[Q] Does the Xperia SL have Quick Charge 1.0?

We know that the Xperia SL charges faster than the S, is it due to the new Qualcomm Quick Charge 1.0 feature or is there another technology behind it?

yes. super fast charging )
i see if you've unlocked the bootloader and you'll root it. you'll be amazed! haha

who this "we" that know that Xperia SL charges faster than the S? i mean.. where did u get that information? i dont know that. S and SL is almost identical (if i cant say they're the same). so, i think they charge the same. btw, my XS charges fast. about 1 hour 20 minutes from below 5% to 100%.
and i think it's not because Qualcomm Quick Charger (which i think just marketing gimmick), and beside Qualcomm just got it in June 2012.. xs comes in february 2012. afaik it's just one the kernel (driver) of XS. it can take input more than 1000 mA. EP850 (1500 mA) gives XS about 1200 mA, compared to other phones (using same charger) usually got below 1000 mA.

You are so informative on these things :good:
And how do you get just 1 hour 20 mins? Mine (Xperia SL) slooows down charging that could take from 90% to 100% in 30 mins
I'm using blackberry charger at the moment that gives ~1400mA (according to charger timer app)

Not exactly, the Xperia SL came out later in the summer so it could very well have Quick Charge. I doubt it's a marketing gimmick if Qualcomm is actually giving out a press release that lists multiple manufacturers. There are some significant differences in between S and SL.

yet Qualcomm (in that page) didnt say that SL has it. yes, maybe it's not a marketing gimmick, but i just dont see how it's work, and no explanation given. my thought is it just the same as Sony's (when <80%, it gives more current) and/or their devices can get more than >1000 mA -> if using charger rated more than 1000 mA, both are old news, and Sony has it in their phones. i mean, u cant make magic that make the charger gives more current more than it rated (eg: 1000 mA charger gives 1100 mA -> what kind of sorcery is this? ). . If you want to charge a battery faster, you just gotta (1) make sure it can charge faster (greater current) without overheating and (2) deliver greater current to it -> XS/XSL (and some other Sony phones already capable both of em )
really? what are the significant differences between S and SL? afaik, there are 2 differences: 1. bluetooth -> xs has 2.1, xsl has 3.0 (gsmarena write this, dont ask me) -> but users here in xda said there are no noticeable speed difference between two, some even says that the bluetooth in xsl give same lag too when using with bluetooth hands-free (same as xs) 2. the xsl processor gives 1.7 gHz -> xs can easily achieve this with custom kernel. and thats it. xsl can use xs rom and kernel without any problem. so..

quick charge 2.0 is not enabled

So I tried a Motorola turbo charger which has QC2.0 capability on my HTC one m8.
Got a full charge in 2hrs 10 min.
That sums it up, we don't have the technology enabled to save the battery from deteriorating.
I'm on stock UK Rom.
Cheers.

The question is how fast did it get to 70% from dead, the charger slows down as it gets closer and closer to full.....

Here are some screen shots. Tells you how fast it was charging.

Sounds the same as the stock charger. The phone will only draw as much current as it's made to draw. More powerful chargers won't change that. ?

Yeah, people said it supports qc1.0 but it is not.

HTC has yet to enable quick change 2.0 on stock roms, so unless you install a custom Rom/kernel you won't see any difference over the stock charger. And I'm not even convinced that they don't need a firmware update too.

Update
It seems to work if battery temperature is 35 ℃ or less. I was gaining two percent per minute when battery was cold. Could be just thermal efficiency though.

TurboPower 30 NOT charging faster than Turbopower 15. What's going on?

Hello all,
The recent discussions on xda and r/rMoto_Z about battery chargers and questions concerning whether or not a TurboPower 30 charger is it worth it to us Z Play users prompted me to do a quick test comparing the chargers.
What I found is my TurboPower 30 is not charging any faster than the TurboPower 15 that came with the phone. I am using tasker (I'm a tasker noob BTW) to log the time and battery level to a Google Sheet upon a change in battery level. I discharged the phone to 14% both times, shut it down, let it cool, turned it on, then plugged in without touching it during the charging process.
Overall, both chargers behave the same. Both charge at a rate around 1.1% to 1.15% charge per minute until the 90-92% mark, where they slow down drastically.
The TP15 took 90 minutes to charge, while the TP30 took 95 minutes to charge.
So what's going on here?
Is my phone malfunctioning?
Is my charger(s) malfunctioning?
Am I stupid and/or missing something?
Can the Z Play even make use of the extra amperage from the TP30?
I'm at a loss here. I could have sworn the TP30 seemed faster, but maybe not.
Can anybody else confirm the same behavior from their chargers?
I can provide a link to a graph and the google sheet itself once I get past the 10 posts required before posting outside links.

I have the Z Play and the Z Force. Using the 30 watt charger on the Play still only charges it at about the same rate as the 15 watt charger. Not sure of the reasons just saying the results I have gotten.

Motorola probably put a limit on that

Charging from 30% to 50% took just a few minutes but phone got really really hot... I'll stick to charging with my 10w ipad adaptor... Decently fast and phone stays cool :good:

TurboPower 30 i guarantee only reaches 30 watt output over 12 volts. Our phone only accepts 5v at 3 amps max (you can force it, but you will probably ruin a component). This is due to thermal restrictions and to help preserve the battery from degrading faster than normal due to heat. With my moto x pure I recieved a turbopower 25 which charged my phone (which is about the same size as this one) at 12v ~2.1 Amps and the phone was already thermal throttling while charging. With a phone that lasts 2 days already Lenovo probably figures you can top your phone off when you have time to, and even then charging at 15 watts is still pretty quick if you really need to charge your phone in a hurry. More power going in = more heat put out due to inefficiencies. This will change whenever we get superconductors figured out and can have ~100% efficiency, but that will (probably) take a while, and even then take longer before it trickles down to consumer products.

