Yes can we charge our tabket with mini usb port, with a blackberry charger?
No, we can't.
What would happen if I charge it with blackberry charger
Nothing ... there is no connection to the battery ... so it will not charge.
That just is poor design. Sony controls the power connector deliberately making it proprietary. Its expensive and bulky to bring around. Further more its battery life is nothing to shout about. Making this problem even more glaring. Its not as if the competition are not implementing micro USB charging.
I hope the Sony design engineers are able to do something about it. Good design doesn't just restrict itself to external physical aesthetics.
The problem here is that the AC adapter output are 10.5V and USB is limited to 5V.
But I agree, I wonder if Sony will ever learn that the use of proprietary accessories and ports is NOT a) customer friendly and b) not driving up sales numbers.
They (more or less) failed with their Memory Sticks, they failed with UMD and they will definitely not create a hype around the PS Vita with it's proprietary memory card.
BackToTopic:
It is not only the voltage ... a second topic is the current.
USB can only provide 500mA current .. but this would lead to a quadruple charging time.
Also, you'd be surprised how many tablets can't charge from USB. Since USB uch low voltage and current limitations, many tablets don't charge or implementation iPad-style behaviour (doesn't charge but also doesn't discharge). There will always be something about the Tablet you don't like, so just enjoy what is overall a very good Tablet.
So long as future iterations of the Sony tablet charging port is not proprietary that will be good enough I guess. Its mind boggling the rationale for going to a totally different and unique design.
They could standardize the mobile smart phone charging ports why can't they do it for the tablet?

They can't do it for the tablet because all the tablets on the market today work on very different power requirements to phones.
On one level, different tablets use different approaches to batteries (i.e. the Thrive is a very large, user-replaceable battery, whereas the Sony uses a smaller, hard-to-remove battery pack), which would make them difficult to standardise.
The other problem is different power requirements. Tablets often operate on much higher voltages than phones, such as the Sony's 10V battery which well exceeds the 5V that USB can provide.
I'm sure one day there will be a higher voltage standard connector, but at the moment, the market is just too varied and too fast-moving to support the creation of such a standard.
The Apple iPad charger has a 2100mA which is more than 4 times what standard USB chargers output, many other tablets have a similar output. It would still be longer to charge than the standard plugpack. Unfortunately, Sony seems to view Apple's success, as an argument for using proprietary accessories and cables. But newer Xperia devices are shipping with Qi Wireless Charging; in a generation most devices will most likely use that.
Hi,
I've always found the battery in this phone to be poor.
I've owned years of Xperias and only one other had a bad battery life (Sola). This very often won't reach 1 day even on half brightness. I don't use this phone any more than the last one, or the one before, so it's the phone not my usage.
I just asked Sony and it doesn't use Quick Charge 2.0. That explains it. It charges so slowly.
The stock charger pumps out 850mAh. I see some chargers pumping out 1500mAh. What would happen to our phone? Would it charge even a little bit faster? Is it a threat to the phone's health?
Thanks
i charge my sony m4 with lg charger 1.8 A output, my phone charge much faster
Nice to hear!
Is that 1800 mAh? Input or output?
Thanks!
It shouldn't really damage phone I'm using 2.1mAh output charger on my current phone Lg L7 II while waiting for new phone (M4 Aqua) and it charges really fast, lasts long and no problems so far
Nice to hear it, guys. I sent an email to Sony and they answered that it supports 1500 mA so I bought(ordered) EP880 charger today. After trying it I will tell you how it works.
Thanks guys!
This is more like it! The M4 section has lots of views in threads but few replies! If we drop a line or two we can really learn from each other like this.
1500 definitely works eh? I chatted with a Sony rep and they said Quick Charge 2.0 is not supported in the phone. Not much info. from them. But I will look for the 1500 charger. That would be great.
2100? Wow! I wonder if your LG phone supports Quick Charge 2.0?
Interesting thread:
I found this interesting Sony Mobile thread where a Sony rep tells us a bit about it: https://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/needed-help-with-charger-for-xperia-z/td-p/373667
My first instinct was to browse on eBay. I'm going to get one there. Watch out though! There are many non-Sony chargers and some of them don't look trustworthy. Also, many of them say output 5.0V. But at which speed? 850 mAh or 1500 mAh? Some say 5.0V=850 mAh and others say 5.0V=1500 mAh. So, if you don't shop carefully, you may get the 850 charger all over again!
UCH10 Charger
As another comparisson, the standard (and only) quick charger available on Sony Mobile for any phone is this one UCH10:
http://www.sonymobile.com/global-en/products/accessories/quick-charger-uch10/specifications/#tabs
Output
5V/1800mA(9W)
9V/1700mA(15.3W)
12V/1275mA(15.3W)
Support Qualcomm's Quick Charge 2.0 Class A
"Maybe I'll try that charger? It can't do any damage according to Sony Mobile:
There's really no recommended mA from what i can find. The phone will use the amount it can handle up to a certain level. The fact that a charger is specified to a high mA doesn't mean that it's "pushing" that into the phone. It's what it can deliver."
https://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/needed-help-with-charger-for-xperia-z/td-p/373667
BUT...I checked Qualcomm's compatible device list, there are some Sony Xperia devices but the Z5 series mostly, not the M4. So, it would charge the phone but at a much slower rate...1500 maybe? But not Quick Charge 2.0 speed. So the older EP880 charger of 1500 mAh seems to be the max for this chipset/device.

