[Q] Kernel Help

Right now I'm running H57 with JT's 4/15 voodoo kernel. For the past few weeks my battery life has been miserable. I've tried several different Kernels, wiping, data, cache, dalvick cache, and battery stats. Ever since the bad battery life, I've noticed that the Android OS is consuming much larger battery percents than it used to 30-50%. It used to stay around 5% or less. Also I been using CPU spy for a couple weeks. My CPU seems to spend almost all of its time at 800 Mhz for some reason. It will not power down to 100 Mhz even if I turn it on and leave it in my pocket for a few hours. Today i've burned 80% of my battery in 5 hrs while it sat in my pocket during an exam. Any advice on what I can do or check to see what exactly the problem is?

Im not quite sure what the issue could be but I can suggest a program called osmonitor that might help you narrow down what rogue process is eating away. i recently just upgraded from 2.1 to 2.2 as well. I am running JTs 4.15 voodoo kernel. My battery seems about the same so far as 2.1, maybe something with H57 ?

Yeah, I can try another rom. It was happening prior to H57 though. I've been on 2.2 for a while now. 2.2 was running great at first. It happened while on PNP. At first it was amazing on battery. I don't remember changing anything specific to ruin my battery life. To the best of my knowledge it occurred after flashing OTB on PNP. I'll download osmonitor and see what i can find. Thanks.

I'm pretty much stock / rooted w voodoo and about same as eclair check the misc section in osmonitor for cpu scaling

Here's a screen shot.

Er you're roaming?

Yeah, I'm pretty much always roaming. No USCC in Raleigh where I go to school. The only time i'm not is when I go back home, which is not a whole lot anymore.

That is likely why your battery life sucks. The phones is constantly trying to find a better signal. Also, USCC doesn't always enforce this but they do have a clause in the contract that they can shut down your line for using it more than 50% of the time outside of their network. Just something to keep in mind.

Yeah, I've heard that, but I've had uscc up here for 3 years now. It used to be fine up here. I've had it in raleigh for 6 months and it just start acting up about 2 or 3 weeks ago.

And the answer is no. I charged the phone over night. Left to fish at 5:30 this morning. Unplugged the phone and turned it on when I left, turned off tasker just to be sure that wasn't causing the issue, and left the phone on the table at home. Back at 3:30, phone at 35% not even using it. I can't find anything using osmonitor. When I look at it, osmonotor is usually using the largest amount of resources.

Battery life is not something people can fix for you, there are too many factors that affect it, u just need to troubleshoot. I've had various results with different roms but typically it is your usage and the apps on your phone that are culprit
Sent from my SCH-I500 using XDA Premium App

I completely understand that. That's why I spent a couple weeks troubleshooting to try and find out what the problem was. Like I said I can leave the phone on all day and never use it and the battery still sucks, so It's not usage. I can not find any apps that are consuming much battery. The only thing I changed between good battery and bad is from JT's voodoo kernel to OTB. Android OS and System began to use 60% of the battery and a 5 minute phone call will burn 5-10 %. I said that sucks, switched back to JT's kernel problem still persists trying different roms and kernels. That's why I posted this to see if something could have been messed up when flashing to OTB.

[Q] Zapping and Extended Life Battery... should I root?

Hello All,
I've got a Droid X with the handy and convenient one-click root method Z4root. However, my wife's Droid Charge is an entirely different story. So far I haven't rooted it because I'm hoping to use that as a last resort (I don't want to brick her phone).
She was having some trouble with battery life, so she bought a Samsung extended life battery. Instead of her phone dying within 4 hours of a full charge it could make it pretty much all day. But this week all of a sudden, even with that, she's back down to 6 hours, if that.
Early on when she got the phone I downloaded Advanced Task Killer for her and gave her some basic tips (low brightness, no mobile data, etc.), but I'm at a loss. I'm not sure if it's the GB update or what. I'm almost ready to root her phone and roll it back to Froyo because I think that's part of the problem, but I'm at a loss. Do you guys have any suggestions? Or is rooting, battery calibrating, and cleaning out bloatware my only option? I'd appreciate any help. Thanks Droid experts!!!

