So I think by now everyone has realized the battery life on our A100's is mediocre. I've actually been pretty content with the usage I get out of mine. What I'm not so thrilled about though is the idle usage. I'll leave for work in the morning with my A100 at / above 90% battery and come home after 6pm with it completely dead. I have wifi set to turn off when the screen does, any app I have that has a sync option is set to 6+ hours, and I've stopped using live wallpapers. Every other electronic device I have can usually last a full day when not in use(my old netbook gets 3 hours of use on battery but 2 days while sleeping).
I've started looking into the "bloat" / OEM apps installed by Acer. Nidus, sync, socialjogger etc... My main questions are; what can be removed, what can I live without or would be better of with a 3rd party app, and which Acer apps can possibly be causing the idle/sleep battery drain? This thing should still last a full day while sleeping, shouldn't it?
Any suggestions? Anyone else have this issue? Thanks!
You could try using Bloat Freezer to freeze apps. I have alot of the acer stuff frozen, and with it in standby, easily goes a day. Things like socialjogger, acer init, etc.
These are the apps I've completely removed from system apps, made a backup of course..
AcerClockwidget.apk&odex
Agendawidget.apk&odex
Aupeo.apk
Clearfi.apk
DTG.apk
LinkToFacebook.apk&odex
MusicA.apk&odex
MyLocationWidget.apk&odex
NemoPlayer.apk
Planner.apk
SocialJogger.apk
Solitaire.apk
Xt9.apk
You can also remove appinapp butyou will loose the games multimedia app I use that so kept it.
Battery life hasn't been that bad on mine. I expected worse, I just picked mine up last week and after reading reading reviews I expected worse.

WOW! I can use mine all off and on all day and don't have a problem. There has got to be an app that you are using that is destroying your battery when idle. If I don't use my tablet all day, it will last 2 full days (with wifi kept on).
That's what I was thinking. I get a decent amount of usage from it; it's when I'm not using it is when I feel like it drains the most.
I started freezing apps last night and let it charge overnight. I've still got to go through my apps and remove a few I don't use, and check to make sure they're not syncing too often. Do you all leave your gps and wifi on all of the time or have them shut off while the tablet sleeps?

My settings are to never turn WiFi off and I always leave sync on; I like getting notifications and app updates. I have a weather app that updates every hour and Pulse news that updates every 4 hours.
I also always leave my GPS on, but there aren't many apps that use it while it is not in focus, so I rarely ever see GPS pop up on my battery usage list.
I do not use a live wallpaper.
I found that with wifi on, my tablet drains about 1.5% per hour when idle.

I suggest other than setting wifi to turn off when screen is off is to use a wifi toggle widget. You really never know what happens when the screen is off if your wifi is really turning off. Wish it was built in to the quick launch though like some Honeycomb tablet.
You can also use setcpu to setup profiles so that when the screen is off the processor stays at a slower speed rather than jumping into high gear when something wakes it up to sync. I've been able to go days without having to recharge (but I only use it for reading books, listening to the music I have on google music and play order and chaos every once in a while). I havn't touched my a100 in about 4 days and its sitting at 62% battery power.

here is my usage, I never turn off wifi no profiles
I don't necessarily think you need to remove any of the stock app. My wifi is set to turn off when screen is off, GPS off unless I need it (apps like facebook will use it when you open it since it tries to get your location for checking in even if you're not checking in). Gmail is left at default but other mail is set to never (I just manually sync it when I open it).
If you wanna go a step further, you can install a wifi on/off widget to completely turn it off just incase an app is trying to use wifi.
With my setting my battery drains about 1-1.5% an hour when screen is off. IMO the screen is what uses the most battery. However though after conditioning the battery for 3 cycles it's been lasting longer.
I was just about ready to return / exchange my a100 so I did a factory reset on it. Lost track of time and forgot to, so I just decided to boot it back up and play with it. Left it alone at around 70% yesterday afternoon, came back home at 7pm today and to my surprise it was at 40% battery remaining. Must've been an app or setting I had that was killing it.
Probably end up hanging onto this awhile longer. Great tablet for the money!

