*IMPORTANT* The results of this have been mostly positive. Although we aren't having problems now, we may run into a few bumps later on as this solution is very premature at the moment. Please do not put your hopes and dreams on this solution just yet until we have more time to play with it. -------------------------------------------------------------------------- I may have found a solution and you'll only need to do this one time (hopefully) For most of who got the EVO's a bit later, we had the update that fixed the SD card issue. All was great so most of us most likely did not do a format on the micro sd card. I tried to make my battery last longer by doing all these tips and tricks and the one that helped most was the turning off and charging it over n over again. It's a pain doing that so i figured what else haven't we tried? I charged my phone to 100% and decided to take the micro sd card out and just play with the phone. I noticed that my battery didnt drop 10-15% in a matter of minutes so i thought that was weird. I decided to format the micro SD card (the slow way) and now i notice that when I'm at like 90% and i start charging, it takes a lot longer to charge up to 100% . When i take off the charger, my battery doesn't drop anymore. Can anybody confirm this? Format was 32kb, and unchecked "quick format'. Formatting on a Computer Step 1 Insert the tiny micro SD card into slot located at the bottom of the the larger SD card adapter. Insert the combination into a USB card reader or your computer's onboard card slots--if available. Step 2 Open the "My Computer" menu and then insert the card reader into a USB port on your computer. Note the drive assignment your computer gives the reader when inserted (ex F:Card Read ). Step 3 Right-click on the drive your card is inserted into and choose the "Format" option from the menu that appears. Click the "Start" button at the bottom of the "Format" menu. Taken from: How to Format a Sandisk Micro SD Card | eHow.com edit: Ive been charging my evo when it hit 90%, it's been 25 minutes and its at 98% and still charging. edit2: It's been 15 minutes since i hit 100% and i'm still at 100% battery life. with moderate usage. edit3: it's been 37 minutes and i'm still at 100% edit4: it's been 42 minutes, 100%. edit 5: 43 minutes, 99% battery, 37% android system, 20% standby, etc etc. Not bad for using the phone for so long such as messaging and e-mails. edit 6: Right now i'm at 83% battery life at 8H 35M What i did so far since 99%: 4-5 Text messages 25 Minutes of Youtube video on my own wifi 1 Minute of checking forums Check both my email accounts (I cycle through this only once a day) Took 6 camera pictures with no flash edit 7: I charged it back to 100% (It took some time to charge from 90% to 100%). The reason why i'm charging back to 100% is because this format fix is to only address the 10-15% loss of battery life. So here i am, i'm at 100%, no rebooting or anything of that matter. The 100% still sticks and is running smoothly! I for one will shout out to the world that the format of the sd card fixed my 10-15% loss of battery life issue. edit 8: Some people have reported that it works, some reported that it doesn't. Try if you have nothing to lose. Note that a lot of people are still testing this and problems can arise later on in the future. In the meantime, the ones that got this to work haven't ran into any problems just yet. We'll see how this works out as it plays out in the next couple days. Also, i wanted to thanks for all the feedback.
