Just sharing my experience..

On NIE firmware i have been streaming milk to my bluetooth speaker at work.. all day every day for the past couple weeks. And i can get 2 full days of usuage before i have to charge.

Like today.. i started the day off with 52% battery from this morning. Still streaming and im at 15%. I got about 6 hours left in my day, getting ready to go home soon so streaming will stop. It will be close.. hell i might just charge it for 5 min to make it the last hour. Love the fast charge capability.

Moderate usuage for me.. screen is off most of the time except when i need to reply to txt or phone calls. Or when i check xda, or browse the net.

We have the crappiest signal here too inside this metal building on the 2nd of 3 levels, interior office.

Let's get this going again now that lollipop has been out for a while.
[AT&T Samsung Galaxy Note 4] NYYFan02:
Battery has definitely taken a hit since lollipop, probably getting max 4 hours screen time, was getting close to 6 on kit Kat.
[AT&T Samsung Galaxy Note 4] diablo900t:
My battery life has been terrible ever since I've owned this phone, now worse with Lollipop and I'm seriously considering going back to an iPhone at this point. Done multiple factory resets, disabled every single feature I can think of, turn off location services, turn off bluetooth and I'm lucky if I get 14 hours on a single charge with moderate use (2 hours screen time, 2 hours talk time maybe with 1 hour of listening to bluetooth audio). Now its been shutting off completely once I reach 10% or so. I have 3 batteries with this phone, and they all get awful battery life. Recently I've been having to charge the phone midday just to get through the rest of it.

Here's what my battery life looks like for the past 6 hours. Drained from about 92% to 45%. 1 hour 17 min of screen time, and about an hour and a half of bluetooth music on Google Play.

I had incredible battery life on 4.4.4 but now on lollipop it is crappy. 3-4 hours SOT the most out of 2 day use. I used to get 5 days easily with 5 hour SOT.
[AT&T Samsung Galaxy Note 4] falcons2:
I miss the days of being able to get 5 of SOT. Now I'm lucky if I can get 3. :mad::mad::mad:
[AT&T Samsung Galaxy Note 4] borijess:
Yes ever since LP battery has been terrible.
[AT&T Samsung Galaxy Note 4] Dr. Evo:
I am finally happy with Lollipop, but sadly, it had to be at the expense of starting all over again.

Up until last week, I was rocking the original Note 4 I bought shortly after launch. I was a great device until I updated to Lollipop. Instantly, my phone went from the best ever, to a large paper weight. I could have a fully charged battery, listen to one song on my media player, and easily drop 3-4% in battery. Most times, I could literally stare at my screen and see the battery percentage dropping like it was nothing. I tried all of the tips and did everything I could to avoid a fresh install that would wipe all my data. Nothing worked.

Then, my microUSB port quit working out of nowhere. Samsung quality, huh?? So, I had no choice but to get a warranty replacement. My new (used) phone came on Thursday. I spent an entire day debating on whether or not I'd be foolish enough to screw around with Lollipop again, or stick to Kit Kat which gave me incredible screen-on time. Eventually, I couldn't resist the Lollipop Material Design that I was really missing. I took a huge chance and updated to 5.0, since my phone was pretty much factory reset with only a few dozen apps installed. It's been a whole weekend, and I can say I'm now reliving my Kit Kat glory days! Battery feel one percentage point in two hours of being idle. I got thirteen hours of moderate usage the other day, with 20% battery still remaining, but I can't quote screen-on time. I'm just happy I could go a full day without recharging. On my old device, I would have to constantly keep my phone connected to a charger, or it could be completely dead in about 3-4 hours!

So, maybe a fresh Lollipop install is key for most people, even though it doesn't work for all. Good luck to anyone still suffering out there. I understand the pain!
[AT&T Samsung Galaxy Note 4] isri:
Hello,

With kitkat it was quite well, 2 days wasn't big challenge to achieve.

