Being an iPhone user myself, I use my phone a lot for making calls, texting, web browsing, checking emails, and some casual gaming. With only around 1,440mAh of non-removable battery powering the device, I can’t ignore that slight disappointment of charging my iPhone twice just to survive the whole day. So I searched for what causes the iPhone’s fast battery drain and fixed them immediately.

#1 Location Services

One main cause of fast battery drain is the constant use of the Location Services feature of the iPhone. Location services enable certain iPhone apps like Facebook, Twitter, Instagram, Google Maps, Weather, etc to track down your current location by accessing the iPhone’s built-in GPS. The use of GPS requires a quite amount of power so it is advisable to turn on the Location Services feature only to selected apps which you actually use.

Just go to Settings > Privacy > Location Services then turn off unnecessary apps. The lesser apps listed, the better.

Also still under Location Services, scroll down to the bottom to find the ‘System Services‘ option. Click on it and try disabling the following:

  • Compass Calibration
  • Diagnostics & Usage
  • Genius for Apps
  • Location-Based iAds
  • Setting Time Zone

#2 Wifi and Bluetooth

Wifi and Bluetooth are also one of the top causes of fast battery drain. Just like GPS, both of these features also use up a huge amount of power to work properly. Therefore, it is important to turn off both Wifi and Bluetooth every after use to conserve more battery from your iPhone.

#3 Screen Brightness

Setting your screen to maximum brightness at all time? Then you’re in big trouble with your battery. The main touchscreen panel of the iPhone is also a major consumer of the device’s battery so if you’ve set the screen brightness manually, then put it in the mid-level brightness as much as possible.

More preferably, you can also use the built-in ‘Auto Brightness‘ feature of the iPhone which adjusts the screen brightness automatically based on your surrounding’s light source. To turn it ON, just go to Settings > Brightness & Wallpaper then turn ON the ‘Auto-Brightness’ option.

#4 Push Emails

Applications such as Mails frequently access the internet in background to get your emails even when you’re not actually using them. Though this feature is turned on by default, you have the option to lessen the frequency of fetching new data to save more battery.

Just go to Settings > Mail, Contacts, Calendars > Fetch New Data and turn OFF the ‘Push‘ option. Still on the same screen, scroll down a little bit and check ‘Hourly‘ under ‘Fetch’ selection to fetch your email on hourly intervals.


#5 Unclosed / Background Apps

The last thing to check to save iPhone battery is by closing all applications running in background. Generally in iOS, closing the application by pressing only the Home button doesn’t actually stops the application wherein some processes are still running in background, consuming some of your iPhone processing power and battery.

To avoid this kind of scenario, it is strongly advisable to always stop all background application still running by going to Application Switcher. To do that, just double click the iPhone’s Home button to show the App Switcher, long press a certain running app until it wiggles, then hit the minus sign to totally close the app. Only that simple. Like me, make it a habit to always close running background apps to save more battery life.

After identify all those causes and followed the mentioned tips above, I definitely noticed a significant improvement in my iPhone’s battery life. If you too got some additional iPhone battery saving tips, don’t by shy to share them by leaving a comment below.
