Crazy battery usage after OTA 1.72.405.3 How to find out what is going wrong?

Hi all,
After instaling OTA 1.72.405.3 the android system is eating away my battery like crazy.
After 5 hours my battery was down to 29% (71% was used) and the android system was responsible for 60% of this. In my CurrentWidget log I can see that (with the phone in standby) it uses ~130 mA to ~160 mA.
Does anybody know what is going on or can anybody help me by telling how to find out what is going on?
[edit: If you have the same problem, please post a reply so we can find out if this is a big problem! Thx]

This happened to me yesterday! Found out that the system process had pegged out the CPU @ 100%
I couldn't fix it, and in the end restored to factory settings. Has been OK today but I killed the battery in about 4 hours.

Radio and kernel updated?

yes, i have the same problem! i posted another thread about it (titled constant sync after OTA update) as i first noticed the issue when the sync icon was always being displayed.
today my battery hit 20% after 6 hours with android system taking up 50% of the battery usage. its ridiculous!
if anyone has a workaround or a quick fix please post it up - this is untenable!

I have exactly the same issue, no problem with battery life before the latest OTA, and now the phone is dead within 8 hours with no usage, simply in the pocket with the display off.
Not happy at all, the phone is virtually unusable at the moment as any action accelerates the drain.

Strange! My phone is now with more battery life, after the update. It is SIM free ...

I posted this in another thread -
There seems to be a bug in the update for anyone who had HTCSense.com sync'ing turned on. Either disable all sync'ing for that and / or sign out of that account. It was consuming 100% of my CPU cycles and keeping the processor at the 1ghz mark. Once I disabled the HTCSense.com sync and rebooted the phone, all is good. I went from 100% CPU usage to about 4% and less when idle.
Personally, I'm not sure about HTCSense.com anyways. Way to buggy. I have all my SMS's backed up with SMSBackup+ to my Gmail and my contact / calendar is on Google. I've Wave Secure to lock down the phone if needs be / to find it. I think it's more reliable as well as I used to get a lot of "can't connect to the phone" on HTCSense.com and Wave secure uses at Text Message based system to activate the necessary features along with locking down the phone if the sim is removed / replaced! NICE!
Anywho, anyone who is having battery problems / finding the CPU is topepd at 100% try the above and see!!

I followed up with this:
I must say, I'm quite impressed with the battery life since the update (after I got rid of the 100% CPU bug).
I plugged the phone out at 11am this morning. Quite heavy texts (50+ sent today and at least that received). 10+ calls (incoming and out going) at 3-10mins each. Some Angry Birds, Some Market Updates. Disconnected my Facebook Acc and reconnected to cure a bug in the calendar (facebook entries were there twice), so all that data had to reload. Twitter usage through out the day. WiFi on all day. GPRS Radio only.
Now at 12.15am (so over 13 hours later), I've still got 50% Battery left! I would NEVER have gotten that previously. Not with the heavy use I gave it today.
How are other people finding it!?

Thanks for that. I dont really use any of the sense features myself so i've now disabled sense syncing completely and will see how it goes (once its fully charged again!). will keep this thread updated with any news from my end in any case.

I did notice the sync logo was up quite a bit... interesting!
Mine did it randomly... couldn't clear it so just went for factory reset which appears to have fixed it!
May turn of HTCSense however if it is likely to be causing problems...

I got the same Battery problem after new OTA and Im going crazy! What can I do? My battery lasts only about 4 hours now!!!!!!
Should I factory reset and wipe everything???

As ive posted in a few other threads i went into stock application manager and force closed everything i could to do with google, htc , friendstream, maps, facebook etc. After that my cpu 100% problem stopped, has never returned and battery life has improved compared to before the update.

I have disabled now HTCSense.com sincronization. I will see how this works tomorrow for me. I will let you know guys

I had htcsense.com enabled but to be frank I never really used it much...
disabled its syncing (every 3 hours I had set), rebooted, still had "android system" at ~65% and htc sense running at about 15% (tell me, I use launcher pro 99% of the time, is there any way to actually kill the sense ui? I swear its in the background)...
This did nothing, I tried actually removing the account, and even before a reboot the proc. usage dropped down to about 15%, which was apparently being used by the monitor I use (osmonitor). rebooted, let the phone settle, it did a sync, all seems well... So in my case an actual removal of the account was needed.

Try turning USB debugging on/off. I have it off after the last OTA and I have no /INIT problems. Maybe they fixed it...

I had the same problem, with the cpu running constantly at 100%. For me the solution was to remove the HTC Sense account, and then adding it again. After this the cpu usage dropped to normal.

well its been nearly 4 hours unplugged and i'm down to around 80% with around 30m of calls made and a dozen texts. not fantastic, but much better then before.

Did you try USB debugging? previously that has been mentioned as the CPU eater and battery hogger... just a thought..

Confirmed. I had the same exact problem and removing HTC Sense account did the trick.
I tried adding it again, but the cpu drain started again..... so I'll use it for some time without SenseSync.

well it seems i spoke too soon. i've just woken up to find that the battery died overnight. so sometime in the last 9 hours i've lost 80% battery whilst it has been on standby.
prateekgujral, i currently have usb debugging turned ON due to the /init problem. are you suggesting that i turn it off?

