The OPPO A72, a mid-range smartphone from the Chinese manufacturer OPPO, has gained attention for its blend of features, affordability, and sleek design. One of the key aspects that potential buyers and current users often inquire about is the device’s storage capabilities, particularly its memory card capacity. In this comprehensive review, we will delve into every aspect of the OPPO A72’s storage options, focusing on the benefits, limitations, and practical implications of its memory card support.
1. Introduction to the OPPO A72
Before diving into the specifics of memory card capacity, it’s essential to understand the overall context of the OPPO A72. Released in 2020, the A72 is part of OPPO’s A-series, which is known for offering good value for money. The phone features a 6.5-inch IPS LCD display, a Qualcomm Snapdragon 665 processor, a quad-camera setup on the rear, and a sizable 5000mAh battery. It runs on ColorOS 7.1 based on Android 10, with upgrades available to later versions.
The OPPO A72 is available in different storage configurations, typically offering 128GB of internal storage. However, with high-definition videos, numerous apps, and large photo libraries, this internal storage can fill up quickly. This brings us to the significance of expandable storage through a memory card.
2. Memory Card Capacity and Support
One of the standout features of the OPPO A72 is its support for expandable storage. The device includes a dedicated microSD card slot, which is separate from the dual-SIM tray. This means you don’t have to choose between using a second SIM card or expanding your storage, a common compromise in many other smartphones.
2.1. Maximum Memory Card Capacity
The OPPO A72 officially supports microSD cards up to 256GB. This capacity allows users to significantly expand their storage space, making it ideal for those who frequently download large files, such as movies, music, and games, or those who store large amounts of photos and videos.
However, it’s important to note that while 256GB is the maximum officially supported capacity, some users have reported success in using 512GB microSD cards. While this may work, it’s not guaranteed by OPPO, and users may experience slower performance or other issues when exceeding the official capacity.
2.2. Types of Memory Cards Supported
The OPPO A72 supports microSD, microSDHC, and microSDXC memory cards. MicroSDHC cards typically range from 4GB to 32GB, while microSDXC cards range from 64GB to 2TB. For the best performance, it is recommended to use a Class 10 or UHS-I/UHS-II microSDXC card, especially if you plan on recording high-definition videos or using the card to store apps and games.
3. Installation and Setup
Installing a memory card in the OPPO A72 is straightforward. The phone’s SIM card tray, located on the side of the device, includes a dedicated slot for the microSD card. Users can insert the memory card without needing to remove the SIM cards, which is a convenient feature.
Once the memory card is installed, the phone will automatically recognize it, and you can choose to use it as portable storage or as internal storage. Using it as portable storage means you can use the card to store files like photos and videos, while apps will remain on the internal storage. Using it as internal storage will merge the microSD card with the internal storage, allowing you to move apps to the card. However, this latter option can sometimes lead to slower performance if the card is not of high quality.
4. Performance Considerations
While the ability to expand storage is a significant advantage, there are several performance considerations to keep in mind when using a memory card with the OPPO A72.
4.1. Speed Classes and Performance Impact
Memory cards come in different speed classes, and the class of the card you use can have a significant impact on performance. The speed class is an indicator of the minimum write speed of the card. For example:
- Class 4: Minimum write speed of 4MB/s
- Class 6: Minimum write speed of 6MB/s
- Class 10: Minimum write speed of 10MB/s
- UHS-I (U1): Minimum write speed of 10MB/s
- UHS-I (U3): Minimum write speed of 30MB/s
For the best experience, particularly if you plan to record Full HD or 4K video, or store and run apps directly from the memory card, it’s advisable to use a Class 10 or UHS-I/UHS-II card. Slower cards can lead to lag, longer load times, and stuttering when accessing files or running apps stored on the card.
4.2. Impact on Battery Life
Using a memory card can also affect the battery life of your device. This is because the phone has to power the memory card reader, which can draw additional power, especially if the card is being used for intensive tasks such as recording video or running apps. However, the impact on battery life is generally minimal, especially with modern, energy-efficient cards.
4.3. Durability and Reliability
Another factor to consider is the durability and reliability of the memory card. Not all memory cards are created equal, and cheaper or lower-quality cards can fail, leading to data loss. It’s essential to invest in a good quality memory card from a reputable brand. Cards with features like water resistance, shock resistance, and temperature resistance are preferable, especially if you plan on using the card extensively.
5. Use Cases for Expanded Storage
The benefits of expanding the OPPO A72’s storage with a memory card extend beyond just storing more files. Here are some practical use cases:
5.1. Storing Multimedia Files
One of the most common uses for a memory card is to store multimedia files such as photos, videos, and music. Given the increasing file sizes of high-definition content, the ability to add up to 256GB of additional storage is invaluable. For instance, if you frequently download movies or TV shows for offline viewing, or if you have an extensive music library, a memory card can prevent your internal storage from filling up quickly.
5.2. Photography and Videography
For users who enjoy taking photos and recording videos, especially at high resolutions, the memory card provides a significant advantage. The OPPO A72’s camera setup allows for 4K video recording, which can consume a lot of storage space. By directing the camera app to save photos and videos directly to the memory card, you can free up internal storage and avoid running out of space during important moments.
5.3. App Storage and Usage
Android allows users to move certain apps to the memory card to free up internal storage. However, not all apps support this, and some may experience reduced performance when moved to a memory card. It’s generally recommended to keep critical or frequently used apps on the internal storage and use the memory card for less demanding apps or large data files associated with apps, such as maps or offline content.
5.4. Backup and Data Transfer
A memory card can also be used as a backup solution. By regularly transferring important files to the card, you can ensure that your data is safe even if something happens to your phone. Additionally, the card can be removed and used to transfer files between devices, making it a convenient tool for users who frequently move data between their phone and other devices like laptops or tablets.
