Legend battery life

Hi to all!
I'm thinking of buying either the Legend or Desire. There are two things that are important to me. The battery life and storing applications on the memory card. I suppose that the latter will be taken care of by the upcoming update to Froyo (if it ever happens!). How about the battery life? How long does it last on the Legend? Would anyone have any experience with the Desire vs the Legend on this? All comments appreciated!
Thanks in advance!!!

I don't have experience with the Desire but my Legend performs battery wise as expected from a smartphone I guess.
After the last update I discovered for example that leaving Google Reader open in the browser in the background drained power, so I now leave the browser always on the google homepage or kill it altogether when I'm not using it and I've seen an increase in battery life.
Anyhow, I give it a pretty intense use, on a work day I listen to podcasts on it for some hours at least, I connect it to my car bluetooth on the commutes (40 mins average total), read email, etc. And it lasts me the full day without problems, usually ending the day with 30% or more battery left.
It obviously depends on how each one uses their phones, as tricks like the Reader one I mentioned can make a difference.

The Legend seems to have slightly superior battery to me. My legend ends the day at about 30 percent after 2 hours of Bluetooth stereo playback, and plenty of latitude use and web browsing. My partner's new desire ends the day about about the same but without the music playing I do.
I was jealous of the desire when my partner bought it but If I had the choice of legend or desire again, it would be a hairline decision to buy legend again. If Legend had live wallpaper I would choose legend without doubt.

My battery life is even better than my old dumbphone. With medium use and pretty stringent management (ie. a task killer, bluetooth and wifi off unless I need them), I can get about five days on a charge.

Are you sure you are using the original battery ? I have never heard anyone reporting 5 days on any smartphone on even minimal usage. Legend seem to give 1 to 2 days max on minimal usage.

I have on two occasion to manage get three days but five days? Naah, not with the original battery.

Well if you disable APN the thing can last 5 days, but with net connection active definitely no way.

I can believe he gets 5 days out off this phone. I can get 3 days out of it with very good reception, some hours of browsing and 20 texts a day. Almost no calling and 3G always on AND WITH A GOOD TASK KILLER I always kill almost every app before putting it in standby you just need to know what you can and can't kill.

I can do 3 days with low use (maybe 10min calls and 20sms a day) and APN off most of the time.
With APN on I don't think it will last more than 2 days max

Just to clarify, I do turn off my mobile internet unless I'm using it at that moment, and yes I'm using the stock battery.

Sure, if you turn everything off it'll last a few days, but then might as well carry a dumbphone

Hey all,
I've been using Azure 1.0 on my Legend.
In case anyone is wondering what battery life is like on this ROM [I know I wanted to know before I decided to run it...] :
I've just got the best usage for this ROM in terms of battery life, since I started using it [0.5].
I haven't gone for Azure 1.0.1, and have stuck to 1.0 as I didn't have any APN issues...

Voice calls = 1hr 3m 15s + SMSing
WiFi = 6hr 46m 46s
For the hours that WiFi was not on, Data [H/3G] was always enabled.
Approx 1hr 45min of browsing

Battery life was pretty poor when I first installed the ROM.
Then I used SetCPU to help....but it didn't seem to help too much...
Now I am seeing better battery life, like the above.
No idea if this is good/bad for this ROM, but for me, its the best I've seen yet....
...though still probably not as good as I first saw on the stock ROM before the update which messed up the stock SMS app was pushed out...

18 hours ~ 24 hours average. 1 and a half day or so if I'm lucky.
2G network. only switch on 3G when it's needed.
Wi-Fi, gps and bluetooth if needed. If not, it's turned off all the time.
always leave my Trillian (MSN/YM/gTalk) turned on almost all the time (like 75% of the time).
WhatsApp for 24 hours.
Mail fetching every 4 hours.
Twidroyd fetching every 15 minutes.
Urbandictionary widget fetching every hour or so.
15 minutes of call average.
Texting about 10-20 times a day.
And data counter widget running all the time.
Rooted and using a nice clean ROM called "CleanEclair 1.6.2"
Got a good Task Manager too.
It's definitely better than my old iPhone 3g.
BUT, if you are asking "Desire or Legend"
I may choose desire for it's better hardware.
PS: Sorry about my bad english.