After upgrading to lollipop it's got worse, normally I'm able to get it working for about 15 hours. But today it's got crazy, check the screens :(

I'm using ROM from official, Polish distribution.

from 100% to 10%, 22 hours used (screen on time 3 hours)

i dont think the battery life is so impressive, but it's surely not bad.
[AT&T Samsung Galaxy Note 4] cmdbr03:
With 15% left i am at 5h20min sot, never once on wifi all on 4g lte, 2 hrs alone was netflix streaming on 4glte and about 40mins in facebook. Also 2 hours of voice calls. On cricket.
[AT&T Samsung Galaxy Note 4] glenroebuck:
My battery life is horrible - I have been testing over three days - I do a full charge to 100% of a Nexus 6 with MM, My old Note 3 wiht 5.0.1 and my Note 4 - All three screen brightness set to 50 % wifi on no GSM/LTE...

Today is 20 hours after I started - (I also did a full reset on all the phones - then re-entered just my google info) - of the three right now

Nexus 6 - 89% battery left

Note 3 - 94% battery left

Note 4 - 68% battery left.

WTF?? I keep hearing and reading how the note 4 has amazing battery life and I was never seeing it. Could I need a new battery?
[AT&T Samsung Galaxy Note 4] xphyle1971:
Same here. No, a new battery will make no difference (i've tried that). Greenify doesn't help. A factory reset won't help. The problem started and was caused with the update to 5.1.1. I'm lucky to get 3 hours of SOT on a daily basis with every battery saving measure I can think of. It's ridiculous. The only hope is that the marshmallow update fixes whatever problem was introduced with the 5.1.1 update. But by the time AT&T gets around to releasing it, I'll have moved on to another handset.
[AT&T Samsung Galaxy Note 4] diablo900t:
How are you guys getting so much screen time? I'm lucky if i break 3 hours. Android System is consistently hogging up 30-40% of my battery. I have no idea what is causing it, I've even been running Battery Doctor and killing background apps all the time and I've turned off sync on almost all of my mail accounts.

Any suggestions?
[AT&T Samsung Galaxy Note 4] swatty43:
Here are my battery stats, I am pleasantly surprised on the battery life on the phone so far:
[AT&T Samsung Galaxy Note 4] JasonJoel:
I got over 6 hours screen time yesterday. Am at 1:40 screen time today and still at 80%. So I'm pretty happy.

No power saving modes turned on, auto brightness, no WiFi.
[AT&T Samsung Galaxy Note 4] silentecho13:
I don't even know how you guys achieve so much screen time. I get 2-3 hours at the most and all I really do is browse forums, text, or use Chrome.
[AT&T Samsung Galaxy Note 4] JasonJoel:
I would say you either have a defective phone, really low signal strength causing the radio to be max power all the time, or a very nasty app sucking your power down...

[AT&T Samsung Galaxy Note 4] diablo900t:
I think my issues might be poor signal in my apartment. Hovering at 1 bar most of the time. I guess I could run in airplane mode and see how it goes.
[AT&T Samsung Galaxy Note 4] ekinnee:
No WiFi?
[AT&T Samsung Galaxy Note 4] diablo900t:
I have WiFi on. Here's some shots of my current usage.
[AT&T Samsung Galaxy Note 4] ekinnee:
I bet it's the fact that you show a half hour of voice calls in the bad reception area you live in. That'll suck battery fast.
[AT&T Samsung Galaxy Note 4] diablo900t:
You're probably right. This is what my mobile signal looks like.
[AT&T Samsung Galaxy Note 4] Jennygirl:
I had awful battery life the first few days. I was right there with the people getting 2-3hrs.

