Is Battery life really short?

Hi Everybody,
I am using my HD2 since 2months and I share with you the general Idea that Battery life of 1-2 days is not enough for a device with the ambition to serve as phone as well.
I am using the device for professional activities: document sharing, webcalendars, emails on the go... but with an internet access not contiguous, since I only want my mobile to donwload mails when I
am not at home or in my office (were I have more professional stuffs
for that).
So, I installed the WMLongLife to Switch off communication interfaces whenever not used.
However, during last couple of weeks it happen to me to work prevalently at home and in my office, without the requirement to use the network from my HD2.
Accidentally I noticed that if I charge the HD2 and never use internet services (but only as a phone: 5-10 calls per day), the battery life magically goes from 1-2 days to 1 Week and more.
Is it normal? Maybe some device is not properly shut down after first use?
Now I charged my mobile on thrsday morning, and after 5 days of use I have still 42% left.
I wish to share your opinion, and to know if there is outside a better software than WMLongLife to preserve batteries when high speed connections, BT and Wifi are not used.
Thanks a lot

It's a phone with a massive screen, bluetooth, wifi, 3G and the list could go on...
I myself, is amazed that it can last a day.
Using it with constant 3G, bluetooth, GPS back and forth at least once a day, e-mails ticking in all the time, bluetooth headset and so forth...
The HD2 is like a small laptop...
- try getting a laptop run a full day on a battery the size of the HD2s.

1 week and more? Wow....

I fully charged the phone last night around 12AM, now after 13 hours most of which is standby, 1 hour of music, and maybe 30 minutes of browsing/playing with it its at 70% battery life. Is this normal?
I dont get 3G and I have wifi and bt off. Any other ideas to conserve battery?

The HD2 is as good, if not better than any other smartphone I've owned. I always recharge my phone overnight, so as long as the battery's good for a day I'm happy. Any bigger battery and the phone would need to be much fatter to accommodate it.
A week sounds pretty optimistic to me.

You could try and turn down the brightness of the screen for one...
I had mine on 100% for the first couple of days, but it just ate the battery like that. Then changed it to 70% (almost can't see the difference) when it's on battery, and that helped a lot!
Then you should perhaps try and download BsBTweaks or something like that, and activate the "power save" option...
Something to do with the SD card or something, not sure...!?
But to be honest, I think it's pretty decent.
13 hours of stand by, 1 hour of playing music and 30 minutes browsing/gaming - and still on 70%.
You have to remember, it's a very powerful device and as such it uses a lot of power!

Again I confirm,
charge this morning is still 25% left and yesterday I used internet connection for 15 minutes, then switch off devices and a soft reset to stop eventually pending drivers.
I do not use HD2 for listening music or playing films: only calls, contacts, synchronized agenda with gcalendar, emails, and internet.
Previously I noticed that after using even once the internet connection (without the soft reset), battery last at most 36 hours.
That is why I suspect some processes/services be pending in background and draining battery low.

Again I am not trying to demonstrate the life of my mobile is longer...
... Just noticed that there are some operational conditions that may prevent higher power drains and to understand if someone else has investigated the point.

I do the same!
Check email one or twice a day. 5/6 calls a day. Wmlong life on. Don't care about 3g... it's set to be in automatic. Some excel and word files. Some sms. It's incredible that such a powerful device can stand by so long!
Otherwise when I use it for work, wi-fi, bluetooth, gps and bla bla, the life of the battery is about 12 hours... but who cares?

9% this morning but still alive with phone interface working...
Do it exists for WM6.5 an extended taskmanager (AKA in the windows style) that can also reports for processes and spent CPU time?

I can barely go a full day and have to charge it at night.
Is anyone else getting really poor battery life? I have Wi-Fi on a lot but with screen off just so it automatically gets my push e-mails. Could this be the reason?

Poor Battery Performance

I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help

I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.

Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.

no need to worry more

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.

since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322

so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.

it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.

I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).

My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.

im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.

[Q] Battery drain issue?

