As great as iOS 5 is, it sure seems to love sucking up battery, particularly on the iPhone 4S. I was getting substantially less battery life than I was on my old iPhone 4 running iOS 4.x, as were many others. A few tweaks made their rounds that were supposed to help with the battery issues, namely turning off some geo-location features and Siri options, but (at least for me) neither of these things resulted in very much.

Thankfully, Apple responded fairly quickly with iOS 5.0.1, which among other things is said to address the battery usage issues of iOS 5. I haven't been running it long enough to say for sure just how much better battery life is, but I'm not noticing my phone's battery taking a dive as soon as I take it off the charger anymore, so that's something.

Anyway, iOS 5.0.1 is available both as a full download through iTunes or by a ~50MB over the air update on your iOS device. Go to Settings, then General, then Software update and you'll be rocking out iOS 5.0.1 inside of about ten minutes or so.

    The battery life seems better but I can definitely say my performance is much better on my IPod Touch 4th gen and that's good enough for me.

      Same here - screen transitions are much smoother and it is much more responsive in general.

    I guess now that 5.0.1 is public, I can say that unfortunately my 4S battery life is still horrendous. A few people are looking into the cause, and it will be patched soon if Apple doesn't fix it by then.

      I had the same issue with my iPhone 4S 64GB.
      I turned off all location services-rebooted-turned on all locations services
      Battery life is back to normal, have not yet updated to 5.0.1.

    Don't worry mates, the new update "Improves voice recognition for Australian users using dictation." So throw another shrimp on the barby and download it now. Crikey!

    You might want to wait on the update since a lot of people are complaining about it:

    Update good for me on 3GS and iPad 1 - multitouch gestures on iPad 1 being the best feature (has to be enabled in General Settings)

    As a follow up, I disabled Location Services completely, rebooted, and my battery still dropped too fast. So I turned on LS again, except for:
    - Diagnostics & Usage
    - Location-based iAds

    And I turned off Siri. Battery is holding well, drop of 4% in 1 hour.
    I'll report back in a few hours, until then try it yourselves, but don't consider it conclusive.

      I've located a crash in the aps daemon, which handles iTunes WiFi Sync.
      Try turning that off, and reply here with your results please.

    Love the new iOS updating system, no longer do I need to download the whole operating system for a few tweaks.

    Looks like the Battery Drain might be coming from AirTraffic... it's having some kind of problem, which is keeping the radio open/on.

    I have an iPhone 4. My battery life was worse with iOS 5. It has improved with the update. After 3 hours this morning my battery is over 90% (with one infinity blade match in the middle and checking some other stuff on the iPhone)
