In the rapidly moving world of consumer electronics, a five-year-old smartphone is often considered "ancient history."
However, Apple has built a reputation for longevity that few can match. As we enter 2025, the iPhone 12—originally released in late 2020—remains one of the most intriguing devices on the second-hand and refurbished markets.
This extensive review explores the iPhone 12's relevance today. We will break down what made it a pioneer, how it holds up against the modern standards of 2025, and whether it is a "smart buy" or a "pass" for your specific needs.
1. The Legacy: What Was New with the iPhone 12?
To understand if the iPhone 12 is worth it today, we must revisit the massive leap it represented over the iPhone 11. It wasn't just an incremental update; it was a foundational shift for the modern iPhone era.
The Return of the Flat Edge
The most striking change was the design. Apple ditched the rounded edges of the iPhone 6 through 11 and returned to the industrial, flat-edge aesthetic first seen in the iPhone 4 and 5. This design persists in the current iPhone 16 lineup, meaning an iPhone 12 doesn't look "old" at a glance.
The OLED Revolution (Super Retina XDR)
Before the iPhone 12, the standard models (like the iPhone 11 and XR) used LCD screens with lower resolutions. The iPhone 12 brought OLED technology to the baseline model.
Contrast: Infinite contrast ratios with true blacks.
Resolution: A jump from 828p to 1170 x 2532 pixels, making everything significantly sharper.
Brightness: Peak brightness of 1,200 nits for HDR content.
5G Connectivity
The iPhone 12 was the first Apple device to support 5G networks. While 5G was a luxury in 2020, it is a necessity in 2025. Buying an iPhone 12 ensures you aren't stuck in the slow lane of 4G LTE as carriers continue to prioritize 5G infrastructure.
Ceramic Shield and MagSafe
Apple introduced Ceramic Shield, a glass-ceramic hybrid that offered 4x better drop performance. Furthermore, MagSafe was born—the magnetic ring on the back that revolutionized wireless charging and accessories like wallets and car mounts.
2. Performance in 2025: The A14 Bionic vs. Modern Apps
The heart of the iPhone 12 is the A14 Bionic. In 2020, it was the first 5nm chip in a smartphone. But how does it handle the bloated apps and heavy websites of 2025?
Everyday Speed
For social media (TikTok, Instagram), messaging (WhatsApp, iMessage), and web browsing, the iPhone 12 feels remarkably fluid. iOS is exceptionally well-optimized for this silicon. You likely won't notice a difference in "app opening speeds" compared to an iPhone 15 in casual use.
Gaming and Multitasking
With 4GB of RAM, the iPhone 12 starts to show its age in extreme multitasking. If you are a heavy gamer playing titles like Genshin Impact or Zenless Zone Zero, you might need to turn down graphic settings to "Medium" to maintain a stable 60fps and prevent the phone from heating up.
3. Camera Quality: Can 12MP Still Compete?
The iPhone 12 features a dual 12MP system (Wide and Ultra-Wide). While 48MP sensors are now the standard for "Pro" models, the iPhone 12’s computational photography remains impressive.
Night Mode: Available on all cameras, including the front-facing TrueDepth camera. It still takes excellent, low-noise photos in dark environments.
Deep Fusion & Smart HDR 3: These algorithms ensure that textures (like fabric or hair) are sharp and skin tones are natural.
Video Mastery: This was the first phone to record in Dolby Vision HDR. Even in 2025, the video quality of an iPhone 12 is superior to many brand-new mid-range Android phones.
Note: The main limitation in 2025 is the lack of a dedicated Telephoto lens. If you need to zoom in on subjects frequently, you will notice significant graininess as the digital zoom takes over.
4. The 2025 Battery Reality
This is the iPhone 12's "Achilles' heel." The battery capacity is 2,815 mAh, which was modest even at launch.
Chemical Aging: Most used/refurbished iPhone 12s in 2025 will have a battery health percentage between 80% and 88%.
5G Drain: 5G is power-hungry. On a heavy day of usage, an iPhone 12 will struggle to reach 6:00 PM without a top-up.
The Solution: If you buy this phone in 2025, factor in the cost of a battery replacement (approx. $89 / Rp 1.500.000) or carry a MagSafe power bank.
5. Software Support: How Much Time is Left?
Apple typically supports iPhones for 6 to 7 years.
iOS 18 (2024): Fully supported.
iOS 19 (2025): Almost certainly supported.
iOS 20 (2026): Likely the final major update.
Security Patches: Apple often continues to provide critical security updates for 2 years after major OS support ends.
This means if you buy an iPhone 12 today, you can expect a "safe" and modern experience until at least late 2027.
6. Price Analysis: Is it a Bargain?
In 2025, you should not be buying a brand-new iPhone 12 (if you can even find one). The value lies in the Refurbished/Second-hand market.
| Condition | Estimated Price (2025/2026) | Recommendation |
| Used (Marketplace) | Rp 4.500.000 - Rp 5.200.000 | Good for budget seekers. |
| Refurbished (Certified) | Rp 5.500.000 - Rp 6.000.000 | Best value with warranty. |
| iPhone 13 (Refurbished) | Rp 7.500.000+ | Consider if you need better battery. |
7. Verdict: Is it Worth It in 2025?
The iPhone 12 is a "Value King" for a specific type of user. It is the cheapest "modern-looking" iPhone that supports 5G and has a high-quality OLED screen.
✅ Buy it if:
You are on a strict budget but want the "Apple Ecosystem" (iMessage, AirDrop, Apple Watch).
You are buying a first phone for a child or a secondary device for work.
You prefer a lighter, thinner phone (it is significantly lighter than the 13, 14, or 15).
❌ Skip it if:
You are a "power user" who spends 6+ hours a day on your phone (The battery will frustrate you).
You plan to keep the phone for more than 3 years (Go for the iPhone 13 or 15 instead).
You need high-quality zoom photography.
Final Thoughts
The iPhone 12 is the "threshold" device. Anything older (like the iPhone 11) is now difficult to recommend due to the lack of 5G and the dated LCD screen. The iPhone 12 remains a solid, functional, and stylish piece of technology that proves Apple's engineering stands the test of time.
