Anyone know of such a thing..? As there isn't a larger capacity battery available for the N7 (afaik) I'm wondering if anyone knew if there is a suitable case with built in battery. I know there are rechargeable battery packs available, but I really don't want to be carrying around extra bits of kit if I can help it. For normal usage I'd say the N7 battery is better than average, but I commute a fair bit & any more than the odd half hour of gaming here & there and some viewing of HD content takes huge chunks off my battery. I've tweaked things as much as possible (custom rom etc) to help save battery, but this only goes so far. Thanks.
