Default Battery life on 7.0.0.585

Please Login to Remove!

Although it doesn't look to be posted here, the official 7.0.0.585 was released.

I installed it on Friday... here's a summary of my battery life through some fairly low use this weekend. I would say the emphasis here is how well it saves power while on but not really being used.

This was done with Cellular, Wi-Fi, Bluetooth and NFC all on. Wi-Fi was connected, bluetooth and NFC were on but never used.

Friday:

11:42pm - full battery

Saturday:

11:00am - 80% (received 2 bbm's and 1 text)
1:20pm - 75% (receive 1 bbm)
5:09pm - 75% (sent/received 6 bbm's)

Sunday:

12:26am - 60% (quick phone call and a few texts)
1:03am - 60% (receive email and open weather app)
3:23am - 55% (no activity since 1am)
12:32pm - 40% (received facebook notification, checked and refreshed)
11:30pm - 15% (couple of bbm's and texts)

Monday:
8:10am - 3% (time to charge!)

Just a note, you should never let a lithium battery get below 20% on a regular basis. Doing so can damage the battery and seriously reduce the cycle time and also require replacement much sooner than normal.

Maybe you were just testing, but a lithium battery works much better and lasts longer if you keep it topped up when you can.

Yeah this was more for a full test of how long it can go on this OS. If I do some further testing, I'll see the time it takes to go form 100 down to 30 or 20%

Kind of silly there's this 'rule' for optimal battery life, but it does hold true
