Hi, I wonder when you record video using tf300 in a quiet environment, could you guys hear high pitch sound? Mine has..
Sent from my ST25a using xda app-developers app
I confirm this, the high pitched sound can easily be heard. Shot some 1080p videos in a room and it's really annoying to watch them on a TV because then the sound is even more noticeable. Running stock rom, latest firmware.

Yah, really sad, this is definitely a hardware issue on the tf300.
Here's something I noticed:
If you have the transformer plugged in (charging) and record video, the high pitched noise is completely gone. But if you don't have it plugged in while recording, the sound is always there.
That interesting...

I'm wondering if there's anyone here that has the transformer tf300 that DOESN'T have the high pitched noise from their video recordings. If not, then I'm planning on returning mine

Checked on other forums, part seems like a lot of people are having this problem. One guy even replace his and with the new tf, still have the sound... Looks like this is a hardware issue.... But maybe there are something to donwith charging... When my tab on dock or plugged in there is almost no high pitch sound.

just had an idea. Get one of those mini portable battery packs (that you can stick a usb power cable into) and plug your transformer into the battery pack whenever you want to record video without the high pitch noise. Yes, it's a pretty inconvenient solution, but at least you'll be able to record good video with no high pitched audio until (hopefully) Asus rolls out a fix. Can anyone verify if this solution works?
My first TF300 didn't have the high pitched noise. Swapped it for another reason, and the next unit had it (both from the same store, in early june). Finally after months could not stand the noise anymore and sent it in for repairs. Device came back with the same problem, and as an added bonus, very loose upper right corner. Sent it back again. Should receive tablet in the morning (expecting same if not worse condition. Will keep sending until they fix the damned thing.
It's a hardware issues, and there will probably not be a "quick" fix unless they add some software audio filter for that specific frequency, and I doubt they will.

Well I can't be really sure it's a hardware issue because when it's plugged in (charger or charging on dock), the sound disappeared. Maybe they could increase voltage or something....

Who knows
Got my tablet back today. They seem to have swapped out the entire main board. The noise is still there, but slightly less noticeable. Don't know if it makes sense to keep sending the tablet back for this. In general the device is in much better condition than before... no creaking or loose corners, or anything. Except for the fact that the new main board seems to be prone to freezing and random reboots. Oh joy... I have to run some torture test and make sure if this is the case, and if it is... RMA again.
So, I guess in hindsight: don't fix it if it's not completely falling apart
I have one of those little AA battery usb chargers. I will test it and post results tomorrow.

The funny (not so funny really) thing is that to get around the first problem (high pitch), we're encountering another problem with the TF300. There's another thread here that talks about how the normal usb plugs aren't providing enough "juice" to the Transformer to properly charge it. Supposedly, you can take the ASUS cable but swap out the charger base that goes into the wall socket with another charger base and it will charge VERY slowly, but the ASUS provided charger is the only one that provides enough proper charge for now.
So- Tamaskan, your Sony battery might still be providing enough charge to cancel out that high pitched noise (even though it doesn't indicate that the tablet is charging). Have you tried testing the video with your Sony battery plugged into the tablet? Because it might still be enough.
And- To do a proper test, we need to get a battery pack that has enough "power" (I don't know if it's watts or amps, you guys would know this better than I ) to charge the TF300. The AA battery pack from CookieMonster sounds interesting.

If you're too lazy to check the threads (TLDR?), they also mention you'll need a Female to Female USB 3.0 coupler. This is the part they linked to:
Female to female coupler
I haven't had the time to verify that their models require the same specs that we require for our TF300's, but they mentioned something like 12V 2A is what they needed for their Transformers (reminder: these threads were not for the TF300, but other Transformer models). We just need to verify that it's the same requirements for us.
Pardon me if some of this is gibberish. It's almost 3am over here so I'm not bothering to proof this post. Just wanted to give you guys something to chew on.
Also- I just want the cheapest smallest battery pack possible. That way I can attach it to my tablet case and only plug it in to stop the friggin high-pitch noise if I want to record video. If you guys find a killer deal, please let me (us) know!

And no difference with the Sony portable charger.... Still has high pitch sound. I think the asus charger gives more voltage compared to normal chargers and usb ports which has 5v. This may explain why it charges really fast even with a much powerful battery, charges slightly faster compared to my xperia u lol.

