Apple Inc. is recently faced with battery deficiency complaints among its users after a seemingly sudden shutdowns event on their iPhones 7, iPhone 6S and iPhone 5S. The news comes after the users upgrade to the latest OS 10.1.1 update, which the company claimed to be caused by a manufacturing flaw in September and October.

According to Inquistr, iPhone 7, 6S and 5S owners reported that their smartphones' Phone Apps have started freezing during usage. On the other hand, iPhone 6S owners experienced an abrupt change on their devices' battery levels after pointing sudden shutdowns, even if the battery level was still 30 to 40 percent.

Because of the battery fiasco experienced by iPhone 6S users, the Cupertino-based tech giant recalled a limited number of the handset in November, indicating that the event is not a safety issue and the battery will not be changed.

During the recall program, users are advised to visit an Apple retail store or an authorized service provider. Then, the company's resident experts will examine their iPhones beforehand to make sure it is eligible for the repair.

To address the issue at hand, the company has released a statement explaining the unexpected shutdowns encountered by limited users, GSMArena reported. The tech giant admitted that some of its handsets were prone to malfunctioning after upgrading to iOS 10.1.1, which were exposed to too much air during the manufacturing process.

The statements say: "We found that a small number of iPhone 6S devices made in September and October 2015 contained a battery component that was exposed to controlled ambient air longer than it should have been before being assembled into battery packs. As a result, these batteries degrade faster than a normal battery and cause unexpected shutdowns to occur. It's important to note, this is not a safety issue."

Earlier this year, its major rival in the smartphone market, Samsung, was compelled to recall its new Galaxy Note 7 phone after its battery exploding fiasco. To address the issue, Samsung instructed users to shut down their phones and in October issued a recall of all Galaxy Note7s, including replacements.

On the other hand, the Apple Inc. has launched its own solution for the battery issue through a free repair and replacement program for affected iPhone 6S units. Unfortunately, Apple has not released an official statement regarding the concerns of iPhone 7, 6S, and 5S users who complained about Phone Apps freezing.

Before closing the issue, Apple told that a software update to iOS 10 could possibly fix certain phones, which users could only hope to address this latest flaw.
