Hello,
I'm a first time poster looking for a little help. I've had my Verizon SIII for about a week now and almost everything about the phone I have loved with the exception of the battery life. Given the 2100mah battery I was expecting much more. I tend to be a fairly light user throughout the day at work, I have the screen brightness turned down, all data is off, and I really only am using it for texting, maybe a little bit of gaming. I have found that if I unplug at about 8am by about 6 or 7pm the battery will be nearly completely drained.
Noticing that this seemed to be a fairly common problem I started doing some research to determine the source of this. First, by looking at the battery stats I observed the same problem that many others observe, a heavy drain in standby mode.

So going off of this I started trying to determine the cause of this drain in standby mode. I should also mention that at times the phone does seem to get warm in the bottom left region of the back of the phone. I had read one tutorial explaining about wakelocks so I decided to check that out. I downloaded GSam Battery and CPU Spy to see if something was preventing my phone from entering standby mode properly. However my phone was entering deep sleep as shown below, so this confused me a bit. But clearly there is some issue visible in the standby mode of my phone, sometimes the battery will drain ridiculously fast (as high as 1% every 5 - 10 minutes). And keep in mind that this is while virtually everything, data included, is disabled. So that eliminates the possibility of it simply having to search for a signal in a weak area.

Basically I'm having a tough time getting to the root cause of this problem. I feel like there's some little software issue in there that is draining it. But I've been pretty smart about the apps that I've downloaded, I've stuck with only very common and popular ones. So would anybody have any clue to how I could identify and address the source of my battery drain?
Thanks

You don't have to thank me there is a button for that
Download and try Watchdog Lite. It's a really good monitor for finding out which apps are acting up.
This doesn't exactly answer your question, but can help with your problem. There are programs that can help to drastically improve battery life by turning off data (3g\4g) while the screen is off. This can double your battery life or more, especially for lite/moderate users. Most of these programs work by turning on the data 1 minute out of every 15 the screen is off. That way you still get email, and notifications. You still get txt and phone real time, as they do not rely on data. When you turn the screen on data is turned on, when you actually would want to use it. Especially in 4g areas this really saves battery, as 4g is a battery hog.
Battery Defender is my favorite. I feel like I should be paid for this advertisement...
Do you have BATTERY SAVER option ENABLED in settings? That makes a huge difference for me.
It sounds like you are still stock, but I used the Root66 image and after that started having huge battery drain. I did a factory reset to no avail, so then moved to Synergy Rom. Since then, I've had outstanding battery life! not sure if you were thinking about going this route, but it has worked for me. Synergy is debloated so I assumed Verizon crap to be the culprit.
The images I saw were all at 100% battery. Those are not very helpful. A shot of your battery stats at the end of the day would be a lot more useful.
Please note that Cell Standby reports incorrectly at the moment on the S3. Unless you do the fix linked above, it will nearly always be at the top, but it does not actually drain that much battery, it is simply a reporting issue.
Hi. I'm having a problem. The wifi is draining my battery. My battery will only last about 4 hours of screen on time.
I've already check the power option of disabling wifi when the screen is off. Wifi drains at least 40%of the charge.
I've read other forums but nobody has an answer just yet. I really like this tablet, but it makes me mad just having 4 hours of battery.
Driver problem, an app misbehaving, hardware problem?
What can I do? What should I do? How many of you are having this issue?

