Angry galaxy s4 battery life.

I love my new s4 as I recently switched from an iphone. the best phone I have ever owned, good one Samsung! however, the battery life is rubbish. My iphone 4 lasted a hell of a lot longer than this. I can understand it might not last AS long as the screen is bigger and the phone is a lot more powerful and needs more battery power, however, I lose percentage ever 2-3 minutes and I don't think that's normal for such a great phone. can anyone give me ideas on how to improve the battery life? ( I've already drained the battery and recharged fully)

Can you tap the screen entry from that photo and show us what the screen on time is?

What brightness setting are you on?

Screen is always going to be your biggest battery eater. Lowering the brightness can help that tremendously.

Since the screen is larger than the iPhones, it takes a lot more power.

Coming from an iphone to android, i think you will always notice such a huge difference. I done exactly the same.

Dare i say it but ios is a lot more power friendly as it only has to work on 3 different phones whereas android has to be a lot broader in its approach.

There are multiple different things you can do to conserve power like make sure your brightness is as low as possible. Switch the screen off manually when not using it instead of waiting for it to sleep.

Facebook is a notorious battery drainer, it might be worthwhile deleting the app and creating a shortcut on your home screen to the website if you use it a lot.

All in all though, what you are experiencing is perfectly normal. You'll get used to it eventually though! On the plus side though, you can swap out you S4 battery, couldnt do that with an iphone!

I'd like to add, make sure you have all the S features off if your not using them. Tell us what your own screen time is as well. If you play a lot of games, that will drain the battery pretty fast as well. For me using around 3+ hrs of on screen time using auto brightness, I get 12 to 14 hrs with around 20% battery left. All my S features are office except Smart Stay.

I always got good battery life, running the Google Edition ROM it is even better. But I havent used my phone much over this battery cycle, a few calls and texts, checked facebook a few times, but I just got a new tablet I've been playing with.

I went from an iPhone to the Galaxy S4 and I find I get at least double the battery life out of the GS4, I also have brightness on max and I don't use any power saving apps

Wife's S4 battery was at 66% last night (unplugged about 14 hrs) and my HTC EVO LTE was 52% (unplugged about 14 hrs). The difference, however, is that my wife's S4 had been used much more!

Have my S4 less than a week so I will reserve judgement for a while.

That said, this is my 6th Android phone and my work issued iPhone 5 (and 4S before it) just lasts much longer with heavier use. I wouldn't buy an iPhone with my own money, but the battery life is simply superior.

I have never gotten better battery life than with this S4, coming from a DInc and a Rezound. I have most of Sam's air gestures and moves and such turned on. Of course I'm a light to moderate user when I'm home, having 50% of my battery left at the end of the day. When I'm travelling and using it heavily, I still have enough to do what I want through day and have 30% left.

I seldom get below 50%, and when I do it's typically because I didn't charge it the night before. I do, however, almost always connect the phone to power while in a car, but at the same time, I am also typically using Navigation and AmazonMP3 at the same time, with the screen on, so charging isn't that rapid while in the car.

I use the Zerolemon extended battery, so I usually get 2 days out of my phone. The stock battery with all the extra samsung features lasts me 12-14 hours of moderate use which is fine.

17.5 hours on battery, that sounds like a full day to me (you HAVE to sleep sometime... ). *I* would say that's acceptable. To me, if I get through the day without having to recharge then everything is fine.

Your phone was awake a lot during that time, if you weren't actively using it you might check to see what's keeping it awake.

This app will help you determine what's keeping it awake.
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector

This app will tell you whether or not your CPU has been sleeping. If it's not spending lots of time in 'deep sleep' (when you're not using the phone) then something is wrong.

Best thing to do is don't worry about it and charge it when you can. When I first left the iPhone I was stressing about the same thing. Finally I just gave up. You have to understand how much more resources the Android OS uses compared to iOS. Widgets, larger screens, and more bells and whistles than iOS could dream of is running in Android. iOS will always have better battery life than an Android phone unless you have the RAZR HD MAXX.

some people have told me because I'm that used to being on the apple platform that I can't get used to the battery on android so I guess that's why haha, but hey at least I don't have a dreaded iPhone anymore.

I can't believe nobody has told you this, but the biggest reason your iPhone 4 had better battery life is because it is a 3G phone. Since your S4 is 4G, it will use more battery due to radio switching and the sheer power demands of the 4G environment! That is the nature of the beast. That extra inch of screen size will have a big effect as well.

I'm a light to moderate user and usually have at least 60% left by day's end! So, as was stated before, buy yourself a spare battery and swap out if/when you run low (can't do that, Apple!).

Fire up that S4 and don't look back!

Here's some screenshots of my phone. I don't use it much and have all the novelties off. I use auto brightness and a battery saver that allows you to set a night schedule for mobile network connectivity.

Coming from a RAZR MAXX, the shorter battery life is a shock, even though I expected it. I have chosen to order a couple of extra batteries and get an Otterbox Reflex case, primarily because it will be easy to remove the case for battery switching.

Their screen time was only like 3 hrs or so for two days. I think the minimal screen on time is 2 to 4 hrs for the average user. (Mine is 3 hrs.) I have found that the screen and playing high intense games drains the battery the fastest. There are a lot of other features you can turn off to save battery as well.

Irony: Yesterday I had my first battery drain. Google Services consumed 60% my battery before I caught it at 30% battery level. I restarted, but it's doing it again today. I have no option to stop it or report. The only thing I can do is turn off the location reporting, which hasn't been a problem in the last month. I have always left my GPS on. A friend of mine said yesterday that Google Services has also used an obscene amount of data on his phone.

