Totally believable. EF02/10 is a solid ROM with great battery life. I can hardly wait for official release!

I love galnet v5.2

But the battery drain isn't worth all the good things this rom has to offer. So sad to know I couldn't use my phone for long if this rom remained.

Ditto. I love MiUi but the battery drain makes it impossible to live with it.

Its like having the fastest and best looking car but you only to drive it for 5 mins before buying more gas. I'm thinking of buying a battery pack just to get normal usage out of this rom. Its about 30% below where I'm usually at and I haven't been doing much.

Use the official miui build from MIUIAndroid.com. I lose 1% battery an hour on that rom.

Okay ill give this a shot and see how well it works.
I am using GalnetMIUI v6 and I don't have any battery drain. With some txts, calls , bit gaming and surfing I can get about 30+ hours of battery.

I can totally confirm this. Only thing i'm missing now on MIUI is my language, but as this rom is more than perfect compared to Samsung rom i will stay with this. I've got some random reboots in 24 hours i flashed this but it's still good!

Love this rom,but the battery drain is insane.Last tried rom was hawkish prem 3 with galaxian kernel,battery lasted over 3 days moderate using.
you can try my rom iVastROM 2.0.
i post it today.
it's very fast and the battery lasts much

Eg22 battery life

Could be me but it seem like the battery drains faster with this rom Is anyone else noticing this?

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?

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.

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.

Display always 75% or higher

I don't know what happened but I'm having issues. I cannot get the display to fall below 75% and it sucks because between my EVO stock battery and my extended battery you can actually see the battery life being sucked away rapidly.

I have the same issue, it is isolated to Sense roms. It doesn't happen with AOSP, which is why those are the only roms I can use due to the battery life. We had a thread going for a while with some other people who had the same problem, but nobody could really get to the bottom of it. I reached out to Aamikam but he couldn't really help or didn't want to. I didn't know if a logcat or anything would have helped but no one really answered me. It happens on froyo and gingerbread sense roms, and I never had the issue for a long time but then I noticed it the first time on MikFroyo 4.62. I've tried everything since then but no results.
Only thing to do right now is switch to an AOSP rom, I highly recommend Team Nocturnal's Xplod. Very smooth with Tiamat 3.3.7 kernel and more eye candy than CM7. I would love to be able to use MikG again but my battery literally dies in 4 hours, regardless if I'm using the phone or not.
Alot of ppl seem to think that 75 percent or more of display is bad. Really it isn't. The battery stats need to equal 100 percent. On sense roms that's the way it is and there is nothing wrong with it. Now if your experiencing high.android system usage, that's a problem. As long as everything else is relatively low, its all good
Sent from my PC36100 using XDA App
Its after I installed the new update. Even downgraded to earlier gingerbread and still 75 plus.
Yes my system is low but I can watch my battery meter lower in realtime. Well I guess its time for a new toy.

If your actively using your phone and it drains rapidly that's pretty normal in my experience. But if its draining a lot during idle, check for a rogue running app. Otherwise not using auto brightness is a good mentioned trick along with underclocking with a new kernel should help
Sent from my PC36100 using XDA App
It has to do with the use of a generic power_profile.xml. Neither CM or stock use correct values for this.

You don't get it...this is not normal display usage. I remember what my battery usage and battery life was like before this problem came up and there was a huge difference. Before, cell standby was my highest usage and I could get 25-30 hours on a charge. Then display usage shot up to 90% give or take some, and battery life dropped to 4-8 hours. I can understand if display was slightly higher than everything else, but display is at 75-95% while everything else is under 5 or 10. There is absolutely no reason why the display usage should be that high even when the screen has been OFF the entire time. That's not normal. I have multiple screen shots to back it up.

So using bootmanager (finally works now) I loaded miui. And my display is no higher than 1%. So something is very very wrong with sense and 4.5 updates.

Battery Life on CM7 (AOSP versus Sense)

I've been running the latest nightly (20120722) for a few days now with less than stellar battery life. It seems that everytime I run an AOSP rom the main battery culprits appear to be cell and phone idle, where's with a Sense rom, it' the screen. I have a relatively new battery. I'd say moderate use, typically.
Anyone have suggestions on getting better battery life with CM7? I'm running the stock kernel at 245/800, ondemand, deadline. Also running V6 supercharger at 5.
Any advice is greatly appreciated. Thanks!
Sent from my HTC Speedy
I've gotten 12+ hours today of cm7.2 7/15 nightly and barely at 50%
Did lots of recordings and such.
Dunno
I don't use the v6 script, or do any mods at all.
Just run it as is.
Stock battery too.

Yeah I've gone back to 7/15 to see if it's any better. I seem to remember it being better; I'll report back later today. Still curious why cell standby is the main battery eater on CM7 (or AOSP ROMs in general) as compared with say, SSX or newSENSE, which was the display...

Aosp shows true signal where Sense won't. So AOSP having a cell standy over display sounds about right. Sense always thinks it has signal and AOSP has no signal thanks to sprint. In my area Sprint blows, so that's what I *think

This is better.. I went back to the previous nightly (20120715) for a few days now. Still moderate use.
I'm currently running the stock kernel at 245/1.21, ondemand, deadline. Without V6 supercharger and I didn't flash the ICS theme either.
Perhaps the 20120722 nightly did not play well with my device.

If V6 SuperCharger is not setup correctly, or the setting is to high. Your Battery life can take a hit.
