I have everything running in the background disabled, yes the phone doesn't want to sleep.
Look at the Awake vs. Screen On graphs.
This would be a sign of a problem in KitKat, is this normal for Lollipop?
How do you even check for wakelocks without root?
Any ideas on how to fix this?
Please post your own graphs and stats.
Right now my idle battery drain is about 1% per hour. It used to be 0.3-0.5% per hour in Kitkat.
Maybe it's the Voice over LTE thing?
Have you tried a factory reset? I've read that some have issues on lp with battery life and a reset helped

I think the reset will reenable everything, not disable. No point in doing that.
What I'm trying to suggest is that although it will reenable any apps that you disabled, other members have had battery life issues, did a reset, and the battery life went back to normal.
You asked what you can try to fix it, I suggested. It's up to you if you want to try.

Yeah, thanks but using a hammer when a scalpel is needed is not my style of problem solving.
I'd rather find out what is responsible for the phone being awake than just try a "fix" by resetting my carefully configured and set up phone to Samsung's factory bloat, which is most likely not going to do anything anyway.
Alternative version of this post:
Phone isn't sleeping properly?
I checked the Advanced Calling, and it's not responsible.
See how the screen is off but the phone is still waking up very often? This was not normal in the older versions of Android, and would normally indicate a wakelock problem - where a piece of software is going rogue and keeps the phone awake against design.
This is how you can test this on your own phone:
1) Plug and charge the phone,
2) Unplug when fully charged, then don't turn on the screen for about an hour - the phone will record the wake up statistics, but will not blow it up so much on the horizontal axis that you cannot see the detail.
Does anyone know how to check wakelocks without a root?
Does anyone know what is responsible for these wakelocks and how to fix this?
I kept thinking it was advanced calling too. No clue why the radio is constantly on while on WiFi. I also hadn't better battery when I turned off mobile data. No clue what it is. I also did factory reset when I really didn't want too. Been few days and android system is still outta control.

Here is the link to someone that got it working on kit kat without root, may work with lollipop as well? http://forum.xda-developers.com/note-4/general/wakelock-detector-root-t2927706
I had / still having similar issues on my att note 4 after lollipop. One thing suggested to me that definitely helped (though my battery was still way better on kit Kat) was turning off device and removing battery for a few minutes. Then put battery back but don't turn device on yet. Charge back to 100 percent before turning on. This worked for me but like I said, it went from half the battery life as kit Kat to 2/3rd the life. Hope this helps. Also I'd like to hear what you find!

Ditto on the battery pull. If your only problem is battery then a battery pull and a cache wipe would be the less aggressive method. Otherwise a reset is in order.

If you use Power save location or full location (anything other then GPS only) it keeps WIFI on all the time. My guess is its any number of the google apps waking up and doing their location and other background things That's actually pretty good. My phone goes crazy during the day and I haven't rooted to determine what it's doing using BBS. from midnight to 7am, it's fairly idle, only losing about 5%. 7am-9pm, it goes crazy and doing all kinds of things; all google services and android OS related.
How does my battery life look? I still think it's WAAY worse on Lollipop than KitKat.
2 Hour Screen on Time (Doesn't seem like much)
I believe I put it in power savings mode when I went to bed. This graph is about 21 total hours on time. I've already done a battery pull and factory restart which definitely helped. Still don't think this is great battery life though..
Samsung/At&t started rolling out another update that I've heard seems to take care of the numerous battery drain issues. I haven't personally taken the update yet but I'm guessing Verizon will have this update soon as well...
I am having the same problem, only mine seems to be extreme. I got my Note back in November/December and I never felt I got the best capability out of the battery. Not terrible but not great that others had reported. After updating to LP i noticed a negative effect on the battery but starting yesterday it got really bad. I took screen shots before it died. My awake time is mostly constant even though I rarely used it throughout the day.
Something is keeping my phone awake and its gotten worse by the day

That's exactly the graph that I'm getting, 11 hours these days isn't terrible when I used to be able to get 27 hours if I really pushed. Looks like something is definitely keeping your phone awake. Your mobile signal isn't helping either. I am considering rolling back to Kitkat. Any thoughts on what might be keeping the phone awake?
I have noticed over the last couple hours that when I put my phone in airplane mode, that it behaves normally and the battery usage flattens out. Must be something going on with the radios? Not sure how to determine which one is the culprit though...
Or it could be something in the system that is running, but hibernates when it does not detect a connection. Diagnosing wakelock issues without root sucks.
After a reset, then a clean flash of LP 5.0.1, battery life is much better than KK 4.4.4
I'm also finding after a reboot and not touching my phone battery is pretty normal. After I start to use it the battery tanks and the highest use being android system, Android os, and cell standby followed by screen. May have to do some wiping and refreshing.

