AccuBattery

Battery monitoring app that measures real battery capacity and tracks actual power consumption with scientific accuracy, giving you complete control over your device's health and longevity.

Understand your battery's true condition. Every charge cycle wears down your battery, reducing its total capacity over time. AccuBattery reveals exactly how much your battery degrades with each charging session through detailed wear measurements. Set a charge alarm to remind yourself when to unplug, preventing unnecessary damage and extending your battery's lifespan.

Access precise battery usage data that Android's standard tools cannot provide. Most phones rely on manufacturer profiles that often misrepresent actual power consumption, but AccuBattery measures real battery usage directly from your device's charge controller. See which apps drain power most aggressively, understand your standby consumption, and track how frequently your device wakes from deep sleep. Get both screen-on and screen-off battery life estimates so you know exactly how long you can use your phone in any situation.

Optimize your charging setup with charge speed measurements. Find the fastest charger and USB cable combination for your device by measuring charging current in milliamps. Check charging speed with your screen on or off, and get accurate predictions for when your battery will reach full capacity.

Key features include real battery capacity measurement in mAh, battery wear tracking per charge session, discharge speed analysis, per-app power consumption breakdown, remaining charge time predictions, remaining use time estimates, deep sleep percentage monitoring, and an ongoing notification displaying real-time battery statistics at a glance.

Pro features unlock dark and AMOLED black themes to save additional energy, access to historical data beyond one day, detailed battery statistics in your notification panel, and completely ad-free operation. We're a small, independent developer focused on quality and passionate about battery science—no privacy invasions, no misleading claims, just honest insights into how your battery actually performs.

Choose Accu​Battery to stop guessing about battery health and start making informed decisions that keep your device running longer.