Also can freezing apps brick your tab as well? Or does it defrost itself after boot?

I think with the 1gb ram on our device there shouldnt be a need to freeze any app and it doesnt defrost itself on reboot. Atleast it shouldnt.
Also I found for the most part if an app can be deleted it will let you delete it by dragging the app icon in the upper right in the app drawer. This is probably the safest way to delete rather than doing it in root explorer or TU.
This might be a dumb question but is it possible you have wifi issue that i've had on 2 a100s which will prob cause it to use more battery as its trying to work harder locking on.
It seems for the moment my battery issue was resolved with a factory reset. I have nearly the same apps on it now as before and my a100 hasn't been dying overnight. Don't believe I've frozen anything this time around either.
I don't think ram has a whole lot to do with it. I just figured some of these apps were starting themselves or syncing often, causing the battery drain.

Do you have a lot of widgets that requires syncing like youtube, twitter, weather, facebook? Those are the apps you probably what to check. OR you can just turn off wifi if youre not surfing or streaming.
Here's mine with wifi turned off. It was at 89 but I had to turn on wifi so I can find a screen capture app in the market. I have lots of apps including facebook, twitter, weather widget, which cant sync cause the wifi is off. Have not removed any stock app. I know this doesn't really answer what you asked but I'm just thinking something else might be wrong other than apps. Maybe its your battery not holding correct charge. Have you tried calibrating the battery?
I tried calibrating the battery the first time around. This time (after the reset) I haven't done anything special and have so far been getting 2 days of idle/light use before needing a charge. Satisfied so far. I was mainly concerned that I wouldn't be able to go on a trip without it needing a charge while sitting in my bag for a day without use.

Hi all I just got my galaxy note 2 yesterday but the battery life is bugging me.... I feel that it is not normal.. every 5 minutes or less the battery percentage drops by % 1 even if I am not opening any apps and I have GPS, mobile data and other unnecessary things turned off and just using Wi-Fi with power saving turned ON.. I even didn't used it that much yet, no videos or apps that consume a lot of CPU and I always make sure that I kill apps after using them, currently I am just surfing the web with chrome and it is still inconsistent sometimes it drops after 10 minutes and sometimes after 3 minutes, I also turn everything off except for power saving when I go to sleep but after waking up I noticed that it dropped by % 4 .. sorry for the long post guys but I am very worried and I just want to check if this is normal and if it's not I can get the battery or the whole device replaced since I have a 2 year warranty. I also attached some screenshots if you need to judge from them.

Have you updated your Note to 4.1.2?
I recently updated to 4.1.2 and my battery life has suffered.
Hopefully a new update will fix this.
Judging by what others have written, you should get between 6 to 7,5 hours with the screen on. I plugged mine in yesterday efter 1 day and 12 hours. This includes 8 hours om sleep and 6 hours at work -no time to use the phone at work. I did not make note of the screen on time.
As i write the phone has been on battery for 8,5 hours and the screen on for 1,5 hours. The battery is at 54%
Hope this helps.
Thanks for replying
But my device is still on 4.1.1 and haven't touched the software update option and still .. I am not getting that spectacular battery life everybody is reporting which bugs me since I love my note 2.. even while I am typing now the battery percentage has dropped by % 3

It's that a task killer icon in the top left corner? If so, you might first want to try if your batterylife improves after uninstalling that!
Also find the app called better battery stats on play store. I recommend you buy it and install it. EDIT: there is a free version of it on xda too... Then charge your phone to full and use it normally. When the battery starts to get low again, open the battery stats app and look for "partial wakelocks since unplugged"
There you might find the cause of your problems. Post the screenshot of the partial wakelocks screen here if you need help interpreting it!
There is a free XDA-edition of BetterBatteryStats as well.
I got similar battery life as Dmwitz reported, no idea how some people get 3 or 4 days or 7,8 h of screen-on time out of their device.
I have the same problem as you
Sent from my GT-N7100 using xda app-developers app
That icon in your notification bar... Is that a task killer? If so, then that's your likely problem.
When you use task killers, apps that restart themselves or their services will constantly be starting up again, leading to more battery drain. Let android handle your running apps and only manually kill apps that are frozen or highly problematic (uninstall those problematic apps if you can).
Thanks for your suggestions guys I uninstalled the task killer and will try the battery app now, I will let you know once I try it

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.
Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.
Sent from my SPH-D710 using xda app-developers app
Get a new battery?
Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.
what rom are you on? tw? cm?
Have you used Better Battery Stats? Or the JB release candidate GB08?
Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.
Downlpaf betterbatterystats. And find the wakelocks.