Just to echo previous statements about battery life, I too get an easy 24 hours from my UK Legend. It usually has at least 30% charge left when I plug it in at night (10-11pm), this is from about 6am. As I type this as 4.30pm it has 69% left.
I leave data and wifi on all the time but only enable GPS & Bluetooth when needed. The phone connects by wifi at home but is in a marginal 2G location when I'm at work (cheers, Vodafone!) so probably has to work quite hard to keep connected to the network.
Google services and Twitter update constantly, Facebook every hour.
Don't run any task killer apps as I found they made naff all difference.
I do watch how many browser tabs I have open and what's on them thought as I notice that some pages really suck the battery dry.
Navigation is the real killer on the Legend (or any Android I guess); the combination of screen on, GPS enabled and heavy duty data use means it can go flat in as little as 3 hours. A power cable in the car will only supply 500mA, rather than the full 1A that a main scharger will, so it only really slows down the drain on the battery.
Other than that I expect the phone to fit my life, not the other way round. The effort that some expend to micro-manage their battery life really baffles me!

I get terrible battery life...
Typically 7-8hrs , now I use it for work but today I did 30ish minutes of calls, + maybe 1hr's worth of reading emails, sending data etc etc etc.
From looking at the "battery" part of the settings/about screen I can see that Display seams to be the thing EATING the battery..
is this normal?? I do use the power widget and put the screen down as low as it goes when I can however im really shocked at the power usage..
Ive tried using a task killer (advanced task killer) and JuiceDefender and neither make much difference...
any comments?? am I being realistic? I used to have a blackberry 8900 and it would easily last me a whole day , doing the same email load, websurfing, syncing etc, might even last 1.5days but I tend to plug the legend in whenever I can....
Is this normal???

Yup. Try lowering your screen brightness and see the difference. Screen and gps is the most battery-hungary.

Everything depends on how you use your phone. Try to avoid GPS and max screen brightness. And always remember to kill aps with any of the app killers, after you finished with it.

Good advice. Except on the task killing. Google around why task killing is not healthy for your phone.

my battery doesn't seem to show the correct level...I can charge it overnight on the mains an in the morning it has only got to 38%. Take the battery out and it goes up to 60ish%. Phone will last about a day, but can't seem to get a full charge into it.

Battery Life Sucks! Android still way behind in this respect.

My last Android phone was the Desire. (The first one)
It's battery life left alot to be desired in all honesty.
Phone after that was an iPhone 4 which had a far better battery life. Onto pastures new after my iP4 got smashed, I picked up a Samsung Galaxy S II as a replacement.
Had it three days now and I am really not impressed with this things battery life. Unless your camped near a charger it just feels like such a pointless device. What's the point in having all these features if it's going to be dead by lunchtime? Really?
Got hardly any apps installed, have closed down social hub and everything inside it, no notifications or syncing apart from Gmail and contacts. (Whoopy doo!)
I took my phone off the charger around 2pm at 100%.
Now it's showing as 6h 48m usage (doesn't sound right)
Display 44% - 1h 47m use
Internet 13% - CPU total - 19m
Cell Standby 11%
Android System 9% - CPU Total 3m , CPU foreground 1m , Stay awake 4m
Android OS - 8% CPU total 11m
Voice calls - 3% - 2m
Battery now at 48%
So over 50% battery and I have got 19 mins of checking football scores and 2 minutes of calls.
This phone is not worth £500. Not in the slightest, just based on this. What good is a dual core powerhouse if it's going to be dead before you've had a chance to use it?
It's a serious issue that needs looking at, and no , it isn't the Android OS bug. That only accounts for 11 minutes of nearly 7 hrs of being on.
I use to charge my iPhone 4 up about once every 3-4 days, it never seemed to ever die or drain this quickly. You put the phone on the side and goto bed, usually lose about 1% of battery for the entire night.
This just isn't good enough for the price being paid.

From what i've seen here at XDA is that every phone (even the same model) performs differently. My SGS II can sit on my nightstand all night (7-8hrs) and only lose 3-4% battery. I can go through my entire work day of 8hrs with email sync on, sending text, making calls, checking XDA and Twitter, etc and still only use approx. 30% battery.
This is with the stock ROM. With a custom ROM that will improve and I can count using a maximum of 3 fingers the last time I was away from a charging source for more than an hour so i'm content.

