Apple iPhone XS Max 256 GB in Space Gray Unlocked Cell phones & smartphones

Just purchased this item off of Mercari for my son and was not as described. I’m unable to use the item. So reposting

**Previous seller installed a new aftermarket battery. May have been installed improperly or could be a bad battery. Please ask Questions prior to buying so everything is clearly understood**

Phone looks great. Comes with case, screen protector installed, and generic charging cord.