EDIT: Actually I read multiple issues with SG2 and BetterBatteryStats. However your wakelock comment made me stumble onto the app Wakelock Detector. Again I'll run it and report back. Thanks for the point in the right direction.
Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.
Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:

Hello
I have had a massive battery drain problem on my Note 2, a couple of days after the 4.3 update. While being idle during the night it loses 25% to 30% of its battery and while using it I can literally see the percentage drop. I have tried everything that I could find on the net. EVERYTHING! Nothing worked. These included: Factory reset (twice), letting the battery frain completely and then recharging it while the phone was switched off, switching off all sync,disabling bloatware including KNOX components (the actual KNOX app is not installed), installing only a few apps after factory reset, using Gsam, Wakelock detector, Deep sleep battery saver (which could not make my phone sleep), no GPS, no 3G, wifi on only when needed and more besides.
The phone is only one year old and unrooted. On 4.1.2 it had a beastly battery performance of almost 1.5 days of normal to heavy use, with 300 apps on it. Now it cannot go for more than a few hours with the same use.
I cannot say for sure but it seems to me that the drain is the same when it is sleeping and when I am using it. Wakelock has given me a 75% awake time even though I only use it for 15-20% of the day at most nowadays. Battery settings show everything normal, or at least I think so, eg Screen 35%, Android OS 15-28%, Voice calls 10%, Android system 5-15%, Cell standby 7%, Device idle 4%, Media server 4%. The batttery chart shows a constant steep drop all the time.
The problem started one day when the Media server went mad consuming 50% of the battery. After I did the factory reset it has never again been a problem but the drain still persists.
I have also read that it's a mess up between syncing of Samsung apps and Google services, but I have no way of verifying that.
Can anyone help?
Thanks
I had the very same problem until yesterday myself but think I found a solution on the web.. Uninstall Google Search and Google Play Services and the goto the Play Store and wait for them to reinstall and that's it....! As I found that there is a bug in Google Services (Nlpwakelock and Location service)
Hope this helps...?

Thanks. I already have Wakelock Detector on. I mistakenly wrote "defender" instead of detector on the original post. It gives me Viber and Messenger as the most active wakelock apps. But they both were not installed when the problem started. Besides, on the 4.1.2 they created no problems. In essence I believe that Wakelock Detector cannot help much. Whatever this problem is , it is well hidden. Thanks for your interest and help anyway. Much appreciated.

Which kernel you are using? And also i recommend using Greenify. Widgets usually eat a lot of battery, I went from battery lasting only 8 hours to get my battery use only 30% in 8 hours.
What i did: installed wakelock detector, gsam battery monitor and better battery stats.
Monitorized the wakelocks.
Applied greenify to the apps which were waking most
Removed widgets which were waking alot
Installed Toggle 2G.
Kernel settings: 200-1600mhz | zzmoove | AFTR+LPA | Multicore power saving (SCHED_MC) = 0 | GPU = stock settings
Works like a charm for me. Hope it helps! Any question, ask!
I've read all sorts of things about this problem since I updated and got hit. I have too much app data to lose by trying the factory restore (which by all accounts shouldn't change anything anyway since you'd still be stuck with 4.3)
I finally decided to try the age old blackberry cure-all: "if in doubt, pull it out" (the battery). Since the entire issue seemed to be related to battery caused problems (ie slow charging, fast drain, etc) it made a lot of sense.
And it worked.
I think the main reason this isn't more commonly tried to fix issues on Android is the same reason I didn't try it earlier. My case is pretty serious and isn't easy to remove. I'm glad I did take the time to take the case off though or I could have ended up wiping my phone.