Hey everyone,
I'm not sure if I have an issue with a defective Captivate or if it running as intended. That's why I've come to you guys for some insight.
Here's my scenario:
A few days ago, I decided to leave my Captivate off of the charger overnight to see how much battery I would awaken with. It was just a little experiment I thought of to see how much the battery drains while not having anything intensive to do (such as power a screen). I fully charged the Captivate to 100% before setting it on my desk and going to bed. As normally, everything was turned off except wi-fi. When I awoken the next day (8 hours of sleeping), to my surprise, my battery was down to 27%. I was shocked that something could have drained almost 70% of my battery overnight. I downloaded an app called Spare Parts as a recommendation by some people and I seen "Running 100%" which means that the phone spent no time sleeping. When I look at any partial wakelocks, it showed "Android System" as a full bar. I assume that it could be a bad app that was keeping my phone from sleeping.
I restarted the phone, battery pulled, charged up and uninstalled some apps. Everything seemed back to normal as when I checked the the running %, it was proportionate to how often I was using the phone (not at 100%). I specifically checked if the phone was sleeping and it was through some monitoring. I would use the phone for 1 minute and then let it sleep for 2 minutes and you could see that the running % went down, as it is suppose to.
I kept monitoring the running % over the course of the day and it was fine. The less I used it, the lower the % would go; the more I used it, the higher. I also monitored what kind of apps I was firing up and I specifically made it an effort to not open any apps that were out of the ordinary. If I did, I checked to see if it kept my phone from sleeping and it did not (through my same usage tests as above). However, even after my close monitoring, sometime during that day, my phone would stop sleeping once again. I could tell because my running % never lowered, no matter how long I didn't use my phone. It would keep climbing which means it no longer slept. I made sure that I didn't do anything out of the ordinary too as I used the same apps as I did when the phone was sleeping fine. I checked "Android System" and it was getting larger. The battery was around 80%.
I charged up the phone again to max and made sure that nothing was preventing my phone from sleeping. Did the tests again and running % was proportionate again and I double and tripled checked to make sure the phone slept. I then left the phone not charging again to see what would happen as I would have no interactions with the phone to open any apps or change any settings. To my surprise, my battery was down to 60% (~ 6 hours of sleeping) when I awoke. I checked the running % immediately in the morning and it was at a very high percentage. "Android System", once again, dominated the partial wakelock portion.
So what's going on here? It doesn't actually seem like I'm doing anything on the user end to prevent the phone from sleeping. How come it decides to act up all of a sudden? If it was a bad app, how come it decides to prevent sleeping all of a sudden and not before? Even if it was a bad app, I didn't even launch anything while sleeping. Does the phone decide all of a sudden to stop sleeping?
The apps I use are:
Tasker
Y5 Battery Saver
Launcher Pro Plus
Twitter
SwiftKey
NHL Gamecenter
Handcent SMS
doubleTwist
Dropbox
Does anyone have the same problem?
Any help is appreciated.

Get rid of any task killers and battery savers they do more harm then good and most developers recommend not using them, they cause battery drain. The only battery app I use is Juicedefender because it keeps the phone from connecting constantly and keeps apps from running in the backround. I set it to connect every 15 min for 1 minute to sync, I turned off all notifications because they annoy me and I don't need to be notified everytime I get an e-mail or someone posts on Twitter or FB. My battery life has improved greatly once I dumped task killer. Also, I am running a Froyo mod and my battery is amazing now and my GPS works.
If you are in an area with a weak signal this will kill your battery because your phone is constantly searching for a signal and trying to connect. Also turn off wifi if you are not near wifi this will save battery.
Also try calibrating your battery and bump charge it. Here is a link for that. http://forum.xda-developers.com/showthread.php?t=765656
The battery will improve, mine got better after a few weeks of break in. I am at 60% been unplugged since 10 am and I made plenty of calls, checked e-mails, sent e-mails, checked XDA developement all day and I have plenty of juice.

