The smartphones that are using now come with two types of batteries. One is Lithium-ion battery and another is lithium-polymer battery.Due to the user’s lack of knowledge about them the lifespan slowly decreases. So, this is 5 tips to make your battery last longer.Don’t discharge your battery fully: Lithium batteries degrade faster when you perform a full discharge from 100% to below 20%.These batteries aren’t prominent for that kind of usage. So, always perform shallow discharges. Starting from 100% discharge it to maximum 40% and then charge again.Don’t leave it after full charge: This is another mistake that most of people do. Most of the people leave their phone at charging and then forget about it and many also charge it overnight.This causes damage to battery due to charge dissipation which in turn causes the generation of heat So, either keep track of phone while charging or if someone is going to charge it overnight make sure to use some kind of smart charger which would stop charging the device after it’s full.This will enhance the battery lifespan.Heat is the biggest enemy: Heat is indeed the biggest enemy of any smartphone battery. Heating will cause smartphone battery to degrade faster.So, someone plays a lot of games or pushes the phones to it’s limit it should know that the phone’s battery is getting degraded day after day.Discharge it fully once a month: Manufacturers prefer discharging battery once a month fully. The reason is the batteries that are used in phones are smart batteries which are able to show what percentage of battery still remains.So, according to the manufacturers due to so many shallow discharges this feature starts estimating wrong. So, it`s better to discharge them fully once a month to start things fresh.Use the supplied Charger: Many people use different kinds of charger to charge their phones. Even sometimes people are using fast chargers to charge a phone that doesn’t even support fast charging.The internal circuitry provided in the phones for charging the device can only work with sufficient amount of current and voltage ratings.So, if current with higher ratings are applied to those circuits then there’re chances of it getting damaged. SO always use the supplied charger only to charge the phone.And if for some reasons your supplied charger is damaged then use a charger with the same rating of the supplied charger from a reputed brand.If anyone does all these things as much as possible then a battery may easily last more than 3-4 years.
