    Is anyone else experiencing battery drain from Pandora? I'm on an iPhone 6 Plus. This seems a bit much for only an hour of use while the screen is off. [​IMG]

    What do you mean ? It shows precisely what you said your usage was. 1 hour in the background with screen off. If you mean the % it's also at the top compared to other apps and all of them combined make 100%.

    I mean Pandora shouldn't take 37% of my battery with one hour of use?

    I'll admit that I don't know the iOS algorithm of how it weighs those battery statistics nor in prior versions, not now in iOS9, where it shows background usage as well. But let me think a bit.

    I'd suspect that it puts more weight to a process which is continuously running for a period of time in the background, not in short bursts. For instance the Ringcentral app contributes to much larger time in background over 24h, although it only got 2% score. Another point would be how recent was the process measured, since the whole data set displayed is "in last 24h". Now if Pandora would use same amount of background time over 24h, the % might be lower, but the time would be the same. But you said you used Pandora for 1 hour, then checked the battery stats, which attributes for it being a more recent process, therefore getting a higher % score.

    Then there are also other factors contributing to the score as in which and how much resources are used by the process, like cpu frequency, audio, wireless/mobile data, etc.

    Did you notice how much of actual battery % was used in the time Pandora was playing ? That would be a more decent indicator of possible weird drain. I notice you don't have the battery % enabled for the indicator top right, set it to play for an hour and check how much % it drops.

    That is very strange. Even streaming shouldn't take that much.

    I'm not quite sure what you are talking about, but the timers start after a full charge. So in the morning I start out at 100% battery. As you can see throughout the day my battery is low, and it is showing that Pandora has used a significant amount of battery life in one hour of background usage since the last full charge.

    I ended up killing all the background apps (there were a ton) and hard reset my phone. It appears to be back to normal.

    Technically it's not from the last full charge, but from the last 24 hours.

    Yes I've been experiencing the same thing too! It only started a few weeks ago, but while streaming Pandora through headphones while the screen is off and all other apps are closed out. Restarting the phone does nothing. I lose roughly 20% every 15 minutes.
