Battery drain on JB!

Is anyone else having big battery drain since updating to JB? I used to get 2 full days now i can't get 16 hours my phone is staying awake. I'm stock unrooted using juice defender plus. Thanks in advance.

I don't get as much battery I get about 8-14 hrs with 2-4 screen in time I use to get 10-20 hr with 3-4 hr screen on time. I hope they realise a update to help fix the issue seems like quite a few are having.

Yes. I suspect you're probably having the same problem as me. Ever since upgrading to JellyBean, the battery is horrible. Checked BetterBatteryStats, and it's because of msm_otg, it's constantly hitting the device with kernel wakelocks. If I look at CPU states, my phone has been in 384 MHz for 97% of the time, deep sleep 0% of the time. Since it's not sleeping, the battery is draining much faster.
It has something to do with USB on-the-go, but I can't figure it out.

I am having opposite experience. I am getting incredible(to me) battery life. Fully charge yesterday at 430pm and this morning after a bit of texting and calls, battery is at 80%. Pretty good and should be able to get at minimum 1.5 days usage out of it at current rate.

Also, disable Google Now. That's known to be a huge batt drainer.

Sorry for the noob question but how do you disable Google now, never used it so don't know which one it is. Thanks in advance.

This still didn't fix my battery problem. But you'd go to apps -> Google -> Settings -> Google Now. Press the on/off switch at the top right.

Thanks, we'll see how it goes from here.

Did notice my battery was draining more before JB. Once I downloaded JB my battery seemed to drain worse. Finally figured out it was Nova launcher, so switched back to TW and battery is back to normal, with google now on, mainly just get traffic and weather for now.

I apologize for posting in the wrong section. The battery drain continues even after disabling Google Now uninstalling Facebook, pandora and other apps and turning off gps, bluetooth. Andriod OS is staying awake and killing the battery. In data usage delete apps is running in the background at 43 mb? Anyone else?

For me it started with LI3 then into JB.
I noticed Media was at the top of my list when i checked what apps were using battery.
So i ended up disabling the com.sec.android.providers.downloads and so far i think this has helped get my device back to normal battery life..

I don't like any apps that are supposed to save your battery. they usually contribute to battery drain. get better battery stats and see what's causing wakelocks. it's probably location services related to google now. when you don't need it, turn off gps AND location services

Here's a possible problem http://rootzwiki.com/topic/21871-ro...y-build-discussion/page__st__2690#entry750372
I would be more concerned with partial wakelocks first, then kernel wakelocks second

enable restrictions and make sure your wifi isn't when not needed same with your Data. if you don't have 4g, turn on only CDMA data. went from 50% every 4 hours just to 15%

Facebook has always been a huge battery drain. Especially now that messenger is integrated into it. Friendcaster Pro is much better anyway

Exact same issue for me. I will try this.

I have had severe battery drain for a few days now. I disabled google now yesterday and that didn't change anything. My phone was constantly warm. Today, I turned airplane mode on and the battery still drained. It got down to 58%. I read somewhere in this forum that the google maps update was causing some battery drain so I uninstalled the update at 58% battery life. Three hours later I had 57% battery life. So, for now I can only assume that it was google maps that was consuming my battery. I will have to try updating maps again to make this a more concrete assumption.

[Q] how to improve batterylife without any apps?

Hello,
as everyone im really happy with my GN2.. everyone says that the battery just drops 1% percent everyhoure..?? thats not the case with me.. it drops 10%-15%.. is there any settings you have done?? its still on stock rom didnt rooted YET
I didnt install/download any virus or fool apps from playstore (Ive read many threads but they were all the one who downloaded just random apps from playstore and that caused for battery drain..)
waiting for your answers..
ps: everyone is welcome with his settings.

Wow. 1% every hour? I won't be bothered to change my phone if that happens :silly:
A normal Galaxy Note 2 has a 1% drain every 10-20 minutes of screen-on time.
The screen-off time of the Galaxy Note 2 is indefinite. Depends on what you have on

haha when i first saw that i thought wOott 1% / hour impossible.. but when more persons said the same i thought "hmm maybe I'm wrong".. so they are ****ting maybe D
but tbh do u have everything on like google? google now etc??
now u have said that im pretty released from ma sorrow

No, I don't actually. I do not know what the screen-on time from persons' who have sync on.
I usually get 7++ or 8 hours screen-on time, from my usage.
That's with wifi, games, phone calls, messaging.

