Is there battery saving by enabling wifi sleep policy when screen is off? Seems to me it should but I would think ROMs such as Unnamed and SHOstock would have it set that way by default if it was..

This actually belongs under the Q & A section...
However to answer your questions... Setting it to never when plugged in is a good idea. it'll make it so your WiFi only suspends and turns off the radio when the screen is off and running off the battery.
Our device's wifi standby power drain is so low and wifi uses so much less power to transfer data in the background than the cell radio that leaving wifi always on saves battery.
This isn't 2009 when wifi chips hogged power just by being turned on - the BCM4330 has been found in many phones since early-mid 2011. (The BCM4329 eats a lot more power.)
Now in the case of UCKK6 firmwares, the wifi chip seems to be running broken firmware that causes it to wake up the CPU all the time - but that's just UCKK6. On a non-broken firmware like UCKH7, XWKL1, or XWLA4, leaving the wifi chip always on will consume insignificant power when not connected to wifi, and save power when connected.

Interesting, have many UCKK6 users suffering battery drain problems noticed a big difference in battery life after flashing
UCKH7, XWKL1, or XWLA4?
I'd most certainly give it a try if others had success going this route..

If you're suffering any battery drain that involves high Android OS battery percentages (70%+) when wifi is on - Any of those three firmwares should entail significant improvement.

yes, I was going that way but hellraised ROMs don't seem to work with passwords which I need for my work. I actually believe there is something wrong with the phone itself and not the firmware.

Hello,
I've had my GS II for about a week, and the battery life has been pretty stellar, except for days where I work at the office. For some reason, there, the battery drains at about 2x the rate than in other areas. A very similar thing happened with my Captivate, but the battery lasts longer with the GS II.
However, today, at around 1PM, my phone started heating up so that it was hot to the touch, and the battery drained 60% in about 1.5 hours. Something went terribly wrong. And even plugged in, it was draining faster than it could charge!
How can I find out what happened? I don't want this to happen again.
The only thing I did was listen to a podcast with BeyondPod, but I do that every day at work over lunch. So, nothing new in my utilization.
Any ideas appreciated!
Thanks,
Jon

I had a similar experience today. I was talking on the phone when the top of the phone got really hot. Like it hurt my ear to hold the phone against it. And then the phone rebooted. Since then it's been running phone. Need to figure out what caused it though. Might be a similar issue. But my battery life has been pretty good though. Can easily make it through a day with moderate to heavy use.
I am running CM 7.1. Not sure if that had anything to do with it. But even if it did, there is no way I am going back to stock.

Unfortunately, AOS often falsely reports high. Sometimes high AOS usage is fine, sometimes it's not.
I've gotten some of my best battery life with AOS at 60%.
Can't tell what happened to you without some statistics.

Yeah, this sounds very similar to what happened to me, but with stock ROM.
Two follow-on questions:
1. If it's ROM-independent, then could it be something in the hardware that's short-circuiting? Like... the cellular chipset, or perhaps the modem firmware?
2. Can you explain what about CM 7.1 is so superior to the stock rom, which I'm finding pretty fantastic at the moment?
Thanks,

Sh1t happens. That's the way it was with multiple Windows Mobile phones I had in the past and it is obviously the way it is with multiple Android phones I have now. Usually a quick reboot of the phone will resolve the problem. As long as it didn't happen again persisitently, you are fine.
The cause is somewhere some app or service was stuck in a bad place that uses a lot of CPU or data or both. This will cause phone heats up and battery darin faster. Unless you have full dev environment and logging on the phone, it is virtually impossible to track it down.

Yeah, but does this kind of thing happen to iPhones and WinPho phones? Just curious. I am trying to convince friends & family that with the GS II, Android has finally reached parity with iOS. Perhaps not quite yet... ??
i never had battery drain but once in a while I do notice my phone gets hot on the back cover in between the SGS logo and the camera while I'm using it. If I put it down for a bit, it cools off. I figured it was just hot from use and I never thought anything more of it.

What make you think GS2 is any better than other Android phones in this regard? Anyone can make a mistake or two in programming and it is impossible to write bug free code.
Remember, latest Android Gingerbread OS is 2.3.7 and we are at 2.3.4. There are a lot of bug fixes (and new bugs) in each incremental release from Google alone. On top of that you have Samsung's customization code and various apps you installed.

It does happen to iPhones for sure. We switched from blackberry devices to the iPhone, at work, three months ago. We had five different devices experience similar heat and battery issues. The cause is typically from apps or services that sync with online data.

