Why does it seem like iPhone battery is better then andeoid?

Like even though the android has a bigger battery it seems like like the iPhone lasts longer in every aspect. Why is this?

1: iPhones have a much smaller screen.

2: Android have a higher resolution screen to power (my almost 2 year old GS3 has a higher resolution display than the iPhone 5S). The higher the resolution, the more battery drain.

3: Android has true multitasking. Once you leave an app running, it'll stay on that app until you close it out. Apple doesn't have true multitasking. It only gives you a list of what apps are running, but will refresh it the moment you open it up again.

4: Apple only uses apps and doesn't have more complex homescreen additions like widgets. Widgets can actually drain more battery if you have your homescreen added with only widgets. Android can also add lockscreen widgets depending on what Android version you have (if you have at least Android 4.2.2 or higher).

5: Android uses more animations (you can disable this of course), but as a default setting, Android has always had more animations enabled by default.

Personally, as a whole, I see that both iPhone and Android still need a charge by the end of the day. Hope this helped.

Its because the iphone design and hardware is better. Ever wonder why games are so much better on iphones even though the "so called" hardware stats should say differently? The same is true with battery, there's alot more to it then just size. Actually the battery life isn't even close, iphone far outperforms it especially a year or so down the road.
