So I think I have read that it is not good for the battery to leave it plugged in on a full charge. Last night I went to bed at 3 am on a 30% charged battery. I THOUGHT it was at 50% when I went to bed but looking at juice plotter I was wrong. At 8 am, according to juice plotter, the phone died. I missed my alarm and was late to work (my new job I have had for 2 weeks btw...doh!).
The screen was off and I have setCPU to underclock the CPU to 400 max 200 min when the screen is off. With the screen on and battery set to <80% the phone is underclocked to 800 max and 400 min. Basically the only time I have the CPU set to 1000 mhz is when it is plugged in.
Anywho, my question is this: Can I keep my phone plugged in while I am sleeping to insure this doesnt happen again without killing the longevity and usefulness of the battery? I know this time was mostly my fault with the battery being at only 30% when I went to bed, but I am trying to find a good balance between optimizing the battery and making sure this doesnt happen again.
Its how i charge mine every night for a month now. And no issues.
Have you paid for Juice Defender? If not i'd recommend it. I've spent the massive $4 for this app and like the rest of the customization for the power configuration. I used to leave my captivate on the charger all night but I don't anymore.. Not sure why your phone died on you, how do you have Juice Defender configured?
With a low battery level, you should charge your phone for anywhere from 8-12 hours. Battery indications are generally always incorrect. When your phone says it is at 100% after a few hours, that is incorrect. That is generally how it is for all electronics.
SetCPU has known issues with all SGS phones, Captivate included.
I had my phone depleted to 10 to 15% quite a few times now and I had no problem with charging. And I always leave my phone plugged in whenever I'm home.
You should be fine leaving the phone plugged in. The smart part of the charger is in the phone. You will get repeated charge complete notifications i think.

I have the free one. I must not know what exactly it does. I thought it just plots what the battery is doing?

What's the benifit of the setCPU other than crash your phone ?
The biggest battery hog is always the screen display. If you're running stock JF6 ROM, it is well over 60% of the battery usage. Newer firmware does a better job controlling the screen brightness but still amount to 50% of the battery usage. The second biggest battery hog is 3G data transfer (or wifi data transfer if you primarily use wifi).
The saving from underclock the CPU will not be that much, IMO, other than make your phone feel slow I guess.

I permanently underclock to 800 mhz when using battery power. It still seems quite snappy to me.
If it is known to crash the SGS a lot, I will take it off. Guess I need to do some more research.
Any tips on how to handle the display?
Either flash to the newer beta firmware JH2/JH3 or manually dim the screen down. The automatic setting doesn't work well in JF6 firmware.

SetCPU is used to overclock, underclock, set different CPU throttling profiles. I don't think running setcpu is going to effect how fast your system is by running in the background, it uses like zero cpu cycles. My set up is currently the hybrid rom, setcpu oc to 100 to1.2 interactive and with the screen off 100 to 600 conservative. Ultimate juice defender set to turn wifi and 3g on only when certain apps are running that I picked, along with being one 1 min every 15. I'm getting about 36 hours a charge with average use, and I use about 1% an hour to every 2 hours in standby. My little juice defender score thing hovers around 2.33.
Setcpu does have good advantages, just learn how to set it.
I didn't mean setCPU itself use much CPU cycles, but rather by manually underclock the CPU to slow it down.
I see in your setup, you turn off the 3G data hence get better battery life. Unfortunately, it doesn't work for me. As I have 3 push email accounts: one Gmail, two Exchange Accounts which requires constant 3G connection.
If you leave the Juice Defender off, how much extra battery life do you get by under clock your CPU? One post I read that states once he removed SetCPU, his battery life actually improves.
Do you guys use JuiceDefender as an alternative to a Task Killer or side along with it? and does it work well with the captivate?
I keep myself plugged all night ALL the time and I'm also constantly on the phone from at least 12AM to 4AM while plugged in during that time. Haven't had problems so far.

Im patiently waiting for an official update. If it doesnt come by the end of my 30 days (which is 28 days away) at ATT, back the phone will go.
maybe something wrong with radio rom? (or how it is called)
If your phone stays in weak signal area a lot, that could kill your battery quick as well.

Yeah that happens to me, happened on my iPhones as well. My signal constantly switches between no signal, gprs, edge and 3G, it is never consistent and the searching just kills battery life. AT&T have been getting deluged with reports via the AT&T Mark the Spot app so hopefully they address the gap in coverage here soon!
Semi on-topic question. Is there a way to test battery health? I used to be able to get 36 hours on a single charge, and my phone was loaded with a ton of widgets and crap. Now I am lucky to get 12 hours and I have zero widgets, wifi always on, and a black lockscreen/background. Also running stock free juice defender.
Also, does anyone have an issue where they unplug their phone, and its already at 99% even after a full night of charging?

