Z3 Battery Charging Thread

Hiya,
I'm copying my original post over from the Z3 Compact forum as there should be a fair amount of similarities between the two models regarding battery charging.
Hiya,
I' hoping this is the right section to post this in.
I don't have my Z3C yet, but I've been searching for information on charging speed, charging current etc. - and there is barely anything to be found. What seems to be consent: A full charge (0-100%) takes about three hours. But then, some people say an almost full charge (0-90%) takes much less, as charging current is greatly reduced for the last 10% to reduce stress on the battery. Sony itself also claims that a small charge (something like 0-10%) should be quite fast as well.
Then there's some speculation about QuickCharge 2.0 being used or not used, that you could use a Motorola 2.0A charger to charge it faster than with the provided 1.5A Sony charger etc., which also brings up the question which resistor values on the D+ and D- wires are necessary to toggle different charging currents. (Or I might be stupid and there's a standard for that by now, which is the same for all Qualcomm devices.)
To cut it short: I'd request those who have a Z3C to post some comments about their charging times, and at best even their charging currents. I used an app called BatteryMonitor on my Desire HD, I'm sure there's others around now that give the same information. If someone could try out different chargers and record charging current over time, maybe even with a pretty graph, it'd surely help all future discussions about chargers, docks, modifications, DIY charging issues etc.

So, as the same goes for the Z3: If someone can record their charging times, charging current and charger used: Go ahead and post it. Bonus points for taking a look at magnetic charging.

A recent tear down confirms the Qualcomm chip for Quick Charge 2.0 support, so what we need now is for someone to get a compatible PSU that can 'talk' to the phone and then supply more power. That should see a huge improvement in charge time.
I am just trying to find a source for a compatible charger. So far I've only seen the Motorola Turbo Charger in the USA, and I'd be wary of buying anything made by a no-name brand at this point.
I have to assume the magnetic charging option won't be as fast, simply as there can't be a way for the PSU to know it is connected to a compatible device. Quick Charge 2.0 appears to require some sort of handshaking, or else the PSU will limit the power output, hence why I'd be wary of any chargers appearing on eBay or Amazon that claim to offer fast charging.

I have read excellent reviews for the Blackberry Premium Charger (the one with the yellow tip), super cheap on Amazon right now. Recommended by Android Central and others for its 2A charging capability. I have used it in the past from my HTC One X days and have re ordered for my Z3. Honestly, my Z3 is charging more than fast enough with the OEM supplied charger, which may be less powerful but more optimised than another OEM's charger. The one I'd trust most if I was forced to use one would be the above model of the BB charger.

more power can either be achieved through more voltage (that could potentially be harmful if the hardware is not compatible) or more current. More current is 100% save as the charging circuit just takes what it needs, independent of the (more potent) capabilities of the charger.
As Oppo showed with its find 7 just raising the current is a viable option which works. This is also a Snapdragon 801 device.

With the 1.5A original charger and cable, using Battery Monitor Widget shows the charging rate at around 900mA to 1000mA.
So I guess Z3 is restricting to max 1A charging?

Would it be possible that the PSU simply always limits the power output? For example, the phone might try to draw 1.5A, but the PSU doesn't support it and limits at 1.0A. Then magnetic charging could work with 1.5A or even 2.0A without the need for communication over the D+ / D- pins. (And attaching the magnetic port with a USB adapter to a PC or Laptop might cause the USB Port to shut down and trigger an overcurrent warning.)

That would make sense. Though wonder where the extra 500 mA are going, it surely can't be the phone's standby. And given a typical maximum charging current of 1.0C (C = battery capacity), it would translate into 3.1A of charging current and therefore a 3.5A power supply.
Is this current constant from 1% to about 65%?

If there are restrictions they are most likely within the Kernel and we may be able to change them in the future with custom Kernels

There is some fluctuation, but is roughly around 1A.

Thanks for the results. I have my Z3 by now and recorded some as well.
From 0 to 68%, it charges with 1000-1100 mA, then it goes into CV (constant voltage) mode and stays there until 95%. Then the curent drops slightly. The rest of the charging curve is not usable, as it was the first full charge my handset had. And the last for now, as I have to send it back due to a gap in the frame and microphone issues.
I'll post a complete curve when I have the new one and did a few cycles. What's clear for now:
1. Charging current with the stock charger is around 1.1 A max.
2. The phone charges up to 95% with 0.5% per minute. (Stock Charger)
3. It drops to 0.125% between 95% und 100%, likely to put less strain on the battery.
It's nice to see that there's appearantly support for higher charging currents. Though we should keep in mind that a higher current also means more stress for the battery, especailly when the phone is used while charging (higher battery temperature as the CPU also adds heat).

my Z3 came with the charging dock dk48.. it is rated at 1.8a, charging is fast

I can't speak to the Z3 (yet), but my Z1s charges nearly twice as fast on the magnetic charging dock as it does through the USB connection. As a result, I can leave my screen on at full brightness while on the dock and still charge. I would *expect* similar behaviour from the Z3.

