The longest battery life for the dedicated products in our review is the Levana Lila, which ran for 12.75 hours in full use mode. The manufacturer claims this unit will work up to 72 hours in power saving mode, but we only tested the monitors in full use. The Infant Optics DXR-8 came in second place with a shorter run time of closer to 11.5 hours. The Motorola MBP36S earned the lowest score for battery life with a runtime just under 7 hours. While not necessarily a deal breaker, there are plenty of other reasons to dislike the Motorola MBP36S, and the battery life is just a small part of a disappointing overall picture (no pun intended).
We tested and compared 9 of the most popular video monitors in this review using a comprehensive series of tests with continued use over several months. Our tests were designed to provide you with the information you need to make an informed decision on which product is right for your family and needs. Each monitor is scored based on performance experienced during our hands-on, side-by-side testing process. The test results determine the metric scores, and those scores combine to create overall scores and rank. Metric scores are derived from our in-house lab and user experience "in the field." Overall scores were weighted with a preference for the range, video quality, and sound clarity.
The features we focused on were those we thought either increased the performance of the monitor or made it more user-friendly for parents and increased the odds of getting good quality sleep. We looked for monitors that have sound activation that keeps the parent unit quiet when the baby isn't crying, so parents can potentially fall asleep faster because they don't have to listen to white noise. Some of the monitors were so loud, even at low volumes, that the white noise might keep light sleeping parents awake; this defeats the purpose of having a video product to begin with. We also liked the models with screens that automatically "wake" and/or go to sleep.
