My tylt Qi charger heats my battery to 110F (updated). Ive been told that for some reason all Qi wireless chargers heat the battery this much in this particular device.
Please tell us your charger and max battery temp during charge. There are a lot of apps that will tell you max battery temp and here is the one I use
https://play.google.com/store/apps/details?id=com.fsinib.batterymonitorpro
Please charge from at least 50% down and give us the max temp during charge as opposed to the final temp at the end.
111F, 44C nokia dt 9000
110F, 43C tylt vu
106F, 41C koolpad
102F, 39C choe
102F, 39C google LG stock
102F, 39C DT-910
093F, 34C generic (need longer test)
090F, 32C ravpower (need longer test)
Thanks to everyone reporting so far!

ive heard complaints about overheating nexuses but mine only get up to around 34degree C which is something like 90deg F. that's with a case on the phone as well. i read a little about the Qi standard and the phone is supposed to command charging current so external interference or losses in the reciever coil don't cause the charge current to be lower than the the transmitter is regulating. so maybe some batteries are subject to inductive heating, maybe some phones have a short in the reciever coil. but mine charges to 100% and never gets hot....
I was charging with a Nokia DT 9000. Threw it on at 30 percent. A few hours later I felt it with my hand and it was rather warm so I checked the temp and it was 44C so I pulled it off.
Edit: in a Ringke slim case

34C is actually a bit over 93F, but much cooler than I have seen reported so far. Which charger and what temp reporting app?
ravPower charger. Went from 80% to 100% in 40 minutes. So half as fast as the stock USB wall charger but still better than I thought it would do. Temp never exceeded 90 degrees.
ok, seems the battery actually cooled while i was installing the app. i installed smart battery monitor. since i posted that, it went up to just under 96 degrees F.still no 108 degrees. but it has been on the charger for over 30 min strait and wasn't off the charger for long before that.
either way i have no problems with heat on my phone, it never feels much warmer than other phones ive had on usb chargers. the charger i'm using is a generic chinese charger. the box has no name brand. i also have a samsung charger but haven't checked the temperature with it. it doens't seem any different.

30 mins is not long enough to test it. You need to let it go from about 50% or less to full. The battery temp will vary a lot depending on the full capacity. My software captures the highest temp achieved during the charge because as it reaches full it will already start cooling down. You need to look at a temp graph of the entire charge cycle.
I just received my Nexus wireless charger and installed the free version of the app the OP linked, will charge overnight and see what the app says.

Sure it's enough. If you plan on charging from 50% or less to full then your battery will get hotter. Wireless or wired. It's just how charging works. More time=more heat. Your still well within the safe zone at 110 though.

Then why not charge it for 10 seconds? I'm just trying to get in a full charge cycle to see the max temp. And actually at the end of the cycle your temp should go down due to the way lithium chargers scale down at the end of the cycle. So charging a 95% full battery wouldn't tell us much.
Your linked article says damage starts to occur at 120F. Well, that depends entirely on the particular battery formulation. It's not something you can generalize. Lithium batteries are definitely not all the same. What you can generalize is that more heat means more wear even when below the damage threshold for the specific battery.
37-39°C from ~10% to 100% :good:

the phone was charging for an hour before that and it wasn't off the charger for "that" long. i'm not paying for an app i plan to use once and delete. sorry. i found a free app that will log it. i'll post results in the afternoon but the phone has never ever been warm enough for concern or even a second thought.

Thanks for your help. There's a free version of the app I linked and I also mentioned that there were many apps available that measure battery temp. I certainly wasn't try to get anyone to purchase that app. I simply made the link available because that was what I personally was using. If someone comes up with one that has better graphics please link it as I didn't have time to evaluate all the apps in this group.

