Murtazin: Samsung Galaxy S7 to feature up to two-day battery life

Murtazin: Samsung Galaxy S7 to feature up to two-day battery life
Russian tech blogger Eldar Murtazin disseminated a tweet last week, claiming that the Samsung Galaxy S7 battery would be able to play 17 consecutive hours of video at full brightness on a single charge. Without hearing that from Samsung, we certainly have to take Murtazin's tweet with a grain of salt.

Murtazin posted a follow-up tweet on the subject just the other day. This one contained a diagram implying that the Galaxy S7 will provide users with up to 48 hours of power on a single charge. The screen-on time measured about four and a half hours, and the brightness was set at 75%.

The Samsung Galaxy S7 is expected to carry a 3000mAh juicer inside, up from the 2550mAh battery powering the Samsung Galaxy S6. Speaking of the Galaxy S6, our custom battery test showed the handset running 7 hours and 14 minutes before demanding to be fed. To put that in perspective, the top phone on the list when the test was run last March, was able to ride its battery for 10 hours and 42 minutes. That model was the Motorola DROID Turbo, which carries a 3900mAh cell.

The Samsung Galaxy S7 and Samsung Galaxy S7 edge should be unveiled later this month, February 21st to be specific, during the Samsung Unpacked event. That is the day before MWC kicks off in Barcelona. Battery life should be improved with the Marshmallow feature Doze included. With Doze, inactive handsets are put into a deep sleep state, and apps are cut off from the network until they are needed.


Thanks for the tip!

I can get 2 days with over 5h SOT with Note 5. So this result is not very good

What am I missing? How is the SoT other 4.hours 1or so and yet I can watch a movie for 17 hours straight. When you watch a movie for 17 hours the screen is going to be on. Watching a movie is more incentive than anything you will do one your phone other than making call and playing a top end game. This is like saying, my car holds 20 Gallons of gas. That in get better mileage in the city stopping and going, than I would on on a wild open higheay. Think aboutbthis. You car burns the ssame amount of gas whether you are on the road or city driving g. As long as you aren't trying to do 50mph to the next stop light. But because of all the stop, you simply aren't covering as much groind. Watching a video is way more intensive seeing that your GPS is constantly rendering graphics while the CPU is handling other tasks. If your car is on, it's burning gas whether you move it or not. Sure it won't burn as much sitting still, but it will burn. Something isn't adding up.

It doesn't add up because your assumptions are both wrong. Your car does not use the same fuel city driving vs open road. I have no idea why you even mention this in relation to battery life on a phone. But whatever the reason you're wrong. Also watching a movie on your phone is absolutely not the most intensive thing you can do with it. It's right about the lowest which is why you can get high numbers for movie playback.

2 days battery life for a samsung flagship phone. This feature has been long overdue for expensive handsets, good thing samsung is now listening to the consumers.

I think the S7 is definitely going to have better battery life than the S6 but let's not overhyped and disappoint ourselves with reasonably unrealistic claims that are still subjective to usage. I pump my phone on 100% brightness and usually am on LTE, so I get around 4 hours of on-screen time

Once again not a true life test I bet. I bet everything apart from the screen was off, wifi, date, & I bet the phone had no apps like Facebook that drain the battery. I guess the relevant world battery life will be more like 15 hours, if we are lucky.

In the real world, you get different battery life on different days depending on what you're doing. Reviewers don't even use their phones the same from site to site, which is why you get some reviewers claiming much longer battery life than others, or vice versa.

I can go maybe a day and a half with the Nexus 6P. It's nice to read that companies are working on battery life for their flagships. Lets just hope there's truth in this guy's tweets.

If true, this is great, since I use my phone to watch video a LOT.

Once FACEBOOK and other battery guzzling Apps are installed, you know what's going to happen

GS7 vs. the next high Xperia for me! Premium phone with at 10 hour SoT on acceptable brightness and moderate usage would be awesome. My brother's GS6's standby performance is terrible so hopefully Samsung has picked themselves up there too.

