Battery drain is rarely one obvious app
A browser can hold dozens of tabs. A class project can leave a server behind. A video call can end while a sleep assertion does not. Battery Hog brings those clues beside total power draw and estimated remaining runtime.
Plan your runway
See current battery level, total live draw, and a forecast before a long class or study block.
Catch leftovers
Find apps, development workloads, and sleep blockers that kept working after you moved on.
Learn your pattern
Use charge and drain history to separate one bad session from a recurring habit.
Keep data local
No account or monitoring analytics. Update checks are manual unless you opt into periodic checks.
Start with the least disruptive move
Battery Hog is designed to explain before it acts. Close an unused tab group, stop a stale local server, mute an unhelpful suggestion, or leave the workload alone when it matters more than the battery.
