Gs8 battery preserve 95% of their original capacities after a year. - Samsung Galaxy S8 Guides, News, & Discussion

Dont know if this has.been post before. But im glad battery degration will be minimum on this device.
"However, Samsung developed a new battery technology that will significantly diminish battery degradation. According to Android Police, the new batteries will be able to preserve about 95% of their original capacities after a year of typical use. The Galaxy S7’s battery only keeps 80% of its original battery capacity after a year."
https://www.google.com/amp/bgr.com/2017/03/30/galaxy-s8-plus-vs-iphone-7-plus-battery-life/amp/

That knowledge was instrumental in my purchase of the S8. I would not have bought it otherwise.

"... and the Nexus 6P only keeps 50% battery after a year...." #sarcasm but it's totally true... with 53,000 views on the forum and a class action lawsuit now, it's why I went to Best Buy on Saturday and paid cash for the S8....

So does anyone actually have only 5 % wear on their battery after even one year of use?

I bought my phone around the time pixel 2 was coming out nov 2017 and I already lost %5. it all depends on your usage habits in my opinion. Obviously advanced technology makes it better most of the time.

Andida 1800mAh Battery Testing

Hi All,
Well, I finally received my Andida 1800mAh battery in the mail this week. Charged it up and I'm on my second day of real world testing. It's midday over here and my phone has been off the charger since 8am although I have only used it to send a couple of messages, read a few emails and check my calendar today. I'm not using any SetCPU profiles (haven't even installed SetCPU) and I have 97% remaining.
Does anyone have any ideas on how to test this battery against the stock? I was just going to enable bluetooth, wifi, GPS and load a playlist of the first season of scrubs and see which one lasted the longest. I can't imagine either would last any more than a couple of hours.
Any better ideas would be appreciated, I'm keen to get to the bottom of this and see if there is any real world increase in capacity with this battery.

Im pretty sure this battery has no more mAh than the stock battery.
What do you mean by "mid day"?

Based on what? That's what I'm trying to determine here because although there has been a lot of waffle about batteries on this forum, I've yet to see many people who actually own the battery provide any conclusive results. At this stage I'm neither arguing for or against the battery, but testing it out.

Mid-day means 12:00PM, as in the middle of the day
Charge them both to 100% and run the same movie completely on both. See where each battery stands after the movie finishes.

Been waiting for a good reliable review on this battery, let me know how it turns out for you...
Maybe then ill be assured to buy it I cus my inspire needs more jugo [juice]...
sent from my Inspire 4G via XDA App
I'm interested to hear the results of your test. Sounds like a perfect and objective way to tell which performs better....
I have this battery and just from my normal usage, it doesnt seem to be any different than the stock battery. I have not done any testing, just comparing where the batter is after a normal day to what my stock battery was after a normal day.
Make sure you go through a few cycles with the new battery before doing anything. Also wouldn't hurt to reset your battery stats after it's fully charged. It's hard to tell what a 'normal' days use is to compare one vs the other. The movie test seems to be a pretty valid test to me. Please post your results.
i just got my $109 shipment from netimes.com with 5 cases, blutooth headset, dock with a slot for a battery to charge, and 3 1600 mAh batteries and they were all about $7 but they last almost as long as the stock battery with normal use so their probably about 1200 mAh but with 4 it should get me through a couple of days with MIUI which i get amazing battery on

Not to be rude, but that website wasn't updated that long ago with phones/batteries that are still very relevant in today's market. Considering battery technology has not gone through any sort of major rework for years it's safe to say the results on that page are pretty accurate to those phones and most new phones coming out.
Also, it's no secret that the majority of these companies rate the batteries miserably higher than what they will actually test at. I'd also imagine it's safe to say that since the testing these companies haven't changed their whole business plan to represent accurate battery measurements.
Just my two cents. We all know the general result of these battery threads.
Still those batteries on that website dint represent anything other than the phones they are for. once they do inspire galaxy s the 4 g version etc then that thing can be reference d

Until a reputable company comes out with a batter you can pretty much count on it not being any higher capacity than stock. This is due to the size of the battery, unless it sticks out the side of the phone there is almost not a way to make the battery much higher capacity using the same technology.(cheaply) Do you have evidence to prove otherwise? I'm willing to bet you do not..
do you have evidence it cant?
The evidence is in the battery capacities available, not hard to show that.
that is no evidence.......ive seen aa batteries mAH ratings grow but no physical changes.
but that is beside the point until battery boss is updated with the newest phones batteries then it shouldnt be used as a guide like it was back then

