Mobile phone battery life

[Dr Jekyll]

Why does it vary so much? Every weekday I charge my Samsung up overnight, take it to work, check my emails, then it usually sits on my desk untouched for hours. Sometimes it's down to 90% charge by the time I get to work and is running low by mid afternoon, other times it's still on 60% by evening. Same location, same settings, same use.

I did wonder if the base station near work was out of action sometimes so it was communicating with one further away, but on bad days the battery life is noticeably lower than usual by the time I've finished breakfast and carries on draining at a high rate all day.

Must be a Samsung thing, my S4 used to have funny moments where it would consume all it's battery for no specific reason. The Xiaomi that replaced it seems much better and I usually have at least 50% left in it at the end of the day, sometimes more.

If your phone is fast charge enabled it will worsen the battery performance over time.

The Accubattery app (free) is good for assessing your current battery capacity against when it was new.

You'll be able to tell whether the drain is because of the battery performance or due to an app running in the background.
