Small adjustments to charging timing, plus one setting already built into the device, are enough to keep a phone battery healthier for far longer, per CNET's guidance.
The single most common charging routine — leaving a phone plugged in until it reaches a full 100% — is precisely the behavior CNET's new battery-health guidance tells users to abandon.
The outlet's advice amounts to a short list of behavioral corrections rather than any purchase. A few adjustments to when a phone is charged, and how far each charge is allowed to run, can meaningfully slow the wear that accumulates on a battery over months and years of daily use. Chief among them: stop taking every charge to a full 100%. The remainder of the guidance centers on timing — restructuring the charging window so the battery spends less of its life at the top of its range.
One detail stands out. CNET points to a single setting already built into the phone that carries much of the load. No third-party app, accessory or replacement component is required — the device's own software can enforce the healthier charging pattern once enabled. That lowers the barrier considerably for anyone who finds manual charging discipline impractical.
The broader implication concerns device lifespan. A phone's battery is the component most exposed to daily degradation, and CNET's framing suggests battery health is not fixed at manufacture — it is a function of habits, and modest ones at that. The payoff for changing them is a battery that stays healthier for longer, pushing back the point at which fading endurance would otherwise force a device into retirement.
The complete list of adjustments, and the exact setting involved, is laid out in CNET's guide.
