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.

Im on frosty JB and randomly my phone just starts taking forever to charge. I left it charging overnight and it only got to 81%. I usually get to full battery in a couple of hours.
Anyone know whats up?
Sent from my SGH-T999 using xda app-developers app
I'm running the same rom and I can tell you that every since I switched to JB, other chargers take longer to charge my phone than the original. If you are using the original, make sure you don't have an app preventing the phone from sleeping or possibly have your governor set to performance.
If I remember correctly, there is a "fast charge" setting somewhere, but I can't find it on my current (Darth Stalker) ROM. But other than that, you could A) turn the phone of while its charging overnight; or B) enable power-save mode and/or airplane mode while you are sleeping and the phone is charging. You could also turn off your data and wifi while charging overnight because its not like you'll be posting to Twitter in your sleep
Okay ill try out what you guys suggested but its just weird because it never did this before. It started happening when I flashed cm10. When I noticed this I flashed frosty jb back and the problem presists.

So today I've installed latest MaximusHD rom for HTC One X, and everything is super fine, except for one thing - when I'm trying to connect to my Skydrive (using official app) while on Wi-Fi I just can't do it. After awhile it just says that I should check if I have a connection. The problem does not occur when I switch to Data Transmission. Other apps usually are able to connect but it seems slower than when using Data Transmision.
I have installed the WiFi update, and when using Google Play, or browsing the internet it seems to work just fine... I also switched from Superuser to SuperSU, but the problem occured before that so I don't think it had anything to do with that (noob question - which should I use? Superuser was there by default, but is ist actually better, or there is no big difference?)
Have you tried uninstalling and then reinstalling the app?

I tried, it's still very slow.
Other odd thing is that when I turn on Data Transmission it's always showing the "H" symbol, even in the places where it previously showed "3G" or "3.5G", now it never switches. What does it mean? The speed seems fine though.
This happened to me too. And it's happening to YouTube and google play.
Could it be because I didn't do the OTA update?
In that case i have a little question: if I update the OTA do I/will it wipe all data?

Well I did the OTA update almost right away (after intalling few apps), and I saw the problem after that, so I don't think it has anything to do with that although it's suppose to fix WiFi. Oh and it didn't wipe my data.
EDIT:
Well I can't post in MaximusHD thread yet so I'll ask here, does everyone using this rom experience such a tremendous drop in battery life when using Data Transmission? On WiFi it's normal, but when using cellular it drains 5-10% in 10 minutes... That seems absurd.
bump. Seriously? Anyone knows if this problem with power drain when using cellular data transmission is also present in other clean Sense 5 Roms? Or is there a way to fix that, or maybe there is an update underway?
I just switched ROMs but was getting a full days use out of a charge. WiFi at work and home all day. So I never really used hspda.

Yes! It does this for me too. It seems to drain at something like 1% per minute for me when I have mobile data on. Wifi also drains it quickly, but not as fast. I posted about this in the Maximus thread (some other issues too) but nobody has replied. Good to know it's not just me.

Yep, hopefully there is going to be some kind of fix, I really wouldn't like to go through the whole configuration, app instalation, etc. process again.
Ok, so another thing is - some icons in one of the folders on my home screen disapear. It's always in the same folder, and only in this one, others seem to be unaffected.

Issues I'm having:
1. Crazy battery drain when I enable wifi, but particularly bad when I enable mobile data. I have a Tasker profile where if I enable wifi and connect to my home network, autosync and GPS are enabled for 2 minutes then disable themselves. Last night my phone was on 61%, I enabled wifi, and immediately it dropped to 56%.
2. When I go to bed at night I turn my phone off. If I put it on charge at night it gets to a certain point and the phone switches itself on! One night last week it switched itself on at about 89%, so I switched it off again, and about ten minutes later it switched itself on again!
3. I use Google Calendar, not the HTC one. I seem to be unable to disable the HTC calendar - the only option is to "freeze" it in my backup app.
Aside from these things, I really like the rom, but these three issues are making me wonder if I should try something like ARHD and see if the same things are present there.

Well I don't know how it is with the phone turning itself on, because I'm not turning it off to begin with.
The thing with calendar - it seems to me it was also like that when using official Sense 4+, so I don't know if it's fixable.
I think I'm going to switch to ViperX Sense 5 Rom, people seem to say good things about battery life in this one.

Yes, I know some people think the idea of switching a phone off is somehow weird, but I turn mine off at night. As an experiment I just switched my phone off here in work, plugged it in to charge it (it was on about 93% - charged overnight and it has lost 7% since I switched it on when I got up for work at 5.30) and lo and behold it powered itself on when it reached 100%. I don't want this to happen.
The calendar on Sense 4 could be disabled - I know this as I had it disabled! I prefer the Google calendar, so I disabled the HTC one. On this ROM you can only hide it, or backup apps allow it to be frozen, which is what I've had to resort to.

