Hello,
How can I tell if my HTC One Max is actually charging at 1.5 A? I've had the phone for about 4 days now, and it charges soooooo slowly. One night/morning it took almost 6 hours to fully charge from around 15%. This can't be right. There are times I've just sat in bed (Thanksgiving Day, for example) doing some light texting and light web browsing...all with the official 1.5 A charger connected, and at times the battery level DECREASED, even while connected to the charger. I have the brightness set to auto, and the screen timeout set to auto. This can't be right...
I downloaded a couple of apps from the play store that try to estimate the charging speed. Battery Indicator estimates that my phone is charging at a rate of about 14.3% per hour. It's also telling me my phone will take 47 minutes to get from 88% to 100%. WHAT!? Another app, just called "Battery" says my phone was charging at 684400 mA...then it changed to 219900 mA. (Of course, neither of these numbers make sense, either. That would be 684 amps or 219 amps...enough to blow something up.)
Again, I'm using the official charger that came with the HTC One Max saying it supports 5 V, 1.5A. I have other chargers lying around different rooms of the house...there's a chance that I'm not using the actual USB cable part that came in the box (it could be mixed up with an older one I had lying around), but would that affect charging speed?
Thanks for any help you can give me. I'm about to call HTC now.
you should really try it first with the OEM cable and charger, but it should not take 6 hours..if it does with the HTC cable/charger, take it back, its defective
assuming you are on stock, and not rooted/tweaked

1.5A charger charge 1500 mAh per hour so it should charge in about 2 hours and a half..
You have one problem of two ether your charge isn't good or your
battery.. if your phone run out of battery very fast then it's your battery else it'sthe charger

I had a friend of mine get a new HTC One and it tooks hours to charge.. it was the charger which was at fault. as said in the previous post. if it also discharges fast then the battery is at fault, if it only takes time for charging it is definitely the charger. i am guessing you have found the solution already lol

I think I figured out the solution: In any scenario, I was using the charging adapter that came in the box. The variable that changed was the USB cable...since I have several lying around in about every room of my house. It seems only that the USB cable that came in the box will charge the phone quickly...around 3 hours and 20 minutes from completely dead to 100%. Any other USB cables seem to charge at about half that speed. (And of course, charge time suffers when the screen is on and you're using the device.)
But I still find this really odd. I assumed all micro USB cables were created equal. Perhaps not. Am I missing something here?
That's odd. This phone has the quick charge component/feature from Qualcomm, but that should not make any difference based on the cable.
well may be the other cable were not plugged in properly and did not reach the charging pins in the correct place? Do you notice a difference in attaching and detaching the cables?
for whatever reason, factory cables ALWAYS work best with the device they came with..
sometimes aftermarket cables are ok, but you can never be sure...
If you can, use the cable and charger that your device came with; that will always be best.

I had the same issue. I was going to use my old S4 cable cause it is longer. It gave me a notification telling me to only use the charger that came with it. Was the cables fault. My guess is it is using an extra pin to tell the phone it is the correct cable sort of like how OTG cables work.

Mine has been taking forever lately, just took over 5 hrs to gov from 25 to 100%...WTF! My Hero with the 1500mah battery would charge from 10% to 100% in 1.75-2 hours this thing has a roughly 17% bigger battery but takes 3 times as long now to charge, it didn't at first when i got it but it is now no matter which of my 3 HTC wall chargers or my car charger I use. I don't know if the battery is going bad or what. Is there an app for displaying charging amps...I thought I read that there was but i can't find one?

I use Current widget (free in market).
Cool Thanks, wonder if that shows amps comming in to phone or just +amps over what the phone is useing...by the fluctuations I would say the latter. Works though.
That Current Widget worked great, when unplugged it shows draw and when plugged in it shows gain rate. Note for everybody, just because it sais its a High Speed 2.0 cable doesn't mean it meets the amp draw requirements. 2 of my skinny cable are only capable of transfering 500mah when the HTC cable and 1 of my thick ones transfer a full amp of juice. Good to know all my chargers work just have to get a thick-high quality 6ft cable now.
has anyone else noticed how quickly this phone charges? I just wanted to give some props to HTC.. I forgot to plug in the phone last night, and when I woke up this morning it was 0% dead. I plugged it in, and got ready for work, an hour later when I had to leave for work, it was at 96%!!
hell ya
Nice, haven't really paid much attention actually.
All I can say is that the ReZound is everything the my Thunderbolt should've been, including the battery charge and life.
Hmm.. I mainly just charge in my car & it seems like it takes forever(close to 3 hours). I spend most of my time driving otherwise i'd plug it into the wall and see. I guess it also doesn't help that the phone is also always being used while charging to.
However, battery life wise, it lasts 2 - 3 of constant use before it dies.