You must be the only one I've heard of that only charges their iPhone4 every 3-4 days, everyone that actually use the phone has to charge it at least every day (that I know anyways).
And 19 mins checking fotball scores and 2 calls? Your screen was on for nearly 2 hours so I hope you got to do more than that.
I can usually get a solid 5-6 hours of _active_ use time out of this phone and that's better than any phone I've had before at least. But one must remember batteries are batteries and the one in SGSII only has those 1650mAh to work with, it isn't magic.
And if you're getting much more than 1% battery drain per hour you have a bug or a program eating your battery somewhere.
Oh and if it isn't good enough for you just return it or sell it, it's not like anyone forced you to buy it or like it. I would never tolerate having a phone I didn't like, it would go straight in the bin.

Honestly, there isn't much choice is there. It's this thing , or the iPhone 4.
Blackberrys are rubbish, other mainstream phones are all Android based and have battery grievances aswell.
Battery life is such a limiting factor with these modern phones, the old nokia bricks use to last ages. I know they can do alot more, but I figured disabling all of the sync features and what not should atleast improve it a fair bit.
Doesn't seem to make any difference.
Going back to carrying spare batteries again, just for daytime use. lol

19 mins of CPU usage doesn't mean you was checking scores for 19 minutes, but it took summarily 19 mins of 100% CPU usage. Plus if I look at display time then I think you was checking these scores for about 1:40 hrs and now you're surprised that it took ~50% of battery. Also I think you have brightness set to high, because display should not drain so much power.

Mine was up to 1 day 6 hours then I had the charge message on screen this was with a few hours of phone calls, maybe 35 texts, watched a bit of a video, web browsing, I am very pleased with the battery so far.

I get at most 15-20 hours out of my battery, limited use.
As many stated before, the phone is almost useless due to the bad battery. I dont know if I can see an entire Mkv 1080p movie in it. Only seen a few CSI 720p mkv videos, and they drain the s**t out of the battery.
Looks like we have to buy the big battery pack thats going to be released soon. Then it wont be so thin, or light though...
Here is a pic of my stats, phone is about to go dead in a couple of hours. That means Ill get about 15 hours out of it today.

First of all, your display was on for 1hr 47min, 13min of scores doesn't cause that....
Second, there are ways to get better battery life out of the phone.
Turn down brightness
Turn off auto sync
Turn off radios if they can't get signal
Dont stream videos/music
But why have a top of the line device if your going to do all that?
I turn my brightness up, I love the sexy giant screen. I auto sync 4 email accounts. I have 7 screens filled with power wasting widgets. I constantly stream pandora and watch espn at work, tvshowstream on lunch and in car. I overclocked also.
Lets say I use my phone to its fullest. All I did was buy some cheap hong kong batterys on ebay for $11 and switch them out as I need them. I can do anything and everything on my phone with confidence I won't run out of power.

What did you install on your phone? I'm still running full stock

Its not the best battery but it ain't that bad as many others, iphone 4 is good on battery and lasts a day or 2 with some use but ios is nothing like android interface so they carnt be compared that easy, i think there's room for improvement weather its a android update or custom Rom.

I used to have an iphone 3 and I had to charge that baby every day...
While I would certainly like more standby time... Having an awesome computer in your pocket is way cooler than a dumb phone that's battery lasts four days.
I think this was one of Nokia's major miscalculations... That users wanted better battery life over phone features.

Not going to waste too much time with this, you picked the wrong phone to begin with, Samsung has this goal, to be in every pie. Their products have great reviews, but so research first and find a company that does better, one that actually takes the time to develop the product they primarily specialize in, and who have been around doing it (reliably) for awhile. I.e. Motorola, Htc

I actually went by reviews, they all point to this phone being the best alternative to the iPhone 4. Comments were generally that battery life was good.
Think their reviews were all based on ten minutes of use.

