I'm a newbie to this forum (even though I've been registered for quite a while), so please bear with me.
First, let me explain that I've had dozens of Android handsets, as well as iPhones and various WP7/WP8 handsets too, so I don't consider myself to be a novice when it comes to battery saving etc. (anyone like me who had a HTC HD7 or HTC Desire HD will be well versed in how to save battery life!).
I've recently bought a Sony Xperia U (purchased 10th Jan 2013). I charged it up to 100% yesterday, and within approximately 30 minutes of removing the charger, the battery level dropped to 99,98,97, and all the way down to about 89%. Funnily enough though, once it got down to about 85%, the battery seemed to stabilise somewhat, and the power drain became more normal, leaving me with about 55% after around 6.5hours of use (which, considering I was constantly playing with the phone, wasn't too bad).
I charged the phone up again last night. I put it on charge at around 9.30pm and took it off at 6.15am.
First, when I tried to unlock the phone, the screen didn't come on. I ended up having to remove the battery and re-insert it.
Then, when the phone powered back on, it only had 95% battery (even though it had been taken off charge literally 2 minutes beforehand).
Then, the phone told me that the SIM card had been removed and re-inserted, so it switched itself off and restarted.
What the hell is going on? Is the phone REALLY this glitchy? Does the battery improve over time or am I stuck with it as it is?

Please help - My phone is still within the 7 day return period, so I'm seriously thinking about taking it back to the store.
Thanks in advance
