Here's a quick & dirty guide to stop loosing your quick flushing out battery on your android mobile. Follow this and you'll surely save a lotta it. We have tested this on SGS2 and Moto Defy and the battery drain has reduced by a marginal percentage.
- Use 2G-only if you don't need 3G
- Monitor programs which cause wake-lock. use betterbatterystats and either uninstall or tweak them
- Do not use task killers. see the previous item and find the malicious programs instead of repeatedly killing them.
- Do not activate google latitude on maps.
- If you don't need pushmail, uncheck gmail sync and use k-9 mail to pull mail, lets say, every 1 hour or so.
- Go to settings / location and security. disable "use wireless networks" and "use gps satellites". enable them when you need them, other than that keep them disabled.
- Disabling auto-brightness and using a low brightness level helps. do you know that you can adjust the brightness by swiping your finger across the notification bar? try it...
- Using juicedefender may help, but it may also cause more drain. test it yourself.
- If you need more speed than 2.5G (i.e. edge) disable HSDPA (*#301279#, select 2 then select 1). you will have 3G instead of H(SDPA) and I think it is fast enough
- Disable fast dormancy. dial *#9900# and disable.
- Disable auto sign in for google talk (search for talk in appdrawer and use settings to disable automatic sign in)
- Disable samsung update and don't use samsung gadgets if you are not in love with them. (this part may be taken care of the rom developers)
- Try several radios. I recommend you to try KE7, KG2 and KH3 and choose the one which suits you best. KG2 seems to be the best for me. however, in terms of battery life, there is not much difference between those three.
- Be aware that more you use your phone more the battery drains don't complain like "my battery drains quite fast but I did not use my phone. I only played angry birds for hours without making a single call" or don't expect to have a decent battery life if you use your phone as a computer or download torrents using your phone.
- Don't be a fool to believe "wow! 3 hours with screen-on and I'm still at 99%". That happens during battery calibration. Do not judge the battery during the calibration, judge the battery performance AFTER the calibration once you have depleted the battery completely and recharge it. you'll notice that during the calibration your battery will seem to last longer and that is why it is called "Calibration".
