My poco f3 reaches 38/ 38.5ºc while only doing social media or some browsing, and has a bit fast battery drain. Any help? Now it's like in the photo
With regards to battery temperature:
It also depends on the back surface of phone. For example metal surface get more heat while plastic surface get less. And it also depends on the surrounding atmosphere temperature.
Generally 35°-38° Celsius is normal for device.
Above 40°C indicate to put phone ideal.
Above 45°C indicate to switch off phone for some time.

I'm running Liquid Smooth 3.2 with Imoseyon Lean 6.2.1 kernel. I also tried to activate the speed tweaks included (?) but it didn't work so I downloaded speed tweaks 7.1 from Imoseyon's website and flashed it.
This is my problem.. I understand that with this kernel USB fast charging works unless the battery temp gets too high, then it shuts off and I assume goes back to standard charging. I've been using the kernel for about six hours and the battery temp has been in the low to mid thirties mostly, so that's great.. But my voltage has gotten up slightly over 4200 a couple of times and that has driven the battery temp up, but not much. I use a battery monitor widget that sounds an alarm if the temp or voltage get outside of my defined ranges.
What I would like to know whether there is a way to keep the voltage in a safer range when the phone is fast charging? I think if the fast charge could be stopped when the voltage is above 4200 or below 3000 like it is when the battery temp gets too high would be a great feature, and it would ease my mind that the voltage won't spike to 4300 or 4400 and blow up while I'm sleeping at night (if I happen to not hear battery monitor alarm).
If that's just the way it is with the voltage spikes, does anyone maybe know of a kernel/rom combo that safely allows fast charging by keeping the battery temp and voltage in recommended ranges or by shutting fast charge off if the temp/voltage suddenly spike while on the charger?
Thanks for reading/considering my question.
I'm not 100% sure but isn't the reason fast changing works is because it bumps up he voltage. Wouldn't lowering it make it not charge as fast.

Not sure
I looked at my battery history and I think you're right. The voltage has spiked quickly and then steadily climbed past 4200, but the charge in that time frame is like 60+ percent so it's worth it I guess. Figure I'm hurting the battery, but for now it's worth it. I I may get an iphone 5 if the features are right.
I guess I'll just have to find a toggle so I can leave it on the charger at night and not have to worry about it catching fire. Just out of curiosity, does anyone know about how long a lithium battery can charge above 4200 or below 3000 before it blows up?
Also, this is my first phone with a 4.3 inch screen.. Do all big display phones suffer from terrible battery life? I keep my brightness down to about 20% indoors, but I generally keep 4g on because 3g tends to drop the signal and I play Pokerist a lot at work. Don't like getting kicked off and having to sign back in when I'm all in in a hand. I guess it also could be that the game is taxing the processor and in combination with 4g wrecking my battery life.. Mainly though, and on a custom rom without a fast usb charging feature, I couldn't play and charge at the same time, the phone would just barely stay at the percentage it was at. My last question is, does anyone know of a phone with a large display and 4g that doesn't drain the battery as quickly as Thunderbolt, or that at least charges fairly fast while using phone without having to flash a fast usb charging kernel?
edit: I can't find an app or widget that will allow me to toggle between normal charging and fast usb charging.. Anyone know of one for Thunderbolt?
Most of the new 4G phones with the 4.3 inch screen suffer from batter drain. The razr maxx is the best stock phone for battery right now but the phones just aren't built well. I think the newer phones are getting better so I would wait a little while longer and see what is coming out soon. The battery issue won't be a problem forever and neither will the crappy data drops.

