What's In A Smartphone Battery?


I have reveled a lot about high tech specs in most smartphones and why one would be proud to own a super core processor smartphone with high graphics  screen  supported with hardware based  software to tick up your day, bringing so much pleasure to a smartphone.


While we all look at the specification as the bloodline that make the smartphone tick, it all comes to a naught when we remove a good battery from the matrix, which in any case is the heart beat of the system.


Gtel has come out with national headlines after they launched   the GtelX 3  a smartphone with a very powerful battery that lasts safely over three days, defying most smartphones  limits.


The Gtel X3 Battery lasts over three days with a  key attraction of its 6,020mAh battery which they have touted to charge other cellphones making it the mother of all cellphones, devices thanks to reverse charge feature.

While we have many smartphones that are in the Zimbabwean local market,   today it would be notable that not all good smartphones batteries are ranging 6,020mAh really all about




Most people also get worried about how long their smartphone is going to last before it loses its juice, while the need to recharge and top up power always comes begging .


In the past, mobile devices used a type of battery that required you to drain them completely and charge them to full, in order to maintain their standard capacity. This is called the “memory” effect and for a long time it was common knowledge in the tech world. However, according to Green Batters this was only relevant to NiMH and NiCD batteries.

Today, we actually use Lithium-Ion rechargeable batteries which do not need to be charged or depleted fully. In fact, most Li-ion batteries perform better if you don’t drain them. Don’t worry, though, running them down to empty or recharging them early has no effect on the battery’s lifespan or total capacity.

In other words, this is not something you need to be concerned about. If your device needs a little juice then charge it, by all means.

Now, it’s important to note that the number of charge cycles does have everything to do with the life of your device’s battery.

A charge cycle is when a battery is completely depleted and then recharged all the way. Li-ion batteries — or most rechargeable batteries really — will degrade after a certain number of charge cycles: Popular Mechanics estimates this to be in the range of 500 to 1,500 charge cycles. That’s why it’s a good idea to do the opposite, and keep your battery full more often even if it means charging from about 30-50%.



Depending on the design and chemistry of your lithium cell, you may see them sold under different nominal “voltages”. For example, almost all lithium polymer batteries are 3.7V or 4.2V batteries.


What this means is that the maximum voltage of the cell is 4.2v and that the “nominal” (average) voltage is 3.7V. As the battery is used, the voltage will drop lower and lower until the minimum which is around 3.0V. You should see the number 3.7V written on the battery itself somewhere.


Different chargers are going to charge your Android device at different rates, and some broken chargers might not be charging your device as quickly as they claim they can.

If you’ve ever run into issues charging your device, or you’d just like to test out how effective your charger is, using simple android apps likes Ampere.

The total capacity your battery has is stored as amperage, the bigger you have the more juice one has to last the day and this is an important aspect to consider.


An ampere-hour or amp-hour (SI symbol A·h or A h; also denoted Ah) is a unit of electric charge over time, equal to the charge transferred by a steady current of one ampere flowing for one hour, or 3600 coulombs.
