How to extend the lifespan of your phone battery.

           

                It’s harder to replace your phone’s lithium ion battery than it is to treat it right in the first place. Many smartphones don’t provide easy user access to their batteries. That includes all iPhones and many flagship Android phones from brands such as Samsung. Official battery replacements can be expensive or inconvenient There are also environmental concerns. Smartphones are, frankly, an environmental disaster and extending the lifespan of your phone battery helps mitigate that. Here are some things you can do to preserve and extend the lifespan of your phone battery.

display black it doesn’t block the backlight with a pixel like some iPhones and many other types of screens. Instead, it doesn’t display anything at all. The pixels displaying black just don’t turn on. This makes the contrast between black and colour very sharp and beautiful. It also means that displaying black on the screen uses no energy, and darker colours use less energy than bright colours like white. Choosing a dark theme for your phone, if it has an OLED or AMOLED screen, can save energy. Some people find a darker theme is easier on the eyes in terms of preventing eye strain, and less light overall may mean less blue light, which can affect sleep patterns.

With every charge cycle your phone battery degrades slightly. A charge cycle is a full discharge and charge of the battery, from 0% to 100%. Partial charges count as a fraction of a cycle. Charging your phone from 50% to 100%, for example, would be half a charge cycle. Do that twice and it’s a full charge cycle. Some phone owners go through more than a full charge cycle a day, others go through less. It depends on how much you use your phone and what you do with it.

If you can slow down those charge cycles — if you can extend the everyday battery life of your phone — you can extend its battery lifespan also. Basically, the less you drain and charge the battery, the longer the battery will last. The problem is, you bought your phone to use it. You have to balance saving battery life and lifespan with utility, using your phone how and when you want it.

Avoid extremes of heat and cold. If your phone gets very hot or cold it can strain the battery and shorten its lifespan. Leaving it in your car would probably be the worst culprit, if it’s hot and sunny outside or below freezing in winter.

Avoid fast charging. Charging your phone quickly stresses the battery. Unless you really need it, avoid using fast charging.

In fact, the slower you charge your battery the better, so if you don’t mind slow charging overnight, go for it. Charging your phone from your computer as well as certain smart plugs can limit the voltage going into your phone, slowing its charge rate. Some external battery packs might slow the speed of charging, but I’m not sure about that.

Avoid draining your phone battery all the way to 0% or charging it all the way to 100%.Older types of rechargeable batteries had ‘battery memory’. If you didn’t charge them to full and discharge them to zero battery they ‘remembered’ and reduced their useful range. It was better for their lifespan if you always drained and charged the battery completely.

Newer phone batteries work in a different way. It stresses the battery to drain it completely or charge it completely. Phone batteries are happiest if you keep them above 20% capacity and below 90%. To be extremely precise, they’re happiest around 50% capacity

 The healthiest charge for a lithium ion battery seems to be about 50%. If you are going to store your phone for an extended period, charge it to 50% before turning it off and storing it. This is easier on the battery than charging it to 100% or letting it drain to 0% before storage.

A smartphone’s screen is the component that typically uses the most battery. Turning down the screen brightness will save energy. Using Auto Brightness probably saves battery for most people by automatically reducing screen brightness when there’s less light, although it does involve more work for the light sensor.

The thing that would truly save the most battery in this area would be to manage it manually and fairly obsessively. That is, manually set it to the lowest visible level every time there’s a change in ambient lighting levels.

If you leave your screen on without using it, it will automatically turn off after a period of time, usually one or two minutes. You can save energy by reducing the Screen Timeout time By default You may be fine with 1 minute, or even 30 seconds. On the other hand, if you reduce auto-lock or screen timeout you may find your screen dimming too soon when you’re in the middle of reading a news story or recipe, so that’s a call you’ll need to make.
