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.
To charge your phone faster? What kind of question is this?
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?
I’m curious what car charges at 1.3MW. Most I’ve heard of is closer to a quarter of that, and that’s only for 20-80% before it drops back significantly because it generates significantly more heat gain the upper 20-30%
I’m curious what car charges at 1.3MW
BYD has the entire 1MW system ready in cars you can buy today, with charging stations for it being rolled out in China.
CATL has a battery capable of 1.3MW, but it is AFAIK not available in any cars yet.
Current high end Chinese cars on the market in EU are about 400 kW charging.BYD Charges at 1MW, although they will probably not be available in America due to protectionism.
1.3 MW is the newest CATL Battery, which for American manufacturers were supposed to work with, but may be impossible now too due to protectionist tariffs.https://insideevs.com/news/756144/byd-han-l-megawatt-charging/
BYD is launching two EVs that boast “Megawatt” charging capability, capable adding about 250 miles of range in just 5 minutes.

peak charging rate approaching 12C with maximum charging power exceeding 1.3 megawatts
But even a pretty average 80-85kWh car today can charge 10-80% in about 20 minutes. More expensive cars do it in 15 minutes.
Trickle charging does not harm batteries. On the contrary, the slower you charge a battery the safer it is. This is why all battery protection reduces charging wattage as the battery gets more and more full. Fast charging damages batteries, faster charging means faster degradation. There’s no way around that, it’s just physics, entropy comes for us all. Battery makers are just betting you’ll buy a new device before it becomes noticeable.
Trickle charging does not harm batteries. On the contrary, the slower you charge a battery the safer it is.
Charging when the battery full or very close to it is absolutely harmful, and that’s what trickle charging does. It especially harmful if the charger isn’t 100% accurate, and especially for Lithium batteries.
Apparently some people also use the term for just slow charging in general, but this is obviously what I meant in this context.
Trickle charging compensates for self discharge and the idle power used, so even when accurate, to keep charging a little bit to maintain a 99%-100% charge is definitely harmful.
It’s way better to only charge to 80% for instance. Which is the reason all fast charging times for cars a measured up to 80%.Trickle charging is damaging if for instance you charge your phone when you go to bed and don’t disconnect the charger until morning, that means many hours of trickle charging at near full capacity.
Because my phone charges fast, it never trickle charges for long at near 100%.
Phones have had pretty good battery management for many years now. My phone adaptive charge gets to 80% and stays there without charging until 20 minutes before my alarm when it activates charging again to get to 100% exactly as the alarm goes off. The default behavior is a basic care that makes it so the battery stops charging at 100%, waits to drop to 95% then goes back again to full in a cycle. The risk of overcharging from leaving a phone charger connected overnight has been null for about a decade. Fast charging, on the other hand will always degrade the battery. It is way too much tension over way too short of a time span.
Trickle charging has only ever meant keeping electrical voltage on a full battery for acid batteries (actually overcharging). It has never meant that for consumer electronics.
It is way too much tension over way too short of a time span.
Except charging speed of a phone depends on the capability of the battery used for that phone, and new batteries that are made for it, can handle way faster charging than older batteries.

Oh my god, that is the absolute worst. So the day you are extra busy and have to get up a little earlier than usual, and depend more on your phone than normal, it’s only charged to 80%! That’s exactly the kind of unintelligent solutions I hate. They always fuck up when it’s most inconvenient.
the battery stops charging at 100%, waits to drop to 95% then goes back again to full in a cycle.
So repeated charging from 95% to 100% which is clearly not good for the battery.
You are wrong in all of your replies, but I have ran out of time to educate you. Good day.
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.
The way those super-fast charging batteries work is usually by splitting the battery internally. It’s not one battery charging at 120W, it’s 2 charging at 60 (or 3 at 40).
I can’t wait until one if these devices blows with 5000mAh of energy
Or…just make a damn removable battery And allow people to buy new batteries. I don’t need my phone to charge in half a second with a high chance of it exploding or killing itself from being charged at high speeds…I just want to be able to replace the shit you glued in
You can still replace the battery. It requires more work but it’s generally not a complicated or difficult process on most phones and you only have to do it every few years. I’m not trying to defend non-removable batteries, but I think sometimes consumers pretend they are more powerless than they actually are over these issues.
With a replaceable battery, you just carry a second one and swap them on the go
You shouldn’t need to do that anymore, batteries are much larger and chipsets are more efficient than when removable batteries were the norm. But even if you do need to charge, that’s why fast charging exists.
In which you’d need a power bank and cable that youre carrying if you don’t want to be tethered to an outlet (which may or may not be available.)
Seems a second battery is just a better option.
How do you charge the 2nd battery? Do you charge it slowly when home and keep it as spare while you use your main battery and wait for it to charge to full.
Remember when you too some spare AA batteries with you for your Gameboy/Walkman/Discman so that you didn’t run out of juice in the back seat of your parents suburban on the way to grandma’s?
Pepperidge farm remembers.
There used to be external chargers. I’m not speaking Nokia times, I had a Xiaomi phablet with Android 5 or 6 with one of these. Just a frame for the battery with an USB input.
I have a Fairphone with swappable battery, I keep one charged at 80% in case I need a quick reload of my phone. And after I used it, I recharge it in the phone and swap back to the empty one to also recharge it.
Carrying a spare battery is much more compact than a power bank and charging cable though. Or even a wall adapter and charging cable, which also requires an outlet.
Just a sec Mom, I’ll just change my battery!
honestly agreed, I don’t mind the fast charging, but I would love removable batteries. Even if it meant shorter life spans. like I used to be able to pay 20-30$ on a battery and replace it, but now you need adhesive and a heat gun
I read somewhere about a phone that had 2 batteries, that way you could swap batteries with the phone remained turned on during the process!
my headset does this, I’m spoiled by it and I’ll never go back. I’m fully ok with putting up with some of the issues with the headset exclusively cause of this feature. It’s so nice
Can you share the model name of your headset?
I’ve used two headsets that done it, the Arctis Pro Wireless and turtle beach stealth pro, I highly recommend the Arctis Pro wireless over the turtle beach though as the Arctis Pro wireless was a seemless swap, where the turtle beach has a 10-15 second delay swapping battery.
Used to be somewhat common as I recall back with flip phones (yes Im old.)
New shiftphone at least has a replaceable battery iirc.
I’m pretty sure taking out the battery of a feature phone would turn it off instantly.
Nokia n900 could do it live, with a charger connected instead of a second battery.
You disabled the watchdog, because root access was officially supported, turned the brightness way down, connected the charger, and finally swapped the batteries.
The old ThinkPad T480 has this: an internal battery plus a hotswappable external one
Yeah my T460s has an internal and external
That was the case on the old Motorola StarTac. One battery was attached to the top of the flip, and then there was a larger battery that could be clipped onto the back. Both would power the phone so as long as one had power you could swap the other.
My Xiaomy (2, 5 note pro) had that, just power off, pop the back, switch in a fully loaded 5€ 3200mAh battery and go.
Had a “station” for charging them too.
I mean after their latest hideous UI 7 update I’m never getting a Samsung again. I’m tired of them chasing Apple trash.
Imo It’s not quickly charging that’s an issue, more about the capacity