It will take longer to charge from a USB port and a car charger....won't take nearly as long when plugged into the wall. Just an fyi
Sent from my Inc HD
yeah, the motorola car charger or the htc one seem to be the best bet..you have to look at amps.
most ****ty car chargers are like 500ma, which will take like 3-4 hours to charge..you have to get the ones that match the AC charger, so around 1amp (1000ma) and you're set. the motorola is the closest i've seen, at like 950ma or so. charges it pretty well.
i have the motorola p513 rapid car charger & that's the one that seems to take forever. i've also got a 400watt power inverter & have tried just using the cable & wall plug that came with the phone and it doesn't seem to make much difference either. i've tried it in both the limo and my van... i know it's not a problem battery-wise with the van as there's 6 car batteries in it.
shazbot!...
I have the extended battery for mine, it seems to go from 10% to 100% in about four hours. I think for most phones it'd about three hours or so for a stock battery. So it looks like it does charge faster for me as well.

I ran my phone till it died today. I have had it on the charger for 1 1/2 hours, still barely 50%, I think you were on crack man. I was charging the phone with it off for the first hour too.

i used to have this problem until i found there was a difference between charging cables and chargers. I dont mean the amperage size, i mean, some chargers/cables put your phone into USB charging mode, which is much much slower than AC charging.
THere is an app on the market called 'current widget' that can tell your charge rate. I used it on an older phone that was compatible with the widget (rooted rommed and cust kernel) and found that the charger I was using wasnt "AC" charging my phone, even though it was an AC charger. I went through a couple of cable charger combinations until i found the ones that worked right.
I have a USB car charger too (the kind you just plug a USB cable into). Using the widget i found that the USB cable I was using in my car was not 'AC' Charging the phone, and as a result, if i used navigation or anything like that, the phone would deplete power faster than it was getting it. I changed cables and problem was solved.
You can download the widget and use it on the rezound, but it does not update correctly, nor does it seem to be as accurate as it should.
For example, if I am not charging the phone, it should say "0 mA, but it does not. I have noticed though that when I am getting a good charge, the charging rate does show an increased rate, and because I am failure with the app, ive used it to confirm the charging rates.
You can try to download the app and run it. Plug in your phone, and look at the 'mA'. While its not charging it will be ~100 or so. during charging it should be up in the 500-600 range. but the app does not update as fast as it should, so you have to let it sit a bit before the number will change (normally it changes in realtime) but after charging for 5 min or so , if you still see numbers <200 you are not charging at the optimal rate. Try a new charger / cable.
I have 6 chargers, lol. All of them are 850mA chargers.
Here's a screenshot from this morning, I went to bed with at at 5%, and looks like it was full charged within 2 hours time. Not bad!

You know current widget shows how much your phone is using right? It never says 0mA when your phone is charging because your phone is using current when it is in use. It never goes to zero at any time actually unless your phone is dead.

that is not the way it worked with the droid charge with a custom kernel. It showed your charging current. or more accurately, the amount of current that was going to the battery for charging. When the charger was unplugged, it showed 0mA.
Maybe we are talking about different apps
that is really fast. I wonder if that is why some of them are overheating and going into bootloops...

