[EVO 4G Android Development] EVO-lution of Man:
Flashed #4 last night and loving it. 80% battery after 15 hours. Mostly sleep time with about an hour awake. GPS and wifi on for an hour straight. Really good so far. Using stock battery too.

Spoken into my EVO cause I'm probably driving
[EVO 4G Android Development] cb7tuner93:
And After Overclocking
[EVO 4G Android Development] cabbieBot:
#4 dropped quadrant below nexus2.2. it was higher on number 3.

I also notice I'm getting 4g signal in current areas as I'm switching through these kernels. odd. each seems to be different
[EVO 4G Android Development] jasongthang:
I have a novatec screen, running fresh 3.1.0.1, soon to be fresh 3.1.0.2, which of those downloads is right for me?

I don't get the differences between cfs and bfs, so I don't know which I should download.
[EVO 4G Android Development] drdrewdown:
same config here, pretty happy with #4 bfs
[EVO 4G Android Development] BAleR:
Has anyone had the phone lock up on them? Like when you come out of the lockscreen after it had been asleep for a min? Its like its stuck at 384mhz or somethin. Gotta reboot to fix?
[EVO 4G Android Development] jasongthang:
ok i downloaded it, 3.6 mb file correct?

and I can flash this through RA recovery just like a rom?
[EVO 4G Android Development] akarol:
Definitely not at fast as BFS #3 but the battery life is ridiculously better.
[EVO 4G Android Development] halorin:
Yeah. You'll want to wipe cache and dalvik cache before you flash, though.
[EVO 4G Android Development] Jsimon9633:
King if I don't care about anythiimg but performance which one of your kernels should I run
[EVO 4G Android Development] Iceman5000:
I Agree #4 is not quite as smooth as #3 but battery life is unbeleivable!!!! Normal use, lots of wireless teathering with 4G and after 10 hours I'm at 61%. This kernel is the Toyata Prius of kernels. Great Job.!!!!
[EVO 4G Android Development] akarol:
Well, since we seem to have more play with battery life with #4. What SetCPU settings are you guys using with it?!
[EVO 4G Android Development] gmelchert:
hahaha I just got 1337 on quadrant :D
[EVO 4G Android Development] dumfuq:
fyi the link in your op to your github, does not take one to your github. :)
[EVO 4G Android Development] Iceman5000:

[EVO 4G Android Development] rockky:
Got my best Quadrant score ever: 1575 on #4.
[EVO 4G Android Development] godfirst:
1614 with #4:D
[EVO 4G Android Development] Stunna4life888:
Im glad someone is getting good battery lol. I don't know what killed my battery today but with light usage i got 5 hours at the most and when I mean light usage im talking it mine as well had been off lol. But android system was at like 50%. Something is pretty much causing my phone not to sleep and I cant figure out what it is:confused:. I know voicemail update may be one thing. I can't seem to update the thing from fresh. Would the battary percentage widget from HTC kill is that fast as well? Hoping someone maybe able to point me in a good direction. Thanks!!!
[EVO 4G Android Development] pongoface:
Download system panel and it should show u what app is running and eating the battery. It is not the kernel some app is chewing it up.
[EVO 4G Android Development] robpet2:
im gonna give the #4 combo a try.. def need better battery life.. just flashed it and then reflashed the orig fresh 3.1.0.2 rom after flashing the kernel and still got the FRESH boot up sound.. yeah it was kind of low but gotta see how the battery performance is.
[EVO 4G Android Development] bluefire808:
No matter what i did to try and fix it i would get errors of some some sort and force closes in the gallery with #4 i did a cache wipe and dalvik. No dice. Even did a wipe of both agai and installed #3 and the problem persisted. I had to do a nand restore to solve the issue....
[EVO 4G Android Development] tj gamino:
Installed juice defender and wiped my battery stats.. and im seeing an awesome increase in battery life.. also I have setcpu installed oc'ed at 1152000.. and im getting benchmarks in the 1500's.. very happy with this kernel.. im changing my sig as you read..

