[Q] Bad battery life

I'm running AOKP 20 and Franco kernel but seem to be getting really bad battery life. I see folks claiming 1% battery loss over 8-9 hours of sleep. Mine loses 12-15% while I sleep and that is with WIFI on.
I'm not real familiar with the Better Battery Stats or Battery Monitor Widget. Can I use one of those to find out what is killing my battery life?
Does anyone know of something that might be causing this or how I can find out what it is?

Rogue app? Wich Franco are you using?

I tried 14.4 but went back to 13.1 hoping things would improve. Same on both.

Better Battery Stats' ugly interface really does mask what I feel is a great app. In your case, assuming you have it installed, change the top box in the app to Kernel Wakelocks and Partial Wakelocks and see what is preventing your phone from sleeping (post the screenshots of the two pages if they mean nothing to you).
I've also found CPU Spy to be an easier to understand quick overview of what's going on with my device. It'll list out the various clock speeds my kernel has and how much time was spent in each. If you notice "deep sleep" isn't the biggest bar, you likely have something going on.

Yup, yup. I was going to suggest CPUSpy, it's a decent little app. My phone will spend ~60-70% of the time in deep sleep over a nine hour or so period with WiFi on.

It looks like my phone is going into deep sleep and then something is waking it up and it can't go back. These processes don't mean much to me...

The audio out wake lock is caused by keyboard sounds, touch sounds and screen lock/unlock sounds. Turn those off.
The other wakelock seems to be your gallery syncing constantly.

Touch sounds were on, I turned those off. Why would those be waking my phone up in the middle of the night though?
How do I keep my gallery from syncing constantly? The only setting I see in the gallery options is to turn off my google account sync which I assume would turn off my gmail and other things as well?

Never mind, I found where to turn off photo sync.
Is it normal for touch sounds and gallery updates to keep your phone awake all the time? If so, what is the point of having them if they are going to eat your battery...

what franco are you using?

Here is a screen of my overnight usage. I don't know why but I've just noticed the clock has gotten stuck. Stupid thing.
*Edit* I have a few things syncing over night, and the LED was literally flashing for the entire time, I didn't check my e-mails on purpose to see what nine and a half hours battery drain would do when that bright little LED was flashing all night, not bad I reckon!

Phone always awake :( What's wrong?

Wondering if i am suffering from the volume bug See...
Charging overnight: http://i44.tinypic.com/9930j7.jpg - Yet my phone has been "awake"?!
After 2 hours: http://i41.tinypic.com/2dim6me.jpg - Discharge almost 20% already and you see the awake time?
After 4 hours: http://i43.tinypic.com/302tok0.jpg - Faint! 50% was drained in 4 hours!
My homescreen: http://i44.tinypic.com/260e6tx.jpg - You will say is my Beautiful Widget, but I removed it and still phone awake!
How can I troubleshoot?

Exchange Services is really high. You probably have a corporate account that is having sync issues, and keeps waking the device.

Yeah I do have a corporate email account. But it's set to push notifications should I receive any e-mail.

Run BetterBatteryStats to see what keeps it awake. There's no reason why Exchange services should be that much of your battery.

I think it is pretty obvious just by looking at your 2nd screenshot.

If u don't use Bluetooth (if ur rooted) , go to /system/bin and delete the file "bluetoothd" to fix wakelock
Edit: be sure to backup the file first

Yeah pretty sure it was the Corporate Email. I have since then remove the account and this is my result overnight from 100% downwards after 6 hours. VEry good results.
Thanks for your help.

My Exchange went nuts just like that, clearing the app cache didn't help but reflashing my rom over top again did, just cleared cache and flashed rom again and its back to normal, using 4% of battery or so on push...

Congrats on resolving your issue. Just to help others, is there any chance you know and could mention what o/s or version of exchange your work server is running? Exchange and/or the stock email app seems to be a problem for some but not for others. More info might just help someone isolate the root cause someday.

I did not flash. I just delete my account and readd it and it was fine after that.

Wakelock, better battery help

That's not normal. Whatever wakelock is keeping it awake is not captured in your WLD screenshot. Track it down in better battery stats instead, using "partial wakelocks"

Thank you...that's what I thought... I don't know what happened...so I went into partial wakelocks and everything looks like low %... But kernel wakelocks there was a lot of high percentages...

First thing that sticks out is drop box. It shouldnt be running for that long. Did you turn on auto backup? This will cause huge drains. If turned on turn it off. Also check in service running for 21 minutes... Turn off your gps. This is Google now constantly running and locating you to try and provide you with what it thinks is useful cards (weather, traffic, food in your area) I only then on my gps when I'm gonna use navigation. Otherwise all apps with gps access will start to run and kill your battery. Also I suggest greenify. It'll help a lot with things like Facebook, Twitter, Google search, ect. Wakelocks. Also removing or freezing bloatware helps tremendously with battery drain. And last carrier iq. Something that always runs in the background. Google search it or read up in the battery threads here on XDA. They talk about it a lot and how to try and stop it. Also this thread

although for the SGS5 it can be applied to our device as well

[Q] What is 'Held Awake' In Battery Stats?

I unplugged my phone from the charger early this morning and went back to sleep for a couple hours. Woke up and my battery drained 12 percent with no use at all. Check the stats and see phone was 'held awake' for almost the whole time and seems to explain the drop. Does anyone know what is going on here? Providing a picture below. Thanks in advance.

Some app keeps phone awake. When not in power saving mode my note never goes into deep sleep. I have manually shoot down few services (after reboot) running in background or my note using 5-7% battery power per hour vs 2.5% when in deep sleep mode.

Is there a way to figure out which app is keeping the phone awake? I go into the running apps section of App Manager and kill off any services I do not need. It seems this problem is spotty. Sometimes it does it and other times, I can go a few days with no charge with average use. But a 6% drop per hour with absolutely no use is killer.

Better battery stats will help you to find offensive apps. I always shoot down, tmobile acc, gba service, fb messenger, media scanner, samsung media hub, push service. Some other apps are "frozen" with greenify. I noticed that after I use my phone with chromecast it will stay awake even with wifi off. I have a habit to reboot phone every morning and stop those services to have a have good battery live for a day.

Cool. I also disable those. What is a good app to get better detailed stats? If I clicked app usage in that link, it does bring up what apps are being used.

I've got all gestures and everything else I can think of off, I even disabled "Prevent accidental touches" yet it's still draining the battery fairly considerably
Any ideas?

If your phone is rooted, check your deep sleep time in a kernel manager like mtweaks or ex. If it doesn't go into deep sleep, there's probably a app preventing it. You can probably find it under the battery usage in your settings. If you can't find it try DS battery saver, if that resolves your issue, it's probably an app keeping your phone awake. It also could be the AoD thats keeping it awake, I only know about this problem in custom roms, and I don't encounter it on my phone on OneUI, but this could be an issue aswell.

Not rooted unfortunately, shame they limited access to app usage, I mean even Android battery status has more info
Deep sleep seeems to work, battery drain in the morning is fine, this is through the day

Bit of an update for anyone wanting to see actual app stats, "Accubatttery" still works fine
