Network issues can also impact battery life, as a weak signal forces the phone to expend more energy to connect and maintain a stable connection. This can be particularly noticeable in areas with poor reception, where the phone continuously searches for signals.
What Is the Expected Lifespan of a Samsung S9 Battery?
Best practices for prolonging the lifespan of a Samsung S9 battery include avoiding extreme temperatures, not allowing the battery to completely discharge frequently, and using the appropriate charger.
