[Galaxy S 4 Q&A, Help & Troubleshooting] fade2green514:
i personally am not expecting the battery life to be much better than the galaxy s3's when you use it more often.

-it'll last way longer when idle!

however, the 3g speed is way faster in the s4 than the s3 so it depends on coverage area.

also, it has a newer wifi type which may use more, or less battery, who knows (AC not just 'N')

it has a faster processor, which when idle could use less, or more.

the 5" screen is slightly larger as you all have said, however it has MORE than twice the amount of pixels. the screen itself will not be the only factor when it comes to display usage. you also have to remember that the 1080p will tax the GPU more, which even in computers often times consumes the most power out of any of the chips in a computer.

me personally, the battery is going to be a huge upgrade from my droid 3's 1500mah battery life lol
[Galaxy S 4 Q&A, Help & Troubleshooting] mr_sock:
I think so because websites usually have white background. I know there's special websites for OLED screen (e.g. black screen google, bgoog.com) for this reason.

I prefer to get replaceable battery so I can potentially use my Galaxy Nexus for many many years, if not for a phone then for mp3, GPS, car blackbox, camera etc.
[Galaxy S 4 Q&A, Help & Troubleshooting] tuxonhtc:
Ahh yeah. My doubt was whether the drain would be equal to LCDs when it comes to whites and far less when it comes to blacks, but looks like OLED might do slightly worse when it comes to web browsing for that reason. And I do use inverted mode during night and that helps too, should theoretically fare way better than LCDs then.

Agree re: replaceable battery, obviously.

[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
I am very impressed with the battery life on the I9505. I'd call myself a heavy user yet, despite this, I take the phone off charge aroung 7am and still have between 30% and 45% remaing around midnight when I put it back on charge (I charge my phone every night). So that is no more than a 70% loss in 17-18 hours. Anyone expecting more than this from a 5" 1080p device needs a reality check.

First week.

Around 22 hour with 3G, I got 5 hours screen.

Compare to my last phone (LG 02x and Nexus One), this is already better.

May be it will be better in second week. Today I flash Wanam 1.1 kernel. He said there are some battery tweak included.

Or an HTC One. My previous phone was the Razr HD and the HTC One battery lasts just as long with my usage. And the HTC Onc has only a 2330mAh so....

Bottom line.. there are choices. Silly Samsung plastic toys belong in the toy box.

[Galaxy S 4 Q&A, Help & Troubleshooting] msavic6:
Plastic toys belong in the toy box...? People are honestly getting really pathetic with this "plastic" argument.

[Galaxy S 4 Q&A, Help & Troubleshooting] xdracco:
Hmm. sounds like someone isn't paying attention. The HTC One hasn't sold due to marketing. Samsung dumps billions into advertising. And it looks like they reached the toy box audience.
[Galaxy S 4 Q&A, Help & Troubleshooting] msavic6:
The HTC One had its period of time when. the S4 was not even released and all the press was drooling over the One. They had enough marketing happening just from the Press, but guess what, people have good memory and they remember phones like the One X and they don't want anything to do with that company anymore.

Anyway this isn't the place for this discussion.

I think battery life for this device is very good. That being said I wouldn't mind my phone being a couple of mm thicker if it got me even better battery life. I think the phone is too thin as is. I wish someone made an extended battery of about 3500 mah that didn't have a hideous battery cover.

[Galaxy S 4 Q&A, Help & Troubleshooting] :
I'm using a combination of battery saving apps and tweaks. I'm able to get by a day and a half with moderate usage, with a drain of about 4-7% per hour. The apps are as follows:

Greenify - I Greenify any app that has background services and that connects to the Internet with it ie. Facebook.

Deep Sleep Battery Saver Pro - I've got my schedule set to connect every 5 minutes for 30 seconds at a time.

AutoKiller Pro - I activated all the battery saving kernel tweaks, I can't remember them all.

Lux Pro - I have my default brightness linked to quite a bit lower than the default levels. I prefer it this way and it saves my battery as well.

I've also disabled all the fancy and arguably useless air functions of Samsung, except for smart screen and smart stay. The only motion gesture I have on is the one to answer calls with a wave of your hand.

