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.

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.

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.

Is it normal behavior that supercharge "slows down" as it gets closer to full charge?
I am asking because i have noticed that my 1 month old P20 Pro charges slower even though it displays "supercharging" on the display? Maybe i am imagining things, because the battery was at 89% when i plugged it in.
I have used Ampere to monitor the charging current ant it stayed around 750mA during most of the charge and dropped to 450mA at the end.

As far as I know, the low battery power of mobile phones is usually due to the fast charging speed. When the charging rate reaches more than 80%, the battery power is close to the full. In order to ensure the safety of use and extend the battery life, when the battery is rapidly charged, the charging current output by the charger will gradually decrease and the charging speed will slow down until it is fully charged. This feeling is normal for you. How long does it take you to charge from 0% to 100%?
Yes - This is generally a safety measure for the battery.
How long does it take from 0% to 50% and as far as I am aware it slows down from 60%
Thanks for your replies bobo and mulkman.
It is reassuring that my device is ok and (hopefully) I am only imagining things
I haven't had the chance to charge from <50% to 100% but I will leave the phone to go below 50% over the next few days and charge it up to 100% and post the result.
Finally my phone discharged enough so i could do some charging.
Started at 44%
Total charge time 66 minutes to 100%.
Supercharge indicated 100% of time.
Meassured approx. every 10 mins (6 time points)

Everything was on, but the phone was on WiFi. Temperature of the battery did increase to 32 degrees centigrade (checked in Ampere). The phone is in a original Huawei smart case, which may increase the temperature.
It's probably about right. It slows down at the top. Attaching a couple of charging sessions for comparison. You can see that the percentage per minute decreases when the battery reaches the higher levels of charge. At the rate of the first picture/occasion it would charge the battery in half an hour. But that's not the case since it slows down a lot.

Good to hear.
Is your phone in one of those TPU case and if so remove it before charging your device.
The charging speed is dependent on the current battery temp so it may throttle if your device gets too hot

Yes most definitely.
Have you ever noticed that the phone gets warm during the first 0-70% of its charging cycle.
Towards the end the phone enters trickle charge mode to protect the battery

I haven't noticed before. I usually have my phone on the table while charging and i dont pick it up. But when monitoring with Ampere I noticed that the temperature went up.
Ive purchased a Galaxy S20FE (Exynos) version 4days ago. I also purchased a 25W Samsung fast charger. I am getting slow charging speeds. When mobile was on and idle it took 2hrs 10 min to fully charge. (My mobile data and GPS was off). When mobile was off it took 1hr10min to go from 20 percent to 100 percent. Can anyone tell what's the problem?
I am from Delhi. I use two sim cards. I have not rooted or installed any big games.

It's dropping out of fast charging.
Excessive low or high battery temperature.
Between 40-65% it should charge at about 2% @minute if temp is above 60F and below 100F.
At about 80% it should drop out of fast charging to protect the battery.
You need an approved fast charger brick (minimum 25w) and cable. Make sure cable plug is fully inserted into the brick.
A failing battery will cause erratic fast charging; replace battery if any signs of case swelling are present! Check for this... been there, done that

It wouldn't have fast charged at all if not enabled; 3500ma draw indicates it is enabled.
You can try toggling that toogle 3 times on/off while not charging. Sometimes this helps.
Try a known good (new) Samsung 25 w brick and cable.
Clear system cache.
Try a hard reboot (simulates pulling battery)
Make sure the C port contacts are clean.
A factory reset will most likely do nothing except waste your time.
If none of the above suggestions work it's a strong possibility you have a bad C port charging pcb or... a failing battery.
Any case swelling means replace the battery asap☠
A nominal fast charge profile; Note 10+ with a new battery on a Samsung 25 watt brick.
Starting battery temp was 70°F
Start 48% 4895 ma
65% 4100 ma
70% 3700 ma
The current draw can fluctuate as the charge increases depending on various parameters like temperature. Generally the draw is stronger at deeper discharge levels then tapers off as it approaches a 80% charge state. At 90% or so it will be around 800ma. At 100% the draw is 0ma.
I was thinking the phone and charger have to communicate for the charger to know the phones preference of current draw, the 3700mA dropping down could indicate that setting being received and adjusted to.

