Frequently asked

How water resistant is the Realme P3 Ultra?

It carries IP68 and IP69 ratings, making it dust-tight and resistant to immersion as well as high-pressure water jets.

What is the battery and charging on the P3 Ultra?

It packs a 6000mAh battery with 80W wired charging (full charge in about 47 minutes) plus 5W reverse charging.

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.
