An increasing number of Nokia Lumia 920 owners are reporting devices overheating, coupled with fast battery-drain.
The fault - if it's a fault - appears to be software-related and also seems to be intermittent.
Users of Nokia's new flagship Windows Phone 8 device say they can experience unexpectedly fast battery drain - like 100% to 10% in just four hours - which seems to link to devices getting very warm to the touch...not burning hot, but noticeably hot.
Here's a typical story from Christina Warren of Mashable who's writing a daily diary of using a new Lumia 920:
There are similar reports in Nokia and Windows Phone forums, including Windows Phone Central.On my first day with the 920, I noticed that the battery life wasn’t great and that the phone was hot to the touch. I didn’t dwell on this because I was doing a lot with the phone — setting it up, downloading apps, etc. After a full battery cycle, the problem seemed to disappear.In fact, on day two with the phone, I really didn’t have any noticeable issues with the phone. So far, so good!Yesterday, that changed. I left my office around 4:15 to go to an event — the phone was at 100%. By the time I got to the event’s location — maybe 20 minutes later, I’d probably lost 10 or 15% of my battery. Moreover, the phone was very hot to the touch.At the event, I sent a few tweets, took a few photos and browsed some websites. I noticed the phone was getting increasingly warm and that the battery life was dropping quickly. I made sure my background tasks were off (only weather could still run in the background), NFC was turned off, and I didn’t have geotagging on the camera.By 6 p.m., my phone was down to 55%, dropping at least 40% in just 90 minutes.I sent the following tweet with a screenshot of my battery at 6:24 p.m.While I was able to make it to my other events, I was afraid to use the phone. Even without being used — the phone was almost dead (4% battery) by 10:30 p.m.
There are always teething troubles for new devices, but this one seems widespread.
Some owners say resetting the phone cures the issue...but it's only temporary and the battery drain/overheating cam return.
It's at the point now when Microsoft and Nokia have got to say something. If it's software related, they need to get out a fix quickly in the form of an over-the-air Windows Phone 8 update.
If it's faulty hardware...well, RIP Nokia and Windows Phone.