The spike in voltage and temperature is a NORMAL behavior of this type of battery and the charging technology it uses. As a Li-on battery discharges, it's voltage drops very little for it's corresponding level of charge (Very useful in small electronics that require excellent power consistency.). As the battery nears fully discharged, the voltage begins to drop sharply as does the resistance of the battery. Shortly after that, the internal temperature rises. You are now damaging your battery to further discharge it. You're phone won't let you do this. Likewise, it won't allow you to overcharge it. A Li-on battery is determined to be fully charged when the voltage output begins to rise sharply over the nominal charge rate. The internal resistance of the battery will rise sharply as well. The you'll notice temperature rise. Depending upon other conditions, a significant rise in cell temperature doesn't necessarily indicate a charged battery. If the resistance and voltage are consistent, the battery isn't fully charged but rather exhibiting the normal rise in temperature as resistance rises. You'd be pretty shocked how hot it really has to get before the phone will simply shut itself off and refuse to power up for half an hour or more to avoid actually damaging the battery due to thermal stress. Think hot, dark stone sitting in the hot sun all day long. And that cut-off, as far as I know, is below what the battery is actually rated for.
You're HTC device uses neither voltage, resistance, nor temperature independently to determine a charged or discharged state. That is calculated through compiled statistics based upon load, voltage output, resistance, and temperature. Li-on is a very well understood technology. The ONLY way to obtain the life and performance from these batteries that they do is to have fairly advanced charging and monitoring technology. It's really pretty hard to destroy a phone or it's battery strictly through heat generated by charging (assuming all parts meet spec.). In fact, it's hard to even if the phone is sitting on a heating vent or under the hot sunlight.
Unless you're device is some brutally overclocked, customized to the gills monster of a device, narrowly switching transistors at ridiculous speeds with precious few electrons to spare, you're pretty hard pressed to damage your battery or your phone. The stuff that manages the battery is beyond what kernels and ROMs do. You can definitely do some meaningful damage to a battery messing with charge characteristics, however catastrophic failure is practically impossible.
Just a little process of elimination on the overheating issues.
To be clear: I don't have the issue of continuous overheating when nothing seems active.
I do have a problem with it overheating when playing games or streaming.
Also the overheating and drain is so bad that the battery will drain even while plugged in during this time.
so, do you have the same problem?
To keep the results consistent please test with this scenario:
Play Asphalt 7 until it heats up noticeably. Then plug it in and note your charge level. Now play some more and see if your battery drains.
I think the overheating and faster battery drain is normal.
For example if the CPU and GPU need 10W to render such intensive game at 24fps and your charger can supply only 5W (5 Volts * 1 Amps) then you have battery drain, not charge.
Try charging your phone with charger that can supply 2A (usually phone chargers are 1A), then you might actually charge your phone while playing this lovely game.
The whole point of this poll is to determine what is"normal" so we don't have to come up with theories.
BTW: I have never seen this happen on an iPhone or Android as manufacturers usually engineer their components to accommodate.
I haven't played Asphalt, but some other games, and yes, the phone overheated, there was no battery drain, BUT the battery was charging significantly slower.
Using 3rd party navigation apps like "Navigation 3D" and "GPS Voice Navigation" overheat a lot the phone and the battery drains in a couple of hours from full charge.
Also with my 500mAh car charger the phone drains with these apps.
Overheating for me is when the phone gets so hot that it will shutdown to prevent damage.. or is damaged...
Did your phone gets hot or is it really overheating???
Phones can get really hot when you combine some of this things:
-Charge
-use wifi
-use heavy apps (navigation) or gaming
-stream or watch videos
-have your screen on full brightness
-use it in heavy direct sunlight (like in the car)
the more things you combine simultaneously the hotter your phone will get...

According to the poll so far: 40% of phones don't overheat and 20% don't have the voltage drain.
If 100% of phones behaved the the same then it would be easy to accept that this is normal behavior.
But I'll keep sending mine back until I get one that works.
the term overheating implies that the device stop functioning
running hot would be a less confusing and more appropriate terms. All electronic devices run hot under prolonged load, laptops, tablets, ipods, it's par for the course.
Obviously I didn't mean that malfunctioning is normal. I agree "Running hot" is more appropriate term..

What I'm trying to do is provide a baseline acceptable level so we know what overheating is.
I already know that something is wrong when the provided charger cannot charge the phone and the and the heat level is uncomfortable.
Overheating is: anything that is beyond the designed run temperature threshold -which we don't know but can discern through collaboration.
Well through logical deduction on could come to the following conclusion. Phone does not charge with provided charger, phone get uncomfortably warm, there is only one thing in the phone that can generate that heat and that is the battery. It is a Lithium Polymer battery and they are notorious in any device for having workmanship issues. Since it won't charge that points to the battery even more. I would take it in and have them change the battery since it is a major undertaking for a regular user. Or just exchange the device. Just tell them you afraid it is going to cause a fire.
My g5 gets pretty hot(40-45°C/104-113° F) while fast charging with QC 3.0 charger,is this normal or am I just being paranoid?
I think if android gets to hot it automatically shuts down at 150 f I think? 70-90 seems like the normal temp maybe more or less depending on what your doing. I would imagine it be on the higher side while charging. What app you use to monitor temp of phone while charging? I will test mine and report back results.

That sounds normal if you have the display on or have a demandingly busy/weak WiFi/LTE signal while charging.
Also note you will get throttled charging speed the warmer it gets - the system has several monitors on-board to protect from getting too hot. You can see what the system settings for temperatures are in root > system > etc > thermal-engine-8996.conf.
I attached a screenshot of some relevant settings from that file. The thresholds are degrees Celsius; you only get optimum charging speed with display off and temperatures below 42 °C. (Always-On Display setting doesn't seem to affect the "LCD-On-Monitor" for this purpose.) Temperatures 45°C and below are equivalent to 1 amp charging - slower but still decent. Any higher and significantly slow throttling occurs.
As a side note, you can physically verify this kind of info with an in-line "USB power monitor" device. It sits between your charger and cable and displays the volts and amps for you. Usually costs $10-$20 USD. Make sure it supports at least 9 volts and 4 amps to monitor QC 3.0. (Mine has a range of 3-20V and 0-4A.) Handy for figuring out if your charger or cables may be faulty and verifying charge rates.

you can improve the temperatures if you tear down the phone and apply mx4 in the cpu and ram, 10/15c of improvement at least. the g5 have ****y thermal pad, and cooling sistem.

