Garmin Forerunner 735XT (Smart Watch / Fitness Tracker): 3.7 out of 5 stars from 20 genuine reviews on Australia's largest opinion site ProductReview.com.au. The Forerunner 735 XT has a huge range of apps that it can connect to. Garmin Connect is the standard and natively supported app, which can be used to store and view a wide range of data from activities, and also upload and plan routes and workouts. This is done via bluetooth, or the charging cable. The Forerunner 35 also offers mechanical buttons, making it easier to quickly and accurately control the device during a workout. Another significant benefit is battery life. The Forerunner 35 can last up to nine days without charge, while most smartwatches with a color display require charging every two days. The 735XT’s battery life for its Smartwatch and Ultratrac™ modes goes up to 11 days and 24 hours respectively. The 745 only reaches 7 days and 21 hours for those same categories but holds a strong 16 hours when in GPS mode, while the 735XT only reaches 14 hours. I actually brought a Garmin watch to several dive watch repair shops, and all refused the job as they said they could not guaranty the seal. I exchanged an original Garmin Swim that leaked for a refurb, and even that leaked right after the warranty expired, so user caution. My current 735xt refurb is 7 months old, and holding strong. The bright and punchy screen does mean battery life has dipped slightly, but Garmin has still done very well here; the Forerunner 965 is able to power around 6-8 days of relatively heavy training Battery Life after Latest Upgrade. I've had my 735 for about 1.5 yrs and I am suddenly experiencing battery life issues. I did a 68 mile ride the other day, and the battery only lasted 4.5 hrs which means it ran out before I finished. Today, I ran for 2:35 and it was down to 23% at the end of the run - and it was fully charged at the start. For the most accurate estimate, complete the user profile setup ( Setting Up Your User Profile), and set your maximum heart rate ( Setting Your Heart Rate Zones). The estimate may seem inaccurate at first. The device requires a few runs to learn about your running performance. Run for at least 10 minutes outdoors. After your run, select Save. J6Q9n3W.
