I can tell you i've done this and havn't noticed any difference in battery change. I use skyraider 2.5.2 and KK #3 kernel. Bump Charge and work gets me well through the day with moderate use.
I've done this a few times too and haven't it do anything.
ive noticed a change when i charged fully while the phone was on and the light turned green then just rebooted in recovery and wiping battery stats i do it every time i flash a new kernel i mean my opinion i have noticed better battery life doing this process

Is it necessary to wipe battery stats every time I put in a fresh battery? If so, why? Thanks in advance.

Well it helps, because it'll help it charge more accurately.

Ok! That makes sense. Thank you.
I wont forget to hit the thanks button once I get to my PC. We need the "Thanks" button within the XDA app.

Wiping battery stats will do more harm than good if you don't properly calibrate the battery. Let it charge fully, wipe stats, let it drain completely and then do a full charge again. Otherwise, your battery might die super quickly.
Although I'm honestly not too sure on how different batteries are effected, which is something I should probably look into before I get mine in the mail.

Same here... and to OP I just got new 1800mAh batteries and im going through the charge cycles... no real issue with battery life... its lasting approximately good 20+ hours [with HEAVY use]
You really only want to wipe stats if/when flashing new ROMs

no wipe necessary if using sbc kernels, apparently its placebo anyways but to each their own

So is it safe to say only wipe stats when putting a fully charged battery?
Thanks.
I've noticed since rooting I have worse battery life...also reception is not as good

Granting applications Root access does absolutely nothing to effect your reception or your battery. Notice the Big period
Installing apps that constantly run in the background, will kill your battery.

You gotta get a ROM. You will find that they are improved with more battery life than stock. And Jangst is absolutely right. Rooting.will have no affect on your battery life other than your display being up so bright.or running applications in background.

I feel ya there. I'm the same way. I am using the deodex stock rom from Bubby though. Just in case I want to do stuff later on.
I also tried different kernels and am now back with the stock one. I got worse battery with non stock kernels. People will say otherwise, but I use my phone the same daily, and I can easily tell.
"Omg 28 hours battery on one charge" <- Nope, ain't happening if you actually use your phone like I do....

Which root method did you use?
You may have inadvertently screwed up the battery stats while rooting!
So you may need to recalibrate the battery.
I resisted rooting for the 1st two weeks and I can say I definitely get better battery like with Juggernaut and Bullet.
So give this a try.
Here ya go
Try charging to 100% then
Shut off, Pull battery for about 1 minute, replace, and charge to 100% and with the charger still plugged in
Boot to recovery
Wipe cache partition, then in advance wipe Dalvik and wipe Battery Status
Reboot after 5 to 10 min, unplug the charger and reboot
Or before Flashing a ROM or Kernel
My personal theory is that flashing on something other than 100% full battery screws up the calibration! So,,
Charge to 100% before Flashing
Then only wipe Wipe cache partition, then in advance wipe Dalvik and DO NOT wipe Battery Status
Works for me
If you don't have recovery!
Try charging to 100% then
Shut off, Pull battery for about 1 minute, replace, and charge to 100% and with the charger still plugged in
Reboot and try the following posted by explodingboy70
Calibrate your battery!
- There seems to be a safety feature in Gingerbread or Samsung's version of Gingerbread that causes the battery to start draining when it reaches 100%. That said to calibrate your battery properly you must do it as soon as the battery full pop up appears.
- Download the app found here http://forum.xda-developers.com/show....php?t=1024867 and follow the on screen instructions.

You should give the custom kernels at least a week to set in. I didn't get amazing battery until like 5-6 days after I flashed bullet kernel. I'm on stock rom as well....

Might be a coincidence but tmpbile might be messing with the towers in your area which gives u bad low reception. Low reception = fastest way to kill battery

Hi guys, I tried searching through the forums to find the answer and didn't get far... I am currently running Calk's ROM v 2.6 with Rogue recovery and EL13 modem and I feel like my battery dies way faster than most other ROMS. I noticed that Rogue recovery will let you wipe battery stats, and was wondering if I can some how try to re-calibrate my battery or if there is anything that I can do to improve the battery life on this ROM. I noticed that there are some zips that I can flash on the same thread of where I got the ROM, will that work with v 2.6? Sorry I'm some what of a noob, all I know is how to flash ROMS and bring my phone back to stock. Thank you guys in advanced!

I'm using the full version of the ROM btw. I believe I'm on EL13 kernel as well...

