It seems like that Qnovo thing would disable quick charge under various circumstances like if the phone is in use according to personal test and charging rate records, but that's undesired to me and I would prefer to have the phone ready for outdoor use as soon as possible after i plug my device in, i.e. the original most advertised use case of quick charging. How do I disable that Qnovo technology?
Not possible from my point of view - besides, it is charged quite fast - and if you want it as fast as possible, use flight mode and just let it charge...
The point is I still want to use the phone when it is charging and I'm looking for a charging rate like 50%/30 minutes

Hello,
I have a few questons about my nokia 8 and quick charging.
I haven't had a phone that supports it before, so i'm not sure about how it's meant to behave. I've been reading mixed reports that the charging icon changes or a message pops up on the screen to say its quick charging. I haven't seen this on my phone. Does the nokia 8 have any indication it is quick charging?
I've also read varying people accounts on when it quick charges. Some say that phones will quick charge between 0 - 70%, is that true? I've also read people say that it only works when the screen is off?
I've just ordered a certified quick charge 3.0 charger, so will do testing when it arrives, but I thought the one in the box was meant to be QC 3.0 compatible?
The one that comes in the box is qualcomm qc 3.0 and the one you ordered should support qualcomm qc 3.0 also in order to work.
Indeed the phone quick charges only between 0-80% which is reasonable cause above this the battery should be charged at a lower rate in order to achieve maximum capacity, lower temperatures, better battery health and more charging cycles in it's life, because Lithium batteries "love" to be charged slowly (with low and constant current) and in low temperatures, not above 40°C for sure.
On your device now. Quick charging is heavily depended on software as well as hardware. So when your device is hot for some reason (heavy use etc) it will not quick charge and will charge regularly instead, in order to protect and avoid high temperatures in the battery.
On the other hand when your device is cool and your battery is bellow 80% when you plug and leave it for a few minutes, when you wake your screen, at the bottom of your lock screen it should display "Rapid Charging" at some point. But this can change in just "Charging" if the software detects that your device starts getting hot. In order to achieve constant "Rapid Charging" between 0 and 80% i would advise that you charge your device without a case and on a heat conducting surface (metal etc).
From my measurements and those things on mind my device charges from 0 to 100 in about 1 hour 50 minutes.
Although it should be mentioned that for better battery health you should never leave your battery drain bellow 25-30% and full charging to 100% is not to be preferred due to lithium ion battery behaving nature at very low and very high voltages.
So a great charging habit would be to keep your battery always charged between 30 and 90% and when charging your device be sure that it sits nice and cool and nothing is stoping it from dissipating the heat, that is generated from charging the battery, to the environment.

Options have 50 char limit.. So here are longer descriptions:
- Yes. Fast charging is always ON
- Never. My battery lasts the whole day and I (slowly) charge it overnight. And I am either not in a hurry or good at planning my charging time
- Sometimes. I turn it ON only when I need it
- I don't care or know anything about it. I use default settings
Is there an option to turn it off? I haven't seen it. But anyway i use my old s3 charger for all my devices. I don't trust fast chargers. They kill batteries.
Slow charge really isn't that slow.

Regarding fast changing killing batteries the charger provides a voltage to the phone, the power management controller monitors battery voltage and temperature , I would assume these have limits and will take control if outside of range in a similar way to throttling cpu frequencies when it gets too hot.

Where did you find this setting?
I'm using "bad" cables for show charging but being able to limit the current and the charging state without root, like on Sony smartphones, would be great

The option is in Device Care > Battery > Settings
Personally I leave fast charge turned on and use a bunch of different chargers with the phone, I just have Battery charge limit set to stop charging at either 80% or 90% (depending on when I think I'll be next able to charge) and try to start changing between 20% and 40%.

Using "bad" or cheap cables is really not the best idea, they often don't meet the USB C spec and could damage your device. Try to stick to high quality but low current chargers (Like old phone chargers) or disable Fast charging as previously mentioned.

Strange. My n9600 doesn't have that. I got device maintenance and there's some battery saving options in there but no fast charge option. Oh well the s3 charger works for me.
Edit - nvm found it.

Under the battery menu press the three dots in the upper right corner and select advanced settings. As for the poll I turn mine off.

Thanks finding this option (Samsung UI sux)
Now you're making me ask more questions XD
You have a battery charge limit on an unrooted note 9? How?

It's rooted. I did come up with a solution using the Automate app and a smart plug a little while back but only worked if you're charging from the charger that's plugged into the smart plug.
Yeah okay this 2 ways are well known
Thanks for the fast reply ^^
I was already questioning my eyesight. You know, Samsung UI and not finding an specific setting in menu could happen even after years I think ^^
I charge when I want, as fast as I want. I leave it on the charger overnight, everynight. Have done it this way for years and will continue to do so. Never seen I'll side effects from doing it this way. I have too much of a life to monitor my charging speed and make sure I'm next to the charger to stop it at 80%. I like waking up to 100% and using it as I see fit through the day. YMMV
Fast charging is set to ON by default straight out of the box. So youll think samsung has taken this to consideration.
Personally, i keep this off when charging with the orginal charger. I have an app called Battery Warner which alerts the user when over a set %. or if rooted it will stop charging and enable charging when it is under a %.
If i have plans to go out and the battery is low then ill throw it on fast charge.