I use TomTom on my Touch HD with a car charger.
The first charger I used was fine but since I lost it I cannot find a charger that works properly... At first I thought I was just using faulty charger's but as I have now tried 3 different ones I am beggining to wonder if the problem is with my HD!
The funny thing is that on both the main screen and in TomTom it is showing the status as 'charging'... even the light on the top of the phone is lit to show it is charging but the battery level is still going down all the time!
The only thing I can think of is that maybe the chargers I am using now are not as powerful as the first one I used? Or are all car chargers standard?
Either that or my HD is broken!
Can anyone please help me find a solution?
Ps. The phone still charges fine through both a wall plug socket and a USB connected to a PC.
The car charger I use I bought for my old Tytn 2 (original HTC one), works great for the HD and Diamond, even when the battery was at about 20% left on the HD, TomTom 7 running, screen brightness max, the battery was almost fully charged within an 1hr.
Think it's rated at 1amp, you might want to check the power rating on yours, anything under 1amp and it's really going struggle to charge while using it.
Unfortunately its not printed on any of my chargers what amp they are... I actually thought they were all the same amp but if some are more powerful than others this could be my problem.
What does concern me however is that even when the HD is switched off it is still not charging (even though the light at the top of the phone shows it should be!)
There are plenty of tools around (HTC's battery.exe, acbpowermonitor, battlog, powerguard, etc...) that can show you charge/discharge current. If your car charger gives you less than the unit is consuming, battery will not be able to charge.

I had this problem and found it was because I was charging through the usb socket on the stereo which always worked on Polaris but not with Blackstone. If I charge from the cig lighter socket it works good.

I bought a cheap and cheerful universal usb charger from tesco's for a couple quid. Works great and no problems with power whilst running TomTom
Hi, first post here and rather than start a similar thread so soon, i thought it best to post here.
Is it possible for car chargers to over-charge the device? I bought a cheap and cheerful car charger off ebay but was a bit concerned some of them are listed as having overcharge protection and this one wasn't. Wouldn't normally be bothered but its a £550 handset!
Cheers!
yesterday my keyboard suddenly stopped working. Whenever I dock the tf its as if nothing happens. Except when the dock is plugged in to the charger..then I see its battery icon...red...with a question mark. When I do logcat I see something like battery state unknown.
Anyone got any theories. Ibsadly lost the serial for the KB and I don't think I can rma. It.
Sidenote....as I type this I become more and more painfully aware of how I hate soft keyboards.

Grr...is there any way anyone would let me borrow their devices serial number. Asus wouldn't even start the email process without a serial.
Sent from my Transformer TF101 using Tapatalk
First of all, I'm the guy who soldered in a 500 gb hard drive into my docking station and some other people's docks. I know the hardware inside out. If you don't have any other option, consider sending your dock to me and I'll try to repair it. You pay for shipping. I guess I'll do this as a favor so I won't charge anything.
Again, explore your options and send me a PM.
Added by edit.
The serial is attached to your dock. How did you lose this?
I dunno if they changed the way they are attached to the serials on newer versions but on mine it was a flimsy sticker...which got rubbed off the device I guess.
Anyhoo...right before i went to sleep I actually had an idea of sending you a pm about letting me have your serial...as I'm a bit desparate (enough to ask a stranger for a favor) and I know how your mod (albeit quite awesome) renders your dock irreversibly un-rma-able. Then I log into the forum and here you are =)
Anyway...I might just take you up on your generous offer but I have a feeling that my docks battteries are the problem. Do you know if the dock works if the batteries are dead?
In the log cat....I see something like: unable to detect battery health €#£'#&'###'.
The gibberish part isn't verbatim...but there was a bunch of giberrish symbols after the message.
My symptoms are basically the tfiner doesn't respond at all to the dock....except when the dock is plugged to the charger...then the docks battery icon shows up in a red error state.

Even if the battery is dead, your dock should still work. My guess is one of the connection wires is the problem. Can't know for sure until I do some tests.
My serial number wouldn't work for the following reason. I sold my old one with the 500 gb hdd and got a new one recently. Upgraded it to 750 gb . So, my serial # is now B80. Yours, I'm assuming, is older than this.

