When I turned it on the battery was at 50%. Choose a language, the settings and asked me to transfer data from my old phone with the cable, so I followed the quick guide and the transfer started. For 15-20 min, the battery was at 10%. - draining 1-2% per minute. I stopped the transfer because it was at 20% and started charging the device and installing the android updates. Is this normal or should I return it?