I think running incredikernel with his tweaks or the fact the tweaks aren't working with that kernel is probably causing the quick drain. You can run that kernel ,but I would delete the file with the tweaks on it. I am not sure of the name it was in this thread some posts back. Otherwise, switch to the kernel that came with the rom and try that.
Running 1.6.5 sp1 and having good battery life. Then again, I was running the ICS version for a while. From what I remember it's better than I was getting with 1.1.
My battery has been pretty bad, but don't know if it's the ROM or its the upgraded radio. Did both at the same time. Same programs and usage patterns, but significantly shorter battery life. Even with mobile data off, the drain during sleep is a lot higher than before.

I have. Nothing out of the ordinary - all the same things I had running in 1.5.5. The problem is not wakelocks. something is making the battery drain at a higher level all the time. I also used battery monitor widget to look at the battery drain. Before it would drain at around -180ma when the phone is sleeping. Now the lowest it goes is -310ma. Similarly, when charging, it used to charge at a max of 970ma... Now it maxes out at around 790ma. So something is just constantly drawing more power, even on a brand new flash of 1.6.5 with nothing else installed.
So I think the new radio is the culprit and am hoping that the ICS upgrade comes soon with a new radio.
Same thing is happening to me exactly

You have the screen on permanently.... it is THE largest user of battery in a phone, always. And OLED screens when displaying bright and light images use masses of juice.
And your phone never sleeps.
No idea what the hell you are doing, but it isn't a video player... it's a phone.
The image tells me your Display is always on and it isnt in sleep mode.
Did you play some games and listen to music ?

Hi guys,
Thanks for your replies. Thing is, when using the phone, even when doing simple things, the battery decreases drastically faster than before. I am also using a extended battery.
Are there any other things, apart from brightness and turning off Wifi, GPS, that I can do to improve battery life?

No... if you use the phone with the screen on for 3 hours solid.
And I agree, the screen was on the majority of the time but still, the battery life is decreasing more than before
Use the app Better Battery Stats to see if your phone has any other background processes running aside from what you expect it to. Uninstall/disable the offending apps then try to do your thing again.
Keep in mind as well that ICS uses more battery in general vs Gingerbread though, so that's another factor.

It's getting hot and draining because of the screen on time, not the ROM.
The screen uses the same power irrespective of the ROM. Only brightness and screen content will affect it.
Download "Watchdog Task Manager Lite" turn on the monitoring and wait and check the stats, if you have an app that is misbehaving, un-install it.
Most battery issues are due to that.
Hope it helps.
Flash modem from your region, means the version of modem that came when you bought the phone.
Example, when I'm on stock ics / cm9 it gets real hot near camera when I use edge.
Flashing my GB modem fixes that issue.
Also it's easier to flash what you have already used instead of finding the correct one.

I've tried so many stock ROMs, custom ROMs and full wipes, and I haven't gotten anywhere. My phone's battery drains around 6-10% an hour (and that's a conservative estimate) while on battery with Wi-Fi on. For comparison my Wi-Fi on my GALAXY Note 10.1 has been connected for 12 hours straight and the battery has gone down by around 2%. Thus I am convinced I do not have a network problem. I also do not believe it is a rogue app: I have of course checked BBS for wakelocks and while I do see a fair amount of wlan_rx type wakelocks there is no app behaving out of the ordinary. I have also tried turning off sync, but to no avail.
TL;DR Thus my question to you is, which ROM (if any) can prevent this Wi-Fi drain from occurring?
I think wifi drain is often more related to your kernel. Maybe you should try Siyah kernel. Or if you're running a stock rom, Speedmod kernel.

Agreed. Wifi is controlled by the kernel, every rom and kernel I've used drain the battery when connected to wifi. It's just a power hungry system. Try to reduce screen brightness whilst browsing.

I am not familiar with LG products in the slightest, but I had a yellow screen of death the other day...something I have never seen in my years with samsung android products. Anyone have any idea what this is maybe it is pointing to a hardware issue?
LG made a great phone, but I don't think I will keep it much longer. Locked boot loaders, no sources, and history of terrible updates have me regretting purchasing this phone. I tried my hand at building a working jb release when I first got the phone and it is going to take a skill set I do not have and I hate waiting on a company to do what they've never done in the past..

Easy, brother. I have only had one of my apps/utilities run higher than AndroidOS ever on this phone; however, that said, I think there is a problem with the way it's being calculated. I'm getting really good battery life with good sleep and still AndroidOS shows the highest by far. I know that's abnormal for it to be so high and still get good battery life, but it is what it is.
Edit: you've installed the fast dormancy toggle, right? As for the yellow screen, I've seen it once in my two months with the phone, just rebooted and carried on. Forgot what they said it was...but it is here in this forum somewhere.

