Finally I have recognized, that the original in box charger cable had to be changed (repaired) due to very bad built quality and was not able to charge the watch. I highly recommend to you to do the same. I have no more problem anymore.
Happy :-) I had to change the original charger cable. With new one works perfectly. The cable original attached in the box was a crap after some months. :-(
Few months before, my Amazfit gtr started taking too much time to charge fully (about 10-12hrs). Sometimes don't even see any progress in charging for the first few hours. After couple of weeks it only shows charging animation but won't charge. Finally the charge on the watch completely discharged. Now when I keep to charge the watch, no charging animations are seen (blank screen) but after couple of hours, amazfit logo will start blinking at regular intervals. What could be the problem? Please reply🙏
@@SPAN25 yes it is enough. Do you measure at charger or at the end of the charging cable? However it can happen if the cable is faulty unloaded voltage is enough, but if you connect the watch the current drop will be high and the voltage falls in that case. Seriously I propose to check with other cable I did it same and now I have no charging problem.
