Protect battery 85%

[Msi88]

Any truth to this? So my take is we lost 15% of battery if we turn it on?

When your battery starts to show signs of deterioration you are supposed to turn battery protection feature off to start utilizing previously locked capacity.

Limiting battery charge up to 80-85% is not Samsung theory, this is commonly related to Lithium Ion batteries. This feature also can be found on the laptop battery or another phone like iPhone. To ensure battery health accurately after several years you can use a USB Power meter to check battery capacity by charging from 0% to 100%. 

If after 4 years of usage and feel get three days from charge may be the battery quality is very good so just a little bit degrade

That's also an issue, you're not supposed to let lithium batterie run to zero, I think that does damage to the lithiumbattery, once again I can only comment from my experience & mine as been a good one when it comes to charging the battery from 20-25% to 100%. I can't speak for anyone else's experience only mine & I've owned many different smartphones without any noticeable battery health issues.
Once again I have my s9 still getting two to three days battery use & I bought mine from the release date.

Yes I know, there is a bad idea to let the battery to 0%, I only suggest it only for checking purposes only. Yes maybe each people has a different experience, my point is limiting battery to 80-85%, not Samsung theory, the theory also common like letting battery under 15% is bad. And also my wife often let his phone at almost 0% but until now still fine. Because we don't know how big & when the battery will degrade and the accurate method we can check it using USB meter while charging.

[Blessed4life]

Well once again you're proving my point, if they say running your battery to zero percent is damaging to lithium batteries & your wifes battery is fine, it's the same with charging my battery to 100% & it being fine, I can only go by my experience.
You know what they say, If it ain't broken don't fix it.

There's AccuBattery app on Android and it did a good job at telling me the status and capacity of smartphone's battery that I used for over 3 years. I do have USB power meter though.

[TerenceStanley]

Can I limit my note 9 to stop charging at 85%?

[Jack_Silver]

I'm not sure if it has that feature 

But to see if it does, search for "protect battery" in settings

Каждый раз при зарядке ты будешь не получать 15% энергии, но когда нибудь потом сможешь воспользоваться тем что сэкономил 🤣

Как по мне, так этот режим актуален для тех кто часто держит телефон на зарядке, к примеру, оставляет на всю ночь, или ездит в автомобиле с подключенным телефоном к бортовой сети. В этих случаях, батарея телефона много времени проводит с постоянным зарядом в 100%, что фактически соответствует, что она храниться с зарядом 100%, что как известно не очень полезно, батарея должна храниться с зарядом в районе ~80%. Если телефон не остается долго подключенным к зарядному устройству, а сразу после заряда отключается и начинает использоваться то смысла заряжать до 85% особого нет.

My trusty translator has advised that, @Red_Wan, has posted the following:

"Each time you charge, you will not receive 15% of the energy, but someday later you will be able to use what you saved: rolling_on_the_floor_laughing:

PS

As for me, this mode is relevant for those who often keep the phone on charge, for example, leave it overnight, or drive in a car with the phone connected to the on-board network. In these cases, the phone battery spends a lot of time with a constant charge of 100%, which actually corresponds to the fact that it is stored with a charge of 100%, which, as you know, is not very useful; the battery should be stored with a charge of around ~80%. If the phone does not remain connected to the charger for a long time, and immediately after charging it turns off and begins to be used, then there is little point in charging it to 85%."
