what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
In 2 hours, I have lost 29% battery life. I'm pretty sure this can't be normal, especially with 1+hours of Deep Sleep.

If you were to post this over at the BBS thread, they would tell you a few things right off the bat:
1. the facebook app is a battery killer. I'd start by freezing it (if you need facebook functionality there are more battery friendly apps for it)
2. Looks like you are doing a lot of syncing. turn it all off.
3. Enable root features in bbs since you're rooted (lets you get more info that may become relevant).
4. You need more idle time. plug in and unplug your phone to create an unplugged reference, then leave it be for a few hours.
The AudioOut_2 wakelock is an interesting one, especially since it's high on your list. In my case it showed up when I tried poweramp and it seemed to be related to the auto-start-when-headphones-plugged-in option, so if you use poweramp check that option. Others seem to get it from viber. If you have that, remove or freeze it.
So, give the above a try, and check a new dump. This will probably give you more stuff to look into. If you find a problematic app you can then determine whether it can be fixed by changing its settings, greenified, disabling its autostarts, or if you just need to avoid it.

From what I see you have had no, or only one bar of signal? If so, you may want to use Airplane Mode. You can use Airplane mode and still use Wi-Fi.
Have you been around Wi-Fi? If you aren't around Wi-Fi, turn it off.
NFC. Is it on? Do you use it? If not.. Turn off.
If your battery level shows inconsistency, you might want to calibrate your battery.
I hope i helped, im not quite sure why you loose 11% every hour, while mostly in deep sleep. Go to performance control and use some tweaks for your kernel.

The low signal shouldn't have any affect on the battery of the G, when I was on aosp I used houcha's kernel an I got great battery life around 23 hours with 5 hours of screen on and was at 22%, with set CPU profiles engaged and no kernel tweaks from any app. And I live in an area that primarily has 0-2 bars of service at home and full lte when I work I leave everything on, all radios and data sync. Now that being said for some reason the development is moving towards synergies kernel, and it doesn't have nearly the battery life that houcha's gets

The AudioOut_2 wakelock can be caused by corrupted Mp3 files on your SD card. It was wreaking havoc in our SGS4G community and the fix for us was always to use MP3val to scan and fix those files. It cleared the AudioOut_2 wakelock right up. I know these are totally different phones but hey its worth a shot. http://mp3val.sourceforge.net

Low signal does in fact drain your battery. When you have zero to one or two bars, your phone is searching for signal, It causes the phone to increase power to the antenna, to get signal.

I understand the premise that low signal causes mor power to be drained, my point was that it doesn't cause 29% on this phone that's not even close to possible

Ever since I got my SGS3 last year, I noticed that WiFi would drain battery rather than save battery. For whatever reason I always got better battery life with WiFi off rather than on.
I noticed a lot more wake locks too. I don't know if it was because with a solid WiFi conneciton, apps tend to refresh a lot more than they normally do.
Enter the HTC One. I have noticed the same type of effects. I've only had it for 2 days but I am noticing better battery life without it.
So I want to collect some data using a poll. Do you get better battery life with it on or off?

It goes inactive, but it doesn't actually get 'turned off'. If I don't have it turned off, what happens is when my wifi goes to sleep then mobile data goes back on. I don't want that.
of course you get better battery with Wifi turned off. but doesn't Wifi consume less battery than cellular data? my balance is to keep Wifi on ANYTIME i'm in a trusted wireless network and manually toggle off cellular data when I'm using Wifi.
It burns battery when it isn't connected and on but I get better battery with it on and connected

Hi there,
My friend has an S3, and we are baffled to the problem.
Basically the phone has 3-4 hrs battery life from a full charge. We tried a hard reset, new battery, app killers, disabling apps, virus scans, adware scans, etc. No avail. It just eats battery on or off.
The phone does run very hot, just sitting there the temperature is up around 50°c. The SD card also won't register.
Has the handset developed a fault?

I think that normal battery stat if you always connect 3g internet. Try to use 2g when screen off using tasker profile, monitor wake lock then disable it, disable location service and enable power saving mode. It should reduce power consumption.

Well I had an S3 before I got a Note 3. I've set his phone up exactly as I have both of these set up. I could go a day or 2 on the S3 without needing a charge, if I wasn't using it.
Even on the note, I'm always in a 4G signal, and always have apps running in the background, and diddle on my phone for a fair bit during the day.... I still easily have over 50% battery come home time.
His S3, even left with data network deactivated, and not using the phone at all, will be flat within 6hrs.
Time for a new battery , if thats won't help . paint it blue and throw it to deep waters . Good Luck .

