Infinix Hot 4 Pro

The Infinix Hot 4 Pro (August 2017) is an affordable 5.5″ HD phone with a 4000mAh battery—excellent for long runtimes and basic apps, but underpowered for modern 3D games and won’t receive long-term Android/security or feature updates.

Why you should read this guide

Search results for “Infinix Hot 4 Pro” typically return short spec lists or scattered user blurbs. Those are fine if you only need one fact, but most buyers want more: actual battery behaviour, camera reliability in daylight and low light, whether certain apps run well, and whether the device is still a reasonable buy today.

This guide gives you:

• Clear, real-world expectations for battery, camera, and everyday performance.
• Practical how-to tips to keep the phone fast and extend battery life.
• A buyer’s checklist tailored for used and refurbished markets.

I’ve written this in plain English and bolded important keywords so that readers (even a 15-year-old) can scan for the essentials.

Design, build, and display

Design & feel

The Hot 4 Pro is a classic 2017 budget device: plastic unibody, textured back, and a design that prioritizes grip and durability over premium materials. The textured rear hides scratches and fingerprints well and helps grip, which is useful if you want a phone you can use one-handed.

Short takeaways:

• Not premium, but solid and practical.
• Textured back helps with long-term wear.
• Buttons and ports are standard for the era — nothing fancy but reliable.

Display

A 5.5″ HD panel (720p) is the defining screen spec. At this size, the pixel density is serviceable for social media, reading, and video at 720p. Compared to modern Full HD (1080p) displays, you will notice softer edges and less detail in small text or high-detail images.

Practical display tips:

• Use a matte screen protector to reduce glare outdoors.
• Increase system font size slightly for long reading sessions.
• Use browser “reader” mode for long articles to improve readability.
• Lower brightness when indoors; the battery and panel benefit.

Short verdict: Comfortable and practical. If you value battery life over Pixel Density, the Hot 4 Pro’s display is acceptable.

Performance

SoC & memory

The MediaTek MT6737 with 2–3 GB RAM is an entry-level platform designed to be cheap and power-efficient. It was never intended for heavy multitasking or intensive 3D gaming.

Real-world expectations

• Good for: Calls, SMS, WhatsApp, light browsing, Facebook, Instagram, and YouTube at 720p.
• Okay for: Switching between a couple of apps, light photo editing, and social media posting.
• Poor for: Heavy multitasking, modern 3D titles (PUBG / CODM), and intense background workloads.

Gaming notes

Casual games (Temple Run, Subway Surfers) run fine. For heavier titles:

• Set graphics to the lowest.
• Close background apps.
• Limit frame rate if the game supports it.
  Even with these steps, expect stutters and longer load times.

Maintenance tips to keep the phone snappy

• Keep background apps low — swipe them away from Recents.
• Disable background sync for non-essential apps.
• Use lite versions of apps (Facebook Lite, Messenger Lite).
• Clear cached data occasionally (Settings → Storage).
• If slow, backup and factory reset — this often restores usable performance on older phones.

Camera

Camera hardware

• Rear: 13 MP main camera.
• Front: 5 MP selfie camera with front LED flash.

How it performs in real life

• Daylight: Acceptable for casual sharing; colors are passable, and detail is fine for social media.
• Low light: Expect noise, soft edges, and washed-out colors; the sensor and processing are basic.
• Portrait/blur: No sophisticated depth processing — background blur won’t be natural.

Practical camera tips

• Use HDR for high-contrast scenes.
• For night shots, stabilise the phone — rest it on a surface or use a small tripod.
• Move closer rather than using digital zoom.
• Indoors, position subjects near natural light for better color and detail.

Short verdict: Good enough for casual photos and social sharing. Not for pro-level images.

Battery

Battery capacity

A 4000 mAh battery is the Hot 4 Pro’s headline feature — and with the low-resolution screen and efficient SoC, it delivers surprisingly long runtimes.

Real-world runtime

• Light use (calls, SMS, occasional browsing): 1–2 days easily.
• Moderate use (social, some video): Full day with room to spare.
• Heavy use (gaming, constant streaming): Expect 6–8 hours of screen-on time depending on brightness and connectivity.

Why is it so good

A 720p screen consumes less power, and the MT6737 was designed to be frugal. That combination means the Hot 4 Pro can often outlast phones with smaller batteries but higher-resolution displays.

Practical battery tips

• Lower screen brightness or use adaptive brightness.
• Limit auto-sync for apps that don’t need constant updates.
• Use Battery Saver around 15–20% to extend remaining time.
• Uninstall or disable apps that frequently wake the phone.
• Avoid overnight large downloads and auto-updates.

Charging note

No modern fast charging — expect a fuller-than-average charge time with the original charger (likely a few hours).

Software, updates, and security

The Hot 4 Pro ships with Android 6.0 Marshmallow + XOS. Over the years, official OS and security updates for older models usually taper off.

What this means:

• You will miss modern Android features (notifications, privacy, performance improvements) introduced after Android 6.
• Security patch frequency will be limited or stopped; for sensitive data, consider a newer phone.
• Recommended: keep apps updated from Google Play and avoid installing unknown APKs.

Comparison

Hot 4 Pro vs Hot 4

The Pro typically offers 3 GB RAM and the same 4000 mAh battery. The Pro handles multitasking better than the base Hot 4, which usually has less RAM. If the Pro costs only a bit more, choose the Pro.

Hot 4 Pro vs modern budget phones

Modern budgets often include:

• 4–8 GB RAM, smoother multitasking.
• Full HD (1080p) or better displays.
• Newer Helio G-series or Snapdragon 6/7 chips.
• Faster charging and better camera hardware/processing.
  If you need smoother performance, a better camera, and longer software support, go modern. If price and battery top your list, the Hot 4 Pro can still make sense as a budget used phone.

Who should buy the Infinix Hot 4 Pro?

Good for

• Students or seniors who primarily need calls and messaging.
• As a cheap backup phone for travel.
• Shoppers on a tight budget who value battery life over features.

Not good for

• Gamers or power users want smooth performance.
• Anyone requiring continuous security updates or modern Android features.
• Content creators are relying on high-quality cameras.

FAQs

Final verdict

The Infinix Hot 4 Pro is a budget, battery-focused phone. If your priorities are long battery life and low cost, it can still be a practical buy — especially used or as a backup device. If you care about smoother performance, better cameras, or ongoing Android/security updates, choose a newer budget phone
