I am wondering if anyone else tried to measure the Bundled S5 charger performance. Anyone?
I got my S5 on the first day it was available locally. Then I tried to measure its charging and was surprised to see that the voltage was much higher than usb specs. I am wondering if it is still safe to use 5.6-5.7V charging mobile phones. I think 5.3v is still on the safe side, but I think 5.6v is stretching too much. I'm guessing Samsung used 5.3v to hasten charging a little bit (A x V = W), but was also surprised that S5 saps only 1.75A even though the bundled charger is rated as 2A @ 5.3v.
I know that the charger should output less than 5.3v when a device is attached because of the power load. But it seems that is not the case.
I haven't used my S5 charger frequently, I still often use my S3 charger and my powerbank which are only giving out 5v.
I am asking here first before I go to Samsung Store and try to have it replaced. I don't want to waste effort going there if all S5 chargers are the same anyway.
I am unable to directly post links, so please see the attached image and the youtube video with the video ID.