I've been troubleshooting this problem for weeks now - have never found a cause. I did a hard reset yesterday and have only installed the mainstream necessary apps - nothing sketchy or buggy at all.
My battery life is usually great and when unused drops less than 1% per hour...until suddenly it goes crazy and starts dropping ~10%/hour with NO USE.
I think perhaps something is wrong with my radio as the "mobile network signal" graph in the picture below is always spotty and shows the radio off for significant chunks of time when I know it's on. When these battery plunges start happening, it shows the radio as solid on, as you can see below...and reports the battery drain is from the radio.
A reboot fixes it but it comes back randomly within a day or two...the problem is that I can leave the phone unused for an hour to make dinner and when I pick it up next it has dropped a significant amount!
Hopefully AT&T will exchange it for me tomorrow and I will have better luck...I bought it on June 28th and tomorrow is July 28th...the 30th day, by my count.
Uploaded with ImageShack.us
16hrs on battery and still at 43% is pretty darn good if u ask me.
This has happened to me too on stock and AOKP. Just happened again a couple of hours ago.
So I did the exchange 4 days ago. Have not rebooted since then. Thought I was in the clear until this afternoon when the battery started to plummet again...I updated the screenshots in the first post with today's data. Very disappointed and not sure what to do now except to try and do a hardware reset and use the phone stock with no apps for a few days and see what happens...

I have used it extensively. Posted numerous logs and screenshots in the developer's thread and had them examine it...no one could figure anything out.
Tonight I have watched it plummet again. I turned off wifi - it kept dropping. I turned off mobile data, it kept falling just as fast. Lastly I turned on airplane mode and it seems to have leveled off...seems to me the phone radio is the culprit but I have no clue what it could be doing!
(Forgive me if I'm hijacking)
I scooped up my SG3 on Sunday, and noticed almost immediately that my battery drops pretty quickly. I haven't rooted yet, and needless to say haven't flashed anything on it. I'm completely bone stock. I guess I'm wondering the same thing, in that I may need to return to AT&T. I lost as much as 70% in almost 8 hours with moderate to heavy use (Web browsing, textibg, a few calls, etc).
Something else: there is an orange sticker on the box it came un, much like a price tag at a retail store. On the sticker it reads: "REMATE 7.11.12" and has me wondering if this is a refurb they unloaded on me. Any ideas about the battery or this stupid aticker?

I notice that my battery life seems very unstable - one day it goes 10 plus hours no problem, the next day with the same usage its dying at 8 hours. The phone went bezerk this weekend, to the point of multiple reboots and just turning the thing off since it was unuseable. Factory reset over the weekend, wow ! Battery life is rocking 12 hours easy with heavy use.
The software on this phone is strange to say the least -

The reason I say this, is because of the fact I've heard of 12 to 14 hours or more of battery with the same (mostly) moderate to (occasional) heavy use. I understand that usage = battery discharge, I'm not a fool.

my battery usually only lasts 12 hours with minimal use, the only way i can go more than 8 hours is if i switch on airplane mode while i know im not going to need my phone.. while at work.

So perhaps I'm worrying over nothing (hopefully). I have been doing full charge to full discharge cycles and charging once it shuts down to "gel" or "season" the battery. But, there still remains the question of what the "REMATE" sticker is all about. It clearly has a date printed on it, which strikes me as odd...

So check out this graph...update of the earlier one.
-turned off wifi - plummet continued.
-turned off mobile data - plummet continued.
-turned on airplane mode to turn off the radio - battery stabilized. You can see the plateau towards the end.
-turned off airplane mode - plummet resumed as you can see.
Any conclusions I can take from this? It seems like it's the phone radio/standby and not apps...