With a 3700 ma draw fast charging is engaged.
Erratic fast charging is a strong indicator of a battery failure especially if it's capacity has noticeably decreased.
I watched this type of behavior for about 2 months. It started suddenly.
I was fortunate the swelling battery didn't damage my display or worse. It sits right against the display and it's thousands of mosfets and OLEDs. That matrix is delicate...

If you're using the Samsung fast charging brick/cable return the phone now if you still can.
No reason to deal with a factory defect with a new phone. Better safe than pi$$ed
That reported battery capacity is within normal parameters for a new battery.
No app can tell if the battery is failing other than poor capacity. Any rear panel or display bulging is a dead giveaway sign of battery failure.
Note, what Android reports as battery capacity can't be trusted It's dumb as rain.

it could be either the phone or the charger that has a problem, it's possible that it is more the 25watt charger if the 15 watt charger works as intended. I'd get both looked at, you want to be sure after the money you've spent.
I have baught this 25W Charger for my s20 fe. But, whenever I try to charge with this after several minutes of charging charger gets disconnected and reconnects within seconds itself and it continues. There is no such issue with original 15W charger. My phone is rooted & custom recovery installed.
Is it software issue or hardware issue? Any idea?

Not sure about that device but always start by using the OEM fast charger and cable.
Replace OEM charger/cable with same if not fast charging only -then- look for other causes.
A defective battery will also cause erratic fast charging. Any signs of case bulging indicates a battery failure and needs to be addressed asap.
A recently learned this lesson
Fortunately it didn't damage my display. The battery sits right on top of the AMOLED displays (with its thousands of mosfets and delicate matrixs) in most phones.
I'm currently on Android 11, june patch. Just got the phone this week and noticed something very frustrating. I can generally "fast charging" as i only have a 15w charger for now. But sometimes if I unplug it and plug it back in, it just says "cable charging" i have other chargers and it's the same.. sometimes it says fast charging, but i downloaded Ampere and can see it only at 300mah and only goes up very slowly.. 1% every 4mins..
Anyone else with these issues?
Just try using the official charger and cable because everything else would be way dangerous. The same thing you have mentioned is happening to me as well. Try changing the way cable is plugged in. Turn it upside down.
Im using the 25w charger, Samsung original and neve chared with the stock 15w charger. It shows super fast charging, no problems here.

I'm just trying to reduce buying so many as i have so many spares from old phone that charge in just over an hour SOMETIMES And over 3 hour at other times! Frustration is even if i unplug and plug it back it, it never seems to go to fast charging unless i let it discharge a little. Winter here and it's cold so temperature of battery has been fine.

Temperature matters. Charging is an electrochemical reaction. Too low a temperature and fast charging will not engage. Charging below 72-82F can cause Li plating to form which will permanently degrade the cell.
Never attempt to charge a Li at 40F or less!
Best battery start temperature is 85-95F
Li's fast charge best in the 90's.
Below 60F fast charging may not engage and it will slow charge for the remaining cycle.
Fast charging will disengage around 80% and at 90% will slow even more. This is to protect the battery.
If the battery temp get above about 101F fast charging will disengage. At around 104F it will stop charging all together.
Cool battery as it approaches 99F with a fan and/or damp microfiber cloth.
At ambient temperatures above 90F cooling will likely be needed for fast charging.

I don't really work with Fareinheit, but after looking, battery is reporting it as around 29degrees when charging. It does seem to be more consistent the last 2 days, i wonder if it's because the OS was still trying to learn my usage. It still happens, i just need to unplug and plug it back in when it says slow/cable charging. But haven't tested it too much, so still unsure.
I am still waiting on charger, i'll keep this forum updated in case anyone else is interested.

Lol, i did. Temperature was fine.
I received my charger after i typed up message. I used it with super fast charging getting 3000mA from ampere app. Worked great unplugging and plugging it back in.
Tested using it on my s10 charger, and it showed up as fast charging, unplug, plugged it back in, cable charging only.
Went back to the 25w charger. It says super fast charging but hovers aroud 1000mA.
Can't get it to use high speed. Temperature at 28.5 degrees.
The only way for me, let it drain 10% and put it in the charger again to get 3000mA charging speed. The message that says "super fast charging" means nothing to be honest.

