Here's how 2014's flagships fare against each other with equalized battery capacity
The quest for better battery life will hardly ever cease to push manufacturers to try hard to boost their game in this so vital and most-appreciated department. Sure, we value big and sizable batteries as much as the next man, but isn't software optimization a tad more important that pure battery capacity? We decided to check out if this is truly the case by normalizing the battery capacity of some of 2014's most popular devices.
[battery life (min) ÷ battery capacity (mAh)] × average battery capacity = normalized battery life
What does the results listed below actually show us? It will show us how long would each tested device last if all had the same battery capacity - in this case, roughly 2933 mAh. Figuratively speaking, it's like putting different race drivers in one and the same cars for a 1-mile drag race - the only thing that matters will be the very driving skills of the racers and not the properties of their vehicles. Thus, we can easily see which manufacturers have succeeded in optimizing their devices and which have not. All in the name of science!
