    I have been considering replacing my Galaxy S8 battery at my local Ubreakifix store. Samsung now lists them at authorized service centers.

    My phone is functioning fine -- I've just noticed that the battery doesn't last as long as it used to to which I chalk up to deprecation due to multiple charge cycles. My Galaxy S8 is about 18 months old.

    As an added question, I am still searching for a means to determine if there is any way to tell just how much by battery capacity has degraded. Seems to me, Samsung could provide an app that would reveal this, however, we all know that phone manufacturers business model is deeply dependent on convincing folks to upgrade versus keep using an older model.

    I did not use ubreakifix because they refused to give me a price up front. I did use Batteries Plus and for $70, they did an excellent job

    Yeah, I've seen the batteriesplus $70 S8 replacement advertised on the web, but I was leaning towards ubreakifix since they are an authorized service center. Ubreakifix says they will match prices so I would imagine they would do it for $70.

    I have a Verizon S8 and I am probably going to replace the battery once I get the Pie update. I am expecting the Pie update soon and I will probably do a factory reset afterwards and then a battery replacement. Perhaps some others will weigh in....

    The app Accrbattery Pro claims to give an estimate of the battery capacity. Charge Cycle Counter is compatible with Samsung phones and can read the battery and gives (supposedly) an accurate count of charge cycles.

    is it too hard to do on your own? i'm in the same boat as OP - my battery feels like it drops way too quickly nowadays.

    There are videos on how to do it yourself -- for example ifixit. After watching one, I am hesitan to do it myself for fear of damaging the phone. I am also concerned about impacting the water resistance if I take it apart and I am also suspect that even a third party repair will lessen the water resistance. The battery itself costs $30, so I don't mind paying $40 to have someone that repairs phones for a living handle the job. I look at it as getting a new phone for $70 versus $600 or $700. I am happy with my S8.

    I am at the same junction. My S8+ discharges very quickly. Perfectly predictable actually. Li-ion batteries are a limited resource and can take only so many charges.

    I installed an app that measures voltage, that's the only true way of measuring capacity.
    4.3V is full, 3.5V and below is empty. It shuts down kind of at 3.4V or such. If you charge it fully at 4.3V and then it drops to 3.8V in an hour, something is wrong.

    Thanks for the links.

    Voltage meter.. It just displays the mAh rating, like 4120 mAh and that's all.

    There is also a fancier one, the one that showed temperate and the discharge current which I used for years, I don't know if it has a higher drain or what.

    I had my battery replaced at this Battery Plus store. Cost was $60 with a coupon.

    I am not sure that OEM is the best way to go, the "Battery Plus" place I went to install an aftermarket, it works just fine.

    For some of the older models and S8 is two generations behind, it's impossible to find new OEM batteries. Case in point Note 4 or LG V20. By definition they will be old and not holding the full charge. Even with zero cycles on them.

    I have to question this a bit, as Samsung is still selling new Galaxy S8 phones. I would assume that Samsung is still manufacturing them meaning installing new batteries in them so it would seem to me that Ubreakifix as an authorized repair center would be selling new OEM batteries. I could of course be mistaken.

    Years ago, (pre smartphone) I replaced a cell phone battery at Batteries Plus and the agent said it was "OEM quality" but not OEM. The replacement battery was CRAP....but hey, who knows as it was years ago...

    All right then...I took my Galaxy S8 into Ubreakifix today for a battery swap. They quoted me $100. I think the going rate at batteries plus is $80 and Ubreakifix says they will meet the price, however, I decided not to call them on that because they are an authorized Samsung repair center an assured me that it was an OEM battery and everything would be water proof again, fully tested, etc. etc. etc. Ubreakifix also says that Samsung prohibits them from fixing the battery only if anything else is wrong with the device -- bad headphone jack, bad fast charging, cracked screen, cracked case, etc. and they said that if they find anything else wrong with the phone they aren't allowed to fix the battery without fixing everything else. My phone was working fine, so I said no problem. But I did ask them what happens if they find something else wrong with it and they said they had to stop the battery repair unless I agreed to fix EVERYTHING. So I said if you find anything else wrong just put it back together and give it back to me. And they said no problem, they could do that and if they found anything else wrong they would put it back together and return it to me for no charge. They said it would take 2 hours. I called the location prior to going and they said that it was first come first service meaning no appts.

