Weird battery drain recently

Hey guys.
I have had a Nexus 7 since the end of July and I love it! However, recently I have been experiencing a weird problem with my battery. Normally, after a full charge I can get about 6 full days in just standby or about 5 if I use it for a considerable amount of time. What has happened recently is that my Nexus has dropped the battery percentage by a lot at completely random times. Like for instance, Friday night it was at about 15% when I left it. Now normally it'll only drain a few percentage points while in standby. I came home about 4 hours later to find it completely dead. That has never happened before. It gets weirder. Last night I went to bed with it at about 85% remaining. I woke up about 6 hours later and was surprised to see that it drained to 55% in just standby! Then after it drains a large amount, it goes back to normal standby behavior. (It is at 53% as I write this)
Any help would be greatly appreciated. Thanks!

Have you checked which apps are running in the background? Did you install any new apps around the time your issues began?

Sorry for the late reply. I have not installed anything new. I will see if it happens again. So far, it has not.
Thanks!

[Q] Battery Draining 25% overnight.

My Battery drained from 100% (it was fully charged, then I unplugged it and locked it) to 75% overnight.
What are some likely causes of this?

I noticed you have no signal. Constantly searching for a signal will drain the battery...
I've only had my N4 for a few days but the battery life has been good so far. A couple of brief observations...
1) On wifi only overnight (no SIM as I just got it and didn't have a micro yet) for 7+ hours. ZERO % drain...
2) On LTE (2-3 bars) for the past 3 hours. I left the phone and came back later. ZERO % drain...
Gmail is push, no GPS or BT. Only core apps running. I don't normally have anything in the back ground outside of lightflow...

Download GSam battery monitor

I noticed this also. I never had that much drain with my Galaxy Nexus.

I went out to lunch. Sent a few texts with google voice and looked up some random food articles on wiki for a few minutes. I was gone for 1-1.5 hours and now my battery is down to 47% from 75% this morning.
I'm going to download GSam and see what I get from there.
Edit: Installed GSam.
Attaching results from it.

Charge it fully tonight, unplug it in the morning, and then post your GSam results tomorrow night after a day of usage.

Mine has started loosing charge overnight too.
It won't turn of wifi when asleep either. Since I activated Google Now.
Mine lost 5%in 4hours overnight. Nothing running apart from mail and now notifications.

Your android OS usage is terribly high. That's my first suspect.

My android OS usage is very high as well... sometimes higher than the screen. I'm gonna try turning off google now to see if that does anything but other than that I have no idea what would be causing that...

The screenshots show app usage as being 50%+.. It is probably a rogue app you have running in the background.

As I said before, I believe it's some Google apps, I deleted a bunch of Google apps I don't use. My phone sleeps like a baby now. Overnight it only went down 2%.

I had the same issue for a couple of days. I would wake up to my phone only having 65% charge and the device would be rather warm. In my situation, I found that the charger was faulty. I noticed at times it would cause the phone to flicker back and forth from charging to in use. Lucky for me, I don't sleep well at night and I found the issue after my phone had been plugged in for 5 hours in the middle of the night. With that said, I also noticed the charger would make a high pitched hum/hiss. I swapped my charger out for my old Iphone 4 charger and I haven't had an issue.

Nearly a full day's results.
I left my phone charging from night until morning. I unplugged my phone sometime around 10-11am and I stepped out around 12:30.
It's 5:52 pm now.
I was out from around 12:30 to around 5ish. At around 5 my phone had 50-56% battery left. My friend's Iphone 5 had 75% left. Aside from my friend using his iphone as a GPS to navigate in the car (around 20 minutes) - we had roughly the same phone usage (by my estimate of course), we were at same locations and both of us are on the same network.
To be frank, I don't understand why my friend had more battery life than I did considering he was using gps. I do feel like there is something draining my phone battery.
My screen light settings are on automatic.
I've attached GSam and my list of applications.
From about 5 to now (5:52):
After a bit of surfing, installing 1 application to list my apps, emailing that app list to myself screenshotting the relevant data and emailing those screenshots to myself over wifi. I'm now down to 39%

Q. battery question

Is anyone experiencing weird issues with battery before recharging? i had 2 days phone on batt and 3hrs screen on. It was at 53 % before i decided to charge. I fully charged it and now im losing 10% every hour even with phone on idle. Its weird cause every other charge will last a long time.