Depending on your usage, it is indeed possible to drain battery 3-4 hours. I myself never had that situation but for those who played highly CPU/GPU intensive game along with WIFI had that issue. I usually had 5-6 hours on my routine use which to me seems was not much.
So couple things I believe you should look into.
1. How is your monitor brightness?
2. What applications are you running? e.g. are you downloading on background with playing some game foreground?
Those sort of basic things. To identify whether the WIFI is actual issue or not, one thing you can do is simply turn off the WIFI and do whatever you need for couple hours and see where you at in your battery. If you have 50% drained in couple hours without WIFI on, clearly WIFI is not the issue but if you suddenly get only 20% battery drain from WIFI off, it is indeed the WIFI.
If WIFI is indeed the issue and perhaps you can try Juice Defender but it will only save battery if you are not using WIFI all the time.
For detail, please refer to http://forum.xda-developers.com/showthread.php?t=1805636.
One last thing is obvious, but battery save mode rather than balance mode gave me extra couple hours without sacrifice in my foreground application performance; however, I did notice main screen page swiping or application launch animation weren't as smooth. Almost felt like back to my old Galaxy 10.1 tablet on Honeycomb.
There is actually a bug that makes your battery overview show the percentage of wifi on time as percentage of wifi battery consumption:
-> wifi on 80% of time > shows 80% of power consumption from wifi.
How long do you have your device ?
When i first got it I also thought that the battery time was bad but now ( i have had it for about a week) i get battery drain of 10% / hr while surfing and 14-18 %/hr while streaming video over wifi and 0,5-1% / hr while standby with wifi and sync on.
I have the brightness on manual contorl and when i watch video i change the performance to eco setting.
Hi, thank you for your responses..... This is an update of what is going on.
I am already on firmware. 26, but had the problems since fw. 22
Yesterday I did a factory reset to rule out some mysterious app. The battery issue continued under wifi.
Wifi was still draining between 40 and 50% of the battery. Completely drained in about 4 hours of browsing time in balanced mode and about 40% screen brightness.
I just did another test. I played 2 movies with the wifi off. After 4 hours of screen on time the battery fell to 66%. So the tablet have enough battery juice for 12 back to back movies. That's great, I can rule out the battery.
So far I can confirm that the battery is draining extremely fast with wifi and is not a big showing erroneous battery drain.
4 hours of browsing tine is a joke for a tablet...
Any other things you think I can try?
For how long have you had it? No matter what people say, the calibration algorithms for these kinds of batteries still need several cycles of charging and discharging before they can actually read out any battery level accurately. I easily go for far longer than that on my device -- not that that fact helps you out, I know -- but I thought battery life was worse in he beginning as well. I guess it just needs to settle down a bit. Give it a week.
EIDT: Oh, and....eeehmmmmm.... do not believe the standard Android battery tool. Get yer mitts on BetterBatteryStats and get a few cycles on it, check the readouts and then report back in.

Thanks. I've already installed better battery stats.. While Web browsing battery drains up to 30%/h. I know is too soon to get to a conclusion. I will keep you post it.
Hope there is some firmware update that will fix this. This is Asus 5th tablet (transformer, prime, slider, tf300) I don't want a beta product!
Sorry about the whining, I know that you guys are helping me..
Battery life is really bad on this we need the motley kernel and some custom rooms soon !!!
I am running this tablet on performance and it is still very slow ccompared to my prime I hoped I can wait for the custom rooms and kernels before I sell this tablet i know i am very impatient
i have a tf700 too and have the same problem on wifi I love this tablet, i think we need to find a fix. Hope to hear from some of the smart people on this forum.
The reason for the low battery is this; Asus did not put a larger battery in Infinity compared to Prime.
Both devices have the exact same battery, but since Infinity runs at a higher clock speed and has a higher resolution screen, it drains the battery much much faster.
You can't really fix this with software. You can however lower the voltage with a custom kernel, making slightly improvement....but that'll also make the device unstable.
Just to let you guys know, i have assigned a fixed ip address for my Tf700 and the wifi drain seems to have decreased. I won't rely on the native android battery monitor (mine still says 85% battery drain by wifi). But i have noticed much less actually drain/hour when using wifi with a fixed ip address than not. YMMV.
I am currently using a Galaxy S3 SCH-I535, stock, unrooted, and have noticed decreased battery performance over-time. I have already viewed many similar threads to try and pinpoint particular issues (wakelocks, troublesome apps, etc.). I was hoping for some perspective whether my battery life is up to snuff.
I have seen many describe their phone life with ~3+ hours of screen time with moderate usage. I use my phone intermittently throughout the work day to chat (Text messages, Hangouts), check e-mail, and browse the internet. I do not use Wi-fi, aside from when I am home in the morning or at night, and make sure to turn it off if not connected to a network. I have sync turned on, but the only accounts I have syncing are Google Now and Gmail. I have location services/GPS/Bluetooth turned off, and run in Power Saving mode with brightness at ~50% and haptic feedback turned on. My reception is subpar, usually about 2 bars and spotty 4g connections at work. I do not stream music, play games, or watch videos during typical use. No facebook, weather apps, etc. that can be culprits some times. At best, with the usage habits described, it is typical that I get 2 hours screen time over a single day (~16 hrs) before I get in the single digit battery %.
I've attached some screen shots I took of battery stats at ~50% drained (I didn't get a screen grab for it but at that battery % I had probably 1:05 to 1:15 hours of screen time). I just started using Wakelock Detector to find any problem apps - after tweaking some apps last week this has been pretty typical behavior. I have even swapped batteries with my wife's S3 to see if it was a battery problem, but did not notice a difference.
Any feedback would be greatly appreciated. Are my expectations for battery life too high? Is this typical, or am I running lower than I should be?
That is pretty good but this comment is by someone who is rooted with a custom ROM and custom kernel since I bought the phone 7 months ago. I can't really say that is the average battery life for the device.
This looks pretty normal to me. You said you had spotty 4g coverage, while your phone is coming in and out of 4g service you'll get decreased battery life. Same happens with your mobile data and Wifi signals if they aren't strong connections.
It looks like your phone is running pretty well. People getting 3+ hours of battery life are either using their phone all the time and hit that threshold in something like 8 hours, have amazing coverage, and/or have no syncing services turned on. A key to run away Wakelocks are having a high battery usage that is coming from something other than your screen, such as media and android system. Other Wakelocks you can't do too much about. There's a thread that is titled the noobs guide to Wakelocks that gives you a pretty good direction trying to isolate Wakelocks and finding fixes for them.
I routinely get about 2-3 hours of battery life in a good coverage area in 16 hours, if I'm in a spotty area my battery will drop much faster. At a friends house with worse coverage I'll be lucky to hit 2 hours. I pretty much use my phone the same way as you.

