Terrible Battery Life!

I got my Vibrant a few days ago and as of today i can only get 4-5 hours max out of the whole battery and thats with heavy to moderate use.. does anyone else seem to have this problem.. im gonna return the phone and get a new one but does anyone else seem to have this?
I really dont understand why this is so bad..

4 or 5 hours of heavy use is about all I get. That is if I'm constantly messing with it. E.g. web, email, facebook,ect. However I think this phone has excellent battery life when I'm not constantly playing with it. Wifi definitely drains it quicker. And stupid apps like facebook. I periodically mess with my phone throughout the work day and by the time I get home I usually have about 75% battery remaining. I think that's pretty good.

THE BATTERY IS TERRIBLE. thats why i returned it, and the slow acrolling from screen to screen with stock software

I think you can only expect about 4 hours of awake time use on this phone. I haven't had much trouble with mine, I get about 13-14 hours per charge. But my phone its idle 9-10 hours of the day.

Then why are you still in the vibrant forums... move on...

I would think by now people would be use to the type of battery life you get with these types of phones. With heavy usage your not going to last all day just how it is until battery tech catches up to phone tech. I use mine a above moderate usage and some days heavy usage. From when I unplug it at 7:00am the battery is down to about 10 to 15% by the time I leave work at 4:00pm. Thats a lot better than my HD2, Cliq, MT3G and G1.

I agree 100%. Im seeing a lot of this. One thing I dont see is the "Vibrant Complaint" forum. Can't understand why ppl feel the need to come back in here if they dont like, dont have or feel they need to bash the phone from their experience. Get rid of the phone or keep it and be patient, its that simple... or am I missing something?!?!?

Im almost in the same boat, much better battery life then my G1! I can get from 8-8pm with moderate usage and music palying for the last hour. I was experiencing horrible battery life (8-2/3pm) when I was running notifications with Bloo 1.5.apk, auto brightness on, and Advanced task manager running. Now that I have cut the notifications from bloo (got gmail for this anyway), set brightness to manual setting, and got rid of the task manager I am regularly seeing, after bering unplugged since 8(its now 1245) and im @ 85%. Try trimming down the services you have running in the background and by an extra battery or a car charger.

Id like love to try mine out when i get it tomorrow because with
Mytouch Slide, i had Facebook, Gmail and all the usual stuff syncing and it lasted me close to 8-12 hours of Web, texting and just playing around with it throughout the day.
The Nexus One Was the same lasted me some good 10-14 hours a day syncing the usual stuff along with the weather and such. So Id expect the vibrant to be the same, or Else im returning it and thats the end of it. That also goes for lagging issues as well. And most likely get a different android phone or go back to the N1 and Switch Forums....

Have you ever owned a Smartphone before? Thats normal if you are using it heavily.

no its not normal.. ive used my MT3G with heavy use gives me at least if not more than 7-8 hours use.. what i dont understand is why the hell it takes so long for my battery to charge.

I get 6-8 hours.

I think 5 hours of juice is really good relative to your heavy usage. I always get 15 - 18 hours a day. That's with moderate use. Even playing a game of Armored Strike for an hour. This is the best battery i've had on a phone. I can easily get over a day and a half or even more once I settle down and stop using it so much more than I need to [ because I just got it.... ]

If this is what you consider to be terrible, I don't mind how terrible my battery life at all. I made a few calls, used GPS a few times, always listening to music.. some market downloads, pictures taken. SetCPU at 1000MHZ 100% of the time.

Disable Google Talk. My battery life was excellent (typically all day on full charge with heavy use). I signed into google talk one day and was lucky to get 4hrs before charging was needed. I deselected the auto sign in option and killed it in the running services section. Battery life has gotten so much better 70% after 4.5hrs.

i think the battery life for my vibrant is pretty epic. when i went to cm5.0.8 and cm6 on my g1 i calibrated the battery and thought i was getting really good battery life. then i got the vibrant. i could probably make it two whole days without a charge with how i use my phone (probably moderate-light compared to most on here).
but one thing i do agree with is this phone takes FOREVER to charge.

