So I notice that an hour on wifi surfing the web took about 20% or more of thE battery...even playing game doesn't do that to the battery. Anyone experiencing similar thing? Anyone with 3g, is data looking the battery too?
Just keeping wifi turned on is also drains the battery for me.
Check your screen luminosity.it is the biggest battery killer
I'm running the Moto234_eVo_Carbon_V0.3 build and I've noticed that even with the screen off and the phone idle my battery drains at a pretty good rate when compared to WinMo. Any fixes for this?
for me 3g/h draw much power than wifi, almost 1.5x-2x of the wifi surfing..
Screen brightness is easily the biggest batter drain keep brightness as low as possible,
Data connection will hog more than WiFi if you are in an area of weak signal and your device is constantly searching for a signal, when your at home or work using WiFi just turn data off and switch to only 2g networks, set setcpu to screen off 245 245

Screen brightness definitely hits it hard, then wifi and bluetooth, keep em off whenever you are not using them and of course apps running in the background, grab a task killer, if its not needed, it shouldnt be running or else it will use power.

Get "current widget" from the market to see how much powers are being used. While screen off, my phone only drain about 4~7 mA...
I just came across this. Super detailed analysis of battery usage.

3g draws much more power than wifi. If wifi is available use it over 3g. But like others have said, the screen is by far the biggest battery hog.

I don't see how the screen is the biggest energy hog. When I leave my phone uncharged untouched over night and it it displays 7mah on current widget, I lose 40% battery in 7 hours.

That's unusual...i lose less than 10% over night...even with bad reception in my room, that didn't kill my battery. Maybe you can try this to test it out. Fully charge before you go to sleep. The next morning, check your battery in setting to see what is using the majority of the battery drain during that period...this might help you find the reason...
If noting else is running, Cell standby will eat the majority of the battery power.

Yes thats true, exactly the same in my HD2: 3-7mA = 1% an hour or less
Wow, I installed Mdeejay_eVo_Sense_v_2.3Revolution to see if this build helped on battery life. I charged my phone over night and had a full battery at 11AM (according to the meter) but by 7:30PM, my phone was completely dead. During this time, I had two 5 minute phone conversations and used GPS for 9 minutes. Other than that, the screen was not active and I didn't have WiFi enabled. Is this typical? Doesn't make running Android very practical on the HD2. This is only the second build I've tried but it's not looking very promising.

Something is wrong with your build. Try his newer build. They got a new kernel. If that were my habits, my battery would drop by only about 25%. You should install "current widget" from the market. It help you keep track of battery usage. On standby, most people and I got about 3~7mA. If you get a higher mA, that mean something is eating your battery.
Please give Mdj's New Build "Froyo Sense Revolution 1.6" that comes with his new kernel which is suppose to make battery last longer. Hope this helps.

i hope this enlightens you and yes wifi kills battery but it is not the biggest battery killer and wifi is more harmful to your battery life if it is not connected which means it is constantly searching for a network which sucks the life out of your battery.
I think the wifi modules on the new kernels (Hastarin > 8 & MDJ) are consuming too much power.
I usually got 5 ~ 8 mA in sleeping mode with my wifi turning on on the previous kernels, but now I got 8~60 mA and the battery status is showing that wifi is taking about 30% of the battery. Maybe this is because the 802.1n is enabled by default!
I am posting for a friend that has a SNS. The couple of days he has been draining the battery in about 6 hrs. I looked at the battery usage and it said that the display was at 60% and the graph shows a constant fail of power. I checked and he has the screen set to auto brightness and the screen times out at one minute. The only other thing that I cna think of is that he has poor cell coverage but we are using wifi in that location which his phone is connected to. I understand that poor cell coverage causes power drains but with the major of his data going through the wifi one would think that the cell power drain would be minuscule. Thanks in advance.
It depends on how weak. Data is not going to route over the cellular network, but it will try to maintain a connection for things like calls. Thus the phone will attempt to maintain a connection to the tower unless airplane mode is enabled or the cellular radio is otherwise disabled.
If the signal is really weak then the gain is going to be automatically adjusted to try to boost the signal - this is going to cause an increase in power used, sometimes substantially. If you spend most of the day in this situation then you don't have many options currently if you want to receive calls on the phone (you could look at a SIP solution).
If you don't care about receiving calls just turn on airplane mode and then toggle wifi on.

You need to provide screen on time and awake time. If he just got the phone and is using it a lot.... well then six hours is not bad for an android phone.

Not really. Maybe 6 hours continuous use, something like 3 hours display at 20-50% and 3 hours talk time; that would be normal. But 6 hours low-medium use points out that something is indeed wrong.

60% display means the phone was on and actively used for over 3 hours. That's a fair bit but isn't too much really, but it depends on what else is running durng that time. As mentioned, awake time is also important because it means the phone is actively working at something even though the screen is off. He may have a rogue app that he installed sucking power. Or simply leaving the web browser on a webpage with a regular refresh cycle will cause the browser to continue to run in the background keeping the phone awake while the screen is off. I've gotten in the habit of going back to the google home page when I'm done browsing to make sure it's on a "dead" page.
Anywho, more details are needed to figure it out. Just saying it's only using 60% display isn't enough to find out why the phone only lasts 6 hours. Mine lasts between 24-48 hours depending on usage from heavy to moderate. With light usage I figure the battery would last 3-4 days, but I'm not that light of a user and I generally top up every night anyway as it's better to top up a Li-Ion battery than let it run down all the time.

