I was wondering about the battery drain in mine as the first day it seemed to go down quite fast. However I took a look at what was eating up the battery and about 60% of it during that discharge cycle was the screen. I guess I was just playing around with it more - resetting up things that got messed up, etc. and didn't realize it. After that, I haven't noticed any significant difference in battery drain.
My screen had fairly his percentage but even more was TouchWiz (almost 40%), which seems awfully high
Oh! I hadn't even considered TouchWiz as being a big drain. I use GO Launcher so I'm not even running TouchWiz - that may be why I didn't see the drain mentioned above.
As Oatmeal mentioned it replaces it rather nicely. The ONLY drawback is that you can't easily switch back and forth. Well, you CAN, but you would need to setup your TouchWiz how you want it THEN setup your GO Launcher how you want it. They don't share the same data for shortcut locations etc. (in case I'm not being clear, as I fear I'm not, my phone is all setup through GO Launcher - all my shortcuts and widgets are just where I want them. If I change it so that TouchWiz launches instead there are NO shortcuts or anything other than the default ones provided by Samsung during install)
Go Launcher will replace touchwiz?
GO Launcher is fantastic. And it's Free to boot! You get some really nice widgets with it as well. The switch widget allows makes turning off your data package very easy if you want to conserve your battery more.
Last night a downloaded a Jellybean Theme that looks really slick.
Re Battery drain issues. I used to get a good 17 hrs of use on LTE with ICS. I use my phone mainly for e-mail every hour or so and texts with the odd you tube video at lunch, face book etc. Downloaded Jelly Bean and now am lucky to get 10hrs out of a charge? Have checked all the battery use items and screen is set to auto with a 1min turn off time. I have even enabled energy saving mode which I never had to use and still only get 10 hrs. Went to a Rogers store tonight to enquire about the issue and they said they could send my phone back to Samsung for repair. My phone is 15 months old and is now not much use if I have to carry a charger everywhere with me. My asus Ultrabook gets 12hrs on a battery charge......... Not sure how to proceed with this. Would love to roll back to ICS and at least be able to use my phone again....
