Is this normal? Seems like it's not very efficient after reaching full charge.
Yes it's normal. Whether it's efficient or not....
It's normal for all qi wireless charging devices.

Yes, it's an inductive and some power is lost in heat.
- the warmth after charging is normal -and if the surroundings are hot, at a certain temperature, it will stop charging.
my watch couldn't go past 94% for 3 days....
and in another post in XDA I read that its due to overheat.
I charged it in my AC room and its good after that.
- the warmth after charging is normal -
my 360 also warm after removing charger, and in 10 mins it back to normal temperature

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.

Hi. I am using the bundled moto turbo charger with my phone and have noticed that the phone sides and back get hot mid-charge when charging and cools down when the battery is about 80% full. Is this a problem with my phone/charger or does it happen with you guys also.
Its cause of the Turbo charger
That's absolutely normal. Don't worry.
Yup happens to mine too. Heats up quite a bit and then cools down after a while
Clean your charging jack once with hot gun with paste.

No need to be worried then as its common for everyone. Thanks.
It's completely normal, phones from ~2-3 years ago (before quick charging) didnt have this problem because they didnt have to dissipate the heat generated by forcing 15 (moto Z) to 25 (moto X) watts into the phone. Phones pre-quick charging only took in ~5-10 watts which is much easier for a phone to handle, although its also much slower. If you dont need to quick charge I would recommend using a normal power brick which will charge it slower, but also generate less heat. Some people think the heat can cause the battery to lose capacity quicker, while manufacturers say it doesnt. Honestly I dont know which is true so I cant say. I personally so far have charged over night on usb (~2.5 watts) and its done charging my phone and my moto mod by morning from <30% to 100%.

No need to worry, that's completely normal. The phone turbo charges until it hits the 80% mark, then the turbo stops and until 100% it charges normally, like any other phone, so it doesn't get hot. During the turbo charge it's normal that the phone heats, as it uses more power to charge faster, and from 80 to 100%, it begins to cool down, because it uses less power to complete the charge.
Normal
compared with x style
z play is nothing:laugh:
A potential work around
I realized that if you remove the back cover (style mod) while charging and keep the phone a little raised from the surface the extreme heat is not experienced.
You could try and confirm.
Hi,
Is it possible to turn off the dash charge? 5T is charged only overnight cause it can last the whole day anyway.
PS: I can turn off Fash Charge in my Samsung Note. So it saves battery if I charge only overnight and don't need fast charge feature.
There is no stock option for this. Maybe a custom kernel can support it or a custom kernel that doesn't support it at all would also be a possibility in theory.
I would suggest using a normal power adapter instead of the Dash charging one. Even a normal USB C cable prevents Dash charging as it can only be used with OnePlus' own cable. So maybe get a cheap USB C cable and use that?
Use a low amperage charger. Something like 1000mah. This will slowly charge your phone overnight. But make sure you use a quality charger.
Why would you want to do this? The OnePlus dash charger works differently from other chargers in that it holds the heat in the charging block. If you use a standard adapter you would transfer the heat to the phone while charging. I would NOT recommend doing this.

I use an Anker IQ 6-port Charger with a couple of fairly good quality cables.
I personally try to avoid any kind of fast charge because it will end up damaging the battery life faster than "standard" charge, even if the heat is absorbed by the DASH charger block. IQ Charge adapts itself with the needs of the device connected.
And my unit stays cool if I touch it while its charging.
Charge however you want. But for me, dash charger while getting ready in the morning or when you have a free half hour. Forget about charging overnight. I don't know your usage but for me, this works. The phone just sits on my nightstand without connecting overnight and I lose a very minimal battery amount.

It's fine at even less than 1 amp. We have two 5Ts in the house and charge them at night at 0.35 - 0.45 amp.
I saw the dash reduce Ampare when pass above 80%.
(When not rush I use official iPhone 1Amp charger.)
Use 5V/2A standard charger to standard usb type c.
Oneplus 5t = 5V/4A
Quick Charge = 9V/2A
Dash n QC have more power!
I'm using an old 1A Samsung power adapter and dash charge cable and in addition I also use Battery Charge Limit app to limit charging the battery to 80%.

No, it does not, especially not with dash charge. The excess heat is stored in the charger and is not transferred to the phone, and the heat is the only thing that degrades the battery faster.

Your informations are not correct.
Dash (or VOOC, which is the very same technology since OnePlus is an Oppo brand) uses high current fast charging instead of high voltage charging (QuickCharge 2.0/3.0 uses high voltage) and the circuit that produces heat in phones that are not Dash/VOOC compliant is inside the phone, while in Dash/VOOC is inside the charger.
Oppo and OnePlush themselves have acknowledged that it makes SAFE to use the phone while it is quickcharging, NOT that the battery is not getting damaged by the use of a fast charging method, even if it charges at a lower voltage and higher current.
The use of any fast charge technology implies to shorten out the overall battery life.

Just because they moved a bunch of the power regulation stuff to the charger doesn't mean the battery doesn't still get warmer. If you push 4 amps of current into it, it will heat up more so than when it receives, 1 amp.
Now you have me curious though, I guess I'll have to pay close attention to the battery temp next time I charge my battery. I've never used the dash charger, but perhaps I'll have to get it out of the box, and test with it as well just to see what kind of temps I see with a more powerful charger as well. I'm curious to see how much temperature difference there is.
I know on my Nexus 5X my phone always lasted long on a single charge when slow charged (0.35 amps), vs using the factory 3 amp charger.
Constantly topping up the battery overnight for 5-6 hours (assuming your slow charger will charge it to 100% in 2-3 hours) is worse than using Dash to charge it quickly in bursts in the morning and night when you have a spare 30 minutes.
I would never leave a phone stuck on a charger overnight. Especially since even the slowest charger in the works will charge the phone to 100% in three hours or so.

I don't charge my phone over night either but by using above mentioned Battery Charge Limit app it is possible to stop charging when desired battery level has been reached.

That would be a good idea to do. Although the best is to just Dash charge in short 30 minute bursts when you can.

How does it imply that? Heat is the only factor. Phone is not getting hot(ter than slowly charging) when charging.
What is the truth? With the rapid charging the battery deteriorates faster or better a slower charging?
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.
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.

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.
