Anyone else using wireless charging find that their s9+ is always warm when you pick it up now that android 9 has arrived? Even if the green light has been lit for a long time claiming it is fully charged, it still is always warm when I pick it up now. It never seemed this way on android 8 (in fact the phone often made me wonder how it managed to feel colder than ambient when I picked it up previously).
Every phone gets warm when wireless charging, the s9 has 10 watt quick wireless charging so it'll get even warmer than when charging at 5 watt.
But I have the exact same s9+ and Pleson fast charger I had before the android pie update, and it is always warm now, even when it claims to have been fully charged an hour or two ago. The only thing different is android 9 installed.

I have my phone sitting on the Samsung wireless charger at work while tethering. I noticed that the phone stops charging at 100%, and the charger starts to flash blue. I am assuming this is to prevent overcharging and such, which I am fine with. My problem is that it never starts charging again unless I pick the phone up, and put it back down. Why is that? Why would it not start charging again when it dropped to a certain %?
Thats exactly what I want, it's better for the battery!

yea, but if that happens and say the battery stops charging at midnight, if it stopped charging, by 8am, it could have lost 10% or so , or even more.
not a good system if you ask me.
Maybe it's the wireless charger? I put my phone on the dock at 20% every night and I've been waking up wth it at 100% every time. My light also doesn't flash blue when it's charged, but stays on a solid blue.
same with me,when i put down the phone is solid blue no blinking for me,and when its charged lights up green and stays green as the LED on the phone.maybe your wireless charger has problems.

I agree. I have a RAVPower charger and the thing keeps my phone at 100% all the time. I have been known to get on long phone calls with my bluetooth headset and I just plop my phone on the wireless charger. When I am done, the battery is still at 100%.
We don't always have that luxury.
I bought the wireless charging back-plate and a few charging pads from Samsung for the two S5s we had in the house, and they did the same thing. 100% repeatable.
When the S6 Edge did it too, I just expected it. Does it with the "old" pads I bought for the S5, and the new circular ones (that I just got yesterday) too.
My kids' Lumia 929 phones do not manifest this behavior, so it is my belief that it is phone specific.
I got exactly the same problem... In the middle of the night my s6 edge is completely charger (100%) and the charger stop in this moment and my solid blue light is turn off.. When I take my phone in the morning I have 90% or less battery some time... My wireless charger is Samsung Brand... Was a gift with my s6 edge... This situation is terrible for me...
S6 Edge SM-G925i, Telcel, México.
The same way some phones show some problems I do think that same wireless chargers are showing problemas, because as I've been telling my original s6 round charger sticks with the blue light on all night after the phone charges at 100% and it happens the same thing with another charger that cost me 3£ so it's a charger thing in my opinion. Because my chargers always worked with s5 great and with s6 as well
Hi dear v10 users. im here with a veird question again.
I was looking my FB group about v10 and some 1 Claims that: He was charging phone around 45 mins till some 1 use his charger to charge some other phone. since then his phone charging around 90 mins. . And yes i got same stuation. My phone charging around 90 mins and yes some 1 used my charger also. so that can be true ? 0o ?? if our original charger get used by some 1 else does it effect charging speed? btw it still says " fast charging " during charge.
Ty for answers.
Idk but my V10 doesn't charge NEARLY as fast with the stock charger as the Qualcomm Quick Charge compliant charger I have in my car. I've tested other phones on it too. Nexus 6 for example, it'll charge at a nice fast steady rate while I'm using the phone. If I perform the same scenario with the V10, it'll hardly move 1%. Real talk. Idk what the issue is.
Sent from my Gold and Black V10
I came from the nexus 6 myself. Not only was I disappointed when I noticed there appeared to be a noticeable difference in charging time but I didn't understand why. Here's what I know, the v10 utilizes quickcharge technology however it only activates when the main screen is off/dormant. Unlike the N6 that quickcharges regardless. Sorry to be the bearer of bad news...?

Well i have given my charger many times to different people and did not see such behavior. About the screen on/off - i can't comment because when i charge the phone i usually don't use it anyway but it does not seem too logical. If you use the phone during charge it will have much higher consumption than when sitting on your desk so it is normal charge to take longer time this way.
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 a Qualcomm 3.0 car charger which was worked with my older phone Samsung S8Plus and charge without any problem
Now I have a S9+ and it's not charging . Notification said it's connected to quick charger,but it's not charging just keep same battery level all the time and I am driving 45-50 minutes every day
Any ideas what it could be? And how to fix that.
If I'm running Waze and have the screen at high brightness my Samsung fast charger has trouble keeping up too... It might charge a couple of percent per hour but that's it.
Dropping the screen brightness a bit allows it to charge a bit faster.

I use Waze and Internet Radio app in split screen, my brightness is like 55% not auto
Today I disable fast charge and no different so far.
These phones seem to have sensitive heat throttling, mine charges slow when running Waze and music at the same time. Try placing it in front of your AC vent and see if keeping it cool speeds up charging.

Well mine is right in front of the A/C grill
Will try to use different charger today
Not sure what would be causing it, but there should still be no problem with it keeping up. For reference, I run my 9+ at auto brightness in the car, running Torque Pro, Waze, and Pandora full time to work and back, 40+ minutes each way. I have a Verizon branded charger that I got with my V30 back in Nov, and it has no issue not only keeping up, but also charging it up. I easily get a minimum of 15% or more charging just in that time.
I order me another charger . Will come in couple days . Anker 24W ,3.0
That one according Android Police one of the best chargers for our phone. Will see
Got new charger Sunday and try right away
That one :Amazon.com: Anker Quick Charge 3.0 24W USB Car Charger, PowerDrive+ 1 for Galaxy S7/S6/Edge/Plus, Note 5/4 and PowerIQ for iPhone X/8/7/6s/Plus, iPad Pro/Air 2/mini, LG, Nexus, HTC and More: Cell Phones & Accessories is working great
Dear XDA,
So this phone has been flawless for me, no issues what so ever, I could even get up to 7.5 hours sot on this phone, I have no problem running heavy apps like games, emulators, terminal, linux containers, 3D apps, benchmarks, etc, etc.
So the issue is with the Samsung OEM tabletop flat wireless chargers (this was released back when the S7 Edge and Note 7 were released). Recently I have noticed it will stop wireless charging (and flash the blue led on the charger itself) and won't charge my S9+ no matter how many times I replace it. It happens at certain percentages to (i.e it will charge fine to 80ish and then it would stop). For testing purposes last night I took the phone out of my Spigen Hybrid S case and turned it off and put it on the charger. It charged fine! The next morning I turned it on and did some notification checking and then before going to freshen up I put it back on the charger to top up. It would not charge past 98% at all. Same issues. I then just plugged it in and got back to 100%. Curious as to why this is, I took my old S7E and plopped it on the charger, its been charging fine. What could be the issue? This issue has only been popping up recently?
Edit: Seems to me the s7 edge did the same to, just checked and it stopped wireless charging around 92% percent. I noticed if I kept on replacing the phone, after some time it will continue charging but then stop again.
