Can the iPhone 5 avoid the 4S battery life problem?

Siri? iCloud? Bug? How can the next iPhone avoid the much-publicized battery life problem reportedly (and still) plaguing the iPhone 4S.

The iPhone 5 is still considered as a big all caps RUMOR, but apparently, Apple will release a new iPhone next year and it will use the iPhone 5 moniker.

Rumors this week talked about the iPhone 5 release date and features. From dual-core to quad-core CPU to larger screen and new design, of course, it is still the same old cycle of rumors circulating on the internet claiming that Apple’s iPhone 5 will be the biggest and the most aggressive iPhone yet.

But there’s a catch, majority of rumors don’t talk about the battery life. Yes, quad-core CPU will likely drain the battery juice of a phone faster compared to a dual-core, and it is not a myth. Larger screen? Yes, more pixels per inch and larger display will drain the battery faster compared to smaller screen.
Apparently, Apple’s iPhone 4S received (and still receiving) bad publicity due to the reported bug draining the battery juice of the new dual-core iPhone. According to Apple, the problem is due to a “bug” and only affecting a small number of iPhone 4S users, but based on a discussion in Apple’s own website, many are still complaining.
One iPhone user said he is in love with the iPhone 4S, but doesn’t like the quick battery drain, “I received my phone last weekend and experienced 5 to 8% battery drain per hour. The apple store wiped my phone and disabled some apps – however that did not resolve the problem. The rep blamed having an exchange email account as part of the problem. Don’t get me wrong – I love the phone – however I hate having to keep the phone near a charger throughout the day.”
Another discussion contributor added that the problem may be related to the iOS 5 and not the hardware or dual-core CPU. “Yea, it’s a problem with the iOS 5! My iPhone 4 has this problem after updating to iOS 5.”
Reports say Apple is set to end the problem with a new software update, but what if the problem is not software related?
If Apple’s iPhone 5 will include LTE or quad-core CPU, it must also include a larger battery, or better, they should stick with dual-core CPU and HSPA+ next year to avoid the same battery life problem.
Another reason why the iPhone 5 should use dual-core CPU or larger battery is due to the iCloud which is reportedly adding the juice-draining problem especially the “iCloud Backup” feature.
