Common Myths vs. Facts

Myth	Fact
Fully drain before charging.	Li‑ion lasts longer around 20%–80%; avoid frequent 0% or 100% cycles.
Overnight charging always harms the phone.	Modern phones stop current at 100% and use optimized charging.
Any third‑party cable is fine.	Certified cables (USB‑C PD, MFi) ensure correct voltage, reduce heat and risks.
Fast charging ruins batteries.	Certified fast charging (USB‑C PD, Qi2 wireless charging) is designed to protect Li‑ion cells.

Expert Tips to Extend Battery Life

Avoid heat. Keep your phone out of hot cars and direct sun; heat accelerates capacity loss.
Use certified accessories. Prefer original chargers, MFi Lightning, or USB‑C PD cables.
20%–80% charging window. Top up earlier instead of waiting for 0%.
Enable optimization. Turn on “Optimized Charging” / “Adaptive Charging.”
Carry a power bank. A reliable power bank prevents deep discharge while traveling.
Update firmware. System updates often improve battery optimization.
