Hey everyone, so I just got a transformer + dock from bestbuy and so far I'm loving it. I started reading through the stickies to learn more about the device and it seems like a lot of people are having problems with the dock draining the battery.
One thing I noticed about the dock when I'm using it is that it constantly uses its own battery to charge the tablet. Doesn't this mean that I can only use the tablet+dock as long as the dock doesn't run out of battery? Is there a way to stop the dock from charging the tablet so I can get more use out of "netbook mode?"
In other words, is there a way to manually tell the dock to start and stop charging?
Thanks everyone
The battery of the dock discharges only until 3%.
While docked the tablet is charged from the dock. The tablet uses the docks battery for power until the dock battery is empty, then the tablet starts using it own internal battery.
The idea is that the tablet battery is kept charged (or as charged as possible) while docked so you have a full battery on the tablet when you ndock it.
So based on these two responses it's possible to use the keyboard dock all the time without the dock becoming useless after a while? Just wanted to know just in case I need to use the keyboard all day
Yes, you can use the dock all the time, until the dock battery and TF battery are empty

From what I can see, when you have the keyboard dock connected, the dock will still continue to work even if its battery has nearly run down. This is as long as there's enough battery power in the TF's internal battery to power it just enough to use the keys and touchpad. The point it'll stop working is when both batteries are nearly out, in which case just charge them .
So, short answer is yes if there's enough power left in the TF itself.
[EDIT]: Yeah, pretty much what sr-ha said lol .
So if the dock continuously keeps the tablet battery charged even when it's at 100%, wouldn't that degrade the tablet battery? Or maybe I misunderstood, does the dock stop charging at 100% and power gets taken from the dock until it's at 3%?
I appreciate the responses, still a transformer noob

The idea is to keep the tablet at full charge so if you undock it is at the maximum level.
I think the Transformer just uses the dock battery when docked since you don't see the charging icon if the tablet is at 100%. The dock drains until its 3%, then the tablet battery gets used.
Is it really that difficult to understand? The dock charges the tablet. Modern batteries are computer controlled to not overcharge so this theory of degrading the battery by charging it too much or two often is a load of crap. No manufacturer would build anything that technologically stupid anymore. Especially not a top notch company like ASUS.
The dock will pretty much always work as long as there is a charge from something. I've never seen the dock go below 3% so I assume once it gets to a certain level it does draw from the tablet battery to maintain useability until the tablet and keyboard batteries are both depleted.

Exactly what I was thinkin'
Hey everyone,
Before my Transformer arrived at my door-step...I started reading around a bit more about spare chargers and such - and came across a few threads that people had had trouble charging their TF101 because the AC Adaptor was fried/dead/whatever.
I own the B60 version and all seemed to be going well until late today. I plugged in my charger as per usual...and no charging icon. I did a few plug ins/outs and swapping the polarity of the plug to no avail. I also tried an iPad 10W charger and that did nothing; proving to me that only the supplied charger or a 12V molex rail can charge the thing.
I then thought of any changes I had done to my TF101 over the course of the last 24 hours. I remembered. I had installed Clemsyn's kernel v9 on the Revolver 2.5 ROM. So...I thought about reverting to Netformer 1.6 kernel I was using before.
After flashing, it started to charge again. (Note: I did reboot the TF101 a few times before this to see if it was a Honeycomb issue).
This is a theory anyway....if the chargers are failing on stock ROMs and kernels...well that's ASUS' fault.
Hoped I helped anyone.
i don't know about this. I got a b60 also. The charger didn't work the first night I got the transformer. Stock rrom stock everything. I played around with the charger and it worked again. Now sometimes it works, sometimes it doesn't. Im on custom rom now and its still the same.

I was completely stock when my charger just stopped charging both the dock and the tablet. A few days later it started charging only the tablet and only doing that occasionally. It never did charge the dock again. It was the impetus I needed to finally RMA everything back to Asus for which I am waiting its return. It seems to me that this charger just can not be trusted and that is a big problem with a proprietary charger!

How many chargers have you owned, and how many of them have died? If it's a sample size of one, it's pretty-much meaningless. You only hear complaints from people who have a problem, after all.
Personally, I've used three chargers (mine, my wife's, my fathers) with three tablets and three docks, and none have had problems as yet (several months).
I have a B4O TF (fantastic BTW) and my charger died ...stock rom etc.
sent to asus...week later they still can't find my RMA (and I thought Dells customer service was bad)
I had already bought a charger for spare so I can wait
I bought a 5mm DC Female Barrel to USB Female cable - EBAY $2.99 and I'm always looking at chargers for it when I see one... Bought a I home 120V AC to 15VDC adapter at goodwill this weekend for 1.99 total cost of my new charger (others gonna stay in the drawer) 5 bucks and some change
find the Barrel to usb connector link and info about it in DevCake's thread here

