WM system kernel is not the latest fast, and the fastest is not power saving, thank you in advance,

The new core can make full use of the overall performance of the hardware, that is, it can improve the overall performance of the hardware. Often, the data read and write speed of the new kernel, floating-point computing, etc. are improved compared with the old kernel, and the system runs relatively smoothly.

However, not all phones have the fastest new kernels, and this is also related to other parts, since the kernel is only a part of the ROM and the performance of the system is determined by the overall performance of the ROM, and this aspect is the software aspect. As for hardware, the performance of the same kernel version is different for different models, just like our computers, not all systems are newer and faster. This assumes that the overall performance of the hardware is good.

It's like the Vista, the old machine is hard to run, and the one with a high configuration will be smoother than the XP.

At the same time, new cores are likely to be related to power management, and the battery life is different in different power management modes. The current one has a longer standby time than the WM5, which is more power-efficient. However, it is not absolute, as mentioned above, the same version of the kernel will also be different in the synthesis of the ROM, which also makes the power consumption on the same machine different.

1 Apparently not. It is also related to hardware configuration, CPU, and memory.

There is a little relationship with 2 electricity charges. The faster the processor, the more power consumption is likely to be. The main cost of electricity is the screen.

1 all used for positioning is not bad (slow), navigation is less than half a day on the battery, ready battery or car charging (if not open, I charge a day, I am WM machine originally consumed electricity) If it is just for doll play, it is not a GPS mobile phone with software can also be located It is to cost some traffic.

It's just that it consumes a lot of power during the search for satellites, once you find a satellite and the positioning is successful, it will not consume so much power, generally speaking, 5 hours of navigation is not a big problem, and if you spare 2 batteries, one day is enough.

Obviously it can't be opened, n consumes power... It doesn't feel useful, it's just fun, and the novelty will be wasted as soon as it passes.

No, mine is okay.

Have you done bare metal development on your arm? It is a variety of underlying drivers under arm, interrupts, timers, LCD, Ethernet, ** interface, serial port, SPI, I2C, I2S, etc. Personal suggestion is to get these drivers done first and then engage in the linux kernel.,As for your question,I think of course the more in-depth understanding of the kernel, the better.,But you can also do linux+arm driver development without a deep understanding.。。。

It's okay to do a bare drive without going deep, but if you do a kernel driver, you have to go deep.

The ghost system is based on the original system to delete most of the content that is not commonly used, and then add some other software, crack the activation function of the original system, automatically activate after installation, and integrate common hardware drivers into the system, this kind of system is generally packaged with ghost software.

This kind of system cannot be patched, as it may fix the activation function after installation and cause prompt activation. XP and Win7 have different kernels and cannot be used universally.

The next optimizer. Optimize the system.

You can delete some unused languages, and there is also a system backup!

In fact, you can just delete the things on the C drive.

You can also put the contents of the C drive on other disks.

If you want to delete the words go to my computer-(are you xp) on the left there is the Add Removal program click him.

A whole bunch of stuff will come out, press delete and you can delete it.

You see if there's anything you don't need to use, just delete it.

But if there's something that you haven't seen or that you're not in, then it's best not to move it, it's probably system-operated.

You can also delete some files from a movie.

I suggest you don't use your computer's My Documents, My **, etc., because those are all on the C drive, you can create a few new folders on the D drive, or the E drive, and create a few new folders for your My Documents, etc., and then put your files and so on in there.

Go to the D or E drive, right-click and select New-Folder on it.

The upstairs arguments are too complicated. It's not easy to understand all at once!! Check this out!!

The seven reasons why computer usage slows down are all analyzed.

Landlord, you don't understand mobile phones. If you are talking about those business people, it is estimated that they are business people who don't know how to use smartphones, if you don't know how to use smartphones, why not buy S40 Nokia, ** is cheap. Android's office and entertainment performance are definitely much higher than Nokia's, and anyone who has played these two systems should know it.

If you talk about traffic, I am a post-90s generation, and I often play with my mobile phone and surf the Internet, 150M of traffic a month is enough, if it is those business people, how can there be so much effort to surf the Internet. General work needs to go online and enough data, Android has wifi, why do you need to use mobile networks all the time? The landlord is too radical, if you want to be smart, Android or Apple.

If you don't need it, the Saipan S40 is very good! Moreover, if Nokia has such a large hardware support, presumably the landlord said that Nokia is not good, the landlord can take Nokia's Android mobile phone from the hardware and standby time comparison to know, Nokia can not be said to be as power-saving as you imagined!

Android just brings a better user experience, making it easier for people to browse the web and find what interests them, and you're too aggressive.

Practical or not depends on which field you use it more!

The so-called traffic problem depends on how you use it I myself use Android because it supports more software, and it is cheap (I can't afford i wind) and there is a software to send most of the mobile phone text messages in the world without charging money, just use a little bit of traffic, not chat software, for example, my mobile phone has this software, your phone does not have it, I send you a text message, you can still receive super cool, you must know that it is sent to the world!!

Right-click on My Computer, select Properties, and then select"Advanced", in the selection of the inside. Performance. Later set up and then customize!

Then select Error Reporting to disable Error Reporting!

Then select System Restore and turn it off!

Then select Auto-update and turn it off!

And then sure! That's it!

Introducing you to a piece of software"Optimizer"

With Super Bunny! Very easy to use!

Don't be so troublesome, go to the next Super Rabbit or Optimization Master to automatically optimize it, it's very simple.

Drivers are part of the kernel, but they are quite different from system development. In system development, the focus is on understanding CPU instructions and hardware architecture, and then designing a set of systems for allocating hardware resources through software programs, while drivers usually play a role in the bridge between the system and specific hardware, of course, there are exceptions to the concept of virtual devices or filter drivers. From the perspective of the application layer, this kind of development belongs to the underlying development.

But from the hardware layer, these are not so low-level.

At present, most enterprises are engaged in system transplantation or custom hardware driver development, but to do such a job is not very quick to get started, and it takes a long time to learn, really to wait until the technical level from zero to be able to adapt to the needs of the work, it is estimated that it will take 3-5 years, and it depends on the individual's opportunities and mentality.

I thought, what's the point? Drivers are divided into two categories, one is compiled directly into the kernel after compilation, and the other is compiled into an independent module and needs to be called when hardware drivers are needed.

Upstairs is correct, however, the system development is really unclear, could it be the middle layer of some large system?
