Battery life is one of the most critical factors when choosing a smartphone. Both OPPO and Samsung offer a wide range of devices, but their approaches to battery technology, charging speeds, and software optimization differ significantly. This article compares battery performance across popular OPPO and Samsung models, using real-world testing data and specifications. We focus on flagship and mid-range devices available in the Netherlands and Europe, with prices in euros (€) and references to local retailers.
Battery Capacity and Hardware
OPPO and Samsung equip their phones with batteries ranging from 4,000 mAh to 5,000 mAh, but capacity alone doesn't determine real-world endurance. The efficiency of the processor, screen technology, and software play a major role.
Flagship Models
- OPPO Find X5 Pro: 5,000 mAh battery, Snapdragon 8 Gen 1, 6.7-inch LTPO2 AMOLED at 120 Hz. In PCMark battery tests, it lasts about 12 hours and 30 minutes. Real-world usage (mixed Wi-Fi/4G, social media, video) yields around 7-8 hours of screen-on time.
- Samsung Galaxy S22 Ultra: 5,000 mAh battery, Exynos 2200 (Europe) or Snapdragon 8 Gen 1, 6.8-inch Dynamic AMOLED 2X at 120 Hz. PCMark battery test results are slightly lower at around 11 hours. Real-world screen-on time is typically 6-7 hours.
- Samsung Galaxy S23 Ultra: 5,000 mAh battery, Snapdragon 8 Gen 2 for Galaxy, more efficient. PCMark scores exceed 13 hours, and real-world screen-on time reaches 8-9 hours.
The newer Samsung flagship with the custom Snapdragon chip closes the gap with OPPO. However, OPPO's ColorOS software is often praised for aggressive background app management, which can extend standby time.
Mid-Range Models
- OPPO Reno 8 Pro: 4,500 mAh battery, MediaTek Dimensity 8100-Max. Real-world screen-on time of about 7 hours. Excellent for the price (€500-€600).
- Samsung Galaxy A53 5G: 5,000 mAh battery, Exynos 1280. Despite larger capacity, screen-on time is around 6-7 hours due to less efficient chipset.
- Samsung Galaxy A54 5G: 5,000 mAh battery, Exynos 1380. Improved efficiency yields about 7-8 hours screen-on time.
Mid-range OPPO phones often match or exceed Samsung's endurance despite smaller batteries, thanks to more efficient MediaTek chips and lighter software.
Charging Speed
OPPO is famous for its proprietary VOOC (Voltage Open Loop Multi-step Constant-Current Charging) technology, rebranded as SuperVOOC. Samsung uses standard USB Power Delivery (PD) and its own Adaptive Fast Charging.
Wired Charging
| Model | Max Wired Charging | 0-100% Time |
|---|---|---|
| OPPO Find X5 Pro | 80W SuperVOOC | ~35 minutes |
| Samsung Galaxy S23 Ultra | 45W USB PD | ~60 minutes |
| OPPO Reno 8 Pro | 80W SuperVOOC | ~30 minutes |
| Samsung Galaxy A54 | 25W USB PD | ~85 minutes |
OPPO charges significantly faster across all price tiers. Samsung's 45W charging is only available on its Ultra models and still lags behind OPPO's 80W. OPPO's 80W charger is included in the box in Europe, while Samsung typically sells chargers separately, adding €20-€30 to the cost. For advice on choosing chargers, see our fast chargers comparison.
Wireless Charging
Samsung offers 15W wireless charging on most flagships (Galaxy S series and Note series), while OPPO's Find X5 Pro supports 50W AirVOOC wireless charging. In practice, Samsung's wireless charging is slower: a Galaxy S23 Ultra takes about 2 hours to fully charge wirelessly, whereas the Find X5 Pro takes only 50 minutes. However, Samsung's phones support standard Qi charging, making them compatible with a wider range of third-party pads. OPPO's fast wireless charging requires proprietary AirVOOC chargers, which are less common.
Software Optimization and Battery Management
Battery life is not just about hardware; software plays a crucial role. OPPO's ColorOS (based on Android) includes aggressive battery optimization features like Super Power Saving Mode and App Freezer. Samsung's One UI offers similar tools but tends to be less restrictive.
Background App Management
OPPO's ColorOS can freeze apps that are not used for a long time, preventing them from draining battery in the background. This can improve standby time by 10-15% compared to Samsung's default settings. However, it may also delay notifications from apps like WhatsApp or email. Samsung's One UI is more balanced, keeping apps alive for timely notifications but consuming slightly more standby power.
Battery Health Features
Both brands include features to preserve battery longevity. OPPO's Smart Charging learns your sleep schedule and pauses charging at 80% until you wake up. Samsung's Protect Battery feature caps charging at 85% manually. Neither is perfect, but they help extend battery lifespan.

Real-World Battery Life Tests
We compiled data from independent reviewers (GSMArena, Notebookcheck) for typical usage patterns. Tests include video playback, web browsing, and 4G calling.
Video Playback (1080p, offline)
- OPPO Find X5 Pro: 16 hours 30 minutes
- Samsung Galaxy S23 Ultra: 17 hours 10 minutes
- OPPO Reno 8 Pro: 14 hours
- Samsung Galaxy A54: 15 hours
Samsung slightly edges ahead in video playback due to more efficient display drivers.
Web Browsing (Wi-Fi, 120 Hz)
- OPPO Find X5 Pro: 12 hours 20 minutes
- Samsung Galaxy S23 Ultra: 11 hours 45 minutes
- OPPO Reno 8 Pro: 11 hours
- Samsung Galaxy A54: 10 hours 30 minutes
OPPO leads in web browsing, likely due to better CPU power management.
4G Calling
Both brands perform similarly, with talk times exceeding 25 hours on flagship models. Mid-range phones average 20-22 hours.
Price vs Battery Performance
Battery performance must be considered alongside price. In the Netherlands, typical retail prices (as of 2024) are:
- OPPO Find X5 Pro: €1,099 (currently discounted to ~€899 at Belsimpel)
- Samsung Galaxy S23 Ultra: €1,399 (€1,199 at MediaMarkt)
- OPPO Reno 8 Pro: €599 (€499 at Coolblue)
- Samsung Galaxy A54: €449 (€399 at Bol.com)
For the price, OPPO offers faster charging and comparable battery life. Samsung's Ultra models command a premium but provide slightly better video playback and wireless charging ecosystem.
Durability and Repairability
Battery replacement costs and ease of repair are important for long-term ownership. Samsung has a more extensive network of authorized service centers in the Netherlands (e.g., Samsung Service Center Amsterdam). OPPO's service network is smaller, but third-party repair shops often handle both brands. For screen repairs, see our guides: OPPO Find X5 screen replacement and Samsung Galaxy S22 screen repair. Water damage can also affect battery life; read about Samsung water damage repair.
Conclusion
OPPO generally offers faster charging and competitive battery life across its lineup, especially in the mid-range. Samsung excels in video playback and wireless charging convenience, but its charging speeds are slower. For users who prioritize quick top-ups and all-day endurance, OPPO is the better choice. For those who want a balanced ecosystem and longer video playback, Samsung remains strong. Ultimately, both brands deliver reliable battery performance, but your specific usage patterns should guide your decision.
