Terrible idle battery drain! - Nexus 5 Q&A, Help & Troubleshooting

I have a terrible battery drain when my phone is idle. Tried everything, but nothing solved it. Ever since Lollipop I have this issue.
Clean flashed MM and still nop. Flashed ElementalX 6.04 yesterday which still couldn't solve it. This is frustrating :crying::crying:
I have disabled everything too. No Wifi, data, bluetooth, location...etc (My phone is not a smart phone anymore)
Only adaptive brightness is enabled.
Yesterday I fully charged and went to sleep to find out it has drained 28% after a 7 hours sleep. Removed all the unpopular apps (suspicious apps) as well. BetterBatteryStatus says my phone has been in DEEP SLEEP throughout the whole time too.
Please give me a solution

How old is your phone?? You might need to replace the battery. Especially you've already done everything from kernel, to clean flash to disabling apps and settings

your bstats also tells no abnormality? how about its partial wakelocks? can you post those so we can check it out?

According to BBS my phone has been in deep sleep throughout the whole time. I'm assuming its the battery, I need to replace it may be.
I charged my phone again. I will post partial wakelocks too in few hours time.
Thanks alot

Even though it may not make a huge difference but you can try draining the battery out to 0 (until the phone can't stay on even after a force power on) and a full charge (30 mins to an hour overcharging after you see full battery indicator).. Gluck.

I replaced my battery, I was getting hard reboots as well. But wow with a new battery and marshmallow my nexus is like a new device.

99% no or unknown signal.
That could be the cause of your drain, when the phone has no signal or poor signal it will use a lot of battery to keep the connection alive. Set aeroplane mode on

NFC services draining my battery

I just got the Sprint GS5 last week and have been slowly Turning OFF some of the bloat ware and downloading apps that I use. The past couple of days I have noticed that I charge my phone to %100 before I go to bed. I sleep for like 5 hours and when I wake up my phone has dropped to %89 battery. I went to settings>battery and have noticed that NFC services is causing the most batter drain....even though I have turned it off, forced stop and turned of S beam. I have also tried to turn it off and then reboot and charge phone, but I still see the NFC services draining my battery. Can someone please help?

I personally do not use NFC so I just froze the service in Titanium Backup.

I am not rooted and it won't let me turn nfc off. When I click on the tab in settings, it is gray and "on". It won't let me change it.

That is odd. You should be able to toggle it off in the settings.

Yeah, I know but when I go to that screen, it is grayed out and I can't toggle to off. It's also the cause of my battery drain. Any help would be much appreciated.

Have you tried turning off the phone and pulling the battery? If that doesn't work the only other thing I can think of is a factory reset.

Android System draining battery on lollipop, but only under wifi

the title says almost everything. I updated to last cmos12 release, flashed again, clean flashed again, wiped everything and fastboot super clean flashed again. nothing. Android system drains the battery on par with display. i have approx 3 hours cpu uptime for android system in a discharge cycle. but this behaviour simply disappears if i don't use wifi and only rely on mobile connectivity. ofc i have better battery stats and wakelock detector installed, so please ask me for things you need to help me understand and troubleshoot the issue and i'll provide them.
thanks in advance

I have the exact same problem, although I'm not working on a rooted phone. Working on LTE goes ok, but the moment I switch on wifi the phone gets very very hot and drains the battery. Other than 'Android system' I cannot see any other process draining.
no hot phone for me. i get lots of wakelocks but they're 1-2 sec each so nothing to worry about. the phone deepsleeps well too. but those 3 hours of cpu uptome for android system drive me crazy.
any suggestion out there ?
Most likely it is a bug from Cyanogen os 12.
As it is still an initial build, I think you will get a more stable build in near future.
I will suggest you to check the following option under wifi > advanced settings > keep wi-fi on during sleep option.
I have this set as always.
If you have the same then you can try with the other options.
tried but ofc i need data connection while sleeping and relying on mobile data is more power consuming so no, wifi has to be always active during sleep ^^

Try this, it worked for me. Wifi settings seemed to be the problem. Changed the frequency from 'automatic' to '2.4 Ghz only' in the advanced wifi setting.. Now all Normal. I almost returned the phone thinking of a hardware issue.