Call me stupid but I did not actually know that. That's incredible. I have always found it weird (i use the dual battery app widget) that is shows my transformer at 100% and my battery dock dying. It's never really gotten to 0% yet. Does that mean when the battery dies the USB connections still work as well? So really the extra cost in the keyboard dock is the battery life. God I love this device.

Yup. I've disconnected the battery many times and the usb still works.
The note is a disaster for me when it comes to charging.
If your battery is low and you start charging it but using it at the same time, it doesn't get worse, but it doesn't get better either i.e. actually charge the thing, it just holds its own.
I have got to say I am not impressed with this!
I am not facing such problems. Charging takes pretty long yes but not as bad as you said. A larger battery will of course need a longer time to charge. But I wonder sometimes too if it's the battery problem or the charger output problem and if there's a way to speed up the process.

I think it is more to do with the actual charger, seems like a trickle charge or something.
Yes if charging and using at the same time you would not expect it to charge as quick, but mine doesnt really charge at all, just stays the same.
My acer iconia will charge like lightning even when i am using it, smaller battery or not it still charges!
This was one of the things i was looking forward to with the note, but this slow charge seems to make it more or less the same as what I am used to.
I have the usb plug which comes with the kindle, might it do a better job?
If anyone manages to find a proprietary charger which can produce better charging I will like to know too
That is common the charging is very slow and if you are playing HD games then the charging is almost in negative. May be its because of the voltage of the charger inputs and it is to low. Samsung must have done it for a reason may be its because of the proprietry port or the battery itself we do not know but we need to live it
Agreed, charging this thing takes a long time. Keep in mind that the battery is 7000 mAh and the charger is most likely a 2 amp charger, pegging the charge time at around 4 hours with no other losses. So if you're using it, it should take even longer.

No such issue here. I charge to full capacity while using all the time.
I get what he's saying. Because it draws so much power when you're using it; having it charging at the same time doesn't move the needle much. For example, if you're watching a movie while it's charging you'll probably be at the same point battery wise when the movies over. People complain about this all the time when their using their devices as a GPS. In some cases not only doesn't it charge but it actually continues to drain so you're worse off from where you started. We're using 21st century toys powered by 20th century battery technology.

This is a better way of saying what I mean, thank you.
I also have to say one thing I do not like doing is turning the screen brightness down. After all we all get these things as they look so good, so I am not going to make it look worse when I am using it, what would be the point in that? Its a bit like saying yeah my battery life is 14 days but actually it is on standby for that time lol...
Anyway, I still believe it should be better and the primary cause is the weak charger for what ever reason sammy decided to make it that way, but its not a good thing.
It seems like I remember someone recommending a charger that was more powerful so the note would charge faster. Can anyone confirm this?
What a fail thread. If you know ANYTHING about charging, you would know why this happens and why this is NORMAL.
But why even search or educate oneself, let's post a thread on XDA and whine a bit.
It could be worse. It takes six hours to charge a N10.
I dont face this problem i charge mine when surfing the wep
On a slightly related side note, doesn't it suck that the brightness just turns down completely when the battery is low?
The zslower charge rate protects the batteries life ,reduces the possibilty of heat and battery damage trickling insures a full charge
if you don't want your screen to dim don't use the power saving setting.

For all those facing the slight unresponsive screen please change the source of power, I had mine connected to UPS power supply as soon as I changed and connected it direclty the problem was gone.
Even if you read the user manual of Samsung Note its says thats one of the reasons
How Manhattan hours per day do you use the note? With a 10hrs battery life I find an overnight charge is sufficient

Wow! many friends?
Anyway moving on.. so i just got my note 10.1 about a week ago, loving it but saw that while plugged in it was not charging at all while i was using the tablet and never quite getting to 100% overnight. By not charging while using, i mean to say that it was actually discharging. Yes of course i am using the stock charger and cable.. and even stock note.
so just tried something silly. Unplugged and plugged the usb from the block repeatedly about 5 times. Now its not only recognizing and charging, but charging relatively quickly even while using. To test, i unplugged for about 20 min and plugged back in. Same great results.
Just thought i would share instead of hoarding my new found knowledge like others..
Quick update: it charged about 10% in 20 min.. Nice
I don't charge mine - I paid cash for it
After careful thought, I decided to return my shield tablet (so I won't be doing any dev work for it.) The tablet just isn't right for me. It has some issues, but so does every tablet/phone/etc. I'm not posting this to start bashing nvidia, etc... I just felt obligated to let people know that I've changed my mind and so won't be doing dev work for the device.
Take care

