I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.
There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.
I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.
You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

You just said your phone is at 36% eighteen hours after charging! Compared to the 0% I'm at ten hours after charging...I'm not looking for superb battery life at all, just somewhat decent. I'm actually bringing a backup feature phone with me to college this semester in case I can't resolve this issue, because I will need to use my phone both in the morning and at night some days

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.
The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.
There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.
I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.
Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.
You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.
2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...
i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.
I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it
Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge
Hey guys,
I just recently got a refurbished phone from T-Mobile's insurance replacement. My brother gave the phone to me instead and opted for something else. So phone right out of the box had 100%, used it lightly and I noticed every 4-5 minutes that i spent looking at the screen the phone would drop between 1-2% and this is just me looking at settings and downloading updates. So I figured maybe it was just the updates being intensive.
So I get my case and screen protector and I turn off my phone and let it charge on off to 100%. Turn it back on and start using it like I normally would (keep in mind if I have stamina on) I like to have my screen brightness at the highest while watching videos so I watch 3 videos over my LTE connection on youtube and then I hope into my car and listen to a audio book that's already downloaded. Time lapse was probably about 30-40 minutes.
When I get home the phone is down to 85%. Is it normal to lose 15% in less then a hour on this phone? This worries me because I want to utilize the life log and during my 9 hour shift at work I listen to spotify about 6 of those hours... maybe I have a dud battery? Every where I go everyone says it lasts all day with moderate use... but at this rate my phone would be dead before my shift even ends...

Um what? What kind of phone did you have before? Did it have better battery life? Because the only phone I've ever had that had better battery than the Z3 was my Z1C (usually 7 hours)
Also, max brightness and 5 minutes per 1%? You know that equals 8 hours of screen-on time? IE a better battery than ANY PHONE ON THE MARKET HAS? You need some perspective, your expectations only make sense if you came from a Nokia 5110
I had a iphone 4S before this. My expectations are like this because every where I read reviews everyone says "insane battery life" "Lasts all day" and even the sony site boasted how the phone can last all day with stamina off and with stamina on it can last 2 days and with stamina ultra supposedly a week. This is why I'm worried about what's going on with my device.
If there are better sources with realistic numbers i'd greatly appreciate it to put me to ease.
I just set all the settings on my phone to get the maximum battery life except ultra stamina and even froze/disabled apps that i don't need. Yet I'm still draining just the same, I like to watch videos on youtube and play spotify and watching vids on youtube for about 30-40 minutes I drain about 10% with all the new settings. Brightness is also on minimum now and have that option for it ticked as well.
Just wanted to give feedback on the phone and having it for a week now. The battery life is truely amazing, It almost drains nothing when in standby its like the phone isn't even on at all yet sync is coming in with updates. This is a great phone and I have yet to have it die on me before getting home.
I realize there are several threads about battery life, and I apologize if this has already been posted, but I'm in full-on battery drain mode right now and am having a crisis. Is there a thread that addresses this or a quick fix? Any suggestions? I've dropped 38% in an hour with 20 minutes screen time. It's been great for the week leading up to today. I've already powered down the phone. I could stop Google Now, but this hasn't been an issue all week. Not sure why it randomly would start one now. Thoughts? All help appreciated.
Haven't logged in in a few years but account is behaving as of it's a new one. I used the original Galaxy Tab 10.5 boards frequently.

I would think you have a app thats constantly running looking for GPS or syncing data.
Thats with just over 2 hours screen on time and GPS being used constantly for 20 min on my run.
Also if your in poor signal area or roaming a lot you'll burn through battery.
Yeah. I'm not sure what's going on. I decided to clear the cache for Google Now. I also turned the phone off and am powering it to 100%. Once it reaches a full charge, I am going to remove the battery, hoping for some kind of reset. I'll then let it fully load for a few minutes before checking on it.
Like I said, it was working perfectly for over a week, but for some reason, it went into battery drain freefall mode. I thought it was aggressively falling upon waking this morning because it had 98% before I went to bed last night and when I looked at it after using it for an hour this morning, it was around 60ish%. I fast-charged it back to 98% before heading out the door for an appointment and turned on bluetooth so that I could listen to music in my vehicle. When I got out of my appointment an hour later, it was back down in the 60s and I was totally confused. The music had been shut off and the screen was not on. The back of the phone felt pretty warm too.
I agree. Some process must be running endlessly. When I had this issue with a G2, I was able to pinpoint it as having something to do with Google Play Music and was able to fix that by altering some settings. In this case, it looks like the culprit is either Google Now and / or Android, but as I said before, it doesn't make sense to me that it would start happening out of the blue like this when it wasn't occurring before. Usually screen is (understandably) my biggest battery drain. I don't recall seeing Android responsible for over 20% like that before, outperforming the screen that much in the battery drainage department.
I'll report back once it is fully charged and I get a feel for whether the issue went away.

