• Time to full is now right with slower chargers. With a 5 to 12 W charger the last part of a charge was shown as taking hours; it now matches how the battery really finishes. • Your phone learns its charging curve again over the next few charges, so estimates settle in quickly.
WattWave shows how fast your iPhone is charging and how fast your network really is. CHARGING POWER Plug in and the watts appear at once. WattWave works out how much power your phone draws from how quickly the battery rises and keeps refining the value while you charge. Pick your real charger or cable in Settings and it learns how efficient your setup is. The value is an estimate, because iOS gives apps no direct reading. DYNAMIC ISLAND AND LOCK SCREEN Keep power and network speed on the Dynamic Island and the Lock Screen. When you are not charging, it shows download and upload instead. Add your AirPods battery if you like. SPEED TEST Measure download, upload, delay and jitter, on Wi-Fi or cellular. Results are saved with a trend chart so you can compare networks and times of day. CHARGE HISTORY Every charge is recorded: how long, how much the battery gained and the charging speed it reached. DEVICES See devices on your Wi-Fi, Apple and others, and nearby Bluetooth devices including AirPods. Give devices names that stay on your iPhone. SIRI, SHORTCUTS AND WIDGET Ask for your charging power or run a speed test by voice. A Home Screen widget shows your last charge and last speed test. PRIVATE BY DESIGN No account, no ads, no analytics. Everything stays on your iPhone, and one tap in Settings deletes it. Try everything free for 3 days. Then unlock WattWave once, with no subscription.
