I was wondering how I could extend that battery life on my DINC? Any suggestions and tips would be great.
Ah yes, the battery issue. One I am all too familiar with.
Easy:
For whatever reason our phones charge to 90% and stop there. To correct this, you can either charge while the phone is off or do what we call a bump charge. Bump charging involves charging the phone to "full" while its on (the light should be green) and then turning it off while still plugged in. The light will then change to orange again for 30+ minutes and then green again. You will then Really be fully charged.
Also make sure you have GPS and Bluetooth off when you aren't using them. This will help a ton.
There is an option in Settings - Wireless & networks - mobile networks - called "enable always on mobile data". Unchecking this will drastically help save while the phone is asleep on the 3g network. However, doing this will affect how often you receive updates to chats and sync items when the phone is sleeping. To me it isn't a big deal since if I'm not using the phone why should it be working, but everyone is different!
Finally, a rogue app might be nomming away at your battery. An app from the market called System Panel will monitor how much battery each app is eating. Its free initially but if you want it to monitor over time in the background it does cost. However it is definitely worth it since its a great app and useful for any android owner.
Intermediate (has cost):
Evo batteries fit in our phones! The fit is a little tight but it works just fine. Our stock batteries have 1300mah of capacity which is a bit on the low side. The evo battery has 1500, so it's an hour or so better. You can buy them cheap off ebay (OEM Evo Battery) for around $15.
Conversely, there is the official extended capacity battery for our incredibles with a massive 2150mah. The trade off is that it adds bulk to your phone and costs a lot (around $50). There is the third party seidio battery which adds even more capacity (3500) but adds even more bulk.
Advanced:
Are you rooted? There are kernels out there that are undervolted like Hydra kernel, adrynalyne's undervolted and kingklick's voltage scaling kernel. Everyone has differing experiences with them so there's not a solid "best" so to speak. You can flash these kernels using the clockworkmod recovery. This will all be nonsensical if you're not into the Modding scene.
Also if rooted, you can underclock the processor which, depending on the kernel, can help drastically save battery. You can set profiles to have the cpu work at a minimum speed while the screen is off. Kingklick doesn't advise using setcpu with his kernels and it straight up wont work with hydra's, but it can do wonders on any others.
--
Depending on your activity, you should expect 4-5 hours of 3g awake usage and around 5-6 if you're mostly on wifi using the stock battery. 3g can be a battery drain if you're in an are with inadequate service.
Hope this helps!

turning off gps doesn't matter all that much. GPS isn't called upon unless you have an app using it. I have mine on most of the day (for tasker profiles) and have no issue.
Use WiFi when available, its quicker than 3g and takes less battery.
download setCPU (from xda) and make a profile for screen off max/min = 400/245 or something like that.
i have 'always on data' checked, no issues for me
kernels help a ton, kk#5 is a beast.
I'm running uncommon sense, kk#5 and the above settings. I'm on 20 hours unplugged with 35% less, standard usage. -- not bump charged, charged while on to 100%
isn't the system panel app like a task killer? and from what i've read task killers are pretty pointless with froyo......however i have noticed that my phone is constantly running with about 140mb of ram free, i don't know if this is usual or if something is wrong?? i just got my Dinc so i'm new to all the tweeks and tricks, i do have mine rooted though. i'm not that up on changing roms and kernals though so i'm just trying to find out what all i can do to help my battery without having to buy a bigger one. any help would be greatly appreciated!!
If you are rooted and aren't comfortable with flashing ROMs and kernels, look at setcpu that was mentioned before, and search for instructions to remove the stock apps that always startup on their own in the background. Unless you actually use them, then you can't really do that obviously. I don't have any times on how long it lasted before and how long it last now but I do know its improved. I have mine at a processor clock speed of 500mhz and I don't see much lag time unless I'm really running a lot of things. I'm on WiFi listening to Pandora and I'm not experiencing keyboard lag while typing this.

no...the max it'll run is 1.19 ghz. worst that will happen is a bootloop which can be fixed through nandroid.
Just increment a little at a time. I usually run mine at 1.075 ghz w/ on demand.
screen off profile max/min - 450/245
I use JuiceDefender on my Incredible and believe it or not it really works. It's turns off your data while the phone is on sleep mode so no battery is being drained. I get at least 5 hours extra battery life. You also get other features that come along with it so just give it a try It's free!

Yes system panel CAN be a task killer but I do not suggest using it as such. Instead, it does a great job monitoring how much CPU each app uses so you can take educated action.

1. If you use location based services and have GPS on, it will use the GPS module quite a bit. This is certainly a battery drain.
2. If you dont have any issues with always on mobile data then you must be in an area with good coverage. For me if its left on it drains my battery quite a bit because I'm in a flaky coverage area.
Everyone's phone is different though. Finding what works and what doesn't is the first step to perfection. I just installed the new skyraider sense and my battery life has been ultra fantastic. It works great for me, but I know others dont have that success.