You can also try downloading CPU spy, it's a app that'll show if your device is going into deep sleep properly. https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy.realgpp
Way-too-early impressions are that it is back to normal. I have no idea what happened. I read in the Battery Life thread a little bit ago that some were suspecting that flip cases have caused some issues. That might be relevant here as I do have a flip case even though it didn't give me any problems. I was, however, messing around with it last night because I purchased a Scosche Magic Mount and was trying to determine where to install the large plate only to discover that it didn't fit properly behind the flip case backing. This fiddling caused me to pull the battery and take the case off, among other things. I'm wondering whether the case was properly re-installed.
Another possibility is that I use UCCW for a Google Now widget and while it has worked perfectly with my previous two phones, with the Note Edge, it doesn't appear to activate the Google Now screen even though it acts as if it is listening for you. Even though I terminated Google Now when that happened this morning, I guess it could have played some kind of role.

Thanks! I'll check it out!
So far, I have lost 4% in 20 minutes. While that's not "great," that's about where I was. I don't use powersaving mode and use my device pretty moderately. I can usually get through most of the day without a charge.
I took advantage of the BOGO offer from Verizon and got two LG G5 at Costco. I've been using my phone lightly, but I can't help but complain about the major issues that gets everyone else talking: Battery life.
I see other people have screenshots of achieving 6-7 hours of SOT, but I'm seeing nowhere near that. The most SOT I can see is having 3 hours before hitting to a depleted battery. Occasionally as well, the phone feels pretty hot to touch when it idles or have some fair amount of usage. Even right now I have it inside a thick, bulky protective case, and i can feel the heat from the back. Is it the SD820 or is there something off?
Just to make a comparison, I have been using the Sony Xperia Z3v for a year and a half with Verizon since its release and it's a great all around phone. I usually achieve 5 hours of screen on time or even more depending on how heavy I've used it. Waterproof, dual front facing speakers, 20.7 MP camera (although very outmatched by the G5's), and the power saver absolutely works. What I mean by that is that when the power saver is on in the G5, nothing seems to load at all.
So the overall question is, how is this phone for everyone? I absolutely love the camera, but the battery drainage and overheating is an issue for me. I've had thoughts about exchanging for the S7 Edge since it's pretty much a direct upgrade of my Xperia, but I'd like to see what the G5 can really offer. Oh and, how long is it until I get the extra G5 accessories from doing that bundle deal? Thanks.
You know I've noticed peoples complaints about that but to be honest I think its just certain phones that had these issues. I don't know how but mine hasn't been hot since I first set it up. My battery life lasts me a full 8 to 10 hours depending on if I do too much gaming or YouTube. Those are my biggest battery abusers. But I made sure to deactivate the bloatware Verizon wanted to install. I've had a good experience with mine. The only time I've been mind boggled was when out of the blue chrome would cause the phone to freeze up till I reset chrome. Other than that my device has been running so smooth.

I've been one of the people complaining about battery life. In the first week or so that I had my phone, battery life was miserable. I need to be completely honest here though. After getting into my second week of using this phone, my battery life has greatly improved. In my honest opinion, I think it needs about a good week to 'settle' or 'break in'. I've done nothing different done I set my phone up and I have deleted any apps or anything. I don't know if this is the case for anyone else or not.
I like the phone a lot. It is fast and everything works well.
The only things that I want improved are
1) Screen brightness adjustment. Too dark in dimly lit areas and too bright in normal room lighting.
2) Battery Life. This is a strange one. Some days I have really good life, but sometimes the standby use it high. Google Play Services sometimes eats a lot of battery. I have to reboot to get it to stop. There are also people saying that being on wifi causes more drain. I thought this was not true for me, but I am rethinking. It may be higher when I am at home and on wifi.

So far, I've yet to achieve substantial screen on time. It's really strange, I was having my phone used from 330 to 830 tonight, and it went from 100% to 45% with only 50 minutes of screen on time. WiFi and mobile data off, and I wasn't taking a lot of pictures.
One thing strikes me is the Held Awake/Doze clarified by GSam. That's eating the most battery, what exactly is it?

Honestly, I'm not positive. Make sure in your display settings, though, that you have 'screen always on' turned off.