Good infos. O agree with not using task killer

Hmm, thanks for the tips but there still seems to be something lingering around in my system that doesn't allow the phone to sleep. It seems to activate all of a sudden as well without user intervention.
I again left it overnight and it drained again when I woke up. I lose significant battery overnight when I sleep. I'm thinking about just restoring to factory settings. I've only had the phone for a week so I wouldn't lose that much data. I'll monitor it from the onset once I factory reset it and see if it's a hardware defect or something that was bad in my phone.

Do you have a live wallpaper installed? Also, do you have a bunch of Widgets on your homescreen? Are you constantly synching with e mail, FB, etc? No doubt something is running all night. It's not the phone, it's something you have installed. I set mine to sleep with Juice defender at night so nothing syncs. Check your wireless bill to see how much data is being sent while you sleep. Why not charge your phone while you sleep?
Sent from my GT-I9000 using XDA App

Nope, no live wallpapers and the only widgets I have on my home screen are the LauncherPro Plus widgets, Smooth Calendar and BattStatt. The only syncing I have going on is Google Calendar and Gmail but both of those shouldn't cause the phone to not sleep.
I was thinking of using Juice Defender but I would rather just get to the root of whatever app is preventing my phone from sleeping and kill it at the root instead of finding workarounds. For all I know, my phone may not be sleeping not just overnight, but with normal use as well and it would adversely affect battery life throughout daily use. I need the piece of mind that my phone is properly sleeping.
And I have no issues with charging while I sleep, but again, I need to find the root cause. If for whatever reason I'm can't access a charger overnight in the future (such as if I sleep over at my gf's house), I want to know that I won't wake up with a dead battery in the morning.
I really appreciate the help though.
As for what I decided to do next, I actually factory restored my phone yesterday morning and so far it is working well. I did not download any apps at all to make sure that this problem didn't persist with a stock phone. If it did, I would know that it's a phone defect and not something I did. Throughout the next week, I'll be installing different apps one by one to see any one of those apps will cause my phone to not sleep. This will allow me to isolate the app. It's long and tedious, but I would go through it for better battery life. So far, it's been working as I'm already through 10 hours on my phone with moderate use and it's only at 50%. Whatever was destroying my battery before absolutely had an effect on my daily battery life as I would struggle to even get 10 hours on my phone with moderate use.

Same Here
I find your post very interesting. I have not yet used Juice defender, however, I am now more keen to battery drainage. I talked on the phone for about an hour the other day and my battery went from 100% to 40%. I find this unacceptable for a phone. Imagine taking conf. calls and conducting business in the field throughout the day. My battery would be dead in two hours without checking email
I hope you can reveal your findings to help us all.

JROCK

Battery problem fixed using the simple technique similar to the one shared back in this thread.
I used to lose 10% per hour (or there abouts) and by 5 or 6pm needed to go on charger. At the very best with no use it dropped 3-5% in an hour.
Now its all changed...
After being off the charger for 35 min and taken 2 calls and sent a couple of txts she still read 100%.
At 5hrs 17min off the charger it is at 81% and there has been 6 calls in total and about 9 txts, plus a couple of appointments added.
Here is what they said to do and it worked...
1. Charge the phone for 8 hours, but make sure it is turned on while charging.
2. Unplug the phone, turn it off, plug it back in for 1 hour.
3. Unplug it, turn it back on for 2 minutes, then plug it back in for 1 hr.
Then unplug and enjoy the new battery life
Sounds too easy to work, but bugger me, it did!

27% is clearly abnormal.
Sometimes, I put the phone on it's charger after a pull day only using 27%.
I read somewhere on XDA that some early phones had defective screens that would only shut the backlight off and not turn off completely. Don't remember what came of that thread though.

I have a battery drain issue as well. My Captivate is 2 days old and been charging it every night. The first charge was done via the computer while transferring music over. After moderate usage (1 hour of music, browsing apps, learning how to use the phone, etc.), the battery died after 10 hours. GPS, and bluetooth was turned off. WiFi was used for maybe 20 minutes. When I got home, I charged it overnight for around 10 hours.
Today, the phone died on me after 9 hours. I rooted via z4root and applied RyanZa's latest OneClickLagFix, which both apps can be found on the market. Before that time, the battery said there was about 80% remaining. Fast forward to 6 hours later and the battery is gone. Again, moderate usage.
According to *#*#4636#*#*, my Screen On is at around 60%. A few other bars are pretty high as well, but I'm not sure how to do a screenshot on the Captivate right now. The only method I found requires using a PC. Plus, my battery is dead meaning I have to charge it overnight again.

