Hi all,
New to the forum. Sorry if somebody has already posted something similar. Tried to search but could not find any.
The reason I am here:
Yesterday night before going to the bed, my phone battery was >80% charged. In the morning I found my phone switched off. I had to restart the phone using the power button. The battery was at about 40% down when I turned it on.
I dont use the phone much through out the day, so it uses around 20% in a day(morning to night).
There is nothing unusual that I can see in the battery usage stats. Attaching screen shots for reference.
The graph shows a sudden decrease in the battery power. I am not sure if any sofware can consume so much of power in such a short time, unless there is a hardware issue or the battery readings themselves are incorrect.
This is the third time in the last 5 days that I found my phone powered off in the morning with a sudden fall in battery power.
I am using the stock android 4.2.2 with all the updates applied.
Can anybody please help me understand whats going on?
When it drops straight down it signals either a reboot or a power off. Something is causing your phone to turn off (obviously), it isn't just a battery drain issue. That said, it shouldn't drop that much if it is off.

Thanks josh, is there a way to debug whats trigerring the shutdown? What worries me is the sudden power drop? Could this be a harware issue?
There might be some safety mechanism which will shutdown the phone in case it finds the battery current is extremely high. I am just guessing.

The battery % indicator isn't completely accurate so whenever you reboot your device it tends to show as a lower value than before you rebooted it. I find that whenever I reboot my device the instant drop is then offset by a slower than normal drain as shown by the indicator. Obviously the drain is no different but this is just what the indicator is showing.
I wouldn't worry about the drop itself so much, just what has caused the reboot. I can't help you there so maybe someone else has an idea on how to figure that out, good luck!
Try flashing the stock image again; efrant's guide in my signature is the best & most educational way to go about it..
P.S. overheating will shut the phone down. Maybe some rogue app misbehaving? Long shot but could be it. Search for betterbatterystats here in xda, see if some app produces some crazy wakelocks. If not, go back to the top..

You can monitor with betterbatterystats.
And if you are rooted you can check the root features in advanced settings to see any alarm that occur.
This will help you debug the problem.

I wouldnt be worried about the battery drain.. That is usual for your situation as you hardly use your phone, the battery reading isnt always accurate and is most accurate after a reboot.
If your reallt worried. Reflash stock images fromm Google. Don't use toolkits and learn something about fastboot and your phone.

So after reading everywhere on the forums how amazing the Atrix's battery life is, I took a look into my phone to see why mine was so shoddy. Turns out that when I type *#*#INFO#*#* on the dialer and go to Battery history, under Sensor usage it says that the Android System has been using it 100% of the time the phone has been on for "Since last unplugged", "Total since boot", and "Total in all time". The thing is, I stopped using auto brightness a few days ago, so I don't know what the problem is. Is anyone else having this problem? Is this typical of the Atrix? My N1 never had this problem. Any suggestions please? Thanks.

I have the same battery drain issue while the phone is on stanby. I fully charge my battery to 100%, left the wifi on and went to sleep. Woke up and battery is 60%. Try again the next night. 100% battery, turn wifi off and when I woke up the battery was 96%. So from 10pm-5am i lost on 4%. So something is wrong with our wifi sensor.
Well leaving wifi on will drain the battery. My issue is the proximity sensor I believe. I factory reset my phone just now and I'm still plagued with the same issue. So I don't believe it's a rogue app. Can anyone look at their battery history and tell me their usage percentage? I'm afraid my problem is a hardware issue now.
Can anyone check out their battery info with *#*#INFO#*#* and tell me their Sensor Usage by Android System? I just need to confirm to see if this is a hardware issue for me. Thanks!
I'm not having any battery issues and my sensor usage is 100%.
I leave GPS on, I've been texting on and off, played about half an hour of angry birds, and spent maybe 30 minutes on a call. Started at 8am now it's 1:47pm and my battery is at 60%. I'm not using juice defender or any battery management software.
Hope this helps.

