I had been using 5.5 inch android phones and it lasted few days without charging. Then I switched to Iphone 6 plus and drains the battery in 24 hours.

Because they suck

Screen size doesn't dictate battery capacity.

It hit home for me.

Fun fact, the iphone's battery is less than, yup, 1500 mAh. That's really really small, considering the average battery life is about 2500 mAh. That's a whole 1000 mAh less than the average android smartphone. Then there are phones, such as the xperia z3, which boasts a very amazing, 3100 mAh battery life for 24 hours of continuous gaming, streaming, browsing, etc. That's why iPhones are so bad when it comes to battery life, cause 1, they are very very small, 2. They die of faster than normal batteries, so they lose charge faster and faster every month. And after a year, your iPhone is stuck to the wall forever (of course, the statement is exaggerated, but you know what i mean, iPhones are just constantly charging, it's kinda funny watching them scramble finding charging ports and chargers) So yeah, that's why your iPhone is draining battery so fast, they've made the phone so slim, that the battery capacity is worse than one of those key flashlight batteries.
