Galaxy S6 Active battery life test shows how far can 3500 mAh go

Galaxy S6 Active battery life test shows how far can 3500 mAh go
Our review bee is working hard on outing their first impressions from the Galaxy S6 Active, and we know what you are most curious about - this phone has a much larger battery than the Galaxy S6 itself, after all, right? With a 3500 mAh unit, how do Samsung's frugal screen, chipset, and software optimizations fare, when compared to the 2550 mAh unit in the S6?

Well, our proprietary battery life benchmark has been done on the phone, and it shows exactly how good has Samsung gotten at optimizing its flagships for a great ratio of battery capacity and longevity. We got a bit over 12 hours of screen-on time in our demanding test, which jibes with Samsung's stated 16 hours of video playback on a charge, and the phone's 40% larger battery capacity. On the minus side, it takes 103 minutes to charge the battery to its full potential, compared to 78 minutes for the Galaxy S6, yet this is still an incredibly fast charging time. 

Last but not least, Samsung managed to achieve this excellent battery life result, and ace the drop and waterproofing tests in the process, while keeping the thickness of the tough handset at the reasonable 8.6 mm only - a far cry from the usual chubby ruggedized handsets we are used to seeing. The Galaxy Note 5 is rumored to have a sizeable battery as well, so we can only imagine what its battery life will be, if the rumors hold water.

Battery life (hours) Higher is better
Samsung Galaxy S6 Active 12h 9 min (Excellent)
Samsung Galaxy S6 edge 8h 11 min (Excellent)
Samsung Galaxy S6 7h 14 min (Good)
Sony Xperia Z3 9h 29 min (Excellent)
LG G4 6h 6 min (Average)
HTC One M9 6h 25 min (Average)
Huawei P8 7h 12 min (Good)
Charging time (minutes) Lower is better
Samsung Galaxy S6 Active 103
Samsung Galaxy S6 edge 83
Samsung Galaxy S6 78
Sony Xperia Z3 235
LG G4 127
HTC One M9 106
Huawei P8 180

I don't think so. World wide it's not gonna happen. Those previous phones like S4 Active, S5 Active, S6 Active only selected country. Maybe 100,000 units they make only.

High battery capacity is acheiveable in thin form factors. Right now Chinese manufactuers are outting phones with 4000+ mah in 9mm thin phones. If they can do it, im sure the high end manufacturers can do it. I just bought a phone from China called the Bluboo X550, it has a 5300 mah battery, 5.5" screen and its a little thickner than the LG G3/G4. Thats a great acheivement, and another Doogee phone mentioned on Phonearena is coming out with a 6000 mah battery in 9mm thin package. Being on T-mobile it'll be easier to order these phone which are quite capabale for under $200.

Why hate thats how the basic S6 should been. i am selling lots of S5 active at my store ( its same price as the S5 and much better all around and better build quality ) Still it is not trully a rugged device its more like halfway. a good device for someone who do a lots of outdoors activity and take good care of is phone ( will still break if droped from too high ) Real rugged device come with a warranty against it been broken and not many OEM do this. Want to call your device rugged give the warranty thats come with it free of charge. But for the battery size they done the right thing. I am just been logical here :) And yeah i hate the crappy build quality of most Samsung handset ( excepted the active and note serie ) as they have the highest return rate ( in % of return per phone sold ) vs all other oem even iphone is a bit lower...

Why is there an hour difference in the Galaxy S6 and Galaxy S6 Edge? That alone calls into question how meaningful these results are. Impressive though from all the Samsung phones considering battery size.

S6 Edge has a bigger battery than the standard S6. Edge tends to get about 20% life left inside by the time the standard S6 dies.

Yeah right bcoz that bigger battery of 50mah is making all the difference. -.-

*Because Okay, well I'm guessing you haven't done the test yourself yet, so you can go try it yourself, or go watch/read the comparisons which notice extremely similar results.

It just means that PA test is not reliable or both phones were not at same firmware.

They couldn't set the screen of the edge to the same brightness as the s6's, so it was a bit dimmer, which in combination with extra 50 mAh gave it an unfair advantage over the base s6. All in all, I'd treat edge's battery life result with a pinch of salt.

13. Shocky unregistered

50mah? Yes, because that equals a whole hour. Don't be daft.

I don't know why you're all crying about this fact :P Go try it yourself

I have tried them both actually, there is no noticeable difference in battery life between the two phones, both will give you around 4 hours of SOT. FYI I had Galaxy S6 and now I have a Galaxy S6 Edge in emerald green because it looks stunning. :D

From what I've read the s6 has better battery life (real world) probably because of the edge(screen) feature it's self

Two reasons and I'll start with the less influential one: 50 mah less battery capacity. But more importantly, they test each phone at 50% brightness where the S6 is calibrated at 200 nits and the S6 Edge at 180 nits. And before anyone jumps in and cries "faul" , most other phones are below both at 50%. For example the G4 almost half that....

Incredible. If only the original S6/edge was as good.

And S6Edge Plus on the way too w/ a bigger battery. another recordbreaking?

15. TyrionLannister unregistered

It just means that S6 should get another test. The numbers don't add up. The active only has 37% bigger battery and manages 68% higher result, with the same hardware. The software updates must have done their job.

that just means PA's testing most likely mixture of operations favors some that are less battery intensive as others

Are these Samsung phones "optimised" for tests like this as they were for the performance tests in the past? I ask because a friend has had an S6 edge for a couple of weeks and while it's a nice phone, the battery life pretty much sucks, even with all the online tips for longer life followed... Her previous S3 was better.
