Increasing Battery Life on Windows Mobile using GPS and Web updates

由 一笑奈何 提交于 2019-12-08 07:02:45
问题 I have an app that runs on Windows Mobile and uses the GPS to update its location at various intervals. As expected, enabling the GPS chip uses more battery power. (no duh..) So currently my technique has been to cycle the the GPS on/off at approx. every 4 minutes to acquire the location, do something if things changed, and update its location to the web only if necessary. Otherwise, shut it off again and wait. On my one year old HTC Touch Diamond phone, with a fresh charge, leaving the

Energy efficiency in unity3d - halting app waiting for user interaction

由 北战南征 提交于 2019-12-08 04:28:25
问题 I am looking for a way to make my unity3d app sleep while waiting for user interaction (touch, mouse or keyboard event) or timer (minute-scale). The app is closer to an e-book reader than a game. The user interaction is best described as reading a non-animated wall of text 99% of the time. Sometimes there is a background sound (max 5% of time), it is enabled by interaction. Target platforms are android, ios, and webplayer. Rendering even a single texture with normal FPS can drain quite some

iphone - What consumes less battery? StartmonitoringLocationsChanges or startmonitoringforregion?

由 会有一股神秘感。 提交于 2019-12-07 14:37:19
问题 I would like you to give me your feedback on which method consumes less battery. My app will run in the background and will wake up with location changes, so I would like to use the method that consumes less battery. Any ideas on which one it is? Thanks 回答1: Neither of these choices is responsible for more or less battery consumption. In order for your app to be notified of any location update, regardless of whether it is for a region change or a significant location change, you must specify

Off screen rendering when laptop shuts screen down?

由 人盡茶涼 提交于 2019-12-06 19:43:40
问题 I have a lengthy number-crunching process which takes advantage of quite abit of OpenGL off-screen rendering. It all works well but when I leave it to work on its own while I go make a sandwich I would usually find that it crashed while I was away. I was able to determine that the crash occurs very close to the moment The laptop I'm using decides to turn off the screen to conserve energy. The crash itself is well inside the NVIDIA dlls so there is no hope to know what's going on. The obvious
