Battery saving exam technique

A technique for saving batteries.

Or, how exams saved batteries. Yes, that’d be it.

I just realised how long it’s been since I charged my phone. I like to think it has a decent battery life, although not as good as some, but still — it’s generally pretty good. My usual charge cycle is about 3 or 4 days, with me placing it on the charger only as it starts beeping and going into spasms saying “FEED ME!!!”. Well, not quite… you get the picture.

So when I realised that I’d last charged it on Sunday night, I was a tad suprised. The battery display meter has three segments, and it’s currently sitting on two. Phwoar. That’s Monday, Tuesday, Wednesday, Thursday, Friday — We’re on Saturday. I think I’m about to make my first week without a recharge!

As I scanned the phone, my battery meter fell to one bar… still impressive. That said, given usage patterns imposed by exams this week, perhaps I should change my phones screen display message…
