Well I have the 3800 ext battery pack, on the package it says to get the most out of it it needs to be charged & discharged 3-5 times. So far it came with 50% battery life which was a good sign ( that's the way it should come). After charging the battery over night for the first charge it was at 100%. I then did e-mails ,sms, videos on the web, watched a movie that I put on the Pixi, talked my head off, took 112 photos at my family's picnic, I also played Pandora for about 3 hrs. I used the sprint nav for an hour. I mean I really did a lot with this phone from 8am til 12:30midnight. And the left over charge capacity was at 71% I was amazed and that was only after the first charge. I have been trying to really drain it down but that will take alot of usage=like with the navigation on all the time. With no photo's taken and just watching web videos and surfing the net, talking, sms, e-mail and installing ringtones and other apps I end at 86% batt life left. I've been starting my day with the cellphone on at 8am and off by 12:30midnight ...I must say this 3800mah battery pack sure does rock.
THE BACK COVER...it is made of an flexible thin plastic but it's tough strong, it matches the black glossy finish of the Pixi original finish. It also snaps on good I mean really good that it's kind of hard to get off. Insted of running your finger nail around the edges after pushing the button in, just push the button in and hold it in (use a pen), lift cover up at the corners of the center button it will take a little force but it will come off and it will snap back on really good. I had it off and on about 12 times and no signs of snap wear (it's really on good
but still don't drop your Pixi :
) With the new cover your phone will be thicker it will take the Pixi from the original 6.7 to almost an inch, which I like because you now have a better grip on the once was thin slippery cellphone. The xtra thick cover makes it easy to hold, text,dial,get and remove cards, and slide open & close your Pixi with just one hand and your thumb. The speaker holes on the back cover are not as many as on the original cover which IMO muffles the sound some...( JUST A THOUGHT for an easy fix just drill them out if you want to hack your back cover (just remember to go over the edges with a black sharpie pen).
And the pouches that I have found that will fit your new muscular Pixi are for the Blackberry 8300 and Nokia i 730 cellphones ( I'm sure there's more out there). The one I have is for the BB 8300 it's made by Cube, it's a nice snug fit and with a little strech of the pouch your new thick Pixi will fit nicely. the only down fall to a pouch is that it will muffle speaker sound for the ringer and hinder the effects of the vibrater...easy fix that I did, cut out a nice neat hole in the pouch with an x-zacto knife, box cutter, or small single edge razor in the same location as where your speaker will be.
All in All I like the new 3800 battery pack and back cover.... it's like the new Chevy Volt, as the Beetles song says.... I can go for miles and miles. And yes a holster is needed.