Hello, ive asked the same question lol so Ill pass my knowlege along. From what ive learned, if youre using rouge recovery there should be an option that says wipe battery stats under wipe, but you shouldnt do that first. In order to do a full battery callibration, you need first charge your phone to as close to 100% as possible, which means you need to charge it fully while its on, turn it off and charge until it says fully charged then turn it on and charge it again.. This process shouldnt take over ten minutes after it charges the first time. im not sure why you do this but I think its too ensure it fully charges. Once you do that.. Go into recovery mode and go to wipe/wipe battery stats, reboot and make sure to leave it off the charger until it dies completely, use as normal, then charge fully without interruption. Then youre done.. Hope this helped brah

There is a battery calibration app in the market as well. Plus you need at least two full discharge cycles with a new rom/kernel to really start gauging anything...
Thank you, thank you! I'm going to give it a try... I will post again with my findings.... Oh, btw I flashed the 100mv undervolt zip that Calk posted as well and it seems to drain a little slower...

at this point we don't know what ROM/kernel zakkkkk is using, so droidzone's may not even be compatible.
calibrating does not increase battery life, just might stop if from shutting down suddenly at a higher than normal percentage.

so what rom/kernel combination are you running at the moment, did this occur after flashing something/installing an app?
in the battery usage, is it shown as awake during this time? i would check using something like betterbatterystats to see if anything is accidentally keeping it awake.
if there is still a problem, make a nandroid and do clean install of your ROM or 2.3.3 RUU without installing anything else, see if the problem still persists. may then be hardware.
(can't remember exactly, but i think the dialer issue could have been a gb sense error, which reported it much higher than it actually was actually using. i remember clicking the dialer battery use and seeing the actual cpu usage and runtime was minimal)
im using droidzones supernova rom and have been using it for about 6 months now. my battery life has been excellent. this problem only occurred today. i installed a few apps/games over the weekend but i dont know which one is causing this. i have also tried uninstalling a few but with no affect. are the any apps in the market that show which apps are draining battery?

sounds like you've partially answered your own question...
if you were having excellent battery life, then suddenly went bad after installing something, then this is the likely cause...

I flashed calks 1.6 the other day and noticed big battery drain. I reflashed today just to make sure. Drains about 20% an hour in my pocket. As soon as I start using it, it drains so fast i can watch the percent countdown lol. It dropped 20% posting this. Its also charging weird. When I plugged it in it was at 65% and in 20 min it was full. This is very odd because I used this rom many times and it had great battery life. Anyone else experience anything like this on their E4GT ?

Must be a bad battery, how long have you have your battery? also have you removed battery stats?
Try using phone at maxxed out power until it drops to 0% then recharge battery until full, I recommend overnight.
And get back to me...
I don't think its the battery unless it went bad overnight lol. It was fine the other day. Something weird happened a few weeks ago i dont know if it has anything to do with this but I flashed a rom that I had flashed before many times (phantoms blazer ics) and it aborted the install. I reset my phone with sfhubs one-click , formatted it,
And tried flashing a new rom and same thing. I posted about it in Q&A and no one really helped out too much. I tried everything new downloads, new kernels you name it I tried it. And it still happened, everything I tried, to flash got aborted on el26. It was so odd cause it was doing it to old downloaded roms and the el26 I've been using since ics . I could flash a gb rom in el29 but as soon as a flashed el26 and tried flashing something it would happen again. The only thing that would flash successfully is calks format all (every time)So I got frustrated, and i stayed on stock rooted el29 for a week or 2 since no one would help. The other day I figured id try again off a fresh reset and new downloads, and it went fine, I flashed a few roms but decided to go back to calks 1.6 . And now the battery issue ? Should I wipe battery stats? I don't really know what that does. Btw I reflashed and it didn't solve anything, still draining. I will try running it down and charging overnight. Any other suggestions?

Did you flash back to gb ?
Or flash another Rom but imo its probably due to an app installed that's not ready for ics
only thing I can think of is I downloaded the T.5.3.0.32 VVM for ICS. The one I downloaded is supposed to safe for ICS. You think that could be draining my battery?

Time to upgrade to a released rom....
Calk's 1.6 is based on old, unreleased code and isn't supported. Calkulin has moved on and no longer dev'ing for this phone.
I would like to but I liked that rom for its stability and battery life, but my question is why is my battery life bad now. Ive ran this same rom (same download) before and it was great. Why the bad battery life all of a sudden?
