[Q] Battery life on standby (NOT in airplane mode)

I seems like we have a discrepancy in how much battery life a TF uses in standby. Some folks seem to be burning <1%/hour, others >3%/hour. Obviously, this makes a huge difference in the total time a TF can be expected to last on a charge.
Please indicate how much yours burns per hour. Please ONLY answer if you run your TF as follows:
1. NOT in airplane mode
2. With wifi in the default (run in background) configuration

What setting is to run wifi in the background?
Also, would the number of apps (singned in) and thinks like exchange emails factor into this?

Yep, a lot of things could impact this. But, the dichotomy seems so clear-cut (literally, <1%/hour for some people vs. >3%/hour for others) that I don't think those things by themselves can account for the difference.

I understand and agree. There should be some type of baseline. can you explain what Wifi setting you mentioned above? I have 3 options - Sleep when screen is off, Never when plugged in and Never - I know thats not exactly how they read but its something like that.

The default is to "Never" disconnect...

Dunno how many %/hour, but I've gotten from 14 hours to 17 hours.
Picked up the transformer once in a while, put it down, etc..
Here's a screenshot of the 14hr one, charged it at the end for a few minutes.

So you don't think the amount of data being communicated per application affects battery use in idle?
What do you think about signal strength from the WAP? (being further from the WiFi router, in another room, many walls and objects between the unit and the WAP)

I'm comparing my results to what I'm seeing on the Xoom, which is pretty much identically configured to my TF (same email accounts, same apps installed and running, used with the same routers, etc.). The Xoom uses well under 1%/hour on standby, the TF right around 3.5%/hour.

I'very configured my TF to turn WiFi off when sleeping.
Yesterday my TF was unplugged and unused for a full 24 hours for an 8% battery drain.

The reason there will be discrepencies between peoples devices is because everyone installs different apps. It's these apps that drain the battery more/less, so install a battery monitoring app and check the logs every few days. If you're losing more than 1% on standby per hour, then get a task killer program and tasker, and set up schedules to turn off apps at times you dont need them. Also make sure you have actually set the battery app up properly, by changing the rating it thinks the battery is (to 6600mA) instead of any default value it has.

If you are using Battery Monitor Widget then it's from settings>monitoring preferences>battery capacity. Default was 1200mA on mine originally. If you're using some other app, I've no idea.

As an update, I decided to go ahead and do a factory restore, just for kicks. I'm not experiencing much closer standby performance to my Xoom, about 1%/hour or maybe a bit less. In four hours since the restore, I've lost 5% battery life, and that includes a bit of use.
It's possible that the battery just hasn't calibrated since the restore, and so I'll report back if things return to what they were before. At this point, though, I'm hopeful that something was corrupted or misconfigured, and that a factory restore did indeed resolve the issue.

Coolthanks for the info will have to check out that app. Right now i am using battery indicator pro whicb does not have a option to change battery capacity

Another update after the factory reset: charged the TF to 100% and unplugged at midnight. At 8:00am this morning it was at 78%, so roughly 2.75%/hour discharge rate. At 10:00am (also only on standby) it was at 74%, so 2.6%/hour total for the 10 hours.
The Xoom was at 48% at 8:00am (forgot to note its battery life at midnight), and at 10:00am (also on standby) was at 47%. So, the Xoom on standby is burning .5%/hour, which has been my general experience with it.
Both the Xoom and the TF are configured with the same email accounts and settings, the same general configuration (wifi, etc.), and the same apps except for the Asus apps. Since my experience on standby was roughly the same with the original (non-updated) TF build, I don't think it's the Asus apps that are causing the burn.
If most others were experiencing the same thing, I'd write this off as a purely academic exercise. 2.5%/hour burn rate on standby isn't terrible, particularly since I tend to charge every night anyways. My concern, though, is that if others are getting <1%/hour with the same basic settings, and as I'm getting on the Xoom for sure, then the question becomes: is there something wrong with my TF specifically?

Well my transformer is doing better than that. I lost only 3 over 5 hours. Overnight from 10 to 10 battery went from 33 to 27 percent so looking at 0.6 % per hour. Btw I have wifi set to turn off with screen off. Why do I need wifi going if I can't see the screen. For mail when would wake the device it checks the accounts immediately. So........

I've had my TF with me most of the day letting friends play around with it so it's had what I would consider "normal" use.
Starting at 100% this morning when I left and now has 65% after ~8 hours. (See attached screenshot)

I am battery anal too but anyone else feel like discussing a 2% drain difference in idle is kind of ridiculous.. no one runs exactly the same stuff on their devices of course it will be different... to be honest if you are concered about battery drain during idle.. you obviously leave your device unused alot... in which case battery life doesn't matter a great deal cuz you aren't using it hahhha

Disagree with you. I think standby life is very important because the tablet is something you wanna pickup and have immediate access to for information a nd media without always Worrying if the battery's has enough juice. My nook color can go several days on stby and 3 to 4 days of casual use with standby. This tab doing same stuff is giving me 36 hours tops.
Cm7 on nook color has sleep issues and so doesn't enter deep sleep and so battery drain is about 2% instead of. 2% per hour on stock nook.
maybe our devices aren't sleeping deeply and draining much faster.
Something a Dev. can check?

