…he play time it leaves: "60 fps · Busy" over "75% · 1h20 left". The heat is NSProcessInfo's thermal state named for what it means (nominal, fair, serious, critical → Normal, Busy, Throttling, Overheat); the percentage comes from IOKit's power sources in 1 % steps, as the status bar shows it, or from UIDevice's 5 % steps when those are refused; the time is measured from the first step down to the latest, again after charging or the background. The label's timer runs in the common run loop modes, so it keeps updating while a touch is tracked (replaces PR seedds#1976) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

… Heat and battery (DM_SHOW_HEAT_BATTERY, off by default) sits under Frame-rate counter and is drawn only while the counter is on (needs=DM_SHOW_FPS=1); without it the counter is the frame rate alone, as before. The in-game menu turns it on and off at once, and turning it on starts the battery's measurement again Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

A shorter redo of #1976. The counter reads:
NSProcessInfo.thermalStatewith plain names: nominal → Normal, fair → Busy, serious → Throttling, critical → Overheat.dlsym, since they are in the iOS runtime but not its SDK). If the sandbox refuses them it usesUIDevice.batteryLevel, which moves in 5 % steps on current iOS. The log lineframe-rate counter on (battery in … steps)says which one is in use.…until then, andchargingwhile plugged in. Charging, a level that goes up, or time in the background starts the measurement again.DM_SHOW_HEAT_BATTERY, off by default), right under Frame-rate counter and drawn only while it is on. Off, the counter is60 fpsalone, as before. The in-game menu switches it at once.Checked:
compile_check.py(262 files, 0 failed);test_launcher_settings,test_player_env,test_settings,test_env_switches,test_docs.Not checked: an iPhone. Still to find out on a phone: whether IOKit's power sources answer inside the app sandbox.
