Charges faster in phone...while using!
If battery is around 40% it being be charged overnight.
Anyone else experience this?
could be the amp? maybe below 1 amp? Samsung charger has 2amps om it. check your charger and look for the amp. btw. the lower the amp the better for your battery..
Buy an OEM charger. The Samsung one is $50 from Samsung website but you can get the Asus charger from Google play store for $25. Both are two ampbi believe. Or you can get the 1a for $25 from samsung. Getting OEM directly from an OEM or authorized reseller or a storefront lime Google is key. Getting cheap chargers is gonna bite you in the ass one day or think about it like this. Why keep wasting time buying cheap chargers again and again when you can put up proper money and get quality in one go and have peace of mind for a few years. I even stopped buying chargers from amazon because they're just cheap knockoffs too. Phi hong makes good chargers and power supplies but they are harder to source. Phi hong came with my nexus one andy galaxy nexus OEM Home dock.
Anyways, aside from that part of the reason for slow charging is you probably have an unsafe charger that is not rated what it really is and is made of poor materials. Getting a quality 1a or higher, preferably 2a in this case and your gnote2 should charge @ 1.8a. In other words, you can charge from zero to full in ~2-2.5 hours. Or from partially full to 100% in less than 2 easily.

Unless I am mistaken, OP is referring to battery chargers, not usb chargers. That's how I charge mine, too. I have spare batteries, and they all get charged directly. When my battery is low, I just swap. I hate having my phone attached to a cord, even at night.
Yes, all the battery chargers I've had for every device (including this one) have been lower amp than the usb chargers supplied with the phone. It is especially slow for this huge battery for the Note 2. While it bothers me in concept, it's never actually been an issue for me, so I haven't done anything about it. I don't know if higher amp battery chargers are available, but I don't feel like spending extra money on one.
As far as battery health goes, charging at a lower amperage certainly isn't hurting the battery. If anything, it's actually better for it.
Yes...charging just the battery with wall charger.
@ 40% it will not be charged at 6am when I wake!!!
Are there better wall chargers?
Why do you hate having your phone attached to a Cord overnight. I heard that's fine and do it every night.!

Not for the phone, for me. It just bothers me having a wireless device locked to a wall. There's no reason for it. And I frequently get up in the night for various reasons (kids, work, insomnia, etc), and it bugs me unplugging in the middle of a charge cycle.
Incidentally, a non-removable battery was a deal breaker, and one of the reasons I didn't get a Nexus 4. I got used to never plugging in my last phone, and I don't want to go back. It was torture the first week or two with the N2 before my spare batteries arrived.
The charger should have its output printed on it, I've had a look at the pics on ebay and the first two I found that I could read were 500mA and 350mA, the original charger is 2A or 2000mA. Samsung make there own battery charger http://www.samsung.com/au/consumer/...es/EB-H1J9VNEGSTD?subsubtype=other-multimedia the output is 1.7A so much closer to the original usb charger.
I'd be worried about my back cover getting loose doing what you do. I had three batteries for my old phone, but I did not swap them on a daily basis, just when travelling or away from power for an extended time. I've ordered some wireless chargers so I can have one by my bed and another downstairs. I know they only output 500mA too, but for an overnight charge thats fine for me. I dont think there is any issue with interrupting the charge cycle, the two main enemies of lithium batteries are heat and being totally/almost discharged on a regular basis. Its best to keep them topped up.

It looks like the OEM battery charger is available on ebay for around $15. That's good to know in case mine ever crap out on me. These cheapies that I get tend to.
As far as the back cover getting loose, after 3 months, it is a little bit looser than when it was new. 1.5 years with my G2x didn't loosen it at all, but the build quality on that thing was fantastic. I keep this in a case anyway, so it being a little looser goes unnoticed. If it gets bad, back cover replacements are cheap.
If one of the devs can make the kernel capable of fastcharge, it would not take but half the time to charge. Yank who is working with Faux on his kernel, helped make the kernel fast charge capable.

