[Q] Why is my phone draining batter so quickly? - Galaxy S 4 Q&A, Help & Troubleshooting

It doesn't drain so much when I'm not using it, but when I use it, its incredible how fast it drains. I will provide a few screenshots.

You don't have drain. Your screen needs power to work.

When your phone spends 40% battery life in 3 hours, you do have a drain, specially when the screen was on only 1 hour out of those 3.
Maybe you are used to having terrible battery life, but my phone's battery life used to be 24h at the minimun even if I used it a lot, I don't know what's gone wrong. I woke up today and my phone was dead. The battery lasted 10 hours and 23 minutes.

You are really confusing things. The 24 hours you are talking about is standby time.
65% of the 40% comes from your screen. Your screen on time is 1 hour and 25 minutes. That means you will get something between 3-4 hours screen on time total. That's perfectly normal.
Maybe I am mistaken and you got drain, but not based on those screenshots you show.

Sorry, but that's not normal, not for me. I've had up to 6-7 hours screen time on.
Like I said, maybe you are used to this kind of battery life, but I've had my battery life last 36h with little use and 24h with several hours of screen time. Why does it only last 10 hours now with just 2h of screen time on? thats what I want to know.
I remember I used to charge my phone once a day, and I used it as much as I do now. Will post more screenshots later today right before my phone dies.

6-7 hours is impossible to achieve when using your phone normally. But lets leave that discussion for now.
The screenshots you gave:
It drained 42% battery.
65% of the 42% battery is caused by the screen. That's 0,65*0,42=27,3% of the total power consumption.
That leaves us with 42%-27,3%=14,7% other drain in 3 hours. You had your phone in use (screen on) about 1:30h. So the drop in battery is really not uncommon. In my experience that's normal. I even see that you used a videoplayer.
If you are sure that you have drain, then try to compare the screen on time with the awake time. If your phone is more awake then your screen is on (a significant difference), then it's possible you have drain.

Lennyz is right. This is completely normal use on a stock battery. I literally wrote the thread on great battery life. (See signature). I get 4 days standby time routinely. So I am confident in saying that this battery life is normal. But no matter what, you can't push past 4 hours of screen on time. The battery isn't a little sustained cold fusion reactor or something.
Now, if you have an extended battery then something is wrong. My first guess would be that your extended battery is dying.

I understand what you're saying. But I'm telling you I used to have much greater battery life. My phone used to last 24h at the least and I use it as much as I did then (not too long ago). But if you think this is normal then I guess you can't help me, thanks anyway.
I went to sleep right after taking this screenshot (Phone was dead when I woke up 7 hours later). So yeah, thats the screentime on I get now, doesn't even reach 3 hours.

You need to look at the awake time and compare it with the screen on time. That way you can check if you got wakelocks. You need to press the graph to see it. eg in your last screenshot press the area that says 8h6m57s.

setCPU dangers

I get pretty crappy battery life on my poor little N1. Cell standby takes up 49% and phone idle 49% when I go into the battery information. I am considering setCPU but I'm scared that if it's changing the clock speed every time I turn the thing off isn't that bad? I mean having the clock speed adjusted so many times, couldn't that hurt the device's life span?
by default on stock it already scales the CPU to conserve battery
My battery life has increased since I've used this program its awesome
Cell standby and phone idle at 49% each isn't a problem if that's all that's been using it. It doesn't mean each one will take up 49% of your entire battery. If you just unplugged it and let it sit without using the screen or anything, then the only thing using your battery is the standby and idle. So after 2 hours or so of that, you might be down to 90% battery, and both cell standby and phone idle are using 49% of that 10% each. In other words, it used up 4.9% of the total battery each.
As for changing the speed all the time, it will not hurt the CPU, as Android already does that for you all the time. When sleeping it under clocks to the lowest, and when you need to use an app, it clocks it back up to full power.

I've been using it for 4 hours and they're both 49% and the screen is only 2%, is my phone defective?
Have you been using the screen during those 4 hours? Like using it to browse or run apps or anything? Or has it just been sitting there for most of the time?

Sitting there mostly. Here's a screenshot I took yesterday:

Absolutely no use whatsoever and it's lost 12%?
That seems perfectly normal. Don't worry about it. It does have to use power to idle there, it is still a running computer, and it also needs to stay connected to the closest cell tower in case you get a call.
When it is sitting all by itself that is all it has to do. Your screenshot shows that in 10 hours it only took 12%. That is very good.
If you used the screen for 5 of those hours, your battery could be down to much less than half, and the screen would be about 90% on that graph, while the idle and standby would be less than 5% each.

