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

Helpp! Terrible battery life...

So I've had my evo a couple months and just realized how bad my battery is compared to people on here. Some people I've seen can go more then 24hrs without charging, id like to know how?
Basically I charge my phone all night wake up at 7 go to school (don't get great service if that matters) I might have the screen on and texting/internet about only 25% of the day. Then by the time I get home at 3 im around 20-30 percent? I'm running miui rom i also have my email refresh to never, have setcpu to the lowest when screen off and screen brightness usually 50%. Also I'm using the stock battery but going to buy the gallios 2000mah or whatever from ebay.
Sorry for writing a book i just need better battery. I've seen threads everywhere about this but I just want to hear everyone's tips. Thanks

yours just like me, my phone is on 8 hours (while inm at school duh ) and i say i use it for about 2 hours while im at school. i use a sense rom (AOSP roms give me horrible signal) and when i leave school im about 90%-96% . i use SBC kernel and give it 3 days to settle in you wont see the battery life instantly. try it out

Thanks. Will an sbc kernal work on miui? I've never used a kernal...do u just installed them like roms? If so what data do I wiped? Sorry for all thames questions.

I reccomend the savaged zen HAVS CFS kernel...I'm on stock battery on CM7 nightlies / with WiMax, and I have had my phone unplugged since 8am, and still have 48% left...I'm able to go about a whole day.

I also have a question on kernels while we are talking about them. Is there a certain way to install them or do i just install the zip through the boot screen? I installed the newest ziggy kernal, dated nov 24th but didnt notice a change in battery life. Any help?

Download the 8th one from the bottom
its named :
Savaged-Zen-V0.0.5-CFS-HAVS-SBC-WiMAX-Froyo-Signed.zip
and yes it works on miui clear cache and dalvik cache and flash the bad boy. you might see bad battery life for hours or day but kernel has to get use to the ROM it will start to work out. and once your phone gets to 100% on battery it is still charging

Is that the same for all kernels? They take time to adjust to the rom? Or just the kernel you are recommending right now?

All kernels take a couple days for the to "set in."

Ya that's the reason I want it I let my phone charge overnight to 100. So with this rom it will keep charging all night? If so ur saying it won't work in the morning if i install it tonight?

You can use SBC on MIUI, I'm using the one posted in this thread already, works great.

Can someone link me to the sbc kernal I would use on miui? I'm new and don't really understand which one to choose

1. Boot into recovery
2. Wipe cache and dalvik cache
3. Flash your current MIUI rom (I've had the best results flashing kernels this way)
4. Flash the kernel.
5. Boot
6. Drain your battery low and boot into recovery and wipe batt stats.
7. Boot back up and let it die.
8. Charge to full.

What hardware do you have? If you have an 003 or 004 you may have issues with the screen waking up with this kernel. If so, flash the Savage 1.6 CFS SBC http://dl.dropbox.com/u/18860340/Savage-Kernel-v1.6-CFS-HAVS-WiMAX_SBC.zip.
Set your setcpu profile to conservative. You'll get the best battery life that way.
I'd recommend downloading Battery Monitor from the Market and putting the widget on your homescreen. When the mAh drops into the teens, your battery is full.

It's under hardware info of about phone. You can only see it on a sense rom.

Im planning to go back to http://forum.xda-developers.com/showthread.php?t=935275 CM7-GX4(EX+4G), is that the same one you are using, if so, are you using another kernel then the one suggested? If so which, because I also only get about 10 hours on cm7, I want to use this on my main evo. Miui 1-14 is the one i use for my ipod evo it last 45-50 hours on avg.

Just to jump in real quick, I am using Myn warm 2.2 and the battery life is amazing and I don't even use a different kernel than stock. I'm talking twelve hours easily with heavy use

[Q] Wiping battery stats

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.

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.

How do I wipe battery stats through Rogue Recovery running Calk's ROM v 2.6?

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...

Should I Wipe battery Stats?

I notice in the CWM recovery menu under advanced there is an option wipe battery stats. Is it recommended to wipe battery stats upon new rom/kernel flash?
I never done it before, but last night i was on the play store looking at battery calibration apps, reading the description, and basically what they do is wipe battery stats so the old stats from the old rom/kernel don't stay.
Do you guys do it? Thanks!

I don't wipe stats because is an extra step and don't find it useful at all

yes i know it does not improve battery life... but what is the point of battery calibration then? because that's all it does, is delete the old battery stats the older rom/kernel had...
true on the extra step part, but it takes no 20 seconds at most.

your phone automatically wipes batterystats.bin every time you unplug the phone from the charger. "battery calibration" is not only a myth, its a waste of time and does absolutely nothing beneficial for battery life

Yes it does... it makes them bad, that they've been before!