1. Anger at NVidia for what I feel was purposely misleading consumers about the lollipop release on the 18th (US/LTE). I know they turned a blind eye to the leaked update, but they should have disclosed the potential delay when they made the announcement.
2. While the battery life was acceptable, the charging wasn't (for me.). Even with a high amperage charger, the silly tablet would lose charge even playing simple games like "dots" or "threes."
3. I wasn't satisfied with nvidias resolution (or lack of) for the cracked edges issue. Too many customers were (and still are) experiencing the problem even after nvidia claimed it was fixed.
4. My wife asked me to stop spending money on geek toys, and I really wanted a nexus 6

Were you using the stock cable and stock charger? Some cables do not support high charge rates and even some high amperage chargers are wired for apple devices and most android devices cannot charge higher that .5amps with them.

The stock charger was worse than a computer USB port. I only use higher end USB cables, and I have various charging bricks from several different phones and other devices. The simple fact is that the charging circuit just wouldn't pull enough amperage. (None from apple, BTW). I even have 3.6 amp USB charging ports hardwired into my electrical outlets in various rooms of my house.

>The stock charger was worse than a computer USB port.
That is not right, and sounds like the power brick had a problem. Pc usb should only be providing .5 amps way less than the brick. My brick charges vastly faster than a pc usb port.
> I only use higher end USB cables
High end is only part of it, you need ones that are specifically built with thicker gauge cable.
>None from apple, BTW
It does not have to be from apple as most usb charger manufactures still follow apples charging standard. They do not do the standard for dedicated charging devices (short data pins) that most android device follow. Actually, every dedicated charger i have bought i have had to solder the data pins together for full charging.
Okay. You are assuming that I don't know my way around USB charging. The opposite is true. As well, it really makes no difference in terms of the nvidia tablet. It's gone.

It may not matter to you but the Clarification's made would be extremely useful to someone who may not be well versed in the myrad of issues with charging any android device.

I've had my axon 7 for 4 days. Good phone BTW. But this morning I woke up to charge my phone only to be woken up by the disconnecting sound. Battery at 30 and it refuses to go any more. Defect? I think so! Damn! Right when I thought this phone will be puuurfect. This happens I waited a long time to get this phone and now I might have to send it back

The AC charger is bad. No wonder for a 400 bucks phone they'll go after the cheapest brand they could to get us 3.0 chargers. Plugged it into my car this morning and it worked. Can I used the fast charger off my s7 edge? The input Is the same the output is obviously higher because it's 3.0 and Samsung one is 2.0. Will ZTE send a replacement charger? Or will I have to buy another. Says on the manual I can't use 3rd party charges too long or I can damage battery, guessing 20-40 cycles. Do I have to purchase another?

you can use any charger you want, but a Dash Charger from Oneplus because it's proprietary.
I personally use an Auckey QuickCharge 3.0 charger and it works great: https://www.amazon.com/AUKEY-Quick-...2-spons&keywords=aukey+quick+charge+3.0&psc=1
and the portable one too.

Ok .. wait... you like the phone ... the phone is perfectly ok ... it has a bad 5 dollar charger so you are going to send back the phone and buy a different lesser quality phone for higher price and .. well .. you may get a faulty charger on that one too .. or maybe even a faulty phone.... why take the chance .. just have ZTE replace the charger since the phone isn't defective. You do realize that you can charge it without QC and it is actually better because no matter what ZTE or anyone says .. QC will kill your battery faster than normal charging so QC should only be used if you need a quick boost and not to charge your phone on a regular basis. .. just use the little adapter they give you and your computer or an old charger you have laying around from your old phone and have ZTE send you a replacement for the bad charger you got.
When things are mass produced there is always a chance for a faulty component... and since the faulty component was the charger not the phone .. it seems kind of a foolish move to replace the phone if you "like it" .. I guess you don't really like the phone if having a charger go bad makes you want to switch out phones.

please state your sources, QC3 is different than raising the amps like the old times, it's a feature included inside the CPU, it's very different.
but I agree, to send back the A7 to get a OnePlus3T that he will get in a month if he is lucky, and since he is not, he might get a faulty one that he will have to send back to China and...

