My daily ROM is vealpak but yesterday I was on cm7 final but I nanded back to vealpak and now I'm losing battery life fast I did the proper wipes even did vr format all zip any idea I use to get great battery life I use nat's 4.3.4 cfs havs more sbc kernel any ideas why this would be happening?

I know I post this a lot, but after anytime i flash a new ROM, or notice rapid battery loss, I have a battery routine I use, derived from the various conditioning methods on here, that works very VERY well.
1 - The "HTC Method w/10 Time Unplug"
Charge to full, unplug, turn off the phone, charge while off for another hour. Unplug, turn the phone on for 2 minutes, turn it off again, charge for another hour.
Unplug til the light goes off, plug back in til it turns green.
Do that 10 times.
Boot to Recovery, while plugged in. Clear battery stats, boot to system. And wait 2 mins, THEN unplug.
Also, I keep my GPS, mobile data and WiFi off unless I need it. You don't need either of those to make phone calls or texts
Yeah, you probably just need to wipe battery stats, but the method listed above is good for making sure the battery is actually at 100% when you wipe the stats.
Thanks for the help the wipe worked I think I'm going back to nat's 4.3.2 cfs havs more sbc I got better battery on that and for the charging method I would like to try that but I can't seem to put my phone down that long I think I would go crazy! lol

It probably doesn't have to be 8 hours, but I do it overnight, and on a weekend, when I can wake up and not need my phone for a few hours.

I flashed my phone to Caulkin Evio the latest version. and I really want to increase my battery life. I get decent battery life, but it trickles down to like 90% after using it for 5 min. What kernel should I download to keep everything running smooth. I appreciate links. Thank you.

You could try a netarchy 4.3.1 cfs sbc. The sbc will charge it, just read up on it first. I use it all the time for sense roms.
OK, here's what you do. Kernel selection IS important, but I do these 2 things that keep my battery fresh.
1) I do the battery conditioning techniques after any ROM I flash. The HTC method of an 8 hr charge, turn it off for an hour, unplug, turn it on for 2 minutes, power down, charge for another hour, followed by the 10 times unplugging, then plugging back in until the charge light turns green, unplug, plug back in, etc... 10 times.
2) I keep all my data turned off in case I need it. You can still text and make calls. When I need data or WiFi, I turn it on, do my thing, then off again, and use WiFi instead of Mobile Data when ever possible.
My phone has been off the charger for 4 hours now, made a few calls, and texts and I'm still at 100%.
all of the sudden every kernel I use drops from 100% to 94% within just a few minutes even after being charged extra. I was using net's 4.3.4 sbc no havs for awhile and sbc didn't seem to work. went back to sbc #15 and sbc worked for awhile then it just seemed to stop. then decided to use 4.3.4 no sbc no havs and less havs. Already setting at 89% since unpluged 30 mins ago. suggestions??
Probably damaged battery. Look on Amazon you can get a stock OEM Evo battery for under $10.

didn't damage your battery, you have to recalibrate it. there are a million ways, charge to full, go into recovery, wipe battery stats, then drain it so it won't even turn on and you will be fine.
FYI, my evo never charged to 100% from the day I got it. Non sbc kernels turn off the charger early because of the mV spike.
When you charge w/out an SBC kernel, the charger stops at 100% and doesn't start again until it reaches 90% but it still says 100%. If you're not using SBC, expect a drop of some sort when taking it off the charger until you get to 90%.

I will try this and see what happens. Thanks for the suggestion.
To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well.
this is a copy/paste from another post as well
I used to get all weird at the initial drop too, but the actual life of the battery isn't affected
all you're doing is describing the normal behavior that prompted the SBC kernels to be developed....lol

You have to give Kernels some time to adapt to your phone... you can't try it for a day and say OH THIS DOESN'T WORK IT SUCKS
Please, please, please. SBC kernel for Synergy?
I am tired of my 3500 battery running out after 18 hours, I was getting 60 hours from Warm 2.2 RLS5.
Sent from my PC36100 using XDA App
SBC wont give you better battery usage, just an extra 10% when you wake up. I highly doubt your 18 will turn into 60 just because of SBC alone.