With this kind of device, you won't need Juice Defender

I leave everything on: data, wifi, autosync, nfc, autobrightness, everything.
I still get a full day with 5-6 screen time.
Just charge every night. No point disabling data and sync and everything. Makes it pointless to have a smartphone

Wow. Wifi and data on? You must have super internet, man! Coolness!

I've left the office just about an hour ago... Charge was 100% and I have opened video (auto-play next=ON) playlist. Trip to home has took about 40 mins and every single second device has played videos, non stop.. No app, nothing special. When I arrived, the charge was 99%
It's probably has its very own battery optimizing systems inside which is clearly avoiding energy leaks.
I guess, I don't need anything for now to improve charge durability... Just fyi about my little test~

Hello again,
Actually our phones need nothing for better pattery durability. But if you wonder your battery specifications, i would like to recommend "Battery HD Pro" from google play market. It supports Turkish language and more.
Good luck.

The gnote2 loses ~10% an hour on WiFi and ~15% on mobile data. You can get more than 10h reading books with white text on black background. And videos on internal/external storage can get you more than 10h display depending on the video. I generally get about 10h display in WiFi and 6-7h on a workday where I use mobile data and I haven't flashed a custom kernel yet. Too much extraneous junk with the current kernels. Just looking for one that allows custom voltages on various things, mainly CPU and GPU.
Sent from my GT-N7100

I don't use any power saving apps. I have everything turned on and syncing 3 email accounts. I lose 1% overnight and rarely lose a percentage when the screen is off. What did I do? Just turned off google now and the 3 tick marks under GPS setting. Good luck!

Just to share my battery drain, i play games almost 4 hours a day, rest of the time texting, maybe at most 2 hours of screen-off a day, my phone is 40% when it says 8 hours on, dunno what all you have, i have wifi, data sync, auto brightness, and well gaming, the game though are bike race and minecraft, but when with sometihng heavier like modern combat you can expect 6 hous and its 20% just sharing im stock rooted..

I agree with @akdenizx
Wanam's tips is so succesfully for battery life. I use my phone with this advice. I am happy. My phone is charged every 1.5 day by me
I want to one tip for wanam's tips.
Wi-fi sleep policy must set never.

Try using white text on true black background. Saves a lot of power on Amoled displays. The inverted colour option on the stock browser gave about 13 hours of screen time compared to the normal 7 hours

FInd 7a - battery drain and solution thread

Hi
I have received the Find 7a . Tho only issue I have with that is the huge battery drain when off ( even with data and wifi off )
Therefore I want to create a thread where we can share the solutions for this battery drain issue.
PS: I am running ColorOS 2.0 beta
cheers

I dont understand why people keep complaining about the battery. I use my 7a a lot and the battery lasts me just fine and I have Wi-Fi and GPS always on.

It's a known issue, I'm actually in a pilot group with a product manager and developer using a new firmware based on 1.2 that seems to help.
In the meantime, change the lockscreen from Colorlock as that has been known to hold a wakelock and disable Google's location services.
After I did that on 1.2 or 2.0 beta my drain shot down to .5%/hr.

I too am part of said pilot group that Sean mentioned and can confirm that a more battery saving firmware is in the works.
Give oppo some time to work the issue out, it's starting to look better.

