Battery life with 3G Always ON, Not connected to WiFi

Hi guys,
I'm interested in purchasing Galaxy note 3. I'm an iPhone user, but I've used Android until Nexus 4. I really want to switch back because I love customizing my home screen, but I'm really afraid at the same time. The reason is that with every single Android device I had, the battery life on 3G was horrendous. Even in standby in 3G, the battery drains super quickly, and when using, it's even worse of course. It was always hard to get it last through the day with only 3G and no WiFi connection. Signal I believe was okay too, not extremely good, but also not terrible.
Could you please (with no bias) let me know what the battery life with 3G is like on this device? Hopefully with Lollipop because that's the only reason I'm switching to Android. I don't like all the android versions before Lollipop.
Thanks so much!

Hello, i use a Note 3 (SM-N900) lollipop and im always on 3G. I get max 7 to 8 hours on 3G! But it depends how you really use the phone. Im not using power saving mode. Hope it helped you.

Hello, thanks for replying!
7-8 hours screen on time, or the phone just lasts 7-8 hours in total? If it's the latter, that's pretty short, similar to my past Android experiences.
You said depends on how I use it, but how do you use your Note 3? Are you a very heavy user?
I'm a moderate user. I need it to not run out of battery for at least 15 hours, with maybe about 5 hours screen on time. Again, on 3G. Is this possible? I don't play games. Just browsing the web, quite a few mobile data messaging, etc.

If you use the battery saving mode, it is better... but V5.0 drains battery a lot more than 4.4.
You say you don't like previous versions to 5.0... but I don't think you have tried them and they look almost the same (you can even install a launcher that makes it look exactly the same). Newer isn't always better -- at least not until a few updates lol.
Picking a phone with large battery is always good if you want longer hours.
But if you're an iP... I can't even it say it, it makes me sick lol... perhaps also look at the Sony phones. They have amazing battery life and a lot simpler in function like an ippp -- you know.

I can't answer about the 'always on 3G' because I use AutomateIt to switch between Data and Wifi. But you can get an extended battery that should give you much more time on - the zerolemon one is about 3X the mA/hr rating of the standard and there are others that simply replace the back on your phone so you can have a thicker battery.
But much can be done also by setting up the phone correctly - remove bloatware, check for settings that drain power, or even using something like AutomateIt to turn data off when the screen shuts off would help. Greenify is another app that can save a lot of power - it hibernates apps rather than let them keep running when you aren't using them.

Hello!
I understand where you are coming from. I have a Note 3 (Stock lollipop with root) and I am always on 3G because I travel quite often and barely bother to swtich to WiFi even when I am home. On the stock rom, I usually get about 4-hrs of screen time depending on what I am doing.
If I am downloading a lot of stuff and if I have too many apps that need updating, then the screen time drops considerably (Say 3 and a half hours). But with regular use (whatsapp, 4 email accounts all syncing, auto-updating via 3g turned on) I have never had any problems getting through the day.
Also, I have the Unified Daemon disabled. I have heard that this really chews through battery. It is used for updating weather and all, and it is not really needed. Also, on LTE however, battery drains much faster (even on standby). It has a standby life of maybe 15hrs.
If you really want great battery life, I agree with @cyberboob, they have outstanding battery life. My Xperia Z ultra lasts 3 days and then some under mild to moderate use and a week under light use. I have seen Xpera Z3 show similar resilience and they are fantastic phones to boot, not to mention waterproof. (Till you have used a waterproof phone while bathing, or near a (or in a) pool, you will never know what you are missing. Once you go water proof, you cannot simply go back!)
Hope this helps!

Thanks guys for your help! I will hold off for now and maybe look into Xperia Z3 or Z3 compact. these devices are more expensive because they are newer so i need to think about it more. again, thanks!

LOL - don't take this wrong, but you should probably stay with the Jobs program. Android works best for the Classical types. Apple is better for the Romantics. (read 'Zen & the Art of Motorcycle Maintenance' for definitions) Long story short... you want your solutions given to you. Android users (most of them) are willing to do a bit of work to make things betterer.
It is sad for the human race that Apple keeps selling so many crippled devices... le sigh...