    So I came back 2 hours later, and the repair wasn't done. It took them about 2 and half hours. They said they would take 10% off for the delay,which I said OK. Then the guy says, "Oh by the way, I had a problem with the headphone jack, however, I got it to pass the test." I said, "Come again?". I said the headphone jack was fine when I came. I listened to Spotify this morning and made a call using the headphone jack last night and it was fine. So, I plugged in my headphones, fired up Spotify and the headphone jack didn't work! I am like, Oh ****, as I am going out of town for a week tomorrow.

    Well, so the guy told me to come back in half and hour. I came back in half an hour, and the lady apologized and said there is a problem and we admit it was our fault but the guy has to drive to another store and get a part. So come back in a couple of hours. So I am like, hmmm....OK..

    I came back in a couple of hours and the phone is returned to me and it appears to be working fine. They apologized again and agreed not to charge me for the battery. I said thanks, I am willing to pay something, as I am not scamming you as my headphone jack worked when I came in...They said the repair was no charge. I thanked them and left.

    So, on I go....I will report back once I determine A) if the repair is good and B) If my battery life is improved.

    I have come to the conclusion that essentially these super, thin, lightweight phones are just plain and simple NOT DESIGNED to ever be repaired. By ANYONE. That is probably why Apple is fighting Right to Repair. Its plane and simple that these things are designed to last pretty much NO MORE than 24 months...

    What can I say. There are many reasons for this. I don't see this changing until CUSTOMERS or REGULATORS demand that these things are DESIGNED to be repaired. Which means they probably have to be a little thicker for starters. But come on folks, would a phone twice as thick that is designed to be repairable really be a deal stopper???? Not for me it wouldn't...

    So vote with your dollars folks! If I had to do it all over again, I would have taken the $350 Samsung is offering on a trade in and get an unlocked S10E for $400. I still might....

    I will certainly re-evaluate everything before I buy another Flagship phone again. I feel CHEATED for purchasing a phone that is only designed to last 24 months. For the record I have owned my phone 18 months and it has been in a case since day 1 and never dropped in water or had anything spilled on it. What can I say. I don't necessarily feel cheated, just disappointed. More so with the way these things are DESIGNED that with Ubreakifix.

    Just my experience....

    That is precisely the truth. I am going to avoid these sealed batteries phones. As the batteries still need to be repaired, it's just an expensive and not-DIY job.

    A lot thicker - and the vast majority of customers are demanding even thinner phones, without realizing what that means. But the majority is where the money is, so ...

    They didn't make the batteries non-user-replaceable to keep us from replacing them, they tuck the battery away under other pieces and parts to make the phone thinner. It's the majrity vote that determines what they do. And the majority seems to be fine replacing the phone every 2 years and just paying another $20-$40 a month for it. After all, that's not like paying $480-$960 for a phone. (It is, but most people live paycheck to paycheck, and can't afford to pay even $200 for a phone.)

    Just to set two things straight - you can have a thin phone with a non-sealed battery, I don't think these things have anything to do with each other. I can think of some phones that were pretty thin but you could still replace the battery without it turning into a major project.

    I think LG V20 was thinner than Note 4 and LG Optimus G Pro was thinner than either, possibly.

    Waterproof - yes, you can build a device that's waterproof and has a user-replaceable battery. Take a look at Garmin GPS units, the mobile ones. They are rugged and waterproof. And take AA batteries, or Lithiums. Again, these have nothing to do with each other. It's a myth.

    The only point of sealed batteries is to make the device unserviceable so you have to take it in somewhere or just give up and get Note 11 when your Note 10 no longer performs at optimum. Planned obsolescence is the real point.

    I think if you get a nice LG V20, you can run it for years and years if you take care of it and just keep swapping batteries.
