Battery life gone down the drain after firmware upgrade

Hi guys,
A couple of weeks ago, Note II informed me of an upgrade. I did a bit of googling and found out it was to fix some exonys bug. Seemed pretty important so I did the upgrade post haste.
At first the battery life was atrocious (like a 50% drop). The same thing happened with my old iPhone 4 but everything reverted to normal within a week. So, I though maybe things are new and Android will fix itself up after some time.
How wrong was I ? LOL. My phone gives me just a day's worth of battery life. Earlier it was a solid two days. Which was why I justified carrying this brick of a phone. It is pretty ridiculous to see the battery drop by 30% at times in three or four hours (despite zero use).
Any suggestions to improve or remove the pathetic firmware upgrade.
1. Use the nova launcer
2. Auto brightness with the slider dragged to 1/3rd
3. 3G always on
4. The battery screen shows screen taking 70% of the battery! I have the auto off timer set to 15s the minimum.
Any suggestions guys? I am frustrated with this phone post the update. Thinking of switching back to the iPhone as atleast it gave me a day's pf juice in a much pocketable format.:crying:

I am a very simple user, I did not install any applications (just transferred some music and installed Super Hexagon)after the firmware upgrade.
Could a firmware upgrade cause this much drastic drop in battery life?

There is a known battery drain issue with 4.1.2. What firmware did you update too?

Yes, but that battery drain issue was only in the first 4.1.2 release, the latest one does not have this issue.

Yes, I got the 4.1.2 upgrade which has played havoc with the battery life.
But the drop has been extreme in my case.

Honestly you can't do anything. In American english, you can't do nothing!
Turn 3G off, when you don't need it. Keep brightness at as low as possible.
That's all. 4.1.2 drains juice faster than 4.1.1, it's the truth, doesn't really matter if someone agrees or not.
You could go back to 4.1.1 ROM you know and depend on your luck for that Exynos issue. Otherwise give up on great battery backup and stay with 4.1.2, like I'm doing. Nowadays I don't even monitor how much battery backup/screen on time I'm getting, on 4.1.1 it was the opposite story however.

Hey, so should I just resign myself to a gimped battery? What really hurts is how awesome the battery was before.
Any word on when samsung would release a good update?
Sent from my GT-N7100 using xda app-developers app

Download better battery stats to make sure there is no wake lock. I will advise despite my best efforts the battery life has plummeted when upgrading to 4.1.2. Stick to 4.1.1 for battery life. It still lasts much longer than an average handset saying that

After updating to 4.1.2 my battery runs down about 20% quicker overall I would say. 70% for your screen seems severe. Mine is always set to 50% auto and takes between 30 to 35% of the battery usage.

If you go back to 4.1.1.... Stock even....you'll have the same battery issue.

After about 2 weeks of having the 4.1.2 (the second update I received) on DBT my battery life one day just magically got better! I had been having terrible battery life (like 1 days worth) for 3 months, and now I get home every day from work with 50-70% battery. I charge it every night, regardless of the %. But it just magically got better. I'd say give it a go for a week or 2, and see if it helps. I don't know what happened with mine, but it looks like the software just "settled in" because I didn't install ANYTHING new, and in fact, I hadn't even uninstalled anything! It just got better after using it. Do a few battery pulls / restarts, too.

I went back to 4.1.2 last night and right now I'm at 50% charge, 17 hours standby time and 5 hours of screen time... I'd say my battery issue is fixed.. for now lol

I also must say that after a week or so of using 4.1.2 battery went much better overnight. I automatically turn on airplane mode during night, and on 4.1.1 I had like 1-2% drain overnight from full charge. After updrage to 4.1.2 it jumped to 10-20% !!! Now, it is down to like 4%, which is not that bad. Still have to see how it behaves during the day, I think it is not any better. Well, at least that standby drain is (much) better....

I decided to dirty flash 4.1.2 and it worked great for me. We'll see how it goes after a week or so of use though
A thanks is always appreciated if I helped you.
Edit: After 50% battery drain in 8 hours of light/moderate use on wifi I'm going back to 4.1.1... I see no benefit of using 4.1.2.... The reason I bought my note 2 was to have a battery that will last me all day and this isn't cutting it.
Thank you MobileOdin for making this easy!!!

