Infinix Hot 7 Pro vs Tecno Spark 3 Pro

The Infinix Hot 7 Pro and Tecno Spark 3 Pro both came out in 2019, and neither is made or sold new any more. Both run Android 9 Pie, which stopped getting Google security patches years ago, so you should not use either one as your main phone in November 2026. In the same price band today, Infinix sells the Hot 70 series (global launch 25 May 2026) and Tecno sells the Spark 50 series (from April 2026). If you are buying now, look for a phone that still gets OS upgrades, a 5,000 to 7,000 mAh battery and at least 4GB of RAM. The comparison below is still useful if you own one of these phones or are looking at a used one.

Which one should you go for, and which is the better phone?

Infinix and Tecno are two of the biggest phone brands in Nigeria. Both belong to Transsion Holdings, and both sell mostly in the budget segment.

So which one should you pick, the Hot 7 Pro or the Spark 3 Pro?

• The Infinix Hot 7 Pro and the Tecno Spark 3 Pro both have a tall screen of about 6.2 inches, so screen size does not separate them.
• Both shipped with Android 9.0 (Pie) under each brand’s own skin: XOS 5.0 Honeybee on the Infinix and HiOS on the Tecno. The basic software experience is very similar.
• The Infinix has the stronger hardware overall, as the sections below show.

Infinix Hot 7 Pro vs Tecno Spark 3 Pro: introduction

Both phones launched in 2019. GSMArena lists March 2019 for the Hot 7 Pro and April 2019 for the Spark 3 Pro. In India, Infinix launched the Hot 7 Pro on 10 June 2019 at Rs 9,999 for the 6GB/64GB version, and Flipkart started selling it on 17 June 2019.

The Hot 7 Pro had some unusual features for its price, most of all two cameras on the front.

The Spark 3 Pro was a solid budget phone too, with a big screen and a large battery for its class.

If you can’t decide between them, the sections below compare them one area at a time.

Infinix Hot 7 Pro vs Tecno Spark 3 Pro: comparison

Short answer: the two phones look and feel alike, but the Hot 7 Pro wins on chip, RAM, selfie camera and battery.

Body

The body and design are the first things you notice about a phone.

Both phones aim for a premium look, and both put the fingerprint sensor on the back.

Both have a wide notch at the top of the screen, and the two notches are about the same size.

Their dimensions are almost the same, too. The Hot 7 Pro is about 156 x 75 mm and the Spark 3 Pro is about 156.5 x 76 mm, so you will barely feel the difference in your hand.

Both use IPS LCD screens, not OLED.

In short: same design ideas, nearly the same size, same screen technology.

Screen and resolution

Screen size is a tie, just like the body.

Both the Hot 7 Pro and the Spark 3 Pro have a screen of about 6.2 inches. Infinix’s own India launch material called it 6.19 inches.

Resolution is close as well. Both are HD+ panels. Listings give the Infinix either 720 x 1500 or 720 x 1520, and most databases give the Tecno 720 x 1500. At this screen size you will not see the difference. (An earlier version of this comparison said the Tecno had the higher resolution, but the spec listings don’t support that.)

So there is still no clear winner at this point.

Operating system (OS)

The OS matters on any phone. It is the biggest difference between an iPhone and an Android phone, so it can make or break a purchase.

Here, both phones run the same version: Android 9.0 Pie from Google.

When these phones launched in early 2019, Pie (released in August 2018) was the newest Android release, and Android 10 followed in September 2019. Today it is very old. Android 9 no longer gets Google security patches, and neither phone got a major Android upgrade that would change that. This is the main reason neither phone is a safe daily driver in 2026.

System on chip (SoC)

This is where the gap between the two phones starts to show.

The SoC, the main chip inside the phone, handles processing speed and graphics. A weak chip makes the phone feel slow and frustrating.

The Infinix Hot 7 Pro uses the MediaTek Helio P22 (MT6762). The Tecno Spark 3 Pro uses the cheaper MediaTek Helio A22 (MT6761). Both chips are built on a 12 nm process, use Cortex-A53 cores running at up to 2.0 GHz and have the same PowerVR GE8320 GPU. Their performance specs differ in one key way: core count.

The Helio P22 has eight cores (octa-core) and the Helio A22 has four (quad-core). For single tasks they feel similar. With several apps open, or in heavier games, the eight cores give the Infinix a real advantage.

Storage and RAM

Storage is a tie. Both models sold in Nigeria had 32GB, with a microSD slot for more.

RAM is where they differ. The common Nigerian Hot 7 Pro had 3GB, against 2GB in the Spark 3 Pro. Infinix also made a 2GB version, and a 6GB/64GB version was sold in India.

With more RAM, the Hot 7 Pro takes the lead in this round.

Camera

Camera is one of the most hyped features on any phone, for makers and buyers alike.

