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

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
My Xiaomy (2, 5 note pro) had that, just power off, pop the back, switch in a fully loaded 5β¬ 3200mAh battery and go.
Had a "station" for charging them too.
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!
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.
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.
The old ThinkPad T480 has this: an internal battery plus a hotswappable external one
Yeah my T460s has an internal and external
Imo It's not quickly charging that's an issue, more about the capacity
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! π
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.
thatβs already faster than what Iβm 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%
Iβm 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.
https://www.perplexity.ai/discover/top/catl-unveils-battery-charging-K2CWUCOTQuuj6G_DkbaTjw
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.
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.
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).
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.
