WristRevive: Battery Toolkit
An evidence-based Wear OS battery diagnostic toolkit that measures real drain, compares controlled tests, and helps determine whether an ageing or unexpectedly power-hungry watch can be improved or should be repaired or replaced.
Coming Soon to Wear OS
WristRevive: Battery Toolkit is currently in active development. The features listed below represent the planned scope. Want to know when it launches?
Notify me when this launchesPlanned Features
- Estimate current drain rate and remaining runtime from low-overhead battery observations
- Review a rolling seven-day local battery timeline with diagnostic context
- Run 12-hour or 24-hour Revive Scans to establish a defensible baseline
- Classify normal active use, abnormal idle drain, workload limitations, possible post-update regressions, and insufficient-data cases with visible confidence
- Identify elevated-drain periods without pretending to provide unsupported exact per-app electrical attribution
- Run a matched Idle Drain Test before and after changing one setting or behaviour
- Compare absolute and relative drain differences using duration, data-quality, confidence, and materiality checks
- Use the Everyday Lite endurance profile to preserve essential watch functions while reviewing reversible battery-saving changes
- Follow a restoration checklist before deactivating an endurance profile
- See estimated runtime and active-profile state from a Wear OS Tile
- Add a short-text watch-face complication for estimated runtime or battery fallback
- Store scans, tests, profiles, and battery history locally with bounded retention and no cloud account requirement
Frequently Asked Questions
Can WristRevive repair a worn-out watch battery?
No. A normal Wear OS app cannot restore lost lithium-ion capacity. WristRevive is designed to measure battery behaviour, test reversible changes, and help distinguish recoverable software or configuration problems from likely physical degradation.
How is WristRevive different from a normal battery graph?
WristRevive guides a complete workflow: establish a baseline, classify the drain pattern, test one change at a time, compare matched periods, apply a purpose-specific endurance profile, and decide whether the watch remains viable.
Can WristRevive identify exactly which app used the battery?
Not reliably on a standard consumer Wear OS device. WristRevive reports supported measurements and contextual correlations, but it does not claim exact per-app electrical attribution when Android does not expose it.
Will WristRevive itself cause significant battery drain?
The watch-first design uses low-overhead, inexact background collection with bounded tests and retention. It avoids continuous sensor polling, persistent wake locks, and high-frequency network traffic.
Does WristRevive require a phone companion app?
The initial MVP is watch-first and includes diagnostics, scans, controlled tests, an endurance profile, a Tile, and a complication on the watch. A richer phone companion is planned for later development.
How will WristRevive be priced?
The current plan is a useful free tier with an optional one-time Pro purchase for deeper history, additional controlled tests, advanced scoring, profiles, comparisons, and export. Final pricing may change before launch.
