I see posts in various forums from people worried about phone battery life and possibly even carrying an external battery with them on the marathon. I'm sure no one on our rD forums needs to see this, but just in case...
For me, I
hate carrying any extra weight, and it is a very rare occurrence that I don’t have plenty of battery at the end of a normal day. So my 2-cents worth:
1. I don’t have a ton of apps on my phone in the first place. If I don’t need it, I prefer not to have it there.
2. Turn off the wi-fi, particularly during the Half and the Full. If wi-fi is on, your phone is constantly trying to find wi-fi signals, which are going to be mostly other phones out on the open road parts of the course.
3. Go into your phone and see what apps are using the most battery, and start turning off tracking and notifications and automatic whatever. Instructions for an iPhone are below; Android has a similar feature. FWIW, I was using a local radio station’s app for traffic and weather and it was bringing my former Android phone to its knees. I have no clue how much tracking and keystroke logging must have been built into that app, but removing it
greatly improved that phone’s performance and battery life.
4. Moderate how much time you spend on your phone in the corrals. Having the screen lit is a big power hog.
That isn’t to say that can I do a race and then go to the end of a long day in the parks without any recharge, but I can comfortably make it through the races. Likewise, I can spend a regular day in the parks without a recharge. YMMV
For Garmin watches: Having walk/run notifications on uses a
lot more battery than with them off. My Garmin watch made it through a Thanksgiving half with no trouble with walk/run turned on, but I neglected to note how much battery was left afterwards, so I’m not sure for a Full. I can also say that by the 8 or 9 mile mark, between the cold and the vehicle traffic on the parkway, I wasn’t really noticing or abiding by the run/walk alerts; maybe the relative quiet of WDW will mean being able to stick to the pace intervals better. So if you are concerned about watch battery life, or don’t have one, see if you can glom onto a pace group, or do a walk break at the end of each song (appx 3.5 minutes if you are listening to music) as alternatives.
Good luck and see you at the races.
How to check iPhone apps battery usage:
- Open the Settings app on your iPhone.
- Scroll down and tap on Battery.
- You'll see a graph and a list of apps and services, showing their battery consumption by percentage for the last 24 hours.
- To see more detail, tap View All Battery Usage to view usage for the last 10 days or tap on individual apps for a breakdown.
- Toggle between Battery Usage (percentage) and Show Activity (time) to see screen-on vs. background usage.