Okay, a little back story. I've been a BB user for quite some time now, got bored and made the switch to N1 this past January.
At this point I'm ready to say: The N1 power consumption or battery BLOWS CHUNKS. But folks thats my take.
I mean here I am with the most powerful and best phone in the world right now and I have to keep my brightness at 33% (GOD forbid I forget and keep it at 100%, I wont make it through the day!). I have to keep my GPS off (so my geo tagging is always off by a few thousand freaking meters). I have to limit my use and take it easy on data intensive apps. It's ludicrous, I want to use this damn thing.
Don't get me wrong I'm fine with the 33% brightness and with the light use (because I'm a student and quite frankly I don't really push the phone like that, due to being in class). But I would still like it if the phone wasn't CRYING for the "milk" bottle every day sharply/promptly at 8 pm.
So the phone makes it through the day (hurrah). But it still annoys me that now I have this new "nag": "get home and charge me Ori". So if anything spontaneous pops up like say: a date with a nice young lady, you can bet your bottom dollar my phone won't be making it alive that night. It's another constraint on an already constrained enough life.
My buddy says "dude I don't know whats wrong with your idiot self.. blah blah blah.. my Nexus battery is great". But the damn jerk is coming from a G1 !!! go figure LOL...
When evaluating something you don't compare it to a pitiful performance. You see how you stack up against the best. So if you reached your conclusion because you are comparing it to a G1 or Cliq I have to honestly disagree with your method of reaching that conclusion.
PS. I'm not a nagging *****. I know I came off a BB. Thats why I'm not asking for much. I would just like to see the phone consistently make it to 11 PM every night from a 7AM 100% charge. Is that too much to ask for?
my battery never dips below 50%... of course i'm working most of the day instead of playing with my phone.
Seems about the same as my Nokia N95's was to be honest.
try the undervolted kernel, it saves you quite a bit of juice.
ill toss my input in on this after i run the att one for a few days to see how much running strictly on 2g actually saves, the tmo band one i had last a good 12-14 hours if i was playing with it mildly at work. thats with the check mark for 2g only, wireless is usually constantly on, and gps always on(but not always running up in the status bar), brightness set to auto
Not sure if there's whole lot you can do if you want to keep brightness at 100% and GPS chip on all the time.
I hike quite a bit and I use SportyPal to track my progress. Obviously when I hike, the screen is off but GPS chip is always on. Although I never managed to completely drain the battery so far, I would say it will last around 7-8 hours. I do use SetCPU so that when battery reaches below 40%, clock goes way down to the minimum possible.
Other than getting an extended battery, not sure if there is a solution. 100% screen brightness and GPS really taxes batteries on all cell phones.
By the way, this is MUCH MUCH better than HTC Magic (which in turn was much better than HTC Diamond). I'm not sure how they did it since the battery capacity is the same, screen is larger, and CPU is faster. I am happy.
Battery is better than the last few HTC devices I've used and on par with the TP2 (all had similar features, large touch screen, Wifi, GPS, BT). So I would say it's about par for the course as far as I am concerned.
Try the 3200mah battery from Seido... you can run all day with wifi, gps, and bluetooth plus have screen at 100% and still have 50%+ battery at 8pm.
If battery life is more important than the slim look, get the sedio 3200mAh battery.
With 0% brightness, occasional use (GMail, GVoice, GTalk), GPS and Sync on, about 20 minutes of talking, meebo IM running... The battery just lasts 12 hours. CPU profile set to 512MHz when below 50% battery; and is fixed at 245MHz when in standby/sleep.
For the amount of things that it can do I'm happy with the battery life.
If I'm going out I carry the AC cable in my coat pocket
I realize this may not be the best solution for most of you, but I also have a portable Duracell charger. It normally acts as a charger for 4 AA batteries. But I can plug-in a USB cable on the charger and the other end to N1. It gives me roughly another 2000mah worth of juice using 4 Eneloops. The charger is bulky though so no good if you want to carry them in pockets. But works for me when I carry a backpack with me. I needed this charger anyways for AA batteries so it's a nice bonus that it can provide some mobile juice for N1.
My battery life is pretty great. I'm running the latest Cyan with the EPE54B radio, i keep the screen on about 75% brightness and never change it, I leave wifi and gps on always, I have bluetooth on and connected for about 2 hours a day, for the 8 hours I'm at work I don't use my phone much only to send some txts and maybe use a couple apps. So I unplug my phone at 7am and when I leave work at 5pm I have 82% battery left everyday with my normal usage.
Just for reference; before switching to Cyan and the latest radio i would have 75% battery when I left work.
What are you people doing with your phones that you have to carry a charger or a spare battery with you?!
I'm coming from a HD2 and I easily get better battery life than half you guys even with heavy streaming radio/youtube usage and that thing has an enormous power-sucking screen!

