Question :

I recently got a new iPhone 6 and after about a week, for some reason it’s battery was empty with half a day, even on days when I rarely made any calls, played any games or made any photos.

Any idea what the problem could be ? (besides a problematic battery)

Answer :

In iOS9 you have the option to quickly check what apps have been using the most battery power lately. To do so :

• open the Settings.app –> Battery
• in the window that opens, wait for the rest of the page to load under “BATTERY USAGE” (this might take a few seconds)
• when the loading is complete, a list of apps is displayed together with the percentage of battery power they’ve used in het “Last 24 Hours” (or in the “Last 7 Days” if you click on the other tab-label)

If any odd apps show up in this list, make sure to always close these immediately after usage. To do so :

• double-click on the MENU(fingerscan)-button
• in the view that opens, select any app you need to close by putting your finger on it, the swipe up

…if that doesn’t help, there’s another service that might be draining your battery : Location Services. To shut down al unwanted and unneeded Location Services, do this :

• open the Settings.app –> Privacy –> Location Services
• in the window that opens, there’s no need to shut down Location Services right away, but you should go down the list of all apps that have would like to have your location info
• see if there is any app that is marked by an purple outlined arrow, and set the setting for this app to “Never”

…that’s it – enjoy !

…and if that doesn’t fix your battery problem, visit an AppleStore an let them check the quality of your iPhone’s battery

NOTE : the purple outlined arrow indicates an app that is constantly checking if you have arrived within it’s geofence, meaning it can start using your location since you have entered “it’s area”… this constant checking of availability costs a lot of power and is draining your battery…

more info on this is displayed at the bottom of the list of apps in the Location Services window
