My friend rides with his iphone 6 plus on a quadlock mount as well as his Wahoo Element. Although it is GIANT, it's super sturdy, and survived unscathed from a crash on an alpine descent which left him with pretty nasty road rash.
Also battery shouldn't be too bad, as long as you load the maps before, and just have it using GPS whilst riding.
