Apple is reportedly working to improve chip-level interference shielding in its phones, which could lead to bigger batteries.

According to 9 to 5 Mac, Korean news outlet ET News claimed that Apple is planning to introduce chip-level shielding that will prevent interference from a wide range of wireless signals. In the past, the company had introduced shielding for the circuit board as a whole. Individual chip shielding is said to offer many benefits including reducing size and allowing for bigger batteries.

"As clock signals of digital chips have increased and as diverse functions such as 3D-touch and others have recently added, reduction of electromagnetic waves have emerged as major topic of this industry," an industry representatives reportedly said according to Mac Rumors.

The speculation is being attributed to StatsChipPac and Amkor, two companies which are said to be working on shielding features in the iPhone 7. It was not known immediately if chip-level shielding is being introduced in the phones Apple is set to launch this year.

Among rumors in the recent past that have gathered steam include removal of headphone jack. Apple is reportedly planning to restrict wired-earphone connectivity to Lightning. A second speaker for improved sound output is set to be included. However, advanced digital noise-enhancement for earphones that were speculated earlier, may not be available until next year.