In what battery % range are you charging? It should draw closer to 4000-5000 ma at its peak fast charge rate with a 25w brick.
About 2%@minute when fast charging at peak rate.
Erratic fast charging can indicate a battery failure.
Any swelling is a failure. Replace immediately it this happens.
Other signs are deminished battery capacity.
Try clearing system cache.
Toggle the fast charging switch on/off 3 times.
Discharge until phone shuts down then charge to 100%. Some say to do this 3 times but one cycle worked for me to recalibrate the battery gauge.
Fast charging is a little b*tch when it goes south but always suspect a battery failure if this happens. A swollen battery can damage and destroy the phone.
Battery failures can happen at any time but are more likely to happen with degraded Li's.

In what battery % range are you charging? It should draw closer to 4000-5000 ma at its peak fast charge rate with a 25w brick.
About 2%@minute when fast charging at peak rate.
Erratic fast charging can indicate a battery failure.
Any swelling is a failure. Replace immediately it this happens.
Other signs are deminished battery capacity.

Thanks for the response, with the testing i've done, it's been 70% to 100% only.
i've been needing my phone for work, so i haven't had a chance to discharge it. Will try it this weekend.
Do you charge it back to 100% after a complete discharge with the phone Off or On?

At 70-100% you'll see much slower charging.
Li's prefer frequent midrange power cycling. It can extend their life by hundreds of full charge cycles. Example 40-70%
I rarely charge to 90-100% usually to 65-82%
I almost discharge below 30%, 40% or so being typical. Below 20% there's not a lot of usable energy. It also stresses the battery more when charging from a deep discharge state.
If you insist on charging to 100% at night at least slow charge it to reduce battery strain.

i drained it to 0% until it turned off.
After turning back on, i plugged in the 25w charger and it started charging at 4000mA and max 4750 for only a few seconds for the first 10% and after that, it went down and stayed around 3000-3500mA. happy for that for now. So thanks for your input.
Basically, to get fast charging/super fast charging, don't unplug and plug in a few times unless you have to as it will revert to cable charging, and then you'll need to let it drain a little bit (i found, around 10mins ) before plugging it in again to get the fast speeds.

Having the display on skews the charge curve, don't. It will charge slowly or not all if the display is on.
It you turn the display with it the battery page already open you have one or two seconds to see the display off mAh charging rate.
You can easily tell it's fast charging by watching how fast the battery percentage changes with the screen off.
1%@minute or less slow charging
2%@minute fast charging is active
Fast charging will ramp down depending on inputs like temperature and charge percentage the power controller recieves.
If it starts or goes under/over temperature fast charging will disengage for that charge cycle.
It also will ramp up/down sometimes throughout the below 80% range. This is normal.
Being in the optimum battery temperature range at the start and throughout the charge cycle is important but don't go too nuts. Higher is better than lower. Once the battery is below 70°F it will not fast charge as well (or at all) and/or can detrimental to the battery ie Li plating. There maybe other parameters the controller uses as well... not sure.
Oddly the Samsung 25w bricks are very tolerant of low input voltage. They will charge with as little as 60 VAC!
Like a few have said, fast charging like that will degrade your battery faster due to high temps, but the way you use it has a big impact on that. If you fast charge at those speeds to 100% take it off and use it constant until dead, and put it back on the charger then you will deff degrade it faster. Lithium cells need to rest between charge and discharge to let the the temperature settle. If not it's taking a hugh work load wearing down the internal resistance which drops the cells Mah rating.
Yeah, Im guilty of this too many times lol
Manufacturers know this as well but they know people want fast charging and largest battery capacity possible, they could at least make an option to lower the voltage down from 4.20v and a charger allowing us to switch between a few milliamp ratings..

You're correct it's best to allow some rest after charging and to not fast charge.
In practice this goes out the window
I do try to keep the voltage down as well as the temperature below 100F. Ambient temperatures here are frequently in the 90's
If I get a year out of this new battery I'm good with that.
However once it's down to 80% of its original capacity it gets replaced to avoid a failure. That's what happened to the original battery and I was lucky it didn't damage the display.
Below is my typical usage and the 10+'s fast charging patterns. The last charge ended with a near ideal battery charging temp of 94F. It fast charged nearly the whole time.

