Charger control app

great, is it possible on xperia x?

On Xperia X not working, tried before posting here. It is working only on Jolla 1 and maybe aquafish.

On my old Jolla 1 I also used it a lot, howver I'm not sure how helpful that is for the battery, as your phone oscilates between upper and lower bounds all night. It would be great to have the option to charge to the upper limit, terminate charging and still drive the phone through the USB power supply, just as it is done when the battery is at 100%

schturman has no xperia, so cant fix it

... without a comprehensive description (by someone else) and analysis of what goes wrong on the Xperia X (and probably newer devices, too).

jollajo: My thought was something else - if we assume that the way from 0% to 100% is one cycle, so 10% is 1/10 of cycle. Problem is that battery has behavior like this - if it is discharged, it is quite easy to charge it to 60 or 70%, but from this point it needs more current, so battery products more heat in this range. When you connect it to the charger and then you go to sleep, battery is fully charged maybe in an hour, when it reaches 100%. The phone stops charging until percentage is below 100% (98 for example). Then starts to charge again and again battery uselessly heats up. Everyone knows that heat is destroyer of batteries. So if you set some "border" of starting charging, you can prevent this. If you set for example 85%, phone will charge to 100% and then if it is still connected to the charger, next charging will start at 85%, but I think that battery cannot discharge itself to 85% through night. So the magic is, that battery normally charges until 100%, but charger wont be pushing more juice through the rest of the night. So you maybe not saving cycles, but you are saving battery´s condition and will work for you for more time - for example instead of 2 years will work 3. And in the morning you will disconnect phone with propably 95-100% charged (I dont think that battery can discharge itself from 100% to 85% through the night)

When I was testing SFOS for the first time on Nexus 4, I bought brand new original battery and Qi wireless charger, so I got used to put it on wireless charger and not using usb for the year maybe. After a year of everyday wireless charging (when phone was quite hot after removing it from Qi charger) battery capacity went down by +- 1/3. When battery was new, it could last 3 days. A year after it could last absolutely max 2 days, more or less 1,5day practically. So it is nice example that heat slowly damages battery.
