WHOOP 5.0 problems: what real owners report

Most common complaints

• 10×Owners upgrading from the 4.0 feel let down by the subscription model, unable to carry over old bands, facing renewal/upgrade fees, and several have canceled outright calling it extractive or a scam
• 10×Heart rate accuracy during exercise is significantly off versus Garmin, Apple Watch, Polar, and the Fitbit F8 -- readings run 20-30+ BPM low during strength training and spike erratically (180+ BPM) from arm vibration while cycling
• 8×Calorie burn and step counts read far lower than Garmin, Strava, and Oura for the same activity -- some owners report Whoop crediting roughly a third of the calories other trackers show
• 7×5.0/MG software update is draining connected iPhones' battery dramatically faster than before, with some seeing a full charge gone in under 10 hours
• 5×The bicep band itself can flip, slide up the arm, bunch, or fall off entirely for some wearers, requiring frequent readjustment to stay in place
