I have 3 different charger: a) the one that came with RN4 b) one that was shipped with my Samsung Tab S2 and c) a 3rd party charger from Anker.
All of them come with 5V and 2,0A.
What surprises me is: If I charge the RN4 with the charger b) or c) the battery gets warm - not hot, but warm, when the RN4 is switched on.
Why is that? Does anybody have an idea?? I mean, if they were some low-cost / no-name charger, okay! But that way I dont quite get it.
As far as In understand the higher the input( volt and ampere) the higher the heat grows.
I think the original Xiaomi won't output the maximal charging volt and ampere the battery can process.
Are b) and c) faster then the Xiaomi?
Hi, I understand why you are asking. But as far as I can tell, there is no difference in charging time. Actually, I havent took the time, but it doesnt seem to be longer or shorter with the one or the other charger.

The stock charger from Samsung was for 0.7Amps and it charges ok, but I find it slow.. about ~4 hours to fully change my SGS2 from with less than 10% left of battery life.
If I plug into the laptop, it takes like ~6 hours due to the slow trickle charge with 0.5Amps.
I don't know what the max pull is allowed on this phone, but I did find that when I charge with a 1Amps charger, I can get it from less than 10% to full in about ~3hours.
So, I tried a few such charges and have noticed some strangeness.. (all with the same test conditions, start charging with less than 10% and with the stock usb cable for the phone)
1) older Belink ac-usb 1Amps out put, it does seem to charge the phone good and faster finishing around ~3 hours ... but, when charging, the touch sensitivity of the screen is out of whack, any subtle movement, will cause the screen to jump around.. like in gallery, trying to select an individual pic is difficult as the screen jumps around; forget about using the browser and selecting links...not sure why..
2) HTC thunderbolt charger 1Amps output (http://www.amazon.com/gp/product/B003WM6SOU).. same issue here, charges faster, but makes the screen jump around
3) iPhone charger 1Amps output; this seems to work the best for me so far.. charges faster ~3hours and while charging the screen behaves normally, I am able to use gallery and browser fine...
4) iPad 2 charger 5.1 V and 2.1Amps: Still charges the phone ~3 hours, but same side effect...
Anyone else have the screen sensitivity issue and what chargers are you using?
I haven't seen any issue when I used a HP TouchPad Charger rated at 2.0A I think..
Max pull is 650 mA - this is set by the charger chip itself.
If the phone thinks you have a normal USB connection to PC instead of a dumb charger, it will be 400 mA.
Having a charger rated more than this won't hurt, but it won't help.
Monoprice "1A" car chargers are rated 300-400 mA at best - the ONLY monoprice product I've ever been unhappy with in my life.
In general, you want to make sure USB D+ and D- are shorted together by the charger - this guarantees that the phone sees the charger as "dumb" and goes to 650. Exception are media and car docks - whatever you connect to these will be assumed by the phone to be a high current "dumb charger".
All phone power usage (CPU, screen, etc.) counts against this current budget - e.g. if you have 200 mA of load, only 450 will be going into the battery.
Unlike the I9100, we don't appear to have any way to change these charging currents. Our phone, for whatever reason, has an additional chip for charge control (MAX8922) instead of using the charge control built into the main power management chip (MAX8997). This is disappointing, I was really hoping to bring over the "charginghacks" modifications from my Infuse kernel series.
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.

Click to collapse
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.
I know there is a thread about what charger to buy, but I have a specs question. Mine z5 came with the International charger and I am in the US. I noted it is 5v and 1.5a. I have a 5v 1a charger on hand. Can I use that?
Sure, it will just take longer to charge.
No lasting negative effects on the battery?

Most certainly no negative effects. In theory it should actually be better for the battery to charge it with less current, but I don't know if that is true.
Different topic: I read that there are multiple versions of the Z5 (US, Europe, ...) and that they support different LTE frequencies. So maybe you want to check if your mobile connection works as intended, if you don't have the US version.
My phone is showing LTE after choosing my apn settings.
I tried using a 5V 1A charger with my phone and it doesnt seem to work. (It works fine on my old phone) The charge light keeps turning on and off. The vibration pulse you hear when it starts charging keeps pulsing too.
Better use an HIGHER amperage, than lower!! Charger will adapte it to phone specifics...A lower amperage will reduce your battery capacity in long time.
I once connected my Z5C to an old 500mA charger (caught the wrong cable) and kept using it a bit (screen on, etc.) and it gave me a nag screen that said that the charger is not suitable because apparently the battery drain from usage was more than what trickled back in.
However, if left alone even a 500mA charger should eventually charge the phone, taking much longer though.
Generally, with chargers, you need to get the voltage right. If the Amperage is higher that what the OEM charger is it does not matter. The electronics in the device limit the charge to what the device can handle. The Amperage on the charger is the max it can deliver. In other words, the charger does not pump 2.5A into the phone forcefully, the phone just nibbles whatever it can take (say 1,5A).

