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.

Confirm the following option is unchecked:
Maps/Settings/Location settings/Report from this device.
If it is checked, uncheck it.
Here's the difference in battery life -
About half the battery drain with the option unchecked.
Thanks for the tip

What are you talking about? Did you zoom in to see screen on/awake usage? Both are about 7.5 hours of idle time.
I updated my phone to JB and followed the battery saving measures and the battery is dropping very quickly.
Before it could last up to 3 days in standby, now I'll be surprised if it lasts 8 hours.
I'll give it another day then try a factory reset if it does not improve.
Anybody else seeing this?
I have watchdog on the phone and it shows zero cpu off time.
Just install better battery stats, there is also a way to dump the same info in terminal but I don't use it. You are looking for alarms apps cause. It's most likely maps, followed by talk, exchange client, or anything like Twitter, FB,g+,stocks.... but most likely maps location settings
Sent from my SPH-L710 using Tapatalk 2
I have been doing a lot of research and the end result is that JB out of the box will eat your battery and yes disabling the settings under maps does in fact help a lot but there is a lot more you can do to get good life... for starters get the simple stuff out of the way, DELETE FACEBOOK MOBILE APP!!!...and twitter and anything that actively accesses the internet in the background... I know this may sound taxing but it is so worth it if yiu just make a bookmark in your browser and view it periodically than have an always active app... next if you are not in a primarily lte covered area set your phone to cdma only... go into settings and go to data usage and here you can see what is using data in the background I.e. facebook... and go there and check the restrict app box.., disable auto brightness and some have said that if you disable sprint connection manager thing you can do even more.... now that one I cannot be sure about I will post results in the coming days of what I find

You are pretty much correct the FB app sucks but I never really had much problems with it.
A lot of these tips though in general (not directed towards you) are stupid.
Like someone said a while ago I refuse to gimp my phone to sip a little bit more life out of it. What's the use of having a smartphone if you're not going to use it like one.
I always have high brightness unless its dark out. I broke my syncs intervals up to about 4 hours per sync and have push notifications from twitter and weather.
With those apps all I have to do is refresh when I enter the app having those syncing all the time is worthless unless you're constantly checking every 10 seconds.
I say I get fairly decent battery life granted I'm on wifi most the time and 7-8 hours with about 2 hrs screen on playing HD games youtube poweramp and my background processes.
Well in regards to the act of extending the life of your battery these are simply tips that you can utilize in the event you are someone who is out for extreme amounts of time.... I average anywhere from 13 to 17 hrs of battery life with 100% brightness, wifi 3g all of my favorite apps... instagram xda kik kindle Skype etc. And 5 to 6 hrs of screen on time. .. so these gimping tactics more than double my phones live time and doubles my life.... but hey if you can get to a charger after 8hrs by all means but for the most part I cannot until after 13 but i do in fact appreciate your incite

Even with changing that setting in Maps I still am not getting the same battery life as I did with ICS. Maps is still coming up as my most used app when I check battery usage even though I rarely use it. Wonder if it may be Google Now causing Maps to keep running.

Oh wow. Sorry from my phone I couldn't zoom in. I see now lol. Thought I saw 90 and 89 or something like that
I had the Maps setting turned off for a few days and also had A LOT of stuff disabled, but unfortunately my battery life (and my wife's as well) wasn't as good as ICS, and quite a bit worse actually.
Sadly, today, it looks like I figured out what the killer is:
Google Now.
This morning, 100% charged, I turned it off. My wife (who still had it on) and I were out and about together for about four hours, we both barely used out phones for that time. When we got home I checked both phones: I was at 96%, she was at 80%.
The only difference that I hadn't already accounted for:
Google Now.
So, unfortunately, it looks to me like one of the two biggest reasons for wanting JB in the first place (Butter being the other of course) turns out to be a big battery hog I don't yet know if there's maybe some setting within it that is a specific problem or if it's the whole thing in general... maybe you just need to disable a card or change an update frequency or something (I didn't touch any so I'm running whatever the defaults are), I don't know yet... but all indications are that's where the problem lies.
That, my friends, sucks.
Well since my phone has calmed down I am getting 13-16 hr easily. Brightness maxed of course and about 4-6 screen on time I will never cripple my phone. Hell I bought it so I can use not to look at. Lol thanks for the post of this though if I'm ever I. A die hard , situation I'll know what to do

