Fast(er) AC Charger Recommendations

Greetings! I was wondering what is the maximum rated input current of the Xperia Z. There's no indication of it's rated input current anywhere on the phone. The supplied charger is rated at 1.5A and I was wondering if a higher amperage charger above 5V 1.5A (such as of those catered to tablets/ipad) would charge the battery at a faster rate before investing in one.
Anyone with any experience using a higher amperage charger on the Z could advice on any notable improvements in charging time as well.
Thanks!

Used a Nexus 7 charger rated at 2A and it charged fine with no detrimental effects. Charging time is about 1.5, hours from 10% to full.

While increasing the Amps will result into fast charging... the bad part is that it kills your battery life overall.

I've tried Sony charger rated output 1500mA
and Galaxy tab charger 2A
phone on, screen off
in 10 minutes charge, both added , just the same, 10% juice.
may try it longer next time.

Would you care to explain?

Great findings! I guess it's safe to say that there is no notable reduction in charging times even with the provision of higher amperage chargers, and that the Xperia Z's power management IC can only take in 1500mA at max.

Charging at higher amperage would generate more heat and this increase in heat would degrade the battery cells at an increased rate, thus reducing the lifetime of the battery in the long run
Well unless you value your charging time (or loss of usable time) more than the cost of premature replacement of battery, then quick charging is for you. Personally, given a choice, I'd rather not charge at a higher current unless necessary, especially when time is the essence. (;

I will post when I find the correct link.

Erm I'm fairly sure that whatever amp you use the phone will only draw a set amount I used a 2500mah charger with my old phone for two years no difference in charging time nor degraded battery life or iverheating , just meant I had one charger for everything lol

That's correct, it's impossible to over-charge or charge too quickly a device by using a charger with a higher current rating than the original charger. Current flow is a RESULTING property of a particular voltage applied across a particular resistance. Applying too much voltage will usually be detrimental, but you cannot SUPPLY too much current. The device will draw as much as it needs unless it is limited by the charger's maximum current rating first.
I've been using an old Blackberry charger rated at much less than 1000mA. It might take a bit longer to charge, but I love the long, supple lead that comes with it.

Can someone explain me this...
My Xperia Z came with (1) Power plug-adapter with USB port + (2) USB to Micro-USB cable + (3) Docking station.
The (1) has Output = 1500 mA written on it, the (3) has 1800 mA on it.
Questions:
Can the USB cable transfer more than 500 mA? From reading USB page on Wiki, looks like it can do 1500 mA - 5000 mA when not transferring data so I should not worry about the cable?
What is the point of including a 1800 mA docking station + 1500 mA power plug? Does the station only charge at 1500 mA when connected with that plug or am I missing something?
Thanks, sorry for noob questions

The charging chip it self support higher current by default, but the manufacturer chooses the charger depending on different factors, design of the phone, capacity of the battery and also their stock chargers available... they will choose the best charger to match... in most cases it will be rated lower than what the charging chip is capable of...
the charging chip has it's limits also... using regular USB cables will only provides the standard current... I've used same amperage chargers as the orignal but with different cable and charging was slower... when I switched to the original cable charging was faster and had the same time as original charger ( same amperage )
When you use the original cable and higher current charger then you will have faster charging...
My Xperia arc came with socket charger rated at 950mA and a car charger rated at 1200mA... and the car charger is really faster but only when I use the original cable, when I used a longer cheap cable the charging was actually slower... even when I'm charging non-Sony devices ( like my Note 2 ) when I use original cable ( wether Samsung or Sony one ) charging is always faster... I don't know why it might be a way to protect the standard usb cable from over-current as the standard USB current is 500mA, so the charger will normally send the usual current unless the device requested higher current then it will negotiate with the charger to send higher current the original cables might have something like impedance between some pins so the phone will detect them as original then they will negotiate the charger to send higher current or the charger might actually use the other pins to send higher current but the phone will only use these pins when it detect the original cable... if not then it will not use these pins and will have regular 500mA charging... I've always faced this when dealing with other cables... now when I want longer cable I just use USB extension cable with the original cable and it will work !

