Battery life wifi issue

Good day,
I just got my Infinity yesterday, and as a previous owner of the Transformer Prime, I know the kind of battery life to expect.I am getting around 5 hours of battery, half of what I got on the prime (both with no keyboard).
The strange thing is that the battery usage gives wifi 50-70% of usage. The screen is usually usually around 20%. Does any one else have this issue?
I am updated to the latest firmware: 9.4.5.22

I never owned any Prime but I have the same issue as you. Do everyone else have 50% wifi usage and about 5 hours battery or would it be a problem on some specific models ?

This is only a problem with statistics display on Android, not WiFi draining 50% of the battery. You can understand it as "WiFi mostly on" or something just try other battery widgets with their own stats, you can see my best apps thread.

I noticed the same thing. I was expecting the screen to be the major consumer, just like on my GNex, but was shocked when the Wifi was taking up so much. Yesterday I was downloading a ton, so I can see how it was then.Today not nearly as much wifi usage, and it still is taking 84% of my battery. Down to 89% after nearly 4 hours. Only 23 minutes of screen on time.

Turn off auto-sync and see how the battery life is after a day of it just sitting there.

Well my mistake. The battery life started at 94% (forgot I reset the device) on that clock. After another 1.5 hours, it dropped 2% the way it was to 87%. Just turned off auto-sync and gps. We'll see how it does now.
As far as I'm concerned, it appears to be much better than my GNex. And I have a 41WH battery pack/USB charger for when I travel. I should be great with battery life.

My WiFi % on battery is way high too, but I'm not seeing a ton of battery drain. I'm at 92% after 3 hours with 10 mins of screen on time and auto sync on. WiFi is at 88% and screen at like 7%. Kind of odd but not noticing anything totally broken yet.

Same here
I was shocked at how fast the battery runs down on my Infinity. I've used mine for about an hour and a half so far today and it's at 65% already. Wifi shows as using 50% of the battery and I haven't really done any wireless work with it - mainly watching local videos. I'm getting about 4-5 hours of battery life every day.
Before anyone suggests that it's just a bad tablet - this is my second one. Both have behaved exactly the same way. I have installed Startup Manager and used it to disable all the live wallpapers, etc...from starting up when the device boots and it hasn't made any significant difference.
What's going on...?

location via wifi is the culprit
I also had this issue after I bought the tablet. The battery was drained even in sleep mode which was a clear sign something was not right.
There seems to be a bug with google maps that makes maps ask location way more often than necassary even when no settings for this are yet made..
I noticed this when turning wifi off for sleep to keep battery cosumption down and maps came up the biggest battery hog after this change.
The remedy is to first enable location settings in google maps (you have to do this first to get access to location settings) and then disable all location updates you don't need. I actually turned everything off from maps but I left wifi location enabled in system settings so I can still refresh location manually in apps that need it so for example apps like star chart can get my wifi location instead of gps in my apartment. In fixed location wifi is accurate enough and much faster than waiting for gps signal. So anyway now i can leave the tablet sleep for a day and it will only consume 1-2% at most even when wifi is on.. hope this helps.

Wifi battery drain

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.

[Q] Battery Troubleshooting/Feedback

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.

Evita Battery Life w/ Data Connection

So I've been tinkering with my phone for about 5 months now, searching forum after forum in hopes of getting some decent battery life out of my Evita. The best I'm ever able to get having mobile data and WiFi on throughout the day is about 9 hours. That's with light to moderate use (an hour of streaming music, 2-3 hours of screen time, only mail and calendar sync for Google, 0-20% screen brightness, no games, and being around WiFi for about 70% of the time). That benchmark was reached with CM 10.2, boosted kernel, sweep to wake enabled, and GPS on for about 1.5 hours. I can get about 16 hours if I disable all sync, underclock the kernel, disable all internet connections except when I use them (about 2 hours of the 16 on a normal day of checking email, reading news, syncing accounts and such. No heavy stuff such as streaming video etc.), and disabled GPS. However, I figure what's the point of having a smartphone with data connectivity if being connected means I can't even make it through a very light use work day? I've had my phone replaced once by AT&T because 8 hours was the best life I could get on stock period. That was with data and WiFi off (about 3 hours with internet on). I considered buying an external battery case to get a more normal battery life but can't justify dropping $100 bucks when that's what I paid for the phone with a contract in the first place.
Anyway, is this battery life normal? And if not, is there anything I can do to increase my battery life and maintain mobile data connectivity/WiFi? I would also love to be able to keep my GPS on as it's frustrating to wait 5 minutes for my GPS to find my location so I can find my way around. Whenever I need to use my maps. Anyway, it doesn't seem like this is a normal smartphone experience I'm having but I could be entirely wrong.
Thanks in advance.

The battery life you're experiencing looks fairly normal to me for the usage you describe. Sync kills battery, mobile data kills battery, GPS kills battery. All in all, HTC did put an underpowered battery in this device, which certainly doesn't help but there are steps you can take to combat this problem.
You say you want to leave the GPS on because you don't like waiting for it to connect, but if you do that the thing is going to try to connect constantly, even when indoors, which will drain your battery massively. My GPS connects in seconds, try using an app called Faster GPS.
Leaving mobile data switched on has the same result, why not switch it off when it isn't in use? You can use a quick settings tile to easily switch on and off as required and it will save a heap of battery.
Think about it like this, you don't leave the car running when it's in your garage, you don't leave all your lights on when you're not home, you don't keep the clothes dryer going when there are no clothes in it. Why? Because it's a waste to have all those things operating when not actually in use.
Use an app called Greenify to hibernate apps when they're not in use, you'd be surprised at how often apps run in the background when you're not even using them.
These are just some practices you can adopt to get better life our of your battery. I think people have pretty unrealistic expectations of how long a smartphone battery should last, considering all the things we ask to get out of them at the same time.

Hey Timaa, always appreciate your input. I'll try working in those ideas and see what battery life I get. Also, I believe I found a fix. I installed the 4.4.2 version of beanstalk and enabled the conservative governor and I'm pulling between 15 and 20 hours with Wi-Fi, mobile data, and GPS all enabled all day. The 13 hour cycle is on the moderate use side (2-3 hours of audio streaming, 4-5 hours of screen time, a couple games, internet browsing, Google Now enabled) and I have the pocket wake feature on. But an average day for me gets about 17 hours. More than enough to get me through my day. I've never even approached this kind of battery life with this device and I must say, I'm blown away! My battery now easily performs my old iPhone 4 which is really saying something. Couldn't be happier.

Battery Life Expectations

I know battery life has been discussed extensively here: http://forum.xda-developers.com/showthread.php?t=2758709&page=71. But I'm just wondering if I have unrealistic expectations for the battery. I've noticed it drains very slowly when the screen is off, but once the screen is on it falls quickly. I always leave wifi on, connected to wifi for most of the day, I have gmail syncing on, screen brightness baseline is set at 50%, mobile data disabled all day, connection was to lte all day. I attached all my screenshots with some of the apps that are running, seems like ram usage is high but I'm not sure if it is normal. I know more of the running apps should be disabled because they probably aren't necessary. But I'm wondering if there are any suggestions to increase battery life? I was hoping for around 3:30-4 hours of screen on time.

You might want to get rid of the carrier IQ processes. This invasive crapware was eating 25% of my battery. Once I followed the steps in the General forum my drain is as I expect it to be. Only been two days since I deleted CIQ and looking much better now.:good:
