I did a clean install with the LSRT
nothing turned off running in the background, hey cortana on all the time and I am getting battery life about the same as what Indistinguishable is reporting with similar phone use
Would a factory reset after the fact have the same result. I didn't reset when I updated to denim
if you are not getting battery life to your satisfaction I would do a factory reset imho
it should have the same effect returning your phone to the factory state with all your personal files, settings, music, etc. erased from the phone that I did with the LSRT
I usually just bite the bullet and do a factory reset after getting any major OS/firmware update because in my case it has always minimized problems
if you do a hard reset or use the LSRT wait for a couple of days and battery charge cycles to get an idea of what to expect for battery life with 8.1.1/Denim
the first time I used the LSRT I restored a backup to see how well it would work and save me some time but I started to get some of the same nagging problems with a few app live tiles I use not working properly so I nuked my phone again with the LSRT a second time and did not restore a backup and put everything back on manually and everything is working fine now and battery is life has been goodDo you restore a backup to or no?
