I too, have had this issue. I have narrowed it down to Spotify that is causing this issue. I used to leave Spotify open 24/7 on my iPhone4 and it was never an issue, then on the 5 i noticed my batter was at 80% after 2 hours (And I wasn't even listening to music, just had it open in the background)
I closed spotify the next day and my battery never fell below 70% all day long.
I hope there's a fix for this soon, as I use my phone for work and if I forget to close the app I'm going to be in a ton of trouble with a dead phone and no way for my clients to get ahold of me.
This has happened twice..today Spotify app killed my iPhone 5 battery from 90% down to dead in less then 2 hours. Instantly I knew something was up with the Spotify app as battery is fine otherwise even watching YouTube for an hour takes off about 19%
i am a premium user. I was listening to online spotify. I had my phone screen locked so display was off.
I would try and re-install Spotify but then i will lose all my downloaded playlists 😞 so looks like the app needs an update fellas 🙂
btw I fricken love Spotify thanks for an excellent service
Although I do believe that the current version needs to be looked at for battery drain, I have found that what has really helped me to maintain battery life is this.
Whenever I do NOT need to use data I simply go to GENERAL / CELLULAR DATA / and turn it off ..then if I need to access the web I turn it back on. You can still recieve calls and texts with the cellular data tuned off.
This is what i found to be the main culprit of the iphone 5 battery issue.
So if you listen to Spotify offline... try this method and let me/us know your resluts here.
For me .. I have been able to retain MUCH better amount of battery life.
Thanks for the report guys. I'm experiencing this as well myself, not entirely sure it's Spotifys fault since I've spoken to a few about battery consumption using Spotify and they're not experiencing any differance from iPhone 4S to iPhone 5.
I'm looking out for more reports on this, and continue to test this myself. if it really is an issue there should be more incoming reports on this soon.
I have the same trouble myself, iPhone 5 , battery drains out, listen to music for about 45-60 minutes drains my battery about 20%, no other online streaming does this, the rest of the day I was listening to various podcasts, and the battery was fine.
The only app that drains my battery that fast is Spotify, I even tried with offline playlists with no luck.
I also have an iPhone 5 and all of my playlists are offline. I am also using offline mode inside of spotify. I had the app open all day but not playing and battery was fine. Once I started playin music battery drained at 30% per hour. Also iPhone gets really hot.
