[Q] Suddenly Nexus battery drains quickly

Hello all.
I bought a Nexus One in at the beginning of the year. It's not rooted and I've had no problems from it till this month. I can not say the timing is exactly this, but it seems the battery issues started just after the FRG83D upgrade. I am accustomed to using my phone for most of the day before it needs to be charged. 12 hours or more with moderate use. Since around the FRG83D update my battery is about dead in around 4 or 5 hours. I haven't changed any settings or gotten any new apps or anything for quite some time.
For example, Friday night I charged my phone to 100% and then unplugged it (to plug in my girlfriends phone) and went to bed (about midnight). At 5:15am my alarm went off, i glanced at my phone and found the batter was at 10%!! the phone had been sitting there doing nothing all night with the screen off. I checked the battery use screen and it showed cell standby and AKMD taking up all the battery (55% and 35% respectively). I should mention that I have full signal where I am and have never had an issue. I cut off the screen rotate in the settings just in case that was part of it (AKMD being the gsensor i believe).
At next full charge that day i noticed the same problem, after being at 100% my battery was down to 10% after about 5 hours, almost the entire time I didn't use the phone. This time "display" was the largest percent by far (followed by cell standby), but clicking it showed only 15 minutes of use time for the display as I had purposefully not messed with the phone much.
Last night I had to be out and a bout so I decided to test things again. Charged full and cut airplane mode on. about 4 hours later my phone was down to 20ish percent, the only use of the phone being me looking at the charge level a couple times through the night.
I installed "spare parts" app and it shows my battery as being in good health and such but who knows how reliable that is.
Anyone else having similar issues? Any suggested remediation measures? I'm considering flashing the phone and reinstalling apps and such but would rather avoid that having never done that before and not having a desire to deal with setting everything back the way I have it.
Don't know if it matters but I run LauncherPRO and I do use the friends widget but it's never seemed to really cause battery issues before. I also run the news/weather widget, but again, no previous problems.
Any help would be great
Thanks!

In the spare parts app check partial wake usage. See if any apps are not letting your phone sleep.

nothing stands out other than UID 10073 which is handcent. currently my phone is charging but I'll pop it off the charger soon and watch the battery drop time again. I should note that inbetween all the tests so far i've rebooted the device so hanging apps of any kind should be killed off...

What ROM are you using?

Are you using Extended Controls? There is an issue with that and FRG83D. Uninstall it until the dev sorts it out.

yeah i am using extended controls. i'll take it off and see what happens.

Me too
I Have exactly the same issue, also have extended controls. Uninstalled and waiting to see if that works.
Cheers for the suggestion.

That did the trick! Loss like extended controls was the problem. A shame as i really like that app. Will hope they update and fix soon. Thanks!

Extended controls updated!

Yup, uninstalling fixed it for me too. Haven't seen the update though. I remember seeing an update yesterday, but I had this issue with that update so that did not fix it for me. Hope they update it again soon

I think it was updated again today. Now v5.03, and it seems to work properly.

So nobody saw Extended Controls showing up in Spare Parts, System Panel or other such programs?

My phone turns off at 5%

My phone turns off at 5% every time!! The phone is working great. It doesn't turn off randomly but everyday at 5% it turns off and tells me to plug in the charger. After plugging in the charger the phone keeps on showing the battery logo and it turns on after pressing power button a couple of times while the charger is plugged in. What could be the problem? Or is it normal? I remember when i was on stock, the phone used to turn off at 2%. Im using Chroma Rom.

Seems normal to me. The battery condition becomes slowly worse.
When possible don't discharge below 20-30%.

haven't seen one of these in a while. people used to talk about battery calibration, but i'm not sure if it is a real thing.
check out this thread: http://forum.xda-developers.com/nexus-6/help/dying-17-battery-t3062050

The battery on this phone is being let to go very low in the normal 100 - 0 range as it is. As it ages the low end will drop quicker and quicker. The qhd oled they used on this phone is really not nice for the battery. You can buy a new one on aliexpress.

Fixed!

Nice to hear. Success with Android N.
I wait for the final version; because mob30o is working fine.

Can someone make Kernel/Mod with disabled overheat protection? Will donate.

Hello,
recently I bought LG G Watch R and after updating to Marshmallow the watch started turning off randomly, and was unable to boot to the system without being on the cradle. I've read a lot about it on the internet and tried all sorts of solutions, but without success. Then I found that my temperature sensor is giving wrong data. My watch is idling at 50 - 55C and when put on cradle temperature immediately drops to 40 - 45C (overheat protection turns it off at 60C). So is there a way to turn off overheat protection or change the temerature the sensor is reporting with Kernel/Mod? I'll be glad to donate if someone is to make such thing.
Also excuse my mistakes, I'm not an English speaker.
Cheers.

Have you ever found out a solution? I think the most common thing to do is to buy a new battery, but I ordered one from China so it's going to take a while until it arrives and I'm hoping to try to improve the condition of my current battery a little.

