Q: iPhone 4S Poor Battery Performance SOLVED!!

iPhone 4S Poor Battery Performance SOLVED!!

 

I found the issue with the iPhone 4S battery performance.

 

I bought 2 iPhone 4S models on the first day. One for my wife and one for me. The strange thing was that mine would kill the battery in 4-6 hours and ran VERY WARM to the touch. My wife's phone worked great. It was cold to the touch. She would forget to charge it at night... and the battery performance was great... even better than our prior 3GS models.

 

What was the difference? I have my phone connected to Exchange for my corporate email. But exchange is not exactly the problem. The issue is in Notification Center. For some reason, I had hundreds of calendar reminders that kept refreshing on notification center. Furthermore, the reminders would flicker between the time remaining and the start time for the event at such a fast rate that it could not be read... (clearly a bug)

 

What is the solution? Go to Settings>Notifications>Calendar and disable Notification Center. You can still have the "alert style" set to Banners, or Alerts and you will still receive notices about your events, but it will not BUILD a summary in the Notification Center drop down screen. This is where the BUG exists. [Oddly, this does not affect my iPad 2, but is an issue for iOS 5 on the iPhone (different builds, maybe?)]

 

So, it appears that Notification Center has an endless loop in collecting the calendar events from Exchange and this is burning up our 4S batteries. Once you stop the madness from Notification Center, your iPhone 4S will perform as advertised.

 

Enjoy!

    I'm trying this immediately as I see the same crazy flickering with events.  Thanks for the tip.  Hopefully this helps.

    On another thread, others are seeing good progress with this fix... the issue is tied to Notification Center...

    This seems to have solved my problem with the battery life as well! Thanks

    I've had notification center off since I first got the phone, and still have terrible battery life. There is obviously something wrong with IOS5, but the way the phone will sometimes randomly overheat while charging makes me think there is a hardware fault as well.

    Wonder if it will still drain with airplane mode on?  I think I'm going to try this tomorrow.

    I do not think this is the issue, as I do not have an Exchange email account set up on my phone, but I still have battery issues.

    Well, in Airplane Mode, you no longer have an iPhone, you have an iPod
