Don’t charge to 100 percent
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.
What percent should you charge your phone?
Do maintain your battery charge level between 40 percent and 80 percent. The ideal charge level for a stable battery is in the upper mid-range. Keeping a battery between 40 percent and 80 percent charged as often as possible will help you get the most out of its lifespan.
Should you charge your phone to 100?
According to Battery University, leaving your phone plugged in when it’s fully charged, like you might overnight, is bad for the battery in the long run. Once your smartphone has reached 100 percent charge, it gets ‘trickle charges’ to keep it at 100 percent while plugged in.
At what percentage should you charge your iPhone?
Apple recommends, as do many others, that you try to keep an iPhone battery between 40 and 80 percent charged. Topping up to 100 percent isn’t optimal, although it won’t necessarily damage your battery, but letting it regularly run down to 0 percent can prematurely lead to a battery’s demise.
Is it bad to charge your phone at 80?
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.
