Ok so is this normal for battery life, I was using pandora for 4 hours over wifi and bluetoothing to a speaker, phone went from 100% to 20%. There was very limited usage on anything else.
I didn't know you can use wifi to stream and Bluetooth at the same time always heard its one or the other
Streaming for 4 straight hours on what seems to not be that great a Wifi signal all while losing 80% battery seems pretty reasonable.
No it doesn't seem reasonable at all. 4 hours of Pandora, are you kidding me? I go all day streaming Pandora on my 6s. It routinely outlasted whatever Bluetooth speaker I had hooked up to it.
OP indicated a bad WiFi signal so that leads me to believe the phone is using more battery power for the struggling WiFi radio.
