Later today Apple will release iOS8.4, and with it we will get our first chance to have an extensive look at Apple Music.

There is one feature i'm particularly looking forward to - better battery life for my iPhone.

Apple Music will be in 256kbps AAC, as compared to my currently (maxed out at 3000 songs) Spotify library of 320kbps Ogg Vorbis music.

I spend a lot of time making sure RSSRadio's custom audio player is as efficient on battery as it can be, so i've seen the difference Apple's hardware audio decoders can make. I can well remember when I first used Spotify on my old iPhone 3GS that the battery life was particularly painful.

Over the years Spotify has definitely got better on the battery, either through advances in iOS, the iPhone hardware or optimising their decoder (probably some of all 3), but still i'm thinking that if you play a couple of hours of music a day you are going to notice the difference.

With iOS9 giving us an extra hour of battery later this year, and Apple Music helping along, maybe we won't be hitting that 20% battery warning quite so often?
