Is it possible that if i use another device charger like blackberry or whatever compatible may give me a better battery life ? I saw on x8 forums a guy claimed using an htc charger and posted a screenshot where it showed up to 6 days of usage !

The charger is just a simple 5 volt power supply.
The charging circuits are in fact integrated into the device/phone itself.
You woulnd't be able to affect the battery capacity in any way by using a different charger.
I'd say that claim about improved battery life due to changing the charger is very unlikely. I'd call it a fake.
Perhaps improve charging time, but not improving battery capacity.

Overcharging a lipo battery in a device such as the X10 (Lithium Polymer) would end up in either one of these scenarios:
Scenario 1: Phone and battery overheats, thermal protection kicks in and disables charging permanently.
Scenario 2: Phone and battery overheats, frying the internal charging circuits. Permanent damage.
Scenario 3: Phone and battery overheats, causing an explosion. Worst case: exploded battery catches fire.
Battery fires are tricky to put out and can cause major damage, not only to the device, but also to everything around it.
Don't worry tho.
As long as the charger, or whatever power supply you're using, gives 5 volt DC with correct polarisation, you'll be safe.
But as soon you fiddle around with different voltages, specially anything higher than 5 volts, it starts getting dangerous.
There is a common misunderstanding on how volts and currents works.
People tend to believe a charger with higher currents will do better. That is wrong.
It isn't the charger that "pushes" the current. It's the device that "draws" the current needed.
Example: If the device needs 700 miliamps, and the charger can give 5000 milliamps there will be 4300 milliamps left over.
In theory one could connect 7 devices to the same charger: 7x700=4900, and still have 100 milliamps left over.
What would happen if the device draws more than the charger can give? The device wouldn't charge at all, as the charger would "drop out" in one way or another by either shutting down, or lowering it's own voltage below "acceptable level"

Did you guys notice the battery take too long for full charge? Especially charging while in use. It seems doesnt charge at all
Could anyone help me out? I was charging and surfing web the XTZ at the same time, but the battery even went down by 2 to 3% in 3 hours even though the tablet was charging. Is it common or should I exchange it?
Thanks
Is this with the charger and cable it came with? I am not having this problem but different chargers and cables can cause issues

Yes. I used the original charger and cable. When I let the screen on while charging, it seems like its just preventing the battery run down, instead of adding more charge. I guess I got a defective battery. When the screen off, it just take too long for full charge, like almost 9-10 hrs. I test the cable and charger with another device it seem working fine. How long it take for you to do full charge when screen of btw?

I don't know exactly how long. But charging and using the device at the same time is no problem and adds charge at an ok rate. I would guess that a total charge would take around 4 hours but it is a guess.

Have you tried Stamina mode while charging? I believe it shuts down some background processing while the tablet is asleep. Might help speed up charging.

I did some research and this is what I came up with...
-- the USB charging seems to be hard-limited to a maximum of 500mAh intake. This is consistent with the original USB specifications, although no one really adheres to those anymore anyways. Charging with 500mAh is bound to take a long time and presumable even light usage (screen-on + sufing) will prevent charging at all and still drain the battery or keep it at the same charge level. I consider this a quite major design fault and wonder why Sony did this - if they had any strong reasons (overheating near USB port due to the thin build and no heatsink properties of the material?) or if it can and will be adressed later on by software (I am not sure if that is the case...)
-- this also means that using different chargers (if they work at all, the Tablet seems to be picky and did not make use of two generic ones that were tried, only a HTC wallcharger was accepted next to the original Sony one) that put out more than those 500mAh will either not work or they will deliver just the 500mAh the USB port accepts as a maximum
-- however the charging cradle contacts will readily charge the tablet with up to 1500mAh
If one were to assume the worst of Sony one could say they probably limited the USB charging to a minimum to push the sales of their original chargers. On the other hand one can argue that SLOW charging is actually better for the battery longevity, so Sony could defend that move with that reasoning...

There is a thing that while playing "heavy" games and charging from usb connected to pc it even dicharges. If connect it to stock charger (1.5A) it manages to charge but very very slow. There are chargers for 3.1A or even 5A which will charge your device very quickly.

Have you actually tried one of those with success? If so what is yout exact serial number for the XTZ ? As I laid out in my post a little bit above yours the XTZ seems to not take more than 500mAh via USB even from any charger...

i just did check the charger ... its 1500 mAh output. But it surely doesnt charge with that so clearly usb is limiting it Oo. So clearly dock is a must not only no flaping cover but also faster charge. Anyone with dock can confirm that ?

