Motorola Droid X :: 100% CPU Usage - Performance - Battery Life
Nov 5, 2010
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 have asked this on the bloatware thread, and I've only seen one person mention that they have seen an improvement (BringTheRain403). I know a lot of you have removed most of the bloatware by now.
Do you see a noticeable increase in performance or battery life after removing the bloatware? By removing, I mean freezing the apk's in Titanium Backup. I don't really have a problem with this stuff being on the phone, but if it will noticeably help to remove it, then I definitely will.
Got some great help last night getting setcpu up and running and there is some difference, mostly because I'm using LWP. I just had some questions on setting it up correctly. On the main page, you have the two scroll bars (I have both set to 710 and haven't had any problems) , under that is the Scaling option, What exactly does that do, and how should it be set for the balance between performance and battery life?
Follow up question, under profiles, is there any recommended profiles I should set up? Currently I have Screen off: 528/528 on demand with priority 50 (not sure what all of this means though). Are there any others that should be established?
There are a few things you can do that will help your battery life and performance...
� Do some graphical tweaks... 1. Install Spare parts 2. Set Window animations > Fast 3. Set Transition animations > Fast 4. Set Wifi sleep policy > Never While Plugged
� Adjust the Android memory management... 1. Install Autokiller 2. Menu > Presets 3. Most people have best results with 'Moderate' but you could also try 'Optimum' 4. Menu > Settings > tick 'Apply settings on boot'
� Wipe your battery stats... 1. Allow the phone to discharge completely 2. Boot into recovery (hold Home and press On) plug the phone in if you don't have enough charge to get into recovery 3. Select Wipe > Wipe battery stats 4. Go back and Reboot 5. Leave the phone to do a complete charge (preferably over night)
� Adjust your radio settings... 1. Go to Settings > About phone > System updates > Update PRL (it's normal that the phone process will force close at this point and the radio will reboot) 2. Go to your dialer 3. Dial *#*#INFO#*#* 4. Click 'Phone information' 5. Scroll down to the first dropdown selection and set according to your preference below...
� WCDMA preferred (default) - This will automatically switch you between G/E/3G/H depending on the best signal available by constantly monitoring all signals. This uses the most battery. � WCDMA Only - If you only want to use 3G/H (3G) and do not want to use G/E (2G) select this. � GSM auto (PRL) - This is the preferred option as it will allow you to use G/E/3G/H but uses the PRL list on your phone (provided by your carrier in the PRL update) rather than constantly monitoring all frequencies thus saving your battery. This may not work with all carriers if you have difficulty getting mobile data in some areas you will have to use one of the other options. � GSM only - If you only use G/E (2G) select this (it's the same as selecting '2G only' through the settings menu). This option uses the least battery.
Upon making your selection the radio will reboot and the setting is saved, so just back out back to the dialer and you are done.
I propose that we all post our battery life graph like the one I am about to post below. This way we can look at these claims in scrutiny, and perhaps figure out why it is that some people's Evos seem to last longer than others. Here is a graph of my Evo's Battery Charge over 1 day:
Wake up at 7:30am to disconnect the charger, listen to Pandora on the car to work until I arrive at 8am. Idles until lunch time at 12pm. Use the Evo to read up on some news at lunch until 1:30pm. Listen to Pandora while working until 5pm. Drive home while listening to Pandora in the car. Battery starts giving warning indications while driving, and phone dies when I get home at 6pm. Very usual day, and matches what the battery charge graph shows. The top apps of the day are:
System Processes contains mediaserver (2.4% due to Pandora), akmd (0.3% accelerometer polling), and everything else is <0.1%. As you can see I barely used my phone during the day for anything but Pandora. So based on my data, I'd say that the normal battery life for the Evo is under 10 hours. My settings are: no 4g, no wifi, no bluetooth, yes gps, yes bckgrnd data, auto brightness, no live wallpaper, yes taskmanager (ATK, set to "safe" setting. Will probably get rid of this..), no friend stream, no flickr.
I'd love to see other people post up their Battery Usage graphs as well. The App used is "SystemPanel App / Task Manager", available for free in the market. Go into Settings and allow it to Monitor. The screenshots were made by ShootMe, also available in the market.
However, this simply has not been my experience at all, I get a couple of days out of my SGS whereas some others report only getting a day.
I just thought it would be interesting for us to post in here how much battery life we are getting for the amount of use we put the phone to.
There must be some sort of pattern.
anywhere between 10 - 30 texts per day. Several emails - sending and recieving. a few phonecalls. 30 Minutes of gaming. Twitter. Live wallpaper running. BBC News widget running and Weatherbug widget running. I also listen to some music but this varies day by day. 3G and HSPDA are left on constantly as is my wireless. GPS is turned off.
Thats my usage and i get at least a day and a half. Would be interesting to compare...
We've all heard the horror stories (I just bought my Desire and the battery lasts for about 4 hours!) and the fanboy wankery (I get at least 3 days of heavy use!) So today I unplugged my Desire at about 6am and set off for work. It's 7pmish now and here's some stuff you may like to look at. I have 3G disabled, Sync on manual, no "live" widgets (just WiFi and bluetooth) live wallpaper (nexus) and screen brightness on auto. Here's the battery status (rounded up from 25% according to Battery Info in the Testing app)
The breakdown of usage: My phone was idle for 9 hours and 45 mins: The Display was on for a mere 2hours and 46 mins With only 1.5 hours of WiFi: And 30 mins of calls: So, that'll be less than 3 hours of usage.
