Excessive Battery Drain - Samsung Galaxy Note FE Questions & Answers

Hi, I've been using my Note FE (SM-N935F) for more than 6 weeks since I've bought it. The battery life is horrible. Drains like water.. I've attached couple screenshot in order to ease your identification..
PS: I've not been using this device much because I was worried about the battery drain and not having much left at the end of the day but I've lost 10 percent in just 15 mins of writing this thread on XDA

Nexus 4 Battery Life

Hey Guys,
A bunch of people are complaining about the battery life on Nexus 4. I've been waited for a couple days since I got the device, to have enough confident about the battery before I make any post here. Yes, the phone battery drain pretty fast on the first few cycles. After a bunch more charges later, let me tell this, the battery life did get significantly better. It lasted about 10-15 hr depends on the load of the usage.
Here is my typical day, off the charge at 100% in the morning, listen to a few songs, checking emails, and messages while getting ready for school. About an 30mn to 1hr of internet browser and youtube videos while on the bus. By 1-2pm the battery drop the about 70-80%. I put the phone in silent mood til i'm done with all my classes. On the way back home on the bus, I listened to a bunch of music, web browsing, maybe a few phone calls, texts or games.
Compare to my old phone, Samsung Galaxy S2 T989, im impressed with the Nexus 4 battery life. My Galaxy S2 battery always die on the bus coming back home. What I'm trying to get at: if you're a light to medium user like me, then get this phone. I was hesitate at first because I always have bad experience with android battery life. But Google seem to get its OS right with this nexus device, mainly because the battery drain minimum while in sleeping mood.
Can you post your Nexus 4 battery performance screenshot if you have been using the phone for more than a few days ?
Is there supposed to be a question being asked? Or a statement as this is in the Q&A forum.
I agree with you on many points. People need to wait at least 5 to 7 days for the battery charge to fully kick in. The first days mean absolutely nothing as it is still being aligned plus the user is still installing apps and setting up their phone.
There are some notable problems in the default kernel that uses more battery Usage than normal too.

From full battery to this overnight + breakfast usage. Rasbean + Matr1x v3.0. Never seen anything like it. Coming from the GN, this phone is a different dimension altogether. On any aspect..
Had phone for 5 days. Drained phone to 10% then fully charged. Moderate to light use made it through a day.
Stock rooted + Franco Kernel.

Depends on how much screen time you got, which you didn't show us.
The trick is to be careful about using mobile data when signal is bad, I switch to WiFi when home to avoid unnecessary battery drain.

What is this obsession for battery life, it lasts me well through the day with moderate/heavy use. I charge it at night (if needed) and unless you are homeleless this shouldn`t be a problem. It`s a great phone and i enjoy using it.

I thought the same until my N4 actually arrived, it seems battery life is abysmal compared to my Optimus 2x which didnt have anything really spectacular in regards to battery size. On my O2x I could get 1.5 - 2.5 days depending on use, hitting atleast 1 .5 which was good and acceptable for me (I can charge at night anyways) however my N4 doesnt even reach 13 hours on similar usage!.
I am quite a light users of smartphones however I do like to have a power phone when it comes to using it on the basis of smoothness and capabilities if I need to say do work on my phone, I rarely play games though. Main usage is 2 email accounts on poll 1 hour steps, a third account that is an exchange server and polls in 30 minute steps and thats about it with some brief browsing and a handful of texts (been a quite time since I got my N4), this is less usage than my O2x and yet it still performs alot worse!
I was hoping of staying with stock as I was expecting it to finally be good, comparing it to LG stock attempts it is but battery life isnt . I will be trying the combo Vangelis13 mentioned, raspbean and matr1x kernel as that seems like a great mix however Parandroid has been on the table and it seems like alot of being are getting good results so I will try it soon .
If I can get more than a day of usage I would be really happy, if I was playing games or doing really heavy tasks I wouldnt expect it to last but right now it is doing pretty much nothing and dieing far to fast!.
One thing I've noticed since coming to N4 from S2 is that phone calls drain battery much more significantly on the N4. I could make an hour long call on my S2 and it would use no more than a couple of percent battery but the N4 used 15% for an hour long phone call the other night.
If I didn't own a nexus 4 and came to this thread to find out about it's battery life I would expect it to be good.
Point is you guys are misinforming everyone. The battery is mediocre and that's it.
It won't last a full day if you use it constantly and I do need two charges / day many times.
Let me put it this way, you will only get roughly 3 hours of screen time on stock everything. If that is good for you then it's will have good battery life, if not then you will say it's got poor battery life.

