The Atrix's default adapter in an 5v = .85A, while the Ipad's is 5v = 2.1A. Is it safe for the battery to use this charger? I also have been using the ipod charger on my atrix too, should i countinue to use the ipod charger or does that have negitive effects too, ipod charger is 5v = 1A
Atrix: 5v = .85A
Ipod/Iphone: 5v = 1A
Ipad: 5v = 2.1A
Typically, a device will only pull what it needs, amperage-wise. The ratings on power supplies are, to my knowledge, always indications of maximum amperage, not any form of 'forced' current. Thus, the only time you need to be worried is if it is lower than your device's required input. You should be fine with either.

That's correct. I actually spent a lot time researching that kind of stuff because I use electronic cigarettes and finding chargers for them was difficult. Anyways, as long as it's 5V it should be fine. They actually make AC adapters that are iPad "compatible", meaning that they are just rated at 2.1A but it still works with the iPhone which the OP has stated uses a lower Amperage.

Thank you, both of you.
Would it charge the same rate?
the fact that a device will pull as much as it needs is true, but that is true only to the devices, appliances, and anything that is using the electricity, not storing it - which is the case with the battery. any electrical device uses only as much power as it needs. for example: a 55watt house light bulb will only use .5 amps, (110 volts AC) even though the circuit is wired for 15 amps max.
When it comes to cellphones, the cellphone is the device that uses the power and the battery stores the power. during charging, battery will try to pull as much in as you will give it, unless there is a limiting factor involved. a limiting factor can be a charger it self, which will supply 1.0 amps, .85 amp max, or what ever the case may be. also there may be a limiting factor built in to the phones circuitry it self that would allow only so much to go through ( i seriously doubt though)
By plugging in to 2.1A charger, the battery will try to intake all 2.1 amps,
Pro: you are charging the battery in half the time.
Con: if it doesn't destroy the battery right away, the lifespan of it and usefulness decreases dramatically.
This is called overcharging the battery, do some research on that and you will find out that overcharging the battery is never a good thing.
2.1A is not enough to destroy the battery right away, but if you would have plugged in 5 or 10 amp charger, it probably would, i'm just saying this to explain the concept.
I personally do use a 1.0A charger that i have left over from previous cellphone (touch pro 2) and your ipod charger should be ok too, but I wouldn't use anything bigger then that.
a small experiment that you can conduct which may or may not work. compare the temperatures of the battery/cellphone while it is charging on .85amp charger and 2.1amp, when it is on a bigger charger, it should get a lot hotter, and that is what destroys the battery.
As far as my knowledge goes, i have taken enough classes about electricity and electronics, and have been working in the field for several years, so i hope i was helpful enough and explained it in simple enough terms for everyone.

I might have to double check that. There is a chance that there is some sort of limiting circuit between the wall and the charger for the Atrix... I am fairly certain at least laptops do so. I will see if I have a stronger charger and I will check the voltage across the leads in the atrix... if I can.
Its not voltage that you should be checking, voltage should be same in all usb chargers, about 5 volts, you should be checking amps

My mistake... realized that after I posted it.
Also -- I do not have any USB charger that is over one amp, so I cannot check this. If anyone has a mutineer and a more powerful charger, they could do so.
The important factor is the Voltage which is at 5V for both the iPad and Atrix chargers. Whether it is rated at 10W or 5W does not matter because that just reflects the capacity for the current. And the charger is "rated" at 2.1 meaning it can handle that current rather than meaning it will force it. The "draw" of current is decided by the phone itself, as long as the Voltage is identical, the other factors should not matter.
If you read the "Summary" here it will say that, with the iPad charger, you can charge an iPhone which is similar to the Atrix in charging specs:

