Why the iPhone Doesn’t Have a Thicker, Bigger Battery ➝

Rene Ritchie, writing for iMore:

It sounds great in theory, but if you take an iPhone 6 as thick as the iPhone 4 and start to imagine how heavy it would be, you can start to see where it breaks down.

Apple was deliberate when they pointed out the iPhone 6 was actually lighter than the iPhone 4. They did that because, while thinness is nice and certainly improves the feel of the phone in both the hand and the pocket, it’s lightness that matters. Lightness improves usability.

Rene also notes a few interesting facts about batteries like their propensity to hold heat and their lack of radio transparency.

Tesla Motors Announces Powerwall ➝

Powerwall is a battery system designed to store energy for homes, companies, and utilities. The batteries can serve as backup systems during blackouts, store solar energy to be used during peak hours (when energy costs are at their highest), or allow owners to live completely off the energy grid.

The batteries will ship later this year and come in two models, 7kwh for $3,000 and 10kwh for $3,500

Apple Battery Charger ➝


On Tuesday Apple released an unexpected new accessory, a battery charger. The new charger comes with six rechargeable batteries and costs $29. The recharger is designed in the style of Apple’s other power adapters and works with any international adapters or extender cables that you may have already purchased for those other power adapters.

The new accessory is competitively priced when compared to other battery chargers and happens to draw ten times less energy during standby than the industry average.

I don’t have a whole lot of gadgets that use AA batteries — most of my devices feature built in rechargeable batteries. However, my household recently purchased a Nintendo Wii and with it a set of rechargeable batteries from Energizer for all those Wii remotes. It’s a little annoying that Apple decided to release this just a couple of weeks after I buy an ugly and much more power hungry recharger, but I guess I am happy that the Energizer battery charger that I purchased tells me how long until my batteries are fully charged. I’d still rather have purchased the Apple recharger but I’ll make do for now.

Also, why can’t any other company design batteries that look this good?