Hmm.....
Ok.....well I consider myself a moderate-heavy user...
On that note, I actually use my phone for work calls, emails, plus personal calls and emails as well....and i'm an avid gamer and already have many games on my Vibrant and use it to play them regularly.....then there is the fact that I travel for work....a lot, so I constantly using google voice search and maps to find where i need to go (never use the gps though)....I used the internet all the time, especially on WiFi (higher battery drain)....and don't get me started on the movies, music and youtube....plus while at work I have Pandora running from my phone throughout the day....
So how is my battery life? I unplug my phone every morning at 9am, with all that use I don't need to plug it in again till 10-11pm (12-14hrs!!).....by that time of course the battery level is at 5-15%.....But I'm definitely not complaining....
I do however disable the auto-brightness feature....AND turn down my brightness to about 30%....50% brightness cuts about 2 hours off of the battery life....
But a GREAT PHONE!!! Loving my new Galaxy S Vibrant

yeah, i feel the same way. As far as phone taking forever to charge, are you using the usb-computer charger or usb-wall? The usb-computer can be very weak depending on your system.
Charging from pc, i would wake up only to see 65%. That's pretty crazy. On the wall charger, it takes less about 4-5 hours every time.

Anyone loosing like 6 percent in the first 15 minutes after a full charge? 15 minutes ago i was 100% now im at 94....

I get better battery life than i got on my G1.
These are not cell phones... they are tinny laptops that you can press against your face and make phone calls.
This thing has more features than the $1200 gaming PC i built 2 months ago.

I had bad battery life the first day. Turned the phone off late at night and let it charge full. Battery has been wonderful since then.

Battery life

Has anyone seen awesome battery life with this thing or is it just me!? It's been off the charger for 4h20m and the battery is as 87%. wifi off, gps off, bluetooth off, sync ON. just text messaging all day, maybe 20 texts total (slow day today). little bit of facebook, little bit of email, thats about it, so i didn't really do much with the battery but even so with this kind of use my evo would probably be down to around 70%.
battery indicator pro says the display is responsible for 64% of the power drain and cell standby is only 12%, whereas my evo usually had around 50% cell standby and display was only like 8%. was the evo just really bad at holding a signal or what? my display is at middle brightness, if you use the power control widget.
can anyone else tell me how much % their display uses? and what their battery life is like?
after typing this post it's only dropped 1%. word.

Personally, I don't have much of a basis for comparison. I just got my Shift on an upgrade from an aging Samsung feature phone. I've heard all about the horrid battery life on the Evo. My brother has one and can't get a full day of use.
I was out with a real estate agent looking at houses for 6 hours yesterday. We used the GPS a little bit. I was checking NFL playoff scores every hour or so. I was also texting/emailing lightly. 4G was off. By the evening when I put it back on the charger it was still in the green. I didn't look at the power meter specifics... wish I did.
And today I'm just about to leave the office right now. I'm at 8 hrs, 59 min since unplugged with 6/10 green battery bars. (Hey... how do I get the exact percentage? Thanks!)
Display is 62% of my usage (It's set to Auto-brightness). Android system is next at 20%... Light email/texting use all day long at work. Played games for 30 minutes during lunch. Downloaded some new apps (using 4G). Wi-Fi and GPS off all day.
Overall it's a little better than I expected. But I know I haven't really had a heavy day of use yet.

Battery Indicator Pro is a great app that runs in your menubar and displays the percentage for you.
glad we're on the same page with the display, though

I almostmreturned the phone. My cycles were:
1st 8+ hours
2nd 4 hours
3rd 2 hours
Did a factory reset on the phone and it has started to turn around.
4th 9:40 min and at 30% when on the charger
5th 10:46 and still going. Battery is at 30%

I've recharged twice since I got it on Saturday. This seems great, coming from the sprint hero

Exactly. My hero sucked. I used my phone lightly and had it without a charge for over 24 hours. Did some playing around setting it up and then some light texting, emailing, and 4g usage. Then turned off 4g. Amazing.

