Sbc kernel on miui - EVO 4G Q&A, Help & Troubleshooting

I've tried sz's and tiamats sbc kernel on miui and neither one seems like its working, I still drop 10% in 30 minutes. what am I doing wrong. I'm charging all night long.

A good battery calibration is a good way to start.
Here's my method:
Plug and charge til full, with phone off.
Unplug, turn it on for about 5 minutes.
Turn it off, plug it in and charge for one hour.
Unplug it til the light goes off, then plug it back in.
Once the light turns green, repeat this step, unplug, then replug til green, about 10 times.
Boot to recovery, wipe battery stats, boot to system.
Also, I've been running Tiamat 4.0.7 all week, and it's better than 4.0.6, but not quite as good as 3.3.7 was.

I asked about this on the MIUI forums the other day and someone told me about a battery calibration tool and the market. I guess it deletes the .bin file... It worked fine for me. On light use i'm on 15 hours at 80%

I used that battery calibration app as well, and my 3.3.7 SBC works just fine on MIUI. That being said, I got miserable results from 4.0.7 SBC. It gave me wakelock issues which were resolved by going back to 3.3.7. It's all about finding what works best on your phone.

[Q] Confused on battery life... please help

Hey everyone, I am having some trouble with my rooted phone. Prior to rooting the phone, I had no battery life issues. Right after Christmas, I had a little bit of time and I rooted my phone for tethering, mostly. I used the root listed on this website at the time (I couldn't use unrevoked because I had just done the OTA update to the software) and installed no further changes. Since then, I can get about 8 hours before the battery is well below 50%. This is without making any phone calls or using the internet, and maybe a few texts. I have resorted to turning off the connection to the internet, and this preserves my battery and allows me to make some calls without absolutely killing my battery. When I unplug, I can almost watch the battery life drain. I will be at 90% by the time my 15 minute drive to work is done. I have tried changing chargers, buying a new battery, and nothing works other than shutting off the connection to the internet. When I look at what has been using the battery, I not no time where I did not have a cell connection, and all the battery usage is idle and connection to network time. Any and all help is appreciated. Thanks!
Wow, your situation seems very strange. Are you running a custom ROM or kernel? Have you tried using spare parts to see what is actually consuming your battery? Perhaps, you can try wiping everything from the phone and installing the stock ROM or other custom ROM of your choice. Please keep us posted, good luck
Recalibrate the battery. I would link you but kinda hard to do so. Just search the forums for it.

What Rom are u using?
That is happening to me too. After I first rooted the battery life was good better than before. I had been using vaelpak, then a about last week my battery started to drain so fast. I would take it off the charger and do a little texting or check my emails. Shower or what not than I pick up my phone and its like 92% already. Thinking maybe I have too many apps so I deleted some and then forced stopped a few and I forgot what else and that day my battery stayed on 60%(thats what it was on when I took it off the charger before I left) for about a good two hours and i was listening to music and the internet and text and all that. Kinda scared me because I thought I messed something up, but the battery lasted longer that day. Then the next day back to the same old same old. Last night I flashed warm twopointtwo and was charging my evo last night but I put it under the pillows by accident and woke up this morning the phone was burning up and flashing red and green at the same time and it had stopped charging. I took the battery out and let it cool for a few hours. now its charged back up. I wanna see if the battery improves with warm but I think I'm going to flash another ROM but this one is too pixeled and its killing my eyes So upset. but let me know if you fix your battery problem
hmmmm....maybe....