thanks live4nyy, i never saw those before. with all the stuff described there, the only conclusion possible is that each device has its built in limiter on how much it will pull while charging, or apple figures that with a bigger charger your battery on ipod/iphone will still last you past the 1 year manufacturers warranty expiration date, but barely past that date, instead of lasting 3-5 years like its suppose to. what ever the case is with apple, i just hope we have a safety built in into our atrix phones. I guess the only way to find out is to actually check the amperage while its charging.
I'm almost positive that the lithium batteries in phones these days are "rated" for specific current and have built in circuits that dictates the "flow", which is also the same thing that causes the battery to go into a "trickle" charge when near capacity. Just for that there has to be some sort of "regulation" happening. See also here:
http://science.howstuffworks.com/environmental/energy/question501.htm
But I agree, better safe than sorry. If you happen to have an iPad charger that you plan on using let me know how it goes. I'm curious as well.

Any USB wall wart that is 1.5 amps - 2.1 amps (1500 - 2100 mA) @5 volts will work. The more amps the faster it will charge. In a pinch you could use a 1000 mA charger, it will just take longer.
Alright im confused.. Which is faster mA or A?
And by the way im not asking about the power here but a replacement.
Thanks for the infos though

Congrats, you passed electricity 101.
Keep in mind that batteries can be fickle creatures. Sony delivers the XTZ with a 1500 mA charger. Based on that alone, it's probably best to replace the original charger with another 1500 mA charger. While you can certainly use more than 1500 mA and it will certainly charge faster, in the long run you may end up shortening the battery life. There are only so many charge cycles to be had in any given battery and quick charging can put an extra strain on a battery that wasn't manufactured to suck up power that quickly.
In a pinch, use whatever you have on hand or can find. For everyday charging, its best to default to what the manufacturer recommends.
The Apple 12W one works perfectly fine and charges the tablet so much faster!
There is people here saying it is impossible because of battery electronics.
It's quite simple: They're plain wrong.

Without doubt the best charger I've used for the money. It keeps up with battery drain on heavy use (Full HD video+Net+ others...at the same time) Stock charger does not. At first glance it does seem expensive but does the job very well.
I sent Sony a link to the Apple website for these as it's much better than the POS charger they give you with their £400 "Flagship" tablet. Well worth the £15 price tag.

Well, yes and no. Watts, Amps and Volts are all different measurements for different things and it can be quite confusing to figure out to the uninitiated. Watts is a mathematical calculation based on Ohm's Law. Watts = Volts x Amps
All USB devices accept a maximum of 5 volts. USB standards cap the max power delivered to a device @ 5 volts. Most standard USB ports deliver 5 volts @1 amp. Newer computers and specially designed charging ports can and do deliver more than 1 A via USB but they all deliver a maximum of 5 volts.
12 watts divided by 5 volts = 2.4A
If you look at your charger you'll see the output amps listed as 2.1A or 2100 mA.
Sony's included charger only delivers 1.5A or 1500mA, so yes it charges slower and when the tablet is under high load, has a hard time keeping the battery at 100%.
The real concern here, is what effect does delivering 2.1A of current to the battery day after day have on the useful life expectancy of that battery? I don't know the answer because I don't know anything about the battery that Sony uses. It's possible, if Sony, used a top quality battery, that charging with 2.1A will have no effect at all and Sony just wanted to save a buck or two by including a weaker charger in the box. On the other hand, Sony may have deliberately used a battery designed to accept 1.5A and included an appropriate charger.
As I said in a post above, apart from the battery overheating while charging (if it wasn't designed to charge @ 2.1A) and a reduced useful life of the battery, there shouldn't be any real problem using a "slightly" more powerful charger - up to a point. Charge with too many amps and the battery will probably explode or at the very least melt, potentially causing a fire if left unattended.
When talking to Sony, the question you need to ask, "Is the battery rated for 2.1A or only 1.5A?"

Definitely. More current (which is what Amps measure) means faster charge times, as long as what is being charged can accept the current being provided. You should be fine, but what do I know. PM me in six months and let me know if your battery still last a reasonable amount of time - then we'll know.

