Our Samsung Galaxy S6 edge battery life test shows flagship-worthy endurance

When you have a 5.1-inch display that curves to the sides whilst holding as many as 1440 x 2560 pixels (a massive 576 ppi), and only a 2,600 mAh cell to keep things moving along, you're allowed to be skeptical. And skeptical we were about the Galaxy S6 edge, at least in terms of battery life – seemingly the only variable in the lengthy equation that is Samsung's latest flagship. Fortunately for you and us both, the electronics giant knows what it's doing...

Haha. here we go again. Even with a smaller batter than both the iPhone 6 and 6 Plus, it still managed to last longer than both of them. And like the Note 4, it still has double the hardware. quadcore vs dual, 3GB of RAm vs 1GB, 32GB internal vs 16GB, 5/16MP camera vs 1..2/8MP, full multi-tasking dual quadcores, 1440p vs 750/1080p, and so much more. Anyone who yet again still thinks the iPhone is premium needs to see a psyche. This an you can charge the phone to 50% in 30 mins and get 4 hours of usage from a 10Min charge, and wireless charging and a pay system that support 90% of existing retail infrastructure. The Galaxy S is and has been the rtue contender vs the iPhone and has made every mode l of th eiPhone look dated. It si sad that the iPhone 6 models can't even beat the year old S5, so you know it stands no chance vs the S6 models. Apple will still have high sales, but the S6 models and when the Note 5 comes, Samsung is goign to sell 350M+ phones making it 3.5 years in a row they sold 80M phone per quarter. Yet all the PA Ifans boys were so happy about Apple selling 75M phones one frikkin time. You guys much sniff a lot of glue. Until someone makes a phone that matches what Samsung is offering, I won't be switching.

Except that iPhone 6 has 1800mAh battery and S6 has 2600mAh battery.

iPhone 6+ is using 2,916 mAH battery and it's still worse than the S6. Bad coding by Apple.

it was absolutely stupid of samsung to go down the ultra thin smartphone route a smaller battery will always be bad for consumers & shows once again that manufacturer are more interested in PR "look how thin out phone is" then use the excuse it charges quick & wireless charging. What I want is a 2 day battery or something as close as we can

To make all your arguments to rest about the battery life of s6 edge i did the simplest of math calculation, let me expound: 1. Standard screen luminance is supposedly set to 200 nits, however, the edge can only reach to 180 nits max according to PA. Therefore there's a 10% difference to all other test subjects. 2. Extrapolationg the anecdotal 8h11m endurance of the edge and subtracting the 10%, which is roughly 49m, difference equates to an adjusted endurance of 7h25m. 3. Thus, if we take into account regular s6 endurance of 7h14m and compare it to the now adjusted s6 edge endurance of 7h25m, we can clearly see that both devices have an almost exact endurance. Giving a slight, albeit, negligible advantage of s6 edge roughly in part due to a 50mah boost battery specs compared to regular s6. 4. This gives credence to PA's methods in calculating endurance ratings because of the consistency it produces when other people try to analyze the numbers posted in public and coming out of their own analogy and recalculations. 5. Im a fan both of gsma and PA, they just do different battery life statistics. However, either websites do their best in testing new phones so that us consumers, are well-informed before we make the purchase with our hard-earned money. Because frankly, regular joes like us don't have the resources to buy every single flagship on release and later on finding out that it didn't meet our expectations. That is why PA and GSMA are here to help us all out. So enough with your bashing trolls, be appreciative of all these guys and gals efforts to keep us consumers well informed. Thanks PA! :)

Why don't they try and improve battery life rather than trying to match the predecessors?

Because they weren't trying to match. And considering the S6 offers more than the S5 and it has a smaller battery and t nearly matched the S5, I'd say that's a good thing.

I have the LG G2 and dropped it in the graph. It is slightly less on this test than the S6. I've been impressed with my G2s battery life so the move to the S6 from a battery life perspective would be a non-issue (again based on this test).

What is amazing here with just the S6 has a smaller battery vs the iPhone 6 Plus. It has a smaller screen sure, but is 1440p vs 1080. Has dual quadcore CPU's vs just a dualcore, has faster RAM @ DDR4 vs DDR3, has better cameras, full multi-tasking and so much more. Yet, it managed to last nearly an hour longer than the iPhone 6 Plus. Plus it charges in half the time from 0 to 100%. All of that and the S6 starts at $680 for 32GB while the iPhone starts at $749 for 16GB. The previous S models were $650 off contract and so was the previous iPhone. The S6 is a much better upgrade above the S5 considering the iPhone 6 isnt an upgrade over the 5S. All it got was a new look and the same internals. Sammy is simply the true innovator here. Not just in designs, but the fact you are getting a real "premium" device at a reasonable price point, while Apple use the bottom of the barrel materials and raise the cost and the fools still went running to buy.

Something is wrong in this test. Make them again PA, S6 Edge is too much over the S6 "normal". 20 nits can't do this large effect on battery life. I think Galaxy S6 7,x hours battery life is more "realistic" for a 2600mAh battery... I don't believe in miracles! ;)

We need actual Screen on Times posted from the specific phone models on LTE or 4G Networks. Graphs and charts and simulations tell us very little about real world usage. Using Wifi Only Tests defeats the purpose of the Test. Mobile Phone on a Mobile Network Screen On Times during 10 to 12 hour day at a usable indoor brightness ( specified) would be what we need to see.
