Frequently Asked Questions

How long does the battery last on the Oppo A91?

The Oppo A91 has a 4,025 mAh battery, which in everyday mixed-use (calls, social, messaging) typically gives around a full day of usage. With lighter use (mainly standby, texting), you might stretch well into the evening or more. Heavy tasks like gaming or long video streaming will drain battery faster.

Does the Oppo A91 support fast charging, and how fast is it?

Yes — it supports VOOC Flash Charge 3.0 with 20W wired charging. It is advertised to reach about 50% battery in 30 minutes under ideal conditions.

What kind of display does the Oppo A91 have?

It features a 6.4-inch AMOLED display with Full HD+ resolution (1080 × 2400) and about 408 PPI. The panel is protected by Corning Gorilla Glass 5.

How good are the cameras—especially for low light?

The A91 has a quad rear camera setup: 48 MP main (wide), 8 MP ultrawide, plus a macro and depth sensor. Selfie camera is 16 MP. In good light, the main camera produces strong detail; in low light, images are less sharp, with more noise, especially on the ultrawide and auxiliary sensors. There is no optical image stabilization (OIS), which limits performance in darker conditions.

What are the build quality and durability features?

The phone has a Gorilla Glass 5 protected front, with a plastic frame and plastic rear panel. It weighs about 172 g and is ~7.9 mm thick. There is no confirmed high-IP water or dust resistance rating.

What software does the Oppo A91 ship with, and will it be updated?

It ships with Android 9 Pie with ColorOS 6.1. Over its lifetime it has received updates up to Android 11 in many regions. However, long-term OS version updates are limited; security patches may continue longer.

What are the known performance or usability quirks?

Users report that under heavy multitasking or with many apps open, the UI can lag or feel sluggish. Because the display is AMOLED and the phone lacks OIS, low light photography and video also show limitations. Some users noted screen brightness could be insufficient in very bright sunlight.

What network, SIM, and storage expansion options are there?

The A91 supports dual Nano-SIMs (dual standby) and a dedicated microSD card slot for storage expansion (up to ~256GB in most variants). It supports 4G LTE; 5G is not included in this model.

What unlocking & security features are included?

It has an under-display optical fingerprint sensor which unlocks fairly quickly under normal lighting. There’s also face-unlock via front camera (2D image method), which is convenient but less secure, especially in dim lighting.

What accessories and box contents usually come with the Oppo A91?

Typically the box includes the phone, a VOOC charger (compatible with its fast charge spec), USB-C cable, SIM ejector tool, quick start / warranty guide, and a protective case in many markets. Specific accessory inclusion may vary by region.
