the battery isn't charging enough compared to the power consumption of waze+spotify+screen mirroring. While connected with the MHL cable, the phone is in mode USB charge and not AC charge/fast charge. I saw several forum threads with the same issue in MHL.
Does anyone here has the same issue or a solution ?
Just found out on some random article that there are 3 versions of MHL. And MHL 3.0 does allow 2Amps charging. That may be why I could not get enough power from my MHL cable even with my 3Amps USB charger connected on the fusebox. Just need to find a new MHL 3.0 cable then...
