    Default S4 battery life

    How is the battery life on the Galaxy s4? I have a Galaxy 2 and the batteries only last 4-5 hrs and I usually go thru 3-4 a day. I was thinking about upgrading to the s4 but wanted to check into this first. Also do they use the same batteries as the s2?

    The Galaxy S4 uses a 2600mAh battery while the Galaxy SII has a 1650mAh battery (1850mAh battery with a built-in NFC antenna if you have the T-Mobile Galaxy SII), so no the two devices use batteries with different amounts of power which basically kills any chance of being able to swap batteries between both, assuming there was even a chance in the first place.

    As for the battery life on the S4......//with my experience using the international variant of the S4, it lasts pretty much 2 days for me with light use and about an entire day with moderate to heavy usage. Of course, the YMMV rule still applies.

    properly not.
    on amazon, I have seen the Onite battery for Galaxy s2 is 2200mah
    but Galaxy s4 is 2600mah, also 3600mah with a back cover is avilable

    I was merely referencing the stock OEM batteries that both phones come with, not the higher capacity aftermarket ones available.

    Battery life is extremely poor on an unrooted stock Galaxy S4.

    My battery lasts for about 9 hours of constant use, and it's takes about 2 hours to recharge.
    I'm more than pleased with the battery life of this device.

    I would agree with the above post and I am probably a heavier-than-normal user. I get about 10 hours out of a full charge before I think about plugging it in. The wall charger will give it a full charge in less than 2 hours and in 30 minutes on the Samsung car charger, I increase the battery by 15%. I am extremely impressed by the battery, especially coming from my HTC Amaze that gave me 3 hours.

    I have found the S4 battery to be about 10 hours or a full day's use. However, I found a easy fix and/or backup. I purchased two S4 batteries + charger for $21 off Amazon.. I always carry a fully charged spare battery with me along with the charger. Only had to swap out once, that was when I was viewing movies..IMO, that is one of the S4 main selling points, a swappable battery!!

    BTW, this are not higher capacity ones, these are 2600Mah and same form factor as the OEM battery.

    With just texting and calling, meaning, mobile internet off, bluetooth off, pretty much everything off, i can get more than 24 hours of usage. That is with playing games and listening to music. Also power saving mode helps extremely.

    It seems like 2-4 hours of screen time over a 16 hour day seems to be in the normal range for me, depending on what I have turned on.
