For all the amazing features, improvements and performance boosts that iOS 7.1 update brought in, there are also some excruciating problems with the latest update. One major problem that stands out is battery drain.

Poor battery life is one of the complaints raised against Apple's latest update to iOS 7.1 as released the previous week. Not an easy bunch to impress, iPhone users have taken to Twitter complaining mainly about the battery drain problem. The Apple Community Forum message board is also full of concerns about iOS 7.1 update, the first stellar update to Apple's operating system for iPhones and iPads, according to Huffington Post.

Other than the battery drain problem, the update seems to cause poor "Bluetooth connectivity" and "spontaneous restarts."

Silver Lining

iPhone users have reported re-installing the software via iTunes helps resolve issues. But there is no clear resolution from Apple as yet, Yahoo Tech reported.

iOS 7.1 has already been downloaded onto 26 percentage of Apple devices since its release in the previous week, according to Mixpanel.

Should You Wait?

If you are one of those iOS users that have not yet upgraded to the latest iOS 7.1 version, you have a good reason to put off the updates in spite of having several improvements, fixes and refinements. Seemingly, the batteries in many different Apple devices are draining faster with iOS 7.1 installed than with any previous version.

Interesting Battery Test Results

Ars Technica conducted a couple of battery tests among various iOS version updates and here is what they have to say, "In the move from iOS 6.1 to iOS 7.0, we observed a statistically significant drop in battery life."

It noted iPhone 5 was the "biggest loser." Also, the move from iOS 7.0 to 7.1 did not make much of a difference. Its WiFi browsing test showed both small gains and losses, but most of these scores are different by two or three percent, which can be considered as within the margin of error.

Significantly, the first-generation iPad mini lost about 10 percent less battery life out of a single charge. Meanwhile, it's safe to say that unless something is wrong with your hardware, you'll get about the same battery life out of iOS 7.1 that you got from 7.0, Ars Technica claimed.

Also, battery life will vary based on the usage, hence it is subjective. Streaming content or playing games takes a toll in the battery more than the normal usage.
