Since i always post the same problem, battery life could be better, will probably get 8-9 hours, with 3-4 screen time. Gonna keep it stock kernal so its more stable.

i think 2800 mah battery not enough for daily usage

It's 2600 mAh, not 2800 mAh. And why do you think it won't be enough? They're probably making AMOLED even more efficient than it was last year and the new Exynos SoC is up to 30% more efficient than current offers because of the 14 nm half node.

They are slapping power user in the face with non removable battery. Now instead of carrying spare battery I need to bring a chunky PowerBank. Can't Samsung realize they are not apple and they abandon their core audience do them no good?

is it not possible to insert 3000 mAh battery to s6? it won't be more usefull for users? why samsung still parsimonious? s5 has 2800 mAh battery & s4 has 2600 mAh battery and s6 will come with 2600 mAh battery. sometimes i can't understand to Samsung.

Like I said, if these rumors get confirmed, it's quite possible that the GS6 will perform better than current smartphones, even with a smaller battery. Which in that case allows a slimmer, lighter device.

If the phone is getting a QHD Screen I doubt that there will be any better battery results than the other mainstream smartphones.
Just compare the Note 3 vs Note 4.
What about a poll with:
a) I want a phone slim like a post card with 3-5 hours SOT
b) I want a phone slim like a S3/One/Lumia with 12-15 hours SOT

It seems like a non removable battery with 2600mAh

The QHD on the Korean S5 LTE-A had about the same battery life as the US variant. Therefore, the QHD on the S6 should have the same...if not better battery life even with a smaller 2600 battery. I wouldn't worry too much about...my only complaint is that it'll be non-removable

i see bro. thanks for your explanation. i think you will buy a GS6 when it available for users

Since S6 was said to use Exynos7420 instead of Qualcomm........the consumption of cortex A57 would exceed A15 and Krait a lot according to Anandtech

I'll take Option C. A phone that is 12mm thin and has more like 20 hours of SOT.
There's no point in making super powerful smartphones, if we can't use them like the pocket sized PCs that they have evolved into. I'm sure there are many people who would love to use their phone to get actual work done without having to worry about the battery. Also, since batteries wear out over time, I'd rather have a bigger battery than what would seem to be big enough at first.

Because the CPU/GPU only within the same generation range on 1080P(note3) and 2K(note4) though on paper spec. the latter one should be a lot better but still same generation and indeed that kind of power isn't enough to push 2K. Hence, the CPU/GPU will always require to run at a higher clock and battery draining even just on 2D.
S6 is running a whole new CPU with 14nm manufacturing process, the situation should be much better though but I agreed 1080P is enough on a tiny screen and I also prefer more battery life.

Is the battery removable?

I don't think so

The battery will NOT be 2600 for the MILLIONTH TIME. IT'S ANNOYING ME HOW blind all these websites and you lot are. The info is right in front of you the batteries were for G925 WHICH IS THE CODE FOR THE S EDGE. NOT S6
SO WHAT DOES THAT MEAN? S6 WILL BE MORE JUST LIKE WITH THE NOTE
NOTE 4 BATTERY 3220
NOTE EDGE BATTERY 3000
NOW STOP SAYING IT'LL BE 2600.

Its funny to see how rumors, leaks and teasers mess with people's brains and expectations, the media really knows how to get in your heads. We will know by sunday's time, then all of you will really have something solid to criticize until the next device comes up, so just hang in there. I just hope it lasts me the whole day on moderate use, so that I can charge it overnight

Butthurt much?

Battery size difference of 200 mah is meaningless. What matters is actual battery performance. Is there a correlation? Sure. Does every phone last same length of time with the same capacity battery? Hell, no.

We will see next week.

S8 vs S8+ battery life comparision

Anybody find any links to S8 vs S8+ battery life comparison​? I want the S8 for size in my pocket and easy to reach fingerprint scanner. Want to see tests of the S8 vs S8+ vs S7 Edge battery life comparison...

I cancelled my preorder to wait for battery life reviews, bigger screens and higher resolution and same sized battery (smaller for s8+ than s7e) doesn't seem like the processor will be able to offset the drain. And also wondering if the exynos will be more efficient with battery life than sd as last year was. I use to have sd820 s7e and now I'm using international exynos s7e and do wish I originally bought the international one

Phone arena did some testing and found that it comes out on top over the S7E. It also beat the Pixel XL and Oneplus 3T. Of course people need to do there own testing to be sure.
It's not just the SoC being more efficient that can save battery. Displaymate.com have noted that the panel is not only better but also more energy efficient. The software is no doubt better optimised and that can also mean battery savings. Anyway, in the tests in ran for 8 hours which isn't bad. Add fast charging and it's fine for most people.
Next time I do hope they increase capacity, I don't want slimmer phones, I would prefer a larger battery. We never seem to benefit from improved power efficiency, it's always more of the same. They have supposedly improved the battery tech in the S8, it should hold charge better over time. We might only lose 5% over a year instead of 20%. That is better in the long run.

