[Q] A700 Battery drain - Acer Iconia A700 and A510

Hey guys, I´ve been using the Acer Iconia Tab A700 for a few weeks now and I am quite happy with it. One thing that bugs me though is the battery drain: The battery, even with heavier use, lasts at least for 2 days or even 3, but that´s not the problem.
It´s not the battery drain while using the A700, it´s the battery drain while nobody is using it which bugs me. Is this normal(because of the high resolution, Tegra 3...)or might this be some bug or application(I have no idea what could cause that since I dont sync automatically and I only keep a limited amount of apps installed+I deactivated a lot of system apps) that causes heavy drain, what are your experiences?
I´m on current stock JB 4.1.1 and not rooted.
Thanks for any advice!

I've never had problem with battery drain using the A700 while it is in standby mode.
Maybe you can check your wifi sleep Policy in wifi settings, maybe it's on.
Or maybe an app background service keeps using a bit of your processing power.

I disabled it now, gonna post if it solves it since I dont see any app that could drain that much battery in standby.
EDIT:Not much of a change, could it be that the reason are my 3 Google-accounts(no automatic sync enabled)?

[Q] Android OS taking up tons of battery on ICS on Xoom?

Hey all
I am loving ICS on my Xoom. However, I have noticed that "Android OS" is taking up tons of battery, with high awake times. I have had it unplugged for about 3 days, and the screen has only been on for like 2 hours. However, "Android OS" is the highest battery eater on the list and has kept the device awake for over 10 hours. Anyone else seeing this? I am having the same problem on my Galaxy Nexus. Thanks for any input.
Have you tried CPU Spy? Mine shows deep sleep when the screen is off. Also screen is the biggest battery user, by far.
Yeah. I used it and it said that it spent 2 hours at 1000mhz (amount of time the screen was on) and 12 hours at 216mhz and 76 hours in deep sleep. That 12 hours is taken by Android OS, and I don't know why. It is killing my battery. Does anyone know why Android OS is staying awake so much?
It is probably apps that are trying to sync. See what you have that might be trying to update/sync.
You also may want to try uninstalling some older applications. I think I read somewhere that some older non-ICS optimized apps can prevent the OS from sleeping.

Do you know of any that are especially problematic?
I have 120 apps. Isolating the problem is going to prove to be difficult. Any ideas which ones? This has been happening with my Nexus for 3 weeks now, nobody else is seeing Android OS taking up a lot of awake time?

Just wipe your system clean and reinstall your apps. That will fix all your ICS upgrade issues.
Are you syncing email via activesync? If so, turn it off for a while and check if it makes a difference. This is what makes android os go through the roof for me on the tablet and the phone!

Is that 120 downloaded apps or 120 altogether (including system apps)? Either way, disabling auto-sync and background data before putting your Xoom down could/should help curb the excess battery drain. The only issue with that is certain apps, like Market, won't function without background data enabled but that shouldn't be an issue if you won't be using your Xoom for a while. You could search the forums or Google on how to create scripts to disable/enable background data and auto-sync for you when you put the device to sleep and wake it back up, respectively. Or just search the Market for an app that does that for you.
Do you leave your wireless radios on (wifi, bluetooth, etc.) while not using your Xoom? Setting wifi to disconnect while sleep may also help.
Thank you all for your input, however I think many people do not understand what I am saying...
I understand how to reduce battery drain IN GENERAL, what I am asking is, are people seeing battery drain faster overall on ICS compared to HC? I am, and I think that Android OS is the culprit. Is anyone else experiencing this?
Thanks!
You know, I had the same exact problem when I installed the first fully functional EOS ICS rom for my Verizon Xoom. The Android OS kept draining the hell out of my battery. I went from having about 5 days of battery life to 1 or two tops.
I decided to try a different rom. Since I don't have Mobile Internet, I decided to experiment and installed the Wingray Version of the CM9 ICS Leak(Kang) and I haven't had this issue since.
So I'm not sure what fixed it, was it because I tried a different type of rom, or was it because I downloaded the Wingray version? Not sure, but either way the problem stopped.
Perhaps try a different rom if you're rooted?
I am experience this issue on my Nexus. Try using easy batter saver. It extends my battery life very well.