Wifi issue?

Ok I think I found an issue with my infinity and need some confirmation. Here is the test. Charge tablet to full. I remove from charger and spend 10-15 minutes browsing the Web. Now check battery usage. Is Wifi your number on power drain? Here is what mine looks like.

For comparison I used my xoom tablet for 10-15 minutes doing similar activities and my wifi power usage was around 2%.
Also just an FYI I'm not in a strange wifi environment that creates any issues. I'm about 6 feet from my wifi hub and I noticed this usage today after work where wifi was between 50-60% of my total usage and that was on my work wifi.
Anyway I'd be really interested to hear if anyone is seeing a similar issue. I also created a ticket with Asus asking about this issue.

I hope you know that the stock battery stats are very unreliable. Under a better battery stats app, I've found that wifi isn't quite as consuming as apps, so I think the system stats are incorrect

Your is what I'd expect. In fact you got 91% after two hours. That is better than my xoom. This explains why some people claim good performance and battery life. Mine will be below 90% in like 30 minutes usage.
I think there is a wifi issue and this might be a way of identifying bad tablets. I'll see what the ASUS support people say and post it here. The bad news is this looks like a hardware issue...
Before I completely get excited can you make sure your wifi is always on. Go to settings, wifi, advanced, make sure keep wifi on during sleep is always.

The screenshot is also missing the "ASUS Customzied setting" menu option on the left, right under Apps. Looks like either custom ROM or not an ASUS tablet perhaps.
For what it is worth, I have noticed the same issue with my Wifi eating up tons of battery. I haven't done any tests, but it certainly feels like my battery is draining pretty quickly with Wifi on. It is certainly draining much faster than my TF101....I would expect that to be the case to some extent because of the processor and screen upgrade, but not this much. There is another thread going on TranformerForums about the same issue. Someone reported that leaving their device fully charged with Wifi turned on overnight had drained it down to 19% by morning, with no use.
Not sure yet if this is a real issue, but it seems strange that Wifi would use significantly more battery than Screen.

Don't rely on the battery usage screen. It's not like it's got an ammeter coupled to every battery drain. It just calculates percentages based on the information it got, it's all guesswork and needs lot of calibration to be correct. The reason WiFi is blamed as the major drain is probably that it's running all the time (and its power usage might not be calibrated for the battery usage screen). The stats won't know at all if e.g. the kernel gets stuck in an infinite loop and drains the battery...
Personally, I only trust the info the battery usage screen gives me about apps. If an app has a high percentage, it's probably not right. The rest of the breakdown is mostly bogus.

Well something is eating battery fast.. I have my xoom and my infinity sitting side by side right now and my xoom is at 80% battery after 2:30 hours on while the Infinity is at 62% after 2:41 on. So the infinity is draining battery about twice as fast as my xoom. And the xoom shows the top battery usage as the screen where wifi isn't even making the list.

There are already some threads that discuss this topic. The battery meter has a bit of a bug where it shows the WiFi % based on how long the wifi has been connected rather than how much actual power it has used. Mine does the same thing with 85% battery atm but it has been running off of the charger for 1d 13h and still has 37% left.
It is a battery meter issue and not an energy drain issue.

Xoom is now 68% after 3:30
Infinity is now 50% after 3:40

Well, the Infinity has more hardware to give power to.
However, my Infinity is at 62% after 10 hours... Most (about 80%) of that time, it's been sleeping (but on), though. Did you actively use both your Xoom and Infinity during the reported time?
How does the detailed battery usage screen (touch the graph in the normal battery usage screen) look? Here's mine (the gap is a reboot):

Yes I've been kinda using them. I've had them in google plus and swipe around every once in awhile.
I left for lunch and turned them both off.
infinity is now at 40% and xoom is at 55%. a bit over 6 hours since both were pulled off the charger. Screen has been on over 4 hours.

Here is the current status of infinity 37 percent

Here is the picture of my xoom at 53%

From just eyeballing the two graphs it looks like the infinity sleeps better where my xoom is staying active constantly. None the less when the screen is on the infinity consumes power quite a bit faster.
It is clear that the xoom does quite a bit better on battery life than the infinity.