I've also uninstalled all of Samsung's bloatware, namely Samsung push service and Samsung link. These apps were all purged using root privileges. I've also disabled the media scanner as well.

Hope this helps someone.

After using the phone for +5 weeks I'm very satisfied with the battery performence. On the average I get 24 hours from 100% to 1 %. I never got it below 20 hours! Which means that I never have to charge it more than once a day which is very convinient. Most of the time I do it while sleeping or while busy with something else. After all it needs less than 2 hours to fully charge from zero!

Below are some photos of the results I get (24 hours). My normal usage; data on all the time and wifi whenever available. Brightness set on the adapt option and air gestures are all on! I don't use the phone for gaming, but I do a lot of browsing, email and texting.

Coming from my previous phone (S II) this is a very impressive performance and I'm very satisfied.

Heyy guys, just wanted to ask why my galaxy s4 battery dropped 7% overnight even on airplane mode, It was 93% before I went to sleep and I woke up next morning it was 86% (I slept for 8 hrs). No apps were open and was in flight mode, any ideas on whats happening? Using stock rom btw, not rooted....
[Galaxy S 4 Q&A, Help & Troubleshooting] jimmboonline:
Something to try...

1) drain all of your battery untill phone shuts down

2) after your phone shuts off turn on and drain battery until phone shuts down ( repeat until you are unable to turn the phone on- this step is very important because we need to drain the battery competely-ish (to drain the battery to 0VDC would create a paperweight ))

3) take the battery out and wait 5 seconds or so and put it back in

4) while the phone is off, Charge the battery to 100% [===}

5) when the charge is 100%, take the charger off then power on the phone

6) after powering on the phone charge again to get 100% again

this should calibrate your battery

I think i should do this too as i am only able to get 4 hours of screen on time.........
[Galaxy S 4 Q&A, Help & Troubleshooting] Metallice:
No no no no no no no!

Anybody reading this... DO NOT DO THIS.

There is absolutely not point. I swear how long will people still think that lithium ion batteries need "calibration"?

This will only decrease your battery life as full drains hurt lion capacity.

If you want to maximize lion battery life keep it bouncing between 60 and 90% capacity
[Galaxy S 4 Q&A, Help & Troubleshooting] jimmboonline:
We are only trying to help the android comminity :)

I totally agree, that If you want to maximize lion battery life keep it bouncing between 60 and 90% capacity as this is their "Happy place"

A fully charged all the time battery creates a much more acidic environment that can cause corrosion and hurt the longevity of the battery.

I agree a lithium ion battery drain to 0V will cause nothing but a poor paperweight, it is not recommended. bringing the the battery to the phone's safety off voltage say 3.1v 5-10 times in my opinion will not cause a decrease your battery life as i have a 1.5 year old battery that maintains an excellent charge still.

I have not tried this on my SGS4, however when switching kernels and roms on my SGS2 I have noticed funny things happen to my battery(UNHOLY battery drain, 40% -> 55% then down again), and the method above has always fixed the issue.

If it doesn't work, don't keep doing it expecting different results. :silly:

below is my SGS2 that i have done this on and the results speak for themselves. (stock battery + airplane mode)

If you don't want to drain your battery till your phone turns off, skip steps 1-3.
[Galaxy S 4 Q&A, Help & Troubleshooting] Metallice:
Fair enough. I kept my spare gnex battery at ~90 for this reason. Although, I still don't see the point of draining a li-on battery though. As far as I know, li-on batteries can't become "mis-calibrated".
[Galaxy S 4 Q&A, Help & Troubleshooting] cinnabar:
I generally keep my battery charged when it hits >30%. I still have no problem achieving really good battery life. Currently I'm at 29%, 22h 25m with 3 hrs of 'time on'. And that's stock ROM rooted. It actually got slightly better after a downloaded the AT&T update (21mb update that came out a little while ago). I used to own a GS2 and I could achieve similar results using the same battery charging technique. However, in that case that was only after I had rooted and put new CWM and ROMs on it.

Battery in standby

Hi,

I have the i9505 version running stock 4.2.2 with latest updates.

I have it just a week but I was curious about the battery and it lasts quite well, when it comes to actual usage(which is great) BUT I feel the phone could handle standby time a lot better.

