The poor insulation of the transformer can be confirmed if the data (USB/RS-232) port has obvious isolating components, like optos, as it indicates that the manufacturer doesn’t rely on the main transformer isolation alone. The battery and other internals are not touchable without this hack, consequently the manufacturer may have selected a lightweight insulation. it doesn’t fulfill the requirements that are needed between line voltage and touchable parts. In many European countries (with reversible Schuko plug), it means the battery may be connected directly to 230 V live voltage or to the 0 V neutral, depending on which way you plug it in the wall outlet.Įven if the UPS has an isolating transformer, the isolation is probably functional only i.e. Google's New Nexus Devices & Android 5.Indeed! I have seen UPSes where the battery is directly connected to one of the AC lines.

Knowing that charging to a full 100% isn't the best practice for long-term battery health, developer harsha1397 created a root app that lets you choose your own charging limit. This is not even getting into the whole Note7 exploding battery fiasco - which, by the way, Samsung once tried to remedy by issuing an update that limited the phone's battery to 60 percent. To be more specific, ResearchGate found that charging a battery to only 85% yielded a longer lifespan than charging to the full 100%. In a cruel twist of fate, the act of charging your phone's battery causes it to heat up, and topping it off to 100% charge contributes to reduced capacity over time. Lithium ion batteries (the type used in most modern electronics) start to lose their ability to hold a charge over time, and the two biggest factors that contribute to this are excess heat and overcharging. There's a lot of conflicting information out there when it comes to the best habits for charging a smartphone's battery, so let's clear some of that up right off the bat.