Unfortunately, I haven't found a solution yet. I was about to do the same thing as you, and buy a new battery, but then I read a post on reddit about a guy with exactly the same problem as me, who bought a new battery and the result were disappointing.
Do you have exactly the same issue as me? Because I've read about people's watches shutting off but not because of wrong readings of the temp sensor, but rather battery issues.
When you receive the new battery be sure to update me on the situation.
Thanks!

To be honest I didn't check the battery temperatures. Did you use an app to do so, or adb? I will check and let you know... it might indeed be more battery related than temperature.

I had exactly the same issue.
When my g watch r was charging on the cradle it worked flawlessly. When I removed it from charging it turned off randomly, sometimes it managed to boot and stay on even for hours, but most of the time it turned off instantly.
I thought the problem was either on the battery or on the power regulation ic, I didn't think about temperatures.
So last week I've bought a new battery, replaced it, and tada! The problem was the battery indeed!
The smartwatch is running perfectly now, apart from the bugs and the errors of aw2.0

For temp check I'm using app called System Info For Android Wear. You can check your temps to be shure.

I'll try Wear 2.0 and if the problem persist (most definetely will) I'm going to try with new battery. The problem with new battery however, is availability and ridiculously high shiping taxes here in Europe.

I know this is old now but has anyone solved this issue?
I've replaced my battery yesterday but the problem persists. The temperature floats around 50C and it rises to 60 quickly and shuts off if i do anything. Please share if you have a solution. Thank you.

I'm facing the same issue, battery has been changed but still getting hot and shutting down... If anybody knows a solution !

I have the same issue. I replaced the battery, even downgraded from 2.0, but the watch still frequently shuts off. I was able to get it to work for a good while by putting it in the freezer for a few minutes before powering it on.
Edit: its as if the cpu temp sensor has lost calibration, but since the freezer trick works, what about a mod that would move the shutoff threshold a few tens of degrees up?

same for me, it works after having spent few minutes in the freezer and then shuts off

The same thing happened to me, I changed the battery and the problem is still happening.
something new?

This just started happening on my G Watch R as well. Sometimes the heat generated from my wrist is enough to cause the watch to shutdown or reboot from overheating. If it isn't a failing battery, as some of you have noted through a battery replacement, then what could it be?

I had exactly the same symptoms.. but not any more.. after I changed the battery1.5 months ago.. No power off since then...
no idea what else could it be.. maybe some app actuality coursing overheating.. ?? But mine sometimes just died in between of factory reset.. so in cant be custom app..

camera causing p9 to shutdown

hi hope someone can help with this.
I have a huawei p9 32gb EU version
model EVA-L09 emui 4.1.1 (still on) android 6.0 (says no update available)
build number is: EVA-L09C432B182
An issue seems to have developed in the past 2 weeks (i've had it almost a year) - it has decided to close itself down when I try to use the camera. I am using the default/stock camera app not a 3rd party one. I want to make clear it does not happen every time seems (at the moment) quite random/intermittent
The battery was at 79% the first time it happened and a few days ago it was at 55% and it happened. Auto flash was on but flash not activated at the time the phone shut down.
The first time I thought I just hadn't realised the battery was that low but when I plugged it in to charge it said 79% on screen.
A few days ago when it was 55% I was able to put the phone back on after it shut itself down and it was fine/behaved normally since putting it back on - the battery appeared to drain at the usual rate. I even took a few other photos after switching it back on & it didnt shut down. I had been using camera the same morning when the battery % would have been higher & it didn't shutdown then. (& i actually took quite a few photos during that time).
Hope someone out there has an idea of how to fix this issue, though i'm thinking its maybe the a sign the battery may be failing?

I also have this issue, I think it may be a sign the battery is beginning to fail, or possibly the cpu gets too hot. (again first started happening around a year into ownership)
Under 70% battery if i take a bunch of photos it can shut down but would normally turn back on again with 20% less battery. if battery gets less than 50% then if it powers off, it may power back on breifly and then go back to the exclamation mark for empty battery and shut down.
I have tried following the guide to calibrate the battery (let it charge to 100%, turn off, plug back into charger) but it made no difference.
What did help a bit though was ensuring cloud photo apps (google photos/onedrive etc) were set to only upload photos while on wifi and charging.

Hi, I have the same issue with my EVA-L09 with EMUI 4.1.1 build EVA-L09C900B182 bought in october 2016. Shuts down after shooting few photos/videos and can't start it again without plugging it. Once plugged, the battery level seems to be the same as before the shutdown. Seems to happen with any battery level.
If anybody can help solve this, that would be great. I can't decide to change the battery for the moment without certainty that it would fix this issue.

To all of you...unlock bootloader and update firmware. Maybe your issues will be solved. Its a conflict and not a battery issue
Sent from my EVA-L09 using XDA Labs

Any resolution?
I am having the same problem with my L09 and the P9 camera app. Was on Nougat so rolled back to MM in attempt to fix. Also tried a faster SD. No luck with either.
No such issues with other camera apps from Play Store, but they don't use both sensors.
Anybody resolved this problem definitely yet? If yes, how?
Thanks.

