1. Keep your battery from going to 0% or 100%
2. Avoid charging your battery beyond 100%
While leaving your phone to charge overnight is a common habit, it can actually shorten its battery lifespan. When kept at 100% charge your battery not only experiences higher stress from the higher voltage, heat also builds up over time.
3. Charge slowly if you can
No one will argue that fast charging technologies are a great time-saver. If you’re intent on maximising your battery’s lifespan, you should probably save them for emergencies as they can stress out and damage your battery, especially if you have an older phone.
On the other hand, charging your battery more slowly is good for it. As such, charging your phone through your computer or laptop can actually be a good thing
4. Turn off WiFi and Bluetooth if you’re not using them
It’s also important to keep in mind things that will help your battery lastlonger on a single charge. After all the fewer charge cycles your phone battery goes through, the slower it degrades and the longer its lifespan.
One common drain on battery life is leaving your phone’s WiFi or Bluetooth on while they’re not in use as they do drain your battery scanning for networks or devices to connect to.
Realistically speaking, if you’re just moving from one place with WiFi to another, like going from your home to the office, it’s probably not a big deal if you don’t disable your phones WiFi. But if you’re spending a whole day out and not planning to use your WiFi at all, you should probably turn it off to save some battery life.
5. Manage your location services
A lot of apps these days track your phone’s location to support their services, constantly scanning with a combination of GPS, WiFi, Bluetooth and cell tower locations for maximum accuracy. To ensure that you’re not wasting battery life, it’s best to only let these apps access your location services only when you’re using the app.
6. Let your assistant go
While features like Google Assistant and Siri can be really useful to have, they add to the battery drain of your phone, especially if they’re constantly listening out for your voice commands.
If you don’t need or hardly use these features, it’s best to disable them, or at least disable their “Hey Siri” or “OK Google” voice command function.
7. Don’t close your apps, manage them instead
By now you may be thinking you should start closing everything running on your phone as much as possible save battery life. Wait no, not so fast!
Closing apps i.e. force-quitting apps that are running in the background on your phone doesn’t actually improve your battery life at all. In fact, it can actually make things worse.
8. Keep that brightness down
We get it, your phone screen is gorgeous. But screen brightness is a major drain on your phone battery. If you need to conserve battery power, turning it to its lowest-but-still-readable setting is the way to go.
9. Make use of smart battery modes
Today’s Android and iOS devices come with their own smart battery saver or low power mode. These are especially helpful as they automatically cut back on functions that drain battery life, such as CPU usage, notifications, mail fetching and screen brightness.
10. Embrace the dark mode (if you have an OLED screen)
If you got a more recent phone like the Samsung Galaxy S9 or any device having OLED display could cut down on your battery drain by switching to Dark Mode.
Hope this will help some people.
