I'm very happy with the battery life of the SGS4 (underclocked and undervolted).

With light usage around 1 hour screen on time, 30 minutes phone calls, auto sync google (gmail ~30 emails per day, contacts, calendar) and 3G only, I get around 4 days out of one charge. My SGS2 or LG O4X only managed 2 days with the exact same usage pattern.

[Galaxy S 4 General] Sparksltd:
No but im giving it a try!

Looks like a good idea.
[Galaxy S 4 General] MaKTaiL:
It takes around two days for the app to learn the way you use the phone. After the initial learning time the app starts saving battery. There is still one more day left to finish the learning process for me but I'll be back as soon as I can with the results.

I'm getting pretty horrid battery life compared to my S3. I'm a medium heavy user though only managing to scrape through 4 hours screen on time compared to the 5-6 on my S3 (after around 14hours on time). and yes I've wiped, checked wake locks though nothing out of the ordinary...

this is wifi on for majority of the time (same as my S3).

Damn... how do we permanently disable those useless background apps and make the system only open them when you use them? I tried stopping several background apps but after a few seconds they open up again. Apps like ChatON, watchON, Samsung Link, Story Album, etc. I think these are the ones responsible in drinking up our battery's juices coz' I can only get 3-4 hours tops on screen time.

When posting battery usage can you also day what kernel and ROM (and maybe any tweaks you used)?

I am trying to figure out the best possible combination. So far for me it seems to be CM-10.1 with stock CM kernel. Tried a few other kernels with undervolting and got about 50% less battery life.
[Galaxy S 4 General] chavxxx:
Are you using a extended battery or something? 8 hours?! Wow...

BTW, by changing the kernel, like perseus, will it make any difference on the battery life and performance?

Is there a way to permanently disable some apps from the running apps? Samsung Link, Story Album, S Voice are apps that i dont need. Also maps is running for the whole time my phone is on as well as software updater and i have disabled automatic updates. Also alarm clock widget is running way past the time i set the alarm. Can this be done without root? Thanks a lot. Sorry for the noobish questions.

after unninstaling all apps back to stock, i can say my battery lasts 12 hours with exchange sync and 1 hour of calls. Screen time; aprox 2 hours. Disaster.

Also 10% more juice for the battery :) 10% in my experience is equal to ~one straight hour of on screen, so it'll be the same as yours in 50%.

I got more than 8 hours screen time. This is with the original 2600 mah battery.

Rom is stock.

Kernel is perseus.

I achieved this by underclocking to 600 mhz. From what I understood is that underclocking to 600 mhz will allow only the A7 processor to work and that the processor operates at double the clock (1200 mhz), correct me if I am wrong. There was not much difference in the overall smoothness of the phone. Actually, I could not feel any difference. I did not check it with heavy games.

Most of the time I was playing TV series with MX player. I was connected to wifi most of the time.

I used greenify to hibernate some apps and disabled some stock samsung apps from the settings.

I dont get any benefit by trolling. i have the octal core variant (i9500 india). i unplugged my phone yesterday at 1pm (100%) and by 11 pm my phone was at 19%. My phone was on auto brightness, 8 minutes of phone call, 1 hour of web browsing, ran an antutu benchmark twice and thats it. My screen on tome showed 1hr 25 min. I was in my home where the network coverage is full and was on 3g all the time. The s4 overheats much more than any other phone.

Then you must have had mediaserver running, which is causing severe battery drain along with heat. You can see that in your battery stats

Not bad after the first full charge and with the sky go app running in the back ground for 10 hours sucking precious battery life even though I haven't used the app yet .
[Galaxy S 4 General] fade2green514:
From what ive seen if you're expecting to have the screen on 4+ hours just bring an extra battery, plug it into the wall awhile, or switch to battery saving mode. Honestly though, it looks like the battery life on it is amazing even though the screen is a bit of a hog.

You should be able to torrent a movie, watch it, and still get through the rest of the day with some texting and calling inbetween though.

Also people, can you state the brightness level that you've used to achieve those results? I'm sure someone with the lowest brightness might get better battery life than the guy with 50%.

Hello,

my i9500, everything stock, not rooted gave me a surprise.

After one week of usage, I tested the night drain for the first time.

At midnight, 100% battery. then unplug from the charger. Disconnect mobile connection. GPS/WiFI deactivated.

Waking up at 8am resulted in 92% battery left.

Well... my Optimus 2x had a 1500mAh battery and the i9500 has a 2600mAh. With the same procedure and settings, the 2x left 93-94%. Considering that the screen is off, it can not drain the battery more.

Where is the progress in modern technology in this case?

After that, I took it home for a full charge overnight. Its been approx. 3 days now since, and battery level is still around 70%.

I have been struggling with battery life since day one.

My S4 is a week old now and I have upgraded from SII (whose battery life was awesome).

Here are my stats (for this cycle I didn't use WiFi a lot as the internet at my home is out of service due to upgrading on the lines, so no need for WiFi)

Contrary to what I know and believe, WiFi drains battery a lot slower than Mobile DATA but on this device I'm seeing the opposite atm...

My Settings:

GPS =

off

Smart Stay/Scroll =

off

Brightness set to auto and throttle to 0

NFC/S Beam =

off

Air View/Air Gestures =

ON

Screen timeout set to 1min

Not using any task managers like GO task manager or battery savers like Juice defender etc.

Everything is stock.

I mostly have WiFi switched on nearly all the time and if heading out, I use H+ mobile DATA.

Could be I need to adjust to the bigger, brighter and vibrant 1080p screen, but still with a 2,600mAH battery, I'm disappointed.

The phone charges very quickly, I haven't seen any phone charge this quickly.

Any tips from your side?
