[Q] Newly rooted NC having battery issues...

Got a NC for xmas and rooted it and installed cm7.1 and everything seems to be working well except the battery. I went under battery use and i see that Display is eating about 60% of my battery! I turned brightness down to 25%-ish and i have also turned off everything i am not using but the problem still persists. I have seen people saying i need to do some kind of battery calibration but i do not know how to do this. If someone can help me get this issue resolved it would be greatly appreciated.

Unfortunately, you can only do so much about screen battery consumption. Turn brightness down as far as is comfortable, but personally, I don't want to give up the vibrant display. I find 25% is usually adequate indoors. With my screen ON, it consumes roughly 10% per hour of use, which equates to 8-10 hours of use -- not bad. With the screen OFF, it sips less than 1% per hour, and often less than that over a few hours.
Keep in mind, you WANT screen battery consumption to be the largest value. That means it's nice and idle when you're not using it. If something else is using a significant amount of battery, that may be something you can do something about.
As to calibration, I do find that Android battery gauges often are incorrect until you let the battery completely discharge from a full charge once. Then it's calibrated correctly. Of course, that's not recommended for battery health, so don't do it compulsively. I had a device that showed 1% battery remaining for 3 hours while I played MP3 audio.

I wish i was getting 10% an hour, im getting roughly 20% I now have another issue that i did not have this morning, i can not connect to my computer via USB. Is there a setting i might have turned off in my fit to increase battery life?

@Lsjreadingpa Renaming /system/app/phone.apk to phone.bak is a commonly undertaken act that can significantly lower battery usage. Also, you can turn off Account Sync when not using it actively, as it increases battery drain when you are not actively using the NC.
As far as the USB is concerned, make sure you have USB debugging checked in the settings menu.

How do i rename it? Also a bit of an update, i have turned off syncing as well as alot of the other options and i am losing 5%/20min

Last night I cleared cache and battery stats and let the battery die and then charged it to full this morning. Like I said above I turned off syncing and gps as well as removing beautiful Widgets. I just don't know what else to do. I'm attatching two screenshots showing my battery use in the last hour.

You can use Spare Parts to check what's consuming battery if your DOMAIN supports it.

Anyone able to help?

Are you concerned about battery consumption while you're using it? If so, then your brightness and the applications you're running are going to determine your battery life.
If it's battery consumption while idle (screen off) that you're concerned about, then do you have any widgets that do network access? I found that my battery life dramatically improved when I was no longer using the Twitter widget.
In Spare Parts you can go to Battery History, then check 'Partial Wake Usage'... this can help you figure out if there's an application that's preventing the device from going to sleep.

I would recommend trying a newer nightly or the Mirage/Kang build found in the Android Dev sub-forum here. I forget when they were added, but there were a few big improvements to CM7 a while ago to help with battery life.

Battery consumption while using it is kinda of scary because it drops like a brick. While sleeping, which i don't think it was doing, seemed to get better after i removed beautiful widgets. How different is the Kang build?

The Kang build has an updated kernel and other updates since the last CM7 nightly. It's supposed to fix an SOD issue. I've been running it for a while and am very happy with the battery life.
Like others have said, battery life while using it would most likely be helped by adjusting the display brightness, kernel settings and/or stopping "rogue" apps. You can see the kernel settings by going into the Settings Menu, then Cyanogenmod Settings then Performance. I use the InteractiveX governor (I believe "Performance" is the one that keeps the CPU ramped up constantly) with the highest overclock.

Battery Life Help! BatteryStats LogCat Help Please!

Guys, I am getting terrible battery life on the newest BajaRom. I was getting decent battery life but somehow everything changed. I want to note that I cannot access the Media Battery Drain Fix in the BajaROM settings as it crashes EVERYTIME i open it. I have tried everything to install something that will fix media battery drain but I am unsure if this is what is really causing my battery drain. Please any help would greatly be appreciated!

Wakelock Detector and Greenify... are ur best friends on the Note 3.
Turnoff wifi,bluetooth,gps,etc when not in use. Set CPU to on demand. I always have power saver on unless I want to run a game... doesn't seem to effect anything else.
There are a ton of tips for Note 3 battery life...just search here...
I also use LUX for screen brightness, that made a big difference also. Change you wallpapers to darker colors... mine are some sort of black background...
I can make through the day with reasonable usage on Hyperdrive RLS8 and still have battery left...
Haven't tried BajaROM yet...

Thank you for your response. I have greenify'd most of my daily apps and I use wake lock detector and still cant find out the culprit here. It says that my SCREEN is taking up 30% of my battery life after just 2 hours unplugged and minimal use and I'm down to 82%. Can my phone just be inherently defective????
This DOESNT feel right. I NEVER had any complaints of battery with my NOTE 2

Check your data usage. I had the similar situation, saw nothing in the battery usage area....but then checked data usage. I had over 2 Gigs of data usage from EMAIL in only 2 weeks! I had been using the std email app...and get maybe 10 emails a day. Obviously something goofy going on in the sync. Yet battery usage showed next to nothing for the sync process or email app.
I removed my accounts from the email package, froze the email package and installed AquaMail and my battery usage cut by at least half....my data use flatlined.
Obviously it takes power to use the radio for a Gig a week of data....but that does NOT seem to show in battery usage.
so check your data usage...see if email is way out in front. That may be your problem.

