Reducing screen brightness is an easy way to extend your smartphone’s battery life. By lowering brightness or enabling adaptive brightness settings, you can significantly reduce the power consumption of your display.

The Shift to 4G and 5G

The shift from 3G to 4G networks revolutionized mobile internet speeds, but it also significantly impacted battery life. With faster data speeds, users began streaming videos, downloading large files, and using real-time applications more frequently. This led to an increased drain on the battery. Now, with the evolution of smartphones incorporating 5G, the demands on batteries are even greater. While 5G technology provides unparalleled speed and low latency, it also consumes more energy, particularly when constantly searching for a 5G signal in areas with poor coverage.

Tip: Use Wi-Fi When Possible

Switching to Wi-Fi can save battery life, as cellular data, especially 5G, can drain the battery faster. By connecting to Wi-Fi whenever available, you can reduce energy consumption significantly.

Power-Hungry Processors and Advanced Features

The evolution of smartphone processors has led to impressive performance, but this comes at the cost of increased power usage. Flagship smartphones are now equipped with multi-core processors that can handle heavy multitasking, gaming, and artificial intelligence tasks. These advanced chipsets, while offering top-tier performance, also require more power to operate efficiently.

Modern smartphones also come with additional power-draining features such as biometric authentication (face recognition, fingerprint sensors), high refresh rate displays (90Hz or 120Hz), and augmented reality (AR) capabilities. All these features contribute to faster battery depletion.

Tip: Disable Unnecessary Features

If you’re not using certain features like Bluetooth, GPS, or high refresh rate settings, consider turning them off. Disabling these options can help conserve battery life for more critical tasks.

Introduction of Fast Charging and Its Benefits

As battery life became a major issue for consumers, manufacturers focused on the evolution of smartphone charging technologies. Fast charging became a key solution to combat the inconvenience of short battery life. Modern fast-charging technologies allow users to charge their smartphones to 50% or even 70% in as little as 30 minutes. This evolution drastically reduced the amount of time users had to wait to get back to full power, making the need for long-lasting batteries somewhat less critical.

Although fast charging helps reduce downtime, it can also affect long-term battery health. Excessive fast charging may generate heat, which, over time, can degrade battery performance.

Tip: Use Fast Charging Sparingly

While fast charging is convenient, using it too often can shorten your battery’s lifespan. It’s best to use it only when necessary and opt for regular charging overnight or when you have more time.

Software Optimizations and Battery Management

The evolution of smartphones has not only been hardware-focused but also centered around software optimizations to extend battery life. Operating systems like Android and iOS have introduced a variety of features that help manage battery consumption more efficiently. For example, power-saving modes, which limit background processes and reduce performance, can extend battery life in critical situations.

App developers have also worked to make their software more energy-efficient, minimizing background activity and reducing unnecessary refreshes that can drain the battery.

Tip: Enable Power-Saving Mode

When you’re running low on battery, enabling power-saving mode can help stretch your remaining battery life by limiting background processes, reducing performance, and turning off unneeded connectivity options.

Itel’s Commitment to Battery Efficiency
