Nokia today said that it has pared down the size of HERE Maps updates to reduce the amount of network usage.
Nokia offers offline maps for countries, states, and cities around the world. Individual maps vary in size, but many are more than 100MB. Downloading such large files is often impractical or not allowed over cellular networks. With incremental updates to HERE Maps, Nokia is now pushing only the new and updated data to its individual maps, rather than requiring users to re-download the entire map. Nokia says this reduces the size of most updates by 85-90%.
HERE incremental updates are being rolled out for all Windows Phone 8 smartphones with the latest firmware, which means Nokia Amber for Lumia devices and GDR2 for all others.
