battery time just fell off

without doing anything new my battery time just droped off the face of the earth.. its down about 75%. i was getting a full day mixed use now all of a suden im getting 6-8 hours with just a few phone calls.
my awake time is at 16%
I havent done anything new that i can think of.
im using (and have been for awhile) the mugen 1800 extended battery.
trying to think what might be doing it and cant come up with anything i havnt found in the forums already.

you probably downloaded some app that is running in the background continuously. check with a task manager to see what's running, and then try uninstalling some recent apps to test it out.

thats what i was thinking but i cant find anything new running with the task manager

Could just be a bad battery? I'm having same problem, maybe worse with stock battery. I went from 100% down to 15 in like 5 hours just reading my RSS feeds every hour or so. I think I may have fried my battery using it to tether for excessively long periods.
You're not using your phone to tether are you?

Mine is way down this week too. Initially I thought it was Swype, but not so sure anymore because no other users are reporting problems.

Are you using Modaco's rom and kernel ? or any new kernel for that matter? Ever since I switched kernels my battery hasn't made it through the day.

I'm using gbhil's custom kernel and seeing BETTER battery life when used with setCPU (using ondemand setting with 'standby/sleep' profile turned on, and set to 160/480).

No I'm not.. Turned a few more newer apps off and still no good today.. I was at 5% batt left after 9 hours with about 10 minutes web browsing (not wifi) 4 or 5 text messages and about 45 minutes talk time. That's down about 90% from were I was a week ago .

I managed to narrow my problem down to the Taskiller widget. Removed the widget (still running the app full time) and all is well.

Last night I rolled back to before I used a custom Kernel. I rather battery life over speed. I need my phone to last from 6am to at the very least 7pm. I think once people get over the performance boost, we'll see a lot more posts relating to battery issues.

might be that too, i hope not as i love that keyboard. just having it installed shouldn't drain the battery, should it? im on day 2 with the custom kernel and i too noticed more battery drain. at 1pm my hero was fully charged. i only played a bit with the phone and made two short calls and it's down to 86% already at 4pm. i want to roll back but i do like the speed of the new kernel. ill see how it does tonight.

Yeah going back to regular input sucks. Swype was only some leaked beta version, we don't really have right to complain; however, I bet their end product will be much better. I just hope they'll release it as an app and not as part of custom Android phone so we can get it sooner.

figured I woud resurect this thread rather than start a new one.
yesterday I decided to RUU my phone to pull the completely stock apks out of it. after I did that I restored my backup of fresh 1.1 with gbhils kernel and now I am at 90% awake time spare parts shows that "android system" as something keeping it awake. any suggestions on what this could be? could it have something to do with restoring the back up with the kernel over stock without a wipe?

Huge Wakelock

What the hell is going on with my phone? I have this huge wakelock and no idea where it's coming from. I've always been on latest PRL/Radio and never had a problem before. I recently reformatted my phone and installed MikG 2.52. I have an extended Sprint 2600mah battery and i believe it can do better.

Mine's even worse

Damnit, i was aiming for a 4 day battery life. This wake problem will be an issue!

I've had that issue for the last several releases.
It's not really huge. My phone is plugged in a lot to one of my computers, so I don't really notice it, but it is there.

wakelock
I have Miui 9.9 with SavagedZen 2.2.1CFS, latest baseband.
My phone never sleeps.

What battery usage monitor is that from?

Its built in Miui

The wakelock has to be something in the ASOP or Miui build. I installed a sense ROM (Synergy) and had no issues with wakelock.

I think it's MIUI, and only the builds after 1.8.26. I don't use MIUI anymore, I've since switched back to Sense, and I don't have it. Also, when 1.9.9 screwed up my phone, I switched back to 1.8.5, and I didn't have wakelock issues with that either.

I re-installed Miui and added Advanced task killer. Everytime I check it, Google maps is the only app running.

How did 1.9.9 screw up your phone, when everyone else ran it just fine? Matter of fact, I'm still on it

Calm down, I'm not trying to say that it lit my phone on fire or anything. It just screwed the install, and I decided it wasn't worth it anymore. My phone became slower and slower and more buggy with each update. AGAIN, I'm not saying this is the case for everyone. I'm glad it works for you. Honestly, I just like the way Sense runs better. However, that doesn't change the fact that the most recent MIUI builds have ridiculous wakelock issues. I'm not trying to argue with you like some of the people on here. That's just the experience I had.

Chillax homie.. I was just askin'

miui has been horrible battery for me lately also..i can only make it 5 hours maybe so I had to go back to cm7..

Log out of Facebook app, that thing causes major wake lock issues. I use phone usage app for finding my rouge apps.

That looks more like a monitoring app. Can you actually kill the apps that are running or can you set it to kill all apps automaticly?

