Battery life issues! Possible kernel and wake lock? - Epic 4G Q&A, Help & Troubleshooting

Ok so im not new to rooting as I have owned a Hero and an Evo 4g for some time. But now I am running an epic 4g and I am having terrible battery life throughout daily use.
I am running the leak of the stock build EF02 and the light tweaks that were in the forums such as ram booster. After checking my phones up time it says it is 14 hours. Which means that it has not slept and clocked down sine last night when I put it on a charger. This is obviously a kernel and/or radio issue. But the problems is I need to know what radio to flash to fix this. There was a very similar issue with the Evo when it ran an incomplete gingerbread kernel: Flashing a new radio fixed it.
Can anyone give me some info and input on this subject because I think if Im getting this problem then there are a lot of others who have it as well.
Thanks

new sprint kernal vs cm6 on batt life

i have been running flipz newer rom with the new unreleased kernal and my battery life is AMAZING, I mean very very good. I was thinking about giving CM6 a try again with flashing the new v7.6 kernal thats supposed to be really good.
But I was wondering what people are getting with cm6 and the kernals as far as batt life.
Ive never personally flashed a kernal before so not sure on how well or how much they affect the phone or if its worth it.
any help? like as far as the best kernal for a CM6 rom and and reports on batt life comapred to the new leaked kernal
I'm getting better battery life on stock now, then I was on any other modded kernel (kings, cm6, and some others.)
Nand backup and give it a shot. It seems way to better to me than stock or even cm6 nightly with newest kernel.
also whats the difference between bfs and cfs roms?
i feel batt life with CM6nightly + snap7.6 in turbo mode is about how the phone was when it was first released...you can make it a day with light use, but using it a ton, i seem to get around 8-10 hours.
However...getting 2600+ in Quadrant and no lag, anywhere, ever...makes up for it. I'm always within reach of a USB port or wall outlet so i just carry the charger/cord around with me.
I haven't actually ran it from full to dead outside of work. However at work i constantly drop signal and regain it repeatedly for the 8~ hours i'm here.

[Q] Latest, safest radio for Telus DHD?

What is the best radio for the Telus DHD? Im having battery drainage issues
bump.
would like better battery life
I would also like to know the Safe radio options for Telus DHD
I have seen a few dotted around and some that are reccommended to gain the best peformance with specific roms (revolution for example) But i know changing the radio can sometimes be risky.
Thanks in advance.
oh and equlizer have you tried wiping battery memory, that worked a charm for me...
yep, battery issues fixed

Glad to hear it!
Ive been trying to find posts with people advising against radio, or recommending the best fit (or general) radio compatibility with the Canadian Version of the Phone but i'm having no luck,,,
So far are the DHD radio's have the ability to be rolled back without issue?
Are there any specific radios that seem to brick the canadian version of the DHD?
does anyone have a definate answer?!
I think it depends on which rom you are using

Hi,
My radio is 12.28b.60.140eU_26.03.02.26_M and I installed a Stock-rooted Gingerbread ROM.
It came with a radio but I didn't flash it (Mabe I was scared or just wanted to test the ROM first who know...) the fact is since then, my battery life as improved and the radio signal is good enough that I didn't flash it.
(24-32 hours of autonomy with a good use of my device)
Should I think again and flash the new radio anyway ?

Radio (12.28b.60.140eU_26.03.02.26_M)
I live near Ottawa, but in a lower reception area, and I have been trying radios trying to get a good mix of reception and battery life.
Currently I'm using "Radio_12.35d.60.140f_26.06.03.24_M2 - TELUS WWE 1.84.661.1" and the corresponding RIL on Leedroid GB rom. It seems ok for now, but if anyone has tried a bunch of radios and can suggest their own best results for us Canadian desire owners, I would be much appreciated!
a fellow telus dhd owner here in edmonton. i'm using the latest radio (check sig) with g ril on cm7 with great results. i was using hm ril's for a bit and the device had very poor performance (calls cutting in and out, slow gps sat lock, wifi/3g sporadic disconnect/reconnect, etc). all that has been remedied by just flashing a g ril instead of a hm ril.
i think it'd be good to remind everyone that matching your radio and ril to your rom type (i.e. sense vs asop) is also important. from what i've read, use g for asop and hm for sense roms. it sure made a difference for me.
Thank you for the good advice. I switched up to the newest radio and ril and they seem the best for me I am still interested to know what others agree having success with here in Canada

