The overall camera performance are pretty decent and at some points the ColorOS’s A.I. tend to sharpen and boost-up the contrast. Maybe this is some what the end-user want to see.

Performance & Software

This is a quite disappointment where the MediaTek Helio P70 is rather old at this pint of time.

Here are some benchmark score result

The OPPO A91 is running on ColorOS 6.0 based on Android 9 Pie. Hope that the more clean and fluid ColorOS 7.0 to release onto the OPPO A91.

Battery & VOOC Flash Charge 3.0

It packed with a decent size of 4,025 mAh battery and supports the new 20W VOOC Flash Charge 3.0. This is a huge improvement to features on a mid-range device.

The battery life of the device is just average and can deliver around 4 to 5 hours of screen on time.

The OPPO A91 is a great mid-range a smartphone to recommend in 2019 but not 2020. It has a great AMOLED display, decent camera and fast charging speed. The only drawback is a little outdated chipset that uses on the device.

For the price of RM 999, there is a list of strong competitions out there. Unless you are into the design and camera, where gaming performance is not your priority.