I don't use the Facebook app so thats not it...I have even went as far as not installing anything to see if it may be an app and even stock it kills the battery..

Its a monitor app, a kill app is taskpanel. Best in my opinion.

Is my phone nomral? "Android OS" eats my battery

i have bought my GN last week, once i have got the phone, i immediately update it to KK1 (2.3.6, Hongkong version) via OTA.
i have read many posts on XDA that you guys with 2.3.6 are happy with the battery life, however, it is not the case on me.
as you can see, i have used for 5 hours after unplugging from full-charge, the battery drains from 100% to 65%, during this 5 hours, i had 10min phone call, took 2-3 pictures using build in camera, about 10 whatsapp messages
do you guys think it is reasonable?
what should i do to fix it?

These third party ROMs all seem to have one issue or another based on what I've read in the threads. Better to just root it and remove apps and tweak yourself.

I haven't had any trouble with Sheep Rom. I think the problem with some kernels is that the phone is not entering deep sleep. You could try installing setcpu and forcing it to 200Mhz while the screen is off.

Completely agree. Wish I never screwed mine up with Odin. Wish I could get back to my stock ron and just root, but my stock ron can't be found. I'm on the Hong Kong non modified ron now and am as close to being happy as I can get without selling and really buying.
I had problems with the sheep rom not showing apps in the market that worked and showed fine on the stock rom. Yeah yeah yeah, I know there was probably a fix but I'm not willing to spend all my time fixing silly **** that wouldn't be a problem.

I recommend starting with installing betterbatterystats to monitor wakelocks. That has identified my android os problems.

thanks guys for your suggestions on roms
i would prefer keep using the stock rom
will try to install betterbatterystats to monitor wakelocks, i will post the result after 1 day usage for our further investigation

Stock
I'm running stock for now, no root, and battery is pretty good. After installing juice defender ultimate, it's actually better than my GS2 battery.

rooted and using titanium to freeze a lot of the junk apps originally installed. Currently at 21 and 33 minutes with about 75% left. I never turn off wifi and have sync going all day. Browsing and a few voice calls. Not bad IMO

I would appreciate if you could you give us a list of those junk apps.

bunch to list (which I will do later) but go into running services. there should be a ton of crap (assuming your on stock) you can freeze. These are mostly stuff I would never use

Charged to 100% and left overnight...the drain was about 2% per hour...anyone can explain to me why..??...screenshots attached..

2% with wifi on is normal i think. just you off wifi then it will go < 1% /hr
You can use phone weaver to auto manage wifi. It will switch off at specific time and will switch on autometicaly at predefine time.
I manage to switch off data connection + wifi at 2am to 9am. and by bettery drain just 4% during this 7 hrs.

Hmm...but what about Android OS battery usage..its always high..??

wat is wrong with this, it showing you how much battery drained by OS. if your phone is workng then smthing shud use it na?
if your use is <1 %/hr, and that use, is with android OS mostly. it means not other than OS draining your battery.
Look to total battery draining/hr, and smthing (like ne service/application) over consuming battery, thn you have to worry for that..

And while using betterbatterystats...i saw in kernel wakelocks that vbus_present and deleted_wake_locks were on for a considerable amount of time...
Do they cause high android os use and drain battery..??
See attachment

Anyone else having partial wakelocks/worse battery life after JB OTA?

Just wanted to throw this out there and see if anyone happens to be getting a lot of partial wakelocks without screen on or if your overall battery life has decreased since installing the 4.1.1 OTA. When I first purchased the phone, I had very very few incidents under my battery info where I would have a session awake without the screen on. Post update, seems like I've got a ton of really small wakes with no screen activity. I have turned off Google Now and every GPS/Location setting I could find. Downloaded Better Battery Stats today so I'm going to see if I can get some better info on what's going on, new to the program though and I don't understand most of the info that it reads.
Prior to the update, letting my phone sit overnight I would maybe see a 3 or 4% drop over the course of say six or seven hours. Now I'm seeing a 3 to 4% drop in battery per hour, more if I'm actively using the phone. I'm going to do more testing, specifically overnight to see how it fairs. Just wanted to throw this out there and see if anyone else is experiencing any of these issues.

Im getting the fast dormancy symptom again... no matter what i tried I cant fix it... always connecting as HSPDA+ even if im not using......anyone got any ideas?

Hmm, might try a factory reset and not installing any apps at all and seeing how it fairs. By chance, do you guys have any of the stock bloatware apps disabled? Not rooted/Frozen, but just disabled via the apps menu? Wondering if perhaps disabling any of them might be a trigger.

Yea i'm getting that. I'm using 13% overnight now vs like 4% before. Not sure about the wakelocks though.
Some random things I've noticed are the blur widget resets itself alot. And the transition to the settings window on the left is laggy. How would one revert back to ICS? Google Now is not that worth it to me and the phone was smooth enough before. I'd take the battery life over the new features.
I did buy a second Razr M for my girlfriend that's still on ICS. I guess I can do a side by side compare this weekend.

