Xiaomi 12T Pro can be charged 100% in just 19 minutes

That can't be good for the battery

 

Same thing was said for 15W charging back in the day, please get over it already.
And 120W charging isn't something really now, it's been out on the market since at last a year, personally I know the Redmagic phones, but I'm sure oppo/vivo had it too before along side other companies lol

 

Fast charging is unavoidably detrimental to battery life. It's as much a fact back then as it is now.
It's the reason many phones have a slow charging option for overnight charging.

15w is hardly concerning. It's slightly more than double the recommended charging wattage of a phones Li ion battery for maximum lifespan. 120w is over 15 times that value.

At this point it's a marketing gimmick. Nobody really cares about fast charging at that degree. Almost everyone wants better capacity and life from their batteries.

 

Yes it is rather punishing to the battery , but not as bad as you think . The battery in a nutshell is split in smaller compartments . So is not 1 big battery receiving 120 watts but more like 8 small batteries receiving 15 watts each ! ( I did not search to see in how many compartments this specific battery is split though)

Some times I trickle charge my phone on 500 mah .... It lasts me for days on one charge and when I sleep I do not care for fast charge. But it came really handy few times .

 

It might not seem this way but battery technology was a lot worse back when 15W chargers were first being introduced. It's pretty well established that charging batteries too quickly will shorten their lifespan. Of course, "too quickly" depends on a lot of factors; 15W is far from too much for just about any modern phone.

What does being new or not have anything to do with it? Doesn't change the fact that it is very likely shortening the lifespan of the battery. Phone manufacturers are always looking for excuses for consumers to replace their phones. What better way to do that than to have conveniently short charge times and a battery that lost most of its usable capacity in a much shorter time frame?

The stupid thing is, what's the point? The only time having such a short charge would make sense is when you're driving or in a public space, where you aren't sure if you'll have enough to get you through whatever it is you're doing. Well, most cars with built-in USB ports don't go much higher than 15W. Best-case scenario, you might get 80W from a fancy cigarette lighter adapter, but even then, most are probably only going to support a peak of 40W. As for public chargers, most of them are total garbage and can barely provide 10W, let alone 120W.
So, the only time you can really take advantage of the full fast charge potential is when you're at home, where typically there's no rush to charge in 19 minutes. I would much rather trickle charge and extend my battery's lifespan.

 

@schmidtbag I see it differently , is a nice to have feature and you use it when you need it . My Poco x3 pro has 65 watts charging 99 % of the time I do not use it . But the last roughly 1 year I use it happen 3 or 4 times to forget to plug my phone in plugging it on the fast charger for 15 mins was more than enough to give my phone enough juice to last till the night . No doubt it shortens the lifespan , people that use only fast charge either do not know any better or they update their phone every year and they do not care .... Or a bit of both.

 

120w charging has been out for a while now (last year). According to Xiaomi it does impact battery life but not as bad as one would think. 800 charges loses about 20% bat capacity or roughly 2 years usage, which is about the time ppl upgrade their phones. So with 5000mAh, you are down to 4000 in 2 years which is about what many new phones come with. If worried, you dont have to use it, just use a 15-30w charger. But nice to know if you need ultra quick charging in an emergency, the option is there.

Btw, they also announced a 200w charge capability which can recharge device in 8 min.

 

I completely agree that it's better to have the option if you need it. If your charger allows the rate to slow down to preserve lifespan then great.

 

pretty soon we'll be charging them via the 12VHPWR

 

They could easily have a charger with 2 USB ports but they do not , you have to use a slower charger thankfully I have tons of those XD

 

Less of a fire hazard than what's happening with USB-C.

I wish I was being sarcastic.
