What to do when my android's battery is drained?

When your Android's battery is drained, first connect it to a charger and allow it to charge for at least 15-30 minutes before attempting to turn it on. If it doesn't power on, try a different charger or cable to rule out charging equipment issues. Once it powers up, avoid using battery-intensive apps and consider enabling battery saver mode to extend usage. If the battery frequently drains quickly, consider checking for software updates or battery health issues.
