Have you ever wondered how an EP800 compares to an EP850, or an iPad charger? I have. Reading the comments on the forum there is a lot of subjective opinion, but little in the way of facts. With this in mind I decided to make a little app to measure how long it takes the phone to charge from 20% to 80%.
20% was chosen as the start because readings below this have a high uncertainty
80% was the ceiling because the Xperia shows down charging somewhere around 90% to protect the battery.
I wanted to ensure I was measuring the charger at its peak output.
So far I have done 3 runs:
EP800 (rated 850ma) with normal USB cable, 8845 seconds (est 427ma)
HTC B250 (rated 1000ma) with normal USB cable, 7910 seconds (est 477ma)
Unbranded (rated 1500ma) with "data" cable 3120 seconds (est 1211ma)
My current suspicion is that the charger is not as important as we have previously believed, it could be all about the cable. I will run some more tests over the next week using the same charger with different cables.
In the meantime, if anyone wants to give it a go, my app is available here
https://play.google.com/store/apps/details?id=com.vexedbadger.chargertimer
(once Google gets around to approving it)
and my latest results are here
http://vexedbadger.com/?page_id=97
But I will keep this thread updated until I reach a satisfactory conclusion.
I am also eagerly anticipating the EP851. I wonder just how good its boost charge feature is. Could it simply be a normal 2A charger with pins 2 and 3 bridged?
If you do give the app a try, post your results here.
-----------------------------------------------------
For newcomers to this thread I believe I have made an important discovery. I ran a test using a HTC B250 1A charger. I did it first using a normal USB cable. I then repeated it using a USB charge cable (2 wires, no data lines) and got these results
Data Cable, 7910 seconds, est 477 ma
Charge Cable, 3530 seconds, est 1071ma
In other words the cable you chose to run between your charger and the phone is absolutely critical in determining the charge speed. Here I have observed over a 100% speed increase.
Using the supplied EP800 (850ma)
Data Cable, 8845 seconds, est 417ma
Charge Cable, 5170 seconds, est 731ma
Again, a huge difference.
Oh, and the BlackBerry Playbook charger is a beast.
I have just done a run with the BlackBerry Playbook charger HDW 34625 (2000ma).
20-80 in 2875 seconds. That means approx 1314ma output. An estimated 0-100 in 1hour 20 minutes.
I have a new charger of choice : )
Nice find, but is it good to charge the battery like that ?
I suspect you're correct OP.
I charge mine with a 1A iPod charger with an x10 cable + 8M Extension cable(sockets only on one side of the room), with that charging is pretty slow. Tried it without the extension but it wasnt noticeably faster. Then one time I used a 15cm USB Micro cable from an unknown device on the front USB port of my desktop(500ma maybe, probably less) and it was insanely fast.
So yeah, think its the cable.

My guess is that Sony know a thing or two about batteries. They control the amount of charge passed to the battery. A very conscious decision is made at 90% to reduce the power flow to the battery. I am happy to chuck as much power as I can at it.
Also remember that Sony are about to release the EP851, a high speed charger.
If I remember correctly if you connect only the power cables within a USB cable the maximum you will get from most devices is 500ma. If you connect all 4 cables as a regular USB data cable, the 2 devices communicate and then the phone will ask for maximum current from the USB host. This could be several amps. This is why there is a variations in charging times. Try several different cable on the same port, then try them all again charging from different hosts, ie. OEM USB charger, computer usb port, other USB chargers.

I think you are close top the answer there. The USB 2.0 spec says 500ma per port. This spec was written long before charging smartphones via generic USB cables became the norm. Some manufacturers now offer high ampage ports on the motherboards. I know Apple does, my aBit one does and a few gigabit ones do.
The phone tries to detect if it is being charged from a computer USB port where it is capped at 500ma, or from a power supply that supports more than this. There are two conventions that I know of. Apple puts a resistor between pins 2 and 3 (the data pins). IF this resistor is present hen the device charges at full power. HTC (and a few others) rely solely on pins 2 and 3 being bridged. I think this is the USB standard as well. Some batter apps will tell you if the detected charger is in AC (high ampage) or USB (capped) charge mode. The speed difference is pretty dramatic.
Some cables come with pins 2 and 3 pre-bridged. They are no good for syncing but great for charging. I am running some tests with one now.
Interesting app, I have a bunch of random USB chargers and such floating around. I use as my standard charger the 850, but I have wondered if I can get better charge from the piles of other chargers floating around.
I also have a BlackBerry bold charger (direct connection to phone via fixed USB cable) do you think that could perform better? I guess I will test it out first.
Thanks again for your useful apps! I used the nfc one and love it

So having a current up to 1.5 A or maximum current of 5A, which one is it?

