Phone Health Checker

Your phone deserves an honest second opinion.

Battery capacity, cycle count and health trend, per-core CPU and RAM, storage by category, sensor tests, temperatures, network quality and a benchmark score: the real data your phone already reports, in plain language and tracked over time.

Overview

Most Android phones expose hardware sensor data and system metrics through standard APIs, but the information is scattered across settings menus and not presented in a way that is easy to understand. The app pulls that data into a single dashboard, with clear explanations of what each metric means and when it should be a concern.[1]

History and motivation

Kalenux describes the phone-health category as a trap: the top results are “boosters” and “cleaners” that invent problems to sell a fix, fake virus warnings, claims that the battery is dying, pretending to free memory that was never full, while the real information sits in developer menus no normal user is expected to find.[1]

“No fake alerts, no upsell, no manufactured panic: just a clear, honest picture of your phone’s health.”[1]

Battery health

Battery health is the central feature. The app reads capacity, estimated health percentage, charge-cycle count, temperature, charging voltage and charging current, and tracks them over time so users can see degradation: a battery at 95% six months ago and 78% now shows a clear curve. Kalenux notes this longitudinal data is not available in default Android settings.[1]

Diagnostic modules

Module	What it checks
CPU and RAM	Usage per core, clock speed, total and available RAM, memory pressure, in real time
Storage	Internal and external storage by category (apps, photos, videos, audio, documents, other); flags critically low space
Sensors	Gyroscope, accelerometer, magnetometer, barometer, proximity, ambient light and fingerprint: whether each responds correctly
Temperature	CPU, battery and, where available, board temperature; alerts when outside safe ranges
Network	WiFi and mobile speed, signal strength, ping latency and DNS resolution time
Benchmark	Standardised CPU and memory benchmark producing one score, comparable against the platform average

Design principles

The app reads the real sensor data, battery metrics and system statistics the device already reports, presents them in plain language and tracks them over time. It helps distinguish between device problems and network problems, and avoids the scare tactics common in the category.[1]

Reception

On the Kalenux product page, Phone Health Checker holds a rating of 5.0 from one moderated review.[3]

Instantly diagnosed my battery problem★★★★★

“Ran the check and immediately identified my battery was degraded to 68% capacity. Saved me a trip to the repair shop to find out what I already found out in 2 minutes here. The sensor tests are also surprisingly thorough.”