My 2 cents:
I think Samsung doesn't care much if battery will remain healthy after 2 years. They care now to sell as much Notes as possible with the "Fast charging" marketing slogan.
That's why it's ON by default.
I never use fast charging as it will provide more harm than benefits to the battery health + I use a magisk module (Advanced Charging Controller) which have cooling mechanism and voltage monitoring and also battery temperature monitoring and this will also greatly increase the battery life on long term use.... since we got a non replaceable battery
Since I rooted my Note 9 on day 1 (I don't care about warranty) the first thing I did is I used Advanced Charging Controller and keeping my battery healthy for as long as maybe 4~6 years of usage

It does, but still the degradation is higher vs no fast charge.
on the topic: The first thing I did on my s7e was to turn off fast charging - the battery after 2.5 years is in a really great shape even after every day charging. The same I did on my note 9. Will use fast charge only if I am in real hurry and need a lot of battery fast. If the phone is changed every 2 year tho, it's not that big of a deal and everyone decides for himself.
Otherwise in most cases it's not needed to charge overnight as 0-100 without fast charging is 2h-2h and 10 minutes. As most charge from ~20%-100% it will take 1:40 to charge the phone. The overnight charge is if the phone is charging from the PC USB - the best way for battery longevity, but not really worth the hassle vs normal charger charging.
According to poll results: more than a half (or 2/3 depending how you will count) uses fast charging.
No, slow on cable and fast charge for wireless!
Photo's by Sully using SM-N960U
The high temperature is an enemy of the li-ion battery. The normal load on the cable drives the temperature to 30.5C. Fast charging on the cable tray at 34.5C. Fast wireless charge up to 37.8C. What better?
Never have and never will use "fast" cable charging. I dont wireless charge either.

Hi everyone,
I have a question about quick charge on this phone.
If I disable fast charge in setting menù and I charge the phone in power off mode, how it's work? It will charge fast o standard speed?
Thank you
connex
i think it will follow the fast charge off setting and charge standard speed
Even I think it will charge in normal speed as you selected in the settings. However, if you use the phone when charging, it will be charging less than if left alone and even if you leave it alone it will be charging less then if you turn it completely off.
Hi
I've searched around to disable sometimes quick charge, because I believe it isn't good for the battery if I use it too often. Normaly I'm charging with syberia intelligent charging up to 80%, in the evening it's fast around 30 or 40 minutes.
Sometimes I want to charge overnight, but it isn't good if the battery charges fast and then pump up again and again to hold the level.
Now I've recognized a file changing will stop the quick charge and with slow charging I believe that it's better to charge to 80 or 90 percent in around 5 or 6 hours.
I've change the file /sys/class/charge_pump/enable to 0 and set chmod to only readable. The phone is charging now slow but it changes back to fast charge after reboot.
The best would be a small app or script to optimize and to choose quick charge on off so that I'm able to change it quickly whenever I want. May there's someone who is able to provide this functionality?
I don't want to take an old charger with 1A to get slow charging... Better a new charger and able to switch the charging procedures....
Is there any way to tell whether the Xperia 1ii is currently fast charging or slow charging?
Sometimes when I plug my USB-C cable into my Samsung devices, it'll says "Fast Charging" or "Charging". If it just says "Charging", i remove the plug and plug it back in and it often says "Fast Charging" (not sure if there's dust or a loose contact between the port and cable", but nevertheless, it indicates that the device is drawing a higher current and is fast charging).
Thanks
I using super fast charger from samsung S20 into sony,but i never seeing " Fast charging" notif in sony
No it doesn't differentiate.
But it uses usb PD to fast charge not quick charger.
So I have Xperia 1 and when I connect a fast charger to it and it shows "charging" that means its fast charging and there is no way to tell? Because my S10 says it right on lockscreen, My oneplus 7 did with doublebolt on battery for dash charging even my xiaomi mi8 did say charging rapidly on lockscreen
Actually, Sony Xperia devices use the Qnovo adaptative charging to charge as fast as possible BUT not too fast in order to preserve the battery health. This is why the charge can be slower than other brands which don't care about the battery lifetime...
You can tell by how much charge % is indicated per minute what mode it's in.
On a 10+ it's double the rate of snail mode in roughly the 30-80% range.
On the 10+ fast charge will not engage if the battery temp is somewhere below 60F (not sure of the exact temp). Other makes are probably similar.
Fast charging does no harm; high cell voltage (80+%) and high temperature are what degrades them.
Low temperature charging can permanently degrade them.
Battery should be above 72F before charging to prevent Li plating in the cell.
Never charge a cell if it's near or below 32F.

Qnovo adapts the charging speed as a function of the battery temperature. It's a patented technology.

Your point? My point is you can readily tell which charging mode it's in by observing the charge indicator/time interval.
Assuming the ambient room temperature isn't extreme.

It's not my point, it's well known that Sony Xperia uses the Qnovo technology. You can google it, it's documented...

And Samsung uses Qualcomm.
Niether lets you to set a charge level limit so both are equally hard on the battery in one of the most important charge parameters.
Does Qnovo chipset revert to slow charging if set to fast charge if temp is too cold?
With Android 11, you can select 80 or 90 % maximum charge. I set it at 80, let's see tomorrow morning

That's pretty cool... if it works.
About time.
I aim for 64-70% most times though. An 80% lockout is certainly better than a 100% plate vaporizing charge.
Charging to 80% worked. Now I'll have to see if I get through 1 day at a single charge

I run it down into the 40's then give it a 20% charge to bring back into the 60's.
Takes 10 minutes. That gives me 2-3 hrs SOT.
I simply charge when taking a break.
Theoretically even though it uses one full charge cycle worth of current throughout the day the actual damage to the cell is equivalent to 20% of a charge cycle.
