Apple's upcoming tablets iPad 5 and iPad Mini 2 will have a better battery, according to Apple new patents.

The US Patent and Trademark Office Tuesday published 34 patents recently granted to Apple. They cover everything from the design of the iPad Mini to magnetometers used by the Maps app.

One of the most interesting revelations in the newly minted group of patents that could be applied to the upcoming tablets is one that deals with an iOS iTunes interface specifically designed for multitouch devices. The patent focuses on the Movie section of iTunes and states that the method described by the patent helps conserve power and achieves greater intervals between charges.

"Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated computing devices, such methods and interfaces conserve power and increase the time between battery charges," Patently Apple reported.

According to reports, iPad Mini 2 will feature a screen with a resolution of 2048 x 1536. This is almost four times the resolution of the present iPad Mini and is equal to the fourth generation iPad which was released along with the iPad Mini last year. AU Optronics has been rumoured to be making displays for the iPad Mini 2.

Other specs include a more powerful dual core A7 processor and a 7.9 inch screen. It will also feature a 10-hour battery life, a FaceTime HD camera, and an iSight camera with 1080 pixels HD video recording. Apple is also trying to reduce the thickness of the iPad Mini 2 by using the Sharp's IGZO (indium gallium zinc oxide) technology in its screens.

The iPad 5, on the other hand, is rumoured to have no bezels, and the whole form factor has been made sleeker. Horowitz believes this design indicates that Apple will be calling on Sharp's IGZO screen technology. Sharp, however, according to Horowitz, has been struggling, and its ability to deliver components on time will play a key role in the release of the next iPad.

Apple's CEO Tim Cook recently confirmed that no new Apple products will be released before fall 2013. However, the sudden disappearance of previous iPads tells consumers otherwise.

According to reports, iPad 5 is set for release in October; while the iPad Mini 2 will be released in Christmas. Apple may have decided to make a solo launch for both tablets due to the popularity of iPad Mini. The device was well-received by consumers in many parts of the world.

However, the Cupertino-based company remained tight-lipped on the rumours and on its plans for this year.
