Hello all,
My stratos was working normally, but yesterday when reached 9% of battery I turned it off and put to charge using a wall charger (Samsung Galaxy S8).
After a couple of hours the watch didn't turn on and nothing is showing at screen. Completely dead!
When plug it to windows only shows "A USB device descriptor request failed."
Can't put it to fastboot mode.
I bought it from AliExpress 6 months ago (can't request a replacement anymore).
Thanks for any advice.
EDIT 1:
When I leave it plugged into the notebook, it gets warm.
What is the voltage rating on the charger you used? If it anything more than 5V, you fried it.
The S8 charger is 5v at 2amps, thus you fried the charging controller on your watch. Nothing else you can do.
The smartwatch, like all the other mini battery devices, are made to be charged at 500mA, aka the amperage a desktop/laptop USB normally outputs.
The problem is not the 5V 2A of the S8 charger but the fact that it is capable of fast charging. It can also output 9V 1.67A and that higher voltage must have damaged your stratos.

Thanks for all the replies...
So, now I can only throw it under a truck, can I? :crying:
Voltage is the important factor. With the correct voltage the watch will draw the Amper it requires.

I purchased a new vent holder with a car charger, and it charges the phone up OK when it is off, but if it is on it says charging but does not actually charge. This is especially annoying with Satnav and after an hour or two the phone dies and I don't know where I am going!
Anyone know what causes this? I guess it can't provide enough power for the device, especially when using the internal GPS, but I think it doesn't even keep up with the device is just turned on.
I am getting another charger just in case, but never had the problem on my old Touch....
..
try -> start/settings/system tab/power/battery tab - uncheck the box "when the device is turned on...."
It isn't ticked...
..
try ticking it..
That will have the opposite effect, it charges fine when plugged into the wall, the problem is something to do with the car.
Does anyone use satnav on a touch HD and have it charge at the same time?
Well there could be one or two issues.
On the USB port there are four connections, a positive and a negative and two data pins. When you plug your Touch HD into a PC power is supplied down the power pins and after negotiating with the USB controller chip over the two data pins the phone will pull up-to 500mA from the power supply to run and charge the phone. This is so the USB port on the PC is not damaged by the phone overloading the power supply to the port.
Without the negotiation with the USB controller chip the device will only charge at 100mA.
But 500mA is not enough to charge the phone with everything running, you will need at least 1000mA to do that (1 Ampere). So that is what your wall charger pushes out. But how does the phone know it can charge at a higher rate? Well inside the charger the data pins on the USB connector are wired in a way that the phone 'sees' that a higher current is available, and pulls a higher charging current.
So what you need is a minimum current 1 Amp car charger. If you already have a 1 Amp then the chances are that is does not have the data pins connected properly and the phone will not draw the higher current, meaning it will only charge at 100mA.
Thanks, I am going to try another one and see if that helps, perhaps it is just faulty, otherwise I will check if it is 1Amp.
Cheers.
I contacted the seller and they sent me a new one, which works. So it turns it my charger was just faulty.
What's the rating of the new one? and where did you get it from. I bought a 2amp (supposedly) but it doesn't give me more than 500mA.
I've had this problem and it sucks! As I'm always out on the road. But I have found a few solutions. I purchased a mini usb charger from asda for £6. After adjusting the backlight to medium this charger seems to keep the power level the same as it was before you plugged it in, so It doesn't let the battery go flat. I've now learnt to keep a spare charged battery in the car just in case it fails.
Hey guys,
I was wondering if these USB car chargers are compatible for the TP2?

I'm asking because I remember in the past I used a HTC charger to charge the O2 XDA Flame and it charged. However, the phone started acting VERY weird and freeze a lot. I ended up having to hard reset it
Thanks!
I think any USB charger for electronic gaget that has a output of 5.0 v should work. It does not matter if it is an AC charger or and car lighter charger. I got one of these AC and another car lighter charger. There are all 5.0 v output. I use them to charge Ipod and phones.