Then I disabled unnecessary sync services (I think a big one was photo sync), gestures, s voice (I use google now), turned off all bloat apps, and now I'm getting ~6 hours screen time.. as long as I don't use navigation on google maps or Waze. Those drain it like nothing else.
[AT&T Samsung Galaxy Note 4] NYYFan02:
This thing is killer, destroys any phone I've ever used as far as battery goes. This is with my normal everyday use, about 10 hours of that is in airplane mode from work.
[AT&T Samsung Galaxy Note 4] ekinnee:
10 Hours in Airplane Mode is not something to brag about. What good is the device with no data connection?
[AT&T Samsung Galaxy Note 4] NYYFan02:
Even minus airplane mode it's over 1 day of battery (with data, Google now, sync , etc) and 5.5 hours of screen time; way better than my old S3.
[AT&T Samsung Galaxy Note 4] XavierD8188:
Yeah I did the same thing and I am more than pleased with the battery life. First thing I did before even signing into my phone was to Disable all the AT&T bloat and tweak the settings, turned off motion gestures then I logged into my google account and disabled all sync services for things I didn't use. Also Apps like FB, Twitter and IG I turned off the notifications and sync for them. Also Auto brightness is great as well. Performance seems smoother when you turn off all the motion gestures too
[AT&T Samsung Galaxy Note 4] Euphoria64:
I have been on the fence about whether to get a Note 4 or not. Seeing the terrible battery life, I think I know my answer now. There were some getting 6+ hours of SoT, which is very good in my opinion.
[AT&T Samsung Galaxy Note 4] XavierD8188:
Battery Life

Light to heavy usage. On mobile network for most of the day and only on wifi when I'm home from work. 1 1/2 day on battery, 5 hours of on screen time. Brightness set to Auto, turned off all gestures, only sync stuff I use, disabled all AT&T/Samsung bloat and also turn off s voice.
[AT&T Samsung Galaxy Note 4] b3asty:
I admittedly have not measured my battery life yet from 100 to zero so I don't have any super impressive shots to post. However, I will share my experience with hopes that perhaps it helps someone. I like my background services but I do go in and disable unnecessary sync items when first setting up any device. I want "relevant" background traffic.

So I typically work in an area that has poor AT&T service to my radios for every droid I have owned. Thry have always been busy during my work day trying to acquire a good signal so battery drain is a major problem. I have had every single Note that has come out. This one was no different. So I went looking for a solution. I looked high and low and found some roads that led to a particular app. After taking a leap of faith and installing it, I am happy to advise that my radio loves me. On day one (monday) after 4 hours of work, I went to lunch with a battery percentage that had dropped from 100 to 74 in just 4 hours.

Since installing the app which disables the radio while the screen is off and turns it on at 5 minute intervals to allow background data, in that same 4 hour span, I drop from 100 to 97 percent. It's really amazing... the app is called Auto Data and it is available at the following link. Don't contact me if your phone blows up. I'm just reporting my experience. ?

https://play.google.com/store/apps/details?id=auto.data

I'm a VERY happy camper right now. Getting in the car after a day of work and still having 93 plus battery left is freaking ridiculous.

One other note, the Note 4 radio is definitely an improvement over the equivalent radio on the Note 3. Same spot at work. With my N3 I was barely even receiving a signal at all so correspondence via mail or IM was basically non existent. With the N4 I am usually able to hold a bar which allows that type of comm. Slight improvement but enough to make me very happy.
[AT&T Samsung Galaxy Note 4] Jennygirl:
Sign me up for the happy camper club

Anyone getting bad battery life, check your sync services. Also GPS seems to kill it faster than anything. If you do any navigation you can watch the percentage go down every minute at times.

Overall though I'm super impressed. There is no going back once you get this device working well. It definitely does take some finagling the settings.

Never give up hope!
[AT&T Samsung Galaxy Note 4] Hardcore73:
I got 8 hours on screen time yesterday with phone being on for 16 hours. Mostly Twitter, facebook, Flipboard, and about 3 hours of Netflix. Very happy with battery results. WiFi was on most of the day and 6 hours Bluetooth to my Moto 360.

