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.

Every so often my galaxy nexus will just get really hot in my pocket and start draining battery like crazy. I stopped all the apps and processes and the battery was still draining. I even turned the phone off but when i turned it back on it just got really hot again and the battery was still plummeting.
I'm pretty sure this didnt happen before I got the 4.0.2 update but might have nothing to do with it.
I even got 2x battery to see if it helped on some useless processes that might be causing it and I though it worked as it didnt happen again for a while... until yesterday.
This happened to anyone else or have any idea what it could be?
You need to more specific, Are you rooted? overclocked? pure stock?...something is causing it to run this way either that or your pure stock nexus could have a defect..any device getting hot is causing stress to the battery and hardware,which over all long period of time will most likely cause the device to break...
Sent from my Galaxy Nexus using XDA App
oh yeah. Its just pure stock
pull the battery out for like 10 seconds...and power it back on,and clear all recent apps..what is 2x battery a app?..or do you mean the extended battery?....

I usually reboot after a update ..just to make sure settings are reset and working properly
Sent from my Galaxy Nexus using XDA App
Usually this is due to a rogue app. Use the built-in battery monitor as well as BetterBatteryStats to identify the app and remove it.
BTW, it's the battery drain causing the phone to get hot. Heat, by itself, will not cause battery drain (not on the timescale you're talking about at least). Just a cause and effect FYI.
clear all recent apps? i turned it off and back on. i shouldnt really need to take the battery out should i? but then after a while it stops doing it??? like when i plugged in the charger.
2xbattery is suppose to be a battery saving app

when i went to the battery monitor it just said the main battery use was exchange services, screen and OS not much else.
plus when rebooting the phone shouldnt this have stopped the "rouge app"?
Some apps will start themselves at boot. A reboot will thus not solve the problem.
As for exchange, what are your settings? Push, or poll? If poll, how often? Are you still getting email?

Yeah im gettin email its on push. It only happens now and again tho, not all the time. Plus the battery saver is suppose to minimize checks and stuff
Is your phone holding signal? My phone only gets hot when it can't find and hold a signal.

This could actually be a possibility come to think of it. Every time its happened I was in a place known as "the bat cave".
Is there any theory on this?
Sent from my Galaxy Nexus using XDA App
Its possible that exchange services was top of the battery use list actually. Would this have anything to do with searching for or holding a signal?
Next time it happens I'll try closing exchange services to see if its that or if it it is I'm not getting a signal I'll try putting it in airplane mode to see if that stops it.

Hi all
After sitting with my stock SGS4 (i9505) for a few months I decided to root (as i had my N7000 and HTC Desire).
About the same time as this my phone began turning off seemingly randomly. At first i thought this may be a ROM/Kernel issue but I have tried a couple including Stock(rooted), Carbon and the GooglePlay Rom. The same thing happens for all of them.
Once off, the phone boots to splash screen then turns off. This cycles. I remove the battery and the phone will turn on, sometimes showing a SIGNIFICANT apparent drop in battery (90% reduces to 3% during this single on/off cycle). A quick charge and restart will often cause the rebooted phone to read the battery at 90% again.
The battery does appear slightly swollen and i'm curious if anyone could shed any light on:
1) does this seem a battery / firmware issue and
2) any suggestions?
Thanks in advance for any help you can offer!
Currently: GooglePlay Rom 4.2.2 PhilZTouch Recovery
Regards
Warnoceros
If you're saying the battery is "swollen" it probably is a battery issue IMO. Especially if you're having problems on every ROM you've tried.
Have you tried going back to stock to see if it's still happening?
Hi
Thanks for replying. I'm downloading stock now so will report in the morning.

Hi,
So, went back to stock (binary counter has moved up unfortunately - didnt read into that before hand). Was still rebooting. Have replaced battery and this seems to have done the trick for the time being. I noticed that the unit did not reset until my google accout restored apps to the phone so there is still a chance it was a bad app i suppose.
Most likely the battery though
Thanks

no matter what phone ive ever had, ive never gotten battery life like aot of you guys do. i dont know how you do IT but ive given up trying.. Even . even with roms i cant. i am on stock wiht note 2 and it is so bad that i can unplug and not touch my phone and it goes to 90 percent with the screen off within 20 minutes . i have sync gps wireless and bluetooth off. and my screen goes black in 10 seconds. one thing is when i go to running programs it shows alot so i use the broom to clean it and then when i check back to ruining programs a minute after, there are lots of apps open again. even things like word with friends that of course wouldn't be open if i didn't open it. have you heard of this/. or is it normal? would you suggest a hard reset? any suggestions would be appreciated. im not as savvy with flashing roms on here as i was with early phones so id prefer to say on stock. thanks so much

Phones aren't the same each one is different. What battery performance I get may not be the same as you as our chips etc may run slightly different.
With that said, the biggest influence over battery performance is the kernel. I run saber kernel 42.4 and get 1% loss per hour with the screen off.
Of course you can try that kernel and see how it works for you. There are a lot of tips threads in these forums but I would advise you to turn off tts any and all sounds on your phone, by that I mean keyboard sounds etc.
Then you need to download better battery stats and greenify. The first will tell you what apps are eating your battery and the second will let you force close the app until you restart it.
Sent from my GT-N7105 using xda app-developers app
+1 for greenify. I would also look at xposed boot manager and recciever stop. Grenify puts programs to sleep and the other 2 stop them starting in the first place. You have to be rooted but you will definitely notice the difference

so recently my lg g3 been dieing over night left at 100% before i go to bed i usually wake up and its at 80-90%
this week my phone died 3 times over night. its really aggravating.
this time when i woke up it was at 5%!!
i thought it was led manager because on the wake lock it showed over 1000 wake locks
so i thought to remove and install a different one still same wakelocks.
this has never happened before when i used led manager.
heres some pictures from gsam and wakelock

What's with applock? On the last image right below led blinker. It was turned on even more than led blinker. Like 32000 times.
What SD card do you have and have you removed it to see if it is the cause. Have you recently installed a new app. Under settings, battery, usage what is using power. Under setting, apps, running what is running in the background.

Do you have any apps not running. You have almost no ram left and everything running in the background. Is gallery continuously restarting.

Back to app locker. Is the vault on board or cloud based? Is it possible it's trying to sync and can't make a connection to the server so it keeps trying.

I think if the battery was bad it would have less internal resistance and charge to full super fast too. Maybe try and swap a battery with a friend if you can or reinstall the stock software and keep your downloaded apps to a min. Maybe install a few at a time and see what you get.
Something just happend. I left my phone to charge and it wasnt charging! The charging indicator was there. I just restarted my phone and it stil lwasnt charging but it says it was charging but the battery stayed the same over an hour.. So i took out the battery and put it back in now its charging correctly
