As anyone who has gone or thought of going down this route knows the disadvantages of a longer life battery is a bigger battery! I use my phone at work a lot and find i was having to lug around my charger with me all the time as the battery wouldn't even last to the end of my 8 hour shift i then had to keep half charging it as i had to unplug it to go home battery technology like lithium ion may have improved a lot from years ago but i was always told that to keep half charging a battery or changing a half drained battery would kill it eventual. If i am wrong then please correct me on this but that is how i try and run my battery empty completely then full charge. as soon as i have received it i will report back. To my second point has anyone seen any good case that might fit a slightly porky desire? I am told it adds about 5mm to the thickness and as nearly all cases on eBay are a good fit (or at least look that way) i feel sure that it would not squeeze in. Any help would be well received thanks.
