Which iOS version "consumes" the most battery from iOS 10 to iOS 14?

-

 

Apple has said that each new version of iOS like iOS 14 is always better than the previous version, in both functionality and usage time. However the reality is like.

Not long after Apple officially released iOS 14 to all users, the YouTube channel iAppleBytes did a number of exercises to compare the actual battery life between iOS 10, iOS 11, iOS 12, iOS 13 with iOS. 14.

Interestingly, these tests were performed on an iPhone 6S - the device is very old but still used by many people. Therefore, the feasibility and practicality of the test are very high.

Prior to the test, these iPhones were set to 25% screen brightness, auto brightness turned off, all devices using the same settings and connected to the same hotspot. counter.

Which iOS version "consumes" the most battery from iOS 10 to iOS 14?

The results from the test show a quite significant difference, especially the iOS 12.1 version shortens the usage time of iPhone 6s by only half compared to other versions.

Thereby, iOS 10.3.3 is considered the best battery life maintainer, with 3 hours 32 minutes. Behind respectively iOS 11.4.1, iOS 13.7, and iOS 14. Thus, iOS 14 is indeed having battery problems when inferior to almost all previous iOS versions.

In fact, right at the time iOS 14 was released, posts complaining about the error of this version were flooding social networks, as well as major technology forums around the world.

The test also disproves Apple's claim, with “every new iOS version will have better performance”, when the benchmark results are quite different. Notably, iOS 10 is also the highest performing version (score: 2120), and iOS 12.1 is the lowest performing version (score: 1130).

However, it should be noted that this test is not necessarily accurate when applied to higher-end iPhones. In addition, these metrics are not obtained due to actual usage, but are evaluated by Benchmark software.

Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

-
Image
PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a...

N-Channel MOSFET High-Side Drive: When, Why and How?

I had previously shown how to drive N-channel MOSFETs in low-side configuration. You can find the tutorial here: http://electel.blogspot.com/2016/12/low-side-mosfet-drive-circuits-and_23.html I’ve been requested to write a tutorial/article regarding high-side MOSFET drive. So, here I’ll talk about N-channel MOSFET high-side drive. Let’s first look at the common low side configuration.  Fig. 1 - N-channel MOSFET configured as low-side switch Now let’s look at a MOSFET configured as a high-side switch. Fig. 2 - N-channel MOSFET configured as high-side switch You can quite easily see the difference between the high-side configuration and the low-side configuration. In the low-side configuration, the load is connected between the drain and +V, while the source is connected to ground. Thus, the gate drive is referenced to ground. So by applying a voltage of >7V (for Power MOSFETs) or >4V (for Logic Level MOSFETs), the MOSFET can be fully turned on. Now let’s talk about the high-si...

Low-Side MOSFET Drive Circuits and Techniques - 7 Practical Circuits

Image
In many circuits, it is necessary to use MOSFETs for switching. In many cases, the MOSFET drive signals are generated by microcontrollers. In other cases, they are generated by ICs – PWM controllers, timers or any IC in fact. However, MOSFETs cannot always just be connected to the drive signal and be expected to work properly. Due to the construction of the MOSFET, driving it is not the simplest of tasks, especially for beginners. There are many users who regularly ask for help on MOSFET drive related issues or problems on different blogs, websites and forums. So, here I will show some MOSFET drive techniques/methods for MOSFETs configured as low-side switches. Before I head on to MOSFET drive, let me just tell you what a low-side switch is, in case you don't know. When the MOSFET (that you're using as a switch) sinks current, it is a low-side switch. The load will be between the drain and +V supply. The source will be connected to ground. Gate will be driven with respect to gr...
