I believe I am facing an overheating issues on my N7100 while charging - the battery temp will go up to 38°C or even 39°C if i constantly check my messages and email during the charging period. I done nothing to the CPU nor the frequency and no overclocking app install.
During my normal usage, temp fluctuate between 28°C and 31°C, and that of course depends on the whether and usage activity. Is it normal for N7100 to get to that high temp? My phone will get very hot especially on the top (speaker) part.... be it during charge through the main power plug or power bank.
However, if i leave it there for it to charge. The temp will remain between 34°C and 35°C which i think is hot too. Anyone mind to provide me the correct temp scale for me to follow and take notice of for N7100. Gracias!
Did some testing of my Note 7 using the apps CPU TEMP and CPU-Z and running ANTUTU and found that under load my cpu temps spiked @ 80c, but battery temp was 31c, also tested unit while charging. battery never went over 28c yet the unit jumped up to 62c removed charger and the unit cooled down to 30c very quickly. I thought this odd as one would have expected the battery to heat up on charging not the CPU's
Cpu will heat if you bench it if thats. What you mean
I know that thus why i did the test, but 80c is extremely high, I did the same tests using same apps on my S7 Edge and it never went over 33c.. my posting was more about the CPUS's heating up and NOT the battery
Mine was at 82c when i ran benchmarks
Mine Battery temp always stays 29c to 34c (while charging).
CPU temp < 42c
I've seen mine get as hot as 90/79ºc for CPU/battery temps. Its a safe to say that I plug my phone in the corner of my room now. Not even kidding.
(Using stock charger btw)
My cpu temp was 52c max when testing and battery was 34c
Sent from my SM-N930F using XDA-Developers mobile app
3 days ago I have the Nokia 6.1
I realized that when using the charger the mobile temperature increases to 47 degrees, my solution was to use a normal usb charger instead of the original, but i read on the internet that the normal temperature of the li-po battery is 0c - 40c
and my phone in normal use have 34c - 39c with/without normal usb charger.
i made tests playing and the CPU reached temperatures of up to 69c and the battery does not exceed 39c
Then is it dangerous? i'm worried about the temperature of the battery, especially because the ambient temperature where I live is 30c, and my old moto e (2014) never had more than 30c in the battery.
Something wrong with my Nokia? How can i lower the battery temperature?
Sorry for the mistakes, i rarely make a post
Hi. I have the Indian version of the device, which is Mi 11x 6|128GB variant. I noticed while charging, Accubattery shows battery temps of 45 46 degrees Celsius (113 Fahrenheit). I find that not normal for a new phone. I'm coming from a Poco F1 which had a SD845, so here are my doubts:
1. Does all flagship class SoCs heat up that much during charging? But my Poco F1 didn't.
2. Is there something wrong in my unit or is it faulty cooling implementation on the entire Redmi K40 lineup?
3. Can I expect this issue to become a little less in the future after some updates to alter SoC clock speed or something?
Thanks for reading.
Thats normal if you use the included 33W charger, the battery naturally heats up while charging, the fatest you charge the battery the more heat it produces. is always recommended to not heavily use the phone while in charge. just for the sake of doubt you can try use a 5W charger and see if it heats up while charging slowly, (it should be hot just a little).
What's the ambient temperature?
Is it fast charging? Which typically produces a,fair amount of waste heat.
If it's start temperature is 99F it will climb into the triple digits.
You want the battery to be above at least 72°F at charge start to prevent the possibility of Li plating.
While it may be normal for this phone, you are beating the battery. It's been reported that high temperatures during fast charging can promote Li plating.
Cool it once it reaches 99F, with a fan and/or a damp microfiber cloth.
On my Samsung it will stop charging if it goes above about 102F. Samsung tends to be conservative with their charging parameters.
Not a bad thing as it lengthens battery lifespan and reduces the chances of a thermal runaway event.

I'll try this with my Poco F1 charger and let you know what I find

Ambient here is 86 Fahrenheit and above. While charging the phone, I don't even use it. I just put it face down on the screen so that the heat dissipation is faster from the back surface. But still it reaches those temperatures and is making me doubt the QC process of Xiaomi in this case.

It may dissipates more heat through the display.
Never use a phone while charging as it skews the charge cycle parameters.
Simply cool as I described or don't use fast charging.
You can also use partial charge cycles like 40-60%. That's also part of the range the battery pulls high current and heats up.
If I see my battery temp climb above 100F I will stop the charge and hit it up a little latter.
For my Samsung the optimum battery temp range for fast charging is 85-100F. Outside of that range fast charging may not always engage or stay engaged. However in that ambient temperature range I need to some form of cooling when fast charging if I want to maintain a temperature under 100F.
Always keep an eye open for case swelling which indicates a battery failure. Replace it immediately if that happens.
It becomes more likely as the battery ages or if exposed to temperature/current extremes. I just replaced a failed battery at the 1.5 year mark on my Note 10+.
Fun, isn't it
I just checked the charging with my Poco F1 charger which is 18W. The portion just below the camera module heats up the most. And the temperature between charging with the 33W charger and 18W poco charger are same. At least that's what Accubattery says. I'm replacing this device for sure, let's see how the replacement device works out.

If the temperature is the same than it's not fast charging. Fast charging generates much more heat however even while it's enable the charge rates vary due to temperature, charge state and battery condition.
For instance between 80-100% the charge rates will be about the same. This may start as low as at 70% or even lower if the charging parameters aren't optimum.
The easiest way to tell is with an app like Accubattery. Put it on the charge page then use the power button to turn off the screen. Start charging. You have about a second if you turn the screen on to see the screen off charging milliamp figure. The charging log also tells what was happening but not when it happened in the charging cycle.
At maximum rate mine tops out at around 5200 ma using a 25 w brick. It varies between 1700- 5200 until it starts ramping down as the cell nears a full charge.
Nearing 90-100% it may be 800 ma or lower.

But 45 degrees Celsius is not normal for a new device dont you think? I mean if it was 65W charging I'd say maybe it can get a little toasty but for 33W I'm sceptical.

If that's the battery temp, it's high. The CPU can easily run beyond that though.
If the whole phone feels hot you got issues.

It's generally the back portion of the phone specially the part below the camera module. I'm getting the device replaced tomorrow. Let's see what happens
People keep saying that their chargers are not working. I noticed via AccuBattery that once my phone exceeds 100-104 F, that the phone stops charging until the phone cools down. I don't think this is a power brick/cable issue, I think this is a thermal management issue.
It's done to try and protect the battery from unnecessary stress and possible damage.
Optimum Li charging temp range is 82-99F
A start temp of 85F is better.
Never attempt to charge below 40F
Avoid starting charge below 72F
Fast charging will likely not engage if temperature is too low (around 71-50F or less).
Charging will disengage if the battery gets too hot about >103F.
Fast charging may disengage at 100F and will start ramping down around 80% and ramp down even more as it approaches 100%