I guess this how they boost the sale of their dock and avoid overheating..limit the USB output. They also sell the micro USB and charger on sony website. Dont know if it could make any difference.

I noticed that if I set the brightness to the minimum, I would be able to charge while screen on. If I set to max or somewhere middle, i would not. did it happen to you? if not I think my battery got issue then.
I believe mine was on auto brightness for that moment. I did notice that in the last two days, full brightness drains the battery A LOT. Within 2 hrs of screen time I was down to 55% battery

Just got mine XTZ and so happy with it, but same thing it take so long for charge it even with the wallplug.
I just notice, i have the XZ and if i use the cable directly on the phone it take a long time for charge it too. But if u use the dock my phone charge in less than one hour ( or maybe a little bit more), So i can guess is a usb limitation on the sony product (or maybe a marketing trap)
Sorry for my English.
In my case, since i've the Galaxy S4 ATT version, i use that wall charger i've not tried the one that comes with the tablet but the S4 charger is a 2A while the Tablet Z is 1.5, with the S4 one + stamina mode + auto brightness + special mode(only 1 core running under clocked to 1036Mhz, conservative governor) my tablet charges ultra fast from 10% to 50% in 1 hour and half or even less, also my standby time is up to 8 days at full battery.
If you have your tablet rooted and you want to use my special mode, just download CPU Adjuster from Play Store, give it root permissions, then create a screen off profile, 1 core, max 1036Mhz and that's it.

why should it be like that? We have a 6Amp battery in there and if it WOULD charge all the time with 500mAh max we would have a charging time of 12 hours. But if the battery reaches 80% charge charging will be much slower. That means if your statement would be true, we would have charging time of over 14-15 hours.
I charged mine in 6-7 hours. 6000/6=1000 so it´s normal for our 1,5 Amp charger.
Okay, tested it. Shorty story is, there is no difference between charging via dock and charging directly via USB port.
Long story:
- variation tested: SGP312 (WLAN 32GB)
- Battery percentage at start: 58%
- Charging time: 70 minutes
- Charger used - the one which came with the Tablet. The dock does not have a charger in either case, you have to use the Tablet one (which I do) or a 3rd party charger for it.
The only difference between the tests is that once the USB cable went directly into the Tablet and once the USB cable went into the dock.
Battery percentage after 70 Minutes with USB cable: 80%
Battery percentage after 70 Minutes with Dock: 81%
So basically, it got from 60 to 80% about ~1150mA / hour independently of the charging method.
As a sidenote, bringing it from 80% back to 58% took 28 minutes of playing a 1080p mkv at full display brightness,

The app can only tell how much different the battery is, not how much juice is actually flowing into it. Meaning, the possibility exists that you phone is *using* juice while it's charging, lowering the amount of difference the app can see.

Thread fail. Voltage output, as verified with a Fluke 77 Type IV multimeter, is spot on 5 VDC. Current, which is governed by the phone, has been verified by many to a max of 1900 mA.
I can see just from the screenshots that the app is detailing misinformation. Were your phone actually charging at the rate indicated, it would take approximately 26 days for it to fully charge, assuming no use, from the 76% in the screenshots.
Oftentimes you get what you pay for. Such is the case with Amazon's Free App of the Day sometimes.

I had an iPhone 5 that charged ridiculously fast compared to older phones.
When I'm charging my new S 4, how do I get the faster charge rate?
I'm currently using the Moto 2 USB wall outlet charger that came with my razr maxx hd. And it seems like it takes way longer then my five and I chalked it up to having twice the battery.
Is there a faster way to charge?

The new charger is amazingly fast, if thats a word. I was going to use my.old charger from the s3 at work but its so slow it barely keeps up with use and can't keep up if I'm running my wifi or playing games. Now I just need to find a car charger thats as fast as the new charger.

