Useful but a huge battery hog

About a week ago I received my first earthquake warning, a second or two before the moderate quake hit. That was impressive given that the quake epicenter was about 15 miles from my location. Not enough of a warning for me to act in time in the middle of the night, but if a bigger quake hit further away, I can see how the app can save lives or prevent serious injuries.

The bad news is that the app is an incredible battery hog. I tried configuring it to allow background updates, and my phone went from 97% charged around 11:00 PM to 51% at 8:30 AM. Checking the battery usage showed that 76% of the power was consumed by MyShake. As much as I’d like to keep background updates enabled, it’s not practical at this point.

Hi, we're so happy to hear that you received the warning and glad that you're safe! As for the battery issue, we are so sorry for the inconvenience this latest update has caused you. We are currently working on a fix for this issue and request that you turn off the location access for MyShake for the time being to conserve the battery life. We will make an announcement on Twitter (@MyShakeApp) when we come up with a permanent fix. Thank you for your patience!

Living in Mexico city we had something like this for a while . But now I live in Los Angeles California and I don't know how people in the US are gonna react when they get the warning a strong earthquake is coming because people In Mexico are already use to getting them alerts that say "Strong earthquake is coming " since they have so many strong earthquakes and an early warning on their phone and they had them for a while . So since this is gonna be new to people in the US who knows how they gonna react ! Also I think we need the Alarm. I know that they have them were they have tornadoes in the US .But in Mexico city when u get the notification on your phone the Air raid siren also goes on really loud all over the city the first time I had no idea what was happening I tought a war was happening when I heard the alarm all over the city till I saw everyone running outside and they were screaming earthquake and sure enough 30 seconds later BAM strong earthquake hit . They should have those in California not only in places were they have tornadoes so people can have time to go hide ! I saw it helps they had about 30 seconds to get outside .

This app really does work

I installed My Shake a little over a year ago. Approximately two weeks ago, a very loud voice stated “EARTHQUAKE”, then something to the effect of “TAKE COVER” (the exact words used after EARTHQUAKE escape me, but it was telling me, basically, to prepare). This jarring message repeated a few times. I immediately jumped to a safer place. Fortunately, the quake, in Tulare County, California, was far enough away that it didn’t do too much where I live. I must say though, that I am now a super fan of this app. The split second it takes to jump to a safer spot could make the difference between life and death, especially for us in California. Thank you, sincerely, to those who created and run My Shake!
