26 ways you're unknowingly draining your iPhone's battery

Always relying on cellular data

Some people think that turning Wi-Fi off will improve battery life. That’s a myth. Turning the wireless setting off can actually worsen battery life on your iPhone. The amount of Wi-Fi power taken to communicate with Wi-Fi base stations is minimal and way lesser than what using data will do to drain your battery in a jiffy.

Do this instead: Simple. Whenever possible, use internet Wi-Fi.  Under Settings, make sure Wi-Fi is switched on, and leech onto a Wi-Fi source as much as possible. 

Not using Airplane Mode enough

That little airplane icon is underused. Leaving your phone on Wi-Fi when you know you’re definitely not going to get any complimentary connectivity means your phone has to work harder to communicate, at the expense of your iPhone’s battery life.

Do this instead: At infamous dead zones with zero coverage or when you’re overseas, turn on Airplane Mode. You can get to it right from Control Centre by swiping up from wherever you are on your iPhone without having to weave your way around the workings of your iPhone. Otherwise, access it from Settings, then Airplane Mode.

Overbrightening your phone

We know the iPhone has a beautiful Retina-ed screen and it’s really tempting to blitz the brightness all the way up. But don’t, because that 4.7in display will sap your battery before you can even say “lighten up”. There are a few ways you can play around with the display to make it easy on your eyes and on your battery. 

Do this instead: Head to Settings, then Display & Brightness, and switch on Auto-Brightness. Your iPhone will figure out the best level of brightness that won’t put a strain on your eyes or your battery. Also, go for a static wallpaper instead of a dynamic one. A moving wallpaper might be fun and all, but it takes a toll on your battery. 

Lastly, don't just use Night Shift at night. You can manually turn the easy-on-the-eyes feature on for whenever you like, for however long you like. 

Keeping Parallax in play

While the parallax effect is a nice little touch that iOS 7 brought to your iPhone, running it actually keeps your phone’s motion sensors in play, which in turn takes a toll on your battery life.  

Do this instead: Switch off the parallax effect. It’s not that significant to bring about a drastic decline in your iPhone experience. Go to SettingsGeneralAccessibility, and lastly, Reduce Motion to turn it on.

Neglecting updates

Oh great, there’s a new update out, but I'll put it on hold because I need full use of my iPhone now. And then guess what, that update remains uninstalled. Lest you forget, updates contain bug fixes and the latest in software changes to make your iPhone work even more efficiently for you.

Do this instead: Make sure you get on that update as soon as possible instead of leaving it languishing in a corner of your iPhone. Go to SettingsGeneral then Software Update to get your iPhone up to speed. If you haven’t got the latest update installed, it’s not the iPhone, it’s you. Remember to update your apps too as their developers would always release the optimised versions with every major OS update.
