Very curious quirk On Android Open Kang Project ROM... Near Unlimited Battery!!!!

hi all...
soo after my comments over a week ago on the aokp website for this build, i decided afterall to take the plunge and update. i was on b26, so subsequently had to flash b27 and then this. everything has gone absolutely swimmingly with no issues at all so far....
HOWEVER>>>>>
I am faced with a very puzzling quirk. its by nooooo means a problem at all, infact it quite the opposite!!! let me explain.
i've started charging my phone in the evening these days for some stupid reason and then, when charged taking it off and going to bed. After getting this milestone on, my battery has been killed over night, draining to around 15%. Normally, it would drain to around 70% and be flat by the end of the day ready for charging again.
This continued for a few days when i decided to root out the cause of the massive overnite idle drain. I installed a fantastic free app called Badass Battery Monitor (which i highly recommend btw!), and over a period of a couple of days the offending app was weeded out. It was Nova Launcher. This had never happened to me before and couldn't understand it. So, as part of my diagnostics, I decided to confirm the findings by removing it and just using stock.
Over a couple of days monitoring, with exactly the same charging method, my battery levels returned to normal drainage with around 75% battery left by the morning. Fantastic. I had found the problem fixed it and got back to normal. Soooo where is the quirk i here you say!!!? lol Well......
On average, from everything i've read in forums, battery drain overnight while phone in standby is around 20/30%, so mine WAS right up there with the majority of you.
Last night, i decided to charge to full and then wipe battery stats. Which i did. Now, bare in mind here that I ONLY have the standard battery that is supplied with the Galaxy Nexus. I got up this morning, and to my utter amazement, my battery had only drained 2%
Now been incredibly realisting here based on average overnight drains, i was 100% sure that this was deffo an error. I have done everything from restarting the phone, taking the battery out, but still the level in my battery was saying the same.
As I sit here writing this, I have been streaming a radio station via wifi on the phone for the last 2 hrs, and atm my battery is telling me that it is STILL 85% full.
I am DEFFO not complaining, but i'm sure now, you can see why the hell i am so puzzled! HOW THE HELL IS THIS HAPPENING, because i can genuinely find no explanation at all for it

as a follow up, it is now more or less 5 hrs since my orginal post, and my battery is reporting that it is 75% full

Jeesh, 20 to 30 idle drain overnight? My phone drains about 3 to 5 overnight which is typically 8 hours of sleep.

Interesting quirk. Are you a heavy or a light user? It'd be nice to see how it drains after a full drain and recharge.

well, to see if what was been reported was correct, i've been an absolute heavy user today. i have wifi on, ive streamed radio via internet for around 3 hrs, ive been playing all sorts of games and watched a few youtube vids. and my battery is atm reporting 74% life left

so here i am, STILL very very puzzled..
my battery life is just going and going with no signs of running flat... have a look at these screenshots and give me an explanation as to why i suddenly have a super battery!

MAYBE you really have a super battery or your mobile is glitched and shows the battery like that due to laG?

I'm on miui and I lose 0% overnight. It just depends on the ROM, but 20-30% is ridiculous!

Your states do not seem super impressive. On most phones the screen is the biggest drain. You show 49% battery with a screen on of only 1 hour. After 33 hours you've only used your phone for 1 hour screen on. Thats VERY little.
I usually get 2.5-3 hours of screen on time for my galaxy nexus.

Thanks for the app recommendation! Been looking for something like it all day.

This will depend on ROM/Radio/Kernel user installed programs/sync etc but 2-6% is normal drain over night anyone with 20% needs to seriously look @ battery stats and work out what's causing wake locks.
Also not forgetting most phones need to bed in after a flash which can take 2-3 days before we see real battery info.

Battery Life Help!

Hey Xda,
I just got the One S on Thursday and I've been wondering about my battery life. Everyone , from reviews to here on XDA, says how the One S has good battery life but I think I'm having problems. Now mind you I've done about 3 full cycles of draining the battery then fully charging it from Thursday to now but my battery life seems subpar. For example I just woke up at 730 am at 100% and have been using the phone from then to now 823am. That's one hour of extremely light browsing on Xda with brightness low in a dark room and WiFi on. No calls nothing but browsing. I I rooted andcustom ROMd my phone yesterday but this has been this way since I got the phone. My battery life is at 87%. Is thanormal?

Screen was on like that whole 45 minutes
My phone drops one percent every 2 minutes of screen on use. it doesnt matter what i'm doing.
this sucks watching the percentage drop so quick, this is like my battery life on the vibrant after almost 2 years of use off of that battery -.-

So if you had screen on for 45 mins in that one hour, and you battery dropped from 100 to 87, I would say it is normal, not mention you kept WiFi on which uses quite a lot battery.
But I don't get what you said 1 percent every 2 mins, in that case 45 mins would cost you about 22, 23%, not from 100 to 87. So did I miss something?

Accurate battery life?