Google Now uses the "Report from this device" and "Enable location history" maps location settings to determine your driving patterns so it can suggest alternative routes and report traffic delays. Disabling "Enable location history" will disable the driving pattern suggestions completely.
FWIW Settings | More settings | Mobile networks | Network mode
Changing from "CDMA" to "LTE / CDMA" has gained me better battery life. My wife also noticed the same.
(To save time, I'm cutting & pasting my post from another similar thread.)
> http://forum.xda-developers.com/showthread.php?t=1963689&page=3
"I have had my Galaxy S3 for a week now. Battery life stabilized after the initial syncing, etc. I updated to Jelly Bean v4.1.1 two days ago, and battery life didn't seem noticeably different. However, that was until today. My phone was off of the charger, around 10AM, and had < 5% charge by 4:30PM. I was very busy, so I was hardly using the phone all day. It was in my pocket or on my desk most of the time. One of the only settings I changed last night, was enabling 'Use wireless networks' and enabling 'Location and Google search' under 'Location Services' in 'Settings'. I just disabled both settings, and will see if the battery drain is any less tomorrow. Also, Google Now was off, and was never enabled on my phone. I'll try to post the results, if at all possible..."
So, for me, it seems to be Location Services may have caused my poor battery life, and was definitly not Google Now, as it was never enabled. I'll try using the phone with the settings off, and see if that changes anything...

I do love Jelly Bean; as it is ICS only improved or enhanced. But battery life has definitely taken a hit. I can barely make it through 24 hrs. On ICS I could do a day and a half to two days with really light use. I've tried just about everything mentioned with little change. Good thing I have an extra battery. Thank you Samsung for making a phone with a user replaceable battery.
Thanks for all the ideas/suggestions anyways,

I noticed the huge difference as well. I was walking around Chicago yesterday and not using my phone. After 4 hours I looked and my battery was at 50 %.

Hi everyone,
Like many others I had a terrible battery drain in std-by after upgrading to JB. I've already posted some troubleshooting I performed somewhere else, but since I wanted to update this from time to time and to keep everything a bit together, I'm making this topic, don't shoot me :fingers-crossed: It's my log/reference how I'm fixing my battery issue, and some help for other ppl trying to fix their issue to.
Feel free to add your thoughts.
So, some facts of my case:
- Phone is locked, all stock, with JB.
- Std-by drainage after OTA upgrade to JB with everything working on ICS, was +- 20% over night (7h), no data/wifi/BT/sync or anything else.
- Something is waking up my device every half hour to drain battery.
- Disabeling Google Now, NFC, Location stuff, Sync, etc... did not solve the massive drain in my case (it will help ofc, but is not the root-cause).
- Factory reset followed by the installation of all my apps and settings at once did not solve my issue.
- Factory reset with ONLY activating my google account during initial setup (and pulled in my contacts). Nothing else installed or activated/synced for testing purposes. => Solved the std-by drainage on my phone.
- At this point I can tell for sure that in my case, a rogue app (that worked fine on ICS but not on JB) is causing this problem, not JB or my hardware.
**************************************************************
What I did then:
I tried a few battery apps mentioned in other posts to find out where the problem was, but I was not able to find anything usefull.
Tested in the other direction... Did a complete factory reset again, with none of my additional apps installed (only my contacts), no google now, location or syncs.
The result was 14h with only 4% gone! Good result imo.
So I planned installing a few apps at a time/day to see when it starts to drain again, so I can isolate the problematic app.
Yesterday I installed 6 of my most used apps + a few sync profiles last evening, still a very nice std-by drain this night (was still on 100% this morning lol).
For all those with std-by battery issues, if you don't mind a full factory reset and don't need all your 150 apps at once, try it like I did (clean with no apps, sync or data) to see if std-by drain is back to normal (for testing purposes). Then install 5 to 10 apps per day to see if everything remains ok. My device works as it should be now.
I know a lot of ppl prefere not to wipe their phone and want to find the problem via battery monitoring apps, no problem with that, this is just the way I did it, it takes some time but ok, at least the drain is gone now :victory:
I'll update my findings regulary untill I bump to the winning app

******************************************************************
These are the apps/features i've installed so far and NOT causing the std-by battery drainage (20% or more in 7h):

After disabeling the location report setting in Google maps the battery drain was gone on my hox. Go to Google maps/settings/location and then remove the check mark at something called like report location (I have a german phone so I dont know the exact expression). Once you have done that the battery consumption is less then on ics. At least in my case.
Hope this helps!

How do you check screen time on JB? Seems to be gone in the 'battery' option in settings
do you keep data connection off?
Use gsam to show screen time.
Power save mode turns data off with screen off.

