Leaving wi-fi on regularly
As JamesRyan mentioned, leaving WiFi attached and also non-active usages much less battery than if it needs to maintain looking for an AP.
I make use of a HTC Desire and also originally had my WiFi set to rest after 15min, yet after that became aware that every single time I opened my phone it would certainly wake the WiFi, and also subsequently it would certainly start looking for an AP. After that, I set WiFi to never ever switch off - this in fact caused even more battery power left at the end of the day (despite having the periodic sync of my accounts - e-mail, twitter etc).
This has actually been my experience with HTC's Evo :
WiFi makes use of much less power contrasted to 3G when proactively downloading/uploading huge quantities of information. Also when doing a great deal of surfing. Nonetheless, unlike 3G, the WiFi radio never ever goes to rest. So when you aren't proactively downloading and install information, it's ideal to transform it off. This differs GPS and also Bluetooth where if they aren't being made use of, they do not make use of much power in all.
Turning off anything that isn't in operation will usually increase battery life. Additionally bear in mind that the largest drainpipe on the battery is usually the display screen. Establishing your illumination to the most affordable degree (or at the very least vehicle ) can do a whole lot to conserve your battery life. Additionally, if you commonly connect to WiFi in the house, yet do not have accessibility at your job, there are applications that can instantly switch off the WiFi radio (to name a few points ) in the early morning, after that transform it back on in the late afternoon/early night. I make use of Advanced Volume Mode Scheduler to do this.
