Samsung Galaxy M21s

  • Potentially lower initial purchase price.
  • Samsung brand recognition.
  • Adequate for basic smartphone tasks.

  • Older Exynos 9611 chipset.
  • Less efficient 10nm process.
  • Potential for thermal throttling.

Motorola Moto G Power (2021)

  • More efficient Snapdragon 662 chipset.
  • 11nm fabrication process for better battery life.
  • Smoother multitasking and gaming experience.

  • Motorola’s software update track record is less consistent than Samsung’s.
  • May be slightly more expensive upfront.

Display Comparison

Neither device boasts a particularly standout display. Both likely utilize LCD panels, a common trait in this price bracket. However, the lack of detailed display specs (resolution, brightness) necessitates a focus on processing power as the differentiating factor. The M21s' display is likely adequate for everyday use, but the G Power's more efficient chipset may translate to slightly better battery life even with similar display usage.

Camera Comparison

Without detailed camera sensor information, a direct comparison is difficult. However, it’s safe to assume both phones feature a primary camera accompanied by several auxiliary lenses (likely including a depth and macro sensor). The image processing capabilities of Qualcomm’s ISP in the Snapdragon 662 are generally considered more refined than Samsung’s equivalent in the Exynos 9611, potentially resulting in more natural-looking photos. The presence of a larger main sensor (if any) would be a significant advantage, but this information is unavailable.

Performance

The core difference lies in the chipsets. The Motorola Moto G Power (2021) features the Qualcomm Snapdragon 662 (11nm), while the Samsung Galaxy M21s uses the Exynos 9611 (10nm). The Snapdragon 662’s 11nm fabrication process generally leads to improved power efficiency compared to the 10nm Exynos 9611. While both are octa-core CPUs, the Snapdragon’s Kryo 260 Gold cores clocked at 2.0 GHz offer a slight architectural advantage over the Exynos’ Cortex-A73 cores at 2.3 GHz. This translates to better sustained performance and less thermal throttling during demanding tasks. The G Power will likely handle multitasking and moderate gaming more smoothly.

Battery Life

Both phones support 15W wired charging, a relatively slow standard. The actual battery capacity isn't provided, but the Snapdragon 662’s superior power efficiency in the Moto G Power (2021) will likely result in longer real-world battery life despite potentially having a similar capacity to the M21s. The 11nm process allows the G Power to extract more usage from each charge, making it a better choice for users who prioritize longevity.

Buying Guide

Buy the Samsung Galaxy M21s if you prioritize a potentially lower initial price and are primarily focused on basic tasks like calling, texting, and light social media use. Buy the Motorola Moto G Power (2021) if you prefer a smoother, more responsive experience for multitasking, moderate gaming, and benefit from a more modern and efficient chipset that will likely receive longer software support.

Frequently Asked Questions

❓ Does the Exynos 9611 in the Galaxy M21s overheat during prolonged gaming sessions?
The Exynos 9611, built on a 10nm process, is prone to thermal throttling under sustained load. While it can handle casual gaming, demanding titles will likely experience performance drops as the chip heats up. The Motorola Moto G Power (2021)'s Snapdragon 662, with its 11nm process, manages heat more effectively, providing a more consistent gaming experience.
❓ How does the Snapdragon 662 in the Moto G Power (2021) handle multitasking compared to the Exynos 9611?
The Snapdragon 662 generally offers superior multitasking performance due to its more efficient architecture and better memory management. The Exynos 9611 may struggle with numerous apps open simultaneously, leading to lag and slowdowns. The Moto G Power (2021) will provide a smoother and more responsive experience when switching between applications.
❓ Is the 15W charging speed on both phones sufficient for quick top-ups?
15W charging is relatively slow by today's standards. Both phones will take several hours to fully charge from 0%. However, the Moto G Power (2021)'s more efficient chipset means you'll likely get more usable battery life from a shorter charging session compared to the Galaxy M21s.