you are perfectly right.
I come from an iPhone 4s, which I changed because the battery life wasn´t that great and I thought it was time to try something new.
Got the N4 last friday and played around with it during the weekend.
Monday, tuesday and wednesday this week... none of these days I´ve been able to come back home with the phone still on.
I wake up at 7.30am and I usually am back home at 6pm.
In my opinion, and honestly should be in everyone´s opinion, 10 hours of battery life are unacceptable, whatever the usage is (considering that 7.30 of those 10 hours I was at work)
I have till friday this week to return it, which is a pity because the phone is great
i get 5-6 hours sot..
rom is omnirom 5.1.1 hellscore kernel b73.
100mv undervoltage hellsactive governer.
think 7 would be possible if google services would not take a quarter of the battery.
the screen is not taking that much battery as one would think.
think most issues with battery life come from fake original battery replacements.
had 3-4 sot using "original" battery. but after replacing with real genuine from official lg spare parts shop 5-6...

[Q] battery life question

I just got the octacore version yesterday, and the battery life is not very good. I basically had to charge it 2 times in 1 day with just normal usage, and on wifi. Does anybody know if the battery life will get better over time? Lets say in 1 weeks time? Because I feel like I have a faulty one, and that I can return it in 30 days.

Battery will not be anywhere near it's optimum potential until you have fully drained and recharged the battery at least 4-5 times.

It should get better daily.
My first charge cycle was barely 8 hours.
Then it went to 10
Now I am up to 17 hours.
Also remember you play with a new phone more... its bound to run down fast because part of it is your getting to know the device by playing with it alot learning feeling it out.
My typical screen on is 4 to 5 hours

Battery life

I know this isn't new, but I am about to give up on this phone. Battery life is terrible (24 hours at most). I have tried all the suggestions I have found in this forum, but nothing makes much difference. Is ANYONE getting more than 24 hours??
Im getting less than that with about moderate to heavy use,most of it on lte,just over 5 hours screen on time

I must be doing something wrong. I usually get 8-10 total hours, maxing out at 2.5 hours of screen on.

Enough to let me go out of the house.....
When I first got mine it lasted about 2.5 days but rls8 and 9 of hyper drive combined with a certain game I don't get a full day.
I believe I have identified the source of MY excessive battery drain. It is Safestrap, specifically the use of more than one ROM slot. Yesterday, preparing the phone for sale, I deleted the two extra ROM slots I was using. Battery drain went down about 50% overnight (using stock slot(ONLY)).
How long have you had your phone? I've had mine for a little over a year, and the battery life on it has began to slowly degrade no matter what I do. I've always plugged my phone in at 20% or less, and if I could help it wouldn't leave it plugged in once charged completely.
Also, Before you go to sleep - Try clearing RAM and recent apps. I know it sounds silly, but it's helped my overnight drain quite abit.
You can only use stock rom slot or you will get very fast battery drain. With alliance build one I had 7 hours on screen time. AZ biker has a great thread in general section he easily has gotten 8 to 10 hours on screen time. Good luck.

Are you sure? S4's battery is 2600 mAh. It should take about 15 hours or more to make the battery become low with minutes of gaming.. I have S3 mini and its battery is 1500 mAh and it takes about 12 hours or more to make the battery become low.
I can get 5 hours on 60 percent but I gotta be using battery saver with data off when I lock the acreen
take a look at this:

Gaming or watching movies will discharge your battery in a few hours. 4,5 or 6 hours max. Depending on what you're doing and other stuff like wifi and screen brightness.