I also love the quick charging on my phone.
[AT&T Samsung Galaxy Note 4] diablo900t:
I'm still getting poor battery life. Max I get is 3 hours screen time. What does the CPU time on android system look like for those of you with good battery life?

[AT&T Samsung Galaxy Note 4] diablo900t:
So jealous of you all with good battery life. Mine has been getting worse, I have yet to reach 3 hours of screen time on any given charge. Right now I'm at 81% with only 22 min of screen time. I've disabled everything i can think of, including location and bluetooth - even removing my microSD card because I read of an issue with Android System and an external microSD. The only account I have set to Push is Gmail, and all of the other sync services beyond calendar and mail are turned off.

I'm not sure what to do at this point :eek:
[AT&T Samsung Galaxy Note 4] done12many2:
Reset and wipe the phone. Something you're not seeing is running and running strong! Once you've wiped the phone, install apps as needed and watch battery performance in between. Should you see a spike in drain, you should be able to limit the scope of your search to the last few setting changes made or apps installed.

Are you using power saving mode?

Also, I think you should take it back if you can't get better than 3 hours
[AT&T Samsung Galaxy Note 4] diablo900t:
I've tried with and without power saving mode, doesn't seem to impact the battery life at all.

---------- Post added at 02:27 PM ---------- Previous post was at 02:25 PM ----------

I'm going to try doing a wipe over the weekend.
[AT&T Samsung Galaxy Note 4] tampaboy1984:
No complaints here. My Note 2 would've been dead already.
[AT&T Samsung Galaxy Note 4] ekinnee:
It looks to me like most people with poor battery in their details screen show to have crappy reception. This will drain batteries quickly.
[AT&T Samsung Galaxy Note 4] diablo900t:
I'm hoping that's what my issue is. I did a factory reset on the phone and ONLY added my Gmail account and no other apps and it was still draining fast. Android System is always around 20-30% of the battery, and if i'm lucky i'll reach 3 hours of screen time.

When is AT&T going to release the firmware update??
[AT&T Samsung Galaxy Note 4] xlr8shun:
not the best reception where I am located during the day (At work) stupid metal buildings...

but, like any other normal day, emails like crazy, milk playing constantly, and little bit of this and that throughout the day.

below represents about... 2hrs of screen time also
[AT&T Samsung Galaxy Note 4] diablo900t:
I just got a microcell to improve the poor coverage in my apartment, but my battery drain issues are persisting.

Is anyone else using battery doctor? Even at a full 100% charge, the estimate shows 20-21 hours of battery life, I'm just curious if anyone else has it installed if it says the same thing or I've got a bad battery.
[AT&T Samsung Galaxy Note 4] Ghstudent:
Absolutely no complaints here. Those 4 and a half hours weren't light usage. I was at a party using Snapchat, tweeting, Facebook, I used the navigation for 30 minutes or so, and then Netflix for an hour and a half this morning. I don't know what the hell Sammy has going on under the hood of this beast, but it works. This is only my 2nd day with the device, so the battery might not be all the broken in yet!
[AT&T Samsung Galaxy Note 4] jordant2:
Great battery life for me. I have been cheating with power saver on but I don't have the reduced brightness enabled, I love my brightness too much! I have it set to auto brightness always. Mostly web surfing/xda, a half hour of Google maps, and some Google music.
[AT&T Samsung Galaxy Note 4] tampaboy1984:

Thanks, I think people should put any changes they made.. In my other post there, I said I put my brightness at 20-25%.. that's usually good for indoor office type (but probably auto or near max when you are outside).. Also, I had three emails (two hotmails, one exchange) and set all of them to 1 hour.. with these two changes, the battery went up quite a bit.. in that other posting (a few pages back), I went down to 95% battery and got 45 minutes OST out of it..
[AT&T Samsung Galaxy Note 4] cxyjordan:
Guys, right now I am on 3 days 16 hours and 2 hour screen on time I still got 40% left. It's amazing.
[AT&T Samsung Galaxy Note 4] XavierD8188:
New personal best. No mods or tweaks. 6hrs 19mins of on screen time. Was never on wifi, all LTE network and still had 5% left. That's boss. Lasted 1 day 10hrs. Only thing I've done is:

