Hi!
So I have updated my unrooted Note 2 to version 4.1.2 and below describes what happened:
1. Battery drain very fast, can't even last 24 hours. The battery details show "Android System" chugging all my battery juices.
2. On 2nd day, I tried "Factory reset" on Settings menu but still my battery drains very fast by "Android System".
3. On 4th day, I installed Kies on my PC and did the "Firmware Upgrade and Initialization". Noticed an improvement in battery life but after 4 hours, I noticed "Android OS" is now taking his turn to chug all my battery juices.
4. On 5th day, woke up and noticed battery drained >20% by "Android OS".
5. 6th day (today), I did another "Firmware Upgrade and Initialization" on Kies and now I noticed "Android System" took over and took over >29% battery usage in under 1 hour.
6. Now, I am running "Firmware Upgrade and Initilization" for the 3rd time and is hoping for the best.
Question:
Should I root my device and downgrade to 4.1.1? Before update to 4.1.2, it can last almost 2 days.
Thanks for your help!!
I had a similar problem and discovered that "gpsd" on my phone was causing the drain. This system also required other systems whiqh together used about 45% of the battery. The "gpsd" is the system samsung uses to track your phone (if you have enabed it). It did not cause this drain on my phone prior to the update.
I hope this helps.
Thanks...

Hey thanks for your input. Would you be able to explain in more details on how to disable this "gpsd" thing you mentioned?
I would like to try it out myself
I disabled all samsung apps, and several others including google now and location services.
Still a massive battery drain.
Very annoying..
it is said 4.12 drain faster than 4.1.1

I hope Samsung fix this issue, and quick! I don't like my phone losing a minimum of 20% overnight.
I have no battery drain issues (yet) on the 4.1.2 could be just the vocal minority experiencing it or idk.

On average I also don't observe a significant overall battery drain. Am currently projecting about 7-8 hours of screen time which is about the same as with before. Also having the same very low overnight drain.
However a few oddities:
Android system is higher on the battery charts than in 4.1.1.
I was playing nfs_mw before and after the update, and there is a significant increase in battery drain in 4.1.2. A full battery used to give over 4 hours of gametime, now gives just over 1 hour.
I've also not seem anyone else mentioning this and I'm not sure if this is related to battery but:
4.1.2 is absolutely perfect butter smooth
Every animation and transition had been completely fluid and going from 4.1.1 to 4.1.2 was like upgrading from 50% to 100% project butter.

Mine after upgrade to 4.1.2 took 7,5 hours during night to drain battery to 89%...
On 4.1.1 it was about 3 - 4%. I'm downgrading...

why is that?
I have downgraded but version 4.1.1 doesn't give me the option to switch to 2G only data mode!! Only 2G/3G/4G or 3G only!
This is essential as where I live my 3G keeps cutting out, and I get frequent loss of service. Is there any way to get this option back???
Roughly about 1% per 7-8hours depending on the current battery level, are you losing more ?
I downgraded to 4.1.1 by downloading the appropriate firmware from sammobile.com and flashing as pda with odin. I then flashed the perseus kernel which has the sudden death bug fix built in. Perseus is not prerooted but it doesn't have to be, at least it protects the phone from sudden death as I had the faulty chip in mine. I got 40 hours standby and 4 hours screen on out of it now, all accounts syncing with Google now and Samsung tracking service. happy to have switched back to 4.1.1, all I miss is the snappier s note from 4.1.2.

Hello guys I have this problem also In my note 2 after updating to 4.1.2 my battery drain like 10% for 20 min in idle
Factory reset dosen't solve the problem
I just wipe data and cache from recovery mode beleive me now its better than before I am using it for 1 day 14 hours I still have 49% on heavy usage with H+ connection

Hope it get fixed soon...
Last night I disabled "Google Location Services". It is under Settings > Accounts > Google > Location Settings
This is what I noticed.
Before I sleep, after I finished charging at 16min my Android Services spiked up almost 50%...
When I woke up, this is what I saw... 9% total drain and Android Services went up to 54%...
Not too bad comparing to a few days ago when I first updated.
So is there anything I can do without needing to root my phone?
Thanks!