Was the battery life always terrible or is it just now?
I'm having a similar problem so I'll use this thread instead of creating a new one. I hope you don't mind.
My battery is draining at a rate of 15% per hour even If I leave it on standby, ocasionally turning on the screen to get a message on Whatsapp of checking the time. It was 100% this morning, 1 and a half hours later, 74%.
After reading on the forums that the cause of the battery drain could be that the phone was constantly trying to get network signal (in cases where the signal is poor, like where I live), I decided to switch on airplane mode. To my surprise, in 3 minutes after this the phone was in 75%. 10 minutes later and I got a 76%. As I write (on PC) it is on 80%.
That's right. The phone started "recharging" without a cable (I know this is impossible, just describing what the display shows me) after I turned on airplane mode.
Any ideas about what might be going on and how can I solve this?
Thanks in advance!
P.S.: It's not the battery itself, as I've bought a brand-new, samsung original battery and the draining was still the same
EDIT: the battery started behaving like this only a few weeks ago. So I'd assume that the signal problem could be helping, but would not be the main reason on why my battery goes down so quickly.

Not tried the airplane mode, but i'm sure that if i put to charge it charge quickly, too quickly.... like it was 80% 5 min after 90%

You could try that and see if it is a rom problem.
Otherwise try to borrow a battery from somewhere just to be sure it isn't the battery.

Battery life

What kind of battery life are you guys getting?
I was getting really bad battery life, barely getting 4 hours screen on time(100-2%). Well now that I've had the phone for a week, it seems to have settled. Today I'm going to break the 7 screen on time barrier(100-2%)! I think this is great! This is with auto brightness set around 40% I think. I dont understand the auto brightness.
This battery life thing was KILLING me. I was ready to return the phone if it didn't improve. Well the battery has settled and the improvement is almost doubled!! Once I hit 2% I'll screen shot and post!
Here's the pics!
I have to say this. Even without root or an unlocked bootloader. I'm pretty satisfied with this device. The last android I used was an S5 and this little guy is like it, on steroids! Out of any androids I've had the S5 was the only phone I kept for longer then 6 months. I had it for 14 months. I hope to do the same with this phone. Though with a locked bootloader. I dont know if that will happen. I think if this device was unlocked and undervolted. We could get another hour of screen on time out of her atleast. We'd atleast figure out wth is going on with Android systems and put a stop to it!
Any one care to comment?
I love it so far using my s7 since February 29.

Yea, over 100 packages disabled. I have also gone through a warranty replacement. Some others suggested debloating could hurt battery so I even tried adding it all back but recently removed it all again.
Is anyone who is getting great battery life using a gear s2? Only thing I can think of
I am not getting much over 4 hrs screen time.
I was getting 4 hours as well. I dunno. Im consistently getting 6 hours atleast. Well... My phone better then yours ?
At first i was getting 5 hours sot, I debloated and a week later it's constantly at 6:30 SOT. Used package disabler pro from app store, the made debloat packages thats on the app. Great phone by the way. I gave up the note4 and don't regret for a second. I still have the note and every time I pick it up put right back down and immediately go back to s7
The new update seems to have helped with the android system destroying the battery. Normal when I get home from work im at 61-65% I'm at 73% right now with 2 hours 22 minutes screen on time
No improvement here I don't think. 4 hours off the charger, 20 min calls and 20 min SOT, 88%. Android system and OS are lower but still high
Your usage really matters here. I have a buddy who got this phone same say and he is about to hit 2 full days with 5:30 screen on time. Which I think it's pretty dam good. Phone sleeps well. My usage is different and I get 5:30 hours but only 1 full dy (24 hrs) consistent

I'm seeing better than expected battery life, averaging between 4 to 6 hours SOT. I will say this, what's odd is it goes from 100 to say 85 percent pretty quick and then it's a slow drain. I haven't even got it down below 10 percent yet.

Interesting observation, I get to 85% really quickly (i.e., in 30 minutes SOT).
