How can I take the best care of my phone’s battery?

This is a question that most of us here at Consulting on Wireless hear almost daily. Several of us have differing opinions on what you, as the user, should be doing. Does leaving you phone plugged in all night hurt your battery? Does letting it die hurt your battery? What about apps that drain my battery heavily? What about those “Battery Saver” apps? All valid questions, and they will be covered in today’s post.
So, first question: Does leaving my phone plugged in all night hurt my battery?
The short answer here is, yes.
You see, phones, and almost every other device that has a re-chargeable battery are always on devices. Which means, they are always using resources that drain your battery. Your phone, even though the screen is off, and apps are close, is STILL using battery keeping a cellular signal and searching for text messages, phone calls, social media notifications, and other things around there. So, when you phone is plugged in at 100% battery, it is still draining slightly each time it looks for something, which is constant. It may be a tiny amount, not even 1% of your 100% battery, but it is still something. So, your phone is constantly discharging and recharging while plugged in. Most phones around today have very good standby features, that only let certain applications work, such as Android’s Doze feature, or have very good management features built in, such as all iPhones. And, some phone companies claim that their chargers are intelligent and cut the electrical charge to your device when it detects that the battery is full.
Aside from that, most phones charge very quickly nowadays, and if you unplug it at 100% before you go to bed, will only drain maybe a few percent, so you can plug it in while you get ready in the morning and be ready to go.
Second question is: Does letting my phone die hurt my battery?
The short answer, again, is yes, but keep reading…
Each battery is rated for a certain amount of ‘charging cycles,’ or the amount of times the device is plugged in to charge. If you are someone who likes to upgrade their phone often, then this number really will not affect you. But, if you keep your device well over 2 years, you should be a little concerned. The average battery cycle rating for most devices is about 2 years worth of use. This is a large number, roughly 800 charging cycles. However, each time you do so, it decreases the life of your battery slightly. If you like to track your battery usage, you will not even notice it. Everyone has days where there phone is hardly touched, and everyone as days where there phone doesn’t make it past noon. But, each time you charge your phone, or let it die and charge it back up, your battery dies a little inside, no pun intended.
Third question: What about apps that drain my battery?
Certain apps are very resource heavy, such as Facebook. Aside from the fact that a lot of us stare at it all day on our phones, it also is constantly looking for updates, uses GPS for some of its features, and does all of these things on top of what you are already doing. As I said in the last question, phones are meant for about 2 years of usage, but killing your battery constantly can make that number go down a lot faster, and using apps that kill your battery, can definitely be the blame.
Finally, What about those “Battery Saving” apps?
Certain apps that you can download offer certain ‘battery saving’ tactics, such as freeing up storage space on your phone, clearing the cache and RAM, and even bringing your brightness down to super low levels. The fact here is that, these apps do NOTHING for your phone. In fact, most of them actually drain battery, and some even use your data! There are some legitimate apps, such as Doze from the Google Play Store, which lets you disable which apps use resources when your device’s screen is turned off. But this app doesn’t claim anything too crazy, just that it will prolong your battery life by blocking certain notifications and app services. Other than that, no app can save your battery, only you can.
Don’t have your brightness on full blast, don’t use resource-heavy apps all day, don’t leave your battery on the charger all night; these will help you prolong your battery. More than likely, you have figured out that some apps are worse than others. Others, may still be carrying a charging brick and cable everywhere they go!