You're kinda right, but kinda not....
The charging circuitry inside the tablet is what regulates the charging current, not the 'charger', it will have min and max currents (the thing we plug into the wall that we all call a charger, is really just a power supply, there's no charging circuitry inside it.) That's why it doesn't charge from a standard usb port (which is 500mA) so, if it's charging faster with a 2.1A power supply, then it's obviously designed to do so.
Let's say, for example, the tab can accept a charging current of between 700mA-2.5A. Obviously, the charge time will be slower at 700mA than 2.5A, however, if you were to plug in a 5A power supply, the charging circuitry in the tablet will still only draw the 2.5A its designed to. So, don't worry about giving it too much, it's not possible.
Now, I don't know what the min and max charge currents are, but I can tell you that mine will charge (very slowly) from a 700mA LG charger.
And also, the dock for the tablet states an input of 1800mA,
So, we can assume the min is at least 700mA and the max is at least 1800.

technaudio,
That's my age showing. Back before some smart guy invented the wheel, we gave a device power and if we gave too much a fuse would blow. I didn't mean to imply that the charging circuit was contained in the wall plug but at the same time, I failed to appreciate that the Tab was designed to prevent an over current situation.
...now let's see what happens when I give this puppy 15A AC...damn, melted the usb cable...

I knew what you meant, but some others on here probably wouldn't.

I wish a charger better than the original one if possible, with EU pins, and with a good quality checked (I prefer to avoid some product with awesome specs but not tested ...)
So anyone have any idea where I can find a good charger, and without any risk for my phone ?

If you want proper charging, then always use the accessories coming with that product. It is tested for sure and good. Other than that, you can use any charger delivering the same charge. The original charger is 5 volt, 2 Ampere. Don't use anything above 2 amperes as it may damage the device. Below that will charge it slowly.
BTW, why you don't want to use the original charger?

Can you test it with ampere (free in gplay) i don't think it will charge over 1800mA so that it acts like a normal 2a charger
Fast charging
Using a fast charger will destroy your battery faster. Not recommended as the battery is not removable. You can get a battery and if you are comfortable removing the back and swapping it out then go for it.

that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.
Since battery is not removable be careful with fast charging, since it will decrease the life span of the battery and in the end it will just give you less battery performance.. it is stupid... however.. there is situations where it can be really needed though but not on a regular basis..
Last weekend I would really had needed fast charging.. It forced me to spend about 3 hours on a cafee so I could make it 100% so I did know I did survive the day with gps and all other things.. However in these situations I really like the ultra power saving mode..it saved me that night.. when I was lost in stockholm.. and my phone was really the only way to get contact with people

Why don't you buy a powerbank? I can advice you the xiaomi 16000mah. That one charges fast and you can be mobile.
Any recommendations?
I wonder if a S6 charger do the trick. Stock charger is too slow damn. Spending 3 hours to have a full charge is not acceptable for me.
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps. Batteries will automatically lose cells from charge cycles and by the time you feel the effects of the battery going bad, you would have already moved on to the next device for the next person to worry about. And saying to use the Stock Charger isn't really good enough as the Stock charger doesn't serve as a Car charger also. If you want to charge your phone quick, and you already have a 2 Amp charger, Check your microUSB cable. Don't use junk cables, buy quality or use the cable you received with the device. You get what you pay for. Fast Charging won't work as the Charger has a chip inside that communicates with the Phone and Device. Also, when buying a charger, don't just randomly buy a charger online, Make sure its UL Tested. Even if it says UL tested, there should be a test number on that UL Label, take it a step further and google it and make sure it matches the charger specs and passes as knockoff chargers are notorious for copying other chargers Regulatory icons to make it seem authentic. You don't want to buy a junk charger that ends up burning your house down or gives you a very bad 120 Volt shock through the microUSB cable that would also kill and fry your phone.

one friend conected his phone to a hi suite, he went to repair sistem or something like that, and it pop out an option of QUICK CHARGE... even he doesent know how that hapends, now his phone charges faster. he is on b331 rom

Hi,
that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.

