the battery whisperer. Still have an iPhone 4S on the original battery. Too be fair it sits in a Faraday bag for most of the day.
Meanwhile people I know are already getting their iPhone 15's battery replaced.

>>106860714
Same here, OnePlus 3T. Never do this 80% duck shit.

>>106858362 (OP)
>doesn't it take a pretty long amount of time for a lithium battery to only hold 60% of its original capacity anyway?
I mean I just had to replace my phone's battery after less than three years. But idk I guess that's probably an eternity nowadays.
Ultimately I think a battery and the phone are meant to be equally disposable. It's probably not worth stressing about micromanaging your charge levels.

>cap 40% of the capacity because yes.

Fun thing is that I never heard about that before 2024.

>>106858362 (OP)
Same rule as peeing in a toilet. Careful when you first aim, and careful when you are finishing.

>>106858362 (OP)
this shit is so fucking stupid. if the battery has a capacity of x amount, charging it to 80% of that amount leaves it at 80% of the capacity given, all the time. this doesn't degrade the battery less, it just charges it to 80% of it's rated capacity. Why wouldn't you take advantage of the rated capacity while you actually can? the battery is still going to degrade through charge cycles regardless, and the entire time you're not taking advantage of it you're effectively cucking yourself from extra run time.

>>106858362 (OP)
We need a class action lawsuit. There's something wrong with selling you a battery is advertised on using 100%, but then the phone harasses you into only using 60%.

I use the 40/80 rule?

>>106858362 (OP)
Batteries are >$100 to replace (that's counting labor too, it's even cheaper if you're remotely competent), it's just inconveniencing yourself to save pocket change every few years

>>106858362 (OP)
its some cope shit, your 100% is already 60% of the real capacity.

>>106859103
no. that is what they *should* do. they don't do that.

>>106859130
yes, just don't use your phone

>>106858362 (OP)
Why dont they make it so the phone stops charging once it reaches 80%? Am I supposed to babysit it every time I chatte it?

>>106858362 (OP)
what about 90:10?

>>106861976
pretty sure there are settings that let you enable this on some phones

>>106861976
Most modern phones will have this as an available setting.

>only use 60% of your battery capacity
>why?
>to prevent your battery degrading to only 60% of the original capacity

>>106858362 (OP)
I hardcap my Steam Deck to 50% because I'm not far from a charger when I'm gaming. I keep my iPhone at 100%.

>>106861976
Mine does that at 85%

They need to make LFP batteries for electronics. The better longevity is worth the lower charge capacity. I'm sick of looking through sketchy sellers on ebay for replacement batteries.

>>106858783
>40%
Because you don't use the rest.

>>106858362 (OP)
I have literally never done this and I'm am using a 9 year old Galaxy S7 that lasts as long as I need it.

>>106858783
It says you have 66% battery health because all the cells in the top 20% and bottom 20% are never used.

>>106858362 (OP)
I charge to 100% and basically never let the battery go below 30% and I've never had battery issues with my phones

for me, it's 0:100

>>106861976
You can make iphones/ipads stop charging at 80%. Probably same with android phones too

>>106862729
This plus not using the phone while charging or when it's hot. That shit will degrade your battery for sure

charging from 40 to 60 is even better

>>106858362 (OP)
People who only charge up to 70%-90% are retarded. At that point you're just spending more money on a larger battery just to not use it at all. By the time the battery starts noticeably degrading you'd already have a new phone anyway. You might even be on your 3rd phone.

I let it go from 100 to 5 and use the quick charger that came with it
but only charge every 3-4 days and turn it off for the duration
when I'm not using it, it's in airplane mode
5 years and still working well.

>>106860988
just because you're ignorant of an issue doesn't mean it's a new or made up issue. even my laptop from 2008 has this as a built-in feature