I had an issue for the last couple of days, just figured it out earlier today. I had a corrupt thumbnail file on the external SD so my android.process.media (something like that) was constantly running.
I first realized something was wrong before I determined the battery life was bad when I noticed that my CPU was constantly at 11470-1200mhz or 975-1000 when I disabled the OC.
Unmounting the card would allow the CPU to drop to under 200 at idle so I knew it had something to do with the external SD. Turned out there was a bad file under a DCIM (camera folder), so after I deleted it, it became smooth as silk!
Of course it's still an i9000 rom so battery life is still questionable

Sorry for the hijack!

Here are yesterday's results:
Does these results look normal to you? I'm particularly concerned about the Social Hub and screen, and running. They're all higher than I expected. The brightness of the screen is set pretty low, maybe 2/10 of the brightness bar. As for Social Hub, well all I got is the Facebook widget, which is set to sync every 4 hours. Other kinds of syncing is off. GPS is off too. I don't have any battery saving type of apps yet, except for RyanZa's OCLF which includes the WiFi timeout.
I ended up charging the phone at 5% battery left. I had to sleep!

[Q] Am I the only one getting good battery life on this phone?

Before I bought the Vivid, I read every review that was out, even the customer reviews on AT&T's site. There was a common theme in all of them: Battery life is bad. Even the glowing reviews had "battery life" as a con or said they wished it was better.
Needless to say, my expectations weren't high. I have had HTC phones in the past and battery has never been their strong suit.
Imaging my surprise when I tell you that after a 10 hour work day, I go home with an average of 60% battery. I text throughout the day, have seven e-mail accounts syncing, widgets that pull data on my home screen, etc. I am definitely using the phone. I leave Wifi on all the time and I have LTE access wherever I go, so the LTE radio is always on.
Am I really that unique? Is anyone else getting good battery life with the Vivid? If the Skyrocket is supposed to have way better battery life, I can't imagine how long it would last compared to my Vivid, at least with my use.
Overall, very happy with this phone. Battery life is what always drove me away from Android and that is not an issue here.

I would say I unplug my phone around 7 and it gets to 10% around 7 so 12 hours ? I would say thats pretty good battery life I came from the inspire and it would die after 7-10 hours so I would say its a lot better! Though I cant wait for a cm9 or 7 rom since i was getting a full 24 hours + With that.... So im very excited to see!

I am also getting about 10 hours with heavy texting use throughout the day. I have friends overseas and we text via Whatsapp and sometimes Skype. Otherwise it would last even longer since I the screen display wouldn't always be on. I am not complaining getting 10 hours of use though since I'm coming from an HTC Aria which was about half that.

Almost as good
With the standard battery that came with the Vivid, I am getting 24-48 hours on a charge, but I don't use it as much as described above. I have WiFi on at work, but I don't do a lot of e-mailing from the phone. (I work at a desk all day, so I have e-mail on my PC.) But I do look up a lot of things. I suspect I use the phone for at least a few minutes 6-8 times during the work day and 2-3 times in the evening (with WiFi at home). I am not a heavy data plan user, partly because of WiFi access. I use Bluetooth to connect to my car's sound system during my 30-minute commutes. I usually put it into Airplane mode at night, cutting down on the battery consumption. So, I would expect to get somewhat better battery usage than someone who is on their phone much of the time.

Just out of curiosity: Why put it in airplane mode at night? Why not just plug it in to recharge?
I have a lot of days like you where I use it lightly. I have noticed that the idle drain on this phone isn't nearly as bad as past Android phones I have owned.

