An earlier post on the next Nexus phone is here.
One of the first things I look for is the screen size, because I read a lot. At 5.9 inch, Nexus 6 will be a giant phone. Incidentally, HTC One Max has the same screen size. A phone of this size will be difficult to hold. I would have preferred a maximum of 5.5 inch. May be reading experience would be better.
That reminds me: When Galaxy Note (now referred to as Original) hit the market end of 2011, an enthusisatic sales guy tried his best to make me buy one. But I found the screen size of 5.3 inch too big. I even remarked to that guy, who would buy such an huge phone!
In Jan 2013, at one of the elctronic stores, when I saw the same Galaxy Note, I was surprised seeing the size of the screen. I asked the sales guy, "Is this really Galaxy Note, the original one?" (By then Galaxy Note 2 was in the market.) He said, yes. I thought the size of the screen looked smaller than what I thought it was. Of course, it was just perception. 5.3 inch in 2011 was huge. The same 5.3 inch in 2013 looked quite normal.
So, though now I think the Nexus 6 screen size of 5.9 inch is huge, may be I will have to revise my opinion a couple of years later, when most phones would be of around 6 inch!
Nexus 6 will have top resolution of 2560x1440. LG G3, Oppo Find 7 and Samsung Galaxy Note 4 have similar resolution. Galaxy S5 has 5.1 inch screen with display of 1920x1080. Galaxy Note 4 has 5.7 inch screen.
Another spec that I look for is the processor. Nexus 6 is rumoured to have Qualcomm Snapdragon 805 chipset, and will pack 3GB RAM.
Some other features are: 13-megapixel rear camera with optical image stabilization and a 2-megapixel front camera. The battery will be a 3,200mAh one, and it's said, a mere charging of 15 minutes will give it a life of 8 hours. That sounds simply unbelievable.
Like HTC One M8, Nexus 6 is rumoured to have front facing stereo speakers.
But the best part is it will run on Android's latest operating system, now called Android L, the successor of Kitkat. That will kickoff the Android 5 version.
The launch of Nexus 6 and Android L is said to be in a couple of weeks, in mid-October.
Now, we just wait for more clarity on all these rumours.
