Start by checking what is using power, then make small changes to screen use and optional high-drain activities. Keep built-in adaptive optimization on, and use Battery Saver or Power saving only when you need extra reserve.
Menu names and available controls vary by phone, manufacturer and software version. The steps below are grounded in Google Android, Pixel and Samsung Galaxy guidance; they are not universal iPhone instructions.
1. Find what is using the battery before restricting anything
Open your phone’s Battery settings and review recent usage. On some Galaxy phones, Samsung’s Device care tools also show apps with high battery use. The exact path and labels depend on the model and software version.
Look for an app or activity using more power than you would expect for how much you used it. If one app stands out, consider changing only that app’s background behavior rather than disabling services across the phone. Background limits can delay notifications, syncing or other work.

2. Make the screen use less power
Try these low-impact adjustments first. Set brightness to a comfortable lower level, and shorten the time before the screen turns off when idle. You do not need to make the screen difficult to read to save power.

- Lower brightness: A bright display can increase consumption, especially during extended screen-on use.
- Shorten screen timeout: This reduces the time the display stays lit after you stop interacting with the phone.
- Consider what you are doing on-screen: Prolonged video, streaming, high-resolution content and graphics-heavy games can use more power than brief checks or messaging.
3. Pause optional high-drain activities
Some activities draw more power when used for long periods. Google lists navigation, extended GPS use, hotspot tethering, streaming, video and graphics-heavy games among examples to avoid when trying to extend a low charge. Samsung also identifies location services, high-performance apps, high-resolution streaming and weak or overlapping signal as possible contributors.
- Turn off your hotspot when no other device needs the connection.
- Stop navigation or location-intensive use when you are finished. Do not disable location globally if maps, safety features or another service you rely on needs it.
- When a charge is running low, consider postponing long gaming, video or streaming sessions.
- If you are in a weak-signal area, expect the phone’s power use to vary; Samsung notes that weak or overlapping signal can contribute to higher consumption.
4. Keep adaptive battery optimization on for everyday use
On supported Pixel phones, Adaptive Battery learns how you use apps and limits less-used apps while the phone is idle. Google’s Pixel guidance recommends keeping Adaptive Battery and battery optimization on. The trade-off is that optimization may reduce performance or delay notifications from affected apps.

Other Android manufacturers may use different names, settings or behavior. If you decide to restrict an individual app, do so because its background use is worth the possible delay to alerts or syncing—not as a blanket measure for every app.
5. Use Battery Saver or Power saving when you need a reserve
Low-power modes are useful when you need the remaining charge to last longer, but they achieve that partly by limiting activity. Android’s Battery Saver and Samsung’s Power saving can restrict background activity or data and may affect some features. The exact effects depend on the phone and its settings.

Google Android Help warns: “Your battery drains much faster when it’s hot, even when not in use.” Heat can also damage the battery, so avoid leaving a hot phone in conditions that make it hotter. Google also says you do not need to repeatedly run a battery from full to zero to teach it its capacity.

Charging optimization is a different concern from stretching the charge you have today. On supported Pixel models, charging optimization can reduce time spent fully charged or cap charging. Those controls concern long-term battery health, not an immediate extension of the current charge.
7. If the drain is sudden or continues, investigate it
Pixel Phone Help says, “It’s normal for your Pixel battery to drain a little more than usual after a software update.” A temporary increase can happen while the phone optimizes software. Check usage again after a few days; if the drain remains unusual, review battery use and follow support guidance for your specific device rather than turning off features at random.
For a non-Pixel Android phone, use the manufacturer’s device-specific support because menus and troubleshooting can differ. The Android, Pixel and Samsung guidance cited here does not establish iPhone-specific menu paths.