This is windows os right? Things not going fine, reinstall from scratch,!

I had intense heat in phone during my early purchase this month. Later after OTA update, the heat was completely gone. Today, all of a sudden heat started again and battery drains in 30 minutes, yes 30 minutes. Nothing new installed. Any reason?

I have same issue
my note 3 is very fast in discharging
when i have fully charged in 100% after a few minutes nothing touched it goes 99% then on keep browsing it goes 98% with an extra heat also..
this is only happen if you are on the stock kernel
i think the stock kernel for note 3 must be adjusted for battery saving...like note 2

Turn off animations. Dim the brightness . That solved both battery and overheat and lag issues for mr.
Sent from Note 3 (The beauty & beast)

I just noticed that brightness is already set to auto and it's less than 50%. Let me further reduce it
By the way where is animation option?
So bad to do all these to make battery survive. Samsung should have thought these well ahead before pushing so quick on new products.

Exhange Services is any email account and calendar sync other than Gmail&Google Calendar. To turn it off, get rid of those. Not ideal. Putting them all on manual sync does the trick too.
As for the spontaneous heat, sounds like IndexingService.

I never had this problem earlier after recent update. Started heating up from yesterday only. Putting my corporate email to manual defeats my purpose. What's the indexing thing you mentioned?
I try calling Samsung support and they insisted to bring all kits by Monday. Will keep it posted here.

Same here! This is the second day I'm using Note 3 and this didn't happen on Note II.
Now I disabled all Dropbox syncs, and disabled ALL sensors movements and just let enabled the s pen commands. Reduced the brightness to the minimum also. But it's still hot, even after rebooting.
I will disconnect charger and go out and see if, like yesterday, the battery will drain. Oh! And, by the way, I didn't charged it when I went to sleep and when I woke up I noticed that from 3AM to 8AM my battery dropped from about 40 to 7 and then stopped going down, but when I started using it battery drain started so fast again until it turned off.
Now I just made a full charge with the device turned off and let's check what will happen today with this new settings...

Kitkat killed battery life

Kitkat killed battery life. Used to be great, now it sucks.
Sent from my SM-P600 using XDA Premium HD app

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.

I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time

Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.

I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.

4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.

I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.

You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.

Factory reset and see if it still happens. A dirty flash can do weird stuff...

[Q] N9005XXUFNF4 - why is my battery drain is worse?

This phone is becoming a joke, it seems that with every update Google or Samsung are crippling this phone.
N9005XXUFNF4 was supposed to improve battery life on the Note 3, so why is my battery drain worse?
I bought the Note 3 to do away with netbooks and tablets, but now I am being forced to use them again.
When I use the internet, browsing on the Note 3 itself, my battery can lose 50% in under 30 minutes. I am then forced to switch off data out of fear that the phone will not last the day.
However, when I tether a notebook or a tablet to the Note 3, it will give me about 8 hours of internet usage before it needs charging.
So what is the point of the Note 3 now? It is quickly becoming just an expensive modem.

Are u using fully stock ? Root it, delete bloat apps and install a custom kernel. I just did these and hardcore debloated now I'm getting perfect battery/performance.

And this is why I am happily sticking to NB7 for the forseeable future.
-6%, 1.30h screen-on time, wifi on, tapatalk, firefox and gmail.... (at -60% brightness though(lux).) No root, full stock.
If it isn't broken, don't fix it.
Tried a full factory reset yet?

it is all because you need to do a full wipe my friend.
I guess after update, you haven't do a full wipe. NF4 comes with new bootloader, and though a same KK, but different base version from NE or any older one. A full wipe from stock recovery will make it better.
But don't forget, backup your internal sd card first, as any factory reset from stock recovery will do a full wiping on your internal SD. All will be gone. ...
Stock firmware has never given me that type of worst battery usage. especially in 30 minutes ? wow....
FYI, I always like to do a clean install, especially jump up firmware.

this is also my new problem when I update. before update, for one day, I charge to the maximum of 4 hours (not continuosly) full battery. today, my percentage of charging is 12 hours. this is crazy. I think I might root my phone now in order to solve this problem.

