I have been using Amazfit Stratos for almost two months without any problems, until today. I put it in the cradle trying to recharge it, but the charging screen didn't show up. I went and connected it to the PC, Windows 10 shows no sign of any device connected to the USB port. So, I started eliminating causes one by one and what I tried so far is:
- cleaned up contacts on both cradle and the watch (wooden toothpick with insignificant amount of isopropyl alcohol), nothing chaged
- checked the voltage on the cradle contacts, there is cca. 5V between the first and fourth contact, so it's not the cradle
- tried three different power adapters, plus a powerbank
- reboot or power off did not help either
- 5V directly on the watch contacts (#1 and #4) with an old USB cable, still nothing
- adb devices => no device listed
- in despair, I unpaired the watch, no charging/USB detection yet, paired it again, no change
Anyone else with the same issue? Anything else I can try?
BTW, I found some Youtube teardown videos, where folks are showing that the contacts inside the watch (between the surface contacts found on the plastic cover and the PCB inside) can corrode, but to fix that you must open the watch (it was for Pace actually, but I suppose it's all the same for Stratos). To do that, you need to apply force and probably say goodbye to water resistance, and many other things can go wrong, so I see that only as a last resort.
As you already tested the charger and it's OK (5VDC reading between first and last pin), then if you press and hold the top button for about 10s to make sure it is off and you leave it charging for 30min and you don't see the battery icon when you press the buttons then it's a hardware issue and you should ask for a replacement.
Thanks for the suggestion @lfom, I will try that and get back with the results. Is there any explanation behind this procedure you're proposing? Could this possibly be a software issue?

The only thing that is needed to display the battery icon is the bootloader (U-boot) which is hardly affected by anything else. If you are sure the watch is off by pressing and hold the button for more than 10s and it won't display anything while charging, then it has an internal (hardware) damage.
Power off Stratos prior to charging
There's a software bug I reckon. I am having same issue. Workaround is to power off the watch each time prior to charging from cradle.
in my case the charging screen appears but charging is very slow 1% per 30 minutes, do u have any idea what it is?
tried everything but it isn't charging.

in my case the charging screen appears but charging is very slow 1% per 30 minutes, do u have any idea what it is?"
in my case shows the battery level as if its charging but doesn't charge at all. tried charging through pc but it keeps debugging out
the same problem I have too. I did all the things but in vain
I'm waiting for the solution if some one can help us please....................
@azhar63 There is no "miracle fix", only workarounds: try to turn off watch before putting to charge, some people reported it help. If even then you cannot charge your watch even with a known working charger, you must open it to fix the internal charging contacts.
@lfom
for mine it now doesn't show battery single as if its dead.
it this issue because of the contact of battery ports?
is there any video to open up and fix it??
waiting for solution please
OK

Thanks a lot to reply
actually the device is already powered off. Some time when I try to charge on PC or with charger is shows 0% charging and after few minutes or seconds it disappears. I have two original charging dock & I checked voltage too, but I think the problem is inside of device. Anyhow I'm sure I'll get help soon.

If you get the 0% and then it dies, then maybe the power source you are using cannot provide the current needed, or the cable/cradle has problems (too much resistance), even if you can read 5V without the watch connected.

Press and hold te top (red) button for around 10s to make sure watch is off and then put to charge, then briefly press the same button after 30-45min. If you don't see the battery percentage on screen, probably it is dead or has a bad connection internally. I think the procedure to open it is the same as PaceL heat to soft glue then open it. You can look for FCC pics of it opened, it may help, I don't remember seeing any videos opening Stratos, only Pace.
I have the same issue
I have tried with different craddles and power adapters, with the watch powered on and off; on all the cases, no battery icon shows on the screen.
I think is a hardware problem with the pins of the watch.
Can anyone give the instructions to unmount and reseal it again after that?
Thanks

My battery's been on the fritz for the last days now. Whenever I turn my GS2 off, it will shows tha battery charging screen, then flash to another icon that shows a battery, exclamation mark in a yellow triangle, and a thermometer. It had to plug the charger in to get it to turn on, even though battery was at 100%.
So, I decided to download Battery Doctor to check my batter stats, and it says 'Health: Over Voltage'.
Does anyone know how to fix this? Help would be much appreciated.
I have exactly the same problem. I have not found a sollution, am thinking of calling samsung and explaining the situation. I will post here if i have a sollution.
What OS version are you running?
What Kernel version are you running?
What carrier (if any) did you purchase the phone through?
I'm on 2.3.3 (KE7), using Chainfire's kernel. Phone is carrier unlocked, unbranded from clove.co.uk.
Btw, I think I may have fixed it. I discharged the battery and used a charger with a lower voltage output to get it fully charged. (Charger I used if from my spare phone, a Samsung Champ). It now says that my battery health is good.
Now, the problem is that my phone won't stay powered off when I turn it off. It will stay off for 1-2 secs and power back on. Even if I remove the battery, the phone will power on after i place the battery back without me touching the power button.

