The mobile phone with the best battery always has many nuances. Let's go with the most basic theory. For starters, smartphones with larger screens have to illuminate more surface area, thus requiring more power. So far, everyone agrees. Next, models with higher resolutions have more pixels, which... you guessed it... requires additional processing power and uses more battery power. The same goes for phones with higher refresh rates, so having a 120Hz screen means it will refresh twice as often as the standard 60Hz screen. shorter battery life. If you are looking for a mobile with a large screen and a high refresh rate, you will have to give up autonomy, at least in Android models. There are nuances, of course.

How to choose the mobile with greater autonomy? The size of the battery, obviously, influences, but it is not decisive. On paper, logic says that the more mAh a mobile phone has, the longer it can last between charges. mAh is an abbreviation for milliamp hours and refers to the amount of charge a mobile phone battery can store. This can be used to estimate the number of hours of battery life, although in practice this will vary depending on how you use your phone. Although, now comes the nuance, hardware and software also influence. Apple iPhones have batteries with less capacity than Androids and, however, with less capacity they have, at the same performance, practically the same autonomy.

This is seen, above all, in the most powerful mobiles of each operating system of the big brands. The Galaxy S21 Ultra, for example, with a 5,000 mAh battery, and the iPhone 12 Pro Max, with a 3,678 mAh battery, both last about 11 hours. It is true that the Galaxy S21 Ultra lasts a little longer in some tests, but it does not exceed half an hour of difference. up to 11 hours and 25 minutes in our battery test.

Then you also have to be aware that there is a balance between performance, autonomy and price. If you want many features, you have to give up autonomy. But you can also compensate for that autonomy with a fast charge. One of the best launches of 2021, the realme GT, does not stand out in autonomy, but it has a fast charge that compensates for autonomy. However, we imagine that if you are looking for a better battery it is because what worries you most is autonomy, so we have looked for the best options taking into account autonomy first and that the mobile has a balance between quality and price because in addition to a good battery you will want something no more?