Warm 2.2 was a great rom.that rom gave me the best battery life I have ever had except for my current setup...I am on wifi once I got home but 8 fairly rough hours on 3g. The wake time shows I used it.
I did get better life w froyo though. I could get 40+ hours pretty regularly and half would be 3g. If I stayed on wifi I am sure I could get 60+ currently.
Lithid, with all due respect, but I am on Synergy. When I charge my phone until the green light comes on, i unplug it and it drops from 100% to 80% in about an hour.
So I tested some things out. I ran battery clear dead and recharged, phone on, and then when the light turned green, I rebooted it and when it booted back up, battery monitor widget said I was at 79%.
Ran dead again about 12 hours. Recharged, phone off, until light turned green and turned on phone. BMW said 78%.
I am not very smart, but both times it took 2 hours exactly to recharge until light turned green. That is telling me that the phone has a timer, or shuts down charge at a certain voltage. It also tells me that it takes the same amount of time to charge my 3500 battery as my old stock 1500???. I call BS!
With SBC, it took 3 hours to fully charge my 1500, and almost 6 to charge my 3500. So what you stated above, makes no freaking sense to my stupid arse. Please re explain to me again how I was not getting 3 days of use before and only about 17 hours today with screen on time of 3 hours today....

I don't know what you guys are doing to get such terrible battery life. I get 19-20 hours with moderate use out of the stock 1500 battery.

So this morning, I unplugged at 9am from charger. I turned off everything that makes an EVO an EVO, like Background data, and sync so that it does not update any fb or email or anything without me doing it. I have had WiFi on since then and I have it set in Spare Parts to never while plugged so it will shut down when the screen is off. I also turned off Mobile network always on. so I now have a NON EVO, EVO. And at 5 hours, I have 71% battery left. That will get me to to about 17 hours of drain time. so far today I have 2 hours online with it. The 17 hours is purely estimate as I may go 5 hours later without picking it up. so I may be more like 24 hours on this charge cycle.
That is no where near what I was getting with SBC and RLS5 of 2.2. With Synergy, I am not expecting the same run time as before, but with SBC, I would definately be getting WAY MORE life out of battery. 2 days at least.
All I am saying is the the EVO without SBC, DOES NOT fully charge my 3500mA battery. PERIOD!

I agree 100%. I wont use any sense 3.0. Gb rom until an SBC kernal is available. I myself wouldn't use it but my gf would. I'm a cm7 person and only use SBC cause I need every drop of battery life possible. Without SBC I get that initial drain and I wont sacrifice that. For me its safe and a must have and people can disagree with me all they want on the validity of SBC but I believe in it and won't change my mind. If I ever get time I might throw my hand in to creating a kernal but right now I'm working on my apps new release

Nothing wrong with SBC and s reputable replacement battery. Mine is a Seidio and I used SBC for 4 months on 2.2. No problems! Well except only charging every 3 days unlike everyday now.

update from Today on battery life. I am not at 13h 48min since unplug and BMW says I have 12% remaining and estimates that dead time is 1h05min.
Display time on is 78% and in time that is 5h 48 min.
Wifi on 9h, 8min. I had to make a trip to the grocery store and pharmacy. Dont know where the other 2 hours of time went that it should have been on, cause I did not turn it off.
Phone idle, 7h 55min
I would consider this a normal day. Only about 10 min of talk time. I got similar to this with Stock ROM and a 2600mA battery from Sprint.
If your battery is registering fully charged at 78%, then you must've wiped battery stats without a full charge or something. Charge it fully & then wipe battery stats. Let it drain completely, then charge it fully again. You should get better battery life after doing so.
I've seen in some people's wiping/flashing directions to wipe battery stats (or everything except the SD card), and that's incorrect. Don't wipe battery stats unless your battery is fully charged. Wiping at less than a full charge, or not following through with the conditioning directions, can mess with your battery life.