1,800 mAh, that's the same as the Sony Quick Charge 2.0 UCH10. That's definitely 1,800 mAh? I just don't want to spend €27 on discovering that I made an error and it's not compatible!
P.s. I've bought the EP880 1,500 charger and tested it, you can read here.

Well I don't know really Qualcomm page says that snapdragon 200 supports QuickCharge 2.0. Yet I don't have any issues with it. It takes around 1hour 10mins to charge from 4% to 100% 2450mAh battery
Just to point out that in my research Qualcomms "Quick Charge" uses a higher voltage output while you're not using your phone.
These chargers are "smart" in that they communicate with the phones chip to give the OK on fast charging. If they don't they'll stick to universal 5v output.
You can buy other aftermarket "fast chargers" and these only output 5v but at higher amps. I use a 4.2amp charger for all my devices, my M4 takes about 50 minutes from 10-100%.
Also note that devices generally will only draw what they need/want. If a device only requires 1 amp and you use a 2+amp charger, it will only draw 1 amp.

Hi, thanks for the info.
You may have seen that we're confused about the M4's capabilities. Sony says it cannot support Quick Charge 2.0. Qualcomm lists that chip (in some, not all, I noticed) pages on their site as supporting Quick Charge 2.0. Do you know if it does?
I'm new to learning about devices drawing power. Would you mind giving a brief run down on what the M4 can draw in terms of power, what the stock charger draws? Then we could see better what a 4.2amp does.
Please and thanks!
I can confirm that several different QC2.0 chargers charge the M4 Aqua NO FASTER than a capable 2.1/2.4A charger. While the Snapdragon 615 chipset supports QC2.0, there is other circuitry in the charging path that must support it as well and Sony chose not to implement it in the M4 Aqua.

the difference is generally in the kernel
for example, the lg g2 mini has an SD 400 that supports QC 1.0 and is not functional in the stock rom, but with modded kernel that feature was enabled and the phone charges faster with a 2A charger

Can you point to an example for QC2.0? For 2.0, the charging circuitry must be able to sense and adjust voltage and current draw from 5v to 12v with steps in between. QC 1.0 is Qualcomm's implementation/branding traditional 5v/2A charging. Also, QC 2.0 circuitry can be licensed and implemented in other SOCs as is evidenced by the ZenPhone 2 (Intel) and Galaxy S6 (Exynos).
You're right that QC2.0 can be implemented at the Kernel level IF the underlying circuitry is already there (as was the case with the SD800 powered LG G2). That said, if the supporting circuitry is not there (independent of the SOC) it can't just be enabled in software.
It appears that this tablet is finicky when it comes to charging. Fast chargers give it a slower current than slow chargers do.
Anybody else noticing that?
It's not intended to use Qualcomm quick charge, no support for it. You'll see faster performance with chargers intended for iPads or say they're 'smart'. They'll detect the preferred power requirements and allow the maximum charge speed. Also keep in mind the quality of the USB wire will affect charge speed as well.
I have the same issue. Although the tablet doesnt support Qualcomm QC, it should still be backwards compatible and be able to put out a high current. I've used my QC charger with other non QC devices and it charges them all quickly. However with this device, it charges extremely slowly.
I think the issue is on the device side. Whatever method it is using to detect the type of charger that is plugged in clearly does not work very well and it is self-limiting the amount of current it wants to draw. Like when it thinks its plugged into a computer USB port.
As for the cable, I've used with with several other devices so I don't think it is the issue.
Now years ago, I seem to recall that many phones will look at the data lines. If they are shorted or open (can't remember) then it assumes it is not connect to a computer USB port and therefore it is ok to draw full current. So people started selling "charge only" usb cables. These days with all the various quick charge capabilities, I think the data lines are used to communicate low level information to configure the quick charge. Maybe this tablet is still using the old method and getting confused by the more advanced chargers.
Can anyone confirm if these chargers are compatible with the rog 2? Planning on getting one.

It is interesting, but at the same time risky, if they are not compatible they can shorten the life over time, damage the battery indicating false reading on the phone, or the last thing burn you'r phone.
I would really like some hard info abou this topic!

Thankfully due to USB standards, plugging your phone into a charger that is capable of outputting more power than the phone is designed to use, will not damage the phone as it is not the charger that decides the speed that the phone will charge at, it is negotiated between the two devices and charging will start at the fastest speed that both of the devices support.
Due to Oppo's VOOC 2.0 being a proprietary standard that is only supported by select Oppo devices, if you connect any other device to the charger, it will just charge at whatever the maximum speed that can be negotiated between the two devices, which is most likely going to be 5V 2A (10W).

So since oppo owns realme it's probably using the same proprietary tech too. Bummer.
The question is whether you REALLY need those extra minutes shaved off of your charging time. Faster the charging, faster your battery deteriorates. Speaking of compatibility, I doubt you'll get anything above the 30W that Asus provides support for. I'd recommend you stick to the 18W/30W charger bundled inside, or a QC 4.0 charger.
Works fine with my old Huawei Superchargers (45W)

How faster is it compared to the stock charger?
What fast charging technologies does the phone support? Heard on the Internet that he supports power delivery, but I couldn't get it to work. Maybe some kind of Magisk module is needed or the phone still only supports vooc?
