    Hi all.

    i am almost positive that after JailBreaking my iPhone 4 (IOS 4.0.1) my Battery Performance has degraded.
    i can leave my phone on standby and see the battery goes down 10% in the space of three hours. if i use it it will even go quicker in a rate of almost 1% per min of use.

    dose anyone else has experienced the same type for performance degrading ?
    i have now restored my phone to original fresh IOS 4.0.1 and still did not jailbreak to see how things are.

    had a quick search and some people said "mobilesubstrate" drains their battery....

    Any input will help.

    Thanks

    I'm guessing you mean it was Signal causing the problem because I'm not having any battery issues with SBSettings.

    U probably have apps running in the background that's causing the battery drain. Just jailbreaking an iDevice doesn't make the battery better or worse

    Actually, yes. I've noticed the same thing. Usually, even having only sent about three texts by midmorning and done Crossword on the 20-minute commute to work, I'm down under 70%. By the time I leave work at 5, I've got less than 15%. I restored the phone to get rid of the jailbreak, and my mileage on a full charge when noticeably up--as in, I ended the day above 50%.

    Out of curiosity, have you noticed that the back of your phone gets hot, even when not in use? I've reached into my pocket a couple times a day to find that the lower back of the device is noticeably hotter than the rest of the phone. Not constantly, but definitely often enough to be a pattern. It gets about the same temperature that it would get if I were playing Sim City or something intensive like that, even when there are no running processes and I haven't used it for hours. (For the record, it happens whether the phone is in my pocket or not--I thought it might be just heat from my leg so I started leaving it on my desk and it still does it.) I wonder whether something I have installed is making it think constantly, and therefore degrading battery life.

    I have biteSMS, Activator (which comes with biteSMS--I don't have any weird triggers placed with Activator), SBSettings and five icon dock installed.

    4 hours 57 minutes stand by with 46 minutes of usage. Push e-mail on, wifi on, did a little browsing on Edge/3G, Push notifications, and location services on. I am at 96%.

    I jailbroke, and did a few graphical changes (MIM, blue sms bubbles, SSH, black pop up notifications, notify, and SBSettings)

    If you are experiencing battery problems it's most likely what you are running,appsyou have installed,tweaks and so forth, alsoyou have the native backgrounder from applethat will stay running. My best advice would be do a complete back up of the phone,cydia backup,and rock if u use that also. Then restore and try again I have had the same problems but it is fixable

    I seem to be having the same battery issues with my jb iPhone(Iphone 4). I also noticed it's taking a little longer to charge now than usual. I might revert back and see if it changes.

    recent tweets from @planetbeing saying the Signal keeps running in the background and might be wise to close it down... he's looking into it apparently...

    i can say my battery life is **** after JB'ing... I haven't yet pinpointed what the cause is... But Signal might be one contributor... although I don't think it's the only thing...

    I'm not sure why all of these people are whining about their battery with the jailbreak. The jailbreak itself doesn't touch the battery. It's some app or push service they have running in the background eating battery.

    I kept it simple- jailbreak- SBSettings- Bite SMS and I have the same wonderful iP4 battery life as always.

    I tried to keep even more simple then you: SBSettings only but still my battery was 15%by 3PM. i know that its common sense that JB has no effect on the battery what so ever, but the fact are that some how it is.

    this is what makes me think that "mobile subtract" is some how related to that problem. if you recall it was updated last week to a new version purely because of the Skype problem that it created.....

    My original iPhone and iPhone 3g were both jailbroken prior to getting my iPhone 4. Used the 4 extensively prior to jailbreakme. It had the most amazing battery life. I literally was blown away.

    Then I jailbroke it. I kept it simple. I really do it to tether, use sbsettings, quickreplysms, and to maximize audio and adjust vibration patterns.

    My battery has blown since the JB. I saw 10% drops over a six hour period without use. That's after killing processes that were running in the background.

    I decided to remove some things. Same problems. Eventually, I just removed MobileSubstrate. This also removed most of the customizations I had (sbsettings, quickreply, and 5 icon dock).

    BAM...battery life back to normal.

    Yes, I miss those three things. But having an amazing battery beats it. The only thing I wish I could get is the Saurik PDF Fix....but, alas...it uses MobileSubstrate.