It's best to choose one that can supply enough current (I think the wall charger supplies 2A, but 1A should be ok). Some devices will still trickle charge with a lower current, but others just won't trigger the charging circuits at all.
I had a cheap car charger that seemed to work ok most of the time, but it got worryingly hot after a while.
My TP2 came with an official HTC charger, so I use that now and it's great.
I have noticed that if the phone is OFF then 1A is not enough and usually stops charging but if the phone is ON it completes the charge..but takes for ever.
Has anyone experienced the charging overheat situation where the led flashes orange and green? I dont know if that is the situation but it only happens when I am charging in the car and the unit gets hot.
My old "OEM HTC" charger I got on ebay (the one with the blue HTC light) just stopped charging my phone after about 10-15 uses.
It lights on (charger), but my phone doesn't catch any charge lol
I got a 1A one, and unfortunately it cannot produce enough juice when running the GPS (copilot), after a while the phone shows a message telling the charge current is not enough.
The wall charger that came with the original box is 1A too, thus the problem might be with the cheap car charger.
Brando sells a 2A car adapter that should do the trick. They're out of stock right now, but it may be worth a look.
Hey!
Mine is a cheapo but does the trick. Charges the phone with satnav running, today went from 23% to full in less than 3 hours. Plus it's really tiny so I can keep my ashtray closed all the time. Using it with mini retractable cable, it all fits in the ashtray and it's handy to use.

The manual states that the output of the AC charger is 5.0 volts and 1 amp. That means the output of the DC/car charger should be the same. Using a 2 amp current might be charging the device faster but it would probably generate more heat and might shorten the battery life.
one tip, regardless of which charger you end up with, is to not leave the phone plugged in while starting the car. my understanding is that there can be be large voltage surges or fluctuations during the startup. depending on the design on the voltage converter inside the charger, some of that may be making it through to the phone.
i once had a AA NiCd battery smart charger that went wonky after using it in the car a lot, but that was with a straight-through 12V car to charger connector.
I made my own charger for using as a GPS on my motorcycles.
There is a charge select line in the plug. If the phone detects that it is connected to a USB port, the phone will not 'pull' more the 500ma. If that line is set to indicate a non USB port, then the phone will pull 1 amp. MAX (I never saw more then 900ma myself).
If you have the wrong charge plug, it may only charge at 500ma. If you have the correct plug and the charger can manage 5 amps, the phone will still only take 1 amp max.
For a while I used the phone in a waterproof box called an Aquabox. It would overheat during charging. I now only charge the phone when it is not in an enclosed hot space.
I'm still using the off-brand 'for Blackberry' car charger I got back when I had my Kaiser. Seems to be working just fine with this phone as well.
The thing is.. When I use original charger and original cable I had with phone in the box, it charges so slowly it can actually discharge while for example using skype.
Also funny thing is in settings/more/battery (android 4.3) it shows Charging (USB) when I am connected to the wall socket. The app "Galaxy charging current *lite*" shows it is receiving 460mA right now at average. It takes like whole night to charge. (at the time of posting it was 460mA, but I have to notice ,that using this original cable and charger from wall socket, phone itself somehow changes how much mA it takes as it varies from 100 up to 500 from long time observation)
When I use small micro usb – usb cable from my old Nokia 5800 Xpress music, it is charging at 1000mA and can charge even when using skype or anything else. With this cable I can charge from 0% to 100% in about 1-or 1,5h. (Here it is always constant - 1000 mA on average using that app)
I was googling and reading some posts from people with some S3 charging problems, and found that cables are the reason. I have noticed by visual comparison of S3 original cable and nokia cable that on the micro usb side, S3 cable has visible only 4 pins but nokia has visibl 5 pins.
1. Is the pin amount on usb micro side the reason for slower charging rate ?
2. But why the hell my phone thinks I am charging from USB when it is connected to wall socket when using original cable and charger ?
3. Is it safe to use that nokia cable to charge my phone ?
Thank you for replies !
Throw away the faulty charger, rating of the replacement is irrelevant as the phone controls the current used.