Note 2 owner willing to upgrade to Edge

Hello everyone .
I am currently a Note 2 owner and I skipped upgrading to note 3 as it did not seem such a big upgrade to me plus all the goods <software> was brought to me by the devs of the Eteam . Was willing to upgrade to Note 4 but then Edge came along and now thinking of getting one of these frontier devices.
The problem that I see from the forum is the battery life in this device , I can consider myself a power user and I do get in average of 4 to 5 hours of screen time on the 2 year old Note 2, anyone coming from Note 2 can shed some light regarding this issue as I am so used to have more than just 4 hours of screen time and that is a compromise I am not willing to make since I consider this am upgrade , is Edge worth or better get a Note 4 ?
Thank you in advance.

Here's the thing, note edge/note 4 has double the screen resolution as your note 2, and the edge has a battery 100mah less than the n2. Granted the processor can give you plenty of standby time, but screen on time won't be as good as you currently have it. You can always carry a spare battery, since it's a Samsung.

I had the Note 2 and it was not exactly a stellar performer in SOT from what I recall. You won't notice much difference going to the Note4 or Edge in that regard. Maybe a slight improvement. But the screen quality and performance will more than make up for it. Plus the new fast-charging capabilities are pretty effective.

You can't compare the note 2 and note 4 or Edge as apples to apples. The processor alone on the Note 4 is more efficient. And if you get the T-Mobile variant you'll get root and can do greater control of things that eat battery.
But even the stock versions allow you to at least disable most of the bloat or apps you won't use thereby stretching the battery life out.
I have both the note 4 and note edge and get at least a full day on them. I consider myself an average user doing primarily email, music, web and some gaming (temple run 2 is my addiction) and I get at least 4 hours of screen time with about 25-30% battery left by the time I go to bed.

I picked up the Edge after having a Note 2 from release. I see a massive battery life difference for the better. I had replaced the battery in my Note 2 twice, and in it's prime with Ditto Note flashed, I was pulling almost a full day if not a full day of heavy use. Since picking up the note, I've been getting home from work with atleast 30% left. Actually, I don't think I've had a low battery notification since I picked it up. Looking forward to rooting, but out of the box...I'm impressed Samsung.

OMG N2 to N-edge
YOU WILL LOVE IT, I cant put it down. The phone drinks battery but purchased 2 extra batteries with portable charger. When you buy the phone samsung gives you 50% off all accessories. Well worth it, I loved the N2 and the N3 wasn't enough to upgrade off contract. N-Edge AWESOME:laugh::laugh::laugh::silly::silly::silly::victory::victory::victory:

And as an added bonus, the edge has 'adaptive charging' which allows you to go from 0%-50% in 30 minutes. That combined with 'quick charge 2.0' and swappable batteries, you should be good to go.

This was SOT of my Note 2 when battery was new.
More than 9 hours on one charge.
When I hear you guys telling that I need to carry a spare battery with me or that the supercharger does 50 % in 30 min , I simply get scared.
Of course I will root and debloat the device but .............
Still sitting on a fence about getting this awesome device or not.
Thank you all for the feedback.

Maybe someone will come out with an extended battery that will last all day? At least I hope they do.

Same situation. Same comments. I'm on the att varient. I heavily modified my note 2 and frankly I'm OK with no root for now. Very happy with my upgrade.

I switch from a Note II to the Note Edge a few days ago and I love it! The only thing I'm missing is root... Ordered the spare battery charging kit just like with the Note II using the 50% off coupon. do iT!

I'm in the same boat.... but want an exynos version. ...

You'll receive a 50% off coupon code once you register your device with Samsung. It's a one-time use only... Hope that helps!

My Note 3 has about 15% better battery stats than my Note 2. The Note 4 from what I can tell is about the same as my 3 but that's with the higher res screen. My guess is that the Edge will be about the same as the 2, at least that's what I'm expecting anyway.
Now only those with an edge could attest to this but if you use your edge screen wisely to skip all the full screen on 10 sec checks of whatever wouldn't that save bat in the long run. If you can quickly edge through your notification without turning the whole thing on that should save you lots by the end of the day.