Of course but battery loss is a corollary response to usage. Who made the rules on what moderate or heavy usage is? Besides other factors like strength of signal, etc.
That said I personally average 10-12 hours with 4hrs of screen on time.

That doesn't explain why the actual battery it dropping so fast. I suppose it could skew the "reason" the system gives for the battery drop...but it's further proven by the fact that the only way to stop the drop is to turn off the radio - even turning off mobile data alone does not stop it at all.

Your sharp drop is correlated to heavy screen on time. Mine is correlated to nothing...just sitting there with the screen off and nothing happening that I can tell.
I reported this problem back in June. This same exact thing happens to mine. Normally the battery is awesome, but sometimes it starts discharging at a crazy rate at which point I restart thee phone to fix it.

That's definitely my problem. When gsiff_daemon hasn't gone crazy the battery life is very good. I've only had the phone 3 days now and on the second found the battery discharging quickly when the phone was in standby (like the OP). I diagnosed this to be caused by gsiff_daemon. Seems to happen after the phone stops responding to input then does a warm restart. I only found one thread on this issue on one of the other S3 forums at XDA (TMo or global?)
Is there any sign of a fix for this? This is making an otherwise excellent phone horrible. I tried to relate this problem to Samsung through their support site, but just got a generic robot answer. Samsung's support site appears to be useless. Is there any indication Samsung is even aware of these problems?
I use System Tuner to check for gsiff_daemon going nuts. I normally notice it because my phone gets hot. If you use the Task Mgr from System Tuner and turn on display of kernel processes, it will pop right to the top if that's your problem.
The easiest way to deal with the problem when you notice it is to kill the process with System Tuner. It will start up again, but will not longer pin your CPU. A restart also works, but takes longer (and uses more battery).
You might also want to set up the Watchdog app to notify you when gsiff_daemon goes nuts.
I noticed you posted BBS logs, but gsiff_daemon will show up in Process, which doesn't appear to be logged (at least it isn't in the log in just dumped from my BBS).

I noticed today that my phone connected to the computer's USB wasn't gaining any battery this morning. Unplugged I am losing about a percentage every few minutes, quite excessive. I recall that there was an update to AllShare today and looking into it "Media" is my top couplet in "Use details" using 55%+ battery. I am trying to track down the app or setting to fix this battery drain.
Going into Allshare Cast I can turn it off in settings, but when I go back in its right back on.
Under "Media" Included Packages are as follows:

Honestly, I have everything on except bluetooth and roaming. I even have a live wallpaper. Go to settings, then battery. See which process is draining the battery. This is my second Note. The first one stopped charging after a week. It would light up the red led and charging icon. Only give away was no charging indication on lock screen and no increase on charge level.

It seems that my device idle is never any where near the top. I just checked, its at 2% for idle. So something is keeping my phone on in the background.
Hi again,
Just about to give up on this tablet when I noticed that it seems to be the battery percentage setting that is causing my charging and discharging issues.
With the setting turned on and the percentage visible, the battery seems to discharge and charge oddly, and also the percentage shown does not reflect the amount shown on the battery icon, or at least it rarely does, but it varies.
With the percentage setting off, the discharge seems much slower and predictable.
If you have a p600, could you possibly try this for me with and without and see if it matches with my findings?
Thanks.
I'm having very odd battery issues myself. I'll give this a try and see if it improves for me.

Thanks for the reply. I'm not using any battery app, just the one that comes with the stock tablet.
I think I did encounter the same thing as you, and also unplugging at 100%, then taking it upstairs and looking and it was 96% or so, and then after a restart, it was 100% again. Very odd, but it doesn't do it for me unless the percentage setting is enabled.

No i suspect my device might have some deeper issue. I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

I can drain the battery from 100% to 0 in an hour of playing games but if i turn off the note and turn it back on, it'll be back at 60% or whatever it's actual battery level is. I can rinse and repeat and slowly get it down to 0. Either way the battery drains much quicker than it should. It could probably only last 6 hours of screen on time with very light usage. I might need to get motherboard or battery replaced.
I am still hoping that its a software glitch and something like this could fix it.

Yeah, mine wasn't that bad, although bad enough. Hopefully you can find a fix without having to send it back.

I wonder if the tablet needs a little time to calibrate the battery usage, maybe there is an internal process that has to happen over time?

