“iPhone and iPad users running the latest software version, iOS 7.1, is considerably draining battery life, according to some users.
The iterative software update, released on Monday, boasts a number of new features, including accessibility tweaks and user interface design changes, along with a number of security fixes.
According to the latest research, iOS 7.1 is already on 21 percent of all iPhones and iPads — making it one of the fastest uptake of a new mobile operating system version in recent history.
But despite internal extensive testing and five iterative beta versions issued to Apple developers, the battery life on some devices appears to be dropping far more than it did on iOS 7.
Ars Technica tested the battery life across a number of devices, including the iPhone 5s, and iPad models, and discovered that battery life was in nearly all cases slightly lower in iOS 7.1 than the latest version of its predecessor, iOS 7.0.6, which landed in mid-February with an SSL connection bug fix.
But that doesn't account for some of the complaints by some Apple customers.
From Apple's own discussion forums, one user said, "overnight charge decreased from 100 percent to 30 percent." Meanwhile, others have seen similar drops in battery life. Another user said: "My battery drains to 50 percent within an hour or so after intense use on the lowest level of brightness, and I seem to lose about 5-7 percent when on standby for 5 hours or so."
Others said they had 24 hours of moderate to heavy use, but now get half that. Some saw even more dramatic drops in their battery life. One forum member said, "I just charged the battery to 60 percent an hour ago... but now is 36 percent."
If, in general, your battery life is consistently short and you're basically just watching the indicator drain down before your eyes, here are some things to try, in order of how easy they are to do.
·Check your cell signal. If you're in an area of weak signal, or at the edge of LTE or 3G support, your iPhone's radio could be screaming away on full power just trying to stay on the network, or switching between connection types, and wasting a lot of power. Good LTE signal is more power efficient than good 3G signal (because the radio can fire up, do its job, and power down much, much quicker), but bad LTE signal is just as bad as bad 3G, which is terrible. If you're at the edge of LTE, switch to 3G. If you're almost off the grid, turn off the radio unless and until you need it. Then get back to world as fast as you can!
·Reset your network settings. If you're getting a bad cell signal or your carrier is working on towers causing your signal to jump, resetting your network settings can sometimes help alleviate issues. Try this before anything else if you're noticing only 1-2 bars of signal in certain areas you frequent.
·Quit power hungry apps. Double-click the Home Button to activate the multitasking car view and quit, hold your finger down on power-hungry apps, and then fling them off the screen to close them. This is key for apps like VoIP (like Skype), streaming audio (like Pandora), or navigation (like TomTom). Anything running all the time will drain battery. That's how batteries work. Some apps can also fail to sleep properly when not in use. If quitting Facebook stops your battery drain, quit Facebook. After some experimentation you'll find occasional and chronic offenders alike.
·Restart/reset your device. If you haven't rebooted in a while, give it a try. There could be a rogue process or something else doing what it shouldn't be doing, and a restart can often fix that.
·Power cycle. About once a month, and certainly if you think you're having problems, you should completely drain your iPhone, iPod touch, or iPad's battery -- drain it until it shuts down on its own -- and then charge it back up to full. That re-calibrates the battery indicator and you'll get a more realistic idea of what your levels are. can solve by either swapping it for another device or otherwise figuring out a fix.
·Go to the Apple Store. Sometimes you do get a lemon, or your iPhone or iPad develops a real problem that only Apple can fix — by servicing or replacing your device.
