No time difference with quick charging - Samsung Galaxy S7 Edge Questions and Answers

I noticed something strange the other day. I plugged my phone in to my Anker regular multi-port charger and the phone said regular charging 1h 15m to full charge. I unplugged and plugged it in to the Samsung quick charger and it said quick charging 1h 5m to full charge.
Is that correct? I was expecting quick charge to be way faster than regular charging.
(Note: I did not actually time the charge though to see actual duration)

I noticed the same. Only a minor difference of 5 to 10 minutes.
But don't know if this is normal, it's my first phone with quick charge.

What was the percentage of charge when you started?
Quick charge works fastest the lower the charge on the battery. The closer to full it gets, the quick charge slows down to avoid overheating the battery.

You SHOULD have timed it...I saw on mine that the time is adjusted several times and the original estimate is WAY off (in a case like yours by 15-20min LOWER).
I personally saw a difference (significant) between fast charging and normal, despite having a "normal" 2A charger vs the 9v Original Samsung.
Moreover, I measured with a multimeter (the cheapo ones from eBay, pass-through) and the current and voltage are as expected...9v/1.7A for the fast charger. Hell, even fast wireless charging works.
Bottom line: do a full test.

Long time to charge ?

My Galaxy S, takes far too long for charge completely ؟
Today was the battery level of 19%, Connect the device charger, and after 5 hours and her grandmother, reached 93%
also the phone became very hot
Yes, I am also wondering about that. It takes about 6 hours to get from 5% to 100%. It is fine for me, since I charge the battery in the night, but sometimes there are situations where you want to get your phone charged quickly.
My previous iPhone 3G took about 1,5-2 hrs for complete charging.
I can't offer any advice as to why, but my phone charges from 30% to full in about 2 hours if I use the mains charger, but takes about 3-4 hours if I plug it into the computer USB port. The other thing, my phone doesn't get hot, only slightly warm.
I thought the same when I first got the phone.Have owned an iPhone for the last 3 years and that chrged up pretty quickly using the USB charger, in fact the Wall Charger is still sealed,never used.
But using the wall charger with the SGS really makes a difference.I would say under two hours from empty to full.

the usb port on a computer can only deliver i think 0.25amps where as a typical wall charger can do 1-2amps which is alot more. There it always charges quicker with a wall-plug-charger.
Sorry, i am from denmark, therefore my native language is not english
mine charges from 10% to 100% in arround 3 hours using the original charger...
I had the same problem initially, just do a few full battery cycles (2-3) and it should go away. If not, it may be faulty - how's the battery life?

Are you using USB or AC charger?
AC Charger gives you shorter charging time because of the higher amp input.
my SGS takes around 2 hrs from less than 10% battery in balance to full charge via AC charger.
The stock wall plug charger rated only 700miliamp, if you need fast charging you need to get a charger rated min 1amp, I use my old n97 charger to charge sgs, take about 2hr fr.black out condition, the charger rated 1.2amp output

Ampere rating is a max spec, the phone will pull as much as it needs. So you gain nothing from using a higher rated charger.

Today i got this message
" bttray temperature too high or low "

Nexus 10 taking more than a day to charge!!

Like the title says, my dad just bought a Nexus 10 and when he was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. Is it a defective unit? I know about the Pogo charger, but I'm sure he'd rather not spend $25 on it just to find out it doesn't work.
Any suggestions or ways to fix this?
Thanks.
edit: To make things even sound worse, it only charged 2% in 1 hour and 30 minutes.

All I know is that on mine takes about 9 hours to charge with the original charger. The first time I've charged it from 16% with my Galaxy SIII cable, and it took over 14 hours.
That does seem long. I have the pogo charger and it does charge faster.
Before you buy the pogo, are you using the chargers that came with the N10? When I charge my N10 from a laptop/PC, it does charge slowly. So make sure you're charging with the correct voltage/amps.
Good luck!
I'm having a similar issue since the OTA update to 4.4.2.
I'll try changing USB cables, but I'm not optimistic. I'm tempted to try a factory reset if a different cord doesn't work.

With Wifi on, NFC off, Location set to device only, bluetooth off, screen off, using my Pogo cable I get about 22% charge per hour so from 0% to 85% is 4 hours. Whilst on Pogo if I turn brightness to full and sound full then charge is held roughly flat. I moved to Pogo from the supplied cable as when watching stuff even when connected it was discharging, so now I'm never really out of power unless I stay unplugged a long time (about 6 hours unplugged max on low brightness)

This situation happens when the tablet isn't even on, so certain settings being enabled are not the issue.
And for more info, he is using the charger that came with the tablet, so we've just decided that we'll just send it back and get a new one because the battery is obviously defective.

