[Q] New GS 4G user. Help with battery problems.

Love the phone. Only complaint that I have is the battery life. I only get about 10 hours of normal use before it dies.
I have it rooted and I have installed Juice defender and setCPU. I have no idea really how to use either of these apps though.
Can anyone please help me to install and set up the apps that I need to get the best power/battery life ratio for this phone?
Thanks.

A really helpful tip is to use black backgrounds. This reduces the amount of pixels on the screen requiring power on the Super AMOLED display, and will improve battery life significantly. Tower reception is also a big one, just turn off mobile data when you get to a low signal area.

I suggest turning down the brightness to the lowest indoors and then bringing it up a little outdoors. 10 hours is really good compared to the 4 hours I got on my old 4g.

I second the black background.
I also installed widgetoid, created a widget with a shortcut to the mobile network settings.
I have Network Mode set to GSM only (Edge Network) throughout the day. This is fine to keep my email syncing and for phone calls. If I know I'm going to start browsing the internet/ streaming music/ etc then I go and set the network mode to Auto to allow 4G connections.
With a few phone calls and a little bit of internet usage I still had about 60% battery life left after 12 hours off the charger.

juice defender works wonders. Set profile to extreme. Choose carefully and let app do this rest. It auto shuts off data when not using 4 apps. I have been off charge 9:40 mitutes with 79% battery remaining. I've been on the market made a few phone calls, browsed the internet and getting and receiving text + emails coming in. Have settings GSM only until I need 4G speed. I don't need a charger because I get through the day easily.

Thanks
I just wanted to say thanks everyone for the tips! I know more is coming from other users but i'm new to android i switched from Windows Mobile 6.5 and android is better so far or atleast for the week i have had this device. i was getting upset with the battery life and always taking my charger with me(i never had to do that with my custom Rhodium. the black backround idea does work very well. I have also found if you set your backlight timeout to 1 min it helps a lot.

you call 10 hrs a problem??
I can tether my Xoom for 2 hrs and listine to pandora over bluetooth for another 3 before it dies... my last phone could berly stand 45mins of pandora over bluetooth before crapping out

Always hated the idea of black backgrounds on beautiful 800x480 screens. Anyhows I had the very same quick battery death too and fixed it. One get Juice Defender, very worth while, second run device in portrait mode [I was an old n900 user so I had it in landscape mode, it did not like staying in that mode]. If things get really bad turn off the WiFi when not in use and change the autosync features to off or disabled. ALOT of power is comsumed by adware communicating with various entities while your away from the device. Genuinely suprused by the sheer amount of adware on the device, nearly ever "free" app is adware [meaning you pay with your usage pattern's etc]. YMV but that all I had to do to get the battery under control.

Im a moderate user and my battery is still going strong

Yep, I'm more than happy getting 10-12 hours of at-office use with WiFi on constantly (including M$ push and personal email) and a moderate amount of browsing during the day. I keep the brightness at "0" as much as possible.
Beats the pants off my N900 which would die in under 4 hours under the same at-office usage patterns.
OEM battery and charger is ~$25 or a Zagg Sparq2 (4 Ah, I believe) for watching hours of video and Angry Birds on those trans-Pacific flights.

You are doing something wrong guys. . .
I'm on a Vibrant /w Froyo 2.2.1 and a 1500mah battery that is now 7 months old.
Battery left says total battery life per charge is 23 hours, 15 minutes.
Now mind you I am a relatively moderately/heavy user. I have 5 homescreens with 15 widgets total on them that refresh every 2 hours, and an intensive live wallpaper.
I use the phone a lot for reading RSS feeds, facebook, texting, and LOTS of music. Total screen-on-time per battery charge is around 3-4 hours with Automatic brightness.
Obviously you have something going on with your phones if you are only getting 10 hours. My phone is also overclocked to 1.4Ghz with overvoltages and I STILL get this good a battery life with all my usage...on an old battery mind you.
Check for rogue apps?
PS: I have Wi-Fi on 100% of the time but NEVER use 3G/HSPA for data since I don't use a data plan. The Wi-Fi is connected 90% of the time the phone is on though since I am always at places with Wi-Fi.