King is the mann...
[EVO 4G Android Development] evohog:
The voicemail update is in fresh updater. I just successfully flashed it manually in clockwork.
[EVO 4G Android Development] xtkxhom3r:
does 4g work with this i dont have 4g right now but i dont know if its because of the kernel or something with the rom....
[EVO 4G Android Development] eniamg02:
Yes 4g works
[EVO 4G Android Development] enigmatl:
Ok. So what is the difference between kernel #1, 2, 3, ... 7? I get that there is a bfs and a cfs choice. And I see the changelogs for the kernels. But say you want to download a CFS kernel, what are the differences in the choices of kernel (and for the different BFS kernels as well)?
[EVO 4G Android Development] rjmjr69:
If you read then why are you asking lol? Read thru a few pages then search google. Your going to get torn apart man sorry....

Basically they are governors
[EVO 4G Android Development] enigmatl:
Okay. Any non impolite replies please? There are like 7 kernels from this build, some of them are for cfs and some are for bfs. That, I don't need explained. What I do need explained is why there are multiple choices for the CFS and multiple choices for BFS. And, as a NON noob, I didn't see that clarified. There are changelogs for each kernel but that doesn't tell me how each of the CFS kernels differ and how each of the BFS kernels differ. If this info is out there somewhere, can someone please provide a link? Thanks.
[EVO 4G Android Development] EtherealRemnant:
You're a retard if you can't start from the change log for the 1st kernel and work up... the BFS is made off the CFS kernel... Pretty much development on CFS seems to have stopped at 7 and then been switched to BFS for all further development.
[EVO 4G Android Development] bluefire808:
I cant tell if it is actually the kernel or the Saphire theme im running. So i got rid of the theme to see if it really is the kernel. Ill report back
[EVO 4G Android Development] felacio:
I was about to comment with a less rude version of what Ethereal said.. but.. he got it pretty right.. lol.

Really, read the OP. It explains exactly what's changed. A better question, if you don't understand all the mumbo jumbo would have been "which does everyone prefer"?

...in 1943, I killed a drifter.

[EVO 4G Android Development] Rippley05:
Battery life being so "great" on BFS 4 is a bit of a stretch... seems average to below average to me.. maybe 8 hours or so.

Think I'll have to go back to a plain jane version of netarchy unfortunately

Violation Of Forum Rules

What part of Forum Rule #2 wasn't clear to you?

I certainly hope this isn't the way you speak to family, relatives, or an employer. By showing respect, you encourage collaboration which in turn reduces the number of off-topic, flamming, and trolling that goes on in the forums.

I remind all members that there are two options when visiting a thread:

Option 1

Provide an answer to the question in a courteous and professional manner ... not "use search", "use google", "go back and read", etc.

Option 2

Move on. If one is not inclined to respond in a constructive and helpful manner ... don't!

Really?
[EVO 4G Android Development] robpet2:
I'm gonna test the battery life today. I forgot to plug my phone up last night and got 7 1/2 hours and lost like 20 percent battery life.

Sent from my HTC Evo 4G
[EVO 4G Android Development] abanh:
How much usage during that time? It shows android usage at 2% so it doesn't look like you used the phone that much.
[EVO 4G Android Development] hooover:
obviously not!!!....:rolleyes:
[EVO 4G Android Development] Biofall:
Haha ha .. ha. Ohmygosh I love posts like this. JG... listen bro. I'm really not trying to be disrespectful, but with one day of usage, have you had your phone sitting in the fridge all day?

Maybe you don't understand what people want when they say good battery life. Obviously tons of people don't, because every day I see posts exclaiming of their amazing battery life with what most users call light usage, but the few call a miracle. Please explain to these bewildered users that you barely, if at all, used your phone during that time
[EVO 4G Android Development] asesino:
I believed that's what he did.
[EVO 4G Android Development] JG-1:
Used for moderate amount of texting, a few calls, and listened to 2 hours of mp3 while on the treadmill.
[EVO 4G Android Development] Biofall:
Ah thanks for the explanation. By xda standards, we would call that light usage. Not very light, but sure not medium.
[EVO 4G Android Development] JG-1:
Hey, I didn't claim the phone was used heavily. After 24 hours on this kernel I only had 45% drain. Before, I would leave the phone unplugged overnight and I'd go from 100% to 70% in 8 hours....so I'd say this kernel is pretty damn good with battery life.
[EVO 4G Android Development] JG-1:
Yes, it was used pretty lightly (even my standards) yesterday...but still....the battery after 24 hours was still at 55% and that includes how the Evo's battery drops 6% in the first 10 minutes.
[EVO 4G Android Development] Biofall:
Yeah I've gotten over 48 hours with light usage. The only reason I commented was because you posted your OP in response to someone complaining about battery life, and the light usage you reported probably meant nothing to him.

