    Funny they are stuck at 45 Watt, when other phones have been charging at 120 Watt for years.
    My 2 year old midrange Xiaomi charges at 120 Watt! And the charger was included too! 😋

      Why the hell do you need a 120w charger? My Fold 4 charges in under 45 minutes with a 25w charger and that’s already faster than what I’m comfortable with. The only thing you’re doing by charging faster is reducing your battery’s lifespan.

        If they can charge a car in 5 minutes using 1.3 MW charging, why wouldn’t 120 Watt be fine for charging your phone in 20? Also the charging is protecting the battery by reducing speed as it approaches 100%. The lifespan seems fine, I’m not detecting any deterioration. By today’s standards it’s not even that fast. And it is very convenient to be able to top it off quickly. That way I also don’t have to leave it charging overnight, I can do it while I make coffee and eat my breakfast. That way I minimize trickle charging which can also harm the battery.

        The battery has to be made for fast charging, and Samsung is apparently way behind on that.

        that’s already faster than what I’m comfortable with.

        Then why did you buy a Samsung?

        Do you have evidence to support that claim? Batteries and charging technology have come a long way over the years.

          I don’t care enough to dig up the specific article for you, but if you have the patience to do it yourself, check out Battery University. It’s in there somewhere, along with all sorts of useful info regarding battery technology, all backed by scientific research.

          Bookmark the site and refer to it often. You’ll learn a lot of neat things.

            This site doesn’t appear to definitively support your statement. The secton on ultra-fast charging, which appears to be written in relation to EVs rather than phones, does state that high temperatures and charging over 80%/keeping a battery at 100% can be detrimental to a battery’s lifespan. However, the “scientific research” it claims to reference is nearly a decade old and so there is no mention of the advancements in cooling and charging technology that have occured in that time. It’s the equivalent of someone basing their opinion on the technology that existed when the Galaxy S7 was a new phone. Most (all?) phones come with battery regulation features built into the software now, and there have been many improvements made to internal ventilation and heat distribution as well as the chargers themselves. I’m not convinced it’s as clear cut as you’re making it out to be and this extremely outdated website certainly doesn’t support your argument.