Weird drain overnight

Hey guys, I got this weird drain of about 1%/ hr over a period of 6 hours overnight with 2g data and auto sync on, the previous night with 3g data on I drained only 2% in 9 hours.
Apparently my phone has one hours of being kept awake by a wake lock named
mdm_hsic_pm0
And another hour by
Battery_monitor
Does this happen to anyone else?

This is the only thing i found in bbs thread
mdm_hsic_pm0 is afaik the same as l2 Hasic, just a new name under Jellybean, so its traffic related, i would keen an eye on my background activity..

battery monitor wakelock is almost related to the BBS

ssame thing happening to me..should i change kernel ?

i have same battery monitor drain and wlan_wake

I use to have battery drain on my GT-N7100 (and overheating problem). What turned out was that the Gmail sync on one of my accounts was going in a loop and never ending. When I fixed it, all went back to normal.

What rom / Kernels you peeps running? I had this once, flashed a different rom and no problem. Currently running Omega 7.1 with excellent battery life over night.

Mdm hsic is related to mobile data and this includes both 3g and wifi. Turn off 3g when not in use and you will see this wakelock going down. THe other one is nothing to worry

First, when you set the phone for the first time it does a lot of initial activity that may cause drainage.
In my case, I have 3 gmail.com accounts on my phone. I only need one of them to sync email, Picasa, contacts and calendars. On the other 2 I need only email. The phone was syncing everything on all accounts: in addition to the above also Google Photos, Play Magazines,Play Music, Internet, Keep and People Details.
As soon as I disabled all the unwanted syncing, things improved.

Exchange services draining battery fast

I have been using a N7100 Note 2 from Vodafone for about 4-5 weeks now and the battery life has been great. About 3-4 days ago I found out that Exchange services was the top consumer of my battery. This happened out of nowhere, without changing any setings. For example now I'm down to 3% battery. Phone was 14 hours on battery, one and a half hours screen on and one hour of phone calls. Top battery consumer is Exchange services with 38%. I searched other forums and other users are reporting same issue on different phones, but all of them running Jelly Bean. Has anybody else run into this issue? I was so much enjoing my battery life, but now I'm going crazy.

This happens on many platforms. iOS is not immune. Try delete and re-add the exchange account and let it re sync.

Yes, happens to me randomly. Mainly because the sync mode is push. Now I set to sync hourly and no issue.

I deleted the account and readded it and it does the same. What annoys me is that it worked right for 3-4 weeks than for no reason this behaviour started. I hope they will fix this bug. I don't want to limit the capabilities of the phone just to make it work right.

My battery eater was the latest Google Maps update,everything returned normal once uninstalled the it,have no issues with the Exchange Mail,its both setups are Push all along.

In my experience, turning of Calendar and Contacts sync helps.

I read in one of the thread that disabling Contacts helps. I've NOTE 3, and my battery drains so badly that I am so embarrassed that this NOTE 3 called to be beast comes only for 2-3 hours after full charge. I am heavy user and my Corporate Mail syncs everything.
I disabled Contacts and I could see improvement. My phone comes for 4-6 hours now. Disabling Calendar is not good since its so essential if you are using it to see your schedule everyday of your life.
Need your help to know if there are any other way to extend battery life?
Is it 4.3 android bug or even 4.4 KitKat is also facing the same issue? I didn't had this issue in NOTE 3 when it was 4.2.

The OS isn't always the reason for battery drain, many factors take into play.
How often you use the device.
Applications like widgets, email push.
Wi-Fi. If your not on it shut it down it else is always going to try to find a signal and drain battery.
Bluetooth. same with this.
Using the net.
Things like Google now, it's always running and trying to update info, shut it off of make intervals longer.
These are just some things to take into account, but at all use the phone different, and im not saying the OS doesn't drain but it solely isn't the only reason.
Hope this help.

I seem to be having the same problem. ..

Same here. With sync turned off, google now turned off, and most everything else that eats battery...
In the battery setting is shows that media is eating at least 25% battery.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

I'm having the same issue. I read that the media drain could be caused by bad media files, but I didn't have any issues before this weird.

In my experience when you first update to a new samsung rom, the media using the battery is your phone updating the picasa albums...which stinks because it also eats your data like crazy if you are not on wifi and forget to turn off sync until wifi is available.

I've noticed faster than normal battery drain as well on my device. Normally by 4:30pm I'd be at 40-50%. Now I'm in the 20-30% range.
I'm going to try factory defaulting it soon and run it for a day or two. OR I might not even do that and just go directly to Task's AOKP or CM10.

i dont have any issues with battery drain, but i would suggest a full restore after upgrade. dont restore using titanium, just install through playstore. then report back but i doubt it will be an issue

Before everyone jumps ship, may want to try a new kernel. KT and a few others should work on the new release. Just make sure you choose one that works on JB TW and not ASOP.

I have the same problem.. After JB update there is huge battery drain. With average usage it drains almost 100%. Before update with heavy usage I was going through the day.
Maybe I should try KT kernel I don't know. I wiped all after updated, nothing saved from ICS.

