Abnormal battery usage - how to diagnose?

[sclsj]

iOS device model, version and app version

Model Name: iPhone 15 Pro Max
Software Version: 17.2.1
App version: 2025.2 (2025.1178)

Home Assistant Core Version
2025.7.3

Describe the bug
iPhone heats up significantly when idle at front page for ~10 min, with significant battery usage

To Reproduce
Leave on Home

Expected behavior
Visible portion is updated at default frequency. Invisible portion is lazy loaded. Low CPU usage.

Question
I'm not sure if this is a bug or just something about my configuration (sensor number, sampling rate, etc.), since this doesn't occur when I started using HA (can't remember when this happens). What are some steps I can take to analyze what is taking CPU? For example, is it rendering a specific graph or pulling specific data too frequently?

Additional note: on macOS (m1) the HA app from App Store is also taking 100% cpu (unix style), so potentially not an issue with my iPhone.
