AMD's Trinity Removes Historical Battery Life Objections

AMD has been long perceived as providing less notebook PC battery life than its primary competitor, Intel. While AMD did score well

in specific usage models, Intel performed a better, particularly in modes where the system was idle or in sleep mode. Most of the de-facto battery life benchmarks heavily weighted idle times when the system wasn’t doing anything, so Intel typically came out on top with the benchmarks. With Trinity, AMD has finally remove this objection by significantly improving battery life in most usage models. By removing this objection, AMD is in a much better position to drive significantly more business than its predecessor, Llano.

Battery life for notebooks has always rated as a key purchase criteria for notebooks, right up there with screen size, price, weight and brand. It is more important for business users than consumers, which makes perfect sense given how much time is spent away from a power socket. Consumers are valuing increased battery life more and more as they are taking their laptops to different rooms in the house. Intel helped initiate and drive the technologies for low power notebooks with its Centrino-branded processors years back and has recently put the accelerator down with their Ultrabook initiative and Ivy/Sandy Bridge processors. Battery life isn’t just a spec for geeks. It is merchandised now more than ever by OEMs, ODMs, and retailers at the point of review, influence and most importantly, point of sale.

Significantly improved battery life isn’t just an AMD marketing talking point; it’s a reality and is proven out by multiple product reviewers over the last few weeks. AnandTech summarized it succinctly when he wrote, “It’s worth pointing out that the concerns about AMD’s battery life from a few years ago are now clearly put to rest. At least at the TDPs we’ve tested, AMD is easily competitive with Intel on battery life. “ The other product reviewers are echoing the same sentiment with different tests which gives me confidence that it’s reality, not hype.

Apple silently updates the iPad 2 battery life

If you thought the New iPad (third generation) stole the thunder from the second generation iPad, think again. Apple may have dropped the price on the iPad 2 making it the most desirable tablet yet but it has also added one feature that may just make it a little more desirable than the new iPad – better apple battery. The iPad 2 has not only seen a price drop to Rs. 24,500 for the Wi-Fi only 16GB model and Rs. 32,900 for the Wi-Fi +3G model, but the device has seen a new SoC as well. Dubbed the iPad 2,4, Anand Tech provides us with details of the device. The iPad 2,4 has a 32nm LP SoC as opposed to the 45nm LP SoC found on the previous iterations. And what does this upgrade mean to the consumers? Well two hours of better battery life for starters, the iPad 2 anyways clamed of 10-hours of battery life. In Anand Tech’s tests, the iPad 2,4 outperforms the iPad 2 and the new iPad by miles. So, how will you know that the iPad 2 that you picked up has the 32nm LP SoC? Well, the box is identical to any other iPad 2 box so good luck truing to identify it from the box itself. But, if the iPad is running iOS 5.1 then it is the new 32nm iPad 2. If it is running iOS 5.0.1, then it is the older generation iPad 2. You can also run performance benchmarks such as Geekbench, linpack and more to find out information about the SoC.

This particular iPad 2,4 sample came from Best Buy, and several attempts to find one elsewhere came up short. All indications seem to point to the iPad 2,4 being relatively rare, which makes sense considering what's inside it. Although the iPad 2,1 and its 3G brethren all used a 45nm Apple A5 SoC, the iPad 2,4 uses a die-shrunk 32nm version. The performance remains the same, but the die is much smaller. This isn't however just a normal die shrink, as Apple is using Samsung's 32nm high-k + metal gate LP transistors for this new A5 die. Intel was first to make the HK+MG transition back at 45nm in 2007 and correctly predicted that no one else would make the move until 32nm at the earliest. Transistors are amazingly complex to fully understand, but at a high level they're quite simple. Imagine a transistor as a silicon based switch. When on, current flows, and when off, current stops flowing. The smaller you make a transistor, the more likely it is to misbehave. If current flows while the transistor is off, you waste power. This is known as leakage current and can come from a number of sources.

HTC One X battery life tests prove fruitful

We’ve been writing a lot about the HTC One X as this flagship smartphone for HTC has impressed a lot of people. Famed for its Tegra 3 quad-core processor (Snapdragon S4 dual-core for the US), one of the main concerns about this phone was whether the battery life would live up to expectations. News today tells how HTC One X battery tests have proved fruitful, which probably means even more people will rush to get their hands on it. The HTC One X is packed with decent specs but the downfall of many otherwise excellent smartphones lately has been their battery performances. As we are increasing data use with our phones and are now seeing cutting-edge specs such as quad-core processors, high-resolution displays, improved cameras and the latest software many of us have found that our phones cannot get through an average day’s use without the smart phone battery draining. Motorola recently addressed this issue by taking one of its successful handsets, the Motorola Droid Razr, and bumping it up with a larger battery to become the Motorola Droid Razr Maxx. So how has HTC done battery-wise with the HTC One X? It seems the manufacturer has actually done very well indeed. Engadget tells how HTC is applauding itself following testing on the HTC One X. The company has issued a blog post pointing out that people who have tested it have had praise for the htc battery life. Its own tests took place on the international version with quad-core processor rather than the dual-core AT&T variant for the US and seemed to show glowing results. HTC explains that the HTC One X shows a 147% performance increase in talk time over one of its previous handsets, the HTC Sensation. It also shows a 39% increase in video playback time compared to the Sensation, a 105% improvement in MP3 playtime and a 23% increase in Web browsing time. Anandtech (who carried out independent third-party testing) was apparently impressed with the battery life of both of the HTC One X variants but Engadget tells how although they were satisfied with the dual-core HTC One X (even with LTE enabled), they were less satisfied with the global version. Some hot batteries: CANON FS100 Battery, JVC BN-VF707U Battery, JVC BN-VF808 Battery and more, brand new with 1 year warranty. It does appear though that HTC has been taking consumer concerns over smartphone battery performance seriously and the company points out that its engineering teams have spent thousands of working hours on the Battery Stamina Boost Project for the HTC One series of phones. It seems as though there’s yet another aspect worth recommending about the HTC One X then and so far we’ve heard very few complaints about this device, which is still to see a US release. What are your thoughts on the HTC One X and its battery performance? Do you already have the international version and if so, how have you found the battery life? Maybe you’re waiting for the us variant and news of these battery tests has made up your mind that this is the right phone for you? Let us know with your comments.
