A smartphone is its battery. In the end, it is the charge of energy that allows us to use our mobile phones on the go. Otherwise we should keep them always connected to power or a battery pack. Instead, today’s smartphones are getting thinner and more powerful. Above all, they are endowed with ever greater autonomy. This is possible thanks to modern battery technology: they are ai lithium ions and are used on most smartphones on the market.
Smartphones, tablets and even laptops, they use this type of battery that offers many advantages, starting from a greater density of accumulable energy: it means that the batteries can be smaller with the same charge compared to the old generations, and therefore lighter, thinner, more performing. But there’s a problem.
Over time, batteries gradually lose the ability to store energy. It is no longer the so-called memory effect of the first mobile phones (which used technologies based on nickel-cadmium or on nickel-metal-hydrate): modern batteries do not suffer from it, but are sensitive to a chemical phenomenon that causes their ability to accumulate energy to degrade as the charge cycles increase (charge from 0 to 100 and discharge from 100 to 0).
The phenomenon of deterioration in the capacity of lithium-ion batteries is further aggravated by the temperature: the hotter the batteries are while they are working (and therefore the faster the charging is, or the more power required by the processor and other components), the faster the battery capacity decreases.
So how do you prevent the battery from deteriorating and degrading? Right away, our advice, within everyone’s reach.

Limit charge and discharge
Experts advise to hold the charge of the battery between 20% and 80%, do not charge it to 100% and don’t download it to the end. It can be inconvenient, but it doesn’t have to be done all the time and many phones now have a Smart Charging system that slows down charging to preserve life. Also, better avoid leaving your phone charging overnight or at least keep it in a cool environment: the batteries are consumed less if they are recharged at a temperature between 15 and 25 degrees.
Less power
Charging your phone’s battery on the fly is nice, but it hurts – better to do it slowly. Therefore avoid high power chargers if possible and go slow, leaving the charge more intense and faster for what is really needed. On iPhone you can do this by selecting in the setting Battery e Battery status the option Optimized loading.
Turn off the services that consume continuously
From personal assistants like Siri and Google to localization systems that are used to remind us to do the shopping when we are near a store, there are numerous functions of the phone that keep it active even when it is not needed. Better would be to turn them off or limit them to the essentials by changing the settings in Privacy and Location Services per iPhone and in Safety and location, Position e Advanced for Android. As well as Bluetooth and wifi, when not needed, which would be better to keep off: for Android, you also need to go to advanced configurations and App permissions to prevent individual apps from using location services in the background.
Leave it to the phone
A habit that many people have, sometimes even compulsively, is to force the app to close when you are not using them. However that’s wrong, because the phone consumes more in the long run: the reason is that by doing so we educate him badly. The latest generation operating systems learn from our habits, thanks to artificial intelligence, when to pause or reopen apps. If we force closure, we don’t allow them to learn. If we still want a lower consumption, on Android you can choose app by app consumption (in the options Advanced, Battery e Restrictions in the background) while for iPhone you have to go to General, Refresh apps in the background and here, too, choose apps by app (you can also block all of them).
Take advantage of the dark side
The screen of more modern and expensive phones uses OLED technology, which has one advantage: it turns off the pixel lighting when it needs to show black. For this, the owners of iPhone from Xs onwards and those that have i Galaxy most recent oi Pixel Google (for other brands, check the technology used) can simply use Dark Mode. According to Google, its phones consume 63% less energy this way, while analysts say iPhones increase battery life by 30%. In dark mode, the white on the screen turns black and the overall consumption drops.

Other little tips
Let the phone choose the brightness level with the automatic mode. Decrease the number of notifications allowed, the interval at which mail is downloaded. Use the phone as little as possible at very low (below zero) and high (above 35 degrees) temperatures: the battery degrades very quickly. Finally, get into the habit of locking the screen (i.e. turning it off) when you’re not using your phone, either with the feature Screen and brightness, setting the automatic lock at 30 seconds, both manually. The screen is among the components that consume the most and the less you keep it on, the longer the battery will last.
These are the keys to reduce battery consumption and make it last longer. And maybe, even after a couple of years, to have a battery still in full efficiency with a capacity just under 100%.