Overnight it drains exactly 8% of battery . And that is during deep sleep. My setup is simple flight mode and wifi on (sleep policy set to always) and that is all. No apps running in background no sync etc.

I Installed battery monitor and found out that it drains the battery at 50mA. What is STRANGE that actually if I turn of wifi it is worse and if I do not turn flight mode on it drains at 36mA. Which is strange but how are your GS4 compared to mine in standby ?

I had an S2 before and after flashing many ROMs I usually got about 2% drain overnight.

IF someone says that it is more powerful phone that should drain more quickly even in standby then lets do a math.

2% of 1650mAh is 33mAh drained overnight (8hrs) which is about 4mA per hour

8% of 2600mAh is 208mAh drained overnight (8hrs) which is about 26mA per hour

So the standby uses over 6times more energy ? The problem is I am a light user so I usually get around 2 days out of my S2 sometimes 3 so I expected to get 4days of my usage (some calls, sms, whatsapp, some internet, and light gaming) but so how things are now I usually get around the same battery which I could get on a 2years old phone which is absolutely ridiculous.

I'm quite happy with the battery performance on my i9505. I usually average between 21-30 hours with 3-4 hours screentime, I try to put the phone on charge once down to around 30%. Im running stock rooted firmware with a fair bit of bloat removed. Daily usage does not vary a great deal with Wifi on constantly (except around 11pm to 6.30am), occasional 3G use -switched off if connected to wifi, not much GPS use if any, location services (wifi only) on, not a great amount of calls, mostly browsing XDA, Facebook, twitter, Google+. I have most of the sensors disabled (switch on to use and toggle off again) except for 'Motion'. I keep the screen brightness on manual and usually have it around 25-50%. I have checked better battery stats to see if there is anything sucking any extra power that could be tweaked, but there didn't appear to be any wakelocks over the 2min mark with most a matter of seconds.
[Galaxy S 4 Q&A, Help & Troubleshooting] Proteus55:
Battery life is very subjective. No 2 persons in the world will get the same battery life.

Coming from a HTC Desire HD with 1230mAh battery, I find S4's 2600mAh battery pretty impressive. Finally I no longer have to keep switching off data and "Greenifying" everything for fear of the phone running out of juice unexpectedly mid day.

Having said that, you'll almost never get the same battery life everyday. Some days I play a fair bit of games or watch you tube while trying to fall asleep, so naturally, I'll have "poor" battery life. On the other hand, on busier days when I can't really "play" with the phone and sneak in some Flipboard, Facebook and Feedly during my breaks, I get close to 20 hours with 20% remaining, sometimes more, with 4G constantly on throughout the day, no wifi, no Greenify.

Bottom line is, it's down to your usage. There are many other alternatives. If you need more juice, get an extended battery or a case with built in power bank. If these options cramp your style, get a phone with a larger battery, like the Note series or Razor Maxx.....or better still....get a Nokia dumb phone. They have truly amazing battery life and just life in general. My old Nokia which I got in 2006 is still alive and kicking today. Beats my SGS4 any day and I've never had to replace the battery, ever.
[Galaxy S 4 Q&A, Help & Troubleshooting] diwad:
Well I do not know but I was not mentioning battery life but the standby. I am curious about yours. Most people turn off cellular and wifi and put it in flight mode or leave it just so. So the standby SHOULD be mostly the same.

As I said I get around 10% drain over 8 hours of doing absolutely nothing with almost everything turned off. On my S2 I got around 1-2% drain compared to 8-15% it is indeed a BIG jump if you consider that the capacity of the battery has ALMOST doubled. So basically it is around like 15times more in standby.

8 hours of sleep then 16 hours of usage and I am down to zero. With around 3 hours of screen on time .

Well some may think "that is quite good " but no. I barely use 3G mostly on wifi, I have sync off location off etc. SO with this light usage a day is very low as I can get this with my S2 quite easily with a 50% left.

The question is WHY is this happening ? The first day I Had the SAME usage as described even heavier as you could imagine I got the phone so I was playing around and I got a day of usage with 6 1/2 screen on time ! And i was happy with it. Then I updated it (350MB update) and it went down the road...

I could post some screenshots of better battery stats but I cannot find the culprit myself.

Anyone willing to help ? :)
