Galaxy S9 and S9+ batteries allegedly revealed... don't get too excited

Galaxy S9 and S9+ batteries allegedly revealed... don't get too excited
A large battery — that's every phone owner's dream. But manufacturers also want to make their devices slim and elegant. So, there's a fine balance that needs to be struck — make the device thin enough but don't sacrifice too much of its battery life. Samsung's Galaxy Note 7 is a perfect example of why one should be careful with this balance — the device had too small a compartment for its battery, which was sort of the general reason behind the whole exploding Note debacle back in 2016.

So, with the Galaxy S8, S8+, and Galaxy Note 8, Samsung played it safe and didn't go with crazy capacities or anything. The regular S8 had a 3,000 mAh cell, the S8+ sported a 3,500 mAh one, and the Note 8 had a 3,300 mAh juicebox. Lots of powerusers were disappointed at first, but the phones turned out fine, capable of holding their own in the battery life category. Still, many hoped that Samsung would pack bigger cells in its 2018 top-tier phones.

Alas, that may not be the case.

A recent leak claims to show the batteries that will be going inside the Samsung Galaxy S9 and Galaxy S9+. The leak is nothing too fancy, really — we just get a few photos of each battery from a few different angles. What's important here is that we can clearly see their capacities printed on their labels.

Sure enough, the Galaxy S9 cell has a 3,000 mAh capacity, while the one meant for the Galaxy S9+ is shown as a 3,500 mAh one.



Now, a leak is nothing certain, so take it with a grain of salt. But, judging by everything we've seen about the new phones so far, it seems their form factor will be very, very close to the one of the Galaxy S8, probably with slightly slimmer bezels. As far as we know, there's no way to install a portal to Narnia in the back of a smartphone and fit a 6,000 mAh battery in it, nor has there been a recent breakthrough in battery construction that would allow a larger capacity in a smaller body.

So, this might very well be legit.

Still 3000mAh pathetic Samsung 3200mAh minimum the screen uses the most power for most users.

Tell that to apple. I can't even drain my s8 on a day of heavy work, my sister's s8+ gets charged every 3 days. Having bigger capacity is good but s8's battery is not pathetic.

Really unfortunate Samsung didn't up the battery size. With my mate 10, i have 4000mah and have the best battery life ever experienced. I'm averaging 9 hours of SOT and has been as high as 12.

So its obvious you can get more gas mileage from a Prius than a Lexus RX. No surprise. When you try to compare a phone that does less, with one that does more as far as battery life, then it pretty much proves you aren't considering the differences in capabilities and how they may use more power. Which means you are avoiding the obvious. When phones have quick charge capabilities, battery life simply isn't an issue. Samsung batteries don't need to be bigger, now does the phone have space for them.

Did you notice that each year Samsung battery got smaller but last longer. Wait until they bring out that Graphene technology and Samsung will rock even smaller battery and last 5x longer.

You must not be familiar with the mate 10. It's a legit flagship. It's not a midrange device.

There’s nothing wrong with the batteries. When I had my S8 last year, I charged in once in the morning and pretty much didn’t have to charge it again until the next morning

200mah aint gon make much difference. If you're going to make that comment you made, at least say 3600. lmao

Had great battery life on my S8+, have great battery life on my Note 8 now, and will be looking forward to great battery life on the S9+...

I easily get 24-28 hours on average with my Note 8. Not sure why people are complaining so much. Don't like it, buy a different phone.

Some just want nuclear reactors in their phones. They have to wait 'til the graphene battery technology kicks in.

Because everyone doesn’t use their phone just like you do. That’s why we complain.

I don’t have a Galaxy Note 8....genius. By the way my comment was in favour of every phone owner, not just those with the Note 8. That’s why I wrote “we”.

Of course you don't have a Note 8, let alone any Samsung phone, I'm sure we have already figured that out based on your lovely comments you keep on posting on any article related to Samsung. And no, you did complain because it's a Samsung device. Your other comment in this thread shows your famous bias against them and towards Apple.

