r/iPhone6S on Reddit: If battery health is bellow 70% its time to replace battery
July 3, 2019 -
If your iPhone 6s battery is bellow 70% battery health then it is time to replace it.
You can buy the battery online and replace it yourself or you can pay apple to do it for you.
Too check battery capacity you go to settings then go to battery and then battery health and you will see your battery capacity
To replace the battery you will need a suction cup, pry tool and the Philippe screwdriver and a small plus screwdriver.
First you remove the two screws at the bottom of the phone then you will use the pry tool and the suction cup to lift up the screen (be careful so you don’t damage the ribbon cables) after you remove the screen remove the plate on top of the battery that contains two screws. Lift the metal bracket and remove the battery from the phone. The battery has adhesive strips that you will have to pull from the bottom to remove ( be very gentle to them because there is a chance of them breaking)
After the removal of the battery place the new one and reassemble the metal bracket with the two screws and then resemble the screen

At What Health Percentage Should I Replace My iPhone Battery? - AppleToolBox
November 25, 2022 - Once the battery health percentage drops below 80 percent, the amount of charge your battery can hold starts to diminish. However, that doesn’t mean you should rush to get a new battery. That number is just for orientation. There’s no one-size-fits-all with this. For example, an iPhone with 70 or 80 percent of battery health can still stay on for the whole day if you’re not watching videos or playing games.

September 13, 2023 -
Doesn't matter which phone you have.
I know it's normal for a phone's battery to degrade over time, but I'm on a tight budget right now and can't afford a battery replacement yet, let alone a new phone, so I'm trying to maintain my phone's battery health at least until I can replace the battery.
So how long does yours last with normal usage (social media, YouTube, occasional gaming)?

In my iphone 11 with 78% health it was enough to last whole day with my regular use (which is not that much compared to numbers some people post here, I'm averaging 2h40m SOT). When I was going out in the evening I used to charge it up a bit, just to be safe. When I was on vacation where I was using phone more intensively it definitely required top up during day.

How Long Can an iPhone Last with 75% Battery Health – Wistek
Before discussing how long an iPhone can last with 75% battery health, it’s important to understand the concept of battery health itself. Battery health is a measure of the battery’s capacity compared to when it was new. Over time, all lithium-ion batteries, including the one in your iPhone, naturally degrade, leading to reduced capacity and shorter battery life.
