Hey Guys,
I have a nexus 6p the 64 gb version ,and its one of the greatest phones I have ever owned. Everything about it is great, unfortunately the past couple of weeks my phone battery started to drain extremely fast. My phone now doesn’t last a full day and it constantly overheats. I’m a very heavy user, I almost do anything electronically on my phone, but before the battery drain my phone didn’t overheat nor its battery drained that fast.
There is no apparent reason why this is happening, I did not change my frequency or intensity using my phone. But I think there is possible reasons:
-Google latest update
- Charging my phone BRIEFLY with a non-certified type C cable (I didn’t know there was an issue with those cable before)
- A certain application that runs in the background (phone is always warm and when on usually overheats even if just browsing)
One of the great things I admired about my Nexus was its long lasting battery life and rapid charging. I’m really disappointed, I really liked this phone and wanted to last. Please if anybody faced the same issue or have any suggestions, solutions etc, please share. I have attached a report showing my battery use.
Thanks Aalot
**my phone is not rooted or anything it’s just plain stock android
The first thing I would have pointed out, is a custom kernel, tweaked inappropriately. But you ruled that out.
Now since your device is not rooted, there are not much ways to track the drain. I certainly believe that, there is a specific app that is causing the drain.
First of all, thanks for your response.
A small percentage of the battery is consumed by apps the rest is for the screen

Do you know any application that can measure each app battery consumption. Because it will be very difficult determining which app is sucking all the juice

GSAM would, but I heard it is a battery drainer itself on the 6P.

The drain was there before Gsam actually I used it to investigate the cause of battery loss and forget about how it can measure app consumption

I just got mine last Thursday and I'm also a little disappointed with the battery life. When I set up the phone, there were 3 or 4 google updates and the phone only lasted for less than 8 hours. I'm thinking it's due to the whole set up process.
I did a hard reset due to missing wifi passwords and I'm currently monitoring the battery drain.
Coming from OnePlus One, the battery life on this is really disappointing. But then again, I always have my anker battery charger with me. I'm hoping once the apps settle, battery life should improve.

I uninstalled FB, Messenger, and a couple of other apps that were restored from initial set up, powered off and wiped cache. So far, battery is holding up. If drain continues, I will factory reset and install apps one by one

I am having some success with wifi off during sleep and turning off bluetooth.

Facebook messenger used to drain my last phone battery (HTC One M8) at an alarming rate. I've just used the Web browser since.

Hey guys, I removed alot of applications, and btw I never installed Facebook messenger on my phone. But the battery is still draining.
The phone is constantly warm, and sometimes hot, even if its on standby.
Any suggestions?
Its very strange that the majority is not facing this issue (it's a good thing),

This is happen to me too. No new app. It is appear that if I reboot the phone after disconnect from from the charger then it is doze normally otherwise android system will keep the phone awake. Bluetooth does not seem to matter on or off. This is happen after april ota.

Go to Settings >Battery and see what is causing it. It may be an app that you updated. Try wiping cache or uninstall/install the updated app. If still draining, you may have to factory reset from boot and install apps one at a time instead of restoring backup.

Same here. Tired of this sutuation already, sometimes it works properly 1-2 % even 0 on morning, but sometimes it loses 10-15 %, I didn't install any new applications in monthes, it just started.

It seems that the battery drain on my newest N7 (RMA'd first one) is waay worse than on the other, I'll attach some screen shots of what I mean.. it may be just the WiFi is using a lot more than the other's :S I left it 4 hours alone with WiFi and the battery drained 20+ % which even with WiFi on seems excessive does it not? Is it possible I got one with a faulty WiFi radio? I will be testing tomorrow (or maybe tonight) to see battery drain with WiFi turned off to compare, because it also seemed to drain fast when I was just out and about with WiFi off :/ worried I have bad battery, deep sleep isn't working right (it is going into deep sleep or at least thinks it is from looking at cpuspy), or faulty WiFi... or just too early to judge XD has anyone noticed battery improve over time ? I forget if I did was a month ago I got the original
BTW first screen shot was taken pretty much right as I was leaving for work, so you can compare the battery drain there..