Thread revival time !!!
OK so I discovered a few things that are worthy of mentioning since I last posted this issue.
My Nexus off/wake button crapped out and I sent it back for repair. When I got it back it was wiped (like new). I forgot to setup my facebook app and widget. For about 2 days I was going around with the facebook app "off" (it was finals week as such I was not paying much attention to facebook or distractions). I noticed better battery performance. Eventually I set it up but my "Sync Contacts" setting is set to "Don't Sync".
Also I got the SMODA widget that gives u direct "on-off" 3G capability. So whenever I'm at around 30% battery life I throttle the connection to squeeze out as much life as I can. Unless I'm browsing and I need 3G.
Good day to you all and enjoy the world cup.
In all honesty, I've been getting the best battery life I've ever had with Froyo. I only charge my phone in the car with the car dock to and from work (25 minute commute) and occassionally let it sit on the desk dock when I'm messing around online. With those charging habits, I typically get two days of use out of it and have no issues doing any of the things I need to do with it without a charger (games, navigation, calls, texts, web+market browsing, etc.). I could not say the same about any of the Cyanogen ROM's I was running before.
Hope that helps.
I have to admit...I am a bit bummed about the battery life. I have the stocked 2.1, on the ATT N1. I have turned off the brightness and I can get 3/4 of the day on the battery. I thought it would last all day but I definitely have to charge it by end of day.
I am looking forward to Froyo for, by all accounts, the battery life has been improved.
Again, I should emphasize that "I'm a BIT bummed" for all in all...I'm still loving my N1 and haven't looked back.
I've got Froyo on mine and this is what I've noticed.
If I turn my phone on, and send about 10 text messages in an hour, then turn it off, my battery life will be around: 94%.
If I let it idle for an hour without any action, my battery will drain about 1%/hr.
If I am using the internet and sms and just constantly using the processor on the phone, in abour an hr I'll be at 85% battery.
This is all with the backlight set at 11% (lowest setting it will go)
my battery last 27 hours on reg use... 17 hours on heavey use...
Pauls Froyo
3200 Bat
GPS always on
Brightness Auto
Listening to music alot on it to.
I find that on the ATT nexus one, setting to gsm auto (prl) makes a tremendous difference for idle time. With this setting I lost only 11 % in 12 hours of idle. And when I unplug, after 1 hour my battery will still be at 100% with no use.
This setting still gives you 3g too, so no worries.
My N1 on froyo started to hog alot of juice. I don't know why, it was fine the first 2 weeks but after that it started to suck up loads for some reason. Got tired of trying new kernels and i did many options so i gave up and went back to Cyanogen.. Running 5.0.8 Test5 with Froyo Kernel and it's about 20-24 hours since i last hooked it off the charger and it's at 56% left. Amazing. Tho' im a light user and i keep most stuff off when i don't use it. Even 3G.
I think that our perception of what we should get concerning battery life is a bit skewed. If I have RIM device (last was BB on metroPCS) I can go like two days without charing. All my email is push. There is no Facebook widget, or weather widget, etc constantly updating. The screen is half the size with weak resolution. The processor is half the speed, or less. The ram is barely enough to run the device. I could go on and on.
The fact is you have a computer, a small computer you can carry in your pocket. This machine is about as powerful as a desktop was 2 years ago. You are powering it with battery that is 1500mh and is the size of a dollar bill folded in half. What do you want exactly?
If you want a battery that lasts 2 or three days, get a dumb phone. If want a pocked PC, you are going to have to deal with the fact that doing all of the things your phone does uses battery power.
If I unplug my laptop I get 2hours and 15minutes. My phone lasts about 7-8hours. I stream music an hour or two, text, play some games, browse the web. I know that it is going to die. I have a spare battery. I change it if I can't charge it.
Battery life is worse than a Blackberry and better than iPhone, and you get the fastest device on the market. What more could you ask for?
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.

