So far mine seems to be a little bit better.


Its still not as good as it should be. My iPhone 4 is on 10 hours of standby at 98% (shows 10 min usage, though i havent touched it till checking)

My iPhone 5 is at 70 after 10 hours of standby and it says 53 minutes of usage, even though I touched it twice to check usage for a few seconds.


before update my iP5 would be dead by now.

Well, it won't magically make the 4 or 4S battery larger and that's the problem. This is a hardware issue, folks -- iOS 6 and iOS 5 both demand a lot more from the hardware than iOS 4 and previous versions did and the batteries in both phones were fine by 2010 standards, tiny by 2012 standards. How can you get around it? Learn to stay near a charger.


The "battery drain" issue popped up in iOS 5 and it's here to stay. I wonder if battery life is vastly improved on the iPhone 5 (which also uses a battery that seems small on paper).

Updated 6.0 with 6.01 today. I thought my problem with battery drain was improved but once I set my email to Push or Fetch, the battery level dropped very fast. When iOS6 was installed on my iPhone 4, I had a big problem with the battery drain. Apple checked my battery and even loaded a bit of software on my phone, which ran for several days; I then uploaded the file to Apple. I use my phone for extensively for business and receive numerous emails and communications during the day. However, in order to use my phone, I have to set things up to manual update and pretty much shut everything to off. Once I do this, the battery runs like new. The problem with this scenario is that my "used to be" smart phone is now a dumbed-down phone that requires me to manually perform tasks that used to run in the background. I was hoping that this new update would correct the problem, but it did not happen. Same old problem with the battery. Extremely frustrating.

Same here. updated to 6.0.1.

Battery continues to drain as fast as it did with 6.0 and now it seems my iphone is getting even hotter than before even while in standby.


I've been an Apple user for abount 15 years and now it's the first time i'm seriously (and sadly) considering switching to other manifacturer. It just does not work! it's unacceptable. very frustrated with this.
