Google Now Widget causes significant battery drain - Nexus 7 (2013) General

Just wanted to share my experience.
Found my N7 battery was draining significantly while it was sleeping. As an example, I would lose over 10% overnight with the N7 off the charger. Hence I was having to recharge my N7 every 2 days, even with little use.
After Googling the problem, I tried various things like setting WiFi to "never" be on while sleeping (advanced setting), turning off location reporting within the Google account, turning off location history, etc.. All very common suggestions but none of them helped me.
I then removed the Google Now Widget and Voila!
I have now re-enabled location services and Google Now is still available by swiping up from the Home button. Battery drain while sleeping is back to just 1-2% overnight.

[Q] Battery drain from Android OS, suspend, and event/0

I know this issue has been posted in forums for other devices, but I haven't seen anything about it for NC. I did try to search the NC forums but couldn't find anything that seemed to address this problem.
I am using MIUI 1.7.22. I have noticed significant battery drain due to Android OS (in battery stats), suspend (in the systempanel app), and event/o (also in systempanel). I have disabled auto-sync and any apps that appear to be likely culprits (those that might attempt to download data). This problem seems to appear with wifi on or off, and when on, I have tried both setting it to never turn off and to turn off when the screen is off. Initially I was experiencing battery drain due to cell standby, which I took care of by disabling the telephony provider, phone, and mms apks. I know many don't believe this has an effect, but I did it anyway. The cell standby drain is gone, but now I'm fighting the drain due to these other factors. Has anyone found a fix for this?
After scouting around for info, I have tried some suggestions seen elsewhere: rebooting and wiping dalvik cache. So far today I haven't had any Android OS, etc. issues. Standby life with screen off is as it should be (for now and hopefully forever)--very slow battery drain.
This is with wifi set to never shut off, which I prefer.
Suspend etc. came back last night although not as extreme as before. Hopefully some other folks will have things to add to this thread. I will continue posting progress info as I learn more about this.
From the code.google.com forums:
Confirm heavy battery drain with enabled Location & Security -> Use wireless networks / Use GPS satellites. I've disable both options and now my battery life is normal.
With enabled "Location & Security" options battery eaten by "Android OS" process (about 40-55%).
I will try this and report back.
Disabling WIFI and GPS in location/security had no effect. There appears to be a google process that prevents the system from sleeping.
I was still experiencing random battery drain due to Android OS, suspend, event/0 after switching to cm7. One suggestion I read was to disable calendar sync, as this appears to be a runaway process that attempts to connect to the server constantly without allowing the device to sleep. Doing this allowed me to get through the night with very little drain and the Android OS, etc. processes were finally behaving (within normal limits).
I'm not sure if anyone is reading this thread but I will continue to update until I figure out the solution, as I imagine this problem will become more noticeable to others who are equally frustrated with this issue.
Having same problems on my galaxy s2. Lots of people have this problem and think it's a problem with the os. What os version are you using?

Right now I'm using cm7 (2.3.5) but I was using MIUI before. Turning off calendar sync has worked well so far.
I had bad battery drain in the past and no deep sleep. but what worked for me was not to use any live wall paper. this fixed my deep sleep issues. for the battery drain, re-set your battery stats and re boot a couple of times for the stats to settle down. also check google map and latitude. in latitude just log out. un-checking sync in my yahoo email app also helped with my battery drain. my wifi is set at, off with screen. I went from 20 -30% drain in 7hrs to now 1-3% in 7hrs
I hope any of this info can help

Thank you, boxcar. I had tried all of those things (froze live wallpaper, reset battery stats, reboot, froze maps and latitude) but the only thing that worked for me was unchecking the box for calendar sync. Email sync and wifi appear to be non-issues--no difference between off or on. Evidently this google calendar sync bug is a known issue (that very few people seem to know about!). I hope google will fix this soon.
I also have same problem on my Galaxy S2. These two(events/0, suspend) drain many battery, 14% one night, without WIFI, GPS, Bluetooth.
I'll keep on tracing this issue, and share the result in this thread.

