[Acer Iconia A500] ktmdave7:
I disagree, i'd say do complete wipe with TWRP 2.4.0.0 and reflash a MD5 check'd ROM, and you'll be believer...

Also have settings set correctly. I'm gonna reflash ROM and give you a Section on bottom of post#2 for settings after a default install..

FOLLOW that , then sleep on it for one NIGHT!

I will even install my normal apps afterwards, and give results over next few days and pics if need be.

you can also read Reviews on MY SGS3 Stock Slim ROM... Nothing but GREAT Results in all my WORK!

for now read post #2 on my SGS3 rom for similar changes..most important is TURN the 3 GPS settings off (unchecked)

Google maps will eat u up. also next time check what is useing your battery up (Settings - Battery)...that is better to justify your comment!

you can take Screen shots and post image info on post#1 for screen shot keys!

Tip: Great Settings to save BATTERY!!!

Changing all the ones from Default settings only!

Settings - Wi-Fi - Settings - Advanced - Network notification {uncheck box}

Accounts & sync - "OFF" {manually do this when you want to sync stuff... contacts, calendar, etc}

Settings - Location services - "Use GPS satellites" {uncheck box} {major battery drain}

Settings - Security - "unknown sources" {check box} {Optional: needed for install .apk's from SDCARD}

Settings - Language & input - Android keyboard {settings} - "Vibrate on Keypress" {uncheck box}

Settings - Language & input - Android keyboard {settings} - "Sound on Keypress" {uncheck box}

Settings - Language & input - Google Voice typing {settings} - "Block offensive words" {uncheck box} {less checking = more battery}

Settings - Backup & reset - Automatic restore - {uncheck box} {do this 1st}

Settings - Backup & reset - Back up my data - {uncheck box} {do this 2nd}

Settings - Date & Time - Automatic date & time {check box} {Optional}

Settings - Developer options - USB debugging - {check box} {Optional - needed a lot}

Go to Settings tab lower right... Settings {symbol} - Notifications - "OFF"

Run "Market" - Settings - "Notifications" - {uncheck box} {don't need it checking, do it manually}

Run "Market" - Settings - "Google AdMob Ads" - {uncheck box}

Settings - Wi-Fi - "OFF" {turn OFF, when not using (test with off 1 night, test again with on = knowledge of worth it or not to disable}

always Have these settings this way...

Settings - Sound - Touch sound - {unchecked box}

Settings - Sound - Screen Lock sound - {unchecked box}

Settings - Sound - Vibrate on touch - {unchecked box}

Settings - Display - Brightness - Automatic brightness - {checked box}

Settings - Location Services - "Google's location service" {uncheck box} ...Drains battery while your sleeping

Settings - Location services - "Use GPS satellites" {uncheck box}

Settings - Location Services - "Location & Google search" {uncheck box} ...Drains battery while your sleeping (Browser + Maps will use it)

Edit : for POST BELOW...

best to not use TB to save settings after u make them on the rom your FLASHING back to... I use it for all my passwords, usernames, settings, wallpaper, etc...

-but always make new saves (to later restore) if on new rom (cus you could be adding back extra non used or bad files that change depending on certain Rom's)

Screen @70% is problem, no apps in STOCK slim are turning that on (while your sleeping)

Wi-Fi 9% isn't helping..if your tablet was strainging to get signal lock or searching too much that can cause that to use battery, i usually leave mine on,

-test out 1 night with off and another with on, then you'll see what happens and get knowledge of worth it or not.

Settings - Apps - "RUNNING"... notice Ram used + how many running apps after a start up +3 minutes

(Google Services, Android keyboard) settings is on cus your using that app now to see this screen (normally that is off)