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.
We in the field in the army have no place to recharge the battery, so i have a second spare. After the first battery out, second battery i should calibrate or simply change it? Milestone generally maded to hot replace the battery? Second question: The battery is terribly wasted when data using. when browsing in the internet in dolphin 6.1. Even if 2g on and i in im+ messenger. A couple of sites get away even 1%-2%. An hour in nonstop browsing can drain 60%. YouTube has to look at all when the phone charging for viewing video over a length of 5 minutes, eats about 6% of charge. And i bought a new battery yesterday. And with the same old time of discharge. New battery calibrated. And tried to change the firmware on froyomod same. Right now sitting on the cyan 7 and the same flow rate. Last DSIfix 2..34.
PS. When data off - phone not using too much 2-3% when talking half hour. In the night can drain 3%.
You better calibrate the new battery after the new one charged to 100%
It calibrated already. Same ****.
I got same problem with my MS. Maybe it's high time to change to a new phone
Dieabolo,
What settings do you use for your display, your current frequencies with vsel, are you using this phone in areas with great reception, do you have programs that ate always updating running (Facebook, twitter, weather apps, Widgets, news /sports apps) ?
Also I do like dolphin HD but try the opera mobile browser it'll help by compressing data so therefore less data transferred which ends up with less power being consumed.

i know for a fact, because ive tested it, that i can pull 11+ hours out of my droid. what you need to do is port MIUI to it, then get a lowvoltage overclocking kernal on it. i have a kernal that is 18 slot, and it can run stable at 220 mhz/1.26 ghz on userspace. run it at 220 mhz/900 mhz. if you clock it lower, then the battery life will decrease because it has to deal with a larger load, therefore, giving you battery heat damage, which means no more battery for you! i found that if i run the hight at 900 mhz, then it will have a chance to deal with all of the load. if you put it at 1.0 ghz, then it will ahve the same effect, but if your going to game with the droid, then i would put it at 1.06 ghz. my phone specs: OG droid, OC to 220 mhz/1.0 ghz, running MIUI 108050 on android 2.3.4. have fun!
Two things I would recommend would be to perhaps try a low voltage kernel, and to make sure you don't have any battery-intensive apps running in the background (Ebay, Lookout, etc.). You can check this by going to Settings > Applications > Running Services and seeing which programs are running.
Also if you set profiles withing SetCPU or another similar app, you can have the kernel drop to a lower speed when your screen is off or when the battery drops below a certain percentage. Doing these things should help you save some juice.
EDIT: I just read on another thread that the milestone has a locked bootloader, meaning you can't change the kernel. If this is indeed true, that sucks.
I calibrate my battery with this method:
1. Plug the charger in the phone, and charge at 100%
2. Delete /data/system/batterystats.bin using Terminal emulator or whatever tool
3. Restart the phone, and when it start to boot, and before the soft keys shine take off the battery.
4. The phone will run without battery, after a few minutes (2-5) put the battery in.
5. Left the phone charge for another 30 minutes...
But with CM7 for Mileston RC13 my radio don't work, and I have to restart it again to have phonee signal.
i am getting 4 hours tops of batterylife on my z1
i have maximum brightness auto turned off i have wifi and bluetooth off
i have a live wallpaper
i have skype steam running in the back
it takes 2 hours for it to drop to 50 and 4 hours to 0 from full charge on pretty much full on screen time
is this normal even on that kind of heavy usage
I would recommend using wakelock detector to see what's really soaking up your battery. It's a free application and it's pretty self explanatory. Charge up your phone and use it heavily again and report back to us with your findings through wake lock detector.

Have push mail on ? My phone was empty very quick before the update .257 but now its much better.
I think if you mean with 4 hours onscreen it is normal otherwise it is not.
Use wakelock detector already mentioned
4 hours on screen time with full brightness sounds reasonable. I can play heavy games for about 3,5 to 4 hours with medium display brightness.
Always keep in mind that the display is the biggest power consumer in modern Smartphones.

so the battery really is that bad?
using stamina it drops 20 or so % during the night
Actually the battery with its 3000 mAh is gigantic. And I think 4 Hours of heavy usage with full brightness is ok.
20% over night with STAMINA mode is too much though.

20% over night with STAMINA mode is too much though.

i have steam and skype whitlisted in stamina
really dissapointed in the battery life then
i guess theres no such thing as a full day of usage then
is there any smartphone that can handle that?
Do you actively use your phone all day (screen on all the time)?
With medium usage (WhatsApp, Surfing, Some calls) I can go for at least one, maybe two days.
I slept for 10 hours and my battery drained 9% with wifi and GSM on from full charge. your using the stock charger right? charging faster then recommended will reduce the life of the battery and can cause this kind of issue, but the phone is so new i wouldn't expect that to be the cause. I know the stock charger 1.5A. With a 2A charger it is likely the phone will charge at 2A.
Its probably a software related issue your having, but 20% overnight seems like a lot..

