[Q] battery drain

Background:
Got an incredible last august, rooted, tried many roms, loved CM. CM gave me the best battery life and the most functionality. Three weeks ago I crushed my incredible in a bike accident. I was fine, incredible and other items in pannier were not. Long story short, got a new incredible through insurance, rooted, jumped to CM 7 and was immediately confronted with what I would describe as unusable battery life. I wake at 5:30am having charged overnight. Battery reads 100%. By 9:30am I am already below 30% with light usuage. Let me describe light usage. Read an email or two when i wake up, send a few text messages, check the time every 45 mins to an hour.
kernal: incredikernal (smartass governor with multiple profiles)
display settings: carbon copy of those in a discussion on CM7 Automatic Backlight Settings
I have made two changes with this new phone:
(1) I am using both the gmail app and the built in email app to sync an exchange account as well instead of just gmail
(2) I installed google music app and have been uploading my music from my computer for approx 6 days now
The (2) was my first guess as to what is draining my battery but when I view battery use I see display trumps everything (usually around 65%).
I have been trying really hard to figure this out via google but searching has led me to something of an impasse. Most info points to display but I am hesitant to believe that my display settings are incorrect due to the number of users who claim these to work well.
Any help/ideas/advice is appreciated!

I am on my second dinc also. Luckily I haven't had any issues like this.
Suggestions :
1) cm has a builtin set cpu. Just pick a gov and min/max. Let the kernel do its thing.
2) chads beta11 kernel is the best I've tried. It has an Ingenious gov that works great.
3) vipermod. It's a zip that you flash in recovery. Use terminal emulator to lower voltage.
4) battery calibration app. It's free in the market.
Chads kernel and the vipermod are both found here on xda.
Good luck

I will give these a try. I am pretty sure i have already given the battery calibration a go but manually instead of through an app. I assume the app is just doing rm /data/systems/batterystats.bin? I was running both setCpu under CM7 so i got rid of that am letting the kernal do its thing with min 128 max 844 and smartass gov. I am going to experiment with vipermod when i get out of work as I have not read much documentation on it and would like to read before flash stuff that messes with voltage. Thanks for the advice, i will let you know how it goes.

No problem. The vipermod thing you open in terminal. It's very cool and easy. Adjustable voltage on the fly. I'm undervolted -100 on chads beta 11 cm7 99 nightly. 8hrs of hard use. Smooth as butter. Can't remember exactly what the battery calibration wipes. It tells you in the app.

Wanted to bump this to see if any fellow forum members have noticed increased battery drain after installing the Google music beta app? I'm having a hard time figuring out what's going on, I've tried different radios, kernels, etc, but to no avail. Haven't tried uninstalling the app yet (but I don't really want to, its pretty convenient). When I look at what is using the battery in the settings menu, I've noticed the music app is never displayed (same thing with Netflix) but it seems to be using a decent chunk of memory.
Wondering if this is the root of my battery problems, it does seem to have gotten worse ever since I got the music beta invite..

Noticing battery drain also. Ill monitor it and get back to you. (Nexus S).

to k_nivesout: i have been narrowing down the list of possible culprits since first posting this. In my case it seems to be either music beta by google, cell standby or a partial wakelock caused by maps. I turned off my location which caused a drastic increase in the battery life but still did not give me the life I had with my last incredible. Cell standby was showing significant battery use most likely do to my lack of signal in my office where i work this summer. On the weekends I notice slightly better battery life in my house where i have full reception. This being said, music beta by google is the only thing that has actually changed since my last incredible. I am contemplating uninstalling it....

That's a good observation! Well my phone is at 99% battery now, and I just uninstalled Music Beta. Will see if my battery life increased, because I too have seen an decrease in battery as of late.

Thanks for the replies everyone, I'm definitely curious to see if music beta is indeed what's causing the battery drain. I might have to uninstall it for a day or two and see if things improve. I'm assuming it would be easy to redownload and sync everything, I'd be interested in your guys' experience.

same terrible battery life on my D1 after installing the google music app....my library is also still uploading from my home computer, not sure if that makes a difference or not. one difference, however, is that in my battery stats, google music was at the top of the list. not sure why its not showing for you guys, but i uninstalled and everything seems back to normal now.
i will try re-installing it once my library uploads completely and see if that makes the difference....hopefully so!

Unfortunately I didn't really notice things get better even after my library was uploaded. Good info though, were you looking at battery usage from the settings menu?

With google music you could turn off auto sync. Especially when you are uploading from your computer.

Here are my tweaks. Right now I'm at 7 Hours 46 Minutes with 66% Battery life. Couple hours of listening and downloading podcasts/audiobooks/music, some web browsing, app downloading and uninstalling.
Turn off Google Music Auto Sync
Turn off Google Book Sync
Check Weather Apps, stop any auto sync or location tracking
Turn softkey light off whenever possible (CM7 settings)
Screen time out 30 seconds (15 would be even better)
Juice Defender Ultimate (Controls Data/Syncing, huge difference for me)
No DSP Manager Tweaks
Remove any excess apps/ games
Ad Free Android (blocks ad downloads)
Incredikernal, ondemand governor
Turn off Bluetooth
Turn off GPS
I just got this phone a few days ago, and my battery life went from 60 to 30 in 20minutes while it was syncing for the first time. Its working much better now! I even considered extended batteries, but I don't think I'll need them anymore.