Well..ive had android from 2009 to 2014 and i have tons of experience flashing roms and fiddling around. But the thing is, i could never get though the day with 3G. I tried so many things i could think of but even on standby one of my phones as example drained 4 percent per 30 minutes. Probably some apps i installed but i needed all the apps. Greenify didnt help though. I tried Anker extended battery that has 400mah more with no thickness change (for T989) but still no difference. Didnt want to try crazy big batteries cause that would make the phone way too thick. Iphone has similar battery life when screen is ON But standby is much longer. I'm a light to moderate user at work so i can actually get through the day with this phone. But then again i really miss home screen customization and lollipop's flashy design looks so cool so i was looking into android again.

I get about 5-7h screen-on time on stock with 75% brightness, no root. Disabled most bloatware. GPS & sync off. (depending on the app, 9GAG drains more than Moon+ reader, for instance.) More if I use a lower brightness.
If I watch a film (720p mkv) it lasts about 6 hours.
In deep sleep it drains about 1% per 8 hours on 4G. (3G uses even less).
Mind you, I'm on 4.4.2, and an older version at that. (feb 2014). On AMOLED black uses no battery, and Lollipop is all white. And people wonder why Lollipop drains faster?
Here's screenies of my best use. (I was reading a book, black background with grey letters.) :

Well it seems like you have the experience to be able to use a Note. Sorry if I seemed harsh. Most Note 3 users seem fine on battery, although most also use WiFi as well as data.
Mostly it's a matter of setting up, tuning to your setup & letting it settle in. 5 hours SOT is probably a minimum but it's rare for me to get to end of day with less than 30% left.

Note 5 Battery Life

So far Day 3 of using the device on a normal workday. (It is officially released in Singapore on 15 August 2015)
Seems pretty well optimised!
No powersaving mode, normal use at the end of a typical workday, some calls, WhatsApp, text messages, games, etc.
Using the Scroll Capture btw.

Thanks for all the screen shots - it's sad that it's only gonna be 3-4hrs of sot. My note 2on stock battery and Cm12.1 gets 6-7 sot.....
Hopefully the note 5 gets better than your initial findings.....

Adidasfreak's numbers translate to about 4 hours SOT before dead... For me that is bare minimum acceptable, as I really like to keep my phone >25% in case I need the reserve.
I'll have to wait and see others results. 4 hours SOT isn't anything to brag about though.

Well here's mine. Much better

Even when you post battery data people still just ignore it. 50% remaining after 10 hours (3:45 SOT), averages of 17.5 hrs with 8.5 hours of SOT) is damn good by any measure.
I don't get all this negativity. OK. Maybe the SD card is real but you can't really dispute that it seems that battery life isn't something to complain about. For a group of technically adept users, I find this amazing. I swear reading all these posts is like reading transcribed rants of spoiled teenagers...

Phone Arena just did a comprehensive benchmark test on the Note 5s battery. Apparently, it really does outperform the Note 4. But by how much in real world usage, that's still debatable. At any rate I am a lot less worried about battery life on the Note 5. And, I got to play with the gold S6 Edge + and the beautiful titanium gray Note 5, today. Not as wowed as I thought I would be regarding feel, but they do look beautiful.

Yeah, I saw his results and was a bit underwhelmed

I think the only way I'll be able to decide is to just pick one up and eat the $35 return fee if it isn't good enough.

This is always my approach. I look at it like a "Try It Before You Buy It" fee that's refunded if you keep it.
Last year I actually added a third line to see if I really wanted to go back to Apple (had an S4) then cancelled the third line within the 14-day window once I convinced myself I wanted it...
...of course that was a failed notion since this POS has been slowly driving me mad ever since. Yes Mr. Jobs, I ONLY want to snooze for 9 minutes. Yes Mr. Jobs, of course I would NEVER want a keyboard that changes case to match what I'm typing. Mr. Jobs! Of course I wouldn't want to have free access to all that memory you graciously allowed me to buy at rediuculous prices as if it was a USB stick... :cyclops:

I really wish battery life was so obvious to compare, but it isnt. We are too smart here to fall for this. Battery life is extremely personal and nearly impossible to compare. "Normal day" usage... that's just funny. The best you can do is to compare consistent benchmark data.

