Phone gets really warm on Samsung fast wireless charger - Galaxy Note5 Q&A, Help & Troubleshooting

Hi
I just got a Note 5 and a fast Samsung fast wireless charger stand. Everything looks good except for the fact that the phone gets quite warm after 100% (when the light turns green). The highest temperature it has hit is 43 C. Normally it would hover around 41-42 C. This means that the phone battery would be subjected to such heat around 4 hours every night. Should I worry about this? I live in Singapore.
Thank you.

please share info about your phone :
stock or custom rom (which?)
did u install battery app??
do u have this problem when connect usb cable directly to your phone (fast charge )?
if in your note 5 put on case or other things put it off and test
note 5 will be warm in fast charge until 90 % (not 100% - it's problem)
i suggest if it possible work turn off fast charge when put your phone in charge in night
or reset your phone and test again.

Stock ROM. Marshmallow 6.0.1.
No battery app. Fast charge via cable works awesomely.
It still gets warm even without the case. I tried resetting my phone, and it's ok. It's the same for normal wireless charging.
So 42 degree Celsius is bad?
Anyway with my new case I need to enable daydream to make sure that the wireless charging doesn't stop after the screen turns off. I set my daydream picture as a solid plain black picture. So by right this shouldn't cause any damage to the screen right? Only the screen touch sensors are working overnight.

My stock 64 gb N920T on MM routinely gets to ~37.5 C (99.5 F) while using the OEM charger with fast charging turned off. It's gotten as high as 39.5 C (103.1 F), which was the first time I took readings using the GSAM Battery Monitor Pro app.
I wouldn't be surprised if the wireless fast charger pushes the temps past 43 C (109.4 F).

tilt battery charges slowly.

Within the last few days I've notice that my phone is charging at unbelievable slow rate via the wall charge that was supplied. I usually get a full charge in maybe 1-2 hr depending on what percentage the battery is at. Once it is fully charge it hold the charge, but when it drains then it would take like 6 hrs to do a full charge. I've tried to soft reset it to see if the percentage goes up, but it stay the same. I turn off the phone to let it charge, but it still charge at a slow rate. I'm wondering is it time to purchase a new battery.
What do you think? And is there any other test I can do?
The slow charge could be one of a few things... One could be the battery as you suspect (and probally most likely).. Also, are you chargign the phone in a diffrent place? If the battery gets too warm from lack of circulation, it will not charge (or just charge much mroe slowly).. It also could be that your USB port is starting to go... IF you have a stand alogn abattery charger available for it (like one on a docking station) try to charge it on there and see if it still charges as slowly.. Another though could be if you are charging it in your car while using GPS or Wifi.. IF those are left on, they suck down the battery a lot faster and thus it uses the electricity as fast as it can pull it in.. I woudl suggest powering the phone down while charging.. that could also help...
i always charge it in the same spot since i got the phone. i dont have a dock charger. its weird last night i was at 49 and i turn off the phone completely and plug it in. woke up today the orange light indicating that it was charging still was on. turn on the phone and it was at 55 percent. WTF!!!!!!!!!!
I guess that touch pro 2 better come out soon.

i have the same problem. Its either your USB port or the charger, so simply go buy a new charger and if it still does it the port is bad....if not, problem solved
or put it in your computer to charge, that avoids buying a new charger.
usb charging is always slower then wallplug charging as usb can only provide
5v * 0.5Amps == 2.5Watt
where
wall charger can provide as much watt
as the charger is made to
but of cause the pda will only draw as much
amps as it was made to support

Charging time.. ?

I had problems with my phone, discharing in under five hours, and useing 5-6 hours to recharge..
When I got to work today, I exchanged the phone with a new one.. It was at 25%-... Small use, and it was down to 14%....
Now Its been 7 hours, and its back to 69%.. and still charging...
Anyone else having this problem?
I experience sort of the same thing...
Charging the phone takes forever (4-5 hours) and Im down to 70-65% charge when I get to work after a full nights charge (from 100%). On the way to work I listen to Spotify (no streaming) for 30 min, read a couple of emails... but nothing else...(wifi off but push mail on)
My conclusion was that I used a USB port for charging and my USB port may not delivering a lot of power (ie long charge time, but this was not a issue with other phones on the same USB ports).
I have also read that the battery charge "builds up" after a few recharges, but I have not experienced any difference the last week.
I will try to use the charger tonight (not USB)
The non-USB charger will be faster since it delivers 1 A. If I remember correctly, a normal USB-port only delivers 100 mA - so it should be 10 times faster
With the normal charger from LG.
0 til 100% goes in 2/2.5hours.

