If you use up only 50 percent of your battery before plugging it back into a charge, you can go 1,200 to 1,500 cycles before your battery starts to go into decline.
What’s more, if have the inclination to really micromanage your battery charging, it’s better to charge nearly, but not all the way, to 100 percent.
What percent should you charge your phone?
Roughly speaking, every 0.1V decrease in cell voltage doubles the cycle life, according to Battery University. Therefore, charging up your phone in that 30 to 80 percent range keeps the voltage lower and prolongs the battery lifespan. Battery University Lower battery voltages help prolong capacity over time.
Should I charge my phone to 80%?
A good rule of thumb seems to be to never charge your phone up to more than 80 percent of capacity. Some research shows that after 80 percent, your charger must hold your battery at a constant high voltage to get to 100 percent, and this constant voltage does the most damage.
How low should I let my battery get before charging?
Recharge whenever convenient.
Don’t let it fall below 20% (or higher) and avoid fully discharging the battery unless calibration is needed. Unplug at battery level between 80% (or lower) and 100%. Don’t let your phone stay at 100% level for too long, i.e., plugging to charger after fully charged.