- Yes, the cable can easily transfer more than 500mah. No worries.
- It means the docking station is rated for a maximum of 1800mah - so if you buy a 2100mah charger, the docking station may get warm and if it fails Sony won't cover it under warranty. If you use the 1500mah power plug, then the docking station supplies the 1500mah - it's just a pass-through. The docking station itself doesn't really have additional circuitry.

Can now make some docks/charging clips using sugru and a usb cable
Not sure why the dock would be rated at 1800, unless they've fitted it with some circuitry, a simple micro usb to prongs would do.
I charge mine using the adapter that came with my note tablet which is 2a and also with the 2a output of an external battery pack.

Yes, they're right to write the 1.8A there.
because, not all microUSB survive to deliver more than an amps. They maybe melt. especially the cheap one that have very small and loose contact area.
the pogo pins too... Not so easy deliver 1.8A with pogo pins...
that's why intel processor, have 1000+ pins, but almost 300pins are for power supply only (GND and VCC). Although the chip is only 1.25volts, but the current sometimes about a hundred amps (Core 2 Extreme, Core i7)

Wrong. If you connect a 2.1A supply, you'll see no difference.
Charging rate is set by the phone, as long as the power supply feeding it doesn't "brown out" under the load.
2.1A, 3.1A - doesn't matter, the phone will draw less (I'll need to drain my battery down a bit to determine how much less, it's often less than whatever the wall charger is rated.)
There is a possibility that when it sees voltage on the pogo pin connectors, it increases charge current to a different value than on AC via the USB port. The ext charger handling in the pm8921 driver is really convoluted and difficult to read.

samsung galaxy s5 charging time. 2.0(micro usb) 3.0 cable

hello members.
i posted this thread as i dint found any comparision time for chargin between 2 diffrent cables. 2.0 vs 3.0
i found the same charging time on both 2.0(regular micro usb) vs 3.0
it seems 3.0 only helps for very fast data transfers..
(hope this info is useful

Yup.. There will be no difference in charging time as there are no power pins in the extra Usb 3 lines.

I use USB 3.0 cables and it is much faster for both, charging and data transfer.

Download galaxy charging lite from the play store and check the incoming current. It's the same for microusb 2.0 & 3.0.
Maximum of 1800, usually charges at 1200 w/ screen on.
If you claim that charging is faster with the multipurpose cable, show screenshots.

I have both s5 and note3, tested with both USB 2.0 and USB 3.0 charger. It's just same output, time or charging current. Transfer speed, I didn't know because my PC not have USB 3.0 port

fffft said:
Your conclusion is misleading. You probably won't find a difference between USB 2 & 3 if you are using data cables as your phone limits it's draw to about 0.5A to protect lower specd USB ports.
If you want faster charging and in particular, take advantage of the higher current that is available from AC adapters or many newer USB 2/3 ports, then you need to use a charging cable. This is not the same as a data (multipurpose) cable. A charging cable has the data lines shorted to tell the phone that you are connected to a high current or at least protected source and it should go ahead and draw as much current as it can use (or is available if the port is current limited, but protected).
Of course, it should go without saying that if you use a power cable with a conventional USB 2 port, you are circumventing the safety protection and may damage your USB port.

This is interesting, my phone will recognize my (2 amp) AC charger as AC, yet with data cable it'll only go 550 ma according to that app (450 if recognized as USB). If I switch to a charging cable it'll take 1.2 amp from the same charger. Strange logic.

Well maybe its just me but my phone actually DOES seem to charge faster with the new 3.0. Like a lot faster.
Maybe it is "placebo" as you say but for me it really is faster. Just my 2cents.

the cable doesnt make any difference its the charger that needs to be higher

It's the charger that should be shorting out the data lines, not the cable. I would think that a cable that did this would pose a risk that, if inadvertently used to connect a phone to a regular USB port instead of a charger, could cause the phone to think it can draw more power than the port can safely provide, and subsequently overload and damage the USB hub.
Whereas a charger that shorts out the data lines can be used with any standard USB cable.
Maximum power ratings are a different matter, though. AFAIK, standard USB 2.0 connectors only need to be rated at 1.5A current to be compliant, but charging ports and cables (i.e. those compliant with the Battery Charging Specification) need to be rated to handle at least 5A - although, this is in spite of the maximum draw of 1.5A anyway.

