I've got an E5823 which should support Qualcomm® Quick Charge 2.0. (9V 2A)
I've bougt a Aukey PA-U28, which is Qualcomm certified.
Charging my phone with it is significantly faster, but here is the crux:
Drainage is at least twice as fast as normal, under these circumstances, quickcharge is complete bs for me.
Is someone else experiencing the same issues?
Edit: my phone also gets very hot during and after charging.
I don't think I have this issue.
I've been using the same Aukey charger for a few months and my battery it's really fine for the usage I give to the phone.
If I had to compare it with the stock one (used just the very first days) I'd say there is not difference in battery draining.
Now, regarding battery charging time. I don't know if QC is being used at the maximum level. I made a test last week to see how much time it takes to charge:
12:15 - 4%
13:15 - 79%
13:37 - 94%
14:00 - 100%
I'm not a quick charge expert, but I think we should ignore the last ten. Because from 90% to 100% i'm pretty sure QC does not exist, to prevent battery damage.
Considering this, do you think QC is working fine here? Or it's just using "1.5 or 2A" regular charge?
I've got the same aukey charger, it is probably about 25 minutes faster for a full charge. If I remember right it was 1hr50 aukey and,, 2hr15 sony

Well I bought the Galaxy S3 on the first day of the UK launch and depleted the battery to 0% then charged with the original 1 Amp charger from 0%. I had noticed that this takes a very very long time, around 8 hours. The battery life after charging however is substantial and very adequate.
On the second charge after depletion once again, I decided to use a Griffin 2.1 Amp charger which I had used to charge the hefty Galaxy note with. The Galaxy S3 charges at a much rapid rate and takes around 2-3 hours to reach 100% from 0%. However I have noticed that the battery life depletes a bit faster, Is this due to my imagination or is a 2.1 Amp charger not suitable for this phone as it was with the tablet-like Galaxy note.
Also note that I tried to charge my HTC one X with the 2.1 Amp charger and it charge very slowly, while the original HTC charger has a much lower ampage than 1 Amp
Hmm I have been using my galaxy s charger 0.5amp and it has been charging pretty slowly but seems to deplete faster.
I have been actively using for 50min on wifi now and 85% left. Which seems a bit quick for me. I will try charging with the standard 1amp tonight and see.
Now fast are you depleting at?
I measure my battery life by checking the screen on time just before the death of the charge which was 5 hours on the original charger, with the quick charger its 4 hours. My Galaxy note has no change in battery life weather you any ampere chargers. Also the general battery percentage seems to run low faster anyway on the galaxy s3 using the fast charger.

I shall try the standard 1 amp charger the next time my phone depletes

Just wondering, since the S2 had a limit of 650mA for charging, does this apply to the S3? You guys make it sound like it charges slow as well...
Galaxy s2 does charge very slow for me aswell. Compared to htc phones the Galaxy s 2 charges painfully slowly. Now I regularly use the 2 amp charger on my galaxy s3 and have seen a huge improvement in charging speeds. It charges at around 2% per minute and still lasts around 4 hours of screen time for a full charge.

I noticed that I can only charge fast using original charger. While charger with shorted usb data + & - (ie. htc 1A charger) will not activate fast charging.
You can verify by going into *#*#4636#*#*, Battery, using ori charger will show AC while HTC charger will show USB
I think samsung made some changes to the microUSB pinout

Thanx for the "shortcode". Where does one find those?
Also from reading about the MHL to HDMI cable from older devices not wotking, it does in fact seem that Samsung have changed the microUSB pinouts (although my Nokia 1.2A charger shows AC in that battery "menu").
Mine charges from about 10% to full in about two and a half hours, using the charger provided in the box.
My s2 came with a 0.7amp charger and took about 2.5 hours. My s3 came with a 1amp charger and takes about the same. Charges to 80% in no time and then slows down for the later part of the charge

A battery isn't like a fuel tank which you simply fill up through the hose until it's full.
Due to physical and chemical reasons, a nearly-full battery takes a lot longer to fill by a certain percent since it simply can't store the energy quickly enough.
Additionally, deep-discharged batteries often start with a slower charging speed (and then cranked up) to keep the battery from dying too soon and/or not being able to reach full capacity.
is the Nokia 1.2A charger ok to use with the samsung G3 as i got one of these spare and would prefer use it if so as the usb is way to short to reach from my desk up and around the back.
but the Nokia 1.2A charger lead is more than long enough
Just to check with all of you, i've been told that it is best not to charge your phone or any other handheld device IF the battery is not at a really low rate, at least not till your device actually prompts you to charge. They were saying that this would cause the battery life to be shortened. But at times, I need to make sure that i have enough battery to last me for a few more hours before i knock off from work, i would just charge the phone (battery at 25-30%) even before it prompts me to. Is it alright to do that often?
2ndly, at times when i stream videos on my phone for many hours, the battery would definitely drain fast and i would need to charge my phone at least 2-3 times a day. Is it alright for me to do that or am i "abusing" it? =X
Appreciate all your advises...Thanks in advance~
so any update on if using the nokia charger is ok with it being 200mah more than the standard 1A charger since it has longer lead.
or there is the 700mah samsung charger from my old S2

