Disabling hardware overlay is one way to make the computer use less processing power when running apps. The correct images must be exchanged and regularly checked for clipping and collisions, and this process uses significant computing power. Disabling hardware overlay reduces this need. However, disabling hardware overlay does impact battery life and the quality of graphics. However, these advantages outweigh the disadvantages. Let’s take a look at some of them.

Reduces processing power
Enabling the HW overlay layer on your mobile device reduces the amount of processing power used by apps. A hardware overlay layer allows apps to share video memory and perform auxiliary computation. This can save considerable power compared to rendering with the GPU. By default, this layer is enabled. However, you can turn it off in settings. However, you must remember that disabling it may increase the amount of power consumed by the device.
While most games and applications already render with the GPU, using the hardware overlay can help improve performance and save battery life. However, it may reduce the battery life and cause the CPU to die faster. Consequently, you’ll have to disable other features that use the GPU. Disabling hardware overlays in your Android app will save power, but it will also affect battery life. AMD claims that the GPU render engine is 50 to 100 times faster than the CPU.
Reduces graphics quality
Turning off HW overlays on your Android phone or tablet can help you enjoy smoother performance with some games, but it will also shorten battery life. The reason is that it forces the GPU to render graphics at a higher resolution, which will decrease battery life. Disabling HW overlays will also reduce the window animation and transition scale. But if you’re worried about battery life, there are some alternatives.
The first thing you should know about hardware overlays is how they work. Hardware overlays are a set of techniques used by graphics processing units to render video to the display screen. These technologies are used to display high-bandwidth video applications, which typically require constant checking and clipping, which will reduce performance and compatibility. By using hardware overlays, these limitations are overcome. The graphics processing unit (GPU) provides an efficient way to scale video and color formats.
Reduces battery life
Disabling the HW overlay layer will reduce battery life. Typically, this feature will make your application use the GPU for rendering instead of the CPU to create a smoother UI. However, this feature is only effective for 2D applications. The following are some of the ways to reduce battery usage in your Android app. By using this method, you will see a noticeable increase in performance. You can also try forcing your application to use the GPU whenever possible.
The first advantage of disabling the hardware overlay is that it saves the computer’s processing power. For example, apps need video memory exchange to create correct images. These processes use significant computer power. By disabling the hardware overlay, apps will use less power while still rendering correct images. In addition, the hardware overlay will allow the CPU to focus on other tasks, like balancing memory. It will also make the device run cooler by reducing the number of apps that need to perform the processing.
