You also get an always-on mode, missing from the Charge 4. Fitbit also says it’s twice as bright, and will no doubt carry over the auto brightness feature seen in the last-gen band. The Charge 5 has the same pixel density as the Charge 4, but the larger display means there are many more pixels with which to render graphics and watch faces. It’s a 1.04inch display, and the 326ppi pixel density suggests resolution is around 260 x 170 pixels. While Fitbit has not released the full specs of this screen, we can calculate the rest from the stats it has given us. The Fitbit Charge 5 feature most will notice first is the color OLED screen, a feature that should arguably already have been in the Fitbit Charge 4. Saying, “hey, why don’t you try less hard to exercise” regularly is not very Garmin.

Garmin’s version is called Body Battery, but Daily Readiness seems to take a more active approach to its behavioural suggestions. This kind of exercise bandwidth calculation also found in other wearables. There’s no obvious technical reason Fitbit could not add it to the Fitbit Charge 4, but it seems the older band won’t get it, presumably because it will be phased out. Daily Readiness will suggest you go easy sometimes, perhaps trading that long run or intense gym session for something a bit easier.ĭaily Readiness is also coming to Sense, Versa 3, Versa 2, Luxe and Inspire 2. In a way this is the opposite of the “get up and get moving” alert most fitness trackers fling at you. This looks at your recent exercise, your heart rate variability and recent sleep patterns to estimate how worn out you are, and will suggest the sort of exercise you might want to take part in that day.

The Daily Readiness feature ties together the Charge 5’s fitness interests with the wellness side. You get six months’ access included with a Fitbit Charge 5. This is part of Fitbit’s wellness strategy, which ties into the nutrition, yoga and meditation content you can access as part of a Fitbit Premium subscription. And the whole process has a sort-of meditative lilt that will probably leave you feeling less stressed once it’s all over. This time it monitors for changes in electrical activity that suggest you are sweating more, and interprets these as a stress indicator.Īssuming this feature works as it does on a Fitbit Sense, you’ll be asked to wait for a couple of minutes as the Charge 5 does its thing.

Once again, you hold your digits to the panels and wait while the Charge 5 takes a recording. This uses the same panels as the ECG sensor. The Fitbit Charge 5 also gains the EDA sensor introduced in the Fitbit Sense.

Of course, that is not to say a very fast (tachycardia) or slow (bradycardia) heart rate isn’t necessarily a diagnosable condition in its own right. This is more about health than fitness, in a tracker context, as an abnormal sinus rhythm may be something to talk to a healthcare professional about.
