[Q] GN2 Battery Performance Degradation after Update

Hello
I have a AT&T Note2 that I got late November. Battery Performance was fabulous. I just recently got the update to 4.1.2 OTA and there was some sort of upgrade or maintenance just prior to the 4.1.2 update.
I immediately noticed a difference in battery performance. It was substantially less than what I had on 4.1.1. I cant get any straight answers from Samsung or AT&T, there is no comprehensive log for the update so its hard to figure out whats going on.
Same software load as on 4.1.1. I did notice that after the update to 4.1.2 there were substantially more items in manage apps> running than what was in 4.1.1.
Samsung claims the root cause is the update to the OS and a change to the wifi radio and software.
Does anyone know what really is going on. At&T is a lost cause and no help whatsoever.
Thank you

I will be interested what you find out as I am experienceing the same issue. I went from 95% to 65% overnight doing nothing (WiFi on). Earlier today I was losing about 2-3% battery every 15 minutes doing nothing and did some research. All I could find out was to turn off all location services and since I don't get Wifi at work, turn off WiFi while here. This helped some, but still would like to find out what is going on. My iphone was a battery hog in the end of its life and my new GN2 lasts barely as long as my 2 year old iphone did. Not a happy camper right now.

Hi, I'm hopeful one of the Senior Members or Mod's will run down a answer as well as a comprehensive change add-delete and enhancement log regarding the 4.1.2 update. All I can say is I have not added anything my daily use is the same..no games. I disabled all the att bloat wae other than hot spots. I sort of paid attention to my running apps in 4.1.1, and now in 4.1.2 there are many more things theree that wernt prior to this update. I didnt have to disable anything prior to this update.
The answer is not in disabling bloat apps. The answer is in the log that shows what was done with the update.
I hope someone can get that because it holds the key to the answers we are looking for.
Who knows maybe one of the developers will read this thread and be able to help.

try a battery pull and obviously reboot. Download the Gsam battery monitor from the market. I think it is free. It dumbs down a lot of stuff and pretty much tells you what is taking up your battery. It does a much better job than the stock battery checker. After an hour or so, the longer the better, it will show you some apps or processes that are the culprit.
Battery stats app is a paid app in the market but I think it is free on this xda site somewhere for members. That appears to be a very comprehensive battery monitoring apps with wakelocks and it gets very complicated for a novice such as myself.

can you provide additional details on your situation, for example:
what's your baseline comparison, e.g., before: 18 hrs use with 4 hours screen time, after 13 hours use 4 hours screen time
are you rooted (i suspect not)?
have you gone into Settings->Battery to see which apps, etc., are using your battery?
do you have a lot of music, pictures, etc on your phone?
not an answer to your question, but... have you considered performing a hard reset on your device and then testing battery life with at clean slate?
looking at your battery stats is a better indicator of what could be causing poor battery life. i'm on the same release as you and my battery life has been the same if not better. also download better battery stats to see if you have wake-lock issues. i'm averaging 16-20 hours per charge with 6-9 hours screen time, about 150 emails daily and 35-90 minutes in phone calls.

So yesterday at 19 hours of use (maybe 2 hours total of emails, web surfing, and using a couple apps, music for an hour at the gym) I still had 32% left. Not bad. However, my wifi was off all day, even at home, and I kept my location services turned off. So tomorrow I am going to test it with Wifi on at home and my location services and see what happens. The Gsam battery app i used yesterday was pretty cool although at first I wasn't sure because it said that the app was using 15%. But as the day progressed it never went over 4%. Still new to the android platform, but learning.

I APPRECIATE the response however I would like to know what was done with the 4.1.2 upgrade, what changed, enhanced or whatever as well as the AT&T maint just prior to the 4.1.2 upgrade. Nothing was disabled, I was runn8ng the same exact software load, same apps, no games, and wifi wS constantly on. While disabling bloatware, shutting down this and that, turning off wifi at this point is helpful, its not a acceptable answer as to what happened.
This forum has some of the most respected developers and computer genius's around. Whenever you ask for something and everyone else comes up empty, the first thing you hear is go to XDA.
My Galaxy Note2 had the most incredible battery time of any device I've ever owned prior to the updates. Im also pissed because I didnt even know that the red and grey arrows and the connecting to dnr server was AT&T doing a update. There was no forewarning.
The Note2 is still fabulous to me, I just want to understand what has happened and why. I am not asking for a say in what they did, certainly this is my phone, I believe that I should be entitled at least to know what transpired.
There should be no problem producing a comprehensive change log with a lay person level explanation.