I'll just use my fd s7 edge till. I will be returning this device. It should work great out the box. No problems I will not buy another charger just so it won't work with this phone either. No AC charger works. Not to mention Wi-Fi has less range. Like I said I like this phone but I mostly like it for its sound. Wont keep it just because it sounds awesome when the battery wont charge. Not even going to deal with this sht I'll just get with a company I know makes quality products. Samsung never failed me, HTC either. Good luck guys.

Quick charging produces more heat than standard charging ... heat is what kills the battery. I have done more research and found that the heat caused by QC 3 isn't as bad as it used to be with prior fast charging methods and shouldn't really cause too much degradation of the battery. So if you are one of the people who replace their phone every year or maybe every 2 years .. then I guess QC3 isn't too bad.
If you are like me though, who doesn't replace their phone every year ... then QC3 may impact you if you use it for every charge. LOL .. my last phone before got the Axon 7 for replacement was a Samsung Galaxy S3 ... lol so I keep my phones for a long time .. The only reason I actually replaced the S3 was because I finally dropped it and broke the glass on the screen.

lol no offense but Samsung never failed you ???? you are lucky .. you bought a S7 edge instead of a Note.... Samsung .. a huge company failed a lot of people. But its obvious .. you are pissed off because a mass produced part went bad ... you are pissed because you had bad luck and got one of the bad chargers out of the 100000 chargers sent out. ... You act like the charger that came with it is the only way it can be charged and the phone is a paperweight because of this one small glitch that happens all the time and there is no way to control it.
No company can test every component they sell before it goes out the door... that would cost way too much and raise the price on the components way too much to be useful to anyone. As Samsung proves ... even big companies can have problems. Yes you got a bad charger .. just have ZTE replaced it .. im sure they would replace it without any problems at all. Until you get the replacement use either the cord from the Axon charger and plug that into your computer to charge it .. or use the adapter supplied with a charger that has a micro usb and charge it that way...
At least ZTE will deal with your problem ... I mean I have a Corsair AX760i Power supply .. it was over 200 dollars .. and supposed to be amazing quality .. well .. guess what .. it has a design flaw ... yet they still sell it even tho it has a known design flaw... they just don't care... at least with this ZTE .. its just a mass production issue.... its just a bad luck issue. .... they aren't selling defective products .... you just happened to get one out of thousands that prematurely failed and that happens to every product.

OK. So I've tried to use my s7 edge charger with it and it didn't work. Ironically it works with the car charger and it says AC charging but the phone displays a message to use the included charger for faster results. I come back from break and it don't work on AC, so in all honesty I would like to keep this phone but I think it's a defective unit. Not just the charger. So I'll contact ZTE to get a replacement because the phone is 4 days old. I will have more problems with a device like this if they can't do that I'll just get my money back. Thanks for your comments

yeah it may be an issue with the phone then .. I can plug my phone into my computer using the cord supplied with the original charger and it charges fine through my computer .. I can take my Samsung S3 basic non QC charger and plug it in with the adapter they supplied to convert it from micro to c and it will charge.. yes not fast but it will charge.
I would try plugging it into the computer and see if it will charge ... maybe the QC2 charger from Samsung just isn't compatible with the phone. .. for testing purposes tho .. i would try what I mentioned above .. using the computer with the supplied cord .. or using a basic micro usb charger with the adapter they supplied with the phone and see if it would charge... I guess if the only charger you have is the Samsung QC2 one .. I would try the computer with the supplied cord. I'm lucky I have a bunch of basic chargers lying around and they work to charge the phone without any problems .. yes its not quick charge but it still charges the phone.
If it wont charge when plugged into the computer ... or with a basic non QC charger and using the adapter to change from micro to c, then it may be something in the phone too ... but again ... these things happen with all mass produced products ... if you even have to do a full exchange ... hopefully you wont have bad luck with the replacement. My phone was fine out of the box ... as is with many others who bought it .. but ... again with all mass produced products ... it is always a crap shoot .... you can never say that each and every person is going to get a fully working product. Again to guarantee that they would have to test each phone and charger before packaging it and selling it.... and that would take many man hours and a lot of bucks so if they were to do that ... this phone would cost probably about 4000 dollars instead of 400.
I have to say I've had this phone now for a couple of months and I've had the s7 edge and s6 edge before that. I don't see the need for rooting the phones since i got the s6 edge onwards. The phones perform well out the box. But on all the Samsung's I've had from the original s series then the note series... There would be some sort of lag somewhere.... Though the Samsung's have improved recently... Still there is lag every now and then. This Chinese version Axon 7 i have is just totally lag free. It's on stock I've not done anything with it and it's working perfect out the box. I've got 2 sim and a 64gb sd card in it giving me a grand total of 188gb with dual sim. What can i say..... If they invest in some other features for the software... This phone can take over the smartphone market in a big way.

