The latest iPhone 6s and 6s Plus have garnered amazing popularity worldwide and it has been reflected in the number of orders placed by customers on e-commerce sites and offline stores.

However, iPhone 6s seems to have one issue of battery life. If you compare the battery capacity of all the four iPhones, i.e. iPhone 6, iPhone 6 Plus, iPhone 6s and iPhone 6s Plus, you will notice a considerable difference between iPhone 6 (1810mAh Li-Po) and iPhone 6s (1715 mAh Li-Po); while there is no difference between battery capacity of iPhone 6 Plus (2915mAh Li-Po) and iPhone 6s Plus (2915mAh Li-Po).

This has created doubts in the minds of users, and many asked questions regarding how to check if iPhone 6s or iPhone 6s Plus has TSMC or Samsung A9 chip. So we found the solution in an app.

First, you need to download Battery Memory System Status Monitor, developed by Cactos App.

How to Check if Your iPhone 6s/6s Plus Has a TSMC or Samsung A9 Chip

Step #1. Open Battery Memory System Status Monitor on your iPhone 6s.

On the top menu, you can see four tabs: Summary, Processes, System, and Network.

Step #2. Tap on System tab.

On your iPhone 6s, you can see information like OS, Kernel, number of CPUs, model, name, Cache Line Size, L1 Cache Size, and other.

The model name is the key, which opens the secret. Check your iPhone 6s model name and you will find if your phone has TSMC or Samsung A9 chip.

If your iPhone 6s Plus is made with A9 chip by TSMC, the model name will be N66mAP

If the model name of your iPhone 6s Plus is N66AP, it has an A9 chip from Samsung

In case, the iPhone 6s has an N71mAP model name, it is manufactured by TSMC with A9 chip

If the model name of the iPhone 6s is N71AP, it is made with A9 chip by Samsung

You must have noticed that the alphabet “m” is common in the model names of iPhones with an A9 chip made by TSMC.

There is another app available to check whether your iPhone 6s has TSMC or Samsung A9 chip.

Download Lirum Device Info Lite – System Monitor, developed by Rogerio Hirooka.

Step #1. Launch the app on your iPhone 6s.

You will see three different options at the bottom menu.

Step #2. Tap on Home.

Here you will find the Model name of your iPhone 6s.

If your iPhone has a Samsung chip, you will find model names: N66AP or N71AP. And if the model name is N66mAP or N71mAP, the A9 chip is made of TSMC.

Check if Your iPhone 6s/6s Plus Has a TSMC or Samsung A9 Chip on Mac

You can also check the manufacturer of A9 chip from your Mac. First, download iMazing on your Mac.

Step #1. Open iMazing on your Mac.

Step #2. Now connect your iPhone 6s/6s Plus with your Mac.

Step #4. Scroll down and check the Hardware Model name.

If the A9 chip is made by Samsung, it will show the model name: N66AP or N71AP. And if the chip is made by TSMC, the model name appears N66mAP or N71mAP.

There is one more option for you to check the manufacturer of A9 chip on your iPhone 6s or 6s Plus. For this, you need to download CPUIentifier software on your iPhone. Before you go for this process, a word of caution: this method is not recommended by experts because CPUIdentifier doesn’t work on every iPhone. It is an unauthorized software developed by Hiraku Jira. You can go ahead at your own risk.

Step #1. Open website: on your iPhone 6s/6s Plus.

Step #2. Tap on “Install”.

Once CPUIdentifier is downloaded on your iPhone:

Step #3. Launch the Settings app.

Step #4. Tap on General.

Best Iphone 6/6S Wireless Charging Cases

The wireless charging case can be a fashion statement for young users of iPhone 6 and iPhone 6s. Still, for any working professional or a businessman, who has to travel extensively, wireless charging is essential. Communication devices like iPhones need strong battery support, especially when users are away from home or office. A power bank is a good option, but the bank’s bulk requires some space in users’ travel bags. Therefore, a wireless charging case is a better option as it doesn’t add bulk to the phone.

Moreover, users don’t need any separate space to store the wireless charging case. We have listed here some of the best wireless charging cases for the iPhone 6 for you.

Tsmc 3Nm Chip Production Can’t Keep Up With Apple Demand

TSMC 3nm chip production is well underway, with the latest process expected to be used for both the A17 chip in the iPhone 15 Pro, and the M3 destined for future Macs. However, the company told analysts that it isn’t yet able to keep up with customer demand.

Apple’s chipmaker also said that yield rates (the percentage of chips that pass quality control tests) are not yet good enough to charge the iPhone maker for every wafer produced …


Taiwan Semiconductor Manufacturing Co. (TSMC) has for many years led the world in ever-smaller processes – that is, fitting more and more transistors into a given space. The denser the transistor layout, the more powerful a chip can be for any given size.

The latest process to be offered by TSMC is three nanometer (3nm), which the company dubs N3. Samsung generally sits one to two years behind TSMC in process size, while Intel is many years away from 3nm.

TSMC’s 3nm process is expected to be used for Apple’s A17 chip, destined for the two iPhone 15 Pro models, while the non-pro models will use the older A16 chip. We’re also expecting to see the same 3nm process used for the M3 chip in future Macs.

TSMC 3nm chip production can’t keep up

The chipmaker’s CEO, CC Wei, told analysts that the company can’t yet keep up with “customer demand” – almost certainly a reference to Apple. EE Times reports:

Taiwan Semiconductor Manufacturing Co. (TSMC) is straining to meet demand from top customer Apple for 3-nm chips. The company’s tool and yield struggles have impeded the ramp to volume production with world-leading technology, according to analysts surveyed by EE Times […]

“Our 3-nm technology is the first in the semiconductor industry to high-volume production with good yield,” TSMC CEO C.C. Wei said in a conference call with analysts. “As our customers’ demand for N3 exceeds our ability to supply, we expect N3 to be fully utilized in 2023, supported by both HPC and smartphone applications.”

Can’t yet charge Apple for every wafer

Chips are produced in wafers, comprising hundreds of individual chips. Apple normally pays TSMC an agreed price per wafer, but because only just over half of the chips on each wafer are usable at this stage of production, the iPhone maker is currently paying for each usable chip.

Apple will pay TSMC for known good die rather than standard wafer prices, at least for the first three to four quarters of the N3 ramp as yields climb to around 70%, Brett Simpson, senior analyst at Arete Research, said in a report provided to EE Times.

“We think TSMC will move to normal wafer-based pricing on N3 with Apple during the first half of 2024, at around $16-17K average selling prices,” Simpson said. “At present, we believe N3 yields at TSMC for A17 and M3 processors are at around 55%, and TSMC looks on schedule to boost yields by around 5+ points each quarter.”

Although a 55% yield sounds very low, the report says that this is typical at a time when TSMC is still perfecting mass production of a new process.

2nm expected by 2025

The next major step will be 2nm chips, and these are expected to begin production in 2025. The iPhone 17 is likely to be one of the first devices to use this upcoming process.