Mine shows the same thing. I don't think this is an error. The system needs to be aware. This sensor could be the unlock button. I have great stand by batt unless wifi is on which is normal

Ah I see, thanks for your input guys. It's just that I haven't had the greatest battery life, I can just see it drop with battery circle widget sometimes :/. Plus, coming from a N1, its sensor usage was low so I thought this was a problem. But this puts my worries to rest, thanks.
Seems every Atrix is a new world, just as my Milestone.
Do you guys have "Sensor Rotation" enabled in the Phone preferences? This was known to drain the battery of the Nexus S/Vibrant.
Hey,
I have just recently noticed a weird problem on my Arc..
When the battery goes below 20% it shuts down (similar to the way how it would shut down when the battery is out).
Then I need to connect the charger and switch it on, after which the battery will show at 1% and in 5 mins it will change to 21-22%...
so basically below 20% the phone thinks its actually ran out of battery even though it hasnt and hence shuts down..
any ideas about what could be causing this? is it a problem with my phone or the battery?
thanks

First thing you need to have "root". If you don't haven't rooted, use GingerBreak to root. Search the forum for the thread.
Second install Battery Monitor Widget from Market. Open the application (This is a widget. So you may want to insert the widget in your home screen), press menu and click "Statistics" option and it will prompt you for confirmation. Once done reboot to make sure it's cleared properly (Not necessary, but recommended).
Hope this resolves your issue.

I had a similar problem with my arc after charging it for the first time (charged it till 100% with the phone turned on). Then, after I used the phone, when it reached 10%, it just shut down. Then I decided to charge it with the phone turned off and this really helped. After two full charging cycles, the battery is acting normal. Now my arc shuts down at 2% which I think is normal.
Clearing battery stats has worked so far...thanks a lot...

Great to know that. Thanks for the feedback.
Anyone else having this problem? All the sudden Android OS is taking a ton of battery, killed half my battery overnight while the screen was off. Anyone have any of these problems?
Android OS is too general to say what is causing the wakelock. Use an app that can see which process is causing the wakelock directly and you will know what the problem is.

Then you definitley have an app or two that is causing it. Try CPU Spy (let's you know if you get deep sleep or not) and see if that helps any. I hate battery drain so best of luck in solving your battery drain issue.
Since I've upgraded to 4.2 roms on all my devices I've noticed this too. Normally, Maps is the culprit causing a "normal" wakelock. Google +, Latitude, Google Now, etc. This is just the way Google operates now & the biggest difference between 4.1 & 4.2. I've taken to disabling Location unless I'm needing GPS service. It checks your location every couple minutes it seems.
I've had a situation you describe a few times caused by media storage. It keeps scanning the SD card. Sometimes a reboot helps but mostly I've just changed roms instead of chasing it. Better Batt Stats should show it somewhere. Keep looking, look in "alarms". Also you might try GSam Battery Monitor. That app has come a long way lately & also helps finding battery sucking sources.

For me it was Viber. After deleting it I get almost no battery drain over night. Maybe 1% in 8 hours...
Hey guys, so I'm not sure what's going on but myself and several people on reddit are experiencing this issue:
http://www.reddit.com/r/nexus4/comments/1j7o85/n4_shuts_off_overnight_after_43_update/
Every morning since I've gotten 4.3 update, my nexus 4 shuts itself off throughout the night. It does not boot up until I force a shutdown (volume up and power) AND THEN try to power it on.
My nexus is completely stock, it has not been rooted or even bootloader unlocked. It seems to work fine regardless, but I like to keep my phone on in case of an emergency.
Can someone shed some light on this?

This sounds like the sleep of death issue. User tkolev has written the Safe Charge app to prevent this from happening when the Nexus 4 is charging. You can read his discussion of the issue at http://forum.xda-developers.com/showthread.php?t=2226698. The app is available at https://play.google.com/store/apps/details?id=com.sash.sodeliminator.

