Originally posted this on Androidcentral: I found this post on Verizon's Support Community Forum: However, if the stock Amazon Mp3 is similar to one that was installed on my Eris, there is an easy fix for it. Go to the market and search for Amazon mp3 and see if it give you the option to install. If it does, go ahead and install it. After install open up the app and make sure the "monitor connection" is unchecked. Back out of the app as normal. On the safe side, check your applications under settings and select Amazon mp3. From there check if the "force stop" button is available. If it is press it and click okay in the dialog. If not the app is already stopped. Either way it should remain stopped and showing up as a process that appears "active I tried it on Friday and it works. You may not have to update the app as the poster suggests to kill it. The Amazon app appears to always be calling out to its Mother Ship for updates. Turning Amazon off seemed to make a significant difference in my battery life. After the Froyo update, my HTC 2150 A battery was draining at a much faster rate than it did before. Yesterday, I turned my phone on at 7 AM and killed Amazon MP3 at around 11:30 AM. I had little usage prior to the kill but afterward, I had three calls for a total of 65 minutes and the battery showed 95%. Before shutting the phone off at around 10 PM, I searched Market several times, updated an app, had several text messages via Handcent, did some light web surfing via Dolphin HD and played a few games. At shutdown, the battery showed 83%. Since the Froyo update I haven't seen anything close to this so it could be that Amazon MP3 is one of the big battery killers. Update: Amazon MP3 Store remains closed after taking the steps outlined above. Yesterday, my phone got almost no use (no calls, some weather checks and a few other minor apps) and after 15 hours my battery still sat at 100%. It remains at 100% today after light activity (no calls, some texting and other mild use)That's what I was used to seeing pre-Froyo. After Froyo I would have normally seen drainage with even that light a demand. It's too early to say "absolutely" but I am becoming convinced that the Amazon app's frequent use of the phones radio to call out is one of the main culprits in the battery performance.
