Default [Q] Warranty sticker location?

Does anyone know if there is/isn't a warranty sticker or indicator of some kind within the DNA? If so, where is it located?

My original phone lost power at random and is unable to be turned on, nor do the charging lights turn on. I have a replacement on the way, and I planned on taking the hardware from the old phone and putting it in the new one to retrieve my data. However, I want to be sure that I am careful with the warranty stickers if they are lurking...

Thanks!