I doubt it's a bad wifi radio, its probably an app that is syncing like crazy in the background.
I'm currently watching the MediaServer app use a disproportionate amount of battery (14% and rising). I deleted a number of images which must of kicked in the scanner which must be very inefficient.
I also noticed my N7 become very slow at the same time.
Possibly you downloaded a large amount of images/music/etc before putting your device to sleep...

I really wish I could figure out why maps keeps starting a process.. can you check to see how many instances of maps there are ? In particular one running Prefetcherservice.. as for the other comment, media server is sitting at 6%, android is at 14%, and screen at 67%.. though I did copy a bunch of songs and pictures over after the RMA, is there a way to fix these or should I delete them to see if it gets better ?

Bahaha good one I dunno, the problem is that this is literally my fourth N7 since the other three allll suffered from major screen lifting, so maybe I am looking for something wrong just so i can make sure it's perfect... Though I do think the battery life is pretty weak, I think I may have figured SOMETHING out, the only difference between this and my original is that my original had a huge section of the map of my area downloaded, and since I did that maps hasn't started any additional processes.. so good sign ? maybe ? haha

Yeah this might be a good time to stop looking for trouble and just enjoy the tablet for a while. I drop mine on the charger in the morning and don't ever really think about the battery other than that. Whatever the battery stats say now they won't say in a week and they won't say after you flash to a different ROM. If you have wifi on apps will sync and the tablet will loose it's charge. I'm never far enough away from an outlet to make it much of a concern. So maybe just take a breather, install the Angry Birds and have some fun for a bit. Eventually we'll have ROM's and kernels that make this thing sip electricity but for now I get the few hours a day I need out of it on one charge so I'm set.

You think the battery life will get much better than what it is? My only other android experience is my HTC Desire Z which has a horrible battery as it is so it didn't improve much at all with custom roms
Speaking of improved life through ROMs and kernels, have you noticed any kernel providing particularly better battery life ? I'm on trinity right now, no voltage changing, but underclocked to 1.1 ghz from 1.3
Factory reset, see if the problem continues. That's the only way decide if it's a HW problem.
And my N7 uses effectively 0% battery in standby, it was off the charger yesterday for 6 hours and when I started playing around it was still at 99%. I turn off wifi on screen off, however.
Use http://forum.xda-developers.com/showthread.php?t=1179809 to find out what's waking up your phone, the apk is in the second post. Install, charge it up, unplug, leave for 4 hours idle then look at partial wakelocks and alarms.
I saved quite a bit of standby time by disabling location services and Facebook.
If your not using nfc that could save battery?

So it seems like partial wakelock is mostly audioout_2 which i assume comes from me playing a game with music amongst other things?
Alarms says com.google.android.googlequicksearchbox has 50 wakeups, and maps has 38 :S why does maps keep trying to kill me?! and what is the googlequicksearchbox doing waking the tablet up...
Wlan_Rx_wake seems to be the culprit of semi bad battery. Is there a way to prevent the tablet from waking up all the time? Maybe just unsync or turn off WiFi instead?

