Hi all!
I charged my Xperia Neo with another cable (the one from Kindle reader) and it actually charged it up much faster than with the stock one. I used the official transformer only with a different cable.
I've noticed that with the official set my phone charges aproximately at half the current than with others. So, I get it to charge at around 500mA with original and around 900mA with others (max. current as it depends on SOC - State Of Charge).
Is it any bad for the battery? How bad?
Actually, other devices such as Nexus7 charge at this current. And I believe they all have similar battery technologies.
It is safe, its like using a slow charger and a fast charger concept. The downside is the battery will reach its wear and tear and lessen its life.

It would lessen its life anyways since the battery needs to be charged, wouldn't it? Does it really matter to charge it at a higher current (around 1A)?
I'm no expert on this issue so I think that if Sony designed the transformer and the cable in that way there must be a reason.
Also I noticed that the heat from the battery produced during charging is higher.
- With original transformer/cable: 28ºC peak.
- With original transformer and a different cable: 38ºC peak.
Actually, I think that even wtih 3D games it doesn't reach that temperature.
Last time my phone was charging at higher current and i was doing a phone call it restarted after a while. Not sure if it was due to temperature though, but it might not have been the reason since my phone reached 41ºC before and no reboots have happened.
Somebody knows what range of temperature should this phone work with? I mean, not to provoke a reboot nor to damage the hardware.
I usually use and HTC one that is 1A at 5v and my neo is perfect... for example Samsung give you also a 1A at 5v Charger
That's what I wonder.
If all phone batteries are similar in the technology they use, why Sony provided a cable that reduces the charging current?

I have four chargers that follow the same basic design, plug-in socket at one end, USB port at the other so you have to use the USB-data cable to charge the phone. I have one for my son's Sony Xperia Go, my ASUS Transformer Infinity tablet, my old HTC Wildfire and my even older Sony Ericsson Xperia X1i... what I'm wondering is that since they all use the USB standard, could they be interchanged without damaging the battery of the phone/tablet? Can one assume that the voltages and currents and everything (I'm no electrical guru obviously) are the same? Oh and I do actually own a SGS2 but that uses a different kind of charger anyway so it's irrelevant really...
Should be the same.

Regarding the voltage one can assume that a charger with an USB port always will supply a voltage of 5 volts.
However the wattage of the chargers will differ. This is not really an issue as the charging current is basically controlled by the capabilities of the device to be charged (your phone) and not by the capabilities of the charger. This holds true as long as the charger is able to keep up with the current requirements of the device. This too is generally not a problem at all.
When it comes to the time it takes to charge a device, things can differ quite much.
Assuming you do not have a kernel like for example Siyah installed (and tweaked charging settings) your phone will set the charging current according to what it detects on the USB port. If it detects a standard USB port (Laptop for example) it will charge with a lower current. If it detects a dedicated charging device it will draw much more current and the charging will hence take less time. This detection (USB port or dedicated charing device) depends on the impedance between the two data lines D+ and D- of the USB cable. A dedicated charging device will have a low impedance or to put it simple: a charger should have a short between D+ and D- to be detected as such. This short is part of the charger not part of the USB cable (this allows you to charge the phone with any standard USB cable).
At any time you can use Settings > About Phone > Status to check the Battery Status. If it shows Charging (USB) then a standard USB port has been detected and charging will take more time. If however it shows Charging (AC) then a dedicated charger has been detected and charging will take less time.
Last but not least you might experience one more difference between the chargers: the amount of noise (ripple on the 5V DC) they generate. The less the better. The ripple on some chargers is that bad that the touch screen will be absolutely unresponsive during charging. The original Samsung and many other chargers are fine, but I have some low cost models here that make using the touch screen during charging impossible.
Generally I would answer your question like this: yes, chargers with USB connectors are interchangeable. However the charging result might differ quite much.
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.
Cheers.

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...

The Sony CPF2LS USB Portable Power Supply with 7000 mAh Battery charges at 1.5 amps so it should work for you. I'd post a link to Amazon, but, alas, I can't. It's around 63 bucks.

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.

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 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?

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).

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.
I bought my Pipo w6s 3 days ago and could not find much information nor links to firmware/OS for this tablet. Are there any active owners of a Pipo W6S with or without 3G at XDA?
Presently I am looking into reducing the charging time wodering if the supplied 5V 2.5A Power supply and cable is just to weak to charge/operate at the same time and if a new PS USB cable may improve the situation?[/B]
When I bought my w6s 3 days ago, a shops display model, the battery was also completely empty. Assuming that idle operation may take somewhere from 5 to 10W, this does not provide sufficient energy to operate the tablet and charge it at the same time. I learned this when I waited at the shop, while they downloaded and installed the english language pack for windows for me. Even though the w6s was on the charger for nearly an hour at just 25% brightness it still showed 0% of charge. Back at the hotel I charged the w6s, while it was turned of and it worked, but required several hours.
The battery is about 6A at 3,7 V hence 22 Wh, the power supply is 5V at 2,5 A hence 12.5 W, which allows operation, but not, if any charging is done at all, much charging. I read somewhere charging may take 6 to 7h, so the batteries do not seem to allow for fast charging and would be charged at just about 1A.
Can anyone please check the voltage of your power supply, is it just 5V or higher?
I found that while my Samsung Note 3 on the supplied power supply which has 5.4 V charges faster than on those just having 5V. When operated in the car using a 5V output PS, the Note 3 operating as GPS using sygic never charges, so I assume a PS with a slighly higher Voltage that is within the tolerances of USB may improve charging time. Another variable should be the resistance of the USB cable used, the thinner the cable/higher the resistance the lower the voltage at the w6s input. Since my PS broke on the airplane and the shop did not give me the USB cable I cannot check the manufacterer values.
Anyone any active owner? Do you have any thoughts/information?
PS. did your W6s come with any Trojans/viruses or such unpleasant things?
Hi I have these model also.
My tablet comes with 50% battery. I think the main problem for me is tree the low battery and the little support that I find for these model. I have a charger of my t100 and the tablet charges ok