Don't use advanced task killer first of all. It will probably reduce battery life. GB update has made the battery better in all situations.

Whether or not to root is really up to you however if you do decide to root it is actually quite easy to root EP4D(the latest OTA update). Here is an easy to follow write up that I did:
http://forum.xda-developers.com/showthread.php?t=1434738
Personally I rooted my phone and I have loved it. When I was using stock rom debloating did help some with my battery life. The biggest difference I found however when when I flashed eclipse and imnuts pbj EP4D kernel on to my phone. Eclipse is an awesome rom that is already debloated and has been tweaked to run super smooth. Imnuts pbj kernel has lots of great performance and power saving features(for example the ability to undervolt). Running stock I would get about 8 hours of moderate use from my standard battery(1600mah) and 4 hours of heavy use. Running Eclipse with imnuts kernel I get 18-20 hours moderate use and 8-10 hours heavy use.

calibrating the battery would probably help. id check to see whats running; gps, wifi, bt, etc. also it could be a rogue app that is sucking up all the juice. juice defender could help and if u have no use for location apps u can go into setting/location and turn off stand alone gps, google location, and vzw location. but def root the phone and put a custom kernel and rom on the phone, there will be a big difference.

I find that Facebook often runs rampant and needs to be told to stfu constantly. Also, a custom kernel with aggressive undervolting will help too.

Best rom on battery saver

Does any one know what is the best rom to save more battery or the best kernel. Now i have gb 2.3.6 here is an screenshot
Sent from my SGH-T959V using Tapatalk

Look at the guide in the first link of my signature. The ROM's listed (icbinb included) coupled with AntonX's kernel and one of the tweaks, I think, will give you the best combo available to us.
Remember to keep wifi and sync off when not using. Use Gemini App Manager or similar app from market to stop apps from unnecessarily starting when you don't need them to. If you don't use wifi calling remove or freeze the app along with other apps you don't use. Read about undervolting your phone. I feel like that has helped me.

Thanks a lot...

I run the latest version of Valhalla black(not FB) and I can get a day's use no problem. Looking at my phone now, it has 8 battery left and is at 18hr 41m. This isnt right as I took it off the charger at 8am this morning and its 2:30am now. Hasnt been on charger since, so thats pretty good in my book. I leave Wifi on, but it only connects when I'm home. I did a full shift of work, 8-5 on 4g. Heavy texting, some web browsing and small time on other apps, downloaded some apps. Just all basic use of my smartphone. I never had to worry about the battery on this rom. Use the music app to play music through my car during commute. Yeah, this is what I would suggest to use as a rom. I have been on Valhalla for a few months now. Only thing that is weird is random reboots. Which only happen... maybe once a week. It doesnt affect anything, well, not anything to my knowledge or the basic use of my phone. So yeah, results may vary but give it a shot!

Thats pretty good.... I charge my phone two time a day... May be bad battery.... But i think that i need to change my rom first...
Sent from my SGH-T959V using Tapatalk

I'd say Hebrew Valhalla with atonx's latest kernel and undervolting has had the best battery life for me. I can easily get through the whole way with moderate to heavy use while still having 50% battery left when its time to go to bed. As long as you don't change the localizations, its completely in English so think of it as Valhalla final but updated. I love it!

Have you tried going back to stock with Odin?
Not sure if your issue is the same as mine, but after I went back to stock it seems to have corrected the issue. It still seems to warm up a little when I'm using it a lot (playing a game, looking at the LOL Droid app, but not, oddly, playing a video) but the battery issue seems to have been solved.
I know that using the phone is going to make the processor run faster, and that faster processor speeds can definitely contribute to heat build up. Do you have a case? If so, take it off. If not, maybe give the phone a break every now and then? I don't know.

You never know...it could be the weather around here
I would install Better Battery Stats (if you don't already have it installed) and monitor it for wakelocks to see if something is preventing the phone from deep sleeping.