Battery Capacity Expectation

I searched this before posting, but the thread had no replies from January so hoping I can gain some insight and clarification on this.
I am new to Android and avoided it for a long time due to being perfectly satisfied with my Blackberry Q10. However a few years ago, I was intrigued by the original Pixel and knew whenever I switched , if I went Android it would be a Pixel. It ended up being a Pixel 2.
I say this because I spend a lot of time googling and researching before i ask a question to make sure i am as familiar as possible before i ask something that can be found just as fast on my own.
That being said, i can't find an answer to "What is a typical capacity loss over a number of months...?"
I just got the phone in January. Didn't know anything about capacity until i noticed a huge drop in expected battery time after unplugging my phone. It used to be 21-23 hours expected from 100%. Now its only about 10-15 hours, depending on the day. Researched batteries and learned about Accubattery. Looked at the health and saw i'm only at 2284 our of 2700. It says GOOD health..but is that really good health after only 3 1/2 months? Also..unfortunately i have no idea what the original real life capacity was because i never checked until End of March when i discovered Accubattery.
Just wondering should i return the phone or accept this level of battery. At this rate..does't seem like I will get through a year on this phone.
ADDITIONAL INFO - I have used 3rd party charging cables (Nekteck)and Samsung bricks. The cables give me roughly the same amount of juice as the charger that came with the phone ( around 1300 Mah max, more juice if I'm charging from a lower percentage start point )

Stop apps from running in the background. Your WhatsApp, Facebook, Marco Polo, weather widgets, etc are using your battery.
Sent from my Pixel 2 using Tapatalk
I don't have many running in the back. I don't have Marco Polo or Whatsapp. All my others I shut down to and when I check apps are using very low percentage. But my question is more the battery health reading. is 2200 healthy after 3 months use?
Is the phone battery actually draining twice as fast now or is the battery reporting just wrong?
The phone seems to behave normally, but being I'm not an Android user for long I don't know what normal is. I know things differ phone to phone. If I use my screen and read articles the battery drains fast to me. Compared to others who consider reading as light use. I get "better" life if I watch videos. I suppose because I'm not touching the screen. Streaming I can do for hours. I think what I'm trying to understand is...how accurate and important is a battery capacity reading? Should I be concerned that it says im only getting around 2200 out of 2700? For an almost phone I would think the capacity would be closer to the design capacity?

Is OP6 battery really 3300...?

Hi, just wanted to ask if someone else beside me and my friend got a 3000mAh battery (According to accubattery) after a couple of months, the same happened to another friend of mine with a OnePlus 6T, 3450mAh instead of 3700mAh.
Screenshots attached.
Accubattery is insanely inaccurate, and takes an estimated guess based on charging cycles. Long story short, the app is garbage and people should stop putting faith in it.

I've already tried to search for a this app, and I found a thread in the OnePlus 5T section where a USB multimeter in, at least, two cases, has shown the same result as Accubattery.
Anyway thanks for the answer, need to find why battery sucks su much on both my friend phone and mine.
I experience the same issue !

I experience the exact same issue on my oneplus 6. The accubattery app shows my battery health as 3,046 mAh and design capacity as 3,300 mAh. It has been this way since the day I got the phone (around one month back). I am pretty bummed that oneplus sent me a phone that had only 90% battery life to start with. Is that a problem with the battery or is that a problem with the way the accubattery app reads the results?

Seriously? As stated before it is a calculated capacity. It measures how much goes in and out. While the battery is shipped as 3300 mAh the app can very well vary as it is only roughly calculated and the full capacity is very theoretical as the voltage decreases and is never zero.
You start with 4.35 V = 100 % and end at maybe 3.2 V = 0 %. So you have energy left after your phone as shut down. That's why you get a battery low screen even if your phone has shut itself down. It is not a design flaw and it is not scam.
Also don't forget that different components use different voltages. Transforming them results in wasted energy. Like a power bank that has 10000 mAh in theory only can charge maybe 7000 mAh while the rest is lost in heat.
thank you !

thank you for your detailed analysis !
It's kind of reassuring because when I bought mine it was second hand and I saw around 3000mah as well! So actually the battery wasn't damaged probably.
It could also be OnePlus which makes the choice to not allow the phone to charge completely so the battery lasts for longer in long term. I Kno Dell does it for example. Then it would be very acceptable. But yeah, maybe it's the app.
Had the same issue with several phones, for example with the S8+, Accubattery showed 97% from day one, after a few weeks it dropped a bit lower still.
The app seems highly inaccurate and I quit using it.

Show your reported battery capacity (Exynos)

As I have not found a list of user reported batter capacity I thought, let's create some insight so here we go!
Accubattery shows on my 1 week old Exynos ultra battery only has 4041 mAh capacity
What about yours?
You can't figure out the capacity of a battery after two partial charges.
Why do you need these figures? My sm-n9860 shows me the ~20 hours TTL after the full charge (stats are based on the heavy browser's usage) - TTL is the only useful indicator I guess.
I know that 2 cycles is not enough, that's not why I started this thread.
It is interesting to track capacity degradation over time. If everybody reports there figures every now and then, providing insights on that could help people identify battery issues. Although with all the different measuring app outcomes it will not be an exact sciense but an approximation.