1. Disable Unnecessary Sync Service

2. Turn off motion Gestures

3. Turn off S voice

4. Disable AT&T and Samsung Bloat

5. Leave auto brightness on

6. In Power Saving Menu uncheck ‘Limit Processor’
[AT&T Samsung Galaxy Note 4] harlenm:
No idea why my battery lost 26% overnight with no use. Otherwise it had been pretty good lately.
[AT&T Samsung Galaxy Note 4] XavierD8188:
If this is a screenshot of usage overnight then something is constantly waking your phone up. If you take a look at the 'Awake' portion of your stats, you can see something was waking your phone up very frequently through the night. At best I'd lose only 2% overnight. Do you have anything syncing in the background like gmail, Facebook, Twitter or any other social media?
[AT&T Samsung Galaxy Note 4] harlenm:
I usually lose about .5% per hour overnight. No idea why it was 4% per hour last night. Nothing changed in my setup.
[AT&T Samsung Galaxy Note 4] XavierD8188:
That's really weird. Can you post a screenshot of the main Battery stat page that shows what's using your battery ex: Screen 20% Android System 20% etc.
[AT&T Samsung Galaxy Note 4] harlenm:
It wouldn't matter, I've been using it all morning and am down to 42%
[AT&T Samsung Galaxy Note 4] XavierD8188:
That's def not normal. I can go about a day and a half with 6 hours of screen on time easily. You may need to factory reset your phone to fix whatever issue is causing your battery to drain so much.
[AT&T Samsung Galaxy Note 4] diablo900t:
I wish I knew how you guys are getting such good battery life. I've done 2 factory resets and it's still poor. Android system and OS take up 30-40% any given charge. Only my Gmail account is synched. It was poor with nothing but stock apps installed.

Max screen time is around 3 1/2 hours. I'm at 3 hours of screen time right now with 24% battery left.
[AT&T Samsung Galaxy Note 4] XavierD8188:
This is the only thing I've done:

1. Disable Unnecessary Sync Service

2. Turn off motion Gestures

This is now typical of overnight, no idea what happened the other night.
[AT&T Samsung Galaxy Note 4] nyydynasty:
i typically get about 15-17 hours with about 2-3 hours screen-on time but I also stream music for about 2 hours a day so that also plays a factor. I'm happy with my battery life, though. I was hoping to get a full day but this is fine, especially since it charges really fast. And now that I got the fast charger for my car, a 10 minute drive can charge the phone about an additional 15 - 20%...which is amazing. It's also worth mentioning that I leave GPS, BT and WiFi turned on all day. I dont use battery saving mode and I dont turn off anything to save battery. Its really nice being able to do that now ... with all my previous devices, I had to turn off some things just to get 12+ hours.
[AT&T Samsung Galaxy Note 4] diablo900t:
Ran for a day with power saver on. It's the same if not worse. Android system is always the top drain around 20-30% no matter what I do.
[AT&T Samsung Galaxy Note 4] XavierD8188:
It's possible you might have a faulty device. Why don't you take it back to AT&T or BestBuy (wherever you got it from) and have them replace it? You're still under warranty considering the device is slightly over a month old.
[AT&T Samsung Galaxy Note 4] dlgreg:
I also had terrible battery life with the Android system always the biggest drain.

After trying to configure the phone to save battery I finally gave up and took it to an ATT service center.

They reflashed the firmware; ATT had to do the procedure twice as the first time the flash failed.

I had to re-install all my apps and re configure the phone after the re-flash but couldn't be happier.

The battery life after the ATT re-flash is excellent.