You have not read my earlier post or you did not understand it. Changing the charger on the Mate 7 will have NO effect (zero, nada) on the time required to charge your phone except the charger delivers less then appr. 1.6A. Then it would take longer and evetually kill the charger. The Mate 7 uses a Kirin chip which has no fastcharge implemented. Samsung uses Qualcomm Chips with implemented fastcharge technology. The charger (in fact a power supply) and the phone/CPU/charge controller need to communicate with each other, otherwise fastcharge will not be activated (the reason fastcharge with charge-only cables does not work because they lack the required data cables for communication).
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps.

Wrong. Correct would be "I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v." The amps of the charger don't matter at all -> amps are PULLED by the phone not pushed to the phone. You could use a charger with 100 or 1000 amps and it would not hurt your phone a bit as long as it is only charged with 5 Volts.
More amps (>1.6A) on the charger do not improve the time for charging one second.
1.6A is nothing. i use 2.0A and it still chrges 3 hours.

Yes, and that won't change one bit even if you use the best and most expensive charger and a 1000$ cable. The Mate 7 is limited by its hardware (built in charge controller) and pulls max 1.6A. End of story.
As long as you don't understand how charging works you will spend 100's of bucks for cables and chargers to no avail.
The only reason, why charging with some charges is quicker than with others is that those chargers actually deliver the amps they are supposed to deliver. There are a lot of cheap/bad chargers out there which are labelled with 5V/2A but only deliver a fraction of the amps. You can identify those chargers easily because they get extremly hot. I use a 2A charger from Aukey which gets only lukeworm.
Do we know for sure why it is that dash charging only works work the dash cable. Is it a DRM issue or a design element that needs to be licensed.
I'm not too stressed out because I plan to use a standard usb c cable for overnight charging but I am curious what is actually going on inside this charger.
I am quite familiar with OP official response concerning the matter, but given their track record of non answers, I'm assuming this situation is no different.
In other words I am curious what stops a company from releasing a cable that would in fact work. Possibly with the addition of some end user kernel changes. I understand this would be slightly impractical for a large company like Aukey or Anker to release a cable for one phone (that people could not use straight out of the box) however, my curiosity is still there
https://www.androidcentral.com/dash-charge has a good article on this.

Also, supposedly it's the same tech as http://www.oppo.com/en/technology/vooc - and anything "VOOC" branded will provide the same "dash charge" speeds.

Simple Answer to this is the proprietary high amp usb type c cable which is supplied with the stock 5v 4amp power brick work well hand in hand, it is the way Oneplus has made this..one cannot work without the other so it is packaged deal..take it or leave..unless you are willing to compromise DASH Charge you can use any other type C cable and power brick adaptor
On a standard type-c (USB 3.1) cable connected to my PC, the phone slow charges. My other devices fast charge on this cable.
The other devices slow charge when connected to Dash cable and charger.
It leads me to think some very non-standards conforming USB tech is going on in the Dash gear, enough to make Benson Leung sick to his stomach. This isn't new to OnePlus, see https://plus.google.com/+BensonLeung/posts/JmcU4rA1csh
My advice would be to never use Dash gear with other devices.

AFAIK this non-compliance thing has been there only in the first shipped cables and was fixed later on. So today's devices (this is already 2 years ago) should be compatible to USB standards and therefore other devices should load their battery at normal speed (not dash-speed) with the dash cables and dash plugs.

Should, but I don't think it is. Q: why would the OP5 not fast charge over a normal type-c connection if it were standards compliant? Answer: it doesn't comply with standards.

Amswer: OP5 doenst support any other quick charge methods (aka. QC 2.0/3.0, Adaptive Charging, Super Charging etc). It only supports normal charge or dash charge (& Vooc as dash is based on Vooc).
Also you should remember that different phones shows differently charging methods. Example Oneplus can maybe show normal 2A slow and Samsung as normal charge. Nexus 6P will show regular 3A charging as fast charging, Oneplus shows it regular charge.
For me if i use other C-cables (non-Dash charge one) it shows just "charging".
Regarding to Benson case... Original OP2 cable was non-standard. It didnt contain regular 56ohm thing. Oneplus fixed it later and dash charge cable is using standard things and also only for 3/3T/5 dash charge properties. For other phone you can use it without problems like use it to charge QC3.0 phones etc.

