Today I took my DNA for a spin using google maps. And to power the beast I used a 2000mA momax charger. To my surprise halfway through the trip I noticed my battery level had halved. I remember seeing the charging icon on the battery so thought ok its charging it.
But when we arrived after a 45 mintue drive i lost over 50% battery It seemed it wasn't charging after all. The phone was extremely hot
Did it get too hot possibly while driving and stop the battery from charging as a thermal safe guard from overheating? I'm on the stock kernel. Anyone had this issues like this? And does anyone know the MA rating of the official DNA charger? I'm in New Zealand so i cant just pick up the official charger or anything like that.
If i cant use the GPS without the phone charging it will make it unuseable on long trips
Edit: Problem found, phones gets too hot on the dash and running GPS it will throttle and not allow the battery to charge. Thumbs down to HTC making a phone with GPS that can't be used for more than 20 minutes or your phone overheats.

the rating on the HTC charger is 1000mah.. one thing i have noticed that some higher MAH chargers will actually cause the phone to charge in "USB" mode.. when you plug that charger in check the battery settings screen and at the top it should say charging AC or USB.. if it says USB then that is likely your problem since USB charging mode is much slower than AC charging mode.
Awesome tip. Never knew that, thanks!
Wow thanks very useful info indeed. I think i might be over doing it and making it overheat. I will try a 1000mAh charger in a few days and see if that solves the issues!
So the problem doesn't lie with the actual mA output of the charger, but with the way the charger is physically pinned out. On "fast" chargers, that is, chargers that can deliver more than 500mA of current, the center two data pins, D+ and D- are shorted. This short tells the phone that it's plugged into a dummy charger and allows it to draw more current (I believe the DNA can draw a max of 1 amp when in AC or fast charge mode). In a computer USB port, these two pins obviously aren't shorted as they are the data pins. Without the short being present, the phone assumes it is plugged into a computer where USB 2.0 specifications allow for a maximum of 500mA of current draw, so the phone software limits the charging rate to 500mA. The flaw in many aftermarket chargers, even the super high power ones, is they omit shorting the center two pins, resulting in the phone only allowing 500mA of current draw. This is a problem with both car chargers and some home chargers, especially the multi-port chargers designed for iPads and smartphones. Apple uses a different pinout for their high speed charging that isn't as simple as shorting the two data pins, so many Apple branded or "compatible" chargers don't put Android devices into fast charge mode.
For a car charger, my personal favorite is this Motorola one from Amazon. It provides up to 950mA of current, is genuine Motorola OEM so it's built well, and best of all is only $5 with free shipping if you have Amazon Prime. The only drawback is the LED is kinda bright and annoying, but I keep it in the outlet inside the center console so I never see it. http://www.amazon.com/Motorola-Vehicle-Adapter-micro-USB-Charger/dp/B000S5Q9CA/ref=sr_1_1?s=wireless&ie=UTF8&qid=1356666975&sr=1-1&keywords=spn5400
Yeah I use that charger too. Works well. I recently bought a dual USB output one that claims it puts out 1amp..but my phone shows USB mode. Is it only putting out 500 then?

Your phone is only drawing 500... I have a qmadix 2 amp micro usb with an extra usb port and it puts out plenty of power to charge 2 phones while using gps and listening to music.

Thanks for the info, still not luck for me. I brought a brand name 1 amp charger and used it again. It charges well to begin with. But after about 10 minutes the notification LED in the phone will start to flash .... Then it seems my DNA is not charging at all. Status bar tells me in the beginning it was not on USB charge. After the 10 minutes no charging detected at all. Its as if the droid disables charging.
I will check the cable too again and see if that was the issue. It might be the charger and or cable. But the first charger charged my Note II without any issues and fast. It never lost battery %
And again my DNA was scorching hot. Which seems to me more of an a throttling thermal issue. Its reaches xx temp and charging is disabled. Does the flashing led mean something? It was a sunny day and its summer here in New Zealand so the droid just got too hot maybe? Being black on the car dash in the sun cant help it.
I love this phone, and have my note II up for sale but if i cant fix this issue it seems GPS and Nav is a no go for me. Which is not good. I travel a lot.
Update,
I did some further testing and the news is bad I used my standard HTC DNA charger, and tried to repeat the conditions. Got my phone hot and low and behold. On the charger it will stop charging once the phone gets too hot. It will flash a green light, then orange, and repeat.
in other words if you want to use this phone in summer on your dash as a GPS you might want to think about running the A/C on it at all times
Can other please test this? Maybe i just have a faulty CPU, but i think its a built in thermal safetly feature once the CPU gets too hot it will not allow you to charge it. So in other words if you want to use this phone in summer with sunlight on your dash as a Nav/GPS think again ;(

