Greetings from ireland, cuchulainn here.
I've recently updated the software on my galaxy s. Now running androids 2.2 Froyo. I didn't do a factory reset as it seemed a lot of hassle, losing all my apps and stuff...( admittedly it means the phone lags)
Since changing to Froyo 2.2, my battery life is now appalling. It doesn't even last a day, used to be about a day and a half which was ok. Even without playing games/watching videos/going online my battery is still dead by 9pm.
I've also noticed that while idling, ie no apps open I'm using 200mbs ram. Having cleared level 1+2 in ram manager in task manager, it's still using 150 to 160mbs ram... Is this normal? Does the operating system really need this much ram? And does this explain why my phone is no longer really suitable to use for its core functionality as a telephone??
Any ideas on how I can extend battery life, our maybe operating system I can use would be greatly appreciated ,
I think 150-200 MB. is normal.
Battery life doesn't depend on ROM. It depends on first of all Settings.
Some of my Settings:
1. Wi-Fi: Network notification not ticked.
Sleep policy: When screen turns off ticked.
2. Mobile network settings:
Use packet data and Data roaming generally not ticked.
Network mode: GSM only ticked.(generally)
3. Syncronise: Auto-sync not selected.
4. GPS switched off.
5. Screen turned off when it's not in use.
6. Juice Defender,Juice Plotter and Advanced Task Killer help me,too.