I only get 2-3 hours if I'm using it for internet I'm not sure if I need setCPU or of it does it for me
I really wanted a desire rom but everyone goes on about how bad the battery life is on them. It doesn't make sense because the desire has a 1300 battery when we have a 1400.
Ok, that is a problem. When it is idling your phone seems normal, but I am able to get more than 2-3 hours when browsing the web.
SetCPU won't help you that much, well it can help, but it is best to find out why you are so low in the first place. Fix that first to get it to a normal length first, then you can look at extending the normal time to longer with SetCPU and other things.
As for right now, what brightness do you have the screen on, what are you normally browsing on? I usually use it at a pretty low setting because I am indoors, and browse pretty simple websites.
If you use full brightness and watch youtube videos you probably would drain the battery insanely fast.
What are you normally doing when it drains so fast?
30% brightness and just casual browsing, some forums mostly.
Since your battery isn't draining by itself, I don't think it is a rogue program taking the battery.
If you are using 3G with a really bad signal it could do that, as it has to boost the power to reach the tower.
Otherwise I am at the end of my suggestions, you could try reading through a few of the large battery threads until something sounds like it could be your issues. I doubt you're the first person to have whatever issues you have.
I live in rural Canada. I think it's rather mutual that I get crappy service
I would love an extended battery, but unfortunately I know nobody who's actually used one who could tell me how good they are, or where I could even obtain one where I am in Canada.
It's mostly the desire rom I really want though, but the blasted battery is supposedly so bad for it!

I don't think so because I've been adjusting clock/bus speed on my psp for over two years now and the battery life seems perfect and the processor too...

turn off bluetooth, gps when not using. Use a task Killer to end all tasks that you arent using to stop them polling for updates and what not. If using Facebook, Twitter and rss feeds they need to be set to update at intervals >3/4hours otherwise your battery will be absolutely ****e.

lets see who has the most battery life

i wonder who has thebest battery life 4 samsung vibrant i get 6hr 40 min full charge nd i m running the obsidiyan 5 beta rom i think i spelled it rong
Ive gotten 12hrs. with moderate use on obsidion v3. On v4.2 not do much.
Fear the beard...

I win. And after actually doing a full calibration of that, i got ~65 hours total
I was at 2 days 9 hrs with 19% battery life left before I plugged it in the other day.
That would be equiv to 57 hours with 81% drain.
If that was a straight linear drain and with a fully calibrated battery that would be an estimated 72ish hours of battery life.
I am running Onyx 4.2.
i got 4 days 8 hours 12 minutes. still running at 16%.
19% @ 21h 6m 44s since unplugged
but i don't remember if i rebooted or plugged in the usb somewhere along the way. either way, acceptable battery life, maybe slightly better than JI6
obsidian v4.2
edit: w/ stock kernel. i've heard the UCLF kernels have been having battery issues
Anyone can get 60 hours if you unplug, connect to wifi or turn off data and let your phone sit unused...these threads are pointless...
haha holy cow thats a long time with ur battery what do u guys not useur phone a lot???? =-O
Who has a longer battery life? Toyota Prius!
How can you compare battery life on a device that is being used differently from person to a person
Use System Panel statistic at least! I got -1% per 6 hours of sleep on Obsidian v4.2 and ~6 hours of constant usage.
So are you guys using eugene's kernels that give you actually ALL of the battery life by letting the battery die at 3v?

Exactly, even turn off wifi for more juice!!
Realistically, the best I have gotten was 24-25 hours (moderate use)
i actually use my phone normally, for me at least. and yes, i can still get 60 hours. i don't have a data plan, so i use wifi. I text throughout the day, but i'm not a "heavy" user so that's why my battery is higher.

Here you go! Most of has data plan and always connected to 3G, sync contacts with FB, google etc, email client, weather widget, FB feeds, stocks, news blah blah blah...I get 16-18 hours max with all this running and moderate use.
played angry birds for 3 hours straight, still at 90%.
I hit a record.
Yesterday riding around I must have watched a few YouTube videos and surfed the web/used XDA app to read forums. Perhaps I sent a text or two. No phone calls, GPS, or WiFi, though...
2 hours 34 minutes (yes, that's kind of ironic numbering, but that's what it said) later it was at 27% battery life left.
I now have like 80% of the Apps I had installed before uninstalled, so I know it's not a software issue with something draining the battery.
Display was taking 77%. Samsung initially stated that the sAMOLED screens would not drain as much battery, I think that is likely the culprit for many of the battery woes. I will be sure to avoid this screen type in the future.
My HD2 has a much smaller battery, but with the same usage patterns it runs circles around this Vibrant. It's not even funny.
The Vibrant can maybe standby for a day and a half. I can use my HD2 casually but let it stand by a majority of the time and the battery lasts like half a week...
I think the Screen is the culprit, IMO, which would explain why people who turn off auto-brightness and fiddle with that see much better battery life. On the flip side, the issue is exacerbated because the Vibrant doesn't have an LED Notification light (like the HD2), so everytime you get a text instead of using an inexpensive LED notification light, it's flashing that screen on. That means even if you don't use the phone all that much, your standby uptime can still be deplorable compared to some other phones if you get a lot of phone calls or notifications which turn the screen on.

