Incredible 2 and CPU Usage

This is my first post here!
So it looks like I may be having a problem with CPU usage and battery drain. My Incredible 2 was fine until this morning when a market update kicked in and started running the whole phone slow, and ate the battery life to 50% within a matter of 2 hours.
I'm not sure where to start with this phone - because I haven't found an app which can give me the list of running processes which are taking the most CPU resources so I can figure out what to kill (or what to remove). Can anyone recommend some tools?

settings>applications>running services. Elixir is a good app also to show you running services. You don't want to be killing apps a lot or often though, just battery draining or memory hogging ones.

Just an fyi...the recent Pandora update to version 1.5.9 to a performance hit on both of my DInc2's. Since uninstalling, performance is back to normal.

Ok - that's good info. The thing is, I never opened Pandora or played it, but I did have a widget on one of my panels (it was never active, either). I uninstalled it, but I can't tell if I'm back to normal yet . . .

By far the best app for this is called watchdog. Amazon had it as its free app of the day a few days ago. all it does is notify you wwhen an app is using more CPU % than it should. It's not a task killer. There's a lite version as well as a full one. I highly suggest it.
And by the way, welcome to XDA!

It looks like the process for HTC Mail is causing CPU drainage (I think it was com.htc.mail or something - I can't get it to reappear). I Force Stopped this process and amazingly, everything starts running smoother - panes switch like silk, scrolling is smooth, etc. This also appears to be what was draining the battery, as it quickly rose to the highest percentage of what was eating it.
The process gets restarted at some point because I've had to Force Stop it a few times already but at least it stays off for quite some time. So far, it's been about half a day since I had to kill it last.
The funny thing is - I can force stop it and still use all my HTC mail functions properly and they run quicker than ever.

Improve battery life?

I'm down to 36% at the end of the day and all I do is listen to music with little gaming.
Any ideas?

Already off. Sometimes I use airplane mode.

I'm down to 0% after 4 hours with an extended battery... lucky.

What ROM/kernel are you using? Also, try out the app BetterBatteryStats to see what's draining all that power.
Streaming music, especially in an area with a low signal, will rape your battery life.

I have the same battery issues. It drains a lot when playing games and using wifi.
I hope Sony releases a battery fix in Ice Cream Sandwich when it's released.

+1 for betterbatterystats
Helps identify any annoying apps keeping the phone awake. Had an old version of getjar which was a pain in the backside doing kernel wakes all the time!
I'm on stock and I get a bit obsessed about trying to get my phone to last 2 days, even though I work in an office so could charge whenever I want.
So I end up not using it to it's full potential tbh.
However for me I did the following:
Rooted
Added CWM
Flashed a zip for notification toggles.
Then turn data on only when I want it.
Also installed titanium backup.
Search on google 'safe remove apps xperia play xda'. Their is a thread which gives you loads of stuff you can delete (after backing up with titanium of course!. Not only did it make my phone feel so much more responsive (freeing up RAM obviously), not having those apps does make a difference to the battery life.
I can now go with 30mins gaming, some texting, a short call or two and checking twitter / fb, switching to wifi when home in the eve and have all connections turned off over night and manage 30-40 hours from the phone.
That I can cope with

[Q] Arconium ICS 2.2 issues

Hey everyone! I've installed arconium ics 2.2 with stock kernel as suggested on my arc s. It's a fantastic rom, with all the smoothness and response.. but I have a couple of important questions.
1)Does the battery drain really fast once you start using the phone? Cause just over a minute or two of 3G web surfing, I lost a percent of battery. Otherwise in standby, it's great! It's just that I felt the battery drained more slower in GB.
2)In No Frills CPU control, which would be the best governor and settings for lag free performance with as less battery consumption as possible.. I know everyone wants that, but given so many options, and even going through the summary of what each governor does, I'm still confused..
3)The 720p video recording lag issue, although its widely known. I would like to know if it can be completely rectified in the upcoming updates. It's because I use video recording many times and it's just as important feature to me as everything else in the phone, otherwise I would have to switch back to GB again.
P.S. The only widgets active for me are the status bar, weather (updates every 2 hours) and world clock.
Thank you for taking your time to answer my questions...

I got the problem with massive battery drain after my flash yesterday.... :
Stock kernel with % Battery mod

Have you tried disabling the torch and brightness widget buttons through quickpanel settings?
It also depends on your wifi usage, background processes (which I think you have a lot) and many other little things you may have overlooked. I've managed to get 1% per hour battery drain in standby mode. But once I start using it, there's this massive drain.. :/

