The more significant change, however, comes from the improved efficiency of the new Apple A18 chipset and probably some under-the-hood improvements in iOS 18.
The transmission is a device that converts the power from the engine into driving force and transmits it to the wheels. Inside, many different types of bearings are working together, each utilizing their own strength, and inside the individual parts of a car there are also a great many bearings in use.
The Apple iPhone 16 starts at €949 and it's a great premium compact phone - it delivers in all areas that matter - design, screen, battery life, speakers, performance, and camera.
At the differential gear, gears attached to the pinion shaft (the shaft connected to the transmission) and the shaft on the wheel end interlock at a right angle. Bearings support both the rotation of the shafts and the force being applied by the gears.
The iPhone 16 is the faster phone of the two with a better ultrawide camera and faster wireless charging. The battery life has gotten better, too, and the durability has been improved if we believe Apple. You now also get the Action key and the Camera control.
Sometimes we want to drive faster, or we need a large amount of driving force such as when driving uphill. It is necessary to achieve a driving force appropriate for the driving circumstances.
If you would like to know more about those bearings used in cars that we did not introduce on this column, please click the link below.
Just as the gear and the shaft have a different number of rotations, the needle roller bearing (a combination of needle rollers and cages) is mounted between the gear and the shaft, and rotates between the inside surface of the gear and the outside surface of the shaft.

In our tests, the new Apple A18 CPU inside the iPhone 16 does score about 20% more than the A16 inside the iPhone 15. There is also between 30% and 60% jump in GPU performance depending on the 3D test.

The combined tapered roller bearings simultaneously support both the radial and the axial load (in both directions), and by maintaining the correct interlocking of gears transmit a large amount of driving force to the wheels on both sides.
In a manual transmission, gears remain in rotation and interlocking with each other at all times.In order to convey the appropriate driving force to the wheels for the speed we want to travel, we use the gear stick to select the gear (A) that best fits that driving force. The selected gear (A) is connected to the shaft, and rotates the shaft the same number of times.
There are various types of bearings, each with their own strengths. Do you know what kinds of machines use what kinds of bearings?
A bearing, of a type to match the magnitude of the power from the engine, is used, and it supports both the rotation of the shafts and the force being applied by the gears.
The only upgrade is the new ultrawide camera. It is still a 12MP unit. However, this year, there is a brighter lens with an f/2.2 aperture. Plus, probably best of all, it now has autofocus, which allows it to double as a macro camera for close-ups.
The A18 CPU is advertised to be 30% faster than the iPhone 15 CPU and 60% faster than the iPhone 12 CPU. The GPU should be 40% faster than the iPhone 15 and twice as fast as the iPhone 12.

There is hardly any improvement in the daylight photo quality, regardless what Apple may try to convince you. The iPhone 16 captures the same photos as the iPhone 15. They are detailed, with natural colors, low noise, and great dynamic range. The foliage rendition is not our favorite - especially if you shoot in the default 12MP.
The iPhone 16 scored a Very Good mark on our loudness test, while the iPhone 15 – a Good mark. The difference is marginal, though, and both setups sound the same.
The low-light videos from the ultrawide camera are now better - they are better exposed, with more detail and less noise.
New video options have been added to the iPhone 16 - studio-grade microphones for better audio quality, plus capabilities for spatial video and audio recording.
In this part we explained about the bearings that are used in devices that transmit power from the engine to the wheels, but there are a great many bearings used in the other parts of cars. By utilizing the strengths of each of the bearings, we increase the driving performance and safety of automobiles.In order to achieve safer and more comfortable driving, there is a greater and greater demand for bearings with both high functionality and high reliability.

For starters, you can compare the complete specs sheets or directly continue with our editor's assessment in the following video or in the text further down below.
In order to transmit a different driving force to the wheels for the changed situation, we use the gear stick to disconnect the connected gear (A) from the shaft and select the gear (B) that best fits that driving force. The selected gear (B) is connected to the shaft, and rotates the shaft with the same number of rotations.
How to tell which wheelbearingis bad while driving
In this part, we will explain how bearings are used in the transmission and differential gear that transfer power from the engine to the wheels.
In this part, we will introduce the bearings used in cars, as "Part I" of our introduction of the applications of bearings.
In Part 1, we introduced the idea that, in the majority of cars using conventional engines, there are usually around 100-150 bearings at work.Part 1: What Are Bearings? Let's learn about the basic functions of bearings!
Well except from the different camera layout I don't see anything different. And I'm reasonably interested in Tech. Apple has become so complacent.
To sum things up, the iPhone 16 arrives with a new chip with the promise of AI capabilities down the line, an improved screen glass, expanded camera capabilities, and faster wireless charging. There is also the added Action key and the new Camera control. But all this fits on a specs page - let's see how different the two devices are in real-world use.
There is also support for fast wireless charging for up to 25W via the new MagSafe charger when plugged into a 30W+ power adapter. If you have a compatible Qi2 charger, then the iPhone 16 will max out at 15W. Meanwhile, the iPhone 15 MagSafe wireless charging maxes out at 15W.

