The battery life improvements are noticeable! Once you have closed all unnecessary apps your phone should last a little longer.
KillApps is an application that is designed to shut down all the applications on your phone with one touch. The goal is to free up resources on your device and thus improve its performance and save battery life.
If you are someone who forgets to close apps and leaves them running in the background, this application will be extremely useful to you, since it stops everything at once, running applications, tasks and background services.
KillApps allows you to speed up your mobile's response speed, cool it down by reducing CPU effort and conserving your battery longer. Its developers also ensure that the app preserves your privacy and does not collect any data.
