Data Screens and Customization

The 840 allows for data screen customization directly within the Garmin Connect mobile app. Changes made in the app automatically sync to the device, offering greater flexibility in data field selection. This simplifies the process of creating and managing custom data screens compared to the 830.

ClimbPro Enhancements

ClimbPro on the 840 is a notable improvement. The visual representation of climbs utilizes more gradient colors and detailed sections, providing a clearer picture of the upcoming challenge. This surpasses the 830's ClimbPro in terms of visual clarity and detail.

More importantly, the 840's ClimbPro automatically detects climbs, even when not following a pre-planned course. This proactive feature enhances situational awareness, unlike the 830's course-dependent functionality. This makes the 840's ClimbPro significantly more user-friendly and useful.

Solar Charging and Battery Life

The Edge 840 offers optional solar charging, extending battery life by up to 6 hours. While the benefit might be marginal in ideal conditions, it’s a useful feature for extended rides or those in unpredictable weather. The 830 lacks this solar charging capability.

The base 840 model boasts a 26-hour battery life, significantly longer than the 830's 20 hours. Even with the marginal solar charging boost, the 840 provides ample battery life for most cycling needs. The longer battery life adds peace of mind for multi-day rides or those who might forget to charge regularly.

Buttons and Physical Controls

The Edge 840 features four additional buttons compared to the 830, providing alternative controls when the touchscreen might be less responsive (e.g., rain, cold, gloves). This redundancy improves usability in various conditions.

While the 840's touchscreen remains the primary input method, the extra buttons offer a reliable backup. The buttons also cause a blue box to highlight selected elements which somewhat detracts from the clean interface. The 830’s reliance on touchscreen might be problematic in less-than-ideal weather conditions.

Size, Weight, and Charging

The Edge 840 is slightly larger and wider than the 830 to accommodate the solar panel and wider bezels, but screen size and resolution remain identical. This size difference might be negligible for most riders, but the 830 is slightly sleeker.