Which samsung phone do you have? I would have to agree with HTC but motorola for smartphone? HAHAHAH

I dont't think 19min of checking football score and 2min of calls will even affect your battery life. 6hours and your battery down by 50%, not sure what you did to your phone. Just watched live football stream for 2 hours, everything else syncing etc, I never off background data, wifi constantly on, lots of widget and now after 19hrs I still left 28%.
If this phone were not good enough for you why don't you return it and exchange back for an iPhone4?
ps: My gf ip4 need to charge every 2 days (with light usage) but when shes playing lot of games and browsing, she will need to charge it at night before going to bed.

If you don't like the phone return it and get something else. That's some free revolutionary advice for you. No need to create another thread for this, you could have just made a new post in one of the others. Now have a good day.

Nexus S vs iPhone 4 on BATTERY life only

Considering moving back to Android for native Gmail... (Not sure if I'll wait for the next Nexus model to come out or go for the current one...)
I went from a HTC Desire because of the crappy battery life I was getting to an iPhone 4 and have been more than happy with the huge improvement on battery life. Has any one went from an iPhone 4 to the Nexus S? If so please comment on battery life.
For some background info on my iPhone 4 I listen to 2-3 hours of music, send a bunch of texts, a few emails and some light browsing/app use as well as leave 3G, GPS and WiFi on 24/7 with screen on auto brightness and charge my phone over night - it usually has plenty of juice by the time I am going to bed (any thing from 20-50% depending on how much I hammer it).
On my HTC Desire I was having to topup the charge every day in work. Does the Nexus S do any better?

I find the battery life influenced most heavily by the amount of time the phone spends on 3G data. If you are connected to WIFI, it can last significantly longer. I'll describe my usage before the last recharge, which lasted 46 hours with 4% battery left.
I started with 100% charge at night, turned on airplane mode during sleep. I had both 3G and WIFI turned on the second day, however, connected to WIFI. Didn't use the phone much the second day, except I listened to Music for an hour and watched a video for half an hour. Of course I do check emails from time to time. The third day, just a bit over 24 hours since last recharge, still had about 70%. Listened to music for an hour in the morning, watched videos for about one and half hours through out the day in total. I checked email from time to time using WIFI and sent a few texts. By night, I had about 7% left, with a bit browsing, it dropped to 4% before I plugged it in. Skype has always been on while connected.
My experience overall, the phone can easily last a work day without problem, provided you don't use 3G data a lot. You can drain about 15~20% just by browsing for an hour on 3G.

I charged my phone over night and in the morning took it to uni with me. It only lasted me 9 hours with a bit of Angry Birds in between and somewhat constant messaging on Facebook with WiFi. I'm really disappointed although my phone is new (5 days old) and someone on the forums said it took their phone 2 weeks to start giving decent battery life.

I usually get around the same battery life on both. I currently have a nexus s and an iPhone 4 that I change between. If you use auto brightness and stay on wifi whenever possible you will get decent battery life from the nexus.

I get pretty good battery life with the nexus s. Emails, some calls, some angry birds. Most of the time on wifi though. It usually could go for a day and a half before getting to around 20%.

A bit of a thread dig - how do you guys find it now?
I've just gone from an iPhone 4 to the Nexus S (i9020, AMOLED) and I am finding the battery life shocking in comparison.
I used to be able to get through a day quite comfortably with heavy usage on the iPhone4, but now, I have to lessen my usage and even then, it struggles.
I use 3G data quite heavily for push-mail and reading forums, and I'm not sure if it's just the fact that there are a large number of white screen pages, or whether it's just poorer hardware/software management.

I had both iPhone and Nexus s, on the Nexus S, I have a spare battery that's good enough for any daily usages. On the iPhone I use a spare charge battery that's loosely connected and quite inconvenient.
I don't throttle down neither phoned and I use 3G/WiFi all day. The Nexus does last longer.

If battery life worries you so much just stay with the iPhone I have an iPhone 4 and nexus s, and I use my iPhone more then my nexus sometimes and battery life is not impressive at all I get to 20% on my nexus with text SMS mostly and some calls and I get to like 35% on the iPhone 4 with a lot tweeting, Facebook , SMS , browsing , YouTube , etc .... I love android but damn battery life is disappointing and probably is because of the multitasking is more in depth then iPhone 4 but the multitasking on iPhone gets the job done, it could take like 10 seconds to to see my notifications updated on Facebook for android while it takes 1-3 seconds on iPhone , I probably jump full ship to iPhone but I hate notifications on iPhone I can't wait for iOS 5 , apple best moved was to copy android and windows 7 lol. I like to take a lot videos and pics and iPhone does the better as well... I guess if gmail is the only reason you moving to android back just stick with iPhone 4
Just to show you after 16 hours (heavy use)

My nexus s die Just at 7 o clock been charging for an hour and not even 50% left

Auto brightness kills the battery faster . I easily get a full day with constant usage. When I hammer it, I get about 9 hours. Battery life could definitely be better but android does a lot more multitasking than the Iphone which is why the battery on these phones last so short, lot of crap in the background constantly.

