[Q] 2A charger and matching Kernel/ROM - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi,
My mom has the old original 1.0A charger for the Note 1 and its started to stamming at charging so I wanted to order her a new one.
I'm using the new 2.0A for Galaxy S3/4 on my xperia Z and it charges up quick and works great. Although the original charger is 1.5A so it might "use" to the quick high Ahmp charging..
Is the Note 1 able to suck up 2A charge just like that? I've searched up a lil and saw that it might needs a profit kernel for that..
She has an old 4.0 ROM (probably over 1 year old), that mostly doesn't support it if its needed..
If so what ROM / Kernel can you reccomend that might fits it?
Any info you got about this could help.
Also if I'm already here, could you please reccomend of a new ROM (4.1/4.2 or anything higher than 4.0 ) that is stable enough for daily use?
Thanks thanks thanks ahead!! appreciate all your answers!
Yarden.

The Note isn't able to suck 1A IIRC, only through hacks. Still, the device charges pretty fast with a standard charger, just make sure it's being detected as a AC charger and not a USB charger.

Is Note charger same as Galaxy S2 charger?

Hi,
Getting an EU version of the Note, so I need to buy a Uk charger, is the charger for the Note and Galaxy S2 compatible? Thinking buying a 3rd party Galaxy S2 charger on ebay.
Many thanks
I suspect any 5v microusb charger delivering over 0.5A will be fine.
Expansys sent me a standard HTC one (5v 1A) with my german note and I am in the UK.
Thanks, I have a couple of generic USB wall chargers at home, so might as will use them with the Note.
I can't answer the question directly, but that big screen, fast processor and larger battery are going to take a bit more juice than your average phone, including the S2. When it comes to mains chargers that may not be a big deal, unless you leave the phone active while charging, but might become an important consideration if trying to use the phone for satnav in the car, for example.
At the moment I'm using an Orange San Francisco. That has a 3.5" OLED screen and a 600MHz single core processor, so hardly an energy guzzler. The supplied charger is rated at .7A. In the car, when using satnav, my generic USB car charger cannot quite keep pace with the energy demands of that little phone and the battery level actually drops slowly while connected to power in the car. I'm definitely going to be looking for something more robust for the Note.
Note charger is 1 amp, Nexus S .7 amp, Note charges fine off the .7 amp charger.
I assume a standard Samsung GS charger would do, the output on it is 0.7A?

Surprise, my car charger was not good enough for the S2 while using nav software, but the Note charges nicely.

Or should I just purchase a Euro/Worldwide adapter to UK plug?

You not only need a charger that can deliver more oomph, but also a lead or charger, possibly modified, that will allow the phone to draw that current. I have 1A USB chargers for the car but a regular data/charging lead only permits the phone to charge at the standard USB maximum current of 0.5A. I had to open up one of my chargers and solder the two centre pins together. Shorting those two pins signals to the phone that it can draw the full "mains" current rather than the 0.5A USB maximum.
I haven't yet charged the Note in the car, but on my previous phone the charging status would show "Charging (USB)" prior to the mod and once modded it would show "charging (AC)", which is what you need to keep the phone charged and charging while in use rather than slowly depleting.

I can confirm that SGS2 charger works on note. However charging is slow ( its 0.7 A )
However the note charger ( 1.0 A) charges faster
dont have a 2 A charger to test but I would say that it would be the same speed as 1 A charger.
If we want faster charging, we will need the kernel to modified.
The downside would be shorter battery life.

Would it work to get an adapter from the European plug that comes with the note to US outlet?

Thing is would the USB cable that comes with the note (designed for computers) be suitable in carrying 1000mAh?
I heard that USB cables that come with phones are 0.5mAh so it won't make use of the 1000mAh...
Can anyone confirm this? If so then it's better to buy an out and out 1000mAh plus wall charger or a worldwide travel adapter.