That must be USB charging.
From a wall socket I get 10% / 10 mins - 100% charge in ~100 mins.
USB is restricted to 100mA if the device doesn't "connect" to the USB port (identifies itself blabla)
If it does, standard USB is rated at 500mA for each port.
I recommend using the wallcharger, as those usually deliver more juice.
Its not USB charge.. Connected to the "socket" in the wall...
I just noticed on the phone that battery condition is "overheated"....
This is the second phone I have with the same problem.....
oh.. and btw;
ive was done at work at 4pm, battery at 69%..
Now its almost 7pm, and its down to 25 %
Non USB charging from 4% till 100% 2 hours

That's probably bad... unless the fuses in your house (charge at home) are bad?
Way, too slow and it should not get hot.
I put the phone in "Airplane" mode, and now it charge fast, and keeps the power/current(?)...
Since WiFi is allways disabled, it most be the phone connection that draws all the power out of it....

Plus you get free airpoints!
Experiencing some issues with charging too.
Under heavy load (for instance 3D games), even if my phone is charging with the wallcharger, my battery slowly discharge and my phone eventually shuts off automatically
I also noticed that my phone can get really hot. I had this issue with MCR fr8 and fr12 with and without calibration. No overclocking or fancy kernels. I'm now considering sending my 2x back to LG with an insult letter.
Anyone experiencing this issue as well? Any clue how to fix that (wallcharger > 1A for instance?)
Supposedly the 2X has an issue with Radio usage. Using only 2G networks will improve it alot.
We are hoping for a fix in the Gingerbread ROM...
Also do you have the newest baseband installed when using FR12?
I already experienced this with fr8 and the old RIL so I don't think it's a baseband/RIL mismatch problem. I will see if fr12 and new radio improve things though.
Btw, I can see that phone/data layer takes up as much battery as wifi. Is that a normal ratio on an android phone? Can't remember battery usage on my previous phones.

phone charges painfully slow

I was under the impression the charging capabilities of this phone were insane? My note 4 is charging very slow even with the phone off. Ive toggled the Fast Charge on and off (battery page in settings) and regardless of what i chose its very slow. I think my Note 3 charged faster than this. Is something wrong with my charger or my phone? Should i echange it for another?
Exchange it. With the included charger mine charges in about an hour.

The way fast charge works is with wall adapter and cable that came with phone and screen off. Another way is phone off. Takes a bit over an hour when phone dead
NOTE 4
Looks like I'll exhange it then, cause with the phone off, it took about an hour to go from 25% to 38%. Its strange cause my note 3 was usable while using GPS, and phone connected to car charger, not even a 2.1amp one and it would charge quickly. Note 4, actually went from 38% to 52% in about 3 and a half hours the same way
Mine is the opposite, charges fast and and drains fast. When I unplug it will go from 100% to 95% in 5 minutes with no use and screen off. I tried several battery app with no success to fix the problem.

Fast charge will only work screen off. If u using GPS then phone is awake and u get slow charge
Also make sure fast charge is clicked on.
NOTE 4
Did you take off the plastic stickers from the charger? Mine started fast charging after I did that. I think it was covering part of the connection somewhere.
I hope u connected to ac and not USB check battery in settings make sure it says charging ad and not charging usb
Yes mine says it is charging via AC. I havent removed the plastic from the charger, ill try it. The weird part is, last night i had 5 percent battery. At around 2:30 i turned off the phone and connected to the charger. I wake up around 9:30, a whole 7 hours later, and the phone only charged up to 89%. It takes 7 hours to not even charge full percent? Is that normal? Granted, if i turned off the phone or even had it on, my Note 3 charged within 2 hours or less even from dead. So i should just exhange the phone right?

NOTE 4

[Q] Charging Issues - Is 300-400mA input normal for Z1 stock changer?

For some reason (since lollipop cm12 nightly 20150121, currently on DStrikerz 4.7 stock-based ROM) my phone takes a while to recognised that the charger is plugged in ( an average of 1-2, sometimes not at all, sometimes longer and/or sometimes it randomly stop charging in the middle of charging).
This is what I have done:
I have done a clean flash by going to CM11 (not CM12) back to Dstriker ROM thinking some residual code may have stayed from Lollipop CM12 (cause it had slow charging issues, reported by many), but issue still persists.
I have tried different Power Bricks. I get 700-850mA from iPad charger with 2.4A (2400mA) output with stock cable. I get 200-300mA on a brick with 400mA output.
I have yet to fully verify this but I have had no problems with the other bricks (still need time)
(End of What I have done)
Now my question is that:
Is the lower mA normal when charging?
Do I have issues with my charging port (had charging port issues on previous phone which is Sammy GS2) or is it the brick and/or cable?
How long does it take for your phone battery percentage to go up 1% on average (mine is 1.5 - 5min average) ?
Any other software solutions you can suggest? (Optional)
Can you post a screenshot of the mA of your battery while charging so I can compare? (Optional)
Look at the screenshot at the bottom.

