The Rezound can use lots of power with everything running. In fact, it will use power faster than a connected charger is capable of keeping the battery charged. The problem isn't with the amperage of the charger--its that the phone's internal charging manager isn't capable of utilizing power from ANY charger to charge the battery as fast as the 1080p screen, 4G, GPS etc. is capable of using it up.
I've got an extra phone back. I'm thinking I'd like to mod it into a battery eliminator. I'd like to have an external power supply that the phone uses INSTEAD of the battery when the moded phone back is in place.
Does anyone know what problems I might run into? I'm sure putting the battery charging process in-between the charging cable and the phone buffers the power and smooths it out but there should be a work around.
There are 5 little unused spring-loaded contacts next to the internal Micro SD card. I wonder if a couple of those might already set up for the purpose.
Does anyone have some ideas?