I was just about to post something similar. Andriod OS being high kind of makes sense if nothing else is using the battery, although you would expect that number to fall significantly with increased screen on time and heavy app usage, which it doesn't ever seem to.
I've been having horrible battery drain lately. I'm currently traveling for business, and just use my OG for web surfing and stuff when I'm in my hotel. I leave the phone in airplane mode, with WiFi on. About two weeks ago, when I was on The Base 0.4 in that same configuration, my battery would drain maybe 1% an hour while I was sleeping.
Recently I've been on The Base 0.7.3, and my battery drains over 5% an hour while I'm sleeping. This means no screen on, no apps running, and even turning WiFi off! How does it use that much battery when it's not doing anything? Now, I'm not entirely sure what kernel I'm running. The first time I installed The Base 0.7.3 I used sk8's kernel. After getting poor battery life, I reflashed 0.7 and 0.7.3, this time choosing the freegee kernel. I'm not actually sure if the kernel changed though.
Anyway, I think I'll post again tomorrow with some screenshots from Better Battery Stats+ and CPU Spy.
I'm wondering if this recent botched update had the battery fixes we need. Hopefully they'll re-release it soon.

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals.

Believe you are correct. There were issues on the Samsung Infuse and even the international SGS3 for a while... it was referred to as 'memory leak.' Has been worked out by devs on XDA. You can put memory leak in the XDA search above... it's above my pay grade.
Edit: It's great to see another RD here... hope you will reconsider keeping the phone and stay !!

When I would get bad drain, which has happened several times, I could narrow it down to a couple things in order to solve the problem.
In my case it would always happen after installing Google+. Uninstall and reboot would usually fix the issue. If I got drain on a fresh install without g+ installed, I found that if I installed the 2.2 kernel separately as a stand alone zip, that would fix it. Don't know why but it may work for you too.
I don't have screen shots, but today I recharged at 38% after 3:10 of phone use and 1:55 screen on time and about 15 hours off charger. That's with Wi-Fi on the whole time and Bluetooth for about 9 hours. I have my work exchange account on active sync with push notifications. Facebook and Twitterer to 4 hour intervals.

Thanks for pointing me in the right direction. I have Google+ uninstalled, but part of me thinks Google Now may be partially the culprit (although why that would be the case with all radios off, I don't know).
I'll try a fresh install of the 2.2 kernel and see if that helps. Thanks.
I can't speak for anyone else but FDT did wonders for my battery life. I was only able to go about 12 hours prior to disabling FD.

I always install GNow, love the inverted version.

This is good for sure... it's just that compared to other phones, Android OS and Android System should not be that high.

That's what leads me to believe it's a faulty measure...

^^^ This is indeed worth considering.... I think the question then becomes why is it consistent among the 3 roms we are using? Maybe when JB source is out and something is built from source all will be good.

I would be less inclined to believe it is a faulty measure if we had a different ROM not built off stock (AOKP/CM10) that could produce different values. However, I seriously doubt anything built into either of the two custom ROM's is geared toward normalizing that reading. That's why they are both the same as the stock AndroidOS percentages. Jivy is probably right that it's a kernel issue. With the size battery we have, imagine the potential if it is a true reading (androidOS out-of-control) and we can get it under control down the road. We're talking double the current best battery life you've ever had on this phone at the very least.

Get BetterBatteryStats, select Since unplugged and Alarms to see what is waking the device (making it not go into a deep sleep). eBay was a big culprit for me.
The wakelock that keeps the phone awake during background data transfer (screen off) lasts 6 seconds (I am guessing it does it in multiples of 6s) regardless of how long the sync takes. Everytime email, facebook, gmail, drive, picasa, twitter, g+, google maps, ebay, calendar, contacts.. whatever wakes the phone to check something, it will be a minimum of 6 seconds.. This adds up over the course of the day and it is counted in the Android OS. Shut down syncs you don't absolutely want/need and this number will go down. All phones with the Snapdragon S4 Pro has it, especially the Nexus4. It seems they've done some kernel work to fix/reduce it but I havent really looked into it since I don't have that phone. I've seen complaints in the Droid DNA forum as well.

This. EBay for me too. BetterBatteryStats is your friend.
Anyone else experiencing scrolling lag or delay. Clearing cache and wiping dalvik fixes it but the issue returns after about two days.
