2024: Apple Watch Ultra 2 Review, Auckland, New Zealand. #drmobileslimited #applwatch #watchultra, #watchultra1,#watchultra2,#watchrepair

4th May, 2024:  Auckland, New Zealand.  Blog posted by @davidlim

Apple in September 2023 introduced the second-generation Apple Watch Ultra, a follow-up to the original Apple Watch Ultra that came out in September 2022.

The general level of GPS accuracy of the Apple Watch Ultra 2 errs towards excellent but is let down in precisely the circumstances where dual-frequency reception is supposed to give accuracy – nearby tall buildings and valleys.

What is different between Apple Watch Ultra and Ultra 2?

Apple Watch Ultra 2 vs. Apple Watch Ultra: What's new and ...

A new processor, an improved ultra-wideband chip, double the storage and a brighter screen — that's what the differences between the Ultra and Ultra 2 distill down to.

There's no ignoring that the Ultra 2 is a large watch. Coupled with the chunkier digital crown and flat display, it stands out a lot more than the Series 9. My wrist measures 152mm and even though the Ultra 2 looks hefty, it's surprisingly comfortable on a small wrist and I wear it all the time.

Designed for every kind of outdoor adventure in and out of the water, Apple Watch is perfect for hiking, biking, running, swimming, surfing, and those occasional water balloon fights. And with Apple Watch Ultra 2, you can snorkel, scuba dive, and freedive down to 40 meters.



Does Ultra 2 have ECG?


Sensors: Electrical heart sensor and ECG app. Third-generation optical heart sensor. High and low heart rate notifications.

Why does the Ultra 2 turn red?

Apple Watch Ultra 2 Review

This watch excels in accuracy, connectivity, and user-friendliness, though it's a modest upgrade over the first generation

Our Verdict

The Apple Ultra Watch 2 is our go-to recommendation for fitness enthusiasts seeking prolonged battery life and robust connectivity features in an Apple Watch. It's elevated by the user-friendly Apple Health app, which efficiently organizes exercise, sleep, and daily heart rate data. The watch's stylish design complements its vibrant display and a sizable 49mm case. However, the latest iteration offers minimal advancements, making an upgrade from an Apple Watch Ultra 1 largely unnecessary. Despite Apple's emphasis on ruggedness, its core strength continues to be in its smartwatch capabilities. Compare it to other top watches in our lineup of the best GPS watches.

The Apple Ultra Watch 2 continues to be the best smartwatch for athletes and those looking for longer battery runtimes in an Apple watch. If you appreciate connectivity and phone-like features on your wrist, we continue to recommend this model. Apple's Health app is also our favorite for viewing data and metrics associated with our runs, sleep, and daily HR tracking. We think it offers the cleanest design without feeling cluttered like the competition. The physical design is elegant and premium, offering a super bright display and 49mm case size. This updated model has little to offer over the previous version right now, but we expect this hardware to be more utilized in the future. We would not recommend upgrading if you already have a first gen Apple Watch Ultra.


While this is a great watch, it's not for everyone. Our priority in a GPS watch is battery tracking and on-screen data viewing while performing activities — both areas where the Ultra 2 falls flat. For less serious athletes, these qualms are likely overly critical, but we find this watch is often distracting and overly featured. Luckily, you can customize it to minimize features and distractions, but that would make us question purchasing this watch style in the first place. Apple's marketing emphasizes its rugged capabilities, but at the end of the day, it's an Apple Watch, and smartwatch features continue to be its strong suit.


Performance Comparison

Features

Receiving the highest rating for its feature set, there is little offered on the GPS watch market that you don't have access to with the Ultra 2. With an extensive set of both native and third-party apps, you can customize your experience to your liking. It's these features that make it possible to leave your phone behind, especially if you pay for a cellular data connection that will keep you connected. Regardless of your data connection, you can still access features like Apple Pay, downloadable music, SOS, and maps. The main change for this model over the first iteration is its updated chipset, which allows for new features like precision watch finding, on-device Siri, and a double tap gesture that activates the main function of any app you are in.

Red mode was previously one of our favorite additions to this watch, and now it automatically adjusts to changing light conditions. Recently, flashlights have been making their way onto GPS watches, which have quickly become one of our favorite features. While the Ultra 2 doesn't have an actual flashlight, the screen gets super bright and is the best screen-style flashlight we've tested, thanks to its peak 3000-nit brightness.

