Xperia Z3

Dear Sony. We're excited about the upcoming Xperia Z3 smartphone. But to make us *really* excited, we have a few requests. Here are six great things we want to see in the Sony Xperia Z3. (For more on the Xperia Z3, read: Sony Xperia Z3 release date, price and specs: New Xperia smartphone due within months.)

1. Things we want to see in the Xperia Z3: A thinner, lighter, stronger

This is tough on Sony, which with Z1 first popularised the idea of a dust- and waterproof smartphone. But the nature of smartphone consumers is that we always want more. And the case of the Zperia Z3 is no different.

Rumours suggest that the Sony Xperia Z3 will be equipped with a metal frame. And if such online chatter is to be believed this will include a PVD coating that creates an attractive mirror-like finish. It should look like stainless steel, but be much firmer and lighter. And these are all things we like the sound of.

We're happy for Sony to stick to the Xperia model of big oblong handsets, but we want the new one to both thinner and stronger. So please, Sony, make the Xperia Z3 more able to deal with accidental damage from bumps and scrapes that is the already robust Z2.

2. Things we want to see in the Xperia Z3: Faster, more powerful - but with two day battery life

Yup, give us something good and yet we still want more. The Xperia Z2 is one of the fastest of a superfast breed of smartphones that are on the market right now. In truth the pace race for mobile tech has plateaud, and despite what the benchmarks will tell you all top-level smartphones perform just as well as they need to. But as we start to do more with our smartphones it would be great to have a phone that could handle multiple simultaneous computational and networking tasks. Even better one that not only lasts all day, but doesn't need charging every day.

Rumours suggest that the Xperia Z3 will be faster and more powerful than its predecessor, with a 2.5GHz Qualcomm Snapdragon 801 processor, 3GB of RAM and Adreno 420 graphics. So, Sony, make sure the code is sufficiently tight to avoid battery drain, and pack in a massive battery cell. Especially if the display is as good as hope...

3. Things we want to see in the Xperia Z3: Quad HD and curved display

The LG G3 and Galaxy S5 Prime have set the benchmark, and now Sony must follow.  Mustn't it? Most Xperia Z3 rumours suggest that Sony is set to concentrate primarily on performance, and will stick with 'only' a full-HD display with the Z3. But we hope for something more. After all, what's the point in having a great big phone like a flagship Sony Xperia if it doesn't come with a great big screen.

4. Things we want to see in the Xperia Z3: A better camera

This is no criticism of the Xperia Z2's camera, which is its outstanding feature - a 20.7Mp camera with pulsed LED flash. But the rumour that excites us most is that Sony may improve the camera further in the Z3. We're hoping for a 23.7MP camera, with ultra sensitivity to dim light and the ability to capture in 4K. We've also read rumours of optical image stabilisation and a 6x optical zoom. Want.

5. Things we want to see in the Xperia Z3: Android 4.5, or even 5.0

We expect the Z3 to arrive in September this year, superceding the Android 4.4 KitKat-running Xperia Z2. The Z3 will run Android of course, but the question is: Android of which flavour? The Xperia Z3 could arrive with Android 4.5, Android or Android 6.0. Android 6.0 is nothing more than a rumour, but we expect that the Nexus 6 will launch soon with Android 4.5. And Android 5.0 should launch this year. Could it be that the Xperia Z3 will launch with Android 5.0? Hope so. But if not please make it at least an Android 4.5 device.

6. Things we want to see in the Xperia Z3: A cost of no more than £550

When Sony launched the Xperia Z it had an SRP of £549. The Xperia Z1 launched at £599, and the Xperia Z2 was £559.

More importantly you can buy the Xperia Z2 for anywhere between £500 and £550. The market is more crowded than ever with good, high-end devices. And notwithstanding all of the above, the Xperia Z3 will have to be outstanding to, well, stand out. And to compete with the now excellent mid-range Androids it will have to be something special. But also it will have to be priced correctly.

If the Xperia Z3 costs more than £550 it will be a very tough sell. Do us a solid, Sony? (See also: Sony Xperia Z2 vs iPhone 5s comparison review: The David and Goliath of smartphones.)
