Imho what's much more important, is to charge with a low current. Do not use the supplied charger that comes with your phone. Do not use any kind of fast charger. Instead, use a simple (USB-A) wallcharger that can only supply a fixed 5 Volt. In my case, I connect my phone to my desktop pc (USB-A port!) for charging. With Android you'll usually see a message that it's charging slowly. If that is the case, you'r fine. I noticed that most desktop pc's supply the 5 Volt on their USB ports also when switched off. So, I can charge my phone overnight by using my desktop pc as well. Do not use a USB-C of your pc port because they can supply more power. This way my old google Nexus 6p (Huawei) lasted 5 years without replacing the battery. |

With smartphone smart chargers, they slow down charging as the battery approaches full. Although if you are charging overnight and charging time isn't important, it's not going to harm the battery if you charge it slowly. |

But most phones don't have such a mode (do any?). The absence of such a mode suggests you are worrying too much about it. --- End quote --- Some phones do, but it's pretty rare. I guess they would rather sell you a new phone than make your current one last longer. :-- At one point I heard a new version of android was going to have that feature, but I didn't hear any more after that. You could totally build a DIY system to do it. Use an ESP8266 mains relay module and a quick and dirty android app to turn the relay on or off depending on current battery level. --- End quote --- There's an app that will do it if the hardware is capable of it. https://f-droid.org/en/packages/mattecarra.accapp/ |

--- Quote from: PerranOak on February 23, 2022, 07:43:20 pm ---Thanks all. I did turn it right off (boot screen). The basic point is that I’m trying to delay the time until battery replacement. --- End quote --- false economy... frequently touching (esp pressing it hard for few seconds) the side on/off button will wear it out quickly. when that button is screwed, your smartphone is screwed, however pristine your battery is.. my samsung phone never turned off, unless some apps make it hanged. its been on charger at night or home and removed only when i go out or pick up/make call/text, its charge and forget thing for 5-7 years now. i tend to replace to new smartphone earlier than to replace the battery. even if i do, its quite hard to find battery replacement that performs as it was when i bought the phone new, i guess they are all bunch of unsold battery spares manufactured 5-7 years back when i bought the phone, and diminishing performance while in stores. ymmv. |

As a side note, I remember the uproar when phone manufacturers started making batteries non-removable. I think it largely started with the Apple iPhone and most other manufacturers have since followed suit. I was guilty of dismissing the idea as "stupid" and even went as far as entertaining the idea that it was somehow driven by planned obsolescence. Thinking back over all the phone's I've owned, I can't think of a single time I actually bought a replacement battery for a phone because it had "warn out" and typically I would charge them every single night (even my Nokia's that lasted several days). Even to this day I still have most of my old phones, going right back to my Nokia 5110. The battery still lasts a few days (last time I tested it in 2017 before the 2G network was shutdown in Australia). |
