in short,, BBK Dual Cell charging technology actually good thing??
BBK 60watts charger is dual cell battery each charge for 30watts.
so battery capacity won't drop ,,
Unlike single cell battery charging

Anonymous, 27 Mar 2022You need to admit chinese brands push this because they wan... moreFake news, xiaomi guarantee for at least 800 charging cycle lol
And if you buy a fast charging capable phone, and you want to use your old charger to maintain battery life as long as possible just go ahead
My question is, I can use slow charger when my phone have 120w capable phone, and can I use more than 30w charger when I need to top up faster for example the latest iphone?

IpsDisplay, 27 Mar 2022I don't understand what your saying can you explain pleaseYou need to admit chinese brands push this because they want to make money by replacing batteries or selling more phones when batteries get damaged.
They do not care if battery loses 10-15% after few months.
Even xiaomi admits it can lose 10% per year, which would be at least 450mAh.
Explain to people why no phone with more than 65W remains below 42 celsius while charging? That is surface temperature, not inside the phone, where is hotter.

Most of all, I want a choice. When I plug in a wall charger I want the phone to start charging as fast as possible (like it is now) but I wanna be able to roll down the notification bar and manually switch to show charging. Because, why not? If I know I'm done for the day I can preserve my battery's healthspan.

dbjungle, 27 Mar 2022Source? Apple offers a 140W charger for the M1 Max Macbook... moreIt has multiple cells, which makes it a bit above 20W per cell. It's not 140W per battery cell........

This article gives a very misleading idea about how much battery capacity fast charging costs you in terms of battery capacity. There is no no magical battery on the market that can sustain very high charging speeds without impacting battery life and the impact is very measurable, you can either have a battery that charges fast or you can have one that lasts a long time and then you can have some stuff in between.
Batteries primarily degrade in 2 ways: battery lifetime (aka age) and cycle lifetime (aka total charge input/output) when charged and discharged under ideal lab conditions. On top of that, if you fast charge a battery of keep it at very high charge levels for a long period of time or completely drain it every charge cycle, its cycle lifetime will decrease much faster than if you charge it slowly and keep its stored capacity around 50%.
Ideally, you don't want to drain your device under 15% or over 85% and you don't want to charge it faster than 0.5C speed (about 2h for a charge in practice). 1C charging speed is dependent on battery capacity, it's equivalent to charging the full battery capacity in 1h. Charging a 5000mAh battery at 1C means charging it at 5A or about 21W.
Going to 1C charging generally loses you only a little battery life, there are some batteries that are specifically designed to take up to 2C charge without too much loss of life (at the cost of lower capacity) but once you go over that, things go fast indeed, fast charge and fast losing battery capacity over time. There is a reason car manufacturers recommend against fast charging electric cars all the time and that's while those cars all have spare capacity build in, there is no spare capacity in mobile phones, so the impact on battery life will be much more pronounced. Of course, you might not expect your phone battery to last 10 years while still having 80% capacity, but it would be nice if it lasted 5 years at 80% capacity. Fast charging all the time rules this out, you will be wearing out your battery long before then.
100W charging on a 4000mAh battery is roughly equivalent to 6C charging... 3 to 6 times higher than recommended and 12 times higher than ideal. Since there is no way to set charging speed on phones (ie. there is no setting in mobile OS to tell a 100W charger to charge at only 15W), if you have a phone that will fast charge and use a fast charger, your phone is going to fast charge. So you will have to explicitly buy a slower charger to get slower charging done. There is no reason why this cannot be done in software btw, the phone tells the charger how fast it wants to charge, that's how modern charging works. It would be dead easy for phone manufacturers to integrate such a setting or a setting to disable charging over a certain %, but they don't want that, they want to get you hooked on conveniency and buying a new phone every 2 years because the battery life has gone to hell and replacing the battery is so inconvenient most people skip it and just buy a new phone instead.
With software support now going to 4 years as expected standard on modern medium range phones, battery longevity will be the determining factor for how long your phone lasts, not whether you still receive updates from the manufacturer or not. And battery longevity is partially in the hands of the consumer, don't fast charge, it's a pointless feature for 90% of the time and for the remaining 10%, you can get around that with some planning and managing. Alternatively you can participate in the modern day consumer waste society and use some more landfills...

Olympus Oms, 27 Mar 2022Of course the smarter pays more than the rest, right. Gj m8. Smarter can afford to pay more. Would you rather be poor and try save 50 bucks here and there, or have more money, normal life, be able to waste money according to you, pay more, just because you can. Life will pass us by either way, I know which way would I rather live it..

Gsmarena team, how about measuring temperature during the charging as well?
Would be nice xiaominions trying to find excuses for why the xiaomi phones with 120W get so hot, near 60 celsius.

I have noticed. None of them with 80 or 120W has more than 5000.
While ones below 67W have more than 5000.

Ah poor people and their even poorer logic. Just because you're poor, you don't have to think poor too.
Ultra fast charging.. Put a phone on charge.. Take a crap.. By the time you wipe and wash your hands, the phone is fully charged.. Off you go for the whole day..
Once you go ultra fast charging, you never go back. Only people that have never had that, can come up with a crap to justify slow charging, despite justifications being totally baseless.

DrakeX, 27 Mar 2022This article feels weird. I thought the writer made a study... moreYou have a theory you say :)) Try research instead of having theories. Battery cell is fitted into a housing battery case. A single cell battery can fill up the entire case. Ultra fast charging technology utilises dual cells, as in two smaller cells instead of one big one, so they both charge simultaneously and achieve quicker charge.
So, in a nutshell, those two cells are interconnect via a circuit that ensure parallel charging. That circuit takes up on average about 10% of the battery housing case.
To summarise, same case with a single cell battery usually has about 10 % more capacity than a case with dual cells in it.. Ex.. One can fit 5000mah battery, the other 10% less, about 4500.
Case in point, latest neo 3 gt phone, same phone, same battery housing case obviously, since you can't fit a bigger one in the same phone, one with a single cell battery has 5000 capacity, the other with 150w dual cell, has 10% less.

My POV on fast charging is, anything beyond 25 is unnecessary if it is effecting your battery capacity over the course of time.
People talk like i can change mine in 15 while yours take 90 minutes
So what ? I don’t need to charge my phone until i hit the bed, and i always have 40-60% by then, the charger i use is 10W wireless charger. Its more than enough.
When i am up the next morning my phone is 100%
And i have noticed, before i was using a fast changer my battery degraded faster, but its been 7 months its been very consistent
Coincidence ? No
Don’t make these phone companies brainwash you into some stupid marketing scheme and stop doing their bidding.
Its been proven that fast charging does effect battery capacity.
You could be the person who needs it but for an average user, its not a feature just a gimmick.

Not sure why manufacturers think people care too much about the speed of charging. Everything around 30w is pretty ok. All we need is long lasting battery 🔋. But they even put smaller battery on power efficient chips to not put too much attention on the particular model(11 lite 5g). Another feature that there is no reason to exist is curve screens(this only increase the price and make it more "premium"). Manufacturers tend to not think about customers anymore, just the profit. And this year will show this. We will have the same phones with new names.