No, I did not wipe battery stats. How would I get fully charged if the phone will not let it fully charge??? That is my complaibt in the first place. It is NOT charging my 3500 battery anywhere near full charge.
Sent from my PC36100 using XDA App
I was not talking about when your phone is fully charged. I'm saying your battery will still drop the same at 100% or 90% you said at 100% you can get 60 hours. But at 90% your only getting 18 hours or whatever... I was saying, doing that math it doesn't make sense. I also use the 3500 battery. No sbc and I charge to 100% not 78%

Gotta disagree with lithid here as well. If you watch the amps separate from the charging indicator, they keep going at max after the charge hits 100% and don't stop until it gets fully charged. For me the full charge without SBC is about 70% of the actual battery capacity
Lithid, I just ask that if you were to unplug your phone when your led turns green. Then do a full restart, BATTERY MONITOR WIDGET will show you your exact capacity charge and it will not be 100%.

I also want to add....
Lithid, I totally appreciate your interest and I hope I have not offended you or my posts read like I dont care what you say. I try to be respectful, but sonetimes typing out things come across wrong to the reader. You have done some fantastic work for the EVO and I think you are first class for doing it.
You have also caused me to research things so I can learn what you are talking about so I dont come off as an idiot.
The only thing that is troubling me is that I freakin love Synergy. It drains my battery very quickly compared to 2.2. My hunch was that the stock kernel was the culprit. I tried golden monkey and freedom, same problem. I tried chop suey today. I am at 10%, so it is about the same as others. CSuey is a bunch quicker than the others for performance.
So I guess what it comes down to is this; I would just like to try an SBC kernel for Synergy just a. Couple of charge cycles to see if i still get the same endgame. If I still only get 18 to 24 hours of battery charge, I will be a non SBC guy forever. But no one is doing one, so I can not test it. Solution???
And again, Lithid, thanks for your time on this and keep up the good work! I appreciate it!

Stock 1500 running synergy godmode. Moderate use checking email placed about 15 calls. Checked xda on the hour. Downloaded apps. Browsed the web and listened to music for a few hours. I think your battery might be going bad. Also if you have a taskkiller you need to get rid of it. I let Android do its thing and have had zero battery problems. I easily get a full day and then some out of my EVO.

Small update. All these nay sayers about SBC got me thinking, and the one above that said my battery may be going bad, so I am now back in Myns 2.2 RLS5 and SBC#15 kernel. My old setup. I am going to charge my battery FULLY tonight, and in the morning, I am going to see how long my battery lasts on that setup. I was getting 2.5 to 3 days with moderate use.
Then, when it gets dead, I am going to Recharge it fully and then immediately flash Synergy and then see how long of life I get with a SBC charged kernel and the reflash and see if I get more than 18 hours.
If nothing changes, then I will forever shut up about SBC. If I get significantly longer life, then I will pay someone to do an SBC kernel. Fair enough??
Plugged the phone in to charge at 1:05am today. Light turned green after 3 hrs 15 min. It is still not fully charged and that is at 9 hours 15 minutes. It is almost there. Right now it is showing 22mA charging and dropping. Goal is 0, which means full charge using SBC. I do realize that SBC also charges the battery at a slower rate, but that in itself cannot explain how the phone said the battery was FULLY charged after 3 hours.
So as soon as it gets to 0, I will reboot into recovery, wipe batt stats, then reboot into 2.2 RLS5 and unplug. Then I will run completely down until phone ****s off, then recharge once again using the SBC kernel, once fully charged, I will reboot into recovery, restore my Nandroid of Synergy RLS1 and see how long batt lasts on SBC charge. Then when I run that completely dead, recharge using Stock kernel from synergy and see what happens.
Screw SBC, I'd be happy with HDMw1n, 2-way call recording, and standard speed enhancements ALL in one, stable kernel. We don't have that yet.

Ok so what ive read and heard is that calibrating your battery after a new rom will give you quite alot more battery power (Which im like obsessed with), but anyway ive read that
1: Charge your battery to 100%
2: Boot into recovery and wipe battery stats or use a battery calibration app to do so
3: Now let the battery die completely so you cant turn it back on
and 4 is what im wondering about.
4: Charge your phone to 100% while its OFF.
Im a very busy person and have important things to be doing and i dont have 3 or 4 hours to have my phone off charging up.. sure having it on and charging is one thing but off while charging is another.
First: Can i calibrate it by charging it while its on after dieing? Second: Is there a work around to finish the calibration if i HAVE to have it charge up off?
Any help would be appreciated.
Also. YOUL GET A COOKIE!
Try this,
Plug in charge till green
Unplug power down
Plug in (while off) charge till green
Unplug power up
Let it completely settle
Plug in charge till green
Power down
Boot into Recovery
Wipe Battery Stats
Click the link in my sig, scroll to battery life. the part where you have to turn your phone off can be overnight on a weekend, maybe.
It's not advisable to run the battery down to zero, btw

