[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.

I'm going to be in uscc service for about 3 weeks here. I'll see if it makes a difference.

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.

CM7 MR2.5 bat issues

Hello to all you great people! I am not new to this site but I havent posted much or at all. This site is increadible and has taught me a ton about what a droid can do once you know how to use it. Thanks everyone! Anyway I have a question that I would of posted in the CM7 dev thread but I dont have permission since I havent posted much. Is anyone having bat drain issues with the newest build (RC1.1 MR2) using the GB radio 2.5? I have lost over 10% bat life in 25 mins while in airplane mode, no data including wifi and the screen was only on for maybe 2 or 3 mins. It may be a problem on my end but I just wanted to see if anyone else is having an issue with this. Oh and thanks to all you devs for doing all the hard work and dealing with angry wifes or girlfriends! We all appreciate it!

On mr2 it did feel like my battery was draining faster than normal.. with the stock kernel at least. Glad I'm not the only one try switching kernels
Sent from my Incredible using XDA Premium App

I actually had this problem too with the stock kernel, and once I overclocked with the Dream kernel it actually stopped draining my battery, strange.

I did try using Imoseyon's CM7 leankernel but had the same effect. Ill try the dream kernel and report back. Thank guys!!

I'm on my first day with this build of CM7, with MR2.5 and noticed my battery has drained way faster than it did with gingeritis.

Did you try wiping battery stats?
Sent from my ThunderBolt using XDA Premium App

Is there an official name for this kernel, or someplace to get it? I tried a quick Google search for "htc thunderbolt dream kernel", and it didn't bring up anything definite.
I noticed the battery drain too. CM7 7.1.0 RC1 with the MR2.5 radio. It seems to be "cell standby" that's using the highest percentage of the battery. I have it set to CDMA / EvDo auto.

What programs do you have running? Are you overclocked? I an running mr2.5 cm7.1 rc1.1 and still have 22% on 18 hours unplugged. 3 hour screen on, lots of texting, xda browsing, market updates, and an hour of plans vs zombies. On stock kernel, no overclocking. Using interactive governor.

I do have things set to run in the background, but they don't even register a high enough percentage in the battery usage to show there. I was not having battery issues with the 7.0.1 RC 6 on MR1 (the last build).

I've tried two of the utkanos kernels (not the OC one), and the dream kernel. On both of the utkanos kernels, I had no data. I tried rebooting several times, switching data on and off, and changing the network mode. No luck. The dream kernel took several minutes, but data finally came on. I haven't used it long enough to comment on any battery life differences between stock CM7 and this.

Running BAMF getting 1 1/2 on battery easy on 2.5
I am currently running the 2.5 on my BAMF sense 3 2.3.2 dream kernal. My battery is lasting very nicely currently. See the post below I have had better times the best was 1 day and 19 hours.

Ok so here's the news on my end. With the dream kernel things seem much better! However I was watching my ma usage and it went from 48ma to 240ma something after turning on wifi. Then after turning wifi off it never dropped. I rebooted and things went back to a cool 48ma. I'm guessing my original problem was with the stock kernel. But now that I'm on the new one the phone wont power down the wifi or something and made me burn thru my bat till I rebooted. Any ideas gents? Reboot did fix but that usually kills a good 4 to 10% of my bat everytime. I have next to nothing running in the background too.
Sent from my ThunderBolt using XDA App

Guess I should add that now after reboot I'm around 100 ma usage and steady with wifi on. Maybe a reboot once a day might do the trick till CM is finalized. Was thinking bout trying the mr2 radio stead of 2.5. Anyone know if there's a difference or advantage to either?

Unfortunately the speed test app doesn't work properly on GB roms so those results are most likely inaccurate. Try going to www.speakeasy.net and clicking on the speed test from the phone's browser.
After several runs through opera on speakeasy.net I'm consistently getting 15-17 down but still only ~1 up. Though it's much later at night so internet congestion is less than it was when I was testing earlier today, the EE4 radios do indeed appear to be somewhat faster. I haven't made any phone calls since I just flashed this a few minutes ago, the only thing I've tested is 4G data speed.
Interestingly, I seem to be getting better speeds by several mbps through opera than the stock GC 1.8 browser. Can someone else confirm this isn't just my connection flaking?

Does anyone else want this because of a crackling hiss and pop during phone calls on EP1X?

