Hello,
I have my P7 for two weeks, everything great until 2 days ago.
I noticed the battery draining too fast. When I checked the battery stats, it shows the wifi on the whole time, as you can see in the print screen, when it was actually off.
Tried turning on and off, rebooting the phone, nothing works.
Any idea why is this happening?

I go to bed last night and battery shows 50%, don't charge it, leave unplug. Wake up this morning and still shows 50%. Notice no 3 or 4g, go to put in airplane mode and won't go. So reboot, get 4g back and battery is at 5% now. Anyone have this happen before?
Maybe the phone was frozen?
Are you stock or Rooted or what
Stock. Seemed froze but if it was why the 45% battery drain with no activity?
Actually it wasn't froze because I could open apps, just didn't have data.
I think it's a good guess that the process that was reporting 50% left was problematic. There wasn't sudden drain; it was just showing the wrong battery left until you restarted it.
Have a peculiar problem, The phone drains off faster than usual for last few days. In couple of instances it showed 40% battery and suddenly the phone got switched off. When i switch on it showed 0% battery and again got switched off. When i put on charger it was back to 40%.
Also full charged battery drained to 25% in 5 hours, earlier it used to come atleast a day. Battery also looking a bit fatty in its surface. Any pointers if this is the battery problem or any calibration issues? I use the stock kernel - 2.3.6 and this is there since few months. The problem started only few days back.
This happened to me too and it turned out it's a battery problem.
When I changed my battery, everything went back to normal.
If you know somebody who owns a similar battery, you can test it on your phone.
During the night, my Sony Xperia SP was charging. I began charging at 1:30am and i fell asleep after that. I woke up at around 8:20am and pressed the power button to turn on the screen. It did not turn on, and then i noticed the phone was turned off. I powered it on and the battery was at 100%, however i thought it was strange that the phone was turned off because i had left it on overnight. I checked my battery stats on Battery Widget Reborn (The Android battery stats, GSam and Better battery stats showed no data because it was all erased as the phone turned off) and found out that my phone had completely, after being fully charged, drained 100% of battery in just a few minutes. This is the first time it had happened, and i had bought this phone only about 2 months ago. I had not left any processes/apps running, even so, the battery should not have been draining this quickly. The drain from 100% happened from about 4:18am until 4:20am.
What would have been the cause of this battery drain?
Has this ever happened to your phone, and is this problem unique to Sony Xperia phones? I have heard that Sony phones have very bad battery optimisation and battery life.

First of all, sony phones have great battery lifes. I know that because of my experience with xperia phones (mine and friends' ones, too). Personally, I passed through an xperia tipo and now I have an sp, so they DO have great battery lifes. As for your problem, I think it's the battery stats that cause it. If you'd be able to take off the battery (youtube might have such tutorials) for at least 10-15 seconds and put it back on, it may solve the problem (taking off the battery for such a time is similar to "wipe battery stats" command in recoveries). Alternatively, you can install a recovery (e.g. c.w.m.) and wipe the battery stats. If the battery keeps draining like crazy, I'm afraid it's time you went your phone to a service center so they'll replace it with a new one.
So I've never had a problem with my battery at all. I easily got 6h of screen on time and everything was great.
Recently my Nook started to randomly shut off at around 20-30 %. It "popped" and it was off. Didn't reboot either. Like the battery was dead.
I would have to charge it again to be able to power it on.
Also the stats seemed to be off. The lockscreen sometimes told me it's fully charged and whenever I unplugged my Nook it wasn't fully charged. The battery LED also sometimes flashes green/red during charging.
I only get around 2-3 h of SOT at the moment.
I tried reflashing a couple of times (with full wipes) but the problem occured again.
So my question is: Are my battery stats messed up? Does it just stop charging at a certain point because it thinks it's fully charged but it isn't in reality?
Any ideas (on how to fix this)?

It's almost sure that you battery is degrading very fast. But its my advice to re-calibrate your battery. Set your screen brightness to max setting and leave it on until it shuts down. Now don't power it on. Leave it charging for around 2 and half hour.
Now install geekbench benchmark app and test your battery.
If you heard a pop noise, the battery probably delaminated/micro-exploded. (Li-Ion's tend to swell and fail from the heat of (over)charging.)
There's a company, newpower99.com, who has a YouTube video on replacing the battery in the HD+. The battery sold for $25 US last year, but now that our batteries are beginning to degrade, they're out of stock.
I found another site selling replacement batteries for $80. (portatronics.com)
I've noticed that my screen-on time has dropped from 6 hous to 5.5. Maybe the Nokia N1 will be available and rooted by the time I hit 3 hours.

I'm having the same issues, and reading this reminded me of trying BatteryCalibration to reset the battery since my nook HD+ stock OS is rooted.
I had this problem several times before I installed CM. Usually, it happened when there was an update available, and when the Nook started to update, it factory reset itself.
Sent from my *unrooted* ZTE Zinger using the Tapatalk app.
When I got my phone (25th of September) the battery life was great and I even had a ton of apps installed.
Recently my battery drain got worse all of the sudden. I thought this was due to a lot of apps, so I did a factory reset. This didn't help so I did it again. While it got somewhat better, it's still very bad.
With 3 hours SOT I lost 70%. I went into battery usage and it said my phone was constantly awoke and it probably shouldn't be that way.
Here's a pic of my usage https://imgur.com/a/Q3SfMm3
I'm really desperate and don't know what to do and if my phone is faulty.
Edit: I was on 4G for the majority of the time, yet it says Wi-Fi was always on, while I had it turned off.