Thank you for the suggestion. I have already taken the battery on and off several times. It had no improvement. The phone is only a year old, that is why I don't believe the battery is the culprit. Besides, problems started only after the 4.3 update. Before that it was working perfect. Too much of a coincidence.
Sorry to hear that it didn't work for you
I'm not saying the battery is faulty in any way - however removing the battery and letting the phone power drain completely seems to stop whatever process is running under the buggy 4.3 long enough for it to work again as intended. It's basically just a more thorough way to reboot.
As I said, I've read all sorts of suggestions, many of which don't work for everyone (such as the factory reset) - this is hopefully just one more thing for people to try before they end up wiping their phone in desperation. I mainly posted here in the hopes that others with this issue that may not be forum members can get some more suggestions.
At least for me, wakelock and all the other diagnostic tools at my disposal showed nothing different to before the update. Many other people have found that the Android System is using a lot more of their battery than normal or some other apps are involved - if this is the case, it's likely to be a combination of things causing the issue (the firmware, the drivers, apps, hidden Samsung processes, etc).
Also, for what it's worth, I found that Knox supposedly wasn't installed (when I find it in the apps list, the button to install it is showing...). But it's showing in the list of apps so it must already be installed. I dug through the list of running processes (had to show the system processes too) and I discovered that several Knox and some other new Samsung processes were indeed running.
One other quick tip - If you wanted to check/tweak the 'developer options' and can't seem to find it any more, that's because it's now hidden since 4.2 - go to 'About Device' and tap 7 times on the Build Number. I tried disabling all background processes however it seems this only disables application level processes, not system level processes but if you've tried everything else, it can't hurt to try playing around with some of the options in there.

Sorry to hear that it didn't work for you
I'm not saying the battery is faulty in any way - however removing the battery and letting the phone power drain completely seems to stop whatever process is running under the buggy 4.3 long enough for it to work again as intended. It's basically just a more thorough way to reboot.

Thanks mate
I think you are right. It is probably a combination of many things. I have opened the Developer options some time back. The one thing that I do for sure in there is limit background processes to 4. Besides that I don't experiment much, exept maybe to change transition animation scale. I am actually thinking of rooting the phone and downgrading to 4.1.2. It was just fine before. I can live without the 4.3 add ons.

Problem still persists, even with Google+ and most other Google applications disabled

The only battery apps on my phone are the 3 mentioned above, so I don't know what the battery monitor that keeps my phone awake is. The drain existed before I installed these apps. I have read that Chrome could prevent the phone from going to sleep but it is disabled on my phone.

I faced same battery drainage issue, after installing wanam kernel and freezing all bloatwares through Titanium Backup. I'm satisfied with my battery now.
You can try.

Here is detail-
Disable sync always, enable when needed.
Disable wifi always scan from settings
Display set to auto
Uninstall apps of playstore you rarely use
Use widgets on lock and homescreen as less as you can (I don't use any)
Disable motion on settings
Freeze all bloatwares by TB except allshare and samsung content agent
Install Agni kernel, from agni control app-
profile: normal
Governor: pegasusq
Scheduler: cfq
Don't touch other tweaks, hardly you can tweak sound boost.
THIS GIVES ME A SATISFIED BATTERY STATUS.

Wew 4.3 does have may bugs
Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).
You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.
Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.
Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

Can you check the kernel wake lock section of the same app?

On the off chance that you or anyone else can help me understand what's going on I ran a ~10% drain test and made a picture including information from WakeLock Detector and GSam. This drain seems very bad considering the screen was only on for a total of 16 minutes and I lost 8% power.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

I am rooted. That screenshot was with using greenify :[
I will get that kernel app.

Do you have any recommended settings for that app? I disabled something that I think is allowing me to enter deep sleep more, but I have to finish testing. Thanks for the help ratbags!
Oh I see what's the wrong.
Battery usage give me a wrong information.
My fire phone lasting about 5hrs turning on screen.
Very very good !!
Thank you.:good::good:
Five hours is good??

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.
