Welcome to YABD – Yet Another Battery Drain thread
or Everything you wanted to know about Battery Drain but was too afraid to ask about
Corrupt media database
Explanation: thumbnails and some database's could get corrupted making the media scanner running berserk, resulting in battery drain.
Fix: Using SGS Tools, Press [Apply script] select [clean_thumb_db.txt] and execute the script, this will delete the files that might get corrupted and reboot the phone so the database files and thumbnails get recreated.
WIFI Bug
Explanation: This is a mix of bugs and wrong settings, hardcore found some leftover debug code in the driver, tc80tc80 tested different routers seeing this effected the WIFI too, other users reported that the distance to the router effects battery drain as well. On top of this there are some settings that makes the WIFI running all the time that are not easily found.
Fix #1: Check your settings,[Wireless and network] select [Wi-Fi settings] uncheck [Network notification] press the menu key and select [Advanced] in [Wi-Fi sleep policy] select [When screen turns off]
Fix #2: See if you could try your phone with another router and compare to your home router, also check your signal that you have good coverage on the WIFI.
Fix #3: Use an updated Kernel, either hardcore's or trasig's and apply the wifi-fix (wifi-driver from JPA): View attachment update-wifi-dxjpa.zip
SGS Email 2.2.1
Explanation: The new email client has a bug making it drain the battery a lot if you set it to update every x minutes or manual update instead of push (exchange accounts)
Fix #1: Setup your account to push both on peak and off-peak, if you use imap or pop you can't do anything.
Fix #2: Use another email application, K9 or Improved Email have been reported to work much better. If you remove Samsung email you might need a fix if you have applications using your camera available here:View attachment CameraappsNoEmail.zip
Battery not "calibrated" - we don't have real facts on this one yet, so consider this our best guess
Explanation: It is said that the battery looses track of it's capacity (or rather the phone does) so it needs calibration.
Fix #1: Always flash new ROM:s with full battery.
Fix #2: Follow the guide TechnicR have on recal:
· Turn phone off and charge till full
· Start recovery and wipe battery stats
· Reboot and start the phone
· Use it heavily until it turns of by itself
· Connect charger and turn on the phone and wait until fully charged
Hardcore 256Hz vs. 500 Hz
Explanation: this is the system tick in the Linux system, number of interrupts per second for timesharing, gives a smoother appearance
Fix: None needed, the difference is not noticeable in battery drain.
Battery level drop to 95-98% when disconnecting charger
Explanation: We are used to that the battery is 100% chraged when we disconnect the charger, but with 2.2.1 we gat anything from 95-98%.
Fix: Not needed, this is a change in the charging cycle to prolong the life of the battery, but please take this in consideration of reporting battery drain, start counting from the actual value and not from 100%
For more info, check under Expert witnesses in the next post.
Could someone help me to explain the following phenomens as they are mentioned in so many various ways:
3D Gallery bug
Sensor driver hangs
Auto rotate bug
Link to my current phone config and battery life:

If you wan't to support me more than by contributing to this thread, consider if you would like a easy and automatic backup for your PC, 2Gb free plus a 256Mb bonus space for both you and me, thats 2.25Gb of free backup space for your mail and documents (and anything else you want) and for each referal you make in the future you get an extra 256Mb space added to your account.