No. The second one means 5A, if you bothered to read the specification whitepaper.
And my post explains clearly the difference between 1.5A and 5A current:
1.5A for "UNCONFIGURED DEVICES", and "HIGH SPEED COMMUNICATION WHILE HAVING A CURRENT UP TO 1.5A"
5A is the MAXIMUM ALLOWED CURRENT.
The Xperia Tablet Z is a notoriously slow charger and won't charge over USB (from what I've heard, I don't have mine yet). Does anyone know of a portable charger or power pack that'll work with it?
Ideally one available in Europe.

The Xperia Tablet Z is supplied with a charger that connects to its USB port; so, the XTZ will charge via its USB port.
If you attempt to charge the tablet via a computer's USB port, that port must be capable of supplying enough charging amperes, otherwise, the tablet will not charge. Standard USB 2.0 ports supply up to 500 mA and standard USB 3.0 ports supply up 900 mA, neither of which is truly enough amperes to charge the tablet. USB ports on computers that are specifically designed for charging devices usually supply 1500 mA (1.5 A) or more. Some manufacturers mark these types of USB ports with a lightening bolt symbol.
As for portable chargers, I have not used any except for chargers that fit in my automobile's power plug (cigarette lighter plug).

Any halfway recent (read: last 5 years) USB charger will work with it. Be it the one Sony supplies with the tablet, an iPad charger...or one for the Galaxy Note 2.
USB chargers are standardized, you need a "special" one nowadays about as much as you need a "special" socket for a device with a power plug.
The only difference is that we have weaker and stronger chargers, but this does not limit their usability. If you use a weak charger your device will charge slower, if you use a charger with an higher maximum power as your device needs it will expl nothing bad will happen either, it won't take more from the charger than it can handle.
Personally I bought (since I need the original 1.5A charger for the dock) a 2A Samsung charger for travelling. I think it is the same as the Galaxy Note 2 uses, which you already have.
Oh, and it charges with the 2A one over USB also around 30% faster than with Sonys 1.5A.

Maybe I'm not being clear.
Portable power supply. With a battery. One that puts out enough power to actually use the XTZ while it's charging, even if doing so only keeps the battery the same rather than actually charging it.
Can anyone recommend anything?
I know it uses a standard micro USB connector to charge but I've heard it won't charge from most PCs as they don't put out enough power. My understanding of many portable chargers is that they also don't put out a great deal of power unless specifically designed for laptops and the like. I don't know if the tablet's needs are quite that, but I'm looking for anyone who has experience using a battery pack with it and if anyone has any recommendations.
Or am I being silly and it'll work with anything capable of charging any tablet?
Thanks.

It should. The XTZs battery isn't exactly high capacity as tablets go. The Nexus 10 has a 50% bigger one and the iPad3/4 one is almost twice as large.
The principle of power packs is in the end identical as that of basic USB chargers, even a 500mA one will charge the XTZ, but it will take around 15 hours for that (and around 24+ hours to charge an iPad). It isn't a question of "working", but of "working how fast". But, as said, the XDZ hasn't exactly an huge battery, so if anything it will charge faster than other Tablets.
Assuming you do not use it, that is. It is quite possible to discharge it as fast a 3A/hour if you use maximum screen brightness and CPU intensive tasks. But you can discharge other Tablets faster than you can charge them as well.
So what to use - same principle as with USB chargers, pick any. It does not matter if its power comes from a power plug or batteries. If ti works for one USB device it will work for all. What matters is it's maximum A output. One with 2A should be able to charge the XTZ in 4.5 hours, one with 1.5A in 6 hours, and so on...

There is a slew of chargers that will charge it. You can use laptop USB, but like mentioned if you use it while charging it will drain
To solve this problem you simply need to have a portable charger that will put out at least 1.5amp(which is what the tablet charges at if im not mistaken).
So plenty are on amazon or ebay which you should have access to in europe
I use powergen ,they work well and is good quailty. Like either of these will workbigger mah will make the charger simply last longer)

Key thing is to simply look for the amerpage it puts out before you buy, that's how you know if it will charge and use the tablet at the same time. I can sucessfully do both using my car charger(2amp made for iphones) and my Powergen

The thing is this entirely depends how you use it. It is quite possible to use it in such a way that you would need a 3A charger to stop it from discharging. I do not think such one exists nor that the battery can accept such a charge.
So AFAIK a charger (be it a power plug or battery one) which stops it from discharging under all kinds of usage scenarios does not exist.
Therefore there is no answer to you "which charger I should use" question, only that the more A a charger puts out, the more usage scenarios will be covered (as in "will charge tablet while using it that way") by it.
Test how fast the Tablet discharges (without charging it) when you use it the way you plan to while using your charger. That will give you an indicator what kind of power you need. I.e. if it takes 12 hours even only a 0.5A charger will work, if it takes 2 hours you would need a 3A charger, which likely doesn't exists.
Im using an innergie charger that gives 2.1 amps and it charges a little faster than the 1.5a that came with it!