Just got a new Z3 D6616. This is the battery life projection I'm getting. I bought this phone because I heard great things about it's battery life. Also, when I saw a YouTube review, the guy's phone had a battery life projection of several days. Is something faulty with this specific handset? Am I doing something terribly wrong? Please advise.
PS. I'm at about 30-40% screen brightness with the adaptive setting on.

You should actually use the phone from 100% doing your daily stuff till about 1% and take screen of your on screen time. On screen time is what matter. They claimed to have at least 8 hours SoT with normal usage but the max I can get is only 4.5 or 5 hours.

I did a lot of reading before buying the phone. Heard about the "memory" screen or something that helps towards battery life. Several users claimed 10 hours SOT. Could it be the newer firmware that might have reduced it? I'll post the YouTube videos I saw shortly.

I use brightness at about 1/3 and have location and autosync on. I get about 8-9 Hrs SOT in a 36Hrs period.
At first even I got 4-6 Hrs SOT until it calibrated over a few charge/discharge cycles.
It takes a few cycles for the battery to calibrate, if you want to do that faster do the following:
1. Drain to 0-1% with normal use
2. Do a full charge till 100%
3. Do another full discharge (Dont charge in between)
4. Do another full charge till 100%
5. Now just use it how you want.

Thanks! Guess I'll have to report back report back after a couple cycles.

I have the same problem, I have enable the stamina mode, have the brightness at half and auto,and the battery won't last for one day,as an example today when I get up after I unplug the device it go from 100% to 99% right away and now after 10 hours without game,photos just Internet reading over WiFi the battery is at 31%. It doesn't seem normal, what should I do?must go to service?

I'm at 59% and my phone predicts 1 day remaining.
D6616 as well
I do suspect an app draining my battery though...

Nope, 1 day 19 hours standby
Well, it says 23 hours now... and 1 day 18 hours in Standby mode.
I also have no power saving features enabled, with max brightness..
I can get 6+ hours if I limit my brightness, but I settle for less with max brightness throughout the day.

Could it have something to do with the display image enhancement mode? I'm using X-reality. What about you?

I have it turned off, I can't really tell a difference..
Sometimes my "battery forecast" is low like yours though, I wouldn't worry about it unless you're actually getting bad battery life.

The battery life I'm experiencing is worse than the "forecast", which is essentially what worries me. Regardless, I've no right to whine unless I've cycled the battery completely at least once since it is after all a brand spanking new phone.

I doubt I'd get the 24 hours from now with my current use either. As long as it lasts me throughout the day I'm fine.
I can generally go the entire weekend without charging my phone though.

Ive gone through 3 Z4s (Cosmetic defects/lightbleed) on my 4th Z4, all of the were bad until they were calibrated within a few days.

Lol yes.

I fully discharged and recharged my phone. Now I got 18 hours usage, including 7 hours SOT with the screen on max brightness for half an hour. It's getting much better now, certainly a huge improvement over my previous phone!
Sent from the inner sanctum of my mind.

That's more like it, it should get a little better.

Please have a look towards the end... My phone's been awake when I was asleep. Is there an issue with this phone deep sleeping? While I get a good SOT, the idle drain is too high! Please advise on how I could investigate if a particular app is doing this. I used to use "wakelock detector" but that no longer works without root.
EDIT: Stamina Mode always on.

I have the same problem too... Whenever I leave the phone idle, even with the stamina mode on, it still uses the battery as if I was using it.

How's your battery life

I love everything about this phone but the battery . Im hoping to get 2hrs of screen on time . Anyone else have issues with the battery. Any tips would be appreciated.

Try turning off the Always Scanning for WiFi option. Also, change the Sync settings for apps you don't need to be synced at all times. And Location setting to Battery Saver.

When im at home i can pull close to 4hrs screen on . If im not on wifi the phone idle is terrible. I probably drain 6% or more per hr idling. Its hard coming from a note 4 , but i guess it is what it is.

Draining at 6% per hour is not good & unusual. But for Android 5.0.2, it seems about right, unfortunately. My N5 drained at that rate before the 5.1 update.
On my S4 with its 2-yr old battery, I drain at 3 to 3.5% per hour on idle with both WiFi & LTE turned off.
On my N5 with a new battery & 5.1, I idle drain at 0.7 to 1.5% per hour.
I'll add my battery drain rate once I get my S6E tomorrow.

This is mine on light usage. I noticed etter after a factory reset. Heavy usage is between 6 and 8 depending on wifi

I'm debating going to get one of these... My Note 2 keeps not charging and the stock battery died in 1:10 (from 50% to 1%) during a run yesterday. I was using spotify and mapmyrun.

Today is my first day after first full charge and my battery drains at ~3.5% hour, per GSAM.
I have screen brightness at little bit below the half-way mark with Auto Brightness checked.
I disconnected my phone at 6 AM and right now, it has been on 16 hrs 30 mins. I have gotten 2 hrs 30 mins SOT with 45% left.
Wifi active for 6 hrs, LTE for about 1 hr.
Screen has used 52% of my battery, Wifi 15% (5.0.2 shortcoming), Bluetooth (2%), Held Awake (0%), Phone (0%), Phone Radio (0%), App Usage (31%).
So far, the S6E is outperforming my Nexus 5 on 5.1 with a brand-new battery I swapped in on 4/1/2015.
Happy with the S6E's battery life, especially considering it's only 2600mah.

a little over 6hrs and it went from 100% to 14%. Granted 56%-23% were on a 1:43 run using Bluetooth headphones + spotify and mapmyrun mapping my way. Oddly, when I look at the battery usage, OneDrive is at 18%!

