Buying Guide: Key Purchase Considerations
- Battery capacity vs. efficiency: A higher mAh rating helps, but efficient processors and software tuning extend usable screen-on time.
- Display size and weight: Larger screens drain more power; pick a balance between readability and comfortable pocketability.
- Storage and RAM: Sufficient RAM helps maintain smooth multitasking; expandable storage protects against data constraints on long outages or trips.
- Network compatibility: Ensure the phone supports your carrier’s bands, including 4G/5G. Some models are GSM-only or region-specific.