[Q] Help with battery usage / drain, how to increase battery life

Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.

How many hours is your phone lasting on a single charge?

Lately between 5-7hrs one had about 8 and half hours a handful of times

it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later

This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?

I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol

Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.

Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!

[Q] Battery life?

How is the battery life on the MT? If it's poor (stock), have you found a good utility app to help it last longer?

I usually get about 24 hours of battery life on mine. I have gps turned off most of the time and I'm on wifi a lot with light to moderate usage. I did notice that if I have the GPS on, that the battery does go down much quicker. I assume that's because it keeps trying to get a location even when I'm indoors and it's having a hard time.
Although, I've read a lot of people complain about poor battery life so YMMV.

It depends greatly on whether data is working or not. Usually, I'll have around 90% battery 2 hours into the day. But if data isn't working, like today, I'll go down to 80% in as little as 20 minutes.
Usually, I'll have around 20% after 12 hours. Been giving it a charge in the afternoon, and it hasn't been an issue.

I use Juice defender, and it does wonders for my battery life.

I've found battery life to be comparable to other Android devices; with effective battery management, mine gets me through the work day. My wife has the Optimus V and I have coworkers, one with a Droid X, the other with an Evo; my battery life is no better and no worse than any of those devices. With any smartphone you're going to have to turn off unused radios and turn down screen brightness if you're going to be away from a charger for a long period of time.

Heavy use is the real killer on the Triumph. With just the screen on (minimal brightness) and network on (bad coverage), I can drain the battery by about 1% every minute. And that's no exaggeration -- Battery Indicator Pro keeps track for me. I'm working on a spreadsheet to help chart battery drain during different scenarios.

Thanks for all the replies. Basically what I was expecting, but like to have confirmation
Now to find a good place to buy one. Will probably hit Bestbuy due to return convenience and policies.
Edit: Purchased at Bestbuy, and actually ran into Sprint rep who had one I could look at. We exchanged a few geek tips.
One thing I noticed: I have an LG brand microUSB charger, and the phone would not charge from it when turned on, tho it would charge when turned off. I had an older Motorola microUSB charger and it works fine either phone on or off.

I am getting a whole day of battery life with heavy use. I turned off the background data and turned off all sync. Using the email client with one hour pull with imap instead of the gmail client... Couldn't be happier with the phone...
Sent from my MOTWX435KT using Tapatalk

Yeah, I have also found that turning off sync can get you through the day with less battery used.
Depending on how much I use the Triumph, I can run the battery down in about 2-3 hours (with constant use) or have it run all day long and in to the next day (if I only use it for 1 or 2 short calls during the day.)

My motorola Triumph's Battery Life
I have waited months to post my reviews. I had a Virgin Mobile Intercept and upgraded to this the day after it came out.
Battery life is HORRENDOUS. Not sure how anyone can possibly say its "OK". Sure if you are sitting at home or in the office all day, You can continually have it plugged in and charged. My lighter socket doesn't work in my car ATM so thank GOD I don't drive a lot, and for long periods, I would be SCREWED.
Essentially yes if you turn off GPS, Wi-Fi, Syncing your emails and such, etc etc, then your battery will last longer. But what good is the phone then? I have owned many other androids and they worked for almost a full day with moderate usage with ALL of those things turned on and sync'ing (including Latitude and automatic check-ins). I have lost all of that. I have google talk catching up for hours-old conversations whenever I hit a wifi spot that's saved in my phone.
Juice Defender was my "solution" But it has rendered my phone practically useless for anything besides just having a phone handy when needed. No apps, no moe use of all the bells and whistles that I loved about android in the first place!
I am dealing with it. It just sucks. Sure there are other smartphones with similar issues, and poor battery life, but this has to be possibly the worst or one of the worst. It just is highly unfortunate that this is the case.
Also: Bluetooth syncing works 50% of the time. Constantly have to turn it off and on to get my jawbone(s) to sync. God forbid you answer a call and want to switch over to bluetooth. In those cases it works about 20% of the time.
This is not a good phone for people who are out and about all day or drivers of any sort, unless you have it plugged in the entire day. Forget about using it as a GPS unless its plugged in either, that will drain you battery to 0% in less than an hour.
People say this is due to poor design and rushed to market with crappy signal reception and GPS reception, same with bluetooth antennae. This might be the case, I ALSO have mine suddenly have NO BARS for no reason and I have to power off and on the phone to get a signal back.
ALSO half the time I am out and about and need data connection over 3G, even with bars I get NOTHING. It's very frustrating not to be able to use the phone for what I want to use it for.
I will be getting rid of this puppy as soon as possible and I would do it sooner if I didn't want to avoid a 2year contract.
The good part about the phone is it is MUCH faster and responsive than the Intercept and Optimus. Much better camera (has a flash - FINALLY!) and HD video. Front facing camera is nice to have but of course weaksauce in the resolution dept. Overall A+ for effort, D- in execution.