with USB 3.0 and standard charger reached battery from 12 percent to 92 about 80 min
I've heard about 20% charging difference and I think it's true

This is about what I get with my supplied wall charger and cable. Its nice being able to use the phone and still get a charge at the same time. My Nexus 5 would only maintain a charge level and not gain any charge when being used.
One day last week I forgot my spare battery and had to use my mini USB cable I have at work connected to my computer and it took most of the day to go from 15% to full charge. The S5 has the best battery life out of any phone I've had so far but I wish they would release 4.4.4 for us as I saw a noticeable improvement in battery life with my Nexus 5 when i put 4.4.4 on it.

USB 3.0 Charging
So as most of you have come to realize, there is no difference in the basic way that USB 2.0 to USB 3.0 cables carry current to the device. The extra pins in a 3.0 cable are for full duplex, (bi-directional data transfer) at really fast speeds, up to 4 GB/s.
USB output is rated at 5V. The output current from different brand computers might reach 600ma. The current is regulated to avoid overheating the cable and computer power supply. The extra twisted pair of wire in a USB 3.0 cable enable a bit more current handling... up to 900ma.
The reason your newer Samsung charges the device faster is that the new power adapter (mine is white) has a current output of 2.0 Amps. The older power adapters had a rated output of 750ma, 3/4 of an amp. Result.. The new power adapter system facilitates fast charging.
I'm guessing that they spec'd the higher output charger to match the higher power usage profiles of the latest Samsung Galaxy products. I remain a fan of slow to medium charging rates to preserve the life and charge cycles of the battery. High rates yield more heat which can shorten the life of the cell structure.
Hope this explanation helps.

Take heed of this response - it's the most useful one here. There is no difference between charging via a usb 2 and usb 3 cable as long as both are decent quality (recommended 23awg gauge minimum for 2amps).
The extra usb 3 pins don't carry any additional power wires.
Ensure you're using good quality cables as mentioned above - look for 23awg (gauge of the wires within the cable) printed on the cable (all original and genuine Samsung cables are rated at this) and a 2A charger (again, recommended to use original and genuine Samsung charger) and there will be absolutely no difference between usb 2 and 3 cables.

usb 3 charges faster.
Those who say that usb 2 needs the same time as usb 3 don't know what they are talking about.
I won't talk or pretend that I know a lot about tech but here are some real results that doesn't come out of my head.
Usb 2 cables max amp is 450mha and I have tried 3 different cables a Motorola ,my HTC one X and a plain usb 2 cable that I have .All 3 of them gets 400 or 450 mha.
But when I use the original Samsung usb 3 ,a cheap China usb 3 or my black usb 3 from my external drive the Samsung let's 1800 mha to pass by.
All test are done with the original Samsung charger and a cheap 5 dollar one which I don't use much because when the phone is not charging it makes a weird sound.
And the only way what I say is not true is that my s5 detects the kind of usb I have and limits the charge which in result is the same thing.

There is no limit and this guy has no idea what he's talking about. There are no extra power wires in the usb cable - in both a usb2 & usb3 cables there is a positive and negative wire which provides power to the device period.
FYI, voltage and amps are 2 completely separate measurements which only compounds the stupidity of his response...

can you please check with Ampere or GSAM for the charging speeds that you achieve?
does the device say fast/rapid charging?

Interested to hear the results from Ampere or GSAM as well

i cant get a good handle on how ampere works. it keeps measuring, takes forever, and fluctuates a lot.
with the aukey combo, i got 1830/2050mA @ 4.14v, at 53%, 37.7c
took it off charge for a while and tried again with the stock charger:
with the stock charger, i got 1850/1860mA(min/max) @ 4.159Vat 61%, 30.7c
I will try again at 50% today if I have time but I am pretty pleased with my little aukey combo. It was cheap.. I got it when there was a 7 dollar coupon floating around.

