Most likely you face the max frequency bug. See the respective thread.
Proximity sensor is really far on the left side so it's hard to trigger.
Btw, I suggest reading through the forum before asking because this has been discussed to death already here

Do you face these issues even after installing September 2018 update?
Try to update, proximity sensor issue is most probably solved by this update.

Battery Instability

Nowadays I have a weird problem. Even though I fully charge my phone, it behaves like battery is empty. It happens in two way:
1. After some usage, it can occur at 15%.
2. While showing battery is charged enough, you restart the phone. It starts as ciritical battery level.
3. For case 1, it can happen at higher levels as well. Screen starts flickering then phone shutsdown suddenly.
I tried calibration apk. I suspect it caused some problem also.
My system was stock 4.1.2 leak. I thought it may be reason, so I downgraded to ICS. But, I still have same problem...
Any1 has an idea? Battery or phone has problem or not?
Edit:
I opened back cover now. I am very surprised. Battery got deformed. Middle part became thicker. It cannot fit to battery slot.
I think god saved me. It could explode.

Hopefully new battery will resolve the problem

[Q] Battery drain, who's the guilty?

Hi guys,
I've a XT1068, does anyone have the same problems with the battery?
I was not using my phone where the battery started to drop like that. I charge it, then unplug it and then went to bed.
Yes, I've wifi, bluetooth and 2 SIMs with one of them with data always on.
See pics attached.

Same for me. When I bought the phone I immediatelly upgraded to 5.0.2. After upgrading, I did a factory reset through Recovery. Android OS and Android System eat up most of the battery, whereas in normal cases it should be screen and standby (and perhaps some fewquently used app).

Looking at that first screenshot of the battery chart it looks like you have an alarm or wakelock keeping your phone awake when it should be sleeping. Take a look at my Moto G 2014 battery guide

Well that guide is great as a general recommendation. However, what we have here looks like a bug. Android OS and Android System should NEVER take more battery than standby and screen.

You are right. And I see that in my xt1032 that still runs on KitKat these wakelocks do not exist. Could this have to do with data wiping? I factory reset the phone from recovery AFTER the 5.0.2 OTA update. AFAIK it fully wipes data and cache.

It does. Install BetterBatteryStats from here and run it for a while. It'll give you details on every wakelock and alarm on the device and how much battery it is using. Then you can use amplify in the tutorial I linked to earlier to configure the wakelocks so they are not consuming as much battery.

Thanks a lot Duck86, but I think that for a brand new phone I should not need to do all these things to get decent battery life. As I said my old xt1032 on kitkat was is to handle two days of significant usage and most of all, if you did not use it the battery did not drain. By the end of the day, battery usage was topped by standby, screen and perhaps an app with frequent use. On top of that, 5.0.2 looks generally unstable compared to the utterly robust 4.4.4 that runs on my xt1032. I get noise and lag in call sounds for example, issues that were not even imaginable on xt1032/kitkat.
So I think I will try to fall back on kitkat. The problem is that I do not know which stock ROM I should install.
My Baseband version is:
MSM8626BP_1032.3105.93.00R EMEA_DSDS_CUST
My kernel version is:
3.4.42-g48d3b85
My system version is
22.21.28.titan_retaildsds.retaildsdsall.en.03 reteu
Build number
LXB22.46-28
Any clues?
It's probably gsam battery monitor that is doing all the wakelocks to gather data.

Nothing special, depends on what you were doing. To have a clearer view: Load your battery until it's full and let the phone rest for one or two hours. Make some screens than. You can see what kind of wakelocks disturb the sleep mode of the device.
"Who is the guilty?" Motorola?..
Guys you know about the bug with the gps? When you turn on and off the GPS on the stock rom and the GPS remain on and kills your battery until you restart the phone? Took me about 2 weeks to figure out.

Why does this happen?! Battery annoyance.

Just when I think I've got it all setup nicely...
Latest AOSIP rom with Hellscore kernel, stock settings greenify, full discharge and recharge, all seemed so good....
And then boom. Go to reboot to recovery and I get the little empty battery icon upon reboot - but I was at around 40%?!
I use the battery calibration app, for what it's worth knowing the debate about the battery stats file. I've done the bootloader logs 'trick' and still I get a random occurrence like this?!
Anyone else been plagued with this randomly happening to them?
There are so many reasons it can happen. on thing id recommend is install ampere form play. Using this you should be able to monitor the voltage of the battery and at least know that it is operating within the correct range. if your 0% voltage is too high, it could rule some stuff out.

