HTC Droid Eris :: Google Navigator - Battery Usage Tip
May 16, 2010
I did some testing with the Navigator yesterday and I have to say it's absolutely awesome. I'm not sure if anyone has posted this, couldn't find any mention of it, but I want to share my battery usage experience with it as well as some other cool things I noticed.
Very cool battery saver:
I used it for a 15-minute drive, keeping it only in the Notification Bar. When you are in the Navigation app, you can press the Home softkey to go back to your home screen. This keeps Navigator working in the background, but it is not drawing the maps and using the screen. You can press the Power button to put your phone to sleep, and the voice actually still talks to you and tells you when to turn. And even better, I started this trip with 76% battery and ended with 76% battery.
Now, the not-so-cool.
I used it for a 30-minute drive, keeping the screen on and letting it show me the map the entire way. I started the drive with 54% battery ended with 34% battery. So definitely keep it on the charger if you are using it for a long drive. But another awesome thing I noticed. I made a phone call toward the end of my destination, just to see what would happen. I used the Home key to back out of the Navigator (but keeping it in the background, as I said above), then made my call as normal. The Navigator still gave me directions while I was on the phone. It came through the earpiece now, so the other person doesn't hear it. How freaking cool is that?
My Eris, just updated on Monday for the lock up from sleep Anyway, I am a low user of the phone and keep, wifi, Mobile data off unless I am using it I have noticed the last 2 days the battery life is improved. yesterday, phone on at 6am off at 11pm, 65% left, no data used, few Txt messages and about 45 min of phone calls Today so far, on at 6am, WIFI, Mobile data off, one 6min call and one txt, at 9am, still 100% battery. turned Mobile Data on at 9am now it is 11:50am and battery is still 100% my on time is 5:45, awake time is 8 min (2%) this is typical for me. I don't have email set to push, I refresh when I want it. I also use Advanced Task Manager. So maybe the issue that was fixed was also causing a battery drain and is fixed now?
I am running the 0.3 rom.. and there is no battery usage under about phone.. its there on the droid am i missing something? Also to make it more stange when you get down to 15% it gives my a low battery warning i can either say yes or view battery usage.. but cant seem to find it anywhere in the menus.
I manually updated my Eris the other night and I must say I am happy with the update, it has really helped with my battery. What I have done is installed Battery Indicator by Darshan Computing. This puts a battery percentage indicator in the notifications area. I have set the built in timer for an hour and when it goes off I make a note of the battery in form of a percentage. Here is what I have so far.
Hour/Percentage of Battery Remaining 1/98 2/85 3/82 4/80 5/77 6-70
Searched for a solution to this, but was unsuccessful.I got the OTA on Saturday and noticed that I had a program called "Navigator" and a program called "Navigation".Navigation had a blue arrow icon. Yesterday I had to do a factory reset and now I am unable to find the "Navigation" shortcut.
Am I doing something wrong? If I am using Google Maps/Navigator - happily following along as my car wends it's way down the street and I have to exit to say, answer a phone call, look at another app. when I go back into Navigator my destination info is gone. I have to re-enter my destination.
Just got back from a 500 mile road trip. I was using the Droid X car dock and Google Navigator. I noticed that about after 15 minutes the phone would no longer be actively charging (the lightning bolt icon in the battery was not displaying). Within two hours the battery was depleted. I know Navigator is still in beta.
Maps vs. Navigator vs. Navigation. didn't find anything that compared the 3 stock options that the 2.1 OTA gave us. So far I have been using Navigation (the blue arrow icon) and i think it works extremely well, it give voice directions while the program runs in the background and your phone is "sleeping" so thats a big plus for me. I didn't see a voice option on Maps, or Navigator but i may be missing something. Navigator looks cool, but doesnt seem to have any bells and whistles that I need. My wife uses Maps and she is happy with what it does. What are your experiences with these 3 options?
A client of mine also has an Eris and I was helping her get her navigation system set up and teach her how to use it. I wanted to put the google navigator icon (the blue arrow) on her home screen but could not find it anywhere in her apps. I did find the google navigation (map icon) app and set that up for her. So, my questions are: What is the difference between the two? How come I couldn't find the navigator app on her phone (on mine, it's under "programs")?
When i check my battery usage its saying that Maps has been using 90 percent of the battery. Its been doing this the last couple days even with me charging it at night. I didnt use maps at all today and its not showing up in my app manager as running, or a newly downloaded task killer. Its not really affecting my battery life which is weird and doesnt make sense. So i was just wondering if anyone else was having this problem(sorta more like inconvienence)?
Google Maps is taking up all of my battery life after using navigation. I've tried backing out instead of using home when on Maps. I always use 'Exit Navigation' when closing Navigation. I've tried killing the task. The only thing that has worked is restarting the phone.
