    Hello,
    I have been struggling with this issue forever. I am using my Google nav app and all of a sudden it freezes barely updating with CPU @100%. I have tried different options using 3g instead of 4g, not using bluetooth, not starting nav when CPU is busy nothing has worked. All of a sudden either at the start or during a navigation session the CPU will go up to 100% and the app will stop updating and if I am driving I left without directions until I reboot. Huge headache. I used different system monitors like 'WatchDog Lite' and 'System Tuner' and those apps say that the most CPU consuming process during that time period is 'Android System Process'. I have no clue as to what 'Android System Process' is doing during that period of time except it is taking a large amount of CPU.
    Only option left is to overclock, upgrade to a faster CPU from Verizon or go to Apple IPhone

    You COULD overclock, you can't upgrade to a faster CPU because its a phone (unless you buy a new phone) or get a new phone.

    Have you tried to format the phone and reload what you need, there has to be something causing the system to spike like that.

    Also, under settings/applications/all/maps....try clearing data and cache. It helps with a lot of problems...

    What phone (Droid Charge I assume) and OS version are you running? Is it rooted or stock?

    And where do you store the maps, on the device or the SD Card?

    Have you tried deleting the app and maps and reinstalling fresh? I would expect any maps stored should be on the card.

    Perhaps there is a damaged file causing instability and excessive searching.

    This is only occurring when you are actively running or starting Google Nav? No other app causes the behavior?

    My phone is rooted and is running Eclipse 2.0. Usually I note this kind of behaviour only when Google Nav is running. I didn't know that Google Nav stored maps on disk thought it always got it from the wire.

    It does but it will cache some maps for quicker loading as you travel

    Also, try a new ROM and see if it does it still

    I had this issue with stock and thats why I installed Eclipse 2.0. Don't think a new ROM will help. Probably something internal to the phone like my corporate email, or something scanning my SD card.

    Info on the caching GM can do here. You may not think a new ROM will help, but if nothing else has worked wouldn't it be worth a shot instead of guessing it might be "something" scanning your email?

    If you have a corporate setup maybe the IT people could tell you if there is any scheduled scanning that takes place.

    I have been partially able to fix the problem. One I downloaded Copilot Live as a navigation app which uses offline maps instead of downloading maps on the fly like google nav. However, still my phone used to lag close to 20-30 seconds when I would go to my home screen and similarly when I went to my application lists. I was using Seepu so I could see that my CPU was at 100% all the time. This led me to believe that there might be an issue with my SDCard and hence I downloaded sdbooster https://play.google.com/store/apps/d...dbooster&hl=en .
    I saw an amazing performance improvement after I set the cache size to 8192 mb and the lags all but disappeared. However, still when I am on my home screen it sometimes lags 5 seconds which is still infuriating. What the heck is it doing, is it reading apps from the disk?
