Ordered a pair of SmartTag+. Arrived, installed, and then noted that the black tag was at less than 6% battery. Grey tag was fine. Returned items and ordered replacement.
New pack of two arrived. Installed - new black tag shows less than 6% battery. Grey tag was fine.
Can't believe that two different two packs both contained already drained tags. Normal?
I'm having a similar issue with a black SmartTag+. The tag keeps reporting very low battery but when I remove the battery and use a battery tester it shows it is fully charged. When I reinstall the same battery, the tag will report fully charged for a few days and then it's back to very low battery. A friend of mine has two grey tags and one black one (all purchased at the same time) and he tells me he has only had to replace the battery in the black one. After reading your post I'm now wondering if this is a coincidence or not...
My first black ST+ died in less than six months. I just got a replacement and the very first time I turned it on it said the battery was low. I tried two brand new batteries right out of the package and it says the same thing.
I got two black smart tags less than a month ago. They now both read low battery 3%. I put in a new battery in one of them and it still says only 3%. Something seems to be wrong with the equipment. I am using a Samsung S22 phone.
I ordered a set of 2 SmartTag+ from Amazon, received 10/26/22.
Upon receipt, paired with phone & Smart-Things. Grey tag already showed low battery. Within a week status went to very low. Replaced battery rather than hassle with Amazon returns.
Today is 1/30/23, so ~3 month. Same grey tag shows very low and now black tag shows low.
I believe this info should be provided to all the review sites that recommended Samsung SmartTag+ over the competition. Either there's a basic flaw with the tags OR the devices were designed with batteries that were too small.
