As smartphones and tablets grow more powerful, they demand more power, draining batteries faster than ever. Unlike basic flip phones that last days on a single charge, today's devices often need nightly top-ups to keep going.
Most modern phones, tablets, and laptops rely on lithium-ion batteries, which are nearing their technological limits. Until breakthroughs arrive, smart care is key to maximizing their lifespan.
Here are expert-recommended strategies to maintain your smartphone and laptop batteries, helping them last longer and alerting you when replacement is due.
Important Notes:
1. These tips focus on battery maintenance and longevity, not daily power-saving optimizations.
2. "Battery" here refers to lithium-ion batteries in smartphones and laptops.

On a Mac, access System Information under the "Hardware" section to view cycle count. Apple rates most MacBooks for 1,000 cycles; older 2010 models may be limited to 500. A full charge-discharge counts as one cycle.
For smartphones, use apps like Battery HD (Android) or Battery Life (iOS/iPad) to monitor capacity. Don't rush replacement until capacity drops to about 20%—though earlier swaps are an option if needed.
Lower screen brightness, enable power-saving modes, and limit GPS reliance. For OS-specific advice, check our guides on Windows, macOS, Android, Linux, and iOS. Above all, store batteries at room temperature and avoid full charges for extended periods.
No battery lasts forever, but proper care can stretch a three-year lifespan further. Regularly monitor health to avoid sudden failures.