I am loving the update.. only issue so far is fire fox crashing..no battery issues. Must be settings guys..
sent via xda premium with nexus 7-Xbox live-loneleppard add me

i don't think it is setting i have all my syncs to manual, and i have been noticing a lot worse battery life since the update i would have 18+ hours or so off charger with pretty heavy texting / game / some voice calls. Now i'm not getting close to that. I just disabled the fast dormancy service to see if that helps any, ill post back results

Just did a factory reset today, I'm not going to disable any of the bloatware this time, and I only installed BetterBatteryStats as well as updated all the default apps in the Play Store. Going to see if I get any wakelocks this time around.
Last night, after a period of 6 hours, I had over an hours worth of partial wakelocks from AlarmManager (subheading Phone).
-Matt :good:

I disabled Google Now and my phone used 7% battery over 6 and a half hours. A little bit better.

A factory reset (annoying as it is) helped me considerably. My phone was also seriously laggy before the reset...slow like my old DX on GB, much worse than factory ICS. It finally feels smooth now, like JB should.
Still seeing a lot more wakelocks than on ICS, but it doesn't seem to be draining the battery like it was before the reset. I also removed or disabled a couple of apps that seemed to be serious offenders (Accuweather was one).

Did a reset on mine as well and did not restore from Google backup. Still seeing wakelocks, but as someone noted earlier they don't seem to be draining the battery too much. With that said, the battery does still seem to tick down much faster than on ICS. One thing I did find that helped, although honestly it's not really a solution, is turning off data use when I'm out and about just answering texts and such. If I have data/wifi disabled, I'm getting closer to the battery life that ICS was giving, but then again who wants to go around having to toggle data on and off every time you want to look something up.
-Matt

Is maps showing up on your battery stats and you're not using it? If so, simply open the application. It should say "updated to the latest version" or something like that. If this is happening, this will solve your battery problems.
Happened on my Galaxy Nexus and was happening initially for this phone too. Hope this helps someone.

Modem Fast Dormancy Monitor Service Not Responding.
Me and my wife both updated to KitKat on our Razr M's. I like it so far. The pop up about modem fast dormancy bothers both of use. When you look under battery, it uses more battery than other apps. I force stop it, reboot and it comes right back. A chat on Motorola web site sugested to wipe partition cache. The link that was provide gives the wrong instructions. KitKat using the power and volume keys has changed. They forgot to tell some people. That didn't work! I sent a long email to Motorola telling them that someone messed up or they did this for a reason! I guess if you get mad enough you'll just buy a newer phone. If that one thing is fixed, we would both be happy. The white background in text take some getting use to also. I hope Motorola will help us, but I kind of think Razr M's will be considered OLD! They are betting we will junk them for a new model.

BATTERY DRAIN Android Core Apps HELP

My phone gets down to 70% after less than 2 hours. It used to take probably like 3 or 4 hours to get to 70%. But I've also looked at the battery status and it says "Android Core Apps" has used 33% after an hour and 47 minutes on the battery. Look at the screenshot I attached. Please help?!

I wpuld suggest Backup your apps/data using mybackup. Redownload ROM, go into recovery, wipe /data /cache /dalvic, reflash, and restore apps (apks w/o data I get FCS fro, apk+data) and data. Should fix your battery problem.

I say go odin back to stock mf9 and check whether your phone still gets hot or anything and to let your battery sink in for awhile then root and install your rom. Before doing this back up apps and internal memory since it will wipe it clean.

Same, MF9 update from MDL stock, unrooted
I'm having the same issue (coming from MDL stock, unrooted).
Is it the ROM? Is it Google Play? I'm not sure anymore, but i'm severely annoyed.

I had this problem until
I was experiencing the same issue on my phone. note I'm stock and not rooted. Until I updated the samsung apps.
For some reason the samsung app store had an update and was constantly waking my phone for the update, but because I had never agreed to the TOS(becuase I never opened the app) it wouldn't update resulting in battery drain.
I stumbled on the answer in a forum in regards to the G Note II. I was skeptical as to why it wouldn;t show the samsung app as being the culprit(something about using the google services core functions to update), but I know that it worked.
I'm sure an experienced dev can better explain why it shows as android os and not the Samsung app causing the drain.
If you already removed/froze those apps though I suppose you have a different issue.

Just did that and I never opened the "Samsung Apps" app too and just got the update. Hopefully this will fix it (Google Play services drain). Thanks man!

Shut down
Battery out for 30 secs
Restart
Worked for me

You could try a different kernel too. I use AGAT's Kernel. That kernel gives me SO much more battery juice.
