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

So I got this phone 2 days ago and I love it except for the battery.Anyways,the battery temp while charging is 34c is this normal?(37c while writing this in chrome)And I noticed that battery drains pretty quickly while gaming(like clash of clans)and hot from the back-top.So is this normal?n
Yes, this is normal. Having the screen on while charging will make it even warmer. Be aware that the phone charges more slowly when the battery rises above roughly 90F/32C, so keeping the phone cool will help with charging speed. Mine will drop from the max of 1600mA with the stock charger, to about 300mA, as the temperature reaches the low-90's F.
Thanks for the reply!
Yeah I noticed that.When ive put the phone in an air conditioned room,battery tempreture decrased to 31.5c and the voltage increased to 4300 mV.But I did a research and found that li ion max voltage is 4.2v anything up is dangerous unless the battery got some sort of overvoltage protection.So should I be worried?
No. Mine charges to 4.4V. I'm comfortable that this is a safe value for the battery.
If LG had it dangerously overcharging every single battery, that would be incredibly irresponsible. I'm sure they picked a safe voltage.
Guys - what app/s are you using to measure. I use Ampere but is there any better?
Thanks.
Just go to the hidden menu by dialing *#*#4636#*#*
That doesn't show the charging Ma?
So I've noticed my 3xl is crazily boosting power to the phone when charging. I've seen it go all the way charging at 35watts until it reaches 10% then it slows down at 22-25watts until it kind of reaches 25-30% and then it goes to at 15-18watts until it reaches 100% which is lame.
I've read the charger can deliver 65watts and I've used it to charge a laptop which is incredibly fast and it charges my Xiaomi mi pad 4 plus at 22watts.
Why can't Google lock it at somewhere between 25-35watts? How's your charging? Is there any mod/way to charge it more rapidly?
The reason high speed charging cannot be maintained is due to battery physics (or... chemics). When charging battery with high power, you actually stress the battery a lot which will reduce the "total life" of battery. This reduce is (partly) due to the high temperature associated with high current (the battery voltage is pretty fixed around 3.8~4.2V, thus high power=high current) and this high temperature put a lot of stress on battery materials cause shortening of total life.
Also, if keep high power charging too long, the battery will have risk of explosion (for various reasons... High temperature is only one of the them) for example, one of the temporary solution Samsung implemented for Note 7 on fire issue is limiting the charge power, to reduce to risk of catching fire. Big company with a lot at stake like Google usually will not trade safety for anything (there are exceptions.) This is why high speed charging is limited. (sometimes hardware limited for safety reason).

65 watts? Not the charger that comes with the phone. Read the output (tiny) label on the stock charger). So maybe you are using a different, badass? USB-C PD charger that supports higher charging rates, but the PD protocols our phones accept are theoretically 18 watts max: [email protected]=18w, [email protected]=15w and legacy [email protected]=10w. You will not see higher than that, and it is regulated by the phone irrespective of the charger you have. The phone's charging amperage curve starts high at very low battery capacity and then tapers off pretty quickly. If your display says "charging rapidly" then you are getting the max rate you can achieve. Hope this helps.
Does fast charging as opposed to normal charging (FC turned off in device care) as our standard means of charging our devices affect battery lifespan in the long run?
All things being equal, I don't think that it does

Well, thanks. But it's the noticeable heat generated from fast charging that gives me some concerns whereas in normal charging, the heat isn't that much.
Well, no such differences with chargers I use but if there was I would be probably use normal charging
No. Charging doesn't harm your phone

Its a known fact that high temperatures are bad for lithium ion batteries, fast charging generates more heat than std charging, if there are no adverse effects by fast charging, then it would not be an option, it would be the standard

Fast charging is fine as long as you control the heat; brief 10-30% partial charges generate a modest temp increase. LIs are designed for fast charging.
If your ambient room temp is high simply wrap a damp rag around the phone while charging to cool it.
Monitor bat temp and keep it belong 95 F.
-Avoid full or near full charging-
60-70% is a good range; > 62% is ideal for longevity.
Avoid discharging below about 20%; low voltage isn't as efficiently converted and there's a knee in LI's power curve near that mark; battery % drops more rapidly from 20-6%.
Deep cycle recharges stress the LI much more than short 10 or 20% bursts.
LI's love frequent, short charge cycles in the 40-60% range.
Keep battery >100 F when using, charging or storing!
Avoid using the phone whilst charging; it screws up the charge cycle curve and greatly slows charging!
Same-same if battery temp exceeds 100 F!
25 w brick yields about 2%@ minute charge.
A few weeks ago I bought this equipment, and since I have it when I charge it with a fast charge 3.0 charger it heats me from 41 to 43 degrees, it only lowers the temperature when it is almost complete by 95%

if you charge when the battery is above 20%, "optimize charging" is activated and the temperature will be very low. If the battery level is below 20%, fast charging is activated and the temperature will rise
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