I bought this for 30€ (~40$)!
http://www.amazon.de/induktive-Lade...TF8&qid=1385559057&sr=8-4&keywords=B00E5D70ME
It is small and has a rubberized ring and the phone stays in position! I can also lay a small bag between the charger and the phone (http://www.amazon.de/fitBAG-Handyta...qid=1385559718&sr=8-2&keywords=nexus+5+fitbag). The only disadvantage is that you need your own power supply unit for this!
I think the product is identical with this on amazon.comhttp://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias=aps&field-keywords=qi t-200
Official Google/LG wireless charger, phone was on it all night last night and highest temp reported was 101.5F and today while on subway and or roaming my battery temp hit 102.6F. This is with the bumper case on and phone in my shirt pocket under a jacket. I am inclined to think that if the phone gets that warm when roaming or searching then the charge temp is just fine.

That charging temp doesn't seem too bad to me as compared to the data from the other chargers reported so far. Keep in mind that high battery temp as a result of charging is much worse than rise due to ambient or discharge.
I think the jury is out as to how much affect high charge temp will have on the Nexus 5 battery. No one seems to have any specs and I think experience is going to be the only way to really know. I think we can safely say the temp rises significantly more than with the usb charger.
from what i've read about Qi i dont thnk the problems are with chargers unless they are just ignoring the charge controllers requests to lower current. the 5w charge power is supposed to be regulated by requests from the receiver (phone). so if the phone is heating it may be a phone defect like a short in the coil causing eddies and heating the coil. but i guess there can be factors with the charger...
ok second (this time proper) test with my generic chinese $18 charger.
30-37deg C, graphed out with Battery Info app. 27%-100% screen on the whole time with the phone in a case. thats almost a worst case scenario.
I get around 40 °C (104 °F) with either the TYLT VU or the Koolpad. I usually start at around 50% SOC and it peaks at around 90% SOC. After that the temperature drops a few degrees. I attached a typical profile with the Koolpad.

Hello
Lately( a week or so) I have been noticing that my phone is taking longer to charge. Before the charging took about 1.5 hours maximum from wall charger. Lately it takes more than 2.5 hours!
I took my charger and checked how much mA it was giving. The range is 770 to 330. On my Nexus if I use the charger, it gives stable 770-750 mA. So I'm sure its not the charger. Nexus 2.1A charger gives 900-980 mA if I use it to charge my Xperia but I'm afraid it might damage my phone.
I know as the battery is charged, less current flows and thus the value starts to drop but why suddenly it is taking more time to charge ? How much heat can affect it? (Really an extra hour if I place it over my microwave which is always off when I'm charging but it is sometimes it's a bit warm.)
Funny thing is I charged it at another plug with same result.(2.5 hours) but sometimes my phone surprises me and charges within 1.5 hours. I can't seem to find out why

Hi,
When I was using Galaxy S3, before I got the OPO, there was an app called Galaxy Charging Current that would, of course, show the current at which the battery was charging. Helped me a lot in identifying charging problems with that phone. I don't have any problems with charging, but do we have a similar app for OPO?
I've checked the GSam Battery app but it doesn't show charging current. Any help would be appreciated.
Thanks!
Mods: If this thread belongs to the Themes and Apps forum, please move. I posted here because this is a question.
Try battery monitor widget.
Transmitted via Bacon
I second battery monitor widget. It supports the OPO specifically.
Quick System Info Pro. Gives you charging, discharging and a lot more info in the notification drawer.
Thanks all for your suggestions.
I'm trying out the battery monitor widget right now but it doesn't seem to show the correct current numbers. I mean, I am using the wall charger and the current jumps around between 800mA and 1050mA. The wall charger is charging fine and fast, so, it should be around the 1800 - 2000 mA mark, right?
Will try the Quick System Info Pro in couple of days and get back.
Thanks!
It's jumping because the charging current is not a constant value. It's regulated according to the current temperature and number of % of juice your battery currently has... maybe a few other things, but mainly this. The max current OPPO will take is 1,9A (1900mA)... you may see that result when your battery is really low and it's temperature not high, on the other hand when your battery is almost charged you will see low current draw, just enough to power your device and not be discharging the battery.
You should find an app that will tell you the max. current draw that it can take from a specific charger, and stay away from fake samsung chargers.. they are junk.

