A few things about smartphone battery
Please read the article published earlier on this site regarding batteries and power banks.
Battery tech remains same for power bank or smartphone. Battery needs to be charged carefully after you buy a new smartphone. Please maintain a strict charging discipline. A full charge for a large screen smart phone usually lasts for only one day. To save from the trouble of a discharged cell battery, we keep the phone plugged in wherever possible. This is where the problem begins.
A charging cycle is one charge from zero to 100 % charge and discharge from 100% to zero. Even if you do not charge to 100% and stop at say 70% and then use it again means you have used up half a cycle. Number of charging cycles of each battery are fixed. If high quality components are used, the chemicals in the battery will last longer and give more charging cycles.
For the first few charging cycles, the battery has to be charged at least up to 95 % and then allow it to discharge till about 10 % before charging again. Use only the authorised charger provided with the smartphone. Do not use the phone while charging, even to check messages. Playing games while charging the phone is a severe threat to the life of the battery. In fact battery is the first thing that loses its potency with prolonged smartphone use.
