I think we have a problem with the apps getting bigger and doing more things. They use more resources and drain the battery faster. We have batteries bigger than ever, but still mobiles don't last for a day. I would want to go back when the apps only did one thing, nowadays we have a lot of apps and they do a lot of things, even when you are not using them directly. So obviously the battery goes away very quickly. GPS on -> let's track the position, Wifi on -> let's synchronize everything, etc. Permission system should prevent this but it is not working when them we add those functionally to a library that doesn't require those permissions. So, it doesn't matter which smartphone you will use, the duration of the battery is linked with the apps you have installed. That is why most comments here are about disabling things and uninstalling apps.
