Battery Life - wlan_rx_wake - Better Battery Stats Images - Verizon Samsung Galaxy S III

Hi,
After using Better Battery Stats I found that while at work the open wifi for guests and employee devices is causing my phone to not sleep - specifically the wlan_rx_wake wakelock. I did run shark and analyzed with wireshark and can see that my phone is responding to/waking up for every other device on that network (my office has over 5,000 individuals in it so presumably there's pretty close to that many connecting). So today I "forgot" the open wifi network and only used mobile data. no more wlan_rx_wake.
However I only got about 20 hours of battery...not sure if thats good or not...that included a 30 min lunch break at the gym with runtastic and iheart radio running - on the gym's open wifi.
Below are some screen prints of BBS at the end of the day (I unplugged last night 3/25 at about 9pm...and I have wifi and data set to be turned off via tasker from 11pm till 6:30 am every night so my phone doesn't blink all night when it gets messages - it's right next to me) It's also running the SUPERLIGHTROM v3.
Any thoughts or comments on how to extend the battery life is welcome!

That's solid battery life on the S3 right there. Unless you have an extended battery that's about as good as you will get. I never got that type of battery life on my S3

I wondered if it was. I've considered the zero lemon battery but not sure that I want the increased size.
I've gotten better battery life before by using tasker to turn off/on wifi and mobile data every 30 min or whenever I turn on the screen.
I'm contemplating upgrading to a LG G2 or a Moto X (2014) just for the battery because there's nothing that they do that I need that the S3 doesn't already satisfy.

My battery life!

I'm having a great overall experience with the Inspire 4G w/ CM7. Just wanted to show you guys some screenshots of the battery life I'm getting so far. These shots I took after a day of heavy usage, including a few hours of net browsing, texting, and e-mails.

Hey try using juice defender or current widget to exceed your current battery life. Both control which apps that are eating up your battery. Kills the non needed ones.

i've seen all the complaints about battery life but i must say mine is more than adequate. maybe because for the first 4 days i had the phone, after charging it for 10+hrs, i ran the battery all the way to 0 (til it shutdown), recharged to full, then drained it again.
it was my old habit from my nokia days.
Yeah, to be honest, this is equal to or better than the battery life I was getting with my Captivate. I can tell you with an absolute certainty that the battery did have to "break in" for a short period, after installing CM7.
Sent from my Desire HD using XDA App
Its deff better than captivate, 99% due to the screen. I got over 5 hours screen on time in a 16 hour period the other day with my rom/kernel combo with screen brightness at about 40-50%. That's pretty damn good, way better than the captivate could ever get
On my LG Ally i was lucky to get 6-8 hours with just light use. With the Inspire on cm7 i have gotten around 20ish hours with moderate to high use.
I'm still shocked that i am able to get that much battery life. lol
I'm still breaking my Captivate records. I took my phone off the charger @ 7:00am on Wednesday the 20th. I'm now at 15%.
What roms are you guys running. Im on coredroid 5.4. I get about 20 h with moderate use. I consider it to be pretty good. But no way can I get over like 30 h. I don't like to use juice defender or setcpu. Don't feel like I should use apps that override android os. Especially GB is so will optimized and efficient.

I'm on CM7 and only wish I could get the battery you guys are talking about. I just went from 93% to 90% in a matter of minutes doing nothing on the phone. It was sitting on my desk!

Not at all. It's my personal and work cell, so I talk, text, surf, and play games what I would consider a moderate amount. I don't use a large overclock. I use the smart ass governor on Leedroid's most recent rom, and my screen brightness at 1/3.
There are days that I can put it tonthe test, but my first charge got me 35 hours with 5 hours awake time.
That's it? I got this a while ago and that's before I did some optimizations... I'm going to see what it can pull this weekend before it hits the 15% warning.
Apparently I can't add images until I get some more posts.

16 hours?!!
I just got mine 3 days ago and was considering taking it back because the battery only lasts about 5 hours before needing a charge!
I have about 1.5-2 days using it quite heavy. Bluetooth and 3g on.
I cant go a whole day without charging. its worse that im on android revolution. I havent flashed the recommemded radio as im on Bell and am afraid of bricking my device.
I also use Android revolution and couldn't last one day (from 6:30-19:00). I had my WIFI on all day.
In the office we have WIFI and I think it drains the battery very quick.
When I turn the WIFI off at the office, now have 20% left at 23:00!
Yeah, my drainage is terrible. With heavy use, I can squeeze out around 5 to 6 hours with WIFI or 3G on. I've read that some people get upto 12+ hours with heavy use!

