Sorry to be a nuisance, but I have a Baseus wireless charger installed in my car and all was fine and it did fast charging until it downloaded the UI 3.1 update.
Now the phone comes up with a ! in a battery saying that fast charging is not supported with this charger, so am a bit confused what's happened or changed, I like the fast charging aspect of it as it can put a good dollop of power into the phone on the way to work and I can also put Bluetooth on to link it to my car.
If it can no longer do this then I will need to change the charger.
So if this is the case, could somebody please recommend a fast wireless in car charger that will work with my S20+ 5G.
Thank you.
Interesting. I can't imagine wireless fast charging can be very fast, I was surprised to see the term.
Even Samsung talks about it albeit with no specs.
Samsung is historically notorious for bending the truth one way or another... you need to really scrutinize them carefully.
I wonder how "fast" it is compared to conventional fast charging with the 25w brick?
Apparently you're not alone and to make matters even worse the issue means no wireless charging at all to many of the effected users.
Samsung phones are having problems with fast wireless charging
The issues may have started with a recent security update
www.androidpolice.com
Best work around probably is to use cable fast charging and go for frequent midrange (40-65%) quick charges that only take 10-15 minutes but give enough mAhs to last 2-3 hours of screen on time. Li batteries love to be used like this and it can greatly prolong their service life.
Temperature matters; the battery needs sufficient temperature to support the electrochemical reaction properly.
Never start a charge cycle if battery is at freezing.
Avoid doing so if the battery is below 60°F
Below 72°F Li plating damage during charging becomes an issue and if it happens will permanently damage the battery's capacity.
Best start temp range is 80-90°F.
Fast charging* will not engage if the battery temperature is too low or high (approximately 100°F or higher).
Will disengage if temp goes too high as well when charging; first fast charging then all charging once it gets to about 101°F or higher*.
Best charging temp range is 80-99°F
*these charge throttling/auto shutdown values will most likely apply to wireless charging as well.
Thanks for the quick reply.
It's just that I find it most odd that this has only started to occur after the latest update, prior to that no issues whatsoever.
All I know is that when I put my phone into the holder, the jaws close and it normally says Fast charging: xx% and a estimated time to full charge.
A typical fast charge takes about 15-18 minutes which takes it from ~90ish% to 100%, I like to have the phone up to full charge before I get to work as I never know when I might get another chance to charge my phone off the mains.
Another oddity is that I have a Spigen wireless desktop charger and that does a fast charge without any issues.

Updates... destroyer of worlds.
Hopefully they will correct it and push it out soon.
Try clearing the system cache.
Double check settings.
You can try a hard reboot (not reset).
The associated apks for it are probably in Android services but clearing its data would cause a lot of work resetting settings and may not help at all.
If you did a major firmware update ie OS upgrade a factory reset is a good plan, otherwise it's likely a waste of time.
I'm now even more confused, this evening I put the phone in the holster/charger and it instantly initiated fast charging and topped the phone up in 15 mins.
I've tried turning on WiFi hotspot, no change, WiFi on/off and it still charged at fast speed.
Turned Bluetooth on no change. So I don't know why it's doing what it's doing. Weird.

