The reports of the battery issues on the new iPhone 4S has been looming in the market for the past few weeks and a number of speculations has been aroused about why the battery is being drained at that speed?

Since the iPhone 4S went on sale last month, many have been reporting extremely poor battery life from their new handsets. The reports spread to iPhone 4 and iPhone 3GS owners, too, as they began to install iOS 5 en-masse. The issue manifests itself with iPhones struggling to last the day on a single charge, with at least one member of the Redmond Pie staff finding it hard to get an iPhone 4S through until lunchtime on occasion.

Now, ZDNet’s Adrian Kingsley-Hughes has come up with a startling observation, with a little help from a developer friend of his. His observation? Apparently, and I do hope you’re sat down for this, the battery issues are not, repeat not, hardware related.

Kingsley-Hughes comes up with the rather blindingly obvious observation after his guinea pig of a developer noticed that one of his new iPhone 4S handsets was suffering a severe loss of battery power, but one was not. He then decided to take matters into his own hands to see whether the problem could be ‘moved’ to the other handset by backing both iPhones up, and then restoring them using each other’s backup. Crafty indeed.

Shock-horror, the issue followed the backup to the previously OK iPhone, which anyone with more than a passing interest in these things could possibly have deduced by, oh, reading the umpteen posts, news articles and forum writings that suggest the issue is present on existing iPhone 4 and 3GS handsets. Did those develop hardware faults at the same time iOS 5 was installed? No, probably not.

Following this, inclusive of Apple took appropriate measures to find out why the battery is being drained and so far they have come up with around ten bugs or more, giving a nearly 100 percent affirmation that Apple iOS 5 has to be rectified for battery draining, and soon Apple is expected to release a fix to it. Meanwhile they have temporarily have released iOS 5.0.1, which gets the iPhones to last a bit longer than usual.

Until Apple comes with something substantial, keep following us to keep yourself hot on this issue!
