iPhone 4S - iOS 5.1.1 (JB) - Insane Battery Drain problem

[Fozzy]

Hi everyone,

I am running a jailbroken iPhone 4s on 5.1.1

In normal use, even just on the springboard (with Autolock off) it will consistently drop 1% per 1-2 minutes. It's quite ridiculous. It hasn't just happened on this iPhone but also my iPhone 3GS which was running on 4.3.5 (with almost the same list of tweaks) had the same problem with battery draining. At this point I have to charge 2x a day if I am using my iPhone normally during the day.

Ofcourse I have taken most pre-cautions of lowering brightness, clearing backgrounded applications, but none of this seems to have any affect at all.

The tweaks I am running are:

Activator
Airplane SBSettings
AppSync for iOS 5.0+
AskToSend
Autolock SBSettings
BigBoss Icon Set
biteSMS
CallBar
Cydia Installer
Cydia Translations
Default HD SBSettings
Firewall iP
Insomnia
Insomnia Toggle
iProtect
Mobile Substrate
QuickDo
Remove Background SBSettings Toggle
ResetAllKiller
Rocky Racoon 5.1.1
SBSettings
sbsettingstoggles
Serious SBSettings HD
Snappy5
Source GUI
SpringBoard Access
Springflash
Springflash SBSettings Toggle
Substrate Safe Mode
Winterboard

For purposes of time, I only wrote up the 'Simple' list and not 'Expert' list.

I guess my question is, does anyone have any idea what could be causing the insane battery drain? I'm a bit out of the loop on what are good/bad tweaks and what might be problematic or known to be causing battery drain. So any advice or information would be appreciated greatly.

Thanks everyone!

Did you try going into safe mode and seeing if your battery still drains?

[Fozzy]

73ullet thank you for your reply.

Yes I have tried this. It slows the drain down quite a bit in comparison, so I'm assuming it is one of the tweaks being the culprit.

Any thoughts?

I'm not exactly sure as I've never owned a 4S but the only thing I see is maybe insomnia turns on when your phone is off? Maybe it causes the drain. Try disabling a few and see if it stops the drain, you know like leave a few on only, see results then so on.

Tried that a few times actually, short of just leaving things like SBSettings only on there. Perhaps I need to do it diagnostically from a fresh restore, jailbreak, then add tweak, test battery life, add tweak. etc.

Thanks for the ideas though.

I have a 4S running 5.1.1 and I found that CallBar killed my battery very fast. I found it by uninstalling each Cydia app until I got to CallBar and I noticed Call Bar was the culprit. My battery is pretty good now.

same here, if you find a solution, update here again please.

my advice ? disable Siri

tried disabling it but didn't really notice anything significant. I might have to go all diagnostic on it and disable things one by one like you said, or try disabling things slowly through mobile substrates.

What Notifications do you nave enabled, and are all you apps enabled for location services beacause these can dramatically drain your battery.

calendar, skype, reminders, mail, phone, messages, line, weather widget, facebook messenger, instagram.

The location services is pretty much just Siri and Maps and a GPS app, but by default I have location turned off.

Ok so nothing really that points to an issue, not even any of the cydia tweaks you have should cause battery drain as i have most of these installed.

I know you said by default location services is switched off, but you dont use 'Find My iPhone' do you ? I noticed by disabaling this feature really helps.

Aslo one other thing is i would let your phone battery run right down to 1% before charging, and make sure it charges to 100% i found by charging only a little at a time (i.e 20% > 80%) seemed to have a weird affect on the battery life too.

Not sure if anyone else has noticed this.

I haven't actually setup the 'Find my iphone' thing yet.

Thanks for the advice, i'll give that a try and just run it flat tommorow or something then letting it re-charge while turned off for a few hours.

Will update if anything else comes to mind!
