Push Notifications were introduced to iPhone 3G and continue to become more and more popular with developers as a way to make their apps more interactive but it comes at a price, battery life.
This appears as a part of my iPhone Battery Saving Tips & Tricks series.
Push Notifications in iPhone OS 3 and still in iOS4 continues to drain the battery at an alarming rate in some cases and more often than not are just not necessary.
There are two types of Push Notifications on iPhone, one for apps and one for mail.
I’d recommend tweaking both for better battery life but only the apps one is covered here.
This has been carried out and tested on an iPhone 3GS running iOS4.
