to "calibrate" your battery all you have to do is let it completely die then completely recharge it 2-3 times in a row. deleting battery stats and running them battery calibration apps dont do sh*t. you get what you get when it comes to your battery. undervolting/underclocking the cpu/gpu, turning down the brightness, turning off wifi/gps/bluetooth when not using it, installing better battery stats to check for "rogue" apps and removing/killing them will all save your battery life.
i think you shouldve waited for the $100 google tab thats being released after the new year tbh
also, you dont want to let your battery completely die all the time though. you want to let it die a little bit, then recharge it, let it die a little, then recharge it. this is less stressful on li-ion batteries and will extend the battery life/health.
That's for the knowledge. I found out the calibrating made little difference and that could of been placebo effect now that you have linked proof. However, to counter it's abysmal battery I did find an app called
that did WONDERS for the battery. It extended the battery life by 1.7x which is nearly double what the battery originally was. Keep in mind though, I keep screen brightness at the lowest and that app does alot of sh*t like disable WiFi when I don't need it and sh*t so I don't receive notifications when I'm not using my tablet, but it has done WONDERS
for this tablet and made it actually viable to carry around.
I keep hearing rumblings of a Google $100 tablet but until it's definite I think it's silly to wait and hope.
