The Apple iPhone X and OnePlus 12 represent two very different smartphone generations. The iPhone X was once Apple’s flagship, while the OnePlus 12 is a modern Android device built for current performance demands. This in-depth comparison focuses on real-world differences in performance, camera, display, battery life, and network reliability, with special consideration for the Bangladeshi market. Pricing, unofficial availability, battery aging, and daily usability are key factors for buyers in Bangladesh. This comparison breaks down, how the Apple iPhone X and OnePlus 12 compare in everyday use, based on long-term testing and market experience.

I didn’t rely on online listings alone. I physically visited Jamuna Future Park, Bashundhara City, and several local mobile shops in Dhaka, then cross-checked prices with trusted Bangladeshi online sellers. The iPhone X is no longer officially available, so everything depends on used or refurbished units. The iPhone x price in Bangladesh varies widely depending on battery health, Face ID condition, and whether any parts have been replaced. On the other hand, the OnePlus 12 is also unofficial, but mostly sold brand new through importers, which makes pricing more stable and predictable.

What You Should Know Before Buying Unofficial Units?

With the iPhone X, the biggest hidden risk is internal wear. Many units look clean outside but have weakened batteries or replaced parts that affect long-term reliability. For the OnePlus 12, the concern is less about condition and more about warranty support. In real use, a new unofficial OnePlus 12 feels far safer than a heavily used iPhone X, especially for buyers who want stress-free daily performance.

Can an old flagship still survive modern mobile games? I tested both phones as my daily gaming devices for weeks, often playing at night in warm rooms without AC. The difference was obvious within the first few sessions. The iPhone X still runs casual games fine, but modern titles quickly expose its limits. The OnePlus 12, on the other hand, feels built for sustained performance, not short bursts.

Real Gaming Experience (Daily Use)

• PUBG & COD Mobile: iPhone X needed reduced graphics to stay stable, OnePlus 12 handled high settings smoothly

• Genshin Impact: iPhone X showed frame drops and heat after 15–20 minutes, OnePlus 12 stayed playable for long sessions

• Sustained Performance: iPhone X throttles faster, OnePlus 12 maintains frame stability

• Heat Management: iPhone X gets uncomfortably warm, OnePlus 12 stays cooler in the same environment

Battery Health Reality (Gaming Perspective)

Gaming drains the iPhone X battery very quickly due to age and wear, forcing frequent charging. The OnePlus 12 handled long gaming sessions easily and still lasted the day.

Does daily signal reliability still matter more than speed numbers? After using the Apple iPhone X and OnePlus 12 as my main phones, the answer is yes, especially in BD. I tested both with Grameenphone, Banglalink, Robi, and Airtel across busy Dhaka streets, indoors, and semi-urban areas. The iPhone X handled calls fine, but mobile data often dropped indoors and in crowded areas, particularly on Banglalink and Airtel. The OnePlus 12 held stronger signals, delivered more stable 4G LTE speeds, and switched towers more smoothly. Wi-Fi performance was also more consistent on the OnePlus when multiple devices were connected. The iPhone X lacks 5G support, while the OnePlus 12 feels ready for future Bangladesh network upgrades, making it the safer long-term choice.

The iPhone X still takes decent photos in good light, but consistency is the issue now. The OnePlus 12 feels far more reliable in everyday shooting.

• iPhone X daylight photos look natural but lack fine details

• Low-light shots on iPhone X show noise and need multiple tries

• Night photos often lose sharpness on the iPhone X

• OnePlus 12 captures brighter, sharper photos with better dynamic range

• Indoor and night shots are more dependable on the OnePlus 12

• Video is usable on both, but OnePlus 12 feels more consistent overall

Both screens look good at first glance, but long daily use shows clear differences.

• iPhone X OLED display panel still looks sharp indoors

• Standard refresh rate on iPhone X now feels slow while scrolling

• OnePlus 12 display feels smoother and more modern

• Outdoor visibility is clearly better on the OnePlus 12

• Reading, social media, and videos feel easier on the eyes on OnePlus 12

• Long screen time is more comfortable on the OnePlus 12

Choose the iPhone X only if you want a small iPhone for light use. For speed, battery, gaming, camera, and future network support, the OnePlus 12 is the smarter buy.

After a full month of real use, the OnePlus 12 fits modern Bangladeshi needs far better. The iPhone X still works, but it no longer feels practical.

Which phone heats more during gaming?

The OnePlus 12 easily lasts longer. Used iPhone X units often struggle due to battery degradation.

Is 5G important when choosing between them?

Yes. The OnePlus 12 supports 5G network, while the iPhone X is limited to older networks.

Which is better value in Bangladesh market now?

The OnePlus 12 offers better long-term value with stronger performance and future-proof features.
