Removing Bloatware aka "what can I do to get better battery life?"

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.
Sent from my MB860 using XDA App

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.

The OS isn't always the reason for battery drain, many factors take into play.
How often you use the device.
Applications like widgets, email push.
Wi-Fi. If your not on it shut it down it else is always going to try to find a signal and drain battery.
Bluetooth. same with this.
Using the net.
Things like Google now, it's always running and trying to update info, shut it off of make intervals longer.
These are just some things to take into account, but at all use the phone different, and im not saying the OS doesn't drain but it solely isn't the only reason.
Hope this help.

I seem to be having the same problem. ..

Same here. With sync turned off, google now turned off, and most everything else that eats battery...
In the battery setting is shows that media is eating at least 25% battery.

I'm having the same issue. I read that the media drain could be caused by bad media files, but I didn't have any issues before this weird.

In my experience when you first update to a new samsung rom, the media using the battery is your phone updating the picasa albums...which stinks because it also eats your data like crazy if you are not on wifi and forget to turn off sync until wifi is available.

I've noticed faster than normal battery drain as well on my device. Normally by 4:30pm I'd be at 40-50%. Now I'm in the 20-30% range.
I'm going to try factory defaulting it soon and run it for a day or two. OR I might not even do that and just go directly to Task's AOKP or CM10.

i dont have any issues with battery drain, but i would suggest a full restore after upgrade. dont restore using titanium, just install through playstore. then report back but i doubt it will be an issue

Before everyone jumps ship, may want to try a new kernel. KT and a few others should work on the new release. Just make sure you choose one that works on JB TW and not ASOP.

I have the same problem.. After JB update there is huge battery drain. With average usage it drains almost 100%. Before update with heavy usage I was going through the day.
Maybe I should try KT kernel I don't know. I wiped all after updated, nothing saved from ICS.

It's seem the culprit is the android.process.media.
Each time i bootup,android.process.media is running for about 30 min, non-stop.
I already do a factory reset+sd formatting, but no succes.
With startup manager, i can block that process,but you need to be rooted .

I use the same settings as before i did'nt upgrade yet..i got it fully charge with no texting and calls the next 1hr its already 80%..i think i would try to cycle first my battery for 2 more days..then i'll see if it still have heavy drains..thanks for the response guyss.

Check out my overnight drian! from 1:30 to 10 the average drain is around 4% an hour, Losing about 20% overnight doing nothing.

I just got this phone the other day and immediately updated to jelly bean.Though I have nothing to compare it to my battery drain seems normal. I'm losing about 5% an hour but that is with some use (it's new so I'm playing with it a lot).
I did notice more drain the first day of use (may have been because I was using it a lot) and noticed maps was taking up quite a bit of the battery and I wasn't using it. So I uninstalled the updates for Maps and then re installed it. Battery drain seemed much better after that and now the maps app doesn't even show up in the battery report(before it was about 3rd and it seems kinda high on yours as well though you may be using it).

i'm noticing about the same battery consumption as the stock ICS rom. about 1~2% per hour when idle and sitting, 2~5% per hour listening to music over bluetooth with the screen off, and 5~10% per hour surfing the net and watching videos and stuff.

Well after doing probably 5 resets on my phone , it seems like everything is working fine . I was having issues with the battery drain ,internet not connecting, and phone calls taking 2 minutes to connect.

I was having issues with high battery usage as well after updating to JB.
I froze most every app and widget associated with AT&T and Samsung (with the exception of AllShare) and flashed KT747 kernel and set governor to ktoonservative (default settings).
I am really never a heavy user during the day, but with the same usage I had on ICS, I average 15.5 hours (with the phone at approx 15% when I shut it off to charge) - screen on time between 2.5 and 3 hours; call time between 45 min and 1.5 hrs; media (which seems to be a big battery hog) only about 6 minutes. I use bluetooth exclusively, so that radio is on all the time the phone is on. I keep sync and background data on, but only turn mobile data on as needed.

battery draining too fast new or old

im on a stock rom not rooted and new battery and old battery both discharge really fast. Totally dead in 5-6hrs light use. Im guessing there is a hardware issue with the phone as this isnt normal. Any ideas?
lets see I did a factory reset after Jellybean update
changed the battery for a new one
biggest power drain is showing up as screen 33-39%
I have the thing on power saving mode and mobile data I turn off when not in use.
only thing I can think of that I didnt try is flashing another radio. But I doubt thats it because ive put it in airplane mode and it still looses power fast.

