Battery life is horrible after iOS 6.1.3 update

Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.

Use the wall-mount charger that came with the iPad and charge overnight. Admittedly the labeling is hard to read but, if you use a magnifier and squint your eyes, you'll see "Output 5.1V, 2.1A." The symbol between volts and amps is the symbol for DC. Do NOT use an iPhone charger. Do NOT use an iPod charger. Then, operate it normally until auto shut-down (ignore any low level alerts that may appear). An irony is that doing that test to determine the total operating time is also the exact procedure necessary to calibrate the battery level meter.

I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know whether or not a battery problem exists.

According to Apple:

Use Your iPad Regularly

For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.

I am very careful to follow all of those procedures. They work very well. This issue has just materialized after my iOS update. I am not one of those who immediately blame an update for everything, but after 2 years of very consistent performance, the last 2 updates have caused significant issues in LTE connectivity and now this one is causing battery drain like nothing that I have ever seen.

In that case, how much total operating time do you get?

Battery life on my iPad with iOS 6.1.3 is the same as before.

Have you jailbroken your iPad?

Unauthorized modification of iOS can cause security vulnerabilities, instability, shortened battery life, and other issues

Try doing a hard reboot - hold down both buttons until the apple appears.

I have found that you have to close all apps and Reset an iOS device occasionally to fix high battery drain. They claim apps are not running in the background but I suspect some process gets struck increasing the load on the processor thus draining the battery a little quicker.

Reset the device closing all apps first for the best results. From the Home screen double tap the Home button to view the multitasking bar at the bottom. Tap and hold an app at the bottom till the icons wiggle with the minus ➖ button visible. Tap the ➖ button to close all apps then tap the Home button to get back to the Home page. Press and hold the Sleep button till you see the Slide to power off message and power it off. Once powered down completely press and hold the sleep button till the Apple icon appears.

Going to try this as my ipad 3 drains iteself overnight too.

Mind you isnt this trhe same as having a flat battery and having to recharge it tpo full on the mains anyway?

Not necessarily, in my experience a run away process may not be reset unless all apps in the multitasking bar are closed first. Even sometimes if you close all apps and hold the sleep and home buttons till it restarts it comes back with all the apps still in the multitask bar and the iOS device may still be experiencing issues. I found the above process seems to work best with the proper shut down. When the iPad boots back up the multitask bar should still be clear of any apps or it didn't Reset properly.

Battery life is fine for me after upgrading to 6.1.3.

After upgrading to 6.1.3, mine ipad's battery is draining quickly too.

I found that after a full reset - ie the closing of all apps, then a shutdown and restart and my ipad is back to its usual battery consumption. yay. 🙂

How quickly is "quickly?" How much total operating time do you get from a full (overnight) charge to automatic shutdown?