Cool. Just periodically check the app and jot down the percentage and voltage. keep doing that until its ready to shut down. preferably a reading every 10-15% if you can but really important is to try and capture readings just before and after any drop off you may see.

Perfect thanks for the advice, I've got it installed and now juts doing a full charge.
Following that drop out, the device then reported 7% battery so I let that go flat and now fully recharging.
If it's the case that there is something going on here, how can the issue be corrected? Does Ampere help configure reported VS actual readings, or does it purely show what's being drained?

Its worth getting a voltage reading now too then, to see if it is as low as expected. As for solution, we need a root cause first.

Ok here is my first screen. I'd browsed Facebook (web version) and watched a video or 2, battery dropped to 97% soon after.
Yep. Just keep going. Every 10% is fine. No more than that. Actual battery charge is voltage so we just want to see if there are any conflicting data sets later on

It just did it again!!?
I had even doing the Ampere monitoring but didn't go all the way down. But today I just experienced the random drop out again. Strangely when I booted back up, it was as if the cache had been wiped as the Android Optimising app screen came on.
This was from the other day though, if this helps?
The other day did it seem to deplete normally? I'm around 20%/right now and see similar voltage to you.
Sometimes my phone used to crash and when it booted up I had this graph / drainage issue. It's as if it goes into some manic sleep that kills everything. What you've got here seems similar. I don't think there's an issue with the battery cycle itself.
I'd be tempted to do a factory reset and start clean to be honest.
Is the back of your N6 lifting away from the frame? I had this issue too and ended up doing a RMA because the battery was bulging.

Just took off my case and checked and all seems normal, back doesn't appear to be coming away and seems to be ok.
It's times like this I miss my good old Note 3, never had a battery life like it for its flat lining ability!! (see attached)
If it were the battery capacity due to bloating, I would expect to see the Voltage value to be wrong
Go back to stock and run it with no restored apps / data. If it still happens RMA

Your battery calibration is messed up. It happens.
DO NOT waste your time with "battery calibration app" -- there is NO software you can install and run from Android that will have ANY impact AT ALL on the battery calibration. All those "battery calibration" programs do, is delete the battery stats file, and all the battery stats file does, is store a log of what programs are responsible for how much resource utilization -- nothing at all to do with calibration.
Battery calibration reset is done through the BOOTLOADER.
Reboot your phone to bootloader. Scroll to "bootloader logs". Press and hold power button until the phone shuts down.
And that is all there is to it.

Thanks for the reply.
Unfortunately, I have tried this many times and so there must be more to it than this. On my latest rom, I had wiped phone and clean flashed whilst phone was connected and at 100%. Therefore a new clean install whilst phone was at 100%. I cleaned that stats (for what it was worth) and also did the bootloader logs trick. I would have thought that would have solved the issue, but as reported it still happened.

Your calibration is fine because the % matches up to the voltage, which is all calibration matches.

It's hard to say. It seems like the system may be crashing or something at that time and causing an inordinate drain. Thats what mine used to do sometimes.

Mi Mix Screen went out

Hi everyone!
I've been using split screen feature quite often, but when I placed it under sun today with this memory consuming feature, it turned slow and after 5 minutes, the screen went out. Still can hear the rings and vibrations but LED isn't coming back.
Can someone please help me how I can work this around, any shortcuts or hardware DIYs?

Brand New Pixel 5, battery seems awful

I upgraded to a Pixel 5 because my Pixel 2 XL was experiencing hardware issues and was going to die. Among them were battery degradation that was leaving me with maybe 3 hours screen on time from a full battery.
The Pixel 5 so far has been barely better. Additionally I went to bed last night with about 79 percent battery, I woke up around 48 percent. I have no idea what's going on but this is fresh out of the box, I got it Thursday like everyone else in the USA. Is this normal? Can anyone suggest how to figure out what's causing this drain?

