    Having a phone sit at 100% on a charger means it's not discharging. This means electrons aren't moving. And this means wear on the battery is at a minimum. Unless you have an app that can hold the charge at the ideal SOC, chances are you are going to oscillate around it. Which causes more wear on the battery. Battery wear is generally most dependent on charge cycles. Which means holding it at a SOC is better for the battery than trying to maintain a range.
    This is incorrect, as simply being at a high voltage shortens their lives as well. I used to do like you and kept mine charged almost all the time. My battery was toast in 6 months. This article has some great info on this and other charging habits.

    One paragraph of note on this topic:

    Besides selecting the best-suited voltage thresholds for a given application, a regular Li-ion should not remain at the high-voltage ceiling of 4.20V/cell for an extended time. The Li-ion charger turns off the charge current and the battery voltage reverts to a more natural level. This is like relaxing the muscles after a strenuous exercise.
    Note that the 4.2V cutoff it mentions is a little outdated, as advancements are now allowing batteries to charge to 4.4V. Still, it's not as simple as counting cycles. The voltage levels themselves can hurt a battery. Too high and too low will both cause issues, and is why batteries are shipped with a partial "storage charge."

    I don't disagree that holding a partial charge can be better for battery life, the fact is charge cycles do make a difference. It would be more ideal of you could have a function that holds the charge at 80% while changing overnight, but no such function exists. For most people, I think holding at 100% overnight will result in better life than discharging from 80% to whatever it ends up at.

    Yes, cycles do count, but it's not the only factor as your earlier replies claimed. For a sealed battery, I'd do everything I can to prolong its life (though I own a V20, so this isn't as critical for me). Cycles, dwelling at high or low voltages, temps, and simply time all play a role in battery life. If you are keeping your battery fully charged almost all the time, you are damaging it, more so than cycling it between 40-80%. Li-ion batteries prefer a happy medium in almost all aspects.

    If you really must have a full battery to start the day, I'd charge to about 80% before bed and let it stay there over night, then top off in the morning while getting ready for your day. That will at least limit the amount of time it's held at a full charge.

    Yet leaving it on the charger at 100% doesn't damage the battery so charging to 100% isn't going to make a difference.

    I charge it over night every night. I envy those who say that they can get more than a days charge and over 6 hrs SOT. For me on average I get about 3 hours SOT. so I have to always charge it up over night. it must be my cell signal with AT&t. all the phones I've had in the past (iPhones and Android phones) never lasted for more than a day.

    still waiting for that phone which will give me 6 hours SOT, but I came to realize that that may never happen

    Once everyday overnight, sometimes once every 2 days depending on usage. I leave it at 100% for a few hours as its only takes what 1-2hrs to do a full charge from about 20%, always done this always will, never had a battery issue (Touch wood).

    Getting epic batt life on the s9+ exynos usually 24 hrs uptime and 4-5hrs screen on time or more.

    People who are gettting 6-9hrs screen on time and 24hrs uptime are usually more than likely shutting off all data/wifi/notifications when the phone is asleep and/or watching vids/reading ebooks for hours to boost their SOT for bragging rights on the internet

    I have location on battery saving, mobile data always active off, device search off, wqhd on, Bluetooth and wifi search off,did gaervicefix 3x, brightness at 30-35%, yoru for substratum. I turn off Bluetooth and wifi when not in use and I have nfc off. I turned off most things for notifications and I do have aod on on the middle brightness. Intelligent scanner is off as well.

    My point is my 2xl hits 7+ hrs sot before 20% and it's on 1440p display as well. Sigh,
    Funny enough my note 8 actually hit 8hrs sot quite often before it died but 7hrs as well sot before 20% at 50% brightness with wqhd. So idk

    I think it may just be the att firmware, my note 8 wasn't on the att firmware so maybe that's what it is.

    So I had a 7 edge and had to charge at work every day my signal isn't that great with Sprint. But I loved the phone and always had a charger with me. Got the Note back in December never had to charge my phone at work anymore I loved it. I don't turn stuff off just to save on battery stuff I use anyway. But I work 2nd shift and every night phone sits on the wireless charger. I wake up and when I get to low 90's or 85 or so I top it off and like to be in the 90's to a 100 for work and after 8 hours and I am on wifi my signals not the best I leave work with maybe 30% or less. Well last week after the Oreo update it seemed to me I was getting better battery leaving work with 40-50% and was like that's good.

    Than on Sunday I sold the Note and got the S9 plus. I was off Monday but Tuesday I left with maybe 20 something% I wished it was better but as long as I didn't have to charge it at work I was happy even though I keep the charger in my purse. Last night I left with 32% but I haven't fully tweaked my settings yet but am open for suggestions.

    I have wireless chargers in my house too so like now I have it sitting in the charger its at 95% been up since 10am and haven't done too much on phone am on my computer. My NFC is off but me and my husband had our Note on the highest screen resolution WQHD and the night I came home with 20% I happened to check and mine was on FHD and I said to my husband which one did we have our Note on and he said WQHD so I changed it. I keep location on battery saving mode and I use Bluetooth with my Gear S3 watch.

