Galaxy Note 7 battery life testing reveals handset does better than predecessors

Galaxy Note 7 battery life testing reveals handset does better than predecessors
The Galaxy Note 7 proved a tricky phone to run battery life tests on. Long story short, we had to run our custom battery benchmark numerous times until we got reliable results we could show you.

But! The data is now more than conclusive, and it's telling. What is it telling, exactly? Well, there's one key takeaway we can spot right away: the Galaxy Note 7 has the best result in the whole Note family, including daddy Note 5 and granddaddy Note 4. Kids these days!

In fact, if you look at the battery benchmark chart below, you can see that there's been quite a steady progress with each new generation of Samsung's monolithic smartphone. Compared to the venerable Note 4, battery life improvement in the Note 7 comes out to the tune of 12%. From the Note 5, it has increased by around 7%, at least as far as our state-of-the-art battery benchmark system is concerned, that is.

Now, we'd like to put up a big disclaimer sign right here, and it's going to read the following: "These are Exynos variants we're talking about!" As the more tech-inclined among you probably know, the Snapdragon variants Samsung usually sells in the US tend to last a bit less on our test. The same is true here – we tested the Note 7 with Snapdragon 820 as well, and it lasted 7 hours 55 minutes. Whether or not such a difference in performance will also be observed in real life is unclear. But hey, if this is the sort of thing that could ruin your mood for the day, maybe you should think about sorting your priorities out!

Anyway, we've also thrown the iPhone 6s Plus into the mix, which is what we'd consider the Note 7's biggest rival for the next, like, three weeks. The 6s Plus' result is the same as that of the Note 5, so the difference between it and the Note 7 is again 7%.

So now you know, the Galaxy Note 7 doesn't compromise on battery longevity; it actually improves upon the already strong showing by Samsung phones in this category. If you'd like to see the Note 7's battery test result compared against those of other phones, simply use the "Add phone" option at the bottom of the chart.

I saw from other report, Galaxy S7 Edge performs much better than Note 7.

That's likely true in which battery life concerns, but S7 Edge it's not meant to be the Note 7 predecessor.

But if you add S7 edge in this list, it is behind Note 7, even Note 5 has better results, but everyone knows it isn't true.

S7/S7edge battery test in this site is kinda broken

I get about 10 hours with my note five with medium use. Yes I have tested it from the time the battery is full tell it gets down to about 15%.

I was able to easily get 2 whole days of use out of my Note 5, same with my 6S Plus. S7 Edge lasts the whole day for me but that's it. Because this battery test (and the one they're going to use in the comparison charts) is the Exynos variant, so all users in the US likely won't even see this on their Snapdragon models. Note 5 in the US is still the best that we'll see in terms of battery life with the Note series, until a year from now when we will maybe sorta see better battery life in a Note.

And it's true. S7 edge has better results than Note 7 in battery.

And it is about S7 edge with SD820. S7 edge with 8890 is better.

Battery life is excellent, so far. But, as with all sealed battery phones, it will degrade with time and charges. That's why a removable battery is superior.

5. sarcastic_nerd unregistered

Batteries degrade to about 85% performance in 500 cycles in worst case. That's about 2 years. People make a big deal out of battery aging over time. You will have more battery life degradation from the apps you fill the phone over time with and the general hardware being outdated for future apps. TL;DR: it's blown out of proportion.

It's not. I saw more than 15% degradation in my Note 5 in just a year. That's probably because of fast charging, which damages the battery more quickly. I've got it turned of on my Note 7. This isn't even taking into account the convenience of being able to go from empty to full in less than a minute. Removable is in nearly every way a superior setup.

I'm not sure if it's because i don't have facebook running on my phone (moved to tablet) but my battery life is very similar to the day i got it. Nothing more and nothing less. I've been using external battery even with note 3 so it wasn't much of a hassle at all

16. sarcastic_nerd unregistered

As I said in my comment, battery life degradation is VERY VERY DIFFERENT than battery degradation. Battery life degradation can occur due to software, the amount of apps and cache you have, and other factors. I noticed a battery life drop on my S6 edge after a year too. Just to sate my curiosity, I swapped the battery for a new one(Samsung charges 40$) and noticed almost no gain in battery life whatsoever from the new battery. Now, I did a factory reset and then saw tremendous gain in battery life and back to the level it was in 2015 when I got it. Removable is not a superior setup. It makes the phone harder to make and compromises the build quality of the phone. You can get the battery replaced after a year if you want so from Samsung itself for pretty cheap, if you are feeling like it.

