Question Fast charging not working anymore - Samsung Galaxy Z Flip 3

Hi everyone
After two weeks of use, fast charging doesn't work anymore.
When I plug the cable, I can see in the AOD screen the "fast charging" message and the time left (let's say as example, 46 min).
But after one or two minutes the "fast charging" disappears and the expected time left increases to 1 and a half hours or more. Sometimes it takes almost 3 hours to charge from 20 to 100%.
I made sure that fast charging is activated in the settings.
I tried with several combinations of chargers and cables and even with portable batteries. It happens with them all.
Did this happen with anyone else?

Have you made sure the charging port is clean? It could also be loose, but the easiest way to test is also a horrible idea.

Update:
Oddly enough a reboot solved the problem.
Everything is back to normal now with fast "but not so fast 15W" charge.
I suppose it was a software bug.

Let's be real. 15w will never be "fast charging" no matter what Samsung's marketing team says, but I understand your concern

Samsung's marketing team didn't create the standard, though. It's faster than standard charging, much like 25W is called super fast and 65W is called hyper.

Sorry but I expect my modern smartphones to come with 25w as a minimum. Had a OnePlus 9pro before this and the charging is sorely missed

The Note 10 added 45W, only to drop back to 25W on the 20. At 25W, the charge from 15 to 100 was about an hour and 15 minutes. The charge from 15 to 100 on a Z Flip 3 is about an hour and 20 minutes. You lost 5 minutes.
Throwing 45W (or even 25W) at a tiny 3000 mAh battery in a phone that's folded in half is asking for a fire. Google Note 7 recall. You'll understand why Samsung would rather risk any whining objections be made safely.

Fast Charging?!?

Hello.
Can someone explain me how on earth does fart charging works on this device?
I've tried the included cable and charger, third party chargers and i don't see any fast charging going on?!? or any indication on screen that it's happening.
I've read somewhere that you need a special cable to use with the included charger (?!?!) is this true? where do you get this cable?
Phone is amazing but the charging part is really is really weird if you ask me.
Thanks.

do you get any message saying fast charging?
it doesnt show any fast charging message, so i wouldnt rely on such a message to make sure its working. just use the included cable and charger and ull be fine it takes about 2.5 hours to charge from 0-100% via fastcharge

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol
Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00
trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.
I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.
Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.
i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...
Sent from my Huawei Mate 8 NXT-AL10 using Tapatalk
Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.

quick charge 4.0

They added qc4, but it's more like qc3 with just 18w(9v 2A). I hope a kernel mod will allow the phone to get 27w which will charge the phone completely in approx 1h 30m to 1h 40m rather than 2h 15m with the 18w charger.
Whatcha think nerds?
I think that's a bad idea as they will have specified a battery suitable for 18W charging ...
Battery should last for ages, anyway. It's 5000mAh, very close to pure AOSP, and the display is by no means large.
If you endlessly play with the camera motor, it might drain a bit faster, but otherwise, I suspect this will have the best battery life of any phone in the small flagship class.
I'm fine with QC3.0, since I've used that a lot.
But if it does come with QC4.0 then I couldn't be more happier.
With the battery capacity it has, I don't think I need to charge it all the time so QC3.0 is something extra for me.
The sustained speeds should be higher due to the battery size but I wouldn't personally want to risk modding the charging speed. Sounds like they made the insulation layers pretty small to get the capacity at the expense of charging rate.
My main concern is how well it sustains the speed and the temperatures (QC4 should be decent in that regard) because any maximum speed will drop off a cliff when it gets to 70-80% anyway.
Does it have 4.0 or 4.0+? I've seen some spec sheets saying it has 4.0+

It's really difficult to even find data on what the difference of those two are in real world scenarios. If I'm not mistaken the + version requires two PMICs (whereas it sounds like it was optional before) and I think the Zenfone might just have one. Asus themselves advertise 4 without the plus. If you ask me, Qualcomm should just have called it 5.0 to avoid the confusion especially because Qualcomm's own marketing material is very vague on this.

