hello. (first of all I use Google translate ).
I would like to know please if there is a way to limit the power that a wireless charger can produce. Or that the phone only receives a certain wattage from the charger.
To better explain. I have a Xiaomi mi 11. Which is compatible with wireless charging up to 50watt. I bought a wireless charger (the Mi 20W Stand)... I use an official Xiaomi 27watt charger. Which provides me with the maximum power of the wireless charger ( 20watt )
But the phone heats up quickly. I tried using an 18watt charger to got a maximum of 10watt charge from the wireless charger. But. The charger is limited to 7.5watt and the charge is slow.
So I would like to know if there is a way or an application to limit the phone to only receive 10watt from the wireless charger?
I don't thiink this is possible for any smartphone. Wireless charging produces heat just because of how it works. It'll always generate heat. Lots of energy is wated throught heat, which is why wireless chargers generally put out less power than wired.
I know on my S22 Ultra, there's a setting to turn off fast wireless charging. Not sure if the Xiaomi devices have something similar?

Thank you for your answer. I know Samsung has this option.but on Xiaomi no. I looked but nothing. and that's why I asked if there was a way to limit the charging reception on the smartphone. since it is the CPU that manages the battery charging

Are all USB car chargers like this? Can I prevent this by getting a higher quality charger? When I'm not using maps or navigation (or turn off the screen for a while), then it'll slowly charge back up.

GPS is usually a big energy hog. How many amps is your car charger?
You should be able to get away with a higher amperage charger, but the trade off may be reduced battery life.

How fast does it discharge? I just went on an out of state trip last week and had gps on with the charger plugged in for several hours at a time. I didn't pay attention to the actual charge numbers, but it either discharges very gradually or charges very gradually. I could probably run it all day with the charger and gps without a problem. I don't recall the amp output of my car charger, but it is one of the cheap foreign models.

Reflash your ROM, dude. I had that problem on one of my initial GB ROM's where I had bad drain using GPS while charging in my car. I redownloaded and wiped everything and reflashed the ROM and everything was good.

If you are running a custom ROM, you can use SetCPU (or any other CPU clock control app that allows profiles) to set max of 800MHz when plugged in. This should at least get you to even charge/discharge levels when plugged in and running GPS while driving. Probably will depend on your screen brightness.
I don't run GPS long term very often right now, but I was for a while and FWIW, I was able to stream pandora, run google maps with screen on, not have any lag, and get a slow charge from my car charger by limiting clock speed to 800MHz.
Your other option (and what I usually do) is turn off the screen during longer sections of GPS nav with no turns (like sections of highway). You'll still get audible notifications for the next turn/maneuver/interchange/whatever, and you can turn the display on then if you need visual along with audio nav. The phone shouldn't have any problem charging and running GPS with the screen off...

Not all USB car chargers are alike. You need two things:
1. The car charger outputs higher current than 500ma. You need at least 700ma.
2. The charger is wired correctly to be recognized by phone as AC charger instead of PC USB port so that the phone will actually draw more than 500ma for charging. You can go to phone's status page to read what charge mode it is using.
Most iDevice chargers will not meet #2.
I have a stock Samsung car charger and it charges my phone while using Google Nav.
Thanks for the tips guys.
My phone discharges at around 1% every 20 minutes or so. I've been doing things like turning the screen off during periods of downtime to help with this (actually charges when I do this).
I'm using cheapy car adapter actually that has two usb ports and 2 cigarette ports in it and I use that with a samsung branded usb cable.
Hm yeah I'll try and see if limiting the CPU will help and if it does perhaps I'll just do that from now on.

Do you know of any other options that are wired correctly to draw more than 500ma? I think I did hear from somewhere that charging via usb is considerably slower than when using the wall charger. Do you know of any other options that would fulfill this requirement besides getting the stock Samsung car charger? Also I assume just finding a higher amp charger wouldn't work if the phone detects it as a usb charger instead of an AC charger?

The correctly wired charger will typically short the USB data PINs. iPhone charges and most generic car chargers with UBS ports don't do that. Most HTC chargers and Motorola chargers will work on Samsung phones. You need take a look at your car charger to see how much amps it can supply (listed on the spec label). The PC usb can only output 500ma max per spec. It is not enough to charge the phone while keep the screen on, GPS running and 3G connection active. Your Samsung OEM wall charger is rated 700ma. So, you need a car charger that outputs at least 700ma.
You then need to verify from the phone that the particular charger is recorgnized by the phone as AC charger. Without that, the phone will only draw 500ma max.
Hi people
Since I'm part of the lucky people owning a Huawei Ascend Mate 7 (MT7-TL10), I'm actually looking some accessories like a quick charger.
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 ?
Thanks

for few days i went to jarir book store on KSA . I found Charger good price also 2 USB 5 volt 2.4 Amber ... compatiable with mate 7 and faster from orignal ...
just to know more fasting to charge wil damge your batter of mate 7 quickly .also orignal 2 A will damge
for me I charging with Iphone charge 1A good for batter and Stander and low risk to Device
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.