Coming from the HTC M8, the only difference that I noticed in wifi performance between the M8 and this phone is that the A7 takes twice as long as the M8 when connecting to a wifi source. When I say longer, mind you, I am only talking about ten seconds or so vs less than five for the M8. So, still not bad and totally acceptable. Once connected, the connection stays solid though. I am really happy with this phone. It is better than the M8 in every way. Beautiful design(esp. the front compared to the M8), newer and faster processor, bigger and better display, 4K recording, fingerprint sensor, USB-C, QC 3.0, dual SIM/microSD up to 256GB, Tmobile Band 12 support and, of course, the awesome audio/speakers. All that for almost $300 less than what I paid for the M8. This is without a doubt one of the best values in the high-end smartphone market right now. A premium phone but without a premium price.

What was the charging temperature? I think over 44°C it shuts off. I sometimes have big lags when I download or stream stuff while charging. I had two other devices so far, this newer device has a larger actual battery capacity than the previous one but has this heating behavior. I think this is due to having different voltage settings to ensure larger battery capacity since it is still directly correlated. The other device didn't have this issue and felt more fluid overall but battery was depleting a little bit faster.
It may be that your device has too aggressive voltage settings and it stops charging because of overheating. But it is strange that it happens while you don't use the device at all.
Can you install accubattery and check your charging stats, estimated battery capacity, temperature, etc.?

I received mine a few days ago and it won't enter quick charge and I have to jiggle the charge cable to keep it connected. Tried multiple chargers and cables. ZTE tells me it's a bad charge port or battery. Too bad it's a great phone otherwise. It will have to go back though. 15 hours to charge from 0 is not helpful.

I am. Sure replacement will be great. I had 4 devices and they were all great, so you were just unlucky. Compares to other brands I had before, quality has been very consistent from device to device.

Thanks. Sadly, though, it started out great, but then started suffering from the same issue as the first. It's not quite taking 15 hours to charge, life the first, but a solid eight or nine. Also, there is the additional bonus of white flashing horizontal lines every so often, until I restart the phone.
I wonder if B&H got a bad batch. I noticed two other people, in different forums that got there's from B&H, had the exact same charge issue. Strange.
I've been living with it, until I can get a LeEco to play with, then it's getting RMAed. Hopefully the third will be the charm!

Which version have you been using? This is something strange. Do you think B&H may be sending returned faulty devices to their customers? You seem to be amongst a tiny minority of people who have issues - such a level of faultiness cannot exist for any manufacturer, it just contradicts the principles of manufacturing smartphones.

First I had a gold A2017U. Then a silver one. I have also heard some people that bought from Best Buy and had strange issues. I can tell you both got a big shipment in right before Thanksgiving. I almost didn't buy the phone because they were both out. The suddenly that week they both had them in stock. As a side note the tech support person at ZTE mentioned he had a few people with similar problems and was going to swap it out without hesitation. Instead I just returned it to B&H for a new one.
My tinfoil hat theory, and I have a background in manufacturing as an engineer, is that they cranked up production to meet holiday demand and didn't pay as close attention to QC (ie what parts their suppliers were providing). But I have no idea. It's just heresy and anecdotes from people. ::shrug::

I should mention, I still love the phone, and have no I'll will towards ZTE. It's an amazing bargain, and the best no contract phone I've had, aside from the issues. I looking forward to getting a replacement.
