As we delve into the competitive world of budget smartphones for 2024, battery life remains a pivotal factor for consumers juggling cost and functionality. This year, we turn our focus to notable contenders like the Samsung Galaxy A15, Motorola Moto G24, Xiaomi Redmi A3, Xiaomi Redmi 13C, and Xiaomi Redmi Note 13 4G —all boasting a hefty 5000mAh battery capacity. This means they can all store the same amount of electrical energy. Although they share this spec, actual battery life can vary based on how each phone's hardware and software manage power. So, while they all promise extensive usage times, your experience might differ depending on your chosen smartphone. The best performer will depend on how each brand has fine-tuned its device.

Larger screens, like those on the Redmi 13C (6.74 inches), the Redmi A3 (6.71) and the Redmi Note 13 4G (6.67 inches), generally result in higher battery consumption due to the increased area that needs to be illuminated, especially during activities such as camera and YouTube browsing. In contrast, smaller screens, such as the Galaxy A15 (6.4 inches) and Motorola Moto G24 (6.56 inches), naturally draw less power, contributing to better battery life overall.

Comparing the display technologies, the Redmi Note 13 4G and Samsung Galaxy A15 use AMOLED and Super AMOLED screens, respectively, which are known for their power efficiency when displaying dark content due to their ability to turn off individual pixels. However, these screens can consume more power with bright, colourful visuals. On the other hand, the Redmi 13C, Redmi A3, and Moto G24 use LCD technology, which typically consumes more power overall, especially when displaying bright or white backgrounds.

The Motorola Moto G24's 90Hz refresh rate offers smoother visuals but increases power consumption compared to standard 60Hz screens. Effective optimisation helps mitigate these effects, balancing performance and battery life. For instance, the device can dynamically switch between 90Hz and 60Hz depending on the activity, conserving battery life when higher refresh rates are unnecessary. Additionally, the Moto G24 utilises RAM Boost, which temporarily converts storage into virtual RAM, enhancing multitasking efficiency and reducing strain on the processor, indirectly improving battery performance. The device also incorporates a power-efficient octa-core processor and software optimisations within the Android 14 operating system, such as adaptive battery management and background activity control, further extending battery life. Moreover, the Moto G24 includes Auto Night Vision, an AI-driven feature that optimises camera settings based on ambient lighting conditions to enhance low-light performance without significantly draining the battery. The device also benefits from a clean, almost stock version of Android, avoiding the additional battery drain often caused by heavy manufacturer skins and bloatware.
