charger question????

is there a difference between the S2 & the Skyrocket charger & the note charger ? i noticed that my phone charging faster when using the usb that came with the note more than the one that came with my old skyrocket ? or is it just in my head ? i used both chargers & notice the one that was in the box with the note charging it much faster ?

[Q] Galaxy Mega 6.3 EXTREMELY slow charging.

My wife has a 3 month old Galaxy Mega 6.3 and it will not charge correctly. It will not change when it's on enough to keep it on. Last night I had her charge it while it was off and after 12 hours it was only at 48%. We have tried new chargers, new cords, taking the battery out for a while, nothing is working. Any ideas? It's completely stock, no root.
Hi .. make sure that your chargers output power is 2.0A don't use chargers with 1.0A or 0.7A output or it will charge slowly .. and try to use a short cable ..shorter is faster .. If this didn't help maybe the problem is with the battery it self buy a new one

Yeah, we used an oem charger and cable and a charger that puts out 5v and all the same charge rate
I think 5v is too much & dangerous for the phone maybe it'll ruin your battery

Hi..the original charger for the mega 6.3 is 5v with a 2.0A charging rate, can you test another battery from a friend to see if it is the battery.
I literally have never seen anyone with a mega besides her lol. My next plan was a new battery, but I didn't think a 3 month old phone should need one yet.

Maybe go to your carrier were you got the phone and explain what has happened and maybe they can give you a new battery or if it is a hardware problem..they can maybe give you a new phone.

She bought it outright unlocked, so I guess we would have to go right to Samsung?

Forsure then try samsung then as the battery should not be hosed yet unless it was a half dud to begin with. .

Hello SumCanadianGuy
To be sure to get fast charge with most Samsung smartphones, you need an original Samsung charger AND a fully connected (4 wire) USB cable.
Charger outputs 5.3 to 5.7V and pin 2 and pin 3 (data pins) are shortened together inside the charger to indicate the phone that he can draw fast charge current.
All my original Samsung wall chargers are rated only 1A. It doesn't mean that they can't output more current for a short time. I get fast charge every time.
If either your charger isn't an original with pins 2 & 3 shortened, or your cable has no data connections, you won't ever get fast charge. By example, if you try to use a powerful 2A or more iPad charger with your Mega, you won't get fast charge, just because the other world doesn't conform to USB
If you can, try an original Samsung wall charger with an original Samsung usb to micro usb cable.
Hope this helps
I have same problem with my Samsubg Galaxy Mega 6.3
I tried everything (change battery, cable, charger) but nothing help.
Charging is slow but during all night it could charge to almoat 100%
It only could be hardware failure...
If you want to see power of charging install app Galaxy Charging Current Lite.
Power of charging should be 1900 mA and I could get only 300 mA...

Redmi note 4 causing chargers to explode

Hi guys, I'm just wondering did anyone else had this problem. My Redmi note 4MTK already killed 3 chargers in a month (NOTE: The phone it self is only a month old. Bought at 3rd of April) And its not bad chargers or anything I used 2x LG G2,3,4 1.8a - 5v chargers and one 1a-5v charger.
I got scared from this fact of it killing chargers at this rate. So i gave it to the service center to get fixed.
But would be nice to know if anyone else having / had this problem and might know how to fix it!
Regards,

Sounds like a faulty unit that should be replaced or fixed by official means before it does some real damage. I mainly use mine will the charger it comes with, which is always recommended. I have used it with other different chargers but not had any issues.

The redmi note 4 manual states that it uses a 5V 2 Amp charger, also stated on the page http://www.mi.com/in/note4/specs/. If the charger cant give the current needed, it can burn the internal tracks of the charger, burn the internal components of the charger, or in case it can hold then it would drop the output voltage, so there are several cases of why a 1 amp charger can get damaged.

Well i'm pretty sure that phone has a module that recognize the output of the charger and sets the voltage as needed. So it shouldn't just keep any charger at 5v-2a

Yea i already sent it to the service center, It should get back to my hands hopefully in a week or two.
Avoid using those 1amp and cheap charger, they will get hot and cause unwanted problem, also if both the charger and the phone'battery got hot then avoid using that charger.
I have Redmi Note 4X. I use two charger that i trust: Aukey PA-T9 and RAVPower RP-PC017. Never had a problem with these two, as of the original mi charger i just kept it the the box.

The phone didn't come with the original charger, They gave me an replacement one. Which already exploded. And in this situation it doesn't matter original or 3rd party. There are better chargers then Original like Anker's , Tronsmart's etc.
Okay got the phone back, Seems to run more stable in the mean the charger doesn't get as hot as it was before. I'll try updating in the next few days if it does any more problems!

Redmi Note 8 - 18w charger

I got 5v 2a charger (10w) with my phone. I see that it supports 18w. Does it mean that it supports Qualcomm quick charge 3.0? Did you guys got normal charger or fast one?
Sent from my Redmi Note 8 using Tapatalk
In my China model, I got the 18W Quick Charge 3 charger. I might've seen somewhere which says it supports QC4 but it's still 18W
With my Indian model, 18W fast charger is provided which outputs : 5v=3A/9V=2A/12V=1.5A
I also got 10w charger. It does't support 18w, qc3 charging so you have to separately buy 18w qc3 charger.
I have the global version and I only got the 10W charger
Where can u see that , got a MDY-10-EF with mine.

It supports 18w fast charger but Xiaomi provided the 18w charger in the box only on Indian varient, but you can always buy the 18w charger online & use that with your phone...
Which 18w charger?
Which 18w charger is recommended? I have global version and 18w charger was not in box.

Anyone could suggest the link for purchase of 18W charger
Newest compatible 18W QC 3.0 Charger models are:
MDY-10-EF (EU)
MDY-10-EC (US)
5V-3A/9V-2A/12V-1.5A

Hi guys, I use an original Xiaomi 30w I do not know if it is recommended, it is very fast it takes between 60/70 min 10/100%
I would just say that unless you really need the faster charge, it's probably better for the battery to charge it slower. General suggestion for li-ion batteries though I suppose you can't be sure for this particular case. Maybe 1.8x higher current has no significant effect on battery life.
Hello what is the UK version of the MDY-10-EF charger called ?
Thanks for the link. It's around 6$ in my country locally.
quik charger
hello everyone. can i charge my note8 with a charger.

i wonder if 18W charger is good enough for long lige of the battery life.
i am very skeptical about charging the phone with 18W battery charger,
i am afraid that this charger could harm the life of the battery, so i more in the side that says, i will stay with the 10W typical charger.
Does anybody agree with that?

Agree.
18W charger only make the battery getting more heat, which is bad for battery.
I only use 18W charger if I'm in a rush.
Now I'm thinking to get myself a Blackshark funcooler and see if it able to reduce battery temperature while on fast charging.
