Why do phone batteries have a short life and low capacity?

Every year we see smartphone companies with a wide range of capabilities. But in day-to-day usage, it is much harder to keep the battery for a day. If you go on a trip, you will be in trouble for there is no way to charge. Why are these phone batteries have a short life and low capacity? Let’s jump into the matter.

Increased power requirements compared to capabilities

One of the main reasons for battery draining is the increased number of facilities available in modern phones. For example, if you look at the Samsung Note series, there is no significant increase in the battery capacity used, even though the phone’s features are increasing rapidly.

In 2012 Samsung launched its Galaxy Note II with a 3100mAh battery. Depending on the nature of the use, it could be used for about a day at a single charge. The Galaxy Note 9 has a 4000mAh battery. Even though there is an increase of 900mAh in number, it is not good enough in terms of features that have been increased in the last six years.

The Galaxy Note II had an AMOLED display, but the Note 9 has an AMOLED display that is larger in size, brighter and has a higher resolution. It also has a faster processor, more capable graphics performance, and more RAM. The larger the screen size, the more battery power you will need.

In addition, more apps than ever before have added to our daily use. They are running in the background. As soon as a photo is taken, the Google Photos app does not just come on the screen, but it is being uploaded because it is running in the background. This process costs battery power. For mobile data (3G or LTE) and relatively low for Wi-Fi, Bluetooth and NFC use battery power throughout the day. If you are using a Bluetooth headset, watch, or a smart band, Bluetooth is always active.

As a solution, manufacturers control battery usage through software. It is done by reducing the brightness as well as the screen resolution. However, the more features the phone has, the more battery power it needs.

Decreasing the thickness of the accessories

Over time, the thickness of the phones has been decreasing. The first iPhone released in 2007 was 0.46 inches thick. In late 2017, the iPhone X went to the gym, losing 40% of its stomach and gaining 0.30 inches.

With the thinning of modern phones, their sleek appearance, ease of use, and ease of pocketing in pants such as denim, on the other hand, diminish the accessibility of the phone’s internal components. Most of the compensation is the small size of the battery. Battery technology has improved to the same capacity in a smaller space, but the small size does not give rise to a mAh increase in the mAh value.
