Charger-insertion boots (androidboot.mode=charger, ABL-appended) divert to
a minimal charging.target instead of the full UI, ending the dead-battery
bootloop: ADSP charging/USB-PD runs, splash+panel killed ~6-10s in via an
initramfs hook, modem+cdsp stopped, radios/sensors suppressed, CPU capped.
Power key reboots to a normal boot, volume-up shows battery status,
volume-down enables USB ssh, unplug powers off. Measured >= breakeven on a
100mA-classified SDP port, strongly net-positive on real chargers.
Suspend duty-cycling (~13mA floor) exists behind an off-by-default flag:
resume from deep suspend intermittently kills the UFS link (hibern8 exit
failed ret=5) - do not enable until that kernel bug is fixed.
Byte-identical to the deployment verified on the dev phone 2026-08-24
(journal/power: r5 armed tests, crash autopsies, measurements).