Yesterday I got 16 hours out of my phone. That is with me syncing three email accounts, running a live background, using data to read news articles, downloads from the android store, browsing the web, and making around 30 minutes of calls. It is much better than my cappy was. I made sure to charge the battery when I first got it all of the way before powering it on. I also have let it run down completely to cycle the battery.

When my phone was stock the battery life was OK, not terrible, but not great either. With a custom ROM the battery life has increased greatly. I unplug it around 8am and when I go to charge it at night I usually have around 40% left. That is with moderate to heavy use, at least that's what I consider my use.

Failed to mention I am on the stock Rom.

I'm always getting 20+ hrs on my vivid with med. Use with the stock Rom my battery was pretty good but with rumraider its going on about 30 hrs with 40% left ....wow and I haven't even charged it since I flashed

I think alot of the differences in battery life have to do with how strong of a cell signal you have. The weaker the signal, the quicker the battery dies since your phone is constantly trying to stay connected. Also, if your signal is bad, than that usually means your internet data is slower too and thus it takes longer to download news, email, and web pages, thus killing your battery even further.
Although, my signal is usually at 2-3 bars, the battery seems to last much longer than I was led to believe from reading reviews. Overall, I am pretty happy with this phone.

Just a suggestion, I am getting fairly good battery left, I am on a rooted stock rom with most of the bloat ware & processes frozen thru Ti Backup, I have wifi on all day but limit sync schedule (with refresh on use enabled) I have noticed that the battery stays at 100% for a while then starts to drop off. Today running about 7.5 hours and currently have 95% charge available. I also have Juice Defender free helping out with ballanced profile enabled.

Simple rundown:
I text fairly frequently, do a reasonable amount of web browsing (read: where I don't have access to a computer), sync 3 email accounts, check XDA and play GameBoy on the thing. Weather is on hourly autoupdate with location; news is on demand when the widget is viewed.
The only daytime charging I do is when I'm using my phone as my car's AUX input, where it is plugged on the charger (although still draining according to the battery graph).
I end the day with 52% battery life, off the charger at 7:45 AM, back on at 12:00 AM. Much better than my Captivate. Prior to root, custom ROMs and SetCPU, it would clock in at around 38%.

I think alot of the differences in battery life have to do with how strong of a cell signal you have. The weaker the signal, the quicker the battery dies since your phone is constantly trying to stay connected. Also, if your signal is bad, than that usually means your internet data is slower too and thus it takes longer to download news, email, and web pages, thus killing your battery even further.
Although, my signal is usually at 2-3 bars, the battery seems to last much longer than I was led to believe from reading reviews. Overall, I am pretty happy with this phone.

I totally agree with this. My office is in the basement of our building and I get fairly poor signal - maybe 1 bar but I still can access the LTE network. When I turn my wifi on, by the end of the work day, my battery is much less drained vs not having it on and my phone searching for signal from the mobile data network.
At home, I have a pretty good signal, but there's not LTE coverage yet, so the battery does last longer throughout the day.
Even on the bad days I would get home and keep it running until I plug it in before I go to bed, so that's an average of about 17 hours in total per day that it's running on battery and on average I'd have like 30-40% battery left.

I was using an iPhone 4s before I bought the Vivid and I used to go home with about the same amount of battery after a full work day. Granted, the 4s gets worse battery life than the 4 by far, but I still think it's impressive that an Android phone, especially an HTC does this well and it makes me wonder why all of these people in the reviews have been getting such bad battery life.

It all depends on what it's relative to. When I had a BB, I'd go almost 5 days between charges, but there's no comparison between a BB and a 4.5" LCD screen.

This is a key point. The big screen is a huge battery sink. The battery widget in Beautiful Widgets gives a percentage battery use for components. With mine, the display's battery usage is always at least twice as big the next nearest battery sink. It is not uncommon to see that it is using 90% of the juice. I think this explains a lot of the early complaints about battery life. We all spend hours playing with a new phone and getting it set up to our liking. That means the display is lit up for hours. That means people get lousy battery life when they first get their phone.

Just out of curiosity: Why put it in airplane mode at night? Why not just plug it in to recharge?