I'll believe that when I see it. In any case if I play a game that long on the phone (I never do, but IF), I'd be at a charger, anyways.
21 hours to 50% ON STOCK
I got 21 hours on 50% drain using the juice defender on the stock rom. Not bad i would say especially considering what I was getting before I took steps to conserve battery life.
As someone else already said, this is kinda pointless. Everyone is gonna use their phone's differently. With all the apps, configurations, etc, there are literally millions of different variables.
Something that I find puzzling... I see so many people upgrading to 2.2 only to get 6-12 hours battery life. Why in the world do people accept that? What is so great about 2.2 that people are willing to settle for having such piss poor batter life just so they can run 2.2 on their phone's? I don't get it at all. The best I could manage on 2.2 was 18 hours. That rom came off my phone so fast it wasn't even funny.
Anyway, with normal use (read: light to moderate) I get just about 3 days with my phone on 2.1 Bionix. I wouldn't be considered an average user though, as I don't have 3G in my country and my widgets only moderately access the web. What helped me immensely was disabling data when I don't need it. I mean, do you really need your phone checking your email, weather, facebook, etc, while you're fast asleep?
i can play pocket legends for 3 hours straight from 100% to 5%. think it's good but not enough.

Battery Life - How's Yours?

What has been the average battery life with your TF? Mine has been good but feel like it could be better. Today for example, after charging and an hour of soem use, it was already down to 90%...but observing, it may also have like a "sweet spot" in the % meter as I often see it stay in the 50% to 30% ranges longer than the 100% to 90%...
Pretty damn good, I usually OC mine to 1.4 and have it at performance and it still lasts like 8 hours.
I have gotten into a habit of leaving mine in the dock until the dock battery is used up and then I will switch between netbook mode and tablet mode. I'm not sure on actual hour usage but I usually get between 3-4 days. And this is really my only computer at home, so I use it quite a bit.
With average use, youtube, games, reader, web browsing about 2-3 hours a day I only have to charge about twice a week. I love it. In the one test I managed I had my screen at full brightness and always on, gps and wifi tether running while I drove around town taking my wife to yard sales I ended up around 7 and half hours before i reached 15 percent. I'd say its pretty damn good. A hell of a lot better than my Adam I had before this.
Really good. Charging every couple of days
pretty good, i dont use it all at once but if i use it normally charge every 2-3 days
Mines pretty good, OD'd to 1.5 idle at 4XX. Yesterday on a 12 hour work day: browsing about 2 hours, Fring calls, playing games for about 2 hours, USAToday/CNN apps about an hour, Polaris about 45min, and watched The Hangover at 720p.
When I got home I still had about 41% left on the battery, it was on WiFi all day, bluetooth off, and auto bright on.
Lasts 8 hours if I continuously game on it.

10% down for an hour of use means at least 9 hours till you get to 10% which is pretty good, and just like the producer specifies. It's better than any other Honeycomb tablet out there, including Samsung's Tabs.
I can get on my TF to 11-12 hours of moderate web browsing (forums and static blog pages, not much power hungry flash) with auto-brightness (in fact close to 10%-0% brightness cause I mainly use it in the evenings, in a low lit ambient) and other than WiFi radios off, before it reaches 10%.
That's good battery life. Comparable to my wife's iPad 2.
I was out at work for 14 hours, when i came back,my battery has fallen by 22%. This happens often. In battery usage graph, i see that my tab was been awake intermittently a no. Of times during the time it was on standby, i mean like it was awake 50% of the time, in short bursts. At the same time, wifi was also on for very short intervals... my wifi is set to disconnect when screen off. I hav pulse,news360 and youtube widgets. And the asus time n weather thing. My mail did not sync during the standby time, as i received the gmail notification sometime after i switched it on. So it was probably an app that was causing multiple 'awakenings' ! Ne idea wat? I dont sync with picasa, so that may be ruled out.
Ps-this was undocked.
Pps- i found out the picasa sync option was checked, so i unchecked it. But i dont know if the battery drain was due to this. Isnt there any app like spare parts that can atleast tell the no. Of times/duration an app was used?
Sent from my Transformer TF101 using XDA Premium App
after using mine for about 24 hours fairly heavily, and having it oc' ed to 1.5, and a fair ammount of gaming, id say i could get a solid 7 hours of use out of it while still gaming a good ammount. Prob more, but no long term results yet.