I think they purposely made the battery small to prevent the chance of phone explosion, that is absolutely the last thing they need right now and I don't think they want to risk that., but I'm rooting for the s8/s8+ to have great battery life. I'm hoping the battery stats r near identical between the two models so I can get the smaller s8 and not feel like I got jipped on battery life, and I read some early test that the 8895 exynos will be better than snapdragon.

Want to know the PROS and CONS of the Samsung Galaxy S8's battery

Hello everyone,
I want to know the PROS and CONS of the Samsung Galaxy S8's battery. I am currently a Samsung Galaxy S7 user and I am thinking to make an upgrade. I always wanted a phone to have a heavy battery life as I am a heavy user.
Also let me know if the phone charges faster compared to the S7.
Thanks in advance, it is my first time posting here

Hey Shajjadur,
Welcome to the XDA!
The Galaxy S8 charges quickly, not necessarily any faster than the Galaxy S7, but 15 minutes will give you circa 20% battery life, almost 50% in around 30 minutes and a full charge takes about 80 minutes. Wireless charging isn’t as quick, but it still charges far faster than an iPhone.
Here are pros and cons -
Pros: Better than it should be, fast wired and wireless charging, promises of long term safety and performance
Cons: Disappointing battery capacity, reduced resolution required for all day stamina, generationally a backwards step

S7 battery capacity after one year is 80% of new. S8 battery capacity after one year is 95% of new according to Samsung.

I got a killer mobile battery charger can do at least 5 full charges so never concerned anymore about battery life lol.
Example used my phone all day yesterday. Took pics used net etc and did small chargers now and then kept me alive all day and night.
Also it's fast charge too.

Battery life on the S8?

I have owned the Galaxy S7 Edge ever since it came out and although I've used many, many phones over the years, both iOS and Android, I can say with absolute certainty that it is the best phone I've ever owned.
Unfortunately, the screen developed some sort of a pink line recently and I cannot do anything about it since I am not under warranty anymore, and I rooted the phone when I first purchased it so the warranty was voided from the start.
I am currently in the market for a new phone to replace it and my gut tells me I should go for the S8 even though I know it's not totally different and might not feel like a "new experience", however I already love how the phone looks and of course the performance on the S7 itself is stellar, so I'm sure it'll be even better on the S8.
My only concern is the battery life, though. I am targeting the regular S8, not the S8 Plus, and I read that the battery is 3000 mAh while the S7 Edge's has 3500 mAh and a smaller screen which is absurd! I don't want to have to buy the Plus for the battery because it's just too big, so what do you guys think about the battery life on the regular S8, at least in comparison to the S7 Edge's?
Thanks

I had a G930F S7 Exynos before I switched to the G950F S8 Exynos. The S7 I usually got around 4.5 to 5 hours of SOT with location, Bluetooth and 75% display power. On the S8 I'm currently getting 7.5 to 8 hours SOT with the same setup. Mind you I have sync and wifi off at all times.
The S8 is a great phone. Though I can't judge the snapdragon since I have the Exynos model.

@chungdae Thank you for your reply. I have the Exynos version as well, we never actually got the Snapdragon version over here. That sounds really good and now I feel a bit better about making that decision. I feel like 5.5 to 5.8" screen is a perfect transition, whereas 6+ is just way too huge.

Yea in my opinion the size of the S8 is perfect the plus was just too big for me. There's a lot of tweaks you can do if you want to squeeze every minute of screen on time but for me it wasn't necessary. Most people receive 6+ hours normally

I used to try all those different kernel tweaks and such with the S7 but I realized they were doing more harm than good, so I just let the default settings be and things have been good ever since.

I haven't used the S7 Edge, but I'm really happy with my S8's battery life (I have the Snapdragon variant).
I get around 8 hours of SOT, and can leave my phone off the plug for at least 24 hours, if not more when used less frequently. This is on stock, with a few things disabled (Lookout, some Samsung apps).
Here are some photos.

I have no idea how people are getting 8hrs SOT on the s8+. I'm lucky of I reach 5hrs. What are the secrets? I have Snapdragon version btw

I have around 9 hours screen on time on stock firmware, really happy with result.

Huawei Mediapad M5 Lite 10" vs Samsung Tab S2 VE T813

Hi Guys,
Been searching for a cheap tablet with reasonable performance to run around the house, what's your take on these 2 options?
pros and cons?
My own opinion:
The recently released the Huawei has a better and modern layout / design and a fresh battery.
The Tab S2 has better screen, better performance.
About the same price at the moment.
Any help would be appreciated.

Similar to the m5 lite there also the galaxy pad a8 2018, but unfortunately lack of fingerprint reader...
Tapatalked with A8 2018

There is probably lots more support for the Tab S2 if that's important to you.

I bought SM-T719 last week for 299Eur. Nice small tablet. Amoled is great, came with android 7 preinstalled, battery has no drain when idle, is fast, LTE did not try yet.
EDIT : the battery life : I still had 80% battery left after 95minutes of browsing (on-screen time), so that makes the battery life 475 minutes, or almost 8 hours. I have the tablet on for couple of days. That is very good battery life.
