Only had my V4 Rally 6 weeks, tried a Sygic a couple of times. As some says, it makes your phone hot - and with this, the battery drain! Roughly 1% per mile is my experience all 3 times - that is no good! I’ve got an IPhone 14 Pro Max, so had expected much better battery - and due to the size it won’t fit in the phone compartment, so not really easy to charge via the built-in USB port. Disappointed- but still love the bike and can still use my TomTom
