A teardown performed by manufacturing company Instrumental suggests that the industry s ongoing obsession with slimness was the Note 7 s downfall.
Its report pins the blame on Samsung s aggressive design, claiming that the handset s battery was squeezed in too tight and wasn t afforded any space to deal with day-to-day pressure.
It notes that manufacturers tend to build 10% of extra space into handsets, as batteries swell a little when they re charged.
According to the report, Samsung decided against this.
Our two-month old unit had no ceiling: the battery and adhesive was 5.2 mm thick, resting in a 5.2 mm deep pocket, the report reads.
There should have been a 0.5 mm ceiling.