This post is harsh. But I agree with most of it. Overall, the Triumph fits with a prepaid phone reputation: niggly bugs, poor battery life, poor service quality when compared to a higher end device.
The main problem here is that you'll be totally dependent on the community for real bug fixes. Every phone has bugs. But the bugs on the Triumph affect core usability and are on a totally different level. I would not count on Motorola to fix these bugs. If you're the tinkering type and a patient person, this may be worth it. But anyone who thinks that they are getting "something for free" is sadly mistaken. You are paying $25 a month for cell phone service, which is great . But all these bugs will make you pay with your time. How? Time looking for new roms, apps to fix bad battery life, time wondering why the touchscreen response is poor, time working around the bugs in every day life. If that is fun to you (and it may be for most people on this forum), fine. But you are paying with your time. Lesson learned is not to be so quick to fall for the specs. The company offering the phone and their track record of pushing out updates should play a large part in my decision next time.

I usually have WiFi turned on all day, and sync. I use the phone on my breaks and at lunch. When I get home I troll forums heavily and watch netflix occasionally. Not to mention Pandora for at least an hour per day. The battery will last if I dont plug it in until the next morning. Bottom line is that a lot of these issues can be fixed with quality software, and a battery cycle of 18-24 hours is something I can definitly live with. Compared to my Ascend, the Triumph is soooo much better in battery dept.

Battery issues
I am not sure why a lot of people have issues with battery, I unplugged my phone over 7 hrs ago and right now have 57% battery left, now before you hang your head at this look at my usage:
-Over 1 hour of talktime out of 7 hours.
-50+ texts back and forth
-10+ emails back and forth
-5-10 youtube videos
-5-10 pages of web browsing
-dl and install apps
-facebook at least 2-3 times every hour
And some more fiddling around so basically I have been on the phone non stop for 7 hours and its lost only 43%
That said, most of that usage came from the first 4 hours where it lost 36%(1+ hour of talktime, youtube videos im not really shocked there)
6th hour i texted and browsed etc only 5% battery used.
7th hour I just sent back and forth a couple of texts and only 2% battery used.
All this when i dont use any applications like task killers etc..i just let them run the way they want. Also no wifi, everything over 3g.
so imo if it gives that kind of battery its good enough for me. I was really scared when i bought cuz people were complaining so much about its battery but im fairly surprised. One factor that could be though is that I am not running the GPS, no need for it yet, when I do ill update what kind of usage i got.

I get 23 hours battery life with HEAVY usage and 30 if mostly idle. Many may disagree but if you live or work in a Wifi zone, keeping wifi on and setting it to never sleep greatly INCREASES battery life. 3G radio uses more juice especially if low signal or always searching. If you click on Battery Use and see your "time without a signal" is anything over 20% then you will most certainly see increase on battery life if you leave wifi locked on while in a wifi zone.
Also, side note: I have a 1500mah Anker battery that also increases juice time I recommend it!

23 hrs with heavy usage? Unless yours came with a 2300ma battery and not the paltry 1380ma battery, there's NO WAY you're getting 23 hours under heave usage.

