Perhaps the simplest way to improve the performance of a tablet without making any radical changes to how you use it is to flash a different kernel. A good custom kernel to use, and one that is available for most devices, is franco. You need the paid version from the Play Store to fully customise its settings.
The kernel is a slightly abstract concept in that it is involved in literally everything your tablet does, but has no real consumer application. The stock kernel used on your tablet will have optimised by the manufacturer to provide a balance between speed, stability and battery life. A custom kernel will come with its own default settings, based on the priorities of the developer, and many have a companion app that can be further used to tweak the settings to your own priorities.
These set how the processor functions under different types of usage, such as how quickly it will ramp up to full speed when required and how quickly it drops back down again. These are normally accessible through a simple drop down list in the kernel management app, and have a noticeable effect on speed, battery and smoothness.
These set how the processor reacts when required to perform certain tasks.

The OnDemand setting will, for example, ramp up to maximum speed quickly and reduce slowly, which is great for mulitasking but may be heavy on the battery. Conservative runs as slowly as possible, boosting battery but affecting speed. Most kernels enable you to change the clock speed of a processor.
Increasing it will make the phone faster but potentially less stable. Contrary to popular belief underclocking is unlikely to have any real impact on your battery life.
Kernels generally have two types of task scheduler, which balance how resources are used. Stock kernels use CFS, which is optimised for multitasking and ensures equal performance across your apps. BFS prioritises the foreground app and can be great for gaming but less effective for regular use.

I've linked your XDA thread below the graphs that I've used from your guide. Lagfree will give better battery life. Lionheart is better at everything else. Awesome mate. Well put and now I have a better understanding of how all of these governors actually work. Thanks man!
I find Chill on clusters on big. Awesome performance and screen off time is minimal. Nice article. Nice Blog Very goood information i got from your blog. Thank you and Share some more android stuff here. Ow, how does mpdecision is the best for performance and battery life? I don't think that list is right. It can be a little too aggressive with switching on cores. I think you are right to think that technically it isn't the best in both cases, so I might have to do further research! Very informative, thanks for the hard work.Best wow graphics settings bfa
Now I can really explore kernel auditor. One question as a noob,can i set hotplug driver to mpdecision? Or is it actually default? Mine Isn't qualocom device Or between intelliplug and thunderplug which one is better?
Finally,between elementalx and interactive which is better? Tanks for comparison :. Post a Comment Please respect the admin of the website and don't post spam!

There are many CPU governors available on android, but there are some important things people should look out for before selecting their new governor:. This all depends on if the governor is biased towards performance or towards battery life.
Balanced governors tend to be on the middle-ground providing optimal speed when required. If the governor is biased towards battery life, the battery should drain slower. If the governor is balanced, then it will try to provide optimal performance while trying to be battery friendly when possible.
This also depends on usage patterns and other factors such as background applications or wakelocks when your CPU is on even though your screen is off. Stability - The stability of a governor is dependent on a number of factors like how well the developer has implemented the governor and can vary between different devices.
One governor may work well for a specific platform but may not work well on others.XDA Developers was founded by developers, for developers.

