Once a week we dip into the tips box and share some of the great reader tips that come our way. This week we’re looking at protecting your ears with automatic volume adjustment in Android, a compact way to take advantage of Windows ReadyBoost, and secure phone charging on the go.

自动调整媒体音量，以便在android设备上使用耳机

Javier写了以下小贴士，让你在换耳机的时候不至于爆耳朵：

I frequently use headphones with my Android phone while commuting on the train and sitting at my desk. It’s super annoying to have the discrepancy in volume between the phone’s speaker and the headphones be so high that it startles you and/or hurts your ears. For awhile I would just turn the media volume all the way down, then plug in the headphones, then adjust it back up… but that’s a waste of time! I found this great app, Hearing Saver, to do the work for me. You install it, run it once, and adjust the volume to your comfort level with the headphones plugged in. You can even set it to mute the ringer and notification sounds, as well as adjust the volume to a certain level when you unplug the headphones. It’s a little thing, I know, but it saves me a few minutes of fiddling a day.

很高兴找到Javier；我们非常喜欢解决烦人问题的简单应用程序。这个看起来像是解决了扬声器/耳机的差异问题。谢谢你的来信！

为windows readyboost使用计算机sd卡插槽

Tony写了以下关于从未充分利用的SD卡插槽中获得更多里程的提示：

I never use the SD card slot on my Windows 7-based laptop. I’d been experimenting with Windows ReadyBoost and I found that it actually helped out. The only problem was that I hated having a big USB drive sticking out of the side of my laptop. A few days ago it dawned on me that I never used the built in SD card reader which is really just a skinny USB drive, when you think about it. I grabbed a cheap and decent sized SD card from Amazon and now I’ve got the boost without the bulk!

笔记本电脑上的SD插槽实际上是为此而生的。对于不熟悉ReadyBoost但对笔记本电脑有兴趣的读者，请务必查看我们以前的指南，以使用SD卡和ReadyBoost来提高上网本的速度。

旅行时安全地为**充电

比尔是一位经常出差的人，他在信中写道，要让你的智能**保持充电和安全：

I fly all over the country for my job and put some serious miles on my **artphone. I need to top up the battery frequently but I’m paranoid about losing my phone and/or exposing it to security risks. Here’s my two-part strategy:

I always have a **all wall charger that accepts the battery for the phone. This way I can plug in the primary or secondary battery into the wall without having to leave the phone tethered to the outlet. Nobody is going to steal a non-descript battery plugged into an out of the way outlet at the airport… where as they would definitely steal a nice **art phone.

I also keep a power-only USB cord with me. Maybe I’m paranoid but I don’t like plugging my phone into those USB charging stati*** that are popping up around airports. Sure the port is probably just a power port with no data connection… but I’m sure we’ll here about machines that push malicious software to the **artphones attached to them at some point in the future. By using a power-only cable (the cable only has the wires for power, not for data), I never have to worry about that.

很好的小费比尔，我们特别喜欢壁式充电器的主意。只有一个电池插着，而不是整个智能**，我们会更舒服。
