Galaxy S5 scores amazing on our battery life test: the longest-lasting flagship has the endurance of a tablet

Galaxy S5 scores amazing on our battery life test: the longest-lasting flagship has the endurance of a tablet

Are you sitting down? You'd better be, as we have a new king of our battery life test, and it is none other than Samsung's Galaxy S5. It managed the whopping 7 hours and 38 minutes of screen-on time in our grueling battery endurance run, which is the best result we've seen so far from any flagship. It actually stopped just a few minutes shy of the Xperia C, or it would have been the phone with the longest battery life we've ever tested. For comparison, it closes in on the most enduring device we've measured - the Galaxy NotePROiPad Air, and iPad mini 2, but those are tablets, with the respective gigantic battery capacities.

During the phone's unveiling event, Samsung promised up to 10 hours of Internet browsing, 12 hours of HD movie watching, or 21 hours of 3G talk time on a charge, and we can attest that the Galaxy S5 meets and exceeds those promises. Manufacturers, as well as most third party services, measure battery life with the screens set at about 150 nits of brightness, while our routine script is run at 200 nits, and features mixed browsing and media display patterns. Those include a lot of white background, too, which AMOLED screens draw the most power to display, and still the S5 managed to break the flagship record. How has Samsung done this, though?

The notable thing with the Galaxy S5 is that it breaks the flagship record with "only" a 2800 mAh battery, surpassing even phablets with their huge 3000+ mAh juicers. Thus, there must be more at play than capacity alone here, and Samsung might have utilized additional battery-saving techniques for the first time in the S5.

Remember LucidLogix's battery-saving optimizations that we wrote about not long ago? At the time we mentioned that Samsung has inked a deal for implementing the PowerXtend battery-saving algorithms in a yet-unknown device. Well, that mystery handset turns out to be none other than the Galaxy S5 flagship. The PowerXtend suite comprises of three proprietary algorithms, called WebXtend, NavXtend, and GameXtend. All of them rely on better hardware management and load-balancing that are supposed to extend the battery life on Android devices. GameXtend is the most interesting here, as it allows up to 50% better battery longevity, while NavXtend and WebXtend promise up to 25% savings. Despite that these are software algorithms, they have to be implemented at a system level by the manufacturer itself, which is precisely what Samsung has done with the S5. In that case, Lucid's PowerXtend implementation might be the culprit behind the jaw-dropping battery life stats that Samsung promises for the Galaxy S5, and which we can now confirm to be entirely true, as you can see in the graph below. We only hope that other Android phone makers will adopt the tech, too, as battery life is the thing users want to see improved in their smartphones the most.

BENCHMARK

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

Excellent endurance, great optimization of that 2800 mAh battery Samsung!

S5 has one of the best screens and cameras, and now has the best battery life. Enough said.

Yes! That's what. Even the m8 provides great battery life. We can clearly see that just a bulky battery wont mean everything *cough*z1*cough*. Software optimisations and other factors like chipset, display and hardware optimisations matter alot also. S5 provides the best combo without giving up on specs at all. Just want to see how the z 2 manages, but knowing sony...meh.

Phone arena didn't test it in real life. They just ran Java script to get the result. How can people believe this fake result? even gsmarena battery test showed score is below the note 3... Stop this, it's not accurate! !!!!!!!!

no its not the best chip,,, the TEGRA4 and Exyonos 5420 is much powerfull and has more torque than the S801

the best chip is used by apple iphone5s which uses an ARM A57 A15 CORTEX, not this over clocked A9 CORTEX

Eeryone hates it cause its build with cheap recycled plastic and not aluminium or metal

look at oppo7 the best the grand marques of prestige phone, not this cheap plastic

If the Sony Z2 Tab has a life of 6h and 54min then that means the Sony Z2 smartphone will likely have a lower battery life then that...

I picked up my S5 today and it's AWESOME. People who still thinks the phone has poor design and quality build; go see the phone yourself ! The grey line that goes around the phone makes it look premium unlike the official render. It feels really good in your hand, and the "band aid" back is not true. It rather feels like they used the premium material from luxury cars for the back !

The phone has amazing display, battery, FEATURES, camera, and useful gimmicks! I highly recommend the phone!!!

LG G2 has better BATTERY IN TALK TIME AND BROWSING than S5!

see GsmArena.

Get over it. This is a valid test. I've achieved similar results to their battery test on my nexus 5. No two sites are going to give the exact same results as they all use different methodologies for testing. The SGS5 has excellent battery life no matter which website you go to, to make yourself happy. To whoever is posting HTC is the new king, did you even bother reading the article on anandtech? Htc lasted longer under some conditions and sgs5 in others. No phone is capable of longer battery than sgs5 when power saving is activated, even though device is somewhat limited with that feature enabled.

its still PLASTIC cheap low plastic, there is no sign of premuim touch to it when you hold it or touch the phone

m8 is pure class of its own with sumptous eptimome

well cause the wp platform has a light platform and dosent need heavy resources like android, but true that phone got 100 hours rated by GSMARENA

Why don't you tell us the overall battery life of G2 and S5 as well from gsmarena ? Let me tell you in case you missed it

LG G2: 62 hours (with 3200mah)
GS5: 72 hours (with 2800mah)

Also, these overall battery life is what general users care as no one talks or browses for 7-8 hours straight.

yet, no one would buy it, as I read in an article here 2 weeks ago that sales are weak. wow, why?

Yeah odd how the G2 smokes the S5 across the board in tests but was rated lesser.
First post on that thread at gsmarena, the poster calls out them stats as bogus too.

Everyone hates it? yet everyone buys it. what's an oppo...? is this a washing machine? a tv? what's that?

Dude, its simple logic. G2 has poor stand-by time in comparison to gs5. Hence, the difference.

Gsmarena and Anandtech are probably the most reliable names in this game.