I was getting 2 days off charger with 8 hours of screen time and suddenly the battery doesn't seem to charge past 50% and I didn't do a single thing to it but tonight I am cleaning everything out and starting fresh because something odd is going on

I think the key to many answers is 2 items.....a log and explanation of what occurred in simple terms regarding the 2 updates. There was a no warning automatic att update done just prior to and then the actual 4.1.2 update itself. My gut opinion is something was changed with wifi and how its handled along with some other software changes.
I feel like. Dog chasing my own tail...disable this, disable that...bull...nothing was disabled and wifi was always on prior the updates.

Battery Issue? Phone turning off for no reason...

Hey I have been noticing a weird issue with my phone.
Ive flashed a few different ROMS to see if it was a specific one or if it is something else. Yes, that didnt work.
I am still having random turn offs which shut the phone down. Whether on it or not it happens at least twice a day.
Does this have something to do with the battery? When i reboot the phone the battery level shows at what it was...
last example I had was 68%. So it wasnt fully dead. I was going to send my phone back but decided to stick it out and maybe a new
battery will work? Any help will be greatly appreciated.

Take your battery out and place it on a flat surface. Try to spin it. If it spins, it's time to replace it.

Try a stock rom for a few days if the battery seems fine. My phone has the sleep of death issue with various jellybean AOSP based Roms.

One thing I've noticed. My Battery will get extremely hot. I'll pull the battery, wait for 5 min, put the Battery back in and will be able to proceeded.
Just my $.02 worth

It's certainly the battery, only fix is to replace it.

Happens to me once every other day. Not a big problem just take out the battery and replace it back in.
I'm about to change the rom temporarily from goodness to blu kuban to see if it continues.
If it does then it has to be a battery issue at least on my end...

Time for a new battery.

Battery issue with Galaxy SII
The shutdown issue seems to be inherent in many SII regardless of carrier. I have had this problem with my Sprint phone since new. It has been exchanged twice thus far but the problem continues. Samsung will tell you to do a factory reset. DONTdo it. It will not fix the problem.
It is NOT the battery in most cases.
It seems to be OS related. I have cleaned the battery contacts; not charged unless below 20%; unchecked the Power Saver and Optimization functions; and did a factory reset without loading in any additional apps for awhile. Nothing stopped it from shutting down.
I was able to prevent shutdown for about a two week period by not charging it until it went below 20%.
I did notice that my RAM consumption was over 60% prior to the phone acting up.
Could it be a memory issue?
Thus far, I have not received any real support from Samsung or Sprint. The Galaxy SII is one of the few phones that cannot be run through a diagnostc test by Sprint. If you have warranty coverage, they will replace it but I can almost guarantee the problem will beda plague to the new one.
If anyone has found a solution to this shutdown thing, I would love to know it. Right now, I check my phone status very often throughout the day to see whether it is one or not.

What rom/build are you on? Rooted?
Your problem isn't a common topic here unless your running experimental nightlys or doing a bad flash/install or your battery is no good.
I have two Epics since 10/2011 and have never encountered this condition. We did replace the batteries on both phones in 12/12 because of rapid discharges, going from 90% to 50% after a reboot or running a system heavy app like browser, camera, or YouTube.
Other than that all we do is use and charge when necessary.
Both phones are rooted, her phone is a workhorse because of her job, fashion design NYC, keeping track of 4 email accounts (2 gmail, 2 Microsoft Eexchange) plus crazy messaging all day long.
Check your phone model.
It may be different. Maybe you have the wrong battery in your phone?
There where some instances that had some Epic's with 1500 mha batteries instead of 1800mha!

Phone is not rooted....straight OS. I will check the battery to ascertain if it is a 1500 or 1800.
Phone is an SPHD710. It's only three months old and has been swapped twice by Sprint. I think it may be ICS. When I got it, they updated it to the latest OS which was ICS fron Gingerbread, so I don't know if it would have had the same problem with GB.
I'll try to get a new battery from them and see if it makes any difference.
Thanks.

Sounds like the power button might be going bad. If you are not getting sudden large drops or increases in battery % I would lean towards the power button.

