About Battery Doctor (Battery Saver)
Battery Doctor (Battery Saver) helps you extend your device's battery life by monitoring power consumption and closing unnecessary background processes. Get real-time estimates of how much charge remains and plan your usage accordingly.
Background apps drain battery even when you're not actively using them. This app identifies and stops power-hungry processes running in the background, freeing up resources and extending your battery's runtime. The process-killing tool is the core feature for meaningful battery improvements—close what you don't need and reclaim hours of talk time.
Know exactly how long your battery will last before planning your day. Check estimated runtime for specific activities: see how many hours you can stream video, browse the web, or play games before your device runs out of power. This helps you decide when to enable power-saving modes or charge up.
Battery Doctor (Battery Saver) works on Android 4.0 and higher, giving you battery insights and control across a wide range of devices. Monitor your battery health, understand what's consuming the most power, and take action to improve performance when it matters most.