This sounds right to me. My last 2 devices had the exact same issue when heating up. I do believe that fast charging really heats up the battery, so once it hits a threshold, it stops drawing power in order to cool off. Don't want a battery exploding in your phone.
The GPS radio can sometimes draw a bit of power, though it is much less on newer phones.
I digress, I really do think that in most cases, heat is the issue.
Its a very sad state of affairs, I cant use this phone as satnav / GPS without loosing a lot of battery life. Seems its only good for winter GPS when used on the dash in the sun of summer it will just over heat and not charge. Very poor if you ask me.

Try testing your phone at 'room temperature' (75 F, 30C), if your phone overheats using the GPS in this case, then you should return the phone because it is not normal.
If it is overheating on a hot dash board, ALL of my phones have done that. You can try blasting the wind shield vents to counteract the heat.
The DNA is normally great, but either your expectations are a tad unrealistic or your phone needs to be swapped.
A solution would be to mount it in a way that isn't in direct sunlight, like using one of those vent-mounted adapters. Then if it got hot, you could put the air on and it would cool it down.
Another option would be to either turn the brightness down, or to completely turn off the display, unless of course you have no idea where you are, and need more than just the audible directions.
But really, it sounds to me like your specific phone is just prone to overheating, and needs to go back. I haven't had any temperature-related functional issues at all.
Sure, it's gotten warm. But it's never failed me as a result of being too hot.

Well its summer here and its not taking the suns heat and being black doesn't help. I will see if I can move its position or place it over the A/c vent of the windscreen.
Wait till summer in the U.S and you will see more threads like these i think. I only comment its poor because no other phone of mine has done this in the past. Maybe mine is faulty.
Used mine for over three hours (one-way) using GPS/Maps full blown with no trouble or heat at all. I was also texting, surfing, playing games and talking on the phone at various times and had to plug in after awhile using the usual car charger. I don't like to get below 50% if I don't have to. Anyway, no trouble on the way there and no trouble on the way back.
HTC has always had the best gps radios I've ever used. My wife's GS3 still can't get as good, fast, and pinpoint lock as my DNA (or my Rezound for that matter).
As always, YMMV.
No offense man, but who the hell leaves their phone in the sun and expects it not to overheat? haven't you ever left your phone in the car in the summer and come back to a red triangle or a high temperature sign?
The key to keeping your electronics alive is to keep them cool. Your phone is just like your computer...you try to keep the temperatures as low as possible at all times.
I have a generic cigarette lighter adapter I got off ebay. I used my the google gps on my phone to a store in CT for the wife and then a trip to Boston, well over 3 hours worth of continued GPS use. When I unplugged the phone when we parked in the garage I had a full battery and the phone didn't appear to be any warmer than playing a regular game.

That's how every phone works. If you are using it in a hot environment and in direct sunlight it will try to cool itself down by stopping charging.