Keep in mind there's more to it then just the wall charger's output ability. There's something in the S4 that recognizes the original sammy charger and turns up the charge rate yet will only allow a trickle charge on other non-sammy 2.1A wall chargers.
It appears that dome people are aware of this and have managed to modify the non-sammy chargers to enable the faster charge. Then there's some semantic confusion between "quick charge" and "fast charge" features that may be enabled in roms or kernels.
All I know is I wish there were more info on this stuff.
A little knowledge of how Li-ion batteries charge is an important thing. Li-ion batteries have special charging requirements.
The part you plug into the wall... thats not a charger... its a power supply. It provides a 5v DC output at up to 2 amps.
The charger is built into the phone, and it determines how to use that available power to charge and power the device.
Li-ion batteries charge in a two stage cycle that is called "constant current/constant voltage". It is also important to know that a battery's voltage drops as it is discharged. (this voltage drop is how the battery meter gets its information, as it is predictable when tested under constant loads... the variable load of a phone is why the meter seems to be inaccurate at times)
During the first phase, "constant current", the battery is fed a constant current at the same voltage as the battery is currently outputting. As the battery takes in energy, the voltage rises but the current is kept constant.
The second phase, "constant voltage" starts when the battery reaches its highest voltage. (or more accurately, its highest safe voltage, which is around 90% capacity) During this second phase, the battery is fed a constant voltage, (the max voltage) and the current varies. The battery will draw as much current as it is able, and this rate slows naturally as the battery reaches full capacity. When the current drops lower than a certain set amount, the charger stops the charging process and the battery is said to be fully charged. This second phase is slow compared to the first phase, and that is why it can seem like the last 10% of charge takes longer than any prior 10%.
Some phones use the power supply to both power the device and charge the battery, the battery is electrically isolated during charging... but most charge the battery without isolation. Either way, the power from the power supply is being used to both charge and power the device, and this limits the charging speed.
This also limits the maximum capacity the battery can be charged to while in the device, because the voltage/current measuring is less precise. Unfortunately for these phones, the charging is controlled by software, and not simple hardware circuits that are isolated from the battery power. In fact, even when charging the phone with the power off... the phone is still actually powered up but in a low power background mode. This mode is actually a special screen off recovery mode. CWM recovery has had several instances of bugs, where the phone could not charge if the battery died to the point of powering of the device. Because the phone could never power into the special mode to start charging, due to this special mode being missing from, or bugged in CWM.
Also... these batteries have on average a 2-3 year lifespan, and also limited number of recharge cycles. The 2-3 year life is the same even if the battery is unused. As the battery ages, it looses capacity.
Charging at slower rates is better for battery lifespan than higher rates. Now the batteries in the S4 and especially the Note 2 are larger, and 2A is still considered a fairly slow rate, but of course 1A is even better. If you tend to charge only at night while sleeping, it may be better to use a 1A charger.
Awesome explaination !!! That makes complete sense and explains things. The point made in a prior post, about the phone recognizing the new charger, thus charging faster makes sense as well. The new charger must "turn on " the quicker charging on the S3 as well, because it charges my old S3 as fast as my S4. I didn't try the charger on the older firmware but it definetly works with the latest update.

What do you use to charge?
Big screens need a lot of juice and XTZ is bigger than most.
A PC USB port supplies usually 0.5A, while Sony's charger is 2A... Both can be insufficient to charge the device while in use, but the wall charger might manage it if you only use WiFi + display...but not really sure.
For comparision some tablets even refuse to charge at all from weak sources, like phone charger or PC - the iPad.
Unfortunate Sony doesn't tell if the juice is enough.
I can see you used it most of the time you charged it and the WiFi - is it Facebook the app that's using it so much?

The Sony charger I have is 1.5 A (UK version). There were lot of comments about slow charging etc and about how a 2A charger charges the XTZ quicker. I installed an app from the play store called "Battery Monitor Widget". I used it to record just the current drawn. I used the Sony Charger and also another 2A charger at various times, the current drawn does not show any higher than 1.1 Amps with either one even while it is in use. So I don't know if the 2A charger really makes a difference. I only charged from 70% to 100% and back. I will check lower values a bit later and post results. However what I did notice was if I use a long cable (to test - longer than 1.5m), then the charging current drops. Use a short cable, or Sony's own cable, the current goes back up suggesting the XTZ port really monitor the charge port.. The Charging current almost always started off with 500 mA +, which is probably why the PC USB port could not charge it; I say probably because the PC I have is quite old and has only USB 2. Anyways, maybe installing the app and keep it running in the background may give you some indications of the charging current drawn..It actually creates a timestamped log file which you can analyse later as well..
In the tool there are options for calibrating the battery etc, but I have not used it, and I do not know how it works and if it works in XTZ. I just monitored the charging current.
I did a test by draining the battery to 26%. Then when I start charging, the charging current is shown as ~850 mA. This is with Wifi on, and screen brightness set to Auto.Then when I increase the screen brightness to max, guess what, the charging current is either 0 or shown as discharging, which means the battery won't charge. Brightness set to Auto or low, causes the charging current to go upto 850 and the % charge also increases. Given that the charger is capable of 1.5A and I have seen on occasion 1.1 A being recorded, I am not sure why it charges at constant ~850mA. Possibly due to differences in voltages. This is with Sony Charger (1.5A)
I tried it with a 2A charger, and when the screen brightness is set to max, the charging still takes place although at a very low 100mA. And normal charging shows a current of ~950mA. Which is probably why some people noticed faster charging with a 2A charger as opposed to the Sony supplied one.
In short, if you want to get the tablet to charge properly using Sony Charger, try keeping the screen brightness to low or screen off.
I must qualify the above by saying I am not an expert in chargers.. Just putting down something I noticed..