I have the same problem since the last 6-9 months.
However I noticed that the problem occurs when I make photos when I'm outside and the weather is windy/damp. I never had the problem when shooting photos inside, always outdoors.
The solution is indeed connecting the phone with a charger (or portable battery) or wait for a couple of hours.
It could be a problem with the battery but it is strange that the phone is ok again after charging a couple of minutes. If it was moisture this idid not yet vanish in just a couple of minutes. Maybe a sensor which is not working ok (or the firmware is not resetting/reading it correctly) ?
I'm thinking of sending my phone into repair for this problem, however I think this is a difficult to identify problem because it does happen randomly (as it seems).

I'm having the same problem, after battery goes under 50% It drains fast, bellow this it only takes 30min of use to shoot down, taking a few photos just makes it drain even faster. And when plugged to the charger it suddenly gets up to 40% . I tried everything software wise with no luck. I bought a new OEM battery planning to change it this week, then I'll post the results.

I am facing the same problem L09C432B395. I observed its somehow being related to cold temperatures outside in my case - it happens only when walking outdoor and the phone is in my hand for a while - so its probably cools down. And than when pressing the camera button I see the message "waiting to sharpen the photo" and then beeeep! battery down to 1% and phone shutdowns. Regardles the battery level.. happening accidentaly and randomly, but only once a week.. and only when taking phone outdoor in a winter time. I did factory reset, re-installed the latest ROM etc but the problem persists. Might be some conflict between battery state and temperature read error?

Update: I change the battery, everything back to normal. I used a OEM battery, screen time is +6h with moderate use during the first row cycles of battery use from 100% to 10%.

Hi all together. Faced the same issue up times (Huawei P9 EVA-L09C432B395, Kamera App 4.1.1) with battery in good state 46 to 76% and taking a picture caused draining it to zero at a moment. Sitting down immediately. BUT only if flash ? is set to bulb-light ?! Tested it several times. Normal (auto/always active) flash is ok - but not bulb-mode...
So, that's obviously the reason - but where's a solution? ?
Some Huawei officials here at xda? ?

Same problem here and without solution yet ... camera causes phone to shutdown and battery indication goes crazy.

Experiencing the same issue on both P9 we have and getting very annoying would be glad to see if is there any solution of this.

These are my exact symptoms - combination of cold and camera gives false battery reading and shuts down phone entirely. Software update hasn't fixed.

I have same problem
EVA-L09C55B383
it's the last firmware
emui 5.0.1
android 7
at 50% battery i make a photo with flash and the p9 turn off.
to turn on i need connect it to recharger.
it's very very impossible.
i think to send it to customer care.
have someone resolved this issue?
i ask to huawei on facebook. i wait a answer.

Any luck with Huawei support for any of you?
Hi,
I'm having the same problem. It's amazing how there's no information at all from Huawei about this issue... it's frustrating. I was planning on buying a P20 during this year and give my P9 to my wife, but if she can't use the camera it's useless. And I will not buy another Huawei if they don't do anything regarding a problem like this one...
Did any of you had any positive experience with Huawei Customer Care?
Thank you!

Even when connected to charger!!
Even when the phone is connected by USB to my computer and charging, if I open the camera the battery % starts to drop like 1% every 4-5 seconds!!
So the battery is being drained faster than what it charges.
I close the camera and it starts charging again.
Huawei, I was very happy with this phone, now I'm constantly in fear of getting out of battery in the middle of an unknown city while taking photos!

Verizon Note 9 OTA N960USQU2CSGA Night Mode included

Verizon just pushed the July 1 security patch to my Note 9. It's a feature update along with bootloader V2, QR Scanner (included in the pull down) and night mode is included in the camera. The build is N960USQU2CSGA. Some screens have been included.

I just got the update as well. Honestly the bootloader part is disappointing. But I'm not bothered by it. I do think the phone is running smoother. But also it could be draining my battery worse already.

Haha yeah I rebooted the phone about 3 times after the update. Charged it full to 100 and it seems to be draining normally. The phone does operate smoothly it seems and I haven't had a chance to check out the night mode or QR scanner, but it's nice they were included. ?

I feel like my battery has been draining today too after the update. But it usually on a charger while at work. We will see tomorrow how it handles a whole day off the charger.

Guess AT&T still waiting

Have you noticed the selfie shape correction is greyed out and unable to be toggled off and on? I tried every camera mode both front and rear cameras and the option still never became available.

This thread would be better if someone would actually grab the OTA link instead of just talking about it.

For those that feel like their batteries are draining faster, check your battery stats and is Google eating up a lot of battery? Mine was yesterday so I cleared all it's stored data and cache, force stopped the Google App and then rebooted phone. Seems to be back to normal today... This was on my unlocked Note9.
Does anyone have the update zip file for this OTA?

the att is out too!
Thank you