Turning off autosync seems to help the most (although setting WIFI to turn off when the screen turns off appears to help, as well). I tried using an autosync toggle but just turning it on at all seemed to result in a gradual creeping up of the Android OS, etc. problems. Manual sync of calendar and perhaps gmail and contacts seems to be the way to go. For some reason, exchange mail set to push results in no problems. The other trick I've found is to go to applications, then calendar and calendar storage, and force stop, delete cache, and THEN manual sync of calendar (reboot, recovery, wipe dalvik, fix permissions are good ideas, too). When I flash nightlies, I go through this process and the offending processes work as they should. If I don't, problems appear sooner or later.
I've had my nook on for 9 hours now, WIFI on (off with screen off) and 30 minutes of display on time. I've lost 9%, so I think I'm on the right track. This is how it should work, I.think. Of course, the results SHOULD be the same with autosync on, but manual sync for good battery life is an acceptable small tradeoff in my opinion.

For the noobs in the audience, how exactly does one turn off autosync? Where is it located?
Thanks in advance.

Menu, settings, accounts and sync (I leave background data checked).
I found part of the root cause, maybe some old application - can work on new version, but drain many battery. Today I uninstalled the 'Android photo widget', then only 1% battery has been drained within 2 hours when standby. Not totally solved the issue, but seems OK.
I guess you can also try this, find another 'bad' application which drains your battery.
Well guys, I'm not sure if I'm the last Nook Color user to continue fighting with this super annoying headache (I know SGS2 users are, too), but I think I'm on to something. I thought calendar sync was the culprit (and perhaps it was), but the Android OS drain (featuring nemeses suspend and event/0) would not go away and the arrival of this problem continued to be (apparently) random. I had an idea that, if the calendar sync kept alternating between suspend and event/0, perhaps this was due to old events that caused the sync process to continue longer than it would normally. So, based on this idea and logic, I changed my exchange e-mail account settings to sync email from the last month rather than to sync all mail. Looking at my work e-mail history, I realized I had e-mails in various folders and sent mail from as far back as 2001! Although it's nice to be able to access all e-mail history, perhaps the polling services were constantly monitoring the activity of super old emails and folders, which caused the suspend and event/0 processes to flip out. I don't know if this is the way Android actually works but it seemed logical to me. Well, for the last 24 hours, I have intermittently checked my cpu activity through systempanel, and what do you know, when the device is not being used, suspend and event/0 work as they are supposed to and Android OS stays low in the battery % list. PLEASE let this be the fix! I know there are other factors that contribute to the acting out of these processes, but on a stripped down device with no autosync or widgets and no out of control services identified in systempanel or watchdog, there can't be many other explanations. I'm curious if others with this problem have similar settings on their email accounts. In all the forums on different sites (and I've read a ton of them), I've never seen anything like this mentioned.

Please vote there, and, may be, Google will fix it.
For those still following this thread, here's a tip. Use Gemini app manager (in the market). This has been one of the best tools I've found for managing wakelock issues and battery drain during standby. It allows you to identify apps that start up on their own (more than you think) and prevent them from starting randomly. In my experience this has been a huge cause of the standby drain problem showing up as Android OS, suspend, and event/0 in battery monitors. I'm currently sitting on 81% battery remaining with over 1 hour of screen time after 21 hours since my last charge. I know it's not a lot of usage but it's the standby time that's fantastic.

I've a Galaxy S2. Tried everything, except disable autosync. Was losing 30-40% battery at night. So far since turning off google sync I'm getting about <1% battery use an hour. Will see if it continues. Thanks.

Stopping services from Task Manager helps battery

Recently been getting battery drain while on Idle. This drain I tend to notice at night. My phone can idle duriing the day but does not drain battery.
I recently disabled Android system IQ agent .. and it seems to have helped at night after rebooting and stopping that service.
I also noticed when you go to task manager and go to settings there is an option to stop services. I checked Facebook (51 services wth). Google Play Books , Magazines, and Movies\TV. I also checked Google play services (65 services).
Believe it or not my phone seems to be running fine and my battery life is a lot better.
Now I set my brightness at 47% (not auto), Google Now is enabled with Wifi and mobile location. Google backup is enabled (most are unchecked including app data) Email is manual sync.
Just thought I"d pass this along. YMMV.
Thanks for your tips. I noticed random battery drain these few days, no idea what it is, high battery drain when idle, and it happens randomly. Will try and report back. Thanks