I'm seeing some of the same issues on EoS nightly 49. I'm down to 88 percent with barely any use. 14 hours of up time. Android OS at 3hrs and 27 mins up time.

I'm not, if anything ICS is giving me better battery life than HC. Even considering I'm now overclocked and using my Xoom a lot more.
I think a lot of people misinterpret the battery % used though. Just because something is using a higher percent of battery does not mean its sucking your battery down, there will always be something at top of that % list, it doesn't mean there's a problem. It's a relative list. It's entirely possible (and reasonable IMO) to have Android OS at the top of your list if you've used your device for only 2 hours over 3 days! You barely used it, what would you expect to be at the top?
that's a known problem,
Android OS is also taking up a lot in the stats for e.g. the Galaxy S on its ICS port
a related question though:
I'm mainly using my Xoom for ebook reading (PDFs via ezPDF and/or repligo reader) - which ROM in your opinion offers the better battery runtime
Team Eos ICS ROM
or
the Team Tiamat Moray ROM
?
Many thanks in advance !
Android OS battery bug 4.0.3
If your android device has been off for a considerable amount of time, Android os should not be at the top of battery usage list; phone idle would be in that spot under normal situation. However, there is a battery bug in 4.0.3. After installing 4.0.4 on my Gnex it fixed the problem (from my understanding 4.0.4 was only for the Gnex as its a newer device and the Xoom wifi is slowly becoming obsolete). I'm guessing this will be fixed in 4.0.5 that will be released sooner or later... my guess is later with aging devices.
My Wifi only Xoom with Team EOS is getting 4+ days of battery life and my screen is whats taking most of the battery. I am using the latest nightly as well as the latest GAPPs. There is something running on your Tablet that is casing the problem you are having. I am having no probles with ICS at all and having great battery life. Have you tryed using maybe setcpu to setup a screen off profle. I would maybe think about doing a full wipe and starting over with the latest of everything.
My android OS was at the top of my battery usage (74%) even when in sleep mode. I used to get 5-6 days, now I get only 2 at best.
I disabled wireless and the drain goes away, android os goes back down to 2-3%.
Any ideas?
ICS 4.04 Xoom WiFi only.
Thanks

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.

P6210 - Huge Battery Drain on ICS

Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.
Tried it both ways...wifi on and off.
Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.
I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?
Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.
i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.
for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:
I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.
I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.
i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.
My battery usage on CM9..

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.
I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

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 Drain problem?

Hello xda
I've been experiencing problems with my Desire S
Basically I've been having massive battery drain when on a data connection (wifi and mobile data), my battery gets fully discharged within an hour.
This sort of thing never happened before and I haven't installed any apps (that I know of) that may contribute to the huge drain.
I've installed Better Battery Stats to identify where the drain is coming from, and from what I can gather (with my limited knowledge of BBS) is that the sync with Google whenever I'm online's the culprit. Funny thing is this never happened before, and I haven't changed any of the sync settings for a year now.
Now could my battery be shot? or is there some way to manage this drain short of replacing my battery? (like rooting etc.)
Also my battery used to get a full charge after being plugged for about 3-4 hours. sometimes just 2. Now I plug it in for over 8 hours and the best it can go is 80%
Some info about my phone:
Desire S
1 year plus with me
unrooted running Gingerbread still (yeah I know)
Thanks in advance!
TL/DR: 1 year old phone drains itself when online on the internet, could battery be shot, or do I just need to root (or something)?
p
There is a very high probability that your battery is shot. Replace and check. One physical warning that the battery is going that it tends to swell up a little bit making it difficult to remove from the phone. Dont know whether it happens with all batteries though.
thanks guy
Now tha you mention it, my battery cover isn't flush with the rest of the phone. Will still have to check though if it really is swelled up
