Just ordered the anker 4400mah battery for £9.99.
Normally I'm not a fan of extended batteries as they make the phone look stupid but I decided to give it a try anyway. I've been searching for a side by side comparison picture for size compared to stock( pictures of the handset with the battery in) but haven't been able to find any.
