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

Alright, so I have a mini USB car charger that is rated at 2.0A (got with GPS) and I just want to make sure the extra amperage is not going to charge my battery too quickly and then kill it in the process. All I have to go on is that my wall charger is capable of only 1.0A and the computer USB is on the level of mA. Does anybody have a car charger or know the maximum amperage possible that these phones can take?
Thanks in advance.
Its to Strong ! I have Crash a PDA with 1.5A
I've used a 2.0a charger but noticed that the battery didn't charge right.
On that note, also noticed that a .5a or 500mA charger after about 6 months killed my battery. (burned out and won't take a full charge anymore)
Recommendation is to stick to 1.0A charging as much as possible as the Wizard's charge circuit is designed at 1.0A charging and monitoring.
DOESN'T MATTER ..if u know the basic Ohms Law..its the max capacity of the charger.(or any source) the current regulating circuits will take care of the real charging current fed to the battery
I charge my phone on my computers USB connection all the time, all computers have a maximum of 500mA USB current.
Amps are pulled from the charger, not pushed to the phone.
Voltages are pushed to the phone, not pulled from the charger.
If the phone draws too much current from the charger, the voltage drops to a point where the maximum power (P (Watt) = U (Voltage) * I (Amps)) of the charger isn't exceeded.
According to the USB specification you need at least 200mA with 500mA recommended +5VDC.
More is never a problem, you could even use a 50A power supply without breaking your phone. Practically spoken: I wouldn't do that.
huh?
I have messed up a few devices before by putting the wrong charger on the device (2.0 amp charger on a droid eris and 1amp charger on the MOTOACTV) Is this a problem with the device's charging circuit? In general it should only pull up what it needs to charge but my devices were messed up?
I returned the first MOTOACTV after it wouldn't leave the boot screen and the second one I got acted funny on 1 amps as well. It charged fine on .75amp charger that came with the device but when I put it on my HTC Dinc charger it shot up from 10% to 20 to 30 etc. all within minutes. Hope I didn't mess this one up too.
Just trying to figure out what the deal is. My phone for sure charges faster when connected to 1amp vs .5amp (computer). This makes sense I understand because the device is able to handle 1amp, but I wonder if it would mess up with a 2amp charger.
Thanks!
The last two posts of 2008 are correct. Your phone is capable of drawing more than 500 mA but less than 1000 mA. If the charger is 1A, 1.5A, 2A, or 50A, it won't make a difference to the phone's charging time or life.
Wrong voltage can be bad, but phones are designed to support USB charging, as a minimum, and 1A to 2A is always safe. As was said in 2008, the charger pushes voltage to the battery, but the battery pulls current from the charger.
That's a really good way of describing it
Pushing and pulling current and voltage is a really good way of describing it.. Given that I am theoretically well within the charging parameters, how comes my phone (Galaxy mini/pop) becomes unusable when its charging (touch screen doesnt touch and screen jumps to new screen without touching?) Am I wrecking my phone?
No, your charger is to blame. Maybe it isn't properly grounded. Phones with capacitive touch screens (not the Wizard! but maybe your phone) can get really weird on some chargers. I have a Nexus One with an aftermarket charger that always makes the touch screen go haywire. When I use an HTC charger, the phone has no problem. As far as I know, the damage isn't permanent, it's just that the sensors get confused. When I disconnect from the charger, turn the phone off, then turn it on, all is well.
My wizards were never bothered by chargers, no matter what kind, as long as they were mini-USB, they were the right voltage. The wizard doesn't take as much current as more modern phones, either.
Hmm. Not properly grounded sounds very plausible. Viva mediterranean circuits. Thanks
Usb chargers will be rated at 5v, which is exactly the correct voltage to charge your device. What you want to make sure is you buy the correct "rated" amperage. Not because it will damage your phone. Amperage only exists as a sum of the power used by the device. You want to find a decent 1amp (1000mA) or higher if you wish, rated usb charger. The the mains charger for your phone is only rated at 1amp, so a 1amp charger is adequate. Avoid 500ma chargers as it will take twice as long to charge and gps / satnav applications will drain the battery even when charging at that rate.
Also if you have a new pc, most of the decent boards will specify 1amp charge even when off if it has on/off charge stated on manufacture details.
Newer phones will charge fine with higher amperage
The myth that charging your device at a faster rate will reduce the life of your device’s battery is false!
If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts higher won't matter.... These lithium ion batteries can handle it... It was just back then if you were to try to put a faster charger in an older battery it (in any cases) just won't charge.
The stock charger from Samsung was for 0.7Amps and it charges ok, but I find it slow.. about ~4 hours to fully change my SGS2 from with less than 10% left of battery life.
If I plug into the laptop, it takes like ~6 hours due to the slow trickle charge with 0.5Amps.
I don't know what the max pull is allowed on this phone, but I did find that when I charge with a 1Amps charger, I can get it from less than 10% to full in about ~3hours.
So, I tried a few such charges and have noticed some strangeness.. (all with the same test conditions, start charging with less than 10% and with the stock usb cable for the phone)
1) older Belink ac-usb 1Amps out put, it does seem to charge the phone good and faster finishing around ~3 hours ... but, when charging, the touch sensitivity of the screen is out of whack, any subtle movement, will cause the screen to jump around.. like in gallery, trying to select an individual pic is difficult as the screen jumps around; forget about using the browser and selecting links...not sure why..
2) HTC thunderbolt charger 1Amps output (http://www.amazon.com/gp/product/B003WM6SOU).. same issue here, charges faster, but makes the screen jump around
3) iPhone charger 1Amps output; this seems to work the best for me so far.. charges faster ~3hours and while charging the screen behaves normally, I am able to use gallery and browser fine...
4) iPad 2 charger 5.1 V and 2.1Amps: Still charges the phone ~3 hours, but same side effect...
Anyone else have the screen sensitivity issue and what chargers are you using?
I haven't seen any issue when I used a HP TouchPad Charger rated at 2.0A I think..
Max pull is 650 mA - this is set by the charger chip itself.
If the phone thinks you have a normal USB connection to PC instead of a dumb charger, it will be 400 mA.
Having a charger rated more than this won't hurt, but it won't help.
Monoprice "1A" car chargers are rated 300-400 mA at best - the ONLY monoprice product I've ever been unhappy with in my life.
In general, you want to make sure USB D+ and D- are shorted together by the charger - this guarantees that the phone sees the charger as "dumb" and goes to 650. Exception are media and car docks - whatever you connect to these will be assumed by the phone to be a high current "dumb charger".
All phone power usage (CPU, screen, etc.) counts against this current budget - e.g. if you have 200 mA of load, only 450 will be going into the battery.
Unlike the I9100, we don't appear to have any way to change these charging currents. Our phone, for whatever reason, has an additional chip for charge control (MAX8922) instead of using the charge control built into the main power management chip (MAX8997). This is disappointing, I was really hoping to bring over the "charginghacks" modifications from my Infuse kernel series.
I have recently been profiling a few USB chargers to figure out which one is the best for rapidly charging my phone. A few threads have pointed to the EP851 charger being something a bit special. I was thinking about it on the drive into work..
The specs say that it charges for 60 minutes talk time in 10 minutes.
The XS has 8.5 hours talktime,
This means the charger can fully charge the phone in 8.5 * 10, 85 minutes
Plugging these values into my Charge Timer app gives an estimated power output of 1235ma, almost identical to the 1211ma of mu cheapo 1500ma charger.
Given this closeness, and the fact that the EP850 is also rated at 1500ma I am conclude that they are the same thing.
So, if you want a fast charger for your XS, and are waiting for the EP851, stop waiting and get a genuine BlackBerry Playbook 2A charger. It is about 10% faster (est 1314ma) and available now.