18 hrs & 37 mins off the charger with 4 hrs 8 mins of SOT. 17% battery left. I'm very happy with this. Update to 5.1 should improve it a lot more as it did on my Nexus 5.
Android System & Kernel battery usage is pretty decent. Those two on my N5 on 5.1 drains way more battery than it does on my S6 Edge.
When I'm not actively using my phone, the idle battery drain rate is pretty good - 1.9%/hour (similar to my N5, with the N5 being a bit better).
13 hrs & 9 mins off the charger with 2 hrs 20 mins SOT --> 52% battery left.
All this is without Root and my usual battery-saving Root programs.
Once 5.1 rolls out and if I decide to Root the phone and add battery-saving Root apps, I'm expecting to achieve 6-7 hrs SOT.​

Ive noticed that turning off location and disabling google now has helped my battery life a lot.

I love this phone, but the battery life is the one terrible thing. 7-10 hours seems to be the max. I might have to return it and suffer the summer until the note 5.

i'm surprised to hear about all the negative battery life issues on this phone. on my GS3, i'd lose 3-4% battery just driving to work - now I get there and still have 100%. maybe i'm just not as heavy a user, but the other day my phone was off the charger for 16 hours and I still had 43% when I got home - and that included using Google Maps for 20 minutes, texting throughout the day, and using a bunch of apps. when idle, I generally only get 1% battery drain. my only complaint about the phone is some of the UI that I can't customize, but it's only a matter of time before custom ROMs are available...

I lose 10% or more battery on the phone regardless if I'm using it or it is sitting with the screen off. When I drive the 45 minutes to work, the battery is at 89%-93%.
A 1hr run with it on my arm playing spotify/mapmyrun seems to use about 26%.
Basically, I'm always worried now about the battery dying when I'm using it.
at the end of next month, I have a 14hr+ a day for 4 days music festival where I can only charge it at night. 7-10hr battery isn't going to work for me. It seems bizarre to me that they made the best phone ever, but skimped on the battery.

drive to work today with the phone just sitting beside me, 100% to 86%.

Is your location on? I had to disable google now. Turned off nfc, advanced wifi scanning.

my battery sucks too :/
i live by the charger even more

with all the same activities that got 7-10 hours on my Edge, the Note 4 is getting 14-24hrs.

Battery is beyond horrible!
Wifi is off
NFC is off
What else can I turn off? I can't even get half day out of this POS.

I think you actually want Wi-Fi to be on. I find that on any android device I burn more battery when using cellular networks.

Battery Thread

Please post your battery stats here, including Screen On Time.
Thanks.

5 hours SOT and Still at %30

Android System and OS together are eating nearly 50% of my battery.

Same here. System and OS eating my battery.

20 hours with 4 hours SOT. I'm not complaining. Much better than the s6!

First charge with massive wakelock issues...

Completely impressed with battery life. Pretty solid so far.

Not sure how everyone is getting all these legit battery stats. I'm only getting about 4-4.5 hours screen on time.

I'm at 15% with 3 hour 45 minutes screen on. No so impressive. I charged my phone before I went to bed and lost 16% with it just sitting, while I sleep. So much for doze.

Having the same issues. Trying to figure out what I'm doing wrong that everyone else is getting so much better results.

Anyone else care to comment? I'm getting pretty mediocre battery life. I expected ALOT BETTER. I'm averaging 4 hours screen on time. Android system is eating 37% right now.

Same boat here, relatively poor battery life and close to 2%/hr drain when not in use. Slightly better than my S5 active, but not much.

Got the phone 2 days ago, it's a bit early but I'm not getting crazy battery life: I listen to music a lot (5-6h/a day - Deezer or Poweramp) and get 5-6%/hour drain, a bit less (maybe 2%) while idle. Coming from a Nexus 6P this isn't great...

Anyone else have heat issues, my phone got crazy hot and I was just using fliboard no gaming or video watching.

Give it a week or so before complaining
Mine took 5 days to settle
Afterwards a constant 6.5 hr sot sometimes 8

anybody having battery issues,cycle the battery completely and it should improve. when i got my S7 and My S6 also battery was garbage. I did 2 full cycles and man im getting crazy battery after..
anyone not knowing exactly what I mean by cycle heres what I did
use the phone til it dies completely DO NOT TURN BACK ON
plug and charge til its fully charged turn back on use it again til it dies
and AGAIN DO NOT TURN IT ON just plug and charge fully before turning back on.
that was 2 full cycles did wonders for me hope it does that same for ya'll having bad battery good luck:good:

I've done two cycles. I average about 23 to 24 hours between charges. With 3 and a half hours screen time.
