Battery Protection Optimization: Control When Charging Resumes
I’d like to suggest adding a “Start recharging at” option to complement the current Maximum Battery Protection feature.
Right now, we can set the phone to stop charging at a specific percentage, but we can’t choose the level at which it should resume charging. In my own tests, I often find my phone sitting at around 79% while still on the charger, with the battery reaching 38°C. If the device could rest longer before resuming charging — for example, only starting again at 75% — it would stay significantly cooler.
Lower temperatures are directly linked to better long-term battery health. Allowing users to customize both the stop and start percentages would reduce unnecessary charge cycles, improve temperature management, and ultimately extend battery lifespan, all while keeping the experience flexible and user-friendly.
