  • Apple's Recent iOS 7.1.1 Update Reportedly Found to Seriously Improve Battery Life


    Only two days ago, Apple released the iOS 7.1.1 update for iPhone, iPod touch, and iPad to the public both over the air, and as an update through iTunes. The software update included a number of bug fixes, including a major one for iPhone 5s users that is supposed to improve the accuracy and stability of Apple's Touch ID fingerprint-scanning technology so that it would stop becoming inaccurate over time.

    On the other hand, iOS 7.1.1 also reportedly brings very positive battery life gains to the mobile operating system, as ZDNet's Adrian Kingsley-Hughes claims:

    However, following iOS 7.1, I started seeing the battery drop to around 48 percent per six hours of use, which was a significant and very noticeable level of degradation.

    ...

    Then came iOS 7.1.1. Following this update I've noticed that things have improved dramatically, and now battery life is only falling to around 76 percent per six hours of average use, which is better than what I was getting pre iOS 7.0.
    Kingsley-Hughes mentions that he has been keeping records of battery usage on his iPhone 5 with each major update from pre-iOS 7 until now, and notes that iOS 7.1.1 includes some of the largest battery gains to date. Other sources seem to agree that the update improves battery life on other devices as well, including iPads.

    Notably, iOS 7.1.1 cannot be jailbroken at this point in time, so we haven't gotten around to updating our devices, and if you're jailbroken, we advise you to stay away as well. But, if you're one of the unlucky few to end up with a device running iOS 7.1 or later, you might have a good reason to upgrade to, or use, Apple's iOS 7.1.1 release.

    If you have already, have you noticed any significant gains in battery life?

      That's strange, because I've dropped to 40% after five hours of use on my iPhone 5s. I'm not sure if it's an improvement from 7.1. It seems to be pretty consistent with all versions on my phone. Am I really supposed to be getting to 76% after six hours??

      Yes it is a massive improvement
      I was using 70% a day
      In the last 2 days I've used 12%
      I'm one of the people that's been working with apple on fixing it
      I made apple replace 3 phones
      I could have had 6 phones but I sad enough apple sort it out
      Now they have
      The fingerprint scanning was one of the areas of batt burning

      Anecdotes about battery life have been around for years. Until a proper test is done they're meaningless.

      What are the chances of us getting a JB for 7.1.1? This would be a good upgrade but I don't want to lose my current JB..

      I was thinking about doing that, but Apple voids jailbroken device's warranties. I don't want to remove my jailbreak just for them to (possibly) tell me "Just update to iOS 7.1.1, you'll be fine."

      I read that article. I bet the guy forgot to run Facebook that day and thus the improved battery life!

      I wouldn't risk it. But they technically don't void it unless you can visibly tell it is jailbroken. So if you were to use a tweak with your PC to hide cydia after removing all your tweaks you would be fine. But wouldn't apple just give you a new phone because they are a*******?

      First thing they would say is "try upgrading to 7.1.1" once they see it's still on 7.0.4, so you'd be screwed either way.

      You must be insane to even consider losing your jailbreak. Apple could release 7.1.2 allowing you to control your iPhone with your mind and with holographic features and with a battery that lasts a year on 1 charge and I still wouldn't even consider losing a jealbreak for it. The only version I would lose a jailbreak for is another jailbreakable version

      You should try SmartClose tweak by Ryan Petrich. You assign an action via the activator (I have configured it to run when I press the Power/Lock switch)... It puts all the apps in the app switcher into a deep freeze state. By default, the background apps keep pulling data and draining battery life for 5-10 minutes even after you lock the device. This tweak might help you extend the battery by an hour or 2.

      I like playing graphic intensive games for 2 hours daily... and still my 4S lasts me around 7 hours.. the rest of the time is basic messaging, web browsing and video streaming... and its 2 years old, never RMA'd for any problems. Before the smart close tweak, the battery drain was very noticeable the moment i "upgraded" to iOS 7.0.6.. and I came across this tweak. Have also switched off 'Background App Refresh' in the settings app.

      Hopefully this might improve your battery life by a tad bit... not a lot though.

      Hope there is a 7.1.1 JB before Apple fucks up again with iOS 8... I can't remember when was the last time Apple released a stable iOS... pathetic... just milking their loyal customers and forcing updates on people who still want to stick to iOS6
