We all face this problem from time to time: Your iPhone dies while you were using the Maps application because you’re in a place you know nothing about, or you have to make this important phone call but your iPhone waves goodbye unexpectedly.
There are some tips you may consider to preserve your iPhone battery in case of emergencies.
1- Your iPhone is not a Bulb
Why do you always use maximum brightness settings for your iPhone?
It’s not necessary at all, you may want to turn on automatic-brightness to save your battery life.
2- Don’t forget to close the applications when you no longer use them
This significantly affects your battery life. Imagine 10 applications running on the background of your iPhone, not cool right? You may want to close Facebook after reading your newsfeed. Double click on your home button and a list of running application will appear, close the ones you don’t need.
3- Don’t run LTE and Wi-Fi at the same time
Why would you need both? Turning both 4G and Wi-Fi will drain your iPhone battery. If you’re running on your 4G plan, then you don’t need wireless internet, and vice versa.
4- Turn Bluetooth off
I’m one of the guys who never used Bluetooth on his iPhone. You may find it useful, of course, but I don’t think you’ll need all the time. Always check that your bluetooth is turned of, because it negatively affects your iPhone battery.
5- Prevent Background App Refresh
This feature looks at the apps you use most often, the time of day that you use them, and then automatically updates them for you so that the next time you open the app, the latest information is waiting for you. For instance, if you always check Facebook at 7:30 am, iOS 7 learns that and automatically updates your social apps before 7:30 am. Needless to say, this useful feature drains battery. To turn it off:
Settings -> General -> Background App Refresh -> Either disable the feature entirely or for specific apps
6- Don’t forget to lock your screen when you’re not using your iPhone
Leaving your screen turned on will drain your battery. Always make sure your iPhone screen is locked when it’s inside your pocket.
7- Coolest thing ever: A portable charger
If you need your iPhone to be up and running the whole day, then a portable power source is your best option. Check Amazon for a list of portable chargers based on your needs and budget.
