Smartphone Batteries

Your phone's lithium battery can swell and rupture when overcharged or exposed to heat. Avoid charging your phone in direct sunlight or high-temperature environments, and use manufacturer-approved chargers in well-ventilated areas.
Most modern smartphones fully charge in 30-90 minutes with fast charging, while standard charging may take 2-4 hours depending on the device and charger.
Remove phone case only if device becomes unusually warm or if manufacturer recommends it. This reduces battery temperature and can help extend battery life.