When my battery drain was bad I had something like 250+ wakeups from maps under the alarms section in only a few hours off the charger and Maps was showing up as the most common reason for partial wakelocks.
I think AudioOut_2 is normal - Im not sure what it does though. Im now at 8+ hours of standby with 99% battery. Under alarms im showing 138 Maps wakeups and 76 from google quick search box. My drain is all gone now though so i assume this is within normal range. The better battery stats thread and a few other threads on XDA have detailed descriptions of the different battery draining wakelocks and possible remedies. Not all wakelocks are bad though.
I have had this phone for about 2 months now and everything has been exceptional with the phone. Have seen people complain about the battery life, however it has been really good as far as my experience is concerned. However since a week I have seen the battery screwing up a lot... A LOT.
I always used to charge my phone daily in night. Plug it in..set an alarm of 3.5 hours (yes it takes 3.5 hours to fully charge from less than 10% stage) wake up..turn charging off..sleep back. Okay, some of u might think it is stupid but can’t risk of leaving it on charge the whole night and burn my phone. Anyhow, so, since a week what I do is I charge my phone whenever I want (read it on a few thread and articles)..be it 50%... 80% or even 92%. I just make sure its 100% whenever I leave home.
But something weird has started happening... The battery percentage keeps on changing.. For instance:
when I unplug it..its 100%.. within minutes of usage it drops to 99..then 98.. then 97 and suddenly it rises back to 100%. (Pics attached)
Sometimes when its on charge and I come to check SMSz and reply them.. battery % suddenly drops.. e.g: if its at 99%... it will suddenly change to 96% in a second and in a minute goes back to 99% .. so on and so forth. And sometimes even when its charging..if it is at 80%, it will suddenly shoot up to 100%. The percentage doesn’t change even after a reboot. Weird, isn’t it?
Now the most weird issue, since yesterday the battery life and dropped to 50% less. I used to get 4 hours OST and now I hardly get 2 hours. During night, the battery used to drop 2% in about 6 to 7 hours and yesterday it dropped 15%. There was this one time when it dropped 9% in 6.5 hours (pics attached). Tried seeing through Wale Lock Detector but there were no Awakes during deep sleep. Too weird :s
I don’t really know where did I phuck up as I haven’t installed any shaddy apps or something. Please advice.
My phone info:
All stock. No root (and not looking). No custom Roms whatsoever.
TL;DR... Battery acts weirdly. Shows inconsistent percentages. Suddenly shoots up. Suddenly Drops. And now the On Screen Time has reduced 50%.
It sounds like it's nothing more than a bug.

this has really kept me worried since a few days.
This is "normal" for the N4, and the most/all of them do it. Unreliable drivers, or a hardware fault, not sure.
Here are other threads about the various battery bugs, but there are many more:

Anyhow, this normal behavior has reduced my battery life a lot.. which I am not liking .. What to do?

Both my N4's (different H/W revisions) have been doing the 100 to 98 to 100 thing as well since new. Battery life is still excellent for me. An RMA would probably do the same.
Happens with my nexus 4 too. But this hasn't reduced my battery life at all...

You're pretty much stuck with that phone as you only have 15 days to RMA a device, your only option would be to send it into LG for a repair. My battery has acted up like this once so I stopped using the stock charger and it hasn't happened since.

Rebooting might help. Could also be an app that updated that now doesn't play nice. You could try a factory reset just to clear out some crap but I'd back everything up just in case first. Not sure if a factory reset deletes all your user data in memory or not. I only did it once right after I got the phone so can't remember. Hate to lose all your pictures, files, etc. that aren't backed up.

This is a question I can't answer along with any facts. I tried disabling it for 2 days and I noticed the OST reduced from 4 hours to 3.xx hours. May its placebo or something but then I enabled it...thinking if it's not doing any good then it's not doing any harm either.

Hmmm, I didn't know that. But why is that? Any apps or something to show the exact battery percentage left?
Happens to me once in awhile. Do a quick reboot, and if that fixes it, I would not worry too much.
Hmmm..
Yesterday when I woke up in morning.. the battery lost 2% only in 6 hours. I felt SOOOO relieved that my "good battery" is back. But who knew what was to come... today I woke up after 7 hours and the battery lost 15% .
My usage is always the same. I force close all the apps I use daily and turn wifi etc all off. So i doubt if its any app.
I updated to 4.4.2 a few days ago and am noticing faster battery drain. Just curious if anyone else noticed this?
Yup. Have tried factory resetting twice. Clearing cache. Disabling nearly everything possible. No avail.
Mine was draining a bit faster than normal after the update. I let it run all the way down, and charged it up, and it has been fine since then.
Hope it works out for you guys.

