please forgive for the bad english.
im really skeptical that the samsung adaptive fast charger could damage my battery in the long run,
so i brought this phone charger and it says rapid charge and havent try it. i just want to make sure that 1a charger can do rapid charge or is only a gimmick?
i just want using normal 1a charger. thanks
Your AC wall adaptor is OK. You have correct values: output 5V-1A, the same as iPhone AC adaptor. I use original iPhone AC adaptor because I don't want to overheat the battery.

You should charge your battery when it reaches at least 10% . It's not recommended to discharge all the battery.
Hi,
Question for the redmi note 2 users.
What charger do you use to charge your phone?
When i used a normal usb wall charger that I used for my HTC the charging was very slow.
Switched it to the original charger that came and it was a lot faster.
Why does it take forever to charge on a normal charger?
Also what do you guys do if youw ant to charge throughout the day via a PC and when travelling in car charger?
Am i missing something?
Because the original charger can provide up to 2A of power. Just check the output spec on the charger usually it show the voltage and amp like this: 5V = 2000ma.
USB 2.0 can provide up to 0.5A
USB Fast Charge on some laptop can provide up to 1.2A (CMIIW)
All charger have the printed output spec.

I connected a new samsung fast charger and a message immedietely came up saying too much power overheating.
So basically I just need a charger that has an output of 2A?

Yea, Redmi note 2 doesn't support quick charge according to this nice thread about redmi note 2 charging, lots of great info there.
What I Thought Im Gonna Buy Redmi Note 2..
Sent from my GT-I9082 using XDA Forums
I use this charger with latest smiui in rn2 prime works very good i watch stream with 80% brightness and charge from 20 to 100% ~ 1 hour while watching

I need one for the UK.
Can someone send me a link for one to buy.
Also if you want to charge in the car do I havw to buy a car charger that supports 2A?
I assume same goes for PC?
So higher the Ampere number from a charger so faster it load ,BUT to high can damage the Battery so you are good with 2A or 2.1A think it also gives for the UK cause its only thing of voltage change

This is what I don;t understand the samsung fast charger is 2A isnt it? " It outputs 2A for ultra fast charging, so your S5 will be fully charged in no time."
Has anyone from the UK replaced the 2pin charging plug with a 3pin plug that maintains the quick charge if so which one did you buy ?
I use PC USB 2.0.
I don't care about how fast it charges.
For me the slower the better.

Have u measure the ampere in? It's fast I think...
As far as I know the charger that comes with the phone is QC3 with a maximum output of 18 watts. So how is it possible to have the phone charging at 31.5 watts based on these numbers shown while charging? 2.625A×12V is 31.5 watts.
the charger should have 18 watts output. So it doesn't make sense. Are these values correct or is it showing wrong charging data??
please help me understand what's going on and how could this make sense.
I'm using the latest Nitrogen OS stable build with the kernel that's coming together with the ROM, charger is the one supplied with the phone.
it uses 5v not 12

Not true. The stock charger has three different modes 5V with 2.5A (12.5watts) / 9V with 2A (18 watts) / 12v with 1.5A (18watts) see the image below.

I'm usually charging with 3000-3320 mah
The other thing that caught my attention is that the Amperage and Voltage stay constant and it doesn't get lower after the battery 80-90% charged... this is very unusual as the chargers normally start reducing the Amperage and Voltage at that point, but not in this case...

That's even more confusing to be honest!....with how many Volts? is it with the original charger?
I don't understand how can the charger perform much more than the rated values that is written on it, and if it can then why is it not advertised as a 30+ watts charger?!
Pretty sure the voltage/current sent by the charger gets converted to 5V xxxxmA by the charge controller or the charger sends 5V at different currents.
I increased my poco fast charge current limit to around 3000+mA from the 2800mA default which already shows that it probably charges on 5V.
Power meter shows 18-19W and phone shows around 3000mA. Makes it pretty obvious that the phone is being charged with 5V.
That's only my understanding it can be true or false.

Yes, original charger. Just flash extreme kernel with crystals magisk mode and you will have the same. It's safe.
As far as i know Mi A3 supports fast charging but my Mi A3 only shows rapidly charging even when connected to a fast charger ? Is it just my unit ?