Hehe... That "Current Widget"... When I use my Belkin USB car charger dongle, it fluctuates between 100 - 300mA... When I use my Power Inverter, it's 400 - 900(depending if the engine I'd running or not.
The bizarre thing though, is when it's not even plugged in/charging, the widget still shows mA fluctuations and makes me wonder if the thing is even working or not.
Alright peeps, I just got this Belkin 2.1amp (2100mA) usb car dongle "rapid charger" from Walmart. The packaging says it's for tablets so I'll see how it holds up against the mighty Rezound.
I've had my new HTC Amaze 4G for 4 days now and absolutely love it, what a great phone! The battery life is great (I'm careful with all my settings) and I'm only finding issues with the charging TIME.
It's the second time I've charged it and after noticing how excessively long it took the first time, I clocked it this time and it took 4 hours and 45 minutes. I used a charger that I've used on many other devices with no issues (5 volts 1 amp).
The battery level increases 1% every 3 minutes, which adds up to 5 hours. I calculated this both with the screen on and by averaging out over a longer period of time with the screen off. I also tried with the phone completely off and the results were the same.
I made sure there were no processes hogging up processor time or excessive RAM usage.
When I go into to "Settings -> About Phone -> Battery" Battery status clearly states: Charging (AC).
I have also read somewhere that this can possibly be set this way by design (possibly to prevent the battery from heating or overcharging and saving its life in the long run).
I also realize that the phone is new, and the battery needs a few charges to be settled, but 5 hours to charge on the second charge just seems like too much.
On the HTC product support website, on the faq there is the following question/answer:
How long should it take to charge my battery?
"Your battery can take up to 4 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function."
Can anyone out there with an HTC Amaze 4G confirm how long their phone takes to fully charge from the AC charger?
I'm thinking/hoping this is a defective device/battery/setting...I don't like having to wait 5 hours to have my phone fully charged.
Thanks in advance,
Filipe
Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks
Come on....anyone? Please? This is driving me nuts!!
Yeah that sounds about right. Don't complain man. Your battery life is pretty good compared to other devices. My device takes 3 hours to fully charge and can last 24 hours with minor use. Just charge it when you go to bed and you won't notice the time it takes
My desire hd takes almost as much (Around 3 hours) and my Optimus 3d prolly takes even more (5?) to fully charge from a full discharge...
(With Stock HTC/LG Charger. The HTC's AC Adapter is 5V/1A [Shouldn't that charge a battery in under 1 1/2 hrs?]. Not too sure about the LG)
They take Much longer to charge on Computer/Laptop USB Ports. The Optimus 3d actually loses battery while charging (With screen on) with a USB port.
Also, 5% a night is pretty good. My desire hd goes down 3-5% per night (2g, no data enabled.) or 0-1% with Airplane Mode. (Rooted, Revolution 6.31)
And my optimus 3d pretty much runs out of battery in <100 mins with full brightness while Playing Games - It goes down more than 1% per minute depending on the game being played, especially if 3d Converter is used. This is pretty much the same for all GB/Froyo ROMs.
Just charge it when you go to bed and you won't notice the time it takes

I Agree. Both phones usually last around a day at least for me. You could always try a battery monitor such as GB Battery Stats or watchdog (The CPU One). CPU Intensive applications and Awake time during sleep are usually what cause bad battery life. Faster chargers such as 2A ones should also charge the battery faster, but they might reduce the overall battery life.
I would suggest buying a wall charger and cheap batteries from ebay. They last almost as long as stock batteries and cost only ~$2-4 each. [They apparently explode though. Never happened to me.]
-------------------------------
Both phones seem to charge from 0-90% much faster than 91-100% as well. I'm not sure why, since 100-90 wastes just as fast as 90-0. (Charging from 90%-100% battery practically takes a third of the full charging time)
many thanks
RESOLVED (Sort of...lol)
Thanks for your feedback guys!
I just finished charging it this morning, and it's FASTER NOW!
Took exactly 2 hours and 37 minutes (Battery Moniter is a great app!).
I think it actually may be due to the phone having some sort of smart charging system which "looks after" the battery. Since the phone is new, it might be wanting to start it off with some slowww charges and gradually speed them up.
But I still have to narrow it down some more since this time I'm actually using the supplied cable and charger (the ones I tried before were also 5V/1A).
The cable I was using (had it for a while now) had a pinch or two, it didn't look that bad, but I'm thinking it could also be the cable (could be shorting)!
I'm gonna do some testing on this cable now and report back my findings!
Thanks again!
RESOLVED!!!
Ok, so it actually turned out to be the cable. I really feel like a dumb ass...lol. Oh well, at least I figured it out!
So yeah, one good way to see if your cable / charger is good is to use Battery Monitor, and on the main screen where it says your device is charging (AC) and etc..it will also say the actual amperage (in mA) being fed to the battery...that number should be within the 500 to 750 range, if its lower, there is likely something wrong. (Mine was at 16...lol).
Thank you all for your help!!
Cheers!

My problem was the cable, and it was causing the phone to take five hours to CHARGE, not discharge.
These phones don't hold charge for too long, and the more activity you got going on, the more power it will consume. The screen hogs up the most power, so using the device constantly (especially with high intensity background light) will drain the battery very quick. First smart move would be to set the screen intensity to the lowest setting. Wi-fi and bluetooth, if you're not using them, shut them off. Open your task manager (or get a decent one from the market) and kill all the apps you got running in the background.
Games also require a lot of graphics/processing power, so naturally they will drain a lot of battery too.
Edit: There are some special cases where it could also be related to your network or even simply coverage zones exposed to the device. If it's stuck in a zone where it has weak 4g and 3g signals, it will keep bouncing back and forth causing more drain than normal on the battery as well.
If you've taken all these things into account, then you may have a defective device, then you will want to setup an RMA...or just take it back wherever you bought it and ask to exchange.
Hope this helps,
Cheers
My skyrocket takes about 3.5 hours to charge from 10% to full charge. If I plugged it in the car charger and run google map with the radio on the background, it would slowly drain the battery even though it was plugged in. My iphone 4 did not do this. It charges very fast and does not drain the battery even when I had several apps running in the background. I think the skyrocket consumes more power whether it is plugged in or not.