But what is the point of having it charge fast, when all it is is going to drain faster?
I charge mine overnight with a charger rated at 750mah I believe and it last me a whole day. As oppose to using a 2.1 am charger I have, where the battery percentage would start dropping by the first hour.
Correct me if I am wrong here, but this is what I've notice with my last few phones.
The Perseus kernel with stweaks has the ability to change the charging parameters.
With it overclocked/undervolted I am getting better life than I did on stock.
Not for sure what you mean as it depleting the charge faster on a higher amperage charger. Kind of sounds like you may have had failing batteries, etc.
There seem to be a few misunderstandings here regarding batteries and chargers.
1) The charge rate, when the battery is in the phone, is controlled BY the phone. The charger itself just supplies regulated power to the phone. How much current is put into the battery at any given time is up to the phone, which is why kernels can do things like fast charge, it's controlled by the kernel. Now, the reason the battery charges faster when using the stock charger vs. something lower current or a computer is simple. The phone can detect what it's connected to within some limitations. It sounds like our phone can also sense the incoming voltage levels and back off if the supply becomes unstable.
2) Using the stock 2A charger is "harder" on the battery than a lower current charger. Not true, at least not within any margin of error you will be able to detect without specialized equipment. Lipo batteries are generally built to charge/discharge at 1C. C in this case stands for capacity. So our 3100mah batteries can charge at 3.1Amp and be within safety margin. So the 2Amp charger the phone comes with is perfectly fine for the battery. Without seeing a datasheet for the battery from Samsung, that's a good guess. And again, the phone controls the charge current based on a number of parameters. You could connect the phone to a 5V supply capable of 100Amp and it will still only use what it needs.
3) The percentage readout on the phone screen is a GUESS. Don't pay it too much attention. For this same reason, evaluating 3rd party batteries based on phone runtime etc is not useful. To validate the battery capacity with any accuracy requires a test setup discharging the battery through a known load and measuring how long it takes to get to a cutoff voltage. I've done some of these tests myself on stock and 3rd party batteries. In general, the OEM batteries are always at or above spec, the 3rd party battery manufacturers lie. Often by upward of 20%. Even the high $ batteries. Keep that in mind when shopping if you want extras or extended batteries.
4) Interrupting the charge cycle is bad. Nope. It's fine. On this same line of thought, full cycles ARE bad. Don't do it. Don't think too much about it either though. Just plug it in when convenient. Or set it on the wireless charger if you've installed one. Generally speaking, they actually don't like to be charged to 100% either. Keeping it at 20%-80% is actually best for the longevity of the battery cell itself. In practice, you will probably have a new phone before any of this is actually noticeable.
The OP sounds like they are talking about a stand-alone charger, where the battery is not in the phone. Those will vary wildly in quality and capability, particularly from ebay. They are probably cheap POS devices. Not that that's really a bad thing, just know about it. It's probably a very low charge rate device, perhaps even down to 100ma or so. That would take forever to charge our larger batteries. As for if there is a better one, probably. If Samsung makes one, it will probably charge faster than the phone with the provided charger plug as there would be no load from the phone using power. Of course, it will cost a lot more as well. Look for devices that at least claim they will charge at 2Amp or so. In practice, they will probably be a lot lower, but your chances are improved. Not many people will break out an ammeter and check, after all.

Perseus kernal has fast charging settings.
What ttabbal wrote is mostly correct. But the problem lies within some input voltage protection logic tied to the charger chip of the phone which is extremely (and too much so) sensitive.

Can people stop calling it fast-charge, it's an idiotic term which technically means nothing. While most kernels have some sort of charging speed configuration options, they're all useless in regard to this problem as the current in the end is decided by a different logic. You'll have to disable unstable power detection and that's the only way to make it work and fix the problem, unless you go hunting down high quality cables and chargers.
Personally I also encountered the problem as my stock S3 charger, as many others here have reported, has deteriorated and it would only charge at an effective 300mA. I disabled unstable power detection and now it charges at the full given current limits, without any issues.

You have to make sure it's "2a" charger capacity. It happened to me once. Go to monoprice.com and search for a universal 2a charger... pretty cheap
So now that samsung decided to remove the battery, it would only make sense to have a portable battery pack handy.
A friend of mine let me borrow his RAVPower 15,000mAh power pack and i have been testing it on my S4 to see how well it works, so far i am impressed with it, but i've only charged the phone twice, trying to see how many charges i can get out of it. will update this thread and post a better review of it later when i get better impressions of it. i also have an brand new Anker power pack i will be testing later on. primarily interested in charge speed rather than charge cycles. will update this post a bit later with more information and power packs.
link: http://www.amazon.com/gp/product/B00MQSMEEE/
I found this article linked in another thread over at Android Central http://www.phonearena.com/news/Doub...honeSuits-snap-on-Flex-Pocket-Charger_id66907 and this is a nice pocketable charger that doesn't require you to have a cable on hand to charge.
Here is PhoneSuits page http://www.phonesuit.com/phonesuit-...-smartphones?gclid=CJ35qJvdk8QCFRMatAod43cAAg and its listed at $49.95.
that's quite a bit of money for only 2600mAh, guess it's small so that is a plus, but if you want something that can charge several phones with one charge i would go with something like this:
http://www.amazon.com/gp/product/B00NWEB49W/
it even doubles up as an actual wall charger.
smaller than a pack of cigarettes and a bit cheaper than that 2600mAh power pack.
I have this one. It's 10,000 mah, which is pretty good for the price.
http://www.amazon.com/TechMatte®-10...UTF8&qid=1426265278&sr=1-3&keywords=powerbank
It takes about two hours to charge, and then to charge my dead s5 takes about 1 hr and 45 minutes.
I have a Samsung one with 10000mAh and it is pretty good. With a 2000-3000mAh you are not even going to charge the phone up once, so pretty much useless.
I have been using Anker 2nd gen Astro2 for a year now , looks good with plenty of juice , and as per manufacture specs it can push out 3 Amps , 3 Amps is useless on my S4 but it should be perfect for S6.

