[Verizon Droid Charge] Serinety:
There has been much confusion and frustration surrounding our battery life and these custom roms. Some of us have great battery while others are having horrid problems.

I am writing this guide in the hopes it will help all of you with problems getting that great battery life.

This is a guide written from my own experience and technical understanding.

First, Your phone should drain, on average, 1% per hour or less while in standby mode (screen off). If you are not getting this average, you need to calibrate your battery.

ALWAYS flash a new rom with your phone at 100% battery - no exceptions!

i know some guides say to run battery down to 2% and then charge, but i never had much luck with this.

1) Before you flash your rom, charge your battery to 100% with the phone ON.

2) Once it says fully charged, turn the phone off and plug it in and wait for the on screen display to say 100% (this will take 5 to 10 min)

3) Turn the phone back on, and plug it in and charge till it says 100%

4) turn off the phone and charge again while off until the on screen battery indicator says 100% (again this will take 5 to 10 min)

5) repeat steps 1 thru 4 as many times as you feel comfortable, I recommend at least twice (I do it 3 times)

6) when you are satisfied with the charge, and the phone is still OFF with the indicator saying 100%, unplug the phone, remove the battery, and place the phone in download mode (hold vol down and plug into the PC)

7) flash your package (this is done in odin with the battery removed)

8) The first boot after the flash needs to be into Clockwork Recovery, wipe battery stats at this time (most roms will boot into recovery automatically, if not, boot into recovery manually)

9) after you have wiped your battery stats, wipe cache and other data (if the rom you are flashing requires this, if not, skip this step)

10) Boot the rom to the homescreen.

11) from this point on, you will use your phone like normal until the phone completely shuts off. this SHOULD take a while. you should see improved battery life during this stage. If not, dont panic, just run the battery down until the phone shuts off

12) once the phone shuts off (try to time this to happen at bedtime) plug the phone in and allow it to charge in the OFF position

13) once it is at 100% again, use the phone like normal and enjoy your new battery life.

IF YOU ARE DOING THIS WHILE NOT FLASHING A NEW ROM

Do steps 1-4 as many times as needed, I recommend at least twice, i do this 3 times

on the last charge up (your phone should be off while charging during this step) unplug the phone and boot directly into recovery and wipe battery stats. then proceed with the rest of the guide.

TO TEST THIS

charge to phone to 100%, try not to mess with it for an hour or so.. (light usage at most) you should still be at 100% or 99% after an hour. If you are at 95% or below, then the calibration has failed. (unless you have been using the phone or are in a very low to no signal area).

this calibration method is crucial to good battery life. Before I started doing this i was getting very bad battery life. Click on my username and look at my previous posts.. you will read about me *****ing badly about my battery, this is what I did and it has worked amazingly well.

I hope this helps

I combined a lot of techniques ive seen in other threads and some websites and then created this technique which seems to work really well.