Bought this tablet yesterday after finding it for a €50 discount and reading some reviews. The reviews warned that the charger is a but underpowered, and they weren't kidding, after 15 minutes of being plugged it I've only seen it go up 3-4%. Worse yet, if I try to actively use the device (just some browsing, nothing intensive), the charger can't keep up at all and the battery charge starts dropping again, slowly.
I'm quite happy with this tablet, it's got a nice feature set, good performance, decent price; I don't want to return it. But not being able to use the device when the charge gets low is a bit of a deal breaker. So I'm left wondering.. is there a way to charge it quicker? Would a 3rd party charger with higher amp output work? Or doesn't it work that way?
be sure being charging with original charger and usb cable
I was having same issue during the first month with this device, i was charging it with another usb cable (much longer) else than the OEM one, My device took 10 to 12 hours to do a full charge, very annoying thing. After some thinking and asking other ppl about this issue, tried to charge xtz with the charger and usb cable included in the Box and voila, not only the charging time has reduced to no more than 3 hours, right now i can use the Tablet without no intensive power requierements (wifi browsing with minimun screen intensity) and can see how the charging state increase during use... Hope this can help u.
Thanks for the reply! Sadly I'm currently already using the standard USB cable and charger that came with it, but maybe my cable is just fault or something. As far as charging rate goes, 3 hours sounds like what I'm getting, so maybe my expectations are a bit high in that regard. On the other hand it seems like I should be able to at least use the device when it's plugged into the charger without running out of battery charge (even if much slower). Almost seems like it's just being drained abnormally fast, but according to the battery usage thing, ~90% is used by my display which I guess is normal
Hi, I'm coming from an SM-930F and now have a SM-965F. I'm experiencing a strange charging behavior. I became aware of this when noticing that the S9 plus when connected to my Aukey QC 3.0 charger in my car via the OEM cable (screen on and GPS active) can only hold, but not increase the battery level. This was completely different with my S7 (same charger) which achieved an increase in battery level of 30% per hour, all other things equal. I now did some tests with a plug power meter and found that the charging current goes down immediately when the screen is switched on by roughly 75%. The charging power decreases from 6-7 W to 1.5 W. Please note that this is the gross current/power flowing from the wall socket to the device. With the energy consumption of the display, the net current flowing into the battery is negligible which explains the observation above. Interestingly, the effect is also present with the Qi charger, but to a much lesser extent (only 20% reduction of charging current with screen on). The S7 does not behave this way.
Has anybody observed similar effects or could check with his/her own device? Is this an intended behavior? Does this mean that - effectively - the S9 plus cannot be used while charging?
Best regards
Christoph
I have a USB multimeter and have checked several phones of mine.
This behavior is inherent to Qualcomm Quick Charge. I came to the S9+ from a Droid Turbo 2, both exhibited the same behavior.
Also i've never seen voltage spike above 9V, even though it's supposed to go up to (in theory) 12v (QC2.0)
Samsung support told me that this was not normal. I sent the device to them now. We'll see whether this will make a difference.

