Many smartphone users complain about battery draining quickly, but what they don’t realize is that today’s devices — both **Android** and **iOS** — have a number of in-built tools designed to combat this issue. These often overlooked or “hidden” settings can make a big difference while still having little impact on everyday use.
**Turn on battery saver or low power mode**
Both platforms offer a special power-saving mode. On Android it’s called **Battery Saver** (or Extreme Battery Saver on Pixel phones); On iPhone this is called **Low Power Mode**. When turned on, these features automatically dim the screen, limit background activity, slow down performance for non-essential tasks, and pause visual effects. Experts confirm that this can extend the battery life by several hours, especially when the battery drops below 20–30%. You can turn it on manually or set it to turn on automatically at a certain percentage.
**Limit the activities of apps running in the background**
Apps that refresh data in the background silently drain your battery. On iOS, go to **Settings > General > Background App Refresh** and set it to “Wi-Fi only” or “Off” for non-essential apps. On Android, limit background usage by going to **Settings > Apps > (App) > Battery**. This reduces unnecessary data syncing, notifications, and frequent screen restarts.
**Use dark mode on OLED/AMOLED screens**
Dark Mode is only helpful in saving battery on **OLED** or **AMOLED** displays (these displays are commonly found in today’s flagship phones like the new iPhone, Samsung Galaxy, and Google Pixel). Pixels that are completely black turn off completely, which reduces power consumption — savings of up to 30–40% can occur at high brightness, although savings are smaller at medium brightness. On an LCD screen, this is of little benefit.
**Some more easy solutions**
– Turn off **Always-On Display** (AOD) when not needed.
– For non-essential apps, limit **Location Services** to “While Using the App” only.
– Turn on **Adaptive Battery** (Android); It uses AI to learn your habits and limit battery-hungry, less-used apps. Most users ignore these features because they are hidden in settings or activate only when the battery is low. Tech experts recommend checking these in advance, especially before trips or long days. These simple changes can significantly reduce battery drain without affecting the core functionality of your smartphone’s existing tools. Regularly check the battery section of your device for usage information and change settings as needed.
