• Samsung Galaxy S4: Battery Life

    By Chris Ward , March 28, 2013 - Leave a comment

    How many hours can you get out of the Samsung Galaxy S4 battery life?

    Updated Thursday May 2nd. Now that a few reviews of the S4 have surfaced, let’s have a look at what has been said of the handset’s battery life:

    Android Police

    AP list the battery life as one of the SGS4’s good points in their review:

    It’s good, though I did expect a bit more. The S4 by no means has poor battery life, but given its 2600mAh Li-ion cell, you’d think Samsung’s latest and greatest would keep on trucking well beyond a phone like the HTC One. It just doesn’t, though. The battery life seems ever-so-slightly above average, at least for a high-end phone. In fact, it doesn’t fare all that much better than the Galaxy S III. The Galaxy S III got pretty decent battery life, sure, but I think most people were expecting the substantially enlarged juice-box in the S4 to go a little further.


    TechRadar also speaks well of the S4’s battery life. Here’s an extract from what they had to say:

    For one person the Galaxy S4 is a treasured beast, only brought out into the dappled light to check emails manually once an hour for most of the day. For the next it’s an all-powerful media beast, one that will be streaming movies over a 4G connection while auto-updating every app under the sun.

    Whatever you use your phone for, in our eyes it should be able to handle what the handset’s main USPs are.

    But the good news is that the Samsung Galaxy S4 is able to handle all the things you can throw at it and still keep the 2600mAh battery chugging along at the end of the day. We found that in general use it was very well received, as nothing we found could hurt it.


    Pocket-Lint speaks more negatively of the S4 battery life than other sites, here’s what it had to say in its closing thoughts:

    On the negative side, we still think the battery life is a problem, and if you switch of the power-draining features, then you’ll end up with the same Android phone as everyone else has, so there’s not much point in that, is there? On the whole though, battery life and management seems better on this phone than the last. With normal use, we can get through the working day, so that’s pretty reasonable.


    AnandTech is possibly the most thorough site out there when it comes to testing battery life and goes into great detail. Here are the results of their tests so far (although they do mention that they’re not all that conclusive as it can only be applied to the Sprint version of the handset). It’s not that easy to summarise their findings in a sentence or two, but in their summing up they say:

    It’s difficult to say for sure given our Sprint review unit, but HTC likely gets the slight edge in battery life based on our results here today (although these two devices can be close competitors depending on the workload).

    Original Article

    Not many sites have gotten their hands on a review device yet, so it’s hard to comment definitively on Samsung Galaxy S4 battery life. However, GSM Arena has run some pretty thorough tests on its device and published a battery life review, so that’s as good a measure as any to go by for the time being. As soon as some more sites have released their opinions, we’ll update this post. Of course, we’ll be ranging some Samsung Galaxy S4 accessories  to help improve on battery life as well, such as the extra battery kit pictured below.

    The Samsung Galaxy S4 has one of the biggest batteries on the market, measuring in at 2600mAh – that’s almost a 25% increase on the size of the Galaxy S3 battery. However, it also has a whole lot of technology to power, including that massive 5″ display. It’s important to bear in mind that the different variants (there’s a quad-core and an octal-core version) of the S4 will offer differing performance when it comes to battery life, but GSM Arena had the quad-core (Snapdragon 600) version, which is the one that will be available in the UK.

    Note: we’ve included screen shots of the condensed version of the GSM Arena tests here. If you visit the post itself (link at the bottom of this post), you can see an expanded version that has a greater range of handsets.

    Samsung Galaxy S4 Talk Time

    The Samsung Galaxy S4 fairs up pretty well in this test, although it’s beaten by rivals such as the Nexus 4, Sony Xperia Z and Motorola RAZR i.  The Galaxy S4 talk time measured in at 13 hours 53 minutes and top of the list – as you’d expect – was the Motorola RAZR MAXX with 21 hours 18 minutes.

     Samsung Galaxy S4 Web Browsing

    The results for web browsing time place the Galaxy S4 6th in the list with 8 hours 42 minutes, which isn’t bad considering it’s competing against the likes of the Note 2 and RAZR MAXX. However, one of its closest rivals, the HTC One, comes out on the very top with 9 hours 58.

    Samsung Galaxy S4 Video Playback Time

    The Samsung Galaxy S4 also fairs up pretty well when it comes to battery life for video Playback. Sixth in position again, it will give you 10 hours 16 of video viewing – more than enough to watch a few films on long journeys.

    Overall these early indications show that we can expect a pretty good battery life from the Samsung Galaxy S4. It’s offering a good balance for carrying out certain tasks and it should event get power users to the end of the day with one charge. We’ll have a look at some more opinions and update this post once more reviews have gone live.

  • I wonder how the exynos 5 octa version will fare, though the UK won’t have that one if I’m not mistaken. Gsmarena tested the snapdragon powered version

  • Yes at the moment it’s only the quad-core version that is planned for UK release. Not sure what to expect of the octa-core variant in terms of battery life. Having an octa-core does seem like a little bit of overkill, but at least it helps to drive down the cost of quad-cores.

    • My understanding: It’s not really an octa core but rather a 1.2Ghz quad and a 1.6 Ghz quad. It will help battery life by quite a bit maybe 2 full days as the lower power quad will be used for functions like the internal clock and retreiving email. The more powerful will only turn on when video or audio is used which is the power hungry part of batteries. In comparrison the UK and US version will always use 1.9Ghz when it is turned on even to check email or the time.

      • Yes that’s correct Bruce. It will be interesting to see how the two S4 variants measure up to each other when put through the same tests.

  • The difference between the processors should be minimal, the quad core processor can still rev up and down depending on the amount of processes running so the difference between the octa core and quad core shouldn’t be much, if anything the quad core might be faster as it has more ghz

  • I’ve just returned my HTC One as the battery was dire. I’m my own tests, I could play videos for around 5 hours, which seems to be at odds with the results you quote here. The real deal breaker though was using it in the real world. I took it to the gym yesterday morning, used a fitness app for an hour and a half (not with the screen constantly on) and listening to music with my bluetooth headphones and it had gone down to 75% 2 hours later. And that was with wireless disabled. When I took it out on Saturday I left the flat at 12pm, watched maybe an hour and a half of video on the move and it was on 20% by 11.30pm. It was just woeful.

  • I’m using the AT&T version of the Galaxy S4 and I barely get 2 hours of web browsing.
    Not sure where the 8 hours figure came from.

    • Hi Gil,

      Is that over Wi-Fi or the mobile networks? 2 hours by Wi-Fi sounds very low. I think the above figures are referring to Wi-Fi rather than 3G/4G.

      • It is over wifi. Based on the battery application, it seems over 50% of the power is wasted on the screen. I wonder if the camera usage for eye tracking is considered part of the screen usage. Any experience with this?

  • Some of the S4 batteries out of the box needs conditioning simply discharge the battery until it switches off the phone. recharge only untill 100% this will improve its performance keep doing this over a few days and you will get back a good power storage

  • Samsung galaxy s4 when it is working it gets too hot?????????

    • Hi there, modern smartphones do to tend to heat up when performing processor intensive tasks such as streaming video over a data connection or gaming. This can be added to if the battery is being charged at the same time.
      I would recommend downloading a diagnostic application to check the processor temperature if possible and checking with others to see if your device is at the same limits.
      If you believe the device is getting too hot then it may be faulty and may need a repair / replacement – if you have purchased from us then contact us at the usual email address sales@clove.co.uk, otherwise refer to your retailer