Well then since nobody seems to know what to do in our instance, and I have no idea if there is some kind of update for MaximusHD underway, we propably will have to switch the Roms. I usually had the mobile Data Transmission turned on all the time when outside my apartment and while it did drain the battery more than WiFi it still was enough for 8+ hours of being on with medium usage (sometimes with battery saver option ticked when I needed to be outside for a longer period of time). Now the phone would be dead after few hours.
EDIT:
Today I switched for ViperX Rom, and all of the issues I wrote about seem to be gone, Skydrive app no longer has any issues with connecting. Although I'll say something more about batery life in 2-3 days when I'll actually have a chance to see how it works. In general I can say that this ROM is a lot more customizable, and has lots of tweaks (greeat ones) I haven't seen in Maximus, but still I'll wait for a few days with my final opinion.
Ok so after using it for a few days I can tell that the ROM itself is just better in sheer terms of funcionality. First thing I noticed is that I can now put more than 16 shortcuts into Folders, the icon grid in app panel is 5x6 so now I have 3 pages to scroll instead of 7. WiFi seems work more stable but I can't say that it worked bad in MaximusHD. When it comes to battery drain while using Data Transmission - it's still there, but after a few cycles of charging it seems to get better bit by bit, if it still changes I'll let You know. ROM comes with lots of additional tools, and allows heavy customization, and reclocking the processor for better battery life. And that's just the tip of the iceberg. I don't know what about the phone turning itself on, because I don't switch it off. In terms of the callendar I also use gogle one and I just turned of sync options in the one provided by htc. Also I'm not sure if while installing the rom You are able to choose not to install the HTC callendar.

I've gone back to my old Orange-branded 4.1.1 / Sense 4+ build. Battery life has gone through the roof, HTC calendar is disabled, everything works, no problems. As for the phone powering itself on, well, something odd happened there...
When I decided to go back to the old build I restored my Nandroid backup and reflashed my old boot.img, taking the phone back to its old setup, and all seemed well, but that night I switched it off at bedtime (still find it weird that so many people think I'm freakishly odd for daring to switch my phone off from time to time) and lo and behold, some time later, it switched itself on again! The next morning I did some searching about removing the Clockworkmod recovery, followed the instructions, and also relocked my bootloader for good measure, and guess what? Since then it hasn't powered itself on while charging. So all I can gather from this is it was either Clockworkmod or having an unlocked bootloader that caused my phone to power itself on, because as soon as these two things were changed it has behaved normally.
So anyway, I'm going to stay on this build until Orange get around to releasing 4.2, or my contract expires in April, whichever comes first. Probably the latter, as according to a post I've seen from Orange themselves they reckon the update will appear 3-6 MONTHS after the manufacturer releases it.

Heh I'm alson in Orange (poland), and we got info that the update will show up sometime mid-december. I just got tired of waiting for them to update that's why I ended up with custom roms.
Maybe it was CM fault? I'm using TWRP, tonight I'll turn it off and see if it powers back itself during the night and let you know.
Hey guys!
So I run off of the stock stuff sprint gave me, too lazy and totally happy with stock stuff.
So I updated to 4.3 the other day and my battery drains super fast. Before the update I could go through my whole school day and get home and my battery was at 40% ish every day but it would vary on the day no lower than 25% though.
Today my phone died 2 hours before I even got home which I have never had with any phone that I have owned.
What is causing this and what can I do to fix this issue?
Probably a wakelock issue. Go to the play store and download a wakelock detector app.
I downloaded a wakelock detector app, I will keep an eye on what is says and report back here if any other problems exist.
So I downloaded a Wakedetector app as suggested... the problem still persists. Today after an hour off my charger I am at 80%.
What could it be? I close my apps, I have the brightness turned down, I barely watch videos. GPS is off, connected to my home wifi all the time when i'm home. Never searching for stuff in the settings.
If this can't be fixed can I go back to what I was running before the update?
So I was having the same problem and my husband was having it worse.
I'm on Barebones 4.3 rom and I did the following:
Installed Greenify and hibernated apps I do not use all the time,
Using the built in app manager I turned off the 3 print services apps that I don't use,
then drain my phone all the way, set it charge, once full, unplugged and set it to recharge.
My phone was saying it was 100% but it wasn't really. Did one of those charge to 100% unplug recharge till the time from charging to charged was about 1 minute.
My husband on the other hand is stock ota 4.3 w/ knox. So I did used the built in app manager and started one by one turning off what bloatware I could (kies, print services, other samsung stuff he doesn't use), cleared cache on everything, and some data on sprint apps hoping it would stop them from running. Finally did the same battery charge thing I did with my phone and now it's behaving like it was stock 4.1.2.
I'm using PureKat ROM for my Desire Z, and recently I've noticed that the battery drains so fast when I'm on career's 3G network (WiFi doesn't have this problem). I suspect on Google Play Services and I've disabled to auto-start, wake up and keep awake the phone and most of it's unnecessary services using this tutorial but it doesn't help. I've attached battery usage statistics after charging (all is normal there as you can see). Also I want to mention that 3G is mostly off (especially when it charges) so battery lasts as long as it is disabled (it can last for several days without 3G I think), and charging is really fast!
Has anyone had this problem?
Just to be on the safe side, check to see if this also happens on a stock ROM. I remember my old G2 did something like this. Can't check it anymore because my son killed it when I left him use it.

Thanks for the suggestion! Which exactly stock ROM version to use? And if I do that, it will disable root and restore to S-ON, right?
I thought that the problem was with battery, but when I replaced and tested it again, it still acts the same :/
Can anyone help me?
I think that is normal because my desire z give me only 3 hours on 3g and about 6.5 hours on WiFi and now using htc one it also have quit same battery timing like that !

I think that I've solved it with SetCPU profiles. Battery life is noticeably better now.