You know that that charger will only charge around 66% of the XTZs battery, though?
(Effective maximum capacity ~4A (see "attrition factor" explained in 2nd review), XTZs battery: 6A)
I am using my Samsung Note2 charger that states 2A.
Charges alot faster so for people with other chargers I should check samsung chargers haha.

cables
I'm planning to buy a quick charger for my Z3. Maybe i'll buy this one. I just want to know, what cable should i use? or will the default cable of the Z3 would enable quick charge? Here is the charger i'm planning to buy. Is quick charge cable dependent as well? can't find any post about the cables.
http://www.pure-gear.com/extreme-usb-wall-charger-849.html
I thought it was a Quickcharger (EP880), the one that came with the phone.
It is EP881.
If you buy a EP881, they give you a EP880 power adapter(this already comes with the phone) and a different looking usb cable. so i would say if you buy a z3 you already have a quick charger. someone in the z3 compact forums confirms this here: http://forum.xda-developers.com/z3-compact/accessories/magnetic-dock-quick-charger-t2926784
also if you google EP881 you can see multiple images of the EP880 power adapter.
i hope this clears up any confusion
EP880 is not a Qualcomm Quick Charge 2.0 charger
FYI, just received a Qualcomm Quick charge 2.0 compatible charger and the Z3 definitely takes advantage of it. I have the Tenergy Turbo charger and the light is blue for normal charging and green for Quick charge 2.0. The only downside is it doesn't seem to work using the magnetic charging port, only directly into USB.
Roughly how fast do you get a full charge?
I read that with 2.0 it rapid charges to ~65% and then normal rate.

Not sure since I only had it on for a little while testing today. No I don't feel like running down my battery and testing it, it takes to long to run down the battery
It absolutely, definitely charges at QC 2.0 speeds though, but only via the USB directly into the phone, not through the magnetic charger.

they are "quick charge" but not Qualcomm Quick Charge 2.0 spec. Maximum output for the EP880 is 5v 1500mA. Quick Charge 2.0 charges at 5v 2000mA (2A) or 9v 2A, or 12v 1.5A

If my memory stands correct, box version of the charger rating was mentioned as 3000mAh or 2000mAH. I might have misread it in the frenzy of getting Z3 and I am the 1st buyer in Chennai, atleast that's wat the retailer told me.
I forgot to take a snapshot at tat time. My USB cable version is EC803 and Charger (provided by service center) is EP880. I have searched throughout the internet and no where the output rating of Z3 box version of charger was mentioned.
Are u sure that the box version of Sony Xperia Z3 (D6653 LTE) has the same output rating of 1500mAH. Thanks in advance.

"quick charge" or charging at 5v 2A (2000mA) works through the magnetic charging port. This is still very fast.
Qualcomm Quick Charge 2.0, which charges at 9v 2A does not work through the magnetic port, which is not a surprise to me.

You already got it ?
Do not bother with quick charge 2.00, although snapdragon 801 support it I don't think our z2 software has that enabled.
Why I am saying that is because the maximum charging current the z2 draws is 1.50 amps (measuring it with one of these)
I've tried different chargers (oneplus charger, anker charger which both capable of 2 amps) and different cables and always the max is 1.50

Yes, I know about that already and I mentioned that in my comment. But as I said the z2 maxes out at 1.5 amps I think because of software limit.

Is that on a dead battery? Current flow will settle down as the battery reaches more charge for safety.
I use a 1A charger from my old HTC phone with the dock at night, but it doesn't feel to me like my Sony wall charger is any faster. In fact, it feels slower. The quickest charges I got were actually through my desktop, my motherboard has a charging feature on the USB 3.0 ports.

Ah sorry, guess I read wrong.
But as Sony and Qualcomm say the Z2 is QuickCharge compatible I think it should be working.
You can't see more than 1.5A because you do not have a QuickCharge 2.0 charger! And even if you would and then plug this USB anpereMeter in between it might block the data transfer making the phone think it is connected to a standard USB port.
I'm not even sure if QuickCharge 2.0 CAN draw more than 1.5A! We only know that it allows up to 9V or 12V.
There are 3A or 4A 9V chargers around. But I don't know how much the phone would want to get.
BTW. With Doomkernel and FastCharge enabled you should be able to demand more than 1.5A... I think up to 2A was available in FauxApp
But I think I failed when I tried. Not sure anymore... ^^ been a while.
Hi people
Since I'm part of the lucky people owning a Huawei Ascend Mate 7 (MT7-TL10), I'm actually looking some accessories like a quick charger.
I wish a charger better than the original one if possible, with EU pins, and with a good quality checked (I prefer to avoid some product with awesome specs but not tested ...)
So anyone have any idea where I can find a good charger, and without any risk for my phone ?
Thanks

