How long will the battery last in this thing??Support

    I just want to know whether the battery will last more than a few hours after playing a game, recording 1080p videos, using the GPS, playing back music, and leaving apps running on it.

    All this emphasis on extra power is getting me worried. Obviously, the majority of us will be using the phone OTG and not be carrying a charger everywhere.

    So, with the battery's limited number of recharges (500 if it's left to completely depleat before being recharged) will we be seeing a lot of dead batteries after 8 months or so??

    It's great that Samsung were keen on making a super slim phone and all, but i'd much rather have seen a larger battery (3200mah) and have the phone be a few mm thicker. Do I have cause to be worried? My mate had to get an extended battery for his i9000 cos his original one died after 5 months.

    Battery technology hasn't improved from the last generation of phones, and an extra 150mah is hardly worth boasting about...


  2. Wow that's a huge battery

    Samsung says SuperAMOLED+ is 20% more power efficient over SuperAMOLED which was again 20% more power efficient than AMOLED. Dual core Exynos will be less power hungry than single core Hummingbird as well. So I don't think SGS2 will take any major hit in battery life over Galaxy S if not better.
    When it comes to battery life, I trust Samsung more than HTC. HTC has horrible record with batteries in Evo, Incredible, and Thunderbolt.

    Yeah, but how was that % calculated?

    was is efficiency = 20% less battery use, or

    efficiency = 50% better picture, but only uses 30% more battery which means it is 20% more efficient?

    I hate how these percentages are thrown around by these companies, but rarely mean what they imply.

    just saying...
  5. Should be good for at least half a day, industry standard. Samsung is the anorexic king and they aren't losin' to no one! No matter what the cost. The other big boys with thicker devices aren't doing any better, and the Atrix especially hasn't lived up to its 1900+mah battery. It won't be worse off than the competition, and that's all that Samsung really cares about, as well as the ultra slimness to appeal to the mass market. Battery specs don't sell, at least not in the demos that matter most.

    the mass market is changing tho. People want more than just style. No doubt that samsung will want to win the battery life war on their flagship device, and cpu scaling will play a major role in achieving this. Can't wait to see if there will be a compromise on performance to meet their typical battery life predictions. Make me a proud owner samsung!!

    The recent russian review on a prototype model said it lasted 5 hours on continuous video playback, screen on maximal brightness, WiFi and all Google sync services running in the background. I think thats fairly impressive to be honest, should last a day with representative use, which is all I need.
  8. I'd be lying if I said I didn't care about the thickness. I too complain about why they never put bigger batteries in smartphones but when it comes to these large slates, a couple mm does make a big difference, in looks and feel. Smaller footprint devices like sliders and flips under 50mm width can get away with thicker bodies and still seem okay even with a bulge in the pocket, but a thick slate is more unwieldy. I'd be okay with 11-12mm body and the rest for a bigger battery and camera and speakers, but I'll just sound like a broken record. Slimness trumps all, for better or worse.

    im keen to feel the temp as well.
    Its easy to say a slimmer phone would be closer to the running hot bits, but a few mill's should make that much difference.
    the dual core "should" run cooler anyway though.....i hope.....
    i saw a clip when a guy claimed it was quite warm in his hand but he couldnt tell how much it was used before him.

    I read a preview that mentioned it gets quite hot, hotter than the SGS1, and that the back is plastic rather than metal to stop it being too hot to hold comfortably. I suspect it is to keep the weight down more than that, but evidently it will get hot if cores are running flat out for long.

    But that won't happen on every day use.
    The thing of testing and reviewing is stressing the phone like you wouldn't do
    every day. So I don't think the phone will get all that hot when you just
    use it...

    Hmmm. I think you'd want metal to help dissipate that heat. I've actually had instances where my Incredible powered off due to overheating.

    The problem is that the heat is dissipated into the owner's fingers. After 3 hours of Angry Birds, that might not be a good thing. That's not every day use (if it is, you need help) but if you watch movies it might get uncomfortable. Then again, this was off one random preview so I don't think there's much to it.

    There is no battery cover on the back of the SGSII correct? (Sealed unit)

    Also, I wonder how long a Nokia 5110 would last on today's batteries? :p

    It's not sealed, the cover is the textured bit you can see in photos.
  16. I remember the galaxy s getting warm during phone calls. Would make my face sweat a little with the heat from the screen while talking. The back was kind of warm too. The battery is the toastiest thing in a phone and superthin designs have their drawbacks.