[EXTREME BATTERY DRAIN OVERNIGHT] Possible fix and reasons

Hello
PROBLEM
Recently I have been facing issues with my nexus overnight battery drain. The battery drain is quite shocking (30-35% overnight). The irony is that using my nexus over two-three hours drains less battery than keeping it on overnight in deep sleep mode.
BEST SETTINGS FOR CRAZY BATTERY SCREEN TIME
I'm using 4.4.2 with elementalx kernel(2.12) with 800 undervolt, 1350ghz processor with 400 GPU.
I disable all double tap to wake up, slide to sleep features with all default settings except I use battery life extender at 4100mah (83-85% charge).
With these settings I have extremely good screen time over 6+ hours (I never calculated it but watching two movies of 4 hours only drain 32-38:victory:% battery with software decoder using headphones with MX player pro.
The reason for sticking with 4.4.2 is that on 4.4.3/4.4.4 the battery life doesn't reprpduce same for me.Also I face some ghost touches on latter updates.
On dalvik, I experience no problems on 4.4 to 4.4.2 but sometimes ghost touches on art which solve after a restart. In safe mode, there are no ghost touches in art!
Currently I'm on art.
APPS AND SETTINGS HELPING ME WITH GREAT BATTERY
I have greenify, wake lock detecter with Google search frozen(using titanium backup); location turned off, no NFC , no Bluetooth, WiFi only when required, sync on only for contacts, keep, chrome and I am using two gmail accounts.
All other apps like quick office, maps, earth, YouTube, newsletter, currents etc have been disabled! I don't leave WiFi on overnight!
All applications that require root are greenified/frozen until if required which is rare so I refreeze them afterwards.
All applications identified by wake lock detector are greenified! (Not using xposed framework to greenify system apps)
I use "show touches" on my device in dev options to keep track of ghost touches etc!
IRONY :
The irony is, android system and android OS drain about 9+12 % of my overall battery in deep sleep with my screen taking only 27% with over 13 hours time.
This means Google services are draining battery but I can't point out which on!
WHAT I'M THINKING OF DOING
I guess I'll update my Google play services and update with results! Version 4.4.52 is a battery killer !
Tried version 5

[Q] Google Services battery drain anyone?

I'm running stock/rooted kitkat and for the last few days I have had dramatic battery drain. I go from fully changed to 10% in less than 4 hours. Has anyone else noticed this lately?
I had this as well. I had to disable location services to get my phone to actually go to sleep.
Sent from my AOSP on Mako using XDA Free mobile app
disabling location services and trying that. thanks
I've had awful battery since i upgraded to 5.0 and Google services are killing the battery. I'll try location services. Will update.
It's definitely not a problem with Location Services. My location is completely turned off 99% (since always) of the time and I also have that topping my battery consumption. Even though, my phone has been deep sleeping without major problems. There's an unknown wakelock that is slowly draining the battery, but anyway I've been getting 4h of SOT everyday without making any sacrifices. If somebody finds out what's the root cause, keep me posted, please.
I've been occasionally getting this for a few weeks too.
If I turn off location, the problem continues for a day or so but then goes away.
This morning I took the phone off charger first thing. I restarted and didn't open screen for two hours. When I checked battery usage it was down 80% and the big consumer was Media and SDcard. Anyone see this before?
It just occurred to me that I may have a corrupt file on internal storage. I'm going to back everything up and start deleting.
Well..I did a factory reset and I still have a major battery drain. It has to be some rogue app but I haven't installed "new" apps lately. Plenty of updates though.

Battery Drain | Idle

My Essential PH 1 is draining a lot.
Phone idle is taking most power with approximately 17%. Screenshots attached.
Can you please advise if this is normal and ways to minimize battery drain ?

Are you showing off? because those are amazing numbers. You're on track for 35 hours! I get around 26. Your bigger killer is What's App, but that's expected for a Facebook app. 17% for idle means your phone is on and doing nothing 17% of the time.

Nope I am not showing off, I think i am having huge drains when I am asleep. Most of the time in that graph is idle time so i am thinking it should be better ?
Again I moved recently to droid from iOS so i am unsure of the droid power management baselines.

Cool. I didn't mean to seem mean, but those are good numbers. If your phone is on, and you have push notifications (pretty much every social media app, phone, sms, etc.) you're going to have drain. Even if the phone was off, the battery would drain somewhat. But you have What's App and other chat apps, so that'll use battery, even if your asleep, the phone isn't. It's the only way you would be able to receive calls, text, updates, etc.
That 17% looks steep, but it's all relative to a small screen. over the span of 20 hours and you still have almost 50% battery, especially with "free" apps that are basically advertising engines pushing ads at your every minute. Having Phone Idle at the top is not a bad thing, it just means you don't use your phone as much as you use What's App.
1% per hour is good, better than our S8 even
I had enabled "Cellular data always active" and it chewed through my battery life. I turned it off and can now last 1.5 days on a charge.
My phone is draining 12% overnight. And phone idle is top of the list. What does this phone idle do? There was a random night where the phone only dropped 1%. But most nights, it's draining around 10% with phone idle at the top.
Update: setting wifi to not stay on while phone is sleeping seems to fix the drain issue.

