Battery life post ICS update?

I have 2 Razrs and I did the same things to both and now both are getting remarkable battery life. First I took Network Mode off of Global and selected LTE/CDMA as the preferred network. I also wiped the cache part. on both phones.

I also noticed that if you do not change the network mode from global to LTE/CDMA and you try to use LTE on/off to set it to CDMA, it won't stick and will somehow change itself back to 4G.

One or both of those things helped alot.

Tryng the LTE/CDMA swap.

Basically, it's searching for the other radios when you don't need it to?
 
It might be searching for those other networks, I don't know for sure. One of the phones I keep on CDMA only and I noticed it wouldn't stick unless I unselected global in preferred networks. The battery drained really quickly and I noticed it would be using 4G even though I had set it to CDMA twice. It might be the wipe system cache procedure that actually did the trick or a combination of both. I always reboot after changing the setting.

How is your battery life, post ICS update? Mine seems a little low(I have the MAXX). Before the update, I could get to work(at 8am) and be at 60% by 4 or 5pm that day, now it seems like I get to work and I'm down to 50% by noon. My phone use habits has not changed(general texting/checking emails/browsing the internet when I go outside with buddies to smoke).

Thoughts?

Seems to me that the battery is lasting longer but I can not be sure.

I'm getting great battery life on my Maxx and I leave wifi on all the time, even at night, and do not have any smart actions set to disable it. On the screenshot I posted above, after over 3 days of usage, wifi had used only 4% of my battery. I'm in wifi coverage about 90% of the time and I believe this saves a lot of battery vs being on 3G/4G.
 
Seems most of the issues are some of us Razr thin users....

Will turn off global to see if a factor.
 
From another post I did tonight:

Before ICS, I could stream Pandora at work on 4G, no battery saving measures taken, and after 5 hours be at 70%. Now, it's 50-60%.

I saw that second to "mediaserver", facebook was the second highest battery user (I had my screen off except when I was using my phone) so the next day I did everything the same but shut off Facebook and Instagram. Slight difference. 60% instead of 50%.

To make it weirder, it hardly charges at work during my half hour lunch. 10% bump if that. Before ICS it was 20% charged during that same time.

I made a few extra stops on the way home but did 1-1.5 hours driving, phone plugged in, Pandora again screen on, never went up.

What the heck?

I just factory reset, and got everything back up and running. I will see what this does.
 
This is the easiest way I have found.

there are many more choices in the drop down menu, not all work with this phone

Yesterday I turned off wifi and battery life was fantastic. Overnight with wifi off, it only dropped 5%. (Previously with wifi on it would drop 20%-30% overnight.) I know others leave wifi on and have no problems. It's a mystery to me, but I'll keep poking around.

My experience is that with gingerbread (haven't tried with ICS) that in 7 hours of sitting there on a solid wifi signal, it would only go down to 90% from 100%. It guess it depends on other things, what's running, etc.
 
Last weekend prior to ICS, I woke up to a full charge, went golfing at 8am and used my Golfshot GPS for 18 holes. When I was done at 1230, I looked at the phone and it was at 79%.

This morning (with ICS now for a week), I woke up again to a full charge, went golfing at 810am and used the same GPS for 18 holes. When I was done at 1210, I looked at the phone and it was at 60%.

Everything else was constant, no other apps installed, no phone calls taken or text messages.

That is a huge difference.

what kind of clubs are you using?
 
My phone drains so much now! I took it off the charger and in two hours it went down to 70%...that's a huge difference! I literally use it for 10min and it drains 10%

While I can't tell yet what it does on my work days, factory resetting seems to have helped my battery life somewhat. After ICS, the phone didn't seem to know what the battery level really is. Seems impossible for a battery that size to drain that quickly, even if you were keeping the screen on full brightness, and streaming movies through LTE. If it's too BAD to be true, it probably is...
 
I did factory reset and it seems worse now....like right now logging on here and browsing has drained 10%
 
Well, I was removing apps, and changing settings the past few days (including a factory reset) trying to figure out why my battery was draining so quickly. Once I turned off wifi, my battery life zoomed. Now overnight it only drops 3%-5% (as opposed to 20%-30%) and right now it's been running over 27 hours and is at 46% with light to moderate use. I'll be turning wifi back on in the next day or two to see if I can recreate the problem.
 
My Razr is just as great in sleep mode as before, but it is when using the device that things are not good. 4G is worthless now and even 3G uses more power. Same song with 3D games or Flash video.

OS is super smooth, but I would trade for less smooth, to get the battery life back. Irony.


I agree with a previous post that it might be the kernel.
 
Well, i hope they send a patch to fix this issue. My battery life still sucks horribly and my Smart Actions isn't working well with ICS. It works when it wants to. I have deleted my one rule and recreated it, but it is still giving me issues AND I have done a factory reset.

I was so looking forward to getting ICS, but after having it for 8 days and the issues I am having, I would rather have GB back! I did not have one issue with GB. Since the update, my battery life is horrible, my Smart Actions works intermittently, I am having issues with my wi-fi connecting and I have had the phone lock up and freeze several times.
 
I'm having wifi and 3G connection issues too. Not one problem with this until ICS. But, I only had my phone for about 2.5 weeks before updating to ICS.
