I don't know what the hell your talking about? I lose 1% after about 8hrs of sitting idle!
I'm not sure what is eating mine. Some days I get normal usage but yesterday I went from 60% to totally flat in under 2 hours...with no use!!
I've not installed anything new, just suddenly I have huge battery drain..
I will have my phone charged to 100% when I go to sleep and when I wake up its still at 100%, that's 8 hours.
What happens if you leave your phone on overnight?![]()
And conversely I have five iPhones jailbroken in my family with evasi0n 1.2, all with battery life consistent to what they were beforehand (less than 1% battery loss per hour when idle), and lasting all day when actively used. (and when a jailbreak *doesn't* work properly for my devices, I speak up like anyone else).
Yet I never make blanket statements about the performance of any hardware, software, or networking product, as there are multiple variables in why something might work well or work poorly for an individual. Its all about taking steps to diagnose the issue for that specifc configuration.
Done with this debate -- total troll.
Instead of we all arguing with each other why dont we make a list of the most battery drainer tweaks or cydia apps?
First time post. Joined forums just so I could hopefully learn something about this battery drain issue.
I have JB'd and restored my phone 3 times in effort to isolate the root cause of my 4S battery drain.
Last iteration:
1. DFU restore as new phone. No Apple personal settings were restored (yet).
2. JB'd with 6.1.1 using evaisi0n 1.3 from Mac running OS X 10.8.2
3. Light load of Cydia apps:
-Activator
-Auxo
-Music Controls Pro 6+ (like this app)
-MyWi 6 (one of the main reasons for the JB)
-IntelliScreenX
4. Synched contacts from iTunes
5. Synched a couple of key apps from App Store
-mSecure
-Dropbox
-Accuweather
-NPR News
-Digg
-Pandora
-Spotify
Result: MAJOR battery drain. Before unplugging from car charger this moring, I did a re-start, turned of WiFi, and disabled location services. Very light phone use (a couple of short calls and texts, calculator). By lunchtime 5.5 hours later, the battery was down to 40%. Uninstalled IntelliScreenX. 3 hours later the battery was at 20% after only using the calculator a couple of times.
After JB'ing, I've noticed that the 4S is always unusually warm to almost hot. I'm not sure what processes are running that would cause this (I have been closing all my background apps), but it seems logical that whatever it is, this is where the battery is using itself up.
Really bummed about this. I have no other choice but to restore back to stock iPhone. I really liked the flexibility and functionality of the JB'd 4S. I hope the developers can find a common solution to this.
I hear folks here loudly defending the Jailbreak from being the root cause of the battery problem, I get that, but it is definitely systemic to all phones with this problem.:
I noticed a slight (very slight) drain after installing zephyr. But before that install (with only tetherme and NCSettings installed) battery life was excellent (same, if not better than before jailbreak).
After zephyr I noticed it draining a little faster, but it could be something else like cydia running so much.
It's back to normal after one charge. Roughly normal. I'll keep an eye on it.
There is one thing that is certainly abnormal after jailbreak:
I noticed that resprings change the battery percentage. Before a respring, it showed 97%. After the respring, it showed 100%.
Don't know what it means, but definitely never seen that before jailbreak as there were no resprings back then.
I blame Bush.
I have a boat load of tweaks and my battery seems as good as it was before the jailbreak.