Yes, when my phone is in std-by at night, wifi,data and sync is off.
Another batch of 11 apps installed yesterday.
10pm to 10am = 3% std-by drain.
From those 12 hours there are also 3 hours included which my wifi/data and sync was on with mails coming in.
So std-by battery drain is still very good here! :highfive: Hope the rogue app is in one of my 50 games, no so difficult to eliminate one of those

Any help would be appreciated!
I think you really have nearly answered your own question - it's the syncing that's killing your battery. FB is notoriously bad at draining a battery all on its own and the others may be bad too. The dead giveaway is the phone isn't deep sleeping anymore with sync on. Keep up your experiments but freeze each app/process in turn to see how bad each one is and you'll find out. No need to leave it over night - an hour or two should be plenty to find out. In fact, if you have your phone set for max battery life, it should go into deep sleep within minutes of locking it. Personally I only sync manually and that's including email - but I'm not too plugged in so I don't mind checking a couple times a day manually. It does mean killer battery life though! Really any process that is constantly waking up your phone will do the same thing as fb - Google Now with location history on is another bad one.

I use fb and I get no battery drain from it
Still unsure about which app is the main culprit. Facebook seems like it could be the biggest problem. Attached is my dump from BBS (BetterBatteryStats) I tried the same thing as the night before except I did the following
Facebook Sync: Never
Twitter Sync: Never
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Night 3:
100% battery before bed, background sync enabled.
52% Battery by wake up.
NOTE: 10076 (Wifi) (com.android.vending.Google Play Store): 86.0 MBytes 95.3% was my apps updating just after boot.After all apps were done updating, I put the phone to sleep until morning.
Things I am going trying.
Freeze Samsung Push
Freeze ChatOn
Greenify Facebook
You need to understand that virtually any app that has the ability to poll your phone and push updates to it automatically without you visibly seeing it is going to drain your battery. This includes:
1. GPS
2. Having your data on in general (networks push packets to each other to stay within protocols regardless)
3. Google Accounts (syncs your calender, contacts, people, etc.)
4. Google Now
5. Mail
etc, etc.
I know this is a little off subject but will face book still drain Battery even if you have location off and sync off?
Facebook Messenger was an issue. It kept waking up my device. I have been doing some testing though and have had almost no luck until tonight.
I disabled WiFi before bed with 100% battery. 7 hours later, 91% battery.
I need to find which apps are using WiFi so heavily.
Go grab greenify from play store

I have been using Greenify the whole time. Currently, it looks like when on WiFi apps are going crazy with connecting and waking up the phone. On Mobile, I got much better battery life.
Try backing up all ur data on internal and SD card.. Then do a complete fresh install.

Yes. I have the same experience. When WiFi is on, the battery life is much worse.

Ok Wi-Fi being on won't kill your battery. Maybe you need to set your to, keep Wi-Fi on during sleep= NEVER. That'll help your battey life some what..

I've noticed in GSAM battery monitor that my "held awake" time seems abnormally high. I've attached three screen shots. After being unplugged for about 3 hours, I lost about 10% battery from being on wifi the whole time, and about 20 min screen on time (mainly google voice text and play market browsing). It was idling pretty much the rest of the time. No music, pandora, video, etc.
The "held awake" time is 2:37 out of 3 hours! And according to GSAM, it's Android system that's keeping it awake. Is this normal...?

Yes at all. 3 hours of wakelock for 9 hours of uptime? That is aweful.
One hour of screen time and been driving around streaming music etc for close to two, totaling 3 hrs. Sounds reasonable to me since I was indeed using the phone which prevented it from sleeping. Don't see how I would be streaming anything if the phone sleeps

well in your case it's fine, but I'd think that the OP asking this question in such a way that shows he wasnt doing something like streaming means that this IS extremely high.
Also, your 3hrs of wakelocks in 9 hours are NOWHERE NEAR the OP's wakelocks of 2.5hrs out of 3...

And that's exactly what I mean. I would download an app called wakelock detector from the app store to see what's causing it.

Had that same wakelock, its Google Backup. I turned it off. Settings>Backup&Reset.
Thanks for all the inputs guys. So yeah, it does appear to be Google backup, as you can see in my third screen shot. I just wanted to check my sanity that this is NOT typical behavior. Does anyone know what exactly Google Backup, well backs up?
I did a hard reset (hold down power button for 10s) and so far that seems to have fixed the problem. I am going to keep an eye on it for now, and keep Google Backup turned on. I'll report back if it starts again.
