I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.
There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.
My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.
What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?

Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).
Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.
And I keep the power to the lowest setting on a daily basis.
The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.
Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.
Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.
my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.
My current numbers:
Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%
Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.
I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.
I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.
I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.
I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.
I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.
Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.

So for all the people that have their phone on the lowest brightness, but get a Display usage >50%...are you using your phone that much?
Because I have my display on auto, and my Display usage is a 32%, and that is still enough for it to be #1 on my battery use list.
First, let me get the immature response out of the way: "What sucks my battery? Your MOM!"
Now that that's out of my system, my battery drain is generally caused by the same things as everyone else: screen and TWS. Although I mitigate TWS by using the airplane mode trick which seems to still work for me.

I dunno, I just do. The way the thing works is a little tricky, it seems like it's absolute rather than relative, meaning if your display is already on the dim side, you need to start with your finger way over to the left to take it down the last few ticks. There's only so dim you can make it - the lowest brightness setting would look like a 4 or 5 year old phone at its brightest. That's true regardless of how you dim it. So you may just have it pretty dim and because of the way the notification bar thing works, when you put your finger in the middle, you're making it brighter without meaning to. But if you slide all the way to the left, it'll be as dim as you can make it.

+1 to this, after I changed this setting my time without signal is about 3% before it was up in the 50's. Good tip right there

I guess this is a commom issue... Unless epics hardware is sooo optimized and only sips power ;-)
Does anybody have data from other android phones - nexus, droids...?

3-4 hours of talk time takes up 70% of my use during a 10-16 hour usage. Second would be my screen.
My screen is 79% and cell standby only 7%
My screen is all the way down, even tho with the new update I notice my screen got dimmer than before.

This is my first tablet and not sure about battery life and everything. So I left my tablet on through the night and lost roughly 10% through the night. Not sure if thats normal or not. But if so, I will definitely be turning it off throughout the night or when I won't be using for awhile. But is there a standby mode or something we can put the tablet into?

I don't turn it off, no. One thing that will save you battery is to turn the airplane mode on when you're not using it.
I just turn off wireless and pwer off screen.
never been off
I never turn my tab off. At night.it will loose. 6 to 8 percent. At night maybe a bit more or less depending on how long its off.
And I use it often thru out the day
Awesome battery life
Haven't turned it off yet. I use it all day and plug it in at night around 20-30%, wake up charged and do it again.
I just turn the screen off overnight while charging; I leave wifi on to synch work emails & calendars. Nearly a decade of smartphone use has gotten me in the dedicated habit of charging everything every night.
Thing to keep in mind, tablets arent Kindles with week+ battery life; keep in the habit of charging it whenever convenient & you won't run out of juice unexpectedly.
I'm in the minority here.
I turn my Tab and Evo off every night, the phone just before bed. It save a bit of batt life and unwanted calls in the middle of the night or any alert tones as I'm a pretty light sleeper. I've also been doing this for probably 7-8 yrs with all my smart phones (Symbian, Win-Mo, Palm, BB and now Android).
Sometimes I turn it off at night, sometimes I just leave it on. It's definitely on ALL day. I haven't really seen it losing much battery if I leave it on overnight, but I don't have it configured to sync frequently. Whenever I notice the battery is getting a little low, I charge it up again -- don't really have a set pattern or routine that I charge it.
Anytime I know I won't be using it for twenty minutes or more, I just shut it down.
Not sure there is a right/wrong, good/bad way to do this, as it's pretty much a personal preference thang!
If I'm not gonna use it for more than a day, sure.
I also turn on airplane mode when I'm reading via Kindle or anything else that doesn't require wifi.
On a semi related note, does anyone else find the screen is too bright if you're in a dark room reading, even if you have brightness on the lowest setting?
So far I never see any difference to turn AIRPLANE MODE on... but anyway some people believe so... let say that work... hu hu hu
well
to answer I never turn off my tablet, neither turn off the wifi
I try to not use AUTO brightness, set brightness to medium.
I will turn it off... well... actually I do not.
to muqali. on lowest setting? on dark room lowest setting I think it's fine (but I have an antiglare screen... that dim the light)

