Test charging speed in watts, check battery health and run a full phone test
Ampio is a charger tester and a phone tester in one app. It shows your phone's real charging speed in watts, tracks battery health over time and runs a full phone test of 15 or 26 steps, so you can check your own phone or a used one before you buy or sell it, and share the results as a report.
Is this charger or cable any good? Is my battery wearing out? Is this used phone worth buying? Does everything on it really work? Ampio answers with numbers and test results, not guesses.
Live Charging Power
• Watts, milliamps, volts and battery temperature in real time
• A gauge on a fixed 0 to 100 W scale, so 5 W looks slow and 65 W looks fast, with a label from very slow to ultra-fast charging
• Estimated time until full and a graph of the last 10 minutes
Phone Test
• Re-check a single part, like the camera or speaker, after a repair, and compare two tests side by side
• A quick test with 15 steps takes about 5 minutes, a full test with 26 steps about 10 minutes
• Every step ends as passed, failed, skipped or not supported
• Covers the touch screen, multi-touch, dead pixels, speakers, earpiece, microphone, vibration, flashlight, cameras, volume buttons, proximity sensor, accelerometer and gyroscope, charging port, light sensor, compass, fingerprint and face unlock, Wi-Fi, Bluetooth, GPS, NFC, SIM, storage speed, headphone output, infrared and battery
• You get a score and a report with the device details and every result, and earlier tests stay saved
• Share the report as an image or a PDF. It is made on your own phone and is not an independent certification
Charger Test
• A 60-second test shows how much power your phone really gets from a charger and cable
• It works best between 20% and 80% battery, and the screen stays on at a fixed brightness so results are comparable
• Each charger or cable gets a name, and a ranking compares them all
• Results can be shared as an image with a QR code
Battery Health
• Ampio compares the charge that flowed into the battery with the percentage it gained, and uses the median of your last long charges
• After 3 long charges, Ampio measures the health. Until then you see an early estimate that is clearly marked as one
• Early estimates come from the phone's own report, its charge counter, its cycle count or the age you enter
• Charge cycles and a health history chart show how the battery changes
• Android does not give apps the real battery health, so estimates can differ from the manufacturer's number
Charge History
• Every charge is saved with its power and temperature graph, start and end level, duration and mAh added
• Charging habits for the last 30 days: average start and end level, how often you reach 100%, average duration and peak temperature
• Peak temperature per charge helps you spot a charger that runs hot
• A detailed 24-hour graph of level and temperature unlocks for a day after a short ad
Alerts
• A charge alarm at the level you choose lets you unplug at 80% and go easy on the battery
• A temperature warning, in °C or °F, appears when the battery gets hotter than your limit while charging
Background Monitoring
• Live monitoring shows the watts in the status bar and records every charge
• Background snapshots every 15 minutes need no notification at all
• A built-in guide for Samsung, Xiaomi, Oppo, Realme, OnePlus, Huawei and Honor shows how to stop the phone from pausing Ampio
Widgets
• Seven home screen widgets in light and dark: compact, power, ring, bar, detail, temperature and health
Private by Design
• No account, no name, no email
• Measurements, history and test results stay on your phone
• The camera shows a live preview and takes no photo, the microphone level is not recorded and GPS only counts satellites
Good to Know
• Works on Android 8.0 and newer. A few phones do not report current, and Ampio tells you when that is the case
• Light, dark, system and AMOLED black themes, 29 languages and right-to-left layouts
• Free with ads. A one-time purchase removes them
מה חדש
• Single-part phone tests now end with their own result screen
• A shortcut to compare two tests
• A clearer charging gauge with speed bands and consistent digits, a roomier battery health card
• Flashlight and vibration tests confirm themselves