Original charger: about 1.0A - 1.1A. Result: 3h 50p - 4h for fully charged.
Magnetic charging dock or cable: 1.5-1.6A. Spend only 2h 45p
I'm tesing Xiaomi MI Power Banki 10400mAh. First test: 1.6A, much faster than original charger. A bit surprise!

The original charger is rated 1.5A, actual charging on Z3 is 1.0A.
Xiaomi is rated 2.1A, so I guess is reasonable to expect 1.5A actual charging from it.
For your magnetic charging dock or cable, are you using the original charger?
With the original charger, I'm getting the same result with or without dock.

[Q] Charging

Hey all, haven't been able to find an answer for this. So I'll open a new thread. Now the question. The phone seems to take a long time to charge. Is it possible for me to use my Note 4's quick charger or can anyone recomend a faster charger for this phone? Charging it with Note 4's 2a charger wont damage the battery? Thank you.

I use a 2.1 out and it charges in about an hour and a half

Charging isn't fast and it seems that if the phone gets warm, it draws less power then too - so on a warm day, it can feel like it's taking years.
Would have been nice to have had wireless charging support and/or turbo charging, but alas not.

Doesn't the phone support quick charging? But Huawei haven't bundled the appropriate charger?

Doesn't appear to. I've got a Qualcomm Quick Charge 2.0 adapter and it doesn't seem any faster, nor say fast charging.

There's a quirk, when the battery shows 100% it actually still keep charging for another 30 minutes. All tests showed that it took 3hours+ to fully charge it. So quick charge my ass.

So just to update, I have tried charging it with note 4's fast charger and it charges the phone from 20 to 100% in about an hour and a half. Which imo isn't that bad. With the included charger, it took me around 2 and a half hours... Huawei really should have included a charger with higher amp, 1 is way to low.

It's sadly very common for phones to ship with poor chargers (1A and even lower), but then again - some phones these days come with NO charging adapter, assuming you'll have a ton of them anyway.
I use a 2.1A 5V charger, but I've tried the faster ones (that can output 9V) and it doesn't speed things up, so while it can charge faster with a better PSU, it won't ever charge as quick as many other flagships. Mind you, has the G4 been given full support yet? Likewise, the Z3 is down as supporting Quick Charge 2.0 on Qualcomm's website, but then turns out to be only some variants. Makes me wonder if the Z3+ supports it in every guise.
Not sure what the reasoning is for devices that could support faster charging not actually allowing it, especially if the manufacturer could profit from selling faster chargers separately.

I read an article about Huawei declining fast-charge for "battery-purposes" so it can have a longer life cycle. But i think Huawei made an exception about the Huawei Honor 7.
I had an Samsung before and never had problems with fast-charging whatsoever.
My P8 was full in about 2 hours with an 2.1 A charger, while my Samsung Galaxy Mega 6.3 took 1,5 hours.

the screenshoot took from Huawei P8 & P8 Max Launching Event 2015 said that p8 has quick charge at min 21.30 but they didnt talk about that in the event

Nexus 5X has Qualcomm SMB1358 Quick Charge 2.0 IC on logic board?

Hello,
I read in an article somewhere that the Nexus 5X has Qualcomm Quick Charge capabilities on the hardware side, but not on the software side. It also stated that this possible could be activated in the future. For the life of me I can not find the article now, but I did hop over to the tear down page that iFixit did on the Nexus 5X. Sure enough, the 5X does have the Quick Charge 2.0 chip on the logic board.
https://www.ifixit.com/Teardown/Nexus+5X+Teardown/51318
I'm not sure what this means exactly. Isn't USB C pretty much as fast / faster than QC 2.0? Or, would QC 2.0 via USB C be even faster?

This phone will never see qc. Google is all about open standards which is why it has usbc and can charge at 3amps.
Sent from my Nexus 5X using Tapatalk

God can people just stop with quickcharge?
The device is charging at 15W at max allready, and thats just for a short while. The majority of time charging is spent under 10W (2A).
QC is not magic and wont make a difference for N5X. My M8 with QC and the same battery capacity charges nearly identicaly as to my N5X (same battery capacity), it just goes 9v for a shorter while but the total wattage never goes above 15w for QC charger.

I feel like the desire for qualcomm quick charge is so that people can use the wall plugs and car chargers they already own because the adapters that actually support the usb c standard are few and far between or really expensive from Google, it's not about which one is better or faster.
Sent from my Nexus 5X

That chip is a power management IC with QC features, does not mean LG/Google even hooked up the wires required to use it or put in the additional components that might be nessasary to make it work. I don't think Qualcomm publicly releases data sheets so we can't know but I doubt the hardware as a whole supports it.