Why don't you use a power bank in case the battery is getting low? The Note 5 battery life is not the best among others, but based on the benchmarks and users' reports, it is acceptable and not terrible.

I've never had a better battery. I hope it stays like this

Getting about the same since Monday evening. It charges freaking fast tho

The Note 5 battery is *brand new* vs almost a year old on the Note 4. Until that is considered, these comparisons are bullsh*t.

I already saw a comparison of a 1 month old Note4 vs a brand new Note5 and it was pretty much the same story.
Unless a 1 month old battery is going to be VASTLY worse than a brand new battery.
Also the Note5 SHOULD use less power than the Note4, they moved from 20nm SoC to 14nm, moved from LPDDR3 to LPDDR4 which runs at lower voltage (and faster), and the new display which is 18-23% brighter while using 20% less power.
So it really is no surprise the Note5 is getting better battery life with a smaller battery.

What about the fact that the Note 4 is running an older version of TouchWiz and an older version if Android as well? Was that considered?

Of course, but since they dont have identical builds we can't really compare it at the moment. But even on the newer OS I really doubt there is anything they can do about the inferior hardware of the Note4. The newer tech in the note5 just uses less power, hence the smaller battery with similar or better battery life than the Note4.

lol why bother trolling with ridiculous hypotheticals? Maybe we should pull out a Note 1 and demand a current version of TouchWiz and Android to make it a device lifespan comparison? Newer devices are built to accommodate advances in hardware as well as software so it's idiotic to demand comparisons like you're proposing. The reality is that once a new device is released the older ones lose priority for software updates and optimizations and you're rarely, if ever, going to get a true apples to apples comparison.

What's wrong with my note 4 ?

Hi everyone,
I have a Note 4 (SM-N910F) running android 5.1.1 (build LMY47X.N910FXXU1COH4) for about 1 year and a half now and i'm so surprised of how the performance have decreased, plus i have some weird things happening every now and then such as :

Having no internet connection, but i'm on wi-fi. This doesn't come from the network i'm using because it happens even when i'm connected to a different one.
My battery life is really ****ty... Plus when i'm around 30%, my phone shuts down and when i turn it back on again, i'm like at 1%.
I'm not root.
I really don't know what to do. Is there any information i can give you that will give you tips on things i'm maybe doing wrong causing my phone to have weird behavior ?
The thing i want to know is if flashing a new rom was a good idea, and maybe if you have advices to give me on roms.. I'd like to be as up to date as possible, and a light rom. Doesn't care about touchwiz feature. I just want my phone to be reactive, fast, and working normally.
Thanks for your answers.

Change your battery. Some posters claim to have lag when their battery are nearly dying as well.

Do you update regularly (Apps & OTA update)?
Try to turn off WiFi & then turn it on again.
As for battery....it's degraded to only 70% of its full capacity.
Usually when it reaches around 40% your phone will stutter + lagging heavily, so make sure to charge at around 50% if you are still considering to use that "broken" battery.
My Advice is to buy a new OEM battery or any good 3rd party battery.

It is a little similar with my 2014 Note 10.1. It also shuts down on its own at right arount 33%. But only sometimes. And yes, it also stutters. I can not vouch for other branded devices. But, I have heard similar stories from friends on their Samsung devices. Definitely get a new battery. Like another post staited. OEM is a great choice. Or, at least a very reputable 3rd party. I purchased a battery for my Note 10. And even though it was new, it was not the same. I found that the circuitry in the cheap aftermarket battery was sub par. The seller sent me a free replacement battery. And it also had issues. So, make sure you get a reputable battery.

Batteries aren't linear though. Its voltage drops off in a curve. (e.g. 4.2v = 100%, 4.1v = 90% and 3.7v = 20%)

Same problem on my 10 months old Note 4 N910C. And it was started about 2-3 months ago, so the battery lasted about 6 months!? Also, there's a burned-in damage on my screen (notification bar)! Yes, warranty is still valid, but anyway... NEVER AGAIN Samsung phone!