I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)
I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!
Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.

a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol
1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

Well, if you keep data or wifi turned on at all times, then there's no way you can have something more than mediocre battery life, sorry.
It's not the Atrix'es fault, its the brutal truth with all modern smartphones.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.
I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.
Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .
The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).
These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)
P.S.- Please don't post "My battery lasts for over 9000 hours." and think that's enough info. Use your head.

I hardly used my device at all and in three days the battery had been reduced down to this.
I'm running stock and I'm using mkernel. What's the operating system doing when my device is idle to consume all that battery life?
Most likely location based services such as Google Now.

No, and it's not recommended for this kernel. You probably have some application using the CPU. And keep in mind, that's over 3.5 days, so it's not too be worried about.

Not really sure what you are looking for.
Your tablet is configured differently (read: installed apps & their settings, never mind ROM & kernel differences) than the next person's, and those configuration changes alter the activity on the device and therefore the amount of power it consumes vs time. If what you observe is unacceptable to you, you need to drill down into the details to try and optimize things. But it really is impossible for anybody to guess (from a completely blind position on the other side of the internet) what might be the cause; if that is indeed anomalous consumption compared to some benchmark (pure stock, no market apps installed & a dormant gmail account?), the cause could be due to an unlimited number of different causes.
Perhaps you want to use that app BetterBatteryStats ($2.89) to find out about wake lock usage.
FWIW, my rooted stock 4.2.2 N7 grouper tab seems to discharge about 4% "overnight". Call that 10 hrs or so, so maybe I should expect 10% discharge per day while idle and unplugged. Your result seems to suggest 16%/day; but I've made no effort to dig in to things on my end of things - and besides: my results are irrelevant to yours as I no doubt use a different collection of apps than you and possibly different settings for the stock apps, too.
In my case the idle drain rate isn't a very compelling use case - I use the tablet every day, and when it is idle it is plugged into its' charger. If it should happen that it sat idle for a couple days, it's gonna be at 100% when I decide to use it.

And the problem is?
Around 6 days of standby, and you want to improve that?
If you want to improve that, turn off your tablet. I'm sure u can spare those 60 sec two times a day you turn on your tablet to check mail.
Keep WiFi off when not in use and you should see a great improvement. I use stock kernel and over that same time period my battery is about the same with about 3 hours screen on time. I only turn WiFi on when I'm actually using it as anything I need synced goes to my phone.

Try better battery stats and see what keeps your cpu from going to sleep state..With this way you can examine what drains your battery my friend.,.
Try turning off auto-sync. (Data usage settings)
Never keep wifi on when sleep (you will lose notification to chat programs, social network app notifications when sleeping)
Use wifi powersafe mode.(Wifi advance settings)
Turn off/disable unneeded background update/apps/extensions/services and flash a rom with minimal google stock apps)
Of course, check for apps that are currently consuming power if any. (App settings, internal application setting)
M kernel also defaults cpu max to 1500Mhz ; stock is 1200. M kernel also sets gpu to 446Mhz ; stock 416Mhz. Altho this numbers might seem minimal, it can affect your battery life considerably shall there be background processing or even right after you start using your device again despite minimally in your case. (Use n download trickstermod)
These might or might not help you in getting more standby time, try and experiment =>
If you are also looking for more screen on time and if you know and accept the risks, you can try undervolting the cpu, gpu and ram in trickstermod, you can also use rootdim to go lower the screen backlight further, but do not go lower than value 4/255 as that is 'off'. thankfully you can set it to not go below 4 in the in app settings before you play with it. My configuration pushed to 8hrs+ screen time without any gaming =>
Do note that li-ion/poly batteries need to drain over time for batt health reasons. They generally last longer if kept in the 20-80% range. Room temp can also affevt battery drain significantly, cold < 26C room drains the batt real fast; and so does hot rooms >34c due to temp & conductivity relationships (batt needs to suply more due to less conductivity in the circuits when hot)
Hi,
after I overclocked my device and used custom ROM to reduce lag the battery was drains fast and overheat and I used the factory image(in android 4.3) to get the stock kernel and stock ROM my device not overheat anymore but still drains fast and the charger sometimes when my device is on charges slooowly and sometimes while it plugged in it don't charge it decrease 1 percent and stop charging while playing any game and the charger smell like burnt and it charge first while my device is off but that didn't happen to me before the overclock,
I want to know I there are way to increase battery life and fix the charger problem,
Thanks.

