i also got high android-system battery drain. i hope this will be fixed in the next update.

Mine is quite good so far. Easily get through 2 full days with 6+h of SoT. But I disabled alot of background stuff like health tracking etc. But android system is definitely using too much power on mine as well.
Btw just got an OTA update today. Version nr. ending in ......136 now.

Eva-L09, I haven't rooted yet but there are quite a few apps that you can disable/uninstall without root.
And Google services can be an issue too. I've read that wifi/bt scanning should be disabled in marshmallow. You can find them in the Google location settings in the advanced menu.
This is how it looks like for me after a full day (see attachment).

So far my battery last about 2 days, and SOT times are just under 6 hour when i looked the last time. Im very pleased with the battery

Got 5 hours

battery drain in flightmode
Hello
My P9 dropped from 100% to 30% in 8hours, over night.
- phone was fresh rebootet before
- in flightmode
- fingerprint options off
- display always off
something from the system/launcher/default apps is draining the battery.
Phone is new, original System, i just added a handful of apps like whatsapp, telegram and so on and the design for non rounded icons.
Greetings and thanks for any idea

I've lost around 15 percent overnight as well
Facebook running in the background a lot seems suspect though.
Overall battery life seems pretty good though
Although I have no idea why the chart is always so squashed to one side :/

Also getting two days here
Night time the drain is almost zero which is nice to see when I wake.

8 hours would be possible with extremely good signals and low brightness I would think. Good SOT, I'm normally at about 5 isch but then I've also have most apps running after the screen has gone of.

Battery life

Is anyone having battery drain issues?
I'm on the latest update, and it seems like I have to do a soft reset every other week to fix the drain, am I alone?

This is surprising, after the last update my Gear S2 has a much , much longer battery life.
Although, I have experienced issues in the past where the battery was being heavily drained by some of my watchfaces. If you go into your gear app, go into watch face.
In the top right corner you will see "my apps", go to updates and you may have watch faces that need to be updated to work more efficiently with the latest gear update. I would bet that this is the root of your issue.
If not resetting your watch should resolve the issue.

I'm having battery issues too.
Few days ago battery life was drained in 10, 12 hours. Since these day, every day the battery ends before the end of the day (middle afternoon).
I've performed a soft reset but it doesn't fixed it.
I've changed my whatchface but no effect.
All my apps and whatchfaces are updated.
I don't know what else to do.

Hello,
I have the same issue. I just got new gear s2 classic 4g gsm unlocked. When i connected with gear apps i has given me some updates and i did it. I noticed battery is draining a lot without using anything...

After some searches, I found some people that solved drain issues by performing a factory reset.
So, I dedided to try it and, good news, my issue has been solved.
I never will known what was the real problem, but now all is working correctly and battery life is as long as usually.
I hope this continues like now for a long time.

Hey,
so i recently found my gear S2 after my wife misplaced it a few months back. I updated it and immediately the battery started draining. Got about 5 hours before it died with little to no use. The next day i went in and deleted every bloat wear app that it would let me delete and turned off "Report diagnostic and usage info" in the gear info. and i've been using it for about 8 and a half hours now and I'm at 69 percent. It's only day two but i hope this helps someone out.

No I haven't moded it in any way. I haven't seen any advantages to fo so.

What is your battery life experience?

This is the second full day of usage that I am getting out of my Pixel 2 and the first day of moderate-to-heavy usage. The previous day I was at home, so I did not use it as much and I noticed that the battery life was not too bad. But given that I did not use it intensely, I cannot tell for sure. But today, I noticed significant drain in the battery during my morning commute. As an example, my battery went from 79% to 76-75% in a matter of minutes (about 10 minutes). This was very concerning and made me feel like the battery performance was not really much better than my nearly 2 year old Nexus 5X whose battery has noticeably depleted in capacity.
I don't know if this battery drain has anything to do with poor cellular network connection during my commute as it completely cuts off in many places, so may be I am draining more battery trying to connect to a network. Or may be it is due to using bluetooth earphones. But I want to get a sense of what others are noticing and how I can more carefully test the battery performance to get a clearer understanding about its performance.

Never judge battery life from a single day or two of usage. You'll need at least a week to see if the battery performance remains consistent.

Much better than my iPhone 7 that I switched from. Can't ask for much more than that. (never should have jumped to iphone 6 in the first place)

I certainly get much more battery out of my Xiaomi Mi A1 with Android One (Oreo).
Though 4-6 SOT hours in the Pixel 2 are not that bad, it feels like not enough in comparison to 6-9 SOT hours I get with my other smartphone.

I get at least a full day if I leave for work fully charged. Much better than iPhone. The best I ever got was 21.5 hours but that was only after having it a week.

Xiaomi Mi A1, comes with built-in Android stock, dual camera...bang for the buck right now, costs like 150-200$. You can check it out on xda, its battery numbers are impressive.
And installing Google Cam makes it perform great even in lowlight conditions, perhaps not very far from Pixel 2...
Enviado desde mi Pixel 2 mediante Tapatalk

I'm getting hardly 5-6 hours of SOT with medium to heavy usage. Battery capacity could've been bigger!

I'm not even getting 2 Hrs of SOT. I've had my Pixel 2 XL for a week now and the battery performance is abysmal. I have the screen brightness set to less than 50% and the phone is not modded or anything out of the ordinary like that. Thinking of formatting and setting up the phone again. This is so annoying.

Pretty crappy IMO. I can get a full workday but thats at min-med use.