I'm going to drop a bomb here. Guys, everyone wants better battery life. I want better battery life. But in all honesty, the battery is still the battery, and no matter what the kernel or the underclock, with the same usage, the battery's life will only change a few hours at most
[EVO 4G Android Development] twe90kid:
yup this kernel doesn't work for cyanogen
[EVO 4G Android Development] dmoses1969:
I would call this pretty good.

[EVO 4G Android Development] Biofall:
LOL :D :D :D :D

Look up about five posts at what everyone was saying before. In almost two days, you used you phone wasn't even AWAKE four hours. Anybody with ANY kernel can do that. That's what we call light usage, and though I'm glad you can do that, light usage data is kinda generic and useless to most smartphone users, who as the name suggest, use their phone.

Totally not attacking you, just trying to get the message across that you can't vouch for good battery life on <4 hours awake time with 30somethin hours up.
[EVO 4G Android Development] dmoses1969:
Really

I know that is what we call light usage. But, I don't think even the stock kernel will last that long with what little usage I had. My phone actually sleeps. With the stock kernel I would lose 15% battery overnight.

With BFS#4 I can have everything turned on including exchange email set as items arrive and I only lose about .5% - 1% per hour.
[EVO 4G Android Development] akarol:
Anyone experience sluggish performance once in a while when you reboot? It only seems to go back to normal if I reboot again. So weird. Totally random.
[EVO 4G Android Development] Jsimon9633:
Yes I have had that issue like when I swap my spare battery in. Seems sluggish and then I reboot and its all good.
[EVO 4G Android Development] akarol:
That's so odd. I don't recall experiencing that with any other kernel. Hmm... hopefully this won't be an issue in the future.
[EVO 4G Android Development] jasongthang:
Ok...so I just flashed the fresh 3.1.0.2 incremental rom and then flashed the bfs #4 kernel. Everything seems to be running ok, but I have one issue which may not even be an issue.

I never wiped anything before installing the kernel. I read all the instructions, etc., but i got so excited to flash it, I forgot to wipe everything first.

Is this going to mess up anything? Should I factory/dalvik wipe and reflash? Also, if I did do that, would the correct process be:

1. titanium backup

2. wipe everything (cache,dalvik, factory)

3. flash full version of Fresh 3.1.0.2

4. flash kernel

?

Also, I have the 1.34 pri, would this be a good time to install 1.40?
[EVO 4G Android Development] Biofall:
The only time to wipe is when switching to a different kernel maker, or if you have problems, but I do it every time. The order you listed is perfect. I'd go for the PRI after you do all the steps you listed, then make a nandroid backup
[EVO 4G Android Development] jasongthang:
thanks! would the radio and wimax be fine, or would i have to reflash those as well?
[EVO 4G Android Development] Biofall:
Nope! Everything in your settings>info>about phone>software information will stick until you flash something to replace it, so wimax and radio need to be flashed once, and then updated when a new one comes out
[EVO 4G Android Development] kingklick:
I'm still at the river guys

Glad to see it's stable still
[EVO 4G Android Development] Biofall:
Yeah I hadn't thought of that, with underclocking available you can maximize sleep time, you're right
[EVO 4G Android Development] bigheadwillie:
I dont know why i cant get the battery life that everyone else does, but i've tried everything. I have used both versions of this kernel, netarchy's kernel, hero's baked snack kernel. No matter what i end up with low battery warning by the end of my day. my day starts at 730am, and ends at about 1130pm.

