I want to make this thread the go to place to fix your battery problems.

It has come to my attention that many people have battery problems including my self. While searching the forums for answers I found many good tips but most were vague and not newbe friendly, not to mention they are buried deep down in the many rom threads, most with 50+ pages.

I do not have all the answers so I am going to have to rely on the more experience members of the fascinate forums that have dealt with these issues. this is where you come in, If you know how to fix battery problems PLEASE POST and

give detail instructions and or explanations

. I will update the OP with this info. This should help many people save time and might help devs, as many people tend to shout "battery life sucks on X rom" with out trying to get to the real issue.

We still need to resolve these issues:

The auto-rotate issue that hogs cpu at ~15

So go ahead and explain away, and thanks.

if you have battery problems post the question and hopefully someone can help.

How to reconditions/calibrate your battery

There is a lot of discussion on the "correct" way to recondition an a battery, to be honest I am not 100% sure what is the best method. All methods are very similar, if MY method did help your battery life, you can try landshark68 article over at Android Central forums.

do not bump charge your phone, Lithium-ion is not design for this and it can degrade the battery.

1- Charge phone to 100%

2- wipe battery stats by

1- If you are running super clean 2.9+ go to terminal (app, found in market) and type su, hit enter, bstats, hit enter. This will wipe battery stats and reboot

2- if you have any other rom, find out if you can erase batt stats with CMW (not all roms have this working properly so ask). Reboot in recovery >>go to advance>> wipe battery stats

3- Use phone as normal until it it shuts itself off. Do not plug it in.

4- Turn phone back on, still unplugged. If it can't turn on that's fine. If it can turn on let it fully drain again.

5- LEAVE PHONE OFF. Plug the phone in and let it FULLY charge without interruption.

6- Unplug and turn your phone on. Enjoy your (hopefully) extended battery.

Problems sleeping?

It has been reported by users that there are some sensor issues in froyo that create wakelocks and prevent your phone from going to sleep even with the screen off. This results in your phone using more juice while its not in use, giving you worse battery life.

Sensors that have been identify are

1-Proximity sensor

How Do you know your phone is not sleeping?

First, you need to see if the phone is not sleeping. Spare Parts is the easiest method.

Spare Parts > Battery History > Other Usage

If "Running" is at 90-100% (Probably 99.9% or 100%) then something is preventing the phone from sleeping.

To figure out what it is, adb is the easiest. Run adb logcat > logcat.log with you phone plugged in and allow it to sit idle for 2-3 min, at least long enough for the screen to turn off and the phone to idle a minute with the screen off. Then, press Ctrl+C to stop the output and open up the logcat.log file. Search for Wakelock and make sure that everything that creates a wakelock also releases the wakelock.

Got a rogue app?

An easy way to find rogue apps that hog battery is the Wheres My Droid Power app. Doesn't use resources until you open it, and doesn't reset the usage log when you plug the phone in. Free on market.

Battery saving apps

Juice defender

I just bought this yesterday, I still dont know if it improves battery life, but I can tell you that it sounds promising. This app manages everything form wifi,data bluetooth, to how often your phone syncs. I will update with my thoughts in a week or so.

Here is a review, it is dated, the app now has a much better UI, one of the best I have seen on android.

Juice defender my thoughts

I have been using juice defender for a couple of weeks now and I have a say, it really has improve my battery life, I can leave the house with 70% batt and returns after a 10-12 hrs and still be in the 30s, compare that to me leaving for work with 100% batt and returning with a dead phone. The biggest battery saver is the ability to only allow data (sync of gmail, facebook etc) in intervals of 15min (customizable). This keeps the phone from connecting and wasting juice every time an app wants to connect to the net. if you know of a similar app, post and add your thoughts.