I have the same problem like You
Can confirm this issue. Used to get 5-6 hours screen on time on 4.1.1 on a normal day (moderate to heavy usage).
Now I can't even reach 3 hours on 4.1.2. I already did a hard reset. No change.
Can installing a custom ROM solve this?

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core
Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?
OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.
I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

Just wipe Battery stets after flashing. It needs few complete chargings to calibrate the battery.
There are also many apps in the market for this

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?
So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.
Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...
Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?
Bone stock, not rooted or rommed.
My battery life used to be phenomenal. I would check at the end of basically every day and averaged 4-8 hours of actual Screen On time. The Screen would account for 40-55% of the usage, followed by all of the*apps*that I had used that day. Android System and Android OS would be pretty far down on the list.*
Now that I have 4.1.2, I'm lucky to hit 3 hours of Screen On time. And now Screen, Android System, and Android OS are accounting for 20% EACH.
I haven't changed any settings or the way that I used the phone. The only thing that has changed is the update.*Is anybody else experiencing this?
I've gotten bettery battery life since 4.1.2, significantly better. Try to perform a factory reset or it could be a faulty device.

Yep and I have more or less tried everything including tweaks galore, every suggestion I coukd find, and freezing several dozen apps.
Nothing can be done about this and my guess is Samsung have made an absolute mess of the update. My HTC loses maybe 1% overnight on a bad day, this loses way over 10%.
I'll prob end up switching back to 4.1.1 but unfortunately it doesnt have the tap to reflow feature in the browser (which I use a lot)... I wonder if I can remove it via titanium and restore the newer version which would have reflow on 4.1.1 ??
I have the same problem. As soon as I took my phone off the charger this morning it dropped to 99%. On 4.1.1 it used to last for a good 20 minutes before dropping to 99%. Also last night after about 6 hours of screen time Android System was at the top of my list. And that is with 20 or so system apps frozen or deleted from running.
What's the easiest way to go back to 4.1.1?

Well I dunno.. I have tried everything and there is definitely a battery drain issue. If it is caused by ebay/whatsapp + facebook, then I'm curious as to why they don't show up in battery usage or betterbatterystats... and I'm also curious why the exact same setup on my HTC EVO 3D does cause these horrendous idle battery drains.

Yeah already done all that and there doesnt actually seem to be anything using over like 5%.. I have elimated the higher one yet it still drains ovwr 10% at nite. Or in general idleness.
What I became accustomed to with my previous phones was 0% or 1% drain over many hours if the screen was off. Not 2% or more an hour.

That's specifically my DBT rom (stock everything as well) and I've had battery issues and to be honest, it's still better than most other phones, but I'm getting about 40% less life out of my device now.
I have flashed again, I've reset, and deleted everything and still no luck. It's something with the ROM. I hope the next update will fix it. If it doesn't, I'll revert back to 4.1.1 because I would go to bed with 50% battery life, now I have to charge in the middle of the day if I want to get through a long work day with lots of use.

Hey guys
I recently upgraded to 4.1.2 and it's been causing a lot of battery drain.
Googleplay magazine app was taking about 28%,so I disabled it and now "Android system" is doing the same thing. I also have disabled GPS/location services and google now but it hasn't changed.
Any tips?
You CAN NOT do anything to reduce Android System usage. So if no app is causing major wakelocks and it's Android System only then you can't do anything but to bear it.

If you have a powerful device, expect battery to drain fast unless you do battery saving tips. But for me I bought this beast to maximize its potential so its ok for me if battery drains... thats why it has a removable battery compared to the norms now which is non replaceable ones...

I'm reading in the forums here about people achieving 1% battery drain on their Galaxy Nexus. This seems so out of reach for me, I have no idea what's going on.
Basic Stats:
Carrier: Sprint
Android 4.1.2
ROM: AOKP
My phone has always drained at least 7% battery per hour (even before I rooted). My mother has the same phone and hers drains 2%/hour. I took my battery in to get tested and they said it was in excellent health.
Last night, I put it on airplane mode at 100% charge and woke up with it around 33%. Android's battery stats attributed 70% of the drain to "phone idle".
I've used BatteryCalibration (no effect) and disabled almost everything. Better Battery Statistics isn't showing any significant wakelocks (log attached). So, long story short, I'm baffled. Is this defective hardware? The phone is hardly usable as much more than a tethered doorstop.
Any thoughts? I really appreciate it.

