Great impoves phone.
Great battery after full days use the battery always shows about 50% still left. Just flown to Monaco for day, used phone all day and watched 2 films on plane and battery lasted from 2 am to 11pm. Whilst the battery makes phone heavier and thicker I think it improves the feel of phone and makes it easier to hold. I keep phone in belt pouch "Dura Gadget" and it still fits in it. I will never change back to standard battery. Buy this if you rely on your phone working.