That's also what I want to know.
There is no reason why it wouldn't work. It's just like going on holiday... US plugs to Euro/UK etc
So that's the route I will end up taking. But I may purchase an out and out 1000mAh wall plug anyway... even a 2000mAh...

yes it will work fine, because the charger accepts 100-220vac 50/60Hz
The Samsung power adaptor that comes with the Note is a Universal one (110 Volts - 240 Volts) and is rated at 5 Volts 1 Amp output.
If you need an alternative for some reason (or a spare).........
Personally, I am using a generic iPad mains adaptor with dual USB sockets. The device was made in China and has a total current output of up to 2 Amps. It is a also a worldwide model. I think it charges faster than the Samsung charger.
It also charges the Note when using the MHL>HDMI output. I have read some postings that the Note very slowly loses charge when the MHL>HDMI adaptor (which has to be externally powered) is in use. With this 2A adaptor, it continues to charge.
You could also try the Genuine iPad adaptor that also works worldwide and delivers a genuine 1 Amp rather than some of the cheapie models that struggle to supply that current.

[Q] Quick Charge 2.0 confusion

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

@zephiK You misunderstood my question. The problem I'm looking to solve is the slow charge rate from the chargers in the original post.
To add to that. My macbook also charged my old galaxy phone @ 2amps but with my n6 only does 500mA.
Nothing wrong with the turbo charger

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.
@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand
Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.
Thanks! I guess I'll have to replace the chargers/battery

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.
I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people

[Q] Quick charge

Hi guys,
i have a european model of the S5 mini (SM-G800F) that comes with a 1 amp wall charger.
I read in another thread that firmware supports up to 2 amps in current. Can somebody confirm this?
I want to buy a quick.charger from amazon (Aukey PA-U28) to charge it faster. Will the phone charge to 2 amps? Can someone confirm this?
Thanks in advance
I am using my phone to charge with my tab's (EP-TA10EWE with 2 amps) and my phone charges normally, but faster.
Can I ask you how much time does it take for a full charge compared with the stock charger? Thanks
Okay, but it takes some time, 'cause my device is fully charged... I will try to make this experiment as fast as I can.

Options for fast charging.

Hi
I have the P9000 on the way and I am looking forward to it arriving. One question I have is what are my options for a fast charger? I am in the UK so require a three pin plug and don't want to have to use an EU to UK adapter. Am I able to use one of the many fast chargers on Amazon that say they work for Qualcomm's Quick Charge but do not mention PE+?
Thanks
i use the supplied cable with a three pin usb to UK wall adapter that we all use with older phones.
never timed it but it charges within an hour or so, its much faster than any other device i have on the old charge system.
no need to buy the 2 pin fast charge device their trying to flog on their site.

Yes, agreed, my phone charges quickly, whether using the fast or a standard charger!
I'm using a Lumsing 4-port charger (the "old" model without QC 2.0; 2.1A max per USB port) and it charges my phone really fast, I'd say about 60% in one hour. So I dismissed my plans about buying the official quick charger

what is the output amp rating on your charger?
I just bought an Aukey QC3.0 charger and it does like 80%/h
I bought a meizo PE+ charger and it does the job. Around a hour form 0 to 100%
Are these chargers that you use safe / fully compatible

