Amply

Amply shows you, in real time, how much current is flowing into or out of your battery — so you can finally know which charger and cable combination charges your phone fastest.

Plug in a charger and watch the milliamps. Swap the cable and compare. That slow charging you've been blaming on your phone? It might be a worn-out cable — now you can prove it.

⚡ LIVE CURRENT METER
• Instant charging/discharging current in mA, updated up to twice per second
• Rolling minimum, maximum, and average readings
• A live graph of your charging session, right on the main screen
• Battery level, voltage, temperature, health, status, power source, and battery technology at a glance

🏆 CHARGER TEST
Stop guessing — measure. Run a 60-second benchmark on any charger + cable combo and save the result with a name ("25W brick + white cable"). Amply ranks your saved results fastest-first, so the best charger in your drawer is no longer a matter of opinion.

⏱ TIME & CAPACITY ESTIMATES
• Time to full while charging — also shown in the live notification
• Time left while discharging, based on your actual current draw
• Estimated real battery capacity in mAh, read from your device's fuel gauge

🎨 COLOR-CODED AT A GLANCE
The entire app changes color with your battery's state: green while charging, blue when full, amber while discharging, red on an over-voltage fault. You can read the situation from across the room.

🔔 LIVE NOTIFICATION
Turn on the optional monitor notification and keep an eye on the current — and time to full — while using other apps or with the screen off. Stop it anytime with one tap, directly from the notification.

📱 HOME-SCREEN WIDGET
A resizable widget shows current, battery level, status, voltage, temperature, and power source. It refreshes instantly when you plug or unplug, updates frequently while charging, and stays battery-friendly on standby.

⚙️ MADE TO BE LIGHT
• Adjustable refresh rate (0.5–5 s), °C or °F
• Measures only while you're looking — no background drain
• No ads, no analytics, no internet permission — your data never leaves the device

📋 GOOD TO KNOW
Readings come from your device's fuel-gauge chip via standard Android APIs. A small number of devices don't expose current measurement — Amply will tell you clearly if yours is one of them, and still shows the remaining battery info. Because manufacturers calibrate their hardware differently, values and estimates are best used for comparing chargers and cables with each other rather than as lab-grade measurements.

Charge smarter. Know your amps. ⚡