Get Better Battery Stats and check your wake locks. A lot of information in that thread. Might have a rogue app draining you.
Edit: also screen on is always going to be your biggest drain. Keep brightness down as much as you can. App called screen filter is good for achieving lower brightness than system allows. You could try the ktoonsz kernel, undervolted as well. Turning off sounds in settings (key press, vibrate, etc as well). Toggle data and WiFi when not using. These are just some basic suggestions.

This is my second s3 and the first one never had a problem going 10-12 hrs normal use. Im thinking it is a hardware issue as I did a factory reset and it still persists on fast draining.
Edit.. I just disable google talk maybe that was causing it?

It's not Google Talk. Check your battery and it'll show you what's drainage ng it the most. Also check screen brightness

lol sd card?? well I tried it anyway and no, it still drains like a pissing racehorse. Ive noticed this phone gets pretty warm sometimes even with light use. Im not sure what is causing this but must be a factor in why the battery life is so poor. When I talk on phone, not very often, the ear piece actually gets hot. Im gonna send this puppy to samsung and see what they can do.

GSam Battery Monitor can offer better details about your battery usage, including wakelocks, cpu usage, etc.. It's more detailed than what Android offers.
I'd also recommend using an AOSP based rom as they include out any carrier/Samsung services that may adversely affect your battery life, particularly in a fringe coverage area or with many sync and push items. I'd also stay away from powersave mode for the time being.
If you want to know for sure, I'd do something like this:
- update PRL on current rom
- wipe and format everything in CWM
- flash rom as per developer suggestions
- wipe battery stats
- boot and do not sign in with your Google account (very important!)
- do not install or restore any apps
- turn off auto-sync and leave data on
- enable auto brightness
- confirm that phone signal is somewhere between -50 and -90dbm
- turn off phone and charge overnight
- turn on in the morning and use normally for the day
- install GSAM if issues persist
Please post back with updates.

It could be a hardware problem also you know.... if something ground off in the phone then the battery will drain faster than anything....I had a n96 with a grounded problem and it use to dead in 4 hrs....

[Q] N5100 Battery Life

Was skeptical about the N5100 battery life since it only have 4600mAH battery.
Now that I have bought it, it seems my worries are confirmed.
I'm running stock rom, only rooted it without other modification.
Installed and have greenify running. Not using any sim card, only using it on WiFi.
Playing a video using MX Player, drained up about 20% of battery for a 45min video. That's rather heavy imo.
Normal browsing and reading forums eats up about 4% per 6min of use.
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old.
Btw the above test were with Power Saving mode(CPU and Screen) and screen brightness was at 25%~30%. Currently on 4.2.2.
And does using the S Pen eats up significantly more battery?
Thanks in advance for the feedback.

Do a search on battery and charging by me, in the Q&A threads. I won't repeat myself here, but I go into how to correct drain issues. Many developers will push their apps for calibration. The real trick is discovering what is doing the drain. I have seen for myself how one app can do a lot of damage with media. Normally I get 12% per hour on battery usage while Miracasting Netflix to my tv, and about 10% on normal usage with WIFI always on. I have MXplayer and a bunch of apps as well running so I am not going to get the same power savings as with a cleaned up stock ROM without any apps, what would the point of having a tablet if that is the case???? I guess peeps like to show off when it comes to numbers. I like to show off when it comes to usability and function without all the apps get in the way.

my battery stats
I'm running CivZ-FLEX-BEAM-REV3.6.2 ROM.
Installed and have greenify running. Not using any sim card, only using it on WiFi, even off the WiFi before I off the screen.

