Look at the screenshot the two times don't correspond and there seems to be no awake time when I'm clearly playing many games on my device...

So I have this terrible drops from X -> 50% and X-> 20% (yes, I am aware of "battery drops explained" topic) and I was thinking if I could get around this false battery percentage display like this:
Let's say I will charge battery to 100%, turn on airplane mode, turn off every data/wifi etc. and just leave it for day or two until it is almost decharged. Then I will take a screenshot of battery usage graph and I make a straight diagonal line through it and see how I would like the percentage to be displayed instead of the real one.
I am not sure if I explained it good enough, but here's the example screenshot for you:
i(dot)imgur(dot)com/QEwJPeA.png
If we could someone force the phone (through apk or some kind of script) to show us te percentage like in the screen above we could AT LEAST have some better battery charge representation and some better knowledge about how much charge is really left. Even with 10% steps.
So to sum up:
1) Realize how your battery is behaving, dropping etc., take your version of battery graph
2) Create 'checkpoints' like in screenshot above and tell some application or script to show you the percentage like described in the screenshot as well
3) We can't get rid of drops on old batteries, so maybe at least we could earn some better % representation
PS.
I found a script that could be useful in my idea:

hi,
galaxy note 3 here with crash rom and rather good battery life - i'm a battery life junkie
actually I don't have a problem, i just want to understand something.
many people posting problems about mediaserver and mediascan draining their batteries. first of all i think many users dont undertsand that the 2 processes are different, but thats another story.
IN FACT, whenever i play may mp3s/Flacs with poweramp, my batterystats are showing a very high percentage of MEDIASERVER. after 3 hours of playing songs with screen OFF, the percentage is even higher than 4 hours of screentime with other apps! i was very afraid, but then i found out that the truth is, that 1 hour of audio playback with screen off, takes just 3% of battery. and even background playback with screen ON, takes just 10% of power per hour. thats quit good.
In the screenshots you can see 48% when starting playback, and after 1hour of playback with screen off, its at 45%.
in the BBS screen shot you can see that audioout2/mediaserver is keeping my device awake for the whole hour, which is somehow frightening, but maybe normal and as said, doesnt affect so much the battery life...
WHY is the percentage of mediaserver in the android batterystats THAT high than?
some may say its not a big deal and that i should be happy with my battery life. well, i AM, but i just want to understand....
Hi, I have FINALLY found a solution for the bug of mediaserver process with Poweramp. With the fade option enabled, mediaserver process starts when i change song while with crossfade option disabled the process stop.
Is there an app that measures the cumulative keep awake time per app versus time ... Along with battery percentage vs time. This would be useful in diagnosing apps that have excessive wakelocks and correlating there keep awake time periods with periods of excessive battery drain. As it stands right now with apps like better battery stats and the stock Android battery app,, you only know the cumulative keep awake or wake lock time as a single number rather than as a graph plotted versus time to overlay on top of the battery drain percentage graph. One always ends up speculating as to when that keep awake time actually occurred vs the battery drain.
So ideally I would want all of those statistics that come up in the stock Android battery app along with wakelock time, such as a CPU time total CPU time awake time etc versus time. A simple way to implement this would be to listen for battery percentage drops like many of the battery monitoring apps already do, but also record all of those other statistics and the current system time at the same time.
Is there anything already out there or anyone willing to add this functionality to their existing app?

This is a very late response because I found this thread through searching a question. But, are you trying to figure out if huge number of wakelocks that don't hold the device awake for very long cause battery drain? If so, that's what I'm trying to figure out. I have a wifi wakelock that kept the device awake for less than 1 min over the course of 3 hours. However, the number of wakelocks is over 2,000 so I'm trying to figure out if it is affecting the battery life.
Is that normal that I have only 4h30 screen on when using my phone only for texting and like 1h of internet browsing .. Plus 10 minutes of clash of clan .. Nothing more ..
I'm very skeptical about my battery life because I see that everyone having more than me with more heavy usage..
I installed wake lock detector and the top one is 1013 ( audio mix ) and the second one is android system which is audio mix too .. Don't understand why I have so " poor " battery life ..
PS : location and sync are off all the time !