Here you go if it makes you happy I don't mind participating.
Day 4 of ownership. And one day after a factory reset.
The Note 20Ultra's battery has a kernel charge limit of 4060 mAh -100%. So it's not about 4500 mAh only 4370mAh with limitation. I will never understand these huge differences recorded on Samsung batteries between the declared minimum value and the value recorded on charging.

I see that you partially charge your phone 40-80%.
I don't know if this partial charge will really extend your battery life. At Samsung I have seen over time that the situation is upside down and the charging counter is misled from where and sometimes a strong drain. If this partial upload by Samsung were supported by the software, then it would be a good thing otherwise I don't see much. As with Apple, Sony, Oppo ..

I always partially charge my phone approx 40-80 sometimes higher l, sometimes lower.
Samsung batteries seem to have a some sort of reserved area that doesn't get used until a certain degration is reached. That's my hunch.
PS I got an SD n20u now, no different to exynos ?
From my experience in the past with these battery monitoring apps the battery health measurement is pretty innacurate. When I first got my 20 Ultra it said the battery was at 94 percent health which was definitely wrong.
Same in s20 and s20+.... the charge stoped in 3600 and 4076 respectively... great work samsung

38 cycles and 99% health by accubattery.PhoneInfo
says something else I suspect depending on the kernel limitation,93,6% health.
The best way to extend your battery life is to switch your phone off at night. Lets estimate a 33% longer life assuming one sleeps 8 hours a day. 33% for free!
In the mean time my estimated capacity is up to 4370mAh

Question A73 Accubattery Health

Hi guys. Just wanted to ask a quick question with regards to. My Galaxy A73 and the accubattery health estimate.
Before anyone yells from the tree tops "battery monitoring software isn't accurate" I know that, but it's enough to get a general idea on how my battery is holding up. And historically it's readings have been pretty good with me. Recently slapped in a fresh 3000mah battery in my S7 and it pretty regularly reports the battery health in the 96-98% range (I typed in the correct capacity for the new battery) which I am happy with. So..... with thay out the the way!
Recently the entire family basically came up for new contracts all at the same time, and we all got A73s. So three phones for the wife, father and myself. I've installed accubattery on all three phones and done full charges, ~15%-5% up to 100%. And on ALL three phones the reported battery capacity is around ~4500mah which seems far off of the design capacity of the advertised 5000mah. My particular phone reported a first charge capacity of 4733. But has dropped to 4500 over subsequent charges. As I said. I know software isn't 100% accurate. But historically it's been good to me reporting good numbers for my S7 and my A80.
Although I have been very impressed with the battery life thus far im still wondering if these battery's are bad.
Can anyone else show their accubattery results?

Interesting.
So you are also seeing ~4500mah?
Well of that's the case then I don't think all these phones can have bad batteries.
So Either
1. Accubattery is reporting incorrectly. Not exactly far fetched as software can definately be wrong.
2. Our phones all have bad batteries. less likely but still a possibility.
3. Or lastly Samsung is lying about advertised capacity and we all have 4500mah batteries. I find this to be the LEAST likely scenario.

Sorry this is an older thread, but I've had much the same issue with quite a few of the Sammy devices, and found this thread because I've been considering an A73.
First, Accubattery, in my experience does a good job. I've used it on an LG G8 that I had done battery 'conditioning' since it was new. Guess what? Accubattery rated that phone at 103% of capacity! Yes, it was accurate. Also used it with a Pixel 6a and battery was 100%, so that one was rated at 4500 mah and that's exactly what Accubattery said.
But most of my Sammy phones, like the 2 A52S I have, are rated much lower than stated capacity. Instead of 4500, they both rated about 4100.
Your scenario number 3 is actually correct, but not in the 'lying' part. If you research it, ea mfg tells you that battery capacity can vary (they claim it's hard to control during manufacturing), and it states in their 'fine print' that a battery actual capacity can vary by 10% plus or minus (it's always minus).
That means my new phone, properly conditioned from the beginning, could read as low as 4050 and still be within specs. So it's not a 'lie', it's a way to put in less battery and still claim it's 'as designed' and you have no recourse.
Ironically though, my older galaxy A03, which has a 5000 mah battery, gets a 100% capacity from accubattery. Sometimes I think it's a better idea just to use them and not even think about it. It's kind of tedious and it's pretty much out of our control. And life is short.
cheers
