• Battery capacity: Every cell phone has a different battery capacity, usually expressed in milliamp hours (mAh). This number tells you the “reserve” of energy available. Knowing this number helps you understand why your phone lasts longer or shorter than other people’s.
• Operating system: Android and iOS have different power saving settings. Familiarize yourself with their sections to discover features that may be useful, such as battery saving mode, automatic brightness settings, or background app restrictions.

Adjust the display settings

The screen is often responsible for the greatest energy consumption in a cell phone, so regulating its use and settings can make a significant difference.

1. Auto brightness: Enabling automatic or adaptive brightness allows the system to adjust the screen illumination based on the ambient light, reducing unnecessary power consumption.
2. Manual brightness: If you prefer, you can manually set a low or medium brightness level that is comfortable for your eyes.
3. Screen timeout: Set the timeout (or “sleep”) for the screen to turn off when you are not interacting with the device. The shorter the time, the less power is wasted.

Control applications and background processes

Background apps can consume a significant percentage of your battery, especially if they update frequently or use location services. Here are some tips to manage this:

1. Limit background usage: On both Android and iOS, you can restrict certain apps from running in the background. This will prevent them from consuming resources and mobile data when you're not actively using them.
2. Disable unnecessary notifications: Every notification you receive on your phone activates the screen and processor, generating additional energy consumption. Filter which applications really deserve your immediate attention and deactivate those that are not essential.
3. Close apps you don't use: Although many modern systems manage memory intelligently, if you notice your battery draining very quickly, it is worth manually closing some applications that you are not using.
4. Control location (GPS): Constant access to your location by many apps drains your battery quickly. Turn off GPS when you don't need it and review the permissions of each app so that they only use your location when absolutely necessary.

Optimize the use of connectivity

Wireless connections such as Wi-Fi, mobile data, Bluetooth or NFC, if left constantly active, can drain the battery in a short time.

1. Use Wi-Fi whenever possible: Wi-Fi typically consumes less power than mobile data. Additionally, downloading apps and updates over Wi-Fi avoids background processes that could negatively impact battery life when using mobile networks.
2. Turn off Bluetooth and NFC if you don't use them: Keeping Bluetooth or NFC on constantly, unnecessarily, means additional energy consumption. Activate them only when you are going to use them, for example, to pair headphones or share files.
3. Airplane mode in low signal areas: When you are in places with poor coverage, your phone will constantly try to reconnect, consuming more power. In these environments, if you don't need data, turning on airplane mode can be useful to preserve battery.

Keep your operating system and applications updated

Developers often release updates to fix performance issues or bugs that can affect battery life. That's why keeping both the operating system and applications up to date is an essential step:

1. System Updates: Check your phone's settings to see if a new version of your operating system is available. These updates bring security improvements and optimizations that can improve energy performance.
2. App updates: Just like the system, apps receive patches and new features that include power-saving optimizations. Download the latest versions to minimize potential battery-draining bugs.

Use power saving mode

Almost all modern smartphones include a “Low Power Mode” option that adjusts settings such as brightness, background refresh, and animations to extend battery life.

1. Manual activation: You can enable it when you see that your battery level is below a limit that you consider critical (for example, 20 %).
2. Automatic programming: Some devices allow you to program this mode to activate automatically when a certain battery percentage is reached. This way, you can avoid the phone turning off unexpectedly.

Take care of your charging habits

The way you charge your phone influences the health and long-term life of your battery. These tips will help you optimize charging cycles:

1. Avoid leaving the battery at 0 % constantly: : Frequently letting it run completely flat can shorten the battery life. It is best to connect it to the charger before it drops below 15 %.
2. Do not exceed 100 % for a long time: Keeping the cell phone connected to the charger for hours after reaching 100 % is not recommended. Although current devices have systems to stop charging, small charge and discharge cycles can occur.
3. Use quality chargers and cables: A genuine or certified charger provides the proper current and protects the integrity of the battery. Generic or low-quality chargers can damage the battery or even pose a safety risk.

Adjust widgets and wallpapers

Interactive widgets on the home screen and live wallpapers may constantly consume resources.

1. Choose static wallpapers: Instead of using moving backgrounds, opt for still images, preferably dark ones if your phone has an OLED or AMOLED screen, since black pixels consume less energy.
2. Moderate the amount of widgets: Use them only if they actually provide important functionality. For example, a weather or calendar widget might be useful, but a social media widget that constantly updates information could drain your battery.

Check the temperature of the phone

Overheating of your cell phone is a symptom of high power consumption and can also damage the battery in the long run.

1. Avoid using your phone under intense sunlight: High temperatures accelerate the chemical degradation of the battery.
2. Close demanding applications: Heavy gaming or video editing consumes a lot of power and generates heat. If you notice your phone getting excessively hot, give them a break.
3. Use suitable covers: Some thick cases retain heat and cause the internal temperature to rise. If your phone gets too hot, remove the case for a while to ventilate it.

Apps that help manage battery consumption

There are apps designed to monitor and optimize battery usage. These tools typically provide detailed reports on each app's power consumption, estimate how much usage time is left before recharging, and suggest specific actions to save battery life. Here are some popular options:

1. AccuBattery (Android)
   • Measures battery consumption in real time and estimates battery health.
   • Provides clear statistics to understand which apps consume the most energy.
2. Battery Guru (Android)
   • Provides battery usage statistics, charging reminders, and optimization tips.
   • It has alarms to warn when the battery reaches certain levels.
3. Greenify (Android)
   • Allows you to “hibernate” applications that are not in use, preventing them from consuming energy in the background.
   • Very useful for devices with many active processes.
4. Battery Life (iOS)
   • Provides data on the actual capacity of the battery, providing alerts when it detects increased wear.
   • It informs how many approximate hours of use are left depending on the activity (internet, calls, music, etc.).
5. iOS Settings – Battery (iOS)
   • On iPhones, under Settings > Battery you will find a detailed panel.
   • It is not an external app, but it is very useful, as it analyzes the consumption of each application.

These apps are usually free or have versions with additional features. They usually focus on improving the user experience and extending the phone's battery life with effective strategies. However, it is worth remembering that they should not become another factor of excessive energy consumption: if you install a battery management app, check if it is really optimizing your resources.

The importance of regular maintenance

Although modern batteries require less and less maintenance, there are maintenance aspects that should not be overlooked:

1. Port cleaning: The charging and headphone ports can accumulate dust and lint, making it difficult to connect and therefore charge. Clean them carefully using compressed air or a soft object.
2. Malware protection: By downloading unreliable apps, your phone can be affected by malicious programs that secretly consume data and energy. Use official stores and, if necessary, a reliable antivirus.
3. Occasional reboot: Turning your cell phone on and off from time to time helps free up memory and close unnecessary processes, which can have a positive effect on the battery.

Towards a more conscious and efficient use

Optimizing your cell phone's battery also involves changing your habits. Reducing the amount of time you use it when it's not essential or turning off unnecessary notifications helps prevent excessive energy consumption. Also, storing your device in a cool place and using certified charging accessories are simple steps that, in the long term, extend the battery's useful life.

As technology advances, operating systems become smarter at managing resources, and batteries increase their capacity. However, the user always has the final say in how the device is used. If you pay attention to the details mentioned above, you will see how you can extend those precious hours of autonomy for your smartphone, making it always available when you need it most.