It supports 18w quick charge 3.0.
So preferably use a quick charge 3.0 charging brick
I have tried 18 watt and 33 watt as well but still rapidly charging

Cannot understand your English, Mate
If you are using fast chargers, of course it will show fast charging
This battery charges very quick, even on a 10W=5V x 2A
I use the laptop USB and that charges quick also
Does anyone know if its safe to trickle charge your phone?

Download an app like ampere from the playstore and check the charging values with the different chargers. It will more than likely say rapidly charging for anything above 5v 2a charging which is quick charge 2.0 but this device also supports quick charge 3.0

If it's 9v then yes. If it's charging 5v and 2a then its not fast charging like it should.
Check the voltage also.
Basic maths; to get Watts (w) multiple the current (amps) x voltage (v).
So if it is charging at 1.9a like you say it should have a voltage ~9v

Then i guess it was charging fast, thanks man
what values did you get on the 33W, is it advisable to overcook your battery?
Btw, have not really pushed this battery yet, charging be 40-80 %

It doesn't work like that. Your device has protection built in to avoid overcharging and too much current from frying everything. The max your device will charge is 18w and no more
I don't yet have a 45 watt charger, so I connected the 25 watt charger from my S20. It says it will take 2 hrs to charge from 15% to Full.
My S20 would charge a lot faster than that. Is this normal?
I guess.
pixel 18W charger is 2h20.
iphone 5w is 5h15
LG 10w near 3h
I might get a faster one, I have the 20W oneplus one, but it wont work on the samsung... dash charging tech not compatible

Not sure if the S20 charger uses PPS charging protocol that S23U "requires" but 2 hours for 85% sound fine if it's not charging at 25 watts.

Thanks. My S20 with that charger would charge 85% a whole lot faster than 2 hrs.
45 watt charger should arrive tomorrow. Hopefully, it will go faster.

Yes, but as I mentioned, S23U requires PPS protocol to charge at the "advertised" speed. Just because the charger is 25W, it doesn't mean it will charge at 25W if it's missing the required protocol. Hence why I wrote I'm not sure if S20 supports the same PPS as S23U uses. In order to get 45W charging speed on S23U the charger needs to be PPS and the cable needs to be rated at least at 5 Amps.

That's what should be coming tomorrow from Amazon: Anker 313 charger and 543 cable.
Why Samsung doesn't include these with the S23 is a shame!

Well, some OEMs don't include a charger with their Flagships nowadays. Samsung isn't the only one.
That seems a little slow.
Make sure fast charging is on in settings. As you plug your charger in, it should say that it's Super Fast Charging
If it doesn't, try a different cable
If that doesn't work, go for a different charger
My phone keeps saying moisture detected, when there isn't, it's fked up, some chargers work, most dont
when you want to start charging your phone,make sure phone battery temperature is normal.
if you use continuously then charge it,charging speed is lower.
don't depend on status SFC or SFC 2.0.
you need watt meter cable or watt meter to know actually the real time charging speed.
if very hot,from 45 watt down to 15 watt charging (SFC 2.0)
if you want to charge from 10 to 100 in 1 hours use 45 watt charger,you need a cooler room temperature.
or you need a cooler at the back of the phone in 33 degree celcius room temperature.
if you wat to charge wireless 15 watt,it is the same.
battery temperature can make it slower charging.
status fast wireless charging is not the benchmark for charging speed.
SFC 2.0 is the same ,not the benchmark for charging speed.
you need a watt meter cable to know the real charging situation.
My S20 charger initially shows SFC as active when I plug it in but then it drops down to normal charging. Looks like I am not the only one with this issue so guess I will be buying a new brick.
Anyone got a good suggestion on which ones to get? In addition any good 12v car chargers that support it too?

The Anker 313 charger and the Anker 543 cable work for me.
I've had old HTC and Motorola phones from years gone by that took ages to charge. When I got the opportunity and the cash to buy my Samsung, I made sure I got a charger and cable that could super fast charge. From less than 10% to 85% capacity in just a few minutes. Wow.
