Apple's 80% Charging Limit for iPhone
Apple's introduced a setting to limit iPhone charging to 80% aiming to extend battery lifespan. However, the results from a year-long personal test show only a slight battery capacity improvement. The testing user reported occasional inconveniences and expressed doubt on the long-term benefits, arguing that a charge limit of 90% might be more suitable for average users. The overall long-term effects of adhering to this charging strategy remain unclear.
