In the last few years the autonomy of our mobile phones and even gadget phones decreased rather than grew. This is not a great progress for our technology. Many mobile phones need to be recharged after just one day usage. What could be the problem? The answer is quite simple: our mobile phones have more functions these days. Every new application on our mobile phone induces greater battery consumption. Let’s turn our attention to the GPS. Every new high-end phone has one. But then again everyone likes more functions on their mobile phones and once these functions have been integrated, then is no turning back. We call it technological evolution. This days mobile phones are not just about calling or texting, but also about music or surfing the web. However all these functions withdraw energy from the accumulator of our mobile phone.

Still, the autonomy of a certain model depends on the way the phone is used. The same device can ‘survive’ only one day on an intensive usage, but also a whole week before it well need charging (on a low usage).


One of the most important reasons the autonomy period of our mobile phones is low is the accumulator power (or capacity). The power of the Li-Ion and Li-Polimer accumulators grew year by year (on a constant level). A cylindrical notebook accumulator with an 18 mm diameter and length of 65 mm could stock 1200 mAh. Nowadays this value was increased to 2600 mAh. The next five years will not bring any change in the accumulator land. Our mobile phones will still have lithium accumulators. Their big advantage, besides the bigger power storage (compared to the Nichel Cadmium), is that they don’t present the Memory effect. The Memory effect will not allow you to recharge your mobile phone until its battery is completely empty. The lithium accumulators are more expensive to produce then the Nichel Cadmium ones. Therefore is you want to buy an extra accumulator you will pay quite much. The power of the accumulator is constantly attacked by numerous consumers, like the broadcasting chip. The small CPU’s from our mobile phones use little power (it actually lowered its consumption from 5 to 1.3 volt). With every new technological progress the consumption of power decreases. The difficult moment is occurring right now. The processing frequency is around 500 MHz, but in two years they will grow to about 2 GHz. This will surely affect the chip power consumption but a better frequency is mandatory because of the high data flux.

One of the most ‘starving’ applications on our mobile phone is actually the calling function. The consumption depends on the network you use. In the GSM networks you can speak twice as much than in the UMTS network. You can save some power is you switch from the UMTS to the GSM when you don’t need video calling or high speed connectivity.


For many applications, the actual use of power is owed to the phone display. Let’s take example the browser. The application is not that big but the display is on during the entire navigation (this leads to a high use of power). The standby period with the display on is slightly lower than the calling period – because the display is not on during a call. This is one of the reasons the manufactures are preoccupied to diminish the period of time while the display is on when the phone is not used and to turn itself off while an outgoing call.

Another application that devours the power of the accumulator is the music player. It’s a little less consuming than the other but don’t let yourself fooled, it will empty your accumulator in 24 hours. If you listen to music from your mobile phone by using a Bluetooth stereo handset or Bluetooth speakers then the mobile consumes more power.

Watching movies on your mobile phone is the latest direction right now. However this application will drain your accumulator dry in a few hours (2 – 5 hours, if you are lucky).

You can use the WLAN to surf on web rather than the UMTS. The WLAN will save energy.

Be careful with the GPS. It’s very consuming because it uses simultaneously the display and the Internet connection. The autonomy of your mobile phone will decrease ( with your GPS on ) to about 2 hours.

We all want a single device that can do everything, but the reality is different than what we want. The more you use a single device for all your needs; there are more chances that it will crash and burn. So you like music and movies on the go, buy an iPod or other player, you need GPS, buy an actual GPS and not at least do buy a good phone that doesn’t need daily charge. is a gadgets review with pics, graphics, photographs, images, video recordings, something else blog with webmaster’s comment.