My phone has stock rom, and i used to have the problem of phone immediately not starting to charge...
I found out that the stock cable was loose when connecting, so i started using the cable of my older xperia u, which works fine
Have you tried turning off the phone and then charging?
Because sometimes the kernel gets moody and all that, i had these problems on my xperia u, and i then used to power off and then leave it on charging for some time

That's for the reply I just found the problem. It was the plug. My friend connected it to his GS3 for 1 hour and it only charged 3%. I've tried other charging plugs with stock cable as well for the past night and didn't have any problem. So I might have to replace or fix the plug myself.
test again try to start charge when the battery is at 20% and see if it still 300-400 mah so u may have to get a new cable or to get new charger also maybe the plug
the charging from 90 to 100 is usualy slow comparing from start to 90
test and tell

I checked too, my mobile also had around 400-500mA too, although it is charging and behaving normally

Interesting. I pushed the USB connection on the plug upwards (seen attachment) and it started charging properly at 700-900mA until 90% where it was 300-400mA, compared to the 300-500mA no matter what battery % I had left.
Charging was much quicker.
I remember doing the same on the GS2 charging port and phone charged properly.
I guess its something to do with no reenforcement at the top of the port. Both S2 micro USB port and Z1 USB charger plug port have no reenforcement at top. Think this is a design flaw.

Maybe, but my mobile also get fully charge in about 2 hrs max, and when i once checked this app about current, it was showing around 400-500mA at about 48%, although the mobile didnt take time to charge, maybe at that instance the current was that?

Slow Charging 9.7" Tab S2...

Hey guys,
I haven't used my Galaxy Tab S2 in a while now. When I plugged it in it was at 0%. I used "a" (possibly not original that came with box) OEM 2.0A Samsung Charger + Note 5/Samsung Official Cable to charge my tablet. It has only gone up by 5% in the past 30 minutes.
Also when it was at 0% it said it'd take 7hr 12min to fully charge.
Is this normal when the tablet has not been used in a long time, or am I possibly looking at a bad charger/cable as the charger and cable charge my Note 5 just fine at the normal (non-fast charge) speed where it charges my phone fully in just over 1hr 30 min.
If someone could help me out to resolve this I'd be grateful.
Thanks! :laugh:
Don't think the charger and cable are faulty as they work on your mobile. Generally whenever I charge my Samsung galaxy tab s2 using a different charger it shows a notification if the charger plugged in is slow. If it didn't show this I don't see why it would take so long other than the charger your using has a lower output causing it to take a lot longer than usual to charge.
Every android device I have will sometimes not charge fast enough - it doesn't matter what charger I'm using. If I catch that the charge is slow I just unplug it and replug it a it'll be normal again. I think the "smart charge" goes crazy sometimes.
I had the same problem on the tab s2 8''. It was because the motherboard broke. They fixed it under warranty.
When I had this problem I couldn't attach any external device (usb, playstation controller) through USB. Try if you can
I don't have the original charger anymore to compare on my 9.7. I use anker potable batteries to be free of wall sockets. It isn't 2.0. In battery monitor widget, really good app, shows charge anywhere from 1200-1600mA 20% per hour while in use during charging. 5 hours total. I think with screen off I get 30%. I get 10 hours of screen on time zero loss with it off over night. Using 5.1
It could be the motherboard. I know with laptops charging starts to mess up a few weeks before it no longer works at. The connection between the USB and board weakens over time/use.

Sounds normal. The big Lion batteries in these devices are just weird at time. Running one down to 0 is a good way to kill the battery permanently. Let it charge slowly and then keep it above 20-30% from now on. Should improve over time.
I think its a myth you shouldn't let the battery get low. As long as the battery itself says I'm at zero at the correct voltage then zero is perfectly fine. I'm not an expert here but at 5% battery I'm at 3.6v and will turn off in a few minutes after that. I think batteries are manufactured to safely go down to 3.2 before saying no more. Need to charge.
