Relaxing when you're not so tired it's stressful can help improve your mood, which helps you keep going with doing whatever is positive for you. Get too tired and you lose the motivation to do everything.

So this is just a hint to do things in a healthy manner and not overwork yourself.

I remember seeing a video that claimed that, if it were possible, charging from 50% to 60% was the best. Both extremes (either charging from critical or approaching max) were not looking great on the chart. I'm no electrical engineer though.

The future is now old man. What you said mightve been true for nimh batteries but is terrible advice for anything with a lithium ion battery. Best thing you can do for a lithium ion battery is to not go below 40% or 30%. Second best thing is to not go above 80%

Just got the Accubattery app a year ago for S22+, phone battery started at 95% of spec (apparently it's normal for phones to have up to 10% less capacity than they're specced for, I did NOT know this prior to actually testing) and after 1 year it's still at 95%. The real trick is to charge to 60% max, but you can discharge as low as you want. Disable fast charging, it causes heavy wear. Charging between 80-100% causes heavy wear. Discharging the battery entirely can be bad, however phone batteries are super well protected against this type of damage and often stop battery draw well before the battery actually loses all charge.

Have gone through ~80 cycles in total, or what the battery considers to be 80 full charges/discharges. At about 300 cycles your battery should be at about 75% battery capacity, so instead of being there at 2 years which is pretty typical I should be able to keep the phone in amazing shape battery-wise for 4 years. Every phone I've ever owned got pretty weak after 2 years so learning all this was a huge game-changer.

EDIT: All of the information I used is what I've gathered myself from using the Accubattery app to track my own phones discharge rate and capacity, and this website for the 300-500 cycle figure that manufacturers themselves cite. https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries

EDIT 2: I should've been more clear what I'm arguing for. Charging between 80-40% is worse for your battery than charging between 60-10%, even though you net +10% usable capacity with the second. So if you really want to maximize battery life, go to the lowest maximum charge you're comfortable with (60% is what I use) and go as low as you're comfortable with, most people are comfortable with between 10-20% before charging.

GodOfPlutonium t1_jauglo0 wrote

Do you have some sort of actual source for this? Becuase what " stop battery draw well before the battery actually loses all charge " usually means is that the low voltage protection is set to a high voltage such as 2.7v or 3v instead of the actual minimum voltage of 2.5v. That doesnt protect you nearly as much as it sounds like because the voltage curve is not linear, it flattens out at 3.7v for a while, so 3.3v is already down to 15% left or so

edit: also typical lithium ion lifespan is 500 cycles to 80%

Halowary t1_jaugo0g wrote

This is also incorrect. All modern phone batteries have a PCM (Actually they use a BMS, a more robust sysem than PCM. I use PCM's in other equipment myself so I was biased to this type of battery protection) so they CANNOT be fully discharged no matter how hard you try. You can bring your phone battery to 1% or dead and the phone actually still has plenty of juice left, the PCM just keeps that charge so the phone cant brick the battery. The best practice is to keep your phone battery between 15-60%, you'll get close to 900% charging efficiency vs. charging to 100% (which is 100% efficiency) or charging to 85% (200% efficient) at least according to the battery tracking software accubattery I've been using for the past year.

(Table 2 in my link shows that discharging an NMC battery, the ones used in phones by 100% did in fact cause it to go to 70% capacity by 300 cycles) That 500 cycles to 80% ignores every other kind of battery depleting issue, like the fact that TIME also degrades your battery among several others.. But yeah, all cellphone cells have a PCM that blocks them from going below the minimum voltage by quite a bit.

GodOfPlutonium t1_jaujcz7 wrote

All lithium batteries use protection for undervoltage (aka low voltage protection), either built into cell / pack or built into the device. PCM/BMS is standard, not some special thing that phones have.

You just read that 'technically empty doesn't mean there is no energy left' , because its physically possible to drain a cell down to 0v while protection stops at 2.7v or whatever. Thats not made to add more lifespan than normal, thats to prevent the battery from exploding after you discharge it below 2.5v and then try to charge it. Any cell that has gone under 2.5v should be considered destroyed and not used. It may be possible to revive the cell by charging it up slowly while monitoring heat but is almost never worth it since even if doesn't catch fire it is permanently damaged and will have poor performance. The 'do not do low discharge' advice is for the last part inside the allowed range

Halowary t1_jauk2xq wrote

It's not something that all lithium ion batteries have, and if you used them in something other than phones you'd be painfully aware of how fun it is to install your own PCM which I've done for my motorcycle and several RC cars and Airsoft guns. Replacing batteries often is expensive.