I'm a fairly new user, got my Telus DHD (first Android) in the beginning of april, I live in Montreal, and took the entire phone apart within the first week. Tried a whole bunch of roms, then learned the hard way that Sense roms are like beautiful girls in bars at 2 am, they get you excited at first but then it's all disappointment... Lately I've been playing a lot with cyanogen nightlies, and I've been trying to find the best battery life possible.
So far the best I got was CM7.1 RC1 with Radio_12.35d.60.140f_26.06.03.24_M2 - TELUS WWE 1.84.661.1
That would last me over 35 hours very consistently with heavy use, screen on and lots of data (3G)
I tried pretty much all other radios on the latest nightlies (right now #170) and haven't found anything as good as 26.06.03.24_M2. I am in the process of reflashing that one while on this nightly to see if things will go back to what I had.
When you know your rom (and apps running) are not draining the battery, is the radio/ril the only other variables that affect battery life ? In other words, would the same radio/RIl drain the same regardless of the rom you're using ?
(forgot to mention I flash Alienmind's stuff over that, so I also use LordModUE v6.9.2 kernel and I change the OC to 122min/1.3max and use Brazilianwax (that governor seems so far seems to be the best)

[Q] New to the Dinc. Need Advice?

I'm an og droid user but just picked up a Dinc for my fiance. She loves the thing but hates the 10 hour (9 hours of that is idle?) battery life.
Last night, I went ahead and rooted it and removed most of the verizon crap-ware and then adjusted her sync settings to hopefully improve her battery life. I also did a battery stat reset.
She loves it as-is so flashing roms is out of the question. I don't have time/she doesn't have the patience for me to flash roms and fix problems that arise. With that being said I would like to explore the other back-end options.
Now, keeping in mind, this dinc is completely stock. Stock sense, stock kernel, stock radio, etc. I've been advised to replace the stock radio with one from Doug Piston. I was told to install the 04.08 version for the EVO. I just want to clarify that this will work for the Dinc running stock froyo sense? Also, if someone could tell me exactly what this does? Is the main benefit better battery life? Or something else? Also, if this is not the correct radio I should install, which is?
My second question is in regard to a better kernel. As stated above, I am stock and will remain on stock sense. What are some good proven kernels that will work on stock sense. Performance on the device is fine, so I'm not worried about that. I'm only looking for a kernel that will boost battery life. I looked around here but I couldn't determine which of these, if any would work on a stock Dinc or if they were just for custom roms?
Anyway, that's all. Thanks in advance for any help on this!
Here is a link to all the different kernels that are available for the Inc. It will say if it works with AOSP or Sense. Just take a look through them and see which one would work the best for what you want. Some will overclock, some will underclock, etc
http://forum.xda-developers.com/showthread.php?t=866736
Whoops didn't notice you had that link already. Some popular ones are incredikernel and heyitslou. I know with incredikernel I was getting good battery life but also was with different ROM not sense.
I have installed a radio on my Inc, been quite fine for the last few weeks as well. From my understanding, the radio may or may not improve gps lock and/or your phone's signal strength depending. This is hit or miss, not everyone notices a stark improvement in both or either category. As such, if you already have poor signal in your area it may not improve your signal therefore it has no effect on battery life.
Someone more knowledgeable in that area please correct me.
You can try whichever radio you desire, I recall many people using 4/08 or the 11/19. Personal preferences aside, your improved battery life depends on how much signal your phone reports that it is receiving.
I have used the heyitslou kernels and have loved the battery life I got with it. I have also upgraded my battery to the 3500mA battery. This did wonders
incredikernel w/ smartass + CM7 and never look back...i know you like the ROM but i think stock sense is what drains the battery the most.
I've had good luck with Lou's kernel running a sense rom.
may want to try Virtuous v3.2.0 its a good stock rom with some clean-up done.

