lithium ion batteries each have a unique id right...is there anywhere to see it in the os? How does the phone decide what the state of charge is? I am looking at an extended battery that says you should leave it on charge 1 to 2 hours after charge light goes green (95%). Where does the light get the info from? Can the charge profile be altered?
Yes, look on the market.
Once I ran accross one, but I find it useless for myself.

I don't think you can view any battery id on your android and i doubt most batteries have such an interface, most are just labeled backs in a plastic enclosure.
If you swapped for an extended battery i would recommend resetings your battery stats (google for how), or else the charge level may be inaccurate.
The information when to stop charging comes from the voltage.
Some unselfish advertisement, my new app can show you the battery voltage.
No the charge profile can usually not be altered except using a stronger charger to increase speed, but batteries love to be charged slowly... increases lifespan.
So there is no electronic id? I was under the impression that lithium ion batteries used a smart charger and id to track battery data...most computer batteries I have seen each had a unique id so it could track individual battery statistics. Will an extended battery not charge to full when being charged in the phone?

Technical Details
Fits in existing space so no replacement door is needed
Made from the highest quality Japanese cells
Capacity: 1750mAh
To obtain the full capacity of your battery, leave the battery/your phone on the charger for an additional 2-3 hours after the charging indicator turns green or the battery status shows full.
Why is that?
Ya most laptop batteries have such an ID, but i have not seen a phone with one.
I'm not sure why it says to do that.
Did you check out my app?
You set it to you show you the battery voltage, charge till the indicator is green, then note the battery voltage, leave it on charger for 2-3 hours, note the battery voltage again.
If it went higher it really charged more, if not, it was unnecessary.
I don't know if this deserves a message thread but the other one claiming a 100% was closed and it didn't apparently work anyway. But I have found a simple way to get it to 86% when you really want to get it as fully charged as possible. I get mine up to 86% regularly by putting it on the charger while in Safestrap (TWRP). If you had your phone charged to 80% and it won't go higher reboot to Safestrap (TWRP mode). It will show probably now show about 74% in Safestrap.
Let it charge for a little while and it will come up to 80% according to TWRP (Safestrap). But when you reboot to the regular system it will show 86%. Strange but it's a way to get it a little higher. If you put it on your charger it won't do anything until it gets below 80%. I use one of those inline USB volt / amp meter devices between my phone and the charger so I can actually see when it is charging and how much current is being used in the charge. It really does charge in Safestrap to a higher percentage (as seen on reboot) and sometimes the current is well over 1 amp. If for example I stop at 83% though in Safestrap and reboot it will only show 0.0 amp charge in the regular Android system but if I go back to Safestrap it will continue to charge at close to 1 amp.
Maybe this might tell someone who knows more about this to help find a way around that 80% limit.
Note: While this is a quick easy work around to get to 85% or 86% as TheMadScientist has pointed out there is a way to get to 99% or even 100% if you install Xposed framework and a special module as mentioned in this thread here:
Charge past 80% on Snapdragon

