When it launched, the iPhone 4S had a serious problem: it had terrible battery life. Even moderate users were lucky to get through a work day without needing to recharge. Apple quickly released an iOS 5.0.1 upgrade to remedy this problem, but does it do the job?
In my experience, it certainly does. Before this update was released, I’d gotten in the habit of keeping my iPhone 4S plugging in all the time at work so I would have more than a 40% charge when it came time to leave. Now I can easily go a couple of days without needing to charge.
To give you some hard numbers, one of my tests was an 18.5 hour day during which I used the smartphone for 2.5 hours and left it on standby for 16 hours. By the end, I still had a 68% charge. In a multi-day test, the iPhone 4S was used for 8 hours but was on standby for 48 hours. The result: a 33% charge.
These are quite good numbers. Above average, considering getting through two full days of heavy usage and still having a decent amount of power left over is something many smartphones can’t provide.
Not a Simple Answer
You’d think everything was cut and dried at this point — Apple has solved the problem — but it’s a bit more complicated than that. See, whatever bug it is that’s causing the iPhone 4S (and other devices running iOS 5) to having battery problems doesn’t act consistently from one device to another.
Some people have never understood the furor, as their device has always performed fine. Consumer Reports is in this category, as it gave the iPhone 4S high marks in this area. Others have complained that the iOS 5.0.1 update actually made their battery life worse
Apple is reportedly working on iOS 5.0.2 that will help remedy this problem once and for all, for everyone. Only time will tell if this will lay the problem to rest.