[Q] Rooted and poor battery life

As one of the primary allures to rooting is better battery life, I'd really love some help from the experts out there.
Background: Way back when the original Sprint Lovers ROM was supported and updated, I used that in conjunction with one of Netarchy's 4.2 kernels and all was glorious. I easily got 2 days on a single charge. After that ROM stopped being supported, I went with Myn's Warm 2.2 and ever since then, I've had mediocre battery life (get about a day on single charge). After Warm, I went to Synergy and finally, I ended up on Swagged Out Stock. I've tried various kernels...ChopSuey, Freedom...all to no avail. I hardly doubt I would have that bad of luck trying so many combos of ROMs and kernels, so I'm pretty certain I'm missing something.
I'll try to cover as many bases as possible to help troubleshoot, so if I miss anything please lmk:
- light to light-moderate user
- no live wallpaper
- usually max signal, maybe 10% is between 3-4 bars
- "Mobile Data Always On" unchecked, auto sync only on gmail, weather and news are manual syncs
- not the awake lock problem (21h since last charge, display is at 34%)
- have reflashed ROMs multiple times
- tried ChopSuey's kernel, lithid's aggressive and less kernels
- correctly recalibrated batt stats multiple times and anytime I flash a ROM/kernel
- 245Mhz-998Mhz, interactiveX, cfq scheduler
- in SystemPanel, nothing is taking up a significant amount of CPU space
- battery had light swelling so Sprint gave me a new sealed one a few days ago
Currently, this is what my software looks like:
Baseband: 2.15.00.0808
Kernel: 2.6.35.10-Freedom-v0.9+
SOS RC2.2
4.53.651.1
PRI 2.15_003
PRL 60681
I think that covers everything. I'm willing to sacrifice my first-born to get get back 2 days on a charge Thanks!
Get rid of Sense = more battery life.
Maybe try UltimateJuice from the market too.
You mean going to AOSP?
I understand AOSP ROMs in general have better life than Sense, but as Sprint Lovers was Sense wouldn't that be a moot point?
I never got to 2 days with battery life but if you want to stay with sense try freedom aggressive with clock speed 245-768 interactivex but AOSP does give much better battery life
Screen timeout =15 seconds
Gps off
3g off when not used
Brightness as low as you can having while still being able to see

Truth is, since GB came out, battery life is just not the same as Froyo. I, too, went 2+ days on the Froyo Sense ROMs I ran, with Netarchy SBC Kernels, but there is no SBC for Sense now, for one thing, and there newer versions of Android plus the Sense 3.x ports just use a lot more resources.

Sense in general is more of a battery hog than aosp. I can go 2 days plus on CM7.
Mikg plus aggressive is by far my fav against myns on sense. I easily doubled the life of myns. Slightly less than 2 days.

Hm, perhaps I spoke too soon. Maybe the new battery is helping or something because this is the best batt life I've seen since I flashed Warm 2.2 (did this around August or September of last year). Keep in mind that the batt I swapped out was somewhat swollen.
20h 7m since last charge and still @ 72%. If I'm not mistaken SOS comes with Freedom Less so I'm gonna try Aggressive and see how that pans out. I did not know that GB was that much more a resource hog than FroYo, so that was interesting to learn.
Keeping my fingers crossed -- thanks for the replies.
hmm glad to know its better...I had a question, i dont know if this is considered hijacking a thread or anything i'm sorry if it is, i couldnt seem to open my own thread lol...but its the same topic..
I rooted my friends evo and flashed it with koni elite 3 rom and netarchy toastmod 4.3.4 cms......the battery life was terrible even worse then when it wasnt rooted... so i thought maybe i didnt flash the kernel, so i went into recovery wiped davlic cache and cache and flashed the kernel...then i fixed permissions...but still terrible battery life..do you think itll get A LOT better after calibrating the battery? or that there is something else wrong with it?

Everbody and their mother says to delete battery stats. Lifehacker just linked an article a few days back that said that battery stats.bin delete is actually counterproductive.sense I stopped deleting it my battery is getting better and better..
Example; I have been tapatalking for about an hour now and it has been at the same bat level the whole time. Apparently it takes any a week or two to settle in the OS after the last erase.they also said the most likely reason to delete are new phone(as a baseline) or new battery. Lots of opinions but this tip is helping me...

[Q] CM7 Modem- does it matter?

A liitle background:
I ran BonsaiRom with the EB13 modem for months.
Battery life was great. 3+ days with the "fat" battery.
I've tried 5 or 6 different roms since the sprint GB upgrade, the first of which preferred the EI22 modem so I "upgraded" to EI22.
Since flashing the EI22 modem, battery life is terrible. It may be due to the fact that I live in a low signal area. Battery stats confirm that most battery usage is for phone signal.
I'm now running CM7 and plan on sticking with it. (Is CM7 great or what?)
So my question is, will CM7 work with EB13 even though EI22 is recommended?
btw I've seen signatures in these forums that show people running CM7 with other modems. I'm sure I'll try it anyway but I'm just curious as to you guys experiences.
Yeah, I'm pretty sure the modem is independent of the ROM even in cm7. I'd try using the modem that works best for you in your area.
There has NEVER been a rom that needs a certain modem. Bonsai did, I dunno why though. It should've worked anyway.
sent from my always aosp epic
Thanks for the info guys!
Over the next week I plan on cycling thru different modems to determine the effect on battery life.
