Oppo A3x

At Rs. 27,999, the Oppo A3x is fair value for buyers who rank battery life, charging speed and brand trust above performance and cameras. Its strengths are real: a 5100mAh battery, 45W charging with the charger in the box, a bright 90Hz screen, a side fingerprint sensor, a 3.5mm headphone jack and a microSD slot.

The weaknesses are just as clear. The phone uses eMMC 5.1 storage, the cameras are basic and the chipset is modest. Opinions differ on the price: some see it as a sensible branded option, while others call it overpriced for its memory, especially the 4GB/64GB version.

• Buy it for: long battery life, quick charging and outdoor screen visibility.
• Skip it if: you want better cameras or smoother gaming. The Xiaomi Redmi 14C offers higher-resolution cameras and a 120Hz screen for slightly less, but charges far more slowly.

Verdict: a dependable everyday phone, but the 128GB version is the more sensible choice if the price gap is small.

The Oppo A3x has a 6.67-inch IPS LCD with HD+ (720 x 1604) resolution and a 90Hz refresh rate. The settings offer three modes: Auto changes the refresh rate as needed, Standard uses the normal rate to save power, and High keeps it at 90Hz.

Brightness is the highlight. The panel is rated at up to 1000 nits in sunlight, and the screen stays easy to read outdoors, which is uncommon at this price. Colours look pleasant for social media and video, and scrolling feels smooth for a budget phone.

The limits are resolution and refresh rate. At 720p, text and video look less crisp than on a Full HD screen, and anyone moving from a 120Hz phone will find 90Hz slower. The screen has a centred punch-hole instead of a notch, uses Panda glass, and Oppo's Splash Touch keeps it responsive with wet fingers.

The phone runs on the Qualcomm Snapdragon 6s 4G Gen 1 with an Adreno 610 GPU, LPDDR4X RAM and eMMC 5.1 storage. It handles calls, messaging, browsing, social media and video without trouble, and it does not heat up much in normal use.

It is not a gaming phone. Games run if you accept lower graphics settings, but overall the phone feels a little slow next to rivals. The bigger long-term concern is storage: eMMC is slower than UFS, so copying files and installing apps can slow down noticeably once the storage fills up after six months to a year.

• Virtual RAM can borrow storage space, but it does little in real use.
• A microSD card adds storage space, not memory for multitasking.

For calls, messaging and light apps, one to two years of comfortable use is a realistic expectation.

The rear camera is an 8MP f/2.0 main sensor with a secondary depth lens, and the front camera is 5MP f/2.2. Both record video at up to 1080p at 30fps, and the rear camera offers 2x zoom for photos and video.

In good light, the rear camera takes decent photos, and Pro mode helps produce better video. Night mode makes low-light shots usable, but detail stays limited. The selfie camera is fine in daylight but becomes poor in low light, and front-camera video has little detail and weak dynamic range.

• Beauty mode is on by default for selfies; switch it off for natural skin tones. Oppo's AI Portrait Retouching effect can be adjusted.
• Modes include night, portrait, time-lapse, sticker and text scanner, but there is no slow motion.

Buyers who care most about photos or video should look at rivals with higher-resolution cameras.

The Oppo A3x has a 5100mAh battery that comfortably lasts a full day, with around 7 to 8 hours of screen-on time in mixed use. The efficient chipset helps here.

Charging is a real advantage at this price. The phone supports 45W SUPERVOOC charging, a 50% charge takes about 30 minutes, and Oppo's official spec page confirms that the charger is included in the box.

Oppo also claims the battery keeps most of its capacity after years of use. This is based on its own lab charge-cycle tests, so treat it as a manufacturer claim rather than a guarantee.

The Oppo A3x launched with Android 14 and ColorOS 14 and is listed as upgradable to Android 15 with ColorOS 15. ColorOS is feature-rich and easy to customise, with useful extras such as Ultra Volume Mode for louder calls in noisy places and AI Portrait Retouching for selfies.

Oppo's official spec page does not state an update commitment, so the number of future Android versions and the length of security support are not confirmed. Buyers who plan to keep the phone for many years should not count on a long update life.

Oppo also promotes long-term smoothness from its Trinity Engine, but that is a performance claim from lab testing, not a software update promise.