I recently purchased a refurb transformer t700t
The main problem i have with this tablet is that battery life is really low with wifi on - only about 5 hours with a full charge.
If i turn off wifi the battery life doubles, for example when watching a movie it averages about 10% battery loss per hour.
Checking battery usage with wifi on shows about 40-50% wifi usage as the maximum battery drain.
I've read posts here and elsewhere on the issue, didnt see any solution. Is there a solution?
Also, i ordered another unit (brand new) and the same problem is there. Hope to return the new one and replace the refurb one..
Would be really grateful if someone can help me with this. My basic requirements are 10 inch full hd android tablet under $200
Reslly need your help guys, i use this because i cant use a laptop.... (Problem in my wrists)...
There is no real "solution" for this because there are so many possible causes...
It's probably not the wifi itself that causes the drain, but apps that keep waking the tablet from deep sleep and are using wifi to phone home.
Any social media app like Facebook, Google+, Google location, Twitter etc are high on the list of possible culprits.
To diagnose what it is that's draining the battery you can try apps like Gsam Battery Monitor, BetterBattery Stats or Wakelock detector.
Al of these have a learning curve to interpret the stats they provide. Gsam is probably the easiest to use...
Check if the drain is the same if you disconnect the tablet from the dock before putting it to sleep. Some TF700 have a mysterious battery drain which seems to be related to the dock.
You could also try resetting your router, putting it on a different channel (WiFi Analyzer may be helpful here).
Greenify is another great app you can try to hibernate offending apps. This is probably your best option if you don't want to spend hours and days trying to find the apps responsible. Especially if you do not have root on your device and cannot uninstall cr*** like FB....
Good luck
Thanks for your reply
Its not an issue of excessive wifi, or even wifi when the tablet is off. My problem is that wifi uses around 50% of energy when the tablet is on.
To put this into perspective, when watching a full HD movie with wifi off the tablet uses around 10% battery per hour.
If i switch wifi on and do light surfing it uses about 20% battery per hour.
Ive updated firmware, cold rebooted and disabled preinstalled junk - this is only when using just a web browser.
This is in balanced mode, brightness minimum
Does every tf700t experience this problem or is it just a few units?
Anyone here who had atf700t with good battery life on Wi-Fi
What is the typical battery life with wifi on?
In 2 hours and ten minutes with screen at mimimun, balanced mode, ive reached 50% battery
Anyone else experiencing this? Atrocious battery life post upgrade. Nothing odd running in background, program or processes. Rebooted phone. Started the day at 100% with moderate usage at best, I'm already down to 19%.
Battery life is relatively unchanged in mine after the mm update. Easily make it through the entire day with 50-60% battery life remaining. I disabled a whole bunch of the bloatware (and will be removing it entirely when I decide to root my phone) and battery life is wonderful.

