OK, I know the battery life issue for 4.2 ROMs has been beat to death, but I've got something weird happening with AOIP on my phone that doesn't happen with other ROMs.

Basically, when I'm at work, the battery graph (from Battery Monitor Widget Pro) looks like in the AOIPbattery image attached below.

As you can see, it ate all but 3% of the battery in about 11 hours. At times Battery Monitor Widget Pro indicated it was using the battery at 11%/hr or more! This is while I'm at work, and the phone is not doing anything, just sitting on the desk with the screen off, connected to a wifi network but not doing anything with that either.

After a few days of that, I decided I needed to try something else. Originally was going to go back to my "old reliable" backup of 4.1 Rootbox, then thought instead that I'd try the last build of 4.2 Slimbean I still had as a backup. Restored that and got all my current data for the apps reloaded, seemed to be working fine (though still had the stuttering and dumping of apps issues, which was why I wuit using it). Thing is, it's using battery not much faster than the Rootbox one did. See the SlimbeanBattery image to see how it did at work. Same scenario (sitting on the desk, connected to wifi, screen off almost all day). The little bit of high usage was while I was at lunch, reading some web pages and rss feeds, so the screen was on for about a half hour.

So, I'm wondering what the heck is making it use batter so fast on AOIP? I tried several things before switching to Slimbean. Airplane mode made no difference. Used Wakelock Detector to see what was using it up, and it was some part of Android OS making AlarmManager go nuts with wakelocks.

I even backed everything up, factory wiped it a couple times, then loaded the base AOIP 6/3 ROM and loaded GAPPS to see if it still did it.

Nothing seemed to make any difference.

In one sense, I'm hoping the new build that keeps getting hinted at might correct some of this, but I kinda doubt it considering how everyone who brings up battery issues usually gets treated. :(
[Samsung Galaxy Exhibit 4G] smartguy044:
That's normal for 4.2 Roms
[Samsung Galaxy Exhibit 4G] tazmaniondvl:
I see your point, why does one 4.2 room use that much more battery life then the other, it makes no sense to me. Maybe camcory can shed some light in this issue
[Samsung Galaxy Exhibit 4G] smartguy044:
That's how my battery life has been on all 4.2 Roms. If aoip is worse for you then most obviously you need to switch Roms.
[Samsung Galaxy Exhibit 4G] dwolfman:
I really was hoping that you would see that there might be something wrong with AOIP and take a look at it at least, and not throw out the same tired response. While I do appreciate the work put into AOIP, forum thanks have not happened due to the refusal to notice the glaring issue that everyone else does.

I would really like to know if you even read my post, Smartguy? Seems not or you would have noticed that AOIP in that scenario eats battery three times faster than another 4.2 ROM. Why?

I'm not trying to upset anyone, just trying to hopefully get this resolved in an amicable manner.
[Samsung Galaxy Exhibit 4G] Dvarl:
Some people don't have battery drain issues that bad with AOIP. You should keep in mind that this phone was never intended to run anything above gingerbread. Every one of these phones handles issues differently, which is unfortunate, but if a Dev doesn't have the same issue it is hard to address. Its just how it is.
[Samsung Galaxy Exhibit 4G] smartguy044:
Yes I read your post I wouldn't respond if I didn't. I have ran all the 4.2 Roms and with all of them I might get 10-11 hours of life. So no I don't see a problem with the ROM and if you do use another one.
[Samsung Galaxy Exhibit 4G] ArtfulDodger:
Wow hard to believe (well not really) this horse has been beat to death more times than a cat has lives! I'm pretty happy with battery life for the performance and OS I'm getting with AOIP. No hiccups and I have access to all the latest android features. The phone has a small battery anyway so if you want better battery life, time for a new phone or switch to a Gingerbread OS. I charge the phone once a day typically so that's hardly an inconvenience.
[Samsung Galaxy Exhibit 4G] dwolfman:
Thing is there is something major different in AOIP, as I can typically get just over 24 hours out of this battery in anything other than AOIP, including while I'm at work where the battery usage is a little higher than at home in every ROM I've tried (4.1 and 4.2 based included).

AOIP for some reason eats battery at more than 10% per hour only when I'm at work (less than 3% per hour at home) even when I haven't loaded any apps.

Every time I look at what is using it, it is either "cell standby" or "android os" that is using the most with the other of those two second and the screen usage following in a distant third.

I've tried to figure out what specific item in those two are the source, but it always comes back to some generic service or component in the os that is used by almost everything.