I got one of the choetech current cables and it has been totaly awesome. It tells a lot about how these devices charge.
Not familiar with that particular cable but the ones I have can be had for anywhere from $1.29 to about $3 or so on eBay. It is really nice to have and track the current a phone is charging at. And with some Samsungs you can see if it is fast charging or not by the charger voltage output which jumps from 5 volts to about 9 volts when it's fast charging. Also good for detecting bad USB cables.
Using an App like Androsensor the voltage read from the S8 battery appears to be well below a fully charged voltage level. The question I think that needs to be asked is whether the voltage being read is correct or if something in the root process or kernel is causing it to be read incorrectly since charge percentage on Lithium ion batteries closely correlate to the voltage level (unlike some other battery chemistry types). A Nicad or NiMH battery can look fully charged based on voltage in less than a minute from a fully discharged state once it's put on a charger but it can take hours before it is actually fully charged.
As we all know, the charger xiaomi provided in the box does not support fast charging, although it is quite good. For fast charging we have to use different adapters or powerbanks that support it.
Yesterday when I was using my normal charger, it suddenly showed quick charge and two lightning symbols in the top right corner, which indicates fast charging, that I usually get when using my mi powerbank.
First I thought it was a software flaw but sure enough, my phone was charging at a much faster rate and was heating up similar to when I charge using powerbank.
Unfortunately when I removed the charger and reinserted it, the phone charges at it's normal rate, and I've been unsuccessfully trying to repeat it but it's not happening.
My device is completely unmodified, stock unrooted rom and bootloader locked.
I think this means that the normal adapter might be capable of fast charging but xiaomi has disabled it, something worth looking into.
Also I know the phone charges quite fast below 50%, I saw this effect while phone was at 69% and reached 72% in barely 3 minutes or something.
Unfortunately I did not have the presence of mind to take photos as proof.
first of all if you are using charger which comes in box with the phone, its not a fast charger its only 5V2A.
2nd it can't charge at pace compared to fast chargers as it can only provide 2A at max or it may be faulty
3rd it may be software bug just showing quick charge
and in the end you said it charged from 69 to 72 in 3 min. i can say its not fast charging because my charger 5V2A which came in box also charges at same speed you are saying. it normally takes around 1 min for 1% increase but depends on various factors like load being used currently by the phone.
sometimes when data is off or battery saver os on it charges more quickly as consumption is also less so it charges fast.

It was 2% in one minute, I've attached a ss from telegram group of violet where I reported this for proof. My data and wifi were on, and I've enabled always switch on data for faster switching in developer settings.
Even now it's currently happening, but the rate is very slow, I think it's probably a software bug like you say, any idea why this is happening?
Edit 1: That Telegram ss is from the day where I first created this thread, not today.

i know the time is different but why didn't it increased in screenshots you uploaded the time already changed in both of them but battery remains same 69%. its showing fast charging but its not working I guess
plus maybe your battery health is not good.
Hi all,
The last couple of weeks I am having issues charging my phone (HTC U12+), at first I thought it was the charge or the wire, today I got the Mrs phone, which is the same as mine, brought on the same day directly from HTC, running the same firmware, then I got a few different charges, some Quick Charge 2.0 Samsung Genuine, and some Quick Charge 3.0, HTC genuine, and a variaty of good quality wires, and they all work as expected on her phone, Quick Charge 3.0 charged fine up to about 3000mA, I plugged in my phone, at first it shows about 2500mA, that's with the Quick Charge 3.0 chargers, then withing less then a minute I goes down to about 1000mA, and it shows high mV and high temp, please see attached screenshot, the app I have used and always use to test it all is AccuBattery Pro, and by the way do do know that tge battery charges slow for the last 20% or so, but as you can see in the screenshot the battery is bellow that, and when I started the test the battery was at about 25%...
Is the battery on the way out or what?
Thanks

Well, charge speed depends on several parameters.
If your battery is pretty full it's going to slow down charging.
The fastest charge I seem to get is when it's really low on juice.
So I bought POCO X3 Pro earlier this month...So I play games on it mainly and the question is which kind of charging habit is better?
1.Frequently charging to make the percentage between 50%-100%
2.Charge it to 80-90 and try not make to make it fall below 20% and charge only once in a day?
The second option is a bit far fetched for me...Though I will try
My habit is 1 + 2: when around 50%, charge it up to around 90%.
Of course I'm not paranoid about it. But I do check battery levels most times I pick up my phone, to decide what to do.
If you root your device, you can use Battery Charge Limit.
You can set the maximum charging percentage, like setting it to 80%, then the charger will stop charging.
For our POCO X3 PRO, we need to go into this app setting and change "Set Control File" to the one with mi6 or something I don't clearly remember.
ArrowOS has this smart charging built-in.
I personally use my old charger to charge it slowly.
From what I observe, the Xiaomi 33W charger will rise the battery temperature to 40°C, which is bad to the battery. My slow charger will increase to ~33°C.
The fast charge is for convenience and emergency eg. forgot to charge at night and need to rush in the morning.
Frequently charging between 40~80% is better for battery health in long term.
Advanced Charging Controller (acc) is a good module to do this under control. It also has links about battery health explanation. (Battery university)
It is best to keep it between 20-80 present and not gaming while charging. I use my old slow charger when i am not in a hurry.
i keep mine at 70% max. i charge when it gets to 40%. I use arrowOS so i can set max charging and it resets the battery stats as well, so i know which apps eats power next time
Trying to keep it between 40-80%, with 10min break before recharging to cool down
Actually, I always keep my battery between 25% and 75%, then I restart the device once a week. Finally, I will use it until 0% one or two times a month before charging fully to 100% , I have read in a newspaper, it is necessary for digital devices.