Here's one link of many I've found regarding this issue...Samsung has acknowledged an issue and is working on a fix:

I posted this in the 4.4.2 issues thread, but will post here:
EAS continuously running....I found this out as well after the update. I cant believe its low priority for such a major issue. I switched mine to manual just to be safe. I also found a major battery drain issue when surfing on the internet via LTE service.
Any way, I wanted to see if others could replicate my issue:
-Stock (non-rooted) S4 phone with the recent 4.4.2 update on LTE with 5 bars of service.
-I am using Chrome to surf the internet.
-I have Exchange and Gmail accounts. Gmail is set to PUSH and exchange is set to manual. (My hope is that having Exchange set to manual I avoid the EAS issue described above.)
-Majority of the boatware turned off
Scenario: While using Chrome to surf via LTE service I am literally able to see a 1% decrease in battery ever 2-3 minutes of surfing on the internet. Wifi is better, but still drains faster than 4.3.
Can anyone else try and replicate and respond back? I may have to do a hard reset to see if it will remedy the issue. :-/
Thanks,
Eric

Yes I have had worse battery drain with the KitKat update. Hoping for an AT&T update since we dont have the option to flash roms...
What are you actually seeing for battery consumption?
I have google+ at the top of the list with >30% use. Definitely new after 4.4.2 update.
Seemed to be ok for a day and then popped back up. I'm going to try to see if it's caused by 1st use of the camera.

I'm not using live wallpapers.
Rebooting the phone and avoiding use of the camera did not help.
I uninstalled all google+ updates that that has worked so far, but definitely not a long term solution.
Well I would up flashing the MK2 revert, then changed my mind and re-updated to NB1 (these two processes involved many full-wipes and even flashing a .pit file). Installed all my apps one-by-one. I'm now getting better battery life. Still higher than previous usage by Android System (usually ends up being 14-17%).
NB1 now works pretty damn well for me. Once we get root I will be able to disable some stupid things like the boot sound and charger connection sound, along with a few apps that just don't need to be running like Knox and Security Policy Updates...

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.
I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time
Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.
I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.
4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.
I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.
You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

I am overage to believe in this new-world mysteries... and I am still hoping that nobody believe in this stories. Please, let me not became an old, lonely infidel.
Nope
The update did not kill my battery. Did you come from a rom?

Agree and disagree!
I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

Everybody wants to be a comedian.
I don't have this issue but maybe affected people should read this : http://forum.xda-developers.com/showpost.php?p=52366635&postcount=236
I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.
Factory reset and see if it still happens. A dirty flash can do weird stuff...

Yeah, im not getting great battery life either since this update. I just reset the tablet in the hope of tracking down what's the issue.
Troubling, since battery life was so great previously.

With the joke being on the user that lost the function.
Let me know your thoughts
Unremarkable, nothing but security update AFAIK.

I didn't have optimizing apps like normal and the update was much faster, but than again that might have happened since we got Nougat and I didn't notice it in the last two updates.
Otherwise its typical security update.
Actually after I did the update, now every time my phone rings Spotify starts and I cannot figure out how to stop that from happening. Extremely annoying

S7 edge here. Got it last night, no issues so far. Wondering if anyone can report on root status?
EDIT: Actually working fine with no issues after several weeks.
Patch installed. No issues.

I had two bugs that it actually fixed:
When I was connected to AC power, and on bluetooth, and would hit the dialer app it would restart the System UI and display an error stating that the system integrity couldn't be verified and suggesting to recover the phone using the Verizon **** tools.
When you set a reminder and turn the screen off before the "Reminder saved" verbiage was stated then the phone will go ahead and say that EVERY time you unlock the phone.
It has caused noticeably higher battery drain on my S7E during the day. I left it fully charged and unplugged over night after the update, and it only lost 2%, so Doze is working in that case. But when carrying it around, it drains faster than I've ever seen it drain by quite a lot. I'm assuming it's a rouge app that has some issue with the update. MyRadar may be the culprit according the battery monitor, as it often was on my Nexus 6P.
I've cleared both cache's several times and done several reboots to no effect.
I was right, it was MyRadar. I tried to optimize it, but it did not help. I finally uninstalled it and my battery life is at least as good as ever, and it's always been outstanding on this phone.
As a very outdoor oriented person, so I love the MyRadar app. But it's been a glitchy app for me for far too long. I'm using Radar Express now instead, and it is not impacting my battery drain so far.