I'd like to know the opinions various Galaxy S users have about this phone's battery life and their usage profile. I'd appreciate if you can provide me the following information:
1/ How long does the battery charge last between charges?
2/ What is your approximate phone usage profile during a day? (Eg. 2hrs of browsing over wifi, 1 hour of browsing over 3G, 1 hour of video playback, 2 hours of audio playback/streaming while browsing etc.)
3/ Other useful information (Eg. signal conditions - poor 2G/3G coverage around my office)
Ive used Cm6 and had some homescreen lag issues so i tried liquid frozen yogurt 1.6 and i love it. i ran the slayher kernel and it seemed to be doing just fine. it is snappy and battery life is better than CM6. I also tried simply stunning v4.8. I really like SS a lottt but with the chevy kernel my battery life was absolutly terrible. I don't know why that was so i switched back to Liquid froyo 1.6 and my battery life is a lot better now. Does anyone know about UD extreme 8? ive heard good things but i just wanted to know a little bit more about it. So basically my question is what do you guys think the best ROM and kernels are for performance and battery.
I see some people in the forums bragging about how great their batteries are and i am jealous I took mine of the charger at 7:00 this morning and at 3:00 my phone was already down to 40 percent. My question for the users that also seem to have poor battery life is, once your phone reaches 40% does a reboot give you more battery life? Every time my phone reaches 40% a reboot brings mine back up to 60%. This happens every time so it is not a coincidence or a onetime thing. I am curios if the reporting is off because it is almost 5:00 and i just did a reboot and now I have 60% left. I can live with 40% usage from 7:00 to 5:00 but I can't live with 60% usage from 7:00 to 3:00
Does anyone else find that their battery does best at like 60%-70% charged and when it gets below 40 it moves a lot quicker? Also I've done 3 full drain and full recharges so far and my battery has improved sloightly each time, do you reccomend I do it again or is that just bad for the battery?
- I'm running the "Battery Left" widget and I have it displaying "estimated percentage left", "system percentage", and "estimated time left until dead".
- I listen to A LOT of Slacker Radio.
- I was previously getting about 19+ hours out of a fully charged battery. 2-3 days ago I started having issues with the widget (I think it may have started when I installed an update to the widget) so I recalibrated it to no avail. Then I uninstalled it and reinstalled it. Within a few hours it claimed that it was getting accurate readings (when I first installed the widget weeks ago, it took days to get accurate) and now says that I should be getting 9 hours out of a fully charged battery. I know that can't be right so I'll see how the widget adjusts itself over the next few days, but, any thoughts? (I know a lot of you guys use the same widget and know how it works...)
- Also, In the first two hours of my phone being unplugged this morning, it went from 100% to 70%. I did run Slacker for about an hour and a half of that time, but could it really drain the battery that much that quickly? And I noticed that when I close Slacker, if I go into phone settings, applications, running services - there's still a Slacker update thing running in there. Could that be draining the battery too, even if it's only checking for updates?
- I really don't run a lot of stuff on this phone. I keep wifi and gps turned off. I use bluetooth only a few hours each night. Minimal web browsing. Although, my POP email gets checked every 5 mins (but I just changed it to every 10) and I do use gchat and text a decent amount, but I'd say overall, it's "light" use (except for Slacker which could be a huge drain, right?)
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
I just got my droid x about 2 days ago, and I've gone through about 2 full cycles. So far I haven't been able to squeeze more than 6 hrs of use on it, so I installed spare parts to see if the GPS bug was affecting it.
Going through some usage information, I found that the "Android System" sensor usage was huge! Since 1hr 29min unplugged the Sensor has been on for 1hr 36min...weird.
Checking the total time since boot the sensor has been on 19 hrs. I have autobrightness turned off and I haven't come across any other posts that explain what uses the sensor.
The update had to have helped. Never got battery life like this before. I'm at 14 hours 36 minutes and 60%! I do power off the phone at night when I go to bed and plug it in. voice calls 40% display 27% phone idle 10% cell standby 9% browser 6% android system 4% android os 2% backgrounds 2% I have no task killer. GPS and wifi off. Screen brightness on 4%. Twice today I turned off News Feeds and Skype. But they keep turning back on.
I have had my DX since it came out in July. I work in a Rural area in a Cinderblock and brick building so my reception when I am at work sucks to say the least which I know kills my battery, but I have tweaked it enough that I get about 18 hours of battery life during a normal day. The problem I have noticed is that about once a week my battery goes from 80% to 10% in about 20 minutes and the back of the phone gets warm. If I pull the battery for about 10 min. It works fine for another week or so. Any one else seeing something like this?
I was all for going with Sprint from ATT to get the Evo, but with all the negative reviews of the battery life, I'm thinking about going the verizon Motorola Droid route. As you can tell the battery issue is a huge deal for me, is the Droid's battery life better than the Evo's?
