🔋 CMF Phone 2 Pro Battery Drain & Charging Test: Power That Packs a Punch?
Reviewed on June 11, 2025
Why This Battery Test Matters ⚡️
In my testing, I pushed the CMF Phone 2 Pro to its limits to uncover its battery performance under real-world conditions. For budget smartphone users, battery life and charging speed are critical for daily use—whether you’re gaming, streaming, or juggling work apps. This review details how the CMF Phone 2 Pro’s battery holds up, how long it takes to charge, and whether it meets the needs of power-hungry users in 2025.
Variant Tested 🛠️
I tested the 8GB RAM + 256GB storage variant of the CMF Phone 2 Pro, priced around $249. This configuration, powered by the MediaTek Dimensity 7300 Pro chipset, is optimized for efficiency and supports expandable storage up to 2TB via microSD, making it a solid choice for users needing space for apps and media.
Battery and Charging Specifications 🔌
The CMF Phone 2 Pro is equipped with a 5,000mAh lithium-ion battery, a standard capacity for budget phones in 2025. It supports 33W fast charging with a bundled PPS charger (included in some markets, like India). There’s no wireless charging, but it offers 5W reverse wired charging for topping up accessories like earbuds.

Test Conditions and Activities 📋
I conducted the battery drain and charging tests under controlled conditions to mimic real-world usage:
- Environment: Indoor, 25°C, 50% humidity, connected to 5G and Wi-Fi (mixed usage).
- Screen Settings: 120Hz adaptive refresh rate, 50% brightness, auto-brightness off.
- Apps Tested: BGMI, YouTube, Instagram, WhatsApp, Google Maps, Chrome, and phone calls.
- Methodology: Continuous usage for drain tests, with screen-on time (SOT) tracked via Nothing OS 3.2’s battery stats. Charging tests used the included 33W charger from 0%.
Screen-On Time (SOT) Overview: The CMF Phone 2 Pro delivered an impressive 6-9 hours of SOT depending on usage intensity. Light use (social media, calls) yielded up to 9 hours, while heavy use (gaming, streaming) averaged 6 hours.
Battery Drain Test: Real-World Usage 🔍
I tracked specific app usage to measure battery drain over time, ensuring precise data for common tasks. The full drainage test ran from 100% to 0% to gauge total endurance.

Full Drainage Test ⏳
In a mixed-usage scenario (gaming, streaming, social media, calls, and navigation), the CMF Phone 2 Pro lasted 22 hours from 100% to 0%, with 6.5 hours of SOT. Starting at 8 AM, the phone was depleted by 6 AM the next day. Light usage (Wi-Fi, no gaming) extended this to 1.5 days with 9 hours SOT.
Battery Drain Insight: The 5,000mAh battery excels for casual users, offering a full day of heavy use or up to two days with light tasks. Gaming and 5G navigation drain faster, but optimization in Nothing OS 3.2 keeps efficiency high.
Charging Test: Speed and Efficiency ⚡
Using the included 33W PPS charger, I tested charging from 0% to 100% with intervals at 15, 30, and 60 minutes. The phone was powered off during charging to ensure consistency.

Charging Insight: The 33W charger is decent but not class-leading. It’s reliable for quick top-ups, hitting 50% in ~20 minutes, but competitors like the Vivo T4 (90W) charge faster. No wireless charging is a minor drawback at this price.
Battery Features and Tips 🛠️
The CMF Phone 2 Pro includes:
- Battery Saver Mode: Limits background apps and caps charging at 90%. Tip: Enable for extended light usage.
- Nothing OS 3.2 Optimization: Clean UI minimizes background drain.
- Adaptive Charging: Schedules charging to avoid overcharging. Tip: Set for overnight charging.
- 5W Reverse Charging: Charges accessories like CMF Buds. Tip: Use sparingly to preserve battery.
Rating and Conclusion 🌟
The CMF Phone 2 Pro’s 5,000mAh battery delivers reliable performance, offering 6-9 hours of SOT for most users. It shines in casual tasks like social media and streaming, with respectable gaming endurance. The 33W charging is adequate but lags behind competitors with faster solutions. For a budget phone, it strikes a great balance of efficiency and convenience.
Final Rating: 8.3/10
Verdict: A dependable choice for budget users needing all-day battery life and quick charging. Ideal for casual users, but heavy gamers may want a larger-capacity alternative.
