Like most of them, I have a Li-ion battery in my smartphone. These batteries can only survive limited charging cycles, i.e. Something like 100,000 charging cycles, although according to specialist salespersons it does not matter whether a charging cycle takes a second or an hour until the battery is fully charged.
My question: when I connect the smartphone to a laptop, it is charged, of course. But what happens if I restart the computer?
The smartphone then makes the tones that it makes when you connect it to a charger (which means I lost a charging cycle even if the device was connected via USB the whole time) - but on my old Android 4 the signal tone is for "USB Master connected "identical to" charger connected ", so I do not know whether a new charging cycle has started, or whether the smartphone only noticed during the restart that the PC was briefly" gone "and then" there "again?
Is there a kind of log file that I can view through the shell on the Android and that tells me: it was a new loading cycle - or not?
The dealer is right. Start charging every time is theoretically a charging cycle. But since the charging electronics recognize the charging status, the controller recognizes the charging power according to the battery status. That battery doesn't last forever should be clear.
The batteries feel most comfortable in a range between 20% and 80% above this, the wear increases and below this also increases. The deep discharge is the worse of the two
The fact that the number of charging cycles is not entirely true. The rule of thumb is first of all that a complete charging cycle is from completely empty to completely full… And the battery will have more partial charging cycles, e.g. 60% -80% (here 5 times as many) survived.
In the range of 20% -80% there are a few more, as far as I know, in the range 90% -100% the battery is stressed more and there are not 10 times as many.
But the battery doesn't count… Just connecting or interrupting it doesn't matter much.
