  • It's common for batteries to be warm from use or charging.
  • Use only manufacturer-approved chargers.
  • Battery life depends on the network, signal strength, temperature, features and accessories used.
  • This device has a Type-C charging port which allows for more data throughput and can support technologies such as Qualcomm QuickCharge 3.0.
  • QuickCharge 3.0 which can give up to 50% charge in 30 minutes (charging slows after 50% to prevent stress to the battery).
  • USB Type-C cables are reversible, meaning there is no way to plug the cable into the port upside down.
  • MicroUSB cables can't be used and may damage the port if used.
  • The use of Type-C adapters isn't recommended.
  • Some heat is anticipated and perfectly normal, though the phone should not become too warm to handle comfortably.
  • The Galaxy S8 / Galaxy S8+ support Adaptive Fast Charging and therefore is likely to get warm during charging. This is expected, especially if the device is being operated while it is charging. If the device gets warm during normal use, see the tips above.
  1. Use the provided Samsung wall charger then wait at least 1-2 mins to allow the device to charge.
  2. If the device doesn't seem to charge with the provided AC charger, connect the provided USB cable to a different AC charger (if available). If the device charges under this configuration, the provided AC charger needs to be replaced.
