Apple Watch Series 3 Battery Life: Essential Testing Insights

Hey there, tech enthusiasts! We’re diving into the hot news surrounding the latest Series 3 Apple Watch. Scheduled for launch on the 22nd, this gadget is bringing something we’ve all been waiting for: Cellular and LTE connectivity. This means that, without your iPhone by your side, you’ll still be able to make calls, send out messages, get directions, use third-party apps, and chat with Siri—all just from your wrist.

Cellular Features of Series 3 Apple Watch

The beauty of LTE on the Apple Watch Series 3 is that it works seamlessly even when your phone is out of reach, unless you choose to turn it off. In fact, for music lovers, there’s an added treat. From October, the GPS + Cellular model will let you stream songs from Apple’s massive library of 40 million tracks.

Battery Life Concerns

A big question on everyone’s mind is about the battery. Without any visible changes to the size or battery capacity compared to its predecessors, how will it hold up? Well, Apple has shared some insights from their testing.

Apple’s Battery Testing Results

  • The Series 3, whether it’s the GPS or the GPS + Cellular version, can still average 18 hours on a single charge by their calculations.
  • This includes 90 time checks, 90 notifications, 45 minutes of app usage, and a half-hour workout with music playing via Bluetooth throughout an 18-hour period.

Detailed Battery Test Findings

For those who crave more specifics, Apple has broken down some numbers based on single-task tests:

  • Phone Calls: Expect around 3 hours if tethered to your iPhone, and just 1 hour using Cellular.
  • Audio Playback: About 10 hours when using Bluetooth, though streaming Apple Music hasn’t been assessed yet.
  • Workout Use: Around 10 hours if paired with your iPhone, 5 hours just on GPS, and 4 hours on both GPS and Cellular.

The challenge? While offering fantastic connectivity perks, the Series 3’s GPS + Cellular model might not be best for long-distance runners or those interested in extended GPS tracking due to battery constraints.

Upcoming Tests and Reviews

We’re not stopping there. We plan to run thorough tests on the Series 3’s battery life ourselves to confirm and extend upon these initial numbers. Here’s a sneak peek at what our experiments will include:

  • Comparing 38mm and 42mm models in the GPS + Cellular category
  • Switching between Cellular disabled and GPS-only configurations
  • Focusing solely on messaging functionalities
  • Workouts while having the continuous heart rate monitor off
  • Juxtaposing Series 3 GPS + Cellular with Series 2 and Series 1 models
  • Stacking against similar fitness trackers

If there are specific battery tests you’d like to see conducted, leave us a comment, and we’ll try to incorporate your suggestions in our reviews.
