[Q] Sudden battery drop?

Ok, i searched and couldnt find anything like this, so if there's already answered somewhere please point me in the right direction.
Lately, sometimes i've been getting these sudden drops on battery when i check the chart it looks something like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Info:
Stock JVT ROM
CF-Root 4.3 Kernel
Yes, i've flashed my phone with another ROMs (CM7.1, JVS, JVT) and yes, i've calibrated the battery. I started getting these even before i started messing with the phone's ROM/Kernel (with the stock unrooted JVH the phone came with).
Is it normal? Is there something wrong with the batery?

That looks more like your phone is doing a reboot. When your phone reboots it uses some battery so the "stats" will show lower after the phone have booted again.

i didnt reboot my phone and i don't really think it rebooted (not sure tho)

Noticed it looks like there was a signal drop at that time? When your phone loses signal it spends a lot of power searching for it, so that could explain it.

That screeny clearly shows a red area in signal line, so certainly signal dropped so it could be the reason for such a huge battery drop in such an instance. Has happened to me before, when I keep my phone switched off for some minutes.

[Q] Battery loss from "Modality Service"?

I'm getting some fairly significant battery drain from something called "Modality Service." It probably wouldn't annoy me so much if I had any clue what it was. Anyone seeing anything similar? Any idea what it is? My searches on the matter are coming up empty.

On and off through the day.
Interestingly "Modality Service" hasn't shown up at all today, with 7.5 hrs on battery. It's pretty intense when it does though, and I'm still deeply curious.

I saw this on someone's screen shot the other day, googled it and it didn't return anything related to it.
I think the use who posted had data disabled for most of the battery cycle, maybe it has to do with that? Not sure though

I have the same issue. I noticed it yesterday, I had very low usage and it was the top battery user. I clicked on it and it said it used GPS for the whole time my phone was on but I have GPS off, so that was odd. Also I checked into BatteryStats+ and it didn't even have it using my battery. It appears it isn't affecting my battery life because my CPU usage was only about 2s. I have no idea what it is though. I posted this on G+ and a guy replied saying he was on the phone with Motorola multiple times and ended up getting a replacement. I'd prefer not to go that route...

I too just noticed this last night and today. Last night it was showing using 48% of the battery and today using 38%. I found the service and force closed it. Not sure what it does or is.

Do you all have moto assist activated. It's only an issue for me when moto assist is trying to determine if I am driving. If I disable the driving portion, modality service never appears

battery/heat output wtf over, signal sux

OK I know phones put out heat but not with the simplest of tasks. I mean this is ridiculous if I play a game on it it gets smoking hot. My wife's nexus 6 doesn't even get warm and my s 5 I traded in for this barely got warm even with heavy use. Now onto the battery omg it drains faster than a 454 wide open does anyone have any advice or work around that actual work to improve both of these issues I am rooted have greenify, and tibu with some bloat frozen but still no noticeable difference thanks in advance
Oh yeah did I mention that the signal sux ass I'm constantly loosing lte coverage and it takes forever to even load the playstore....

I can literally sit here on the lowest brightness, everything disabled and watch the battery percentage go down. On super light use (navigating settings etc) it's warm.
Tried stock... or on clean rom...same.

Just charged to full, did a factory reset..Started fresh no restore and it went from 100% to 94% in less than 8 minutes. Is this a joke? Lol yeah this one is going back! Oh and those 8 minutes we're very very light use..just navigating phone.

ugh
I've been up for 3 hrs and I'm down to 52% I am using my tether but that's it. Think I might take this back and try the edge or another s6...I heard lollipop 5.1 is suppose to fix these issues any buddy have an info what so ever on the problems causing this. I love the phone but something needs to happen here and fast

3 hours tethering and you only lost 48%? That's pretty good. Tethering uses your cell data (battery kilker) and constant WiFi (battery killer) while keeping the CPU out of deep sleep to process routing for the tethered devices.

Yeah I know it eats battery, I don't have Internet where I live so tether is all I get it blows I'm also comparing to my wife's nexus 6 and my s 5 which both never dropped at this rate.

I get as good battery life as my N6, which is not as much as I'd like, but it's good enough. It's 2 and I've only dropped my phone on wireless charging for a few mins, and it's at 74%.

Play services 7.5 drains battery

Hey guys, my Moto X used to be able to get OK battery,but since the 7.5 update, I lose 15-20% over a five hour period, which is quite disappointing. any fixes?

All of a sudden for me too, GPS is now eating up to 15% of my battery and the Android OS is at 11%... I noticed this this morning. The only thing I installed last night was Greenify...

Quite similar to what I have. Android system and Android os always on top

This is new for me. I normally have pretty crap battery life but services and OS are normally never this high. The battery on my phone is so hit or miss. It 's behavior seriously changes daily. I don't get it.

By the way, it got me to 8.30pm yesterday before I had to charge. As bad and inconsistent the battery is, at the very least I can say it gets me to dinner without too much babying. I'm just concerned when it drains much quicker than usual which means I can't use it as much for it to survive.

Battery Cliffs

Someone asked a similar question, but the last reply is a year old and the last reply was about settling. I don't want to just settle if I don't have to, I'm curious as to why.
Decided to try using a Droid 4 again, and I've been running into what killed me off of it in the first place: serious battery level issues.
It seems that every custom ROM I try has a broken battery meter:

This is CM 13 or 14 (Marshmellow or Nougat), I don't remember. Was actually looking for a different screenshot and realized that this had what I needed too
(I dont know CM versions as well,so please excuse me if I'm naming them wrong)
I'd say that its a battery problem, but If I go back to stock this doesn't happen (90% sure on that. I'm in the process of doing some more testing and actually documenting things. Wanted to toss something out while I wait for file transfers to see if anyone else gets this.
I think I once used a modified stock rom and it worked without battery cliffs either. This is my second D4, and the first had the same jumps in battery too.
To be fair, the same thing started happening with my HTC Thunderbolt, albeit on stock and a bit more drastically.

Try resurection remix it works pretty good on my droid 4. Its the unnofficial version ported to the droid 4 by transil. It is in the development section for this device. Also if you use bettery battery stats you can get the apk here on xda. You can use this apk to see what is draining your battery.
