I was having issues with the battery but for me it's improving day by day. I moved around my desktop widgets a bit. Removed stuff I didn't really need like the AP News updates.

Since then the battery has been pretty good. I use it quite a lot. Lasts me the day at least. Although I will be getting a spare battery just in case.

I'm not sure what others are on about completely draining the battery will stop the phone from working. It isn't true. My battery has drained several times to the point where pressing the power button doesn't do anything. A couple or so hours later when I do plug it in to the charger, it starts right back up without any issues.

I'm not really that bothered about going round the world in doing xyz to ensure the battery life remains good for more recharge cycles. A new battery is about £26. Hardly much when compared to the cost of the phone for £500. I prefer to use and charge the device how I like it tbh.
