Apple's newest operating system, iOS 7.1, was released two weeks ago, and some iPhone users find that newer doesn't always mean better.
"When I use the Internet, Facebook or apps, the battery level drops dramatically quickly," said Kevin Kibbe, of Enfield.
Kibbe has had his iPhone 4S for about a year and a half. He admitted his device never had a great battery life, but said it's gotten worse since installing the upgrade.
"[The battery] will make a drastic jump from 34 percent, to 1 percent, to off."
That's something the NBC Connecticut Troubleshooters witnessed, too. We asked Kibbe to use the Internet on his phone during our interview; his battery power fell by about 1 percent every minute.
Kibbe said his phone's battery is so weak, he constantly has to charge it.
"I always have to carry some sort of power source with me."
Kibbe isn't alone. Since Apple released 7.1, its message boards have been lighting up.
One user claimed, "Immediately after install of 7.1, my battery... which lasted almost the entire day, suddenly last [sic] a couple of hours."
The Troubleshooters called and e-mailed Apple for a comment but haven't heard back.
There are a few things you can try if you're having battery issues.
One: reboot your phone. If that doesn't work, hit "settings," "general," then "reset" and "reset all settings." That will bring your phone back to the way it was when you took it out of the box; you may then have to go back and change your settings again.
"If all else fails, take a backup of the phone and then through iTunes, do a restore of the phone. Basically, wipe it out and then reload your data on top of it. That's usually what fixes it for most people," said Lon Seidman, tech expert and CTNewsJunkie.com writer.
Seidman recommends that iPhone users visit the Apple store if they experience major problems.
Despite complaints from some iPhone users, Seidman said 7.1 performs well on many phones. The program has fixed previous bugs and is helping some phones work faster. The upgrade also boasts different features and designs.
But those fixes aren't enough for Kevin Kibbe, who said he's tried everything to preserve his battery and nothing has worked. He can't get a new phone because he's not eligible for an upgrade. He's hoping Apple's next iOS patch fixes the problem.
"It can't get any worse, can it? There's only one way to find out," said Kibbe.
It's unclear when Apple will release the next iOS upgrade.