I would something is hitting your phone for wakelocks. 20% over night is a bit high. I know google currents is a know offender so uncheck that if you have it syncing. Try turning off google location access. Turn off gps and nfc. Using you phone at max brightness will always be very draining, leave on on auto unless your outside in daylight or in the car. Facebook is also bad for wakelocks. Any app that is polling for updates will be hard on battery. My experience has been a much improved battery life over my previous devices. On an average work day I leave at 8 and get home at 430, and I usually have 70-75 % by bedtime usually around 30%. I leave most my apps syncing all the time as well. I know the phone is new to you so I would say you might be playing with it more than you normally would.

I suspect that steam / skype will be preventing the phone from ever going to sleep.
I would suggest capping the max frequency of the cpu to quite slow or setting the governer to a conservative level (an app could be forcing the cpu to stay at a high frequency most of the time which will just drain the battery in no time)
However this usually requires a custom kernal or at least root which isn't very well developed on the Z1 yet.
If you can run a wakelock program that also logs the time spent at each cpu speed ... that would help people help you ...
As for any phone being able to handle it, unlikely the battery is relatively large but so is the screen, most phablets have only a fractionally bigger battery.
Only a full blown tablet will get you a much bigger battery that might be able to last you twice as long.
I typically go 3-4 days between charges on the .257 firmware without stamina mode and paired to a smartwatch 2.
I used to get 3 days on the 534 firmware with stamina mode! (i work in an area of very weak signal so i get 25% no signal time over a battery charge)
Hey guys, I've seen posts about people getting amazing battery life, both on stock and on a custom rom. I can never seem to get the same results, whatever I do. Sometimes, I'll toggle a setting and I'll see improvements for a day or two, then it goes back. Even more frustrating is there have been times when I turn the setting back to what it was and see improvements. It was like this for a while, but recently I've kinda gotten stuck with ~15 hours from 100% to 10% and nothing seems to change it. I have location on device only (its for weather, battery saving seems to be worse because Google services just syncs all the time and eats battery) and mobile data on. I've disabled pretty much every Verizon app and I just use moto display and the sleep thing. What else can I do to get better battery life short of a custom rom? The only reason I won't do a custom rom is because my parents won't let me spend $25 on sunshine, whether it's their money or mine.

I exactly get the same results as you. I'm on stock and disabled all verizon apps. A help could be really nice.
Keep in mind that battery life varies GREATLY upon usage. I can kill my battery in a matter of a few hours or have it last for nearly a week. Sync frequency, sleep time, connectivity, refresh settings, screen brightness, CPU usage, vibration on/off, number of wake locks...I can go on and on.
For example, I had my S4 last 5 days before it dropped to 80%, as you can imagine I didn't use it much. However, that same phone died in probably 3-4 hours on me also.
What matters most is if you have more battery life than your previous phone. Never compare your battery life to others.

I included some usage statistics in the ingur link. A lot of battery seems to be used by Android os and android system. Is there anything I can do to lower this?

What do you have your screen brightness set to? Your phone looks completely normal in terms of battery usage (Android/Google will always use a couple percentage).
Try turning off adaptive brightness and putting your device to the lowest brightness you can stand, that should add at least another hour or two depending on your current settings. 3 hours of SoT over a days usage with what looks like moderate use (YouTube, Messaging, etc.) isn't too bad for this phone.

Thanks for the advice! I guess I was expecting too much out of this phone Oh well, i'll just wait until i can get $25 in amazon or google play gift cards to pay for sunshine so i can get computerfreak's rom.
I am on CF's latest ROM and I'll say my battery life improved compared to stock, but not by much. I may get 6 hours SoT but my battery is down below 20% by the end of the day, and that is if I avoid playing games. Playing games all bets are off, the battery runs out quick.
There are some out there saying they get 8+ hours SoT and 48+ hours between charges. I call BS on that unless you are running minimum brightness and not doing any syncing or anything location based, and possibly even turning off cell data. Showing off with pictures of their battery stats and not telling the whole story.

If you unlock with Sunshine and install RR, you can use the custom kernel to tweak the CPU and GPU frequency to save battery life.
Additionally, there are other ways to save battery, like adjusting the pixel density and colors. (At least I think so?)
Greenify also helps. I think that is available for non-root as well.
Also, check your wake time. If always awake, could be the Google services running constantly trying to update.
There is an app to fix that, but I think it requires root.

also, my phone really likes to shut off before it reaches 0% battery. Is this normal?

I doubt its normal, buy I have noticed that mine does that too. It usually shuts down around 7% without warning.