I don't know why this misconception still lives on; lithium ion batteries require no priming on first use. The WORST thing you can do with a li-ion battery is to fully deplete it before recharging. It is much better to top it off whenever possible; having said that leaving it turned on, on the charger once it is full is also not the best thing (though nowhere near as bad as depleting it fully).
I believe since this phone has a removable battery with external charger the best thing you can do is always charge your battery in the external charger and just switch out the battery when it gets to around 10%.
Nek0onna you should charge your phone whenever it's not full and you have a handy charger.

what about using different chargers though as i have said yet not answered yet,
i got a samsung s2 700mah charger and a nokia 1200mah charger which will work the best for the battery etc
the 1A included one the usb lead is to short for use behind a desk

Can anybody check what the max charge rate is on this device with a battery monitor app? I have handfuls of 1A and a couple 2.1A chargers. I'd really like to charge at twice the rate if possible but not all devices support such rapid charging (kernel limits and such). Just curious before I buy one Thanks!
Even if Samsung slipped up and allowed a 2A charge i'd never want to try it, because tablet and laptop batteries are rated and manufactured for a higher current charge/discharge and most phone batteries would heat and swell up and possibly explode.
my HP touchpad charges with a 1A charger and it would be nice to use that with my sgs3.
Can anybody please check what the max charge rate is on this device
So, I drained the battery until the phone turned off and connected it to the oem wallcharger, but i used a monitor to show voltage, current, amps and time. This showed a quite mysterious behavior of the charging process, which lead me to this thread. I'm hoping that someone can explain this.
First of, the phone charges at 9V when plugged in the wall - this is to archieve the so called fast charge. The current is ca. 1,6A. When the phone reaches 50 pct. or so, the current falls quite a bit and even further, as the battery is charged. When charged to aprox. 80 pct., the current is 0,3A +/- (still at 9V). Why does the current have to be so small? I mean, 0,3A is what my headset charges at.
Furthermore: When the phone said 50 pct. charged, my monitor showed that it had only gotten about 800 mA, which is quite weird due to the capacity being 2650 mA. I know that the phone measures the voltage over the battery, but still... It's weird, or?
When fully charged, the multimeter shows a total of 16xx amps... I'm confused.
I'm sorry for the bad english and sorry if this is the wrong forum.
Edit: The image is taken when the phone said 50 pct. charged. As shown, the current has already gone from 1,6A to 1,25A
It doesn't really surprise me to see that you noticed some weirds results when you tested the battery. I don't know much about the battery Hardware problems but I got weird problems with my battery as it skipping 4 percents (going down from 7 to 3%) and dropping really fast. I don't think your results are that mysterious as a lot of people have been complaining about their battery life and your data does confirm all the battery life issues.
I guess it is just the s6 so far. I havent had any issues but i also charge when i get down to 20%

About 90 minutes
Weird Mine takes 1hr 50m from 0 to 100%
Only 30 mins but lasts for 3 days of constant use afterwards.
I'm also surprised by these different delay...
I'm not using a quick charger and I'm able to charge my P9000 phone in 2h00/2h15.
I was waiting for a 30/45 min complete charge from 0% to 100% with a Pump Express + Charger.
I tried my phone on 2 Pump Express (not +) charger with a probe linked on the USB power lines and an Oscilloscope and it never change the power supply voltage....
It always stay at 5V.
I was thinking the phone will manage the voltage to accelerate the charging process, but nothing happened.
So, to have a complete view of the problem, I've ordered an original Elephone Quick Charger, and I'll check if there's any change about this subject.
But from my point of view, the Pump Express System is not working at all on the P9000 with the Aerom V4 or Stock ROM 20160608.
If other people have the same issue, please share it here to identify if it's a general bug or limited to some devices only.
20160608 kernel hace messed up fast charging. To me in aerom3 it takes about 70 mins from 0 to 100%
Fast charging still slow
I havent charged from 0% but based on charging times so far I reckon 1.5hrs would definitely get to 100%.
I use an Anker faster charger and Anker usb cable.
Last phone got fried with Elephone cable.
Hello, my Xiamoi Mi 9 is arriving end of next week and I am pretty hyped!
I am really not sure, if I do need these mentioned charging techniques. Apparently you can charge your phone from zero to 100 below one hour. Is it good to charge a phone very often and that fast? Doesn't it heavily influence the battery life? Shouldn't you just use a slow charger and charge it only up to 90%?

