Theoretically, Li-Ion or Li-Po batteries should ensure a permanent working period. However, the charging cycles, the temperature on which these devices are being exposed and the environments in which they are placed, could significantly reduce the energy storage capacity of the batteries. The next advises would help you extend the battery life of your device.
Recharging cycles.
it is always a good idea to never let your battery to drain completely. Once it is drained completely it could appear the risk that the battery to not be able to start the loading process again. The bigger risk is with Li-Po batteries, as described above. Therefore we advise you to recharge your battery when the energy level goes below 20-30%.
Another thing you should is that it doesn’t matter if the battery is fully recharged. You can unplug the recharger even if the level of energy is lower than 100%.
A charging and de-charging process is called cycle. The producer of a battery specifies that this has a life of 300 to 500 cycles. In reality, the the number of these cycles is much higher when you are charging your laptop battery more frequently. The below mentioned table would give a good ideea:

In the last period of times, the battery producers are measuring the life of these devices in years, but this not a very accurate term.
Storage and Temperature.
the number of cycles is not the only factor which decides the life of your battery. Anther very important issue is the environment and the temperature in which the batteries are being kept.
Therefor, if you are not going to use the smartphone for a long period of time or you plan to use the laptop at home without its battery for a long period of time, then you should load its battery to 40% of its capacity, and to store it at a temperature of maximum 25 degrees Celsius. It can even be stored in the fridge, at a temperature of 2-4 degrees but not in various environments where the temperature goes below 0.
Caution: if you plan to use the laptop at home, plugged in to the power network, then you should know that, if you keep the battery inserted, this one will stay permanently loaded at 100% and at high temperatures, too.
What to expect in the future?
Despite the fact that it does not show, the Li-Ion technology is currently developing and the performance of these kind of batteries are currently growing with 6% each year. However this process is too slow and cannot keep the pace with the fast hardware performance growth.
The things are slowly being improved. At the end of the last year, a researchers team from Lawrence Berkeley National Laboratory (California) has created a polymer device which is able to store 8 times more energy, improving in this way the battery life.
In the same time another team of researchers from Northwestern University have managed to increase by 10 times the storage capacity of a li-Ion capacity. This was accomplished after discovering a way through which the number and the mobility of the ions can be increased.
Bill Gates has also invested in Liquid Metal Battery which is currently developing a battery which is based on liquid metals.
Therefore, even if for a period of time we will have to use the same old Li-Ion and Li-Po batteries, the futures still sounds good.
Conclusions.
The way of using and storing a battery can have a major influence on its life. However, the rules of keeping these device are very simple and can be very easy accomplished.