i had the same problem with my charger month back when i got my pad. i called asus. it is a known problem. they sent me a new /replcemnt part for the charger. no hassles . ive been fine since
I experienced this same thing last night. I had flashed to Clemsyn's kernel Elite v12a kernel. I did a reboot however and charging resumed. I was having a hard time connecting to the computer as well. Perhaps, the kernel or settings still thought that the Transformer was connected to a PC because it will not charge from a PC unless the screen is off. There must be some script that is being interfered with here. Your theory may have some traction.
I was rooted when mine decided it didn't want to charge anymore, I had only had it for 5 weeks. I unrooted and even back to stock it still didn't want to charge. I sent it back to them and they fixed it after a week. Everything's been good so far.
My charger was working intermittently and I was near the point of returning the TF w/ dock or buying another charger. Then I tried running the charger thru a car power converter in my car and it seems that did the trick. Now it charges everytime, its worth the try.

okay so im not the only person here. my charger just stop charging yesterder. never rooted, always stock rom. i did factory reset, and still no good. now it only charges very slow, no charging icon showed. the cable is good, i can still connect to laptop.
The real question is: Is it the pad or the adapter? Because if it's the pad, that sucks big-time, if it's the adapter it is irritating but not a real problem, you could charge it via USB on your laptop/PC
I finally contacted Asus regarding to the faulty charger. And they told me to return the whole thing to the my retailer, because im still within the 30 day return period.

Charging via a PC is very limited. It will be very slow if it works at all. The charger provides higher voltage (15 vs 5) and higher current (1.2 vs. 0.5 amps). The charger and pad also expect the current on non standard pins association with USB 3 connectors.

Gotta be the adapter. I tried everything to get it working again, I noticed that when the screen was off, and I plugged it in, nothing would happen. But If I plugged it in to a smaller charge adapter, it would show the screen (as if something were connected), but not charge. So I tried my friends charger and it instantly started charging. However, After I charged it, I went back to my old charger, and it worked again. WEIRD! I have a backup adapter now just in case it happens again. Same thing happen in the past, It wouldnt charge (and I didnt have my friends), so I let it die, and charged it with my smaller adapter (which took like 1-2 hours to get 7%). Then I plugged it in again to my old adapter, and it charged it. It's almost like the charger reads it as full, and wont allow it to charge anymore. Then when some other adapter start charging, then it realizes it does need battery. No idea. Just my 2 cents.
Clemson Blades v.17 fixed it for me
Charging required a reboot after a certain amount of uptime. But, I also use Battery Monitor Widget's circle battery status icon. What was wierd is that sometimes the ASUS battery icon wouldn't show charging, but the circle battery status icon would.
Anyway, everything works for me now with Clemson Blades v.17. He specifically added in usb forced charging with v.17.
I saw the same problem with both ac adapter and computer's usb, but it was fine for a while after reboot but would stop working again after a while.

If anyone did a search, you would know that this is a common problem.
The trick is to unplug it for 5 or so minutes and it'll work again. Also, the writing on the plug should be facing up.

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...

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.

Thread #2:

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.

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.

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.

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.

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.

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.

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.

WiFi less range??
My WiFi is so fast at home, it's really amazing:

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.

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

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.
Hello everyone,
If you're unaware, there was a battery recall in 2015 about battery swelling. There was a battery modal and serial number of tablet that was targeted by the recall. Now, my tablet, 6 years after buying it, got a battery swelling problem. Found the battery poping out the back like hell (nearly double the size of the case!) Contacted nvidia support for help and just received today a tracking number for express shipping, a "new" tablet is on the way and no need to return the old one!
Now, yeah, it's an old 2015 tablet, who would be so in joy with that. I myself have many use for my tablet, like a monitoring for my computer, touch portal, home automation.
Now, I opened the back and saw the battery is soldered on the board. Not a big problem. MY question is, can the tablet by used without a battery like always conencted without a battery? I could salvage the tablet with the swallen battery and put it in a wall for home automation. I saw many person doing this but with a battery in it because "it's a built in ups", but having a battery always charging at 100% it's a big fire hasard for whatever device you use. I though about using some root hack to limit power charge to 50% but I never got to that part. Now, with that possibility of having a non battery tablet, that would be awesome.
THanks!
Maybe remove the battery and instead solder on a 4 volt DC power supply... That way you'll have an "eternal" battery and don't have to worry about the actual battery.
No idea if that would work, but maybe worth a shot?
You could always get a 5.5v "supercap" that they use for temporary memory retention and solder that where the battery was.
For example:
https://www.amazon.com/s?k=supercapacitor+5.5v
I'll have to try. I saw some old post where there soldered the red and black on the memory board. That worked but it bypass the usb and I'm using the USB. I'll check for the superap, maybe i'll work. I'll check for temperature at the sametime.
THanks