Important Links Source Code!No matter how fast our phones are, there is always room to make them be a little bit faster. Fortunately, Android lets you do just that. The process is called overclocking and it simply means forcing your CPU to run a bit faster than it normally does. Here's how to overclock your Android phone and supercharge it.
Hardcore PC users might already be familiar with overclocking. The same possibility exists for Android: you can tell your CPU to run faster than the manufacturer's recommended settings. The process is surprisingly easy and can give you as much as 30 percent more power.
Here's everything you need to know:. The kernel is a computer program that is the core of a computer's operating system. It is often one of the first programs loaded when you start up a computer device, sometimes referred to as a bootloader. It does this in a protected part of the memory, known as the kernel space Android uses the Linux kernel, but you can change this if you root your device.
First I need to give you the standard warning. Increasing the clock speed of your CPU generates more heat and drains more power. It isn't likely to set your phone on fire or kill your battery, but excess heat production can create instability and affect your battery life.
The key is to take your time. Don't try to jump to a 30 percent increase in clock speed straight away.
Take it slowly and evaluate how stable the system is with each increase. If things get weird, back off to the last stable clock speed. Happy with that? Let's proceed. The only thing you need to tweak the CPU settings of your Android phone is a kernel that supports overclocking. Overclocking is a staple of the modding community, so there is no shortage of good kernels to choose from. You just need to get the right kernel for your particular phone model. First, find the model number of your phone.
You'll also want to make a note of the version of Android you're running. Your phone will also need to be rooted in order to overclock your CPU.The vast majority of custom kernels allow various modifications like selecting your governor, adjusting the maximum clock frequency, and much more.
These paramters can be changed by executing commands through ADB or by using one of the kernel control applications created by various kernel developers here on XDA. Applications that let you change kernel settings are often limited to a few basic options or are paid-only. If you are looking for a free app with nice design and a long list of settings to change, XDA Recognized Developer and Contributor Grarak might have something that can come in handy. Kernel Adiutor is an application that manages kernel parameters on rooted devices with Android 4.
Settings are also grouped in the nice looking menu in order to prevent the experience from becoming too overwhelming. Before using this app, please note that setting some values may cause instability to your system or even cause hardware damage. In other words, please use this application with caution. You can download the app or contribute to its development by visiting the Kernel Adiutor application thread. Want more posts like this delivered to your inbox?

XDA Labs Labs is an independent app store that gives developers full control over their work.Higher values means CPU polls less often.
For lower frequencies, this could be considered an advantage since it might not jump to next frequency very often, but for higher frequencies, the scale-down time will be increased.
Setting a higher value will bias the governor towards lower frequency steps. Use this if you want CPU to spend less time on higher frequencies. A better alternative would be to underclock to a lower frequency than using powersave bias.Hells angels 2019
Default behavior is fast switching to lower frequencies 1. Because triggering up-threshold will again cause CPU to scale up to max frequency. When set to '0' its defaultall processes are counted towards the 'cpu utilisation' value. When set to '1', the processes that are run with a 'nice' value will not count and thus be ignored in the overall usage calculation.
This is useful if you are running a CPU intensive calculation on your laptop that you do not care how long it takes to complete as you can 'nice' it and prevent it from taking part in the deciding process of whether to increase your CPU frequency. Now it's user-configurable. Allowed values 10, toThereafter, scaling up is less aggressive. Thereafter, scaling down is less aggressive. Zero disables and will calculate ramp down according to load heuristic.How To Reduce Lags On Android - Using Entropy ( Kernel Adiutor ) - [ ROOT ]
When above the ideal frequency we always ramp down to the ideal freq. Zero disables and causes to always jump straight to max frequency. When below the ideal frequency we always ramp up to the ideal freq. You can change this value to anywhere between 0 and where '0' will effectively lock your CPU at a speed regardless of its load whilst '' will, in theory, make it behave identically to the "ondemand" governor.
Default is the maximum speed allowed by the policy at governor initialization time. Default is uS.
Manage Kernel Parameters on Android with Kernel Adiutor
A deferrable timer is used, such that the CPU will not be woken from idle to service this timer until something else needs to run. In general, the lower the target load, the more often the governor will raise CPU speeds to bring load below the target.
The format is a single target load, optionally followed by pairs of CPU speeds and CPU loads to target at or above those speeds. Colons can be used between the speeds and associated target loads for readability.
If speeds are specified these must appear in ascending order. Higher target load values are typically specified for higher speeds, that is, target load values also usually appear in an ascending order. The format is a single delay value, optionally followed by pairs of CPU speeds and the delay to use at or above those speeds.
Colons can be used between the speeds and associated delays for readability. For example: uses delay uS until CPU speed 1. For platforms that consume additional power at idle when CPUs are running at speeds greater than minimum, this places an upper bound on how long the timer will be deferred prior to re-evaluating load and dropping speed.
A value of -1 means defer timers indefinitely at all speeds. Default is zero. The higher this value, the higher the frequency to jump will be when the above conditions are satisfied. This value should be less than your device's max CPU frequency. This ensures that the governor is not too aggressive in scaling down the frequency and reduces it just because some background process was temporarily causing a larger number of wakeups.