forget finding a "fast charge" on portable chargers. highly unlikely you will find one. maybe in the future when someone figures out and implement some kind of voltage step-up regulator as it's a limitation right now since to get fast charge to work you need 9 Volt output and current portable chargers can only output @ 5 volts. it's basically a limitation on the internal li-ion batteries, they can only output 4-5V.
your best bet is to get something like the Anker 16,000mAh for high capacity and pretty fast charging, it can output 5V at 2.1A, it will charge most phones (Galaxy S4, S5) in about 1 and 1/2 hours from about 8% battery left on the phone. you might only shave off only 15-20 minutes using a samsung wall fast charger, so it's really not a whole lot difference..
Anker 16,000mAh 2nd gen:
http://www.amazon.com/gp/product/B00N2T7U90/
it will charge an S4 or S5 roughly 5 times with a single charge.

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.

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.

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.

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

Most chargers I've seen are using 1-Coil instead of 3-Coils. This means the magnetic field produced is not as strong as it could be. Chargers with 1 Coil are very picky about placement. 3-Coil chargers are less picky and allow flexibility when placing.
Adapter Rating
Some people are having problems with their devices turning on and off when charging. I would suggest checking the specs on your AC/DC Adapter. The more output current. Try using adapters with a rating of 5V ~ 2.0A. If your device gets too hot try using one that has 5V ~ 1.0A or even 5V ~ 1.5A. The current is responsible for inducing the magnetic field, which chargers your device. More current = stronger field.
Fast Wireless Charging
On June 23rd, 2015 the Wireless Power Consortium made an announcement stating that Fast Charge 2.0 technology is making it's way to Wireless Chargers. This means that wireless chargers will charge about 60% in 30mins! Just like our Adaptive Chargers can. I'm holding off on buying my wireless charger until then.
I wanted to post the article but the forum won't let me until I have 10 posts. Just Google it!
In case you're wondering I am an Electrical Engineer! I did my homework before posting, haha.
Thanks guys!
The S6 edge won't support 15w wireless charging so just buy a 3 coil charger and enjoy, we might see 15w wireless charging on the S7 if we're lucky
Apparently it's backward compatible. So all current Qi-enabled devices should be good. The only problem will be heat. 15W might burn some of the circuitry.

Chances are that, in this context, "backwards compatible" means it will still be able to charge devices built to the earlier spec, not that it will charge them fast.

Also the current on your adapter can be whatever you want 1A or over, the rate of charging will only be 1A. It will get no hotter using a 2A adapter.

That would be my guess.
Hello!
i've bought Nillkin Disk Charger III which support fast charge (9V/1.7A max 10W) so does original Sony XZ2 charger and XZ2 itself. Sadly, when charging using Nillkin, XZ2 uses normal charging mode, not fast. 25% in hour. Only 400-500mA on wireless charger vs 2600mA on cable. With or without phone case, doesn't matter.
What can I do to charge it faster?
Bump.
Buy offical one by Sony
I use this one and all is fine. https://www.amazon.com/dp/B01KJL4XNY/?tag=flv-21&ascsubtag=6987aeb4-b272-4b5f-935b-f94acfec1a3d

Can you download Ampere app from the play store and run it while charging on this Anker pad. Let us know if this one can really charge the XZ2 beyond the standard 5w speed. Report the mah if it can exceed the 800mah standard qi rate. Remember, fast wireless charging at 9-10w should be around 1400 to 1500mah.
I have tried 7 different brands of fast 10w wireless chargers so far (but not an Anker yet). None of them can exceed 800mah on the XZ2. I wonder if the official Sony one can really do it at 1500mah.
So, please use Ampere and report back your results with the Anker, thank you!

max with the Anker QI charger was 760mA. I use it to charge it at my office. I never cared about the charging speed A friends Galaxy S9 can use 1420mah with the same charger.

I think this video can give you an idea of the Sony wch20 charging profile: https://youtu.be/BnasDqGFcFg close to 1500mah but not for a long time.
I too have a similar question. But it's about maximum allowed power for XZ2 wireless charging.
I just talked with Sony support and they too have no clue how XZ2 Qi wireless work. They told me better to buy (if at all) other brands' chargers with output NOT exceeding 9W, since it is the maximum output by the official Sony wireless charger.
But apparently some 3rd party brand reps told me that Sony uses Qi 3.0 and 10W chargers are completely fine. And all fast charger on Amazon output 10W with Qi 3.0 adapter.
So I am really confused whether those faster charger is safe for XZ2 at all.
'And it is very confusing that the Sony original adaptor has 3 working power: 5 V 2.7A DC, 9V 1.8 A DC, 12 V 1.35 A DC.
What do you guys think?