As mountain athletes, our feature priority continues to be based on the functionality of activity tracking. The Ultra 2, in our opinion, falls flat in technical terrain, with the greatest oversight being the lack of a descent elevation data field. We also prefer data fields that adjust based on the amount of available screen real estate. If you have a data screen with one field, that data should be oversized to fit the additional room, but the Ultra 2 keeps the field the same size regardless. The mapping/compass function is one of the better on-watch options, but we'd be hard-pressed to use this over our phone, especially considering the maps lack a lot of topographic terrain detail in most locations. The Ultra 2 continues to be the best option for those who desire features and performance in urban or less technical environments. For serious athletes in technical terrain, we'd opt for something a little more tailored to that environment.

Battery Life

This metric and its importance to you should make or break your decision surrounding the Apple Watch Ultra 2. With only roughly 12 hours of GPS tracking, ultra-endurance athletes may want to look elsewhere. Luckily, you can extend the life by turning on Low Power Mode, but still expect it to be limited over the competition. Pretty much every GPS watch we've tested has increased battery performance with a new generation, but not with this Ultra 2 upgrade. Users of other GPS watches will be surprised by the amount of charging that is needed to keep this watch alive.

Other watches, even cheap ones, can last weeks without charging, whereas the Ultra 2 can't even make it two full days without low-power mode. Compared to the premium models at this price point, the battery life found on this model is almost annoyingly short, and it seemingly requires constant attention to make sure the watch isn't going to die on you. Users that have Apple Watches won't see the problem as they are accustomed to the low battery times, but if you are looking to upgrade your GPS watch and haven't used an Apple Watch before, be sure to consider this. While low power mode is an option, don't let it influence your decision-making; if you decide this watch is for you, expect to charge the watch almost every day, especially if you plan on using GPS tracking in addition to all-day health tracking.

Power Tips and Tool: How to save battery life on Apple Watch SE? Dr Mobiles Limited, #watchrepair, #applewatch, "#watchultra, #watchultra2

26-4-2024: Auckland, New Zealand
Posted by @davidlim, #davidlim, #davilimnz




Low Power Mode prolongs battery life by turning off always-on display; limiting the mobile network and Wi-Fi connections of your Apple Watch; and disabling background sensor readings including heart rate measurements, high- and low-heart-rate notifications, irregular rhythm notifications and blood oxygen measurements.



Some steps you might want to consider:
Disable the Wi-Fi and WalkieTalkie on your Apple Watch. ...
Minimize Apple Watch notifications that are not useful to you. ...
Remove the apps that consume the most power from your Apple Watch. ...
Disable environmental sound measuring. ...
Turn off always-on display mode.

So we made sure we gave it a battery that lasts all day, too. Our goal for battery life is 18 hours after an overnight charge, factoring in things like checking the time, receiving notifications, using apps, and doing a 60-minute workout.

Can I leave my Apple Watch SE charging overnight?
The short answer is yes. Apple itself acknowledges that you can charge the Apple Watch overnight. The device fast charges from 0-80%, but trickle charges between 80-100%.

Should I charge my Apple Watch every night?
All Apple Watches and iPhones are designed to be charged all night every night on the recommended charger. Unless you are prepared to turn them off for long term storage, "making them last" more than a day actually uses more charge and will shorten battery health.

How can I increase the battery life of my Apple Watch?
Increase the battery life of your Apple Watch! Increase its autonomy so you can use it for longer. Just follow our tips and you're ready to go. Read on and we'll show you how to make your Apple Watch battery last longer.

Disable the Wi-Fi and WalkieTalkie on your Apple Watch
Two things that consume battery power are being connected to a Wi-Fi network and having your WalkieTalkie enabled. To disable Wi-Fi you have to go to Settings from your watch and disable it. For WalkieTalkie, you have to go to the App that has the same name and slide the switch so that it is not green.

Minimize Apple Watch notifications that are not useful to you
Another option to save battery is to only enable the notifications that you really need on your watch. That is, you can disable all the notifications from apps that are not essential on your Apple Watch, so they won't waste your battery.











Even with a healthy battery life in my device, I'm not sure when the problem originated and how it can be resolved. However, in my search to diagnose my own device, I found a ton of settings that can help boost your Apple Watch battery life, even if it's currently suffering under watchOS 10.

1. Turn off the always-on display
This is the most effective thing you can do to preserve your Apple Watch's battery life. While yes, it can be super inconvenient to ditch the always-on display, it can be the difference between your Apple Watch lasting all day and it dying before dinner time. I turned mine off for a weekend and was surprised to find that it greatly enhances endurance, albeit not to the point of pre-watchOS 10.

How to: On your Apple Watch, head to Settings > Display & Brightness > Always On, then toggle the feature off.