I had the same issue with battery life after I flashed to and of the KK roms. My problem was Greenify, and I don't know why. Removing it didn't solve my problem so I'd restart from the beginning. My drain is less than 1% per hour idle without it and almost 10% per hour running all the same apps with greenify in different settings. Jasmine ROM just drained for me all the time.
*first post, be nice. I only joined because of all the trouble I went through to get my battery life back.

Horrible Battery Life, I've tried everything

I can't figure out what's going on with my T-Mo Note 4. I have about a hard limit of 2-2.5 hours of SoT (auto brightness, all in doors) before hitting critical battery levels. I've tried numerous factory resets, including odin restores. Then I tried all the greenifiy/amplify options but that didn't make any difference. I am currently only running a bare minimum subset of apps to troubleshoot the issue. The wakelocks aren't bad, but not great either. Over night I'll lose about 10% battery. But actual screen usage is what murders it. I even bought a set of new batteries thinking mine was a dud, but my usage on those is identical. I'm not even doing demanding stuff on it, just light web browsing, and non 3D type apps.
Currently I'm running the X-Note 3 ROM with the latest AEL kernel, battery life is the same on it.

Settings > Wifi > Advanced > uncheck 'Always allow scanning' and 'Network notifications'

let us see a screenshots of user apps installed and a screenshot of battery history under settings>power saving
some apps\widget are known to eat battery
also, what apps do you use mostly when screen is on

How's your signal? From what it sounds you may have a bad signal which is causing your phone to lose battery life. My phone drains pretty bad at work since I have a bad signal. I started turning off my data and battery life is better now.

I'll get some screen shots tonight, just popped a fresh battery in. My signal is all green on the graph from when I have done previous troubleshooting though.

should use stock. no stock ROMs have all sorts of weirdness.

The other day I had Deezer music app keeping my phone awake constantly. Just now i've checked battery and google services framework has kept my phone awake 4.5 hours since I unplugged it.
Very strange goings on on this phone. Still getting 5-6 hours or so screen time and a full day, but things like this surely have an impact.

Here's my 2 cents:
In the battery usage page under settings, tap the graph. If you are using an SD card AND your phone is awake while the screen is off (and you aren't playing music or something), then do this:
Back up any important data from your external SD card to a computer (movies, music, photos, etc).
Go to settings/storage and format your external sd.
Then copy all your files back.
This may fix the Awake issue. MAY.
My phone was staying awake 100% of the time with only about 2hrs of SOT. Battery was draining fast because the phone was never going into deep sleep. I noticed that when I removed my external sd, my phone suddenly began to sleep. So I did what I said (which was a trick from my S2 days on ICS) and it then made my phone sleep properly.

Hi , Sorry to hear the battery issue you have been having. I have been experiencing the same issues as well, as I only could manage a miserable 2 hrs SOT from the almighty note 4. I was fed up and looked into it the issue and adjusted some settings and stopped some services and now I have over 4hr. SOT . I have changed the following :
Disabled the location services
Disabled all the bloatware esp some of the Google services i.e.. Google Music, Google Plus & Google Play Movies (and any other Google services that are not required)
Bluetooth Off
Screen is at roughly 40% brightness ( I do not use auto brightness as it sometimes max's the brightness for no reason)
Try the above and you may have a phone that works as its supposed to.

As with the SD card I think that is your culprit. Look in the battery stats for "media server" or "samsungindex". These are processes that search for files in the SD card and cache them. So in order to fix that google has the answer but the basic principle is that you have to delete that corrupt file which these processes are searching for... hence why google lost faith in the sd card and why iphones don't have them coz of these problems..
Turn off sync and mobile data some apps in the background keep on syncing hence the drain combined with your mobile data makes it like bacon and eggs, if all else fails you may have a faulty phone, have it replaced. Good luck!

Battery drain

So I unplugged the phone in the middle of the night with 100% charge and woke up with 75% battery the phone is Stock can anyone tell me what is draining my battery.

Wifi and gps?!
When you sleep turn off everything. Me just drop like 3%

I had WiFi set to always on, just put it back to always on only for the charger, and GPS on high accuracy to battery savings.

Hard to know, my Style seems to have similar idle battery drain issues.
It generally shows high google play services usage so may be a bug on location services or something like that.
I wouldnt recommend turning wifi off though. Maybe try playing around with location settings though.. I havent really looked into it myself yet. Kind of hoping it would fix itself with a play services background update.. might be wishful thinking.

Yeah, I just switched from the nexus 6 and it also has Google play services that was high on battery usage.

Get better battery stats and find out what wakelocks are causing your drain. I lose only 1% per hour or less after tweaking.
Bangin' on my unlocked/rooted
Moto X Pure

your have no idea.. try factory reset.