I haven't been able to figure out why sometimes GSAM shows very little held awake with the phone deep sleep for a majority of the time and sometimes the held awake is almost the entire time since the phone has been unplugged. It seems that if the phone gets into the held awake state that you can get out of it by rebooting, at least it seems like that to me. I have not had enough time to come to firm conclusions on this. I am pretty sure that the held awake has something to do with Google Services or Play Services. It would be great if we can get root and limit the wakelocks from these. Just have to wait on that.
Pretty solid compared to the G4. No heating issues, battery lasts longer as well. I'm at 25%, 11h 7 min on battery 2hr 53min screen on time.
I average 14.5 hours total, 3.5 screen on time. I have noticed turning wifi off when I'm not using it saves a pretty decent amount of battery, which is odd.
I'm not upset with the battery life or anything, it's better than my S4 and G4 were, but if the S7 really lasts 7 hrs with screen on.... i don't know. I have another week to decide on restocking. I do love how quick it is, it's beautiful, feels great in the hand, and the option of removable battery.
I like this phone, and while it is better than the G4 in every way (very buggy, lag, missed taps, etc), I now get paranoid about any tiny bug on this thing and wonder if a Galaxy would be more reliable.
My first full charge I got 45 hours of battery life with 4 hours of screen on time. However that was before I had all my apps reinstalled and that 48 hours with 4 hours SOT included reinstalling all of my apps. Screen brightness on auto the entire time.
Since then I've only been getting 4 hours of SOT with 24 hours battery life. That's only 4 - 6 hours more of total time on an no more SOT than what my 2 year old LG G3 was getting.
LG skimping on the battery was a mistake.
Hello all,
I just bought a new galaxy s7 silver (exynos variant) around 3 days ago and my battery life seems to be really bad. I've only managed to achieve 1h 56m screen on time and I'm already at 41%! I keep auto brightness on and leave always on display off and don't keep things like mobile data active. If anyone can suggest how to fix this it would be phenomenal .
I was quite sad considering I have heard of people who can achieve 5+ hours screen on time with regular usage and not having to compromise on switching everything off .
Thanks for the help in advance
Do you have Google Chrome installed? And can you see something like "media server" in you battery usage log as a high power consumer?

I would send you a picture of my battery statistics but for some reason every time I try to upload a picture I get "network error"
My top consumers are :
Screen 31%
Android system 19%
Android OS 9%
Cell standby 7%
Mediaserver 4%
And Also I do have Google Chrome installed
Good day.
Try this and see if it works:
-In settings -> privacy and safety -> location -> improve accuracy - Turn off wifi scanning (The phone turns on and off wifi regularly for location purposes and it uses some battery)
-In settings -> Display - Turn off smart stay
-In settings -> Advanced features - Turn off pop-up view gesture, Smart capture, palm swype to capture, smart alert and easy mute.
-In settings -> Accounts - Turn off auto sync
Turn off hardware step counter at S-health app.
Use Greenify to hibernate samsung and google play app and services.
And if you want to stretch it more have a look at this (http://forum.xda-developers.com/galaxy-s7/how-to/touchwiz-bloatware-save-to-remove-list-t3330241)
Hope it works for you.

I was quite sad considering I have heard of people who can achieve 5+ hours screen on time with regular usage and not having to compromise on switching everything off .
Thanks for the help in advance

Hi mate,
The 2nd guy in this post touched on it. When you see Mediaserver on your battery stats it's normally a sign that your phone, since being on, has got quite hot and there has been substantial battery drain. I've had this same issue before too. Factory resetting etc wouldn't help. And the phone would get so hot. Eventually I read and found a link between Google chrome and Mediaserver. I deleted chrome and mysteriously the issue left, that was on my last s7. My current s7 I got yesterday and haven't got this issue once, despite using chrome right now.

Yeah I did notice that the phone was heating up rapidly and my battery life was falling heavily. I will delete it and give an update to see if it works.
Thank you
Right I tried it and at first I thought that it worked but then today I am down to 25% with only 2h 5mns screen on time. Anyone got any other ideas?
Sorry read that wrong lol I read 25% battery for 2 hrs screen on time!
Accounts syncing in the background could be a culprit or some of the fancy software functionality that Samsung cook in to touchwiz. I generally don't have anything working or syncing that I don't use.
Might be worth going through all of your settings one by one. That's what I did when I first got the phone.

I'll give it a shot , how does your battery life seems to do? also, do you use power saving mode ?
At this moment in time I've had 2 hours 44 minutes of screen on time and I've got 53% battery left.
The majority of that usage has been on WiFi though and I do have auto brightness enabled. One thing I have noticed about the s7 screen is, it is very good quality and incredibly bright. I have spent a good amount of time tweaking the auto brightness so the screen isn't any brighter than it needs to be in various light conditions.
I was suffering from rapid battery draining and the phone getting overly warm when I had Google Chrome installed. I've removed it, and it has taken those issues away completely.
I have come from a nexus 6p and don't miss the extra 500mAh of battery to be honest.
3hr 28 minutes of screen on time now with 43% battery left. Still on WiFi but have been playing a bit of order and chaos 2, reading the news, browsing forums and general Internet surfing. I don't have much on in terms of push notifications other than Gmail and have my Samsung Internet app syncing and some stuff related to my Google account.
If it's of any help at all, my phone is on the 3 network in the UK running the stock 3 branded firmware.

Good news mate!
Alright all was going well regarding batteey life until recently when it began to slack off again. I hopped in to srttings see what was consuming all of my battery life and it said android system. Anyone know what that's all about?