This isn't your dream phone, it's the one after that. You gotta take it out and play with it more!

I've had to charge it twice a day since the sixth, battery life has been terrible.
I have all the stuff disabled, it just seems to drain even when nothing is running.
I did have an issue with terrible signal on the first day, once I did ##DATA# it fixed it, but my battery life is sucking it up badly.
Sent from my bathroom, with toilet paper.

Just got my wife a shift earlier today and ran it down from the half life that came with the battery in about...6 hours. That was with near constant use, the screen on max, wifi, and sync. Plus GPS on for awhile too. Compared to my epic which with similar use can go...maybe 6 hours from full? It depends. I'll be comparing her battery usage to mine over time and I'll post after she gets some use from a full charge. Under normal usage I can get up to 28 hours from my Epic so people reporting horrible battery life must be doing something wrong or have a defective battery. I fully expect her to get a couple days life out of each of her charges though she'll probably throw it on the charger every night.

anyone have an explanation of why the screen is the largest amount of usage under battery stats? yesterday was an average day for me and the display was something like 50%. on my Evo cell standby was always the highest and the display was down around 8 or 10%
edit: this morning the phone has been unplugged for an hour and a half and cell standby is 50% and the display is 11%... *scratches head*

I just switched to Sprint a couple days ago and got an EVO 4G; I am really unhappy with the battery life and though I got them to give me an extended battery for free it still seems like it's dying very quickly. I am a heavy data user and it's driving me crazy; does anyone have any experience going from the EVO 4G to the Shift and, if so, what are your thoughts, particularly in regards to battery life? Is it worth the loss of size and cameras?

i went from the evo to the shift (30 day swap deal) and i haven't even looked back. the battery life is STELLAR as far as i'm concerned. the evo sucked down power like nobody's business. i'm sure if you got an extended battery for the shift it would last you 2 days at least.

All I gotta say is my extended battery experience is amazing. I get about 36 hours out of my evo. Yea it looks a little fugly now but fck it I can abuse it as much as I want too with battery to spare.

Sent from my Evo while i should be working

I just got the extended battery and haven't charged it overnight yet, but so fast I am very concerned that it is not living up to expectations. However I won't make any quick judgments until I've seen how it does over a couple days.

My Hero got better battery life.
Sent from my PG06100 using XDA App

Typical use for me is pulling the phone off the charger at 5am, light to moderate use throughout the day (texting, facebook/twitter, apps updating ~2-4 hours, etc) and then putting back on the charger at 9pm.
I upgraded from the Hero. The Hero was rooted and running AOSP w/ modified kernel and collin's battery tweak. Battery life was impressive, but performance was an issue. I could routinely get 30+ hours battery life with the type of use listed above (battery was usually 50% or more when I'd put it back on the charger).
With the Shift, battery life is surprisingly good. For some reason I lose ~10% within the first hour, but after that, it seems to settle down and by the end of the day I'm still at ~30% (with the type of use listed above).
Based on what was possible with the custom ROM's and kernel tweaks for the Hero, I'm excited to see what the community can do with the Shift once we get root.

That first 10% drop seems normal for the new HTC phones. I know the Evo does the same thing. Just the way they're charging the batteries

I found this article helpful in understanding the ~10% dropoff when first off the charger.

At what setting do you all have your screen brightness set? Do you use the auto-brightness option. I find consistently that the overwhelming majority of battery use (according to that screen in the settings) is from the display.

I have mine set at 20% and it still looks bright to me.

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.

:firstworldproblems:

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.

Battery DRAMATICALLY Affected by Brightness

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.