Here's my battery stats:
Is this normal? Or is it my battery has significantly degraded? Cuz I bought this 2nd hand 8 months old, now 9 or 10 months already.

From what the graphs show... it looks like the battery could be going bad, as there has some that say Samsung is aware of bad batteries in some units. You could contact them, but you will need to un-root if sending to Samsung for repair.
Since you are rooted, I suggest installing xposed framework and install Wanam DVFS Disabler for Xposed. It is a standalone utility from the complete Wanam xposed app. Once installed make sure both xposed is functional, and the app in xposed is enabled. These apps act as a separate process from the OS. So installing them requires user interaction for activation and updating, along with a reboot most of the time.
Once they are running... it is best to turn off the tablet for 1 minute and then plug in the USB charger and wait til it is showing 100%. Then turn on the tablet. You can unplug the USB power cable and wait 1 minute, then plug it in. Take note if the charge takes less than a minute to get to 100%. If it takes a minute or more... you will need a stop watch, as it should take about 15 to 20 seconds to go to fully charged, unless you have music or media running at the time. If it does charge quick, you can then disconnect and do another days worth of use and check your stats. Hopefully disabling DVFS will cure your issue if it is not battery related.
As for unrooting, make sure you do a clean uninstall, and have any apps that require root uninstalled. If running triangle away uninstall that as well. You may have to check within the apps settings to make sure you uninstall properly, as to uninstall from play store or the system may not properly remove the app.

Updated Battery Stats
this is my updated battery stats, now I'm suspecting it maybe due to calibration problem?
My screen on time is now 2 hrs 45 mins, and for the last 45 mins it has been running on that last 1% of battery(but with screen dimmed, as brightness is automatically dimmed and can't be adjusted when below 5%).
Even until now the device haven't auto shut down due to run out of battery yet even though been running 45mins SOT for that 1%.
Calibration problem? I've tried calibrating using calibration apps, which I charged to 100% then press calibrate, but didn't help.

Sudden drop of more than 3% at any level after doing the DVFS disable and properly charging can be one of two things.
A bad battery, or bad charging cable. Yep, I have had two bad Samsung cables, one did exactly what is happening with you, and the other did a melt down at the USB connection on my tablet. If you have a good cable from a Blackberry or a Sony/Ericson device, you can try that. I have moved over to Sony Xperia cables, as they are pretty well built and longer.
If another cable does not solve your issues, I suggest unrooting and cleaning up rooted apps before having Samsung service your tablet. It very well could be a bad battery.

thanks for the reply, I think I'll just resort to sending it back to Samsung to fix it.
Now I have made a nandroid backup already, then I flashed stock firmware, so my device is now unrooted and on stock firmware, however my flashcount is still there, and now I can't run triangle away cuz my device is unrooted already.
If I were to root it, it'll flash custom recovery again then it won't be on stock firmware anymore.

Your unroot sequence was done out of order.
Set USB debug
Root stock rom with saferoot.zip
Install triangle away
perform clear of counters
Verify after clearing in about device that custom is not set.
If so make sure triangle away is set to clear and perform clearing.
Remove triangle away
Remove SuperSU through the settings, clear for reinstall.
To make sure everything is proper... do a factory reset.
Once those steps are done, your tablet should be stock and able to perform OTA or Kies updates, without any issues with counter and root.

[Q] Battery Drain

Anybody else having battery drain since Lollipop? Running stock/S-0ff non rooted. Noticed it eating battery faster so I did the factory reset and restored with htc backup, got better for a few days, now it seems to be eating battery again. Usually I can stream music all day through my bluetooth speaker and go home with over 50%, lately by 10am I'm down to 60-70%.

I've noticed as well. I've had to start using the battery saver app to help.

I ended up doing a full reset again and did not restore with htc backup. seems to be better. Android system was draining pretty heavily in percentage but only had about 20 minutes of actual run time according to the system.

I'm back to easily a full day from charge after turning off location services. I scaled that back a bit and am using appops to turn off location services in particular apps as well, after that and removing my T-Mobile account my battery life is back what it was. That being said this phone hands down is the best battery life on any phone I've ever owned.
