Some phones feel like tools. Others feel like habits you slowly build your day around. Using the OnePlus 12 and the iPhone 12 Pro side by side, that difference becomes very clear over time. One feels open, generous, almost stress-free during long nights of scrolling, videos, and gaming. The other feels compact, polished, familiar, but slightly tense as hours pass. This isn’t about raw power on paper. It’s about how relaxed your hands feel, how often you check battery percentage, how warm the phone gets after midnight, and whether your eyes feel calm or strained. In this comparison, I’ll walk through real daily usage, pricing realities, performance under pressure, cameras, display comfort, and long-term usability, focusing on how each phone truly fits into everyday life.

The OnePlus 12 is officially available in Bangladesh. Authorized retailers usually price it between BDT 1,05,000 and 1,10,000. This official price includes brand warranty, service-center access, and bank EMI options, which matter for long-term use. During Eid or major sales, the price can drop slightly, especially for cash buyers.
The same phone is also sold in the grey market, where unofficial units typically cost BDT 80,000 to 98,000. These come with shop warranty only, not official support.

The iPhone 12 Pro is not officially sold in Bangladesh anymore. There is no official price. All available units are grey-market imports, usually priced between BDT 55,000 and 146,000, depending on storage and condition. Warranty is limited to the shop, which lowers the price but increases long-term risk.

In Dhaka markets like Bashundhara City, bargaining is common, and buyers at these prices often compare alternatives such as the Samsung Galaxy S23 FE, Xiaomi 14T, or Apple iPhone 13 before deciding.

Performance differences between the OnePlus 12 and iPhone 12 Pro become clear during longer gaming sessions, not quick app launches. In warm rooms without AC, sustained use matters more than peak speed. Over time, one phone stays relaxed, the other starts to manage itself.

Real-World Gaming & Performance Behavior

• OnePlus 12: The OnePlus 12 maintains stable frame rates during long PUBG, COD Mobile, or Genshin Impact sessions. Heat builds gradually and spreads evenly, so hand comfort stays reasonable even after 40-60 minutes. Multitasking remains smooth with fewer app reloads. According to NanoReview, the cheapest AnTuTu score is around 1.9 million, giving the phone clear performance headroom that shows up as steady gameplay rather than raw numbers.

• Apple iPhone 12 Pro: The iPhone 12 Pro feels very fast at the start, with smooth animations and quick game launches. However, in warm conditions, heat builds faster, and after 20-30 minutes, frame stability can dip slightly as thermal control kicks in. NanoReview lists the cheapest AnTuTu score at roughly 630,000, which explains why sustained performance feels more limited today.

After a few days, the phones stop trying to impress you and that’s when the real competition begins. The OnePlus 12 quietly invites you to stay longer. The iPhone 12 Pro keeps things polished and familiar, but reminds you to be a little more careful. That subtle push and pull defines how they fit into daily life.

What You Notice in Daily Use

• Long-Hour Comfort
  With the OnePlus 12, long scrolling sessions and late-night videos feel easier on the hands and eyes. The iPhone 12 Pro still feels premium, but extended use can feel slightly cramped and tiring.

• Battery Behavior
  OnePlus 12 lets you forget the battery for most of the day. The iPhone 12 Pro makes you check it more often, especially in the evening.

• Heat & Handling
  OnePlus warms up gradually and stays comfortable. The iPhone heats faster under pressure, which you notice during gaming or video calls.

• Night-Time Use
  OnePlus feels calmer late at night. The iPhone stays sharp and clean, but can feel harsher over time.

Network performance in Bangladesh isn’t just about signal bars, it’s about how a phone behaves inside concrete buildings, during peak-hour congestion, and while moving between areas. Using the OnePlus 12 and iPhone 12 Pro across daily routines calls, mobile data, navigation, and wireless accessories both are reliable, but they handle pressure differently. Neither struggles outright, yet one feels more forgiving when conditions aren’t ideal.