Mine does this too, but battery life is solid

Battery Drain
I just got mine yesterday and the battery drain is unexceptionable. I fully charged it last night and then was off and on it this morning before going to work. After getting into the office it was more than 50% drained and before lunch it was well below 30%. I have the TF101 and it hasn't been charged in two days and it is still at 79% with everything turned on.
I have not had a chance to look into this but I find that amount of drainage excessive.
On a side note I pretty much just have the stock apps running on this. I did just do a cold boot so I will see if that helps at all.

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.
Sent from my ASUS Transformer Pad TF700T

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] New tf 700 poor battery performance

Best buy swapped my Prime for the infinity and so far it is pretty good except the battery life is terrible. I read it should improve after a couple cycles but I don't see it improving dramatically. On my Prime I could charge it once every 5-6 days with moderate use in the evenings. On the Infinity I am only getting 2.5 hours of screen time and down to 30%. Not even close to what it is supposed to get and I mainly use just web browser and WiFi everything off including sync and dim the screen.
At first the battery was so low it would not even turn on until it charge overnight. I read this is normal but I wonder if it sat for too long and the battery was damaged. It came loaded with 9.4.5.30 and I have not updated yet from that version. Should I exchange this for another one? Thanks.

Yes that's poor battery time.
Is your tablet's serial number in the C70's or C80's?
Kind of strange it was .30 instead of .26 as a brand new tab.
Check the performance level setting.
Otherwise I'm not sure.

bad battery stats
Sure its poss to get one with a bad battery or charger...but...
install the std jellybean power control widget ...its in widgets... and see if all your radios and svcs are on... if you have 3 radios on and sync and brighteness up ..your batt time will be toast....
if that doesnt fix it... do a FACTORY RESET.... that fixes this issue many times....
if that doesnt fix it.... RMA THAT SUKER...

Im in the same boat...my TF700 can barely last the day w/ intermittent use let alone steady use via gaming or videos. My TF101 can go a few days w/ out a recharge and it used to get a lot of use. I am wondering about a hard reset...did that work for the OP?

I had it swapped for another unit which has a similar serial number (CAOKAS...) and I am getting the same results. The best battery life I can get is just a little over 4 hours screen time and 3 days since last charge. Here is what else I have done:
-No GPS or any google loc services checked
-No Sync
-brightness at less than 25%
-disabled most stock ASUS apps
-rooted and used battery calibration after full charge from 0% batt
-Using Balanced mode, never performance mode
I mostly use for web browsing, maybe 80% of the time. The other time simple games like solitaire and majong. Thinking about getting it swapped again. Maybe the store got a bad batch or something. I am also coming from a tf101, tf201 and used to get great battery life on both of those tabs. This one however is worse than my lenovo laptop and my sgs2. Any thoughts?

To be honest that sounds about right - I get approx 5 hours screen time on mine without the dock. I had a prime before and the Infinity uses a lot more juice.
If it is sleeping I can probably get 3 to 4 days out of it - never really tested but it only loses ... say 5% max overnight.

With WiFi turned off I get about 9-10 hours, with it on, 4 at most provided I don't use music or videoplayers. The WiFi antenna drains juice like a vampire. (the non-sparkly kind.) It's much more powerful than on any of the previous tabs.
Sleeping.. well, it's been sleeping for about 2 weeks now, let me check.... 82%. WiFi off at all times. If I leave WiFi on whilst sleeping it's dead in 4 days.

[Q] Awful battery life - just me?

I got my Nexus 5 on Monday and have been pretty happy with it so far. Today was the first day I actually had to be away from WiFi for the day and the battery life has stunned me with how poor it has been. I haven't seen battery drop so fast since I had my Desire HD. I took it off charge about 9am and at just after 8pm as I type this I'm down to 10% with under 2 hours screen on time. 100% to 10% in around 10 hours with less than 2 hours screen use.
Has anyone else had this poor battery life? I'm going to let it run down completely, install GSam and see if it happens again but from what I've read on a few reviews (The Verge was the main one) this seems to be almost normal. I would be unhappy with battery life this bad after two years, not two days.

The good battery apps like BBS are broken on KitKat.
But your battery life is not normal. Mine is quite good, about what I would expect. For reference, my GS3 would use 0.2-0.4% per hour while idling during the night. I can't get real numbers or monitor wakelocks on this phone yet. But so far, seems at least somewhat similar to that.

Today was the first day I actually had to be away from WiFi for the day and the battery life has stunned me with how poor it has been. I haven't seen battery drop so fast since I had my Desire HD. I took it off charge about 9am and at just after 8pm as I type this I'm down to 10% with under 2 hours screen on time. 100% to 10% in around 10 hours with less than 2 hours screen use.
Has anyone else had this poor battery life? I'm going to let it run down completely, install GSam and see if it happens again but from what I've read on a few reviews (The Verge was the main one) this seems to be almost normal. I would be unhappy with battery life this bad after two years, not two days.