Really any advice to try and improve this, other than "use another ROM", would be appreciated.
[Samsung Galaxy Exhibit 4G] tazmaniondvl:
Try putting your phone in airplane mode while at work and turn on WiFi. That might help with eating the battery. Especially if where you work had a poor cell reception
[Samsung Galaxy Exhibit 4G] smartguy044:
get a new battery. i dont know what else to tell you. if you are getting 24 hours out of every other 4.2 rom youll be the only one. as i stated i get 10-11 tops on ANY 4.2 rom. so you have 2 choices new battery or different rom
[Samsung Galaxy Exhibit 4G] schuylkillparanormal:
Best thing to to is kill background data turn off Bluetooth WiFi sync and locations when not using your phone for a couple of hours. But your best bet would spring for an 2900mh battery.
[Samsung Galaxy Exhibit 4G] dwolfman:
That was the first thing I thought, but it acts the same.
[Samsung Galaxy Exhibit 4G] teerout:
im going to vote you get a new battery if its that big a deal....:good:
[Samsung Galaxy Exhibit 4G] detdett:
go back to gingerbread OS. we gave you suggestions already. 1) new battery. 2) gingerbread OS. simple as that
[Samsung Galaxy Exhibit 4G] dwolfman:
I just don't understand this. Why is it that everyone refuses to see that there might be something wrong with AOIP compared to other _4.2_ ROMs?

I wasn't complaining about battery life on 4.2 ROMs, just noting that ONLY AOIP has this issue that I saw.

All other 4.2 ROMs used less than half the percent per hour as AOIP.

Telling me to just buy a larger battery when I don't have the money for it is not an acceptable answer. Neither is telling me to go back to the crapload called "gingerbread", whose only advantage is battery life, at the drawback of making everything else run like crap.

Guess I shouldn't have bothered, since it seems the developers may be able to code, but sure could learn a thing or two about listening to others with valid issues they should be addressing in their code.
[Samsung Galaxy Exhibit 4G] teerout:
sorry dude, i think your the one refusing to see. you seem to understand your way around, you sure your not doing something goofy on the install ?
[Samsung Galaxy Exhibit 4G] detdett:
maybe you can code in a "battery fix" and share it with all of us.
[Samsung Galaxy Exhibit 4G] meekrawb:
Just use a different ROM. Jesus Christ!
[Samsung Galaxy Exhibit 4G] dwolfman:
It didn't matter what I installed or didn't install. Once I got the phone at work with AOIP on it, it ate the battery three times faster than any other 4.2 ROM. One time, to rule out anything I was setting or loading, I loaded AOIP, gapps, then put in my account info and disabled auto updates with nothing else changed. It still did it.

As QA software tester, I know how to identify software issues and bugs. The only explanation for what I have happening is there is something going on with AOIP itself to cause this. Like I've already demonstrated other 4.2 ROMs only use the battery a little faster than RootBox 4.1 (RB about 0.6%/hr vs slimbean 4.2 using 1.1 to 1.5 %/hr) with that screenshot in my OP. AOIP uses about 2.5 %/hr at home but over 10%/hr at work.

In any case, it's quite apparent now that this little group of ostriches with their heads still stuck in the sand isn't interested in hearing the truth, so consider this a closed thread.
[Samsung Galaxy Exhibit 4G] meekrawb:
You are the only one having this problem and it is our fault. Have a nice day!

Interesting. Anyone know how to tell if the same thing could be why the battery life is so bad on 4.2 ROMs with the exhibit?

We use the same sources as the SGW, besides some blobs, so yes that applies to the exhibit as well.

[Samsung Galaxy Exhibit 4G] tazmaniondvl:
Det, that's good for you. I do not have great battery life and mine is brand new. And I hardly use this phone now anyways, other then getting on here to play with other ROMs. I an not one to complain, but stop trolling this thread. You all made your point. Obviously if ARCO found a problem, then the problem exists. So please stop trolling this thread.
[Samsung Galaxy Exhibit 4G] detdett:
Taz, I thought you got a new phone?
[Samsung Galaxy Exhibit 4G] jfbs:
My battery life is fine, too. After reverting the commit for my build, it's better.
[Samsung Galaxy Exhibit 4G] dwolfman:
Looks like I have a revision 3 LCD then.

