## What is PhoneGauge?

PhoneGauge measures what really happens when your iPhone heats up.

■ Thermal Throttling Test
Runs a steady workload on every CPU core and charts, second by second, how much performance drops as the device heats up.
· 3, 5, 10 or 15-minute tests, graded S to D
· Final and lowest performance, time to "hot", battery used
· Tag runs with case on/off and charging to compare conditions
· Share your result card as an image

■ Activity Log
Start a log before gaming, filming, watching video, navigating or video calling.
· Elapsed time on the Lock Screen and Dynamic Island
· A report when you finish: battery used, drain per hour, peak thermal state
· Compare average battery drain by activity

■ Charger Compare
Name your chargers and cables, measure how many percent per minute each adds, and see them ranked. Spot slow cables at a glance.

■ Heat Journal
Logs what was going on whenever the thermal state changed (charging, CPU load, screen brightness, data transfer, current activity) to help you find what makes your phone hot.

■ Live Details
Per-core CPU, memory, network speed and traffic, storage, and Home Screen widgets.

■ Honest by design
iOS doesn't give apps exact temperatures or other apps' usage. PhoneGauge only uses the 4-level thermal state iOS provides and values it measures itself, and never claims to do what iOS doesn't allow.