We can't really answer about your phone without knowing your usage habits. I mean, what you posted doesnt seem bad, especially if you're in a crappy signal area or play games.

my battery has been around 20% better than on the N4

Coming from an iPhone 4, I am shocked by how much faster Android is sipping on the juice.On my iPhone, I would probably be around 70% 7 hours into the day, my N5 is at 50%.

47% after 11 hrs for me

A brief summary of my brief usage. I haven't played any games at all since I got the phone and the only usage has been social network apps and very light browsing of around <20 minutes. Oh and I made a call that lasted around 15 seconds. Everything else is stock setup. I have unlocked the bootloader but I did that prior to setting it up due to it wiping everything in the process.
Basically I've used it as much as I'd use my Nexus 4 and that wouldn't see so much as a 30% drain by now. The only thing that I am looking at as a possible cause is that the phone defaults to wanting 4G only. I'm not on a 4G plan or in a 4G area but even with that Mobile Standby is only showing 4% battery use. Suffice to say I switched that to 3G when I saw it just before posting. As I said, I'm going to drain it completely then charge to full and watch it very closely but I wanted to get thoughts while I waited.
I have contacted Google to see if there are any known issues that have popped up but the response I got just suggests turning off practically everything! Why would I opt for a powerful phone just to turn off sync, location services and anything that makes it a smartphone? The baffling one to me is suggesting I switch to AIRPLANE mode if I'm not near WiFi! I didn't buy a WiFi only tablet, I bought a phone!
"If you know you won’t be near a mobile or Wi-Fi network for a while, switch to Airplane mode"

I have been very pleasantly surprised with the battery life with my Nexus 5, I have noticed however that Google Location service likes to use battery power, more importantly - GPS - way too much..
However, I leave it on and even still it easily lasts me a day of use, with around 30-40% left depending on how much I use it.
What are your highest apps in the battery use screen?
Try turning off Google location services.

I am really pleased with battery life. Around 30-40 % left at end of day.

I saw similar with the Nexus 4 but refused to switch off location services and it seems ok. I've attached screenshots just taken. It seems I was a little off with my browsing estimate which shows 36 minutes in Chrome but still hardly astronomical.

OK so far the general opinion seems to be that it's just me. That helps me eliminate the phone and / or battery just being awful so thanks guys.

I'm at near 11 hours and am at 69%.. with an hour screen time. Not great but it easily gets me through the day. By the time I plug it in tonight it will probably have 20-30% and 3 maybe 4 hours of OST. That's more than enough for me
I should mention I have location off.. and only turn it on if I'm going to use the GPS
I also have Google Now off I don't need those flash cards to tell me how long it's going to take me to get home.. it's useful sometimes but I rarely look at em.
I'm pleased with my battery so far.. for the super heavy user they definitely wouldn't get a day.. but for me I'll get it easily.

its been pretty terrible for me with identical setups as other devices.
it has me seriously contemplating going back to my htc one. overall i do love the phone tho so hopefully I get a better idea when betterbatterystats is updated.
Few things with battery thats annoying me is google services kill this phone worse than any other ive owned. Even with google now disabled and location disabled. Also my daily drive to work I always use waze w/ screen on. With my other phones (htc one / n4 / iphone 5) i generally lose between 10-15% battery. On this phone im easily losing 25%.
I have access to charging so not a huge deal for now. Its a new os update so maybe it will get ironed out.

you are forgetting you are having a full HD and quad core phone now.

Ahh you got that google services bug eh.. that will kill any battery

Despite not wanting to I did a factory reset and installed a handful of apps, nothing that should cause issues anyway. When I got to Twitter though just after installing I noticed two warning notifications crop up that I remember just dismissing without thinking last time.
com.google.android.gsf.login
com.google.android.calendar
Both state they need installation of Google Play Services. I've ignored them for now so it'll be interesting to see if they have anything to do with it. I know the screen is going to be using more battery than I'm used to when it's on and notice that in battery use it's just everything else.
Friday will be the ultimate test of sorts. I've disabled WiFi, I'm charging it up and have disabled a few location things I don't care about. If it goes down hard again then it's going back.

And a MUCH larger battery

My battery life over the last 3 days on the N5 has been equal to and a little bit better than my GS4 I've had since launch. Very pleased

I don't think what you're getting is that out of the ordinary. Between screen time and cell reception (the largest contributors to battery life) you could easily be seeing 'normal' battery life.
Don't expect more than 3.5 hrs of screen time, especially if you have reception issues when not on WIFI. And I'm talking 'normal' computer/dev/IT guy usage (e.g. using the phone as it's intended aka using google now, using one or two emails with push sync, using music services occasionally and sparingly during a day, NOT running in airplane mode, not disabling a crapload of smartphone features).