My battery experience has been very positive on the MXPE. My usage on idle is less than 1%/hour. After a whole day of normal use yesterday, including occasional phone calls, bluetooth, low-power location on, and about an hour reading on it, the MXPE averaged 1.9%/hour. This is the best battery life I've ever had on a phone.
The biggest battery drains are the WiFi network notification, WiFi scanning always available, both under the Advance WiFi settings, WiFi always left on, using high accuracy GPS all the time, and the myriad of push notifications in apps these days - gmail, yahoo mail, facebook, google+, twitter, google settings, etc. I disable all push notifications in all apps except my work email, and that's on an hourly polling rate, and weather bug, which updates every 30 minutes. It takes a while to drill down through all the various app settings, but the result is well worth it in terms of battery life. Of course, it you want constant push notifications and high accuracy GPS 24/7, then you get what you get.

Anyone else has any tips?

If you're rooted an app like LeanDroid can really help manage connections when idle.

So I disabled WiFi while phone sleeps and the wakelocks are gone also wiped cache in recovery.

Another tip. GPS to device only. And turn off the Google app location BS. The Google stuff drains excessively and device only actually drains less than battery saver lol. Battery saver seems to keep GPS on all the time while device only seems to to only activate GPS when an app pulls it.
P.S. disable the discover card app from polling location cause it does so way to often. Otherwise... Good luck.

Overnight battery drain

I have a problem that I noticed some people are experiencing. Overnight idle the phone drains like 25% with wifi off and on battery saver. Is there a known cause for this? My Honor 8 is brand new. Help!

After I wake up it's normal again (I turn WiFi on and use phone normally) -
I will try and leave WiFi on during the night today to see if it makes any difference.

Fyi, since I woke up and turned wifi on, the battery has only went down by 1%! Something is not right. How can it drain so much without using it and almost none when I actually use it.
Screenshot from today (from 1pm till 7pm, only lost 2%)

Which hardware and firmware version are you using?
Do you have cellular data connected when WiFi is off?
Does the battery graph show constant system awake time during these periods of high drain?

Hi. I'm using FRD-L09 and EMUI 5, build FRD-L09C432B381.
No wifi, no mobile data turned on. All apps closed.
Yesterday I left it at ultra power save when it was at 12%, after I woke up (around 6 hours). it was off. Don't think that's normal either.

Sometimes I have the same problem. Overnight phone drops 25% of the battery.
What I found useful is to turn off Wifi+, Link+ and in GPS location (3 dots -> Search settings -> turn off Searching for Wifi and Bluetooth). In fact that will stops searching for Wifi, while Wifi is toogled off.
It might help you, I think this is Android 7 issue, since most people complains about heavy battery drain when not using the phone. Noone complained when using Android 6.

This isn't normal, but at the same time it is... I don't think any one person has figured out the real reason why, but many of us have had similar battery drain for seemingly no reason. I simply backed up my data and factory reset the phone and haven't had an issue since. Others haven't been so lucky.
Can you take a screen shot of your battery graph so we can see if your system is awake during the drain?

I have update B381 and u have this problem with battery drain for my is very bad battery life update B360 was good for battery life.

I found the high Idle battery usage some what related to the phone keep search for upgrade and the process "android OS" was consuming around 50% all the time.
After set these two setting, it fixed the battery drain and "android OS" only use around 20%. Now it remains 100% battery for 10 hours standby.
1) Setting->System update ->(three dots)->Update Settings->Wifi auto download (Disable)
2) Setting->Battery->(Setting icon on top right)->keep wifi on when sleeping->Never

I did as everyone suggested and turned off auto WiFi and bluetooth search and auto WiFi download of the system updates. If I turn off keep WiFi on during sleep, I don't get any notifications from messaging apps, so I won't do that. I've also only left Messenger, Viber and Whatsapp in the whitelist of programs that will be closed when screen is locked.
Here is the most recent screenshot of the battery usage.

Try factory reset and wipe cache. Screenshot tells us that your phone is awake when you are not using it.

Okay, I'll try later tonight and reply tomorrow if anything's changed.
p.s. Any good full backup apps?

Just use the backup tool that was loaded on the phone. It works nearly perfectly to backup all your texts, call log, apps, settings, etc.

Looks like it tried to sleep when you went to bed last night, but something woke it up early in the morning and it never went back to sleep. Find out what that was and you may solve your problem.

If you have data, you still get notifications.

As a test, I created a Magisk module that freezes all of Huawei's system power management apps and superfluous services. I just loaded it today, so it'll be a few days before I can provide feedback on if it improves battery life.

I backed it all up and am wiping it tonight but I was thinking. Perhaps it's not a good idea to restore the data yet? Maybe I should try a night with stock settings/apps to see if that makes a difference, then restore all and see if there's any difference.

Honestly, I wouldn't expect that experiment to provide you with any useful info. You will naturally see more battery drain once you have your apps and services running because more will be happening in the background. Reinstall everything and use your device normally to get the most accurate comparison to your previous battery life.

Factory reset I know how to do, but how to give the wipe cache?

IIRC, the cache should be wiped automatically when you Factory Reset.

I like to do it manually. Turn off the phone. Hold Vol + and power button.

I wonder how the battery drain overnight will be with the new custom Roms which are out.
