It needs your phone’s antenna to be on the entire time it does this, and it usually puts a heavy workload on your device’s processor. Depending on how much data the GPS is retrieving, it can take more than 10 minutes to get all those streets, landmarks and navigation details from various satellites.

But the the biggest reason GPS is such a power killer is because it keeps your phone from fully entering into a sleep mode. The screen may be off while your GPS is on, but the juice is still flowing. Sleep mode is typically the silent savior of most phones’ battery life, and without it your device will be losing life at a faster rate than usual.

Although certain mapping apps like Google Maps do at least take some steps to stop the drain, those looking for some extended power from their device would be wise to ensure that their GPS for as long as they can afford.
