So I started yesterday on a full charge, and by 2ish the phone was dead. I used it fairly heavily, but wifi was off. I don't think I made any phone calls, and didn't use gps. It was mainly messaging and using the xda app. I had changed my screen brightness to auto the night before, so thought this might have reduced the battery life.
I then left the phone off, and charged through till just before 5pm. At this stage, the phone was up to between 90-100% charge. My intention was to see if I could get through to this afternoon on this charge. Last night I made a phone call for about half an hour, and used gps for about 10 mins driving in the car. Other than that it was a bit of messaging and browsing, but not heavy use by any stretch of the imagination. I had wifi off, facebook sync every 4 hours, and screen brightness set to about 50%.
This morning I woke to less than 10% charge on the battery, so have left the phone at home charging, and I'm back to my hero...at least for the morning.
I must admit, I'm starting to get concerned, because I really don't think I'm using this phone more than my Hero, and I could easily get a day out of it (unless I was going for a long run using some kind of gps app).
What are other people's experiences? I'm surprised I'm not hearing more about this, and I'm hoping mine is just a one off!
Today, 12 hours after taking my phone off charge, I have just under 20% charge remaining. The phone is now on it's fourth cycle, and although I haven't used the phone quite as heavily as yesterday, I have still used it quite a bit and have had WiFi on the whole time. This is still not amazing battery life, but it is still much improved. It definitely illustrates that the battery may take a few charge cycles before it optimises itself.
