Many believe fully draining their phone's battery helps "calibrate" it, and that recharging at low percentages harms battery health. But is that really true? Let's dig into the facts.
Modern phone batteries do not need to be calibrated or discharged fully. They use digitally controlled charge cycles not harmed by topping up before empty.
What degrades batteries over time is exposing them to high heat and voltage. Charging at very low battery levels creates both due to higher electrical loads.
For maximum longevity, recharge frequently before reaching low battery rather than running empty. Try to stay between 40-80% charge whenever possible.
While avoid fully discharging daily, the occasional 0-100% cycle helps devices accurately gauge battery capacity.
Always use the included, compatible charger. Avoid prolonged charging sessions if the battery gets hot, as heat accelerates aging.
Plan to replace batteries after 500-800 charge cycles, usually 2-3 years of use, when capacity noticeably declines.
For heavy use cases, a battery case can provide supplemental power and take charging strain off the internal battery to extend lifespan.
Don't wait until empty - for optimal longevity, frequently charge your phone to 40-80%. But the occasional full cycle is fine too! Replace after 2-3 years.