I was trying to see how long I could go on a single charge. Airplane mode shut down radios that might otherwise continue to run, trying to pull data I would not see while asleep. Also, I would occasionally run the battery all the way down before recharging. I generally plug it in at work, in my car or at home when it gets down around 10% remaining.

Battery Life

I can't believe how incredible the battery life is on my Sprint Note 4. To give you a real world example of what I'm talking about...I'm a ups guy and stream Sirius over my phone to my wireless boombox all day while I'm delivering. My previous android phone on a full charge would get me to about 1PM before needing to charge the phone from this streaming.
With my Note 4 today I started streaming sirius at about 8:30am this morning and streamed it non stop all day for 10 hours. While streaming I also browsed the internet on lunch for about 40 minutes of screen on time for that. I then made about 40 minutes of phone calls after work on the way home. After all of that...I still have 60% battery life left without any charging today.
Man I love this phone!

tried ultra battery saver mode for the first few days and made it from 100% to 25% in 2 days and 4 hours with ultra on and off. then played a game for about 7 hours and it drained my battery 50%. Damn impressive

Not sure what to make of mine, I lost 10% in an hour, most of that was when I was driving!
Hmmm, but then I do seem to have a lag issue like others seem to be having too?

It's either something you have installed or how you have your preferences set. I turn off wifi & gps except when I'm using them (both for battery and privacy purposes).

Reloead some screenshots of the battery for more info and in better quality because I can't see this one.

I simply can't agree more dude the batt life on this beast is simply incredible I'm averaging around 13-15hours off charge with 6-7hours On Screen, take note (pun intended ) that when I put it on charge when I go to bed I still have well over 25% battery remaining, its simply incredible, even for us heavy users.

Must have a lemon
I have had my phone for about 3 days and I charge it to 100% before going to bed. When I wake up the battery life has dropped all the way into the 60s. before this phone I had a note 2 and this is way worse than it was. Screen was obviously off all night. Any suggestions appreciated!

It all depends on what you have running in the background. Push notifications? I've frozen all bloatware and turned off push. Is your wifi on maybe? gps? I leave mine unplugged all night (12 hours) and it goes down 3%

Did you install anything special like Greenify? Did you use any of the extra battery saving modes? What is your screen brightness set to?
I think the Sprint version is the Snapdragon, not Exynos, right?

I absolutely loved my Note 2 battery life, but this Note 4 battery life surpasses my Note 2 by a fair margin. I am one happy camper.
Edit: Sprint SD version.

I'm getting less battery life than I expected with my Exynos note 4. I just got out of bed and unplugged it , and used it for about 15 mins to browse tapatalk and email and etc. And in that 15 mins I lost 5% .

I also noticed a high Android System in my usage. Any thoughts on what could be causing this?

This is screen cap.

Mine today

Im only plugging in now at 24% because im going to bed.... actually i have a second battery i might let it run overnight

Pretty good

If you have battery issues, make sure you are not syncing to drop box or google photo back up all times. For example, I use photos to back up all my photos but in the settings I have it only back up when plugged in to the charger. Hopefully this might help someone.

Nothing special installed for battery life and not using the power saving modes. I keep the screen set to auto brightness when at work, but put it on max brightness at home on the weekends when I know I have chargers available because I love the nice bright display. Yes, I have Sprint which has the Snapdragon 805.
I turn off GPS & Wifi when I'm working for battery saving & privacy purposes, but leave bluetooth on all day. I don't have my microsoft email auto synced, but have gmail pushed.
Here are the results from today (attached). Still well over half a battery left after midnight.

To all the people with battery woes-
Pause your pedometer in s health and remove pedometer from lock screen(of course if you don't use it much). It saves a hell lot of battery. It did at least on my SD805 note 4.. I am a heavy user with 3g on all day but never run out of juice. Screen on time averages 7-8 hours daily with browsing/playing games/chatting. I have wifi, synch and gps off when i am not using them.
And yeah i charge every morning, but have never seen my battery less than 39% when i charge lol. This beast is incredible. *super satisfied*
