Battery Capacity Scissors

Battery Capacity Scissors, One of the features of premium terminals that became popular in mid-range devices in recent years is, without a doubt, fast charging.

Fast-charge mobiles have batteries with 10% less capacity than slow-charge terminals.

The fast charge, present on the vast majority of mid-range and high-end mobile phones on the market, is really useful since it allows you to fully charge the smartphone in less than an hour but this feature to has a B side: fast charging terminals reduce the capacity of your batteries.

Cell phones with fast charging see their battery capacity reduced

Battery Capacity Scissors, Faster Charging, Less Battery Capacity

Recently, the guys from GSMArena released a report that assesses how battery capacity loses android terminals with fast charging compared to devices that do not have it.

These are the 10 fastest-charging cell phones on the market right nowIn this sense, the results of this research, in which two dozen terminals were analyzed, reveal that mobile phones with fast charging see their battery capacity reduced, on average, by 10% compared to slow-charging smartphones.

Therefore, if a smartphone without fast charging has a 5000 mAh battery, a similar fast-charging model will drop its battery to 4,500mAh.

So, for example, the Xiaomi Mi 10 5G is equipped with a 4,780mAh battery with 30W fast charging that completes a full charge cycle in one hour and 12 minutes and the Xiaomi Mi 10 Pro 5G has a 4,500mAh battery with 50W fast charging that fully charges in 50 minutes.

In this case, we see that the battery capacity difference between the two is only 280mAhwhich represents a reduction in its capacity of 6% and that charging time is only reduced by 20 minutes.

These are the results of the analysis done by the guys from GSMArena

This report also reveals that mobiles with fast charging speeds between 18 and 33W don’t see their battery capacity reduced compared to standard charge models and so it is from 50W charging speed where we are already starting to see smartphone batteries losing capacity.

A good example that terminals with a fast charge of less than 50W do not see their battery capacity reduced is in comparing the Xiaomi Redmi Note 9 Pro released in India and the global Redmi Note 9 Pro since both have a 5,020 mAh battery, despite the fact that the first has 18W fast charging and the second has 30W fast charging.

Best cell phones with 5,000 mAh battery or more, forget the chargerOnce you know the advantages and disadvantages of fast charging, before buying a new smartphone, you will have to decide if you prefer to have a device with a smaller battery that charges in an hour or less or a terminal with a larger capacity battery, but with slower charging.
