    1

    Check your battery health

    ~21s
    On iPhone: go to Settings > Battery > Battery Health & Charging. If the Maximum Capacity is below 80%, the battery is a lot worn and replacement will make a noticeable difference. Battery replacement through Apple costs $99 and can make an older phone feel like new. On Android: some phones show battery health in Settings > Battery. Others require a diagnostic app.
    2

    Reduce screen brightness

    ~15s
    The screen is the single biggest battery consumer on most phones. Go to Settings > Display & Brightness (iPhone) or Settings > Display (Android) and lower the brightness. Also turn on Auto-Brightness if available, which adjusts the screen based on lighting conditions and saves power.
    3

    Turn off location services for apps that don't need it

    ~20s
    On iPhone: go to Settings > Privacy & Security > Location Services. Turn off location for any apps that don't genuinely need it. Games, shopping apps, and news apps rarely need your location. Set apps you do want to use location to 'While Using' rather than 'Always.' On Android: Settings > Location > App Permissions.
    4

    Turn off Background App Refresh

    ~18s
    On iPhone: go to Settings > General > Background App Refresh and turn it off entirely, or turn it off for individual apps. This prevents apps from updating their content while you are not using them — a significant battery drain. On Android, go to Settings > Battery > Background usage limits.
    5

    Turn off WiFi and Bluetooth when you are not using them

    ~18s
    If you are out and away from your home WiFi, your phone constantly searches for WiFi networks it recognizes, using battery power. The same is true for Bluetooth. Swipe down to open quick settings and turn off WiFi and Bluetooth when you do not need them.
    6

    Enable Low Power Mode

    ~18s
    On iPhone: go to Settings > Battery and turn on Low Power Mode. This automatically reduces background activity, email fetch frequency, and some visual effects to extend battery life. It is useful when you know you will not be near a charger. On Android, the equivalent is Battery Saver mode under Settings > Battery.
    7

    Consider a battery replacement for older phones

    ~18s
    If your phone is 3+ years old and your battery health is below 80%, a battery replacement is the most cost-effective solution before buying a new phone. Apple, Samsung, and most major manufacturers offer battery replacement services. Prices range from $50–$100. After replacement, the phone usually performs like it did when new.

    A phone battery that drains too fast is one of the most common complaints among smartphone users. It usually comes down to a mix of settings using more power than needed, apps running in the background, or a battery that has aged past its best performance.

    Modern phone batteries are built to hold about 80% of their original capacity after 500 full charge cycles. If you've had your phone for 2–3 years and charge it every day, you've likely gone through 500 or more cycles. That means the battery naturally holds less charge than it once did.

    Before you assume the battery is worn out, check your settings first. Many default settings — location services, background app refresh, screen brightness — are set high out of the box. You can turn them down a lot without changing how you use the phone.