1.5W is waayy too low for modern smartphone, I'm averaging about 5W with the regular "cable charging" status.
I'm having issues trying to trigger the fast charging mode on my S9+ with the variety of QC2/3 capable chargers that I have laying around. Just bought a voltmeter to do more testing to see what's going on with these chargers.
I don't even get consistent result using Samsung's charger and cable, so I'm wondering if my port is jacked.
Samsung phones don't fast charge when the screen is on, but it shouldn't drop as much as you're seeing. It should work pretty much as the S7 did.
Hi folks,
I still have an issue with the charging behavior of my S9+ and, as time has gone by and I have collected some more information, I am seeking your advice again.
My problem is that cable chargin while screen is on is more or less impossible.
This is not about fast charging not working. I am aware that fast charging is not fully operational while screen is on.
But 9 out of 10 times my phone does not charge at all while screen is on when connected by cable.
However:
- Charging on QI charger with screen on is working.
- Cable charging with screen off (even with always on display switched on) is working normally (not superfast, but roughly 30% per hour which is ok for me)
- Even with screen on, status bar notification says that fast charging is active and gives "normal" estimated charging times. But the battery level won't increase over time (or only with very low rates).
I already tried various chargers and cables without any effect.
I resetted the phone for several times. I verified that the behavior described above also occurs with a plain phone without any Google or Samsung account or any other apps than stock installed.
Brightness of screen does not really matter (with lowest level you might get very slow (1% per hour) increase in battery life, with highest level it is closer to -1%/h).
I even sent it to the support where they told me they could verify and fix the problem --> without any effect.
I changed the phone. Unfortunately, the new one first seemed to work flawlessly, but showed the same behavior after some cycles.
Interestingly, sometimes (1 out of 10) cable charging with screen on is working at least somehow. Some days ago, I could increase batterery level by roughly 10% within one hour. But I could not repeat that.
I attach screenshots of GSam Battery Monitor which show that charging rate goes down as soon as display is switched on.
Do you have any ideas? How is your phones charging behavior while screen is on?
Best regards,
Christoph
I'm just speculating on this but I always was under the assumption it turns down the charging rate due to heat, having the screen on, GPS going, etc heats the phone. The newer models seem to be more sensitive to it and throttle back faster.
My dock sits on up on the windshield and it doesn't take much when it's sunny out for the phone to stop charging all together, it overheats when running GPS, screen on and the sun is hitting it. I need to find a new mount to move it lower down on the dash...
Thanks for your reply. I also suspected that temperature could play a role here. But I have not been able to verify that yet. Attached you'll find also battery temperature for the charging cycle shown in my previous post. I also let sit my phone in the fridge for a couple of hours before charging without any significant effect.
On the other hand, I find charging rate to be lower on hot, sunny days. Today, with cloudy sky, I could increase battery level by 4% during my 30 minutes commuting time. Thus, if there is a relationship with battery temperature, it's not a simple linear one...
I had to move my phone mount recently because of some changes I made to my car, previously it sat in front of the AC vent and I didn't have issues, now it's not and that sucker overheats and stops charging in no time when it's sunny out. If you can position it where a vent is blowing cold air on it, it should help.
Unfortunately it's already sitting there...
Hi,
I have a charger with a qualcomm QC 3.0 port and other regular 9V 2A ports, so I have the same problem when my phone is connected to QC port, but for some reason it's charging normally when connected to the regular ports.
My phone is the european exynos version.
Interesting, mine is the exynos version, too. I'll try to test a regular port, too.
And also good to know, that I'm not the only one with similar problems...
I have an Infinix Note 2 (X600)that have some charging issues
when i charge the phone i usually need to jiggle the cable a little bit to get the power flowing, but lately it gets much worse. when charging my phone need a lot of time to charge. The charger is not the original phone charger, it's a spare samsung charger i found lying around in the house. its usually works fine up until now. I checked the charging power in ampere app and i found that the charger lose charging power slowly over time. for example the initial charge rate is 900ma , the charge rate slowly decaying -10ma /5-10 second to a point where the charge rate hit 0ma. i could leave the phone overnight but instead of charging the phone it reduce the phone battery instead.
My initial thought that it's because the faulty charging port because i game while charging and janked it fairly often. and ideas of what causes my problem or a fix ?
second question: is charging ports of micro usb android is all the same ? or it's different per phone model, cus im thinking to get the port replaced
Long story short. Use the manufacturer recommend,if not the original.
Yes they will mostly work, but when you take the cost of the device into account....
There should be information on this within the website for the smartphone etc.
Ironically enough, my battery died while I was typing this and I was running a GSAM bat test using always the original charger.
In logics term's, you can always start a car with a much cheaper battery, but when you're taking into account of longevity over quality and anything else you can throw at it, all roads have intersections...
Please email the manufacturer, things not the 90s so you will get better support [emoji12]

Got this device around a week ago and I'm finally daily driving it. I've noticed a big issue though... I can't charge the device past 80% when its turned on. It stops itself from charging it seems like. I have to turn off the phone completely, and plug it in when powered off to get it to 100%.
Is there a setting I have checked or something? maybe a Kernel Tweak I don't know about that could be causing this that I could change/reverse/modify?
Thanks!

Turn off optimized charging.
ohhhhhhh. Epic. Thanks
It's not a good idea to charge with screen on especially in high temperatures or in direct sunlight. You can cause hardware damage like this... auto thermal shutdown may not engage fast enough to save the device.
In general charging while using skews the charging curve, increases charging time and battery stress. These phones have a fixed heat sinking capacity which cases and glass screen protectors further compromise.
Constant operation with battery levels near 100% will impact battery longevity noticably.
Keep watch for any signs of case bulging. It indicates battery swelling/failure. Replace it immediately if this happens. Other signs of a battery failure are a sharp drop in capacity, erratic fast charging or failure of fast charging to engage. A swollen battery can destroy the display.
The risk of a thermal runaway event increases exponentially with a failed or degraded Li.
Replace them when their capacity falls below 80% of new to avoid a failure.

99.9% of the time I'm charging, the screen is off and I'm watching tv before bed. I'll unplug at 100% and go to bed. I also won't plug in until I'm under 15%.
I work in cell phone whole sale and repairs, so one thing I understand well is taking care of a device.
But, disabling that setting recommended above, it still stops charging at 75% entirely and never goes to 100 unless I turn it off entirely

If the screen is on it may not charge at all.
This is normal.
Cycling the battery like you do stresses it and will reduce its lifespan.
Li's like frequent mid range power cycling.
Not under 30% or over 80%
If it didn't use to behave like this the battery may have degraded. 1-2 years is a typical lifespan for a heavily used Li. Approximately 200 full charge cycles.
Replace when it degrades to less than 80% of its original capacity to avoid a failure.
This phone has only been out since January 2021, so its not a batter degrade issue. Plus, it was pulled brand new out of the box like this. You also didn't read what I said. I'm not using it while charging at all. Its sitting on a table next to me while I'm watching tv or gaming on my PC/Switch. I'll check it once in awhile to see battery percentage and it will stop at 75%, then discharge as if its not plugged in at all. I have to turn the phone OFF COMPLETELY to charge it to 100% once I get to 75%
I'm assuming software issue. when I had GSI roms on the phone, it worked fine.