Have you tried a different cable/charger? AN hour to charge from 20% to 50%? Sounds about right to me. I always switch mine off when charging, I can live without when it' off. :good:

I think clearly a human error in the word chosen explains it.
Instead of "...was charging it from 20%, it's taken more than an hour to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable."
it would make more sense if written "....was charging it from 20%, it's taken more than a day to charge to 50%. With that logic, the battery is only charging 30% a day, which means it would take 3-4 days from 0%-100%, and that simply is unacceptable. "
.... then the later post of its a dud and its been replaced makes sense....

Ahh, I see. Good call in getting it replaced. I hope you have a better experience.
here are a few points
1) the AC USB come with N10 charge up to 2A.
2) the mini USB limit to about 1A
3) if you use other mini charger, that 1A is even smaller.
4) N10 battery is HUGE comparing to all tablet out there. It will take a long time to charge
Solution: get the pogo charging cable that cost $25 (very expensive and can only use for charging), that will fully charge 2A to your tablet which should reduce the time to less than 4hrs given no other power hog apps running at the same time. It will charge slower if that power hog app running too. You can tell by how warm/hot your tablet gets when running such app.
btw, go look at the disassemble of the N10. That battle makeup most of the tablet. LOL

Agree, BUT once you get >85% the rate of charge intake drops. I can get to 85% in 3.9 hours using Pogo cable, but that last 85%-100% is slower. My battery meter sees one kink 85-90 another 90-95 and a slow crawl 95-100. As the battery is not taking up 2A >85%, all chargers, all cables, will largely take the same 85%-100% but the Pogo cable with 2A input will get you to 85% quicker.
I have moved to a dual 2.1A output PSU.

I know you revised the post but just looked at the link to the PSU you mentioned.
Note that $10 one is dual USB socket but only 2.4A total meaning if it is charging the N10 taking 2A it can only offer 0.4A to something else meaning that other thing can only be something like a phone. More importantly is the opposite if you connect a powerpack USB battery which takes say 1.5A or 2A then your Pogo cable cannot deliver its full capability.
The PSU I mentioned earlier is dual 2.1A both concurrently meaning it can charge the N10 and something else also power-hungry like charging a 2A input or 1.5A input USB battery.
There are PSUs out there which can do 4 lots of 2A concurrent, I didn't get one as they were getting chunky and personally prefer two PSUs, a 2x2A + 1A for total 5A which does my N10, my USB battery (2+2) and my phone (1) concurrently taking two power sockets.
Check the details of specifications of these devices, PSUs and batteries vary wildly.

How well does adaptive fast charging for you?

Any one actually time how fast their note 4 charges for them? Mine didnt seem to charge any faster than my GS4 the last few days so I finally set a timer, and it charged 50% in just over an hour and a half. Way off what samsung claimed, considering this was supposed to take only 30 minutes...and yes I have fast charging enabled and am using the fast charging adapter.
In 20 minutes charged about 33%. I am happy, cause fast charging working very well. From 25% to 95 % in 60 minutes.