Hi, thank you for your reply. I apologize, may be because english is not my mother tongue, I do not undesrtand clearly what you are saying. Especially this part "rating of the replacement is irrelevant as "
May be I described my problem not accurately. I attached the photo of things I am writing about. I use still the same charger (number 1) I just either use original samsung cable I had with my S3 (number 2) or original nokia 5530 micro usb cable (number 3)
With S3 cable and original charger (1 + 2) it charges slowly and app in phone shows it gets at maximum 500 mA. Full charging (from 0% to 100%) takes about 8 hours at least. Also, sometimes the phone shows its connected to USB, although I am connected to wall socket. The thing is, that even when it shows AC, the app in the phone still shows it is getting somewhere between 100-500 mA. So charging is still slow. I have also noted, that current changes during the cycle of charging. Or even when I unplug and plug the charger, it sometimes changes the current (mA shown in the app)
When I use Nokia cable (1+3), current is always 1000 mA. Charging time is something more than hour (from 0% to 100%). Using the same charger, just changing the cable.
So I am unsure if it is safe to use that nokia cable. Can it somehow damage my battery or phone ?
Is the behavior of the original charger and cable (1+2) ok ?
Throw part 2 away.
Part 3 will not damage your phone.

Hi all, I have problem with my HDX 7 Unlock BL and Recovery TWRP 3.0.0.
About from ten days up to now, my HDX 7 charge very slow with any charge HTC, Xiaomi, LG (I can not try with original HDX Charge which due to loss it some months ago). I use CM 12.1 dated 10 Jun 16 and also try all CM11 roms. When plug charge to HDX, I check information in Battery section of Setting that has report "charging by USB" but few seconds next change status to "not charging" and again and again.
What is the problem? How can I fix it?
Many thanks any comments.

My kindle charge slow and PC won't detect.
I have the problem that PC can't detect my kindle hdx7. And my tablet charges slowly with wall charger.
This is because one day I charged it with my Quick Charger 2.0. I think that was the reason, and charging circuit has been damaged.
Is it be a real cause?
Does any one has the solution?

Highly doubt the charging circuit is damaged. Nor is it likely a visit with the Quick Charger triggered the anomaly. Far more probable is a problem with the USB cable and/or the USB socket on the HDX. Loose connectors are common especially if care is not taken when plugging/unplugging. Lack of a data connection support this opinion.
Reboot your HDX and try a different USB cable. What is the wall charger rating (should be on the back represented in mAh)? 3rd gen HDX devices can accept charge rates up to 1800 mAH although using a 'stronger' charger won't hurt provided the voltage rating is the industry standard 5V.
Hi
Thanks Davey126

I purchased this tab from a local shop. I tested it on shop, everything was fine.
But when I bring home, and I connected it with my Sony QC 2.0 and I observed charging was slow. I ignored it.
Next day I connect with my pc to copy some movies, but computer didn't respond. I tested my tab with different data cables and on another PC, but no success. Then I did Factory reset, but no difference.
.
I went to shop and got exchange the tab. At shop I tested charging, and PC connectivity. Everything was working fine at there.
I got back home, and again connected with my QC 2.0 charger (until then i did not know the cause). This time I see tab show SLOW charging.
I connected to my PC, same issue, no any detection. Tab only show charging when connected to PC. I repeated all possibilities again to resolve the issue.
At last, I assumed that it was because it may be due to miscommunication between device and charger, and maybe 9V damaged the charging circuit of the Tab.

The Quick Charge standard allows for connection to older devices that do not support QC technology. In that case the charger should limit output to 5V as a significantly higher voltage would likely damage the charging circuit. Either the HDX did not communicate its capabilities properly or the charger cranked up the voltage when it should have remained at 5V.
The maximum charge rate for 3rd gen HDX device is ~9 watts (5V x 1.8A). Yet many vendors target this device for 18W+ QC 2.0 chargers that supposedly reduce charge times by 50% (they won't). Despite the faux claims there does not appear to be widespread complains of device damage. It would appear your Sony 2.0 QC charger may be defective.

Thank you for your concern and collect info about HDX7.
I am a little-known of Quick Charger mechanism. "9V or 12V and 5V". QC 3.0, 4 or 4+. [A Quick Charger does not damage a normal 5V device.]
I charge all my home devices with Sony UHC10 quick charger. I think my charger is working normal as I do not see any abnormal behavior of it.
.
I can not find any other reason to damage my Tab.
Now my question is that, "is there any (alternative) way to resolve slow charging, also PC sync.
Thank you again!

