About the Oppo A57s
The Oppo A57s is a straightforward budget phone that concentrates on the things people at this end of the market actually complain about: battery life, charging speed and build. The 5,000mAh cell will see most users into a second day, and 33W charging is unusually quick for a phone in this bracket, so a short spell on the mains gets you back to useful. Oppo also fitted stereo speakers, an IP54 rating against dust and splashes, a side-mounted fingerprint reader and a microSD slot, which together make it feel a cut above the cheapest handsets. The compromises are just as clear. The Helio G35 is an entry-level chip that will feel slow if you push it, the 6.56-inch screen is only HD+ rather than Full HD+, and the 50MP main camera is fine outdoors but struggles indoors and at night. There is no 5G either, so this is a 4G phone on every UK network. For calls, messaging, streaming and social apps it does the job without fuss - just do not expect it to keep up with gaming or heavy multitasking.

Oppo A57s Specifications
Spec Scores
Under £200 Phones · 128 phones
- Helio G35
- Octa-core (4x2.3 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53)
Based on calibrated CPU benchmark rankings (60%) and GFXBench GPU scores (40%). Apple chipsets included via editorial calibration since AnTuTu under-represents Apple's architecture.
- 6.56 inches
- 720 x 1612 pixels
- IPS, 600 nits peak
Based on panel type (LTPO is the modern flagship gold standard), resolution, refresh rate, peak brightness, screen size, and HDR10+ / Dolby Vision support. Marketing peak-brightness claims are capped at 3500 nits to prevent inflation.
- Single camera setup
- 50 MP main camera
- 1080p video recording
Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.
- 8 MP front camera
- 1080p selfie video
Based on selfie megapixels and max selfie-video resolution.
- 5,000 mAh
- 33W wired, 100% in 69 min
Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
