Is it necessary to intentionally reboot? I have always considered any reboot to be a major annoyance. My galaxy tab 7.0 plus running honeycomb used to randomly reboot on its own almost once a day and I would be forced to reboot a couple times per week when some app froze. I updated it to jellybean a few months ago. Now there are no more random reboots and it only freezes one or two times a month requiring a manual reboot.
I have a friend that works in the cell tower business who supplies the carriers with their towers. He suggests turning one's phone off once a week. That insures that any updates they do to insure the best call quality and LTE connectivity get successfully pushed to our phones immediately. Therefore I make sure my friends and family are aware of this practice which I follow regularly.
I have 3 batteries.. I like to swap them out..to help keep them stored and cycled. so about every other week.. I swap 1 battery.
Itd be similar to a weekly prl/profile update on sprint. If your area is under NV, it can certainly help
This is totally unnecessary. If the phone is capable of applying a system update, it will do so automatically without a reboot. It only needs to refresh the connection. However, it is a good idea to replace your SIM every year or two to take full advantage of any system updates. Sometimes makes a difference, sometimes not, but a fairly recent SIM removes doubt about capability. I have a brother-in-law who has supervised building cell towers and installing the equipment for 15 years for various companies all over the country. Turn-key, from bare ground to sending signals. Also know a Sprint engineer. Mobile communications is an amazing industry.
I probably reboot my phone less than weekly but more than twice a month. I'm in the reboot when stupid becomes annoying. My PC gets the same sort of attention.
I've noticed that once in a while, my music while playing over my BT audio in my car would stutter. When this happens, I just reboot my phone and that fixes the issue. I haven't figured out why that is. It's been happening about once a month or so lately which isn't too bad.