I'd be surprised if the battery didn't get dangerously hot if it's done.
The separator wall of cathode and anode on a battery that can handle faster quick charging would need to be thicker.
Asus chose 5000mAh with a smaller separator to keep size down. In the same size, ASUS could have chosen, like many others have, to have gone with a ~4000mAh battery with a thicker wall to support 30W+ fast charging.
It comes down to trade-offs based on physics. I'm always game for experiments though
Did a very little test. on org charger and cable
Battery on 65% did give 7,5 Volts and 1,65-1,70 Amps
Hello, today, I bought this phone and I plugged it into charger for the first time. However, in my opinion, the phone warms up relatively high compared to my previos samsung S8+. Have you got any experience whit this? Maybe I am too much perceptive and it's normal. And maybe it is the difference between Quick Charge 2.0 (s8+) vs Quick Charge 4.0 (asus)

The difference between quick charge 4.0 vs 4+ is that 4+ is compatible with USB PD (power delivery) which is the fastest charging standard, its what i think OnePlus and Samsung use for their tech. 4.0+ was revealed in 2017 a year after 4.0. It's lame but unfortunately Asus's zenfone 6 current batches do not support 4+ (however 4+ charging is still backwards compatible with 4, 3, and 2.0, that's why when @MishaalRahman tried their QC4+ 27W charger it didn't charge any faster, it just downgrades to 4.0 charging speed)
there's a chance a refresh of Asus's zenfone 6 may happen with 4+ release. Doubt it..but who knows
4.0 is still supposed to charge faster than 3.0 but I personally don't really see that increase in charge speed. Could be because of the size of the battery but either way I'm still happy with it because the large battery just means less charging (for me personally) since I just mostly do google searches and text, and once in a while use snapchat/ig. Its the perfect phone for me, I bought it yesterday to replace my Pixel XL (gen 1).

Warp charge slower than advertised

Hi,
for me, the charging speed varies between 50 and 75 minutes for a full charge. It says warp charge 65 on the lockscreen. Any idea, what might cause it being slower than it should be? I am on OOS 11.0.4.5.
Thanks
Mine actually charges faster than advertised. It charges from totally discharged to fully charged in 35 minutes with the phone turned off.

Check to see if you have optimised charging enabled. If you do then that slows down charging.

Thanks, it is switched off. Do you know how much current is used when charging at about 60%? According to 3C, it is between 1,800 and 2,800 mA. Only once, I have seen about 6,000 mA in a similar situation. Somehow this looks rather random to me.
Warp charge is as advertised for me. Any other charger is extremely slow. Gsam shows I'm at about 3400 while charging from 60-70.

I stop paying attention to the current because in the end it doesn't matter what instantaneous current I am seeing. I always see it starts with 5500+ mA for just a few seconds and drop to 3000+. I ignored it and just let it charge (phone on, screen off).
I usually charge from 2x % to 90%, and it takes no longer than 25 minutes most of the time. Averaging 2.5~3% per minute.
Usb cable or usb port of your phone might be at fault.
My 8t takes less than 40 mins even with optimized charging turned on.
Because my phone says Warp charge 65, I do not think charger or cable are broken. I try to avoid uncharging my phone to a low level, so I cannot tell how long it would take from empty to full.
The other observations are like what @zellleonhart is describing. I had just wanted to rule out hardware issues for a new device.

That used to happen to me. 65w would only happen for some charges and other times it would be slower taking over an hour to fully charge. Now it charges fast every single time in 40 mins or less. Not sure what fixed it but I have a t mobile variant converted to the latest eu 11.0.5.6 and optimized charging off. I don't always charge full but the first 15-20 mins being fast seems important imo since that can be done after waking up and getting ready
I think we are all forgetting that we aren't charging one 4500 battery but actually two 2250 batteries at the same time. It legitimately charges from 0-100 in under 40 minutes, I've tested it. The problem is it's not compatible with any other charger I've tried. Quick charge 1,2,3,4 or PD or even the warp 30 from my OnePlus 7 pro. Any other charger I try is like plugging it into a computer and would take 24 hours to charge. OnePlus definitely messed something up and really needs to fix it soon.