Not sure if it is that,but with stock ROMs I feel kind of a battery drain,while with aosp it's amazing. Google services updated right when I went back to stock,though. So,not sure.
Use trickster mod to force the phone to go in a deep sleep and handle the wake locks
Check this..
1. Use LTE Only When Needed
Never use LTE if you're not using it at all and select 3G instead. 4G/LTE features high-speed mobile data connection but eats a lot on the battery more than you think than 3G.
2. Selective Features
Features are amazing and may actually help you every day but not all of them are good for the battery. Keep those features you use at all times and turn off others which are not needed on every day activities.
3. Wireless Connectivity
Aside from mobile data, watch out for other wireless radios such as Wi-Fi, Bluetooth and NFC which consumes power and you must turn them off whenever not in use.
4. Preferred Internet Connection
Whenever there is an available and decent Internet connection via Wi-Fi, use it instead of mobile data to preserve power on your phone.
5. Display Screen
Around 50 per cent of power consumption is allocated on the screen which means you need to manually set the brightness level comfortable to you, minimise screen timeout and use static yet dark wallpapers to save energy on the display.
6. Location Services
GPS can kill your battery life and set only certain apps allowed to use location services - those which requires it.
7. Apps and Widgets
Widgets are good display designs on the home screen but only a few helps your battery. Remove widgets you're not using anymore and uninstall the app altogether. In addition, be careful with certain apps which are poorly written that may eat away battery faster or damage system files on the worst part.
8. Don't Forget This!
Samsung installed a non-removable Power Saver on your Galaxy S3 and you should use it as much as needed. Whenever you are not using any Internet connection or high tasking services, activate the Power Saver from the notifications shade to manage battery life better.
9. Colour Profile
Galaxy S3 features screen mode and you should use customise the profile to help save power consumption on the Super AMOLED display screen.
10. Refresh Regularly
It is recommended to restart your phone once a day to refresh the entire system after an entire day of full work just like a computer. It will also help the memory to perform better after a reboot.
11. Factory Reset
In worst case scenario of apps damaging the system, you'll need to reset the smartphone. It will restore the default apps and remove all other culprits which may have caused the battery last shorter and poor performance on the phone.
12. Drain the Battery
Certain times require battery drain similar with laptops and notebooks to enabling healthy charging cycle. Usually, battery draining a device once a month then getting a full charge for about four hours keep cycles healthy than those units without recharging cycle.
13. Avoid High Temperature
Avoid leaving the phone inside your car or putting it on a surface with direct sunlight to prevent damaging its battery. High temperature will damage the battery pack leading to poor performance. However, extreme cold can also affect the device leading to moisture damage.
14. Root Access
Rooting will void the warranty but if it's already gone, why not do it anyway. Root access will enable you to control various aspect on the battery and processor to improve power management.
15. Custom ROMs
Samsung Galaxy S apps and TouchWiz UI consume high amount of battery which makes other Galaxy S3 users to resort on custom ROMs. Custom ROMs always feature better power management, CPU tweaking and larger memory compared to stock ROM and if you want longer battery life, get a custom ROM.
having battery drain issue, cell standby and over-counted are the main reasons showing in battery stats. how can i get rid of that? after full charge it takes 4 to 5 hours to plug in the charger again.
What are you showing us here? Looks to me like a mostly idle run over about 12 hours, getting roughly 2% per hour drain. That's a little higher than I usually see, but not horrible depending on conditions, especially if the small amount of use you did have was demanding. How much screen on time are you getting out of a full battery run?
I would suggest getting the app betterbatterystats (search xda) to get a better idea of what your issue is, if you actually have one...
Thanks for the reply. I was trying to say that why stand by time consuming that much percentage? Is that normal while data and wifi disabled? And what is that over-counted thing? As you said stand by time is little higher than normal and depends on condition. What kind of condition you're talking about?

I've never run with both data and Wi-Fi turned off (I use data for notifications when idle) so that might be higher than expected idle drain. I typically see 1 - 2% per hour drain in that configuration.
In my experience, you'll need to better narrow down the cause of the drain if you want to fix it. It may be due to weak cell signal (though your screen shot shows what appears to be decent signal), or possibly an app that frequently wakes in the background looking for a network connection. If that is the case, having data and Wi-Fi off may actually hurt your battery performance.
Get the BetterBatteryStats app, it will help you narrow down the cause.