Li batteries can fail at any time.
Symptoms; diminished battery capacity, erratic fast charging. Any signs of phone swelling, usually the rear cover is a battery failure in progress. Replace immediately.
If the phone is drawing more current than the charger and/or the power controller can supply, it will drain the battery.
It may be a software, firmware or hardware issue...
Check all settings, disable all power management. Enable fast charging (toggle on/off 3 times then leave on).
Clear system cache and do a hard reboot.
Return associated updated apps to their factory loads.
If you did any major firmware (OS) updates do a factory reset.
A defective/improper charger or cable; try known good Samsung charger/cable.
Defective C port PCB.
A failed mobo.
Time to send it in for service or replacement.

It's a standard OnePlus feature at work.
Hey Guys,
Anyone else experience slow to almost non existent charging speed if the phone has been on for a few hours?
The only way it goes back to charging fast is if I restart the phone while its plugged into a charger.
I have tried using the stock charger and aftermarket ones and different cables as well. Makes no difference until restart.
Chime in if anyone has any idea whats happening and/or how to fix it.
PS: I am unlocked and rooted if that matters.
Is the screen off? Having the screen on during charging will skew the charge cycle.
Does it charge normally when shutdown?
Possible battery, charging port, or mobo failure.
Check phone for any signs of battery swelling.
Same issue here. Got the phone today, charges sloooow by USC-C as well as QI... Although it shows "fast charging" in settings. I will check, if it's better after a reboot.

Doesnt matter if the screen is on or off, I even left overnight and gained like 8% charge.
Battery seems to hold a charge fine, there is no swelling and discharge behavior is normal. Used to charge normally a few days ago.

SOT has it diminished significantly?
Charging at a start temperature above 72°F?
If so it sounds like a charge port or mobo failure... sorry.
Try clearing the system cache and a hard reboot.
Try toggling fast charging on/off 3 times.

Ill have to check the temp next time I am at room temp. I was playing some COD so I was over 80F when I started charging just now. Did not have to restart so maybe its good.

Make sure the port is clean and free of debris.
Inspect and carefully clean* if needed with a toothbrush and a small amount of anhydrous isopropyl alcohol.
Lol, RO water if needed than the alcohol.
Allow to dry completely.
*I live in a dusty environment and even after 2 years never had to clean my C port. However my bdu cargo pants pockets are lint free, not all pants pockets are. In general these ports seem to stay clean but you know how that goes...
Same here. Did someone find a solution?
In my case it just normalized itself after a few days of usage... strange thing was, that the slow charging affected both, usb and qi charging.
Glad you fixed.
Btw maybe intelligent charging. If phone can't detect a time where you don't use it it have problem adapting charging speed. If you change everyday the moment you put it on charge better deactivate that option
If I may continue this thread, I have another question about the charging. Is it possible to disable fast charging?
I only charge at night so I don't need my phone to warm up from quick charge. On my old Samsung Galaxy Note 9 I could do it, but now I can't find the setting.
Thanks.

The only harmful part of the charge cycle on this phone is the top-off, and you can adjust that. You could use a 5W charger but I doubt it would extend the life.
More beneficial is checking other threads for features that may drain (add wear to) the battery.

Simply use a 12 watt or less brick.
Fast charging needs a compatible 25w brick and cable (Samsung). In most phones it has to be enabled. Disabling fast charging is easy... enabling it sometimes is not

The whole point of having a feature is to use it when needed. If I am in a hurry I want to activate 30W charging with a single toggle in the settings. I don't have to bring two different power bricks, one 5W, one 30W, and manually switch between them.

you should get a new phone it's the only way to fix it because it's broken and you can't fix it when it's like that.