What can one do to squeeze the most out of the battery.
- keep the the brightness at 50%
- set wifi to turn off when the tablet is on standby.
Anything else?
My stand-by time has been horrible. From 100% down to 85% overnight, then down to 35% after 16 hrs, and the next morning, 15% left! So I literally have to recharge every other day even with very light use!
I have set wifi to disconnet when screen off, and I have weather, pulse, gmail and c-note widgets on
I use my tablet for email, sometimes youtube and lots of games. Its on stock 3.1 with root and OCed to 1.4. It's probably like 2 hours everyday usage. I only charge it like twice a week.
I set my brightness to Auto, Wifi is on, might disconnect when screen is off, not sure.

cell standby usage

Is anyone else having high cell standby usage? My phone has been off of the charger for about 3.5 hours. I haven't made any calls or used it for any music or anything. The battery is now at 72% with the biggest user of battery being "cell standby". I have all of the power saving features turned on. I googled it and saw that some of the international s3s are having the same or a similar issue. In their instance, it was an issue with the radio.
ideas?
Have you rooted it or anything? Mine has been getting excellent battery life with moderate use. Took it off charge yesterday around 10am checked the tropical storm throughout the day and other stuff, by 9pm it was still around 70%

I've seen other folks complain about this. In my case, I have more time off than on, and would expect standby to be a higher percentage than other things...based on my current usage. (Been trying to see how long battery lasts with screen off. Looking pretty good so far. Can see results here).
I'm not rooted. The only reason I bring up "cell standby" is that it is the only thing that is high. A phone shouldn't drain 10% per hour while it is just sitting there. It's 11:30AM now and my phone has been off the charger since about 6:30. Now I'm at 50% battery.
I did read in some other posts that it may be related to LTE being rolled out. From what I can tell, the nashville area just got LTE within the past couple of weeks. I could be flipflopping between HPSA and LTE.

Lucky you, I have to go to NYC or Philly for LTE. There's a post on GottabeMobile with a simple working fix works on rooted and non-rooted phones: http://www.gottabemobile.com/2012/0...how-disable-4g-lte-use-hspa-conserve-battery/
fyi, i think i may have fixed my problem. I reset the phone to stock and then let it reinstall all of my apps. I have all of the same apps as before, but the battery life seems better. I did this at around 5 yesterday and only drained off 5% or so of the battery between 6 and 10PM. Today I've been off of the charger for an hour and am still at 97%. I will periodically check it during the day.

Interesting.
I'm not really sure what to think about the Cell Standby thing. I've seen quite a few complaints about it. Thinking of your comments on battery life, take my battery usage per my post here. You'll notice that the time while on battery is 1 day, 8 hours, 25 min., and still had 35% left. Cell standby is 45%.
Of note about that is that I had the phone on approximately an hour and half. My test was for battery time basically in standby. I think the length of time ie excellent. Yet several have pointed out the 'high' cell standby. My thought is that if not using the phone, that will be the main thing happeninng, so logically will be a higher percentage of battery use.
Regarding battery use, I am not finding that I get that great of a time when I have the screen on a lot.
In the end if DEVS do something to bring down that cell standby time, it can only be good
I've had a similar thing happen to me yesterday where my battery drained 40% in like 3 hours with 'Cell Stand By" at the top. I ended up rebooting my phone and everything was fine since then.
Yes, my battery life has been terrible.
I had tried out a Lumia 900 and was getting much better battery life. I live in an LTE area.

i'm still at 87% after about 6 hours off of the charger.... with the same usage pattern as yesterday. I don't know if the reboot or the wiping of the phone fixed the problem.
I have been getting great battery life. On my first charge after I got the phone I went 1 day and 15 hours and still had like 10% left. I just put it on the charger a little bit ago and had gone 1 day and 12 hours again and had 30% charge left.
I have brightness at about 55% and power saving on except I have the CPU set to full power instead of limiting it.
It looks as the problem has been found on the international version. Maybe it can be implemented here in the states version

mine has been good since i wiped the phone and started over. I listened to pandora from around noon until 4:30 yesterday. i had around 60% battery when i plugged my phone in to charge at 10:30 last night.
I would beleive we have the same issue as my standby is high but i get great battery life so it didnt make sense...now it does...no big deal just know tjat what your seeing for cell standby is incorrect.....good find
I get two full days of use before I need to recharge. I dont turn the phone off over night and I have power saving off. Beats my x10 hands down