I'm using a 1500mah calibrated battery and yep, its true I leave wifi on and set to never sleep when I'm at home or work. If not, 3G absolutely murders my battery. My phone drops between 3% and 5% per hour.

Well today I am having less luck with battery life. I watched two movies on Netflix and constant Facebook. I unplugged at 10:30am and it is now 4:48pm and I am at 52%.. still using 1500mah battery.

I just came from a Samsung Epic 4G. I have to say battery life it at least the same but probably better on the Triumph. The battery is also quicker to swap out on the Triumph. Between the already better battery life and ability to quickly swap, I'm more than happy.

[Q] Battery Troubleshooting/Feedback

I am currently using a Galaxy S3 SCH-I535, stock, unrooted, and have noticed decreased battery performance over-time. I have already viewed many similar threads to try and pinpoint particular issues (wakelocks, troublesome apps, etc.). I was hoping for some perspective whether my battery life is up to snuff.
I have seen many describe their phone life with ~3+ hours of screen time with moderate usage. I use my phone intermittently throughout the work day to chat (Text messages, Hangouts), check e-mail, and browse the internet. I do not use Wi-fi, aside from when I am home in the morning or at night, and make sure to turn it off if not connected to a network. I have sync turned on, but the only accounts I have syncing are Google Now and Gmail. I have location services/GPS/Bluetooth turned off, and run in Power Saving mode with brightness at ~50% and haptic feedback turned on. My reception is subpar, usually about 2 bars and spotty 4g connections at work. I do not stream music, play games, or watch videos during typical use. No facebook, weather apps, etc. that can be culprits some times. At best, with the usage habits described, it is typical that I get 2 hours screen time over a single day (~16 hrs) before I get in the single digit battery %.
I've attached some screen shots I took of battery stats at ~50% drained (I didn't get a screen grab for it but at that battery % I had probably 1:05 to 1:15 hours of screen time). I just started using Wakelock Detector to find any problem apps - after tweaking some apps last week this has been pretty typical behavior. I have even swapped batteries with my wife's S3 to see if it was a battery problem, but did not notice a difference.
Any feedback would be greatly appreciated. Are my expectations for battery life too high? Is this typical, or am I running lower than I should be?

That is pretty good but this comment is by someone who is rooted with a custom ROM and custom kernel since I bought the phone 7 months ago. I can't really say that is the average battery life for the device.

This looks pretty normal to me. You said you had spotty 4g coverage, while your phone is coming in and out of 4g service you'll get decreased battery life. Same happens with your mobile data and Wifi signals if they aren't strong connections.
It looks like your phone is running pretty well. People getting 3+ hours of battery life are either using their phone all the time and hit that threshold in something like 8 hours, have amazing coverage, and/or have no syncing services turned on. A key to run away Wakelocks are having a high battery usage that is coming from something other than your screen, such as media and android system. Other Wakelocks you can't do too much about. There's a thread that is titled the noobs guide to Wakelocks that gives you a pretty good direction trying to isolate Wakelocks and finding fixes for them.
I routinely get about 2-3 hours of battery life in a good coverage area in 16 hours, if I'm in a spotty area my battery will drop much faster. At a friends house with worse coverage I'll be lucky to hit 2 hours. I pretty much use my phone the same way as you.

Shocked at the great battery life on my ATT S4

I have to say I am very very impressed with the battery life I am getting out of my brand new S4 from ATT.
I bought it Monday, and Tuesday was my first full day using it, these were my stats at 9:00pm, after being unplugged off the charger from the morning. 15h 44m with 42% battery left, and 3h 22m On Screen time. That just blows me away, and I was not expecting that whatsoever. I am coming from a Nexus 4 that was rooted with a battery friendly kernel, and that phone would maybe do 4h On Screen time, and be dead in 12 to 14 hours. based off these result, I can expect maybe 5.5h to 6h On Screen time total ?
We'll see how today goes, because I just can't believe those stats above, seems like a freak one time thing to get such good battery life.
All I did was Root the phone, and kept the stock OS on it. Rooting allowed me to install Greenify and DroidWall, Root Explorer and AdAway, my favorite apps. Greenify I used to stop a lot of functions from running in the background, DroidWall lets me pick which apps to never connect over WiFi and 3G/4G network, and AdAway stops the adds of course
I also have sync off on my most things, and any apps refreshing set longer, to like 3hour refresh. I keep screen locked at 50% brightness, and 30 second time off. GPS and Bluetooth off, location finder off.
I also used Root Explorer to delete a sh!t ton of ATT and Samsung .apk's in the system file. I couldn't believe how many items I deleted using Root Explorer, maybe too many LOL Seriously must have been like 30 or 40 .apk's I deleted.
So is it this phone, just much better on battery than I thought, or a combination of the way I set my phone up, by deleting lots of .apk's, and using Greenify and Droidwall ?

