When Apple released its iPhone 4S with iOS 5 software in October, one of the biggest shortcomings was battery drain.

iPhone and iPad users flocked to online Apple forums complaining about serious battery drainage, even when prime features, such as Siri, were not being used.

After admitting that the iOS 5 software had a battery bug, Apple quickly released an iOS 5.01 update, which claimed to fix the problem, but many iPhone and iPad customers were dissatisfied with the performance.

Apple hasn't introduced any more solutions to its battery problem in the past five months, but with the release of the new iPad last Wednesday, came the new iOS 5.1 software that again claims to boost battery life.

A glance at online Apple communities indicates that most people have noticed an improvement in battery life.

Finally Apple solves its battery issue with iOS 5.1, wrote one user on the Mac Forum. Huge improvement, wrote another.

But not everyone is happy with the performance.

One user even complained that their battery was draining even faster with the iOS 5.1 update, saying that the battery dropped 20 percent in just two hours. Another user said their battery had gone down by 60 percent overnight.

While battery life is entirely dependent on usage, most users across the board, who use the main features of their iPhone such as Siri and other location surfing apps, have made positive comments about their battery life on Twitter and other platforms.  People are now waiting to see how much battery drain Apple's all new powerful iPad will cause.

The new tablet comes with 10 hours of battery life, no different from its predecessor. But the new iPad is packed with new features. Here are some of the main specs:
