There are two simple ways you can preserve battery life — no matter how you use your device: adjust your screen brightness and use Wi‑Fi. Dim the screen or turn on Auto-Brightness to extend battery life. To dim, open Control Centre and drag the Brightness slider to the bottom.
Avoid situations where your phone can overheat, especially when your battery is fully charged. Your battery drains much faster when it's hot, even when not in use. This kind of drain can damage your battery. You don't need to teach your phone the battery's capacity by going from full charge to zero, or zero to full.
Go to Settings > Battery. Information about your battery usage and activity appears for the last 24 hours and up to the last 10 days. Insights and suggestions: You might see insights about conditions or usage patterns that cause iPhone to consume energy.
No matter what you do, your iPhone® battery has a limited shelf life. As it ages, the battery slows—so a full charge won't last as long. Most batteries are good for at least 2 to 3 years, often longer, but how do you know when to replace your iPhone battery? At Asurion, we help millions of people maximize their tech.
It's especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity. That is, your battery won't power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further.
When kept at 100% charge your battery not only experiences higher stress from the higher voltage, heat also builds up over time. While mobile phone batteries wont overheat to the point that it's dangerous to the user, exposing a battery to high heat is one of the fastest ways to shorten its lifespan.
When your battery is slow, turn on your phone's low-power or battery-saving mode. Both Androids and iPhones have special battery-conservation modes that turn off background apps, decrease processing power, dim the screen, and disable other services that can drain your battery quickly.

It's best to charge it when it goes below 20%, primarily to avoid the risk of it going to zero when you don't have a charger available, and to prevent unexpected shutdowns when you might need the phone.
Shomes recommends charging your iPhone as it needs it. If you go to sleep and it has a 40 or 50 percent charge, leave it. Then charge it some time during the next day when it gets into the red. That way, the battery won't be stressed, and its health will last way longer than it will when overnight charging.
Is it bad to charge my phone to 100 percent? For optimized battery life, your phone should never go below 20 percent or never above 80 percent. It may put your mind at ease when your smartphone's battery reads 100 percent charge, but it's actually not ideal for the battery.
The most fruitful battery life gains were found when switching from light mode at full brightness to dark mode. In the Purdue study (via Android Authority), researchers looked at dark mode power usage from six different applications.
Overcharging or continuously charging can: Cause corrosion of the positive battery plates. Increase battery water consumption. Increase the internal temperatures, which can lead to heat damage that is beyond repair.
If your phone's battery is draining faster than usual, it either means you're using a lot of energy or your phone is not using energy efficiently. This could mean you're overworking your phone by running too many applications, or something is physically wrong with the phone battery itself.
Yes, you can use your smartphone while charging. There is no danger in using your phone while it's charging. When you use your phone while charging, the battery is charging at a slower rate than normal to allow enough power for the ongoing usage.
To put it simply, there's no danger in using your phone while it's charging. It's completely safe to use your phone from a wall outlet or portable charger and does not send electrical waves through your body.
Apple says that an iPhone battery “is designed to retain up to 80 percent of its original capacity at 500 complete charge cycles when operating under normal conditions,” but regular overnight charging accelerates that degradation.
When should I replace my iPhone battery? Typically, when your iPhone holds less than 80% of its maximum capacity, it's time to upgrade the battery. You can check your battery's health by going to Settings then Battery Health.
This will reduce battery stability in the long term. SImply avoid charging overnight and instead charge your phone twice a day, once in the morning and once in the evening.
As a good practice, you should avoid charging your iPhone to 100% all the time and not let it go below 25%. Ideally, keep the battery percent somewhere between 30% and 80% to maintain your iPhone's battery health.
In actual fact, it's perfectly acceptable to charge your phone three times a day- unless you constantly keep the battery levels near 0% or 100%. Charging your phone three times a day (or even more!) is only safe for your phone's overall battery health if you do not charge it to full capacity each time.
iPhone battery durability
For most users, this represents approximately two years of use, which is why most people believe that the lifespan of a phone is two years. However when it comes to iPhones, you can expect between three to five years (maybe more) with proper care.
