There are several apps I don't use on my Motorola Bionic that were pre installed on my phone. Some are gone since Ics update and some I was able to delete. My question is the one I'm stuck with should I be updating them when a update is available or just leaving as is. Is there a difference in memory doing the update. Will my phone use more battery telling me you have a update what. Info would be great , these apps are sometimes the only reason play store tells me I have a update.