That's called Qualcomm Quick Charge.
While USB is specified for 5V QuickCharge 2.0 can use 5V, 9V and 12V (not used in phones).
QC 3.0 is even better as it has adaptive Voltage scaling from 4V to 9V theoretically.
Practically it's around 4.6 to 7.5V changing fluently during the charger process.
For normal cable powered charging the device itself decides how much amperage it wants to draw. The wall charger can only set an upper limit like 'only has 1.5A at 5V'
As wireless charging sends out power I think there is a communication between sender and receiver which handles the power output. Haven't really read much about that though.
Hi,
Has anyone found a charger other than the official one that will charge at more than 5W? I bought a 10W wireless charger from Amazon and it only charges at 5V 1A whereas the same charger charges a friends iPhone at 7.55V 1A. Has Sony built something into the phone/software that only enables 9W charging with the official dock?
Thanks

Not so far. Got a Seneo fast wireless charger and some other brand I can't remember the name of; both tried with multiple QC charging packs I have lying around (and even Sony's brick supplied with the phone). According to AccuBattery, the XZ2 never pulls more than around 700 mAh, while my Lumia 950 XL hovers around 1700.
I'm thinking you're right, there is something special the XZ2 looks for in their WCH20 wireless charger unfortunately. I've tried turning Battery Care on and off too but that hasn't changed anything as far as raising the current draw.
I really have to try it when the battery is below 20% though to be a fair test.

Update: So I bought an Anker Powerwave wireless charger and QC3.0 adapter which Anker claim supports 10W charging on the XZ2. I have tested it and it charges at 7.45V at 1.2 Amps so not quite 10W but it charges from 0 to 100% in 2 hours 50 minutes which is much better than the first wireless charger i bought which took over 4 hours 30 minutes at 5W. Hope this helps.

actually, 7.45v at 1.2A is 9 watts. Which is reportedly the XZ2's peak draw.
A couple questions:
What did you use to check the charging stats? (I'm using AccuBattery currently). I don't think the latest Xperia phones have any fast charge indications like some other OEM's do.
Was the 7.45V/1.2 amps reading at 0% battery?
Was Battery Care enabled?
Did you happen to check the charge levels at various times during the 2h 50m and see if it fluctuated?
I'm using an Anker QC 3.0 charger with my Seneo which charges great over USB, so I don't think my problem is the charger. I'm going to let mine go to below 20% and try again.

I use accurate battery on every device I maintain.
At least to give an alert, if 80% battery capacity is reached during charging.

Sorry, yes I know its almost 9W. I was just making the point that it didn't reach the 10W Anker claim it can.
I use an inline USB amp meter...
The 7.45V 1.2 amps was from 0% to 70% after that it was 7.45v 1.0 amp until 100%
The 1.2 amps could only be achieved by careful positioning on the pad, if it was slightly to the left/right it would drop to 1.0 amp.
Battery care was disabled.
Thanks

I think the 9W cap is Sony, not the Anker.
I'm going to send back my Seneo, obviously something is not working right with the XZ2 regards fast charging. Tried it with several different QC chargers, moving it around on the pad etc..
Thanks!

No problem
I would love to test out the WCH20 but in the UK Sony want £129. Have found it on Amazon for £70 but it's still silly money for a charging dock!
If you're considering the Anker Powerwave, it is very good. My only gripe is even though it stops charging once the phone reaches 100%, the cooling fan keeps running until you remove the phone from the pad which seems like an oversight.
Cheers.

Hello!
i've bought Nillkin Disk Charger III which support fast charge (9V/1.7A max 10W) so does original Sony XZ2 charger and XZ2 itself. Sadly, when charging using Nillkin, XZ2 uses normal charging mode, not fast. 25% in hour. Only 400-500mA on wireless charger vs 2600mA on cable. With or without phone case, doesn't matter.
What can I do to charge it faster?

I have the Nilkin charging stand for my XZ2 Premium and I am more than happy, it takes about 2hrs to go from 50% to full charge, it will never be as fast as wired charging, and the battery life on the Premium is great, I can easily get 2 days but would rarely need that.
Sony WCH20 can do 1700 mAh but only to 50% of battery charge. After that it is slower 1400 mAh and that again slower.

Guess I'll have to try the Anker Powerwave (which one did you get if I may ask?). I tried yet another brand, which again, fast charges my old Lumia 950 XL just fine around 1600 mAh, but the XZ2 refuses to go beyond ~700 mAh. Wondering if it's my phone or the XZ2's coil is just in a weird spot.
I'll have to spring for an inline USB meter. maybe it'll help me find the "sweet spot."