Freezing applications/disabling them is basically the same as removing them, except that they still take up space on the system. You can freeze applications using Titanium Backup as you said and if you have root of course. If you want to completely remove the applications you should get a file explorer that can request root permissions, then look for the applications you want to remove, these can usually be found in "/system/app/" or "/system/priv-app/". You can also remove them using adb, this is a little more complicated though, if you want to do it this way I'd recommend you to Google it. Be careful when removing files from the system though, as you may run into some weird situations, you can always make a backup of course. (when restoring back-upped files, remember to set the correct permissions)

enabling google location services do not have impact on standby battery drain, seems changing the lock screen and freezing default launcher (I use Nova) helped
cheers

I'm on 2.0 beta, changing that to Revolving lock and disabling Google's location services (gimps the phone a bit sure but easy to enable and gps is still fine) and my drain is down to .6%/hr. Not too shabby, and will be testing tonight with location back on.

have been using the find 7a for nearly a week now. all i can say is...be patient, people! the first 2 days i had it, the battery drain is unbearable(8~12hr use and it's gone), but after 3~4 full cycle charged (start charging when below 10% then fully charged using 'battery doctor'), from the 4th day, the battery is amazing, easily get past 24 hours of use with data and wifi always on, screen on time 3 hours+ no problem. my current used time: 34 hr 26 m, with screen on 2 hr 7m, battery still 33%. Google location service is on all the time, Google now is off all the time. GPS off most of the time. running color OS 2.0 beta.
so be patient and charge your battery for few full cycles.
i hope this may help you guys.

Even Oppo has publicly stated the massive battery drain is a known issue affecting all Find 7a phones sold to date so I'm thinking denying there is an issue is a bit silly at this point. Also 2 hours screen time with 33% remaining is a terrible performance that sits at approximately half of what this phones current competition is offering.
Having has this from day one I would also point out that one of the problems associated with this is the inconsistency. I normally will see around 15 percent drain overnight but occasionally its as little as 5 or as high as 70. The problematic part comes in when you figure I've spent most nights testing some new scheme to see if I've made any improvements to the standy life.
Nor do I think its a good idea to accept excuses. On my N5 I never turned anything off, bluetooth, wifi, google now, location, etc. All on all the time and never had a problem getting 4 hours of screen time and never used more than 5% over night. That would of course make it nothing special since I haven't owned a phone since back somewhere around the sgs2 that couldn't do the same thing and there have been lots of phones between here and there. You shouldn't have to turn the phones features off to get the phone to work, being forced to means you are getting a sub industry standard experience. Calling it anything else is a lie.

Rapid Battery Drain - How can I improve?

My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

Could well be your brightness level? Are you using autobrightness or is it on a fixed level (I hope its not fixed at 100%!)
If you use autobrightness try using an app like LUX auto brightness instead.

My guess is a corrupted media file somewhere which is causing your media server to prevent the phone from going into deep sleep. When you go to settings , battery, is media the no 1 juice sucker?

I did try that, but it didn't work and the phone was a bit laggy. Why would android system take up 15% of whatever the battery uses? I'm getting so frustrated, I might do a factory reset.

How long has that screen been on for?

A shot in the dark:
Do you skype? Skype was draining the battery down in the Nexus 7 2013 even when you were not using it. I disabled it and the battery improved greatly.
Another option:
It sounds to me that there's an app that is draining the battery down a whole lot. I would try to isolate that app (by deleting each one you downloaded one at a time) until you have found it.

I don't have skype, but I like your idea - I've gotten rid of almost all the bloatware stuff. What I think I'll do now is charge it to max. DO a factory reset and not allow Google to start downloading all my apps again.
Funny thing though - when I charged it last night and unplugged it for 3 hours it only dropped a couple of percent. It started dying rapidly after I opened up a few other apps.
What I'll do now is charge do a factory reset, then switch it off, then charge to max before turning it on again. When I first got it, it turned on as soon as I plugged it in. did the same happen for everyone?

What you might want to do is download Greenify on the play store. This will tell you what apps are running in the background and then it will turn them off (hibernate).

Make sure that you leave the battery charging for about 10-15 minutes more after your cradle light turns green. Sometimes the battery isn't fully charged despite the cradle light turning green. 30 minutes on a game shouldn't be using that much battery consumption.
I usually get about 10-12 hours or more on each of my batteries ( video calling, chatting, games and my 4g is turned on 90% of the time
Try this from Google Play

You can read their reviews and install the app but don't download too many battery monitor apps Keep us posted after a few days of monitoring Good luck :good:

Battery Drain

Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.

My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

I cannot disable it since it is comprised of multiple apps. You can see it in the pics on my last post.
