Memory Drain, Phone Freezing, Cydia Crashing, and more. I'm at my wits end!

[Bill1975]

I'm running an iPhone 3G, iOS 4.0.1 jailbroken with Redsn0w.

Over the last few weeks, I've noticed some problems that have cropped up and are progressively getting worse

1) Safari sucks up nearly ALL my RAM. I'll go from 30 - 40 mb free to 3-5 mb. (I have the available RAM displayed on the status bar, so I'm able to monitor it)

2) Safari, and Maps will drain RAM down to 8 mb and freeze up for several seconds. I've also noticed the maps app getting slower and slower.

3) The Mail app launches itself randomly in the background, or when I free up memory in sbsettings, or launch Cydia. I've disabled backgrounding in Backgrounder, and have all Push settings turned of, yet Mail still launches itself in the background. The Ipod app sometimes does this as well.

4)While trying to download an update to a theme, Cydia has crashed 3 or 4 times in a row.

Any ideas? I previously had no problems but it seems like my phone is getting slower, and wonkier. I don't know how much of it is jailbreak related, since it got a bit slower under iOS 3.0 and even slower after the iOS4.0 update.

iPhone 4, I want an iPhone 4 please.

Bump. Any ideas?

If you have multi tasking enable disable it, I had the same problems, runs a little smoother with no multi tasking.

[Bill1975]

Multitasking is disabled. I am using Backgrounder, though.

[golfing7861]

I would strongly recommend to take that out as well. It's up to you, but I think it would make a difference.

[Bill1975]

Removed backgrounder, it helps, things are running a bit faster so far. Howeber, the Mail and iPod apps seem to launch themselves in the background. Seemingly at random.

[golfing7861]

The mail app is supposed to do that, you should also change fetching email to a longer interval if not done already.

4.0 / 4.0.1 are said to be bad for iPhone 3G. You should upgrade it to 4.1, which apple said will fix the 3G being sluggish and slow. You can jailbreak with redsn0w, but there's no unlock for 4.1 at the moment. If you rely on an unlock, wait till 4.2 and an unlock for both 4.1 and 4.2 is getting released.

^ +1 for upgrading to 4.1

4.0.x runs horribly on the 3G. If you rely on an unlock, you can also use custom firmware (PwnageTool for Mac; sn0wbreeze for Windows) to upgrade to 4.1. You won't update your baseband this way. 4.1 by itself will already be a bit faster, but if you want to improve performance even more, disable multitasking and keep tweaking/theming to a minimum.

As for Mail running randomly in the background, your fetch setting (General > Mail, Contacts, Calendars > Fetch New Data) is probably set to every 15, 30, or 60 minutes. If you want to avoid this, simply set it to fetch "Manually". This way you'll only have Mail open when you open it yourself.

Thanks!!! I will update to 4.1 and re jailbreak. I don't need an unlock, So I'm good.

As for the mail app. ALL of my fetch settings are set to manual, and Push is off. It rather defeats the purpose of being able to set it to manual if it's going to spring anyway. I suppose it isn't a huge deal, but I like to keep memory usage to a minimum.

Good stuff, be sure to post back here and let us know what you think of updating! I'm positive that you'll notice an improvement in speed/memory

[Bill1975]

I updated to 4.1 and noticed a big difference! After updating I re jailbroke the phone, and while it's still faster than before, it seems to have slowed down compared to running 4.1 without a jailbreak.

Specifically, compared to 4.0.1, maps is a lot faster, and there seems to be more free RAM. Texts still opens slower than I like and there is still a bit of a lag with the calendar, but the os update has helped.

Not sure how the jailbreak slowed the phone back down though.
