Get the charger at the link below
http://www.amazon.com/Motorola-Vehi...Q9CA/ref=sr_1_1?ie=UTF8&qid=1334801727&sr=8-1
I got this to replace a cheapo one i had when i had my Droid X. With the old charger, I couldnt keep the screen on and use GPS and listen to music at the same time without the battery losing power. Basically the old charger acted like a battery extender lol.
This new charger charged my phone at least 3-4x faster...even while doing all the things listed above...WELL worth it

I have that exact same car charger. Just make sure that you get it from a reputable dealer... I got mine from one of the parties for a few bucks cheaper and they sent me counterfeits. I had to contact Amazon where Amazon gave me my money back and also sent out two OEM from an Amazon warehouse with free expedited shipping!

Quite a few of the cheaper car chargers simply do not have a point soldered on their boards, causing the phone to think it's charging from a 500mA USB port (like you'd find on a computer) and not go above that even if the charger does 1A/port.
I know even the belkin one has a forum topic somewhere regarding modifying it so that it'll always get detected as an AC power. I believe custom ROM's and kernels has a Fast Charge feature that can fix this too (ie force the device to detect the power as AC), I think.

I use the Motorola charger as well, and it works just fine... I had two lying around, one came with my Milestone and the other came with my Milestone Car Dock that I've bought separately...

Interesting, this is the model I had and I ALWAYS felt like my battery was draining while using the GPS+Music combo. Not a lot, a few percent over a couple hours, but it's not charging it or atleast keeping its current charge. I want the official Sammy card dock. SOMEONE JUST TAKE MY MONEY.

I believe you will be disappointed...
First, this Motorola charger is good up to 2A, while the original Galaxy Nexus Wall Charger is good up to 1A, and Galaxy Nexus recognizes it as AC Charging, meaning that phone is draining as much current to charge as it can...
Second, I do not believe that those pogo pins are good to move 1A, and I could bet the farm (if I had one ) that it won't go over 1A for sure, so, I do not believe that the official car dock will allow more current than what this Motorola charger is already providing...
But, anyway, I doubt that charger is the one to blame, and I will tell you why... Battery is rated 6.8W/h and it usually allows up to 4 hours of screen on time... So, quick math, phone in use, screen on, is draining 1,7W/h and USB charging (500mA x 5V) gives you 2,5W/h, AC charging gives you 5W/h....
Lets say that you get up to 3 hours screen time with GPS on... It still is 2,27W/h... Below 2,5W/h USB charging limit...
So what is going on? Probably battery is too hot charging and being discharged at the same time (and probably the phone is not able to use the battery like a no-break and get its power from USB, so, phone is getting juice from battery and battery from charger) and phone will stop charging to avoid battery damage/explosion due to high temperatures, and also, battery efficiency is lower when battery is hot (it will drain faster)...
My guess is that if phone is still draining with a charger, in this case, check if it is too hot, and if it is, try to move it so it is cooled by car A/C / vent... At least, with milestone, it helps a lot, since I still own my Milestone and its gps is leaps and bounds better than Galaxy Nexus GPS, I've never really used Galaxy Nexus to navigate (yes, my Milestone turned into a dedicated Google Maps GPS )

its very easy to mod any usb charger to turn it into a AC charger. what you need to do is connect the two data pins.

just connect pins 2 and 3 by solder, i've done this on a few car chargers and it works great always shows AC. i didnt modify the usb wire itself but opened up the charger and connect the solder points connected to the data lines, not sure if you can just mod the usb wire. i have 600mah car charger that i did this to, before it wasnt enough to charge the phone with google maps running now it can charge it very slowly.

Just a update,
i purchased the motorola charger and been working great for nearly a month till this couples of days.
the only way that charge is by holding and pushing up the micro port wile inserted in the phone.
i noticed that the charger micro plug does have clips on only one side ,the other side is flat.
does that mean is not a original charger???
thanx

I'm currently using this cables

generally can be had for about 3 bucks shipped. works fantastic - the phone reports as being plugged in and charges accordingly.

How long does your S 10.5 take to charge

Mine takes 6 hours to go from 10% to 100% using the included samsung charger and cable. That seems like a long time.

Mine takes 2 or 3 hours. 6 hour charge might are the chargers with slow charging. My dad has a slpw charger till he changed it. Have you tried changing chargers?

It's USB 2.0 so it's expected to be slow. The 3.0 port would have been bigger. Samsung sacrificed charging speed for aesthetic. To be the thinnest tablet they've ever made.

This is the first tablet for me and in effects.....too much slow on charges. Fortunately I use only at home. A part that....it's a bomb !!

