When specs are close, support length decides it — this is what each phone costs per month of safe use.
Category by category
The 15T 5G's screen is the better one — 6.57-inch amoled, 120hz, up to 4000 nits peak.
The P4 5G's MediaTek Dimensity 7400 is simply the faster chip.
The P4 5G has the stronger camera system (2 real rear lenses vs 1).
Battery capacities are close enough not to decide this.
Both phones' support windows end around the same time.
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 P4 5G receive software updates?
It falls under Realme's P4 series policy of 3 major Android OS upgrades and 4 years of security patches. Having launched in August 2025 on Android 15 with realme UI 6.0, it will reach Android 18 and get security updates until roughly August 2029. For a phone that starts near $218, close to four years of patch coverage is unusually good value per month of safe use.
Is the Realme P4 5G worth buying in 2026?
For budget buyers, yes. You get a 144Hz AMOLED, a 7,000mAh battery and about three years of remaining security support for very little money. It is not fast or camera-strong, but as a no-fuss daily phone you can keep supported into 2029, the value per month of safe use is hard to match under $220.