Best Batteries or Extended Batteries

Hey guys, would love to get some advice on batteries for this phone. I would like to buy an extended battery or at the very least a spare that I could swap out when my main one dies (which happens far too frequently for my liking). I've heard some talk on these forums about Nexus batteries fitting in these phones, is that true? And if so what Nexus battery should I purchase to be sure it would fit? If not any aftermarket batteries that you guys recommend or would I be better off with OEM? Thanks in advance for the advice!

I'm using the latest 'stable' build of CM10, CM 10-20130107 and whatever the default kernel is for that ROM. Battery life isn't awful but I wouldn't really call it great either. If I'm just around the house on WiFi all day I can get about 3 hours ish of screen on time and maybe 10 hours of standby. Problem is as soon as I go mobile 4G seems to really suck the battery dry. I'll get maybe an hour and a half of screen on time and shortly after that it will die. The strange thing is that I have all of my push notifications off for everything except Facebook, no email or any other apps are seeking data (in theory), Google Play isn't allowed to update when on mobile data so I'm not sure why being on 4G makes such a difference but it really seems to drain the battery fast. I have noticed a few things when trying to troubleshoot battery issues that I've had, CPU almost never seemed to go below 384 MHz according to CPU Spy so it was never hitting deep sleep like it should. I went ahead and uninstalled almost all my apps on it and now it does seem to enter deep sleep more often. Another interesting thing that I notice is that sometimes the phone will just be sitting in my pocket not doing anything and it will be really warm for some reason (almost like CPU has been working under full load for a long time) even though I haven't been using it at all. Seems to only do that when I'm not on WiFi so maybe something to do with the 4G modem? Anyway if you have some advice on a better ROM or kernel that would give me better battery life I would be happy to hear it. Battery life is really my only gripe with this phone.

I'm using the All-star Liquid Smooth ROM and running Lightning Zap Kernel by Thomas.Raines
This is my battery life
Now I have been using WiFi all day and when I'm on 4G there isn't a significant battery drain... to be honest I saw some of the best battery life ever on this phone using AOKP by racing 19969 I was getting at least 15 hours and max was 17.5 hours using LZ kernel on that one too
Sent from my SAMSUNG-SGH-T769 using xda premium

I've been able to pull about 12-13 hours with minimal use on CM 10 w/ BlueLightning X2 kernel underclocked a bit, so I'm thinking its time for a new battery. When I first got it I was able to get somewhere around 16 hours on the debloated stock GB ROM. Ideally I would love to be able to get at least 18 hours, so that I could make it through an entire day and night with a few hours to spare, but I don't see that happening.
I love this phone, but hate having to worry about the battery mid-way through the afternoon. I really do miss the days of my old BlackBerry getting 3+ days of heavy use before it started to warn me to charge it...

I've honestly thought about going back to stock firmware several times, thinking that the battery might be better there along with better stability. I love CM-10 for the looks and just overall usability but with random reboots still happening at least once a week and other little quirks along the way I've wondered if I might not be better off with something a little more consistent as my daily driver. I did try Lighting Zap Kernel at one point, perhaps problem with how my mod was installed or something but I found my phone to be consistently slower and laggy with it so I removed it and went back to base CM-10 kernel.

Well the thing was I only lagged when I had Lightning Zap installed so either it was stupidity on my part or too much gunk in the file system or something else. I'm a little confused as to what AOKP is, I was under the understanding that it's a kernel, but Lightning Zap is also a kernel and you can't have two right? I did try the Gremlin Remover, which completely screwed up my phone the first time, so I went back, used black hole, then Gremlin Remover, and reinstalled everything from scratch, phone seems to be stable now but I did have a black screen on death once since then. Somehow in that whole process my 32gig SD card seems to have died : (

I would use the latest nightly instead or the stable. I also use blue lightning x2, I have better batterywith it than with Lightning Zap. Using mobile data with the screen on will kill your battery no matter what.
If your phone is not sleeping correctly (normally I will loose 1 percent a hour on wifi while sleeping, I also do a high level ATK kill before). Try doing a backup and run black hole and fsc a few times and format the emmc (backup important stuff). Then a flash of the nightly, kernel and gapps.