Sorry for late reply,I am using accu battery which shows complete statistics.Anyway can you please tell me whether it will cause damage or not to my phone? Touching the phone while it's charging and screened off feels really hot.

My screen is off and its averagely arround 42-43°C but it's still charging at maximum speed i.e around 2900 mA and could you please tell me that all those temperature monitors which show live temperature are showing CPU or battery temperature? Because if it's battery it's written that the temperature shouldn't go above 40 and since it's going,wouldn't that be dangerous?

"Li ion batteries offer reasonably good charging performance at cooler temperatures and allow fast-charging in a temperature bandwidth of 5 to 45°C (41 to 113°F)." The battery can charge between 0 and 5°C and above 45°C but it will be reduced speed.
The discharge temperature range is "–20°C to 60°C (–4°F to 140°F)"

Anecdotally I've had my HTC Rezound battery abused many times with charging (slowly) at or above 45°C. One night I even had it around 65°C when I fell asleep with it on a faulty charger *and* thermal safety on the OS disabled. After many cycles and abuses it had a very slight bulge and maybe 50% original capacity. Needless to say I bought a new battery, but it shows the limits in a proper li-ion are well above the charging/discharging temperatures.
You should only worry about performance degradation above 45°C and not approaching anything "dangerous" until perhaps north of 60°C.
I'm charging my G5 right now and using AccuBattery app as well, first couple of minutes I'm at 34% and 40°C with screen off which is in line with your results. I'd call it warm but not alarmingly hot. I'll test more charges on G5 by tomorrow.
As is known, in android devices, there is no charging process up to the physical capacity of the battery in the battery charging process. The Android system charges 70-80% of our battery, depending on the physical capacity. I'm looking for an application or Magisk module that can change these limits. To remove the limit set by the system by default and use the physical battery capacity of the device. I am aware that this process will shorten the battery life of my device.

Better go by voltage not %.
Better read the white papers for that particular cell before you begin. I also suggest you autopsy an old "bag" Li. You'll be amazed how flimsy they are and with only a goofy plastic bag to seal it.
Overcharging an Li can easily turn into a thermal runaway "event".
The charge curve is written in blood especially Samsung's
Top charging can also cause Li plating which can degrade an Li rapidly and potentially cause a membrane breach ie an event.
The higher the charge, the more memorable the event will be...
just recently bought an otter box magsafe wireless charge because have one of the magsafe rings on my case. When charging WITHOUT THE CASE on and having the phone just sitting on the charger, it showed in Ampere that my phone's battery was reaching 105 when charging at 7.5W in just a few minutes (it started out at 80). I pulled the phone off at the point since that seemed way to hot. I also tried to charge with the case on with the same issue, only the wireless charger got way hotter due to the magnet on the back. Is it normal for the phone to get that hot when charging at those rates wirelessly? For reference this was the charger had got since it was rated for Ql EPP: https://www.otterbox.com/en-us/magsafe-charging-pad-for-magsafe/charging-pad-magsafe.html
What's the ambient temperature in the room?
105F is charge disable range; keep it no higher than 103F, under 100F is better.
Some heat is needed for charging to work as intended as it's an electrochemical reaction.
Li charging is actually a endothermic reaction but internal battery resistance negates this phenomenon.
Optimum battery start charge temp in 82F.
Use a damp microfiber cloth and/or fan to cool if needed as it approaches 99F. High temperatures and past 85% charges burn up Li batteries fast...

Thanks for the information, my room temp is around 75 F. I was thinking about returning the wireless charger as it was doing that in a room that was around 70 aswell.

That maybe normal for that device but that's not a reasonable trade off. I can fast charge and easily stay in 80-90's at 75F ambient throughout the charge cycle.
Go for cable charging. C ports generally have an insanely high cycle/long service life. Not like the older micro jacks. The C ports exceed the Apple Lightspeed jack lifespan too.
A minimal battery start charge temp of 72F is recommended to avoid the possibility of Li plating which will permanently degrade the battery if it occurs.
I'd say that 105F (40c) is on the high side of normal for wireless charging. Wireless charging tends to generate more heat than charging through a cable does because of the heat generated by the inductive coils. If you have the phone in a case that makes it even worse, as it reduces the efficiency of the wireless link and holds in heat. IMHO, wirless charging degrades the battery faster than proper wired charging.
