Weekly poll results: fast charging is well loved, moreso when it's standards-compliant

26 July 2020
That's what most people think, however, there's a sizable group that are worried about the negative effects on battery longevity.

I think they have software that senses when you overnight charge and lowers the charging speed by a lot.

It mean, filing it up to a certain level in a given time, so if the guy want to charge it up to 100% during the night, the charge will be managed to charge the phone and make sure it reach 100% as close as possible to when the alarm clock will be triggered, same if the guy want to set the goal for 90% or 80%.
This also include if someone want to keep the sweetspot of 47% to 57%.

And I never said fast charging is bad or shouldn't exist, I said it should be optional, the user should control if he want or not to enable it without having to get multiple chargers for multiple charging speeds, again, the idea of battery management.

The battery is most stressed when it's at 100% and overnight charging leaves it at 100% for most of the night. At least that is what probably killed the batteries in my old iPhones.

Fast charging is great. I charge my battery at 18w and I leave at on the charger when I'm doing something else and it gets to 100% in next to no time.

When will Qualcomm release Quick Charge 5? It's been threeish years since Qualcomm released QC4+ and some nubia phone is the first to use it.

The proper way to charge a device is during long period of inactivity, like during the night/sleep, what the point when the phone isn't even being used for hours to charge it in 30 minutes ?
Fast charging is great for emergencies, when we forget to charge it or we suddenly need to move and the phone is low on juice, but all the fast charging advocates won't make me believe they NEED it EVERYDAYS...

The best would be if a standard could be developed where the phones would ask for different charging speed to the charger, which would be software controlled, so fast charging would be an togglable feature, and if you put an alarm in 7 hours, the phone will simply slow charge in a battery healthy manner, but if you plug it in a hurry and enable the fast charge option, then you get it now that you need it.
With a smart charge time calculation allowing for charging it in X or Y time if you aren't in a hurry like need to go in 5 minutes, but still in 40 minutes you need to get decent battery life remaining.

Battery health management should be the next focus of the smartphone industrie.
Also since battery life in measured in charge cycles, a larger battery is almost automatically the best option, even fast charger advocates can't argue that charging less often (while still being able to fast charge) si better than fast charge by itself.

And with better cooling in general (like the K30 Pro who have incredible hardware for that), the battery should be also able to get advantage of that and enable healthier fast charging, meaning good cooling, for both the SoC and the battery should be mandatory, and **** ultra thin phones, past 10mm there is only diminishing return and no advantage of making them even thinner.

Another thing, would you agree that fast charging shouldn't be measured in Watts nor in time to refill, both because the vast difference between each fast charging tech mean that it doesn't give any clues as to how fast it actually recharge, and because charging a 6000mAh battery in 35 minutes is way better than charging a 4500mAh in 30 minutes.
So we should have a standard where the charging tech receive a rating with multiple letters.
For exemple, based on a 5000mAh battery as a standard for this test, there will be 3 letters giving how fast the battery recharge from 0 to 100%, 0 to 80% and 80 to 100%, as the last percentages are always slower it is important to be able to see how it perform, as if the last percentage are really slow but the rest is extremely fast, it would be quite sad to ,get a low score for 5 little percents.
So the letters from "A" to "J" would be 2 minutes each, from "H" to "V" 5 minutes each, and from "W" to "Z" 10 minutes each, giving a total of 2h to spread the score with good precision on the beginning.
And finally two integer from 0 to 9, the first one being a score of how fast the phone charge with all its tech in real conditions and his real battery capacity, and the second being a degradation score for the fast charging tech it have, in both cases the higher the better.
So, for the exemple lets say the standard is about a 4000mAh battery and the Note 10 have a 4000mAh, a Galaxy Note 9 vs a OnePlus 7 Pro vs Galaxy Note 10 would gave them respectively YUN55, VON55, SNJ55 (I put 55 to all just to simplify).
It is based on this image :

Which, when we learn now to read this score, give a good preview of what the phone is capable of, of course the first digit is also quite important too for charging speed.
At first it look impressive, but I think having this as a standard would help a lot.

Fast charging is good. But I think all phones need to atleast be 27W+ Fast Charging before we move on to even faster charging speeds so we could optimize low battery degradation and battery life. Since 27W is enough IMO.

Forhad1000, 26 Jul 2020I choosed a big battery ^_^I chose*

Fast charge is cool, but phone has to hold for 1 day (full 24h)

I love fast charging
Bought galaxy s7 the same month it was launched in 2016 and still kicking it but now starting to get this messsge that “yr phone battery performance is degrading plz go to a samsung service centre and get it replaced”
But i dont think its cos of fast charging itself and maybe it is because of the reason that i keep it plugged in for whole night even after it is charged ... still it runs very smooth and fast

Plus recently bought 30w fast charger for my ipad air 3 which charges my ipad in 1 hr and 30 to 40 mins ( by in box apple 12w chargers charged my ipad in more than 3 hrs )

So yes.... fast charging is good for me

30W is already a very good charging rate for me. Super-high voltage is bad for your phone. It's not only the temperature that kills the battery, it's also the current that flows and stresses the battery.

Luckily Oppo uses dual batteries in their Find X2 Pro. But had Oppo used a single battery, degradation is worse than 800 charging cycles=91% battery health (other phones can maintain better health).

Don't be misled by numbers. As if huge battery capacity would automatically mean that your usage time is lengthened.

....At the least it is good news to see that so few want to fry their batteries with wireless fast charging. Convenient in usage, but really bad for the battery overall life time if used often/daily

I choosed a big battery ^_^

tbh, 18W fast charging is plenty enough for me anyway.

I am one of them not so keen on fast charging. Use a slow charger to charge the phone overnight and my battery is still decent 2 years down the line. If my next phone has super fast charging I'll only use it for emergencies in case I forgot to charge the device.

For those who change phones often then fast charging is a boon as they don't need to do overnight charging anymore. But for those who are used to overnight charging I don't see much use in these battery killing super fast charging tech.
