You're charging your phone all wrong: 6 common myths, debunked
↗
A ZDNET article debunks six common smartphone charging myths, arguing that many widely repeated tips are holdovers from nickel-cadmium batteries and do not apply to modern lithium-ion cells.
Engineers building battery management systems or advising on device care need to know which user behaviors actually degrade lithium-ion cells versus which are folklore. The piece confirms that avoiding full charges and extreme temperatures matters, while overnight charging and brand-specific chargers are largely non-issues.

Charging a phone to 100% stresses lithium-ion batteries, which is why manufacturers like Apple, Google, and Samsung offer features to cap charging at 80%.
Running a battery to 0% to 'calibrate' it is a myth from the nickel-cadmium era and does not apply to lithium-ion chemistry.
Charging in extreme cold can cause permanent metallic lithium plating on the anode, even if the device appears to be charging normally.
