Want to protect your phone's battery? Stop doing this one simple thing

Elyse Betters Picaro / ZDNET I have spent a lot of time writing about how battery wear is a fact of life, and the more a battery is used, the more it will wear. It is a consumable item, and it will wear. Also: The best power banks you can buy But there are also things that we can do to prevent battery wear. A research paper led by Jihyun Hong at POSTECH and Jongsoon Kim at Sungkyunkwan University on EV (electric vehicle) batteries uncovers a new enemy -- too much discharge. Discharging EV batteries harms them Without getting too deep into the chemistry and physics of battery wear, the study discusses a newly identified mechanism of oxygen loss in layered oxide cathodes used in lithium-ion batteries, specifically during the discharge process at voltages below 3.0V. Because of this additional wear, the study goes on to emphasize the importance of carefully setting DCOVs (discharge cut-off voltages) to slow down degradation and improve battery longevity.