Fixing battery drain on your s3

I have done pretty extensive testing in the last few days and this is what I found.
TOUCHWIZZ USERS ONLY, uninstall and delete data for the app my uploads. It syncs your gallery with picasa and uses a load ofdata and battery. It won't break anything. turn off instant upload in Google+. Turn off smart stay and motion actions. they use about every sensor in your phone. Turn off the wake up phrase in s-voice. If its on it is always listening for that phrase. I'll keep looking for other things but I got fairly good battery life just doing those things right there.
When uninstalling an app, wipe cache and data first. This will clear any background processes that could stay after the app is gone.
Install es task manager and kill everything you don't need to run on startup to preserve boot time/battery usage. Also it will keep the processors a lot lower.
All accelerometer and other hardware functions use a significant portion of your battery. If you don't use landscape mode turn auto rotate off because it uses that precious battery life.
Weather bar in notification drop down and on your lockscreen will destroy your battery life. Weather widgets also use quite a bit of battery.
Facebook app also kills your battery because its always connected to the internet. Syncing Facebook account to your phone further wears down your battery. Any game or other app that connects to facebook will also do the same.
Look in data usage under settings. Anything on that list uses more battery because its connected to the internet.
If your not in an lte area turn lte mode off because your device will be searching for a signal it will never get.
Low signal strength kills your battery because your phone has to use more energy to hold connection to the network. If you have WiFi at home and bad cell service (or anywhere) use WiFi because its easier it is for your phone to hold good wifi signal than bad cell signal. also turn off your NFC. It uses more battery than Bluetooth does.
Get better battery stats app and look for wake locks because without deep sleep you will never get more than 12 hours battery life.
Widgets, live wallpapers, lock screen ripples and other things that move use battery also. If you don't use it then remove it to save a couple percent a day.
Remember that when charging through a computer USB port or things like that charge a lot slower than an outlet. Slow charging is better than fast charging because your battery stays cooler and that means your batteries total life will be longer.
Finally before you go in a ROM thread and start complaining about battery life, go at least three charge cycles after flashing to optimize your battery.
There are many things that cause battery drain so beware when you download that next app. It could be a battery sucker. If you don't need or don't use an app. Uninstall it because it may have background processes that are using up battery and RAM.

The other thing I might add is the "wake up phrase" where ever that is. I found it yesterday and turned it off. Helped a lot.

You can uninstall the facebook app, go to facebook on your browser, create a bookmark, and then place a widget on your homescreen for that bookmark. The site is actually faster than the app.

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

ii.Mediaserver. This system process is tricky when it comes to battery. What happens is that whenever you access any sort of media on your external SD card (playing music, gallery, what have you), this process kicks off. Luckily though (but hard to catch), sometimes, this process uses more process time than it should due to corrupted contents on your external SD card. In order to catch this culprit: try clearing your battery stats (for example, restarting your device or coming off AC power), playing some music and/or checking out pictures on your SD card for a few hours. Then, check your processes. If Mediaserver is high up there in usage, you may want to consider cleaning up your SD card. Naturally, we would expect that the process is higher when media contents are in use. I can’t give you a specific guideline such as, "something is up if Mediaserver consumes over 25% battery." This is another example of where you should look up other user stats for system processes based on your specific phone and OS version. If you think your SD card may be corrupted, backup your data, format the device, and slowly, add back files and repeating your media tests. Finding a corrupted file isn’t a guarantee, but this doesn’t hurt if you suspect data corruption.​[/QUOTE]

Turn off GPS when not in need. Turn off WiFi when not near wifi. All the stuff in the op. And undervolted by 100+ mv on every CPU setting. And my phone is absolutely lag free accept when I hit the unlock button it takes like half a second for the screen to come on instead of instantly (160mv undervolted on 192 which is sleep speed I set)

Maps is known for that. If you don't mind my asking what do you use maps for and could you just use Google now to search locations and it will even give you traffic n stuff. That would probably get you another hour or so a day.

[Q] CyanogenMod 10.2 Alpha (Build 3) --- great stuff, but battery drains fast

Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

ok thanks let me do some reading.
Also yesterday I deactivated the SIP app and that helped of course. Still strange that the app consumed to much less power on Gingerbread compared to CM10.2
Thanks,

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration

That sounds very good, let me try that!

I have the same issue with increased battery drain. Yet I've not been able to identify the source. I disabled a lot of services (with Disable Service), also deactivated unnecessary system apps.
Cell standby is also shown as a huge drainer, although I usually have a good signal and no losses (checked with Better Battery Stats). There are no wake locks out of the ordinary.
Now I'll try battery calibration to see if that helps at least some amount.

Actually for me nothing really helped.
I eventually identified the 3 apps that drained the battery via Wakelock detector.
Those apps are Facebook, GMX Mail (based on K9 mailer) and CSipCimple.
Before the update to 4.3 my wifes phone was running the stock gingerbread and did not have an issue at all with those apps.
Yet on CM4.3 they are draining the battery.
Once I uninstalled the apps the batter life is back to normal. Which is sad, because she needs those apps. But no other solution so far from my side....

Again the myth with whiping battery stats / battery calibration. Make a full charge and unplug the charger. This will whipe your battery stats.
And for the ones who never get this. The stats are just some data about apps consumption collected while the battery gets discharged. The ROMs are whiping them by itself on each full charge and after shuting down the phone.
This data has no Infulence to how long a battery lasts. It´s just collected to show you visually the statistics.

At least I thought it helps with the effect that the first 50% of the battery last 3 times as long as the last 50%, but not even that changed

I had the same problem with my S4 running CM 10.2 stable. The battery was empty after 8 hours. What I did was to change the theme, and today i got 12 hours and only 20% of the battery gone and wi-fi/3g all the time. Well, I still have only one hour of screen up time, but that is how it was before... I don't know, i'm just saying! Maybe it helps. The theme i added is LunarUi 2.
All the best!
