ELI5: Why shouldn''t we let our smartphones go to 0% battery

So long you don''t abuse the battery (avoid letting it go down to zero, avoid extreme heat), it should last a good while. But everything has a finite lifetime, so either get yourself a phone with a replaceable battery, or plan to get a new phone after a few years. Sealed phones can have their battery replaced, but it costs a good deal more. So weigh that accordingly. Reply reply

Mastering Battery Charging: How to Interpret Battery Charger

Charging Current Changes: As the battery charges, its voltage increases, which can lower the current flowing into it. Battery Condition: If a battery is older or has issues, it might show wider fluctuations in the amp reading. To better interpret these readings, look for a pattern. A steady decrease indicates that the battery is nearing a full charge. If the reading suddenly