Any reliable source for that? The charging will be slower - yes, but I seriously doubt, that this has negative long-term effects on the capacity.

I think you need a 2A charger to be sure with the Z5c. Most of my older chargers take hours to charge it, and the car USB port (Nissan Qashqai 2015) barely charges it at all.
The UCH20 that came with the phone, takes 2 hours 15 mins to charge the phone fully. I got a quick charger which takes around 1 hour and 10 mins at max
Wow, really?
It is basic electronics. The voltage must be the exact one. Amperage is what the device draws , therefore the charger must be capable to provide a minimum not a maximum.
I repeat, it is basic electronics!
Now a more pertinent question :
What are the voltages for quick charge ? Does anyone know?
If someone has a original charger with quick charge can you please state what voltages are written on it?
Should be 2 or 3 voltages with lowest 5V
Edit : Found myself the info on Sony UK website of a Sony charger.

I also want a source for that... It's the first time in my life i hear it's the opposite... and i have been charging this phone with 1 amp or 500mA (with pc usb) for the past 4 years, battery is still fine. Only used a 1.5A charger a few times.
On the other hand, my sisters z5 had a swollen battery a year ago, she always used quick chargers...

Can I charge Xiaomi Note 10 Lite with a standard Samsung charger? Following are the specifications of chargers
Xiaomi Note 10 Lite came with 30w Fast Charger, following is whats written on the charger:
Output 5.0V=3.0A 15.0W/9.0V=3.0A 27.0W/12.0V=2.25A 27.0W/20.0V=1.35A 27.0W/10.0V=3.0A Max 30.0W Max
I want to use the following Samsung charger:
Output 5.0V=1.55A
I don't need fast charging and I am planning on keeping this phone for a longer period of time thus want to use a standard charger to save the battery.
Kindly if anyone has technical knowledge about these readings please advise me whether I can use the above standard charger without damaging the battery if not what standard charger should I buy for my phone?

Thank you but I asked the opposite, I want to charge the fast charging phone with a standard charger. The question was whether my specific charger with 5.0V = 1.55A be safe for my phone battery.
Also to add: the reason I mentioned the Volts and Amperage details is because I don't have much knowledge about it. I remember using a different charger (on laptop) with only slight differences and it caused the battery to bloat. So I need to be sure this Samsung charger won't harm Xiaomi's battery lol
Update: I have been charging 'Mi Note 10 lite' with Samsung Standard Charger (1.55A 5V) but the charger is getting too... hot, not sure whether its affecting battery life (battery is not getting hot) though.

Yes you can use any charger.
1.55A Charger gets hot because mi note 10 lite can support up to 30w so it get all the "juice" of this weak charger..
Technicaly the battery life will be even better with slower chargings.. but xiaomi batteries are very good in my experience and everything official (like 30w charging) will not harm the battery.

- Are you sure this charger getting very hot is not of any concern and will not hurt the note 10 lite battery?
- Also is this dangerous for the charger? It doesn't get hot with the Samsung pone it came up with?
- I am worried because in the past one of my laptop's battery bloated because I used a charger with 19V instead of 19.5V. it shouldn't hurt the battery by some experts but I guess it did in my case probably because battery was inside laptop all the time while I was using AC power, although laptop had a feature to disconnect battery when fully charged but in my case battery still got bloated.

volts matter.. you can damage a device and its battery with more volts than it supports.. about amps , the device will get as much as it can.. for example if u plug a 5volt10 amp on mi note 10 lite it will get 5 volt and 3 amps, and the charger will not get hot
mi note 10 lite can handle from 5 to 20 volt.
The only concern is about the charger because it give all the power it have.. but i dont think samsung charger will blow up they got all protections.. your phone gets as much as the charger can give (5v 1.55amp) but i suggest you buy a stronger charger so it can charge cooler

Less volts can't harm.. Laptop batteries are fragile and they die after 2-3 years.. To live longer you have to remove it from laptop when you are not using it (the battery if charger is plugged)
+1 TO ABOVE, won't be issues. Worst case scenario charger may die, not the phone battery.