The voltage - current output test show that the voltage stay in the 9.0V range with current up to 2.4Amp then fall down very quickly. It seems that the voltage stay at a value enough to deliver up to 3.0 Amp charging current to the tablet ....

LOL, thanks... but that doesn't really help this 5X cause. Given that there is no quick charge on the 5X, it'll remain at 5V. The question is whether it'll pull more than the 2A or 2.4A specified on these chargers at 5V on a 5X.

Aukey quick charge 2.0 behave like a standard charger when connected to a non QC2.0 compatible device. The output voltage will stay to 5V so the current level will be very sensitive to the quality of the USB cable and limited by the maximum current the device will afford.
In practice it is very difficult to reach 2A charging level ( even if the charger is able to deliver such current) with a voltage output of only 5V , due to losses in cables and connectors
From my experience the higher current charging level I obtained was with a Samsung wall charger refence EP-TA10EWE which deliver an output voltage of up to 5.5V at 1.9A ( nominal voltage is claimed at 5.3V)
I got 1.7Amp charging current on my Nexus 5 while with the Aukey QC2.0 the current was only 1.1 Amp in exactly same conditions ( these recorded data are also reported in my blog .....in French.....)

Thanks, didn't think to look at the link.
I wonder how older phones like the NA Galaxy S3 and Nexus 4 that both have QC1.0 ([email protected]) compare to the charging of the Nexus 5.
I'm curious as to how you did your testing, as I'm going to try my own testing once my cables come in. Did you drain all your phone's battery to 0 before performing each test? Phone airplane mode vs off? I also think that all tests must be done in relation to time, especially since the charging profile changes as the phone charges. I'm also curious as to how the non QC port on the Aukey performs, since it's spec'd at 2.4A @ 5V.

All tests are made with battery drained to zero before starting , and a complete charge is done in each conditions. That way I can check that the full charging time is logically related to the recorded current values. The current is recorded during the complete cycle at a frequency of one value per mn.
The air plane mode was off.
Aukey QC port and non QC port are slighly differents when connected to non QC2.0 devices :
QC port delivers 5.1V in open circuit, the voltage encrease to 5.2V at 2.2Amp, on the contrary the non QC port delivers 5.2V in open circuit and decrease to 5.1V at 2.2Amp. I did not test them at higher current level.
I did not tested Galxy S3 or Nexus4 , but I beleive that a charger like the Samsung EP-TA10EWE will deliver them the maximum charging current they are programmed to accept, as obeserved for the Nexus 5.
I got the same charging current curve I recorded with Nexus 5 and Samsung EP-TA10EWE, with other set of charger and cable. This means that this charging curve is defined by the Nexus 5 inner program , not the charger characteristics. The problem is that we never know which is the max current curve internally programmed for each smartphone...... so it could be a long way to find it.......

Confirmed fast charging longer cables?

Those who have their phone know the cable on the fast charger is 1 meter, which is not long enough to reach any table youd ever have a plug next to.
I tried two different type C -> Type C cables and neither would fast charge with the included wall wart.
Anyone find a longer cable that fast charges with our plugs? 2 meters would be great.

It's tough sledding hacking through all the different Amazon.com listings to get something with an actual USB 3.1 and 3A rating for a 2m cable. The ones I;ve seen are either out of stock, take forever to come from China or overpriced in the $25-30 range. Would love to hear from anyone that actually found one too.

I bought a type C to A from amazon for the computer and it charges rapidly on all my wall chargers down to 2.4 amp.
Monoprice was out, otherwise I would have ordered there. >>> http://www.monoprice.com/product?p_id=13010
this is what I'm using, fast charges and mounts no problem.

I would bet this will work. same brand as what I have, they have a real thick jacket on them. It's a good cord.
http://tinyurl.com/oyahw4h amazon link
edit, I just read the description on amazon for those cords
....Note for Nexus 5X/6P: In order to ensure FAST CHARGING, please ensure the charger can output 5V/3A. The cable can afford 3A current did not mean it can provide 3A. We recommend use Google official USB Type C charger with our USB C to C cable...

That monoprice page is goofy.. title lists it as USB 2.0 and then the description goes on to talk about USB 3.1

Monoprice 2.0 six foot c to c cable charges just as fast as the 3 foot cable that came with the phone. High quality stuff. The phone doesn't support higher than 2.0 anyway.

