After KitKat overheat with magnetic charger, someone else? topic

Ok So I bought some adapters (see attachments) to charge mi Z1 via the magnetic port, So far I dont have problems, until the KitKat update, in all JB versions I can charge it without any problem, I have one charger in my room and I use another for the school (different cable, different power source, different adaptor) But after the KitKat update there is a point (mostly when the battery reaches almost 50%) when the phone starts to get some overheat, there is even a point when stops charging (maybe for security I suppose, so I left it in the night and when I wake up the battery is at 60% + -, and the phone its hot as I was playing with it, it only happen via the magnetic and only with the kitkat upgrade, anyone else having this behaviour? I have do a update via PC Companion, and after notice these behaviour, a complete wipe with SEUS, same results

any idea? :(