Well, i charge it with the one that came with the XTZ so its the normal charger.
Usually i charge it overnight before i sleep and turned off it just happened that i charged it early and screen is the one eating so much for about 55% next is android os and others are below 10%.
Actually im thinking before it happened i installed some games but as i said others are below 10% so im fine with it
Also im thinking about the current, because when i got my XTZ im in my aunts home and whether i charge it turned off or on it charges fast and when i got back on my apartment then charging becomes slow..

For all charge you use simply the Sony cable (quite short idd) and their own cable?
I haven't monitored with the app, but I belive the 2a charger I used charges faster. Mind you I,ve never used the XTZ while charging, I spoke from expirience with other tablets.
PS: If you use the cradle you might want to check my other topic - I had issues XTZ refusing to charge when low batt and 2A charger...

Charged mine for a while this morning in the Sony dock with power on, wifi on, screen off. Like others, I use an iPad charger (2.1A).
The battery went from 11% to 55% in about 2 hours, so about 22% per hour - though I think it slows down as the % gets higher.
Just as title says... is it safe as if it were plugged into an outlet?
I don't see why not.
I have done it a few times already. Just stays slightly warmer I think. I use a pma wireless charger if that makes a difference or not.
I got the official Samsung one best buy gave out. Think that's Qi

This is why I wish manufacturers would start posting maximum surface temp specs for their chargers.
With that said, I'm guessing that Samsung's is reasonably built and won't get too hot. It also helps that part of the device hands "off" of the charger (that's also part of why I prefer circular chargers to rectangular ones).
Just make sure you keep the charger itself on a cool surface, and if you're one of those people who likes it to be 85 degrees in your house, you might not want to leave it on overnight. You could honestly probably rig the thing to vibrate itself off of the charger after a certain time lol.
I have been charging my S5 wirelessly every night for the past 6 months. I just used a low amperage charger so that it does not charge too quickly/ heat up too much. I am going to do the same with my S6 Edge.

You mean you bought a charger with low amps or you use a low amp plug that's not necessarily for the charger?

I use an original Samsung wireless mat and am using a low amp wall plug with it.
I got the duracel power mat that was from amazon.com and I leave it on overnight. The power mat seems to not stay constantly charging it. When I wake up my battery is full and it's not excessively overheating. It's a PMA charger, not a Qi one.

Well I've got the original Samsung Qi charger with the fast charge plug for the phone and I plan on charging mine overnight tonight. If the phone blows up I'll report back! I doubt it'll be an issue as the charger will surely only draw as much current from the power supply as it needs, and in-turn charge the phone at the recommended rate. I've been topping it up throughout the day on the wireless pad while I set up the phone and while it got warm I wouldn't say it got overly hot.
Edit - Charges quite fast on the wireless pad! Only been on there about two hours and it's charged from 24% to 97%! Certainly quicker than my old Nexus 4 charged. Was warm when I picked it up but will keep it on the pad overnight anyway to keep it topped up and I'll report back if it explodes!

Mine made it through the night without exploding lol... in fact, mine was cool to the touch and was not even charging when I picked it up... I think the samsung charger must shut off once the phone reaches 100%
Edit: the technology must be built into the s6 edge because I just put it back on once it dropped to 99% and it charged to 100 then the light on the charger turned green, the phone lit up and said fully charged and then it was no longer charging. Definitely seems safe to leave on overnight.

My findings too! Like yourself, phone was cool to touch, and light on charger (and phone) had turned green. :good:
Which is good Wireless charge with a 2amp out
Safe Wireless Charging
I am a traveler who takes a lot of photographs with my iPhone and Samsung S6 and so far Wireless Charging has been working well for me. I have proved that in many occasions while currently here in Southeast Asia (Cambodia as of this writing). Before leaving the US I made sure I was equipped so I shopped around and found a variety of safe Wireless Charging devices. IN my travels I would find myself tired and exhausted but need to charge so tendency is I fall asleep and wake up the next day and the device has cooled down after reaching 100% (during my sleep presumably). Look for devices like these.
I hope this helps!
