Battery life after ICS update

[ekmickens]

Just updated my Droid Razr to Ice Cream Sandwich and I love the OS system and is used to it because I have it on my Motorola Xoom wifi for a while, but one thing I noticed is the battery drains faster then on Ginderbread. Am I doing something wrong? HELP!!!!:'(

Have you closed all non essential apps? Maybe a good reboot will set things straight? When rooted I had the same issue. But after a reboot or two, everything was cherry.

Nope, battery seems better for me. The only time it drained fast was the night I has to download the ICS update but that's to be expected.

Just like when you flash a custom rom, it's going to have to settle in..do a couple battery cycles and should be running normal

Another thing, turn that evil 4g off...that is allowing 2 radios to work, I see you are not dl anything.

I would suggest only turning on 4g when you are downloading large files, or streaming big videos......in my experience 3g is more than fine for podcasts/music streaming.

Make sure your mobile data is not set on global. Mine was upon first boot of the ota. I keep mine on cdma/lte. There is no cdma only mode anymore.

Thanks guys and there is no way to turn 3g only on ICS. Also I'm using juice Defender Ultimate

Yes there is. Either dial *#*#4636#*#* and select phone info then CDMA only auto prl. Or download LTE ON/OFF (HTC Thunderbolt) and it will bring you to the same menu as the *#*#4636#*#*.

It's not hard to get good bat stats on idle.

Now show your on screen time, I'm guessing 40 mins tops.

Yeah but once you turn off your phone and then turn it on, it reverts back to 4G, you have to switch it each time you power on your phone or reboot it for any reason.

i have to say that my battery drains a little faster on ICS than it did on Gingerbread with all setting the same. I even froze a few apps that I thought were draining the battery.

That's a bummer but its better than nothing. I rarely reboot my phone so I'm not sure how this would be a big deal. Android seems to handle minimal reboots compared to that of my old Blackberries.

It would probably help if you stopped tinkering with your phone after the update. 70% of battery due to screen isn't an OS issue...