Actually, the TurboPower 30's max output is 5v @ 5.7a, hence the large fixed cable.
Motorola lists the TurboPower 30 as compatible with all Moto Z devices. I took "compatible" as meaning I will receive the full output on a Z Play. If that's not the case, then Motorola should specify as such. I mainly just want to find out if my issue is by design or isolated to me.

Surprising that its actually at 5 volts tbh, since manufacturers were moving to 5, 9, and 12 volt standards for quick charging (not sure why the higher voltage instead of higher amperage). It would be by design though as the thermal restrictions still stand. The phone would have a hard time disipating all the heat generated (unless you suspended it by a string in mid air and had a fan blow on it :laugh and it could degrade the battery faster (due to heat). It is technically compatible in that will charge the phone and quick charge it at 15 watts, but it will not go up to 30 watts. It could be useful in the future when more laptops have thunderbolt 3 or 4 ports and you could use it for that .

So what specifically in the design of the Z Play creates thermal restrictions greater than that of the Z Force? And what makes you believe the TurboForce 30 charger will charge other devices at ~30w? Is it a USB Power Delivery spec charger?
Regardless of all this, I still find the product description disingenuous. I would have simply gone with a standard (and cheaper) 15w USB-C- charger had I known this.

It is disingenuous to an extent, they didnt lie to you when they said it would work, but they just didnt tell you that it wouldnt charge at the full 30 watts (maybe there was an asterisk for it?). From the little bits of research I did on the moto Z force forum, it seems that it does follow USB-PD, but I dont know much about USB-PD specs or Qualcomm quick charge specs honestly. The only real advantage the Z force has in terms of helping with heat disipation is the aluminum backplate it has vs our glass backplate, it could also have some extra copper inside of it to help spread the heat around as well. Aluminum transfers heat better then glass does which allows it to have more wiggle room in terms of thermal restrictions, but I bet you the phone still gets really hot while turbo charging especially at 30 watts. Since it seems to follow USB-PD spec that would mean that if another device that follows that spec (a laptop with USB type-c thunderbolt 3?) and requests that much power then yes, it should work.

and then, what is the exact charger for Moto Z2 Force ? 15 (included in package), or 30 ?

What is the correct way of charging the moto z play?

Hello,
I am new to the moto z play. I had the moto x style before.
Can anyone tell me the best / correct way of charging the moto z play?
I've read sometimes that charging to 80% and using the battery to 20% and recharging would be the best way.
But when I do so, I have to charge my phone almost every day.
Is it possible to charge the phone to 100% or 90%?
Excuse my bad english, I am from germany.
Best wishes,
a new user to the moto z play

Just charge it when it need to be charged lol
There isn't magic tricks to charge it, and obviously you can charge the phone to 100%

Charging a lithium battery to a lower voltage can increase the overall cell cycle life at the expense of capacity. At 4.2v you may get 300-500 full cycles before you start seeing noticable degradation where at 4.1v you may get 600-1000. But the effort to track that and stop charging I think is negated by the fact this phone has such high capacity vs it's usage that even if it's degradated - you will still have a good run time!
With that being said - with root or a custom ROM - you may be able to set a lower charge termination voltage like on some Sony phones had an option for - but I don't know the details of how to do that.

For more info check: http://batteryuniversity.com/index.php/learn/article/charging_lithium_ion_batteries
I almost always charge from PC/laptop using regular USB port which can provide up to 500 mA. Usually when I see that is getting close to 40%. And often not charging over 80 but that depends do I need the phone for longer period or just forgot to disconnect. Fast charging in general is not healthy for battery, mainly because of heat produced.
On another hand, most probably battery life is longer than phone's. Just because phones are getting obsolete...

Sony Xperia XA1 not quick charging

My new Xperia XA1 (G3121) is not quick charging using the original UCH12. I installed the ampere app to check. And the UCH12 doesn't charge any faster over the stock charger.
What's even stranger, is that I already had this UCH12 with my previous phone, the Xperia Z5C, and it did use the quickcharge capabilities.
I took my old Z5C back out of storage and tested both devices with the ampere app. The Z5C was allowing a whopping 3850 mamp! Whilst the XA1 doesn't come any further then just under 1000mamps. The voltage also doesn't get lifted over 4v.
Is there some kind of hidden setting that I need to toggle?? I was under the impression that the XA1 does support the QC2.0. What am I doing wrong?

Hi
I think that you've programs that battery drain on background

Nope, it's the same with all background apps closed. Even when it's turned off it charges in the same time with the UCH12 and UCH20.

I think it's because of an update, because it's the same for me now... ?

Just chiming in here, I just got the phone and updated to the latest November patch. The phone only seems to charge properly and quick charge when the phone is turned off. Looks like the problem is software related (at least my problem).
When it's turned on, the phone seems to charge a little bit then drain. Which is confusing at best.

Are you sure you have genuine original UCH12? There are a lot of fake UCH12s on the market. All logos and labels are almost the same. I hit one fake UCH12 charger. It was supposed to be an OEM without original package.
SONY logo is written in different font. On the back in tiny letters is written brand "Sany" made in "Iapan". Very difficult to notice the difference. What more, this kind of charger supports QC3.0, but not PumpExpress2.0 which is supported by XA1.
How can you see charging voltage in Ampere app? I though it is not supported by software.
(I used this fake charger only for few minutes. Maybe it was enough to damage touchscreen)
