To maximize the lifespan of your budget backup battery for an iPhone, consider the following tips:
- Regular Charging: It’s essential to keep your backup battery charged to about 50% when not in use. This prevents the battery from entering a deep discharge state, which can significantly reduce its overall capacity and lifespan.
