Battery life comparison: Samsung Galaxy S6 vs Apple iPhone 6 vs iPhone 6 Plus

Battery life comparison: Samsung Galaxy S6 vs Apple iPhone 6 vs iPhone 6 Plus
The Samsung Galaxy S6 battery has actually gotten smaller than it was on its predecessor: a 2,550mAh cell comes to replace the 2,800mAh battery pack on the Galaxy S5, but in exchange for that we get a slimmer and lighter device. 

What's even better, Samsung claims that it has managed to retain battery level on about the same level and even better thanks to a number of factors like the more efficient processor and improvements in Android 5.0 Lollipop.

But how does the battery life of the Galaxy S6 compare to that of its biggest rivals: the Apple iPhone 6 and iPhone 6 Plus. Luckily, both companies are giving us detailed and directly comparable official figures for Wi-Fi browsing, LTE browsing, Video playback, and Music playback longevity.

Samsung is, naturally, quick to point out that its S6 actually beats the iPhone 6 by a slow margin in almost all categories (the iPhone 6 lasts a bit longer for music playback, but all else is in favor of the S6). And when you compare it with the very long lasting iPhone 6 Plus, we're seeing that it falls a bit short, but the difference is really very negligible.

Take a look at the official battery life ratings and how they compare between the Galaxy S6, iPhone 6 and iPhone 6 Plus.

i'll believe it when i see it, cuz all i know is my Note 3 supposedly had a better battery than my current 6 Plus and that's a big fat lie, the 6 Plus has way better battery life with smaller capacity and less efficient LCD display...

I doubt know what you're doing with it, but I know my Note 4 certainly outlasts the 6+.

I had a Note 3 and 6 Plus. My 6 Plus had much better battery life. My Note 2 had better battery life than my Note 3. With heach use I clear a full day without issue on my 6 Plus. I can't speak for a Note 4. In the end we each use our phone differnt so results varies.

Have you owned both phones? I have, and my Note 4 wasn't better on battery than my 6 Plus. Every use case is different, but for my usage, the 6 Plus has been the best phone I have used for battery life.

Hold on a minute Apple Boy!!! You were ALLLLL over Note 4 articles when it was released bashing every aspect of it, but you ended up buying one??? There is something fishy about your story, even Harry Potter's movies are more believable than yours.

Let me ask you a question. Do you own a car? What type of car do you have. So let me ask you this, do you need to own a Porsche to know its a better car than the one you own now? Do you need to touch fire to know its hot? Do you need to get hit by a car to know it will hurt? I know the Note 4 is better than the iPhone 6+ and I have never owned an iPhone 6+. How? Well let me see, the Note 4 last 2 hours longer than the 6+. 1440p display is better than a 1080p one. The 16MP camera with OIS is better than the one on the iPhone because the iPhone only has a 8MP w/OIS. The front camera at 3.7 on the Note 4 is better than the 1.2MP camera which was on phones as of 2004. The Note 4 comes standard with 32GB of internal storage, while the iPhone 6+ starts at 16GB. The Note 4 is $699 of contarct, while the iPphone 6+ is $849 off contract. The Note 4 won't bend in my pocket, the iPhone 6+ will. Now, with that list and te fcat I can list over 50 things the iPhone 6+ can't do vs the Note 4; my question is - Do I need to own an iPhone 6+ to confirm which one is better? You are a trolling fool if your only argument is, you can't speak of a phone I don't own. Seeing that the iPhone 6 and 6+ aren't that much different from the iPhone 4/4S I did own, I'd say I'd personally have a very good idea as to why I know as a fact, the iPhone hasn't been as good as the Galaxy S, no matter how well it sells. Just like I know, McDonald's will sell over 1B hamburgers this year, but I know as a fact they don't make the best burger. PERIOD.

I own lots of phones, from all 4 major OSes. I've owned every Galaxy S and Note, by the way, along with the Nexus S and Galaxy Nexus. It's a rarity that I use the same phone for more than a month.

LOL. I'm using a BLU Studio Energy right now. I pulled it off the charger this morning at 9am, it's 6:46pm right now and it's still at 94%. Eat that! I left it sitting there one day to test it's standby endurance, I checked it 13 hours 22 minutes later and it had dropped 1%. Do that math, that's over a month of standby time.

Did you have a sim card in it...? I'm just wondering, cuz when I had a Galaxy Light sitting home with wifi on, many apps and game installed, and no sim card, I got just about 4 weeks out of it on standby. It doesn't have a big battery. (I actually had 2. One was my daily driver, and the other one just sat there for over a month.)

I'll believe it when i see it, and i am talking about you having a Note 3. I had the Note 3, and with everything turned on, i used to get easily 5 and half screen on time. With the Note 4, it is bumped up to 6 and half to seven hours of SOT.

iphone battery has better life expectancy by far!

26. engineer-1701d unregistered

it depends on the carrier your with lte band strength and network connection so if you have bad carrier cough cough sprint then higher battery use if your full bars then that means your still connected and downloading info for emails pinging location facebook updates and any other updates. you need no apps installed and no location turned on and same network thats close different antenna give stronger signal and reduce battery usage p.s. babyboy are u a guy or girl cant tell from that pic hint hint change it

I am a heavy user and both my Note 3 and Note 4 outlast an iPhone 6+ and quite a lot. Under medium usage the 6+ gets closer, but is still behind. From my experience iPhones only really perform well against Notes on standby time, when being used they fall well short.

I'm really confused.. everyone say that Samsung has better battery life example Note 4, but as owner of Note 4 i get only 5-6 Screen on time.. comparing my dad's Iphone 6, he gets 6.5-7 hour

dont forget the screensize and the resolution!! if the note 4 had that same resolution of the iphone 6plus the note 4 would be clearly and easy the winner

iphones dont say screen on time like android phones do. iphone usage =/= screen on time.

Sounds like you have some serious faulty (as in draining) apps installed. I can sqeeze more than 5 hours screen on (actually browsing) out of my ancient S2...

Running on what ROM, stock or custom, and if custom, the name and Android base version? Maybe I will dust off my SGS2 and put it to use.
