Category by category
The 15T 5G's screen is the better one — 6.57-inch amoled, 120hz, up to 4000 nits peak.
The P3 Pro 5G's Qualcomm Snapdragon 7s Gen 3 (4nm) is simply the faster chip.
Camera systems are comparable on paper — pick by sample photos.
Battery capacities are close enough not to decide this.
The 15T 5G is supported until Sep 2029 — 6 months longer than the P3 Pro 5G.
Pound for pound, these two are equally good deals.
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 P3 Pro 5G get software updates?
Realme promises the P3 Pro 5G 3 Android OS upgrades and 4 years of security patches. From its February 25, 2025 release, that means security support runs through about February 2029.
Does the Realme P3 Pro 5G have NFC?
No. The P3 Pro 5G omits NFC, so it does not support tap-to-pay contactless payments.