Mine has been fine, slightly better with doze/disabling packages. Do a back up through Smart Switch and try a factory reset. I do that every time I update.
I'm envious of your successes. I'll give it a bit to see if it stabilizes, if not I'll use SS and reset/restore.

I will recommend "Package Disabler Pro" to disable bloatware. Costs but is worth the cash.
Mine went through on Thursday and so far battery appears ok.
I have noticed however the lighting is messed up all over. Play books night light feature is broken and dims it to unrecognizable levels. I have to go into the settings again when in the book and disable auto lighting and manually raise it. When back at the list of books screen, the brightness drops to nearly off again.
Also it seems the notifications when listening to music are much louder. I could listen to mp3s via poweramp while reading a book and get an SMS text and itd be a light little sound. this is playing louder than my music and very annoying.
My batter life was horrible after the upgrade. Here's what I did to fix it.
1) Wifi sleep policy - Changed that to "While Charging" (big difference noticed after that)
2) Fully charged phone then let it run down to 0 (must let it power itself off)
3) Wifi Scanning has been moved under Location setting. Go to Location -> Improve accuracy, make sure Wi-Fi scanning is off.
Batter life is awesome now.

1: Apps/sync will use mobile data as priority if this is done while waiting to connect to wifi. In turn, using even more battery if an app/sync wakes the phone switching between networks.
2: This is damaging to Li batteries. To extend the life of your battery, it is better to keep it topped above 80% and cool(not very common in real world applications). These aren't Ni batteries, long gone are the days of "memory discharging".
If you don't need notifications at night, use airplane mode. I miss Xposed, Autotasker, and Amplify(formerly Bounce)... Greenify is a good alt atm
Note: Sometimes even Play service updates will introduce bugs and or "retarded" policies that will destroy the battery, especially the "Now" systems. It can happen at the most random times as well and not at all most. Every now and then the fat man will get stuck in the tube.
All thoughtful replies. I don't have Location on ever, unless I'm using Waze, so that's a non-issue for me. Allowing WiFi to sleep when the phone is off, while I'm only connecting via WiFi, effectively makes my smartphone a dumb phone, until I wake it up, right? The fact that I need to start changing around "normal" settings on my phone, to lesser benefiting ones, to get back to the battery life I had before I installed MM is pretty silly. I've been hoping things would settle down, but they don't. I can try using SmartSwitch later to see if that helps.

No, it will connect LTE and then switch to wifi. LTE use more battery life, the network switch uses a bit, then finally you are into wifi. If your phone wakelocks or alarms(location ping, play service ping, etc) it will use more battery than wifi always on. Personally, I've tested both to make sure a wifi wakelock bug hasn't been introduced as I do with every update and play service update(it does happen and it's horrible drain). I see more savings always on.
If you meant you disable mobile network, yes, dumb phone, text and call. Also, I disable mobile usually always as I piggyback off work cell at work, and always wifi at home. I only toggle mobile data when necessary.

I believe this is what most people encounter. Most dont have unlimited data and use WIFI always. I think by default, WIFI is set to always on, even when phone screen is off. WIFI will rape your battery. I did my own tests with wifi vs 4g and just by using my 4g all the time, battery quadrupled. Many argued that WIFI uses less battery, and i have the best of the best wifi router/modem/isp with 5ghz ac excellent coverage. Not the case for me. I have unlimited and just stick with that now. Battery life on MM has been great for me.
My battery life is 4x better. I couldn't be happier.

Not that I know of.
Though they JUST released Marshmallow. Verizon is probably still patting themselves on the back even though they released several months late. What I'm waiting for is a miraculous root.
I never use my phone the same amount every day, so it's hard to say exactly what kind of battery life I get, but I have noticed that it has improved. I would usually be near 15% by 10pm after coming off charger at 6am. Now I float around 25% at 10pm. So it seems to be better, even if only slightly so.
I see a minimal improvement, but I was doing what I could without root prior to sleep unnecessary crap.
Weird, when thye MM updated happened, up until the last two days, I was getting much better battery life under MM. But the past few days my battery life has declined dramatically to the point that I am not getting through a day of minimal use. Screen only 2%, Android OS consuming 76%.
I just fiddled with settings (Changed Wifi sleep to While Charging; Turned off wifi scanning). I am going to also try a reboot to see if that helps. I swear it started just about the time I started looking at Nexus 6p replacements).
Update, rebooting, and removing a few more useless apps and battery life has returned.