My OPO is only charging @0.8A (according to a volt/amp meter).
Although after flashing Boeffla (or AK) kernel, you'll be able to change the charging current. I changed mine to 1500mA.
Hello Guys,
when charging my honor 8, I have noticed that the back of the phone gets really hot; especially when charging is initiated at low battery(less than 20% of battery).
The battery temp gets up to 40C (104F), measured with Using Simple System Monitor app.
I use huawei Quick Charge that comes with the phone.
Is there something to worry about or is this common? I know that too much heat on the battery can cause its early failure.
Thank you,
John
high temperatures will affect the battery life over time, are you using the phone while charging or are there apps running in the backgound using the cpu?
I am not using the phone while charging. It is connected on wifi and no apps running on background.
That's really hot. And not normal. You can talk to the guys in service center for it.
40C to 45C for battery is normal guys while charge is droped and charging ! ..
same as for CPU Temp . 40~45 is normal when u r gaming .
above 50 is not normal . and yes if the battery is low and using charge try to turn it off or don't use it while charging ! ..
and i know since 2 years that a good way to keep battery healthy is to charge only when battery drop after 20% and charge less than 95% and never use phone while charging . will keep battery healthy ! .

Status update
With stock Huawei fast charger plugged in for 10mins the battery gets hot (around 38C) and the input current gets down to 300mah (from 2700mah). The wall brick charger is not hot at all. So I guess is something to do with my device.
That way the charging process will take very long time.
I tried a lenovo charger with max output 2000mah (I measured 1700mah with the monitor app). The battery seems to charge fine with it and not overheating. However, charge time from 20% is approx. 90 mins.
Summary, Huawei quick charging sucks...at least for me
Note: for those wondering if I have a faulty battery, I can get 4 hours of SOT so I assume that my battery is still good.
Quick charge only works on the Huawei charger. Quick charge works by pushing higher current to charge the battery quicker up to about 50%. My phone gets warm from charging if it's below 50% because of the quick charge. I've experienced this on all of the phones I've owned that had quick charge.
Honestly, it sounds like you may have a bad Huawei brick.
The Honor 8 shouldn't get uncomfortable hot while charging. It should get hot but not so hot that you can't touch it. I would contact on Honor about the problem if it becomes persistent.

This is a really old post. But I am making it for the benefit of people stumbling across this thread.
So I must say that info is incorrect.
You battery temp should not go above 42 while gaming and that is really too hot. Ideal gaming temp is 40.5C and battery idle temp should be between 33-35c
For Battery longevity
When charging, you really don't want to go above 80% or below 20% and its better to charge throughout the day sporadically than leaving the phone on the charger for too long.
Again , sorry for commenting on a very old post. But maybe the info will help someone.

But let me also ad that it would be wise to learn how thermals work and how to build your own thermal profiles for battery longevity.
Sent from my Xiaomi MI 8 using XDA Labs
Some iphones have this problem and my honor 8 is having this problem too. My battery has half of its capacity now, i'm waiting a new battery to replace it
So I bought POCO X3 Pro earlier this month...So I play games on it mainly and the question is which kind of charging habit is better?
1.Frequently charging to make the percentage between 50%-100%
2.Charge it to 80-90 and try not make to make it fall below 20% and charge only once in a day?
The second option is a bit far fetched for me...Though I will try
My habit is 1 + 2: when around 50%, charge it up to around 90%.
Of course I'm not paranoid about it. But I do check battery levels most times I pick up my phone, to decide what to do.
If you root your device, you can use Battery Charge Limit.
You can set the maximum charging percentage, like setting it to 80%, then the charger will stop charging.
For our POCO X3 PRO, we need to go into this app setting and change "Set Control File" to the one with mi6 or something I don't clearly remember.
ArrowOS has this smart charging built-in.
I personally use my old charger to charge it slowly.
From what I observe, the Xiaomi 33W charger will rise the battery temperature to 40°C, which is bad to the battery. My slow charger will increase to ~33°C.
The fast charge is for convenience and emergency eg. forgot to charge at night and need to rush in the morning.
Frequently charging between 40~80% is better for battery health in long term.
Advanced Charging Controller (acc) is a good module to do this under control. It also has links about battery health explanation. (Battery university)
It is best to keep it between 20-80 present and not gaming while charging. I use my old slow charger when i am not in a hurry.
i keep mine at 70% max. i charge when it gets to 40%. I use arrowOS so i can set max charging and it resets the battery stats as well, so i know which apps eats power next time
Trying to keep it between 40-80%, with 10min break before recharging to cool down
Actually, I always keep my battery between 25% and 75%, then I restart the device once a week. Finally, I will use it until 0% one or two times a month before charging fully to 100% , I have read in a newspaper, it is necessary for digital devices.