If you want different notifications, jailbreak your iPhone and install MobileNotifier. It's a great notification system and very non-intrusive. Otherwise there's NotifiedPro which is quite good as well.

Jailbreak on iPhone is easier than rootin an Android device
IN other news - really quite fed up with the battery life with the Nexus S. Finished charging at 2pm, by 6:30pm it's already down to 60%.

The iPhone 4 pretty much crushes all Android phones by a lot when it comes to battery life. Best off getting a second battery and wall charger.

I'm not sure what "more multitasking" really is.
What benefits does it offer? On my old iPhone, my chat client, pandora, gps, or whatever app needed to be running while I switched over to something else kept running.

Turn push email on the iPhone to 15min and you'll see that the battery is similar to nexus s which is pushing email to ur phone in real time.

It is not multitasking as such, it is mainly the screen size (3.5" vs 4" is significant) and poorly written applications.
Actually it is not so simple.
A lot depends on the screen technology of your nexus and the apps you are using. For example, samoled + black text on white bacground could easily mean two-three times more battery drain than exactly the same app on the LCD screen.
Another common culprit are many seemingly "innocent" tools/widget which make phone to wake up. For example, the data traffic counter on my phone was responsible for quite signifficant battery drain, but never appeared on the battery statistics since it woke up frequently and triggered the drain in other components.

I had set up Google Sync on my old iPhone and each email was pushed to me in real time. Battery life still doesn't even compare.

Not all apps stay running in the background on the iphone, they freeze when you switch. As far as I know only a few native apps and some dedicated don't freeze on the iphone like pandora, everything else just freezes in time until you come back to it. Most people have a ton of crap running in the background constantly and don't even know it. Most apps are preset to refresh as fast as possible as well. And as others have mentioned screen size and technology plays a major role as well in battery drain.

The IP4 will have slightly longer battery life.
But, with the NS, you can keep a small light spare in your pocket and swap out, doubling your battery life. With the IP4 you either need a charger or plug it into a bulky external battery pack for a length of time.

Battery DRAMATICALLY Affected by Brightness

**PLEASE READ THE TITLE**
This is not a general battery life thread. I'm looking for comparisons of brightness levels. Thanks.
ALSO: Has anyone noticed a difference when using black themes/wallpaper, etc. I have NOT noticed any significant difference.
Ok, first off, everybody knows brightness affects battery use. However, I've been trying to run my brightness at 30%, which seems pretty low. I figured that can't use much more power than 0%. Still, I've only been getting to about 2pm after charging my phone all night. I'm a heavy user, I like to tinker with my launcher a lot, check facebook, texting, etc.
Today I decided to try 0% on the brightness setting. I'm not crazy about this since it's not bright enough for most situations. I mean, I bought a SAMOLED+ phone for a reason. Anyway, the battery usage seems to be DRAMATICALLY less than with 30%. What's even more odd is my battery usage shows my display using 40% of the battery instead of 50%, which is what I normally see. This isn't a very significant change.
So what about everybody else? Are you guys having the same experience?
UPDATE: I'm up to 7 hrs now and have 67% battery left. Screen on time 1h 26m. This is a dramatic improvement still from 30% brightness.

Ive had my brightness at 100% for most of the day. Im getting great battery life. Im a heavy user and I can get atleast a 1 1/2 days with a single charge. Luckily I hve the luxury to charge over night.

You sir are not a heavy user if you can get 1.5 days with a single charge on 100% bright.
Or maybe a heavy user on calls not browsing or things that use the screen.
on 100% simply 1h browsing, 1h with video, 1 account sync, texting, some calls, check twitter and fb will kill your battery in less than a day, and that is not heavy using.

