To make a new phone last longer between charges, start by lowering screen use and checking which apps are actually draining power. To keep its battery healthier over months and years, limit heat and consider the phone’s built-in charging optimization. These are different goals, and the best settings depend on your phone and how you use it.
Daily battery life and battery lifespan are different
Daily battery life is how long the phone runs before it needs recharging. Battery lifespan is how long its battery lasts before it needs replacement. Lithium-ion batteries chemically age and gradually lose the amount of charge they can hold, so a phone that lasts less time after years of use may have a worn battery rather than a newly changed setting. Apple explains battery aging and these terms.

Make your charge last through the day
Reduce screen power use
- Lower brightness or turn on automatic or adaptive brightness.
- Use a shorter screen timeout so the display turns off sooner when idle.
- Turn off Always-on Display if you do not need it.
Apple and Google recommend brightness adjustments; Google also documents screen timeout and Always-on Display options for Pixel. On Galaxy phones, disabling Always On Display is available through Power saving. Names and paths differ by model and software version. See Apple’s battery guidance, Google’s Pixel instructions, and Samsung’s Galaxy guidance.
Find the apps and conditions using power
Check the built-in battery-use screen before restricting apps. On iPhone, open Settings > Battery and review app usage and background activity. Pixel and Galaxy phones also provide battery-use views; consult the maker’s instructions for the menu names on your model. Limit background activity only when an app is using meaningful power you do not need. Restricting messaging or navigation apps can interfere with updates or other expected behavior. Google recommends leaving app battery use set to “Optimized”; Samsung provides sleep and deep sleep controls for apps you rarely use.

Signal conditions matter, too. A phone using power to search for service in a weak-coverage area may drain faster. Apple lists “No Cell Coverage and Low Signal” in battery usage; Samsung also notes weak or overlapping signal as a factor. If calls are not needed and coverage is poor, Airplane mode is an option, but it disables cellular service.
Use power-saving mode when runtime matters most
When charge is low, a power-saving mode can trade background convenience and some features for longer runtime. iPhone Low Power Mode reduces brightness, optimizes performance, minimizes animations, and limits background activity. Galaxy Power saving restricts background network use and can disable Always On Display. Turn it on when the remaining charge matters more than immediate background updates or display features. Find iPhone’s option under Settings > Battery; Galaxy’s path and available controls vary.

Keep the battery healthier over time
Protect the phone from heat
Avoid leaving or charging an iPhone in hot environments for extended periods. Apple advises against using or charging iPhone at ambient temperatures above 35°C (95°F), because this can permanently reduce battery lifespan. Google says a hot Pixel battery drains faster even when unused, and heat-related drain can damage it. Keep the phone out of direct sun and away from other hot surroundings when practical. Apple’s charging and temperature guidance and Google’s Pixel battery instructions describe these risks.

Choose charging optimization to fit your routine
Charging optimization can reduce how long a phone sits at full charge, but an 80% cap also means less charge available for that day. Use it when battery-health preference suits your routine; disable or adjust it when you need the maximum daily capacity and your phone provides that choice.

- Apple battery performance guidance
If you need to recharge away from an outlet, a compatible USB-C power bank can provide another charging opportunity; it does not increase the phone’s internal battery capacity or health. For Pixel, Google recommends the adapter that came with the phone, noting that other adapters may charge slowly or not at all and could damage the phone or battery. Check compatibility for your specific phone before using a charger or power bank.
