The actual threshold for switching from CC to CV charging is around 80% in my experience.

I suggest using CurrentWidget which will show you a graph of voltage, state of charge, and current into the battery over time.

With a 2.1A Samsung charger and a 1.5 foot 24-gauge USB cable, the Z3 charges at 1.2-1.5A into the battery when the screen is off. (Cap is 1.5A). Samsung tablet chargers are the best you'll get from a non-QC2.0 charger since they actually boost voltage slightly under load (up to around 5.3 volts at 2A) to compensate for cabling losses.

With a QC2.0 charger and pretty much any cable (even a very thin 3-footer) - it will cap the battery at 1.5A, and will usually cap it even with screen on.

TL;DR - Cable quality (resistive losses due to length or wire gauge) is EXTREMELY important with regular chargers (you need the absolute best of the best to hit the 1.5A cap), cable quality is removed as a factor by QC2.0 except for the absolute worst of the worst.
[Xperia Z3 Accessories] RockStar2005:
I dunno about the voltage entropy, I just am focused on the time spent charging and what results from it.

So is double the speed of USB 1.0/magnetic charging good enough to qualify for QC 2.0 status?? Or do other phones charge even faster?? Anyone else know?? I think doing over double what USB 1.0/magnetic charging can do is pretty amazing. I even went ahead and just bought a new QC 2.0 car charger as well to complement my home charger.

[Xperia Z3 Accessories] RockStar2005:
Most obvious example is Google Maps Navigation in daylight. With most non-QC2.0 chargers, the battery drains. With QC2.0, it charges at a reasonable rate.

Entropy,

Yeah you must be right about Google Maps because I've noticed that with my old regular charger when I use Maps with GPS on, all it does is charge the phone enough to stay at the same percentage............ it never goes up! That didn't used to happen before though, so I guess the consumption requirements of at least Google Maps (if not the phones themselves) has gone up. With my MPow charger, it still does charge to increasing numbers, but I'm gonna be selling that cuz I just got the Aukey QC 2.0 one I mentioned before (just came in from Amazon today).

RockStar2005
[Xperia Z3 Accessories] Entropy512:
Google Maps has always been a power hog. Whether it exceeds the capabilities of the charger depends on:

1) The phone. Larger displays use more power of course, and most modern CPUs use higher peak power than older ones. Navigation is bad about using whatever resources it can get even though it really doesn't need them. It really should have a framerate limiter or something so that modern CPUs get limited to lower frequencies, but it doesn't appear to

2) The cabling. With a 3-foot 24-gauge Monoprice USB cable, I could usually charge most phones very slowly when running Nav. When using a StarTech right-angle cable (really needed for Xperias due to that stupid side USB connector), I'd get battery drain with most devices until I switched to a QC2.0 charger.
[Xperia Z3 Accessories] RockStar2005:
Entropy,

That is all very interesting information, and not so surprising either. Perhaps that is why all these faster chargers are suddenly emerging out of nowhere. No one really tells you when you're buying your new phone that the older chargers may not make the cut the way they used to in the past. You just have to learn that on your own.

I think that by having a QC 2.0 wall and car charger, plus the Z3's Stamina Mode being activated, we're AHEAD of the curve compared to other phones. lol :cool::good:

[Xperia Z3 Accessories] abhinav.tella:
How is the heat? I too have an Aukley charger for my dad's M8 but have been to afraid to try it on the Z3 as sometimes it gets uncomfortably hot while charging, with nothing more than web surfing going on, just using the normal charger.
[Xperia Z3 Accessories] RockStar2005:
Hey abhinav............. what's up? How ya been?

Which Aukey charger of mine are you referring to? The wall charger or the car charger?

When using the wall one, I can't say I've noticed any issues with my Z3 being hot. That only seemed to happen when Stamina mode went haywire and I had to factory reset my phone to fix it (clearing Stamina Mode app's data & cache usually works, but when it doesn't, a factory reset ((preferably using Sony PC Companion)) and then a re-enabling of Stamina mode is a must). The battery drain would be crazy and the phone would get warm all the time no matter what. I SUSPECT that enabling/disabling Stamina mode too many times once it's set may be the cause of it eventually going haywire, so I don't do that anymore, and have even removed it from my navigation pane to avoid accidental disabling.

I JUST got the car charger yesterday, so haven't had a chance to test it out yet. Probably will tomorrow or by this weekend for sure.

I can't say I know why it's doing that with just the regular charger. How has the battery been on your Z3? Do you use Stamina mode? If it seems like it's been draining faster than usual (even with Stamina mode enabled), then you may need to do what I said above. Let me know and I can give more details for you to follow.