Thought it would be a prudent thread to list all of the battery killing apps and processes (ie don't shut down right)that have been found in 2.1. The one that I found, the hard way after 3 straight days of only getting 10 hours of battery life, is the Google Talk service. I accidentally opened it and System Panel didn't kill it. I only found it by looking at Battery Uses>Running Services.
So, like many of you, my phone would occasionally get hot, and the battery would just zoom down to nothing. Usually this was just intermittent, and a restart would cure it.On June 10, it was happening, and persisted despite restarts, battery pulls, etc. I finally found that the problem was google trying to sync contacts. It was having some problem and cycling forever. When I unchecked the google contacts sync in the accounts preference panel, problem stopped. My battery life has never been better. Routinely getting 18-20 hrs or more.BUT I want to sync my google contacts! Every time I trial re-checking that box, it cycles and cycles, every few seconds giving a little error at the bottome of the screen (in prefs) "Sync is currently experiencing problems. It will be back shortly".I have 700-something contacts (Only 250 real "My Contacts" but another 500 or so auto-created contacts from gmail use.Presumably one of those entries has some corruption, but I can't figure out which, and I don't want to potentially lose all the contacts.I have seen that for some people this was fixed by factory reset and resync, but then the problem came back a few weeks later.
When hitting battery usage, would the LWP show up under display? I loaded in a new LWP from the market and checked battery usage and display was off the chart % wise compared to my normal use. And that was with some pretty decent phone activity. I disabled the LWP to check, but does anyone know if it will show here? Or anywhere?
Is there an app that shows what is using the battery? On my Droid it would actually show what was using the battery: Display, slacker, dolphin, live wallpapers, etc. On my X when I check battery usage the only thing it ever says is: display, cell standby, phone idle. It never shows live wallpaper, slacker, or anything else I run. I am wondering how much battery these other apps are using, particularly the live wallpaper. Any suggestions for a 3rd party app I can run for a couple days to see what is really using my battery.
So I just switched to DroidMod 1.0 from SholesMod 2.0.5. Now when I check my battery usage it only shows Voice Calls, Display, Cell Standby, and Phone Idle, and thats it! It doesn't display anything else like it used to. Does anyone know why?
ps I wasn't sure whether to put it in the Root section or not, Mods feel free to move
My X recently (within the last week) started having extremely poor battery performance under the same usage conditions as the previous week (K-9 syncs every 15 min, maybe 2 texts per hour, 2-3 emails per hour, maybe 5 total minutes of phone use). After 4 hours, the battery would be at 20-30%
To make matters worse, most functions were extremely slow to respond (contact loading, test message loading, recent calls, bookmarks, any scrolling was choppy, etc.) The delay when trying the most basic things (opening the browser, making a call) was getting unbearable.
I started backtracking the changes in the last week. Although I started tinkering with Google's App Inventor over three weeks ago, that's where I focused. I uninstalled all App Inventor programs, including the Eyes-Free Text to Speech engine. This engine was recommended by Google to do things like read text messages in the Apps you create.
Still no luck.
I decided to investigate the battery use a little more. In Battery Manager, I found that "Android System" was using about 70% of my battery. I was typically used to seeing things like "display" at the top.
I have an app called Android System Info. This showed my CPU usage pegged at 100% (even after a reboot). It never got lower than 99%. The biggest CPU hog was "Android System" at 75-80%, consistently.
This App has a tab to view the log, and I noticed several recurring error messages in the log. They were occurring at the rate of about 180 times per second! The error? "Invalid TTS Engine" Well, the TTS is controlled by the "Android System". The "Android System" was constantly trying to load the uninstalled TTS engine.
I went into "Settings...Voice input and output", and, although the Eyes Free TTS engine wasn't available, the default TTS was not set. I checked the box to have the native TTS as the default, and checked the box for "Always use my settings".
Everything immediately went back to normal. CPU usage is now around 10-20%, and "Display" is back at the top of my battery hogging functions.
Battery life is back to over 10 hours, and the delays are gone.
I consider that my "About Phone ->battery Use" is not really accurate in my case. Can you advice me regarding another android battery usage monitor application ? I am interested in seeing the exact consumption (in percentage) of each service/application.
I have a Droid Eris running OTA 2.1. I just tried using Google Navigator for the first time this morning. When I ran it it led me to install the text to speech app. Unfortunately, I had my SD card mounted (for music in my car) at the time and the install failed. I dropped out, un-mounted the card, manually installed the app, and re-started Google Nav. I have no sound in it at all now. It is not muted, and the nav volume is at max. I have heard it work on my wife's phone. The nav software was my main reason for getting an Android phone. Does anyone have any suggestions or am I going to have to factory reset?
I don't keep up that much with the latest and greatest for my Ally but this morning I saw a system update notice and decided to go ahead and update. It seemed to go smooth enough but as the post title suggests my Google Navigation crashes back to the boot screen whenever I try and use the app.