Of course you are gonna say this. It’s human psychology when someone tries to defend something rightfully, people think that guy is biased and hates the thing he isn’t defending. And it’s all the more evident in case of Apple and Samsung. I’ve seen and argued with people like you, but to no avail. So I won’t do that again. Because I know you and some of those like you make great comments many times. It’s just sometimes you guys think that all Apple defenders are iHeros who have no life. And you guys would never believe me if I told you I have defended other brands in the past too, such as Xiaomi, Huawei, and even Samsung. I hope it clears your mind about me. And makes you believe some people have a life. And prevents you from being Supah or cnour.

" It’s human psychology when someone tries to defend something rightfully, people think that guy is biased and hates the thing he isn’t defending." Very true and accurate. If you say anything bad about any brand, even if what you are saying is 100% true; you are a hater or you are biased against or for another. AUTOMATICALLY. But in this case of the battery, if you don;t own a Samsung phone, then the fact of whether or not the battery needs to be bigger to begin with, shouldn't matter to you because you don;t know what is the expect life of the device. Broadly we all would love bigger cells in out phones. Phone that have fast charge don't need them. Especially when you consider that in 30 mins from zero, you can charge at least 40%-60% of the battery and that just an 70% charge of the latest Samsung phones starting with the S6's will land you more battery capacity than Apple devices.

THIS is the most accurate answer. Because no one here complains about the other premium phone, which sells for a much higher price, and had a sub 3000 battery in BOTH models. When Samsung has shoved larger batteries in devices of the same or lesser size.

People were crying about battery capacity when the specs of the S8, S8+, and Note 8 were announced, yet Samsung were able to deliver better battery life than their predecessors. That's why I'm not concerned at all with these numbers, I'm sure with the new chip, and Samsung's optimization, the S9 and S9+ will have a better battery life than the S8 and S8+.

Hi Maherk. I see your point, but I think people are upset because imagine if they simultaneously increased capacity while making processor optimizations. You might literally add about 2-3 hours of SOT on top of whatever improvement there was.

I am not saying a bigger battery isn't welcomed bro, but Samsung learned their lesson, they are not going to cram in a bigger battery in a phone that is tight on space. Who knows, maybe if they got rid of the heart rate sensor and bixby button, maybe they will be able to increase the battery size by at least 100mah? I'm not sure if that's possible, but that would be the only way Samsung increases the size of their batteries without facing another Note 7 like fiasco. For me, I expected a worse battery life when I moved from the S8+ to the Note 8, but Samsung's optimizations within Android 7.1 surprised me, as I am getting at least 6.5 hrs of sot, almost an extra hour over the S8+. And I would still have between 20 to 30% at the end of the day.

maybe they can't increase battery life when you have to have other features in yoiur phones. Maybe if they remove the cameras from the back and shoved them in top the corner, removed the wireless charging coil and the NFC chip, then yeah they probably could place a bigger cell. Also if they wanted a thicker phone, it would be able to hold a bigger battery. Bigger battery also means heavier phone. Which a dual glass phone, it also means when dropped a heavier device would also cause easier breaks of the glass. If you wanna have afield day on criticizing an OEM for smaller batteries, yet have larger phones, then you can have a field day on Apple. But you don't. So when you only attack Samsung but no other OEM for the same. Then it comes off as bias, even if you have good intentions. Especially for people who actually use or own the brand of phone you're mentioning. I get 2 full work days from my Note 8 which has far more features than your Mate Pro 10. I like the Mate 10 Pro as well, but it doesn't offer what the S8 and S9 or Note 8 offers.

Come on Samsung, other manufacturers manage to cram in larger batteries

The extra 100Mah the Note 7 had over the 3500 cell in the Galaxy S is not what cause them to explode. The design of the battery had a defect that cause them to explode. If Samsung can put a 3500 in the S, that means the Note can also have the 3500 as well. The battery along with fast charge is good enough for me and many others. The vast majority of phone buyers could are less about battery size, or iPhone would surely suffer sales. Only people here want to debate things of no significant value.
