President Barack Obama has refused to veto a ban on Samsung products in the US.

Back in August the International Trade Commissions ruled a ban on the import of certain Samsung smartphones and tablets for infringing Apple patents.

The devices in the list include the Galaxy S 4G, Galaxy Tab, Galaxy Tab 10.1, Fascinate and Captivate among others.

The White House was given 60 days in which it could veto the devision, but it seems Obama has given the no-no.

Playing politics

"After carefully weighing policy considerations, including the impact on consumers and competition, advice from agencies, and information from interested parties, I have decided to allow [the ban to go ahead]," said US Trade Representative Michael Froman in a statement.

Apple found itself in the same situation in August but in a rare move Obama chose to veto the ban, arguing that it risked damaging competition in the US.

It's unlikely that this prove too damning for Samsung, given that its successful newer products, such as the Galaxy S4, aren't affected.

However it could still take the case to a US appeals court if it so wishes, so it might not be game over just yet.

We've got more rumoured info on the Nexus 5 – which means that now you should wonder what don't we know about the forthcoming Google superphone.

Well, there are a couple of new tidbits of just-surfaced info which we weren't aware of, concerning the differences between the two versions of the handset.

According to a source speaking to PhoneArena, each variation will be powered by a different capacity battery.

The 16GB Nexus 5 will allegedly have a 2,300mAh battery while the 32GB will pack a 3,000mAh variant. Oddly however, the leaked LG Nexus 5 manual we spotted the other day claimed the 32GB model has a 2,300mAh battery - the opposite of what we're hearing now.

The price is right

The same source also reports the prices of the models. Apparently the 16GB will be priced at $299 (around £186, AU$315) and the 32GB will cost $349 (around £217, AU £368).

A 3,000mAh 32GB model will certainly go down better with buyers, but it's just a shame that we won't be getting that 64GB variant we so wanted. Then again, this could be nonsense, so remain open-minded for now.

The Nexus 5 is expected to touch down this month and be the first device running Android 4.4 KitKat, which is going to excite those looking for the best vanilla Google experience.

There have long been rumours suggested that the Finnish smartphone manufacturer could be working on a tablet and now am intriguing link has been found on Nokia's website.

The tablet currently goes under the moniker Lumia 2520 and a search for this on Nokia's US site reportedly, until recently, offered up just one result - an FAQ defining what a tablet is.

While the FAQ itself didn't name check the Lumia 2520, there was clearly something linking the name to the page.

Adding more fuel to the fire is the fact Nokia has now "fixed" the peculiar search result, so if you go and try to generate the same thing you'll be out of luck.

From tablet to phablet

The Lumia 2520 tablet could well be announced at Nokia's Abu Dhabi event on October 22, where we expect to see the Nokia Lumia 1520 - which itself has seen more leaks.

A few new snaps claiming to show the 6-inch, quad-core powered Lumia 1520 in the wild via Chinese site Coolxap.

The leak didn't offer any further details as to the features of the smartphone, nor a Lumia 1520 release date, but TechRadar will be live at the Abu Dhabi event in a couple of weeks to bring you the news as it breaks.

LG Chem has announced that it now has curved batteries in mass production, which will fit in not only phones but also glasses and watches. The curved design makes them ideal for phones with the curved displays that LG and Samsung are currently working on.

But that's not all. The company has also developed a 'stepped battery', which it's already using to fill extra space in the LG G2. Essentially it adds a little hump, or 'step', to the battery which can fill empty space in the phone and give it a bit more capacity.

Twist and tie

Most exciting of all is its plans for a cable battery, which is exactly how it sounds, a battery in the form of a cable. It can be bent and even tied in a knot and it won't heat up during use. As intriguing as it sounds it's not here yet, as LG states that it will arrive in 'upcoming years'.

When it does arrive it could be a game changer, adaptable enough to fit in almost any device and perfect for flexible devices, such as smart watches, which could benefit from a battery that can bend during use.

Along with LG's curved displays it seems like the company really has a thing for products that bend, but if it means we can eke more life out of our smart devices then they can make a slinky battery for all we care.
