Tips for maintaining the new battery

To ensure your Samsung S7’s battery performs optimally after replacement, consider the following tips:

  • Avoid Complete Discharges: Try not to let your battery drain completely before recharging. Frequent full discharges can shorten battery life.
  • Optimize Charging: Charge your phone when it drops to around 20% battery level. Avoid letting it reach 0% or keeping it constantly at 100% as this can stress the battery.
  • Keep It Cool: Excessive heat can damage the battery, so avoid leaving your phone in hot environments or in direct sunlight for extended periods.
  • Use Official Chargers: Using third-party chargers may damage the battery. Always opt for official Samsung chargers to ensure compatibility and safety.
  • Turn Off Unused Features: Deactivate Bluetooth, GPS, and Wi-Fi when not in use. These features drain the battery even when idle.
  • Regularly Update Software: Software updates often include battery optimization features, so keeping your phone up-to-date can help prolong battery life.
  • Monitor Battery Usage: Check which apps are consuming the most battery power in your phone’s settings. You can then adjust settings or uninstall power-hungry apps.
  • Consider a Power Bank: If you often find yourself in situations where charging is not possible, carrying a power bank can be a lifesaver.


That’s it! By following these simple tips, you can ensure that your Samsung S7’s new battery lasts longer and performs at its best. Remember to keep an eye on your battery usage, avoid extreme charging levels, and use official chargers for optimal results. With a little care and attention, you can enjoy a longer battery life on your Samsung S7. Happy charging!
