OS7.1 Battery Life?
For those who have upgraded to OS7.1, please post your review of the associated battery performance.
Although I would like to have the most current OS on my 9930, I am hessitant to upgrade from original OS because battery life is currently acceptable for my usage requirements.

Not so good with 7.1
There is a sawtooth battery life thingy with the sprint 7.1 and it makes it very unreliable.
You have to think about 92 being 100% because it drops from 100 to 92 instantaneously.
Once again, It isn't as good as the other OS's.

I installed 7.1 on my Torch 9810 yesterday. Love it. The battery life today was greatly improved over my last 2 OS. I had 7.0 .261 and .585. Both were terrible. I took my phone off the charger 14 hours ago and I'm down to 14% now. Usually I would have had to put it on the charger about 4 hours ago. Also in my "office" at work coverage is spotty and my phone spends a lot of time searching for a signal, so I'm pretty happy with this OS...for now. I realize its only the first day. We'll see how it is a week from now.

I have had terrible battery life with 7.1. I have tried it three times.
With .374 I was getting 3-5% discharge rate
With 7.1 - I was getting 8-15% discharge rate
Perhaps this only happens to CDMA 7.1 users?

I just got it last night. besides other glitchy things it's doing, like losing connection to the network seemingly at random, the battery seems to be running down quicker than before. I even deleted some apps that i thought might be draining the battery to see if that had an effect. I'm still experimenting but it doesn't seem to be as efficient with power drain as before the update.

I have been running 7.1 for a few days, and having horrible battery life, right now metter berry is showing a 5.7% discharge rate, the battery is at 70% and its been off the charger for four hours maybe with very little use.
So I am going back 7.0

1st reason: meterberry is NOT necessary, since 7.1 comes with a very accurate analysis app baked in
2nd reason: meterberry uses resources...which means it IS drawing from your battery
3rd reason: meterberry hasn't been optimized for OS7 or OS7.1. In fact, it hasn't been updated since Sept 1st 2010.
Remove it, and watch your battery improve

I would actually agree with this, it made sense to me that MB, while it does work, isn't ready for OS7 devices. I wasn't having real problems with it, though I noticed after removing it my already good battery life improved.
As far as 7.0 vs 7.1, battery life didn't swing one way or the other after upgrading from .374 to 7.1.

7.1 for me and battery life has been horrible. I have had it for a few days now. I can leave my phone on the charger all night. Then i take it off and send a bum or two WHILE on wifi and it will drop down to 80%. Its annoying to say the least my avg discharge rate currently is 12.3% an hour. Also since upgraded I've had a huge memory leak so far today I've lost 45 megs.

How did you all do the upgrade? I'm using a 9810 and I'm running the 184.108.40.206 and battery life is great.
I did it this was. Setup device switch, saved to my microsd card. Then full backup with desktop manager. Then wipe with jl_cmdr. Then I did the install. Then restore with dm and device switch copy from microsd
After I did a batt pull before bed for the first 3 days and all is very good indeed
Just thought I'd share. .
