Samsung Galaxy S6's battery life test score trails that of its predecessor
posted by Chris P. / Mar 26, 2015, 10:48 AM
At 0.27 inches (6.8 mm), the Galaxy S6 is one of the thinnest mass-produced devices on the planet. But such remarkably slim profiles often require sacrifices on the hardware level, as there simply isn't enough space to fit everything. One component that requires quite a bit of room? The battery.
The Galaxy S6 sports a 2,550 mAh cell – a built-in one at that – and with that capacity it needs to keep a power-hungry, 1440 x 2560 Quad HD Super AMOLED display going for as long as possible. According to our custom battery life test that mimics the typical person's day-to-day usage, the S6's juicer manages 7 hours and 14 minutes before giving up, and then needs 78 minutes to charge from zero back to full – a good result, but not excellent.
Indeed, the Galaxy S6's predecessor, the Galaxy S5 (2,800 mAh), went through our stressing battery life test a year ago and scored slightly higher, at 7 hours and 38 minutes. Of course, it's quite obvious that Samsung has carried out a great deal of optimizations in terms of power efficiency, as the S6 is not far behind, despite its smaller battery and much more pixel-dense screen. Regardless, those among us that were more than content enough with a 1080 x 1920 resolution are probably a bit disappointed right now.
In any case, the Galaxy S6 proved to be a good enough performer, and is still ahead of the likes of the HTC One M9, the LG G3, and both the iPhone 6 and iPhone 6 Plus.

TWO HOUR MORE than the iphone 6 and you're complaining about it. Seriously?

8 hours of what exactly? "According to our custom battery life test" No detailed reference on methodology of measurement and firmware version. One could easily call it fake http://goo.gl/qIT2Mx

I'm sure if you emailed them, they'd gladly let you know the fine details. Different battery tests can easily yield different results. Same goes for EPA ratings with fuel economy, your mileage will vary depending on usage habits. Either way, it's a way to gauge the battery life, but not to be taken as gospel. I'm glad I got the Note 4 instead of the Turbo. Excellent battery life and awesome all-around.

It may be a proprietary script, in which case all details don't need to be told for a variety of reasons. What they do tell you, under their benchmark methodology link on this site, is that for this and all battery tests, the screens for all devices are adjusted to a brightness of 200 nits.

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! :)

Look it's simple. The small pretty phone with the bad battery and SD card situation is targeted at women demographics. The big Note phablet will continue to be targeted at men demographics. If you're a power user who wants the s6 to be a real power phone, you're SOL.

Future phones will never have replaceable batteries. Tablets dont have that option since i dont know... since they came out, duh!!! Technology will only get smarter and phones will get thinner. And for you to say that the s6 is targeted at women demographics,( lol.... sorry i cant.... lmfao,) is wrong! lol........

Completely wrong. Both men and women carry phones of all sizes. But he Note phones are catered to business people and not specifically to men. It just happens that more males are considered "business" people.

I'm still wondering why the S6 Edge has a noticeably better battery life than the regular S6. There isn't much different about them.

Not everything is iPhone related. Battery life generally gets better from year to year especially when you half the size of the processor in the space of a year. There's a lot of people who would rather have a phone that's a little thicker with bigger battery. That being said, I'll be getting the Edge

according to who? My Z3 Compact came with a 1.5Amp charger and it takes a lot less than what PA states They probably used 850mA charger which is the cheap one Sony delivers, the one they send to reviewers and midrange devices

Also, PhoneArena should do a test charging the phones using a generic unique charger... so this way it is completely fair, and you can actually measure charging times, instead of using the one from the box. My Z3C supports quickcharge 2.0, and PA never even tried that

no you should use the one that came with the phone you buy one of those cheap Chinese charge all you doing is damaging the charging port... at least with samsung I get a 50 percent discount who I use to buy at least 3 charger which came to be 17 dollar each

S6 Edge has only 50mAh more than S6 and there's almost 1 hour difference between them? You obviously did something wrong.
