    Default Shrinking 7.1 and battery life correlation?

    I've shrunk all of the OS builds with the BBH Tool and have never had a problem with the battery performance. The battery on 7.1 is terrible for me but others haven't had any issues. I am not running any 3rd party apps at the moment. I'm wondering if shrinking the OS has caused some module in 7.1 to keep looking for the missing bit of code which keeps the cpu running?

    I shrunk it before I installed it as well.

    I don't think the BBH tool can remove something necessary.

    How long has it been since you upgraded? Restoring BBM groups can REALLY use up battery... are there any groups that didn't restore?

    No groups. Been a couple of days now. Very odd.

    BBH Tool has been optimized to not shrink anything it shouldn't so you should be fine in regards to shrinking - I personally have pretty bad battery life on 7.1 as well (9810) but still relatively close to what I had on previous OS7 builds

    7.1 is a battery hog. Its not due to shrinking.

    I wondered the same thing, people who don't shrink seem to be getting 1-5%/hr drain and people who shrink get 5-8+%/hr...

    It's starting to make me rethink shrinking the OS.

    I'm going to give it a day or so more and then install it unshrunk. This is nuts.

    I hope everyone knows that 7.1 has a battery reading glitch.
    It thinks that 92% is 99 Percent.
    It drops from 100 to 92 instantaneously. (See for yourself in battery analyzer)
    When it charges, It skips from 92 to 100.

    Nope, no 92% glitch for me like on previous builds. It uniformily drains faster.

    Howdy Hank,

    I think I've seen you say that about every single build for the 9930. First the .241 was a battery drainer than .374 was the worse ever, than 7.1 is a hog. All the while you at first post saying they are the greatest battery builds ever, lol. Make up your mind!!!lol....NP,JS

    This is NOT true. I have a drain rate of 1.5%/hour according to Meterberry. But with official Telus OS 7.0 I got 5%/hour with the same amount of work.

    I always shrink my OS and with OS 7.1 my battery life improved a lot.

    NOTE: If you use wifi hotspot it will drain your battery for sure. But RIM already posted on their updated user manual that hotspot will drain the battery fast for good reasons.

    I've never not shrunk, so I couldn't say. Never had 'bad' battery life though.

    This is true, I have been all over the board and with different results depending on if I shrank or what I shrank or not shrinking at all. Where I'm at right now is, .340, .362 and .374 run the same as far as battery life. .241 and .254 also run the same battery life, but don't perform as well as the latter. For me 7.1 battery life is very very slighty lower. Not by much. If I needed hotspot I would run it. At the moment I am running .374 with lots of ALX files trimmed out and has been the best battery life I can get. I get 3-4% DRH.

    It just took a while to try everything in every possible configuration. Sorry if I seemed wishy washy.