I have the exact problem. Is the battery health still good? I would like to fix this by myself and not send it in and be without my GS2 for that time.
You should try this:
1. be sure, that your battery is full (charging over night)
1. run the app battery calibrator
2. unplug charger
3. drain battery all the way down till it shuts off
In this way your phone can remember what is 100 % and what is 0%
My sgs2 shows 4,194 V at 100 %
I think your stats (look into battery calibrator) said that 100% are for example 3,8 V
PS: You need root permissions
---------- Post added at 04:55 PM ---------- Previous post was at 04:49 PM ----------
Please post us your current voltage.
I have this exact problem. Battery Calibration is pointless, we all know that.
Did anyone ever find out if this is fixable, or do I have to contact Samsung for a replacement?
It's quite annoying that I can't turn off my phone, it just powers on after about 2 seconds. In addition, I never know how much juice I have left in the battery as the reported capacity can jump from 90% down to 6% in an instant. After a reboot it might go up to 12% but I can still use the phone for hours without it shutting down...
Yeah
I've been having the same problems as all above...
Galaxy S2 on Sensation rom, but its not the rom, i flashed to another and the problem still remains...
It all started with phantom charging...(charging when the charger is not even plugged in and constantly making the "charger connected" sound)
I got the phantom charging fixed by cleaning the charger port with a cotton bud and some cleaning alcohol...But now i have overvoltage...
And just like the others, it'll stay on for example 100% and if you reboot its suddenly on under 10% and slowly works its way up to 20 or 30% without even being charged.
I'm assuming the battery got messed up during phantom charging, in tthis case calibration doesnt help, nor does flashing another rom. Flashing another rom leaves the phone stuck in MTP mode therefore unable to use it as a flash drive.
A vid on youtube reccomends replacing the part of the circuit board to which the charger port is attached and as well as the battery at the same time as the battery always gets messed up with the overvoltage issue....
When i have overvoltage i cannot charge even when its under 10%, unless i leave the charger in and reboot the phone it will then charge once it comes back on and it even says GOOD HEALTH until i unplug the charger.
I'd really like a definite solution to the overvoltage issue...
Bump!
Did anyone find an answer to this problem? Mine has started exhibiting the same behaviour. I haven't been able to search out any solutions...
Cheers, PF.
EDIT: Whoops! Just realised I'd better change that signature to SGS2-able. lol
I am also seeing the same issue for the past 3-4 days, I have switched off the phone and took out the battery, planning to visit samsung support center.
I hard rebooted the phone(which reset it to factory) that did'nt help.
will update once I get more info/help from Samsung support.
Vikas
i had the same problem as you guys and i fixed it by cleaning the contacts on the phone where you connect the charger. use some cotton buds and a needle and some alcohol and clean all the contacts at the bottom of the phone (usb cable slot).
make sure phone is turned off tho whilst doing it. that fixed my over voltage issue.
Hi Guys,
I went to Samsung Mobile Support Center today, they told me that USB mini port has turned slightly green, which means that it has in contact with Water
this will not be covered under warranty and might need to be replaced with charges
Tomorrow they will tell me the exact cost.
I still believe, its not an issue of Power port but with the battery port.
will update if I am able to get it solved.
It's a problem with your usb charging port. The only way to truly fix it is to have the charging port plus circuit board replaced. Happened to me a week back and I tried virtually everything- stock roms, removed root, replaced batteries etc. None of that worked. Some posts said it was a port problem. Went to a tech guy I knew and he confirmed the issue when he disconnected the port. It was relatively cheap for me to fix but some people have climed that samsung charges a large amount to fix it. You're better off trying to get it fixed on your own. If you're on warranty, try and claim it.
Also alot of people are having this issue- yours is about the 5th topic I've seen about this problem this week
Hi Guys,
My problem is solved. Samsung support replaced charging port and the chip it was in(total cost 650/- INR, about 13$)
now phone is working as before.
i have the same problem on my gs2, so can i fixed this problem by cleaning the mini usb port?