not updated with the estimated EP851 yet
That's throwing some serious power at the battery, is it safe? Will it knacker the battery faster? The PlayBook charger im referring to
Sent from my LT26i using xda premium
Is it possible that the S has the "boost" pin with its USB connector and the 51 triggers it?
This is my understanding of it. PIN 1 and 4 provide power, 2 and 3 provide data (and 5 provides USB OTG?)
If pin 2 and 3 are not bridged, the phone will charge at the maximum rate as determined safe by the usb 2.0 spec
If pin 2 and 3 are bridged the phone will charge at the maximum rate as determined safe by the phone designers.
Both scenarios are, of course, restricted by the power that the connection can supply. For example, if you plugged the phone into a 1000A charger, I would expect it to only pull about 6? amps
As for "is the Playbook charger is safe?", the Playbook has the same type of battery as the SXS, just a lot bigger. For the Playbook, this charger is considered the slow charger, and a rapid charger that pushes more amps at 12V is available.
Obviously, its your phone so use it how you want. I prefer mine in my pocket instead of tethered to a wall so I am going to use the fastest charger I can.
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?

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.
I have taken delivery of a Pipo W6s. It is a android/windows dual boot with stock rom as delivered.
There is a problem when attempting to charge. It runs while plugged in, but will not hold a charge. When plugged in it states 'plugged in, not charging'. i have tried several different chargers including the one it came with, and have the same problem with all.
Is this a hardware issue, or something that can easily be fixed?
I'd be grateful of any help, as I can't even seen to get it in to recovery (im a bit of a newb still!)
