Yes it is down to software and how optimization works for battery life. The Galaxy S3 stock battery 2,100mAh was terrible and even the extended 3,000mAh battery doesn't do that well so it can be down to optimization. Sony and HTC have managed to get battery life and software optimization sorted as many say the Z2 and HTC One M8 have great battery life. But for a phone with a 720p screen the battery is still too small with all that power under the hood

Well, like I said, at least is user replaceable by the looks of it, which is a big plus. The iPhone 6 and the z3 compact will most likely have sealed batteries.
Its a good looking device for sure.. they've done a good job

The battery is certainly small for even for 2012 standards where we crossed into +2000mAh territory, that is also my biggest concern on this phone, but when you consider what sort of consumer they are after with the Alpha, they won't be very heavy users like us, the battery life won't be earth shattering but it should handle a day.

The thing is that the cpu is also a octa core which means that the power under the hood is only used for heavy stuff for lighter tasks the A7 cpu's are used
And the other thing to rememeber is like tsepz said most people are not power/heavy users like Bono so there is every chance that the battery should be fine. Also in regards to GS3 that had a 2012 cpu (40 nm if i am correct) the current cpu's (28 nm and less) are definetely more power eficient
Btw speaking of ios iphone 5 had a terrible battery life after the upgrade to ios 7 -which is not the case with the iphone 5s . That proves as well that the newer technology is more poser efficient

To further add to your point Aussie, the Galaxy Alpha's CPU has been unveiled, it's a whole new Exynos5430 built on Samsungs 20nm process, not even 28nm
so it's even more power efficient than any other chip currently available, that could explain why Samsung went with a smaller battery.
Samsung unveils the 20nm octa-core Exynos 5430 processor
Samsung made the Galaxy Alpha official yesterday, and apart from being the first metallic Android smartphone from the Korean manufacturer, the Galaxy Alpha is also the first to be powered by Samsung’s Exynos 5430 SoC. Today, Samsung has released details on its new mobile processor. As expected, the Exynos 5430 is an octa-core chip (with four Cortex-A15 cores clocked at 1.8 GHz, four Cortex-A7 cores clocked at 1.3 GHz, and the Mali T628MP6 GPU), but it’s distinct from existing Exynos chips as it is the first to be built on Samsung’s new 20nm process, which the company says offers up to 25 percent less power consumption compared to SoCs built on a 28nm process while not compromising on performance.
The Exynos 5430 also supports big.LITTLE HMP (Heterogeneous Multi-Processing) processing – in simple terms, this means that all the eight cores of the processor can be active at the same time, and can also be individually turned on and off as and when required. Furthermore, the Exynos 5430 supports display resolutions of WQHD (2560×1440) and WQXGA (2560×1600) – the Galaxy Alpha might have an average resolution of 1280×720, but it looks like Samsung’s newest Exynos chip won’t be left wanting for power on high-resolution devices (it’s too bad the Galaxy Tab S is powered by the older Exynos 5420, resulting in a somewhat laggy experience.)
Samsung hasn’t published full specifications of the latest Exynos chipset, though you can hit up the source link for all the official details that are available as of now. Before someone asks, we should point out that the upcoming Galaxy Note 4 will be powered by the Exynos 5433 processor, and the Exynos 5430 will likely be reserved for devices that fall a tad below Samsung’s flagship phones and tablets.

All this just makes me more excited for the Note 4, this means it's Exynos chipset will be very efficient compared to what's currently available as most other manufacturers are either stuck with the Snapdragon 801 or 805 for their devices being announced at IFA.

^ That's awesome.. is it the first phone to use the 20nm ?
That should bring down the power drain from the CPU quite a bit so 1800mah might be perfectly fine for most people.

Hopefully Sammy knows what they're doing and that means we might have come to a point where smaller batteries give the same batterytime that we are used to from larger batteries.
Looking forward to the full review from GSMarena

Here is another review of the Galaxy Alpha I found it on the rumours page. They claim the device nothing special for the price tag.

Great news on the CPU inside the Alpha, fingers crossed it is as good as Samsung say at being energy efficient and if it gets anywhere near 70 hours on GSM arena's battery test (the S5 scored 72 hours) then it is a massive victory for Samsung and the Alpha. In an ideal world however (possibly in the Note 4) we will see that CPU in phone with a massive battery and see how good it really is when faced with a much larger QHD display, that is something I can't wait to see as the Note 4 is and as always shaping up to be a real beast.

I agree but in these modern times, the Alpha will be taking loads of selfies and Instagram pics so I do think the battery will drain quickly because most of the power is used by the screen. Anyway, I'd like to see the next Note with this design language but with a different material on the back. I'm wondering how the rumoured Apple phablet will be in comparison since it'll be the first true Note competitor.
