Battery life when screen is off - Verizon Samsung Galaxy S 4

How much battery does your phone use bring in idle? Mike seems to lose about one percent every two hours. Does this seem normal? I have almost everything off, wifi, bluetooth, Google now... Stock phone, no root or custom rom.

I haven't really noticed because I can't leave my phone alone long enough. However if I don't play at a lot of Tapped Out going from 7:30am to 8pm I'm often at 50%. That is with GPS off and WiFi on using it for maybe 10mins every hour for email or quick google searches.

I'd be happy if my Galaxy Nexus drained at that rate in deep sleep.
My past few phones, including this one, that is normal.

Thanks for the replies everyone. I'll try using power saving mode overnight too, to see if it helps.

That's great, when you compare it to all the other major android manufacturers out their. You want to improve on that? What kind of phone are you coming from because you should be using that as a base unless it was a basic phone. The only way to improve on that would be to use the built in battery saving feature and/or download a third party program so that you can limit how often you phone connects to Verizon's network.
In my opinion, you'll get better battery life by staying connected to wifi as oppose to staying connected to Verizon's network.

Cool, thanks for the reply. I'm coming from an iPhone 5. I really never paid attention to how fast that phone drained overnight, but I could check. Just wanted to see what everyone else was getting.

Will the people that get awesome battery life share what they are running?

I've tried a bunch of different combinations but I have gone back to GB every time. I don't even care about features anymore I just want to get the most out of my battery life. If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.

I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:

Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:
Latest ruu-cleanrom de 1.4-take it easy on the apps and widgets!

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.
http://www.amazon.com/dp/B0055OTNK4/ref=pe_175190_21431760_C1_cs_sce_3p_dp_1
Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.

Batterylife comparison: Stock VS CM9 VS CM10

Hi all
This is my first post, so let's hope I've gotten it right and am abiding by all the rules and the n00b video. And yes I did search for a good 10 minutes about batterylife and battery before posting and didn't find anything relevant.
I've recently swapped over from Apple iPhone and I'm now very much enjoying being on Android. However batterylife is a big concern for me, as on iPhone I could go 2-3 days without charging and now I can barely make it home from work and I definately have to plug it in before dinner. And yes this is with me closing down applications, wifi when not used, bluetooth when not used, running latest kies released PHONE:LFB firmware and so on.
So my question is... how is your batterylife after having rooted and installed a custom rom? The one I'm thinking mostly about using is definately the new Preview 3 (or perhaps wait for 4 or 5) of CM10, that XpLoDWilD is working on. Does anyone have any experience with the batterylife before and after?
Thanks a lot for any help you can provide! :highfive:

That's very weird. Are you international or a US S3? I easily get 3 days battery, very easily. Perhaps try turning off useless stuff like bluetooth, gps, wifi, etc when you're not using them. Turn off push email and other useless crap. See how it goes then?
I still have the stock ROM, usually 3.5 days battery before it gets to 10% and i charge. I'm going to go to OMEGA rom soon though.
I have tried almost all custom roms out there. And I can easily say the battery life is not any better if not worse on custom roms.
Stick with the stock rom. I would however recommend flashing a custom kernel like speedmod or phenomenal. They definitely give you that extra juice you need at the end of the day. The idle time and screen time has increased for me 10 to 20 % compared to stock.

I'm using the international version. I did turn off bluetooth and wifi, but not gps. Will try that aswell. I have manuel mail check every 1 hour, but will try to set it to 4 hours.
However from what I read in the reviews on GSMarena and other sites, it's quite normal to only get 1 day worth of battery.
Description of a pretty basic day with the Galaxy S3:
I usually unplug mine at 6 am, with wifi and bluetooth off and screen always on auto brigthness. Then at 7 am i turn on bluetooth for my earphones and bike to the train station and browse the web and such for about 45 minutes in the train. When I arrive at work it's usually around 80% battery and I turn off bluetooth. Then I'm at work from 8 am to 4 pm and check mails, texts, calendar and possibly make 1 or 2 short phone calls. At 4 pm I think the battery is often around 40-50%. Then again on the ride home I use the same, so it's usually around 20-30% when I come home. I then usually turn on wifi and play a couple of games, or watch some Netflix on it while I'm doing some other stuff or attach it to my stereo and play so music from Spotify on it. At 6-7 pm it's usually beeping at the 5, 10 or 15% marker for more power and wants me to plug it in to a power source. If I try to wait till I go to bed, I usually end up having it automatically shut down from lack of power.
I'm wondering if this seems normal or if perhaps my battery is faulty. From the review at GSMarena it seems quite normal and that's just the way Android is. They even gave it a good battery rating inspite of saying that it would only last them a day.

Okay, thank you for your reply
it all depends on the usage i have an iphone 4 as well and i have to charge it by the end of the day (at 10pm). So it dpends on what you do with your phone if you use 3g all the time thats not gonna last long if you have syncing on all the time and gps that wont help...if you just let it idle then you can get 3 days uptime with maybe 1 hour screen time.