I've done measurements this morning after getting my Note 4 last night.
I agree. I've found little difference between fast charging, and normal at the levels i was measuring.
Perhaps it works faster between 0 and 50%, which seems to be the stats Samsung always quoted. If there is any kind of intelligence circutry going on, it must be varying the amount of ampage being drawn from the charger.
I've found the amps drawn to be VERY low as compared with the S5. Obviously the voltage is the main thing changing with Samsung's "fast Charging" plug.
For example changing from 90% to 100% I found:
USB 2 lead supplied with phone + normal plug = 23mins 31 seconds
USB 2 lead supplied with phone + fast charging plug supplied by Samsung = 23 mins dead.
31 seconds difference is hardly stallar!
Yes you can say it depends on what apps were consuming resource in the background, but it was just standard apps synching etc.
Screen was off the entire time, and nothing processor intensive was actively running.
But I did notice something interesting:
If watts = amps x volts it might explain why the phone isn't charging that fast at the 90% level.
Note 4:
With anker 40w 5-port charge (capable of outpitting 2.4 amps per port, the typical draw was between 300 and 450 ma
With Samsung fast charger it was drawing between 250 and 350ma.
Obviously I'm not counting voltage, which will definitely play a part in the overall wattage. But there has to be some kind of intelligence here controlling it as it's not steady.
S5:
Anker 5-port: 1200ma steady
Fast charger (not compatable of course): 1200ma Steady
Which is also intereting seeing as the max output is 1800ma, so the phone still isnt drawing the max it could do.
Might try draining the Note 4 down even more, and seeing if it does up the draw when the battery is nearing empty
I was very impressed with the charging.
The ultimate test for me was when I was playing a fairly graphics hungry game whilst being connected to the fast charger. It continued to charge the phone up to 100% from 30% in around 40 minutes whilst playing.
I believe the best way to ensure the results are comparable is to make sure the phone is completely powered down and the battery has had a handful of recharge cycles first.
Anyhow, I am impressed with the charging and the battery consumption of my Note 4 to date
.
Impressive. Considering you were using a lot of screen and processing power. Sounds like a wait and see is in order, see how it pans out.
Battery life doesn't seem bad for what I have used, not but much better than I had on the S5. In time I expect things to improve though.
With me fast charging work very well
30 mins then 50% when playing some small game and surfing web
Sent from my SM-N910L using XDA Free mobile app
I went from 21% to 75% in about 40 minutes the other day (was monitoring), but my device was on and I had used it a few times in between that time... fast charging is really meant to be used when your device is OFF - that's where you'll get the most benefit.
Mine works fine. Remember it works while screen is off or phone powered down. Also from 0-50 only. Beyond that and it will use 5v to charge instead of the 9v. That's why Fast Charging will only work with the charger it came with.

Are you still having the same issue?
Im charging my phone for the first time and i dont find the fast charging works well with me. Its been an hour already and my battery is still at 30%. I also turn off my phone to make sure i get the 30mins 50% but no luck. Should fast charging kicks in after several recharge cycle?
Remember, it's called adaptive fast charging so it's charging rate varies depending on variables such as temperature, etc.
I went from 20% to 96% in about 60-90 minutes today. Not too bad.
I don't plan on using fast charging much to test, but it's my first few days with the phone and I've been stress testing it to see how battery life is.
90mins for me from 1% to 100%.
no problem at all. been charging from 0 to 100% at exactly 60mins
Impressed with mine used to have a spare battery but not anymore as the beast can really fast.
Must use included charger and CABLE
I found that for fast charging to work you must use the cable and charger that shipped with the Note 4.
hey and im sorry to dig this thread out again, but wondering if another tried fast charging with third party battery, I bought a ravpower note 4 battery off amazon and charged it with my note 4 adapter and I went from 10% to 50% in about 50 minutes, im sure its not fast enough.
note 4 adaptive fast charging
The phone has a chip and the charger has a chip it is this that allows the phone to charge at 9v only between 0 to 50. It's easy for people to be unimpressed because Samsung typically charge quickly. I tried a LG g3 for a few days and it charged ridiculously slow compared to a Samsung if it is taking an hr and a half to charge your phone halfway I would consider using your warranty for a new device or battery

is this correct?
It will only do fast charging below 50%?
What if it starts at 45% - will it stop when it gets to 50%?
I'm finding that Adaptive Fast Charging (AFC) only works (phone reads "fast charging") when the charge cycle is started while the phone's battery is almost dead. Now, "almost dead" means different things to different people, but my GS6 won't use AFC unless it's really low - I know it won't kick on/in circa 35%, but I don't know the precise level.
Here's some an interesting comment made on the awesome article at the link below:
"You should note though, that CABLES DO MATTER. Every el-cheapo ebay cable isn't supported for quick charging. They usually allow about 700mA to pass through. You need high quality cables that probably came with your smartphone in order for quick charging to work. I have done several tests with my Note 4 with several cables and an adapter that meters the output Amperage."
http://www.androidpolice.com/2015/0...-need-to-know-about-charging-your-smartphone/
Works great for me take about an hour and 40 mins from 4-fully charged.
I lost my charger so i cant help here
Been looking all over eBay & Amazon, but nothing...*sigh*

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V30 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Honestly I feel like this is not quick charge 3.0 even though the 835 processor and the device supports it. The charger that comes in the box is only 1.8amps output. Compare that to 2.0amps output with my Galaxy S7 charger and even 3.0amps output on my Nexus 6P charger. So it's not really more than the standard 1.5amp output of most cell phone chargers today and less output than other chargers that come with quick charge compatible phones.
Over all it takes around 1 hour and 20 minutes to charge it from 20% to 100% with the charger it comes with. Keep in mind that's if you're not using it while it charges. If you are using the phone while it charges on about 70% brightness, then about double that time to charger from 20% to 80%. I might try with the Nexus 6P 3.0amp charger later to see if it makes any difference.
So right now I give this only a 6 out of 10 for charging. So 3 stars.

