This picture might explain the Galaxy Note 7 fires

When Samsung first recalled the Galaxy Note 7, it had suggested that the high-capacity battery it shoved into the smartphone was being pinched in such a tight space. Newer batteries used in the second iteration, built by another manufacturer, were supposed to be safe. Turns out they weren’t. What’s going on?

A new image posted by Arter97 —  a user who is well known in the CyanogenMod and XDA community – to Twitter suggests that the edges of the battery inside the phone are “too round” causing contact points to bend into one another. This is far from official, but it does align with Samsung’s message that the battery was short circuiting. A short circuit can occur when electricity flows along a path it isn’t supposed to, which is exactly what would happen if the contact points on the battery were touching one another.

Why this matters:

The Samsung Galaxy Note 7 was canceled after units continued to catch fire around the globe. The battery has been blamed for most of the issues, though it’s apparent something else is also going on. Samsung is still investigating the cause so we won’t jump ahead of its final word. The image above might give us a glimpse into what’s going on, however.

Thanks Jeff!