Hm... You right about signal. I never looked at this, because whenever I use the phone (at home) and I'm always on 4G internet (unlimited plan), signal meter is on 1-2 bars.I don't know why is signal so bad, when phone is off. Power saving is always ON. About wake locks... I believe that they are from my smart watch (bluetooth),but Bluetooth version on Note4 should be low-power (connection is lost when I'm 4 meters away (in my department)), so... This days I can't reach 2h of SOT (4h-5h when it was new).

Interesting. I'm curious about the power saving if that actually reduces your signal by keeping it in a lower power state. I have never used power saving mode and my rom doesn't recommend it. I wonder if running in normal mode would effect it.
Might look at what apps are using the bulk of your battery as well to see if something rogue is running.

Before Note my phone was Sony Xperia Z and power saving on that phone did a great job.That's why I still use this feature. I also put many apps into the "optimizing mode"... There's no any special app which uses battery. There was Facebook, but I uninstall it.Battery monitoring apps are useless for me because phone is not rooted (still under warranty). Maybe I should try hard reset.

I know it's old thread, but anyway... Last week I finally take my phone to the service, because it's still under warranty. They changed the screen because it was burned-in, they changed the battery (sudden power-offs) and strangely - they changed some faulty system connector. Phone worked and charge befor the repair. I always use only original charger, so how can be some system connector burned??? They changed it for free under warranty, so I assume that it must be some factory fault. I know few people with the same "sudden power-off" problem on different Samsung phones, so...

New firmware update USA model

What's new:
Improved camera UI
That's it. No other improvements. The update is 150mb in size, so i am hoping there would be behind the scenes bug fixing. Especially hoping it would fix the wifi sleep battery drain issue. Will update this thread in a couple of days on my findings.

Update: I can confirm that this update does not fix the wifi/sleep issue. Went to bed at 10pm and checked the tablet at 6am. Lost 12% battery. Battery Usage tells me the tablet was awake the whole time and did not go to sleep mode. This is really bad compared to my S8+ which only loses 3% battery overnight.
Still the fix would be to switch off wifi before going to bed and the tablet will only lose 1 to 2% of its battery.

This one lost 5% over sleep but that's still a lot. I'm testing an old Asus Nexus 7 for the hell of it (it hadn't been turned on for 4 years and literally two days ago updated it to 5.1 and just left it to see if the battery would hold). The Nexus 7 is beating the S3 so far. Also have an iPad to compare and that thing can stay in standby for a month solid.
I'm just going to turn it off when not in use, waiting a minute for bootup (plus fingerprint so no having to fiddle with pw screen) isn't a huge deal to me.

Yeah it's annoying that Samsung can't get it right, even after more than a year with several devices running on the SD820 platform. I just don't get how my pixel, with nearly the same hardware, is so much smoother and more battery efficient. /rant
Anyways, I just have WiFi set to turn off when the screen is off. I only charge it once every 4-5 days with light to moderate usage

Idiots are probably not aware of the issue. WTF is there no theme store?? Getting tired of this SAMMY BS.

Download LInk?
Does anyone have a link so I can Download the latest update? Or do I need to remove root and then update in the traditional way? (I would prefer to have a file I can flash in Odin)
your help is appreciated.

FYI - I have a case I keep my tablet in. WHile in the case, I didn't use the tablet for two weeks. Busy having fun with new S8+) anyway, I still have over 50% of my battery remaining. When I open the case, the screen comes on very quickly. It appears that being in the case has helped to put this thing to sleep and I guess that puts battery drain down to about that 2% to 3% your S8+ gets.

Does anyone have a link so I can Download the latest update? Or do I need to remove root and then update in the traditional way? (I would prefer to have a file I can flash in Odin)
your help is appreciated.

Remove root and go back to stock if you want ota update.
You should be able to find the firmware on sammobile.com.
I also have a case on mine with the screen on off function but still the tablet doesn't go to sleep.