I wound up unrooting, re-stocking and re-locking the phone last night. Same issues. Took it in to a sprint store today and they definitely agree that I've got a hardware issue, not software/kernel.
I'm going to start getting in touch with Samsung's warranty department.
I received my S6 Edge on Wednesday and rooted it the same day via Ping Pong. I'm on G925TUVU1AOCG. Is that even the latest version? Anyways, battery life is literally ****. I can't get more than 2 hours of Screen on Time. Even my Galaxy Nexus from 2012 gets at least 2+ hours.
Is this because I'm not on the latest version, rooted, or something else people have experience with?
I've had horrible battery life since I've rooted using ping pong this week. I don't think my phone is going into deep sleep but haven't checked it yet. It drains fast when not being used.

I went through this issue with my first S6. Re-root and download better battery stats - or CPU Spy. See if your phone is going into deep sleep. Mine was constantly kept awake by lli_pm_wlock. I couldn't find ANY information about it on the internet - but it was keeping the cores active and burning through battery like crazy. It would occasionally enter deep sleep, but only for a few minutes at a time.
I ended up returning the phone and getting my new S6 Edge. I tried everything - factory resets, flashing stock firmware via Odin, basically everything possible without tripping KNOX with a custom kernel.
My battery life has been awful. Specially after rooting with Ping Pong and specifically last night. 100% at 10PM, and at 11AM with 58 minutes of on screen time, the battery was at 13%. That is just horrible. Worst battery life I have ever gotten out of the phone.
Pains me to say it, but if the battery doesn't improve by unrooting it, and waiting for a future update to 5.1, I'll most likely change to a LG G4.

If you have it rooted install Better Battery Stats and figure out the problem. If it's a wakelock, the problem is it's just not going to sleep. Something is keeping the CPU active even when the screen is off and nothing is going on. It's a common problem on the rooted phones - but usually PingPong Root doesn't have the issue. Enter recovery (turn off - then power, vol up, home at the same time) and clear the cache. Reboot and run BBS for a while.

I received my S6 Edge on Wednesday and rooted it the same day via Ping Pong. I'm on G925TUVU1AOCG. Is that even the latest version? Anyways, battery life is literally ****. I can't get more than 2 hours of Screen on Time. Even my Galaxy Nexus from 2012 gets at least 2+ hours.
Is this because I'm not on the latest version, rooted, or something else people have experience with?

I also have the same experience but instead I just keep my phone on Ultra Saving mode
It's been really difficult for me to try to drain my phone to see my average screen on time.
But is this normal? I'm not sure what is a decent Deep Sleep percentage.
Btw: This is after I unrooted without factory reset.

Yea we're having very similar issues. I would try the G4, but the Edge is too beautiful!! This is the first time I've gotten a phone so soon after release, so I'm probably gonna stick it out for a month or 2 and wait for bug fixes.

So I purposely didn't charge it last night, and you can tell it has really really bad standby time.

Try disabling WiFi or set it to keep it on only when plugged in.

That is not normal. Backup your data and flash stock firmware with SmartSwitch then restore what you want. See if that makes your battery last any longer.

I had horrible battery life when I got it out of box. It wouldn't last more than 5 hrs with very little use. After I flashed stock firmware with SmartSwitch, Battery+ RAM Usage issue got solved. Now I get whole day with single charge. I take my phone out from charger by 7 AM and by the time 10 PM in night, Phone would still have 35-40% battery left. I get many emails [50+], 2hrs of GPS+Music streaming + random facebook & Instagram and even after this, I get good battery life. So I would 1000% recommend that you do a flash stock firmware with SmartSwitch.

I tried using SmartSwitch and unfortunately, battery life was only a tiny bit better. However, I started getting a bunch of force closes, and the phone became laggier than before. I would try it again, but it's so much work resetting up my phone! ...especially without root.
So I ordered the G4. Hopefully I'll be getting the Note 5 in a few months .