I'm having the same sort of issues on my S2. I've had it for about 6-7 months and it's worked fine but the last few weeks it's been almost unusable. Within 5-10 minutes of using my phone it will shut off, regardless of the battery level. Turning it back on would show that it was critically low on battery and it would shut off again within seconds. Plugging it into a charger would let me turn on again and restore the battery level to what it was, oftentimes over 60%.
It seems that the false battery reports come and go, but the real problem is that the phone just keeps turning off. It's useless without a charger anymore. I've looked on Sprint's forums and it seems like many people have been having the same problem. Especially after the new JB update. I've been running stock so I figured I might try a custom rom. I rooted and went back to FF18 but I can't load up a custom recovery to install a ROM. The link to download the autoroot package in this thread is dead.

I have run into the same issue starting about three weeks ago. I am already on my second battery, which is only six months old, but it was behaving as if it was dying again, so I got another brand new one from the sprint store just to make sure... Phone was still shutting off though. After some more research, I came across someone who had a bad card reader in their phone. They even wrote a program that keeps track of mounts, ejects, and bad ejects. I downloaded it (its called sd card monitor), and sure enough, my card is ejecting itself multiple times an hour (which is no surprise, this phone has destroyed several cards already)... If I remove the card, I have no more problems... So for now, I am using my phone without a sd card. I am not paying Sprint $50 for a refurbished replacement at this point, I am fed up with their service and will be changing carriers after the S4 comes out...
The strange thing though, the sd card issue doesn't affect the phone if it's plugged in.

Can you confirm that your phone is having the same issues due to the card reader.?
If so please share.
(Otherwise you need a new battery.)

I ran that SD card monitor app for about 4 hours and no disconnects, so I guess it's a battery issue.

[Q] Worth upgrading to NF4? What's new?

I currently have NB4.
What's new in NF4? I know it has the VoLTE but that's not in my area so nothing for me(yet).
Are there any improvements?
I guess what I'm trying to ask is. What are the pros and con's of upgrading from NB4 to NF4?
I also run w03 slimkat. Is it compatible? It shows its compatible with 4.4 BL. Just not sure if that's updated to include NF4 BL.
thanks and sorry for being a noob.

I have no idea as to what exactly is "new" in NF4 but take it from me,
if there wasn't any improvements then why would Samsung waste their
time, money and effort with the NF4 or any other future updates?
There are no "cons" to upgrading NF4 or any future official updates.

Of course there can be cons. Thats a laughable statement. Until it's reported the update is fine, you can have broken root, locked down bootloader (not as likely on T-Mobile) a bad build that causes bad battery drain. You must be new to the phone rooting and roming world to say "There are no "cons" to upgrading NF4 or any future official updates"

I don't want any fights started. Please keep it casual.
With that being said. Yes there can be some pros and con's.
Like I said before I know that it includes VoLTE. That's the main feature. However That is not available in my area.
What I would like to know. Is there better internet connectivity? How's battery life. My biggest problem with T-Mobile in my area is it keeps dropping from H+ to 3G. 3G and below are like being in airplane mode. I end up having to disconnect and reconnect to get H+ back. Does NF4 fix this? If not Is there any tricks/mods to help with this issue. Or is it just ****ty network in my area?
and again I will continue to use W03 SlimKat. currently running V23 waiting on V25.
I'm looking for people who have personally updated there phone to NF4 and can give me details on how well its running.
Thanks

For me, battery performance increased noticeably and it seems like connectivity is better. At my house it used to always switch from 4glte to 4g and since the update it holds the lte connection better. Sunday morning there was a quake in the bay area and since then data has been weird. ..but up to that things where just buzzing along. I came from NB4 and like i said i noticed worthy improvements.
***BTW i did a full wipe in recovery, powered down, pulled battery, booted into download mode and odin'd the full firmware file, everything except External SD.

Thanks, Based on this information I have decided to go ahead and update to NF4. Running W03 SlimKat V24 sofar so good. Once Google gets done restoring my apps I will turn off WiFi and update this thread with my findings.

I know many people claim better battery life after updating to 4.4, but I don't see it. I just updated about a week ago from 4.3 (MI7) to 4.4 (NF4) and battery life is similar at best, but mostly worse.Not only that, but charging also takes much longer. Normally my battery would fully charge in about 2.5 hours, but couple nights ago it took 5 hours to go from 10% to 82%. I went back to sleep and finally was fully charged after additional 3 hours, but then as soon as I turn it on, went down to 97%. I never seen that before. I run 0228 code and discharged to 0 and then back to 100%, so hopefully that will calibrate battery better, but still just last night phone was at 100% before sleep and in the morning down to 80%. Normally on 4.3 I would loose 3% to 4% overnight. I just hope it's temporary and will improve after settling down, otherwise i will need to run some serious diagnostics and fix it. Antutu also seem slower, last time I run it on 4.3 I got 37083, under 4.4 I barely got 35000.