discharging at 0% seems to be at a high risk that it won't power on anymore

If you want your phone battery health to last longer for years, like 2 years or more, then it's better. Info is here: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
For long term, battery will degrade and loose it's capacity, so your battery die eventually, then replace, then die, then replace...

If you are wealthy enough to change your phone so frequently that you don't even want to concern the long term damage to phones, then forget about it and go for the TOP. (And coffee for me )

Battery charging: Full versus Partial - 🔋PushEVs
What's better for your electric car battery?
pushevs.com
To be honest, I wouldn't worry too much about any loss of capacity in the battery. My oldest still active device is now 5 years old and even with that I do not notice any significant loss of capacity. Typically all of my devices charge from around 5% to 100%. My Nokia 7 Plus was charged almost daily by me for 2 years and by my brother for a year before that, but I don't know how he charged it. Still, I haven't noticed any change in the running time to this day.
Maybe it's not the place to ask, but I was wondering, is there any way to know if a Xiaomi charger is fake? I want to buy a charger between 10-18w to replace my 33w charger in order to reduce my POCO X3 PRO battery's suffering, but I live in a third world country where is VERY difficult to adquire imported products and I don't want to buy a fake one from the local online marketplaces, if you guys could please help me I would appreciate it

Just buy any 2 Ampere, 5 Volt charger. It should be fast enough, but not too fast. It doesn't have to be a Xiaomi charger.

If you have a laptop, use it's USB. It most likely will charge VERY slow, to the point that you want it to charge faster.
Edit: The alternative way is to use Magisk module Advanced Charging Controller (acc)
You need to unlock bootloader, install Magisk, and install Advanced Charging Controller (acc) module.
Then you can restrict the charging current or voltage. I tried with the official charger and it can be charged below 500 mAh, so below 2.5 watts.

The first two are should be the standard user behaviour, given the ROM build-in recharging warning. The difference in cycles to 70 to 20 % seems huge (6-10x more)

All interesting posts. I wonder however:
What about having the device connected to the charger most of the time (at work place) with 100% most of the time, so it is de-charged only a small time of the day? So only at times when really moving around some workdays or in the weekend the device gets down to 20% or below.
I have now changed the 33W (12V/3A) Fast-Charger with the older 18W (9V/2A) Charger of the RN7 I have.
Would setting the charge limit to 80% give a huge benefit if I would like to use the device at least for 2-3 years?

Connecting to the power all the time at around 100% is bad. It is at the limit of Over charging, the battery may bloat up and destroy the screen.
If you want, it's better to set it limit 40~80% and connect. The importance is the battery temperature. Don't make it hot. You can check it with Ampere.
The benefit is about the battery. You might not need to replace it often when you encounter like cases of sudden drop of percentage or sudden shutdown.
Huge or not is subjective.

Regarding battery temperature at least after reaching 100% I never noticed a hot or even warm phone.
I taught the device/system has some "charging intelligence" when always connected, so that the phone is directly using the power from the cable while the battery is not drained?
In Stock MIUI (debloated) or xiaomi.eu without root it is not possible to set a different Battery Charge Limit then?

When it's about to reach 80% or 90%, smart batteries now will charge slower automatically, so you don't feel the temperature.
However, when you see it in ultra-fast charge, like 40% charing to 70% in 30 minutes, the battery rise to 40°C or higher (as I observed.) Can even go higher depend on climate and using while charging.

This control needs root.
Unless it's built into the Rom.
ArrowOS version 2021-05-07 had Smart charging that can set a limit threshold without root.
But developer said will remove this funtcion. See in his Rom thread for his reply.