Sorry bud, you cannot expect to leave your phone on the dash in direct sun, while using GPS AND charging and not have less than optimum results. You are KILLING the efficiency of your battery by allowing it to overheat continuously. Keep it cool man!
People will find anything to complain about...
Bought this tablet yesterday after finding it for a €50 discount and reading some reviews. The reviews warned that the charger is a but underpowered, and they weren't kidding, after 15 minutes of being plugged it I've only seen it go up 3-4%. Worse yet, if I try to actively use the device (just some browsing, nothing intensive), the charger can't keep up at all and the battery charge starts dropping again, slowly.
I'm quite happy with this tablet, it's got a nice feature set, good performance, decent price; I don't want to return it. But not being able to use the device when the charge gets low is a bit of a deal breaker. So I'm left wondering.. is there a way to charge it quicker? Would a 3rd party charger with higher amp output work? Or doesn't it work that way?
be sure being charging with original charger and usb cable
I was having same issue during the first month with this device, i was charging it with another usb cable (much longer) else than the OEM one, My device took 10 to 12 hours to do a full charge, very annoying thing. After some thinking and asking other ppl about this issue, tried to charge xtz with the charger and usb cable included in the Box and voila, not only the charging time has reduced to no more than 3 hours, right now i can use the Tablet without no intensive power requierements (wifi browsing with minimun screen intensity) and can see how the charging state increase during use... Hope this can help u.
Thanks for the reply! Sadly I'm currently already using the standard USB cable and charger that came with it, but maybe my cable is just fault or something. As far as charging rate goes, 3 hours sounds like what I'm getting, so maybe my expectations are a bit high in that regard. On the other hand it seems like I should be able to at least use the device when it's plugged into the charger without running out of battery charge (even if much slower). Almost seems like it's just being drained abnormally fast, but according to the battery usage thing, ~90% is used by my display which I guess is normal
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.
Hello guys,
I am quite sceptical about gaming and charging simultaneously. I've got 2 cases here:
1) You played for a long time, so your phone needs some juice. Put in charger, keep playing while charging or better to let it charge in peace without any load and continue playing after the battery is full?
EDIT: I found the sollution. Asus claims that battery shall not get too warm when charging and beeing under heavy use due to that they move fast charging stuff from phone into the charging adapter. So this question shall be answered by myself. But still some users advice to let it charge without heavy use.
2) Your battery is full. You want to play games. Keep charger in while playing or rather put it out? I mean that if you let charger in, theoretically the battery should not drain any power, so all power suply provides the plugged charger so the battery is not beeing wore, is it?
THX for all opinions/replies.
I have been playing hard with the phone and had used both cases.
Case 1, you can play and charge at the same time. That is why you have a side port to be able to play in landscape.
Case 2, if the battery is full, keeping the charger connected or not should be irrelevant for operation. Now what happens to the battery, is a completely different matter. Depends on the construction and the actual procedures that Asus has put on the phone to keep the phone running.
On both cases it's not good for battery health
In contrast to laptops which use the direct cable power supply instead of the battery when plugged in, android phones use the battery at all times, so if you connect the charger while also using your phone, the phone will use the battery and an the same time the charger is charging the battery
In other words, you are killing the battery with your own hands because being charged and decharged at the same time is really bad for Li-Ion batteries.
That's why they say first charge your phone up and then use it, and repeat, that is of course if you care about using the device in long term, otherwise, just do whatever you want and you're good for at least a year...
Hello, My phone problem is, whenever i charged my phone to any certain percentage like 80%, 90%, 100%, and unplugged the charger and using the phone, first 5-10 minutes its consume 5-6% battery and first 1 hour of using its consume 10-12%.
This problem happening to all roms including stock rom
So it's not your 'roms'.
Tell me about your fone, how old, and what type of battery?
Does the fone heat up at all when it's draining?
Is there an extra slight BULGE at the back of fone?
I know some charger's, like the iphone chargers, can and do lose their amperage, it's how they sell more charger's, by providing the volts but not the required amps, or in this case, milliamps.
Let me know, and I'll try to help quick as

I know some charger's, like the iphone chargers, can and do lose their amperage, it's how they sell more charger's, by providing the volts but not the required amps, or in this case, milliamps.
Let me know, and I'll try to help quick as

My phone is 11 months old, and the battery type is Li-ion battery
no heat up while charging and discharging
cant sure is the phone slight BULGE at the back of fone?
By bulge, I mean, does it feel slightly fatter? Bigger? Swollen? can you take battery out, if so, is it neat and tidy, as in, lay battery on a flat surface, it should be flush with where you place it. If it's flat, turn it over, is it still flat?
Have you had any recent updates?