Jeez, had that app for a long time until about a year ago... I use AccA on a Rooted Pixel but id say I started using it a bit late.. You know none of this would be an issue if they still used replaceable damn batteries!! Lol My old Bar & Flip phones before color screens lasted days to over a week, and still had spare battery near by... My Startac even had a Solar panel battery

Yeah I have a flip top and S4, takes about 30 seconds to change the batteries. Most of the newer Samsung's aren't that bad to change out the battery once you know a few tricks. Some phones with multiple batteries are bloody nightmares though.
Solar panel? That's pretty funny
One way to limit phone usage.
How long it is supposed to take to fully charge it with 25W charger?
Are the first times you charge it slower to reach full charge?
The time will vary. Battery capacity, discharge state at start of charge and the battery temperature throughout the charge cycle.
Charging from 0-100% stresses the battery (especially with fast charging) and shouldn't be commonly practiced.
Battery start charge temperature should be at least 72F, 82F is ideal. Cool it if it exceeds 99F while charging. Charging is a electrochemical reaction and some heat is needed to avoid Li plating.
Never attempt to charge an Li near freezing temperatures
Li's thrive on frequent partial charge cycling. 40-80% is a good range.
Avoid going below 20% or over 90% except occasionally for best lifespan.
High temperatures and high cell voltage are Li's biggest lifespan risks. Avoid running the phone when the battery is hot (>102F) or provide cooling. Keep it out of direct sunlight especially when charging.
Store Li's in a cool, dry place with a 50-70%charge, not 100%!
GSMArena:
" We tested the Galaxy A33 with the said 25W USB-C Samsung charger, and it replenished 50% of the battery in half an hour.
A full charge took 1 hour and 15 minutes, and in fact, that was the cited expected time to full charge by the software as well. "
Fast charging will yield roughly 2%@minute from 0-80% if battery doesn't go into over temperature ramp down. Time it to get the nominal rate for that device ie how many seconds per 1% when fast charging in the 40-70% range, probably 30-40 seconds per minute when new. As it's capacity from degradation drops so will this rate.
Charge rate will ramp down at around 80%, then again at about 90% to protect the battery.
Temperature is the biggest variable.
If the battery is below about 60F fast charging will not engage for that charge cycle in order to protect the battery.
Fast charging rate not clear cut as the power controller optimizes charge rate per conditions and will reduce charge rate if they're not in the optimum range.
Constant erratic fast charging cycles with a known good brick/cable indicates a battery failure.
Any battery swelling is a failure, stop charge and replace it asap. It can damage or destroy the phone
Replace the battery when it reaches 80% of its initial capacity, the end of its useful service life. At that point it's considered degraded, degraded Li's are far more likely to fail. An Li can fail at any time... it can happen fast. Cataclysmic failures however are rare.
My new A33 came a couple of days ago with about 30% charge. I used it a bit lightly with the intention of depleting it(so I can have it full when I root it), I haven't yet installed the SIM, and when it was about 15% I got tired so I downloaded an app "Generic Battery Drainer" to deplet it quicker until it reached 0% and turned off, then I charged it to 100% with the charger I purchased which came today(an OEM one)
I didn't know that you should never deplete the battery to 0% and also did not know that the battery should not be charged to 100%
I obviously also didn't know the dangers of high temperatures, because the drainer app took the cell phone to about 104ºF
What prompted me to post my question actually was that from 0% to 100% charge it took about 3 hours. So I'm wondering if maybe I should check if the OEM 25W charger that I got does not charge fast as advertised?

You should fully charge a new battery before using. Are you using the cable that came with the brick? Is the wall socket wired correctly?
3 hours is far too long for fast charging.
Observe while charging to see if it's fast charging be % per minute.
The display must be off or it will skew the charge rate badly. Start and maintain it in temperature parameters described when charging.
If it drops out of fast charging because of temperature it will likely not reengage unless the cycle is manually started again ie unplug/ plug back in. Don't try to fast charge a hot (>98F) battery, it won't work. Cool the battery down and use cooling while charging. A damp microfiber cloth and/or fan work well.
Briefly turning on the display will not break the fast charging, it will resume once you turn off the display. Low current drain apps like Poweramp/bt can be used while fast charging but not high current drain ones.

I used the cable that came with the OEM charger that I purchased, seems to be identical kind of cable as the one that came with the phone.

Should be good to go.
When you get to 40%, try again... it's probably ok.
Try using a wall socket on a different breaker. Line voltage fluctuations won't effect this brick however neutral/ground fault might. Avoid using on a circuit with large induction motors on it ie microwave ovens, friges and A/C