The Hot 7 Pro wins here, thanks to its front camera.

On the back, the two phones are even: each has a 13MP main camera with a 2MP depth sensor.

On the front, the Hot 7 Pro has a 13MP selfie camera plus a 2MP depth sensor. The Spark 3 Pro has one 8MP selfie camera. That gives the Infinix a sharper selfie sensor and depth data for portrait-style selfies. (An earlier version of this comparison said the Infinix also had a better main camera on the back. It didn’t: both rear cameras are 13MP + 2MP.)

Battery

Battery life also depends on the screen. A phone with an OLED panel, or a smaller or lower-resolution screen, would use power differently.

These two phones have similar LCD screens of the same size and resolution, so you can compare their batteries directly.

The Hot 7 Pro wins again, with 4,000 mAh against 3,500 mAh in the Spark 3 Pro.

Infinix Hot 7 Pro vs Tecno Spark 3 Pro: verdict

Based on the comparison above, the Infinix Hot 7 Pro beats the Tecno Spark 3 Pro on processor (eight cores against four), RAM, selfie camera and battery. The two tie on screen, storage, rear camera and software.

In 2019, the Hot 7 Pro was the better buy if you could afford the extra few thousand naira. The Spark 3 Pro made sense if you wanted the lowest price.

In 2026, neither phone is worth buying new, and even a used one is only a stopgap. Both are stuck on unsupported Android 9, and any original battery will be about seven years old. If you already have one, the Hot 7 Pro will cope better with today’s apps. A current entry-level model from either brand will still beat both by a wide margin.

Infinix Hot 7 Pro vs Tecno Spark 3 Pro: prices and availability

These are the 2019 Nigerian launch-era prices, kept as a record. Both phones are discontinued, and any listing today will be old stock or a used unit.

Infinix Hot 7 Pro

• Price in 2019: ₦45,000 to ₦47,000
• Where it was sold: Jumia and other Nigerian retailers

Tecno Spark 3 Pro

• Price in 2019: ₦40,000 to ₦45,000
• Where it was sold: Jumia and other Nigerian retailers

What to buy instead in 2026

The current replacements are the Infinix Hot 70 and the Tecno Spark 50 series. Each one has roughly double the battery of these 2019 phones, plus a 120 Hz screen.

Tecno also sells the standard Spark 50. In Nigeria it launched with a 6,700 mAh battery, a 120 Hz screen and a 50MP main camera. The Spark 50 4G uses a Helio G81 chip and, in some markets, a 7,000 mAh battery. If you want 5G, look at the Spark 50 5G, which uses a Dimensity 6400 chip.

Before you buy, check the promised software support. Infinix’s three-OS-upgrade promise for the Hot 70 is the most important difference between that phone and the Hot 7 Pro. Also check the price with official stores or big retailers such as Jumia and Konga, because unofficial price listings for these models vary a lot.

FAQ

Is the Infinix Hot 7 Pro still sold or supported?

No. Infinix stopped making the Hot 7 Pro years ago, and it runs Android 9 Pie, which no longer gets Google security patches. Any unit for sale now is old stock or used. The current Infinix model in this range is the Hot 70.

Which is faster, the Hot 7 Pro or the Spark 3 Pro?

The Hot 7 Pro. Its Helio P22 has eight cores against four in the Spark 3 Pro’s Helio A22, even though both run at up to 2.0 GHz and share the same GPU. The Hot 7 Pro’s extra RAM (3GB against 2GB on the Nigerian models) also helps when you switch between apps.

Does the Tecno Spark 3 Pro have a better camera than the Infinix Hot 7 Pro?

No. On the back the two are equal, each with a 13MP main camera and a 2MP depth sensor. On the front, the Hot 7 Pro has a 13MP + 2MP dual selfie setup, while the Spark 3 Pro has a single 8MP camera, so selfies favour the Infinix.

What replaced the Tecno Spark 3 Pro?

Tecno’s Spark line has gone through many generations since 2019. In 2026 it is the Spark 50 series, which includes the Spark 50, Spark 50 4G, Spark 50 5G and Spark 50 Pro. These have far bigger batteries, 120 Hz screens and much stronger chips than the Spark 3 Pro.

Is a used Hot 7 Pro or Spark 3 Pro worth buying in 2026?

Only as a cheap backup or a phone for a child, and only if you accept the security risk of old, unpatched software. The original battery will have lost a lot of its capacity after about seven years. For everyday banking and messaging, a new entry-level phone that still gets updates is the safer choice.

How much did these phones cost at launch in Nigeria?

In 2019, the Hot 7 Pro sold for about ₦45,000 to ₦47,000, and the Spark 3 Pro for about ₦40,000 to ₦45,000. In India, Infinix launched the 6GB/64GB Hot 7 Pro at Rs 9,999.
