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.

Mysterious draining of battery on my One S

My One S with no phone call or surfing the whole day and now its down to 20% since happening the last 2 days.
I have not reboot my phone and I go to Battery Use to take a look and it say this today:
Screen 85%
Android System 5%
Androis OS 5%
Wi-Fi 2%
Cell standby 2%
How to troubleshoot this?
Thanks!

Ya reboot your phone theres a bug somewhere and it likes to drain the battery fast.

I did reboot yesterday cause it was totally drained. I am going to reboot again and fully charged and see what happened tomorrow evening.
I thought the "Battery Use" thing would tell me lots of thing and it did not.

Ya soon has you see it draining you want to reboot, no app will tell you its just a random thing and can drain it really fast.

You call this mysterious...? Mine had a drain even when my Phone was powered off But after reboot, removed some apps, all is fine now and my battery is doing great.

As in it drain like if you had it on and had this bug?

At that time, my phone was draining very fast, during the night (flight mode), lost 20-30% and when powered off for some hours (5-5 hours) it lost about 15%. Now when in flight mode during the night, i loose max 1 %

Hmm ok that don't sound right, that really is one messed up bug.

Before I install Vonage and Viber, everything was OK.
I uninstall Vonage and it still drain.
Now I put Viber back and see if it drain. I will reply back tomorrow.
Anyone have this problem with this 2 app? I need a VOIP that doesnt drain the battery.

I have viber installed, no problem with it.

How does the battery drain on your S6?

On my G3, when I fully charge the phone, it would stay at 100% for a VERY long time before dropping down to 99%. The most I've gotten out of the 1% before was about 25 minutes of SoT.
On my S6, once the phone is fully charged, it seems to drop to 99% very quickly, within just a couple minutes of using the device.
What causes this difference between the two models and does your S6 act the same way as mine?

So far my GF and I notice the battery drops quickly also.

Battery is terrible!!! Drains at about 10% per hour.. And I'm on the latest available stock rom.

That's pretty damn good if it do so. That's 10 hour SOT.
I can barely get 4 hours SOT.

Battery life is good for me.
19hrs since last charge, 52% power remaining. Screen on time of 1h 15min.

Yes but look at the great standby time.
Genetic is inline to get around 2-3hrs SOT with almost 40hrs Standby thats not too bad actually

But on screen time ia surely more important

Sure SOT is important but it depends on your standby too. Example 6hrs SOT with 8hrs Standby is kinda expected and normal. If you can get 6hrs SOT with 24hrs Standby the that is mightly impressive.

True but 19 hrs standby and 1 30 on screen is awful. That means you picked up the phone and drained it half way in an hour and a bit

Im not sure you get how it works bud.
That 1.5hrs SOT was not achieved in one continous sitting.
If you read my previous post i explained that you can get 6hrs SOT with the S6 easy but your standby will be short say around 8hrs. If you watch videos no stop on the S6 you could probably get 7-8hrs SOT before the battery is flat. This is normal for the S6.
Basically: Long SOT = shorter standby
Long standby = shorter SOT
The Holy Grail is Long Standby + Long SOT
EDIT: Im only referring to the S6 in my asaumption. There are flagships out that can get long standby and long SOT already out there namely Note4 and Mate7.

I have pretty terrible standby time though. An all nighter drained 10% but if i use the phone continuously i could get 4hrs of sot lol
Brightness was on auto

I get about a day standby with between 4-5 SOT.
Overnight drain is around 3-4%, I normally sleep around 7hrs a night.
I'm using XtreStoLite seriously debloated ROM, Ktoonsez 920F Kernel.
Also using App Ops and Disable Service to kill Google Play Services wakelocks.
Hope this helps you get better battery life bud.

Playing music through streaming music app Simfy, doesn't require the screen to stay on.
SOT isn't the only way to gauge a battery's performance.

Haha you guys took this thread pretty off-topic. My question was more related to the actual way your battery drains vs battery life.

Apologies OP didn't mean to derail tour thread.

Hmm i wouldnt want to root and unlock yet. Im gonna give it at least a month or two because the rattling home button is quite a concern to me. Even though its not really that bad

Man I must be lucky cause battery life for me looks REALLY good, especially considering the small capacity and the 2k display. Last night I fell asleep in front of the TV with my phone at 20%, woke up this morning and it was still at 20%. It's sipping battery nicely. I'm happy!
Edit: I'm all stock using the G920i. My brightness is controlled manually indoors, automatically outdoors.

I noticed the same thing with my S6 the first night I got it. It came with 50% battery and after an update and me playing around with it a bit I went off to bed at about 23%. The next morning I woke up and it was at 22%. I consider that to be exceptional considering nothing was disabled and it wasn't even on its first charge.
Unfortunately I haven't been able to fully set up my S6 due to exams so it's been sitting on my desk looking pretty. I'm still using my S5 for the time being and plan to fully switch over to the S6 in the next few days!

The battery on my edge seems to drop 1% every hour.

Mate 9 Battery Life (pls help)

Hey Guys, i got my Mate few days ago... Is this a good battery life? Or is there something wrong with my Mate? I got 2h SoT and I'm on 50%.Can you poste your Battery life down below? Thanks <3

I get about the same battery performance. Others seem to get way higher numbers but I don't mind it anymore, I'm happy my phone can last a day hahaha

You should get waaaay more... Do a factory res, if that does not work see of some app is drainig, if that is not the case return the phone cuz that is just too low...

Just an exemple... 44% yet...

Use a different FB app. SCrew instagram and SC.
Metal for FB and Twitter works great!
Set screen brightness to 35% max with uato brightness ( only allows it to go to 35% )
Disable bloatware
TURN OFF battery saver in my experience it drains faster.
Turn GPS on low ( and then turn off. only use when needed )
Make sure to watch for power hungry apps. I found a factory reset, setup the phone and apps and then let fully charge overnight helped.
Also, I noticed the trickle charge issue is still here. If i disconnect at 100% for 5-10 minutes then plug it back in for 10 minutes ( even if at 100% ) it definetly helps.
MAke sure to install GSAM ( and do their enable mroe stats ) and monitor from there. its MUCH mroe accurate than huawei's built in. on a light day i get 2 days 14 hours with 6-7 SOT. haeavy 1 day 18 hour ( 2 days for me ) i can get 8-12 hours SOT.

battery

Who else just straight up turned on power saver when they got the phone? I tend to use my phone for streaming anime from VRV and Netflix and watching YouTube videos...so I instinctively turned on the feature....and wow does the phones battery last with it turned on lol

What percentage drain per hour idle are you getting? I'm at around 1-3%, but I could have sworn I was getting way better when I first got it.

Well last night I forgot to put my phone to charge and it was at 85% and I woke up to 53% I fell asleep at 12 AM and Woke up at 7AM

If you get EX Kernel Manager you can enable a notification that will show percentage drain per hour when both active and idle! Sounds like 4-5% drain an hour though, not especially good. I'm sure you could get it down even farther! Check out ForceDoze.

The battery in the u11 is very good and a good addition to it is the htc app "boost+" from the playstore as it controls apps in both foreground and background, also it can change resolution of apps and games to save more power.
