Apple Watch 4 users willing to upgrade to Apple Watch 7 may benefit from reading this analysis between the Apple Watch 7 Vs Apple Watch 4. Apple Watch 7 was released in November, and we are seeing accelerated deliveries of the new Apple Watch 7. Is it prudent for an Apple Watch 4 user to upgrade to the Apple Watch 7 smartwatch? There are interesting answers to this question. There are feature additions on the new Apple Watch 7 that catapults the watch as a premium health tracking watch. Let us study the differences between an Apple Watch 7 and an Apple Watch 4 to see what has changed between the two watches.
Processor and Device Storage- Apple Watch 7 Vs Apple Watch 4
Apple Watch 7 has an S7 SiP with a 64-bit dual-core processor. It has a W3 wireless chip and also a U1 chip (Ultra Wideband). The wideband is supported in specific regions that provide integration with the wideband technology. An Apple Watch 4 has an S4 SiP with a 64-bit dual-core processor; W3 wireless chip. It does not have the U1 wideband chip. Understandably, there are differences between an Apple Watch 7 and Apple Watch 4’s processors.
Apple Watch 7 has 32 GB internal storage and an Apple Watch 4 has 16 GB of internal storage. Device storage has doubled and comes in handy to download and play music files right through the watch’s device storage.
Screen and Display Resolution – Apple Watch 7 Vs Apple Watch 4
An Apple Watch 7 has a 45 mm and a 41 mm model. An Apple Watch has 44 mm and 40 mm smartwatch variants. The new design of the Apple Watch 7 also means that the size of the bezel on the watch has been reduced. This has allowed adding to the screen area of the Apple Watch 7. Notably, the screen size of an Apple Watch 7 is 1.9″ and that of an Apple Watch 4 is 1.78″.
The display resolution on the Apple Watch 7 is slightly better. Apple Watch 7 has a display resolution of 396 x 484 pixels while the Apple Watch 4 has a display resolution of 384 x 480 pixels. To the naked eye, the display resolution difference may not be apparent between an Apple Watch 7 and an Apple Watch 4.
One noticeable difference between an Apple Watch 7 and Apple Watch 4 is that the Apple Watch 7 is nearly 25% lighter than an Apple Watch 4. Apple Watch 7 weighs 38.8 g and an Apple Watch 4 weighs 48 g. Apple Watch 7 is sleek and more compact than an Apple Watch 4.
Apple Watch 7 also boasts of a crack resistant front display crystal, a feature that has been introduced for the first time on an Apple watch.
Heart and Health Monitoring – Apple Watch 7 Vs Apple Watch 4
Apple Watch 7 carries an ECG app and measures your heartbeat continuously. Perpetual heartbeat monitoring helps in sending alerts of a high or low heartbeat. Atrial fibrillation issues can also be uncovered using continuous heart monitoring. Apple Watch 7 rides on a third generation optical heart sensor. An Apple Watch 4 covers ECG app, high and low heartbeat alerts, and cases of irregular heart rhythm. The difference, however, lies in the fact that an Apple Watch 4 uses a second generation optical heart sensor. Aside from that, heart monitoring has not changed much between an Apple Watch 4 and an Apple Watch 7.
Blood oxygen saturation monitoring is available on an Apple Watch 7. It has a blood oxygenation sensor that would help you see the SpO2 saturation levels. Apple Watch 4 does not have any blood oxygenation sensor, and hence it cannot be used for SpO2 monitoring.
Apple watch 7 monitors your water intake; Apple watch 4 does not measure your water intake. An Apple Watch 4, on the other hand, tracks the weight of your body. Apple Watch 7 cannot track your body weight. So, there is essentially a tradeoff between the two watches for weight and water intake monitoring and tracking.
Multisport Mode – Apple Watch 7 Vs Apple Watch 4
Apple Watch 7 is more useful for tracking multiple sports activities on the go. It has a multisport tracking mode that allows capturing exercise and activity details when you move from one activity to another without any delay. Triathlon players would find the new multisport mode handy in calculating the total exercise time and activity on an Apple Watch 7.
Cadence Sensor – Apple Watch 7 Vs Apple Watch 4
Apple Watch 7 includes a cadence sensor that can help in monitoring cycling activity or workout. Apple Watch 4 does not have any cadence sensor and cannot be used for measuring cycling activity.
Battery life – Apple Watch 7 Vs Apple Watch 4
Apple Watch 7 and Apple Watch have a battery life of 18 hours. An Apple Watch 7, however, offers fast charging. You can go from zero to eighty percent battery charge on an Apple Watch 7 in 45 minutes. The full charge does take a full two hours, just like it would on an Apple Watch 4.
Fast charging on Apple Watch 7 seeks to browbeat the limitation of poor battery life on Apple Watches. You still need to charge every day. Nothing changes in that respect. But, you are back in business in less than an hour. That’s what makes Apple Watch 7 a compelling buy in 2021 and 2022. The hassle associated with daily battery charging remains unchanged, but the hassle has reduced by a few degrees.
Expectedly, an Apple Watch 7 has a few features that are missing in Apple Watch 4. These differences are highlighted for your ready reference below:
- faster processor,
- more internal storage,
- blood oxygenation monitoring,
- multisports mode,
- bigger screen,
- fast charging,
- cadence sensor.
Aside from these differences, nothing much seems to have changed between an Apple Watch 7 and an Apple Watch 4. The decision to upgrade from Apple Watch 4 to Apple Watch 7 will depend on one or more additional features that may be used on a new Apple Watch 7.
