HP TouchPad Battery Drain issues during sleep

The Problem:

Developer James Sullins, Aka Jcsullins, has informed HP TouchPads users that there is a problem with our tablets A6 Firmware. This issue can cause an usually high battery drain during sleep. This problem occurs overtime while running both CyanogeMod and WebOS, on the HP TouchPad. As a results the Touchpads battery drains more quickly with daily use and the overall life span is reduced.

The Solution:

Reflashing the A6 Firmware effectively fixes the problem but may need to be repeated as a part of regular HP TouchPad maintenance. Watch this video and follow the step by step instructions to reflash your own Touchpads A6 Firmware.

How to test:

How to monitor your battery

To monitor your battery drain history during sleep install the free app Battery Monitor Widget:

-Once installed open the app and go to history to see a log of your devices sleep history.

-To setup the Battery Calibration correctly for the HP TouchPad,

-go to BMW settings/calibration/Battery capacity/ and set it to 6300 (*f29c), 6000 (*i29c) or 5800 (*s29c) and tap OK

-Note* See the Battery p/n # on the original packaging.

-Note* after setting the calibration, users will have to allow several hours to pass before the history can be accumulated.

Or

You can also use Cool-Tools to monitor your battery drain in real time.

Additional WebOS Preware Performance Tweaks:

I would highly recommend doing the following tweaks. Read the full instructional guide in the link below:

Reduce Logging & Patch ‘em Up:

This patch require you to log into Skype with the "Phone and Video Calls" app.

Once there place a call to this number using the dialer type: "##5647#"

A logging window will launch, choose to "Clear Logs" first then "Change Logging Levels" and setting logging to "minimal".

Once done, exit the app – your logging levels are now changed.

If you have never used Preware you can watch this video about Flashing the HP Touchpads A6 Firmware.
