How do you use cell towers and wifi for location?
Go to settings. Press on Location and then on Mode. The middle power saving location mode option is WiFi and Mobile networks. It uses very little of your battery, even if left on all of the time. It avoids using the more power consuming GPS entirely, at the expense of a less accuracy.
For most purposes, such as weather apps or labeling your location on photos, this level of location accuracy is good enough.
When mapping where you are going, on the other hand, you better then bite the bullet and turn on the GPS for better accuracy. If your GPS is slow to lock onto the satellites (mine is), then select the top mode, which uses all three ( GPS, WiFi, and mobile communication) to get the best accuracy, most quickly. But this mode will use more juice.
