    Do you like the upcoming ultra-fast 200W charging from Xiaomi?

    I don't like it, I don't like it at all, no matter who it is. Meaningfulness ends at 33W. Waiting for half charge 3 minutes (at 200W) or 7 minutes (at 120W) or 15 minutes (at 65W) is not something to live. How many times does a person in a situation of those 12 minutes of mortality need 50% (15 min. Vs. 3 min as the difference between 200W and 65W) in mortality? Well, in such a super-life distress (which occurs once a year in Hungary) I will charge as much as time allows, maybe it will not charge by 50% (eg from 7 to 57%), maybe only by 18% (from 7 to 25 %). It's not enough for that one life-important phone call ??? Even a phone call within 6-8 hours, even for that 25% charge.

    In addition, a fast 33W charge degrades the battery by about 6-7%, 65W probably by 10% and 120W certainly even more. I can't even write about the fact that 200W degrades the efficiency and available battery capacity by 20-25%, so maybe up to 1/4. How do I know? Own experience with Xiaomi Note 10 Pro 6/128 with 5020 mAh flashlight and AccuBattery software. Unfortunately, it measures only currents (A, mA) and the so-called "Capacity", but it is actually a unit of electricity. charge (mAh). It does not measure the charging power (W) or the charging voltage (V), only the battery voltage, which is for two things (we know that the total discharge drops below the nominal 3,6V and the totally charged charge is often above the safe limit of 4,25V). But it shows at least the charging speed, e.g. how much% does it charge in an hour? In a regular USB port (with a capacity of up to 2,4A) and a regular USB cable, it is charged e.g. with normal currents (between about 800 and 2500 mA depending on the state of charge), but especially at standard 5V (no 7V, 9V, 12V or 20V or some super-fine 20 mV steps between what the latest standards allow). So it charges with max. 2,5A * 5V = 12,5W and it drops to 0,8A * 5V = 4W. Yes we see well, it's charging power between 12,5W and 4W. When charging the program like this, the battery capacity really calculates around 5000 mAh. Already when charging between 18W and 12W the program starts to report by calculations after a couple of charging cycles to report only something between 4800-4900 mAh and the supplied 33W charger reduces it to 4600-4700 mAh. Just when it is charged with a power of 33W, it will not get more than 4600-4700 mAh in the battery, even if it is charged from 0% to 100%.

    IN ADDITION, someone can want to charge permanently, let's just give it to 90% capacity and extend the life of the battery more than 2 times (then the Xiaomi Note 10 Pro from 0% to 90% marks 4500 mAh) and not bang it forever at 100% … Wono charge:
    from 0% to 100% theoretically consumes 1 full charge cycle
    from 0% to 99% consumes about 0,93 cycles
    from 0% to 98% consumes about 0,85 cycles
    from 0% to 97% consumes about 0,77 cycles
    from 0% to 96% consumes about 0,70 cycles
    from 0% to 95% consumes about 0,65 cycles
    from 0% to 94% consumes about 0,61 cycles
    …. and e.g.
    from 0% to 90% consumes only about 0,45 cycles
    from 0% to 80% consumes only about 0,23 cycles!
    As can be seen, the dependence of VOBEC is not linear, the closer to 100%, the greater the disaster for the battery.
    Each flashlight wears out with charging / discharging, it has a limited number of charges / cycles, maybe 600, 800, maybe a thousand. Li-ions do not have a memory effect and it is an incredible sin not to use it! Therefore, it is best to charge DAILY, no matter what is needed, e.g. always early in the evening it banged on a medium slow charge below 10-12W for 2-3 hours. Let it be the best, albeit from 35% to 90%. From 0% to 90%, wear is e.g. 0,45 cycles, so from 35% to 90% it will be even less.
    Otherwise, everything below 5000 mAh is not much, just a look or some astonishment. MI MIX4 should have at least 6-7 Ah flashlight. Also the awkward Samsung M51 had 7000 mAh! There are also 10000-11000 mAh smarfons, namely military packaging, a third of a pound, iron three generations behind and a thickness of half a second cm, but the point remains.

    The people started the fast-charging sibat. Nestacilo max. 500 mA (folded as 5x100mA) which gives a classic USB2 port or max. 900 mA (folded as 6x150mA) which gives a USB3 port (at 5V we have 2,5W and 4,5W)

    It had to arrive 1A - 2A or 2,4A at 5V, ie 5W - 10W - 12W charging, and it was also maaaaaaaalo and still not enough, they had to arrive sharply to 3A and voltage not only 5V (5,2V) but also 7V, 9V, 12V and 20V (later with small 20 mV steps in between) which allowed max. 18W-25W-33W or 65W or 100W / 120W dual-parallel charging.

    And as you can see, it's still small, people sibka constantly and therefore I want 200W charging and have the phone charged from 0% to 100% in 8 and 1/4 minutes, while the life and capacity of the battery is degraded by as much as 1/4 even in comparison with the cumulative effect of wear caused by 100% charging.
