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.

Frequently asked questions
Is the Oppo A57s worth buying?
The Oppo A57s is worth buying if you want long battery life, fast 33W charging and a splash-resistant build on a small budget. The Helio G35 chip is slow for gaming and the screen is only HD+, so it suits light users rather than anyone who pushes their phone hard.
Does the Oppo A57s have 5G?
No. The Oppo A57s is a 4G-only phone, built around the MediaTek Helio G35, so it will not connect to 5G on any UK network. If 5G is essential, you will need to look at a different model in Oppo's A range.
How long does the Oppo A57s battery last?
The 5,000mAh battery paired with a low-power HD+ screen and an efficient entry-level chip typically delivers well over a day, and lighter users often reach two days. It charges at 33W, which is quick for a budget phone and gets you a meaningful top-up in around 30 minutes.
Is the Oppo A57s camera good?
The 50MP main camera produces acceptable photos in good outdoor light, but detail and colour fall away quickly indoors and at night. The 2MP depth and macro lenses add little, and the 8MP front camera is basic. Treat it as a camera for snapshots rather than for anything you want to print.
Does the Oppo A57s have a headphone jack and expandable storage?
Yes. The Oppo A57s keeps a 3.5mm headphone socket and takes a microSD card to expand on its 64GB or 128GB of internal storage. It also has NFC for contactless payments and stereo speakers, which are not a given at this price level.
What is the difference between the Oppo A57s and the Oppo A17?
Both use the same Helio G35 chip and a 6.56-inch HD+ screen, so performance is effectively identical. The A57s adds a third rear camera, an IP54 rating, stereo speakers and much faster 33W charging, and it is slightly lighter and slimmer. The A17 is the more basic option of the two.

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. Where DXOMARK has lab-tested the phone, its measured score replaces this estimate.

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.
