Apple iOS 15.4 official version is too power hungry? Some users said that the battery life plummeted to half a day

Hello, welcome to the Elsevier Assistant, which is used by 200 million iPhone users.

Ai Xiaosi has prepared a quick list of today's news for you, please check it out:

One: iPhone 14 and iPhone 14 Max continue to use A15 chips?

Recently, it has been reported that the design and configuration of the iPhone 14 model and the iPhone 14 Pro model are significantly different.

Specifically, the iPhone 14 and iPhone 14 Max will continue to be powered by the A15 Bionic processor, while the iPhone 14 Pro and iPhone 14 Pro Max models will be equipped with the yet-to-be-released A16 Bionic SoC.

Now, analyst Ming-Chi Kuo has revealed more details about the use of different chips. He said the chip difference between the iPhone's non-Pro and Pro models could be a marketing or financially based decision.

Kuo claimed that the supply of TSMC chips was not a problem. This has led to speculation that Apple is trying to establish a bigger distinction between the iPhone's non-Pro and Pro models, or that it is trying to keep costs low by using older-generation chips in non-Pro models.

It has also been reported that while all models of the iPhone 14 series will contain 6GB of RAM, non-Pro models will be equipped with LPDDR4X RAM. On the other hand, the Pro model will have LPDDR5 RAM, making a difference.

Two: Studio Display runs iOS 15.4 full version!

Daring Fireball's John Gruber emphasized that Apple's Studio Display runs the full version of iOS 15.4.

Under "Graphics/Display" in the system information, you can see studio Display's software, showing that it is running "Version 15.4 (Build 19E241)". This is exactly the same as the build numbers for iOS 15.4 and iPadOS 15.4, indicating that Studio Display is running the full version of iOS.

The Studio Display includes the A13 Bionic chip, identical to the iPhone 11 lineup, 2020 iPhone SE, and ninth-generation iPad to support its 12-megapixel ultra-wide front camera with character centering and a six-speaker sound system with spatial audio.

While the presence of the A13 chip suggests that the display is likely to run a variant of existing Apple software, just as the HomePod and HomePod mini run a version of tvOS, the exact software content of the device is unclear so far.

With the confirmation that Studio Display is running iOS, an update that Apple is planning to improve the quality of its webcam may come as part of the iOS update.

Three: Shock! Former Apple employees were charged with recovering deductions and fraud, costing the company tens of millions of dollars

According to the IRS and federal prosecutors, a former Apple employee is suspected of receiving kickbacks, fraud and embezzlement charges, which cost Apple tens of millions of dollars.

The former employee, Dhirendra Prasad, is 52 years old and worked at Apple from 2008 to 2018, spending most of his time as a buyer in Apple's global service supply chain. Taking advantage of his position in cooperation with suppliers, Prasad allegedly "participated in several different scams to deceive his own employers.".

Prasad's offenses include "accepting kickbacks, stealing parts, and causing Apple to pay for products and services it never received," as well as other allegations of fraud, money laundering and tax evasion, each punishable by up to 5 to 20 years in prison. These activities allegedly cost Apple more than $10 million in total.

The case has yet to be tried, and Prasad will appear for the first time next Thursday in the U.S. District Court in San Jose. Law enforcement agencies have obtained court approval to confiscate Prasad's $5 million worth of cash and property with the aim of preserving the assets as proceeds of crime.

Prasad wasn't the only one linked to the scam, two other men in California were involved in the case, who owned the company that sold products to Apple and conspired with Prasad to commit fraud and money laundering. Both have been charged in different cases and both have "confessed their crimes".

Four: Apple iOS 15.4 official version is too power-hungry? iPhone 13 Pro Max users say battery life has dropped to half a day

According to GSMArena, earlier this week, Apple began to launch the official version of iOS 15.4, along with iPadOS 15.4, watchOS 8.5, macOS Monterey 12.3, tvOS 15.4 and HomePod software 15.4 updates.

Its biggest highlight feature is wearing a mask and using Face ID to unlock your phone. However, the new Face ID feature is only available for the iPhone 13 and iPhone 12 series.

In addition to some new features and bug fixes in iOS 15.4, more and more people are reporting poor battery life after OTA. Some netizens said that Apple's iPhone 13 Pro Max mobile phone can only maintain a half-day battery life. Older iPhone 11 phones have an 80% reduction in battery power and a 2-hour screen on time in 24 hours.

Of course, this problem is far from a common phenomenon, and some temporary battery problems after the update are sometimes expected. Some users speculate that Apple has started using proMotion refresh rates up to 120Hz more frequently. That sounds plausible, but that might not be the whole explanation, as only the iPhone 13 Pro and Pro Max have ProMotion refresh rates, and these aren't the only models affected.

It is hoped that these issues will be resolved as soon as possible.

The iOS 15.4 release update also includes more than 100 new emojis from Emoji 14.0, new voice options for Siri and the ability to deliver time and date information offline, support for EU digital COVID certificates in Apple Wallet's vaccine cards, Safari web translation improvements that support Italian and Chinese, improvements to the podcast app, and more.
