Okay, so I'm a conspiracy theorist that 9.3.5 IOS was meant to destroy 4S to force people to upgrade. A few months ago I got annoyed about the constant update messages so finally ran the update. I don't use my Iphone like others do. I think in the 5 years I've had my phone I've been in the App Store once to download Facebook app and that's it. Since *downgrading* to 9.3.5, my battery that use to work fine all the time mysteriously drains away even when it has been plugged in all day. It will go from 100% to 24% and when you check battery it will say use was 22min and stand-by was 5 hrs. Usually the only time of day I use it is to surf the Twitter web. But if I don't clear the cache out immediately after doing so, it will say Safari is using something like 93% of the power consumption. I stopped background app, refresh, wifi, uninstalled the FB app, stopped mail from auto fetching. None of this works. Even when idle whether on the charger or not, the battery will *supposedly* drain. I say *supposedly* because I suspect the battery is fine and something is causing the battery to show no power. For example, I just took my phone off the charger at 100%. 60 seconds later got the low battery symbol and had to plug it in since it isn't usable. It still has that symbol making the phone unusable. I've had it. How do I get rid of 9.3.5? NONE of these problems showed up until I installed that update. The people at Apple should be ashamed of themselves to release known bugs. I think it was purposely done to force an upgrade. Joke's on them I won't be buying another Iphone. Help please. Anybody else experiencing this. How do I de-install 9.3.5. I don't use Icloud stuff so I'm not real familiar with how all that works.
