Help Touchpad Battery Draining Issue

T

Hello everyone,

I'm pretty new to the Android scene. I've jailbroken a number of iphone/ipads/ipods, but after purchasing the Touchpad, I just knew I needed to get Android running on it. The limitations of Web OS were just too many.

I have had android running on it for a couple weeks now. Starting yesterday, the battery would just slowly drain even while plugged into AC power. I tried re-booting, tried plugging into a USB adapter on the computer but no luck.

The only thing that has worked is booting into Web OS.

Obviously if the battery works with WebOS, the issue isn't the battery or cable, but must have something to do with android?

Has anyone run into this issue, and can someone point me in the right direction?

Any help would be GREATLY appreciated!
 
I had the exact same issue. I use my TP to read Comics and Mags and I would pull it off the charger at 100% and within 10 minutes I would be down to 90%. Someone told me the reason was I upgraded from CM7 to CM9 without doing a full wipe. I didn't buy it but gave it a shot and it resolved my issue.

Yes, when changing roms you should always wipe unless the dev specifically says you do not need to. Not doing so can and has caused many issues on a variety of devices.
 
Thanks for the replies.

The screen has always been off when trying to recharge... doesn't seem to make a difference though.

I didn't upgrade from one version to the other either, and it was running fine earlier.

If I do a fresh wipe and start from scratch... where would I begin? How does one wipe the system without messing up the Webos?

Thanks for your help.
 
Found these instructions at another forum, but followed them and they worked perfect:

Do the following for a simpler and more reliable ICS CM9 Alpha install. The idea is to keep it simple:

1. Download
2. Backup
3. Clean up
4. Install
5. Restore (if you used Titanium Backup or other apps to save apps)
6. Be happy

There is no 100% guarantee, but from what I have seenI believe below is the approach that is most likely to be successful.

Download

Download the four files below to your TP.

- CM9 alpha .6: (Techerrata Downloads - Downloading update-cm-9.0.0-RC0-Touchpad-alpha0.6-fullofbugs.zip or Goo-inside.me Downloads - Downloading update-cm-9.0.0-RC0-Touchpad-alpha0.6-fullofbugs.zip)

- Patch for the power menu reboot issue with 0.6 where TP shuts down instead of rebooting. From Dalingrin and team: http://ergh.org/cmtp/

- Gapps 4.0.3 v11: http://goo.gl/u9s8g (People have also had success with teameos gapps: http://goo-inside.me...s/teameos/gapps)

- Gapps fixer: http ://goo.gl/UM5Ik (You should not need this, but should have it just in case.)

2. Backup

Backup installed apps or data (bookmarks, game status, etc.) in Android, using apps like Titanium Backup (TiBU) or MyBackup Pro/Root.

(Note: Previously, on ICS Alpha .5 only TiBU version 4.0.2 (http://www.wuala.com...kup 4.0.2.apk) worked unless you applied a patch, but as of Alpha .6 the current release version of TiBU works w/out issue.) So don't worry about that any more...

Boot into ClockworkMod Recovery (CWM).

Back up your current ROM in CWM (also known as a "nandroid" backup) using the Backup/Restore menu.

3. Clean up

Still in CWM:
- Wipe Data/Factory Reset
- Format System (under the Mounts and Storage submenu in CWM)
- Format Data (if you're superstitious...wipe data/factory reset already did this, but I know some people still want to later, rinse, repeat. ;-) )
- Format Cache (if you're superstitious...wipe data/factory reset already did this, but I know some people still want to later, rinse, repeat. ;-) )

While you're in the Mounts and Storage submenu note the Mount USB storage option - if you get into trouble after the install, you can boot into CWM and use the Mount USB Storage option to mount the internal storage to your PC via USB to manage the files on your TP SD card from your laptop.

4. Install

Still in CWM:

Flash the following files using the Install zip from SD card option.

- ROM: update-cm-9.0.0-RC0-Touchpad-alpha0.6-fullofbugs.zip

- Alpha .6 power menu patch: update-cm-9.0.0-RC0-Touchpad-a0.6-reboot_fix-signed.zip

- Gapps: gapps_ics_4.0.3_v11.zip or EOS_GApps_ics_4.0.3_v10.4.zip, whichever version of Gapps you downloaded.

Do not flash Gapps Fixer yet...you should not need it with the recent Gapps versions.
Reboot...after rebooting and signing into your Gmail account, Market should auto-restore all your apps. If not install from market or from your backup.

5. Restore

If you used TiBU or other BU software, restore apps if they don't restore from the Market, or if you just want to restore them quickly. Generally, restoring data for apps may cause problems, but should be fine for games, apps that need log-in information, etc.
If you have problems with Market running or sync for email or calendar, you can try flashing the Gapps fixer zip file.

If you have ulmage issues (boot fails, messages about insufficient space or improper ulimage size, you may need to uninstall CM9 using the acmeuninstaller, and then reinstall CM9 using CWM. Check out this thread for more info/options:

http://rootzwiki.com...6-boot-failure/

The old truths are right - do a clean install on a ROM change or significant update. Using the acme option to try to keep data can be quite iffy...may work fine for some, but for most users it's not worth the potential hassle during and after install. If you do install from CWM, you must remove existing data first, per above steps.
 
This should work on CM7 or CM9.

Boot into recovery.
Mounts menu: format data, format cache,
Advanced menu: clear Dalvik cache

Reboot.
 
Thanks guys. Great forum you have here!

What is the "Dalvik cache" file? That route seems ALOT easier than doing the full wipe and re-install, but if push comes to shove I'll do that.

Looking forward to getting this Touchpad running properly again.
 
The cache and Dalvik cache are just folders with optimized files that are used to speed up Android. When you clear them, it takes longer to boot the first time, but it's needed when updating roms and clearing them occasionally fixes problems.

If you have issues like a boot loop or other problem, deleting the files in both those caches (and fixing permissions) is one of the safe things you can try. Formatting data means you lose apps and settings so you'd want to do that only if you have serious issues, since you'd have to reinstall apps. CM9 is really good about getting your apps back tho, much better than CM7, which quits at the first error.

In this case, formatting data is probably all that's needed, but might as well do the rest while you're there.