I've had it since it was released in october or november and the battery life used to be good and last 10+ hours and probably 5-6 hours while playing games. Not sure what happened in between. It has taken a few very light drops with no visible damage and i did break (bend) a charge with it in the tablet but the charging port seems normal and still works fine.
Just checked with battery % off for 30 mins and battery dropped 4% which is normal.

I still had crazy battery drops with the percentage turned off. so didn't seem to make any difference for me.

Is your unit still rooted????? If so have you tried removing root and installing the most current factory rom.
Have you seen this post "Longer Battery Life (or How You're Being Robbed!)"
It may help some that are having issue with battery drainage but after seeing your post #36 in the BATTERY posting .... I'm leaning towards a cracked or damaged board from the few drops you talked about.

I've tried unrooting and odined back to a factory rom, also cleared my SD cards, nothing helped so i'm back to being rooted for now. I've done a lot of the tweaks to improve battery life but whenever I play games, it just drains like crazy even with minimum brightness. The drops were very very minor, like from 1 foot onto carpet and with a case so I doubt that it was the cause but I guess theres always a chance.
I'm still wondering if I should just live with terrible battery life and stay tethered to a charger or risk sending it back to samsung and having them find out it was rooted and overcharging me for repair. And I love the device so much, I don't know if I'd want to give it up for a week or two.

Tested again last night and this does seem to be the problem on my unit. Just over 2 hours and the battery icon had barely moved, and looking in the settings, it showed that I had 84% left. Hopefully it wasn't a one off.

Thanks :good:
So, I wonder which is correct, the icon or the percentage? If the percentage is right, my tablet is faulty. If the icon is right, it would seem to be ok.
And all these reviews and people that get 10-12 hours, I guess they went by the icon?

The percentage gives a more accurate time I guess.
But people and myself use the "Screen on time" as the usage data.

Was doing ok last night and then came here and the battery took a dive. Went and grabbed adblock for firefox and ghostery and ghostery was reporting 65 trackers on this site. Also the malware popups were becoming ridiculous and they only happened here. Going to do a factory reset and not come come here tonight, see if that helps anything.
I did do a bit of a search regarding the malware here, and it was being reported as early as last june it seems.
Hey there, new member although I've been reading these forums for months.
I've owned an iPad for a couple of years now. I use it from time to time which requires me to charge it about once every 2 months. A couple of months ago, I bought a SM-T800 and thought the battery life was horrible. Keeping it completely idle for 24 hours still drained the battery 11%! After a while, I left it dead next to the iPad.
Hoping Lollipop would help this issue, I took the opportunity to completely wipe the tablet and restart from scratch. Each day, I attempted improvements (using BetterBatteryStats) and took notes of those changes. The best I could get is losing 6%/day while the tablet is off (that is, screen is off, not powered off).
Yes, I'm rooted. Not much is installed. According to BBS, com.google.android.gms is the worst with 1639 wakeups, but disabling Google Play Services didn't help.
Is 6%/day when idle considered normal? It amazes me that the iPad is losing about 1%/day.

I've had on CM12 and it drained 0-1% while on idle. With touchwiz (lollipop or kk) I lost 6% on idle when I woke up from bed. So my result is that touchwiz usually has more drain than CM12. A few custom roms like Ironrom or Twdetox make it drain less from what I tested. But before you go through all that, I've seen a tweak to stop wake locks from Google services. I haven't test it throughly but seems promising.

I don't see what the problem of a small amount of battery being used if the device is on is?
It's obvious it's going to use some power, there are still things running in the background or you'd never get messages, emails, sync etc. Really the whole point of leaving it on.
Android itself is not the problem, it's more to do with Google services and apps.
If you don't want those things turn it off imo or completely remove gapps.

I use TWDetox v3.0 on my 8.4 tab s the SM-T800 version is beta at best experimental at worst at this time but I can give you my own experiences on a similar device, YMMV. On kitkat stock with my brightness turned almost all the way down and auto on, I also used greenify I would lose about 5-6% by the time I woke up. On this rom same basic settings wifi still on, greenify still on, tab set to low brightness I would lose about 1-2% over the same 8h though this os a debloated rom so a lot of samsung "highly important" apps are missing like milk and watch on and yea basically all the junk no one wants that runs at startup all the time.

