Frequently asked

When does the Realme 15T 5G stop getting updates?

As part of Realme's 15 series, the 15T is covered by the policy of 3 major Android OS upgrades and 4 years of security patches. Launched in September 2025 on Android 15 with realme UI 6.0, it will reach Android 18 and receive security patches until around September 2029, giving a buyer in 2026 roughly three more years of safe, patched use.

How does the Realme 15T fit a 7,000mAh battery in such a thin body?

Realme uses a high-density silicon-based Titan cell, which stores more capacity in less space than a conventional lithium battery. The result is a 7,000mAh phone that is just 7.79mm thick and about 181g - lighter than many phones with smaller batteries - while still charging at up to 80W with the bundled adapter.

How long will the Realme P4 Pro 5G get updates?

Realme officially commits the P4 series to 3 major Android OS upgrades and 4 years of security patches. Launched in August 2025 on Android 15 with realme UI 6.0, the P4 Pro will move up to Android 18 and receive security patches until about August 2029. That roughly four-year window is strong at this price and a key reason it is a sensible long-term budget keeper.

Is the Realme P4 Pro 5G worth buying in 2026?

Yes for value seekers: at around $294 you get a curved 144Hz AMOLED, a 7,000mAh battery, Snapdragon 7 Gen 4 performance and about three years of remaining security support. The main compromises are the downgraded IP66 rating and the basic secondary camera, so anyone who dunks their phone or wants zoom should weigh those carefully.
