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.
