Phone price has become the most important thing to me. Now that we have re-sellers (aldi, amaysim) who can be 10 times cheaper than telstra, optus or vodafone I don't think it's worth going into a phone contract any more. So I look for phones that i'm comfortable buying outright.
I tend to agree with many of the other users that battery life is very important. You would hope the phone would last a day without charging regardless of how much you use it. I think my LG G2 goes flat quicker in remote locations than it does in the city. Does that make sense and should it be something choice should test for?
Second for me would be the quality of the main camera for photos and video. I have never taken prints of my phone photos so i suppose "quality" means something different to a quality from a regular camera. Full HD resolution is enough and focus, noise, and image stabilization is very important. The selfie camera on my previous phones was lousy so i tend not to use it although sometime i would like to.
16GB is enough memory for me now because I use music and video streaming services (spotify, youtube) and online photo backup (google photos).
Every phone i've used lately had good enough call quality and was loud enough (via the ear speaker). i was recently impressed with a HTC phone which had excellent sound quality via the external speakers (is that what their called?). The quality and volume was good enough that you would not need to use small external bluetooth speakers.
When you do your next review, please be careful not to get into a "megapixel competition". By that i mean, there's only so much you need in each feature after which more doesn't help. if the ear speaker in one phone is twice as loud as another phone it's not twice as good if the original phone was good enough. You may say that readers can choose what is important to them but the problem with that is we don't have a frame of reference so we will most likely ignore the lower rated product and never know it was good enough for us.
