Apple Watch SE Review: 30 Days Without an iPhone

Introduction

Most smartwatch reviews test a device alongside a phone. This one tried something harder: for 30 days, the Apple Watch SE replaced the iPhone almost entirely, with the phone reserved for a handful of unavoidable tasks like posting short-form video and viewing detailed running data. The verdict that emerged is nuanced. The watch is technically capable of standing in for a phone for most everyday communication, but software limits keep it firmly in companion territory. And as a running watch, it is good for most people, but not quite good enough for a serious runner who logs around 60 miles per week.

The Apple Watch SE as a Running Watch

Recent software updates have brought the workout app up to par with dedicated running watches. Data fields are editable, and the watch delivers pace, distance, heart rate, wrist-based power, elevation gain, and deeper metrics like ground contact time. Structured workouts beep automatically when it is time to run hard and again when it is time to recover, and post-run data is presented with all the detail a data-minded runner would expect. One quirk: the on-watch font will not win any design awards.

GPS accuracy proved solid over 30 days of testing. Apple never gives a clear signal when a GPS lock has been achieved, so you never quite know if you have a good fix, but measured distances were as accurate as any dedicated running watch. Some runs came in slightly short, others slightly long: a run measured at 18.44 miles on a Garmin read 18.12 on the Apple Watch. The frustrating part is that detailed data and sleep metrics require the iPhone app; they are not available on iPad or MacBook.

Daily Life Without an iPhone

As a daily driver, the watch handled more than expected. Texting worked, though dictation was unreliable and messages often had to be sent twice. Phone calls were fine, especially with earbuds in. Email was actually easier without a phone to mindlessly scroll, and responsiveness improved noticeably. If something is not available as a watch app, Siri can even pull up a regular website, which is not pretty but works in a pinch.

The limitations showed up outside the normal routine. Transit and ride-hailing were the sore spots: there is no watch app for the commuter rail, so buying a ticket meant going inside the station and dealing with a paper ticket. Uber and Lyft watch apps no longer work. And items in the iPhone’s Apple Wallet do not automatically transfer to the watch’s wallet, which meant no marathon bib QR code and no event tickets on the wrist.

Battery Life: The Biggest Trade-Off

Battery is the biggest annoyance of living with this watch. It does not really last longer than a day, and for someone GPS tracking a daily 60 to 90 minute run while also tracking sleep, there was no natural charging window. The solution was deliberate twice-daily charging: once after waking up and before the morning run, and again after getting back and showering.

That system worked, with one close call. At the Chicago Marathon, fully charged at the start and GPS tracking for just under four hours, the watch finished with 16% battery left, and that was without any music playback.

Verdict: Phone Companion, Not Phone Replacement

So is the Apple Watch SE powerful enough to replace your phone? Technically, yes, but its potential is limited by software. It is designed to be a phone complement, and that is what it does well. There was an unexpected upside to the experiment too: stepping away from constant scrolling noticeably weakened the habit, and leaving the phone plugged in on the counter instead of in a pocket helped keep it that way.

Buying Advice

As a running watch, the Apple Watch SE works for most people, but not for a dedicated runner. Charging twice a day gets old, and the touchscreen-first design is a problem for sports, especially in cold weather with long sleeves and gloves, where physical buttons are preferable. Sleep tracking and HRV numbers feel reliable, which is a genuine strength, but viewing that data requires the phone. Alarms, oddly, do not sync between watch and phone, an annoyance worth knowing about. For families, the watch makes more sense as a lightweight communication device for a child on a family plan than as a serious training tool.

If your needs lean toward communication, notifications, fitness basics, and sleep tracking, this is an easy watch to recommend. If you log serious weekly mileage and want buttons and multi-day battery, a dedicated running watch remains the better choice.

Conclusion

The Apple Watch SE is a capable companion device that can stretch much further than most people expect, covering calls, texts, email, payments, and solid GPS tracking. But software friction, wallet gaps, and battery life make clear it was never meant to go it alone. Buy it as the best accessory to an iPhone, not as a replacement for one.