Galaxy S6 920I Battery Issues - Help and Thoughts

Hey guys, first of all let me make clear that I've been through every single topic available online on these battery issues, and I have tried everything but nothing works.
I love my S6 but its battery inconsistency is driving me crazy. I've got every single topic covered:
Location services and history off
Wifi sleeping on screen off
Uninstalled and disabled every single bloatware that Samsung offers
No facebook app
Screen brightness on 10% most of the time
Tried factory resetting and wiping system cache more than 3 times already
I was stock 5.0.2 and recently flashed stock 5.1.1 via Odin hoping it would solve my battery problems but it made my issues even worse. I get 2h SOT tops, and my device usually drains 40% of its battery when I'm in bed (11pm - 7am), even with Wifi/data off and all apps closed. Battery system monitor shows a 40% drop on battery caused by "Android System", and GSAM shows the same but with special drain for "Android System - celgeofenced".
I don't feel safe rooting right now and installing Wakelock because I've read a lot of issues related to Knox violation in the current rooting methods.
Any thoughts on that? I'm really getting to a desperate bottom line here.
Thanks.
I'm on a G920i Vivo - Brazil and I was gettin same battery drain as you. Unfortunately I only solved this issue making root with CF ROOT, TWRP, flash SUPERSU, flashed the DeepSleep zip via TWRP, wipe cache/dalvik and rebooted!
EDIT.: Deep sleep is gone after 2 hours, some app is using GPSD and killing my battery :////
Could you check if you have this option in 5.1.1 ???

Are you sure? The problem is 40% draining without even touching my phone. Does it seem fair based on your usage standards? Thanks

Help with Battery life

I recently got one of this phones off ebay deal. So far the phone has been really good (after going to 5.1.1) other than the battery life which is super terrible. I leave for office at 8AM and by the time I am back around 6:30 in evening its already down to 8-9% with barely 1 hour of SOT. While using the phone I can clearly see battery going down by 1 percent every two minutes.
One of the other things I noticed is it takes a while to charge battery. Almost takes 4 hours to charge it.
Have done everything listed in various thread on XDA to fix battery drain but nothing is helping. To summarize I have
- Rooted my phone
- Disable AT&T enhanced 4G LTE
- Tweak setting with kernel auditor
- Disable ATT bloatware
- Install greenify and amplify
- Installed CF.Lumen to control brightness
Not sure what I am missing here now. Any help is appreciated from you guys.
Does the phone feel warm on the back when it's just sitting?
If so, you probably have a runaway app. You can check the battery section in options and see what's eating battery.
I had this a while ago on nexus 5 with the ebay app, the same also happened to a friend of mine with the same app.
hello, there.
i had the same problem, it seems that your phone is not going to deep sleep mode.
i fixed my problem with Nitro X, you can find it here on xda.
now i am very happy with my battery, for example now it says on battery for 2 days 15h 29min 22s and still 60% battery remaining.
hope this helps.

Thanks. I am gonna give it a shot. I see they have 2 versions - X86 and Non-X86. which one should I flash? Also since flex 2 doesn't support any recovery (twrp etc) should I just flash it with Flashfire app?
hello kunalmalviya,
i downloaded the non x86 (=the arm version).
i do not know about flashfire, you should ask on the forum.
Please click the thanks! button if that helped.
PEACE.
Try reflashing latest software via LG Flash Tool.
I have no issue with battery life. It is slightly better than on LG G2 which is awesome. (3-4 hours SOT without any problems, no tweaks, no root, brigthness on 100%, Wi-Fi, NFC and LTE enabled all the time, Google Now enabled, Google Location Services enabled and lot of apps running in background).

Drastic effect on battery after downgrading to Lollipop

My LG G4 H818P came with Marshmallow 6.0 installed. It had bugs, unrootable and bad battery life. So, after a week or so, I used LGUP to flash a stock Lollipop kdz and then rooted it. Both of the procedures went just fine.
But the battery life has worsened drastically, let alone improve. For instance, I checked the battery at 92% before going to sleep and woke up in the morning with 71% but the whole time the screen was turned off and nothing was going on background. The battery doesn't even last 1.5 hours when I'm watching a movie or browsing the internet.

have you calibrated youre battery....???
charge your phone 100% and
calibrate it using battery calibration app from play store
it requied root
when youre phone is full charged 100% open this app and give it root acess and click calibrate
after that unplug ur charger and reboot your device
and discharge youre battery with normal use and after discharging to 10-5% charge it again... and its done
and if you want more battery juice
use these apps
amplify battery extender(requires root & xposed frame work)
powernap (req.. root & xposed)
if you dont have xposed
use l speed app download it from google play and toggle main tweaks (just need root)
see the magic when you left your phone at night for 100% at the morning it will be 98-99%
its awesome app just try it (it supports all devices)
Thanks a lot. I didn't try calibrating because I thought a decalibrated battery would show weird & incorrect percentage. Anyway I'll let u know after I do it