Hi, what you need is a charger with a higher amperage rating than 500mA (or 0.5A). Buy a charger that is rated for 5V/1Amp like this one and your problems should go away.
The phone is basically "burning" more energy than it is receiving from the USB charger, hence the discharge.
To know the amperage rating of your charger look on the label for numbers that look like "5V/500mA"...
Hope this helps,
Cheers
EDIT: The link I provided does include an iPhone cable, but I'm just referring to the charger itself, the cable would obviously have to be a micro-usb.

thread moved to...mexico?
Most illegal threads are trying to move from Mexico.
But, you need a charging source more powerful then the base 500ma, (or whatever that term of measurement is) computers are only supposed to supply 500ma to a USB port so AC adapters are typically better for charging. But feel free to follow the post above and check the rating on the charger.

Make sure to use the original charger and cable that was supplied to you by T-Mobile/HTC
I noticed the 12-pin cable is faster than the 5-pin.

Is this with the charger and cable it came with? I am not having this problem but different chargers and cables can cause issues

Yea I had mine at 10%, put it in to charge. Come back home 6-7 hrs later and it's only at 44%?!?

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...

I'd also believe this might help charging faster while not using the device. Could anyone try that, please? I'm interested in the results. (My XTZ hasn't arrived yet )

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...

WTF...
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 had my tablet plugged into my pc and while I was using it the battery actually went up a 1 or 2 percent. I got mine two days ago so maybe it's an early production issue?

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,
Hello,
when the tablet was in the charger with 1000 mAh and my GF was playing plant vs zombies 2, it was not enough and was dead in 2 hours. So I put there the official charger 1500 mAh but then still it was not enough and was dead again.
Right now I tried to turn off the Location, Wi-Fi and she is playing. But is this normal??? Jesus you should be able to play with all the functions turned on and in the charger, not???
Edit: so it was emptied again even with everything off...
Edit2: i will try the origin cable because I used a different one

Did it show the charging icon while she was playing the game? I'm curious if it might be plugged but not recognizing that it should be drawing power from the charger...
Because charging cables are differently wired, you MUST either use the original cable or a cable which is definitely known to have the same wiring as the original one.

Differently wired how? I didn't realize there were wiring differences, please elaborate if you can, feel free to get technical.
I tried plugging my Z2 Tablet into a USB cable from a powered hub (computer off though), which I've used to charge my phone and my Kindle, and I know it wouldn't have much power, but it wouldn't charge at all, no charging icon, nothing. I've had no trouble charging it with a dedicated charger though.
~Troop
So yes,
1. the charging icon is there
2. I even logged the history and during playing the plant vs zombies 2, the power is oscilating around +- the same level but still going down slowly as a trend
3. I tried today to get the power back to 25% and now I am charging it. I have the battery widget where it shows getting mA about 390 to 890 maximum. But even it is the original charger, original cable and the charger is 1500 mA it seems that the maximum level is 890???
Can someone else try Batter monitor widget what they get from it???
Edit:
It sucks. It announced even today DURING charging from the original charger and cable that the charging is not strong enough. Wtf?
Edit2:
Here they say it is charged under 3 hours. Not my case :-/ http://www.digitalversus.com/tablet/sony-xperia-z2-tablet-p19609/test.html
Ha, that is really funny. I am from the Czech Republic and called the Sony support. They forwarded me to Xperia support. At Xperia support the girl said that she cannot provide me exact information because official release date here is 8th of April so she doesnt have the manuals etc.
Then my type is 511E3 which she again was absolutely no aware what is the type because I should have 621 or maybe 521 but not 511.
So I can try the support line next week with the question how many mA should go to the tablet during charging.
But what she said was also that the charging time could be up to 6:20. But more than 6 hours? Maybe it was about the Z1 model? And also told me that playing games with the charger will still result in draining the battery.
I need some other guys here who can test it with playing some games and check the mA during charging...
I don't have a Z2, but just wanted to mention that cnet saw the same (no charge while playing) in their review: "[..] the tablet lost power even when it was plugged in to the mains" http://www.cnet.com/products/sony-xperia-z2-tablet/2/.
I never experienced any of this. There's probably a problem with your unit.