My original observation (and this was confirmed by multiple people now) was that using the original charger and cable, charging speed varies a lot and only sometimes had cuurents for a few mins, which could charge in 40 mins if it would be constantly at that rate.
Your comment about slow charges using other chargers unfortunately is very true. I have tries lots of combinations (chargers for Macbook Pro, Xiaomi phones, older Oneplus chargers and cables from 3T) and the fastest of these would need about 3-4h and the slowest about 10-12h (estimates based on current).

My phone has charged at the advertised speeds every single time I've ever plugged in the warp charger. It charges my phone everyday from 20%-80% in 18 minutes. I've charged it from 0-100 in 38 minutes.

Since I did that, the charging speed was always as fast as Oneplus states.

No. Haven't used a custom kernel on this phone yet.
Just tried the 30W Warp charger of my OP3T again after installing xXx_NoLimits and now this is also charging relatively fast. Estimated full charge time is 1:35.
And yes, I understand that for some folks the full speed has always worked
This is the absolute best warp charge magnetic cable I and my friends have ever used. Been using it for years now. Both warp and dash changes and better yet. None of my phones have charging port issues ^_^.

General Well. This is a bit disappointing

S22 Ultra 45W vs S22 Ultra 25W vs S21 Ultra 25W charging test
wouldve expected it to charge much faster, especially when you consider the smaller battery.
Totally expected, 45W works just at lower temperatures and under 50% charge as it was back in the Note 10+ days. It's useful only when you are topping up on the go, for 0-100% it's almost the same

Well it is improved, it was downgraded 2 years ago to be fair and now is back to that state. It charges faster from 0% to 50% which is exactly how it used to work before. If you expected something different your expectations were wrong, don't know what to say. Even devices with very fast charge charge faster for the first half then slow down considerably. Samsung has always had a more conservative approach on charging after the Note 7 debacle, that's why I expected it to be managed like it was before.

I've traded my Oneplus 7 pro. A 3 year old phone and It still charges much faster than S22 Ultra. Considering to I'm paying for a flagship phone which is over £1000 and it's charging technology called "Super fast" charging. Yeah I'm a bit disappointed.

The N10+ with the 25w brick will fast charge from 5-70% at the rate of 2%@min on its 4300mAh battery. Between 70-82% it may ramp down slightly, at 90% fast charging disengages.
This is dependent on battery start charging temperature, if too low or high fast charging will not engage, and battery condition. A 20% charge in 10 minutes isn't bad...
Fast charging is limited by heat buildup in the battery caused by internal resistance. The Li cell charging process is actually an endothermic reaction but is outweighed by the internal resistance generated heat.
I can see it being an issue for those that prioritize fast charging over battery longevity. I charge my device overnight and use a Chargie to regulate the charge to a maximum of 80% and limited to 8 watts. I'm not a power user and this method may not work for everyone.
Looks like they're using an older 45 watter. The new ones are the real 45 watts.

I heard that was the case. The old 45W charger throttled, making it act like a 25W charger. The new one has PPS and is PD 3.0?

The old 45 Watt averaged about 28 watts of power iirc. The new one will supposedly give the full advertised wattage. I'm just shocked sammobile out of all sites did not know this...

That is shocking. Do you think the new charger will output less heat to the S22 Ultra because of better efficiency thanks to PPS?

I doubt it. QC boosts the charge wattage by increasing the voltage; more volts less amps means less parasitic waste heat.
What's left to improve on the charging protocol side? They to improve the battery itself now for any meaningful performance improvements.
These manufacturers push the hype, the reviewers do too, then long after the release the truth finally comes out.
If you can wait a few months for the dust to settle you'll get a better idea of what to expect.
There is a new 45w charger, model EP-T4510XBEGGB. This one seems to work fine and not overheat.