Yeah, I'm still stock on this phone and I'm getting inconsistent battery life. I usually charge every night, so I'm running about 16-17 hours per day. Almost identical usage each day but one day I'll plug in with 45-50% remaining and the next it will be dead when i plug in. Very odd. I'm going to root this thing just so I can get rid of the bloat apps. Well, that may not be the only reason I root. I may be compelled to put some AOSP on this and see how it rocks it.

well i don`t really recommend to ROOT stock rom, it caused for me a battery drain ! also KitKat known for drain issue even on Pure android on Nexus 5. I don`t really know a fix but i`d give u some tip and it might help
1. Re-flash D80020c
2. After re-flash do a factory reset
3. Don`t root or mod your OS
4. Turn off Sync or Location Service (or set to battery saver mode)
i did those steps and i have 34 hour on battery:
3 Hour screen on time (and about 30-40 min gaming in this 3 hour)
Left about 49%
i hope i helped a little

Potential solutions:
Have a look in Settings > General > Battery and see what seems to be using the most power. You could have a problem app that’s using GPS or trying to update frequently. If you can identify the culprit then you can remove it.
There’s a slim chance you have a faulty handset. If adjusting your usage and tweaking settings doesn’t’ result in any improvement then take your LG G2 back to the retailer or carrier and get a replacement.

I always have location turned off with all bloatware rwmoved. I honestly think you have to drain it to about 20% then charge. Cause i never have problems when i do that. Gonna try and drain it out again and recharge and see what happens then.

Are you having issues on KitKat out jellybean?

Its kitkat,it says rooted d80020c in my signature. Well here is my latest results. Left it on overnight and was at 53% with data off. Checked it this morning and everything was back to normal again no battery drain or low estimated battery times.weird cause i charged it around this percentage. I think you have to take it down to at least 20 before charging will find out later today when i charge.

well i really not heard about Deep sleep drain but while idle it`s drains bit faster then JB, with jb i could get max 40 hour and about 6hr screen on time and + 10-15% battery while on KK i can get 42 hour but about 5 hr and 45 min screen on time with 0% battery it`s seems a bit problem for 4.4.2 i think Google will fix it and hopefull we`ll get new update from AT&T if this prob will fixed
P.S i saw that if battery at 100%, overnight it won`t fall to 99 but while battery is on below 100% it drains about 1-2 % overnight is that a known prob?

2% overnight is pretty good, given that it's on WIFI I'm assuming?
I lost 25% overnight last night when I was off WIFI, so I factory resetted mine.

Took it down to 20% and discharged and its fine. Im guessing its a bug,but, easy fix just take the battery down to 20% or lower before charging

Official Idol 3 Battery Thread

I figured we could get this started, so we can start to post stats and screenshots once you finish initial setup/installation and get into regular daily use.

went to bed last night with the idol at 75%. woke up and it was still at 75% to my surprise. (and I did the update right out of the box, for anyone wondering.)

Seem to be great, can't wait fort mine

The phone arrived at around 40-45%. Spent around 2 hrs updating/installing/customizing stuff which was enough to drop the battery to 15%. Mind you that almost all factory settings were still there like vibrate on almost everything and sound on almost everything. Battery was fully charged rather quickly. I had around an hour of SoT before going to bed with around 80-75%. I woke up to a 70% battery after 10 hrs ( I slept in).
I think battery on mine could be improved by turning down the Google Now settings. It is the most power hungry in the battery stats at 9%. Oddly, the location icon is almost always on even if I'm not doing any location related tasks. I'm hoping to look into this more and fully test the battery tomorrow when I go to Sta. Cruz.

