how to optimize battery life?

plotting_homelab@lemmy.world to Android@lemmy.world – 29 points –

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.

Waterproofing isn't some alchemy. In terms of modern phones it's just using more glue.

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...