A Few Apps For Battery Life
There are a couple things I would do, first is you need to monitor what is draining the battery. One thing to note though is your OC is obviously going to drain the battery quicker than stock and your governor setting could also affect this a lot. I am guessing your custom ROM has a non-stock kernel with it, if not I would recommend Franco's Kernel (r75 is the latest) and he even has an app that will keep you updated and flash for you (https://play.google.com/store/apps/details?id=com.franco.kernel&hl=en) there is also a free version of that. Franco's paid app has a built in power settings option that lets you adjust power usage per app that could be extremely useful in your case. However I would do some monitoring first and make sure a live wallpaper or a hardware monitor is not draining more battery than you think it is.
I've used these two apps and both do a great job of letting you know what is using the battery most during load/idle/sleep:
Better Battery Stats:
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
Go Power Master:
https://play.google.com/store/apps/details?id=com.gau.go.launcherex.gowidget.gopowermaster
Android Tuner (does A LOT for the price, including battery monitoring), If you are rooted this is almost a must buy:
https://play.google.com/store/apps/details?id=ccc71.at&hl=en
Also in Android Tuner and I think Better Battery Stats (I've uninstalled it since I got Android Tuner) there is an option to turn on a fast charge option. Fast Charge will decrease the time to charge the battery, however I haven't used this feature because it sounds like there must be a catch (more power to the battery quicker isn't going to be at stock spec power delivery from charger to battery). If my N7 was having trouble charging, I might consider it.
Really the first thing you need to do is install one of the monitoring apps and watch what is using your battery the most and if something is using it a lot that you didn't even realize. I was using UseMon to monitor and it was using 36% of my total battery usage, so I ditched it.
Then you have some things you can do to save your Battery
You have Juice Defender which has some great options in it if you are draining the battery too quickly:
https://play.google.com/store/apps/details?id=com.latedroid.juicedefender&hl=en
It comes in 3 versions Free, Plus and Ultimate.
One of my Favorites that saves the battery is Lux Dash:
https://play.google.com/store/apps/details?id=com.vito.lux&hl=en
There is also a free version, but this is easily worth the few bucks. It uses the camera to read the lighting of the environment you are in and based on the ratio you set, will dim or brighten your display. This method trumps any of the built in features, like NVIDIA's option.
Those two apps will help your battery a lot, especially if you also use the monitoring programs to see what is draining the battery so quickly.
You can read this article on some apps for monitoring and increasing battery life: http://reviews.cnet.com/8301-19736_...s-that-prolong-your-smartphones-battery-life/
and: http://www.talkandroid.com/guides/b...pps-for-analyzing-and-improving-battery-life/
Note these reviews/articles mention a lot of apps I have never tried nor mentioned, so be sure to read instructions on use carefully.

You can read this article on some apps for monitoring and increasing battery life: http://reviews.cnet.com/8301-19736_...s-that-prolong-your-smartphones-battery-life/
and: http://www.talkandroid.com/guides/b...pps-for-analyzing-and-improving-battery-life/
Note these reviews/articles mention a lot of apps I have never tried nor mentioned, so be sure to read instructions on use carefully.
If this helped you at all please don't forget to give me a Thanks