I have the Vibrant and am seeing massive battery drain all of a sudden. I too have recently installed Google Music. Music upload from my PC is finished. Hasn't made any difference to the battery. I don't see any option to turn off Auto Sync in the Android app and in the settings. Where is this option?

Accounts and sync>Google account
Music sync will be in there.

Strangely, I don't see any battery drain today. I haven't been using my phone. I just wanted to monitor it (using Android Assistant) to see what app was using the most battery. Yesterday, without any use, the battery completely ran down. Today, it's down 13% since morning. And I have been gradually adding background processing, GPS etc.

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.

[Q] Juice Defender: does it work?

Hi, Ive been reading a lot about battery saving apps that I started to get curious as to whether these apps really work.
I installed JD out of curiosity and I have to say that all it doea is disable automatically your phone connections to help you save power. Things that you can actually do manually. Like turning off wifi and mobile network. If im not mistaken you can disable mobile network under your phone's settings.
So my question is, if you can do it manually, what is the point of apps like juice defender? It eats up ram and runs as a background process which in my opinion does more bad than good to your battery unless your the i dont know how to disable connections manually in my phone kind of guy.
Somebody please enlighten me. Thanks.

I have used it for a long times. Since I used Xperia PLAY.
I think this program is good. Yes, if you can manually do it. But the feature I like the most is Screen. It can change CPU ghz according to your screen on / off.
It saves my battery a lot.
Press THANKS if you agree with me.

I am a long time user of jd but these days the only feature i use regularly is to disable data overnight.
Sent from my LT26i using xda app-developers app

- Airplane mode over night
- automatic wireless connection with "location" feature (if near a known wireless network it starts the wireless and connects, if not near it directly starts 3G)
- I do not have to mess with on/off wireless/3G
- automatically syncs every hour, so I have to do nothing but still get my mails
- with rooted phone underclock on screen off
- bluetooth off after 5 mins without connected bluetooth device
etc....
It is NOT for you if you want to have online connection all the time. And it is not for you if you don't mind to do all the things manually it does for you.
And in my opinion only the full version really helps, the free version does not much...
I think it's a great app! :good:

If you just need to auto toggle data, check out 3GBattery too.
https://play.google.com/store/apps/...wyLDEsImNvbS5teXN0aXF1ZS50aHJlZWdiYXR0ZXJ5Il0.

basically, there are 2 main things that drain our devices: 1) 3g/2g and 2) display brightness. I've been using JD since ever, and the difference is awesome with and without. Even the free version is enough to save some batt, in the Agressive mode (connects every 30min).
Besides JD, I am using Greenify. Which needs root to work and does a beautiful job with background apps like Facebook, GMaps etc.

works on both my devices :good:

Personally I think this app is useless.
As OP has said, you can just set up those things manually.
This app just eats RAMs and use your battery up more.

Best battery saver apps for nexus 4

Hi All,
I would like to invite your suggestions on best battery saving apps that you are using and how much difference does it make. Is it worth paying for apps juice defender ultimate or so http://forum.xda-developers.com/images/icons/advanced/battery_full.png
I am on stock (rooted) 4.2.1 and stock rom.
Thanks!

Best battery saver is your self. These apps don't work any better than you doing the things it does manually. If its using resources which they all do to "save" you battery... Its not really saving you battery.. But in fact using it.
Some tips I suggest:
Turn sync off in everything. Go to data usage hit the menu button and uncheck auto sync data. Also you will want to open apps that have notifications and make sure they aren't syncing either.
Remove maps if you don't use it or disable it at the very least this will keep it from polling your location and wake locking the device.
Keep your running apps to a minimum and force stop any unnecessary apps.
Turn off Google backup services. Sometimes this will be pulling and pushing data wake locking the device and using battery. I've never found it necessary especially since I use TiBu anyways for my apps to restore. It never saves my WiFi password either.

This isn't particularly good advice in my opinion. Are there apps that do use battery power when you don't force close them? Yes, sure, but many don't. And those which do without a good reason.. try to find a replacement.
Force closing apps all the time especially on a device with lots of ram will mean that your device has to restart the app completely if you open it again, which takes time and energy.
edit:
Also, turning off sync doesn't really help that much if you still use your apps often but instead refresh manually with the screen on, I'd expect. Of course everyone can decide for themselves, but one of the reasons I own a smartphone is because it can notify of an incoming email or something without me having to go to gmail.com manually. It all very much depends on what you want from your phone and how much you are willing to compromise. Using an App like Lux for example could also save you some battery depending on how bright you need your screen to be etc. There are so many variables to this.