Sammobile doesnt have the firmware for XAR which I beleive is the US. I saw a link previously for the old firmware somewhere to samsung firmware - but when I search that site, I can't find the new update. I will try other options.
thanks

Everyone seems to be using the tablet for light duty thus far.
I'm going to chime in and add that I'll be using it for CPU intensive apps. Re: SoundCamp, FL Studio, and other heavy tasks. Don't think this will live up to "12 hour run time" that everyone's oohing and awwing over XD
I wound up getting the battery to about 13% and turned on "battery saver" for the day. It was supposed to last 23 hours. When the work day was over (about 16 hours by the time I got home) it was off. Figured it was worth testing time to complete-off from full charge. No idea when it actually turned off, but the system isn't optimized for this so-called battery saver mode either. Every other device I've owned with this feature has had accurate results (sometimes more), but not here.

Thinking of returning mine coz of the wifi bug and going back to my s2.

What kind of bug? Lost connection? I have this issue on mine s3
Enviado do meu ONEPLUS A3003 através de Tapatalk

The battery drain bug thats been referred to in many places here. Not sure if and when it will be fixed.
The older S2 doesn't have this problem and it seems like the Exynos 5433 with it's 8 standard ARM cores as opposed to Qualcomm's custom 4 cores in 820 (though theoretically faster) handle Touchwiz better with less UI jankiness since both run Nougat 7.0 now.

There is a a ADQC firmware out for a lot of countries including UK, trying that one to see if the Wifi bug is fixed. Why do they delay the US version so much is beyond me? Same story with the S2 firmwares, went to the Germany/Singapore version since US receives firmware updates last, even though there are no carrier delays for the Wifi only versions.

This firmware resolves the issue: http://updato.com/firmware-archive-select-model?record=1D0F4E90377111E7963AFA163EE8F90B ! Confirmed 0% drain over 3 hours on standby would have def lost at least 2-3 % by now.
Look for BTU firmware T820XXU1AQDC if the link expires.

Does anyone not charge their tab overnight? That negates all of this *****ing. Then it is at 100% when you wake up. Win win for all.

I charge on the weekends. I use the tab to take notes for work during the week.
Currently, I have tasker turn off wifi when the screen is off. I have updated, so I'll try without tasker.

I take my earlier comment back, aqdc still has the wifi drain bug, very annoying. Also, the new ipad pro makes this look like a joke. We need an 8895 in this tab not useless qualcomm chips.

I have a EU LTE Tab S3. It's connected to Wi-Fi continually when I'm home. I lose 2-3% when the tablet's sleeping overnight. I didn't know there was a Wi-Fi bug until I saw this thread. But I do have a Netgear R9000 which is a beast of a router. Is there any commonality to the Wi-Fi drain problem? I don't remember which Samsung phone it was but one had a big problem with D-Link routers specifically.

So it's now referred to as "*****ing" when people are noticing a very clear obvious issue with a device and would like to see it fixed. Amazing. Maybe for the S4 they can just not put speakers on it and we can all be considered "*****ing" because we should all just use headphones?
Anyway......completely ridiculous that there are constantly issues with these things. I TRY to switch away from iPad constantly and there is just not an Android tablet on the market that is in the same ballpark and at this point I doubt there ever will be. I've lost 8% of battery life today already and the thing has been on for like 2 and a half hours, and of that time I've probably spent like 5 minutes actually using it. The rest of the time it's just been sitting there, screen off. Pathetic. An iPad would still be at 100%, MAYBE 99%.

Please report the wifi issue here to pressure samsung for a fix :

14H Squeezed out of my S7

With a combination of Amplify, Greenify, BootManager, PowerNap, LSpeed, and TinySU
I managed to Achieve this amazing battery life.
I will try to share my settings ASAP.
(Keep in mind I was on lowest brightness)
I'm on a US SM-G930T (SD820).
Usually when I leave my phone in my pocket battery goes down as if I'm using it, but it managed to pull through.

That's not good battery life at all, 14 hours TOTAL, not SoT
SoT was only 22% of that, so around 3 hours maybe

I think I have good battery life.
See pics.
always wifi on, bt on, location on and data on.