    I haven't looked at email settings yet but on older phones I would have it said not to check too quickly or mostly just download when I open mail. I do use AOD I like it and I like I said I won't turn stuff off just to save on battery. My 7Edge I had a quick charge battery pack on the Note 8 it wouldn't fast charge I found out I needed a 3.0 one but never really needed one cause of battery being so good. Anyway I just got my S9plus so I was browsing the threads here. Haven't had the phone long enough but am curious what my battery will be at tonight when I leave work. I also am using Intelligent Scan I like it. But if their is other stuff I can do let me know but I don't turn stuff off I got the phone to use it. Oh and mine is unlocked.

    I charge overnight and once a day, I use around 125% a day.

    With the note 8 it was around 160% so I can charge a little less with the s9+ but still won't last a day

    As with every subject there is way too much info out there. I don't mean to say less info is better, but there are just so many opposite opinions it can be difficult to figure out what is better advice. I'm seeing fairly consistent info that says, do NOT charge your phone overnight when you're sleeping. I'm seeing that they kinda recommend not to charge past 80%, and that will add major life to your battery. I split the difference and charge to 90%. I'm not a power user and carry a small power bank with me, so I'm not concerned of having a phone with a dead battery at any given time. The newest tidbit I picked up was to go through the procedure to get "developer options" look at the running services and see if NON necessary apps are running at say, 75mb+. For me it was an app I had for a wake up alarm and it was consuming 121mb. I uninstalled it and presto, my battery drain stopped. I was beginning to think my battery was on it's way out because it's two yrs old, so I was happy to see that I wasn't going to have to pay someone to replace the battery in my S7. My new S9 is just fantastic in every way especially battery life. I'm not using it a lot yet, so I'm going like 3-4 days on a single charge. Oreo seems to play well with the S9. I get the message bubble etc, etc.

    Just throw mine on the charger when I want to. Will probably get another phone before the battery dies. This 40%-80% is too damn complicated. I think there are some people that just overthiink every thing, and that is great, but not for me.

    AOD sucks it down. I turned that feature off. Don't really care.

    Today I've had 3.25 hours voice calls, 1 hour 9 minutes screen on, and the system tells me I've been running it 12 hours since I unplugged it this morning--and at the current rate, have a life of 14 hours left.

    I can extend that 14 hours to 48 hours if I use the "max" power saving mode.

    I use the AOD and like having it on but yes it does chew up some battery. In my case when I’m at work my phone is on my desk and when home it’s on the table beside me. I generally keep my phone face down so the AOD is off and just turn it over when I want to check it. That way I get the best of both worlds, use of AOD and save some battery at the same time.

    Yeah. I noticed that the battery last a little longer with it off. Even though I do really like AOD. So I've had it turned off. And I'm just using LED indicator. Because it eats up less battery.

    I have an S9+. I've only owned it since Monday so so far, I've only had to charge it once and it's still at 51%. When I do charge my Samsung phones, (S7 Edge, Note 8), I either fast charge them or plug them in if I want a faster charge. Many times, I leave them on the charger for a day or two and it has never ruined my battery doing this and I've done this with every phone going back to the original iPhone in 2007. I just say, charge the phone however you want. I charge mine to 100% and let it get down to 5-15% before I charge it again.

    I charge mine overnight as I've always done since I've had cell phones. Never had any real battery issues with any of them except for the occasional defective battery from the start. My wife and I both got a new S9+ about a month ago. Hers was great and mine was horrible for battery life. I could watch the % drop quickly doing nothing. I ended up returning it for a note 8, but the 9+ was really the better fit for me so I returned to the S9+ on Saturday. This one is much better than my first one. I'm getting solid battery life. I charge overnight and so far I'm at 35-50% at bedtime after a 16 hour day of use. I don't use wifi very often due to no good home internet options where I live. If I had wifi at home it would definitely help my battery life. I leave everything else turned on since I use it most of the time. Overall I've been satisfied with the battery. I know they say the batteries are happiest between 40-80%, but to be honest it's more stress than it's worth to worry about it. I just charge overnight and know I have enough battery to go all day. On the off chance it's a heavier use day I can do a fast charge top up and be good to go.

    There is an app called Phone INFO in the play store. The latest version now shows the current amount of charges battery has and the current battery health.

    Since my S9+ is new and still hasn't been through a complete discharge yet, it doesn't show the correct capacity yet and still shows o cycles.

    Here is a screen cap from my Note 8 that was bought on launch day. MY capacity shows 98.91% after 113 battery cycles. That is excellent. This is after charging it from 5-15% all the way to 100% each and every charge. This is why I don't pay attention to those charge to 80% sites.

    I edited out the screencap because it shows my serial #.

    I have to charge mine twice a day or more. This used to not be the case until the June T-Mobile update.

    Now Android OS takes the bulk of the battery percentage which is not normal.

    Can someone help me figure out how to fix this? Thanks!

    During the week, I generally charge once a day. I throw it on my old slow wireless charger next to the bed so it's full in the morning. It will usually last me all day during the work week. On the weekends, I often have to give it a boost in the middle of the day since I use it more when I'm not at work.