The Idol 3 just won't die! I'm using it around the house. Haven't actually put a sim card in it yet, so that might explain some of the great battery life that I've been getting. But this is the first full power cycle after getting it on Saturday. Auto brightness, full sync. I had to stop at 11% so I could do a charge test today. But I have no doubt that this 11% could have gotten me another hour of screen on time. Tons of streaming Sirius too over the front facing speakers (like 5 hours). Very impressed so far. The price is justified by the screen and the speakers alone in my opinion. Add great battery life to the mix and it's a pretty special device IMO.

Charging time is done. Used an Anker 2.0 Quick Charge (just to make sure it got the maximum it could handle). Went from 11% to 100% in 2 hours and 28 minutes. Not too shabby considering how long it holds on to the charge.

Bettery drain while on wifi
Hi, I have bad battery drain while on wifi. What I noticed is that cell signal goes from empty to full while unlocking screen. It goes up to 10% per hour. But when I was away from home for few hours on lte, it was very minimal. Any ideas? Software bug or maybe some app is causing that? Thanks!

Did you do the update that appeared as soon as you turned it on out of the box? I had the phone on wifi all weekend (it never left the house) and the battery life was amazing. See my posts above. And I did the update first thing when I got mine.

Yeah, that's the first thing I did. Today I'm on LTE all day long and battery is amazing. But when on Wi-Fi my cell signal goes to emergency back and forth. Maybe my phone is a lemon

I should have checked the battery life before loading all my apps but I forgot. During sleep hours I only have the wifi, auto sync and phone antenna enabled. I also either use the adaptive brighness at 50% or have the brightness set to about 20% with adaptive disabled. The first night I checked the battery overnight usage it was down 16% in 10 hours. That was also runny 3 apps on the notification area. The drain comes to 1.6% per hour. The next night I removed the 3 apps that run in the notification area and the drain was 10% in 8 hours, which comes to 1.25% per hour. That's better than my old phone but I still think it's too high. No apps are open in the recent apps screen.
Is anyone getting better or worse? I would like to compare my battery drain with everyone else.
Edit: I did disable Wifi Network Notification and Scanning Always Available. I'm not sure what kind of effect they have on the battery though.

Did you wipe your cache after the OTA update? I remember my Nexus 4 and Nexus 7 had temporary issues with battery life that were cleared up by a wiped cache/factory reset.

I have the HTC m8 and g3, had the m9...
I think you have a problem with Google apps...Because with the m8 I had 7 hours screen on time in 24 hours, 6 hours with the m9, 5 hours with the g3...
And every reviewer criticizes the bad battery life of the g3 vs the very good battery life of the idol[emoji2]

Yesterday was my first battery experience day. I have to say it turned out pretty good. I got roughly 16hrs from 100% charge down to 15% charge. I got a battery warning when i was headed to bed. Throughout the day, here's a list of the things I did in general to give a scope on usage:
* I had all services on, LTE, Wifi, Bluetooth, GPS (High precision)
* i used it to read a kindle book. I had my screen set at about 80% brightness the whole day.
* I have "Automatic" app which uses the phone GPS to track my drives to and From work.
* I ran with Runkeeper GPS
* also streamed music to and from work on my wohle commute (roughly 45 minutes).
* Then throughout the day did normal checking of various apps and websites, and notifications.
* In general during the work day I don't use it much from 9-5, except maybe to check it once an hour , and read a little.
Previously on my Nexus 4, I would have had to have it charging all the way to work. Then charging all the way home, and many times it wouldn't make it to bed time without another charge. With the Idol 3, i didn't put it on a charger once throughout the whole day. Pretty awesome.

This is my second full day. I expect that it will improve after a few cycles but I have absolutely nothing to complain about. WiFi on most of the day. 2 Gmail accounts syncing, Bluetooth on, display only at 50%, (not to save battery, but just because I don't need it any higher)
I have a few small hiccups with the DTTW but it isn't terrible.
P.S. This blows away my Zenfone 2 in battery life.

Battery life is ridiculously good. Charging my phone is no longer a pressing issue for me nowadays. Personally, I am indoors most of the day so I have set my screen brightness to 0% and it is perfectly fine. When I am outdoors, I will pump up the brightness to 100% which increases the battery consumption noticeably.
I've had the phone for a week and a half and still have never gotten down low enough for Battery Saver mode to kick in.