No problem man, glad I could give you some useful advice!
Hello guys,
I have been researching, experimenting and trying many many things to understand how cell phone battery consumption works and how to find the solution to be able to use the most of the battery! HTC did a very bad job on the battery side of M9 and in my opinion, Battery is the only downside of M9. I will explain later why I say that.
I will share the tips and tricks I found to get such battery life that none of you ever think of getting out of M9. Look at below battery stat. It looks like M8 battery stat which made all M8 user really happy with their device! Now we will be enjoying that too! BTW This is my birthday today, so its a very good day for me to post this thread. Wish me luck!
First Let me explain some things about why a phone drain the battery in relation with CPU and Apps.
1. Random CPU freq change.
2. CPU heat.
3. When phone is idle, means you are not doing anything(not opening apps or neither you have apps opened in background, CPU freq not being able to stay down.
4. GPU related drains(while playing games or not)
5. Display category. Amoled or LCD or what type.
6. Buggy ROM keeping wake locks. ( I am not going to talk about wake locks at all. There are good enough threads for this)
7. Apps. Each you open and close an app, the cpu starts working, freq goes high. So, this means, the less opening and closing you can do the less battery you consume. Now, all these concepts of app killer running in background, killing apps after a certain interval, ARE COMPLETELY WASTE OF BATTERY AND NOTHING ELSE! Android keeps opening apps in background according to its algorithm. So, if you want those app to stop bugging you in the background, then task killers are NOT ANY USE AT ALL! Remember! The less app in background the less drain you will get. We usually use home button a lot when coming to home screen but we dont realize the app just got minimized and consuming as much as battery as it would if it was open in the foreground. So result is, bad standby time + more drain while screen is on.
So how can you get rid of those background apps? Best way is to use Greenify. Greenify is the only app that can hibernate any app without hogging battery by itself and keeping wake locks. How to find which apps to put under auto hibernation list? You need 2/3 days to observe. Greenify will automatically mark those apps which opens in background. Once you are with good number of apps, greenify all of them. In greenify settings, select autohibernation so that even if some gets awake by the app, can be put to sleep again. Now two things will hapen because of this.
1. You will consume MUCH LESS CPU power means you will save battery. The device will be very snappy. Ram will be at least 1.3 gb free.
2. It will take more time for an app to open which are under your hibernation list. Now I have thought about it. My conclusion is that, I need to choose between battery and super fast device. When I on battery saving priority I follow the solutions of this threads and when I am not worried about the battery I try to enjoy the device.
So, we can restrict apps from hogging with greenify. Now how to control the CPU?
Out CPU is actually ULTRA FAST and is capable of fastest performance amongst all smart phone around. Here is the antutu benchmark to show how crazy this CPU can be! So crazy CPU will drain battery. Its cor-relational. So, the solution is to limit the CPU from putting too much power, especially when it gives more than the phone and user needs. When I was using HTC Sensation, I was feeling like, there are 2/3 things which should be better and I demand nothing more from a phone. LIke battery, camera, ram etc. But after M7 I have never felt that the phone should get faster and we should get like 4 gb of ram either~! But newer means faster and better. So CPU + GPU are getting more powerful and eventually the phone is getting such overrated power which it doesnt even need! After all we are not flying to moon with our phones! lol!~ Right?
ok Now how to limit the CPU?
We need
1. Elemental x kernel 4.01 installed with all stock configuration. This is important. Yout must use STOCK values. I have seen anything else other than STOCK values drain the battery even more! So STOCK IS BEST!
2. Elemental x kernel app or Kernel adiutor kernel config app to tune the kernel for our battery saving mode.
Steps-
- Set HTC pnp manager off
- Set max cpu freq of small cluster to 864 mhz, min cpu freq to 384
-Make sure you are on stock gov.
- Set GPU max to 320 GHZ.

Disclaimer: These settings will make the phone performance slower but not laggy. So, just consider a power saver package which has very decent speed too!
After applying these settings, you better restart your device to let settle it with new rules for CPU. leave the phone for 2/3 mins. The things that you will notice when you turn on the display -
1. No rapid CPU freq changes
2. Phone is ultra cool as the temp of CPU and battery has gone down to 35 C. M9 with default setting will never come down to 35 c ever! The lower temp would be 40 c. So, cooling the cpu will minimize mA consumption.
3. when you open any heavy app like fb or chrome you will see the consumption mA rate is almost half of what it is with default settings. Max rate of discharge was 700 mA for me with 50% brightness + 3g internet + FB/chrome/youtube.
4. When you leave your phone to sleep, here is the fun! I have never seen such low mA discharge rate on M9 and I didnt even expect! It goes as low as 40 mA! Insane! The avg screen of discharge rate I found was 70 mA which means on full charge our M9 will get 40 hours standby! And that is with internet on.
5. If you are charging with official m9 charger, you will see the charging rate is 850/+- mA while your display is on with internet. When screen off it will reach mac to 1340 mA. My phone previously was charging at 600 mA with screen off. So, now 0 to full charge is only in 2 hours.
6. Clash of Clans used to drain 1200 mA and now it drains only 550-600 mA.

Hope this helps. Please post your battery results. And dont forget to tell me if you like this post. This will inspire me to make more posts.
Thanks!
I'm in the search of the perfect battery life too haha ????. Please continue posting about battery improvements. Thanks!
My battery life goes way up when I put the phone in the glove box of the work truck. 0% drain over 5 hours, checked it for call a few times and that was it. I leave data and stuff switched off until I'm going to use it.

Instead of turning PNPMGR off, have a look at this first. http://forum.xda-developers.com/one-m9/development/mod-htc-one-m9-enhanced-thermal-t3369574
It's a pretty indepth thread on the pros and cons of PNPMGR, and also custom thermal configuration files that change clock speeds of your CPU, dependent on your usage.
Also, your Antutu benchmark picture isn't anywhere to be found.
What about CPU boost? Do you disable it?

I do all like u but my m9 is still after few minutes too hot.
I never was more diaappointed with any another of my phone and heating and poor batt life like on m9...
After one hour of browsing internet I'm over 50% down.. on stock mm. That's shame for HTC. Now I'm back on my 2yrs old s5 with still perfect battery life..
I don't get any overheating on my m9 at all. It's on stock marshmallow still. Bought it used a couple weeks ago.

Hi,
If you did an OTA update to MM and are losing that much battery in just an hour of heavy use, then I would back up everything and do a factory reset. I can go for 5 hours of very heavy power user performance before dropping to that level. Either that, or you have a malware app on the phone that is being used in the background. Which a factory reset will also solve.( except in rare cases, requiring a firmware reflash)