In case anyone is interested. I have a Quick Charge 2.0 certified car charger and it works with my 5X. It enables "Charging rapidly". Same thing with my Note 4 rapid charger. Both work fine.

Hove you looked at the actual charging rate at all? Just because "charging rapidly" does not mean it is truly charging as fast as it should.

I'm gonna answer this even though I don't appreciate your tone. So I'm doing it for the benefit of others. Yes it does charge at a fast rate with all three chargers (stock, Samsung Fast Charger, and QC 2.0 charger). About 1-3% per min and it slows down, as it should, when above 80%.
And "Charging rapidly" wouldn't get triggered if the power management charging circuitry didn't detect that the charger had the proper dynamic output voltages/currents, with the power output being P(t)=V(t)*I(t). Your "rapid charger" will have two pairs of output ratings for current and voltage (some have 3).

I'm not trying to be mean and I did not intend to have a negative tone so I'm sorry for that, I just wanted to see the actual numbers when using that charger you mentioned and see how they compare to the OEM charger because from what I have read charging rapidly is faster than normal but has a very wide range that can trigger at much lower charging speeds than the OEM charger.
Sent from my Nexus 5X

All of my testing on "charging rapidly" indicates that the phone is charging at 2.1A, not QC 2.0.
I suspect most QC 2.0 chargers offer 2.1A charging for when an iPad is connected, to prevent the user from returning the charger because it didn't charge their iPad. Google probably exploited that by simply telling the Nexus 5X to accept the iPad 2.1A handshake, which doesn't require QC 2.0 to be enabled.
It is possible QC 2.0 is just disabled in the baseband, but considering the backlash that Google got... I suspect they would have at least committed to enabling it, if that were an option.

That makes sense thank you

Fast charging with 2A charger

Hi
I am planning to buy this phone.
Can anybody confirm if faster charging is possible with a 2A non stock charger? How much time does it take to reach 100 percent?

For me, it takes 1h 30m to charge from 0% to 100%

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...
Sent from my iPhone using Tapatalk

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

This is the 3rd comment I have seen from a user confirming 1A is the max phone can utilise

Yes, you have right.
We can put a 10 A capability charger at our device, but charge control circuit is doing his job and let device charging with 1 A max, even if is there 10 A disposable....
Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).

There just isn't enough development going on for this phone for anyone to discover and share such information

Above review was found by another user on this forum where it's mentioned that phone supports 10W (5V×2A)
So this is what I am hoping is correct and is verified by someone who owns the phone already

Maybe fast charge working with another type of charger: Huawei 9V2A Quick Charge Travel Charger
Instead of 5V1A(5W) or 5V2A(10W) with 9V2A(18W) charger, the charge circuit control will sense 9V instead of 5V and maybe switch to fast charge...

2 Amp charger are only needed if you are using a 2 or 3 meter USB wire.

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

Great that you actually measured it, I am assuming using an external device...
That would confirm it without doubt that online reports are incorrect and phone can't charge above appx 1A

yes that is correct

So just a quick question.
This means that for a phone to be able to pull 2A, is not just software control?
It means that the hardware has to support the ability?

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.

Use QC3.0 everyday?

What do you guys think about it?
Is is "safe"?
What Chargers are you guys using?
thanks in advance!

I've read that G6 does not support QC3.0 for now but it's about to thanks to the incoming update.
But anyway, of course, why not!
I did so with my Xperia Z3 Compact which supported QC2.0 but it's pretty much the same case for our G6's. I never had any problems with the battery in my Z3C.
I'm also planning to buy QC3.0 charger, which one are you gonna use?

Well, i'm using the default charger, which is supposedly qc 2, but qc 3 shouldn't damage your battery in any way. It charges very quickly to around 85% and then slows down to preserve battery life.

first time i hear that
it says here:
http://www.lg.com/in/lgg6#specs/specifications
and here:
https://geizhals.de/lg-electronics-g6-h870-schwarz-a1584137.html
also in several yt video tests that it clearly can do QC3.
i use that charger:

yep the included one can QC2 (asked LG support about it)
and ive read the same thing about qc3... that it is supposably battery "friendlier", thats why i was wondering what other lgg6 users do

I've confirmed that the charger that came with my G6 is QC3.0 (model MCS-H06UR, UK 3-pin). Using a USB power meter, the voltage will increase from 5V to 9V in small steps. If I use a QC 2.0 charger (stock charger from Note4/S7edge), it will jump from 5V to 9V immediately.

Now, this is interesting and good to know. But QC 3.0 has two components to it. One is the variable voltage, but the second is actually using voltages up to 22V. So it would seem that this is QC 2.5

Well, it just means that it can support up to 22V but not that all charger must support 22V to be QC 3.0 compatible. If you look around most QC 3.0 chargers only support up to 12V.
