So I recently bought a new honor magic 5 pro. My last phone the Huawei p20 pro was around 5 years old and started to show significantly less battery life. So I want to use this phone again for 5 years. But now I wonder should I keep the battery around 50% (65-35) and charge twice as often or should I 80-20 and charge once every two days? Is there any science that proves one is better than the other? Thank you for your information and sources.
Most important thing in my experience is getting the most slow ass charging adapter with the crappiest cable and use that for charging overnight. Many phones already have some intelligent charging strategy, but you should limit the charging speed (and thus temperature) as much as possible. My OnePlus already only charges to 80% and only finishes to 100% one hour before I wake up, helps as well. Stay away from 0% or 100% whenever possible.