I'm not 100% convinced that cell stand by is a battery draining culprit. my cell standby is 50% after 1hour since unplugged and my phone just went to 98% just now so I am not seeing a HUGE battery drain because of it.. i think its probably a rogue app that is causing a wake lock. For those of you that is seeing unreal batter drains have you installed betterbatterystats to see if you can pinpoint the drain?
Ok my issue also went away.
When I signed in to my Google account, it installed all of my apps from my craptivate. Today I want through and deleted the ones I never use and now my battery is lasting almost twice as long.

How is the battery life on your Verizon s7 edge

I wonder if android system drain is same as other model. Seems like att also has the same issue, but one can dream.
Through the two days I've had mine, reports from other models have held true - Android System is the highest on the battery use list at around 30-35%. That said, I'm still getting 4.5 - 5 hours of screen on time, so the high Android System use isn't taking a major toll on the battery life.
Wait a week before answering this question. Everyone is going to be using their phones A LOT in the first couple days (tons of screen-on time) and in the meantime many things will be syncing and caching in the background for the first time.
Also, don't worry about what your battery stats says unless you are actually getting bad battery life. Android system notoriously is getting a bad rap right now even if the user's battery life is fine. Just leave it alone and enjoy the phone.
Cheers
OK! After a few days with brightness at around 15%, location on battery saving, data on overnight and not Wi-Fi, with email, texting, news, and tapa pulling data, am getting very good results. Looks like I can easily get 6+hours SOT.

Mine has been horrible since I got the phone 4 days ago. I lose bout 10% an hour or more. Not sure what's causing the drain. Phone stays slightly warm and google play services and android system are the top apps taking up the battery. If it stays this way, I will be forced to go back to V10 which gave me excellent battery life with same setup I have as S7Edge.
I am experiencing the same. I lose 10 percent an hour. I hope it changes.
Got 7hrs sot yesterday. With very heavy use.

Need more info please
I average about 3% an hour loss while at work (i.e. no wifi, bluetooth connected to Wear watch, and minimal SOT). So after 9 hours, I was around 73%. I'm getting about 5.5 hours of screen on time with playing games. Overall pretty good considering I have high-accuracy GPS enabled and no other power saving features enabled. I did disable a lot of app permissions for all the apps I have installed (i.e. I have ~250 apps installed) so not sure if that affected the battery life much.
I too am losing about 10%/hr. While I am impressed with the screen on time, I can get about 5.5hrs, the standby drain is crazy.

I don't know what you guys have running on your phones, but I'm not seeing anything close to that.
Mine dropped 15% in 8 hours overnight last night and about 30 minutes of screen time, with always on screen enabled. Which I consider acceptable. If I wanted to enhance that I could probably turn always on off, and enable greenpower to limit 4G when screen is off.
On St Patricks day (parade day), I was out for 6 hours, with 30 mins of screen time (just texting and pictures) and it drained from 100% to 92%.
The longest I've gone with out plugging it in so far has been about 15 hours, and that got me down 45% with 2 hours of screen on time. FAR better than what I got on my previous phone, the S5.

I'm getting an average of 7 hrs sot. This thing's a beast.
It's alright, 30hrs runtime, 11hrs SOT, 50% brightness mostly Web browsing (notice lightning+ 15%). I can make it work.
I got 12hrs of battery until it was completely dead on my initial 3 days of use. Android system was at 40-45% which seems high. Wiped system cache, disabled Nearby Device scanning, and turned off sync for a couple useless accounts and battery seems to have gotten way better. I will see how battery drain is overnight and tomorrow.
Side note: I always keep on Wi-Fi, Location, Bluetooth, Mobile Data, Always On Display. Disabling these features seems non-realistic for a normal user.
~1.5 days normal usage right now. I'm sure it could be 2 if I put it down more often, or didn't work in a bad service area.
Everything is always on. Location, WiFi, Bluetooth, and Auto brightness.
After a few days, mine is really really good. Hardly any standby discharge at all, and easily make it through the day and charge anywhere between 50-65% at night.

If you have wifi, throw your phone into airplane mode, then turn wifi back on. Wifi calling will be forced on and save you a lot of battery.
Not too bad. It's a lot better than the S5.
And how long it takes to charge is great too

I have literally next to zero standby drain. You have something installed that is doing that to your phone.