For me battery hold amount of charge EOD.
100% in morning around 10 AM.
1. wifi/4g ON all the time.
2. GPS during commute to work and vice-versa
3. Music app for 1.5-2 hrs.
4. played game for 2 hrs.
5. normal browsing.
Now @ 7 PM : still 45% left.

For those still unhappy with the battery life here are a few free apps that can help:
https://play.google.com/store/apps/details?id=org.gpo.greenpower&hl=en [ Battery saver...does things like only keep wifi on periodically to check for hotspots and only turn on bluetooth when charging etc ]
https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite&hl=en [ Adjust screen brightness based on light levels ]
https://play.google.com/store/apps/details?id=com.keyes.screebl.classic [ Keeps screen on when phone is held in upright position but quickly turns screen off when phone is placed flat ]
I use the pay versions of these and consider them worthwhile.

Does anyone know how the automatic brightness works or if its even useful to have it on

9.0.11 Battery Drain

Here are the stats:
Verizon
9.0.11
Not rooted
I updated yesterday and the battery drain is a crapshow. Fully charged since 9 am, and its 1:30 now and I'm 84%, with a 6 min screen on time.
I literally touched my phone 10ish just to check messages and text a few people.

Install this: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
Then do some proper measurements. With just your explanation we can't do much ...

Install a kernel. I get 10 hrs screen time with radioactive

Not seeing a difference with 9.0.11 on mine over previous versions.
As for suggesting installing a kernel on a non rooted phone :-/

I also have the same problem, when I was in 9.0.7 I was able to get as much as 13hours screen on time in 48 hours or 7 hours in 6 days. Amazing battery life. Updated yesterday and the phone cannot compare. It is draining as much as 10% over night.
I am stock, no root.

Yeah they fcked something up.
Also beta2 has issues with standby drain...

I've seen this on and off. Some nights latent drain is 3%, others it is 13% with almost no app usage monitored.
Maybe cellular draw? Tonight I'm going into airplane mode with WiFi on and see what happens.

Do you have any social media apps? 7 hrs of sot in 6 days without a charge is nuts even that 13 hours of SOT in 48 hrs is impressive. I've been nowhere near those numbers with my 6t

no social media apps whatsoever besides viber and skype (but these do not count as facebook and the others) but even these are battery optimized.
phone is draining a lot now, not sure why. all is the same as before the update.

I agree. 9.011 is definitely draining battery faster than 9.07

Ya it must only be possible to get that good of sot without those apps. Do you use any Google apps, I know that is another battery drainer which decreases maximum sot potential.

Move to beta 2

Last night I let my phone on .11 sit idle for 9 hours in airplane mode with WiFi on. It drained 7 % over this time which is more than I used to see on build .07 with cell service on.
The odd thing is that apps are reporting very low usage (in total less than 1% of the battery overnight) so I need to look deeper. Phone is >95% deep sleep overnight.
Some nights low drain, some nights high, no pattern I have found.

.11 overnight (8 hours) on mine is currently draining around 3% over that period with everything on as normal.

I have experienced the same. But, after having .11 installed over a week now suddenly my SOT has improved to same level I had with .07.
I have read somewhere that since it is software controlled the system has to "learn" the most efficient way to handle, e g the option "Smart battery" (have that always on), and that process should take approx 1 week.
I do not know what's happens when I updated to a newer version. Maybe the system has to "relearn" again? My device is rooted, so I receive the full version on every update (no incremental) - maybe that also have an impact on the battery performance.
I do not say there lays any proof in this "theory", but my battery life is very good again (around 13 hours SOT/48 hours total). So in case you have updated recently, be patient for some extra days.

If I knew about this I would have stayed with 9.0.7. Let's hope they fix this soon.

Rebooted about an hour before going to bed, let phone charge to 100%. Unplugged. 9 hours later it was still at 98%. This was the first reboot in a while. Just a data point; previous night even with cellular off it lost lots more than that.

Suggest you to Wipe Cache from Recovery after a OTA update.

No issues here with .11
