The Battery might not be calibrated correctly. How long has this been happening? How old is the pb? Do you still have a warranty. What charger are you using - the included one?
Due to the pb's odd charging circuitry, some folks are reluctant to force it to Zero to calibrate the battery. SUPPOSEDLY, you charge the battery fully (81 in your case), then force it down to Zero when it goes OFF by itself, fully recharge and run it down again. When my first pb had discharge problems (too much loss in standby), BB had me follow that procedure. I had no problems recharging it either time. I turned the screen light up fully (uses a lot of power) and ran a video and some battery chewing game.
Others might have different advice, so let's see what else is suggested.
Suggest you get Battery Guru which is $1.99 in BB App World(USA). If you prefer to try a free app Battery Alerts (free version) has five stars and may be useful to you. Battery Watch may also be useful and there are several others.
Per cent charge is a calculated values using voltage measurements and other measurements which are read by a program which calculates per cent charge. As F2 has noted this calculation. often requires calibration. The most important number is the battery voltage which is best measured at a time of low usage. A battery charge reading of 81% would probably correspond to less than 4.0 volts where full charge would be 4.17+- volts
The Pb was previously owned as I purchased on ebay but isn't very old. I'm using the original blackberry wall charger.
I will do what you suggested and let it run down to zero then charge fully.
I'll post again when I've down that
Good luck. The suggestion is to run it down till it turns itself off.
You could still try calling them in the event the previous owner did not start the warranty period.
The PB has a one year warranty to the original purchaser. It also has 90 free Tech support. I do not know how Rim deals with "quasi-tech support v. warranty"

I'd avoid doing that. Many have run into significant problems letting their PB's battery run down.
I've often wondered why some people can get away with letting their PlayBook battery run down until it shuts off & others can't. I never let mine get any lower than 20% just in case - wouldn't know what to do without my PlayBook....but sadly I know one of these days I'm going to have to figure it out.
I'm currently letting it die by itself then will recharge but I seem to have run into something else...
I have noticed that in the file manager there's a whole bunch of random pictures that I have nothing to do with. Pictures like app icons and stuff, there's LOADS of them, is there any way to delete them without doing it one by one on the device.. I can't seem to find them searching for them on my cimouter?

Sounds like what Kayak loads in or perhaps some other Android port. Use Ghost Commander, which is free in BB world, to find the folder in which they are stored and delete that folder.

There's no problem letting it run past the warning til it shuts off completely. My wife continually does it whilst browsing, then it's "Oh it's gone off". That function turns off wifi and powers right off. But you need to charge it up straight away.
The problem IMHO is when you get to the warning then put it on standby overnight or let it power off then leave it. It runs or leaks down way past the safe point.
So this morning it stayed on 0% for a while but eventually powered off, I plugged it in using the wall charger and left it until 10 minutes ago.. Still only at 81% battery.

The suggestion from Rim "back then" was to cycle it a second time. Fully down again then fill it up.
Do you have Battery Guru. I don't know if you want to invest in it. It shows additional data and can export to a spreadsheet.
What battery voltage is shown when the battery is at 81% and when it shuts off? As F2 has said Battery Guru will give you this data. Or there are free Android ports available in BB world which will give some information.