That is crazy talk! I'd suffer some serrrrrious withdrawal
On to the question, no, my tablet stays on 24/7. The closest it gets to off is booting into recovery, but then it's right back on.
All my backups, security scans and cloud syncs are scheduled for the wee hours of the morning so wifi stays on at night too. Also, my iconia is my alarm clock, which is very useful for a shift worker who needs different alarms on different days.
only if the battery is low and Im to lazy to go charge it
I only turn my tablet off in order to reboot when it freezes up or gets laggy (maybe once a week). The rest of the time, it's on standby or being used.
I leave it on sometimes, other times I will randomly turn it off. I mean, its not a phone.. no reason it should be on 24/7. I don't even leave my PC on 24/7 - as it saves a lot of electricity to turn it off.
My phone (Droid X) however, stays on 24/7 =P
Yeah, I've been leaving mine on and its been just fine. I notice it turns off wifi or I guess at least disconnects when the screen is off so I'm sure that helps. At nights I guess I can turn airplane mode on and that should help. I'm impressed though with the battery so far.
I always turn it off when done, unless I know I will be using again in a short.

I use the Nook app as my eBook reader instead of the Kindle app. The Nook app has a separate brightness control within the app, and it allows me to turn even the white page brightness down to where it's very comfortable to read even in a pitch dark room. The nice thing about this is when I'm done reading and exit the Nook app, the global brightness settings for the tablet are restored so my dark wood wallpaper isn't too dark.
I'm not sure if the Kindle app has its own brightness control or not, but it might be with looking into.

yes, I noticed too, it's too damn bright, but not as bright as my phone, on the good side screen comparison between iconia, transformer, zoom and ipad2 the iconia gets praise cuz it's super dark black... you can notice easily (like me) if you're in the dark and look the status bar
I do not. I don't really ever turn mine off actually, except if the battery is at low and I'm out and not able to charge it, but that rarely happens.
I don't turn my PC off either. Turns out it doesn't save as much energy for me vs. time. I'd save roughly $90 a year if I diligently turned my PC and HTPC off...my PC however serves as the file server for everything in my home and I'm also very random in terms of bed times so it would cost me so much time (and maybe some parts issues as well) turning it on and off every time I needed to use it.
Ok. This is extremely wierd.
So unplug my phone off the charger in the morning use it a bit. 1hr later I feel it burning a hole in my pocket. Its extremely hot, I take it out and try turning it on but the screen wont turn on. Battery pull and its fine.
Go to battery history and the battery life vertical dropped 15% in that time.
Happens 1 to 2 times a day. Any idea whats wrong?
Thanks
Had the Phone for just over a week now battery life seem to die really fast screens shots of my usage took of charge around 10am and was down to 26 around 7:30 took a few pictures and placed calls etc but still
Brightness if Full dont like dim screens
Touch key is always on
Well full brightness on a screen this large is always a battery killer, and touch key lights plus haptic feedback don't help matters. You've got quite a bit of screen on time, but I'd be concerned about that WiFi. There's some settings that can help in the WiFi menu.
1) switch it to WiFi awake only when plugged in
2) turn off always scanning.
The WiFi being on and awake constantly is a definite drain.

Hi, new owner of DT2 after returning my galaxy7 edge. I'm having an issue with wake lock. When I don't use the phone for an hour or so, and haven't touched it, my battery barely loses anything and the wake time under the battery setting reflects that. But when I'm casually using it - sometimes using it for two or three mins, then not for 29-30, my phone seems to stay awake a lot when the screen isn't on. I thought this could be a rogue app, so I'm running it in Safe Mode, but I still see the same trend. Does Moto active display cause the phone to wake every time it reads motion?
Attaching screenshots. The battery charts are when I had it in Safe Mode. The gsam readout was in regular mode. Based on how active the phone was, I would've barely gotten 2 hrs of SOT
Hi. Generally, Doze, the feature that allows your phone to barely sip power when your phone is not in use, will not kick in until around an hour. Yes, Moto display will wake the display every time it thinks you are trying to use the phone but it should still use only a tiny amount of power. Also, don't put too much stock into the projected battery chart. Sometimes, it is very conservative and other times, it is wildly exaggerating. Hope this helps.
I did a factory reset on my phone and left the phone sitting for about an hour. The awake time was still represented about 30-40% of time on. My phone has been getting about 2-3 hours of SOT over the course of a 12 hour day. Seems like the awake time is really eating the battery. I wonder if others are having this issue. I didn't have the phone before the Marshmallow update, so don't know if that's the culprit.
I have noticed then when I keep the phone aside overnight.. idle condition (wifi off, location off, data off) and go to sleep.. I wake up with a drop of 8-7% drop in battery, is it normal? Because none of my previous phones showed such a drop in battery. Anyone else facing the same issue?