Does disabling it affect receiving messages that rely on mobile data such as WhatsApp?
Where is the "cellular data always active" setting? I don't see it. Have not updated to run Oreo.
My battery was dropping from 95% to 5% overnight. Did a factory reset which helped, but I'm still losing 17-20% overnight. Seems odd to me on a brand new phone, but I have never owned an Android before. I have blocked notifications and location services from nearly all of my apps. Any advice other than what has already been posted?
If your losing that much overnight it's probably a bad app.
I don't use it, but have read that the Facebook messenger is good for that. As in eating up a battery overnight.

I can promise you that that's not normal, especially for this phone. Overnight battery loss is minimal, 15 hours of idle with a 10% drain is what I'm getting. That's pretty amazing. I'd check your apps and ask the general android forums for advice. I also bet there is a rogue app draining you juice. chat and social media apps with all their pushed content and friend updates are huge battery killers.
Install accu battery ,charger to full last thing at night ,don't touch through night ,then see what's draining battery ,mine drains by about 2/3% through 8/9 hrs at night

It's under developer options settings. I have mine always active without draining my battery noticeable.
The social media apps such as snapchat, facebook, twitter, etc... are the ones draining your battery while your phone is idle so you need to disable their background data running.

The option to Cellular Data Always Active is on the Developer Hidden Menu. If you have it enabled you should be able to turn it off.
Thanks to all for the replies. I thought that restoring factory settings had helped somewhat, but it turns out not to have. Battery has just depleted from 100% to 67% in 3 hours while the phone has sat idle.
The only social media apps I have installed are FB and Whatapp. Notifications for both are turned off. Location services for all apps are also off. The only apps I have installed have been download from the Play Store and have run on my previous phones without causing any trouble. Those who replied all suspect a bad app, so I have installed ACCU Battery as suggested to see if I can nail it down.
Thanks again for the responses.
Try this for one night. Right before bed....
1. Turn OFF WiFi
2. Reboot phone
3. Leave WiFi off after reboot
There is a bug in Google Play Services that affects many people on many different phone types since the November updates.
When on wifi, in certain circumstances (many theories on what the actually trigger is) it will cause Google Play Services to run non stop on certain WiFi networks causing huge battery drain.
In this particular scenario, turning off Wifi does not stop the battery drain. The phone has to be reboot.
I don't know if that is what you are experiencing, as you didn't say if it was an app or system taking so much battery, but I thought I would mention it in case it helps.

Why don't you look in settings/battery and see what is using the highest percentage of the battery?
Have looked in Settings/Battery, but am not seeing anything there that diagnoses the problem to my understanding. Highest use shown is Chrome (4%), then Screen (4%) then Google Play services (3%). ACCU Battery app shows the same. Battery is still losing 10-12% of its charge per hour while the phone is idle.
Have sent a message to Essential support to ask if they know anything about a bug in Google Play services causing battery drain. They have so far only suggested rebooting to safe mode and doing the reset to factory settings. Hasn't helped.
Will try shutting wifi off, rebooting and leaving wifi off tonight as suggested. Not really sure where to go from there even if that does save the battery, as a phone that has its battery drained just by being on wifi is useless to me.
If turning off WiFi and rebooting helps reduce system cpu usage, it is a bug in the software and not the phone. I can reproduce that specific issue on my pixel 2 and Samsung Galaxy s8, too....
If the CPU usage isn't from system, though, or turning WiFi off and rebooting doesn't help then you obviously have a completely different issue and need to troubleshoot further.
Sent from my Pixel 2 using Tapatalk
Update:. Nothing Essential support has suggested has helped. Battery is draining to zero overnight while phone is idle both when connected to wifi and when not.
Upon learning that I had purchased the phone at a Telus store in Canada, Essential have said that they can't help me further and have referred me to the store for assistance. I'm disappointed in the lack of support from Essential.
