Re: Can you uninstall lollipop 5.0 and go back to 4.4.4 kitkat?


I experienced the same issues of major battery drain. It was improved slightly after updating some apps.  But the single best improvement came after I performed a cache wipe and clean install using Samsung Kies app from my PC. It backed everything up for me, just in case. After the wipe and reinstall of Lollipop, I did NOT perform a full phone restore. Instead, I let google restore all my contacts and mail. Then I re-installed all the apps I wanted to keep from the google play store. Then used Kies to restore only critical setting like network, sms messages, photos and music. I now have a perfectly smooth running S5 again and better battery life then Kit Kat!!   I'll admit it was a little painful but it only took a half a day and I have learned a lot about Lollipop. It was well worth it.