USB 2.0 refers to the data transmission standard and really nothing to do with charging amps. Although, to be USB 3.1 compliant, I think the cable needs to be fairly stout to handle the increased loads in both data speed and charging power. My guess is this cable is in fact 3.1, but someone made a mistake updating the title.

I understand that. Monoprice's 2.0 c to c cable supports up to 3A. No point in spending almost double the price on the 3.1 cable..

What I am saying is that it is hard to even trust the 3A rating with the conflicting statements on 2.0 vs 3.1. Do you have the cable and have tested it? That would be different.

Yes I do have the cable. Monoprice has that 3.1 description on all of their type c cables for some reason. The 2.0 3a cable works just fine.. I just went from 49% to 82% from when I went outside to winterize my boat and when I just went back in to check my phone, not sure how long that was, but a pretty short period of time. I usually put it on the charger when I turn on the TV at night and take it off when it hits 100% before I do to sleep.

I ordered this USB A to C one, http://.ebay.com/itm/261840366171 . The phone says Charging Rapidly. I have not done any data transfer with the computer, but upon plugging it in, the computer detected it ok. It ships from the US, but took a little while with standard shipping. Maybe almost a week;

just got some usb-c to usb-a 3.1 cables from techmatte this coupled with my Insignia 5v 2.4a charger from best buy are giving me a "rapidly charging" icon on lock screen

It might say rapidly charging but I doubt it's as fast as the stock charger. I've used a USB-A to type C cable, got rapidly charging, but it was only max 1800 mAh as opposed to the 2800+ with the stock one.

You're right but its still faster than not rapidly charging

I dunno about that. I have used a couple 2A Samsung USB chargers with type a to c cable and my phone charges almost as quickly as the stock charger at least in regards of empty to full. I think the difference between the stock and alternate high amp chargers that are around 2A is how quickly it can do a partial quick charge from say 0 to 50% but from 0 to 100% I haven't noticed much of a difference.

I got one of his cables to review... I got it to charge 2.2A + using a 2.4A charger. But I do think you are correct in that there probably isnt a 3A option with anything using USB TYPE-A. 3A seems to be the realm of pure USB TYPE-C.

I purchased this cable and it charges at the same rate as the short OEM cable supplied with the 5x.

Thanks but unfortunately i got it and it didnt work, it just says charging with the stock charger. That sucks because otherwise its a great length and a really nice cable, guess I will have to return it.

That's really odd. Mine registered fast charging immediately. I tested with Ampere multiple times and received the exact same reading with both cables.

Does the Mix ship with a 3.0 fast charger?

This is something i haven't seen mentioned or confirmed in all the reviews i have read. I have read reviews of other xiaomi devices that said it was qc 3.0 enabled, but the charger that ships with the phone is not a quick charger and the user would have to buy their own to take advantage of this feature.
so does anyone know if the charger we receive with the mix is in fact a quick charger as the mi mix is on the devices that is qualcomm quick charge 3.0 enabled.

Check features: http://www.gsmarena.com/xiaomi_mi_mix-8400.php

That site quoted 83% in 30mins, I am not getting that, not even close. I bought the anker USB C quick charge charger which suppose to be quick. I don't feel quick at all...
Anyone also bought charger that can comment on this?

yes, as i posted i am well aware the phone is quick charge 3.0 capable. my question though is the charger that ships with the phone a quick charge charger. there are other xiaomi phones that are also quick charge but the user has to provide their own quick charger.
if i were to guess i do not think this charger is a quick charger based on my results compared to my nexus 6.

I got an Aukey QC3 5-Port Charger.
I'm trying to get my device empty right now (tough though as it lasts pretty long) and will test it afterwards.
Gesendet von meinem MIX mit Tapatalk

I compared the included charger with my Anker quick charge 3 charger using the Ampere app.
The given stats were marginally better with the included charger.
I'm not really sure what all the figures mean but they were there or there abouts the same, the Anker charger is Qualcom QC3 certified.
Not nearly getting the quoted charge times though with either charger.
At 53% it claimed 44 mins to 100%

Yes, it ships with a fast charger. It delivers:
5V - 2.5A (12,5W)
9V - 2A (18W)
12V - 1.5A (18W)
So yes, it's a QC2.0 fast charger.