Can i ask how many hours you have your screen on,
because with 100% brightness i'm lucky to get 3.5 hours (internet/games/twitter) of use out of my phone.

copy and paste from another thread I posted in. This is a very typical day. Now I dont use my phone as much after 6. My phone is currently at 30% from a full charge from friday night.
I make it during the day with 100% brightness. I consider myself an a heavy user.
Ill show my usual day after the new factor wore off.
Unplug at 630-7am
Start my music through Poweramp around 9am at work.(20 gigs of music)
about 20 text/ 30min total of calls
20 or so emails with some attachments
Usually download about 200mb of music/videos throuhout day
Check about 10-15 websites every couple hours(xda app most frequently)
Use Logmein about 10-15min total
Play LIVE holdem Poker roughly 30min total
Youtube/video watching
Some other random things I cant remember
3g/h+ on all day
wifi stays on
brightness at 100%(bright orange/blue wallpaper)
Browser brightness is at 50%
Everyones experience will be different. My original Samsung galaxy s(vibrant) would be dead around 5-6pm. My Galaxy s2 is around 40-50% around 5-6pm. Im experienceing great battery life. My fiance iphone4 would kill my vibrant in battery life, but the sgs2 is on par.

Yes, I too find this very hard to believe. I know if I watch a high quality video on YouTube the battery drain is insane. Of course that is data also but I doubt I could get an hour. My guess is if I just left the screen on for 2-3 hrs my battery would be dead from 100%.

Nope, that's definitely impossible.

I don't believe you, period.
On my s2 I lose 30-40% in 2 hours of not very heavy use on auto brightness. I am shocked that when I surf I can see the battery number (using battery guage) actually ticking down. Device is nice but battery life for me makes it totally useless for a prime device.

I've got display at auto-brightness which is usually around 30% for me indoors. Got display on time of 4hours 16minutes..includes about 45minutes of 3d gaming (modern combat 2) and rest browsing/downloading etc..
total up time 12hours 39minutes...and got 22% left...thats incredible to me, coming from a desire hd, I cant believe my phone is actually still running haha..
EDIT: Oh yea forgot to mention, I got a new replacement yesterday which means I havent even gone through the charging cycles yet, my previous one was superb aswell so fingers crossed this one will be too

Im off today so my typical use is different. Ill repost my battery stats when I get home after work tomorrow.

Well this is helpful, thanks. Sounds like you are getting better battery life than me. Although I would say I definitely am a "heavier" user than you. I used to make it to about 3pm with my GS1. I'm getting about the same with my GS2 if I leave the brightness on auto. That's if I don't use YouTube for more than a few min. I too would like to know what your screen on time is at the end of the day.

Sorry, posted this in the wrong place

That use and that battery it is simply a lie.

The screen is definitely a battery drainer. Don't set the screen to 100% brightness and record 1080p videos. Battery level will be at 0% in less than 2 hours.

Why the f would I lie? Samsung is not paying my bills nor cutting me a check. ill post tomorrow after work my battery stats.

That is impossible on THIS phone with THIS battery! Period!

I'm waiting for those stats.

A screen shot of his display on time along with the graph is what's needed.

Can we get back on OP's original topic of display brightness vs battery life discussion, this is a topic I'm interested in as well as I leave mine on auto-brightness and display is always #1 on my battery consumption list.
Maybe intruda can start a thread called "How my battery life is superior to everyone else's SGS2" and the dissenters can go there and call him out. Just sayin'.

This is my usage today with auto brightness. Mostly at 30%-40% brightness with 45minute gaming and rest browsing. Music. Youtube.
Im impressed.

Post your battery life info *stock rom only*

Hey guys, I'm using the iPhone 6 plus now and I'm seriously thinking about switching back to android. Just can't stand iOS. My only concern is the battery life since I got excellent battery life on the 6 plus. From the reviews every reviewer says it's very good battery life but I need to hear real experience from actual users here. How is the standby time? Screen on time? Please stock rom only and please post screen on time and overal battery screenshot. Thanks!!

Standby time? Lol I've been on it too much for that. Battery is excellent don't sweat the move from iphone.

