Battery I dunno, some people seem to conclude the batterylife is bad within an hour after flashing For me, just about all roms are pretty similar in battery, getting me through 1 day with ease, and not getting through a 2nd day Thats fine with me really since I charge at night.
Available RAM is indeed pretty low in 2.3.3; starting off at about 115 but quickly dropping to 70ish when actually doing stuff. And this is with a pretty conservative amount of installed apps. *misses cm7 for available ram*

I prefer 2.2.1 task manager as got option to clean level 1 or 2. Thats gone lol any one else notice barcode scanner

Eg22 battery life

Could be me but it seem like the battery drains faster with this rom Is anyone else noticing this?
Sent from my SPH-D700 using XDA Premium App

I'd say it's similar to the other gingerbread leaks. Nothing as great as SRF 1.2 for battery life yet that I have come across.

Froyo had source to optimize, but you still should get good battery, you did calibrate right?
Sent from my SPH-D700

you could also be playing with it more

10 hours since flashing and at 49% now. (Started at 100%) Pretty good if you ask me.

I am getting random reboots and force closes. This sucks. Don't know what's wrong.
Sent from my SPH-D700 using XDA Premium App

Srf was good for me too, but the best battery life I have seen is with marcusant's i3 rom. Haven't tried the new leak yet. Probably wait til acs does their thing with it.

Did you restore data? I have used it all day and have not had one force close. Try to Odin again and if you restored data do it without restoring data.

RE: force closes, usually it means you restored apps or data that need to be reinstalled. If an app FCs, uninstall and reinstall it.
RE: battery life.
You can't make a judgement until you run a calibrate cycle and go through at least one charge cycle. Usually the first battery cycle on a new rom seems like really battery life, then things improve quickly. Since the rom has only been leaked for about 18 hours now I don't think anyone can give a useful opinion on battery life.

I just flashed from midnight 5.3 and everything is running a-ok here. Try wiping the unneeded files from your sd card and delete the default android files before reinserting your sd card into a newly flashed eg22 rom.

I flashed it at around 10am this morning, and with some pretty good, but not heavy use, I made it to about 6pm. When flashing this morning, I was around 92%. So yes, battery life is pretty good. Nothing will beat SRF, but now that I've tasted the gingerbread, I'm not sure I can go back to Froyo.
*Edit* Since being off the charger for 4 hours, and surfing the internet on both 3g and 4g, chatting on gtalk, multiple text messages, I'm at 76%. I'm impressed.

Charging my phone

Whenever I leave my phone charged overnight, I wake up to around 70% charged. It's as though once it reaches 100%, it stops "charging" and it starts using the battery's energy, rather than the AC. Any help?

What kernel/rom are you running. The only suspect is that your kernel does not have "trickle charge" in the new kgb kernel you have to enable this with the app.

Yeah its pretty simple man, find droidstyle's guide for roms and mine for kernels. That'll give you the info you need.

Is there any Custom ROM in particular that you would recommend?

go here http://forum.xda-developers.com/showthread.php?t=1238070 and follow step 2, then go to http://forum.xda-developers.com/showthread.php?t=1459905 readthrough the first part on TW kernels, choose one of the 3 custom kernels (not the stock one), best advice is to read the op of each one and find one you think will work for you. they are all three well written kernels. one is already oc'd to 1200, which means no need for voltage control if you plan to oc your phone. most phones are stable at 1200 but thats just from doing alot of messing around and odining. the second post is the instructions for flashing the kernel. the first post just explains all of them to the best i could w/o kanging any information from the op. i just ran what i knew off memory. links to each kernel's op are at the bottom of post 1. i did links to the op's instead of posting dropbox files due to the fact that I want people to make sure they know what features each kernel has before they download it.

I would give battery calibrator app a try. It could be that when you flashed your ROM, the battery stats got jacked up

The way I understand it is WIPING BATTERY STATS Is pointless, battery calibration however is recommended. Heard this on many tech podcasts.

They are essentially the same thing. Battery Calibration is wiping the battery stats and running the phone dead than fully recharging.
I have been having a very similar issue. A buddy of mine (captivate) and I found that the phone wont charge past 98% on CyanogenMod with the Glitch kernel. I set the phone to not lock and keep the screen on while charging and the problem went away. The phone also would not stay on A/C power after reaching 98%. This issue was fixed too.
I think its an inherent problem with the batteries on the phones, since the issue occurs on many different roms/kernels/phones.

whether it's caused by the phone, ROM, or kennel, battery calibrator is a simple app that is at least worth a try in my opinion

Ouch ... bump charge it and wipe battery stats in recovery. Or maybe even do a fresh install. Sometimes that will fix it

Stop spreading that freaking lie. Wiping the battery stats doesn't do anything. Besides it is wiped every time the phone is charged to 100%. Don't believe me. Look it up, a Google engineer has posted this along time ago.

Darn.. really? Then CWM should take this out in the features
Sent from my GT-S5830 using xda premium

WIping battery stats is useful when installing a new ROM, so it can measure battery capacity better (extreme tl;dr version). Install BetterBatteryStats and look for unusual wakelocks and processes. Report back with what causes the issue and we will see. If you could include screenshots of BBS, that would be the best

You don't get it do you? It is wiped when you install a ROM. It is WIPED when you charge to 100%. The batterystats.bin has no effect what so ever on your wake locks, battery problems, or anything else you think it is related to. All it does is report to the settings what has been using the battery.

You know there are nicer ways to tell someone that wiping battery stats doesn't do anything . If it doesn't do anything than it shouldn't be in the options...period. I was trying to be helpful and offer a suggestion..and it couldn't hurt to try.
.. so whats your suggestion so no more "lies" get spread??

CWM is largely generic, so the Battery Wipe option is there whatever device. It is a waste of Dev. time to remove/customise for every device.
It doesn't do anything... in this case. It may on other devices.
But this is largely OT now... so back in the room.

It doesnt do anything for any device. A long time ago it was thought to do something. But a Google Engineer said otherwise pubically.

Check that android.process.media is not running and consuming 20% of CPU cycles. This process always runs when you restart the phone as it scans the phone's internal and external SD card for media files.

Seems like all the threads i read that mention this problem the user is running Omega rom 2.x.. Maybe its something the dev as added into the rom that is causing it to kill your battery..

It's one of the older updates i guess so the battery life should ideally be an issue and a lot worse than 4.1.1.

I would. You might get lower battery life for a while, but this has the SDS fix in it as far as I know, and I'd MUCH rather be protected from my device turning into a paperweight than just running low on juice...
And sure, I could use a custom ROM, but I happen to like the stock ones. Serves all my needs perfectly.

Some guys attribute the increased battery use to the media scanner which runs randomly and drains the battery life
Also i believe that the screen brightness at max setting had been increased to like 300% of what it was in 4.1.1

The 4.1.1 ROM's have a critical bug that can cause your device to randomly just die, for no apparent reason, and it's not fixable once it happens. You'd have to return it to Samsung. This is the SDS bug, Sudden Death Syndrome.
The 4.1.2 ROM's have a fix for this, as do pretty much all the custom ROM's as well.
Personally, I'd much rather have reduced battery life and relief from the worry that my device could just randomly die.

Can you please post the modem version to this update.
