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

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.
unplugged my phone at 8 read xda forum for 5 mins got to work right now 943 already at 89 percent. Does this seem normal? I been checking better battery stats but don't really understand it. I feel like something is trying to sync. i have fetch off for email and Facebook. anyway to diagnose this on saurom rc4 clean boot.

I think I know what the problem is: Your phone is trying to kill itself and save humanity from that terrible font
seems like a bit much but it could be normal.
Once your phone's charge reaches 100% it stops charging to prevent damage to the Lithium-ion battery. I am not sure however when it starts charging again.
Mine charge % dips even when I am using plugged in! Horrible consumption with screen on.

Are you using the Samsung OEM home charger? It shouldn't be dipping when using that one. Mine will charge AND increase while using it in the car with GPS running (huge battery drainer) and a driving DVR program (DailyRoads Voyager) and the screen on. All with a car charger and cheater plug that shorts Pin 2&3. That's the secret to getting rapid charge to work. The OEM home charger has those pins shorted internally. If you are trying to charge over USB on your computer then again you need that cheater plug and ensure the USB port can support more than 700 mA. If it's a USB 3.0 port then it should handle that current.
No problems for me on the stock or aftermarket chargers with the screen on.
I have the same problem with my brand new I717 GN. Battery level slowly drops when on charge, even if it's the OEM wall adapter. I've tried my Kindle USB cables as well with about the same results. I noticed the charge is a bit stronger from the wall source, but still can't keep up with even simple web browsing via WiFi. I've installed JuiceDefender as well, and it's helped reduce depletion a bit, but not really enough. This phone would never last me a full day of intermittent use without a power source.
I've read several of these threads and there doesn't really seem to be a solid solution to this other than some GN owners saying they have the problem and some don't...
Someone mentioned a crosswired 'Smart Adapter Compatible with Samsung Galaxy S' on Amazon (I'm too new and can't post the link)... I might try that but maybe I'll return for a new one if some people don't have this battery problem, unless it turns out to be a latest firmware problem..?

I read an article in a journal recently about how smartphones charge their batteries. The article claimed that once the charge has reached 100%, it will stop providing current to the device until it reaches 90%, after which it will then trickle charge to maintain it at about 90%. All the while the battery meter will still show 100% (at least in the case of iPhones), but after you unplug the phone the first 10% will go rather quickly as it approaches the real charge level.
True for our notes? No idea. But with how Lithium batteries work, I wouldn't be surprised.
I haven't gotten my Note to discharge while plugged in with the OEM AC charger. In the car however, running Waze will suck the life out of it even while charging. (My car charger puts out about 150mA less than the OEM AC charger). Oddly enough, running Navigon on battery alone has less discharge than running Waze while plugged in...Which sucks, because while Waze has crappy directions, it has saved me many hours by routing around traffic. But at least the phone still charges while using Navigon and streaming some Pandora.
I charge the tablet like 3hrs ago, around 5 and 6pm, and its still in 40% ang then suddenly it drops to 39% (still plugged in and charging).
Im just surfing the web and some facebook, most of the time surfing the web. And i keep on killing task (manual kill).
Is my battery already broken?

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?
FYI car charger is weak as well usually - 1, 1.5 amps

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..
Sent from my SGP311 using xda app-developers app
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.
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.

My portable power meter seems broken so I cannot give you actual current draw measured in series. All I can do is paste output from Battery Monitor Widget.
All tests done with the official USB cable bundled with the tablet and screen ON at minimum brightness. Screenshots from Battery Monitor Widget.
Code:
Battery only: -721 mA (-10.79%/h)
Official charger (1500mAh): +719 mA (+10.76%/h)
PC USB3 port: -48 mA ( -0.71%/h)
No-name Chinese AndroidPC Charger
Model LA-520 (2000mAh): +1060 mA (+15.86%/h)
Energy Sistem K128 Charger (2100mAh): +960 mA (+14.37%/h)

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.
Sorry to be a nuisance, but I have a Baseus wireless charger installed in my car and all was fine and it did fast charging until it downloaded the UI 3.1 update.
Now the phone comes up with a ! in a battery saying that fast charging is not supported with this charger, so am a bit confused what's happened or changed, I like the fast charging aspect of it as it can put a good dollop of power into the phone on the way to work and I can also put Bluetooth on to link it to my car.
If it can no longer do this then I will need to change the charger.
So if this is the case, could somebody please recommend a fast wireless in car charger that will work with my S20+ 5G.
Thank you.
Interesting. I can't imagine wireless fast charging can be very fast, I was surprised to see the term.
Even Samsung talks about it albeit with no specs.
Samsung is historically notorious for bending the truth one way or another... you need to really scrutinize them carefully.
I wonder how "fast" it is compared to conventional fast charging with the 25w brick?
Apparently you're not alone and to make matters even worse the issue means no wireless charging at all to many of the effected users.
Samsung phones are having problems with fast wireless charging
The issues may have started with a recent security update

Best work around probably is to use cable fast charging and go for frequent midrange (40-65%) quick charges that only take 10-15 minutes but give enough mAhs to last 2-3 hours of screen on time. Li batteries love to be used like this and it can greatly prolong their service life.
Temperature matters; the battery needs sufficient temperature to support the electrochemical reaction properly.
Never start a charge cycle if battery is at freezing.
Avoid doing so if the battery is below 60°F
Below 72°F Li plating damage during charging becomes an issue and if it happens will permanently damage the battery's capacity.
Best start temp range is 80-90°F.
Fast charging* will not engage if the battery temperature is too low or high (approximately 100°F or higher).
Will disengage if temp goes too high as well when charging; first fast charging then all charging once it gets to about 101°F or higher*.
Best charging temp range is 80-99°F
*these charge throttling/auto shutdown values will most likely apply to wireless charging as well.
Thanks for the quick reply.
It's just that I find it most odd that this has only started to occur after the latest update, prior to that no issues whatsoever.
All I know is that when I put my phone into the holder, the jaws close and it normally says Fast charging: xx% and a estimated time to full charge.
A typical fast charge takes about 15-18 minutes which takes it from ~90ish% to 100%, I like to have the phone up to full charge before I get to work as I never know when I might get another chance to charge my phone off the mains.
Another oddity is that I have a Spigen wireless desktop charger and that does a fast charge without any issues.

Updates... destroyer of worlds.
Hopefully they will correct it and push it out soon.
Try clearing the system cache.
Double check settings.
You can try a hard reboot (not reset).
The associated apks for it are probably in Android services but clearing its data would cause a lot of work resetting settings and may not help at all.
If you did a major firmware update ie OS upgrade a factory reset is a good plan, otherwise it's likely a waste of time.
I'm now even more confused, this evening I put the phone in the holster/charger and it instantly initiated fast charging and topped the phone up in 15 mins.
I've tried turning on WiFi hotspot, no change, WiFi on/off and it still charged at fast speed.
Turned Bluetooth on no change. So I don't know why it's doing what it's doing. Weird.
