Obviously not this particular one, but something to split the micro usb so we can charge the phone while using the VR, which is my only real issue with it, aside from phone warming up pretty bad.
It probably would be easier to modify headset itself and build charging port into headset or some kind flat cable with microusb on one end and another end could fit betwen battery and phone contacts or maybe someone discovered which are charging pins under back cover (used by charging back)

Agreed, really wish samsung would have added charging, the only real downfall of the VR.
How about the QI mod I've seen people talk about? Seems like a good idea, basically just stick the pad in the front of the visor, aside from health risks from doing this lol, I'm worried that the VR will drain the battery faster than the QI charger will charge, but if anyone has any experience with it, I'm all ears!
Hopefully, the next version of the VR will allow charging.
They need to figure out the overheating before dealing with the charging if its hot already, imagine how much worse it would be while charging! At least we can quick charge!

There were concerns about people strangling themselves while charging the phone with a cable. And the additional heat is probably also a factor.

Well the samsung demo booth had a battery with a cord and a special cover with a hole in it. The cord was mainly for security (the battery screamed when removed from the phone, which the guy setting it up had to do to reboot it occasionally), but I'm pretty sure it also supplied power, since it was the only one in the booth and the thing was running all day long. We might be able to make our own usb-powered battery blank. Not only can we then do external power, but it should also help remove some heat. If there's enough room you could even add a peltier
I know its more money but invest in the official battery kit. If you're serious about using VR it's really the smartest option especially if you're showing off at a party.
I was watching this live YouTube stream and the guy was killing me with his low battery issues. It takes a minute to swap for hours of entertainment. And your depleted battery is charging as well. I bought mine at bestbuy because Samsung is always out of stock.
Glad Tidings!
It is my understanding that, with standard 5 volt chargers, in general a high voltage charger is preferable because the device takes only what it needs. I am curious what the thoughts are concerning the Qualcomm 2. 0 technology, and if the consensus is that the same holds true for those devices.
The reason for my question, is that I purchased a Qualcomm 2.0 charger that puts out 25 percent more power across the board than the stock droid turbo charger. Should I be worried, or just let her rip on my new Droid turbo?
The stock charger has the 2.0 technology as well. Which did you purchase that puts out 25% more?
From Motorola's website:
Our fastest charger ever — incorporates Qualcomm® Quick Charge™ 2.0*

No worries, the phone is measuring battery temperature and other variables continuously while on charge and it will adjust the charge accordingly, when done it will stop charging altogether. This is also why if the battery is completely dead it wont quick charge until it picks up a little battery, quick charge has to be enabled by the phone and the phone cant enable it when it is dead. Just an fyi...
Thanks krabman!
Great explanation, leaves me even more impressed with this phone! I have been just a bit concerned about heat, as the temperature gets up to 111 or so. Good to know I needn't be too worried.
C, the charger I bought is a Tenergy. It puts out 18 watts at the two Qualcomm 2.0 configurations, and even cranks out 10 watts at the standard 5 volts. It's actually a pretty cool charger, the indicator light glows blue for standard charge, but changes to green when it is charging a Q 2 device.
Merry Christmas, Happy Holidays everyone!
I have gotten the phone yesterday to 135F and I could be baking cookies on it ahahaha. Reason why it was so hot was because I was downloading movies on my phone and charging with turbo charger. But at 135F I got a warning saying temperature above normal. Once I disconnected the phone it went to 132 F and got new notification saying temp back to normal. So my guess is that the battery can take some serious heat.
My phone gets hotter than usual when I'm using a Qi wireless charger.
woke up today and my phone was at 48°C. It's hot as hell here, tho. 31°C right now...

Yeah, man! I wasnt expecting that high temps. My phone was charging, but during the night I turn everything off, so it doesn't wake me up.
I really don't wanna try doing high usage tasks while charging...
I've had a couple phones with a version of the quick charge feature and they all got hot while charging, the Find 7 can get uncomfortable to hold if you are charging while surfing as an example. With any of them taking charge at idle they got warm but I wouldn't say hot. I am curious about having a high temp on a wireless charger though, I wouldn't have expected it. The N5 was my last phone capable of wireless charge and I don't recall it getting anything more than slightly warm. I'm not sure if it makes any difference but I had the Qi charger google sold, it was fairly slow charging.
same here
I had a previous model of this unit which was at the old "slow" charge rate and was so pleased to get the new and improved version. They even fixed the few issues I had with the older version. This model has the charging cable in back instead of sticking out the side, the LED indication light is much dimmer, although larger, which makes it easy to see where to place the phone in a dark room and not act like a flashlight while trying to sleep.
The display angle is acceptable, it works well through a case, although I haven't tried a Defender case yet and the fit is more secure than even the Samsung charger..
The unit uses a microUSB connector and a 2.1A adapter, not included.