With normal usage: 10-25 minutes of calls, using the htc news app (syncs every hour) about 1 hour a day, surfing the net abotu 30 minutes, about 10-20 texts, push gmail and exchange account with occasional replying, running rhapsody for both of my 20 minutes commutes to/from work, my phone will be at %15 by 10pm.

I have checked for any apps causing a wake lock in spare parts and havent found any.

For example, i am currently running bfs #4 of this kernel, with baked snack 1.4. I woke up and unplugged my freshly charged phone. I used it for about 45-50 minutes. my usage consisted of checking and replying to a few exchange emails, starting up and configuring custom car home, and messing around with google navigator. After all that i was down to %86! %14 battery loss in less than a hour wtf!

I have even tried conditioning the battery as suggestedby htc/sprint to no avail.

Any suggestions or comments would be appreciated.
[EVO 4G Android Development] jasongthang:
i think that might just be the "nature of the beast". i know navigator usually sucks my battery down pretty quickly. Its funny because whether im using the phone heavily or not at all, it usually drains pretty fast in the morning, from unplugging it at about 6am until around 11 it goes down about 20-25% without much use. After that, I'll have about moderate use and it will drop < 10% an hour. I usually end the day at around 15-20%. thats with texting, email, internet surfing, pictures, a couple calls, and music.

I guess a lot of it depends on your location too. I've drained my battery down to about 50% in 3-4 hours just because I was working in a hospital, or the back corridors of a mall. Whereas I've been in some buildings where after an 8 hour day, I'm only down to 75-80%. (I do fire alarm inspections, btw, so im at a lot of different places)
[EVO 4G Android Development] Biofall:
Honestly, you are getting normal to slightly less than normal battery life. As I've been trying to get across to people, all the posts about ridiculous battery life are just that: ridiculous. Those people put their phones in the fridge all day.

Here is what works for me for optimum life:

1. Buy something like switchpro off the market, and turn off all radios when you aren't using them.

2. Install SetCPU, and read this: http://www.pokedev.com/setcpu/

Using this, set up some profiles which can be found everywhere on this page, just search it, or pm me for details and examples.

3. Get rid of LP (I love em but they kill) and updating widgets.

4. Lastly, for that anecdote you told where you lost the huge percent in the first hour: That's a known issue. There are multiple causes:

a. The battery, when charging, get's to 100%, then stops charging to prevent damage. Once it slowly dies to 90%, it begins charging again, then repeats. This causes a drain because potentially you could take it off the charger at 90%.

b. Also, there is a thread in the general EVO forums talking about a trick to basically unplug and plug in the charger while the phone is off. READ THAT THREAD AND DO WHAT IT SAYS! It is confirmed working and will prevent the initial drop.

Do all this and you will get a couple hours increase, but like I've been saying, no amount of kernel underclocking or conservative ROM will turn your battery into a car battery.

Hope I helped
[EVO 4G Android Development] jasongthang:
very good post, helpful and polite. :)
[EVO 4G Android Development] xlGmanlx:
i have had the same questions. The big upgrade for me was juice defender. I tried all the set cpu stuff, and i eventually might install it back again to under clock,, but i loaded it, set my governor and then uninstalled. I can get about 10 hours now easily with my phone using juice defender and tweaking that. that and i plan on buying the sedio 1750 battery and their charger to alleviate hopefully the battery charging issues. even if it doesnt, it allows you to charge your phone plus 1 extra battery so worst case, use the fact that i can swap batteries. This is my work phone so i do a lot of email reading, phone calls, texting and using the web, so i guess it is just the nature of the beast
[EVO 4G Android Development] muncheroo:
In addition to what other posters have already siad, I've found that reception plays a big role in battery usage. If you have low / no reception it'll drain your battery very quickly.
[EVO 4G Android Development] bigheadwillie:
thanks for all your replies, but i have a few questions and comments about this reply in particular. First what is a "LP" referred to in item #3?

Also, i use the htc radio widgets and keep all radios turned off when not in use except for gps, since it seems to stay idel except for when a request is made of it by maps, navigator, etc. Is this practice just as effective as switchpro?

