Display Comparison
Neither device boasts a standout display. Both likely utilize LCD panels, common in this price bracket. However, the lack of detailed display specs for the K31 makes a direct comparison difficult. The Moto G Stylus 5G benefits from a larger screen size, which is advantageous for media consumption. The K31’s display resolution is likely 720p, while the Moto G Stylus 5G is 1080p, resulting in a sharper image on the Motorola device. The 8nm Snapdragon 480 in the Moto G Stylus 5G allows for more efficient display power management.
Camera Comparison
Camera performance is likely similar in real-world scenarios, given the focus on affordability for both devices. Detailed camera specs are missing for the LG K31, but it likely features a basic sensor setup. The Moto G Stylus 5G’s camera system, while not flagship-level, benefits from Qualcomm’s image signal processor (ISP) within the Snapdragon 480, offering improved image processing capabilities. The Moto G Stylus 5G likely has a larger main sensor, resulting in better low-light performance. The inclusion of 5G connectivity on the Motorola device also allows for faster uploads of photos and videos.
Performance
The performance gap is substantial. The Motorola Moto G Stylus 5G’s Qualcomm Snapdragon 480 5G (8nm) is a clear upgrade over the LG K31’s MediaTek Helio P22 (12nm). The 8nm process node of the Snapdragon 480 translates to better power efficiency and reduced thermal throttling under sustained loads. The Snapdragon 480’s Kryo 460 cores, with their 2x2.0 GHz and 6x1.8 GHz configuration, offer a more sophisticated architecture than the K31’s Octa-core 2.0 GHz Cortex-A53 setup. This means faster app loading times, smoother multitasking, and a more responsive user experience on the Motorola device. Gamers will find the Moto G Stylus 5G capable of handling less demanding titles, while the K31 will struggle with anything beyond basic games.
Battery Life
The Moto G Stylus 5G’s 10W charging is slow by modern standards, but the Snapdragon 480’s efficiency helps offset this. The Helio P22 in the K31, being a less efficient chip, will likely drain the battery faster under similar usage. While battery capacity isn’t specified for either device, the Moto G Stylus 5G’s more efficient chipset will likely provide comparable or better real-world battery life despite potentially having a similar capacity. The 8nm process node of the Snapdragon 480 contributes significantly to this improved efficiency.
Buying Guide
Buy the LG K31 if you absolutely need the lowest possible upfront cost and 5G isn't a priority. It's suitable for basic tasks like calls, texts, and light social media. Buy the Motorola Moto G Stylus 5G if you want a more responsive experience, 5G connectivity for faster data speeds, and the added functionality of a stylus for note-taking and creative tasks. It’s the better long-term investment.