My basic day is charge the phone at around 8pm, unplug at 10pm. I never charge overnight it's pointless (not that i think it'll hurt it). Wake up battery is usually around 95% after my alarm goes off. Brightness is about 60%. I don't browse the web very much, and I don't play many games, let's say 1 hour of web and 1 hour of games/videos/music per day. Maybe 1 hour of maps too. Mostly though, I text message and phone call.
I don't think yours is faulty, i think it's quite normal, it seems like you're a heavy user, I'm a light user. If I used my phone as heavily as you did i'd be happy with 1 day of battery.
One day of charge (the battery being at 20-40% at the end of the day depending on the usage) is quite normal.
I've found CM9 with Siyah to give the best standby battery (1-2% drain per hour with 3G and Sync enabled) since it's very lightweight and has no battery-draining bloatware other than what you install.
CM10 is still too new and unfinished to be battery-friendly, it's not that bad though.
However sometimes it will chew the battery for no freaking reason (at least I cannot found any) and the CM9/CM10 stock kernel is not that battery-friendly on active usage. No Siyah yet =(

No way is that good man, that means that if you leave it on standby alone you lose 25% per day. 0.5% per hour would be good/normal IMO.

[Q] Battery consumption

Hey,
I could not find a thread like this via the search bar, so I am opening one up. How much battery does your stock S3 consume by just lying there? I am losing about ten percent overnight, which seems a bit too much for me. Is that normal?
Thanks!
Wait till you get about 70 percent discharge overnight then you'll have something to worry about.

If you searched or read the multiple battery threads then you would have found that yes it is normal .
All depends upon what running .

At night I turn off wifi and data, my battery drops 3%, with data on and wifi off about 5% ( about 8 hours)
Based on reviews on the net it is possible to get it drop 6% in 16 hours with data and wifi on, not getting to this myself but happy enough.

It is very normal for Stock rom to consume that much battery.. However you can save more battery by going into Wifi > advanced > Keepy wifi on during sleep > Select Only when plugged in... Plus disabling wake up commands such as the ones for S Voice, or Google Now can increase battery life upto a great extent.
Also try turning off location services for apps that you don't use that often or the ones that don't really require location services that much.
I had 10 to 15% drop the night, after installing Chrome (because of google sync issue)
but after removed it.. im back to 6-7%
Anyway Dolphin is better
I can only say from memory ...

I can only say from memory - a very clean S3 should get at most 2-3% discharge overnight (even with WiFi, data, BT and GPS started). That might no longer be achievable once you have a number of programs that interact and keep the CPU from staying into deep sleep.
Currently I am seeing at most 1-2% with my configuration - but that involves closing the 4 above before going to bed.(and to get to that point I had to drop a number of programs that were bad in this regard).
Do your own tests with that - look around after BetterBatteryStats.apk or something like that!

Can I ask what your current configuration is?
I am currently running Omega v32.1 with the stock kernel.
I hardly use my phone during the day as I am at work for 12 hours, maybe send a few texts. 3g and sync are always on
I take it off charge at 5.30AM and when I get home at like 8PM it is down to less than 10%... and thats not even heavy use.
I have calibrated the battery using that batterycalibrate app for root users..

'keep wifi on when screen times out'?

what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.

Wi-Fi connected banner at bottom of screen

Is there any way to prevent this banner (picture attached) from appearing when Wi-Fi is initially connected? I use Juice Defender to disable Wi-Fi when the screen is off and it is very annoying to have this pop up every time I unlock the phone.
Every time you unlock the phone? Mine only does that on actual connects and thats it. You must have it set to turn off wifi during sleep? If that is the case... some dev will have to find where that is burried at in the OS. Easier thing to do is let it stay connected. Better on your data anyway and if youre on unlimited still why bother with wifi at that point?

I purposely use Juice Defender to turn off data and Wi-Fi when the screen is off. Both turn back on when the phone is unlocked, which is why it appears every time.
ahhh on rooted phones with custom roms i don't recommend Juice Defender. It's usually more trouble then it's worth and more times then not ppl say it uses more resources then it saves (battery). And why data when screen is off? Just curious since you'll only ever get just texts and calls then and miss everything else notification wise.
My guess for what you're asking for is someone would have to make a special effort to do it.

I would suspect that this may be doing more harm than good for your battery life. My battery will last much longer using wifi if available. Maybe instead of using Juice defender to turn off wifi, you could try using the "wifi off during sleep" option that is built into the phone. I think it will accomplish the same thing and it may disable the pop-up within the system.

I tried this option but it doesn't even work for me. Wifi stays on.

I noticed that sometime with this phone (and the S3). "Off" doesn't seem to mean "off" anymore. My phone could mysteriously discover a known wifi network and suggest connecting to it while the wifi is supposedly turned off. If it is truely off, then it wouldn't know there is a network available!

I find that turning data off too dramatically reduces standby drain. It automatically turns back on if an MMS comes in and periodically turns on to receive other notifications. Juice Defender has worked pretty well for me and I'm on CleanROM.
I'm on CleanROM (1.0 still) with no apps to help with battery and i get .25% battery drain while idle (so thats 4 hours before i lose 1%) and 10-11% battery drain per 1:30 min movie with full brightness with WiFi on. How much better can the battery get on a stock battery? I bet you with Juice Defender you don't even get close to that simply because it actually has to run in the background while phone is idle to do it's job.

Without Juice Defender I'd lose 1% every hour and a half on standby. Since installing it, it has been much better.
