Description: The iOS app drains the battery far too quickly! Even with offline playlists, flight mode enabled and no background app refresh, my phone will still die completely from 100% after 5-6 hours of listening and that's if I use no other apps. My iPhone 6 is brand new! In the battery usage Spotify is always ranked as the most draining app and generally shows something around 50% (unless I use any other battery-intensive apps, the lowest I've seen it drop is around 30% - still far too much). My phone never lasts a full day, without Spotify running it's fine! On iOS 9.0.2 I used to easily get around 10 hours from my year-old 5s with exactly the same usage (also now dies after 6 hours). It's shockingly bad but I dislike all other streaming services.
1. Play any music (including offline playlists)
2. None found, disabling EQ or audio normalisation makes no difference. Using an older version of the app also makes no difference.