I've heard it both ways. If you charge to 100% without unplugging, you should be fine with keeping your phone on.
Also realize that if you're using an SBC kernel then you don't really need to calibrate your battery. You can, but I don't know if it'll help much.

You either need to calibrate your battery (app off the market). Or try using a SBC kernel, which properly charges your battery to its full capacity. Make sure its an aosp kernel like mason, or taimat.
Lol sane experience on morning
wanam v10.6 siyah v3.0.1
Definitely needs calibration.Just search for how to properly do it on the forums.I personally use battery calibration from the app store.Charge the battery to 100%,then use the app.Unplug through phone and use the phone all the way until it dies on its on.Then plug it in without turning it on and wait until its fully charged.Turn on and use it once more until it dies.Charge again to 100% then after that you should be good to go.Hope this helps ya.

A non-sbc kernel will charge to 100%, then begin to discharge to about 90%, then cycle back up... Depending when you pull the plug, in reality it could be anywhere inbetween that range, so 100 is not a true 100... Calibrating the battery by deleting the bin file doesn't produce any long term results..
A manual way to mimic a full charge would be to charge to 100 percent, unplug, plug back in for a bit and repeat about 10 times, and it should give you a decent charge.
That's a manual way of doing what a SBC kernel does automatically for you
Hey,
Like they said get the SBC, and calibrate your battery, and that should fix it.
I assume at night you are plugging it in till the morning, and this is your issue because in the middle of your sleep it is reaching full and stopping its charge. so by the time you unplug it drops down to how much it discharged.
Charging with your phone off solves this to
Let your phone completely drain till it turns off. Charge the phone while its off till you see the green "charged" light. Unplug usb, wait for green light to disappear and plug usb back in, phone will still charge. Repeat process about ten times. On the tenth time boot into recovery and wipe batt stats, then reboot phone.

Good to see that worked for ya. I'd +1 the SBC kernel if you hadn't found that it has been working for you. I've been using Mason's 14 with ICS for a few weeks now and i've found that with the screen off, the battery sits at 100% for quite a while. I haven't used the battery calibrator and maybe i should see how that helps. Does it show significant results or is it mostly a gimmick?

Im not sure what everyone on here thinks it does, but calibrating the battery is strictly for stats. It will not lengthen the battery life or keep it from draining down from 100% faster. All it will do is assure that your battery stats, aka estimated time you have left on your battery, are more accurate.

good luck. I tried sbc and it was working well for about two weeks, then my battery suddenly started draining super fast. Rumor has it that SBC will in time ruin your battery, which it seemed to possibly be doing to mine. Got rid of SBC, flashed back to build28, ran vipermod script and undervolted -75mV and im magically back to normal.
My findings are that if I just run the stock kernel with build 28, I get the best battery life. As soon as I started trying mason kernel, tiamat kernel, or even faux kernel on build 31, my battery drained too fast for my liking. Thus far I have reached 40 hours on my battery on build 28, with vipermod, stock kernel!
I just got brand new batteries, i have not calibrated nor wiped battery stats after flashing. I do have Mason's kernel and am under-volted by -50. I also have an app called battery xl it helps control what is running when you may not be aware or forget. My battery stays at 100% for over 2hours with minimal use. The only thing i heard is that you have to use the battery down to 10% and then charge while phone is off.Do this about 4 to 5 times and that conditions it(when it's brand new) and it will help your battery last longer before needing a replacement.
Just my .02
Several people have reported bad experiences with the SBC kernels, but there are many more (myself included) that have had absolutely no issues with them and I have used several iterations of the SBC since it was first released for the Evo.
At this point, for me, the benefits more than outweigh the risks. If you do have a problem, buy a new battery. They are pretty darn cheap these days.