Well I don't think the charger influences battery lifespan, it's how you use the device that does
Most phone batteries are lithium ion batteries and honestly chargers (except fake ones) will not harm your battery regardless of charging speed, phones are built to handle them
If you continuously fast charge your battery, it will lower the lifespan of the battery over time. Unless you're planning to keep this phone for more than 4 years, it's not really that big of an issue. But charging speed does affect battery life.
What affects battery life is letting it go to 0% on Lithium. Just make sure you start recharging it around 10%-20% and you will make the battery last for a very long time.
Hi
Just bought a GT Neo 2 but didn't get the Realme 65W charger. I do have a Samsung EP-'T4510 USB-C Quick Charger 45W + USB-C Cable.
It's obviously not going to charge the phone as fast as an original 65W charger does but it's not charging as fast as I'd expect. Plugged it in earlier at 49% and it was at 91% 40 minutes later.
So what affects charging time?
Charging set up as follows:
1) Using extension lead
2) Using adapter to convert 2 pin EU charger to UK 3 pin
3) Samsung T4510 (45W) and the cable that came with the T4510
Do the extension lead or adapter affect charging time? Also does the cable affect it? Do fast chargers have to be used with a specific type of cable?
The charger/cable has to support the charging protocol of the phone or it will only slow charge.
Best to use a OEM brick/cable no longer than 3 feet.
Battery temperature needs to be high enough at beginning of the charging cycle for fast charging to engage. Minimum 72F, but 82-90F is best.
Fast charging may engage below 72F but Li plating becomes likely. Below about 55F fast charging will likely be disabled.
Above about 103F or about 80% capacity fast charging with be ramped down or disabled.
If screen is on, fast charging is disabled.
A battery fault will also disable it or cause erratic fast charging ie a battery failure.

Fast charging produces more heat therefore will reduce the lifespan somewhat.
On my heavily used Note 10+ I now replace the battery every year or so to help prevent a battery failure, routine maintenance.
The charging curve is controlled by the phone not the charger. The charging curve should be near identical if both bricks supple the required peak voltage/amps and the phone power controller can communicate with the brick.
Thank you kindly. Much appreciated.

You're welcome. Play with it to see how it works.
Start the charge at about the same temperature then time how long it takes to gain 1 or 2% without turning on the main display. Watch when it ramps down during the charge cycle. It will vary but I see 2%@minute sometimes a little faster at the peak fast charging rate on the N10+.
To extent battery life limit discharge to 30% and top charge to 80%. Li's like frequent midrange power cycling; it extents their totals full charge cycles many fold. A 40-67% usage range is near ideal. Limit the current draw; higher current usage stresses the battery more as does back to back discharge/recharge etc cycles with no rest period.
That's one reason it's just easier to replace the battery. When an Li reaches 80% of its original capacity it's considered degraded and has reached the end of its useful service life. It should be replaced. Degraded Li's are more likely to fail which can seriously damage the device.
Any battery swelling is a failure, replace immediately.

That's all very interesting. I have often read about the 30 - 80 range. I used to own a Huawei P9 and always charged to 100 and that battery didn't last more than 2 years. Last phone was an A70 and that'll be 3 years old in June. Started getting random reboots recently and a quick Google said that's most likely down to the beginning of a battery failure. So just got this GT Neo "as new". It was obviously sent back to the online store by original purchaser minus the charger (replaced with a 5V 2.1A charger. Store had no OEM charger listed on site for sale so I agreed to take a the EP-T4510 charger. While it's not ideal that I won't be getting the fast charge of the OEM charger, it's far from a major issue for me, as long as I'm not going to damage the battery with it and I doubt I will. Even less of an issue if all I really need to do is keep it between 30 and 80.
I've read also that a complete discharge every once in a while is recommended but not sure how accurate that advice is.

Li's are born to die; they start degrading the moment they're assembled. Don't go too nuts, just replace them as needed.
Until I watched someone replace my N10+ battery I was very concerned. However I realized it's relatively easy with the right skillset and tools.
Mind you they say the N10+ is one of the more difficult ones to replace... meh.
Now I don't really think much about it.
