3.0.1 battery drain

I updated my 3GS (32GB) from 3.0.0 to 3.0.1 the moment it was released a while back and ever since my battery life has been awful. I changed no settings, installed no new applications and didn't leave the country.

So after a while of being annoyed and dreading a possible trip to an Apple store, I removed 3.0.1 and reinstalled 3.0.0... now all is fine again.

I have been frequently inconvenienced by the arbitrary / seemingly random nature of Apples approval and application rejection processes... Why they don't apply the same rigor to their own releases?

There is no difference between 3.0 and 3.0.1 besides the 48kb where the SMS hole was patched. So that shouldn't be what was easting your battery.

Cheers for the reply... What do you think it was then?

- Avoid programmes like SBS ( which will be resident in Iphone memory)
- Turn off 3G/ Location services / Wifi /
- Set Network selection to Manual.
- Auto brightness off / select your comfortable one
- Push off / set all mail accounts to manual.


these are some points but tell me some things will really matter iphone isnt it?

Doing this will GREATLY increase your battery life. Probably by 2x at least.

were you jailbroken and did you restore from backup after updating to 3.0.1?

There is a known issue of poor battery life with restore from jailbroken backup. Solution is to reload 3.0.1 and set up iphone as a new phone, then resync your contacts, music etc. You lose SMS and call history (but this can be restored with a bit of effort if you keep a copy of your backup from before the restore.)

The other likely cause is push notifications, if you hacktivated, you need to install an app that includes push notification menu so you can access the menu in settings to properly disable the notifications. Otherwise your phone battery will drain very rapidly due to push notifications being difficult to get working properly on hacktivated phones.

Hi there...!


I just got my 3GS today - which is officially unlocked and jailbroken. I had bluetooth and WiFi on. But the battery seemed fine with me. Im also o 3.0.1.

As gkscit said, turn off all unwanted services and processes. It will increase your batter life alot.

cheers

Oh, also be sure ssh is not running when you aren't using it.

This is not necessary, the way ssh is installed these days means that it uses zero cpu unless you have actually got an active SSH connection.

Turning off SSH (or VNC if you have that installed) when not using it is good security practice as it reduces the attack surface if others are trying to break into your phone over the network.

Changing the default passwords is also good security practice.