I loose 4% overnight. Maybe an app is running in the background. Check WiFi for poor connection or background scanning.

You might wanna FDR and start fresh. Sounds like something might be hung up from the setup. All reports about battery have been stellar so far.

I did do the setup where you transfer data from your old device. I guess maybe I need to bite the bullet and do it fresh.
Do you know anything about the... I think the setting is called Always On Display or something like that. The setting where when the phone is locked and the screen is off, it always displays the time and notification icons. I had it on my Pixel 2 and it worked great, it's almost necessary for me at this point. I have it turned on also on the 5, but it seems...finicky? At times it shuts off, especially at night. I used to keep my Pixel2 on my nightstand (just laying flat, not on a stand or anything) and the time would be on all night so I could see it at night if I woke up. With the 5 it seems to shut off in the dark. Additionally periodically during the day it sometimes all of sudden jumps to really high brightness, then back down to dim, sometimes it turns off completely and I have to hit the power button or the fingerprint reader to unlock the phone. Even doing the tap to wake doesn't work. Actually that double tap to wake doesn't seem to work at all regardless.
Any info on any of those issues you know about? I've been searching around and I've found basic references to some stuff with that always on display but no direct threads or anything specific.

Not too sure about AOD, I just went with defaults. But last night, my first with the P5, I unplugged at full charge and 7 + hours later it was at 100%. That's never happened but it was face down and on DND. Nonetheless, check out this thread, download the app, non root needs certain permissions, and let it run for a day or so. It should show you what you need to know.
https://forum.xda-developers.com/showthread.php?t=1179809
Did you make sure to charge the phone to 100% before using it??? These lithium ion batteries need to be charged to the max if you want them to last. My pixel 5 wasn't even fully charged it was somewhere around 65% out of the box. I would leave it charging for a half hour or so once it hits 100% just to be sure.
I mean.. this is mine.

That's incredible. Next time include all 3 screens please. I could get 12 hours of on screen time all on wifi. Let's see you get that on 5G.
Real world battery is best.
I'm seeing great battery life like many others.
I started using AccuBattery Pro. How accurate is the estimated capacity given by the app? Anyone have any experience?
For me the app is estimating battery capacity to be 4,490mAh which is obviously way above the advertised capacity.
Coming from a worn out pixel 2xl this 5 is fabulous the battery is great. I accidentally left the flashlight on for an hour and it barely drained it. The battery is exceeding my expectations. Screen on time at 5 hours and I'm just at 49% with 10 hours remaining. I'm satisfied for sure
Also on Verizon, but no issues for me. Battery life has been amazing, I didn't charge last night (unintentional) and I was going until this afternoon, with mostly light usage. I've never experienced something like that before.
So in case anyone is interested in this, I actually have a hardware defect that was discovered by a user on reddit.
Link Here
The gist is that the proximity sensor is (i think) detecting that something is up against it all the time. This creates issues with things such as the phone screen not turning on when you pull the phone away from your ear when on a phone call, Issues with tap to wake and lift to wake not working, and Ambient display/always on display (whatever it's called now) constantly changing brightness and/or shutting the display off completely. Literally the phone could be sitting there on the table and all of a sudden the always on display goes to max brightness, then down to dim, then up, then shut off completely. I assume all this craziness is hitting the battery hard.
I am trying (although frustratingly) to get Verizon to exchange it for a new phone. My phone acts exactly like in that thread. There's a proximity sensor app that will detect when something is near it and change color. Mine is solid colored and won't change unless you press on the glass near the sensor. Just in case anyone else has this issue come up, there it is.
I'm at 5 hours of screen on time and 17 hours use. The battery is exceptional and I can dedicate more time to work online because of it.
It sounds like you have ported a troublesome app over from your old phone to be honest. I think a factory reset would fix it.

Mine says 3,900mAh and hasn't changed for two weeks, which irritates me. Battery life is... okay.
Curious
I'm losing apprx. 6-10% while I sleep. seems a little excessive compared to other testimonies. I have to usaul social media apps, messeging apps no gaming, no AOD.
Any insight is appreciated.

I just finally got my replacement last night from Verizon. Too early to tell if it fixed my battery issues because I had to set everything up and such. But If you have those issues, I would get a replacement. That's a faulty phone.
