After updating to ios 7.1 my iPhone 5s battery *****. It takes longer to charge and shorter to finish.

Question

3 months back I upgraded from iPhone 4s to 5s and realised 4s is a much better phone. It gave me longer battery life of around 8.30 hrs of usage on 2g and 7 hrs on 3G but 5s was giving me only 7 hours of usage on 2g and 5 hours on 3g but since I've updated it to ios 7.1 my battery ***** even more. It takes longer to charge and shorter to drain. Now I get only 4 hours usage on 2g and somewhat 3hrs roughly on 3G and it takes around 3 hours to charge where awe it used to take only 100 minutes perfectly. I don't know what's wrong with apple. I was a huge apple fan when I had my 4s but now I'm disappointed. But worst thing comes last night, I usually lose around 10% due to my network's pop up messages overnight but last night i lost 37%. When I got up and checked usage it shows me 6 hrs 30 minutes usage but I haven't used my phone since I was sleeping. Hope a new update releases soon to patch this but till that some advices on saving battery would be appreciated, thank you.

Please be more specific. What have you tried already? Please follow the below steps as described also in another topic by Nathan.
1. Hard reset hold both buttons until Apple logo appears.
2. Restore from an iTunes sync and backup.  This made a difference for a lot of peopel, battery life got much better.
3. Limit push notifications (apps and e-mail accounts - set e.g. e-mail to fetch once an hour) to those you really need.
4. Limit location services to those you really need, and watch to see if the indicator comes up.
5. Get the app System Activity Monitor to look for a runaway process that is using a lot of CPU.
6. Suggestion by others to reset all settings.
7. Suggestion by others that iCloud may be involved, and to try to turn off some iCloud settings.
8. Limit or turn off 'background app refresh'.
9. Add apps back in carefully to identify an offending app that is causing CPU or network activity that kills battery life.
10 Also make sure that e-mail is fetched (e.g. every hour) or set to manual instead of pushed.
11 Do you have a good carrier reception? Have you tried to manual set your carrier within your iPhone instead of the 'automatic'?
12 Have you checked if the timezone is set to manual instead of automatic and see if this makes a difference in battery use?
In my case it was a bug with an app that caused the battery drain. I also noticed that the use and stand-by time were exactly the same which is ofcourse not correct. This was all caused by this app which was using GPS tracking all the time. Unfortunately an app such as System Activity Monitor did not indicate that in my case but someone posted this solution on a Dutch forum that the previous version of the app 'Scoupy' had a bug and caused this battery drain.
If you haven't tried every single one of these, please do not post that battery life is terrible.