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).

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.
Hello all,
I have a really stupid question but it's keeping me awake...
The DashCharge charger, can I use it with other devices? Like a MP3 player? Or another phone? Or is it purely and uniquely proprietary for the OnePlus phones and it might damage the other devices I would use it with?
I know it won't charge faster the devices or... But if I can plug anything with it, then I can drop the other chargers I have and keep only the DC in my bag
Thanx for your replies
Dash power chargers work at 5 Volts 4 Amps which translates to 20 Watts, if I'm not mistaken, Qualcomm's Quick Charge 3.0 works at 6.5 Volts on 3 Amps which means 19.5 Watts of power. The difference in Volts and amps between different chargers is not an issue for most devices for two main reasons.
1. Amperage is pulled by the device, which means that if you have a charger with a 4 Amp capacity, you can pretty much charge any device that draws up to 4 Amps, since no phone that I know of besides the 1+5 and 1+3(t) draws that much, you'll be fine.
2. On the voltage side, most phone chargers (apart from Qualcomm's Quick Charge) usually work at 5 Volts, the same as 1+ Dash chargers. And even if the Voltage rating on the charger is higher than the phone. These type of devices have safety features that reduce the output if they don't recognize the device being charged as compatible with their technology.
So for a quick recap, if the phone you're charging is not compatible with the technology of the charger (1+ Dash, Qualcomm QC for example) the charger will make sure to reduce the amount of power being fed to the device to a safe amount. So normally a non Dash compatible phone will probably charge at no more than 5V 2 or 2.4A.
Thanx a lot for your answer
So I can plug to my DashChargers my MP3 players and lent them sometimes to my colleagues to charge their phones as well, with nothing to worry about. It's good to know

Yup, it just won't charge at full speed as it would with 1+ devices
You can use it with any device you like, but only OnePlus devices get the fast charge advantage!
Had anyone tried usb c power delivery charge yet?
I've got one for my cheap vernee which works well, in theory it requires negotiation to draw the correct power, but wondered if anyone has tested one yet

Hi!
I have a doubt, these type of USB-C --> USB-C charger can charge the S8+ quickly than the original charger provided with the device?
http://www.sony.com.sg/electronics/portable-charger-accessories/cp-ad3
I know that S8+ is not use the USB-C charging protocols and use Samsung AFC, because this my doubt if buying this will be a improve or only a waster of money.
Thanks!
I doubt that charger will be any faster than the Samsung provided charger.
Thanks, I get one to make some test. I install the Ampere app, I don´t know if this app is a nice measure tool, but is almost the same that original charger, also a bit faster. Original in test charger session show in the Ampere app a max of 990mA, and this Sony 1020-1100mA on different sessions on both.
I'm cool with the stock charger. I'm not trying to make my phone explode and burn my house down. I'll stick with Samsung's recommendation. Just because you CAN do something doesn't mean you SHOULD.
Original Samsung charger will charge your device at 9v whereas the Sony charger will only charge at 5v, however the new USB c standard allows 3A charging so the power you get from both chargers will be very similar. I use both types of charger and find it hard to find much difference in charge times. Ampere can't be used accurately as it's only showing the charge current not voltage and you need both to calculate power and compare the 2 accurately.
Hi Guys,
I know we always have to use the default charger but this is also a fact that the fast charger is not always good for the phone's battery life. We can use it sometimes when we are really required fast charging.
I have a Xiaomi original charger 5V, 2A. I use to charge my device 20-80% with this charger. My phone will not get heat up like it compared to the situation when I charge with a fast charger.
Please tell me, is there any problem if I'm not using the default charger that comes in the box with the phone? I'm using that cable but with the Xiaomi slow standard charger. Will it be safe for both the phone and charger?
Thanks,

I didn’t face any issue …but never use fast charging while playing high graphics demanding games.sometimes while playing games if battery low then i use 18 watt powerbank to charge while play…
yeah thanks for the reply.
sometimes, in the case of need, I will use the fast charger otherwise I will always go with standard 5v 2A charger.