Curious as to what your thoughts are regarding the Chargie since Samsung has now added the same charge up to 80% feature in Android 12 under device care. Is it now redundant?

And of course that one is sold out everywhere lol, this happens everytime sammy launches a new device. All the accessories are never available, pretty bad they cant get this right its so annoying for us early adopters.

i have those USB-C cable with watt LED display. it only showing 31w on my home 65w aftermarket charger,
also showing only 31w on my 65w aftermarket car charger.
I'm using my OP9P charger lol it works really fast so...I didn't need to buy a separate charger. Thank God since it's sold out

Question Help with the charger - Problem

Hello!
It's been a while since I don't have an Android device (Iphone user lately) and I'm buying this beauty these days.
I have two questions: First, right now the 45w charger is out of stock so should I buy the 25W instead just until I find the best one (expend money).
Two: How shall we charge this device? All night? Just 2 hous like Iphone? Please help me out on this.
25W vs 45W is really just a matter of the time it takes to charge the phone. And right now, available evidence suggests that its not worth it. As for how to charge it? All night is fine, as the phone will stop charging the battery when it is fully charged.
does the phone will stop charging the battery when it is fully charged?

Yes, that is always the case.
I would recommend buying a 45W (or higher) USB PD PPS power supply. That will work on Samsung devices. But keep in mind: it has to support PPS to allow voltages between something like 5V, 9V, 15V etc. If it is only USB PD, it will only charge at 15W.
I have the Anker Nano II 65W that has PPS, but there is also a 45W version. But that is just one option, there are plenty of other products out there that support 45W USB PD PPS

LAtest equipment come with a battery health function it basically charges fast up to 80% and then slowly charges the remaining 20% to extend battery life. Once at 100% it won't charge at the same level, reducint the current/voltage.
I really don’t want to damage the battery like it happened with my iPhone (1 year and 89%).
That’s why I’m asking!
Please post your own experiences.

The worst thing for mobile phone batteries is heat. So running the display all the time and gaming are probably the things to avoid. Which unfortunately...Is what most phones are being designed for these days. So don't let the phone get hot, and try to keep the charge level under 80% if you want the battery to really last. But batteries WILL degrade. There is no way around that. The best you can do is try to limit the damage.

Two things kill the battery: heat and high/low voltages
In an ideal world, the Li-ion battery is at around 20°C and stays at around 3.8V.
Use the slowest possible charger whenever you can (5W e. g.)
Avoid fast charging as often as possible
Don't charge past 80% and don't let it drop below 20%
Don't let your phone stay at 100% for too long. Nothing will happen but the high voltage will degrade the battery (like if you leave your device plugged in every night).
In theory you shouldn't charge your device when it's hot and so on but I mean if you live in Spain for example and it is summer. What else are you going to do? So avoiding charging the ambient temperature is too high, is something you can't really do. (Yeah, in Spain most homes to have AC but you get the point )
I have taken care of my OnePlus 7T Pro's battery since I have received it 2 years ago. According to OnePlus Diagnostic it started at around 97% health (new device) and is now at 93%. I almost never charge above 80% and have a Tasker routine to only let it stay at 60% over night and charge to 80% right before my alarm rings. I use ACC (Advanced Charging Controller) for that. But it requires Magisk.
That might be a bit extreme but I have only lost 4% after 2 years and countless battery cycles. Keep in mind that every now and then you should go from 0% to 100% to let the system calibrate the battery so that it accurately reports its charge. This is the only reason why you should do this so that the system knows how much capacity the battery has. And if you mostly stay between 20–80% all the time, it might think that 80% is its max charge and start misreporting the percentage.
Thanks for all that great tips. I think I won't ever buy an extra fast power charger, I'll use a normal one...
is it safe to use 25 watt charger of s 21 TA-800 for charging s22 ultra?

yes, enable fast charging and limit to 85%
