How does screen size affect battery life?

Diagonal and screen technology are directly related to battery consumption.In the case of Xiaomi Mi A3 super AMOLED and HD+-permission gives several advantages:

1. Low energy consumption in dark topics. AMOLED-The matrix does not illuminate black pixels, so when using dark wallpaper or mode AMOLED Black battery consumption is reduced by 15-20%.
2. Less pixels is less load on the GPU. The 1560×720 resolution requires less resources for rendering than Full HD, which prolongs the time without recharging.
3. Optimizing Android One: A clean Android without a MIUI shell consumes less power on background processes.

According to the results of GSMArena tests, the Mi A3 with a battery capacity of 4030 mAh shows the following results of autonomy:

• 📞 Conversation: Up to 30 hours (3G)
• 🌐 Web surfing: up to 12 hours (Wi-Fi)
• 🎮 Games: up to 6-7 hours (PUBG Mobile on Medium Settings)
• 🎥 Video: Up to 16 hours (YouTube, average brightness)

By comparison, the Redmi Note 8 Pro with a 6.53" screen and a 4,500 mAh battery in the same tests only performs 10-15% better despite its larger capacity, confirming that AMOLED + HD+ is an energy-efficient solution.