Huh???
When it says "What's been using the battery" and it says "Display........ 60%"
that just means that the display is responsible of 60% of the battery drain that has occurred since last boot.
For example, if you were at 100%, then turned your phone on for 5 minutes and scrolled back and forth on homescreens, lets say your batter went down to 95%. Well, if 2.5% of that 5% loss is from display, and 2.5% is from Android System, then when you check the battery screen it's going to say "What's been using the batter?"....... Display - 50%; Android system - 50%.
If you did the same thing for 4 hours, and the battery drained down to 20%, you might still see...... Display 50%, Android system - 50%.
In other words, the % has nothing to do with how long the phone has been on.
also if screen on time is 3 to 4 hours, yes the battery will be very low by then.
Thank you all for the advice. As I said this is my friends phone. i don't see him using it a lot we are both programmers so we use a computer for most everything, and we have both our phones on wifi because of the terrible cell signal. I will ask him to try and keep up with everything he does to see his use patterns to see how much he is really using the phone. I will post later on what apps are running and his amount of use. The main reason I am not sure is because this has just started happening with in the last week. We have been in the same location for 6 months and it has just now become a problem.

Hmm...ok that kinda helps, but it doesn't really explain what's happening when it uses that setting. I know that PRL means preferred roaming list, and GSM Auto means it selects automatically, but how it selects and why it uses less battery is what I want to know.
Reading through threads I see lots of people saying JD and similar apps are good and lots saying they are bad. This is quite confusing for someone who just wants to get good battery life. In my experience I have gone from finding it good to finding it bad. I will try and explain why this occurs so that people are able to decide if it will be worthwhile for them.
First install Battery Monitor Widget and find out what sort of drain your battery is experiencing every hour.
With a stock rooted G2 with data connection on continually (no wifi) I was getting around 80-150 mA which explains why it would not last longer that about 16 hours. Most of this drain seems to occur from data connections. After installing JD or something similar the drain can be reduced to around 50 mA. Which is great, suddenly you get the claimed 1.5 to 2x battery life. JD seems great.
But after you install a good ROM and custom kernal, remove or freeze all the apps that keep using your data connection unnecessarily and install Better Battery stats you observe that JD stops the phone going into a proper deep sleep. If you dump it the drain on the phone drops to very low numbers usually under 20mA sometimes 5mA or even 2mA. This means you use around 1-3% of the battery life of the phone overnight with no changes. Now your phone can last days between charges. Note this is with Data or Wifi connections turned on and Sync active always.
Summary:
On a badly set up phone JD improves battery life (for the lazy)
On a well set up phone JD worsens battery life (takes some time)
Note: I got the best results using Speedmods kernal but I have no reason to think that other kernals could not get similarly low battery drains.
Thanks for sharing your observations. I have juice defender and have had similar findings. The wake locks jd causes play into the aos bug of the phone which is why it can make things worse on a well set up phone (the extra drain from the wake locks outweighs the savings from turning the data connection off when it's not in use). If not for the aos bug it would probably be good in all cases. I had noticed this in my testing and am glad to see I'm not the only one.

Thanks for sharing your observations.
If I had seen your post much earlier than I wouldn't have to buy JD. Anyway, I have gone through the hard way, and learnt how to keep my phone organized and minimized rouge apps issue. JD is pretty much useless now.
IMHO, I think Battery monitor widget pro seems to be a much better buy
Thanx for this helpful info!
BTW, kernel not kernal
I do not have a lot of widgets and sync as little as possible. Mail sync is only on demand (when I have time to read it), and Weather is every 6 hour (disabled in night time).
So my battery live is good ½% standby and with normal use it can easily last a full day (no gaming, just Internet, Talk, SMS).
I decided to try JD in order to save even more juice, but JD ended up using more battery than it saved me!
So I can confirm that JD is good for the "lazy user" and bad if your aware of your sync. and how your apps behave.
What do u mean by dumping? You said if you dump it and the drain goea away? Im a bit confused

By 'dump' I just meant uninstall JD. If you uninstall JD your phone will be able to deep sleep properly provided it is set up well and you actually save more battery.

Sure you can do that, but it's not necessary. I leave wifi and 3g on and still have drain of 5mA all night. I wake up and have lost almost no battery. The same applies for when the phone is idle during the day.

Many people report that battery drain after upgrade their Nexus S to android 4.0.4. So the main reason for that is our android 4.0.4 leaves wifi on even when the phone is sleep.
How to fix: Go to Settings -> Wi-Fi -> Advanced -> Keep Wi-Fi on during sleep -> change it to "only when plugged in" or "never"
And now, my phone's battery can last more than two days
I have found that keeping the WiFi on always actually improves my battery life. This is especially true when there is a weak signal (like in the basement of my house).
With WiFi always on, I get minimal drain (maybe 20% for the entire day) with the standard battery. Without that, I was able to maybe 16 hours before the battery was entirely dead.
How is this any different than just turning Wi-Fi off if you aren't in range?