Now 3 full days with the phone, each night after 15 hours off the charger, I still have 35% to 40% battery left, and typically used 3.5h On Screen time at that point. And majority of it on the 4G network, just a few hours out of 15 on WiFi.
I am shocked getting this kind of battery life, totally unexpected.

Thanks for the feedback!

I would say this is pretty good battery life . I should be able to get 5.5h to 6h On Screen time on this phone. That's nearly 50% better than my Nexus 4. No way I would trade this phone in for the Nexus 5 only having a fixed 2,300mAh battery.
Only other phone coming out I would upgrade to is the Galaxy S5 due out in 4 months in February, with metal body like the HTC One and iPhone...the next gen Snapdragon 1,000 processor...a 2,800-3,000mAh battery...4GB RAM...all new screen technology, no longer AMOLED...and redesigned Touchwiz, based off Android 4.4 Kit Kat.
I was on the 4G LTE network majority of the time, only on WiFi a few hours.

that's Pretty good battery life I must say myself,but by turning off all those features you're defeating the whole purpose
of having a smartphone. with all those features not being usable you might as well own a razer flip phone
I have bt,location,and all those fun gadgets on and still get a good 12 hrs up time and I use my phone too
I'd like to know what you get with your phone loaded up with all the features enabled,thanks

I just swapped batteries after 51 hours. Over 3 hours of screen time, 90% of which was while using LTE. Other than that there was about 10 hours of LTE standby, 2.5 hours of Airplane mode and the rest WIFI. I use Greenify like the OP, but I use Tasker to enable Bluetooth and GPS when I leave my house and disable it when I return home. I leave my brightness on auto and sync on.
When I was connected to WIFI at home I would get crushed by WIFI related wakelocks, but using a network logger I was able to eliminate the causes, most of them were related to my iMac constantly sending out random packets to everything on my network. Other than that I found Google Now was a huge cause of background web traffic, while still keeping location services on, I turned off location history and reporting in Google Now and that cut down drastically on the amount of background web traffic Google Now uses, but I can still use Google Now for what I need it for. I also found apps that have no reason to access the internet like GSam Battery monitor among others were doing so. With a combination of Greenify and removing internet access permission using App Settings (Xposed framework module) I was able to get those under control.
All this was a lot of trial and error, and it took me a while I figure out a good combination of conditions and applications to use to control the amount of background web traffic (causing WIFI related wakelocks). But now I get great battery life and really no loss of functionality. I think Google needs to do a better job of policing developers when it comes to this sort of stuff, the average person isn't going to go through all this.
Side note, has anyone else notices that at around 40% the battery tends to drop a bit more rapidly than the preceding 60%? If I was able to get 3 hours screen on time over the first 50% I'll probably on get 2 hours on the next last 50%. Its clear as day when you graph battery life vs screen on time after 40%. I have 2 official Samsung batteries I use and it happens on both.

I was on my S4 pretty hard today, all day and night long, surfing the web, reading XDA, watching YouTube, sending tons of texts, keeping up with the sports scores on my favorite teams playing today, using Sportstacular a lot.
I think almost 6h On Screen time is really good, and blows away my Nexus 4, which was getting around 3.5h to 4h On Screen time. Wonder how well the Nexus 5 will do On Screen time when hammering on the phone all day and night ?