I never said the PCM added lifespan, but what it does do is dispel this myth that it's catastrophically damaging to your phone battery to discharge it to 0%. It's not. Your phone turns off at 10% capacity at the very least (no matter what the indicator on the phone says), otherwise phone fires would be an insanely common occurrence. I don't know a single person who hasn't had their phone die at least once with obviously no issues.

Actually getting a lithium ion battery to 0v is very bad cuz it's dead, but unless you're working with the battery completely stripped of all protections and software it will never reach this point.

My talking about charging ~overcharged~~ overdischarged cells should clue you in that i have experience handling lithium cells. Yes you can buy raw lithium cells that dont have an attached pcm/bms. The point is that it is standard to use them with one. The only use I am aware of that regularly doesnt use one is RC quads where they use a single lvp for the entire pack, necessitating the use of balance chargers and often fireproof bags

> dispel this myth that it's catastrophically damaging to your phone battery to discharge it to 0%.

That myth straight up does not exist. There is literally no common belief discharging your phone to zero will cause to explode. The exact opposite belief, that you need to discharge your phone to 0% regularly to prevent memory effect like you did with NiMH cells, is far more common.

Everyone saying that you should avoid discharging your battery below 40% or 30% is advising to do so in order to prolong battery lifespan. This is something that you explcitly argued against in your original comment, and is what I took exception to:

> , but you can discharge as low as you want.

Yet your own battery university link that you edited in proves that in table 2 and disproves your statment.

> It's not. Your phone turns off at 10% capacity at the very least

I literally said as much before you did

Halowary t1_jauo0k3 wrote

I'm not sure if you're intentionally misreading everything I've posted or not, but I never said that discharging your battery causes it to explode. Table 6, the third best result was discharging from 75%-25%, which was the lowest discharge they bothered to test. The very worst was 100%-25%, and the second worst was 100%-40% and even 85-25% performed much worse. The only results with better performance were 75-45 and 75-65, both of which are basically impossible to maintain if you have a real job where you can't just sit there and stare at your phone battery the whole time.

However they didn't test the range I've been testing for the past year, and the results have been very very good between 60-15%. I Haven't lost any capacity at all as far as I can tell, and it's counting each charge in this range as being about 0.02 cycles but we'll see how this goes during the next few years. At minimum I'm expecting to stay above 75% capacity for 4 years, but if it drags out to 8 I'm not going to be crying about it.

Just so we're clear, in the first post in this chain I did say this: Discharging the battery entirely can be bad, however phone batteries are super well protected against this type of damage and often stop battery draw well before the battery actually loses all charge.

So you're kind of arguing against a strawman anyways. You can pretty safely discharge your battery well below the 40% level and still expect amazing longevity, you're really making the very most gains in your battery by not charging to 100%. The "Don't discharge below this level" gang is talking about miniscule battery life gains, and here I am trying to promote massive multi-year gains.

Once again this belief does not exist. Furthermore

The "Don't discharge below this level" gang is talking about miniscule battery life gains, and here I am trying to promote massive multi-year gains.

Once again your own source doesnt actually prove your point and in part argues against it. Since as you note, table 6 does not test discharge to 0%, it is impossible to actually use it to determine if not charging fully or not discharging fully is better if you had to decide between only doing one. In order to do so would require testing 75-0% in order to compare against 100%-25%

However it does completely and definitively disprove your claim that

> "Don't discharge below this level" gang is talking about miniscule battery life gains

As previously stated the typical 100%-0% lifespan to 80% of original capacity is 500 cycles. Per table 6, the 100%-25% lifespan to 80% was 3500 cycles while the 100-40% lifespan was 5000 cycles. This translates to a 7 times and 10 times extension in battery life respectively.

This is exactly the massive multi year gain that you claimed it did not bring. Furthermore it suggests that the reason that limited maximum charge was not tested in the first place is since it was obviously the first step one would take to extend battery life.

> however phone batteries are super well protected against this type of damage and often stop battery draw well before the battery actually loses all charge.

