I keep waking up to slurping sounds… And today finally figured out where they came from.
The Nexus 7 is sucking the battery dry in less than a day. I’ve had it for almost a week now and have been using it a fair bit ofcourse. But typically no more than 2-3 hours a day. About half that time was spent browsing menu’s trying out options. Setting background images and throwing widgets around. The other half involved streaming movies and tv shows via Wifi. I realize this is taking a lot of power. But the promised 9 hours battery life to watch movies in HD or 10 hours web browsing? Not even close.
Maybe 4 hours of video, this is h264 compressed video in 720p coming in at a maximum of 3mbit/sec. Sound is usually stereo or 5.1. All AAC or AC3 encoded. I stream this via Plex Media Server. So the actual video decoding is done on the server and not by the Nexus 7. I see a same draining effect when I’m on Youtube. 4-5 hours and Android tells me that it will power down.
Even when just letting it lie around doing nothing, screen off for most of the day, when I pick it up to go to bed and watch a movie i lost around 10-20% of battery sometimes. By just being on my desk. Doing nothing.
Am I doing something wrong here? Or is Android and it’s multitasking just being weird? I’m not sure. Perhaps it’s the charger… Or lack of it. Since I had the Nexus shipped to me from the UK it came with a UK charger. I can’t find a compatible plug for it that suits my house. However, iPad chargers have exactly the same specs so I use that one instead. It charges just fine I think. Electrics is electrics after all.
