ram and battery life

funny the excuse they give (i-mate, htc, whoever) for not including more ram...

similar excuse was used by nokia people, but this time for not including a faster processor (that was for nokia communicator n9500) ...

i guess any excuse is good to legitimise cutting corners and increasing profits, they think customers are fool, well i ain't... :lol:
[Xperia Z1 General] appelflap:
I have to say that the Snapdragon 800 Quick Charge 2.0 feature is working pretty darn well. I measured 60% charge in 1 hour (just got the device yesterday so it's a fresh configuration)

Love that feature. Definitely makes worrying about battery life a little less stressful.

[Xperia Z1 General] ssj_jaypee:
doesn't work for me, takes a few hours to charge. do I need a special wall charger?
[Xperia Z1 General] appelflap:
I used the standard charger. Btw the 60% charge in one hour is just based on one observation. It was my first charge. I started charging the device from 1%. An hour later it had already 60%

Don't know yet if it will slow down when it reaches the full 100%.

Anyway, it's just a first observation. Need some more observations to determine the average charging time. (Wonder if there's an app for that)

Can someone link the 2.0 quick charge cable.
[Xperia Z1 General] Sean473:
You need a full charging adapter and cable probably... Can't find anything on it!
[Xperia Z1 General] ptoner:
It's susposed to be USB 3 I think and have an output of 1.5-2A in order to quick charge... though any info is severely

lacking.
[Xperia Z1 General] bramgg:
You need the charger that is supplied with the phone to be able to use the QuickCharge 2.0 feature. I don't know if QuickCharge is also restricted to the USB cable that is supplied with the charger.

Other generic chargers (like chargers you got with your phone 2 years ago) will charge your phone but not with QuickCharge. So it will take longer, just like any other phone without the feature.

Please correct me if I'm wrong, but I thought it was required to use the specific QuickCharge charger to use this feature, and yeah, it does charge a whole lot quicker this way! :D

EDIT: These new chargers are backwards compatible so you can also charge phones without the QuickCharge chipset with the special QuickCharge charger but they will charge normally and will take a long time to reach 100%, just like the ol' days.
[Xperia Z1 General] fer2503:
i use the charger of xperia z because the written specifics are the same of z1 charger. wrong?
[Xperia Z1 General] The PyroPath:
Cable is funky. Tried two other cables because the standard one is so dang short and both resulted in charging slow as a snail...:(
[Xperia Z1 General] appelflap:
Oops, maybe I was wrong and doesn't the current charger support Quick Charge 2.0. My Z1 came with the Sony EP800 charger. It seems that they already used this charger even before Quick Charge 1.0 was released.

Anyway it seems that Quick Charge 2.0 adapters may come soon. The components are already on the market http://www.dataweek.co.za/46872n

Quote: "Tests confirm that smartphones with high-capacity batteries can be fully charged in as little as one hour using Quick Charge 2.0"

Oh yeah! :)

Anyway, my Z1 still charges pretty fast. But no problem when I can get a full 100% charge in an hour...!. Would be even better when they put this technology in a portable charger. Maybe the newly released http://www.sonymobile.com/global-en/products/accessories/portable-power-supply-cp-f1lam/ ?
[Xperia Z1 General] Giant_Gonzalez:
Mine charges seriously slowly with the bundled charger/cable, not sure if I've just got a duff one. Charging it throught usb plugged into the computer charges it at a normal speed. Planning on picking up the dock when it finally gets released, hopefully thatll give a good speed.
[Xperia Z1 General] benziii:
I had an hour between ordering the phone and the dock from Sony store.

I got the dispatch note about the phone and hoped that it would not be long until I got the dock aswell.

Phone dropped off at work a couple of hours ago. To my amazement, there was a dock in the box!!

So I'm guessing I will be getting an extra dock in a few days then lol.

This is obviously not a problem, as I will take the second one and rip it out of its shell and use that as the charger I bring around with me.
[Xperia Z1 General] jos_031:
Dock yet to launch..october 1st week is tentative schedule...
[Xperia Z1 General] benziii:

No problem anyway, as I already got one, so atleast i don't have to play the "flap" game:p
[Xperia Z1 General] sveintore:
I'm not sure that the charger that comes with the Z1 is Quickcharge 2.0.. The link in the original post says it won't be available before 2014?
[Xperia Z1 General] gtrab:
There IS a differrence when using generic USB cables.

I've got consistent measures in some tests:

Sony Xperia Z1 original cable: 50-60% charge in 1 hour

Sony Xperia Z original cable: 50-60% charge in 1 hour

Sony Cybershot TX30 original cable: 50-60% charge in 1 hour

Sony car adapter original cable: 50-60% charge in 1 hour

Generic USB cable brand "A": 25-33% charge in 1 hour

Generic USB cable brand "B": 25-33% charge in 1 hour

All tests done with the Xperia Z and Xperia Z1 charger (they are the same).