For those who are having battery life issues, you may want to download "Battery Guru", free in the Play Store. The app is written by Qualcomm, and is specifically designed to optimize battery life on devices with Snapdragon processors. I have experienced a 20% increase in battery life using it.

On that note, I wonder if anyone has experience with a pre-iPhone 5 and iPhone 5 in terms of battery life. I know asking in an Android forum isn't the ideal place, but just wondering. iP5 vs. iP4S or lower would have similar issues, namely larger screen size and 4G vs. 3G.

I just activated my SGS4 and haven't transferred my apps and data from my Droid 3 yet. So I'm just using the SGS4 mainly to text and surf. I haven't even made a phone call yet. (Who uses a phone for making call these days? ) I also noticed that every few min. of surfing would decrement the battery by 1% that the thread starter mentioned. If I extrapolate that and assume linear battery consumption, that would give 5 hours of surf time (screen is auto-brightness). Seems reasonable.

My battery was already about half charged when I got it and I wall-charged it to full before using it. I fully drained it by yesterday morning and it took over 7 hours to charge it by USB. That's way longer than it took my D3. That said, since the S4's battery is about twice the capacity of the D3, I guess it'd take twice as long since USB can only push out so much power.

One day, I'll use my Kill-A-Watt to see how many watts it takes to wall-charge my phone. My D3 took a few W, pretty much negligible.

As a point of clarification, Google Services had used 60% of charge that had been used, not 60% of the total battery charge. In this instance it used 60% of the 70% that had been used, or 42% of the total battery charge.
Which is not to say that GS hadn't been running amok, it had.
I'm just trying to help folks understand what that screen is trying to tell them (which is not to say that YOU don't already understand. )

When I first got the S4 the battery life was dismal. (Some of that was my continual playing with it granted) I am talking about 3-4 hours before a recharge. After several recharging cycles, and normal use (normal for me is several voice calls a day, heavy navigation usage, pandora streaming and constant email/facebook/text) resuming it now lasts me from 7am until about 9pm. My biggest problem was (and still is at times) poor signal coverage at work. That has settled down a bit, but when the signal is poor I lose about 20% an hour. I even have some of the gestures turned on because I like playing with them. It is my opinion that signal strength is the big variable that affects battery usage.

is it OK to drain your battery? at least once or twice? been using my s4 for less than 3 weeks. maximum battery lifetime is about MORE THAN a day but less than 2 days. Been using it for sms/text messaging and wifi (for at least 5minutes every night) since i got it, haven't tried to drain my battery yet. btw, it is not rooted

I've seen this with a few other people! What the hell is the deal with Google services being at the top of battery usage all of a sudden in the last 24 to 48 hours????

Anyone have any ideas?

I even have some of the gestures turned on because I like playing with them. It is my opinion that signal strength is the big variable that affects battery usage.
This is true.

You will also get better battery life while connected to wifi as opposed to using your carrier's mobile data. (Generally speaking, of course )

The best way to get maximum battery power to flash a custom ROM. I use Liquidsmooth on my S4 the battery is so much better then the stock ROM.

Same here, no issues, and screen is set to max.

Not to hijack the thread, but why would the two of you (you and astroboi82) both have the screen brightness set to max? I've found the automatic brightness setting on the S4 to be really good at making quick adjustments when necessary.

It takes me about 3 hours to fully charge my phone from empty using a charging cable I used w/ my old phone and if the phone is turned off. Some say it's faster using the white cable that came w/ the phone, but I haven't tried that yet.

Apple battery life may have been good in the little i4, but it's not in the i5:
Samsung's Galaxy S4 scoops the iPhone 5 on battery life

I'd guess the i5s would be worse given the bigger processor and little or no change in the battery.

I use Juice Defender on my S4 and it increased battery life dramatically for the way I use my phone. Also strongly agree that signal strength makes a big difference.

The charger that came with the phone is the fastest charger I've ever used. Not sure if the cable is that important, though. Most likely it's the charger itself. I've heard it's 2 amp compared to 1 amp for most other chargers.

There's another thread here where I learned something new about voltage drop. I usually think of it in higher voltage, such as generator runs, but it turns out you can have significant voltage drop in 5 volt over just 3 feet if the gauge of the wire is not sufficient. As I recall, you should have 24 gauge wire, where many USB cables are 28 gauge.

Anyway, not terribly up on battery charging, but I would suspect a voltage drop would significantly impact charging times.

You are correct on this. I've tried using old chargers, that are less then the 2.0 amp on the S4 stock charger. (They take like 3 hrs from about 20% battery left.) I can charge my phone from 10% battery left to 100%, in sleep mode, in just under 2 hrs. Considering how big the battery is, the stock charger charges really fast.

Obviously we're all gonna get different results, I'm a medium-to-heavy user and have yet to have it die before the day is out. With average use it usually makes it halfway into the next day

Screen brightness is your biggest issue, I have mine set at around a third. At first it's a little dark but you get used to it, and turning it back up is too bright

If it's a regular problem you might want to look into either a spare battery or a bigger one. A spare is better if you're only occasionally squeezing more juice out the phone, whereas an extended battery or case is better if it's a regualar thing

I see, so the OEM cable cuts down the recharge time by 1 hour from 3 to 2. I'll try that out myself on a night when I drain my battery fully to 0%.

Its not a good idea to drain your battery to 0%. If you don't have access to a plu during the day, you might want to invest in an extra battery to swap out during the day. (It will save your battery in the long run.)

I use my external Astro 3 to recharge my S4. The original charger requires 2 hrs 20 minutes to recharge from 10%. The Astro does it in only 1 hr 32 minutes. Designed to charge up to three smartphones or a tablet and two phones all at once, it's great to have such a compact solution to take with me.
