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.
I wish it was as easy as just buy $50 battery. But with a waterproof phone I don’t think waterproofing will be ip68 when I replace the battery and being able to just dunk my phone in water or run it under the sink when it’s Dirty is so freaking easy. I do find it kinda weird that you doing 80-20 made the battery worse I think it might be just newer battery tech/software but you saying that your new phone also has the battery degrade faster than your previous phone makes me wonder if maybe manufacturers are already doing 80-20 in the software maybe and mapping 80 to 100 and 20 to 0. And that charging it more often is worse than just doing 100% and charging it less. I think I am definitely going to need to setup some experiment to figure it out. And maybe going to ask honor for advice. Thank you for sharing this information.
I would take the parent poster’s experience as definitely anecdotal/coincidental. A lot of factors can cause a battery to degrade faster, beyond just faster charging or doing full charge cycles. For instance, simply using the wrong kind of case (say, something like a heavy-duty Otterbox case) could cause heat to build up and reduce battery health. It could even be caused by a cheap or non-compliant USB cable..
If you want some real battery facts, check out the Battery University, it should have all the info you’re after.
Exactly, that’s what I was getting at. Personally, I’ve concluded that there are too many factors outside of my control to warrant worrying about it too much.
@plotting_homelab@lemmy.world fair enough. I’ve never made use of the waterproofing features on any phone I’ve owned. I think my previous ones didn’t even have any to being with…
https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries has a table explaining exactly what I wanted to know 10% discharge depth results in a larger total charge the battery can carry throughout its live than a 80% for example
