Battery life
It's not so much that tech companies outright lie about their products' battery life as much as they test them in unrealistic scenarios to get the figures they advertise.
Do you regularly use your laptop with the Wi-Fi off? Do you enjoy having your tablet screen permanently set to 30% brightness? Do you set your email to only download once an hour on your smartphone? Yeah, didn't think so.