If you want your phone battery health to last longer for years, like 2 years or more, then it's better. Info is here: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
For long term, battery will degrade and loose it's capacity, so your battery die eventually, then replace, then die, then replace...
Like this:

If you are wealthy enough to change your phone so frequently that you don't even want to concern the long term damage to phones, then forget about it and go for the TOP. (And coffee for me )

To be honest, I wouldn't worry too much about any loss of capacity in the battery. My oldest still active device is now 5 years old and even with that I do not notice any significant loss of capacity. Typically all of my devices charge from around 5% to 100%. My Nokia 7 Plus was charged almost daily by me for 2 years and by my brother for a year before that, but I don't know how he charged it. Still, I haven't noticed any change in the running time to this day.
Maybe it's not the place to ask, but I was wondering, is there any way to know if a Xiaomi charger is fake? I want to buy a charger between 10-18w to replace my 33w charger in order to reduce my POCO X3 PRO battery's suffering, but I live in a third world country where is VERY difficult to adquire imported products and I don't want to buy a fake one from the local online marketplaces, if you guys could please help me I would appreciate it

Just buy any 2 Ampere, 5 Volt charger. It should be fast enough, but not too fast. It doesn't have to be a Xiaomi charger.

If you have a laptop, use it's USB. It most likely will charge VERY slow, to the point that you want it to charge faster.
Edit: The alternative way is to use Magisk module Advanced Charging Controller (acc)
You need to unlock bootloader, install Magisk, and install Advanced Charging Controller (acc) module.
Then you can restrict the charging current or voltage. I tried with the official charger and it can be charged below 500 mAh, so below 2.5 watts.

All interesting posts. I wonder however:
What about having the device connected to the charger most of the time (at work place) with 100% most of the time, so it is de-charged only a small time of the day? So only at times when really moving around some workdays or in the weekend the device gets down to 20% or below.
I have now changed the 33W (12V/3A) Fast-Charger with the older 18W (9V/2A) Charger of the RN7 I have.
Would setting the charge limit to 80% give a huge benefit if I would like to use the device at least for 2-3 years?

...
Cycling from 70 to 20 % we get 6.000 cycles
The first two are should be the standard user behaviour, given the ROM build-in recharging warning. The difference in cycles to 70 to 20 % seems huge (6-10x more)

Connecting to the power all the time at around 100% is bad. It is at the limit of Over charging, the battery may bloat up and destroy the screen.
If you want, it's better to set it limit 40~80% and connect. The importance is the battery temperature. Don't make it hot. You can check it with Ampere.
The benefit is about the battery. You might not need to replace it often when you encounter like cases of sudden drop of percentage or sudden shutdown.
Huge or not is subjective.

Regarding battery temperature at least after reaching 100% I never noticed a hot or even warm phone.
I taught the device/system has some "charging intelligence" when always connected, so that the phone is directly using the power from the cable while the battery is not drained?
In Stock MIUI (debloated) or xiaomi.eu without root it is not possible to set a different Battery Charge Limit then?

When it's about to reach 80% or 90%, smart batteries now will charge slower automatically, so you don't feel the temperature.
However, when you see it in ultra-fast charge, like 40% charing to 70% in 30 minutes, the battery rise to 40°C or higher (as I observed.) Can even go higher depend on climate and using while charging.

This can be done with Advanced Charging Controller (acc).
I had answered similar questions here:

This control needs root.
Unless it's built into the Rom.
ArrowOS version 2021-05-07 had Smart charging that can set a limit threshold without root.
But developer said will remove this funtcion. See in his Rom thread for his reply.