BetterBatteryStatts from Play will give you info of the top power consumers. If you are on 3/4G a lot then the phone will use more power too.
i`ve got max 5hours screen on, on stock ane2 with root

It's not typical of course. That is obvious when you compare your time to the vast majority of other posts. You are clearly on the short end. But not unheard of either.
Why is impossible to discern since you haven't provided many details. 4.5 hours of screen time.. but how much time overall? How much connection time to Wifi and a lot of other things? Detailed battery stats showing how much time various apps and services are on would offer hints. If your net and texting are LTE connections and you have a few piggish apps, there you go.
You may have GPS off, but audio apps can be heavy draws because music play will spin hundreds or thousands of wakelocks. Some players are worse than others. But you didn't tell us which ones you are using or how much music play either. Some apps like Tunein can be abysmal. Apps that constantly poll the net like Google Now or poll the camera like Skype can put dents in your run time.
Perhaps you have a bad, damaged or third party battery. And so on and so forth. We don't have nearly enough details. All we can say for certain is that you appear to have a very short run time. But that wouldn't be at all unexpected if half of a dozen of your heavily used apps tend to be heavy draws. If you debloated your system, optimized a few things and made some tweaks, you might well find that your run time increased 50%.

Yeah you're right, i'll try to give more information,
for now all i can give it's that i'm on 3G/2G (no LTE) because i'm a Train driver and i travel a lot.. I plug off the phone from the charger at 9AM and at 9pm i have like 15-20% left.. with ~ 4.5 screen on
I'm not using music player because i'm listening music with my ipod. Google Now desactivated, Skype not installed, Facebook not installed too !
Location off and sync off all the time.. Wifi off too
All i do between 9Am and 9pm it's approximativly 300 text (sms) 50 whatsapp messages, 10 - 15 minutes of Clash of clan, maybe 1 or 2 Snapchat and like 1hour of internet browsing.. Essentialy News website..
That's a normal day for me ! Sometimes i might take 2-3 picture of place i like.. And maybe play an other game to pass the free time (but that wasn't included yesterday report and that's occasionally)
I'll try to take some screenshot of BBS and battery info today or maybe tomorrow to give a better report
Thanks for helping guys
Thanks for the details. That actually doesn't sound that bad.. after 12 hours of run time, you've got 15 - 20% left. The 4.5 hours of screen time is misleading.. giving a vague impression that your battery only lasts ~ 5 hours.
But actually, it's been on 12 hours.. with enough battery remaining to run several more hours so.. your overall run time is something like 15 hours, during which you sent 300 SMS, 50 miscellaneous messages, some Snapchats, 15 min of gaming, an hour on the net and 4.5 hours screen on. Nothing wrong with that at all. If you happened to use your apps differently you could easily see 7 or 8 hours screen on while more or less doing what you currently do. It's just that your usage happens to involve less screen time.
If I missed something, perhaps you could narrow down or elaborate about your concerns? Is there some use that you want to do during your workday that you don't feel you can?. But it you were just concerned that 4.5 hours didn't sound that good.. I don't think that is anything to worry about. Your overall usage when you explained at length sounds perfectly normal to me. If you want to aim for a straight number, you could tweak your phone, use inverted apps, etc and etc and gain another 3 - 4 hours screen or run time.. but to what end? Your current usage takes you through your workday with 20% remaining.. I'd say mission accomplished.

First of all I have never posted any questions online before so excuse me if I'm missing some info that I should have posted please inform me of any missing info.
My note 3 SM-N9005 has this very weird problem.
The battery drains 1% every 2 minutes. with airplane mode but wifi on, screen brightness on the lowest level, not using any application.
(If I'm playing a game or watching videos it goes from 100% to 0% in about half an hour or less.)
This rate is after fresh install of custom rom. I've tried more than one rom, I've tried stock lollipop rom, more than one Cyanogenmod roms and lineage Oreo 8.1. They all had the same battery consumption.
Plus whenever I check the battery consuming applications in android settings, The sum of percentages consumed by everything isn't anywhere near the actual consumed, for example the sum of consumed battery by applications is 9% and the battery percentage is at 66%.
I've changed the battery three times so far and tried the battery on another phone and it seemed to work just fine in the other note 3.
I've tried changing the charger but still the same.
I just want to know what is causing this fast consumption even though I've changed everything.
I have the exact same problem
