I was curious what kind of idle battery drain people are getting on their tablets/ROMs?
Measuring with Battery monitor Widget Pro, on my 8.4, running stock TW except for Towelroot, I am averaging -150ma.

Since I have an amper cable I can see the current the tablet draws when its plugged in with screen off / idle and fully charged. mine does this
0-0-0-0-0-0-0-0-0-20-0-0-0-0-0-20-0-0-0-0-0-20
so I would say its draws a quick 20 ma every 10 seconds - but since its plugged in it might not be in the deepest sleep setting that it would be when on battery.
anyways I have no problems with it staying at 100% or 99% leaving it off for the whole day unplugged so it has very good power management in my opinion. - just have to keep the wakelock apps in check
I updated from the ng1 build to the latest nk1 build and my idle battery drain is much improved with the exact same setup running. Now down to -40-50 mah.
I have terrible battery drain randomly for no reason and I don't no what is causing the battery to drain so much. I have attached an image is there anyway of seeing what causes this much battery to drain so quick?

You should install better battery stats, available here on XDA, to pinpoint your battery usage.
Looks like there was a really battery draining event that occurred quite suddenly?

I noticed in the screenshot you have might GPS on, there could be an app running in the background abusing GPS or polling it too quickly (look for a blinking / solid white pointer Icon in the top left of the statusbar, this will tell you if something is requesting location).
GPS will drain battery very quickly and should be disabled unless it's needed.

I've been searching but haven't found what I need.
Yesterday I was playing a game and my phone froze so I did a hard reboot. I was at 77% before the reboot. After the phone turned back on I was all the way down to 41%. During this time my phone was running very hot. In fact it ran hot all day at work and wouldn't charge. After the first battery pull, the battery dropped I did a third battery pull and things turned back to normal.
I'm running Blend 7.1 with the FD02 kernel and FD19 Modem. Going to update my kernel tomorrow. I just switched back from AOSP. This has happened to me in the past as well.
Our phone anticipates battery drain. I've had the reboot battery drop, but despite the lower percentage, the battery drains slowly and increases during sleep.
You're not actually losing battery capacity; the OS is anticipating quicker loss and reflects as much with a lower percentage

Awesome. Just wanted to make sure it wasn't something that I had done wrong.
Hi!
I installed blackout ICS incredible in my DHD. Everything went well but I wanted to calibrate my battery.
So I downloaded Battery Calibration by NeMa from Google play. Before calibration my batterylife was about 12-24h depending on my use.
Now after the calibration my batterylife is about 5h!! And the same usage as I have always had, couple of calls, net surfing and maybe a little of Angry Birds and spotify.
Did I do something wrong or is my battery dead? My DHD is about 2 years old.
According to Google calibrating your battery (erasing your battery stats) doesn't actually do anything, so it shouldn't have made your battery life shorter. You could install BetterBatteryStats from a thread here on XDA to see if something else is eating your battery. Look at alarms and wakelocks.
Ok, thanks. I installed the BBS and I'll tell the alarms and wakelocks here if I don't find anything funny about them...
bananagranola is right.
- hit my thanks button if i helped you -
calibrating your battery basically tells your OS how much batter it has or doesn't have. IF you flash a rom at less than 100% battery, then the max amount of battery your OS thinks it has might be different from how much your phone actually has. Sometimes this can affect battery life.
The other thing is, did you calibrate at 100%, then unplug immediately? If not, that might trick your OS into burning your battery so quickly.
Otherwise, 12hrs to 24 hours is super amazing, I'm a semi heavy user, and I'll only be able to get 12-14 hours of semi serious use (8 hours standby, 2 hours on off usage, some of that at 100% brightness when i'm outside, and lots of music), end of that I have only 32% left. 24 is pretty amazing, I wouldn't be complaining :laugh:
Well when you simply reboot new stats are generated.

Ok, so I have had today the BBS running on the background. I tried one thing in afternoon, I switched of Wifi. Wifi was off about 3h and when I came back to home I switched wifi back to on. I have still 70% battery!! and about 12h without charging.
BBS alarms:
android, wakeups:83 (Is this much?)
com.google.android.gsf, wakeups:56
com.android.settings, wakeups:13
and the rest of them is under 10
BBS Kernel Wakelock:
wlan_rx_wake: 14m18s
PowerManagerService: 10m57s
and rest is under 4mins
BBS Partial Wakelocks:
AudioOut_3: 3min16s
Twitter sync: 1m56s
BBS Other:
Deep Sleep is about 10.5h
Wifi On/running is about 6h
Is there something wrong or is there something that uses too much battery? Could the battery be "damaged" due it's about 2 years old now?
Sorry for stupid questions but I find it very annoying that sometimes battery life is 5h and sometimes it's way more than 12h with same usage.

What you've got looks fine (which makes sense, since you had good battery life this time). Keep BBS installed. If/when battery life starts tanking, take a look at BBS and see if anything else pops up. If you've got more questions then feel free to post again here.
Although you might miss the customizations of the roms, aospX has great and I mean great, battery life.