Ran my phone down to 3%. Hooked it up to my QC 3.0 charger. Doing a timed 60 minute charge, I unplugged the phone at 82%
To be honest my last phone was a note 5 I just upgraded to v10 an I personally think that it charges just as fast, I put my my old samsumg fast charger to my USB-C an it registers at fast charging, charges while I play mmorpg, so GG I'm happy

I only tried it with a Samsung Galaxy S7 charger, which is
2.0 amp output instead of the stock V30 charger at 1.8amp output. So slightly more output.
It looks like no matter what charger you use above 1.8amp output, then the V30 is still going to only use 1.8amp charging rate. I think the phone is programed to limit it. Which is sad because I do not think it charges quite as fast as my S7 Edge.
When I plug the stock V30 charger with the phone at 5% it gives me a ETA of 1 hour 46 minutes. That seems awfully long time for quick charge 3.0 on a battery that is only 3300mah. It should be about 20-25 minutes LESS than that I think. According to LG it should be faster from their graphic at the release show of the V30. See attachment.
Although its possible a future software update could fix this though. So lets hope. I also might reach out to LG and ask them about this.

The little lightning bolt with a circle around it? Yes.
It also says "fast charging" in the notification instead of just normal "charging" when I plug in a regular charger.

Don't have a V30 right no, i've just compared the speed with the one seen on my G6, a 5-10% i have 1:50 for full charge without QC, for V30 you'll have to wait someone else...
quick charge feature is available only with original charger or by using power bank too ?
The Galaxy S7 adapter charges only at 9V/1.67A, for 15W of power.
The LG should come with a 9V/1.8A, for about 16W of power. Also, it may only quick charge with the screen off. It will drop to 5-10W with the screen on.
ummm...you should always check the voltage, not only the amps... (voltage multiplied by current equals power).
the best way to check is by using one of those USB thingies which measure V and A.
I'm pretty sure that v30 comes with qc 3.0 charger, so it definitely is a fast charger for that 3300mAh battery.
If I am not mistaken, the supplied charger is Quick Charge 3.0 compliant. But LG limited the charging to just 9V/1.8A, for total power of 16W.
The estimate on my v30+ at 7% battery is 1 hour and 43 min. In 15 min it charged 11% only.
Definitely slower than the galaxy note 4 I had previously.
The charger mine came with is 3amp and takes 45 min to fully charge

When I plug the stock V30 charger with the phone at 5% it gives me a ETA of 1 hour 46 minutes. That seems awfully long time for quick charge 3.0 on a battery that is only 3300mah. It should be about 20-25 minutes LESS than that I think. According to LG it should be faster from their graphic at the release show of the V30. See attachment.
Although its possible a future software update could fix this though. So lets hope. I also might reach out to LG and ask them about this.

Ok I'm not saying you're bullshittin', but 3A gives 3Ah per 1h, or 3000mAh in one hour and since the V30 has 3300mAh battery, it must take over an hour to fully charge (even if it charges max speed constantly 0-100%), so yeah you're bullshittin'.

The Galaxy S7 adapter charges only at 9V/1.67A, for 15W of power.
The LG should come with a 9V/1.8A, for about 16W of power. Also, it may only quick charge with the screen off. It will drop to 5-10W with the screen on.

If I am not mistaken, the supplied charger is Quick Charge 3.0 compliant. But LG limited the charging to just 9V/1.8A, for total power of 16W.