Was that code change he made done after all the 4.1-based ROMs came out?
[Samsung Galaxy Exhibit 4G] darkynk:
With the 8/3 build out, is there a battery life difference from older builds?
[Samsung Galaxy Exhibit 4G] dwolfman:
I just got done installing and setting it up on my phone. Haven't had a chance to test the battery usage yet, it's been plugged in for over three hours doing all my backups, then the installs. :)

But just from playing with it so far, I'm liking a lot of how well it does work on my phone. In fact, so long as the battery life doesn't get worse than before, I think I could live with it since the pluses now outweigh the big minus of the crappy battery life. :good: :D

I'll just have to try to remember to bring in my charging cable every day at work. ;)

Also, considering that the issue related to the LCD rev 3 patch just came up as a result of this thread this weekend, I doubt that any of the devs have had a chance to look at what was involved in that patch in time to do something about it for this new build.
[Samsung Galaxy Exhibit 4G] jfbs:
It was made sometime during 4.1 to enable vsync, but not initially.

---------- Post added at 01:15 AM ---------- Previous post was at 01:05 AM ----------

Not certain about 8/3, but I got around 36 hours after reverting commit. However, occasional white screen issue exists.
[Samsung Galaxy Exhibit 4G] dwolfman:
Battery life on 8/3 build is the same so far, unfortunately.

Guess I need to set up my own build environment. I'd rather live with an occasional white screen than never getting more than 20 or so hours out of it.
[Samsung Galaxy Exhibit 4G] jfbs:
I'll push a kernel with better battery performance this evening.

Edit: This stock kernel is for devices with LCD's that have revision 3.

Source at https://github.com/jfbs/samsung-kernel-msm7x30/tree/cm-10.1-battery

Source is compiled from cm-10.1 4.2.2, so no guarantee that it'll work with other ROMs, but it should.

Flashable zip at http://d-h.st/z9F then make nandroid back-up, wipe cache and dalvik-cache before install.
[Samsung Galaxy Exhibit 4G] dwolfman:
Will this have the overclocking options like the 8/3 AOIP build has built in?
[Samsung Galaxy Exhibit 4G] jfbs:
No oc.
[Samsung Galaxy Exhibit 4G] dwolfman:
Well, I really would rather have some different governors that normally come only in oc kernels. Like smartsssv2. Does this one just have the stock governors?
[Samsung Galaxy Exhibit 4G] jfbs:
Yes, they're stock governors.
[Samsung Galaxy Exhibit 4G] dwolfman:
Well, it's worth a try just to see what the battery life is like. :)
[Samsung Galaxy Exhibit 4G] jfbs:
When I get the white screen bug turning on the screen, turning it off and back on resolves the issue rather than waiting.

Again, why don't you try it yourself? Like the previous version, I said it worked fine for me but you said it's really slow and it lags. The only way to test it out is to run it on your own device.

I ran the 3.4.57 kernel for a few hours yesterday, but my battery was already low, so it wasn't enough time to tell anything useful. I have a full charge this morning and I'll see how it goes during the day. I'm testing with WiFi, BT, and GPS off, and Google location reporting off. I'm running the updated T679UVLK2 baseband, and I have good cell reception. LCD is rev.3 of course. I get the screen glitch about 30% of the time, but I can live with that for better battery life. I can't tell any difference performance wise between this kernel and stock. I'll post battery results at the end of the day.

Oh yeah, I'm running the 6/3 build of AOIP 1.0.
[Samsung Galaxy Exhibit 4G] spiked_mistborn:
Ok, it looks like the 3.4.57 kernel makes a big difference in battery life. I'm getting slightly over 1% per hour. I would usually be at around 40% after 10 hours.

Have you seen any other glitches other than the white screen after unlock?

[Samsung Galaxy Exhibit 4G] spiked_mistborn:
I haven't had any other issues, and so far the screen has came on when I've received calls... It might make it kind of hard to answer a call if the screen doesn't come on though. Also no caller-id if the screen doesn't come on and you get a call.

I just did a test and called myself and the screen didn't come on. I had to hit the power button two times to get it to come on. The good news is that this doesn't hang up on a call, it only mutes the ringer :) The digitizer is also active even if the screen doesn't come on, so if you do the answer gesture it still answers the call.
[Samsung Galaxy Exhibit 4G] spiked_mistborn:
I decided to see how long the charge would last with light usage, so basically no Netflix, Youtube, or games -- just occasional web browsing, phone calls, texts, email, Twitter, etc., and here is the result. This is the same charge from Tuesday morning when I unplugged it. I would say AOIP gets good battery life with the right kernel.
