just started having an issue with the system process mdnSD draining my battery, is the top usage item. when looking at the usage stats for the app the total connection time is constantly going up.. physically removing the SD fixes the problem, as well as i have tried using a different card and it still runs. i cannot do anything to freeze this process (am rooted), as well as looking at wakelock and nothing shows up. putting the phone in safe mode seemed to fix it as well. i froze google services to make sure it wasnt a gps thing like some people have thought, as well as freezing fb messenger and tinder. tried wiping cache partition and nothing.
last time i had a problem with usage manager i just reflashed with the 5.0 fw and it fixed it and i didnt lose any of my stuff..
seems all those numbers continue to go out. samsung guy at best buy thought it might be backup related
edit2: it was determined to be caused by firefox being left open in the background on a certain websites that had streaming media i think. although overall FF battery usage was low and nothing suspicious on wakelock. admins do whatever you want with this thread

Hi, looked for similar in threads but found no resolution.
After charging and booting I noticed the battery draining especially quickly recently. When looking at Spare Parts/battery history it shows running at 100%.I drop down Partial wake usage and usually two highest programs are Android system and UID 10015(?). When these are then pressed it shows the up time but not amounting to the total since boot.
When opening both CPU Spy and CPUStats they confirm NO deep sleep time.
To remedy this I have tried various from simple reboot, to kill all, changing various settings, opening apps and most recent flashing new rom CM 6.1.2 from previous CM 6.1.0.
Now here's the weird part - no one remedy works all the time, it's a question of hit and miss, such as this morning it took 3 reboots to work, yesterday a mess around with some apps cleared it.
Oh, and I did a full wipe/factory reset when flashing.
One last thing the problem only manifests itself from a reboot, so once cleared it runs sweet until I switch off at end of day and charge it.
Hope you can help cos although the problems not life threatening it sure is bugging the hell outa me.
Thanking in anticipation
I'm trying to track down my battery drain issue. It seems to be related to data usage, since when the wi-fi is off the data indicator is going pretty much constantly. Using various apps to locate the running processes. Seems that latitude is running quite a bit, but freezing maps with TiBu does not seen to have a significant effect. I am on Illuminance 3.0 with the Samurai Kernal 1.4.2, but I had similar problems on Illuminance 2.0.1 I have not tried other ROM's lately, but since others are reporting excellent battery usage I don't think it's the ROM. I tried a fresh flash with TiBu restore of apps only with selective data restore and no luck. I would post a screen shot, but I can't seem to figure out the screenshot app from the market. Any thoughts on how to track down the offending app?
Additionally, I am having issues with the search button randomly activating.
How long is your battery lasting? How does it compare to what it was before? You could definitely try uninstalling the offending apps completely if you don't use them. Also, to save battery, I recommend using JuiceDefender. I don't use it all the time, only when I know I don't need constant internet access all the time. You can simply toggle it on/off from the widget, and it automatically turns data on when you unlock your phone so you can use it normally from there. Basically it saves power when you aren't using your phone, at the cost of not receiving instant notifications.

I'm playing a similar game of hide and seek and configured very similarly to you. I've just recently changed to the Corn Kernel to see if things may be different, and have replaced the battery with a hi-cap alternative.
I keep coming back to the email app as it is always sits in the high 30's in the battery usage chart. Swapped in a third party email app and the percentages dropped to normal ... but lost the syncing of my calendars.
Keep us posted on anything you might turn up. The ROM is great .. I'd just like to get more than 6 hours out of the battery.
Seems to be my enhanced email app. Froze it this morning and went all day with no charge, 12 1/2 hours and down to 40%. About what I usually get out of this phone.

In the last week or so I have picked up my phone three times and it has been dead.
The power button doesn't turn it on again.
I have to take the battery out and then restart it.
I'm running a rooted 2.35 JVT.
I have nothing untoward running ...

Could it be a dead battery?
otherwise, tried to wipe and (re)flash a rom?
The battery is fine, and the ROM has been there for well over a year with no problems.
Finding the root cause of battery drain...

There are a number of standard steps to run through to find the root cause of battery problems, assuming the drain is caused by the OS or apps and not actually due to a physically failing battery.
I have been tracking a few battery issues myself recently and this is what I have learned from doing some reading on XDA:
There are two free apps on the app market that are typically used to diagnose battery problems:
Better Battery Stats
CPU Spy
I would recommend installing both apps. The third place to look is in the battery details in the system settings...sorry I can't remember what they look like on Gingerbread because upgraded to Jelly Bean a couple months ago, though I do remember there was less information in the stock battery info on Gingerbread.
IF you are not, indeed dealing with a physically dead battery, then the root of your battery drain is most likely caused by a background process or app that is keeping the processor in a partially active state even though the screen is turned off and one would assume the phone should not be using any power.
Android OS will automatically change the running speed of the processor in the phone based on the demand of the system. If only a few background tasks are running and updating information the speed might be 200 or 400 Mhz. If the system is running full out servicing a graphic intensive game the processor will likely be running at the full 1000 MHz speed. The speed of the processor will directly effect the battery drain.
The expectation is that when we turn the display off (not power down, just put the phone to sleep) the processor should need fewer resources and slow down, tending towards a state known as "Deep Sleep". At this point the processor us using very minimal amounts of power. Any app or process that is active in the background will prevent the processor from getting to Deep Sleep. The CPU spy app will allow you to check how much time the phone runs at various speeds. Once you install it and run it, then reset the timers in the menu and turn your screen off for about 10 or 15 minutes. Then 'refresh' the timers. Normally, you should see most of the time accumulated in Deep Sleep. There are standard background tasks such as syncing with the cell tower, updating time, mail, checking alarms etc. That will engage the processor momentarily but they should be relatively short compared to the deep sleep time. In my case, an errand process was keeping my phone at 100Mhz constantly preventing deep sleep.
Once you know that something is keeping the phone awake in the background, you can use Better Battery Stats to narrow down which process or app it is the cause. This app allows you to track the individual processes that are consuming the most time and preventing 'wakelocks'. Wakelocks are essentially an app preventing the sleep state and are very well explained in this post: http://forum.xda-developers.com/showthread.php?t=1827676
The battery info in the system settings can also be used to give clues though again, I can't remember how much detail was included in Gingerbread..
If your problem only started happening recently, then it could be a new app that you installed recently, a feature or setting you changed recently or possibly a recent update to an app that was already installed. Try to think back at any recent events that could have triggered a change in the system.
Common problem apps I have read about are:
- Facebook - seems to be bad at using lots of background processor time. (Don't run this app but reading several posts shows its a processor hog)
- Google Apps that sync - Gmail, Chrome (syncs browser history, tabs etc.), Google location stats.
The wakelocks link goes into a great deal of detail and is hugely valuable in nailing your issue down.
Good Luck, let use know via a post if you find the root cause...
Sorry, maybe I wasn't clear about it being 'dead'.
The battery is 100% or thereabouts, no problems ever with the battery.
The phone looked as though it was turned off, but wouldn't turn on again with the power button.
I have to take the battery out and put it back again, then it starts on the button.
I've cleaned the contacts, and it still happened.