And have you tried to charge it during heavy playing of some game? Which game, how long?
Can you test how much mA are you getting from the charger inside the tablet (battery monitor widget can do this)
I tried it yesterday playing "The Cave" for about 1 hour. Tablet was charging using a four port no name charger and a different cable the that the one provided.
I did not really check for anything , I just noticed the tablet got mildly hot.
I did not measure the current while playing, but I did earlier this week-end though.
I tested 3 chargers plus the provided one. A Galaxy S III charger, An ASUS TF300 and the 4-port no-name I used yesterday.
If I recall correctly I got around 0.9A from the GS3 and original charger and around 1.2A from the TF300 and 4-port ones.
I do some more thorough testing and let you know. I use a device on the charger output to measure how much current is coming through.
How long do you guys charge the tablet? I started with about 19% and to full 100% it was like 7-8 hours. It was turned on without wifi (stamina mode). I will try to charge it while turned off but still it is strange...
I dont know. Battery life is ok but the charging sucks for me. Any ideas if it is just me?

Yawn... Please use the charger and the cable which come with the device (which I bet my grandma on you didn't)! Other chargers or cable have either too low current or wrong wiring (which disables fast charging) or both.
The charging time over USB is 4-5 hours, like the first generation Tablet Z.
Yawn, yawn, if you took a look then you would read from this topic that I use original cable and original charger.
If the battery is 6600 mA and charger 1500 mA then the minimum for charging is 4,3 hours approximately. And as I said my maximum charging is 890 mA. So either something is taking 600 mA during the charging or the charger is bad or the cable is bad or I dont know.
But if it is in the stamina mode and still the maximum charging is 890 mA then something is weird.
I am asking now for about 5 times. Could somebody test during charging how many mA is going into the tablet? (You can use Battery Monitor Widget from google play).
Neither Xperia support is able to give me clear answer because the Tablet was not officially released here (which is funny, I have it).
Thank you.

Dude, then simply go and exchange the charger if it is faulty. No need to make long XDA threads out of that.

Its not about charger. Or maybe it is. I want to know exactly how many mA are going to the tablet during charging. Nobody was able to give me the answer.It could be faulty charger, faulty cable, messy apps in the tablet (which I doubt) or whatever.
And Sony support, Xperia support is not able to give me clear answer to this. And also another guy in a review had similar problem. If we are in a Z2 Tablet topic then I supose that this is the right place to ask such questions... Not?
You can't just do 6600 divided by 1500. You are losing current all over the place when charging. It will probably be at least 50% wastage in heat, resistance in the wires etc etc. Also, the charger may say it does 1500, but that is peak when it's brand new under perfect conditions and the internal components will age and become less efficient over time too.
If you are using the tablet for a game, it will be running the processor at max power and drawing lots of current and all the heat it generates from the cpu and the battery during this time is wasted energy don't forget. If you want to battery to charge, you will need a charger that provides enough current to power the tablet and another 1000ma or so on top of that to charge your battery.
I bet Sony will state somewhere that you can only use it for low power activities like watching videos while on the dock if you want the battery to charge.

Thanks a lot!
So it just means that in general with the original charger you are able to get to 10-13% per hour. So in average usage 9 hours of charging, heh. I saw yesterday (have to check it at home) that I had also around 20% per hour.
But in general these figures are normal and the usage of a battery with a little bit more heavy tasks is not very good. And charging can take a LONG time. I tried to charge it while turned off and I think you can get there below 6 hours.

mm.after read all of reply above, it is quite weird that only get 800mah while using 1500mah support charging cable? Maybe can try better quality of cable and also the power source, it is very crucial to get that. I have try some trial and error with different cables and charging with my galaxy s3, i find that with good quality of cable, i managed to get 1000mah max , but if using with cheap cable or power bank, i only managed to get 400-800mah. even after a long time using the original s3 cable, it will reduce to only 600mah. So my advice is try charging with different cable and find the best cable to charge ur device, if it is 1500mah supported, so i think it should be support to 1500mah. Thank you.

No, it is not weird at all since the tests were done with the screen turned ON, draining half the power.
The first line, battery only, tells you how much the screen and semi idle state is draining, with brightness at minimum. Cranking brightness up to maximum increased an extra 2.5% per hour drain if I recall correctly.
Charging with screen off would be about 20% per hour, or 5 hours to fully recharge. More or less in line with what people is reporting.
Code:
Battery only: -721 mA (-10.79%/h)
Official charger (1500mAh): +719 mA (+10.76%/h)
So, 721+719= 1440 (+21%/h), pretty close to the rated 1500 for the charger.
