CM 5.0.X-N1 Battery Life

I keep reading over and over the reports of poor batter life. Either I'm blessed with a bad batched phone or I'm not using something you folks are. My phone was undocked this morning around 11 AM PST and it still has 71% charge. I didn't make any calls on the N1 today.

Maybe this will help? I dunno. The phone goes in the Google Desk Dock each night. I rarely have any reason to charge it during the day. I might happen to plug it into the USB to get something off it but its not very often.

I have a min amount of apps from the Market:

iMobsters

Astro

Barcode Scanner

CM Updater

Shazam

Touiteur

Jewels

Live Wallpapers:

EarthRot

Shake Them All

NexusMod (Hmmm, haven't tried this again to see if it FC's since test1)

Everything else came in the CM5.0.6-N1 release.

I do shut off wireless when I leave.

Maybe you guys use the phone more than you think?

My guess, charging the phone on USB. Try the wall charger, its pumps out 5v 1A verses the USB which is ????? Heck I dunno...

Wiki'd - USB Power Spec's

The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines. For USB 2.0 the voltage supplied by low-powered hub ports is 4.4 V to 5.25 V.[33]

A unit load is defined as 100 mA in USB 2.0, and was raised to 150 mA in USB 3.0. A maximum of 5 unit loads (500 mA) can be drawn from a port in USB 2.0, which was raised to 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. Low-power devices draw at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0. High-power devices draw the maximum number of unit loads supported by the standard. All devices default as low-power but the device's software may request high-power as long as the power is available on the providing bus.[34]

A bus-powered hub is initialized at 1 unit load and transitions to maximum unit loads after hub configuration is obtained. Any device connected to the hub will draw 1 unit load regardless of the current draw of devices connected to other ports of the hub (i.e. one device connected on a four-port hub will only draw 1 unit load despite the fact that all unit loads are being supplied to the hub).[34]

A self-powered hub will supply maximum supported unit loads to any device connected to it. A battery-powered hub may supply maximum unit loads to ports. In addition, the VBUS will supply 1 unit load upstream for communication if parts of the Hub are powered down.[34]

In Battery Charging Specification[35], new powering modes are added to the USB specification. A host or hub Charging Downstream Port can supply a maximum of 1.5 A when communicating at low-bandwidth or full-bandwidth, a maximum of 900 mA when communicating at high-bandwidth, and as much current as the connector will safely handle when no communication is taking place; USB 2.0 standard-A connectors are rated at 1500 mA by default. A Dedicated Charging Port can supply a maximum of 1.8 A of current at 5.25 V. A portable device can draw up to 1.8 A from a Dedicated Charging Port. The Dedicated Charging Port shorts the D+ and D- pins with a resistance of at most 200Ω. The short disables data transfer, but allows devices to detect the Dedicated Charging Port and allows very simple, high current chargers to be manufactured. The increased current (faster, 9W charging) will occur once both the host/hub and devices support the new charging specification.