To me, it sounds more like a rogue process messing up power managing or response, but it's hard to tell what it could actually be.
For instance, you might come a cross a game that leaves your phone locked in max cpu frequency, draining the battery without explanation.
If it was me, I'd re-flash the rom from Odin, perhaps with an sd card wipe too.

I'm having serious battery issues that just started out of nowhere. I'm currently only getting about 4 hours of light use before having to recharge.
I'd like to look at what apps are using the battery but there are only 5 apps listed and they add up to only 27% (the highest is screen at 12%).
Phone is not rooted and I haven't loaded any new apps recently.
I noticed this as well. I used to use Better Battery Stats when I was rooted, so I didn't know if it was normal to act this way or not. Sounds like it isn't.
Currently having the same issue. Seems like my battery started tanking right around Christmas. I got a Huawei watch and originally suspected that but turning it off and leaving it home for a day didn't seem to help. The battery stats on the S6 are garbage and I can't track down what is going on.
Been noticing the same issue on my G920A. I tried doing a cache clear, but that doesn't seem to have helped. I went through all the running apps and services to try and find anything that could be eating the battery, but nothing seems to be reported that adds up to the amount that's getting eaten.
I use greenify for handling the hibernation of apps when they don't seem to act right by themselves, but since the phone isn't rooted, I have to manually run this operation - and that really doesn't help much anyway. Figured I'd add my experience to this thread just as a means of documenting the situation.
After updating to 9.1.0.252 I noticed faster battery drain. Did any of you experience the same behavior? I'm thinking to go back to 9.0.1.
Thanks
I feel the same

Don't forget that our device/battery is getting older with every update?.
It might look like new but mine is already 2 years in use.

I noticed faster battery drain on my ltr-09 as well. All is fine now. I noticed when i first upgraded location was turning on alot almost like it was learning when to turn on. Then it levelled out. Example opening google now at first it always turned on my gps now it doesnt. When i was on 9.01 i left my phone on battery saving for gps. You cant on 9.1 and i have seen alot of apps that used to be good with battery saving location now going for full with gps. Big bttery drain. Those were the differences i found. What I believe solved my battery drain was actually my battery getting all screwed up. I had this happen when i would switch roms and my battery stats would get all messed up. I solved it before and solved it this time with my p10 by running the thing right dead. Then pluging it in overnight with it turned off (no fast charging) Then I did it again the next night drained to dead , plug in charge with off ( no supercharging) and my battery life is better again. Hope this helps. EDIT After a few days of testing i still felt the battery was better but battery life still wasnt right. I did a factory installed minimal apps. Battery life was good until play store updated carrier services. I uninstalled updates to carrier services, disabled auto update. Then i actually disabled carrier services completely. Battery seems good now. From what i read carrier services is for next gen texting. Saw online others were having issues with this update.

Wrong, batteries get older with time and charging cycles. Updates have nothing to do with it and if you notice a drain right after one - it has nothing to do with the condition of the battery, it's the update's fault.
updates are huawei's way to convince you to buy a new phone
first they borked the camera, now they are messing with battery
I managed to improve battery life a little bit by disabling apps running in background and disabling unnecessary location permissions for several apps like @bigshowjh said. Like @bigshowjh said I found apps resetting their permission or settings after update. Still the battery life is not like it was before updating with the same usage behavior.

I have ran a couple of days with very good battery life. 11.5 hrs with 62 percent left. Seems like it used to be with Oreo. Overview of all I did was as follows. Clear cache partition, factory reset . Uninstalled Google Chrome (used Firefox instead) set carrier service to factory in apps three dots advanced. Disabled automatic update of carrier services in play store, then in settings apps disabled carrier services completely. Went through and disabled network access to every app that doesn't need it. I don't use Facebook or Facebook Messenger apps. I use them through my browser. Oddly chome on pie is a battery killer as well. I'm very satisfied with proformance of my P10 again.
My GPS is pretty much always off (unless I really need it) and the battery level still goes down by 9% during the night. It used to be 3-4%.
I cannot find carrier service anywhere.
In my case I can't see power hungry apps in the stats, standby process uses the most energy.

Settings, apps, apps again, select three dots in upper right, select show system processes. You will find it there it's a little hidden lol.
Still no carrier services for Play Store.