For everyone who is going "OMG battery life sucks on the sensation" but before you go exchange phone, I will tell you that I was like that too.
Coming for the MyTouch 4G with Virtuous Unity to the Sensation 4G, I went from 24+ (of medium to heavy usage) to 5 hours (with light texting and BT, WIFI, mobile network, etc all OFF). Not realizing this before I rooted and unlocked the phone (I did it the night I got home), so I couldn't exchange it. I decided to tough it out b/c other that this it was a great phone.
Conclusion: The battery life of the Sensation DOES GET BETTER over time. I know this is counter-intuitive but it is very true with this phone. My recommendation is cycle the battery (100% to 0% to 100%, etc) a lot. In my past experience is only takes 3-5 cycles for the battery stats to do its thing but with the Sensation, it took more or less about 2 weeks to break the 12 hour mark (which is about 20-30 cycles).
Currently I get about 18+ hours (moderate to heavy usage).
Unplug at 8am when I wake up, about 6-7 hours of music/podcasts while I'm at work with light web browser (2G b/c that's all i get in the office) and light texting, wifi on 6-8 hours, BT ~30mins (in car), 2-3 hours call
on InsertCoin 4.4.8 ICS 4.0.3

[Q] What exactly IS good battery life?

So I understand battery life is dependent on several factors, but I'm looking for a general number of hours of what's considered "good" battery life for the Inspire. I have looked at a couple different threads around XDA in an attempt to tweak my battery life to the fullest, as a heavy user of text messaging and the occasional use of my data services, but they don't ever seem to give numbers. The following shows my battery life from about 8 this morning until about 4 PM:

So, I'd guess that I would roughly get about 10 hours from a full, overnight charge down to zero. This is using the CM7 Nightly posted here with radio 12.56.60.25U_26.10.04.03_M and the latest TalonACE kernel with the BFS scheduler. So, am I getting good battery life by the standards of my fellow Inspire 4G users? Keep in mind that I live in a bit of a small valley so reception is poor here until I walk up toward my university's campus. Please let me know if I forgot anything; this is not a request for help on tweaking my battery, just whether or not I should look into trying something else to improve it further or if I've hit about my max.
If you don't regularly use data, juice defender will help you alot.
But to answer your question, on average I can get about 20 hours of battery life with 2 - 3 of that being screen on time.

I do a good bit of texting as well, about 2 hours of web browsing/gaming/xda-ing, and I work in a metal shop so my phone is always searching for signal. I can make it through a 10 hour work day but have to charge as soon as I get home. While I'm sleeping it only drains about 1% per hour so if I didn't use my phone it would last much longer. I'm running rcmix3d v4.0 with killersloth script. I've personally come to the conclusion that our screens are battery hogs and there isn't much we can do about it. So yea, i'd say your drain is normal.

If you can make it from when you take it off the charger in the morning to plugging it back in at night without prohibiting your use than that's good battery life for the inspire. I think on average people get 4 min per 1% battery while screen is on. That is if you are being reasonable about brightness. I just use auto bright though and I can make it through the day no problem.
I know for me I get about 12 hours on a heavy usage day but when I use it only for messaging I would say about medium or light usage i get 24-26 hours of battery using CM7 Nightly's And this is with wifi connected 24/7

I have Rcmix Runny 3.3 on my Inspire, with the UV script. I'm a huge texter, and usually text consistently throughout the day. I unplug the phone about 7:45 am on my way to class, go through the day, occasionally connecting to wifi, and make about an hour phone call at night, and by 10 pm I've got anywhere in the 40-50% range of battery left
Seriously? How old is your battery? Also, how good is signal strength where you are? because at my house (small town in southern US), signal absolutely sucks and is switching networks constantly. I left my phone at home one day and after eight hours of screen off idle, the battery was at 68%. If I am in town at school with a three+ bar 3g signal, I can go eight hours at idle and still hav 94% left.
I get on average a battery life of 10 hours, but i'm constantly using my wifi. I do turn it off whenever i leave the house though so it's not constantly searching for a signal
I usually get at least 16 hours from a charge. 3-4 hours listening to music with bluetooth headphones. 2-3 hours screen on time. Phone calls, e-mail, occasional Pandora, etc. I am using Juice Defender ultimate, and have an Anker battery. And I'm on ARHD 6.3.1 with the recommended radio.
I feel that 10 hours is a good minimum benchmark for my phone. I have the screen brightness is set to auto and I get between 12-16 hours on a cheap 1800mAh battery with moderate use.

Battery Life All Over The Place?