To anyone thinking of wireless charging for our device - I advise against it. Not only will it charge rally slowly compared to the standard charger - it'll generate a tonne of heat and kill your battery rather quick.
I use a cheap chinese QI pad and it doesn't get hot but I discovered you need to switch off fast charge (under battery) and it works fine. Granted it charges at a rate of 20% in 30 mins but for overnight it fine....mine doesn't seem to get hot or even warm.

I have used wireless charging since the Nexus 4 and never had any trouble with reduced battery life. Nexus 4, Galaxy S4, Note 3, Note 4, and Note 5. Except for the S4 which I returned to switch to a Note 3, the battery life is about 20 to 24 months with little or no reduction in usability. When I get a new phone I hand the old one down to my wife and other family members, and I have ordered the new batteries when needed.
Hi everyone, I'm new here with my Note 9 coming from a Galaxy S5. I have 2 questions.
I want to know firstly what (wired) charging do the majority of Galaxy Note 9 owners employ? Standard or fast charging? I am very weary of fast charging because of increased battery degradation.
My second question is this. I am assuming that fast charging increases battery degradation because of increased heat from the higher voltages. And yes I know that it is adaptive and gradually tapers off. I have run an experiment. I have installed a couple of battery temperature apps and charged through standard charging. Then I have put the phone on a solid piece of steel plate and charged through fast charging. The temperatures of the battery are identical. I have checked this a number of times. The steel plate even at room temperature is quite cold.
So does this mean that if I fast charge with the phone on a cold steel plate and the temperature is no higher than standard charging resting on a usual surface, that fast charging in this case causes no additional battery degradation?
Thanks.
Fast charging, most of the time
Fast wireless charging all the time. Even when it's in my car dock it wirelessly charges in that can be for 3-4 hours a day on and off depending on journey. Screw battery degradation I'll use the upgrade programme to upgrade next year.
Slow charging. I have the same concern as you hence I off the fast charging function. No diff to me since I charge my phone only at night when I am about to sleep. Do not require charging to be fast.

If you plan on keeping your Note 9 as long as you did your S5 then slow charge with wire and also try your best to charge from 40 -80%.

Samsung is claiming 95% battery charge capacity after 2 years (80% is normal). So there is little reason to hold charging to 40 -80% for the normal lifetime of a phone. And also LION batteries are never allowed to charge or discharge completely - it's hazardous. So Samsung is already limiting how much power the phone can draw or charge the battery. (So do electric car manufacturers)

A quote is worthless without a source, where did you hear Samsung state the phone would have 95% battery charge capacity after 2 years? Also I'm not sure you understand Li-ion batteries, they are allowed to be fully charged but not completely discharged, this is included in the mAh ratings. Also electric car manufacturers do infact recommend something similar to 40 - 80% charging, for example, Tesla by default do not charge 100%. Even Elon Musk recommends 30 - 80% charging: https://twitter.com/elonmusk/status/448466037441179649
I use slow charging. I believe it is quite fast even with slow charging.
If there is an option to choose whether you want fast and slow charging, note that fast one has some downsides.

Although I don't blindly trust what manufacturers claim, I did however test my wife's note 8 and used accubattery pro on her device from new. Unlike me, she would always topup her phone and also fast wireless charge. After a year prior to her trading her note 8 in for a note 9 I checked the health tab, I know it's not accurate however as a ballpark is stated her battery health was at 97% which isn't pretty bad for 12 months of usage. My note 8 was at 99% using the 40-80 rule approx 90 % of the time. If one was going to keep their device longer than two years I'd still recommend using the 40-80 method to prolong battery life. However most Inc myself upgrade yearly so it's all moot. I just do it (80-40) out of habit.

Hlo guys, Hope you all are doing well.
I bought an S21 Ultra (Exynos) yesterday and it seems to be running hot even during normal usage. It heats up while I charge it (with a 33W Xiaomi charger) and it heats up even more (goes upto 43°C) while I am on a video call. I'm a little bit worried. Is this a faulty unit or just a software issue? Please help me out guys.

It will do that for a few days. I had the same experience on the first 2-3 days. But the heating issue went away after that. It will still heat up occasionally (just like any other computer) and especially when you do anything involving the camera. All the new apps are constantly writing info, building cache, etc - this should ease off once the initial intense activity has completed. Some heating is bound to happen when charging too.
The only things I would recommend changing for now are: If you don't use 5G or have poor coverage in your area, turn off 5G scanning from Connections setting. This seemed to help me with battery as well as heating. And FHD+ instead of WQHD+ resolution (at least till the heating issue is gone, and then you can play around with settings and see what you like)
My advice would be to just wait for a few days before doing anything drastic or trying to modify stock firmware. If not better by the end of the week, you can explore other options. The phone is just one day old. Just give the software some time to settle.
unfortunately thats just the way it is
am having the EXACT same issues and i had the phone since Feb so - not something that will go away unless Samsung fixes it