How quick?
Everyone saying that the 'output amp rating' on 5V only output chargers is the way to determine if you're fast-charging your Elephone P9000 is unfortunately incorrect. A phone with PE+ uses load modulation to signal to a compatible charger that it should adjust its output VOLTAGE. There's a datasheet available somewhere that describes the protocol, but basically one set of current pulses (can be observed on an oscilloscope) means turn up the voltage, another set means turn down the voltage.
I managed to observe this behaviour, and simulate a compatible charger with a bench supply. When I saw the current pulses indicating a 'please increase voltage' signal, I wound up the volts on the supply from 5 to 12 volts, and the phone would draw up to 1A at 12V. If I left the supply at 5V, I would only see a maximum draw of around 1.7-1.8 A.
All this means is that compatible chargers are running at up to 12 Watts, whereas "high output current" chargers which only put out 5 V will only charge the phone at 9 Watts. Also, this is not compatible with quallcomm's quick charging system, which actually uses the USB data lines to request the increase in voltage.
Also, in general, cables are important. Phones will monitor their input voltage, and if they see it drop below some threshold, will reduce their charge current to match. If your charger doesn't have the current capacity to shove out to your phone, then the supply voltage will droop there and the phone will reduce the load. Similarly, if there is too much voltage drop down the cable (V=IR, R is the cable resistance, I is the current draw, V is the voltage drop) then the charging current will also be automatically reduced.
Also, strangely, my elephone p9000 recently stopped doing the PE+ thing! Now, there are no current pulses, and it only draws at 5V. *confused
I totally agree with the explanation of robot-army.
The Pump Express + charging technique is more than a simple current flow grossing.
This subject have been analyzed on another phone using the first mediatek Pump Express design used in the Zopo Speed 7:
http://forum.xda-developers.com/speed-7-plus/general/mediatek-pump-express-plus-zopo-7-t3336430
In that thread, you'll find the document that explain clearly the signal pattern awaited by Pump Express chargers to give their full potential. Without this management, they're just normal chargers and could be used in any other phone or device using USB standard to be supplied.
@robot-army: your problem regarding Pump Express management is known and it seems that since update 20160608, the kernel doesn't include this function anymore...
I saw that you shared your issue in the official Elephone forum on the following thread:
http://bbs.elephone.hk/forum.php?mod=viewthread&tid=11411&extra=page=1&mobile=2
I don't know if the kernel source used by Deepflex will let him put back this option ON in his CM13 Rom as it's an important feature of this phone and it seems that the Elephone Software checking team is not very serious about this point...
The lack of control of an highly advertised feature is a remarkable flaw, and even the last 20160715 update available doesn't correct this important point!
Please Elephone team, have some respect with your customer. The P9000 has a very good hardware basis, but you're making people changing their opinion because the software basis is not handled properly.

I totally agree with the explanation of robot-army.
The Pump Express + charging technique is more than a simple current flow grossing.
This subject have been analyzed on another phone using the first mediatek Pump Express design used in the Zopo Speed 7:
http://forum.xda-developers.com/speed-7-plus/general/mediatek-pump-express-plus-zopo-7-t3336430
In that thread, you'll find the document that explain clearly the signal pattern awaited by Pump Express chargers to give their full potential. Without this management, they're just normal chargers and could be used in any other phone or device using USB standard to be supplied.
@robot-army: your problem regarding Pump Express management is known and it seems that since update 20160608, the kernel doesn't include this function anymore...
I saw that you shared your issue in the official Elephone forum on the following thread:

Magnetic charging tip

Hello everybody and happy new year!
My original super fast charger which came with the phone won't magnetically charge my note 20 ultra
with the charging cable which I used with my Samsung note 8. I already ordered new pd 60w quality cables+new pd magnetic adapters.
Since I did not find any information -Do I have to buy new magnetic tips (which are stuck in the phone) or can I use the same tip which I used with my note 8? Are there any differences between tips?
Thanks for your help.

P.S - I am using my Samsung note 8 charger with the magnetic cable adapter in the mean time. The only problem is the slower charge....
If the previous setup didn't work for the new phone, you'll need the new tips too, most likely.
However, especially at the 25W fast charging speeds of the phone, I'd recommend you steer far, far away from magnetic chargers. Sure, it sounds like a nice idea, reducing the stress on the USB port, easy tear-away charging, and so on, but since most of these chargers are incredibly low quality, with bad contacts, you can expect a lot of loss, which manifests in the shape of heat. I remember with my Note8 I did the same, and the phone would get uncomfortably hot - and that was only 15W. Imagine what 25W would do.
The only magnetic chargers I trust are the ones specifically made and tested for the device - e.g. Apple's (old) MagSafe on MacBooks. And even those had heating issues.

The super faster charger doesnt play nice with alot devices iv come to find. I had an issue using a 2 in 1 charger/ aux adapter. The charger kept connecting and disconnecting. It seems to be some thing special to that brick specifically. Especially since its a 45w charger and I tried a ravpower 45w charger and it did not super fast charge my phone. Soo, yea. Super fast charging will only happen by way of samsungs official charger... which doesnt like alot other add-on devices (dongles, magnetic tips, ect).
