How To Improve Battery Life

[vi3tboiii54]

So to my understanding, you should be at 100% when you flash any ROM thats when the phone starts the whole reporting process all over again. Then it wouldnt be necessary to wipe bstats after starting up a new ROM?

Should be right.

Hey guys, I am pretty new to nandroid back-ups and I had a quick question. Earlier today, I charged my phone, turned off and charged, then charged, and ran the battstats in Terminal Emulator. My battery hasn't drained all the way so I haven't been able to do the full charge on it yet. My question is, will performing a nandroid back-up negate the bstats wipe, since I wiped the stats after my last back-up? Might be a dumb question, but I want to make sure I do the batt wipe correctly. Thanks for any input.

I don't think that was a dumb question at all. I think it was an excellent question that a lot of people will have.

This is a very helpful thread, newb but been doing alot of rom and theme flashing recently. Noticed today that my phone says battery is at 100 then when i unplug to use it reads in the 70s, so def not right. Going to try this process and see how it works. Thinking about juice defender as well, will that help with battery life after i finish resetting the battery readings.

I have tried juice defender before and it seems to me like I may not be getting messages and stuff in a timely manner with it. Can anyone recommend some good settings to use in Juice Defender? Sorry for the N00B question.

You can't wipe battery stats in cwm. It is not working. If you are running superclean 2.6 or higher it includes Adrynalyne's battery stat script. You have to download terminal emulator from the market, open it up, type su next to the $ sign, should say super user permission granted and you should see a # sign. Next to the # sign type bstats. After a few seconds you phone will reboot. Make sure to only do this when the battery is completely charged to 100%. Do that by charging to 100%, turn phone off with charger still attached, charge to 100% while off, turn on, let it charge to 100% again, then run terminal emulator. If you are not running sc 2.6 or higher you can download the bstat file from the first post of Adrynalyne's superclean thread here:

This worked for me. It does take a couple of days to notice results, but everyday, my battery life continues to increase.
One thing I noticed, is shutting off the wifi helps tremendously. Otherwise, it's constantly searching for connections. I have noticed no difference whether I leave the GPS on or not (so I leave it on).

Well every person has their own preferences when it comes to data and syncing but heres my setup:

controls: data
schedule: none
triggers: Batt 15%, screen (after unlock, ignore on low batt), traffic 50KB/15s
apps running: Visible Maps, Market, Pandora, Dolphin Browser

Profile is set at advanced
AutoSync: disabled
Screen: Enabled

Give these a try or choose a preset profile and see which one works for you the best. Hope this helps!

I have SC2.9.1 and am running juice defender on the default settings, I haven't noticed any lag in receiving text msgs, data is re enabled quickly when needed. I just checked my stats and JD says in the last 48hrs it has increased my battery x6.0+. I also followed gunners "how to" battery after flashing the 2.9.1 patch.

Thanks Mike, OP, I did exactly as you wrote and not I am back to 100% for a good amount of time! Had my phone since 11/2010 and this is the first time I have used the wipe battery stat option.

On a related topic is this fix battery or device specific? I am the one who warned you about the cheap i9000 batteries and not to charge them in your phone / car dock. Will I have to do the for each battery or is it device specific?

the clear battery stats isnt working like it should. i will update the op later today with adrys clear bat command. i should have done it a long time ago. lazy.

i dont know how non stock batteries will work. i havent gotten mine. eeerrr. they said shipping takes a while. they werent kidding. i will have to figure this part out when my batteries get here. i think you will have to clear bat stats for each battery. the phone doesnt read the battery, it reads the computer on the battery.

I've posted in this thread before I did not really see noticeable results from this method for a couple of days. Give it time and see if it gets better.

thanks landshark will keep an eye on it for the next couple of days also thanks for all you do on the froyo threads have read a lot and took the plunge on debloat and it rocks.

Updated to 2.9 a few days ago and everything is working pretty well except for the battery draining issue. Is there another way to fix the Bat Stat. issue? I was going to try the OP but I see in a few earlier posts that Gunnermike thinks that isn't working anymore. Any other ideas? thanks in advance.