Best battery saver is to not run crappy battery hogging apps like juice defender.
Turn on auto brightness, check your apps and make sure you are not syncing very often unless you need it. For most apps you can turn off auto sync and probably sync manually. I just turn on auto sync for handful of important apps which I open regularly.

Manually turn down screen brightness, don't leave the Wifi or bluetooth on when you're not connected, make sure apps you install aren't keeping the phone awake. Not much else actually works in the real world.

I get two and a half days from my Nexus 4 battery, I can thank Juice Defender Ultimate for a large part of that.
I could do all the tricks that Juice Defender does manually, but it would be a PITA and I'm sure I'd forget some of those tricks.
Better to pay a few quid, take a little time to set up Juice Defender, then sit back and enjoy your doubled battery life.

the best part of Juice Defender was turning off Wifi when not at home.. if you like this feature, search the playstore for 'Y5 Battery Saver'. It does the same thing, is simple and free..
Note: dont backup and restore it in titanium though. If you rebuild, install from the playstore. I have found it doesn't work right if restored

IMO if all you want is bt/wifi to toggle when you aren't home spend $5 on a few nfc stickers and stick one by your front door. You could also go with tasker.
As for battery life, francos kernel is giving me 2 days of battery (far more than I need) with wifi/bt on, whatever apps need to sync do so and I have brightness set to auto.

I found juice defender good for phones that are bloated with crapware and not rooted. It hurt battery life when i used it for phones with custom roms and kernels.

After I turned 'Google location' and NFC off, this thing can easily last the day with average use. Before that it was just draining like crazy.

I've had juice defender ultimate since my Nexus S days. I wouldn't be without it as I can't get my battery to last a full day without it. When it's fully configured correctly, it works fantastic. I especially like that I can configure wifi to turn on and off automatically in areas where I have a saved wifi. I can decide the interval I choose for syncing data, and there are many other features. I'm not going to be manually turning on and off functions all the time, all that does is create more screen on time and is a waste of my time.
Bottom line, for me juice defender ultimate works because I spent time configuring it properly for my usage.

1.5 hrs screen on, 1.5hrs on call...I got close to 6hrs screen on when I did a drain test.
And no, I wasn't getting 2 days out of the phone stock with the same usage, it was more like 12-18hrs.

I tried using Juice Defender on a different phone and all it did was make the phone buggy with problems with wifi connectivity and other minor irritations and I could never configure it in such a way that didn't give me problems.
Are you having trouble making it through the day on one charge? I don't think I could use my N4 that much if I tried, I sat in a doctor's office the other day for 2.5 hours listening to Pandora on a bluetooth headset while reading a book with the screen on and still made it until I turned in for the night. Perhaps it is the Trinity kernel or custom ROM I am running, I never ran my phone stock so I don't have anything to compare with. I guess some of you want to go longer than 24 hours but it would be a really bizarre situation for me to need to do that.

So I tried juice defender ultimate and it did significantly increased my battery life. I am now getting about 30 hours or more with my regular usage. Even right now I have 63% remaining battery with 1 hour screen time and 17 hours total run time, see screenshot for usage.

Battery Consumption Too High

Hello Guys and Gals,
Its been awhile since i have been on here. But i have been very satisfied with my Note4. However. It had come to a point that carrying 4 batteries with me to make it through the day was too much.
Here i am . Finally upgraded to the 8+ and overall. I am very dissapointed.
So. i would like some input on what changes you have done, as well as apps running, how much you use the device, your daily connections. and so on.
i have:
Bluetooth always on, connected to my Gear S2
Location services always on
I am a big social media junky, on FB, and IG, not too much of Snapchat.
I use Line to talk to my group that i game with
I play Transformers Earth Wars, about 15 minutes at a time a few times a day.
Do not use bixby
Screen display is set at Amoled Cinema, HD resolution, auto brightness is turned off stays between 30-60%
Very Rarely use WiFi
Google apps do not auto Update
USB Debugging
3 gmail accounts linked, sync is off
Anything else just ask,
So after my 8hr shift of work, my phone is at about 40%, my Note4 on would almost make the whole day, i would get to about 20%, then i would switch batteries.
I am not happy with the battery. Just seems like for no reason it is draining.
Comment below, let me know your setting, impressions, and so on.......... Maybe im doing something wrong and dont realize it.

Well your first problem is all the social media apps, pretty much all of them just destroy battery life. When your not using those apps I would put them to sleep.
You need to monitor which apps are draining the battery. You can do this through the stock device mait. app. Once you find out which apps are causing the drain we can go from there.
I use standard mode, screen on WQHD, sync always on, all data no wifi, screen at 50 % or higher. No social media apps, I use the browser for those.
Here's some screen shots of battery life, this is and average battery cycle, I have reached over 9hrs of Screen on time (SOT) and 1.5 days in previous cycles.

Believe it or not sometimes that consumes more battery life having to open the app every time vs just letting it run in the background. Probably not true with social media apps but it's worth a try. You may also want to try a package disabler app from the play store to disable apps you don't use that run in the background. I use BK package disabler.
