Earlier this week, I walked through a great collection of iPad, iPhone, and Mac products that I’d strongly recommend. Today, I’m here to help you choose an excellent spare battery for any portable Apple device. You can trust me because I’ve been testing Apple batteries for over a decade, conducting hours-long tests to learn how each new Apple device consumes power, and how quickly each battery replenishes a given device. If you want to learn more about why I’m recommending the specific batteries below, I discuss key factors worth considering at the bottom of this guide.
Have you ever wondered how much of your battery is being used? Or have you ever wondered why sometimes when you use certain apps your battery dramatically drains? New in the iOS 8 Settings application is the ability to track battery usage per each app you have installed on your device. This method is very similar to tracking your cellular data usage. Read more
Apple has apparently enabled much faster battery charging in the newest iPhone models, but you’d never know it if you only use the included power adapter. According to a change in the iPhone 6 and 6 Plus discovered by iLounge, both of the new smartphones are equipped with the hardware to support 2.1A charging.
The problem? Apple only includes a 1A charger in the box. If you’ve been using that AC power adapter to recharge your phone, there’s a much faster way to do it. Since the iPad has long supported 2.1A charging, you can grab a charger for the Apple tablet and use that to achieve a much quicker charge.
Another way to benefit from this new capability is to plug your iPhone directly into a newer-model Mac, which will charge it at the appropriate speed. iLounge noted that the Macs tested for this feature were running Yosemite with no mention of OS X Mavericks, so it’s possible that the change may require the upcoming OS, which is currently is public beta.

A report from the Daily Mail over the weekend claimed Apple is working with fuel cell company Intelligent Energy on a project that hopes to embed fuel cells in mobile devices “within a few years.” The Daily Mail doesn’t exactly have the best track record when it comes to accuracy, but the report claimed “senior sources in the US” have confirmed the partnership between the two companies.
The technology could be rolled out in devices such as laptops and iPads, allowing them to run without being charged for days or even weeks…Intelligent Energy revealed upon floating that it bought a bundle of patents in tandem with a major ‘international electronics company’…It has kept the identity of its partner a closely-guarded secret. But a source, who has knowledge of the partnership, confirmed that Apple is the big name working with the Loughborough-based firm.
The report noted that Intelligent Energy already has ties to Apple with former Apple Computers product specialist Joe O’Sullivan sitting on the company’s board and a new office in San Jose not far from Apple’s headquarters in Cupertino. Read more
An innovative approach to solar charging revealed in an Apple patent application published today (via Patently Apple) could make it more practical to power both MacBooks and iOS devices from the sun.
The voltage and power generated by a solar panel varies with the amount of sunlight. To turn the power supply into something that can safely be used by an electronic device, you need a converter or regulator to deliver the correct specs to the device, adding cost and bulk to the panel.
What the Apple patent describes is building the necessary power management circuitry into the MacBook, iPad or iPhone so that it can accept whatever power the panel supplies. This potentially allows for cheaper and more portable panels … Read more
NVIDIA announced a new series of notebook GPU’s today branded as the 700M series. Introduced today are five new graphics cards in total, and NVIDIA said they would be available in a long list of laptops over the next few months. The five new graphics cards include two options aimed at the “mainstream segment”, the 720M and the 735M, while the remaining three, the 740M, 745M, and 750M, will be “for the performance segment” of the market.
The graphics cards are being touted by NVIDIA to “maximize performance and experience,” but they also more power efficient than their predecessors. Because the 700M Series is notebook-only, expect these to be less powerful than a desktop version of the 700 Series that may be announced sometime in the future.
Helping our new 700M chips reach such lofty levels of performance is GPU Boost 2.0, a GPU innovation that extracts every ounce of available computing power from the graphics processor. Before GPU Boost, GPUs were held back by synthetic benchmarks that pushed chips and power usage to the limit, far beyond the levels typically seen when playing games. This ‘worst case scenario’ forced us to throttle GPUs, leaving spare performance on the table when playing games.GPU Boost resolves this problem by monitoring power usage and temperatures, enabling the GPU to use every last ounce of performance without exceeding safety or comfort limits.
While the press release from NVIDIA said the new GPUs will be available in nearly every notebook maker other than Apple, it is possible these GPUs will be seen in the next-gen MacBook Pro with Retina Display. The current 15-inch MacBook Pro with Retina Display sports a NVIDIA 650M GPU, as does the high-end 21-inch iMac model, so an upgrade to the 700M series only makes sense.
The full press release is available below.
New NVIDIA GeForce 700M GPUs Squeeze Every Drop Of Performance Out Of Notebooks, Automatically
Monday, April 1, 2013
NVIDIA today announced five new notebook GPUs which deliver a trifecta of technologies that seamlessly and automatically maximize a consumer’s notebook performance and experience.
With no effort or input from the notebook user, the technologies work in the background to save battery life, enhance performance and enrich the visual experience — providing the best notebook experience the GPU can deliver. They include:
New NVIDIA GPU Boost™ 2.0 technology, which intelligently adjusts GPU clock speed to maximize graphics performance.
NVIDIA® Optimus™ technology, which enables extra-long battery life by switching the GPU on and off so it runs only when needed.
GeForce® Experience™ software, which adjusts in-game settings for the best performance and visual quality specific to a user’s notebook and keeps GeForce drivers up to date.
“There is an elegant simplicity to NVIDIA’s GeForce 700M notebook technologies,” said Rene Haas, vice president and general manager of the notebook business unit at NVIDIA. “You use your notebook how you want, and GeForce makes your experience awesome.”
Incorporating all three of these technologies, the new lineup of NVIDIA GeForce 700M GPUs includes GeForce GT 750M, GeForce GT 745M, and GeForce GT 740M GPUs for the performance segment, as a well as GeForce GT 735M and GeForce GT 720M GPUs for the mainstream segment.
NVIDIA GeForce 700M GPUs are available today. Every leading notebook manufacturer will be introducing notebooks with GPU Boost 2.0 technology, including Acer, Asus, Dell, HP, Lenovo, MSI, Samsung, Sony and Toshiba.
