40-80% Battery Charge Saver

40-80% Battery Charge Saver is a battery optimizing app that limits phone charging to 40-80% to extend battery lifespan. It stops charging once the battery level hits 80% and only starts charging again when it drops to 40%.

What is 40-80% Battery Charge Saver?

40-80% Battery Charge Saver is an Android app developed specifically to extend the lifespan of lithium-ion batteries in phones and tablets. It works by limiting how much the battery charges, avoiding keeping it constantly at 100% which can degrade battery capacity over time.

Once installed and enabled, the app allows you to set a lower limit (usually 40%) and a upper limit (usually 80%) for your battery charge level. When your battery level hits the upper limit while charging, the app will automatically stop the charging. Charging only resumes when the battery level later falls to the lower limit as you continue using your device during the day.

By staying within 40-80% most of the time instead of constantly at 100%, lithium-ion batteries last through more charge cycles before needing replacement. This avoids losing maximum battery capacity early which often happens with normal smartphone use.

Overall, 40-80% Battery Charge Saver maximizes your battery lifespan by intelligently managing the charging process. It requires minimal input once configured, making it convenient for long-term use. Most users can expect to add several months if not 1-2 years extra lifespan to their phone battery before needing replacement.
