GPS use can often put a big strain on battery life, which could be particularly problematic in markets where people are using lower-end or older devices. Privacy aside, the idea of always-on location sharing may be unappealing for other reasons as well. That may sound creepy, but WhatsApp says it's a "simple and secure way to let people know where you are." It's end-to-end encrypted and users can end the location sharing before the designated time period is over if they want.

Previously, the app had a location-sharing feature, but it only allowed users to share a static spot on a map.