Recommend acquiring a 'standard' 5V wall charger with a 2A minimum rating. This will permit your HDX to charge at the maximum rate (~1.8A) assuming the USB cable is in good shape. Performing this test will help determine if the charging circuit in your device is operating properly.
Most computers/laptops can only deliver a fraction of the maximum charge rate: ~0.5A for USB2 ports; ~0.9A for USB3.

After realizing this problem I am using 2.1A branded charger, but still slow charging.
With Ampere app it shows max 280mA (same as UHC10). It means it is charging at standard rate of 500mA.
Changing the cables does not make any difference. (I have ANKER data cable)
THANKS

Anker cables have a solid reputation. That said, I would double check with another cable.
If cable and charger seem ok then it boils down to termination points (USB connections {should be snug}), imbedded charging circuit and/or kernel. There is nothing you can do about the kernel on a stock HDX. Nor can the charging circuit be repaired short of main/daughter board replacement.
Long shot suggestion: fully power down device and restart after 5-10 seconds. This will insure the bootloader/kernel are fully reset.
BTW - info I provided on QC standards and HDX capabilities are primarily from direct experience backed up by supporting documentation. This isn't just theoretical - I have a handful of HDX devices along with numerous USB meters as charging circuit efficiency (and deficiencies) is something of a personal interest.
@Davey126
Thank you very much
And big thumbs up :good:
I'll try it tonight and then update you as earlier as possible.
@Davey126
I drained my tab battery and then recharge it again but no difference. It woke up after 5 minutes. Still very low rate charging. Ampere app shows 280mAh maximum.
Meanwhile I brought my cousin's (same) tab. With 2.1A it shows +1500mAh on Ampere app. I drained it's battery, and when started charging, it was charging normally. Again in Ampere app @ +1500mAh.
.
I do not want to damage it's charging circuit. So I will not connect it with Sony UHC10.
So it is clear that charging circuit is damaged,in my tab.
If I find any solution, I'll share it here. Till then I'll use it by charging whole night (for 6 hours) everyday. Because it takes 6 to 8 hours to charge 100%.
.
Thank you for your cooperation.
Bought rn3
first time it fully charged in Little over 2 hours
I checked ampere app and it showed 1600-1700mA while charging
Then today morning again I put to charge with same official charger
and it doesn't charge !!
it shows charging but percentage don't increase
it sometimes even decreases!
I checked ampere app and now showing just 90-180mA current
I used a 1.5A Samsung charger and it charges with 750mA current
what's wrong?

Did you check if your phone still is communicating via USB? Because I have nearly the same issue.
I one wondered why my phone always was bringing this sound fpr plugging/unplugging the charger.
I assumed this was issued by a small charger which could not devliver enough current (usually up to 1800mA). So I used another one over the night.
Next day I expected it to be fully charged but it didn't charge at all. The app Ampere showed me just 100mA.
Then I've recognized that the USB-communication did not work anymore. So I guess that until there's no charger or PC-USB recognized, there's a limit to 100mAh.
I tested several chargers, cables and no chance to achieve more current. USB plug seems to be broken or something.
It doesn't matter if phone is powered on or off.
Then I've checked the Test-Menu. You need to shut down and then press VolUp, VolDown and Power all together.
Even from there I did not get any more current. And then I've chosen from Test-Menu the Reboot-Menu, choose Shutdown.
Now I got a 1000ma current!!!! Seems that somewhere the software restriction to 100mA is not active at this point.
Well, trying to fix this by getting the spare parts. First delivery did not fit. Second Delivery did fit, but phone did not boot.
USB-Plugin seems to be okay. the phone was a few days old.
I really don't know why anyone uses a 2A charger with this phone... Ideal conditions for charging a 4000mAh battery, or any other for that matter, would be 500mA to 1A current. I am using my trusty old LG 850mAh charger with this phone, and it charges properly, without heating up the battery. On the original charger, it went up to 38+ degrees Celsius. Now, it stays close to 30.