2. Use Low Power Mode when you can
I don't recommend using Low Power Mode all day since it limits the functionality of your Apple Watch, but in a pinch, it can squeeze out a lot more juice than you think. If you drop down to 40 percent by 2 p.m., your watch will last the remainder of the day without issue by using the feature.

3. Disable cellular connectivity
If you have an Apple Watch with cellular connectivity, it's best to not use your cell connection all the time. At times, depending on your location, your watch can go searching for an active LTE signal, only to spend too much time doing so and never grabbing onto one that's strong enough to preserve your battery. If, for example, you're traveling long distances or chilling at home, it's best to flick it off until you need it.
How to: Open Settings > Cellular on your watch and toggle off "Cellular." Then, when you want to turn it back on, flick the switch again. It's worth noting that airplane mode will essentially do the same thing, but it also turns off Wi-Fi which you need for certain things, so manually disabling cellular data will save some steps.

4. Turn off background app refresh
If you have a good amount of apps on your watch, chances are they're fetching data in the background so that they remain up to date. This, as you would imagine, requires power from the battery. If you're only using said apps sporadically throughout the day, there's no sense in having them locked and loaded 24/7–just refresh their data when you open them.
In my usage, turning the feature off hasn't made a huge difference for battery life, but it's enough to slightly improve endurance without affecting functionality all that much.
How to: Go to Settings > General > Background App Refresh on your Apple Watch and toggle the feature off.

5. Turn off irregular heart rate notifications
With some of the newest Apple Watches, Apple includes a feature that can alert you when your heart rate is beating in irregular intervals and alert you when it may be atrial fibrillation. While that's nice to have for tracking your health over time, it means the heart rate sensor is constantly on collecting your heart rate, which isn't good for battery life.

How to: Visit Settings > Heart > Irregular Rhythm Notifications and flick the feature off.

6. Reduce the amount of notifications you get
When a notification comes in, it not only plays a "ding!" to alert you, it also vibrates your Apple Watch and lights up the screen. While your notifications won't drain your battery in excess, if you get enough of them throughout the day, you'll definitely notice a difference in endurance.

How to: On your iPhone, open the Apple Watch app and navigate to "Notifications." From there, you'll be presented with a list of the apps on your phone that are sending notifications to your watch. Go through the list and turn off the ones you don't want to receive any longer. You also have the option to group notifications together if a particular app sends you a lot during the day but you want to keep them on.

7. Turn off Siri
Ah, Siri. Many people swear by the voice assistant and use it daily to do things like check the weather, start a timer (or two), play some music, or start a workout. But if you're like me (and, presumably, many others), you don't touch Siri at all on your Apple Watch, and it's just sitting there wasting your battery, constantly listening to hear that magical phrase "Hey, Siri." In other words, you should turn it off.

How to: On your Apple Watch, head to Settings > Siri and under "Ask Siri," choose "Listen For." From that list, tap the "Off" button. This will disable the mics and only let you trigger Siri by long-pressing the Digital Crown.

8. Factory reset your Apple Watch (a.k.a. the last resort)
I've heard from many folks who have faced issues with battery life on the Apple Watch that it's best to do a complete factory reset. Full disclosure: it's not going to work for everyone, but if you've exhausted every option on your Apple Watch to extend battery life, the battery is still healthy, and you don't want to upgrade, your best bet is to reset it and start from scratch. That way, you can set up your watch and, along the way, spot the app or service that drains your battery the most. It may also help clean up some of the system bloat in watchOS 10 that's led to poor efficiency on your watch.
How to: Go to Settings > General > Reset on your Apple Watch, then choose "Erase All Content and Settings." You won't have to disable Find My or get rid of your cellular plan since you'll be setting it up with your iPhone again, but if you want to get rid of absolutely everything, make sure you disable Find My and dump your cellular plan during the process.

Remove the apps that consume the most power from your Apple Watch
Similarly, a very practical way to save your battery is to reduce power-hungry applications. If you have several installed on your device, your battery will notice it. Only keep the apps that consume the least amount of power. You can even delete native apps that you don't use to minimize background battery and storage consumption.

Disable environmental sound measuring
The Apple Watch is in charge of our health, including our hearing. However, this check causes the Apple Watch to continuously measure the noise level of the environment you are in. Disable this option to save battery life. Go to Settings> Noise> Environmental Sound Measurements to turn this feature off.

Turn off always-on display mode
If you have an Apple Watch Series 5 or later, you have an always-on display. This screen ensures that your Apple Watch always tells you the time, even if you haven't turned your wrist. If you want to save battery life go to Settings> Display & Brightness> Always On and turn the feature off.
