Motorola Droid :: Best ROM And Kernel For Battery And Performance
Oct 3, 2010
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.

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 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

I was just hoping for some guidelines when using SetCPU as far as profiles, performance and battery life? I know it varies by kernel and right now I am using Chevy's uLV 1Ghz kernel.

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.

I have the droid rooted running lfy 1.7. My battery life has been ok but not great. About 10-12 hours of life when I send about 3 texts one or 2 calls and an occasional download. I have also run udx 8.0, cm6, charity, and bugles .5. Udx has about 8-10 hours, cm6 has about 6-8 hours, charity has 10-12 hours and bugless has 5-7 hours. I was wondering what Roms you are using and what battery life you are getting. Please include the kernel, your speed you run at, and your usage.

I deleted all battery monitoring apps and stopped looking at the battery usage info 50 times a day. I did this over one week ago, and couldn't be happier. No more looking at that god awful percentage meter, no more watching in dismay as it drops, and drops, and drops. My battery performance has never been better now that I quite looking at it all day and my sanity has slowly begun to return.

With the standard battery how many times per week do you recharge your Galaxy S ?
1. 7-10 times (every day or several times per day).
2. 5-6 times.
3. 3-4 times.
4. 1-2 times.
5. Never you moron ... I was struck by lightning years ago and I charge everything within 10 feet of me automatically !

I just got an HTC Magic from Rogers a few days ago and I'm noticing that it's running REALLY slow. The lag is unreal when I text and the battery dies very quickly. I have TWO widgets open (calendar and Google search) and the transition from sliding screens is sluggish. I rooted my phone a few days ago. Could this be the problem? Has anyone else experienced this? I heard that Sense UI is supposed to cause problems, but I haven't heard anything regarding Cupcake.

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?

i read through most of the HS/CSMS threads and really didn't find the information i was looking for. Feature for feature both applications are pretty much even, chomp seems to have some features that handscent doesn't and vice versa, which leaves only a couple things left to compare, which is what my question is based on:In terms of looks, it is very subjective so i will just boil it down to clarity.Which UI is clearer, i.e has the higher resolution? Performance: Which one runs quicker or less sluggish?I'm also downloading the apps to see for myself but, its always great to have other user's feedback, i will post mine after i use them for about a day each, and after some users' replies

I am new to the forum, so I am not sure if anyone has posted on this previously, but I am having problems with my dorids performance. The system lags when I try to drag from window to window. There is also a lag when I try to open Handcent or even just my call log.

Hey guys, can you do me a favor and go to running services and flick up and down a few times and tell me if you ever get any lag when scrolling all the way up and down? I do every time I go into it and I just don't know if it is normal or not. I see little hickups here and there when I am scrolling but it's always noticeable in the running services screen.( I have LP set to high memory)I am wondering if I have an app slowing things down for me. My battery life hasn't been good either (4-5 hours per charge) and it seems my free memory is low. After a fresh reboot it is 97 + 124 in 34 -- other 87 in 9.I love the phone and would never give it up, but would love it more if it was a bit smoother and more battery life (like lots of others are seeming to get).

I just got my new laptop today. When I did the .sbf restore before I was on Windows Vista 32bit. I now am on Windows 7 32bit. Do I need to find new drivers or anything or everything going to work the same if I need to sbf?
I have a question about shutter lag. Is there a way to reduce the lag? I have been doing some of the suggested mods to the build.prop file and I am wondering if there is a mod we can do to reduce shutter lag when taking a pic.

I was quite frustrated earlier with my battery performance. I turned off:
- WiFi
- Bluetooth
- "Use wireless networks"
- Gmail/Email pull and Auto-sync (but leave the "Background data" on)
- "Enable GPS satellites"
- Weather update
- "Enable Always-On mobile" (but leave the "Mobile network" ticked)
- and let Twitter/Facebook to automatically update only once/twice a day.
Still the battery was draining very fast. The only thing I did not turn off is the 3G. Yesterday I decided to switch to 2G and replace the built-in SMS with Handcent SMS. To my very surprise, the battery life improves greatly. I will now do a test to see how fast it drains. I have just fully charged the unit and will update it here once I get the result.

I installed LauncherPro and loooove it. However, I noticed my battery life is even more pathetic than it was on sense. Since unplugging at 8:30, I'm down to 80% already. I even disabled live backgrounds because I thought that might be the culprit. Has anyone else found that battery performance with LauncherPro is weaker than Sense? Or am I just being sensitive?

There are a few things you can do that will help your battery life and performance...
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'
Battery
� 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 am wondering if there is actually an appreciable performance boost when overclocking the Droid CPU. Does it really improve performance, or is it more just so we can say "Hey lookee here! I OC'd mah Droid!"? Nothing wrong with the latter if thats the case, I am just wondering.
Specifically I am wondering about framerates in games. I have Angry Birds (for example) on both my Droid and my iPod Touch. It is smooth as silk on the Touch, but the framerate sucks balls on Droid. Wondering if OC'ing will do anything for that.

UPDATED UPDATE: Root is no longer required! Re-released in .apk format! Get it here: UPDATE: now ported to 2.0.1 by jinx10000 at Alldroid. Available here: To all those adventurous souls out there, there is a new 2.1 ROM available at Alldroid that was built from a newer Nexus One build than Greek's. In this ROM, there is an updated music player. While the update is not very significant, it does change it a little bit. -There are no longer buttons for songs, albums, playlists, and artist. They are now tabs and always there. -If a song is playing, a "now playing" bar is always at the bottom of the screen -When you open an album, the album art is in the background of the song list. You can see in the following screenshots: Once you get to the song playing screen, though, it is the same as before. As for overall, the new 2.1 ROM is very good. Improved performance for sure. The gallery is very quick, browser, etc. GPS works, keyboard back light is improved. LED notifications still are quirky.

I just got my Motorola Droid and installed my little accelerometer app right away. All it does is registering a SensorEventListener if the user clicks the start button. It also takes the current time in millis. Every time onSensorChanged() is called, a counter gets bumped. After the user presses the stop button, the listener is unregistered and the time taken again. Using the values from above, I get a samplerate of 9 samples/sec which is WAY too low for what I want to do. The delay of the listener is set to SENSOR_DELAY_FASTEST. The Listener is registered within the main activity and is executed on the main thread of the process (I guess).
The G1 we used before was getting samplerates from around 35 samples/ second, which is way better, but still bad. Any suggestions on why the SensorEventListener performs poorly? The system is Android 2.0. App is compiled using API-Level 5.

I think we are all victims of SE because
1) poor battery performance
2) outdated system
3) low sound quality to the point i cant use it in a crowded environment
4) all this crap for a premium price
What if this was a car or any other equipment, Shouldn't the iron heads at sony recall this product. i feel cheated by buying this phone. at the end of the day this is a premium piece of equipment brought at a premium price and not a prototype.