My point isn't so much about the cable as it is the device itself. It is a USB type-c device that doesn't conform to type-c USB standards.
There will be a plethora of usb-c ports on computers and chargers going forward. They are included on every new model of Apple, PC motherboard, and OEM PC - so type-c adoption is there and real. By ignoring these standards and producing a product with a proprietary design they are ostracizing their devices, and by extension their users, from simple and convenient charging methods. It ensures lots of sales of Dash chargers though.
It's a **** move straight from the Apple playbook. Apple made billions from the 30 pin to lightning connector change, and they will do it again with the lightning to Type-C change.
This Oppo/OP Dash charger isn't something consumers should be championing. It's not something Oppo/OP should be forcing on consumers either.

I don't think your statement is accurate, the newer USB C Power Delivery specs allows voltages up to 20 volts and amperages up to 5 amps, the dash charger specs use 5 volts on 4 amps, well within USB C PD specs. The fact that their technology is proprietary does not mean it's not standards compliant.
There is also the very important difference between voltage and amperage, voltage is pushed to devices so it's always important that what you are using within the voltage required by the device. Amperage on the other hand is pulled by the device so the charger will allow the device to pull as much amperage as it needs as long as it doesn't go over it's own capacity. Think about your standard US outlet, it works at 120 Volts and at either 15 to 20 amps, you can connect as many 120V devices to it as long as you don't exceed its amperage.
That being said, the reason other usb cables don't work on the dash charger block is because the usb A side probably has different resistors, One + cables probably have higher resistors than regular, run of the mill usb C-A cables. That was the issue with the first cables that came out a few years ago, they had pull-up resistors with the wrong Ohm rating.
Here is a link to a PDF file explaining USB C Power Specs, keep in mind though that the eventual idea is to only use USB C-C cables and not the USB C-A cables that are the cause of so much headaches.

The listed power specs are only half the picture. The negotiation between devices is critical in getting those power numbers. That a OP5 can't draw above 900mA on a fully compliant 3.1 cable from a PD capable Type-C port shows it's not compliant. Its not negotiating power draw the way a standard Type-C device should.
And yes, I've already read all the spec docs. Thanks though.

The phone itself doesn't have to comply to anything, the chargers and cables do since they are the ones providing the charge. The standards are there to determine thresholds on how much and how little current they can work with. The circuitry on the phone and battery are the ones who tell the charger how much current they need to charge the battery without warming it too much or overcharging it. Different combinations of chargers and cables will give you a lot of different charging speeds but that's because there are so many chargers and cables with different ratings that devices err on the side of caution when they can't recognize the charger that it's being plugged into them. It's kind of a unfortunate thing that companies like Motorola, Huawei, OnePlus and Qualcomm use different charging specs but all of them work within the 15 to 20 watts of power for fast charging, so it's not a really big difference.
The reason for the difference in charging speeds between the dash charger/cable and other chargers is that 1 + charger offloads the current regulation to the charger itself rather than leaving current regulation to the phone, like other fast charging devices, that's why 1 + phones fast charge at cooler temperatures than other fast charging technologies.
Now, why your phone doesn't go above 900mA on a regular cable is beyond me, the first photo I attached is of my phone connected to the dash charger via this cable and the second one is of the same cable connected to this wall outlet.

