This is going to be my last post on the iPhone 4S since there is only one thing left to discuss and that is battery life. When I first got the phone I noticed the battery life was similar to the iPhone 4 but this weekend the battery life got so bad I actually went and purchased a car charger.
But I also found out why the phone started draining a lot more battery than my iPhone 4 ever did and that’s because I was using the Reminder App a lot because of Siri. When I tell Siri to remind me to pick up tea once I get to the supermarket, the phone starts checking my location at intervals to see if I’m at the supermarket or not so it could remind me to pick up tea once I am.
Once I turned location based reminders off I noticed the battery life went back to normal. It’s not hardware related since the Reminder App is also available on the iPhone 4 but Siri makes it more fun and easy to use. So to summarize things, the battery life is the same if you use the iPhone 4S like the iPhone 4, but once you start taking advantages of some of the iOS 5 features, battery life on both the iPhone 4 and 4S starts dropping considerably.
