What is the best way to charge a battery for Android phones and tablets?
To best way to charge a battery like lithium-ion batteries, is not the same as the old style batteries. Lithium-ion batteries seem to be more reliable, hold the charge longer, and have less charging problems then its predecessor. The lithium-ion battery should have a lifespan of three to five years, which amounts to about 500 to 1,000 charging cycles. A battery that is three or four years old will not last as long as a new battery.
The events that will shorten the lifespan of a lithium-ion battery are temperature, age, and number of charging cycles. So what is the best way to charge phones and tablets without shortening the life of the battery?
Well, first off, all batteries will loose some life, little by little, over time. But you can mitigate the lose of life with properly battery charging methods.
- Don’t charge overnight – some chargers are smart and will automatically turn off the charging when the device’s battery reaches 100%. But, it seems that the best charging habits are to not let the battery charge to 100%. You should stop the charging at around 80% to 90%.
- Don’t let your battery charge get below 20%. If you can keep the battery charged at between 20% and 80% all the time, that is the optimal method to protect the life of the battery.
- Small short charges are better than full 100% charges. Unlike the old style batteries, the lithium-ion batteries are not negatively affected from doing a short charge. You don’t need to let the battery get fully discharged before charging again, contrary to the advice for the old style batteries.
