Battery Saving Apps — Your Settings App is the Only Tool You Need

Battery-saver apps usually can’t do what they claim because iOS controls the settings that actually affect battery life. Many of these apps end up being glorified tip lists with toggles you could change yourself, with a few ads thrown in to make some money off of you.

Instead, use what iOS already provides. Low Power Mode is the real battery saver, because it adjusts background behavior in a way third-party apps can’t. And Battery Health gives you the information about your battery that you actually need. If your battery health is degraded, no app can fix that. What you need is better charging habits or, eventually, a battery replacement.

Last but not least, you can also use Limit Charge or Optimized Battery Charging. Limit Charge debuted on the iPhone 15 and lets you cap your charge at a specific percentage — a lifesaver for battery longevity — while Optimized Battery Charging learns your charging patterns so it can slow down charging at the 80% mark and keep your battery healthy over time.

If you want your iPhone to feel better day-to-day, knowing your battery health is far more valuable than any battery app promising magic.
