- Scenario 2: Regular phone use with high-intensity activities (gaming or heavy app use), values all day battery. Choose the Samsung Galaxy A15. Its better performance and vastly superior battery life is perfect for power users.
- Scenario 3: A mix of use cases with a focus on a modern experience. Choose the Samsung Galaxy A15 for its balance of battery life, performance and modern software.
My Choice
If I were choosing, I would personally lean towards the Samsung Galaxy A15. While the vivo V21 5G has a superior selfie camera and slightly faster charging, the significant advantages of the A15 in terms of battery life, newer software, and overall performance would be more beneficial to me on a day-to-day basis. As a regular smartphone user, the enhanced performance for gaming and general apps, along with longer battery life, is more valuable than a top-tier selfie camera. The better outdoor screen visibility is also important for me. Also, having a side-mounted fingerprint sensor is a small but convenient upgrade, and not having to worry about updates in the near future gives the A15 an overall edge.
