15. Charge the smartphone whenever possible: Contrary to general opinion - this is perfectly OK, even desirable! ...That's not the case with today's lithium ion (Li-Ion) batteries... Feel free to "Top Up" today's smartphones anytime ...There will be many more charge cycles possible to our batteries if we recharge from 40% (used capacity), than from 80%. Any source on this one? Not like I have a source that disproves it but definitely counter to what I have been reading on all battery-saver advises. Thanks.
Simple Guidelines to Prolong Lithium-ion Batteries -Do not discharge Li-ion too low; charge more often. -A random or partial charge is fine. Li-ion does not need a full charge.
