With time, smartphone battery technology has also improved and now batteries with much higher capacity are available than before. After the introduction of silicon-carbon technology, now Chinese companies have started providing batteries with capacity up to 7,000mAH in their smartphones. However, high battery capacity does not mean that its backup will also be long. Many other things of the phone also matter for long battery backup.
Capacity is just the beginning
A higher mAh battery means it can store more charge, but it does not guarantee a longer backup. Even a 5,000mAh battery can give longer backup than a 7,000mAh battery in many cases. It depends on many things including the phone screen, demand of apps and software optimization.
Displays with higher refresh rates require more power.
Nowadays, smartphone displays have started coming with refresh rates up to 120Hz, 144Hz and 165Hz, which consume more power. Apart from this, screen resolution also affects the battery. Phones with QHD+ displays require more energy than Full HD+ panels. Apart from this, high peak brightness is also an enemy of the battery. It gives good visibility outdoors, but consumes more battery.
Processor also makes a difference
The processor installed inside the phone also has a great impact on the battery life. In view of this, nowadays Snapdragon 8 Elite Gen 5 and MediaTek Dimension 9500 chipsets are being provided, which are energy efficient. Apart from this, the thermal design of the phone is also a factor in deciding the battery life. Good thermal design dissipates heat quickly, which does not put much load on the battery.
software
Apart from all these factors, software optimization also affects battery life. Be it the iPhone 17 Pro models or Samsung’s flagship Galaxy S26 Ultra, they don’t have the biggest batteries, but they provide longer backup than phones that come with larger capacity batteries.
