Let us know how you get on.
Batteries are a difficult one to claim under warranty (outside the manufacturer warranty) as they have a finite life and are known to suffer from poorer rechargeability over time (as indicated above). They are often considered a consumable item (have manufacturer warranties less than the rest of the product - a car is a good example). As they are consumables and known to often be the weakest part of devices, they should be replaceable.
If the battery can’t be replaced, this fits into the “Right to Repair” which is discussed elsewhere on this forum. One should also expect a $300 watch to last longer than the life of a battery (2 years), and as such as indicated by some of the above posts, could be a claim under consumer rights under the Australian Consumer Law.
Depending on the watch, it appears that the battery is replaceable. Model LM-W315 manual states:
Warning Notice for Battery replacement
- For your safety, do not remove the battery incorporated in the product. If you need to replace the battery, take it to the nearest authorised LG electronics service point or dealer for assistance.
- Li-Ion Battery is a hazardous component which can cause injury.
- Battery replacement by non-qualified professional can cause damage to your device.
So it does appear that the battery is replaceable in some LG smart watches (don’t know your watch model, but is likely it can be replaced). Hopefully the business you have found is able to replace the battery so that you enjoy further use of the watch.
Having a device that needs regular recharging often means that it won’t last as long battery wise as a traditional device where a battery may last many years between replacement. Smart devices do push battery life, along with apps and other things (GPS, Bluetooth, WIFI) which run in the background.
I have friends that have smart watches that they replace regularly (which I get the feeling is to keep up with the Joneses), but I am happy to stick with my 15 year old Seiko where the battery lasts around 5 years (and $30 for s straight battery change - more for a seal as well) be changes