Yeah, I will give that a try.....
One other thing I noticed is, My phone is getting a bit heated. Current temperature is at 41 'C. I will keep monitoring the temperature tonight and see if its a temporary issue as I've been doing lot of speedtests now....

I was getting 7mbps down with the ep1f radios, but now getting 13 down wither ee4. Tested with speakeasy.

OK...so when I did the speed test on speakeasy through the phone browser I got 13 mbps (EE4 radio), and did it one more time to test and still got 13. I just did a test again but with wifi tether 3.1 b1 (w/infrastructure) on my computer and got 21 mbps (tested 5 times). I dont know whats going on.....

Thanks for all of the hard work kejar, I love gummycharged. How can we go back to the EE4 from the EP1F? Is it something we unzip and flash through odin, or can it be done through recovery?
Thanks!

unzip and flash through odin.

radio battery life
I'm running GB Eclipse 1.2 with baseband/radio EP1F , and I'm wondering if this'll improve battery life? Anyone notice improved battery life for this setup?

Seems to have helped mine somewhat. At work I am in a basement and before I was at -105 dBm. After flashing this I am at -90dBm. 4G Will not make it down here though

[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.

ROM suggestion

My fiance has had her charge for a while now and she is starting to get fed up with the battery life and lag. We have gone as card as turning off the 4g but she is still unable to make it through the day on a cullen charge with very little use. What rom would be best for improved battery life while maintaining the look and feel of touchwiz?
Thanks
Sent from my MB870 using XDA App

I would say your best bet is eclipse or tweak stock. Not really touchwiz but very great roms.
Eclipse thread can be found here
forum.xda-developers.com/showthread.php?t=1449643
Tweakstock you'll see in development section.
Sent from my SCH-I510 using XDA App

I recommend using eclipse or tweakstock for a rom. But you may want to just try imnuts custom kernel first and under volt the cpu. http://rootzwiki.com/topic/137-01-30-12peanutbutta-jelly-time/ That would improve the battery. If you're still not satisfied then try a rom with the kernel.

If you phone is ROOTED. You can download "battery saver" by Antutu from the Market(free) and try out for 2 days. This may help you with your battery without too much hassle.

What!! I'm running it right now with Tweakstock and PBJ kernel and it really really save me battery big time. I have tried to under volt, and turning off 4G, lower screen settings etc.. not help. Max I can get is 6-9hrs. After installed this, I hit 15 hrs normal use and 20hrs light usage. It controlled the CPU frequency and put my phone in very deep sleep. If I just make 1hrs of total calls and 20-30 text I can hit 20hrs easily. If I used Facebook heavily (65% screen on, about 3hrs total), I get 6-8hrs. Something is funky with your setup. During testing I uninstalled and reinstalled this app couple times and never any issue. Do me a favor while you're back to fresh stock, rooted and pop it back on see if it's working. I'm happy to provide screen shots if you don't believe me.
BTW, I have wifi,4g,gps on 24/7. While I'm in my house it automatically used wifi and when I'm out on the road it switched to 4g automatically. The samsung factory feature is working fine too.

Thanks for all the suggestions. I think I might give tweak stock a try
Sent from my MB870 using XDA App

The last few ROMs I tried, Tweakstock, Infinity, Gummy...all were very laggy. Didn't seem to matter what I did or how I did it. Camera was always a crap shoot on whether it would freeze up or not. I finally said the hell with it and went back to stock and then just plain rooted it. So far so good. It sucks cause I hate TW and the look of stock...but at least the phone is responsive.

Try Eclipse
You should really give Eclipse ROM a try. It is extremely smooth and fast....very responsive and the devs and community over at the site are very helpful if you run into problems. Yesterday, with light use, my phone was at 60% (15h 11m 25s on battery) at the end of the day. Best battery life I have ever gotten out of my Charge yet. Give it a try....you will not be disappointed.

Sounds more like something with the way you are flashing and/or your data restore. I would suggest that if you ever flash anything again you start from a totally clean slate
Charged up post!

I did flash from a clean slate multiple times, first few days the new builds seemed OK. After awhile it just got worse and worse. I've been on the rooted stock build for over two weeks and it still is pretty good. I'm done tweaking this phone, I'll have an upgrade option in May and then I will probably get the Nexus or wait a bit if something else worthwhile is coming soon.
