I can feel very hot the phone while is charging but i know at some level is normal for the quick charging, but i will like to know what parameters are normal or acceptable?
I try with a different charger (Xiaomi Redmi Note 3) and is gettin hot too.

My charging temperature is 43 degree Celsius using stock charger, I search on Google battery should be charged between 5-45 degree Celsius, so I think it's quite normal.
What's your charging temperature?
Around that too man. Thanks
I think it's not necessary to use quick charge provided by original charger most of times.
During night for example using a normal charger will warm and therefore damage much less the battery

Recently bought lg g4 used so it comes with a conventional charger .... It takes 3.30 hour to get 0-98%
So i borrowed quick charger 3.0 now it is charging really quick 5-75% in 1hour but cpu temps becomes high 45° to 58°C & battery temps remains normal 15-18.5°C
So i wanna know are these cpu temps normal during charging or not?
Thanks in advance
I haven't monitored mine to know for sure, but it feels warmer near the CPU area, but cooler toward the battery area. Perhaps also look for a circuit breakdown analysis to confirm that the charging circuitry might be located near the CPU, so the charging circuitry gets warm it also warms up things around it, like the CPU?

Yes your cpu and battery temperature are normal...
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.

Hi guys so the note 9 is becoming hot while charging it has started happening the last couple of days. When I first got the phone on release it would never get hot. Any ideas?
Sent from my SM-N960F using Tapatalk
Have you noticed any change in charging times? That heat = wasted electricity which has to come from somewhere. There is only two places that heat could be coming from (afaik) are the processor or battery and it's charging circuity. Could be that the phone is doing a bunch of updates when you plug in the charger, if you have auto updates on or perhaps you had fast charging turned off before.
No updates phone has all connectivity turned off back gets really hot and yesterday the charger stopped charging the phone so I got the charger brick replaced and charges fine but seems very slow to charge and fast battery discharge

Turn off fast charging. I believe, even normal slow charging is fast compared to iphone 8 plus fast charging.
charging any device while it's on will probably produce some heat.
just seems logical and I don't consider it an issue worth worrying about. it all depends of what your measure of hot is.
if your cable, port and charger are all mint, then all should be good.
if your cat bit the cable then look no further.
your alternative:
shut phone off and charge it.
it won't heat and probably charge in 20-30 mins to full charge from 0%
if it still got hot while charging at off then you may have hardware issue with equipment/phone

The heat is caused by the charging process, so the phone should heat up whether it's turned on or not. The voltage has to be dropped from the 5/9V input down to the ~4V that the phone battery charges to and that is not a 100% efficient process. The internal resistance of the battery itself also causes some heat.
Also there's no way you'd charge a Note 9 from 0 - 100% in 20-30 mins. Even factoring in no charging efficiency loss, you're looking at 51 minutes to charge a 15.4Wh battery with the 18W from the Samsung charger.

I dont need any convincing lol
but the heat we can actually perceive on the phone case while it's on versus it's off is 2 things. dont think we can feel it while it's off. if I crack the phone open and touch the battery then yes obviously.
now for the 0 to a 100 in 20 to 30 mins while phone is off, I'll time it. but I'm pretty sure I'm not off by that much. again I'm not the one needing convincing in this thread.

Your phone should be almost exactly as hot whether it's turned on and not being used or turned off. The tiny amount of energy it takes to run a phone while it's dozing is nothing compared to the amount of energy dumped into the phones body while it's charging.
I'll happily test it but unless the charger suddenly starts outputting more than twice the rated amount of power into the phone when it is turned off, it's just not physically possible. Not trying to convince you, just trying to correct misinformation.

while powerdoff :
60 min = 81%
and it did get warm
guess we live and learn.

Mine is becoming a little hot while in wireless charging pad, and after complete the charge (at 100%)
That is normal however it should cool down once your battery level is charged above the 50% mark.
Try installing a battery log app. I use this one and it records battery temp so you can look at that after it is done charging to see how hot it actually got.

Perfectly normal. Especially if you use the phone while charging (don't do that)
Hello there! I wanted to open this thread to ask what's your opinion on proper charging habits with this Si02 battery that our Mi 11 Ultra's are equipped with. I have been reading a bit on the issue, but all I can find is comparisons between ASM batteries (lead based) and Si02 batteries.
Should we be using the same 15/20% to 80% rule with Si02 batteries?
The most I could find is that they are way more resilient to 80% DoD's than other batteries, so perhaps we can move to a 10 to 90% approach with them?
Cheers
I don't like leaving home without 100%
Replacement batteries are cheap but you lose waterproofing when you install one yourself which is a good reason to take care of it if possible
It's so hard NOT to reach 100% with the 65W xiaomi charger that i have
I also observed another thing, when charging with a slower xiaomi charger ( the one that came with the mi9 ) the temperature gets higher until it reaches the 90% mark than the 65W charger.
This was clearly observed via the Accubattery pro app that i use.
I'm curious to see hot it will be with the wireless (80W) charger.
Cheers !

Given the fan the 80W charger has, I take it will probably run quite cool..!!
I am personally also using the 67W charger and even tho it gets hot, accubattery shows it as being completely fine.
That charging speed is amazing, and indeed, it rlly is hard not to reach 100%. I was using a 33W charging phone before and it was already hard to some point not going over 80-90% .
I am personally going to try keeping the DoD between 60% to 70% if possible, but I feel like this batteries deal with DoD better than Li-ion batteries
If you want to control your charging/discharging, I found an app on Play called Plug Sound. It lets you change a lot of system sounds, but will also play a warning sound when battery reaches High/Low charge %age.
The plugged in/unplugged sounds work well with my wireless charger so I know I've positioned the phone correctly.

Or, if you're rooted, you can install this app from the Play Store, that limits the charge to a set percentage. You can also find it on this thread. I've been using it on my OnePlus 6 and it works great, stopping the charge at 80% and resuming it if it falls under 78%. It's the first thing I'm going to install when I receive and root my Mi 11 Ultra.
Im planning to use a 18W charger to lessen the heat from the phone and to increase the life of the battery from using the 33W brick. Is it okay to use a different charger brick?
yes, I got this phone less than a week ago and charged it two or three times, and didn't use original charger yet, so no worries, it'll work ok

Same here. I also use other charger and did not use 33 w charger yet. It charges fine without issues but a bit slower. It is up to you to decide to use 33 w or lesser w charger.
It won't effect anything except if you want fast charging.
If you can software disable fast charging it doesn't matter which brick you use.

Too bad. Not familiar with that brand at all.
Usually it's getting fast charging to work rather than the inverse.
I think I would rather have your dilemma.
My phone doesn't charge with 33W even with original charger,
So many users also complaining the same that it isn't charging fast enough
I use "battery charge limit" magisk module to limit charge limit
Or
You can use accubattery app to set alarm at specific battery charge limit
I use zmi charger 18w with pixel rom. Still recognized as fast charging!

Make sure the battery temp is at least 82°F before you start charging. I get best results with a start temperature of 85-95 F.
Keep the temperature under 100F while charging. Use cooling if needed. Fast charging will warm up the phone fast especially in high ambient temperatures... if will need cooling. A fan and/or damp microfiber cloth helps. Keep it of direct sunlight
Keep the screen off when charging as it will completely skew the charge curve.
A quick 2 second look doesn't seem to hurt though. Likewise I use bt and Poweramp to listen to music while charging with no perceivable impact on my Note 10+.
Play with it and see how it behaves...
Would a 10w charger also work?
