Help 2.3.6 Battery life sucks

Over the past few weeks, before the ICS update, I realized that the biggest consumer of battery power was the wireless connection. As long as I had it turned off when not actually using it, the batter would end the day with about 70 to 80% battery remaining.

I just upgraded both of our phones to ICS last night and I left the wireless on. As of now, about seven hours in, the batter is still at 87% which is a LOT better than it was.

One thing that seems critical is that you calibrate your battery as described earlier in the thread. If you don't do that, the operating system on your phone simply won't give you accurate information and likely won't allow you to use the whole charge on the battery either.

Hi guys, I'm new and this is my first post. I noticed after the 2.3.6 update my battery life was sucking too. So i googled it and found this thread.

After reading every post I learned that most of you guys had wifi turned on and once you turned off wifi that the battery life improved dramatically. Well, here's my situation:

I NEVER use wifi, I always have it turned off, and my battery life still sucked after the 2.3.6 upgrade! Grrrr... I also noticed that after the upgrade the following items were taking most of the battery:

-Cell standby
-Android system
-Android OS

First off, cell standby should only register during the periods of time where your phone can't find a signal. Before the update, cell standby would only use a small percentage (like 2% percent) because the only time I was without a signal was in an underground parking garage. Now cell standby takes about 15% percent, and when I click on details, it usually shows "time without a signal: 0m." In other words, it's NEVER without a signal, so this should not take ANY battery life.

Also, Android system and Android OS would usually take only 5 - 10% percent (combined) of the battery life before the update, but now they are taking about 30%!

WTF?!?! I'm going to try and do a few full battery cycles like others have suggested and see what happens. I have a feeling like the OS might just be reporting the battery life incorrectly because, just like the battery has been draining faster, the battery has also been charging a lot faster too. So this makes me think...

I'll update this thread in about a week and let everyone know what happens.
 
I found suggestion to download Battery Defender. Did. Followed instructions and my battery life is awesome. I can now go days without recharging.