If there is wifi network available you should ALWAYS connect to it as opposed to cellular data. Does not matter whether screen is on or off. If you got wifi available use it at all times.

I find wifi drains significantly more battery than when on the 3G data connection.

I agree, having wifi off would end up using cellular data, a very quick and fast drain on the battery. If you have wifi most of the time then this shouldn't be disabled, I found that having wifi on all the time actually helps improve battery life since my phone doesn't hog onto the cellular data network. I am around wireless most of the day & night, so I end up using more of WIFI.
This particularly makes sense during the nights, when the phone is hooked onto wifi instead of cellular data.

Or use battery saver apps, like GreenPower, which you can set to only sync your email and/or apps once every 15 mins./30 mins./1 hr./etc. You can also set it to "Night mode" and schedule it to automatically turn off WiFi and Data connections during a certain period (I set mines at 12am to 7am, so I won't be bothered during sleep with any email and/or app notifications... and also save my NS' battery).
i was at 55% at about 5pm yesterday after 10+ hours of battery usage, 1.5hrs of screen, and probably 2 hours of LTE (the rest wifi). i use juice defender so when the screen is off it generally cuts data signals for me. well from 5pm to 9pm my battery went from 55% to 1% with maybe less than 30 minutes of usage (all on LTE though). i looked and no unwanted programs were running in the background.
i charged it overnight, got up and after an hour this morning of ALL standby (seriously the screen was on 3m), i went from 100% to 87%. that would mean on 100% standby the phone would have died within 8 hours, which is definitely not right or even similar to previous battery usage for me.
i restarted my phone, recharged, and so far it has been on for 40 minutes and the battery is at 99% with 2m of screen time, which makes a lot more sense. so have you ever experienced something like this where an android OS restart helps your battery, or does it sound like i might have a bad battery?

I seem to get it when I am in a poor LTE coverage area, which includes one of my offices. It is strange. "Cell Standby" will usually have the largest battery usage in your settings. My temporary fix is to turn off "mobile data" from the toggle in notifications, especially if you have wifi where you are. You can usually tell when the battery is being drained b/c your phone will stay warm even with no apps running and the screen off. The only other thing that seems to help is restarting it every day or so. When I don't have this problem, the battery life on this phone is amazing, so I don't think it's a bad battery. If you find out a better solution, please let me know!
I'm assuming you get off work at 5 and use the phone more. If so, turn off juice defender when you leave work. Since juice defender turns off your signal, you have to reconnect every time you use the phone. That kills battery more than anything

Doesnt that defeat the purpose of having JD? Has anyone shown than JD uses more battery than not having it at all?
Fyi cell standby doesnt actually use as much battery as it reports, its just incorrectly displayed on the battery meter. Hopefully there will be an update to fix it eventually. Google it if you want to fix it manually.

Cell standby is just a reporting bug. It is not actually draining your phone as much as it shows.
There are two separate problems. There is the problem on the international S3's where it is reporting cell standby incorrectly. There is another problem with some of the ATT S3's where they are continually connecting or re-connecting to the network where they have a poor LTE signal. This is actually using the battery. You can feel the heat from your phone when you have no apps open and it is normally cool to the touch. The only solution I have found so far is to turn off mobile data, and the phone will cool down again and stop draining battery.

Yeah I agree I think this is exactly the problem. I've only seen it once in a while though

I disabled some of my ATT apps yesterday. I'm hoping that may have something to do with this issue, but I am in a location with a better signal today, so I don't know yet if that helped.

Right. It's just cosmetic.
I don't have LTE in my area and my battery life is okay. I use wifi at my house and at work. I just think it could be better, but i am used to my dinc with my custom rom and kernel. Amazing battery life. I can't wait until we get some sweet roms and kernels for the S3. So far i am super impressed with the phone.

i think you guys are right. the only thing that fixed my problem was restarting, which obviously also turned off/on the mobile data. how would you do that normally? just hit airplane mode and then turn it back on?
do you guys think this is a bug with AT&T that will be fixed?

Turn it off in the notification drop down.

This isn't a problem that too many people are having, but there are enough that it must be a bug, at least for ATT. There is a toggle in your notifications that will turn off mobile data. I don't think it is enough to just turn it off and back on. If you are in an area with bad reception, you have to leave it off or the draining continues. If you find something else that works, please share with us.

Just to confirm, a reboot fixed it. I was running my phone for over 10 days straight before it happened so as long as it only happens every 2 weeks or so it doesn't matter

I'm also seeing this issue; battery gets hot and drains quick in sleep.
I'm running stock, and only rooted.
I do notice when checking my battery that "Android System" is taking up the majority of my battery, by a considerable amount. Is anyone else who is experiencing the drain issue also seeing this under their battery reporting menu?
