Iphone 4 Vs 4s Is It Worth Upgrading In Current Year Or Should You Stick With The Older Model

In an era where smartphones evolve every few months, revisiting devices from over a decade ago might seem like nostalgia. Yet, for collectors, minimalists, or those in low-income regions relying on legacy tech, the question remains: between the iPhone 4 and iPhone 4S, is it still worth upgrading — even in 2024? While both models are long past their prime, understanding their differences helps clarify whether the 4S offers meaningful improvements or if clinging to the 4 is just as practical.

Performance and Hardware: The Core Differences

The iPhone 4 launched in 2010 with Apple’s then-revolutionary Retina display and a sleek stainless steel frame. It ran on the Apple A4 chip (though underclocked compared to the iPad version), had 512MB of RAM, and came in 16GB or 32GB storage variants. The camera was 5MP with LED flash — impressive at the time but limited by today’s standards.

The iPhone 4S followed in 2011, retaining nearly identical design but packing significant internal upgrades. It featured a faster dual-core A5 chip, double the RAM (still 512MB, but more efficiently managed), improved 8MP camera with better low-light performance, 1080p video recording, and support for faster data via HSPA+.

The most tangible difference users noticed was speed. Apps launched faster, animations were smoother, and overall responsiveness made the 4S feel more modern even when iOS updates began pushing older hardware to its limits.

Software Support and App Compatibility

This is where the gap becomes critical. The iPhone 4 supported iOS updates up to iOS 7.1.2, released in 2014. That means no security patches, no modern app compatibility, and no access to current versions of Safari, Gmail, or WhatsApp. Even basic web browsing is hampered — many sites fail to load or render incorrectly due to outdated JavaScript engines.

The iPhone 4S fared slightly better, receiving updates up to iOS 9.3.6 (released in 2016). While also obsolete, iOS 9 allowed limited functionality with some lightweight apps and better HTML5 support. However, major services like Google Maps, banking apps, and social media platforms have dropped support for iOS 9 and below.

“Devices stuck on iOS 7 or 9 aren’t just slow — they’re security liabilities. Without TLS 1.2+ support, encrypted connections fail on many modern websites.” — David Lin, Mobile Security Analyst

As of 2024, neither phone can run any app released in the last five years. Even sideloading or using third-party app stores won’t help much; most alternative ecosystems require iOS 10 or higher.

Real-World Usability Today: Can Either Phone Function as a Daily Driver?

To assess real-world value, consider what each phone can actually do now:

• Phone calls and SMS: Both work fine on GSM networks. However, AT&T shut down its 3G network in 2022, and T-Mobile plans to follow suit. Verizon already discontinued 3G. This means voice and text may fail depending on carrier and region.
• Wi-Fi connectivity: Functional, but limited. Browsing is painfully slow, and streaming audio/video often buffers or crashes.
• Camera use: The 4S captures noticeably sharper photos and handles motion better. But without cloud backup or modern editing tools, photo utility is minimal.
• Battery life: After 12+ years, original batteries are degraded. Replacement options exist, but quality varies.

A Mini Case Study: Living with an iPhone 4S in 2023

Mark, a retro tech enthusiast in Portland, tried using his preserved iPhone 4S as a minimalist device for one month. He disabled cellular, used only Wi-Fi at home, and installed a few offline apps like Notes and a basic calculator. He found that while the phone booted reliably, even loading Wikipedia on Kiwi Browser took over 45 seconds. Email via Outlook Web crashed repeatedly. He resorted to using it solely as an iPod touch replacement — playing locally stored music and using an old game or two. “It’s charming,” he said, “but not practical. I lasted 18 days before switching back.”

Is Upgrading from iPhone 4 to 4S Worth It in 2024?

From a technical standpoint, yes — the 4S is objectively better. But “worth it” depends on context:

• If you're holding onto an iPhone 4 and considering buying a 4S for $20–$40, the upgrade brings noticeable gains in speed, camera quality, and software longevity — even if marginal by today’s standards.
• If you already own a 4S, upgrading from a 4 isn't necessary unless the 4 is failing.
• If your goal is functional daily use, neither phone meets basic expectations. Even budget Android phones under $50 offer 4G LTE, modern OS support, and app compatibility.

Step-by-Step: How to Maximize Value from an Old iPhone (4 or 4S)

1. Disable Cellular: Turn off mobile data and voice. Use only Wi-Fi to avoid network dropouts.
2. Use as a Media Player: Sync music, podcasts, or audiobooks via iTunes. Works well offline.
3. Install Lightweight Web Browsers: Try iCab Mobile or Puffin Browser (if compatible) for better rendering.
4. Limited Smart Home Control: Some early HomeKit accessories worked with iOS 9 — possible niche use.
5. Emergency Backup Phone: Keep charged with essential contacts. Not reliable, but better than nothing.
6. Jailbreak (Optional): Enables customization and older app sideloading, but increases security risk.

Frequently Asked Questions

Can the iPhone 4S still make calls in 2024?

Possibly, but not reliably. Most carriers have phased out 3G, which both the 4 and 4S depend on. In areas with remaining 3G coverage, calls may work temporarily, but service will continue to degrade.

Does the iPhone 4S support Wi-Fi calling?

No. Wi-Fi calling was introduced later and requires iOS 10 or higher. Neither the 4 nor 4S supports this feature.

Is it safe to use these phones for banking or email?

No. Without updated SSL/TLS protocols and app support, logging into financial accounts poses serious security risks. Phishing, man-in-the-middle attacks, and unencrypted sessions make these devices unsafe for sensitive tasks.

Final Verdict: Upgrade Only for Nostalgia or Specific Needs

The iPhone 4S is technically superior to the 4 — faster, more capable, and slightly more future-proofed. But in 2024, that distinction matters only to collectors, hobbyists, or those repurposing the device for non-smartphone roles. For anyone needing reliable communication, internet access, or app functionality, even the most pristine 4S falls short.

If you're emotionally attached to these devices or using them as digital artifacts, upgrading from 4 to 4S makes sense. But if you're seeking practicality, consider investing in a used iPhone SE (1st gen, $30–$50 used) or an Android Go phone — both support modern apps, security updates, and 4G networks.

Technology’s value lies not in nostalgia, but in utility. The iPhone 4 and 4S were groundbreaking in their time, but their era has passed. Honor them for what they were — not what they can be today.
