In some corner cases, we will receive the DeadSystemException from BatteryStatService when invoking getBatteryUsageStats() method, since it will encounter the binder transaction too large error. Before the root cause is resolved by the BatteryStatService team, we have to add workaround protection in the app side to avoid Setting is crashed.