Too long
I just bought a TAB S and using the included charger and cable it has taken 10 hours to go from 18% to 58%. The tab was turned off. TOO SLOW. Do I have a defective tab? Please let me know so I can return it.

one of my friend has this tablet. i got 2.5A charger. he also complained this issue to me. i gave him my charger and it charged to 100% in about 3 hours. now he would not return my charger.
DO IT ON YOUR OWN RISK! but i will recommend u guys to get the charger of say, Oppo find 7. or any ANDROID device charger which is more than 2A. it will be better. of course, better find samsung charger with more amperage.
again, DO IT ON YOUR OWN RISK, IM NOT RESPONSIBLE for anything! (just to clear my self)

Samsung Model EP-TA10JWE that the same as original one but it charge faster that the old one , I think Bcuz the original is old enough for me to buy new one

Mine charges exactly from 0 to 100 in 4 hours.

A full charge take around 5hrs.

with, I charge in 3,5h at pratically full charge possible (around 1800 maH max) since more than one year without problems (with original charger).
the original cable never goes more than 1000-1200 mah because it became rapidly too old.

That`s not a full charge 7900mah / 1800ma is 4.38hrs and it`s over 5hrs when you add the 20% charge inefficiency.
1750ma is the highest charging rate according to my usb power meter that i have seen with my 10.5"

Quick Charge

So those that have a G4 in hand does it have QC2.0?

It has QC2.0 as long as you have a QC2.0 charger. The phone itself came with a 1.8A charger.
Amazon has one for $10.99 if you're interested. Let me know if you want a link for the Aukey QC2.0 wall charger.

This AUKEY is NOT compatible with LG G4 Quick Charge 2.0 even thou the Charger is certified by Qualcomm or the one i have is faulty.
LG G4 Support QUICK CHARGE 2.0.

Personally I've ordered an iVoler Adaptive Fast Turbo Travel Charger from Amazon UK which states its a Quick Charge 2.0 18W Wall Charger Qualcomm Certified that supports the LG G4 - it should arrive tomorrow so I'll let you know what I find out

I'm using the Motorola turbo charger and it seems to be charging pretty slow. I've been charging it for about an hour now and my battery went from 15% to about 48%. With my Moto X for this same time frame I would normally be about close to 70% charged by now. Not sure if there's some kind of update I need for the G4 to charge faster

Well my iVoler arrived today - phone was at about 30% when I put it on charge - after approx 45mins it was back to 100%. PORTAPOW was reporting approx 6.5v and 1.8A rate of charge.

Quick charge problem?

Guys, just quick question. Today morning I plug my phone to the original charger (phone was totally discharged (switched off)) and after boot it said me "Quick Charging, fully charged after 3 hours". Bloody hell, is it any type of joke? I thought that quick charging feature is about quick charging, isn't it? Next problem which I have last time (the day before yesterday probably) was that phone told me "fully charged after 1 hour and 20 minutes" but it took almost 2 hours. I use original nexus charger.
Has anyone the some experience with this type of "fast" charging?
Thanks in advance.

My phone charges slowly only when i use it plugged in to the wall...Make sure the slow charge is a software issue and not a hardware,try to calibrate the battery and if it doesn't work try to flash the stock google images (do a backup before flashing),finally,send as a screenshot of your battery stats while charging to see how bad your device charging rates are!...

If your screen is on or the battery is warm, it will charge much slower.
I suggest you leave the screen turned off and let it charge, and check back in 30minutes to see if the charge time has updated to reflect a faster charging rate.

Should charge perfectly fine if you have the screen off and don't use it. I regularly go 15% to 90% in 60 minutes.

It's cause you started at near 40%. All fast charging has basically three levels that tapers from fastest to slowest. Basically in simplest terms it's 0-40% full fast charging, 40-80% regular charging, 80-100% slowest. There's actual numbers with mAh readings for exact details but no need for that. It does this for temperature control. It's also why a lot of fast charging tech advertise 0-80% times. That last 20%, especially 90-100%, is way slower than any other part. So to get the most of fast charging it's actually best to use your phone down to a low reading like 15-20%. As you can see, you end up wasting time trying to charge like you did compared to my screenshots. Essentially you're able to use you phone longer and yet be plugged in for a short period.

Mathematically that is correct, but for longer battery life expectancy (over time), they suggest you charge 50-90% even though it is less efficient in terms of amount of time spent charging.

So I tested charging for one hour starting at 40% and it actually did a little better than what you're getting. Went 40-93% in 60 minutes.
I still suggest starting around 15-20% though because as you can see, 60 minutes of uninterrupted charging gets you to 90% whether starting at 15% or 40%.