Hey guys,
So its been about 3 week since I've had the SG3 and I love it, everything except the battery life.
My battery life varies alot day from day which is really weird.
I have LTE on (but i'm either at the office or home, so wifi is usually connected instead), background sync on, GPS off, Bluetooth off,NFC off, about 25% brightness and power saver mode on at all times.
Somehow it seems that when in standby and not in use it drains more battery than when in use and using LTE instead of WiFi.
For example today, full charge since 8am, and I'm at 38%..(It's only 3:30). This is being on WiFi for 90% of that time and only occasionally texting and checking twitter/facebook/email.
Your experiences?
My GS3 gets great battery life (well, at least compared to my old D2G lol...). 5 hours and 20minutes off the charger, and I'm at 65%. But mind you, my screen has been on for nearly two hours of that, and I've been on the internet/in a call for 30mins of that, and texting for the remainder. People seem to be getting mixed results as far as battery, it's just one of those quirks. There's actually already a thread going about battery life.

My battery life was pretty awesome. I can get through a whole day with no issues
But when I am at work and tethering, definitely leave it plugged in.
Just flashed beans rom v3 and my battery life took a hit.

Hmm interesting.
The screens only been on for 54 minutes of the 8 hours 11 minutes the phones been off the charger.
For some reason when I'm about and using LTE and constantly calling/txting/tweeting and what not I have better battery life than sitting at home or at the office on wifi and using the phone less.
Yeah my battery life is also very inconsistent. Just sitting at home on my desk it will sometimes drop only a few 3% over several hours and sometimes it will drop 35%. I haven't been able to figure out any contributing factors yet. I do get terrible cell reception at home but I keep it on wifi, and the above examples are when the phone is sitting in the same place.
consistantly 20 hours with 4 hours screen time on and usually with still 25-30% battery left. Always on 4G never on wifi. Never have battery saver on.
Only thing I do have is a setcpu profile for screen off that severely limits the cpu.

I have only had my S3 for 2 weeks, but I have been able to easily get a full day out of the battery. I typically have about 1 hour talk time, 2-3 hours wifi and maybe an hour of 4G web surfing.
I do have the battery saver mode on (not sure how much of a difference it makes) and I generally don't charge during the day.
Mine is also very inconsistent. When it is just in my pocket it lasts a really long time 12-18 hours, but if I'm doing something simple like listening to music with the screen off, from the sd card it dies in half that time.
When I'm home and connected to WiFi I have been turning off mobile data. Whenever I wake my phone up from sleep it notifies me at the bottom of the screen "connected to my wifi network". So I don't know if the WiFi goes off in sleep mode, if that's the case then it normally would be connecting in and out of 3g/4g hadn't I turned off mobile data.
I've also been very religious about fully closing apps instead of just hitting the home button. Also using task manager to clear out running processes and ram
Both of these seemed to help out tremendously

Phone overheating - very poor battery life

My N5, running XtraSmooth + stock Google kernel recently started heating up a lot. Now I know its summer time and naturally it would tend to get hot, but my father's N5 is always very cool to the touch. Even in an air conditioned house running a stability test brought my N5 to temps as high as 86°, whilst the other N5 was just about hitting 50°. My battery gets notably hot too, and of course that hinders my battery life too. Does anyone know what's going on?

My guess would be you have an app/process running full wack on your phone running up the CPU and draining battery. Look at battery stat screen maybe that will help. Try factory reset and run it empty for 30mins or so (no account no apps) then set up one account and app at a time.
Android malware/virii are on the rise, and I was hit with something that did this but did not show up on the battery monitor of any app.
I strongly suggest an immediate full wipe and clean flash, as well as changing your passwords if you truly want to be safe.

Hey, I tried that earlier today but to no avail, battery stats look normal, Facebook is the only third party app that uses battery, but only 2% at that too. It's only kept the phone awake for 50s, and CPU total is 2m so it doesn't look like its Facebook, but my battery still idles at 40-45°. I wiped and started again from scratch but first I let the phone set for 2 hours to let ART finish carrying out any optimisations so the phone could cool down and perform optimally. Antutus stress test still ramped my CPU all the way to 80° whilst the other N5 hit 71° this time around, it quickly went back down and cooled off quickly yet my Nexus took forever.

Mines stared to do it too I'm on stock and ElementalX. I've hit 85°C and as it's still rising turned it off. I've seen a few reports of this. I've no idea what it is but suspect an app update. I've used greenfly and Amplify to lock everything down and it seems to work. Its at 52 and charging ATM. Until I did that I couldn't use the phone and charge at the same time

I just changed ROMs altogether, even after wiping I was still getting ridiculous temperature gains, more worryingly so for my battery. I remembered during winter to keep the phone cool I added adhesive copper to the battery and CPU, I applied thermal paste and made the copper thicker, I also *removed* the copper from the battery, since during summer time it'll only make things worse. That seemed to have worked since my battery isn't anywhere near as hot anymore. The CPU still gets very hot - around 80° still, but it seems to level out much quicker than before.