Same here,
It's seem the culprit is the android.process.media.
Each time i bootup,android.process.media is running for about 30 min, non-stop.
I already do a factory reset+sd formatting, but no succes.
With startup manager, i can block that process,but you need to be rooted .

I use the same settings as before i did'nt upgrade yet..i got it fully charge with no texting and calls the next 1hr its already 80%..i think i would try to cycle first my battery for 2 more days..then i'll see if it still have heavy drains..thanks for the response guyss.

Check out my overnight drian! from 1:30 to 10 the average drain is around 4% an hour, Losing about 20% overnight doing nothing.

I just got this phone the other day and immediately updated to jelly bean.Though I have nothing to compare it to my battery drain seems normal. I'm losing about 5% an hour but that is with some use (it's new so I'm playing with it a lot).
I did notice more drain the first day of use (may have been because I was using it a lot) and noticed maps was taking up quite a bit of the battery and I wasn't using it. So I uninstalled the updates for Maps and then re installed it. Battery drain seemed much better after that and now the maps app doesn't even show up in the battery report(before it was about 3rd and it seems kinda high on yours as well though you may be using it).

i'm noticing about the same battery consumption as the stock ICS rom. about 1~2% per hour when idle and sitting, 2~5% per hour listening to music over bluetooth with the screen off, and 5~10% per hour surfing the net and watching videos and stuff.

Well after doing probably 5 resets on my phone , it seems like everything is working fine . I was having issues with the battery drain ,internet not connecting, and phone calls taking 2 minutes to connect.

I was having issues with high battery usage as well after updating to JB.
I froze most every app and widget associated with AT&T and Samsung (with the exception of AllShare) and flashed KT747 kernel and set governor to ktoonservative (default settings).
I am really never a heavy user during the day, but with the same usage I had on ICS, I average 15.5 hours (with the phone at approx 15% when I shut it off to charge) - screen on time between 2.5 and 3 hours; call time between 45 min and 1.5 hrs; media (which seems to be a big battery hog) only about 6 minutes. I use bluetooth exclusively, so that radio is on all the time the phone is on. I keep sync and background data on, but only turn mobile data on as needed.

[Q] Battery Drain Issue

I am trying to troubleshoot my battery drain issue so I have been inserting a fully charged battery into my Note 2 just before bed.
Stock 4.1.2 ROM
Rooted
Night 1
Before bed: 100% battery, airplane mode
Wake up 7.5 hours later: 100% battery life
Night 2
Before bed: 100% battery, WiFi connected, background sync enabled
Wake up 7.6 hours later: 54% battery life
I have Greenify and BetterBatteryStats and still can't figure out what is sucking down the power.
Sync Interval:
Twitter: 4 hour
Facebook: 30 min
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Any help would be appreciated!

I think you really have nearly answered your own question - it's the syncing that's killing your battery. FB is notoriously bad at draining a battery all on its own and the others may be bad too. The dead giveaway is the phone isn't deep sleeping anymore with sync on. Keep up your experiments but freeze each app/process in turn to see how bad each one is and you'll find out. No need to leave it over night - an hour or two should be plenty to find out. In fact, if you have your phone set for max battery life, it should go into deep sleep within minutes of locking it. Personally I only sync manually and that's including email - but I'm not too plugged in so I don't mind checking a couple times a day manually. It does mean killer battery life though! Really any process that is constantly waking up your phone will do the same thing as fb - Google Now with location history on is another bad one.

I use fb and I get no battery drain from it

Still unsure about which app is the main culprit. Facebook seems like it could be the biggest problem. Attached is my dump from BBS (BetterBatteryStats) I tried the same thing as the night before except I did the following
Facebook Sync: Never
Twitter Sync: Never
Touchdown HD: Push (exchange)
Reddit News: 12 hours
Night 3:
100% battery before bed, background sync enabled.
52% Battery by wake up.
NOTE: 10076 (Wifi) (com.android.vending.Google Play Store): 86.0 MBytes 95.3% was my apps updating just after boot.After all apps were done updating, I put the phone to sleep until morning.
Things I am going trying.
Freeze Samsung Push
Freeze ChatOn
Greenify Facebook

You need to understand that virtually any app that has the ability to poll your phone and push updates to it automatically without you visibly seeing it is going to drain your battery. This includes:
1. GPS
2. Having your data on in general (networks push packets to each other to stay within protocols regardless)
3. Google Accounts (syncs your calender, contacts, people, etc.)
4. Google Now
5. Mail
etc, etc.

I know this is a little off subject but will face book still drain Battery even if you have location off and sync off?

Facebook Messenger was an issue. It kept waking up my device. I have been doing some testing though and have had almost no luck until tonight.
I disabled WiFi before bed with 100% battery. 7 hours later, 91% battery.
I need to find which apps are using WiFi so heavily.

I have been using Greenify the whole time. Currently, it looks like when on WiFi apps are going crazy with connecting and waking up the phone. On Mobile, I got much better battery life.

Try backing up all ur data on internal and SD card.. Then do a complete fresh install.