I haven't used the Mi charger. Tried with an old warp charger from OnePlus just for kicks and it doesnt super-fast charge the S21U. But that's becasue the propreitary fast charging standards used by different manufacturers are often incompatible.
After some research, I've found that the S21 ultra will not draw any more than 25 Watts of power (even if you use the Samsung original 45W charger). And even that 25W will work with only with a PPS (Programmable Power Supply) charger (USB C to C PPS) - like the 25W Official Samsung charger. There are a few 3rd party maufacturers that make PPS chargers, but I haven't used any of them. I just went ahead and bought the Samsung one, as there was a good discount on it.
Any other charger you use will only work as a slow charger, or a fast charger (15W max) at best if it supports Qualcomm Quick Charge (QC3) standard. For 25W Super-fast charging (it's anything but super-fast, but that's what Samsung insists on calling it) you need a PPS charger, and I would recommend going with the original 25W Samsung charger.

You're most welcome.
You can be unfortunate with any SOC in terms of die quality. Some people are simply SOL and end up with crap silicon which results in bad thermals and, if you're rooted, a restricted ability in overclocking or undervolting.
What people can't do is have a crap experience with the thermals on their S21 Ultra (or any other device) and talk as if it applies to every other device of the same model, as in post #3. It doesn't work that way.
one thing i did yesterday (btw may update did not fix the heating issue) was to disable the 5g - keeping in mind i live in an area where there is excellent 5g coverage)
as soon as i turned 5g off - the heating was gone, the battery life increased and the phone felt smoother
now this was also an issue last year on s20 - seems this year is the same
something about the 5g that makes the phone get really hot
try it and see if that works

Heating problem while charging is fixed after I started using the original Samsung charger. But I'm still experiencing problems with video calls A 20 minute video call (through Microsoft Kaizala) increases the temperature to 45°C I'm not sure what's the problem. I have turned off 5G as well.

As I'm still experiencing problems with temperature going up in video calls, is there anyway to log the cpu usage and thermals? Maybe that would help in finding out the culprit. The battery life is not that great either. I can't figure out how much SOT I'm getting since the battery page still shows "Learning usage patterns".
i think the heat during video calls is another issue - that is triggered by the actual video processing - i think you will notice if you turn the camera on for shooting a video (not live video calls) you will notice instant heating - i think that is also what is causing this - both frontal and rear cameras have huge sensors and the phone must do a lot of work to compress the live videos + data connection/wifi used during the video
i dont know the culprit but is defo related to the same issue why when taking loads of photo or long vids the phone get super hot
i mean i turn off my video during a call and the heating goes down pretty fast
all in all - it seems the same issues that plagues s20 exynos are still present in the s21 exynos - so not sure what improvements they made cz honestly is as bad as last year!!!
Hey guys, i live in Kuwait and now temps are reaching 45-50°.
I don't expect the device to cool itself and i try as much to avoid using it outdoors or in my car (i have a ****ty AC)
Otherwise while at home and gaming it never exceed 40° ever.
If you dig deep into when you are using and where you will notice.
5g also drain and push temps up waaay to much.
Volte is also a factor.
Btw these are in all phones not only the s21u.
Don't be fooled guys and don't hate the ohone, it's a phone with soo many things and features running simultaneously, it has no fans and no cooling except for the paste lol.
That's my way of looking at it, i might be wrong.
Btw my sister's iPhone 12promax does the same and reach hot temps when used out and camera together.

That learning usage patterns will take a few days before it starts showing data.
For thermal logging and control you can use the Samsung Labs module called Thermal Guardian. If labs app is not available in your country, download finelock from play store and get it from there. Search for appx video on thermal Guardian on YouTube for installation details
Guys 40+ something temps are nothing. Just put on a cover, relax, and enjoy the warm beast your phone is.
There is a direct relationship between the amount of power used by a processor and its clock frequency. The higher the performance, the higher the power consumption and heat generated.
Samsung is teaming up with AMD on an improved SoC which is reported to make it's debut on the S22. Hopefully this will eliminate the ongoing defencies with the Exynos SoC.
Redirect Notice
Not only have some of Samsung's major stock holders pressured Samsung to resolve the Exynos debacle, there's even an online petition with over 50,000 signatures requesting Samsung stop using the Exynos Chipsets in it's flagship devices.
Sign the Petition
Stop selling us inferior Exynos phones!

The only other Non-Samsung Smartphone which uses the Exynos Chip is Vivo. All others besides Huawei and a couple of Chinese Brands use Snapdragon which is pretty good indicator for the lack of confidence in Exynos SoC's
This heath issue has to do with my S21 ultra's reboot thing? Once a day...I noticed that,if I install some app outside google playstore(such as vanced etc), my phone will reboot by yourself once a day....

Look in settings to see if your phone is set to reboot once a day. If it's not, then you have a hardware problem.