no its not slightly fatter and my phone has glass back panel.....yeah got new updates,but the problem is on every roms
but some custom kernel like etherious and agni kernel...the battery draining normally
So if your battery was getting fat, it would be time to replace it, but due to glass back, you cant tell.
Do you standard charge, or turbo charge?
Back in the 80's, I learnt a fantastic trick, read:
Batteries develop 'memory'. They remember how long they were charged for, in that they kind of copy the previous charge, and dont go further than where the previous charge was halted. Meaning if I'm in a hurry, and pull out fone at 60% charge, next time I plug it in, it MAY see the 60% previously disconnected, as full charge.
For instance, I buy a new battery, when I get it, I dont know how long it sat on the shelf for, as it's charge slowly dissapaited through non-use (yes this happens) while sitting on shelf. So when I get the battery, the first thing I do, is place an electrolytic capacitor (valued around double the voltage of the battery) and place negative of capacitor to negative and positive to positive on battery, the idea being to drain it completely. Once I get no power from battery, I then charge it for 24 hours.
This erases the 'memory' the battery develop's, making it like new from factory. The above is the 80's version of recycling a car battery. But you cant drain the battery, being sealed in your f'n, so try the following:
Grab a usb adapter, say a 4 port (mines a 7 port), and plug your powered on f'n into it, whilst filling the other ports with any other usb devices, the more power they need, the quicker you drain your fone., being the objective.
Do not plug the usb port itself into ANYTHING, and do NOT apply power to the hub.
Leave until nothing lights up plugged into the hub (have a thingy with lights plugged in to see the power drain).
Look for a 3.5mA usb charger, the type used for tablets, the amazon fire tablets charger is ideal for this. Once you have completely drained battery and know nothing else works cause your fone cant supply the other devices any power, plug your f'n into the 3.5 mA (milli-amp) charger, and charge for 48 hours.
This is the electronics engineering method of renewing a battery.
My scource is an old '80's magazine, co-incidently, I'm in same edition called CB magazine, the first ever printed version of how to make a battery like new. I hope this works, cause I dont know the actual fone, but if you do this, you'll have the added advantage of knowing you just 'made' a new battery, and learnt not to buy sealed fones where you cant release the battery to swap it.
As I say, if it's a hardware problem, you'll know after this.
Edit: I know apple mess with the charging cycle to make people buy new iphones, which they do in updates. Your problem MAY actually be this.
Good luck!

So in short You tell me to do that is, i have to connect a usb hub to my phone and discharging all the battery. then i have to charge my phone at least 48 hours/2 days?
Yup. If you take your time, and it's not hardware or update related, you'll be glad you did. At the very least, you make your battery brand new for sure.
Whilst googling, I found some saying some optimisation service wont stop, but hey, it's now down to you to help yourself

don't take me wrong......so the methods u told, really improved li-ion batteries..
and also i dont have any 3.5 ma charger....can i charge my phone on pc usb port
and when charging 48 hours, do i have to turn on the phone or charging with switched off

Yeah it works with EVERY battery made by man, unless it really is DEAD, like no acid to react to the li-ion, shame we cant add water like the car batteries of that time to prolong the battery life lol, back then was poor days, lots of handy finds were found...
I would not recommend the pc/laptop method, because I'm pretty sure those usb ports only provide 50 ma (a quarter of 2.0 mA, note the small ma compared with the 2.0 mA)
Power to pc/laptop end user style is 2.0mA devided by amount of ports.
Any single charger rated 2.5mA or above is what you want, so I use 3.5 mA.
Check old big phone chargers, look at the plug, go for more power than your actual fone charger, which I must ask, is rated at how many mA? I predict 2000ma (2.0mA)
The time (2 days) is to FORCE more power into the previous 'rememberd' memory, literally blowing it's mind lol. After this, you use your standard charger, this is only to fix BATTERY, so then we know if it's hardware or software, cause you did the work and patted yourself on the back lol
Edit: keep fone off while charging, just use another old one or borrow one till the charge is complete. By cheating you only cheat yourself lol. By doing, you WIN.

my phone charger is 18watt fast charger....than how many ma it has....and how many watts in 3.5ma charger??
Glad you asked. Your charger is a 2.3 AMP or 2.300mA like I said, try a larger charger
Look at charger till you get what I'm saying re: ma, mA or Amps (A)
2.0 AMP is 2000mA
To make it easy for you. 2.0 ma (how it's sometimes written) is = to 2000mA or 2.0 AMPS, but do NOT make the mistake of using 2000 AMPS lol, I'll hear you from here...
Electronics is defo not software and I forget sometimes i'm dealing in milliamps and amps, etc rather than megawatss from my radios lol
So you will look for a plug that MAY show EITHER 2000mA or or 2.0 AMPS. The old way to write milliamps were once similar, so ma was made mA to show amps. Keep my age in mind lol
