Iphone 4s performance very poor after iOS7 update

Question

Hi Guys,
I just thought i'd post my experience on my iphone 4s...
First of all the phone is approx 18 months old.
The phone was perfect until I updated to the popular IOS7 update, cough!!!!
Heres what's happening...
iPhone probs since IOS7 update
First of all the phone never missed a beat until ios7 update. Please don't insult me apple and tell me that this is a coincidence.
-Batt perc poor accuracy readings, sticks on amount for long period until reset, thereafter reads incorrect again. Last week was reading 93% but was actually flat.
-Batt can read low, phone freezes, reboots on its own & batt will then read at a higher perc.
-Phone freezing and rebooting on its own intermittently, either has to be physically switched on (from black screen) or white apple appears & it switches itself on.
-Select msgs or email - white screen appears only.
-Have to reset phone on numerous occasions due to lack of or no response.
-After reset all messages, emails, notifications etc come in all at once
-Will get bulk messages, even from same people.
-Will not open messages or email at times, poss due to signal loss while phone shows still signal bars (States switch in wifi or network)
-Loss wifi all the time, doesn't work at all now. (oddly it worked again in the apple store which left me really baffled?)
-Search for email now poor
-App Store search poor, loading poor
-Alarm clock not working at times
-Switching off on its own
-No response from screen at times and accassional delays when it does work
-Battery drain excessive, even when not being used! I have switched any hidded consumers off
-Very jaggy/not smooth in operation at times
-Opening app, settings etc take too long. An app might 'blink' i.e. Flash off then back on.
-Wifi on at access screen but switched off in settings and therefore  can not select on option
There could be a battery issue here but only since ios7 update has this all came into play. I used to really like the phone and enjoyed using it.
I was at the apple store yesterday and the guy showed me that my battery was borderline 79 -80% condition (orange).
He mentioned that there also may be software issues so I am now going to carry out a full retore from new,and post back during the week.
If a company from any technical background that deals with software, and hardware, and the the system or particular part of the network/system/hardware lays down, then you must stand by it.
I am due an update apple if you're listening, but if a battery is going to last only a year and a half or less then I very well may take my chances with another manufacturer. I just can't be bothered with hassle and the thought in my mind waiting on the phone battery failing at some time.
I understand the technology behind it all but maybe apple need to look at the consumption side of things more than the makng a stronger battery. Maybe consider a secondary system using small second battery or solar, with temperature regulation of some sort. Another approach would be to have a primary system (for calls, texts and maybe limited internet) and a secondary system (for apps etc etc) simply controlled by a type of  switch/relay/regulator i.e. if the battery drops below 25% you will not get to use secondary systems keeping your phone usable in terms of making calls, which the mobile phone was intended, remember!!!!
I called my phone network company and they said they would cover the bill for a new battery as the guy in apple store suggested would fix the powering issues.
P.S. I emailed apple about this last week, got an auto response stating we'll get back to you in 24 hours, and guess what, they didn't.

I have a similar problem.  I have an iPhone 4s that was working perfectly.  Almost immediately upon upgrading to iOS7 I noticed that the battery began to drain much quicker.  This morning when I tried to recharge the battery it would not recharge.  I followed brad805's suggestions.  When I took it to the Genius Bar they attempted to remove the battery and directly power the phone from a cable and that did not work.  The phone is now completely dead and because it is past the one year warranty period, there is little that the people at the Apple Store can do to help me. I took very good care of the phone when I owned it and there were no incidents to the phone in the time since I upgraded to iOS7.  I strongly believe that the upgrade to iOS7 is the contributing factor to this phone failure. 
Is there a mechanism to register a complaint with Apple?  I understand that phones fail from time to time but based on the posts I am seeing on the internet, I fear that there are additional instances like mine.
