but if you think you cant give up on your facebook app !!
Here are few tips to boost your I phone battery life
LOW POWER MODE
A new mode in iOS 9, Low Power Mode, reduces overall power requirements and makes your battery last longer. Apple claims the new mode will allow you to gain three extra hours of battery life from your iPhone.
In iOS 9 and 8 you can see exactly which apps are the biggest battery drainers.
Go to Settings > General > Battery and scroll down to see which of your apps were the biggest battery guzzlers in the past 24 hours, or last 7 days.
If you still need a cellular connection but can DO without Wi-Fi,
you can disable Wi-Fi by swiping up to reveal Control Centre and tapping the Wi-Fi icon to turn it off (if it’s off the Wi-Fi icon will be black).
This will stop your phone from searching around for Wi-Fi networks it could join.
Tone down visual effects
One of the coolest features introduced in iOS 7 is called Background Motion.
It’s subtle, but if you move your iPhone and watch the app icons and background image, you’ll see them move slightly independently of each other, as if they’re on different planes. This is called a parallax effect. It’s really cool, but it also drains battery. You may want to leave it on to enjoy the effect, but if not, turn it off by tapping on the reduce motion .