I'm having similar problems, though not as dramatic - mybattery life only lasts about a third of what it used to. I am running 2.2 RLS 5 witht the htc stock #15 kernel. What I am trying to do is hunt down a decent kernel that is compatable with RLS 5. I have found a few - but I am still in the process of researching information about the issue.
I have found 3 differant ways to reset your battery... I'm going with the last one (blue) for now and am currently in the process of executing it right now, but here are the three steps I have found while reading:
Charge the phone fully with it powered on
When fully charged, disconnect cable
After green LED goes off, power the phone off
When phone is fully powered off, reconnect cable, amber charging light should be on
When LED goes green, disconnect cable
Repeat previous two steps 10 times
After 10th cycle, boot into recovery and wipe battery stats.
-----------------------------------------------------------------------------------
this is one from HTC
Charge the phone for 8 hours uninterupted with power on
turn off the phone and charge for an additional hour
turn ont he phone unplug it and let it sit for 2 minutes then plug it in for an additional hour.
-----------------------------------------------------------------------------------
charge the phone to full
unplug and use phone till it shuts off from no battery (do not plug in until it shuts off)
charge phone to full again with out unplugging till 100% (check under about phone > battery it shoudl say full charge there)
then boot into recovery and wipe battery stats
reboot back into phone and charge too 100% with a wall charger( don not unplug until at 100%)
-----------------------------------------------------------------------------------
After I try this out - I might or might not switch my kernel - But I wll say this - I had absolutly awesome battery life when I was running HTC stock #17 - you might could look into flashing that instead of what you are running now (flash it just like you would a ROM) - you can find it here
hope this helps out a little bit - but in reality - getting your battery the way you like it is really more of a trial and error type procedure...good luck
Ah, welcome to an elite club...right. I rooted my 003 Evo last summer after getting it shipped to me. From then until mid-november of last year, I got great battery life. Before the switch flipped in November, I could leave it sit overnight and i'd use 1-1.5% charge per hour, so worst case after 8-hours sleeping with no use I'd be at 86-88% charge.
Then suddenly as it a switch had been flipped, I started getting horrible battery life. The ROM didn't matter, settings mattered little, it just sucks no matter what I do. If I unplug it at 6:00 AM and leave it completely unused until 2:00-3:00PM that afternoon, the stock battery is at 31-35%. The awake time will be under an hour, and every utility that I use reports nothing out of the ordinary.
I bought a 3500 mAh battery and its better of course, but gets me nowhere near the use what the stock battery used to provide. I unrooted back to stock with the same results so I rooted again of course. Might try flashing back to the 1.77 PRI and NV. Some folks are getting better battery life with those, but that may only be related to sleep issues which my phone doesn't appear to have. It may prove to be a waste of time, but I have to keep trying.
Good luck all of the club members! Thank you for your time.

Tried the middle one from HTC as well... we will see how it goes. Just in the time I have been typing this message (about 2 minutes), my battery has gone from 91 to 88%.
Also forgot to add that I have been out of town every week for the last two months and noticed that the HTC weather thing on the startup screen hasn't been switching to my current location. Always shows my hometown, even if I force an update.
I think I figured out the problem... ran into several threads discussing PRI incompatibility with HTC kernel #15. Flashed back to 1.77 and doing much better. Didn't mess with the NV. We will see how it does for the rest of the day.

Battery Life

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%.

Used sbc kernel and now..

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

yeah but it wasn't this bad for me before sbc 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

Losing battery life....

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.

Battery won't completely charge, says done at ~65%

So I've had my phone for about 2 weeks and rooted it on day1 with Calkulin's rom.
I charge overnight and when I wake up after it being plugged infor 6-8hrs or longer, I'm seeing a blue light but the battery is only at about 65% (this happens every night).
If I unplug/plug back into the charger it goes orange again and continues to charge. Then it stops again at 75-80% and I have to do the same thing.
I did try a battery calebration with clockwork recovery when I first flashed the phone. Other than that, I don't know what else to try.

It seems like you need to wipe the battery data from recovery mode.
Here are some related threads -
http://forum.xda-developers.com/showthread.php?t=1517044
Or you can just search with 'xda wipe battery stat'. I will show you thousands of returns.
Try going in to the CWM recovery and go to "wipe>battery stat, than reboot you. That should put you at the true % value.