I turned off fast charing on my S7 edge since the bastery lasted more than long enough for the whole day and I charged it overnight with AOD turned on Battery life is still good.I'll do the same on my Note7

False. Qualcomm has stated that quickcharging a battery that was "DESIGNED" to be quickcharge does not degrade the battery any faster. I don't know why you guys continue to make that claim when it is false. A fast charge capable battery degrades at the same pace as a battery that is not being fast charged. "Q4: Can Quick Charge hurt my smartphone's battery? A: Quick Charge operates within the design parameters of batteries found in most smartphones. It is just charging the battery the way it is designed to be charged. Device manufacturers build smartphones with a specific battery that can accept a specific level of charge. The battery size and maximum current of each battery are design decisions made by the manufacturer and can vary from smartphone to smartphone, tablet to tablet and so on. However, traditional battery charging technology does not come close to the full power requirements of today's large batteries. Quick Charge is designed to allow device manufacturers to achieve the full rated capability of the batteries they choose while still meeting the performance and safety standards set by the battery manufacturer." As long as the battery is designed to be quick-charged, it will last as long as a battery that isn't being charged quickly. Its just charging at a higher voltage. Voltage is not what kills a a battery A batteries life is controlled by how many times it is charged and discharged, not how fast or slow its charged.

Techie is right fast charge dont damage the battery unless you do it when the phone is very hot. so i recommend to wait 15 min before charging after gaming. Still cant be faster than swaping battery. Also external battery on a phone have the advantage to spread out the recharging to many battery. If i do 1000 charge in a year ( exagerating ) If they are done on a single battery its will kill it faster than on 3 different one.

IMO if you just plug it in and quick charge, it wont cause any extra degradation But if you use it while its quick charging, and if that leads to your phone heating up, then it can cause extra degradation Unless you have an Oppo or OP3 which uses a different method of quick charging which doesn't cause any extra heat

Qualcomm can say a lot of things for marketing purposes but my one and a half year old Note 4 has it's battery in lame conditions. Even my older note 3 (that didn't have fast charge) has it's original battery in better state and that phone was never put down to collect dust because I gave it to my brother inmediately after I got the N4. I already disabled the feature from my new note 7 just to be sure.

I have to agree with Tedkord. On my LG G5 i have 1 battery in the phone and 2 battery in my bag. I am heavy gamer and play easily more than 8 hours a day high end games on my phone. Have 3 email sync in push. 2 calender. Use the phone to make all my business call all day long and easily 2 hours or more of gps a day. Still has not been able to empty all 3 battery lol worst case i was at 70% of the third one by the end of the day. Even if some phone might have 2 time the battery life of mine using sealed battery its would still be less convenient thats my current setup. from 1% to full in 1 min as Tedkord said.

What do you do in life that allows for 8 hours of high end gaming every day!?!

Remavbale batteries aren't superior for a phone you aren't going to keep more than 2 years. I plan to replace my Note this time on a 2 year cycle. of course I tried that before and didn't hold myself to it. But I still have an S3 and S4 with its original factory installed battery. I bought an extra battery for the S3, but never used it. Its still in its original packaging. The S3/4 both still hold a very good charge and last all day still. Even if you charge your battery every single day, they don't degrade at that high of a pace.

For your need maybe. for mine nope i kill a 5000 mah battery phone in 2/3 of a day.. Ability to swap battery is very good for my needs. Its not because of battery degradation but more because when i play world of tank blitz for 5 hours in a row using chrome cast to cast it to my tv screen its eat up my LG G5 battery in under 4 hours 30 min and i dont want to have my phone plug in as i play. so i just quit the game turn off my phone swap the battery and get back in action very fast whitout any pause. you have to respect others ppl need. There will always be a place for phone thats can have battery swapped.

Yes, they are. I saw significant battery degradation with my Note 5 in less than a year. Not devastating, but I started having to charge it before the end of the day many days. Qualcomm can claim whatever they like, but faster charging means increased heat, which means quicker battery degradation. It's a fact of the chemistry of Lithium ion batteries. I experienced it.

this is the now throwaway society, dont ya know. am i wrong? smart phone is smart cause it never gets older then about 2, then gets put out to pasture. i bet it is a joke among the industry, get rid of the removable battery, they will never notice that, and the ones that regulate us dont care! wala, screw the end user is the name of that game.

Agree on the removable battery, but it seems all the major manufacturers will not make it happen again.

4. sarcastic_nerd unregistered

It just means that your test for the S7 and edge was crap. All the other sites claim note 7 to have slightly less battery than s7 edge because of smaller battery and larger screen. PA, just make a better battery test that is half consistent, or at least have some answer to explain said performance.

8. tedkord

Posts: 17456; Member since: Jun 17, 2009

It means no such thing. It means they have a different test method, that's all. Battery life is affected differently by different usage of the phone. No one test can take into account how everyone uses their device.

Actually it does mean that their test is flawed. They are the only tech site that gave the S7 Edge an average score on the battery test, and followed up by giving the Note 7 a higher score. You will not find it anywhere else where the Note 7 gets you a better battery life than the S7 Edge.