As a result, the new iPhone 16 scored a great Active Use Score - a noticeable improvement over the iPhone 15. The iPhone 16 offers 7 hours more of call time, about 4 more hours of web browsing, and 1.5 hours extra of video streaming.
The iPhone 16 supports fast wired charging, though Apple never reveals the maximum power rating. The company quotes a 50% charge in 30 min when using a 20W USB-PD charger.
However, the iPhone 15 is about €200 cheaper now and it carries much of the same qualities. Choosing between the two would depend on your budget and whether you value the extra features that the iPhone 16 can provide.
The differential gear is a device that converts the driving power from the transmission into even greater driving power and allows for different numbers of rotations for the left and right wheels.
The iPhone 16 practically borrows its main camera setup from the iPhone 15. It is quite potent - a 48MP sensor with 1/1.56" size, 1.0µm individual pixels and sensor-shift OIS. There is a bright f/1.6 lens in front of it. The same goes for the selfie camera - the 12MP shooter has already proven its salt and is equipped with phase detection autofocus as well.
The iPhone 16 and iPhone 15 feature identical stereo speakers. They are of the hybrid variety where the earpiece is one of the speakers. The other speaker is at the bottom of the phones, next to the USB-C port.
JTEKT provides the best low-friction torque tapered roller bearings in the world, which allow for an extremely small loss of driving force during rotation. On top of this, we are also making compact bearings a reality, greatly contributing to a decrease in CO2 emissions from cars.
The new iPhone chip allows all those high-end games that were incompatible with the iPhone 15 to run pretty well on the iPhone 16 and that is probably the most notable upgrade, if you are a gamer that is.
Whether it's Apple or someone else, always take the latest release and keep it for at least 7-8 years before thinking of changing it. Why the latest release? Because you'll have the longest support with it. In all the years you ha...
The iPhone 16 has a 3,500 mAh battery. Specifically, it is rated at exactly 3,561 mAh. The battery is slightly bigger than last year's iPhone 15. It's a small increase, but we'll take it.
The brighter aperture on the ultrawide camera does have an effect at night and the ultrawide photos from the iPhone 16 are brighter, with more detail and less noise.

The iPhone 16 has the same display as on the iPhone 15 – a 6.1-inch Super Retina XDR OLED with excellent HDR capabilities and high resolution, but a standard refresh rate of 60Hz. Both panels are advertised as capable of 1,000 nits of typical and up to 2,000 nits of maximum brightness.
We carried out our charging tests with a 45W PD charger to give the iPhones the best chance. Both phones took about the same time to charge. An hour on that charger refilled 85% of their iPhones and the last 15% took almost another hour even without the Optimized Battery charging option.
The photos from the main cameras we took in low-light conditions, both in 1x and 2x modes, are largely identical. The camera app did not opt for Night Mode on the iPhone 15, but nevertheless, the quality remains similar.
Below we have a few framegrabs from the videos taken by the two phones at each focal length so it's easier to compare them.
The iPhone 16 series is out now. It is only natural to ask yourself how much the new Apple iPhone 16 is better than the previous iPhone 15. And most importantly – is it worth upgrading?
This year's big upgrade for the iPhone 16 is the Apple A18 chipset, which is two generations ahead of what the iPhone 15 has - the A16. This is a second-gen 3nm chip that is both more powerful and more efficient.
Average life of wheel bearings
Even though it provides roughly the same user experience, the iPhone 16 is objectively the better phone compared to the iPhone 15.
The iPhone 16 has an identical footprint to the iPhone 15, which is hardly surprising. Both phones measure 147.6 x 71.6 x 7.8 mm. The iPhone 16 is 1g lighter than the iPhone 15 at 170g.
The Apple A18 has a faster six-core processor, better 5-core GPU with support for improved hardware raytracing. It also comes with more RAM, now 8GB.
Well, as per our display measurements, there is a minor difference of 50 nits between the two panels. For all intents and purposes, the two screens are equally bright.
There are also two new buttons on the iPhone 16 which are missing on the iPone 15 - the Action key used to be an exclusive to iPhone Pros and there is also the new Camera Control here.
For one, the new iPhone 16 should have improved durability according to Apple. It features a new generation of Ceramic Shield front, which is supposed to be 50% tougher than the previous one on the iPhone 15.
Of course, there is also the new Camera Control. It is an actual physical button with real travel when pressed. It also integrates a capacitive sensor that allows for touch and swipe interactions as well as a high-precision force sensor that detects light presses.
The driver operates the gear stick manually, in order to convert the power from the engine into a force appropriate for the situation in which the driver is driving.The manual transmission consists of shafts and gears. These parts are supported by bearings, and we would now like to introduce those bearings.
In order to increase a car's performance by, for example, decreasing the CO2 (carbon dioxide) emissions that cause global warming, or reducing the number of breakdowns, bearings becomes more and more important.
Transmissions can be classified into two broad categories: manual and automatic. In cars with manual transmissions, a gear stick used to operate it is installed next to the driver's seat.
Thanks to the new chipset, you'd also get access to the Apple Intelligence feature once they are released - as long as you reside in a supported region (outside the European Union and China).
