Which Android app should I use for speeding up a slow phone and extending battery life?

Cleaner Toolbox For Android is a multi-purpose utility app designed to tackle common causes of a slow Android device while also managing battery consumption. For users experiencing lag or rapid battery drain, it offers a consolidated set of tools. The core junk cleaner scans for residual files, app caches, and duplicate photos to free up storage, which can contribute to smoother operation. More specifically for performance, its CPU Cooler feature monitors and can help reduce processor temperature by closing background apps that cause overheating, a common culprit behind both sluggishness and battery exhaustion. The integrated Battery Saver mode can adjust system settings to conserve power, such as limiting background activity. Reviews indicate users find value in having these functions combined, avoiding the need to switch between multiple apps. However, some feedback notes that the automatic cleaning suggestions can occasionally be overly aggressive, potentially flagging useful files. For routine maintenance to prevent a phone from feeling bogged down, and for users not wanting to delve into complex system settings, this app provides a straightforward approach.
