SmartTag Battery Life sucks

[Obsydian]

So i have 3x standard Smartags so far never changed a battery in over a year, whereas my 2x Plus version barely last 2 mths.

How is everyone getting on with the Plus versions?

I have 2 smarttag+ have been on extensive travel (so likely pinging alot) only buy cheapy batteries, seem to last around 3-4 months ...

 I have 2 x SmartTag+ - they were a Christmas gift to me in December 22 - and I activated them that week. 

I have had one in my car from January to March - and I got the low battery warning. I changed the battery, but the one I removed still showed fully charge on my battery tester. 

The second one has never left the house - it just came up with low battery warning - the same - battery changed and removed battery showing full charge on battery tester. 

Batteries removed are iDE brand. I have fitted Energiser batteries - but in SmartTag+#1 the few weeks old battery is already down to about 60% and has not left the house. There is only 1 Samsung device in the house - my Galaxy Tablet. 

I bought another 2 normal SmartTags a few weeks ago - they still show 100%. 

What I cannot seem do do is register the tags for warranty - has anyone done this?

So I have just taken the iDE battery removed form the smartag+ which was showing low and red, and fitted it to a normal smartag, where it is showing 100%

I will keep an eye on it - but this seems very strange, The battery removed from the smarttag was manufactured by HenllMax I think it says.