I'm currently at 69% and on the normal charger it's 3 hours+, on the QC2.0 charger I have, it's 1.5 hours and it gave me the same for the included charger. Kind of disappointed that it's only 2.0.

after seeing how insane the battery life is on this phone i just went with the qi wireless charging usb C adapter and I have no plans on going back, works awesome.

What I dislike, and you can't use is the Wireless Charging with your phone and case, and a metal plate stuck to the back of the phone. You see, I really like the various magnetic holders in the car (I have one that works with the CD Slot of the vehicle to mount the holder, another that is a little ball mount that sticks to any flat service). They use a thin metal plate to mount to the back of the phone case, and the magnetic is part of the phone mount that is in the vehicle. If you place the phone with the holder and the metal plate on the wireless charger base, it will overheat both the charging base and the phone.
I REALLY like the magnetic phone mount, and do like wireless charging but it a moot point if you have a mounting plate on the back of your phone or case.
I am using amperage and I own two qualcom version 2.0 chargers one from my Nexus 6, and one I bought on amazon. The OEM Nexus 6 draws about 1.6amps on charge, and the Anker 2.0 draws under 300 mAH. The computer 3.0 USB port from a desktop draws 370mAH to charge the phone.
I will probably invest in a true oem qualcom 3.0 charger.
Pretty cheap of Shomi to not include a 3.0 charger

I'm revising my previous post, it seems that the provided charger may indeed be a QC 3.0.
I've been reading that if you use USB-c to USB-c cable instead of the provided USB-a to USB-c cable, you actually get charge rate.
I've also been reading up on the QC 3.0 vs 2.0. Both will max out at 18watts. But 3.0 has a variable voltage whereas 2.0 is fixed at 5V, 9V and 12V. You can see that in the below link, there's a nice table of Watts for each QC.
http://www.androidauthority.com/quick-charge-3-0-explained-643053/
However with USB-C to USB-C, it can charge at full 29Watts. That's a huge difference.
you can see that in the description provided by Anker here
https://www.amazon.com/Anker-Type-C-Delivery-Charger-PowerPort/dp/B01D8C6ULO
You can also see here in this device
https://www.amazon.com/Lumsing-Charge-Charger-Foldable-Macbook/dp/B01I1OIO4A
it says 48W of power, and allocates 19W for QC 3.0 which means the other Type-C port is allocated for 29Watts.
So I think I'm going to be looking for something with a direct USB-C port as a charger.
Certainly, this may be all for not if the Xiaomi Mi Mix is limited to 18W of input anyways.

I have the Anker USB-C to USB-C charger, my initial testing indicate that the original charger (China Plug) and my Samsung Galaxy S6 Edge charger (UK Plug) are capable of doing 23.8 Watts max, i tried to monitor the difference and what I noticed is the Mi Mix original charger seems to be adjusting the charging power more often (not really sure why and whether it's good). My Anker USB-C to USB-C went up to 28.9 Watts Max. All chargers seems to scale down their charging rate after battery reach 80%+ so I think the best way to test is to empty the better and start from 0%. I doubt I will be doing that test though as it's quite hard to empty battery on Mix and I am pretty happy with my Anker charger so don't think I will be using Stock one or my Samsung one.
Unless I go on holiday with multiple devices that still use old USB port, Anker USB-C to USB-C is my go to charger.

So I think what you confirmed was that the mix can take power at 29 watts.
That's good to know.

Just received this wireless charging receiver today that claims to do fast charge
https://www.amazon.com/gp/product/B01LX0Y5CS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
it does charge much faster, almost double of the one i posted originally in this thread. i'm getting a charge on it around 950ma which isn't too bad for wireless i don't think.

Is there an app I can use to see if this phone is quick charging ? I have a Google pixel charger USB c to USB c. Trying that out now .I can't really judge because this phone is at least 1000 mAh bigger than what I'm used to lol.
