Best battery day ever on L920 - with BT on

[realwarder]

OK, so probably a complete random day of fluky battery life... but today I am half way through the second day on my L920 with 1.5 days runtime with half a day remaining... what's different? I have Bluetooth on for once.

Typically have this off as I don't use it but I got a Bluetooth speaker system to play with.

The fact that RT recently had a BT battery drain bug made me wonder if WP8 has a similar bug... that if BT is off that perhaps battery life is worse.

Likely just joining dots that don't exist (logically or otherwise), but thought I'd throw it out in case someone who typically disables BT wants to turn it on and sees if they get longer life with it on. It's the opposite of power saving measures we'd expect, but there you go!

do you sometimes leave the 920 on top of the speaker system? ... does the "battery charging" icon appaears :winktongue: .... well, I have noticed more decent battery times recently by slightly adjusting my usage style... but I am downloading Minion Rush right now... so I do not expect long battery life in the next few days! :excited:

lol, that would be really funny if his speaker has wireless charging hahahaha. What I noticed is, nothing effects the battery. Turn everything on or off, slight difference.

I notice that when I'm not using the phone, the battery is almost still, which got me to the conclusion. Its either the CPU or the screen, which we can't actually do anything about.
My 720 lasted a day, easily. So my bet is on the CPU, which also gets reallly hot.

Edit: my brother Lumia 625 lasts 2 days easily.
