iOS 8: how to see which iPhone apps use the most battery power

September 17 was an exciting day for the millions of iPhone and iPad users. That's when iOS 8, the latest version of Apple's mobile operating system, was officially released. It brought along a generous amounts of improvements, both major and minor ones, and we already went over most of them in our iOS 8 review

There's one neat iOS 8 feature, however, that has not received as much attention as it deserves. That's the option to see detailed information about your device's battery usage – to see which apps consume the most power, be it while active or while running in the background. In this post, we'll show you how to access this data on your iOS 8 device.

Your iPhone or iPad's detailed battery stats are located deep in the Settings menu. Go to General > Usage > Battery Usage. At the top of the page you see how long it has been since you last charged your device fully, but that's nothing new. Scroll down, however, and you'll see a list with apps that have used any power over this time period. This should make identifying battery hogs pretty easy as they'll be listed at the very top.

Wow, that's complicated as all hell. Apple needs some help from Google software designers.

It's worthy to point this out because this is so groundbreaking for apple.

Google's (or android's default) battery stats in the settings aren't really useful because they show all the wakelock battery drain under android os and it becomes difficult to understand which app is causing those wakelocks(wakelock detector is the right app for those stats) If ios 8 battery stats display the wakelock battery drain in the respective apps then i think these stats are more useful than google's.

6 steps? On Android it takes 2. Well done Apple. Only took you 7 years to badly implement this feature.

iPhone came out in 2007. The first Android a year later. I honestly don't know what version of Android featured battery statistics. But it was irrefutably at least a few years before Apple did, and there might have been 2nd party ROMs and/or 3rd party applications that were available before Google implemented it themselves. Regardless, Apple is years behind with this. YEARS. A year is a long time in tech, and they're YEARS behind. And this one feature isn't the only thing they're behind on.

Isn't there something similar to GSAM on the iOS platform? On my Droid Razr M and Moto X along with various HTC devices the information can be had very quickly. Quite frankly too many settings are buried within the Settings box on iOS. It was a bit annoying to dig through various things on my iPod Touch and iPod Nano (not iOS but still related).

No there is not. iOS is locked down. Developers can't monitor battery usage by the phone and other apps.

Unfortunately, even google is locking down android slowly...in the earlier versions of android, it was really easy for any app to detect the per app kernel wakelocks...after android kitkat, you need to root the phone to get such stats....so developers can't monitor android kitkat's per app battery usage( because for that, you need to monitor kernel wakelocks).

A revolutionary feature indeed! Who didn't Google think of that?!

One button to save power on iOS. Press power off and you'll have your life back as a bonus.

I think you'll find Symbian had this feature long before Android did.

Ya got that right. I'm an Android fanboy, but the menus on the GS5 are craptacular. TouchWiz is awful. Just awful.

Yup. I always keep tabs on android as it's an amazing OS. But if I go android...it's nexus.

Well, you joined 3 days ago and asked a stupid question without any indication that you were being sarcastic. So yeah, I thought you were that dumb.