If you actually go look at a lithium ion discharge graph, as current draw decreases, the voltage curve shifts upward and rightwards. This means that as discharge reduces , the state of charge that a voltage represents is lower and lower. Phones are a low power, high energy application, which means that even if you set the lvp to 3v, a full 0.5v over 2.5v, it represents very little remaining energy. And once again, I did initially ask for a source that showed that phones have some extra protection that normal batteries dont have, which you have not posted.

I'm not going to sit here and argue that the belief itself exists as it's obvious that it does. Lots of people believe a lot of things, to argue otherwise is nonsensical. I've argued against this stuff myself before so I'm not going to take your word for it that it doesn't exist.

What the source I cited does for sure show is that NMC batteries (used in phones) do in fact last for about 300 cycles to 70% if you discharge 100% every time, not your 500 cycles to 80% claim.

Table 6 also shows that the figure I cited as closest to what I'm arguing for (which is 60-10%) 75-25%, had 88% capacity at 5000 cycles as opposed to the 80% for 100-40, with the line definitely trending much more heavily down the Y axis than the 75-25. By 9000 cycles, 75-25% would have 84% capacity while 100-40 would have 69% (nice) 100-25% would have 62% proving that the maximum you allow your battery to charge is truly the main deciding factor here. The depth of discharge for 100-25 is 75, 100-40 is 60, 100-50 is 50 and 75-25 is 50. So comparing apples to apples, the 100-50 has about 74% capacity remaining while the 75-25 range has 84%, a 10% capacity difference over 9000 cycles which is pretty incredible. It proves beyond a doubt that the lower discharge of 25% does not negatively effect the battery nearly as much as how HIGH you charge it does. I'm insanely confident that my 60-10 I use for my own phone is more efficient than the 75-25 they use in table 6, and likely even more efficient than the 75-65 even though I'm able to use 50% of my batteries capacity as opposed to 10%.

As for the extra protection phones have.. https://en.wikipedia.org/wiki/Cutoff_voltage which cites http://www.ibt-power.com/Battery_packs/Li_Ion/Lithium_ion_tech.html as it's source. This shows a cutoff of 3v, although it also says manufacturers set this limit themselves which is kind of obvious. I doubt they set the limit just above what kills the phone, otherwise we'd hear of phones being replaced every few months instead of every 2 years as normal. I also never did claim phones have extra protection, just that they have a BMS that protects them from full discharges. Again with the strawman arguments...

> 500 cycles to 70% if you discharge 100% every time, not your 500 cycles to 80% claim.

I used 500 to 80% instead of 300 to 70% because the better number for standard discharge is better for your position not mine lmao, if you try to recalculate with the worse standard numbers, it just increases the amount that avoiding full discharge saves.

The point being It does not prove anything about discharging to 0%. If you want to tell people not to discharge below 25% instead of below 40% that is one thing, but you have explicitly claimed multiple times that you can discharge as far as you want , which as I have previously explained is demonstrably false using your own data.

There is no strawman argument, you explcitly stated

>super well protected against this type of damage and often stop battery draw well before the battery actually loses all charge.

The term "super well" implies additional protection beyond what is normal. Furthermore you have again linked to a source disproves your own argument. Your entire argument is predicated on the idea that the low voltage protection will shut down the battery with a significant buffer before 0 charge. The graph in your own second link that at a 0.2c discharge rate (which translates to a 5 hour battery life, so in a phone itd be even lower discharge rate), there is 3% energy left at a 3v cutoff. This literally proves what I said in the previous comment

Furthermore,

In this very thread there are plenty of people arguing that memory effect needs to be avoided, and 0 people arguing that it is as you put it " catastrophically damaging", only more wear. Even battery myth articles commonly address the memory effect idea, not whatever youre saying.

Fun fact, Lithium-ion batteries chemically degrade if discharged to very low voltages, and can't retain the same charge as before. The percentage you see on your phone, is just a representation of the voltage that the chemical reaction inside your battery is having.

If your battery is discharged very often past certain "percentage", say for example, you discharge it all they way to 0% every single time, it will lose its ability to retain charge the same way it did.

The body is in a way a battery, an ongoing chemical reaction, just infinitely more complex, but the principle is the same, if you "discharge" your battery to 0% every day, you are definitely not going to make it to 100 years, guaranteed.
