What's the difference between battery capacity and battery life?
Published
What's this about?
Battery capacity often plays into battery life, but an impressive capacity stat doesn't translate to excellent battery life.
The one-panel cartoon

A high-tech meeting room with a large touchscreen display showing the battery capacity statistics of various devices, while a visibly exhausted-looking executive holding a tablet with an alarmingly low battery level sits slumped in a chair, his device plugged into a charger.
Caption: Impressive battery capacity doesn't guarantee you'll make it to the end of the meeting.

Editor's note
Battery capacity is like a car's fuel tank size, but battery life is about how efficiently you drive. A bigger tank doesn't guarantee a longer trip if the car guzzles fuel like there's no tomorrow.

Panel 1
*Setting: A cluttered workshop with a prototype smartphone on a workbench. Alex, an optimistic inventor, is holding a large battery with a surprised look on his face.* Sam (leaning over the workbench, rolling his eyes)
Alex: Guys, I've got a battery that can power this phone for days! This will change everything!
Sam: You sure it doesn't just explode first?
Panel 2
*Setting: A living room with Sam, the deadpan pragmatist, sitting on a couch while Robin, the chaos catalyst, is holding a phone with a low battery icon flashing on its screen.*
Robin: So, this battery is amazing, right? I can just leave my phone plugged in for a week and never worry about it?
Sam: Oh, it's amazing. Just not in the way you think.
Panel 3
*Setting: A dimly lit coffee shop. Alex, Sam, and Robin are gathered around a table with coffee cups. Alex looks crestfallen, while Sam and Robin share a knowing glance.* Sam (deadpan)
Alex: But... my battery lasted a week in the lab!
Sam: Yeah, but the 'lab' was plugged into the wall.
Robin: And real life is full of Netflix and social media, which eat through your battery.
Alex: Ah, right. Back to the drawing board, I guess.
