If you want Samsung, The Galaxy J7 2017 might be good for you. It has a 13MP camera, in Antutu benchmark the phone have 46.000 in score and a 3.600mAh battery.
You will have less battery capacity than the J7, but you will have more score in Antutu (61.200 instead of 46.000) and more MP (16MP) than the J7 (13MP).
I think if possible get a Zenfone 3 Zoom. Has a Snapdragon 625 (reasonable performance, not fast but not too slow) but a 5000mAh battery making it one of the longest lasting phones that has a brand. Camera is up there with the good ones and Android Oreo is on the cards when Asus finally update it (guaranteed). I don't know how much it is but should be below 500 euros
Huawei Mate10 Lite. 300 bucks, 5.9", big battery, 18MP, I would choose it over any Samsung in that price category.
I have owned the iPhone SE since a month after it came out. The performance is top notch, mainly due to the fact iOS is proprietary and is custom tuned to each device for optimal efficiency and performance. On the flip side, Android is designed to run on as many devices as possible, so will never perform at max potential on any single device. Here's the Geekbench for your Galaxy A5: https://browser.geekbench.com/v4/cpu/6476427 And here for the iPhone SE: https://browser.geekbench.com/ios_devices/42 . As you can see, single core performance is nearly 5x as much and multi-core is much higher even with less cores. Battery life is also outstanding. Here's an article from Business Insider. http://www.businessinsider.com/iphone-se-has-amazing-battery-life-when-tested-2016-5 "But there's one area where it blows the iPhone 6S away: battery life. Users who are primarily concerned with battery life should opt for the iPhone SE over the iPhone 6S." The reason the Android phones always have larger batteries is because they always have been and always will be less efficient, due to reasons described in performance paragraph. I would absolutely choose the iPhone SE over the Galaxy S8, and I wouldn't even consider a last-generation low-end phone like the A5. I've been an owner for a year and a half, and I'm nothing but happy.
Yes, I actually was on the iOS 11 beta program even before it was officially released. I am now running 11.2.5, the most recent public channel version.
What is the use of the phone going to be? if you are a busy person i recommend http://techcheckdaily.net/wp-conten...-dual-screen-phone-first-look-xX31xYRl-II.jpg but if you are doing photography then maybe something else
But the problem with anything Apple produces is that they're laughably overpriced and after four years won't be properly supported anymore. Basically, you're forced to spend a grand on a new phone every three years for no reason other than feeling better about the fact that you might've just looked poor had you been seen in public with a $300-400 phone that will even though the OS is less efficient perform just as well in all the amazingly CPU intensive applications called Firefox, Youtube and Whatsapp. Tl;dr: Don't buy an iPhone.