The M8 is a great phone. I just love Sony a LIL more than I do HTC, or else I would've kept MY M8 last year for sure. lol If Sony didn't sell Xperia Z phones though, I'd def go back to HTC. My sister just got the M9 this past Sat (upgraded from Samsung Galaxy S4), and I helped her configure it. The camera still isn't fantastic, but I think it's getting better. Other than that, it's very similar to the Xperia Z phones in many ways if you ask me.

Thanks, but the answers linked are based on theory. I don't mean to be step on your toes, but just by reading online that "every Z3 variant has supported QC2.0" does not convince me enough. I believe in testing and getting actual results to prove whether it supports the claim. I have conducted many experiments with various chargers including the QC2.0 chargers/cables, and in my experiments, I charge a full 1% to 100%. My results show that the charge time is not an improvement at all compared to standard USB cable, magnetic charger, etc. (See my experiment thread for details). If QC2.0 works as it should on the D6603, I would expect faster charge times, correct? I am getting 160 minutes charge time on a full charge with QC2.0. The Samsung Galaxy S6 charges within 70 minutes with QC2.0 (link). The idea that QC2.0 charges at a different rate (faster) while the phone screen is on is absurd--not saying it is not true, but it is ridiculously impractical to do daily.

I haven't gotten around to buying one, but I guess one way to test is to get a QC2.0 charger that indicates HVDCP status as mentioned in your earlier posts.
[Xperia Z3 Accessories] Entropy512:
No, not theory. Reality. Seriously, even after I linked to it, you obviously didn't read post 63. Or (I admit I didn't link them, I shouldn't have to) posts 68 or 72.

And I NEVER said it charges faster when the screen is on. I said that the difference is MORE NOTICEABLE when the screen is on. Specifically, turning the screen on will result in a major reduction in charge rate with a standard charger but NONE with a QC2.0 charger. Especially if you run Google Maps Navigation - The Z3 with a standard charger will often not even be able to retain charge despite external power with a normal 2A charger, but charges AND navigates simultaneously with QC2.0

Since the Z3's battery is nonremovable, Sony is far more conservative about peak charge rates, which is why normal 2A chargers can come close (but not quite) to the cap.

Install CurrentWidget

Charge to full using a normal charger with CW's logging enabled - you will notice the device frequently drops below the 1.5A cap even if the screen is off and never anywhere close to 1.5A if the screen is on. This is even with a 1.5 foot 24AWG cable and a Samsung tablet charger, which is about the best you're going to do since the Samsung tablet chargers increase voltage slightly under load to compensate for cable losses.

Discharge your device, then charge to full using a QC2.0 charger. Observe that the entire time, even if the screen is on, it charges at 1.5A.
[Xperia Z3 Accessories] MoreYummy:
Who has the detail how the chargers works, since those charger all capable to output, but they didnt output at their max. Its more like software used in phone to draw more power.
[Xperia Z3 Accessories] clockcycle:
I have a Zerolemon 18w USB Quick Charger http://www.amazon.com/dp/B00WM93M9S was sent to me for review using with my Nexus 6. i've been testing on my z3 and z3v.

It tends to "rapid charge" up to 1250 mA. Using a 2A samsung charger they tend to charge anywhere between 650-990 mA, much like using a standard 1A charger.

By comparison the Zerolemon charges the N6 at 2200+ mA.

Tested using the Ampere app in play store.

I also noticed something interesting, the z3 drops from consuming 380 mA to 150 mA, while the z3v idles at 370-380 mA viewing the app screen on.

hi, i just bought HTC Rapid Charger which support QC 2.0 today and trying to make a comparisson between this one and the z3's :o

and here are the result :)

oops forgot to tell that my unit is D6653 :D
[Xperia Z3 Accessories] MoreYummy:
So your htc quick charger can do better than original z3+ charger?
[Xperia Z3 Accessories] kaframaster:
you mean quick charge UCH10? :confused:

I just bought that one also, and got the same result :)

[IMG="UCH10"]http://s18.postimg.org/3np77f3q1/Screenshot_2015_07_06_19_04_41.png[/IMG]

my question is, did the QC 2.0 really work? should it be at least 2A right?
[Xperia Z3 Accessories] MoreYummy:
yes, im talking about quick charger, since you bough them right? So 2 quick charger has different output....
[Xperia Z3 Accessories] DandroidT:
As an end user, I am more interest in end result and I am disappointed with the charging speed of Z3 T-Mobile variant D6616.

So according to Qualcomm website, Z3 is supported QC2.0 but I tried different qc2.0 chargers (Motorola turbo charger, Samsung note 4 adaptive fast charger, and Verizon generic qc2.0 charger) but the max speed I saw is 1.5A (using battery monitor app).

