Just wanted to take a minute real quick to express how happy I am with my purchase of the Droid X extended battery. I got because I was making it about 80% through my day before having to give it a little juice, unless I used it sparingly. Now with this, I make it morning to night easy no matter my use. And, I use my phone heavily. I thought though, I wonder how long this would last if I used it only as much as I needed (well, what *I* consider need, heh) and left out all the non-essential stuff. I took it off the charger at 5:30am Monday. I'm at 15% now. I will at the very least make it till 5:30pm today, making it 84 hours. I may make it till I crash. (I'm going to it blinks red). 15% Uptime: 143:41 Since last hooked to charger: 3d 10h 26min (Mon 5:30am - now) Battery Mode: Nighttime Saver Battery: BH6X from local store. I have used my phone for everything I have needed. Every day. Plenty of texting, gTalking, and phone calls. Especially yesterday (found out we're having a boy!). I've read email, both gmail and my work email through the browser. I've checked up on sites (cough here) when I had to, but that was only a couple times. I've used the camera and sent several pictures. Plus other stuff, but this is what I do regularly. Every day. I have NOT browsed the web for the sake of browsing, been on youtube, streamed music or spent any time in the market (have updated apps though). No Maps, Nav, etc. I have not.. just hung out on my phone.. like I tend to do. I've not killed any tasks or background stuff. I've used it as much as I've wanted with what I mentioned above, being careful to quickly turn off the screen as soon and as often as I could, and leaving brightness on low. This wasn't a "how long I can go" test, it was a "how long will it last with me just using it for what I need to use it for" test. I would have been happy to make it to the end of Tuesday, and here it is the end of the workday on a Thursday. That coupled with the fact that the battery is hardly ANY bigger at all - I'm very happy with the purchase and felt the urge to share. Also, I love my X. Sorry for the rushed and all over the place post, kinda in a hurry. Edit: After the first reply I checked display time. Display usage is an hour and a half. So, clearly the Phone Idle and Cell Standby dominated that one. I wonder how long I could go with straight display time. Sounds like my next test!
