Troubling trends with battery Life on DL09 and DJ05

[Kamar234]

I have enjoyed using kernels from geeknik, jt and Adrynalyne and have been using them since I picked up my Fascinate since September. I have been using this phone along with juice defender and juice plotter as well, an it has had a great impact on battery life. One thing I noticed back on Di01 was that the standby on this phone was phenomenal. There have been time where I have only lost 3% over 12 hours with the combination of juice defender. However, since I have upgraded to DJ05 and DL09, it would have the same standby for 3 or four hours then precipitously drop 10-15% on standby in around a half an hour. I notice this on juice plotter. I was wondering if anyone else has noticed this, and if it may be something with this rom or a particular kernel. I am running Adryn's 12/30 kernel and I have tried jt's kernels and stupidfast when it was being used as well. I also used Adryn's 12/16 and 12/17 voodoo kernels with no difference. Any takers? I am also apologizing for this being posted in development. Was jumping on tabs between development and general and put this in the wrong section. It's kind of late.

Try a cache wipe and wipe the battery stats too in cwm the kernels themselves are fine and the undervolting will give you better battery life than not

Has to be your phone or battery.
I'm dj05 voodoo with juice defender, on standby for over 3 hours I well lose at most 1%

Newb question. What is considered standby? Hitting the power button thus turning the screen off and locking it?

Yes.

I have done the battery wipe, but not with the cache. I don't think it's the battery because it was working great before. Had two fascinates with shot batteries and I know the difference haha. I'll try the combo of cache and stats wipe. I thought it was strange too because there should have been nothing short of the screen on full blast and a demanding game that could make the battery draw down like that. I'll give it a few days and see what happens. Thanks for the replies.

You and me both brother. But I don't use juice defender. I'm actually resorting to turning off data to save battery once school is back in session.

 

[Kamar234]

I hear ya. What I love about juice defender is that it keeps the data off most of the day and pings the network for data for one minute every 15 or whenever you want it to. I was doing great on it before. I recommend it pretty highly... unless it is actually the culprit for my battery drain haha. I was using doubletwist, but noticed in the logs it was using 45% of my battery some days without me even using the app. Keep a lookout for that everyone. Not an app you'd expect to be doing that.

I am having the same battery issues. I don't think it started after my bump to DJ05. It was definitely the worst when I ran StupidFast 12.20, after rolling back to StupidFast 1.56, it improved a lot. Still not as good as it was in the before time, in the long, long ago.

I did wipe my batt stats, but not my cache, so please let me know if that makes a difference. Battery life is everything.

Well, I'm DJ05 and voodoo, and have had a terrible battery life ever since I upgraded. I just installed juice defender and ultimate juice this morning, and in about 3 hours, I've lost about 12 percent battery... that's with moderate usage, so I'll keep this going and see whether it actually lasts to the end of the day.

Update:
Well, it seems to have actually helped a decent amount... while my phone was idling for about 5 hours, I lost about 5 percent battery. But, under heavy usage later tonight, it went down a lot faster. So, for anyone having these problems, these two programs seem to help, at least while idling.

Experiencing the same issues. Yesterday I went from 76% to 38% in 5 hours with moderate use. Before DJ05 I used to be able to get atleast 15 hours of moderate use on a full charge. Now I get about 10 if I'm lucky. I've tried various kernels. I used to run geekniks on DI01 with no problems. Thought it was voodoo, but since have removed it and am running geekniks 1.54. Not sure what's going on. I'm wondering if it is because I am using the stock DJ05 w/ certain apps removed......

edit: Since unplugging from car charger not even an hour ago, I've lost 11%! I've used my phone just to do about 10 minute Google chat and gotten about 5 emails. I'm almost tempted to go back to DI01......

edit: Unplugged at 10:30 from car charger and now at 31%! this truly sucks. I won't be able to last a day with the phone like this. May have to go back to DI01 and put up with the GPS.....

I have noticed the same since I went to DJ05, what I am running is in my signature, I noticed the other day I was watching a movie with 54% batter left and 1hr and 30mins later I was down to 15% batter power left... is watching a movie that demanding? My screen res is as low as can go on the stock adjuster,

 

[Kamar234]

Well I unplugged at 6:30 and I am 75% and it is 3:25. Not that bad, but from 7:30 to 10 I went from 93% to 80% all on stand by. Then 8 went from 80 to to 75 from 10 to 3:25 also on standby. Makes no sense really. It seems to just have random times where the phone just eats battery on standby for no reason. It does tempt me to downgrade and yes, this is not official for a reason. I wish there was something that could be done about it. I don't want to give up my Gps

 

[johnnyv5]

I don't want to give up my Gps

this is the only reason why I wouldn't downgrade. Also, with my luck, as soon as I do downgrade Froyo/Gingerbread is going to come out and then I'll have to do this whole data wipe thing again !!!!

My battery has drained 21% in two hrs with low use and juice defender...wow

I thought I was going crazy. Good to know others are having this issue. Saved me from wiping my phone and trying another ROM. Hopefully someone more knowledgeable can chime in and find the culprit.

My phone was down to 9% at 8:30 with pretty light usage. I'm hoping that there is something in the new DL05 build that will help with this. DL05, for me, has been having lightning quick gps lock ons. As quick a my og droid was actually. I just can't give that up though. I have been tracking this for a while, so I was curious to see if others had the same issue. Glad to see that I was able to bring this to people's attention.

My battery sucks as well no matter what I try with DJ05 or DL09.

I'm even running Voodoo5 125mv under-volted

I had absolutely terrible battery using the Stupidfast kernels after 1.54. It seems like most posting about poor battery life are using one of his kernels. I switched to Adrynalynes 12/30 and have MUCH better battery life. Maybe 2% per hour loss on standby and went about 30 hours with moderate use. I suggest you guys try this kernel or JT's.

Edit: Just FWIW anytime you use the GPS the battery is going to be raped. I think I used about 30% in less than an hour while geocaching. I was really shocked.

 

[bradlove17]

I am seeing the same thing as KenKeno. The stupidfast kernels sucked my phone dry so I gave up on them back in december. I'm using JT's 12/30 and went 35 hours with light to moderate usage. I don't use juice defender or anything like that either.

One other thing I noticed about the stupidfast kernals was that they tend to slow down the longer you go with out a reboot. Jt's kernals don't feel like they do this. So, maybe just give jt's kernals or adrynalynes (just an undervolted version of jt's kernal) a shot, they feel just as snapy to me. boot times maybe a little longer but that doesn't really matter does it?
