found this post while looking for anker battery selling points and I have to say, what a ridiculous post.
We're talking sensation here. and by the looks of the size of that battery then at least the battery cover should be torn. Considering said cover is solid metal where the battery is the phone should most definetly be damaged. No ss to back up it's either damaged or not. No story to back up your claim, ony "phone was fine doing nothing in normal conditions". I'm not buying that. A certified battery doesn't xplode doing nothing, it had to be stressed somehow.
I think the following; the picture shows a messed up battery on a pavement (a bit of shoe is vissible). I'm guessing you either found this thing on the street, took a pic and thought it would be cool to troll XDA with some weak argument. Or you toyed with a loose battery.
In either cases, you didn't expect the XDA community to actually think this stuff through before buying this crap and flame a generally well praised battery manufacturer. GL on your next troll attempt, which is clearly not on XDA.
