I noticed it this evening, Spotify is a big drain in iOS8.
I've never had a battery issue with spotify on my iPhones. Especially now since the 6 has better battery life. It does use around 15% usage but I would expect it to since its streaming at the highest quality for me.
If you are going to listen to music at Extreme settings, offline or not, of course it's going to use 20-30% of the battery.
No drain here whatsoever.
I use spotify 2-3 hours a day, locally and use ~2% per hour.
You have a problem, unless your app is different to the UK version.
I can't have this app using 20% of my battery.
I like how we have the option to see what is actually eating our battery life with ios 8.
Im with you on that no matter how much I like an app if its draining my battery like that then I'd rather switch to something else and not bother using it any more.
The Spotify app on my iPhone 6 has 15%+ battery usage, even when I'm playing the music locally. This compares to about 1% usage for Google Play Music. Is this normal?