That's a fallacy. To comply with the standards does not mean, that everything is exactly the same. The USB-standard is a little bit more complex than just "pin 1 of one end has to be connected to pin 1 of the other end". The USB-standard defines what is allowed, so no devices will get damaged and to ensure a "minimum" data and power connectivity of let's say at least USB 2.0.
That's what these cables and chargers offer: They don't violate the USB standards. They allow a data connection with USB 2.0 also for non OP-devices. They also allow "normal power" (5V 500mA). They don't damage other devices. They just "work" as they should. But they offer "additional extras" (dash charging) when all three parts (charger, cable, phone) are compatible.
So they comply with the standards while offering additional features and that means, that other cables/chargers, which also comply with the standards but don't offer the extras, won't be able to dash charge.
Anyone tried to see whether using the oneplus cables on QC devices + QC wall plug supports Quick Charging?
I get 2a off my 3a rated PD c to c cables and 38w PD charger.
The only PD compatible android chipset I know of is made by mediatek at present.
I now have a couple Qualcomm 3.0 fast chargers, the fast charger from my LG G5, and the One plus fast charger. Only the One plus charger indicates that the 6T is quick charging. My question is if the other fast chargers are still faster to charge this phone than a standard charger.
Thanks

They will charge faster than an old .5 amp you may have kicking around in a drawer. Realistically they will charge fast enough because how often do you need every drop you can get as quickly as possible? On the occasions you do need that you just take it to the dash charger and all is good. It's not just me saying that, there was a thread on a previous OnePlus device where someone else said what I just did and the agreement was unanimous. I couldn't argue it myself, I had found just the same to be true; I was typically in no hurry to charge the device and when I was I just made a point of going to the dash charger. I'm not sure what your use case is but if it was to go all dash all the time you may want to consider waiting a little and seeing how it plays out in use. I think you'll find your ok with just the one that came in the box or getting a second for the office or cart and calling it a day.
Someone not only do you need the charger you need the cable to? That wasn't explained in the article. Can you clarify?

Where does it say if it's Dash Charging on the phone? With my Note 9 I can see if it's quick charging or not, depending on charger.

You're probably not going to see the term "Dash Charge" anywhere,since OnePlus stopped using the phrase.
Whether they replaced it w/something else to indicate fast charging is anyone's guess (if there was any indication of Dash (fast) charging on previous OnePlus devices).

You will see a lightning bolt in place for the battery icon when Dash Charging is active, and if you plug in the Dash charger while on the lock screen, it will also make a short blip noise with an animated lightning bolt. Standard chargers and/or cables will show the lightning bolt inside the battery icon. You can always look at the charger current using the *#808# menu though.
Wait does the cable really matters? from the article linked, looks like the tech is only in the adapter
It matters because if you don't use one designed for it you wont get Dash charging, and yeah, its irritating that we have drawers full of cables that we cant use. As to the question of how you can tell, it says "Rapidly charging" on the lock screen. You'll also notice the phone gets charged stupidly fast, that's a big tell.

Yes it does. Pushing 4 amps to get more watts requires low resistance cables, otherwise the resistance will limit maximum wattage. With QuickCharge (instead of DASH charge) voltage is raised instead of current, mitigating the resistance problem.
For QuickCharge there also a handshake telling both the phone and charger that both devices support a certain charging standard. Only then current (or voltage) is raised above normal USB levels. Otherwise you would risk destroying devices which are not capable of fast charging.

Tragic...I invested a lot into my PD chargers for my 2xl guess I need to update everything again
But do you? How often do you NEED dash charge? You can still use all the other charges, they just won't charge as fast, but that's not a bad thing if you are not in a hurry.
The Dash charger works the fastest, however my Quick Charge 3.0 car and wall chargers are still delivering 2 to 3 times more m to my OneTouch 6T then my Galaxy 8 (Rated for Quick Charge 2.0) ever took, that is using higher end usb-c cables but not the Dash cables.
The Highest I ever saw my s8 take was 1300 mA, this 6T will take 2300 mA from my QC 3.0 car charger and 3200 mA from my QC 3.0 wall charger, as long as the battery is under 70%. However, the Dash charger with Dash cable gets around 4800 mA but it seems to fill the battery at a more rapid pace then what I would expect for that amount of power going into it.
The Dash cables have more pins in them to deliver segmented power, at the proper voltage and amperage, to partitioned batteries simultaneously in the 6T without it causing your phone to heat up.