The only difference is both generic USB cables are longer (6 ft vs 3 and 4 ft)

I dunno why but the USB cable has a lot to do.

[Xperia Z1 General] jos_031:
I used a usb extender and the charging speed went terribly low.. I think it is due to loses in the cable...
[Xperia Z1 General] kekni:
I'm having trouble charging over usb, is it because usb doesn't provide enough current or do I have a faulty handset?

Edit: When I say charging over usb, I mean from a usb port on a laptop.
[Xperia Z1 General] jonmorris:
I remember when tablets with large batteries couldn't be charged from some chargers, or via a USB port, so I wonder it this is the problem?

Also, do we know for a fact that the Z1 supports Quick Charge 2.0? I thought this had been delayed, and probably just supported the older version - as seen introduced on the Xperia S.
[Xperia Z1 General] gallardo5:
When connected to USB in laptop, it charges with 3.7 volts, and AC charger sends 5 volts, thats why it charges slowly when connected to laptop
[Xperia Z1 General] kekni:
My apologies, I should have explained that the phone is not indicating that it is charging at all.
[Xperia Z1 General] gtrab:

[Xperia Z1 General] sveintore:
The dock is acting a bit strange. It won't charge from USB on my 30" Lenovo display.. Even if the port is "always on" and actually delivers up to 2amps of power.

But when connecting a standard microusb cable it charges as normal..
[Xperia Z1 General] Exidouce:
I can confirm that the only way I have found to get a "quick" charge is with the supplied adapter and cable. I tried other combos suing various cables and power adapters and it would barely charge 40% over night.

With the supplied sony cable and charger it's pretty quick.
[Xperia Z1 General] sveintore:
iPad charger + dock charges well. A long micro USB power only cable did not work.
[Xperia Z1 General] Jiyeon90:
Im using the standard dock charger that came with the phone and the charging time is pretty good, normally it takes about 1h20min to go from 20% to 100%
[Xperia Z1 General] sveintore:
Tried a standard 12V->USB adapter today with three cables, none work. A bit confused..
[Xperia Z1 General] lshian:
Ok. I tried on my powerbank, it work perfectly. With phone on I still can get 1500+mah

of charging through powerbank through Power Bank 2.1A port.

I did a modification on my power bank which the middle two short together. It work

on my docking charger too.

Nokia's new tablet, which also uses a Snapdragon 800, has a charge speed of 80% in 1 hour! http://www.scribd.com/mobile/doc/177983016/embed?access_key=key-1n4sdjrl63a21nuwebhe&width=1280

Wonder if it is just a matter of using an appropriate adapter... http://www.dataweek.co.za/46872n

If so, can't wait to get my hands on the Nokia tablet adapter :P

But then again, if the adapter technology is finally ready for production, why wouldn't Sony or other manufacturers with a snapdragon 800 processor launch an appropriate adapter. Good for marketing also.
[Xperia Z1 General] Mighty_X:
That takes me like 3 hours :-\
[Xperia Z1 General] 301stSpartan:
Let's clarify a few things here as there seems to be a bit of confusion and/or misinformation going around. First, the charger that comes with the Z1 (or at least that came with mine, EP880) is NOT Quick Charge 2.0. As far as everything I've heard, QC 2.0 charges won't be available until 2014. However, our phone WILL support it as all Snapdragon 800 chips will support QC 2.0.

Now when you charge your phone (or anything else) the speed by which it charges will be limited by the output coming from the source. This is measured in Amps (A or mA). Various sources provide different power levels which lead to different speeds. Here are a few:

- USB up to 2.0: 500 mA (.5 A)

- USB 3.0: 900 mA (.9 A)

- Charger that came with my Z1: 1.5 A

- Quick Charge 1.0 technology: .7 A to 2.5 A

- Quick Charge 2.0 technology: 4 A and up

As you can see, our (and I mean the one that came in my box) Z1 charger doesn't even fully reach the potential of QC 1.0. QC 2.0 will have much greater output in terms of Amps.

And as you can see, when plugging into a computer the type of USB makes a big difference. Furthermore, many computers have specific USB ports designed for charging that will provide more power and charge while the computer is off (look for a lightning bolt by the port on many computers).

Additionally, different USB cables are made differently. USB 3.0 capable wires have a certain standard that other USB cables don't have to meet. Cheap wires are made cheaply. The quality (and to an extent the length) drives how much power is lost in transmission.

Finally, if you look at our battery it is rated for 3000 mAh (milliamp hours). This means 3.0 A output for a period of 1 hour (or 1 A output for 3 hours or .1 A output for 30 hours). So under ideal conditions with no loses (doesn't happen in real life, but is theoretical) you could see that the 1.5 A Z1 charger should in theory charge the battery fully in 2 hours (1.5 A * 2 hours = 3 Ah = 3000 mAh). Don't rely on this exactly, but take the concept and see how the outputs above (in Amps) would affect the charging time (in hours).

