Thermals vs MQTT Tester

Phone running slowly, charging slowly or low brightness? See if your device is overheating using Thermals. Thermals displays your device’s thermal state, as well as how many processors are active on your device and its uptime, as reported by iOS. Thermals helps troubleshoot: • Poor performance — iOS reduces processor speed and potentially disables processors temporarily when the device is hot. • Slow charging — battery charging causes a lot of heat and iOS can limit charging speed to reduce the additional heat that might make a device too hot. • Low maximum brightness — if your device screen stays dark despite being on full brightness, it could be limited by iOS due to heat. • Manufacturing defects — if not all processors are active when the device is cool and not in low power mode. Your device's thermal state is monitored regularly in the background and recorded in the app (if Background App Refresh is enabled). Open the app or tap the widget to record a data point manually. Export the raw data to file for corroboration with Screen Time, Xcode's Instruments, or other development tools. Also an independent Apple Watch app shows the thermal status, active processors and uptime, and thermal history of your watch.

An MQTT Tester app is a software tool used for testing MQTT-based applications. It provides a graphical user interface (GUI) that allows users to interact with an MQTT broker and send/receive MQTT messages. With an MQTT app tester, users can specify the topic, message payload, and other parameters for the MQTT message, and the tester will send the message to the MQTT broker and receive any responses from the broker. MQTT Tester app can also simulate a large number of MQTT clients connecting to the broker and sending messages simultaneously, helping to identify any performance bottlenecks or scalability issues in the application. Overall, an MQTT Tester app is a valuable tool for developers and testers who are working with MQTT-based applications.
