That's not the issue. If you buy a Tile with a non-replaceable battery, the actual battery life will vary greatly depending on various factors: how long it was sitting on the shelf before you bought it, the temperature of the environment it's located, how often you make it ring, etc. 11 months after activation, the Tile app constantly blasts you with warnings that you need to "Re-tile" and buy a replacement: via email, app notifications, repeated non-dismissable (only "snoozable") in-app alerts, and a lot of doom and gloom UI that presents a false sense of urgency. The truth is, the battery can last 2 or even 3 years sometimes, and you don't need to be notified by the app when it's dead - you'll know it's dead when it shows up as "not reporting status" despite you knowing where the tile is. So you should be able to tell the Tile app "Yeah, I know it is near end of life, stop bothering me about it" one time, rather than the app acting insane and showing constant notifications/red warning labels/etc.