QC2.0 supported or not, if Sony capped the charging input at 1.5A, then that is not "quick charge". I can charge the galaxy s4 quicker at 2.0A and same for LG G2 at 2.0A and they are not qc2.0 support devices.

My note 4 can charge at 2.9A, nexus 6 can charge at 2.6A, droid turbo can charge at 2.6A and it is notable faster than the Z3.

Hi guyz! now I have a 0.30 mm thick tempered glass and works perfectly with dot view case...

I just ordered a better one which is 0,33 mm and I'm not sure it works....

does anyone have a 0.33 glass which works with the case
[One (M8) Accessories] Chris_c81:
I'm surprised your 0.30 mm one works well with it. The best ones to go for are the 0.15 mm ones to be safe.
[One (M8) Accessories] throcker:
lol really? never had problems with 0.3 ones....for everyone's information it works great....
[One (M8) Accessories] henderjr:
I have a .33mm that didn't fit well at all with an OEM dot view case but fits great with my knockoff (http://www.ebay.com/itm/291190318285)
[One (M8) Accessories] throcker:
thank you for your answer, I was looking for this, exactly. so double tap works? device locks well when you close the flip? I know that is not fully closed, but I don't care about it :)
[One (M8) Accessories] henderjr:
Yep it works just fine. I like it better than the OEM even when I didn't have a glass protector. The OEM version is too springy and hard to hold open. This "knockoff" has more of a hinge and easily lays flat when folding it to the back and it's not near as springy. It does close by itself though but not as snappy as the OEM.
[One (M8) Accessories] throcker:
well, ok, I have a knockoff too (very well made, it has also all htc signs) and I'm about to order the OEM one......should I do it? If you have the oem black one, can you tell me if is really black or grey?
[One (M8) Accessories] henderjr:
My OEM was grey. I broke it trying to stretch the cover to fit over my glass protector. Basically ripped the front off the back. Whoops. It's the same grey color as my knockoff. My knockoff does not have an HTC logo on it. Your call on how the case will fit and if you'll like it. Maybe see if a local sprint/verizon/att/t-mobile store has them in stock so you can look at or maybe even try on your phone?

For me I like my generic dot view case much more than the OEM. Though I can't do a real comparison since I ripped it apart and finally threw it away a couple days ago.
[One (M8) Accessories] throcker:
lol here in italy att, tmo, vzw and sprint are like american dreams....nothing like that here, htc are unknown phones (Here people think that samsung created android) and while you can find every type of cover for s5/note3 and even the old pop touch samsung, htc cases are impossible to find. so I have to buy online and risk.

and...back to thread, I don't know if I should put the 0.33 glass instead of the 0.3 I have now......

and if I can ask a suggestion, I'm looking for an open back cover (a bumper borderline would be perfect, but the aluminum one [I have 2 of em] doesn't protect the back.....so i throw them away)
[One (M8) Accessories] throcker:
ok, for anyone info, dot view works perfectly with 0.33 tampered glass, which is I think the highest working thickness
[One (M8) Accessories] scott500:
Anyone have a link for the knock off they are buying that works ok with a .30+ glass? I got two different knock off's from ebay and neither of them close properly with the iLoome glass screen protector. One I got is a generic and the other is a HTC clone (with logos etc).

Dear XDA Members,

My P765 now is on Bootloop, it wont load the OS. Before it happened, the phone was fine with CM 10.2 and CWM Custom. I try to flash again an TWRP which can only use to flash CM 11 Unofficial. After i flash the recovery, it went normal. I restarted the phone, and the phone was working. I copy the CM 11 then i try to flash it by entering the recovery again, but the method just open the fastboot page, not the TWRP. and now the phone bootloop on LG logo. I try hard restart, and it couldnt work. i try to flash again the KDZ but the KDZ updater said my phone not recognized. Does anyone knows what should i do to fix my phone? :crying: Thanks before.

BR,

If you can manage to get into fastboot and flash uboot and xloader, then connect the phone on software upgrade mode, it should connect. Although there is a catch, THIS WILL RELOCK YOUR BOOTLOADER.

[Upgrading, Modifying and Unlocking] thallanor:
I have been a member here for the past few weeks and have been excited at the progress made with the latest AKU updates. The problem is that I can only understand what the updates do. I understand what the AKU is, but am confused by a lot of things.

First, I own a UTStarcom 6700. (HTC Apache, I believe?) My carrier is TELUS Mobility in Canada. My biggest fear is bricking my mobile. I understand that I am supposed to install the latest AKU in Bootloader mode. If I mess up an update, or the update just doesn't work with the mobile -- or even if it does work and I want to go back -- can I go into Bootloader mode again and install the last OFFICIAL firmware update to go back to AKU 2.2? There is an update process here on TELUS' web site. Because my mobile came with the latest firmware, I didn't need to do this. But for those more in the know, does that page I just linked detail what I would essentially need to do to go back to the last official firmware?