I have an S7 Unlocked US model. There's no 'carrier' bloatware thank god. But I am pretty sure Samsung makes up for it by adding their own. Before I ran three debloat scripts on this thing, there were about 325 apps installed on it. I would HATE to see the additional amount of crap a carrier would add to that.
So after flashing the three scripts, I got down to about 150 (include my apps probably about 165). That's beyond absurd and this type of 'bloat' should be illegal. Samsung, among the other manufacturers and carriers, are literally scamming everyone out of hundreds, if not thousands of dollars by doing this. I have a Motorola Droid Razr M XT907 (Verizon) originally running KitKat. It's been rooted forever. I recently paid Sunshine to unlock the bootloader and I flashed Lineage 13 to it (Marshmallow). It's manufacturer date was 2014. Life span of 1 1/2 years max. I increased it by 5 more at least. If this thing can handle even Nougat (tried that too), then this S7 can run a nuclear generator, but won't because of the crap on it. Bottom line: If they ever say you need a new phone because it's slow, they're scamming you.

Here's my settlement after 24 hours of rooting, debloating, tweaking and optimizing my G930U
- Flashed fresh, stock firmware: Marshmallow 6.0.1, first release, G930UUEU4API3
- Was FINALLY able to gain and hold root by following the steps located in the first section of this thread.
- After that I installed an UPDATED version of FlashFire via ADB.
- I opened FlashFire. Until you disable KNOX, SuperSU will be VERY slow to prompt you with the pop-up to grant root access to FlashFire (maybe a minute or so). Once access is granted, you can debloat and disable KNOX. This is the only root required app I installed at this point.
- In section two of the same thread, I downloaded and added the second .zip file, S7_or_S7Edge_Fixes_Debloater_V15.zip to internal storage (sdcard) and flashed it using FlashFire. I also downloaded this .zip, added it to internal storage and flashed it. I also went here and did the same with this .zip. (KNOX is disabled in the first flash so at this point SuperSU will function normally).
- IF YOU DO NOT DISABLE KNOX COMPLETELY YOU WILL LOSE ROOT!! Flash ALL 3 .zips to ensure KNOX is disabled!!
- I then disabled any other apps and or services I deemed fit and that suit my needs. If anyone wants me to I can compile a list of what I left installed.
- Installed Xposed following the 3rd step in the thread I linked twice already.
- Downloaded and installed HEBF - Battery Saver & Optimizer, selected a medium profile for Battery and medium for performance.
The difference is almost instant. On top of all the bloat, I can't believe how much battery this drains because of it.

Also AppOps <3

Not debloated? I don't believe that.

Check the battery stats thread, 2 days with 3 hours SoT is easy, also depends what you were doing with your phone while the screen was on, if not much, like WhatsApp or something low powered, then you can get way more than that
atm Samsung have caused a battery drain bug with the last 2-3 updates, but before that I was averaging 5-6 hours SoT easily, and could easily get 2 days usage from one charge

With being on unlocked firmware, without the carrier bloat, There were 330+ samsung apps on this thing. I was lucky to get 5-6+ hours on a full charge and it would feel like it was going to melt while using it. I got it down to about 135-140 apps. if you include the ones I downloaded, 161 apps. Installed HEBF battery optimizer and it runs as smooth as possible. I probably could get as much of a charge out of it now. Prior to that? I don't see that being remotely possible. There were too many apps doing too many things at almost a constant level. So i find it very very hard to believe someone got 2 days on a full charge with 330+ apps running in the background. It just isn't possible.

Just because your phone was a lemon for battery life does not mean everyone elses is, go read the battery stats thread and see for yourself, most people get 5 hours+ SoT without resorting to debloating
5-6 hours on a full charge is diabolical, no-one in their right mind would accept that as normal, that's about the SoT you should be getting with the phone in constant use, not entire battery life
And next to none of those apps you removed use any power in the background, there were 2 that used about 10% too much battery for my liking, OM Customise and KNOX, I disabled them and easily got 5-6 hours SoT, at a push I could get more with lighter usage
So don't make statements like "It just isn't possible", you don't own everyone's phone, you can only speak from your own, it is entirely possible and is easily accomplished with a normal non-defective S7
