How much does fast charging cost in terms of battery capacity?

>Have you noticed how phones with fast charging tend to have smaller batteries than phones that charge slowly?
In a swamp of same looking huge phone bricks that ALL have a 5000mAh battery, no I haven’t noticed.
Only thing I noticed is that flagships have sometimes 300mAh less but I thought that was because of design (thinness)

50-65W is the sweet spot imo, quick top-ups when u need it (say you only have 15 mins), otherwise slow 10W (or even 5W) charging overnight, I personally plug into my laptop for that!

I remember the days when phones would go from 0 to 100 in one minute, maybe 2. All you had to do, was carry a credit card size battery with you, you could keep it in you wallet. Pop off the back cover of the phone, put the new battery , pop it back on and that was it. Full charge.
Still feels less hassle as chargers are much larger than spare batteries to carry around....but i guess evolution is not always progress

aReefer, 27 Mar 2022I'll also add that in my opinion, there is no replacem... more
Charging less DOES NOT EQUAL better battery longevity...
Your are seriously oversimplifying fast charging.. charging in general
Have you considered what if the charging speed is NOT from increased Watts but from a different battery arrangement?
We can have the exact capacity 5000mah and exact 18W
BUT a single cell 5000mah will charge slower than two 2500 mah one in parallel.. and let me tell you this you can get more longevity from a dual cell set up .. that efficiency will keep that battery healthier
You also did not consider the damage to battery charging behaviours for those that make it go to 0% or 100%
Same for MMT charge (charging from the center of the battery then "traveling" from middle to top and middle to bottom simultaneously)
You didn't even consider is the fast charging "replenishes" lithium ion
Oppo is able to keep lithium ions from dying
As we see in the article here on gsmarena:

I thought GSM Arena had done a detailed comparison on the decrease in battery capacity over time!

Some people here praise battery longevity. Well, have you seen, in the past five years, a battery that dies in two, three years? I haven't. They last for five years with no problem at all.
Speaking generally, not considering some manufacturing faults etc., which cause some individual batteries to die sooner. But no phone has this problem anymore.
Fast charging? Used it about five times of the phone's lifetime, never much needed.

Pumpino, 27 Mar 2022Are you suggesting that really fast charging requires dual ... moreNot that ultra fast demands dual cell set up..
More so that from a package density point of view.. not necessarily the energy density of the battery itself..it takes up more space in the overall phone to facilitate the technology

I don't care what marketing Hyper Ultra Super Charge Pro+ Max they claim because it doesn't really mean much Samsung's 45W for example is barely faster than their 25W.
For me 0-100% should be in under an hour while generating little heat in all scenarios (summer, under a blanket, while gaming). The phone MUST have a function to limit charge at 80-85% and bypass charging to not unnecessarily Stress the battery.
Battery longevity >> fast charging

IpsDisplay, 27 Mar 2022As usual people are just a bag of irony and they don't... moreAre you suggesting that really fast charging requires dual cells so that each cell is charged at the same speed, and that having dual cells over a single cell battery requires more space?
I was left scratching my head at the end of the article, as unless I missed it, there wasn't a clear explanation for the observed trend.
I really like the 65W charging on my Realme 9 Pro+. However, I use an old 18W Blitzwolf charger to charge my Galaxy A52 5G, which is limited to 25W. Would using the 65W charger with the A52 be a bad idea? I think they use different charging technologies.
Anyway, the 18W charging has never bothered me. I just make sure I allow a bit of extra time.

I'll also add that in my opinion, there is no replacement for displacement.
A phone with a bigger battery will have a longer useful lifetime (years) than one with a smaller battery - regardless of charging speed, simply because battery life is measured in charge/discharge cycles, and bigger batteries need to be charged less frequently (even if the chipset and screen are really efficient in a phone with a smaller battery).
This is especially true with smaller batteries on faster chargers. You'll be lucky to get 2 years out of such a phone without relatively much more significant battery degradation.

As usual people are just a bag of irony and they don't even know it
They claim that 18W ,30, 60W is enough and I just laugh
Because those so called "enough" was yesterday's "too fast"
As I always say slow charging is just ultra fast charging that has become industry standard
You WILL all accept 240W and beyond
Lastly fast charging is just PRICING PSYCHOLOGY 101:
Look up a book called the "Myth of value"
Lol pretty eye opening as to why people chose the "middle options so easily.. smh people are slaves to psychology and don't even know it hahaha

Missed opportunity in this article to talk about how capacity is lost depending on battery structure... Full single cell Vs dual cell.. in which case dual cell takes up more space for parallel charging circuitry
And also battery quality for example 6C Vs 3C etc relationship with energy density/capacity

Charging is still done by humans, sometimes you forget and you got just a few seconds.
Your 10% bigger battery is then useless and you have to think about how to charge it the whole time till you do it. Not too happy scenario.
Wouldn't go back to stone age charge, some brands offer, I would lose my hair.

You guys could have also mentioned the time difference delta in the table. At least the 0-100% would have given a better idea about the trade off.
edit: So sorry, I didn't see the 2nd table, even though I scrolled through the article twice 🤦♂️🤦♂️

I keep a faster charger (original charger) for my Poco F3 in the living room. I think it's around 30w, and it takes about an hour to go from 20% to full, for when I'm awake and may need a relatively fast charge, and a slow charger from an older phone near my bed for overnight charging.
I find that the slower charger tends to do a better job based on how long it takes the phone to drop from 100 - 99% while just using the browser, if that's any indication. After a faster charge it seems to drop much faster to 99%.

I charge my phone (Sony Xperia 5ll) once in 5-7 days so fast charging is not really needed.

As fast as it gets before battery longevity starts to suffer. Also, I'd much rather get a phone with a battery guaranteed to last for a day or two and charge overnight - the charge speed doesn't matter if the battery is able to last long enough to get plugged back in for longer.
