The latest smartphones are mobile computers with many features and apps. A strong battery, as delivered with every new phone, will enable your smartphone to function optimally. When the battery begins to weaken, your mobile phone function will be less than ideal but on the whole it will be satisfactory. You will need to charge the battery sooner and find that the battery will not hold the charge for a day's worth of usage. And then when the battery is on its last leg you will be annoyed with poor performance and the need to recharge at the most inopportune time. This happens so much that you find yourself planning how to keep your battery charged because of upcoming events - business meetings, weekend travel, need to communicate with family, phone tag with important clients, doctors or friends. GOSH - that's frustrating!