What does "min-med" use actually mean? SOT is a flawed metric, but at least gives some standard of reference (though as people use different brightness settings, do different things with their screen on time, have different signal conditions, it's still not easy to meaningfully compare).
FWIW the one time I didn't charge mine overnight it ran for 41 hours, > 6 hours SOT, still 7% left. Of course I'm not playing online games on LTE at full brightness, and I'm sure it wouldn't last close to that if I were, but for my use (as a PDA, phone, browser, a bit of audio streaming and a bit of light gaming) it will reliably last a full day (not workday) with charge to spare. I don't see this phone's battery as a problem at all.

Alright, I gave this a few more days of usage. I am getting around 3.5ish hours of SOT with 30% battery left. Sometimes less, but around the same ballpark. I think I can safely say that this is significantly more battery than my old Nexus 5X, which I had to constantly charge throughout the day and still have issues with depleted battery by the time I reach home. So that's good!

For me the battery life is super, I didn't get such stats with my old OnePlus 3.

Poor reception is a HUGE drain on battery. Specifically, modems will try to search for service more agressively when they start nearing their poor signal thresholds. I have a friend who lives in an area that has just enough cell signal to destroy my battery! I always have to put my phone in mode when I'm at her house to save battery!

My battery life on my Pixel 2 is horrible. All radios off, full charge this morning, phone is completely wiped as I am selling it and its down 35% by doing nothing. No wifi, no sim, no apps, just on. Its garbage. That and the stiff buttons is a quick sell-off to me. Its a work phone so I dont really care. Having a much better experience with my moto Z2 play that i now use as a work phone (personal phone is a Note 8).

Sounds like a warranty issue. Did you try getting it fixed?
And how can you sell a phone that belongs to your employer?

Battery Drain issue with MI A1

Hi All,
I have been using MI A1 for 4 months. Everything went fine till March Security Patch, once I updated it to April Patch the battery drain issue started. To resolve it I took it to Service centre and after detailed analysis, they came to a conclusion that there is a problem with Battery and they replaced it but it didn't resolve the issue. I requested them to install Nougat as the last measure. With Nougat the issue the battery drain issue was resolved but it created a new problem of charging.
With Oreo 8.0.0:
Charging time: Approx 90 Minutes.
Screen Usage time: 2 hours. "Battery Drains excessively when the phone is at standby.
With Nougat :
Charging time: 6 Hours.
Screen Usage time: 4 Hours.
Can anyone let me know how to resolve the issue?

I have a similar case. I will add my information, perhaps it can help you (or others) towards the solution:
Used the phone on nougat, never updated, for about 6-8 months. Never had a problem, Deep Sleep always worked. Few days ago decided to try other ROMs.
I started with LineageOS 15.1, flashed it cleanly, but noticed that deepsleep was not working. Didn't tried to solve it, just went back to stock, this time I flashed Official Oreo (April Patch) with MiFlashTool.
Still Deep Sleep didn't work. I had no apps installed, and DeepSleep was not working out of the box with a clean flashed Official build.
Using "Kernel Auditor" app or "CPU Spy", I could see that DeepSleep was almost never used.
Using "Wakelock Detector [root]" I noticed that something called "7000000.ssusb" is waking the kernel very frequently, like 3 times per second!
On google, there's a lot of people with this 7000000.ssusb problem keeping the device from deepsleeping, but I couldn't find anyone that fixed it.
Additionally, I've seen a few people complaining about deepsleep/battery issues on latest builds of LineageOS (not many) and on RR (quite a few!).}
Good luck with this problem. It's really annoying ^^

My A1 is working completly fine with latest stock firmware. I use apps like Messenger, Instagram and more and I get more than 6 hours of SoT. No modifications made, no root, no custom ROM - everything stock. Maybe your battery has to calibrate or something? Actually my phone was draining for the first time I got it but after few weeks battery got much better and sometimes I get 7,5 hrs of SoT (depends on usage).

Do you use it in 4G (LTE) or WiFi, or which kind of connection?

suppose you have the mi a1 out of the box untouched and unmodified
and you update to oreo, and you want to go back.
can anyone tell me what are the steps that i need to follow?
download MiFlashTool
download nougot firmware
what settings i need to enter in miflashtool to flash correctly?
that 6hour to charge the battery is very bad

Maybe it's a charger related issue. 1 h 40 mins its normal.

Battery Drain issue with MI A1 | Xiaomi Mi A1
I was thinking of waiting for Official Oreo 8.1 and if still doesn't resolve the issue then I will downgrade to Nougat. If it works fine on Nougat then I will have to fight with Xiaomi to replace my mobile or to provide a permanent solution for it. The main reason to buy MI A1 was having stock Android experience.

I've read that 8.1 will fix some battery issues, so wait and try it out. Another question, what about your apps? Maybe you have a lot of apps running in the background and they might drain your battery.

Regarding the Apps there are no rogue apps. Because when I had Oreo reinstalled again without any apps the issue was still there. The beauty of Oreo is one time I see an app consuming more battery and then I uninstall it. The next time it's a different app. So apps have not made any difference.

My friend had a problem just like you, but after he changed the sim with another one from another network everything returnet to normal.

Try using brevent to standby or force close apps after they're closed using back button. Considerably improves battery life, at least for me.

O god 6hrs of charging time

System Update 55.0.A.11.25

Appears to have dropped today.. I'll update after charging. (Phone has lasted ~2 days on basic usage) See battery isn't too bad

I've been looking for a changelog or something to see what this update did, but couldn't find anything.
Battery easily lasts a day for me after quite average usage. Great little phone overall tbh

I've just got this phone today today. It updated and now my recent apps bit is always 1 blank white page