Real-World Connectivity Experience

• 2G / 3G Support
  Both phones support 2G and 3G, which still matters in rural pockets and during fallback situations. Call reliability remains solid on both when data drops to older networks.
• 4G LTE Performance
  On Grameenphone, Robi, and Banglalink, both phones deliver stable 4G LTE performance. The OnePlus 12 tends to hold usable data speeds longer during peak congestion, especially in crowded urban areas. The iPhone 12 Pro remains reliable, but LTE speeds can dip sooner when towers are overloaded.
• 5G Readiness
  The OnePlus 12 supports 5G Network and is future-ready for Bangladesh’s gradual rollout. While 5G availability is still limited, this adds long-term value. The iPhone 12 Pro also supports 5G Network, but its older modem feels less efficient under mixed coverage conditions.

• Indoor & Building Penetration
  Inside concrete apartments, offices, and shopping malls, the OnePlus 12 generally maintains usable mobile data longer before dropping to slower speeds. The iPhone 12 Pro still connects, but signal strength fluctuates more noticeably in deeper indoor locations.

• Travel & GPS Reliability
  Both phones lock GPS quickly and remain accurate during rides or navigation. The iPhone feels slightly more precise in dense urban areas, while the OnePlus stays dependable during longer trips without sudden drops.

• Wi-Fi & Bluetooth Use
  Wi-Fi stability is solid on both during video calls and streaming. Bluetooth connections with earbuds and car systems remain reliable, though the OnePlus feels a bit more tolerant of distance and interference.

Camera differences between the OnePlus 12 and iPhone 12 Pro show up in everyday moments quick photos, night scenes, and short videos. Both are reliable, but their priorities are different: flexibility versus consistency.

Rear Camera (Main & Supporting Lenses)

As stated by GSMArena, the OnePlus 12 uses a 50MP main camera, supported by a 64MP telephoto and a 48MP ultra-wide lens. In daily use, this setup delivers noticeably sharper photos, especially in daylight and detailed scenes like streets or landscapes. Low-light shots come out brighter with more visible detail, making night photos easier to capture, though colors can look slightly boosted at times.
The iPhone 12 Pro relies on a 12MP triple-camera system (main, ultra-wide, telephoto). While the resolution is lower, Apple’s processing keeps exposure and colors very consistent. Photos look natural and balanced, with fewer surprises, even if they don’t match the raw detail level of the OnePlus.

Front Camera (Selfies & Video Calls)

The OnePlus 12 features a 32MP front camera, producing sharper selfies in good lighting with more visible facial detail. The iPhone 12 Pro uses a 12MP front camera, focusing less on sharpness and more on accurate skin tones and controlled highlights, which many users prefer for portraits and video calls.

Video Recording

For video, the Apple iPhone 12 Pro still feels more polished, with better stabilization and consistent colors. The OnePlus 12 delivers clear video with stronger low-light brightness, but stabilization is slightly less refined.

Display quality matters most after long hours, not at first glance. That’s where the OnePlus 12 and iPhone 12 Pro start to feel different in daily use.

• The OnePlus 12 uses a large AMOLED panel with high pixel density, deep contrast, rich color depth, and very high brightness. Outdoors, the screen stays clearly visible under strong sunlight. Indoors and at night, it feels easier on the eyes during long scrolling or video sessions, making late-night use more comfortable.
• The iPhone 12 Pro features a Super Retina XDR OLED display with excellent sharpness and accurate colors. Text and images look precise, but the smaller screen and lower brightness make outdoor viewing slightly harder, and long night sessions can feel more tiring.

Pick the OnePlus 12 if you want longer battery life, smoother gaming, and a more comfortable screen for daily use. Choose the iPhone 12 Pro if you prefer a compact phone, reliable cameras, and Apple’s ecosystem.

The OnePlus 12 is the more balanced choice for most users today, offering stronger performance, better comfort, and longer usability. The iPhone 12 Pro remains refined and reliable, but its age shows in sustained use.