Lastly i have done the procedure of turning the phone off and unplugging/plugging it back in, powering it on/off as suggested in that thread. Do i need to redo this procedure because i have flashed new roms and radios and cleared battery stats since then?

Thanks again guys. i appreciate all of the help!
[EVO 4G Android Development] xlGmanlx:
LP = Launcher Pro?

"Lastly" I would highly suggest doing this any time you want to get as close to a "full charge" as you can
[EVO 4G Android Development] bigant262:
LP= Live Wallpapers
[EVO 4G Android Development] bigheadwillie:
Ok. I definitely dont use live wallpapers. Knew that would kill the battery from day 1.
[XPERIA X10 General] superleeds27:
had a problem with the market, created a secondary google account, this then allowed me to download the apps again as they wherr sticking at starting download.

anyway, it deleted all my contacts. i then imported.them from the memory card .vcf file. it imported names but.not.numbers to the names.

i looked in the vcf file and the numbers are with the names. any reason why it has only.copied names and not.numbers too, im back on my original gmail account. still not working!.

help pleasssseeeee cheers in advance!
[XPERIA X10 General] superleeds27:
also having problems wuth my original gma account. apps wont download from the market. gets stuck on starting download, i have cleared cache etc, but still wont work!
[XPERIA X10 General] GuestD2789:
there are a number of users on the official google android forums who are experiencing problems with their downloads stalling. Some users were able to download from the market again by simply logging in and out of Google Talk. Others had to do a factory reset. I also had this issue of not being able to download from the market, factory reset fixed it for me.
[Vibrant General] monksorlo:
Hello my fellow vibrant-lovers,

Just realized today that search button has stopped working,

I clearly recall that it worked before, as to when it stopped working, I have no idea. Since you can long press the left button to bring up search, it's probably not a big deal as far as practicality is concerned (I use the left button for search a lot of times anyways), but I was just wondering if anyone else has the same problem and whether there is a fix somewhere.

Could it be that some software or setting is involved??

I do have about 85 softwares installed, has a whole lot of widgets (they're amazingly convenient and are truly changing the way I use my cellphone).

Any help is deeply appreciated.

please do your jobs, be a smart ass and start with this one.. I dont care. Please clean out this section of the boards. Half these posts dont have a thing to do with development. Its a pain in the ass to try and sift over the posts here when they dont have anything to do with development.

Take your screen shot posts

your questions posts

your it dont work posts

your so on and so on posts out of this forum and into the correct ones

i say make another section for android hd2 general thats the least they can do for all of this , so the rom section will remain only for rom and released apps ....
[HD2 Android Q&A, Help & Troubleshooting and Genera] Ducter:
thats probably a good idea.
[HD2 Android Q&A, Help & Troubleshooting and Genera] mmafighter077:
I agree... android is so popular on the hd2... I believe it requires a whole new section for rom development" (if you want to call it that now), "Themes and apps" and "general"... if it doesnt happen now it should at least happen in the near future.
[HD2 Android Q&A, Help & Troubleshooting and Genera] Ducter:
any mods care to reply to this? I think its a serious issue and its against the rules of XDA..make me a MOD for a day, I'll clean at least this section up with swiftness :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] 11calcal:
I'm thinking someone needs to have less of an attitude, ok I know some threads are not totally necessary but to start being disrespectful through arrogance towards moderators is not called for & I take it frowned upon. Your better response to your issues would surely to direct your distaste to a mod directly instead of adding your own ill-appointed remarks.......
[HD2 Android Q&A, Help & Troubleshooting and Genera] Ducter:
No disrespect here. I am asking them to do their jobs, plain and simple. XDA is huge, I know it must be a tough job staying on top of all the posts here. I have run my own boards in the past and no where near the amount of posts..but keeping on top of them only equals a better experience for all. It makes searching easier as you dont get redundant posts, spread over numerous sections.

My reason for stating "start with this one" was simple, without that little line some one hear would inevitably say I am no different by posting here, in this section, with my added line I am saying I dont care if this post gets deleted, moved or what ever, start with this one if you want.

I come over here from the Nexus One section, prior to that it was the G1 section and am use to Mods that keep things clean and narrow..I just figured thats how XDA was in general.