Hope this helps. Cheers!
[Xperia Z1 General] lshian:
That true. Actually in theory if you are using 3000mah lithium ion battery you can charge it at 3000mah in one hour. But actually not, as when the battery reach 90% of the capacity it have to slow charge to prevent overheat.

Lithium polymer have a higher charging capacity. Charging at too high amp will create a lot of heat. This made the cpu and gpu inside a small compact phone running while charging. No cooling and without any ventilation.
[Xperia Z1 General] Rekoil:
I felt the same but was too lazy to write it up, good summary, thanks!
[Xperia Z1 General] 301stSpartan:
Exactly. That's why I said use the concept (A*h=mAh) to understand the affect of more of less amps coming from the charger, but not to rely on the times exactly. I'm also really curious to get my hands on a QC 2.0 charger and see how fast it really charges and how much heat it generates. Who knows when they'll be available here in India though :what:
[Xperia Z1 General] funky0308:
Great post [MENTION=4596319]301stSpartan[/MENTION]

That's the great example how to explain something.

I know I get it now ;)
[Xperia Z1 General] *R2D2*:
I wouldn´t be so sure of that. Unfortunately I couldn´t find any detailed information, but most likely the S800-SOC isn´t the only requirement in the device to support Quick Charge 2.0. It´s quite save to assume that the power-path on the PCB to the battery must be designed accordingly as well. And we don´t know if that´s the case with the Z1.

And even if there are all hardware-requirements for Quick Charge 2.0 are fulfilled, the Firmware could still use a lower input-current.

The current alone doesn´t tell the full story, you have to look at the voltage as well.

The battery has a nominal voltage of 3,7V. With 3Ah this means 11,1Wh of energy.

USB and the charger has a voltage of 5V. With a current of 1,5A it can deliver 7,5W on its output.

So the charger can deliver as much energy as the battery can store in about 1,48h.

But of course that´s not the whole story.

To fully charge a Li-Ion battery you always need about 2,5-3h, regardless of the charger you use.

You can charge the first about 80% of a Li-Ion-Battery very fast, below 1h wouldn´t be a problem. But as the cell reaches about 80%, the cell-voltage already is about 4,3V. If you continue to charge at this fast rate cell-voltage would rise dramatically and finally destroy the cell.

To avoid this you have to reduce charging-current drastically. And the strange thing with Li-Ion-cells is, the faster you charge the first 80%, the slower you have to go for the last 20%. So in the end you will always end at about 2,5-3h for a charge from 0-100%.

So in the end quick-charge 2.0 won´t improve pure charging with a device like the Z1 a lot. The charger delivered with the Z1 is already powerful enough to charge the first 80% in about 1hour and 10min.

A more powerful charger, and a device that can actually use this power, will only be a real improvement if you want to charge your device, while actually using it. Like for example when you use the phone in car for navigation.
[Xperia Z1 General] Rekoil:
I can't be sure of this of course, but I wouldn't imagine Qualcomm would approve an S800 design which didn't conform to the QC2.0 standard.
[Xperia Z1 General] 301stSpartan:
Yeah, I've been thinking that since I posted that Sony might not support QC2 with the other internals even though the chip can. We'll just wait and see.

As to the voltage, as I said earlier, I was just explaining the general concept to clear up confusion (people were running around comparing charging times on different chargers and all confused about whether it's quick charge or not). Wasn't trying to get into too much detail, but rather explain simply that different chargers have different outputs. You're right of course, but I wasn't trying to write a textbook :sly:
[Xperia Z1 General] *R2D2*:
I don´t think Qualcomm has to approve anything.

They sell their SoCs and other ICs to everyone who is willing to pay the price. But they can not force anyone to use every feature their ICs have.

I definitely wouldn´t expect any feature to be present, which wasn´t advertised the time you buy something.
[Xperia Z1 General] Rekoil:
Yeah but there would have been a team of Qualcomm engineers helping Sony design the board that the Z1 runs on. (Or, like, at least one engineer)
[Xperia Z1 General] jonmorris:
I think most of us will have got a new phone (Z2 or whatever) by the time the power supplies arrive. It also means Sony (and others) will have something to shout about when selling newer models, even if the Z1 might be capable.

I'm sure that's why Sony left out 4K video recording too.
[Xperia Z1 General] yaabaa1986:
Dear xz1 users,

I use to drive rc cars, the battery's i used I could charge with a wall 230v wall charger. The full potential of the battery wasn't met. Later i used a special charger so i could put in how muxh a i wanted to use, this way i could get all of the potential of the battery pack.