That out of the way, what exactly is required to update the firmware to add AKU 3.3 support? I have seen a few .exe files floating around, and I am wondering if they are generic? I have seen a couple that indicate they are for the HTC Apache, but are they generic to that mobile, or tailored for Sprint, Verizon, etc.? I'm afraid of crapping something out on my mobile because the firmware adds some features for Sprint, or lacks some features for TELUS. (Things I am worried about are #777 for DUN, that sort of thing, and other carrier features or details.)

That brings me to the next thing... extended ROM. I sort of get the impression that if there is anything specific to my carrier that it is contained in the extended ROM? I've seen people discussing how to unlock the extended ROM, though I haven't figured out how to do it myself, mainly because I am not sure if I have to. If there is nothing for me to gain, I won't do it.

In a nutshell, I own a UTStarcom 6700, my carrier is TELUS Mobility, and I would like to upgrade to AKU 3.3. (I understand that AKU 3.5 is still buggy, like no USB sync support at the moment -- correct me if I am wrong.) I see a lot of posts throughout the forums, but nothing really all in one place. I would love a step-by-step detail of how to do it. In fact, if I could get a few people to help me get this going, I would offer my services to create a how-to with screenshots, etc.

If someone could help me with this, I would really appreciate it. If something comprehensive could be written up, could we sticky it?

So any word on Crossbow yet? I've heard a couple people might be working on it. I'm guessing it will include all of the benefits of AKU 3.3 and then some?

Thanks in advance!
[One (M8) Accessories] Ndaoud360:
Just found out HTC is going to release a charger that will charge any snapdragon 800 and above HTC device; 60% in 30 mins. I may actually get that depending on the price BUT then again I hardly ever need to charge my device more than once a day unless I didn't charge it overnight.

Also Motorola has a quick charger too. Not sure if its faster than the HTC one BUT it is compatible with HTC devices.
[One (M8) Accessories] PunishedSnake:
I wonder how much faster does it charge than the note 3 charger?
[One (M8) Accessories] Rouz.:
One thing to keep in mind though, charging the battery that fast can actually decrease the battery's life span. a healthy recharge would be a slow one. Yet i can see why some people would need a rapid charger.

This topic should probably go under the accessories.
[One (M8) Accessories] ivicask:
I agree 100%, its a simple fact in all battery's, faster charging means also less capacity from each charge and faster draining of battery and also shorter battery life in general..
[One (M8) Accessories] Chris_c81:
From what I understand, this is not just a case of throwing more voltage and current up it.

The QC2.0 chargers are different. They utilise technology within the charger and the phone, I'm assuming to distribute the voltage and current in a stabilised battery friendly way. You can use a 2a charger on any device and it'll charge a battery quicker but risk reducing battery life. These QC2.0 chargers only charge Qualcomm devices rapidly. So they have to be different to regular chargers.

I'm lead to believe they kick out 9-12v at 2.1a.
[One (M8) Accessories] Ndaoud360:
I'd assume HTC would work on trying to not weaken battery life span while charging at quick speeds.
[One (M8) Accessories] PcFish:
It doesn't matter what software/hardware configuration is in it, as long as it's the same lithium polymer being used it will still be susceptible to stresses like deep discharges, charge voltage, temperature and load currents.

Also, the 60% in 30 min refers to Qualcomm's benchmark tests with a 3300 mAh battery. The M8 has a 2600 mAh batt.

[One (M8) Accessories] daboscovellen:
Does anyone know if there is any substantive data on whether chargers utilizing quickcharge 2.0 do, in fact, reduce overall battery life? I could see this being useful in some scenarios, but I like the battery life on my M8 and do not want to do anything to jeopardize it.
[One (M8) Accessories] Chris_c81:
Not until end users have done extensive testing. Qualcomm and handset manufacturers and accessory manufacturers are hardly going to advertise this information.

I personally do not believe it will affect battery life drastically. As I said before, it's a technology utilising chips and software within the charger and handset. It's not like shoving a 2a or greater bog standard charger up it.
[One (M8) Accessories] Ndaoud360:
BUT then again phone companies like to make your phone die quicker so you can buy their latest device. I don't HTC would do that so I believe they would try to make the battery stay the same length of time.
[One (M8) Accessories] Chris_c81:
Of course, I'm assuming you have evidence of that statement!?
[One (M8) Accessories] Ndaoud360:
It's just been rumored throughout the years.