Yes! Very good point! What I have found is that it does charge pretty fast with the stock charger when you are NOT using the phone at all. Charges around 45% in 30 minutes from my testing. So pretty good!
However when I'm using my phone it takes about double the length of time. About an hour to get the same 45%. So I did a test to see what the heck was going on.
First I bought an Anker quick charge 3.0 18W adapter. So it is rated 2 watts higher than the stock LG charger. The Anker charger has output ratings of
3.6V-6.5V / 3A, 6.5V-9V / 2A, 9V-12V / 1.5A
I also bought a nice braided JSAUX cable rated up to 3Amps to make sure I am also using a cable that does not restrict the charge flow.
My results are about the same with that charger and cable despite it being rated 2 watts higher than stock LG charger. About 45% in 30 minutes when not using the phone and about 45% in 60 minutes when actively using the phone.
I also used an app to measure the charging current when not using the phone and when using the phone, and you are right. LG is for some reason limiting the Amps to only about 1.2A and 5V when using the phone, but then about 2.4A and 5V when not using the phone. I never saw the voltage go higher than about 5.1V. Assuming the app was accurately measuring the charge.
So I guess LG limits the charge when the phone is in use to keep the battery and phone from over heating while processor and display is working more? If so, it's obvious to me that they limit the charge while the phone is in use a good bit more than my 6P or S7 edge did. Hopefully with the upcoming Oreo update the charging rate is increased a little while the phone is in use.
When I had the phone, I measured with a USB meter. I was using a charger that's similar to your Anker, up to 18W.
With the phone or screen off, it charges at 9V/1.8A.
With the screen on, it charges at 5V/2A for 10W. But depending on what you're using the phone, eg. Watching videos or playing games, and your screen brightness, the effective charge is likely lower than 10W.
Since then, I've always developed the habit of not using my phone while charging.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Redmi Note 5 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
2 Hour With Stock Charger
I didn't completely check the ratings and time but stock charger DOES NOT fast charge this phone. as the Stock Charger isnt QC2.0 Supported. However this mobile does support QC2.0 but you'll have to test QC2.0 Charger 1st. Not all QC2.0 Chargers work on this mobile. Its a little picky. So go to a shop check QC2.0 Chargers on your mobile. when you get circle Sign on notification bar along side battery then it means that device is fast charging. if not then there will be no circle around the charging sign (Flash sign)
also idt this mobile supports QC3.0 but i dont have tools to check amps volts of charger.
Lenovo's original QC3.0 charger doesnt work on this phone. I've tested. but Motorola's QC3.0 Charger works fine.
my rn5 pro , takes apporx 3 hours to charge completely!
So far I'm a bit slow, a little bit more than 3 hours to completely charge the phone. Might have something to do with the cable.
My current charging setup:
- ANKER 5 port 40W
- a docomo USB cable
Planning to buy a proper 20AWG usb cable and a QC2.0 adapter.
I just bought a Letv charger which supported qc3.0 for about 4$ on taobao
I'm currently on the 9.5.11 build and it takes about 4-5 hours to completely charge the device using stock charger, And it took about 2-3 hours while on 9.2 build.
I wonder if the Mi QC 3.0 based charger would improve the situation for us?

Slow charge is a known bug in 9.5.11 build. Wait for an update or change ROM
13,2W for me
I recieved 9.2.13 update yesterday and have been noticing significant boost to charging speeds since then...yet to fully charge from 0 so can't comment on total time but as per Ampere, charging speeds are in range of 1500 to 1700 mah
1000 mA max with 5v 2amp and Work Normal Speed with Stock Charger
Approximately 2 hour for charge phone
I use the app Ampere (free in Playstore) to measure power input and with a normal charger (non QC) it shows up to 1600 mAh charging amount and from almost 0 to 100% it is taking 2,5 hours. One question: is there a way to tell if QuickCharge is active?
@Kusie
Look on your"s phone status bar. With normal charging there is thunder icon next to the battery. With QC active, thunder in in circle as far as I remember. Info about active QC should be also displayed in the bottom of your lockscreen
Sent from my flo using XDA Labs
Using my usb inline meter, i'm getting ~6.5v and ~2.2A, with a Tronsmart usb cable and QC 3.0 Truro charger, screen off and about 44% remaining on battery. Will try when the battery is lower some other time.
takes around 2hours to charge 100% using stock charger..
1h 30min with a Quick Charger from Anker.

Of Course it's true, why should I lie?
Turned off the Phone at 5% and charged it to 100%....

I have no idea why would you do that... But read reviews, no matter what kind of charger you use, this phone only supports qc 2.0 version. From 0 to 100, in 1 hour, you only get like 55%, and in the end it slows down even more, so yes, impossible to fully charge in 1.5h, TECHNICALLY IMPOSSIBLE. You are either lying, or mixed times and got confused. Judging by technical parameters, the best this phone can do should be around 2hours from 0 to 100.

I just posted above that I was able to get QC 3.0 charging rates. Approximately 2.2A (fluctuates +/- 0.1A) and 6.6v (fluctuates +/- 0.2v) using a QC 3.0 charger and Tronsmart cable. Measured using an inline meter, not software.