Thanks for the info Bob. However, I don't charge my phone throughout the night, so I don't think it's that.
It's not the battery either because when I do power it up, it's usually at least 40%+ battery. I'm really at a loss as to what could be causing this.

Sleep of death happens when the Nexus 4 is in deep sleep mode and fails to respond to a key press and can occur whether or not the phone is charging at the time. If you are able to charge the phone overnight, I would install and enable Safe Charge to see if it keeps the problem from occurring at night.

That's terrible . It only started when I updated to 4.3, and unfortunately I can't charge overnight. I'm guessing the Safe Charge app drains battery? If so, I don't think that would work.
Is there seriously no other way to solve this issue than a wakelock work around? It seems pretty significant to simply ignore on Google's part.
i hate to say it, but you may have to do a factory reset to determine whether or not its the phone, or some app that you have installed that is not playing nice with the update.
I've found the issue, turns out Netflix's chromecast update screwed up with 4.3:
http://www.reddit.com/r/Android/comments/1jdenw/psa_if_you_have_netflix_read_this_before_updating/
Fix: Uninstall Netflix or stay on 4.2.2 until resolved. Thanks guys.
It keeps shutting off at 3:07 every night?

i have update my SM-N9005 from 4.3 to 4.4.2 through Odin. rooted. with CWM Recovery.
tried probably 3 custom ROM that support 4.4.2 and end up on the Official leaked.Build 4.4.2 ( rooted)
the battery performance is driving me crazy.
on 4.3 stand By mode i used to loose 0.8 per hour now with the same setting same features turned on. i loose 2.3 percent per hour.
on 4.3 screen time with the lowest Brightness i lost 1 percent every 10 minutes. now i loose 3% with same brightness level. 3 percent every 10 minutes.
Android OS and Android System are always on top of screen in the battery Graph. i
media is also on top of the screen in the battery graph.
have tried a lot of solutions and factory reset with no luck at all. ( i have placed the device with Airplane mode with no SUCCESS )
installed a lot of battery analyzer apps did not have a clue who's eating all the Juice.....
any idea how to fix this??

Partial Wakelocks are usually caused by apps running in the foreground. There's usually not much you can do about that. If you are actually using the phone, battery will run out. What you need to find out is what happens when you are not using the phone.
Do this:
1) Charge the phone to 100%. Disconnect the cable.
2) Let the phone sit idle for 1-2 hours with screen off.
3) Get Kernel Wakelocks from Better Battery Stats.
Then you'll know what's eating your battery when you are not actually using the phone.
In my case, I get ril-fd, l2-hsic and wlan_rx_wake wakelocks the most. I know the causes, but I can't do anything about them without rooting.

I've noticed the first 10 percent (from 100 to 90) go away fast as hell. Use your phone as you would today, just make sure you have enough juice by the end of the day. Leave it as it is overnight and then post your screenshots.. You don't seem to have any wakelocks so your battery shouldn't be draining.. Mine is going like 1% for 8 hours or something, the problem starts when I turn me screen on lol!
I had this problem on my all my Samsung device
the only solution was to take out the battery for a few seconds

i am loosing more than1.5% per hour where on stand by mode... everything is switched of.f im surprised there is no wakelocks showing... ill wait till the end of the day.
its been 4 hour since last charge and now im on 93%..
im assuming the drain is happening due to the bad reception where i am at.
how do you manage 1% per 8 hours that's Awesome (knock on wood) :laugh: .. is this with WIFI and Data on?
i don't understand ... how come i have no wakelock after screen off.. and my battery draining 1.5 % per hour on stand by mode.... and android Os always on top ?
BBM.
And I haven't done anything special, actually you have to do something to NOT get great battery life while idle. After a factory reset, nothing disabled (so G+, G search and all those wake cycles still present) with WiFi off and Mobile Data ON I lost the usual 1 to 2% per 8 hour sleep. The problem starts for me when I turn on my screen, not when it's turned off

It's caused by broadcast packets sent by other devices in your network waking the phone up. The solution is to install a custom kernel that filters such packets.
