I've aggregated the best steps I can find to increase your iPhone 5's battery life. This applies to iPhone 5 or 5S on iOS 7 and above.
In This Guide, I Tell You How I Personally Get Great Battery Life on My iPhone 5. There Are Many Factors That Cause Horrible Battery Life on The iPhone 5 but I’ll focus on some of the tools that I use to ensure That I get a full days use out of my iPhone.
Turn off Push Email
Long ago, I turned push for email off. Not only did I hate the fact that my phone was constantly buzzing or ringing but I also realized that my battery life took a hit because my phone was constantly working to pull email for me. I get a large volume of email per day and it simply started eating at my battery.
With push turned off, I now check email at my own leisure without the annoyances. Better yet, my battery life doesn’t take the hit that it took before I shut it down.
While I turned push completely off, iPhone 5 users can simply set the phone to check at larger intervals. Checking every 15 to 30 minutes is much better than checking every minute.
Checking email less often will not only be good for your sanity but it will also be good for your iPhone 5′s battery.
Turn Down Screen Brightness
Another setting I have permanently changed is the screen brightness. Instead of using Apple’s default or Turning it all the way up, I have moved the slider all the way down to the lowest setting. Even on the Lowest setting I have an easy time seeing things on the home screen and watching content that I pull up During down time.
So why do I do this? Simple. The iPhone 5′s display is one of the biggest drains on battery life and by Keeping the brightness low, it minimizes the drain.
There are times when I need a brighter screen and all I do is pull up iOS 7′s Control Center from the bottom of the screen, adjust the brightness and then put it back down once I am done. Users who don’t trust themselves to change can set the brightness to Auto but even on Auto, my iPhone 5 experienced some problems.
Simply get into a habit of adjusting it when you need to adjust it and you’ll be much better off.
Don’t Kill Apps That Are Multi-Tasking
Yup, that’s right. Don’t kill these apps. It turns out that the work your phone does to reload these apps into the phone’s RAM is more draining on the battery than keeping them in the RAM if they are already there. Your phone is already doing a good job of managing what is actually running. Seeing these apps here doesn’t actually mean they are running.
Turn Off Automatic Time-Zones
In the ‘General – Date & Time’ section of settings, turn off the ‘Set Automatically’ setting. This just means that when you change timezones you will have to go in here and set the new timezone manually.
Turn Off AirDrop
When you’re not using AirDrop, it’s best to keep it off. Just swipe up to bring up the Control Center and click on AirDrop and click ‘Off’.
Turn on Reduce Motion
Ok, this will take away some of the pretty animations in iOS 7, but you can always turn it back off if you want the animations. Go to the ‘General – Accessibility’ section of Settings and turn Reduce Motion to ‘On’
Set Auto-Brightness to On
- Go to the ‘Wallpapers & Brightness’ section in Settings
- Go to a dark room and set the brightness all the way down.
- Turn Auto-Brightness On, then Off, then On again. This will recalibrate it.
Your phone should do a good job of adjusting the brightness so that it isn’t unnecessarily bright when it Doesn’t need to be. The screen is one of the most power intensive aspects of your phone.
Reset All Settings
It’s possible that over the past few months, or even year, you’ve toggled on some settings that are contributing to poor battery life. Fortunately, Apple makes it extremely easy to reset iOS settings without erasing your data, photos, apps, or contacts. Everything but the settings will remain the same.
By resetting all settings, it will restore the iPhones settings to the default. From there, you’ll be able to easily pick and choose what you want enabled and what you want disabled.
To do this, go to Settings -> General -> Reset -> Reset All Settings -> Enter your PIN to complete the process. This is a process that will take several minutes but it’s one that could dislodge bugs and help to better preserve battery life.