Hi!
As many, i had the problem of battery drain (it would go from 40/45% to 0% in a matter of minutes).
I orderer a new battery (not the Kompson one, the original Jiayu battery, at least it was sold as original and it even has the same serial number my previous battery had), but the problem continued!
Anyway, after much testing, here is the "solution" i have found:
As soon as you see the battery drain starting (it´s very easy to notice as you already know), go to battery settings and look at the percentage that each process spends of battery. Usually, before battery drain starts, everything looks normal, low consumption throughout all apps. But when the battery drainage kicks in, the last app you opened has an unusually high battery percentage consumption. For example, i have seen my ColorNote app at 45% consumption, Whatsapp at 50%, Reddit at 48%, etc...
These are all "normal" apps, not some shady app power hungry. What i do is, after i identify the app with unusual high power consumption (again, it´s usually the last app opened after battery drain starts) i long press on it (from the battery menu) and the i choose "Force Stop" on the app.
This immediatley stops the battery drain and the battery behaves normally and goes out at a normal rate until 1 or 2% battery!
I have tested this many times and it never failed me. Please try it to.
I think there is a little chance to catch the very moment when the battery drop start. Today I've got battery drain very quickly between 50%-40%.
I also tried some these "fixes". But the only solution is to change batteries.
people and me personally, have also found out that the enabled auto brightness control , often consumes a lot of battery after about Android 6.0
have a look also on that.
I've just tested a new Konpson battery and the battery drop changed. With originally Jiayu battery I have drop with 25%, now after 10% I guess and phone can hold some times (30 min approximately) at 1%. It's a little bit progress ;()
Yes, I know these battery drain threads are getting annoying, but I can't seem to find a solution to mine...
What happens is that after charging to 100% or near it, I have a very small battery drain (like 11-14 %/h), and then if I do something a bit more demanding (games, substratum, etc) my battery drain starts to get a little worse (16-20%/h). Even if I return to my light usage after my heavier usage, the battery drain is still there...
Battery usage is calculated based on capacity used over time since last charge. It's an average, not a real time monitor.

I know that... Which is why I have reset the battery stats, before returning to my light usage. The thing is, the light usage drains much more battery after the heavy usage the before.
Reading through some battery threads I was told that the "proper" way to check your overnight drain was to charge up to 100% and not touch it until the next morning. I tried this last night and WiFi drain was in the 30% range (I used my phone before taking the screenshot which is why it's at 22%) with a total drop of 7% (100-93% over 8 hours).
Does this seem high?
I've got WiFi, NFC, battery saver location, mobile data, and double tap to wake on. The phone is rooted and I'm using a custom kernel (but I'm pretty sure it happened with the stock kernel too). I also have an Android Wear watch attached all night. On AOSP ROMs on my OP3T overnight drain was around 2% if I started at 100% and WiFi was never more than maybe 6% of total drain. Again, I'm not asking how to fix this, I'm just wondering if this is something that others are experiencing.
Thanks!
Mine dropped 2% over four hours of sleep. I'll try with battery saver on.
Mine averages about 3% in 8hrs with wifi on, I'll post a screenshot tomorrow, on freedomos using simplegx kernel
My WiFi drain is very low during idle. Like most flagships of this era.
mine is as same as op, but last night i charged it upto 74 and slept and when i got up after 6 hrs or so it dropped 2 %, strange ... maybe it's the way the phone is charged and calibrated for dash charging
I'm loosing 4-5% in 8 hours.

Thanks for these screenshots. Obviously I don't have nearly the SOT that you do in my screenshot, but it looks like if our SOTs were the same you'd probably have similar WiFi percent usage.
Mine's been surprisingly bad - at least, worse than my Moto G5S, Galaxy S8+ or iPhone 8 Plus were. I'm losing like 5-7% every four hours, my battery drain while connected to wifi at work is way worse than either of the other phones mentioned too.
All in all it's kind of disappointing considering how good the OP5T is in literally every other regard.

We may have similar WiFi usage. But my drain is about .5% per hour, overnight. I don't consider that high, and battery consumption has to be attributed to something. Here is my current usage since yesterday's charge.
On 8.0 the WiFi drain % is even lower, but idle drain per hour is the same. So it doesn't really matter.
Very bad.. Battery go. Down quickly in night..
My wifi drain is also really bad on the latest 4.7.4
Hope they release a fix soon...
Edit... I did a fresh install with stock 4.7.4 and it isn't as bad but still is present. At least it's more tolerable.

So I did another test last night (4.7.4 and SimpleGX kernel) and had 3% drain. With all the comments here I think the high percentage of WiFi is normal and probably not affecting battery life a lot. I am starting to think the kernel may be providing better results than stock 4.7.4 though since a lot of people are mentioning poor battery on 4.7.4.
I don't even know how long, all I can say is my battery drains 3% every 9 and a half hours. Both bluetooth and wifi was on. This is on the stock rom and kernal, not sure how you guys have such high battery drain... Are you guys sure it isn't another app hijacking your battery? Because from my experience the battery stats isn't always perfect. Sometimes I was told that it was my screen (on my old phone) in which it was actually a 3rd party app. After removing the app, my battery drain went a lot slower than usual.
Has anyone tried this toggle in Developer options?

Just tried that setting last night and it doesn't make much difference.
For all wondering I have an Android Wear device connected 24/7 and location set to battery saving. I also keep NFC and data on all night. I'm not using screen-off gestures though.
I wish it was only 7% or something like that on my OP5T.
I used to be one of you 3%-battery-"drain"-at-night-guys, until the official update to Oreo. Now it uses 36% in 6h38m, of which WiFi is reported being 29% (1044mah, despite 0m active and background usage reported). There is 2.8MB additional use according to the WiFi data usage report that was set to count from today, yet the numbers per app have decreased, so there goes reliability on that. I haven't added or removed any apps, only wiped cache after the update. On standby, it only takes 18 hours for it to drain, which used to be several days.
Another weird thing is that WiFi is terribly slow since the same update, but only on this device. (No numbers yet)
Right now my plan is to test all the mentioned related settings, as well as WiFi off, make screenshots after each nightly test, and finally do a complete wipe and perform the same tests with a minimum of apps, and then redo them again with my usual set of apps. It could still be one or more apps that misbehave on Oreo specifically I suppose, so if there's any indication for that, I will start eliminating apps one by one until I find the culprit.