I'm not saying it's a problem. The question simply comes from the fact that I'm comparing my SM-T800's 6%/day loss versus iPad3's 1%/day and wonder if it's normal or not. After all, the iPad is also syncing stuff and it's barely using any battery. If everyone tell me their SM-T800 drains 1%/day too, then I'll know there's something wrong on my side. If not, I'll live with the fact that the SM-T800 drains 6%/day.
I went on Cyanogenmod's site and apparently the SM-T800 is not officially supported. I'll need to read http://forum.xda-developers.com/gal...rom-cyanogenmod-cm-12-0-sm-t800-16gb-t3005540.
I think 6% a day is normal, the tablet is doing quite a bit even when sleeping, I have an SM-T800 10.5" with a the stock UK rom.
Is sleeping wifi scanning enabled, the T800 has that does it not.
John.
Hi to all. I recently bought an SM-T700 and still playing around with it.
I have disabled everything you could imagine when I turn off the screen:
Wifi Off
No Wifi Scanning
No Sync
No BlueTooth
Everything is off
Anyway, I'm also loosing around 6 to 8% in 24 hrs of idle / screen off.
I also have an old S2. If I put it in flight mode, it won't even lose even 1% during all night stand by.
Is there anything I'm missing here?
I don't see why it shall lose 6% if everything is off. It's just on doing nothing!
Thanks in advance and sorry for my english!

I was worried too and that's why I came here to ask if this situation is considered normal. It apparently is, unfortunately.
It seems the stock OS is taking more juice if we're comparing it with CM (according to DUHAsianSKILLZ) which only takes 1%/day. If it's true, I fail to understand why the stock OS takes at least 6 times more than that for the same results. That can't be good and we can't blame everything on bloatware.
This is a screenshot I a few months ago. This was when I went to bed and woke up in the morning. I forget what I did but, I did do something I don't remember that would stop wakelocks. I think I did a few things in app ops. This was touchwiz Lollipop.

Thanks for your replies.
I bought this just two weeks ago and was amazed about how low was the standby battery consumption after upgrading to LL via OTA.
But suddenly (I installed a few apps) it started increasing the idle consumption.
I'm going to factory reset the tablet and turn everything off to see what happens (I have nothing important yet on it as I was just learning how to use it and hesitant about rooting ir or not, finally decided 'Not yet').
As I'm not rooted i feel there isn't much I can do about it (On my old S2 i use Greenify, Amplify, App Quarantine, Disable Services, etc.).
If somebody else have info regarding idle battery consumption on stock and non rooted I'd really appreciate it (Wifi off, location off, sync off, etc.)
Best regards
Mariano.
before I rooted and flashed cm I was only getting 2% drain overnight just by turning on airplane mode.
You could also try turning on ultra power saving mode before you sleep, I think it said it has something like 140 days battery life when I turned that mode on at full charge.

I tried it during the last 24 hours and the battery still drained 6% by sitting on my desk in ultra power saving mode. I think this mode reduces the display which drains less battery but I don't think it has any effect on the processor itself. The wakelocks still happen.
I'll try the airplane mode for the next 24 hours but I fear it won't do much.
Oh my God!!!
Airplane mode during 24 hours. Battery drain result: 0%
How can this be? I remember once trying to simply disable WiFi and it didn't change a thing. I don't understand why activating airplane mode changes anything. Could it be that with WiFi off, Android's system still tries to access stuff (creating wakelocks) but, in airplane mode, it completely halts all data related activities (halt related wakelocks)?
I'm truly astonished by this test. Thank you very much Pleske for that suggestion!
Next test: Airplane mode on with WiFi on.
Airplane mode with WiFi enabled still drained 6%.
I installed "Timed Toggles" (https://play.google.com/store/apps/details?id=uk.co.ergodicity.timedtoggles) to automatically enable Airplane mode and disable WiFi at midnight. It's still not as impressive as the iPad, but it's incredibly better than losing 11% each day.