Cleaning the usb port will/might help with phantom charging , but not overvoltage.....
For Overvoltage you may need to replace the whole USB port part of the circuit board (easily obtainable on EBAY) and you have to replace the battery at the same time as well cause the battery (also easily obtainable off ebay) gets damaged with the overvoltage problem.
I have ordered both about a week ago, awaiting 3 weeks for it to arrive to my country.
Good luck with that...
Theres videos on youtube of how to do the repair for overvoltage yourself...
Will report back here if circuit replacement worked for me...

I just got in a nice Galaxy Tab SGH-T849. Which would be a LOT nicer if it worked..
I have done the rudimentary things. Checked the power plug and cable, cleaned the contacts, etc etc. No luck.
There is absolutely no response from the Tab. I had it charging overnight, so I know it has a good charge. Assuming it is capable of taking a charge.
I just wanted to know if there was anything else I can try before I tear into it.
Thanx in advance for any assistance rendered.

If you connect it to your PC, do you see any devices show up? If not, does it do anything if you hold down the power button for 10-15 seconds or so while connected? Knowing what devices show up can help diagnose what's wrong.

OK, that's bad. Sounds like it's completely dead. At this point, I'd take the back off and probe the battery to see if it has any juice.
To remove it, you've got to remove two screws from the bottom edge next to the accessory connector. Then you can use a spudger tool to remove the back cover. When fully charged, the battery should read 3.7v. If you don't have a voltmeter, you're kind of screwed. However, you can at least look around and see if there's any obvious signs of major damage.
If the battery's depleted, it's not guaranteed that it's bad - it's possible that the charging circuitry is dead. You can verify that the charge circuit is working by probing the battery with a voltmeter while the charger is connected.
Go to http://www.youtube.com/watch?feature=player_embedded&v=zslF7P5Wxcc for instructions on how to get to the battery.
Yea, I already have the back off.. The two screws on the bottom are of the tri-driver variety.. Check my tools to see if I have one of those.
Thanx again.. I'll check the voltages and get back..

Maybe the only thing to try at the moment would be the old battery drain technique... Usual means is to tape down the power button and wait days and days until it is dead, really dead ( shows nothing when connected to computer), then connect to wall charger and reboot and see what you get. This is really the ultimate "hard reset" but same result can be obtained far more quickly by removing the back and disconnecting the battery for a while to remove residual charge... Not as frightening or difficult as it might seem, have done it loads of times for various faults and to replace batteries in several tabs.

If you're trying to discharge by taping down power button just leave the tab on it's own not plugged into anything... Plugging into something that charges rather defeats the object of the exercise

In some cases it takes more than a day, be patient... Unless you are prepared to remove the back and unplug battery... The aim of the game is to completely power down the tab and remove residual charge in components, the "hardest" reset available.... So, two ways to achieve that is drain battery or disconnect battery... If you drain battery you must be sure it's empty to achieve desired effect then you obviously cannot restart it without charging a bit as the battery is empty, so you connect charger then try to boot, but the tricky bit is being sure the battery is completely drained otherwise you are just wasting your time... That is why battery disconnect is preferable

I had to purchase an iFixIt repair kit to get the correct driver to remove the two screws. I disconnected the battery, waited ten minutes and when I reconnected I was SO HAPPY to see the battery charging icon. I charged for a while a fired up the tablet. Everything was the same as if nothing happened. I am so happy because Samsung said they could fix the problem and it would be a flat rate of $150 which I don't have and I would lose everything.

It took me longer to remove the screws then anything. I stripped them and will need to replace them. I tried a regular screwdriver before the tri-wing screw driver and paid dearly in time. Once the two screws were removed, use a plastic pry tool starting on the bottom where the screws are because once the bottom and sides are pried lose, the top will slide over the extended audio jack.
1.5 hours to remove stripped screws
10 minutes to pry open
1 minute to disconnect battery (did not remove battery or three data cables on top of battery)
10 minutes wait for discharge
3 minutes to re-connect battery cable (it slides forward and snap down)
2 minutes to replace case

