    Hi there. ok so today i bought my self a brand new s4 (3g intl standard version). I have just upgraded from an galasy s2.

    Before I get to the point i want you to know about the battery life on my s2. When i had my s2 running Android v2.3.5 The battery life was amazing like 5 hrs of moderate use would result in a drop of around 10% of the battery.

    A year later, when jellybeans for the s2 was rolled out, the battery life immediately dropped drastically. It seems like a lot of the energy was being wasted as a simple web browsing session would considerable warm my phone up (not the case in v2.3.5) A 5 hour usage would result in a drop of atleast 30% or even 40%

    NOW the thing is, this same battery drain issue I am experiencing on my NEW s4. A simple web browsing session is considerable warming my phone up and a game would make my phone hot :mad:

    So my question is. What is going on?? Is there something inherently wrong with android jelly beans as i have experianced this one two phone form the same brand. Are you experiencing something like this with your s4 where the phone always warms up when doing light task like web browsing?

    Have you tried using a different browser? I've not had an issue like that with the Chrome browser.

    Generally, the battery will need few charge cycles to achieve full potential. So it will improve over time.
    Secondly, get rid off some of the SYNCs. Like Google Auto-Backup, which backups your phone's gallery to G+ private photo gallery.
    Turn off location history and location reporting. You might not want to kill the service entirely for apps which might need it (location based weather widgets). But for apps like maps, G+, facebook, instagram etc, why not...

    Unless you really want to report your whereabouts to every app, then disregard my comment :)

    The location reporting and history can be real hog. When I turned it off, it instability improved my battery life.

    Screen illumination is also one of the biggest battery consumer, you might want to introduce some dark or black based theme. The amount of power the display consumes varies significantly depending on the color and brightness of the screen. From 0.3 watts showing white text on a black background, to more than 0.7 watts showing black text on a white background. AMOLED will turn off any black pixels, making it more battery friendly.

    A full black might introduce some smear effect when scrolling fine, white text. But as soon as you make it 98% black, it will go away.

    I use whatsapp a lot, naturally, screen ON for extended period of time. So for that purpose, I fully customized my theme, to keep the screen illumination to minimum. Example:


    As for the heat. I get my phone fairly warm, but nothing unusual or more than my S3 and Note 2. Unless I watch movie (full length film), then yes, it gets noticeably warmer. Also, I live in tropic, where ambient temperatures are high all year around, so this will contribute to phone heating up a bit.

    I do monitor the temperature now and then, through my lock-screen widget and the hottest I ever got, was 43 degrees, after playing a movie for over an hour. But if your phone gets to 50 and above, I would take it back to the service.

    You could always reduce the temperature by limiting your phone's services. If you play game or watch movie, turn off whatever is that you don't need. Like wifi, gps or bt. AirView or other of motion/gesture related. Avoid long web surfing in bright places, where you need to max up your brightens to see the screen. Just common sense kind of things.

    Just out of curiosity, would you be so kind to share, what's the temperature that your phone gets to ?

    regards and good day :)

    Part of the reason I suggested Chrome above is I don't believe the motion/gesture related services work with Chrome. I have no idea how much battery those services take because I have them turned off.

    I used stock ROMs on both my S2 and S4 and the battery life is slightly better than the S2 but there isn't a great deal in it.

    My S2 used to get very hot to such an extent that I sometimes started to worry that it was going to get damaged and turned it off. My S4 doesn't get anywhere near as hot.