Um...... well 3 small things.
1 Turning on wifi after you turn on airplane mode makes airplane mode pointless unless you also go around with bluetooth on all the time since on the t-800 those are the only 2 radios the tablet has.
2. Odds are you are getting attacked by the battery saving feature of the interactive governor that the galaxy tab s uses which when woken up instantly cranks the processors up to 1.9GHz to help deal with what woke it up and to be ready to be snappy and handle what ever it is that you want to do, unfortunatly if you are asleep it runs like this fpr a bit then goes back to sleep. Get enough annoying things telling your cpu "hey hey look at me... I need you look at me" and you get some drain happening. Not sure how the ipad handles waking up but it does have a far less powerful and therefore power hungry processor to wake up.
3. Greenify still works even if you are not rooted and do not have exposed, it just does not do as many things automatically for you and can not handle Samsungs very important system bloatware for you. You can still stop the apps yourself or freeze them yourself.

1. I remember trying to disable WiFi (not enabling Airplane mode) and it didn't change a thing. For some reason, activating Airplane mode does have a dramatic impact compared to just disabling WiFi. Bluetooth has never been activated.
2. iPad's CPU vs. T800.... good point. That should be a good reason why iPad's battery seems better but is it enough to justify T800's 6%/day? I wonder.
3. I do have Greenify installed and set up for a couple of apps. As for bloatware, I disabled all those I could think of.
Ipad 1 -- 1 GHz ARM Cortex-A8
Ipad 2/3 -- 1 GHz Dual Core ARM Cortex-A9 (different gpu though between the 2)
Ipad 4 -- 1.4GHz Dual Core ARM processor
Those are the regular Ipads the Ipad air 2 comes the closest to the tab s with a tri cor 1.5GHz processor
That is just the differences with the processor when you also factor in that IOS is a very regulated system of what can and can not be installed, what apps can make what system calls, and general management that makes Apple very annoying for a PC makes IOS a very fast responsive and stable OS for phones and tablets even with much less powerful hardware. It is the basis of the difference between a specialized and a general computing platform. Apple products will get better battery life on average and be more compatabile with less issues then android until (and I would hate it if it happened) Google makes one device with only slight differences for screen size or storage and that is it. Also all apps would have to come from the store and be screened far more then they currently are.
The big advantage android has is with root and custom roms our performance increases where as jailbreaking ios devices either keeps performance the same or can even degrade it.
Apple products have amazing battery life in general. Maybe except for Macbooks (non-air), which still have great battery life. Apple's phones, tablets, and MP3 players have amazing battery life compared to similar products from other brands. I don't know what they do, but there's some magic to their battery and power consumption. I'm not surprised every Samsung device I owned had lower battery life than it's contemporary Apple equivalent.
iPad Air 2 vs T800 specs relating to power consumption:
mAh: 7340 vs 7900
Cores: Tri 1.5 vs quad 1.9 + quad 1.3
RAM: 2 vs 3

Hey Guys,
you have also a massiv battery drain on your Pixel Device?
I need to charge it twice a day since I updated to Android 13 ...
Do you think Google will fix it asap?
There are a ton of battery life threads in this section - more than one page of search results. I know battery life has been mentioned with regards to Android 13 in some threads in this section, although I'm not sure if it was in a battery-specific thread.
For what it's worth, I haven't noticed any difference on mine.

Have you checked to see in the battery usage what's using it
I had this problem before. The fix was completely wipe the device then install everything from scratch, not using restore service. Additionally, I putting background restriction on many battery hungry apps like Facebook, Messenger, Google Maps, etc... Also, I'm using Kirisakura kernel on top of battery restriction. My battery can last up to 22-23 hours.

