runningaround

Should I always let my mobile phone battery fully discharge?

Sometimes it's just got a little bit of juice left but I want it charged to go out somewhere...

It's not necessary to let your battery fully discharge every time you use it. On the contrary, lithium ion batteries prefer a partial discharge. There's an incredibly interesting article about lithium ion batteries here, on Battery University: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

That article is a bit mis leading. Allowing your phone to discharge by 10% means you are only using it for 10% of the battery lifetime, so for 600hr standby battery, only using it for 60h before recharging. I've been a geek and modelled this. If you sum up to total hours used on a 10% DoD it actually accumulates to less than the 100% DoD. Yes you recharge more, but have to recharge more frequently. Using the data in the table, 50% DoD actually gives you the best total hours before the battery gets to 70% point they talk about
