Realme U1 — Full Specifications, Features & Price in Pakistan

The Realme U1 is a piece of smartphone history: launched in November 2018, it was the first phone ever to ship with MediaTek's Helio P70 chip, and it kicked off Realme's selfie-focused U-series with a 25MP Sony front camera. Eight years on, it is long discontinued — any unit in Pakistan today is a used device sold on the second-hand market. This guide covers its verified specifications, sets honest expectations for a 2018 phone in 2026, and explains exactly what to check before buying one used.

Key Specifications at a Glance

Design and Build Quality

The U1 follows the late-2018 design language: a 6.3-inch display with a small dewdrop notch, slim side bezels, and a laminated polycarbonate back with a light-pillar pattern. A rear-mounted fingerprint sensor sits below the dual camera. Build is plastic throughout — normal for its class and era. On a used unit, check the back for deep scratches, test the rear fingerprint sensor (these wear with age), and inspect the micro-USB port for looseness, since micro-USB connectors degrade faster than USB-C.

Display Features

The 6.3-inch IPS LCD runs at 1080 x 2340 (Full HD+), protected by Gorilla Glass 3, with a claimed 90.8% screen-to-body ratio. For 2018 it was a crisp, bright panel. In 2026 terms: no high refresh rate (60Hz), no AMOLED blacks, and modest brightness by modern standards — fine for calls, WhatsApp, and video, but visibly dated next to any current phone.

Processor and Performance

The Helio P70 (12nm, up to 2.1GHz) with Mali-G72 MP3 graphics was a strong mid-range chip in 2018 and the U1 was its debut device. Today, be realistic: it handles calls, messaging, light social apps, and video playback, but modern heavy apps and games will strain it, and 3GB RAM on the base variant is tight for 2026-era Android apps. Buy this as a basic secondary phone, not a daily driver for demanding use.

RAM and Storage

Two variants existed: 3GB + 32GB and 4GB + 64GB. The saving grace is the dedicated microSD slot (up to 256GB) alongside dual SIMs — no hybrid-slot compromise. If buying used, strongly prefer the 4GB + 64GB variant; 32GB of internal storage fills up fast with modern app sizes, and the system partition on an Android 8.1 device leaves you less usable space than the headline number suggests.

Camera Features

The U1's claim to fame was its 25MP Sony IMX576 front camera (f/2.0) — marketed as "India's SelfiePro" at launch, with AI beautification, bokeh, and HDR. The rear is a modest 13MP (f/2.2) + 2MP depth combo. In 2026, expect decent daylight selfies and average rear shots; low-light performance was already flagged as weak in contemporary reviews, and there is no 4K video recording or video stabilisation. Treat the cameras as functional, not competitive.

Battery and Charging

A 3,500mAh battery with 10W (5V/2A) charging — slow by any modern standard, with no fast charging to speak of. More importantly, any U1 battery in 2026 is at least seven years old. Lithium batteries degrade with age regardless of use, so expect reduced capacity: ask the seller about battery health, and budget for the possibility that a full day of use is no longer realistic. Replacement batteries for a 2018 model may be hard to source.

Software and Updates

The U1 launched on Android 8.1 Oreo with ColorOS 5.2 and received no meaningful long-term update support — this is a hard stop for security. In 2026, an Android 8.1 device cannot run some current banking and payment apps, which increasingly require newer Android versions, and it carries unpatched vulnerabilities. Do not use it as your primary phone for banking, email, or anything sensitive. This is the single biggest caveat of buying this model today.

Connectivity and Additional Features

Dual 4G VoLTE, Wi-Fi 802.11ac, Bluetooth 4.2, GPS, micro-USB, and a 3.5mm headphone jack. There is no 5G, no NFC (not confirmed for this model), and no USB-C. Bluetooth 4.2 works with modern earbuds but lacks the range and stability improvements of newer versions. Check that both SIM slots and the microSD slot read correctly on a used unit.

Variants, Colours and Availability

Verified variants: 3GB + 32GB and 4GB + 64GB (India launch pricing was INR 11,999 and INR 14,999 respectively). The U1 was an India-focused launch and is long discontinued globally — there is no new stock anywhere. Every unit in Pakistan is used, and spare parts are scarce. Availability is whatever the second-hand market holds on any given week.

Price in Pakistan and PTA Information

Zohaan Mobile Gallery lists the Realme U1 at Rs. 28,500 (store product page, verified 2026-10-11). At this price, be clear-eyed: you are paying for a 2018 used phone with an obsolete OS — compare it against newer used options in the same budget before deciding, and confirm the current asking price with the store since used prices move with condition and availability.

PTA: PTA status is per device and IMEI. A phone this old may be PTA-registered from years of use, or may not be — never assume. SMS the IMEI to 8484 and confirm "Compliant" status before paying. How to check PTA approval.

Main Advantages and Limitations

Advantages:

• 25MP Sony front camera — still decent for video calls
• Dedicated microSD slot alongside dual SIM
• Headphone jack and simple, light software
• Low used price for a basic backup phone

Limitations:

• Android 8.1 with no security updates — unsuitable for banking/sensitive use
• Seven-plus-year-old battery with 10W slow charging
• Weak low-light cameras; no 4K or stabilisation
• micro-USB port; no 5G, no NFC
• Spare parts increasingly hard to find

Who Should Consider This Phone?

Good fit: someone needing the cheapest possible functional backup phone — for calls, WhatsApp, and hotspot duty — who understands its limits and will not put sensitive accounts on it.

Look elsewhere if: this is meant to be a primary phone, you need banking apps, or you want a camera you can rely on — in that case browse newer used options in the Realme collection or all mobiles.

Frequently Asked Questions

What is the Realme U1 price in Pakistan?

Rs. 28,500 is the store-listed used price at Zohaan Mobile Gallery (verified 2026-10-11). Used prices depend on condition — confirm the current figure before buying.

When was the Realme U1 launched?

28 November 2018 in India. It was the first phone with the MediaTek Helio P70 and launched Realme's selfie-focused U-series.

Can it run modern apps in 2026?

Basic apps, yes; but Android 8.1 blocks some current banking and payment apps, and 3GB RAM struggles with heavy multitasking. Verify your must-have apps work before buying.

Is it safe for banking?

No — an Android 8.1 device with no security updates since 2018 should not be used for banking, email, or sensitive accounts.

What are its RAM and storage options?

3GB + 32GB or 4GB + 64GB, with a dedicated microSD slot (up to 256GB). Prefer the 4GB + 64GB variant.

How is the battery after all these years?

Any original battery is 7+ years old and will hold less than its 3,500mAh rating. Ask for a battery health check and expect reduced endurance; replacements are hard to source.

Is it PTA approved?

PTA status is per device. SMS the IMEI to 8484 and confirm "Compliant" status before paying — never assume.

Should I buy it as my main phone?

Honestly, no. It works as a cheap backup or a first phone for basic use, but the obsolete software makes it a poor primary device in 2026.

Final Verdict

The Realme U1 is a nostalgia buy with a practical niche: a working backup phone with a decent selfie camera and expandable storage at a low price. Its honest reality is an obsolete, insecure operating system and an ageing battery. Buy it only with eyes open — verify the IMEI, test the battery and ports, confirm the price, and keep sensitive accounts off it.