My iPhone 6 plus has exceptional standby time so it gives me a feeling that the battery is endless. For example, how much juice does the note 4 lose overnight? (7-8 hours)

Bluetooth and wifi always on, pebble connected, poor coverage area. I keep it set to pick up lte when available, but I only have edge where I live. I travel a lot though and still get good life when I actually get lte. I haven't tweaked anything (yet). Be warned that my first charge gave abysmal life. It wasn't until the second or third charge that I started getting decent life, so don't worry when your first charge runs to nothing after 8 hours.

Amen. I use powersaving, and you could always use the ultra power saving in a bind.

Around 0 to 1 percent. Maybe 2 if I get a bunch of notifications. My fiance has the iPhone 6 plus, trust me my note 4 destroys her iPhone in battery. With light to moderate use I'm easily getting 2 full days ( I send roughly 500-600 texts, maybe 20 emails, at least 20 phone calls, navigate to appointments and I'm always on pandora....also I have a moto 360 connected all day). When I'm doing heavy usage I get about 24 hours or so. But my heavy usage is actually HEAVY. I can almost guarantee you don't use your phone more than me. You will be fine with battery life.

Thanks for the info!! I glad it does well with Bluetooth since I might buy a smart watch later. I intend to let Bluetooth and gps on,plus streaming a lot of spotify. Time to ditch the 6 plus.

Brightness at 50%. GPS on, Sync on, MultiWindow on.

Excellent battery life. I use my phone almost all day and night. FB, messaging, music, texting, phone calls, camera, reading, photo editing, youtube. I use it extensively on a daily basis during the week. On weekends I don't use it as much so I have more than half charge by Monday.

I turn on power saving mode at 100% when i go to bed, and when I wake up 5 hrs later I'm usually at 99% or 98%. Without power saving mode, I wake up to 96%.
I can easily get through a full day at Disney World (about 8 hrs) with light usage - mixed use of wifi and 4g, checking the disney app and checking my farmville farm, and checking feedly. I usually leave Disney with about 50% juice left. Brightness on auto, wifi on, bluetooth off, gps on.
I've tested streaming as well. On 4g, starting at 100% charge, I can stream about 4 hour long episodes on Netflix, on Plex it's usually a little longer than that before it hits 50%. At home on wifi, I can stream about double that amount before hitting 50%.
I'm pretty happy about the battery life, and the best part is I can always remove the battery if this one goes bad, or bring spares on trips. I can live with Touchwiz if it means I can have removable batteries, sd card, and the pen.

I've done multiple tests on this. I will charge it up at night 100% then leave it off charger for the night, look in the morning. I'm averaging 3-4% discharge per night which is not too bad. My Nexus 5 was a ridiculous 10-15%. Still nothing close to iPhone that just doesn't go down if you don't use it.
I leave all things on. Don't really want a phone that acts like a 2002 device.

Hey all,
Ok So My battery is at 23% with 4 hours 45 min of screen time and it's been of the charger for 1 day 20 hrs 15 min and 20 sec

The phone charge so fast and it is amazing. I dont know if I want to do that in the long run bc fast ch arging is bad on battery!
I have a nice battery charger and it says charging the battery slow will last longer per charge and longer life cycle itself too.
So what do you do?

I returned the iPhone and have used the Note for 2 days now. Battery is... Well, not as good as I expected. At least not comparable to the iPhone 6 plus. But I don't sweat on this since it does take quote some time for Android battery to kick in. I kinda wish Samsung didn't push the pixels since it's truly a battery drain. Also the GPS drains battery too. These 2 functions on the iPhone are very efficient.
And yes fast charge is wonderful. I say don't worry about the battery since it's fairly cheap.

Simple fixes.
1.) Make sure you screen brightness is on auto
2.) Put on a background that is dark, or mostly black
3.) Set your location to device only (GPS only)
4.) Turn the run time to ART
You will easily see an increase in battery life.
Below is my normal battery life. And an example of a good background to use.
Had about 5.5 hours of screen on time.

I actually switched from GPS only to power saving. I have quite a few email syncing tho. One interesting thing... Are you sure we should be on art? I heard its not fully compatible.

ART bogs down my phone so I don't use it. Also during boot up, it take forever to finish as it tries to optimize some apps every time. About 39 on mine. This makes my phone super hot and there's no way to bypass this process. I say ART is a bad idea.