Not my experience at all. Battery drops maybe 2-3% overnight. Stays at 100% longer than it had and charges plenty fast from 1% to 100% way under 5 hrs, but i never really timed it yet i can say it was under 3 hrs and i remember being surprised at how quickly it got to 80' something percent. Every month or so I run my phone down to 1% just to help the battery cause I'm usually on a charger and rarely get below 50%. Maybe a good wiping might tune things up for you.

I believe you, you're not the first person claiming better battery. I don't want to wipe, too much headache to restore and settings and games in progress, also my kids are on my account, so either no automatic reinstall (BTW how do I stop it), or a lot of deleting kiddie games, already went with this process once before, not fun. Probably something simple, since I'm stock rooted and always been on my Note3.

yup, its a coin toss.....once I saw the stability that comes with full wiping I can't not do it, stopped me from being a flashaholic. Titanium Backup can backup/restore your apps but settings/shortcuts/widgets etc have to all be set back up....I take screen shots of all my home screens to aid the process of getting back to normalcy....gotta weigh the pros and cons

it shows battery info, also there is a button on bottom, if pressed it changes battery charge level, so it was speculated it does some quick recalibration, but as with all other codes no one knows for sure. Sure this is in some secret code lists, but i don't think there is a list that have them all, otherwise they wouldn't be secret anymore. LOL
There were few threads about this code in past, but i don't remember where now.

Well sofar everything is great. Network still gets stuck in 3G and I have to airplane mode to get H+ again. However it seems like its not doing this as often.
Better life is the same which is good because battery life was awesome before the update.
I will update if anything changes.

That is exactly why I froze my updater and stayed on jb4.3.
Now that KK has been out for a while and should have bugs fixed, what are the pros for updating from jb to kk?

I didn't update for long time mostly because of SD card issues, which could be fixed, but needed root, but again, root would trip knox. Now that we can root without breaking knox, I finally updated. Personally didn't see much: people claimed better battery, for me is little worse, many claimed faster snappier response, I don't see that either, on the other hand, so far haven't seen any SD card issues neither, so didn't even need the fix yet. One advantage, I already made my first VOLTE, so it works and it's on in my area and you need KitKat for that.
Add to this probably few security fixes and some tweaks under the hood and probably that's it. IMO, the update did not fix any issues for me, except wifi calling that broke recently, but I didn't have any other issues as well, but at the same time the update didn't break anything major either, so it's pretty much wash, unless you need VOLTE.
Note 4 comes out in few weeks, so that was my backup plan in case update was messed up, but as it is Note4 needs to win my heart on it's own merits.

Physical battery question - trying to trouble shoot issue!

So basically I am running eragon 6.7 (dirty flash from 6.6~, was a clean install before that) and I have just started to have an issue which I am trying to trouble shoot!
So I upgraded my phone to this version AND dropped it on concrete on the same day so unsure as to what one caused the issue...... but basically since these events my phone won't charge over a certain point (on 3 different chargers/plugs/USB ports). Initially it wouldn't go over 42% and then I wiped the cache and squeezed the battery shield and magically (or coincidentally) it started to charge up to 92% but no higher. With normal use today I went from 92% down to 15 in under 9 hours!!!!!!
Looking at my battery stats it is showing as fine, normal voltage and no issues.
ALSO when browsing the web I noticed that the top of the phone (above the battery, by the camera and top metal edge/screen gets REALLY hot - this doesn't seem to happen when I have bluetooth, music, GPS and maps all open at once though.
So my symptoms are slow charge that won't go to 100%, QUICK depletion, HOT phone when browsing the web/screen on (above the battery) but my battery stats read all OK. Could the battery be at fault here still or is it likely to be another piece of HW damaged in the fall or could it be a flash/eragon related issue (doubt it).
I have stripped the phone down and removed the battery and can see that the bottom edge/underside of the battery's wrapper is 'crinkled' and malleable to the touch (but this may just be the wrapper), also the battery's bottom ~1cm is everso slightly curved upwards. Can anyone confirm if this is normal please? and if the battery wrapper is normally 'skin tight' against it or is some movement along the bottom edge normal?
I would really appreciate any help as I am currently sitting with a dismantled phone in-case I get any suggestions!
Thanks and apologies for the lengthy first post.