for few days i went to jarir book store on KSA . I found Charger good price also 2 USB 5 volt 2.4 Amber ... compatiable with mate 7 and faster from orignal ...
just to know more fasting to charge wil damge your batter of mate 7 quickly .also orignal 2 A will damge
for me I charging with Iphone charge 1A good for batter and Stander and low risk to Device
If you want proper charging, then always use the accessories coming with that product. It is tested for sure and good. Other than that, you can use any charger delivering the same charge. The original charger is 5 volt, 2 Ampere. Don't use anything above 2 amperes as it may damage the device. Below that will charge it slowly.
BTW, why you don't want to use the original charger?

I use Nexus 6 Turbo charge (made by Motorola) 5v 1.6A it charge full battery in 90 minute.

Is it safe for battery life of Mate 7?
I'm using a NTT Docomo Quickcharge 2.0 adapter and It does support it even though is not specified and it's not a qualcomm chip.

Can you test it with ampere (free in gplay) i don't think it will charge over 1800mA so that it acts like a normal 2a charger
Fast charging
Using a fast charger will destroy your battery faster. Not recommended as the battery is not removable. You can get a battery and if you are comfortable removing the back and swapping it out then go for it.

that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.
Since battery is not removable be careful with fast charging, since it will decrease the life span of the battery and in the end it will just give you less battery performance.. it is stupid... however.. there is situations where it can be really needed though but not on a regular basis..
Last weekend I would really had needed fast charging.. It forced me to spend about 3 hours on a cafee so I could make it 100% so I did know I did survive the day with gps and all other things.. However in these situations I really like the ultra power saving mode..it saved me that night.. when I was lost in stockholm.. and my phone was really the only way to get contact with people

Why don't you buy a powerbank? I can advice you the xiaomi 16000mah. That one charges fast and you can be mobile.
Any recommendations?
I wonder if a S6 charger do the trick. Stock charger is too slow damn. Spending 3 hours to have a full charge is not acceptable for me.
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps. Batteries will automatically lose cells from charge cycles and by the time you feel the effects of the battery going bad, you would have already moved on to the next device for the next person to worry about. And saying to use the Stock Charger isn't really good enough as the Stock charger doesn't serve as a Car charger also. If you want to charge your phone quick, and you already have a 2 Amp charger, Check your microUSB cable. Don't use junk cables, buy quality or use the cable you received with the device. You get what you pay for. Fast Charging won't work as the Charger has a chip inside that communicates with the Phone and Device. Also, when buying a charger, don't just randomly buy a charger online, Make sure its UL Tested. Even if it says UL tested, there should be a test number on that UL Label, take it a step further and google it and make sure it matches the charger specs and passes as knockoff chargers are notorious for copying other chargers Regulatory icons to make it seem authentic. You don't want to buy a junk charger that ends up burning your house down or gives you a very bad 120 Volt shock through the microUSB cable that would also kill and fry your phone.

You have not read my earlier post or you did not understand it. Changing the charger on the Mate 7 will have NO effect (zero, nada) on the time required to charge your phone except the charger delivers less then appr. 1.6A. Then it would take longer and evetually kill the charger. The Mate 7 uses a Kirin chip which has no fastcharge implemented. Samsung uses Qualcomm Chips with implemented fastcharge technology. The charger (in fact a power supply) and the phone/CPU/charge controller need to communicate with each other, otherwise fastcharge will not be activated (the reason fastcharge with charge-only cables does not work because they lack the required data cables for communication).
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps.

Wrong. Correct would be "I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v." The amps of the charger don't matter at all -> amps are PULLED by the phone not pushed to the phone. You could use a charger with 100 or 1000 amps and it would not hurt your phone a bit as long as it is only charged with 5 Volts.
More amps (>1.6A) on the charger do not improve the time for charging one second.
1.6A is nothing. i use 2.0A and it still chrges 3 hours.

Yes, and that won't change one bit even if you use the best and most expensive charger and a 1000$ cable. The Mate 7 is limited by its hardware (built in charge controller) and pulls max 1.6A. End of story.
As long as you don't understand how charging works you will spend 100's of bucks for cables and chargers to no avail.
The only reason, why charging with some charges is quicker than with others is that those chargers actually deliver the amps they are supposed to deliver. There are a lot of cheap/bad chargers out there which are labelled with 5V/2A but only deliver a fraction of the amps. You can identify those chargers easily because they get extremly hot. I use a 2A charger from Aukey which gets only lukeworm.
