Checking battery usage in iOS 8 provides basic statistics on what apps have been consuming the most juice. Under Settings -> General -> Usage -> Battery Usage top power-consuming apps in the past week or past 24 hours are listed. While this can be helpful, there are many battery details hidden from view.
The jailbreak tweak DetailedBatteryUsage unlocks these secret power statistics, adding a plethora of information to the Battery Usage area. Once installed, a battery level graph as well as background usage stats are revealed.
To some consumers battery life is one of the most important features on a mobile device. Apple claims that the iPhone 6 and 6 Plus get up to 10 hours of internet use on LTE and up to 14 hours of talk time on 3G. If you are finding that your new iPhone is falling short of Apple's battery claims you may want to check the new battery usage tool found in iOS 8. Just navigate to Settings > General > Usage > Battery Usage and you'll find a list of apps and how much power they're each using.
The battery usage tool shows you the apps that have used the most battery life in the last 24 hours or last 5 days. The knee jerk reaction would be to eliminate these power sucking apps, but just because they're at the top of the list doesn't meant they're evil battery killers. It just most likely means you use them a lot.
Older devices are no stranger to battery issues. As iPhones are charged and discharged, the battery will naturally lose some capacity over time. Apple has recognized that a range of iPhone 5 units with specific serial numbers can suddenly loose their charge.
For those experiencing the problem with their iPhone 5, Apple has offered to replace the battery free of charge. Since a specific range of serial numbers is affected, the company has set up a web page that makes it possible to check your device for eligibility under the replacement program.
Another photo of purported iPhone 6 hardware surfaced today, this one showing what appears to be an upgraded battery for the highly anticipated handset. The photo, spotted by French tech blog nowhereelse.fr, comes from a source in China. As always, take it with a grain of salt.
The battery in question is made by Desay Battery Co., which has been rumored to have ties with Apple regarding the iPhone 6. The photo shows that it has an 1,810 mAh (milliampere-hour) capacity, which is up from the current iPhone 5s' 1,560 mAh battery. The current battery offers up to 10 hours on LTE and 250 hours
The idea of disabling LTE on your iPhone may sound a bit odd to some, but not everyone needs 4G data speeds, and it can also be a bit of a drain on your battery. This is especially true for AT&T users whose phones tend to jump back and forth between 4G LTE and HSPA+. If you are out and about for a long trip, and don't need fast data speeds, it is may be a good idea to disable LTE so you can get more life out of your battery. Here's how:
Open your Settings app and tap the Cellular tab to open the cellular options on your iPhone. From here you can disable Cellular Data, LTE and Data Roaming. Just tap the "Enable LTE" slider so it turns white to turn it off. Just don't forget to turn it back on when need to access faster data speeds.
Nothing is more important to a mobile device than battery life. Obviously, without electricity the iPhone is nothing but a brick. There are many battery saving tips that can help, but none of these is a comprehensive solution. BattSaver for iOS 7 provides highly customizable, one-stop radio management tools to extend battery power.
Users can toggle any number of specific options to control when and where radio components are turned on or deactivated to save juice. While the number of toggles can be overwhelming, there are battery saving Strategy presets such as iMessage friendly, Normal, Aggressive, and Ultimate. Each level will take more aggressive steps to disable cellular and Wi-Fi radios depending on circumstances.
If your iPhone 5s needs charging all the time, it turns out you're not alone. A relatively small number of users have reported that their brand new iPhone 5s battery drains abnormally fast. As it turns out, some iPhone 5s batteries are not performing as they should due to a manufacturing issue, and Apple is moving to correct the problem.
Apple did not specify exactly why the larger capacity 1570 mAh power pack was experiencing the problem in some units, however they are contacting affected customers about the issue. Of course, if you suspect that battery life on your iPhone 5s is substandard, the device is covered by a one year AppleCare warranty. Apple can test the device to confirm there's a problem before issuing a replacement or taking corrective action.
The best way to save battery life while using iOS 7 is by turning off everything you don't use. For example, the parallax effect may be neat, but what good is the illusion of 3D when your phone is dead? Or do you really need your phone to automatically update all your apps? Here are a few iOS 7 features you may want to disable or limit so you can get more use out of your battery.
Turn Off Parallax
You can turn off the parallax effect by navigating to Settings > General > Accessibility > Reduce Motion > OFF.
Turn Off Auto Downloads
You can go back to manually updating your apps by navigating to Settings > iTunes & App Store and scrolling down to Automatic Downloads.
If your iPhone 5 battery is acting up, it might be covered under warranty. For those who prefer to go it alone, iFixit covers the steps on how to replace the battery yourself.

The new iOS and Android app Carat promises users better battery life by delivering tips on how to conserve energy. According to TechCrunch, the app was designed by a " top-notch" team of "M.S. and Ph.D scientists from the UC Berkeley electrical engineering and computer science department’s Algorithms, Machines, and People Laboratory (AMP Lab)."
The free app uses gathered information from your device to decide what apps are hogging your iPhone's battery power. To do this the app has to take "measurements" from your device. This means you will need to allow it access for it to work. It also takes a few days to collect data before it can start sending you battery saving tips. So don't expect instant results.
