Below, we’ll evaluate the Forerunner 245 vs 945 in the following categories:

  • Battery life
  • Overall weight
  • Display

Battery Life

If you run long distances, you need a watch that won’t give out before the end of your workout. Long battery life makes it less likely that your watch will need a recharge before you do.

But many factors can influence battery life even within the same watch model. This is mostly dependent on what features you are using.

The Garmin Forerunner 245 has a base-line battery life of seven days. This assumes that you aren’t using GPS or listening to music. When you are using your GPS, for instance, the 245’s battery life shrinks to just 24 hours.

By contrast, the Garmin Forerunner 945 has double the battery life at a maximum of 14 days. When using GPS, this watch can run for a full 36 hours.

Regardless of the setting, the Garmin Forerunner 945 lasts longer. If you plan to take long runs, with your watch, the 945 will require fewer recharges than the 245.
