External GNSS power stats are controlled by GPS chip side. The power stats would not update while GPS chip is down. This means that GPS OFF state residency won't reflect the elapsed off time. So only GPS ON state residency is present. Bug: 289764363 Test: dumpsys android.hardware.power.stats.IPowerStats/default Change-Id: Ic51ebef14ca131914a6a5b4ea681c739e9920d63 Signed-off-by: Darren Hsu <darrenhsu@google.com>