Guys, thanks for your effort. I will be trying to find the best way of charging. Even though energy efficient could by better in Google's Nexus I think. I have problem to stay charged 24 hour in a row. Maybe the reason is that I did just maybe 10 charging cycles and the battery is still to new and is still formatting, who knows.

Yeah if you check the battery life thread you'll see people getting various hours of battery usage. Personally, I'm always topping off when I get home from work for about 30 minutes or so (I always shower when I get home) and end with plugging in while sleeping.

in my experience, everytime I had trouble with fast charging (Zenfone and Nexus 5x) was a matter of faulty cable. try to replace your old one. in most cases, processors are kinda super sensitive about the "health" of the cable and won't let the magic happen it's happening to me in these days with my QC2.0 car adapter.

Which 3rd Party Charger

Hi,
i am just wondering, which Charger should i buy for the S21 Ultra, as i need more, i would buy them not from samsung. Do you have recommendations?

I have the wireless pad that was a freebie with the watch a while back - I'm hoping that will do the job in the day and I'll just use an old one for overnight charging - speed is not of the essence.

Ah cool.
Sometimes during the day i am happy to charge it quick fast, but mostly i also dont careabout the speed, especially overnight.

You can never go wrong with an anker charger but if you can buy from samsung i would recommend their 25w charger. Samsung recently reduced the price of the charger and if anything ever goes wrong with your phone samsung can no longer blame the charger.

I went with the 25W charger from Samsung. It is actually on discount.

i bought this 120w GaN Baseus and both charger and my S21 Ultra came today, i tested the charger with couple of outlets and cables but after couple second of "SUPER FAST CHARGIN" it reverts back to "Fast Charging" ,
its a shame cause i really loved the charger despite the noise it made and i wanted it for my future laptop too which supports 100w PD ,
i have to return it and get the normal one that samsung offering, samsung should've kept the chargers this year...
hope i didn't damaged my brand new phone by connecting and disconnecting it around 20 times

I have a 45W USB-C port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or long term longevity of the battery by purchasing Samsung's 25W charger?

You can get the maximum charging speed from the 45W Anker PowerPort. And the 18W charger would give you decent charging speed as well. When it comes to charging S21, there's no difference between the 45W Anker and Samsung's 25W charger. And I doubt there's much difference between the 18W and 25W charger.

Thank you. And it shouldn't cause any issues to the integrity/longevity of the battery?

No, it shouldn't. Reliable third-party chargers should just work fine as the original Samsung charger.

I do not know where he lives but here is a screenshot from the Canadian Samsung.ca site. I would think in the US it would have the same discount and be even cheaper.
Edit: Looking at his part number, I would guess he is in Canada too.

what about this BS Samsung Money by SoFi debit card?
"enjoy up to 30% off sitewide on .... Samsung.com"
do you really get a huge discount with this BS debit card ?

I had to buy another fast charger the other day because of a failing 25 watt brick or cable for my 10+; Fast charging is erratic.
The Samsung 25 brick/cable can be had for under $20.
It's known to work.
I nixed the 45 watt because it likely will decrease battery life and charges only marginally faster.
A working 25 watt brick charges at about 2% a minute which is fine. I go with 20-30% midrange charges so a 10-15 minute break is good.

I do not know where he lives but here is a screenshot from the Canadian Samsung.ca site. I would think in the US it would have the same discount and be even cheaper.
Edit: Looking at his part number, I would guess he is in Canada too.

According to the article below, only four of the chargers they tested charged the S21s at 25W. Two of the four were Samsung OEM chargers.

Fast charging gives me a headache as of late.
A fast charging mini horror tale...
My 10+ was fast charging normally until I slow charge it to 100% one night by accident.
The battery was probably around 85% of its original capacity at that time.
I've tried a new Samsung OEM 25w brick/cable, cleared system cache, toggled fast charging on/off 3X, hard reset, battery calibration, cleaned the C port throughly... everything except a factory reset.
Fast charging engages but usually only for 2-5 minutes, and sometimes the indicated current draw drops as low as 800 ma with only a 80% charge! WTF?
So... is it the battery, port* or a mobo failure?
It's battery replacement time but will that get it?
*the C port appears to connect normally; no charge or data interruption if pushed about.
Good, solid feel... grrrrrr

Just got a EP-TA800 charger and tried charging my S21 at 35% battery capacity and noticed it negotiated at 9V2A = 18W , I also checked this with wall plug meter. But on screen it shows its at super fast charging. So whats the range for 25W charging speed ?