Can we do the same with our phones?
[Xperia Z1 General] *R2D2*:
It could be possible in theory, but it is very unlikely that this is possible.

A hint, that there is more capacity in your battery than indicated would be if you had very fast charging times. Chargers that claim to charge a Li-Ion-battery in 1 hour or even less simply won´t charge it fully, but only to about 80% and then indicate that the battery is fully charged.

But it is very unlikely to happen on a phone. Phone-batteries usually aren´t designed to live very long, and a constant problem for smartphones is too low battery-life, so it is very unlikely that any smartphone will waste some power the battery can actually store.

Besides, the charger is in your phone and not the thing you plug in your wall. This is just the power-supply, and changing the power-supply wouldn´t change the maximum charge at all.
[Xperia Z1 General] ahomad:
Qualcomm said that all phones that come with SD800 WILL support quick charge 2.0, but you are right about the firmware though. Sony might not release this and keep it as new feature for next year phones.
[Xperia Z1 General] mastakrishna:
Sorry to refresh an old thread, but as the Z2 phone and tablet are already out and AFAIK having QC 2.0 chargers could somebody confirm if it takes a bit shorter to charge the Z1 with a Z2 charger?

I guess it's not only me being curious about it :)
[Xperia Z1 General] c312eal:
Fast charging isn't good for health of li-ion batteries. I rather to have a slower charge to prolong my battery health.
[Xperia Z1 General] jonmorris:
I think the point of the fast charging here is that it is controlled and intelligent enough to reduce damage.
[Xperia Z1 General] c312eal:
To fast charge a li-ion you just feed it a lot of amps. Fast charging regardless how you set it up is still straining on the battery. It is best to slow charge a li-ion to prolong its health.
[Xperia Z1 General] doomtrain85:
1 an half hour from 10% to 100% consider fast charging ?

@OP:

how the hell did you do that.

My phone does not use quick charge, C6903

Where di you get that from?

Motorola Turbo charger is 12V 1.2A in Quick Charge 2.0 mode, 4A seems crazy.
[Xperia Z1 General] 301stSpartan:
From Qualcomm's QuickCharge spec sheet. 2.0 is capable to do up to 4A, but it also depends on the device (the battery in the phone many not be able to handle that much so the manufacturer will cap the charging rate). My new OnePlus One comes with a 2.0A charger and charges damn fast. 4A would be insane, but I've never seen a 4A charger, and not sure if any devices actually support this max.

Edit: just saw another source that says 3A, though I'm fairly certain the official spec sheet I saw was 4A. Either way, don't think it matters much
[Xperia Z1 General] richmaster1o2:
I tried with a 2A charger, and Phone charges 25% faster, the Sony charger charges the Phone with 1,5A...
[Xperia Z1 General] bimmerboii:
Correct me if im wrong but the Z1 doesnt support quick charge 2.0. Some Z2 and Z3 do support it though.

I dont get it.. where are you guys getting that your z1 support quick charge 2.0?
[Xperia Z1 General] user822:
You are absolutely right it does not support it.

It does not even support v1.

The topic title complete nonsense.
[Xperia Z1 General] jonmorris:
Surely it does support V1? I think the first Sony device that supported faster charging (which I assume was V1 at the very least) was the Xperia S.
[Xperia Z1 General] user822:
I measured 5V and 2h from 0% to 100%. Does not look like it supports v1 :(
[Nexus S Q&A, Help & Troubleshooting] syed239:
Hey guys,

My brother's Sprint Nexus S 4G is stuck in a bootloop. It's stuck on the colorful Nexus X screen. It hasn't been rooted at all and is COMPLETELY stock. Is that even possible on a stock device? He said that a little drop of water fell on the screen but I don't think that this is what's causing this problem. I really don't know how to operate the recovery of this phone because I'm always running CWM on my phones. And he has had this phone for about 18 months. Any help would be great. Thanks
[Nexus 7 (2013) General] KedarWolf:
Hey,

You can hide the navbar by adding "qemu.hw.mainkeys=1" without the quotations to the end of the build.prop in the /system folder. You need to be rooted of course.This will remove the home return bar on the bottom so you'll be using your full screen space with none used by your navbar. Only do this is you are using a third party app like Button Savior or GMD GestureControl to navigate between screens though so you don't open something and get stuck there. Just make sure you backup your build.prop in case you make an error somehow, messing with it the wrong way can cause a bootloop but it can be fixed by flashing your rom or the stock android again though I had zero issues when I did this.

Hope this helps some, saw this post http://xdaforums.com/showthread.php?t=1985592 tried it and it works for the Nexus 7 2013 WiFi.

Peace. :cool:

P.S. In my Nova Launcher Prime I can hide my Status Bar and Dock as well, nothing but full screen if I want. Not sure how to do that on a custom rom or on stock though.
