App that can record battery status

I need an app which can record battery status against time and also tell me what has caused the drain at a particular point of time. Is there any ? Please advise.
I need that as I am facing a weird issue where my battery drains till 60 normally and after that it suddenly falls to 30 and from then again it goes on normally . It happened twice and I am worried about what is causing this ..... any idea ?

Battery Graph will display battery usage but as far as i'm aware it won't tell you what app etc...
I think there is one called Juice Plotter although I'm not sure how much more information that will give.
The stock Battery Usage thing in the Settings/Status will help with what percentage of the battery has been used up until that point. e.g. if you are on 60% then it will display a percentage of that 40% that app has used.
e.g. 25% (screen), 10% (cell standby) etc etc!

"Android OS" drains battery

Hey folks,
i am using Oodie's 2.7.6 MIUI rom and the air kernel v4.4. i am experiencing a rather annoying battery drain. the phone has been running ~15h on battery and is at 63%, however I haven't done anything with it except for checking FB once.
The phone is UC and UV (100-880mhz, voltage all down at least 25mv). according to the battery monitor it seems to be "android OS". how can i figure out which process exactly keeps on draining the battery?
push notification is active for three apps (google mail, kakaotalk - sth like whatsapp, facebook).

37% in 15 hours is roughly 2-3% an hour. You're probably not going to get better battery than that since that adds up to roughly 40 hours of standby which is very good batter life. Android OS is at the top of the list because nothing else is using power (it's a relative statistic).

Most definitely. From the looks of it, you barely even used your phone.

this is exactly my question. the battery drain wasn't this bad before. Even with slight to normal use i could go around 30+ hours without recharging. now the battery is done in the same time without any usage

i had that on quite a few ICS ROMs myself... turning auto rotate off fixed it for me, maybe it does the same for you

WiFi & GPS?

So I'm running the 8.27 nightly on CM10.2 on my d2vzw (stock kernal) and I'm getting massive battery drain. Looking at the battery graph, it's showing my GPS and WiFi as constantly on, even though they're both clearly off in my settings.
Does anybody know what would be causing this?

Nobody?
I'm getting over 10% battery drain per hour w/ absolutely NO use (like 30 sec. of screen time per hour).

first, install something like GSAM: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm&hl=en
or better battery stats (BBS): https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
charge to full, unplug, and let it do its thing for a day and see what is taking your battery life. more often than not, it's going to be a rogue app that's constantly syncing and/or pulling data.
also, you're running a nightly, so it's somewhat expected that you are going to have weird issues...

Battery indicator problem

Hello, I have one problem with Xperia E3's battery indicator . Generally battery condition is not a problem and drain by whole night is about 1-2%, but sometimes through the day I can notice a 5-6% drain by a 1 h when it's in sleep. There's no apps in background and battery drain sometimes appears unexpectedly. It can drain a 1% throgh the night, but it can also drain 5-6% per hour still with no apps in the background. Also I've noticed that my battery sometimes is not full charged, e.g after whole night charging, in the morning I can see 97% or 96% and it's still plugged but not charging. What do you think, it's problem with battery or just software issue?

New Galaxy S7 Edge overheating and rapidly discharging.

BIG PROBLEM
A brand new, fresh out of the box Galaxy S7 Edge [Exynos] (came pre-loaded with Oreo 8.0), merely 5 days in use is overheating (gets to 41°C) and draining its battery strangeley fast (about 1% every 4 mins whilst on 3G or LTE). No apps have been downloaded from the app store and there are only a few screenshots on the phone, other than that it's empty!
I first ignored the overheating when I set it up as by default it had been charging via fast charge so it was understandable. The first day the battery consumption was "ok" since it was just idle and i was bareley using it. The following day I connected to the wi-fi and I noticed it was draining the battery pretty quickly..almost 1 % every 7 mins even tho the screen was dimmed and most apps had been "optimised". I was also worried about the "cell standby" drain which was about 2% every 1.5hrs.
But things began to get out of hand when I began using the 3G connection to watch youtube videos, after just 8 minutes the phone became scorching hot to the point where I couldn't use it for a while. The battery percentage was falling ridiculously by around 1% every 3 to 4 mins, with the display on 40% brightness, apps optimised, background apps limited and all the other tweaks to save battery life being utilised. Location, BT, Wi-fi, NFC and auto-updates(GooglePlay) were all of and it was still getting hot.
Then I allowed it to drain completley to 0% but before that I disabled "fast charge" , it took 8 hrs from 2AM to around 10:14 AM to reach 100%...but this did not help the battery drainage as it was still the same as before.The cell standby reported 3% use in 12 hrs which is abnormal since other S7E( Nougat) users only got a hit 1% in 8HRS. I then came on XDA and saw that many other S7/Edge users that are running Oreo 8.0 were experiencing the same issue with no resolve... I have tried ALL of the following with not a single positive result:
1. Soft reset and wipe data cache partition. 》no difference made
2. Enabling "mid power save mode" to limit CPU speed and background apps . 》 still overheats and drains battery as before
3. Factory reset the phone (there was not much user data on it aside from 5 screenshots). 》did nothing to remedy the situation
4. Disabling any apps that might have been responsible for the overheating and battery drain uaing the Apps manager and the "app power monitor". 》no noticeable change
5. using the "Optimisine apps" option in the App manager
none of the above helped as the phone still gets very hot (when it is on 3G/4G data) and drains its battery much quicker than S7 Edges that were running Nougat a few years back.
AT THIS POINT I'M ALL OUT OF IDEAS AND YOU HELP WOULD BE GREATLEY APPRECIATED.

I recommend to update / flash latest firmware available.
Then install a battery stats app like Better battery stats (BBS), record an idle dump and post it in the BBS thread (https://forum.xda-developers.com/t/app-2-2-05-oct-v2-4-betterbatterystats.1179809/)
There are some experts analyzing your stats and giving advices how to optimize your system to gain better battery life.