I would bet that it's certainly the fall that has caused these issues as the ROM has not changed that much, you can always go back to older ROM if you want to know for sure! I have not opened my phone yet so can't answer your other questions but perhaps someone else might be able to confirm this for you soon. Good luck!

Thanks for the reply, that's what I am thinking!
Update - I upgraded (dirty flash) to eragon 7 and issue still persists, I don't know if it's worth ordering/waiting for a battery only to find that it's another component that's gone or to just scrap it and get a new phone (oneplus 2 most probably)

Well, for the price and with the Eragon ROM the p8000 is very good value. The oneplus2 is a lot more expensive so you would hope that it's worth the extra money

true! I think I may need to bite the bullet and get a new p8000

Update
So I upgraded to Eragon 7.0 and now the phone is charging to 100% but still draining very quickly!
Strange.... could this be linked to the Rom afterall?

Can you flash a stock Rom and see how that goes?

That was going to be my next try but before I did that I done a backup with Titanium, full wipe, clean install of 7.0 and a restore and I think this may have actually resolved my issue!!!!! the phone is currently saying 68% with 13 hours approx left!

Nice! Wonder what is going on with your phone?!

God knows! I'm just glad it seems to be resolved now... although the phone is still getting hot towords the top when doing anything like browsing/navigation etc.

Help, extreme draining

Hi, i bought one moto z play, almost 2 months ago, and the battery was excellent, you can see on airplane mode, idle, not using it, the phone lates more than 17 days, and had 23% of juice left, after that, i boight another one, both are used, but this one, only last 2 days on the same conditions, airplane mode, even safe mode, not using at all, just 2 days, drains like 2% per hour without even touching it at all, what can i do?

What does it matter what happens when you never use it? And why buy a second phone if you already have one that lasts great?
Just sell the second and start using it like normal people. Nobody can tell you why that difference is and it doesn't matter. They have to last under normal conditions, but what you are doing is pretty much waste of battery. Letting it lie around in airplane mode for days is simply stupid. Then you could just turn it off

Seems like a reasonable test of baseline battery drain to me. I get less than 2% drain per hour with all my background stuff on with my MZP. My old S6 (notorious for bad battery) gets like 3% per day in airplane mode with no screen on time.
Just because his use case isn't your use case, doesn't mean what he's doing is stupid.
OP, I'd be inclined to think you have a hardware issue - you've eliminated all the normal software side stuff that typically is responsible for battery drain.

Exactly, it was just a test, obviusly under normal conditions the drain Is Worst, only 3 SoT and 9 hours of battery, if you compare the two phones, one drains 2% and the other 0.1% por hour, that it's not normal.

If is not hw issue, something is draining battery in background. Have you tried factory reset? Compare settings on both phones, wifi/bt scan, SIM is inside on both, sd card?
Anyway, try to make both phones exactly the same from hw and sw perspective. If you haven't already.

Maybe put a CPU monitor app on both phones, let them both run in the same condition for the same time period, and see if the histories match? Not really sure how else to look, since you said safe mode didn't fix it.

the one with the problem has the december patch update, the good one, the november patch, thats the only difference on both. already tried factory reset, wipe cache, safe mode, even on safe mode, the 2% per hour draining persist.

gonna FDR both, charge them to 100% and let them dry for a couple of hours with the cpu monitor.

You can try to upgrade good one to December patch to get the same batter life result
If there's no other difference, then looks like that is hw problem. But I'm still suspecting that you are missing something.

good joke, but im not gonna take that risk; cant think what i would be missing; i think ive tried everything except for a downgrade, but i read somewhere it cannot be done, the phone is on 7.1.1.

Do not downgrade. It is doable but next upgrade (OTA) and you will end up with brick.
I've already asked you, both phones are with/without SIM/sd card?

both phones on airplane mode, without simcard, without sd card.

Well, if both phones are the same from hw and sw perspective (except update on "bad one") then most probably cause is hw or update.
Do not try to downgrade, 8.0 is under SOAK (quite long already, but still has issues) and you may try it when is ready (don't flash leaked SOAK, please).
As said above, most likely is hw issue. Sorry for that.

camera app left running?