Yawn....I don't play 3d games, or games at all on my device, but 1500-2000 minutes/month on the phone, tons of photos, web, email, text, mp3's and my phone gets 2-3 days EASY. Of course it has a 4,050mAH battery, which helps. :)

I highly doubt it will be able to marathon the way my Galaxy S6 Active does, on a bad day I get a day and a half.

Who keeps their phone at 75% brightness, that would blind me. I keep my GS6 at about 30% and that is more than enough for me. I am really happy they have focused on battery life.

yeah, same. the s6 screen is really bright and i rarely go beyond even 40% at any given time, so if i was the one using the s7 at around 40-50% brightness, i might even crack 7-8 hrs of SOT

5. Unordinary unregistered

Lmfao totally possible if you define "regular" use as not installing any third party apps, non fetch e-mail, SMS, UPSM 24/7 and make a one or two phone calls. Oh, did I say no 3rd party apps like IG, Snapchat, FB, etc? Lmao. I'll believe it when I see it

Way to go Samsung! I just hope they fix touchwiz lag. Then I will for sure get one.

35. TerryTerius unregistered

They did, last year. The only issue I ever encountered on the S6 for the time I had it was the rare keyboard slowness (pulling it up). Not that it really matters because any phone you ever get is going to occasionally stutter and have problems. I've never used an electronic device in my entire life that was completely without issue. Then again, I guess that depends on how you define lag. I don't consider something taking a millisecond longer to be an issue. That being said, I do hope they fix their ram management problems.

If that's true, then big Kuddos to Samsung. That's bound to be a feauture that will attract many users!

Still only 4 hours and 32 minutes of screen on time during that 2 day period...not really ground-breaking considering what I've experienced: https://db.tt/IOMyQBaN

You realise that WiFi and 4G are extremely different scenarios. And 75% brightness too. Based on my personal experience and this screenshot, with Wifi, 30% brightness(my preference), this phone should easily break 6, if not 7 hour SoT. Regarding achieving high battery life, this is what I was able to achieve with S6 on 5.0.2( it has decreased tremendously with 5.1.1): http://3.bp.blogspot.com/-1y8L9ga95WM/VU9S8-0eLPI/AAAAAAAADgQ/gjASWW5UzRw/s640/Screenshot_2015-04-15-22-08-41.png

That's very impressive SOT on Lollipop! Would probably be even longer when Marshmallow lands for the S6 with Doze. Here's hoping the S7 only improves on that.

18. TyrionLannister unregistered

That glory was short lived. Once 5.1.1 dropped, battery life tanked. Now it's hard to get past 5 hours SoT.

What were you doing on your phone? The highest usage app was internet and that was only 3%. This doesn't make sense.

28. TyrionLannister unregistered

The percentage tracker on samsung lollipop is screwed up. I mostly surfed the Web, watched a movie and viewed a lot of YouTube. It doesn't show the true percentage and the addition of all the usages add up to like 40-45% whereas they should be 100%. It's fixed in marshmallow but just ignore those percentages for now. They are obviously crap. I give a perspective, I'm currently on 20%. So the usage stats after adding should add up to 80%. But they only show 19% usage. It's so bad it's unusable. If you want true battery stats, uI'll have to use GSMA monitor.

That's really impressive. How is it that you only have 3 items using the battery ?? When i check on my s6 there are always 8 to 10 apps or process eating my battery. If you have a few tips...?

55. TyrionLannister unregistered

No. There were a lot more if you scroll down. Just disable wifi always on from wifi menu and disable samsung junk like samsung push and s health.

7. Nopers unregistered

That must be wrong. My iPhone 6s Plus can get about 9 hours screen on 36 screen off. I'm hoping it was intense usage like heavy gaming, I was really looking forward to getting an S7

10. TyrionLannister unregistered

You can't get screen-on time on iOS. That 'usage' thingy in battery section is just the time the phone was working. That includes sync and pulling notifications or playing music when screen is off too. My iPad gets like 20-22 hours of 'usage' in battery section on a single charge. The real SoT is closer to 12-13 hours.