I've got the same issue as Lightside and the original poster. Mine is a GT-P7500, which had CM10 nightly ROM with CWM recovery. I sold it on eBay, but before selling, I wiped the tablet and got it back to the Clockworkmod main screen. I turned it off completely and shipped it to the buyer, ready for it to be registered by the new user.
The buyer received the tablet and from the e-mails I received from him in the first couple of days, all was going well. Then, a couple of days later, he sent me an e-mail saying that the screen shows the android lying on its back with "Odin download" mode showing. A day later, he sends me a messaging saying that he can't turn the tablet on at all. The guy who bought it is an old man and didn't know much about fixing the issue. I asked him whether he powered the tablet off while still plugged in to the wall charger and he confirmed that he did. I asked him to return it to me and I can try and fix it, so now, I have the tablet back and it won't turn on. Here's what is happening:
1. I drained the battery using the cellotape method
2. Installed the NVflash drivers
3. Waited for the battery to drain (almost 9 days and the LED flash stopped blinking, so assumed it was completely drained)
4. Plugged it in to the PC and it immediately showed up again as a device under the USB controllers within Device Manager
5. I then unplugged the battery by opening the back of the tab, left it for 15 mins, then tried the wall charger again, but nothing. No charging icon on the screen.
When I try to press the power button, I can see the LED light up, but the screen is still blank.
Could this be a hardware issue and if so, what do you think could have caused it?
Could really do with some help here, folks! I don't want to have to give the buyer a refund because technically, he got it when it was in working condition and he probably did something to screw it up, but since he's an old man, I thought I'd try and help him, if I can.
same to me

I've got the same issue as Lightside and the original poster. Mine is a GT-P7500, which had CM10 nightly ROM with CWM recovery. I sold it on eBay, but before selling, I wiped the tablet and got it back to the Clockworkmod main screen. I turned it off completely and shipped it to the buyer, ready for it to be registered by the new user.
The buyer received the tablet and from the e-mails I received from him in the first couple of days, all was going well. Then, a couple of days later, he sent me an e-mail saying that the screen shows the android lying on its back with "Odin download" mode showing. A day later, he sends me a messaging saying that he can't turn the tablet on at all. The guy who bought it is an old man and didn't know much about fixing the issue.

Thx, i will try to night and let see it after 24 hours charging ..:good::fingers-crossed:
For now, it still dead. Can't turn it on but the screen pretty warm.
I think I had that happened after my five days of use. It didn't turn on even on the charger for few hours. What I did was holding the power button for three or four seconds, and let the watch turn on the boot screen, and then right away put it to the charger. Then you should see the battery charging status image on the watch.

In my case i didn't see any boot screen when i hold the power button. you have any idea to turn it on?
Try plug your charger directly to a power USB switch. and clean the pins on the charger and on the watch.

Oh, really. be care ful bro, i so concern your watch will dead as my watch.
My battery is completely 0%. My watch is not turned on even on the charger. I pressed the watch down to the charger and made sure it was touching the pins, and then I pressed the power button the watch (while it is on the charger) for 2 or 3 second; the watch is turned on with battery charging status image. Hope that helps. BTW I use a StartTech USB switch for charging my phone and watches. The switch is not plugging to a PC or laptop; it is only for charging my devices.
After I "fried" some bluetooth headsets with wallchargers ( probably powersurge or similar )
I never ever use them for "small" devices like headphones or the watch.
I always charge with a powerbank.
Since then I didn't have any problems
Try to twist the charging ring
After I twist the charging ring couterclockwise/clockwise, the power was increase. So you should try twist the ring until it got the right position and precise contact. Hope this solution helps yours.
I had this exact same problem with my watch after about 8 days, i had charged it multiple times before but one morning i noticed my watch completely off and thought the battery must of drained completely. I went to plug it in and nothing happened it wont charge (even leaving it on the charger for 24+ hours) . Ive tried everything and it just wont turn on or charge.
OP im afriad yours sounds like same issue, i raised a dispute on Aliexpress and got a complete refund. I have just recieved another one so im hoping i dont have the same issue again.
I still have the old broken one so was tempted to pull it apart and see if i can see anything but tbh i wouldnt know where to start so have not bothered.
Try washing charger and watch contact point

Hi guys
I think I might have fried my Pace. As I can read in the many threads on the forum a lot of you have seen problems with the Pace not turning on after recharge. On a visit to my family I needed to recharge my watch and I used the cradle with a wall plug power supply. Upon charging I did notice the screen was flickering a bit, but I had to leave the house. When I got back a littel later, the screen was black and the watch would not turn on. I havent been able to turn it on since. Using the USB the pc does not register anny devices nor does ADB or fastboot.
Is the watch dead? or is there something to do?

Did you try cleaning charging pins with a toothbrush or a toothpick? I had the same problem as you and I solve it with this method.
Hope it works to you, regards.
Thanks arceoxis
After reading all the threads on the subject it was the first thing I did, but unfortunately unsuccesfull.
regards