Try disabling the Physical Activity permission of the Samsung Health App, it might actually do wonders when it comes to battery life. While it wouldn't affect your watch, your device would no longer be able to count steps [for me, that was worth the trade-off].
the answer is bluetooth and wifi failure and trying to reconnect NONSTOP. after 4 factory resets my phone suddenly doesnt do it anymore and battery life is fine. came to this conclusion when i connected my galaxy watch to my phone and is disconnected every couple minutes. looking at the quick settings id see bluetooth looking like its resetting itself. i didnt check the crash log but at this point its kind of common sense what it was. after some research last night i saw i wasnt the only one. it actually was so bad that my phone died over night even tho it was 43% when i went to sleep
https://www.reddit.com/r/GooglePixel/comments/wrfqze
I had my first full day with A13 yesterday and it was hard not to notice how fast the battery was draining, I would have expected this to have been picked up during beta testing
Less than 24 hours since update and I noticed it too.
My Pixel 6 used to be awesome in terms of battery.
But today, after 9 hours it's 30%. It's been some heavy usage, but it should be 50% at least.
Edit: The second day things went back to normal. After 16 hours i'm still at 66%.
The battery drain is bad for the initial 3-4 charge cycles, then it goes back to what was "normal" on A12. Which sucks, since if you listen to YouTube (downloads only, screen off) and use Google Maps while snapping photos (20-30 and no video), the phone will die in less than 8 hours.
In other words, the phone is unfit for travel. Pitty, because the camera is great.
You would think that now that Google has better control over the hardware and complete control over the software (including services), plus a huge 5000mAh battery, the P6P would do far better.
Sure, it's better than my last Pixel, a 3XL, but that was so bad I swore off Pixels.
The iPhone 13 Pro Max lasts twice as long with a much smaller 4353mAh battery. Without having to turn off 5G or regular services. What a joke.
SITREP !
Bluetooth issue still ongoing and still causing the major battery drain. Has 0 to do with what this guy said ^ . Sometimes its OK but most times it just crashed and restarts.
I dont have any of those issues. I guess I got lucky.
43% and it died overnight? Dude that is insane. Even if it is Bluetooth/wifi keeping the phone from truly going into deep sleep, you wouldn't think that alone would be able to completely drain the battery to 0 over the course of what... 5 - 8 hours? (Unless your my ex, then it's more like 14 hours ). Have you pulled any logs or looked at the battery usage? I'd be hesitant to believe that there isn't more going on there contributing to the massive drain. Gotta love google... I remember the first talks of Android 13 was geared towards smarter battery usage. Go figure.
Today my phone has been (and is yet cause the battery is not charged) plugged to a google charger for 3 hours and half and the battery has charged from 40% to 82%
The phone had the screen off for 1 hour by this time. This was when the battery recovered 40%.
I tend to think that we've got, Houston, a big problem here...
No massive battery drain for me. 8.39%/hr active drain and .80%/hr idle drain on stock kernel. Active drain is a little higher than usual for me, probably because of rebooting many times doing stuffs.
Fast charging is also the same for me using an Anker Nano II 30W charger. No problems in that area.
I have no solution, but I can confirm this is an issue. I had no issue before the update lasting up to even 2 days with light use. Now, I even with battery saver turned on, it dies in about 6 hours in my pocket.
I just went on a trip to Toronto last week and it was terrible, had to keep my phone powered off in my pocket so I could still be sure to have enough battery to get an uber back to my airbnb.
So far today at work. I unplugged my phone at 730am to leave for work, it's 1105 and typing this out is the most I've used my phone. It is both warm to the touch and the battery is at 73%.no wait 72% it just went down...

So far today at work. I unplugged my phone at 730am to leave for work, it's 1105 and typing this out is the most I've used my phone. It is both warm to the touch and the battery is at 73%.no wait 72% it just went down...

Here are 2 examples showing the difference between before and after A13
Just when I was about to switch to my P6P, I'm reading all these problems with slow charging and mediocre battery life. I wonder how widespread they are?
I can't use a new phone that seems to have a worse battery life than my P4XL...
Not to mention the whole sideloading apk FC thing.
Guys, I am also having massive issues with my new Pixel 6 phone which is approx 10 days old only....
A12 was fine for the first days then I want to A13 and then all hell brooke lose The battery drain is awful and I am facing these problems :
- Phone idle is between 20-37% - even when phone is in flight mode for the night it consumes 20-30% instead of normal 1-2%
- Viber is draining battery with 20%+ consuming when its not really used shows usage of 20+ hours Never had such issue.
I am over now 4-5 recharge cycles and I have turned off adaptive almost anywhere... What to do?
Just pray and wait for Google to drop a fix/patch for A13 for our Pixel 6 ???
For those that upgraded from A12 to A13 and having the issue, have you wiped the phone (factory reset) and started fresh? I know it's a PITA getting everything setup again, but that's crazy. I was at 100 percent at 7 am, now 7 hours later, I am at 66 percent with pretty heavy usage... Generally YouTube constantly along with everything else I'm doing. By no means is my battery life amazing, but def comparable to A12 on my end.
