[Q] 4.1.2 battery drain

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

Much much faster
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?

Android System and Android OS draining my battery since updating to 4.1.2

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.

I had the same dreaded android os battery drain issue after updating to ma8. Used to have great battery life before that. After freezing Google search, Google now, still no use. Then i realized I installed another weather app at the same time I upgraded the os. Bingo. Un installed that offending app and that fixed the Android os battery drain issue. Hope this helps.

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.

well the new french 4.1.2 N7100XXDMA6_N7100OXADMA5_N7100XXDLK7 is much better than the last one rlsd in december and my battery drains less now

i also have same problem on XXDMB2 .i think only some people have battery problems with 4.1.2. Is it related to emmc firmware 0*1f ? Is the kernel reparing the bad sectors by itself? and what is kworker process?

[Q] Suddenly Terrible Battery Life

hey guys, recently with my Rogers S3, my battery life has become terrible, and I would like to figure out why.
if anything, I have been using my phone less than usual, with it mainly just sitting in my pocket unused while I am at work, and getting terrible battery life.
the phone is rooted, but other than that it is stock, running 4.1.1
I used to get around 24 hours(7am to 7am) on a charge(unplug in the morning before work, go out at night, not plug it in at all, then the next morning on my way home plug the phone back in with a few % of battery left), then all of the sudden it was down to being dead in 7-8 hours(7am to 2-3pm).
a few days ago, I installed the Snapdragon BatteryGuru, and that has gotten my phone to around 9-10(7am to 4-5pm) hours of run time, but still very terrible compared to what the phone was getting.
any tips for how I can figure out what is causing this faster drain?
thanks in advance

Looks like its searching for signal, Samsung account sync maybe, and Google is syncing something. I'm not good reading those...but what's syncing under your accounts menu ?
So sec.spp.push is Samsung account push notifications... At 225 wake locks yuck. Unsync that, turn off other ones like Facebook or ibaaw groupon on there.

[Q] Draining 7.5% Battery per Hour on Airplane Mode

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.
Thanks,
Jeff

reflash your rom.
or better idea, change the kernel, i suggest AK

I agree battery life is improved significantly on the latest ask kernel but my self I would reflash the ROM too

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.

[Q] Battery Life Issues

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.

Yea so I flashed the stock ROM with Odin and unrooted. I didn't wipe data however. But battery life still sucks. For anyone that cares .

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.

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.

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 .
