My one complaint about the Apple Watch Series 4 hardware

apple

There are plenty of things I love about the Apple Watch Series 4’s hardware: its thinner profile, its faster processor, and (especially) its larger screen.

What don’t I like? I really only have one gripe: battery life.

Based on my few weeks of use, the Series 4 has noticeably worse battery life than its predecessor. I rarely cracked the 50% barrier after a full day wearing the Series 3. With the 4, however, I’m often down to 40 or even 30 percent by day’s end.

That anecdotal evidence jives with more measurable figures; according to Apple itself, the larger Series 4 has 16.5% less battery capacity than the comparable Series 3 model. Presumably, Apple shaved away battery volume in order to produce a thinner aluminum enclosure. Honestly, I’m OK with that compromise. After all, the Watch still easily makes it through a busy day.

However, the decreased battery life does degrade my Watch experience in at least one way. In the past, I could set the Watch on its charger when I climbed into bed, and by the time I would get sleepy, it had fully charged. That meant I could slip it onto my wrist before drifting off, use it to track my sleep quality, and still wake to more than 90% charge.

Alas, that’s not possible anymore. It’s rare that the Series 4 has reached 75% charge by the time I get drowsy. I either have to (a) forgo sleep tracking altogether or (b) don the Watch for sleep and start the new day with handicapped battery life. ■
