I need some help I am getting a 180ma drain according to Tbattery with the HD2 in airplanemode and nothing running is this normal? I am using the energy rom
Thanks,
yonu
gsm radio alone should absorb ~5mA, so airplane mode doesn't save much.
the user kilrah has made a nice reference to leo battery drains, going by memory, 35mA for idle cpu, if you have screen brightness set high enough you can definitely reach 180mA, also considering that the sense homepage, with weather animations on, actually loads the cpu more than you could imagine.
I'd say, could be better, there are a lot of unkown factors, yet it's not something definitely worrying
ok thanks didn't even think about the animations just trying to get more than about 3.5hrs from a charge

Im looking for a rom with amazing battery life.....
Help Please!!!!!
Thanks!!!!
The rom i've found to be best on battery life is Royal Ginger. I've gone 2 days and a few hours on it with moderate use.

I also get amazing battery life on RoyalGinger 1.5
+3
I was at 36 hours with wifi on for at least 24 of that. And I plugged it in with 10% remaining.
Edit: Make sure to calibrate your battery though. Don't judge the ROM off of the first 1 or 2 days.
Thanks ill try it.....
And how do i do the thing you was saying about the battery....

Search is your friend... there are a few guides in the Dev section
Sent from my HTC Glacier using XDA App
I have great battery life on CM7. There are a number of things that affect your battery life that all need to be taken into consideration.
ROM
- Find something by a reputable team like CyanogenMod and Team Royal. Their ROMs don't have HTC's SenseUI overlay and aren't bogegd down by the extra framework and overhead needed for Sense.
Kernel and CPU Clocking
- If the ROM supports changing the CPU clock speed, you can have your device run at lower clock speeds when idle (such as when the screen turns off), theoretically saving battery during those times. There are some great kernels by faux123 in the Development section.
- You can also try an undervolted kernel. Performance is no different than a stock voltage version of the same kernel, it just uses less battery to do the same functions.
The Screen
- This eats up battery like a beast. I don't use automatic brightness as most of the time a low setting is good enough (i.e. indoors).
- Gaming and other graphic-intensive activities will chew up battery
- I also use relatively dark-colored backgrounds because I think (can't prove) that it's requires less effort for the screen to show darker colors. Somewhere I read that it's easier to read light text on dark than dark text on light, so there's that too.
Connections
- GPS takes lots of power to use, so keep it off until you need it.
- Wi-Fi and bluetooth will continuously scan for connections while they are on, so leave those off while you aren't using them.
- In areas with poor network signal strength, your phone uses more energy than in areas with great signal strength.
Apps
- Be selective about which apps you install and run, especially ones designed to run all the time. I like to have something that can monitor CPU usage so that I can see when something is hogging system resources. Kind of like the Task Manager in Windows.
TasKillers - DON'T USE THEM!!!
- TasKillers cause more problems than they solve. Android is better at closing idle/unnecessary tasks than any TasKiller app.
- Killing tasks with TasKillers also adversely affects the stability of your device.
- Many of the things killed by TasKillers end up restarting anyway because they're needed for something, so you're repeatedly killing and starting the same apps over and over again. Guess how much battery that saves (hint: less than zero).
- If anything, use AutoKiller Memory Optimizer. This doesn't kill apps, it changes settings in Android that determine when to start closing apps to free memory.
Thanks you very much!!1
The biggest deal that has to do with battery life is how hard you push the phone. It has nothing to do with ROM or kernels...
If you truely wanted to test a ROM to see how the the battery life stack against each other you'd have to have x amount of devices with the SAME EXACT settings within the given ROM. Each phone running a different ROM. I ran a Sense ROM over the weekend and got HORRIBLE battery life. but other claim Cyanogen is the pits.
What are the best ways to save battery on a zte blade using latest cm7?
Sent from my Blade using XDA App
I would love to know if anyone can describe what their battery life is like. I am using cm7.0.3 and after full charge, on stand by mode I have 80% left after 8 hours. Is it good? Bad? Tips to improve this please!

Tips: amoled therefore use black background
- lower brightness
- disable data connection
- use task killers
I get around a day's use with fairly heavy usage. But games do suck the juice up.
@Drupad yours sounds good, although I'm using N78.
Use Green Power from the Market to turn off Wi-Fi when screens turns off.
Don't overclock.
For my 2¢, I've been using the SMARTASS kernel governor for a while with pretty good results for standby (CyanogenMod settings, Performance, CPU settings).

Hi Oly, Nice to see a familiar name in this forum I was wondering if you are as regular here
If yours is bad - I guess it's because of CM7.0.0 - upgrade it, they have fixed that bug (read on CM7 forums)

My brightness is set to 'auto' - should I stop that?
I don't use data connection for anything other than email sync. However good you mentioned task killer. I have installed advanced task killer and set it to kill all tasks when my screen is off. However, as soon as I activate the phone from sleep mode, I can see at least 8-10 apps already active! - could it be a dodgy task killer?

I get more than a day actually now that I've upgraded to latest nightly CM7. They seem to have fixed to battery drain. I charged my phone last night. I've listened to about 45 minutes of online radio while travelling, made 1 call (about 2 mins) and played angry birds for 10-15 minutes. It's been 9 hours since I first used my phone and I have 53% battery remaining. I am also using a live background with auto-screen brightness.
In a nutshell - I think CM7 N85 is better than N78 - give it a go if you like!
I don't use Wi-Fi. I only use data connection from Orange (they seem to have given me unlimited internet so will get as much as I can - yes because I don't like Orange.)
Overclocking doesnt seem to work on my blade. Anything more than 604 and my phone restarts if I use more than 2 apps!

hi drupad
task killers are different in android apps need to constantly run in the background
its just the way it is (not like WM task manager!) it's normal for the apps to start running again after standby
thanks for pointing out cm7.0.3 changelog thingy! i'll try to reflash to 7.0.3 when im free sometime
unfortunately i'm not as active in SF forums as much... (more in sgs2 + sgt forums)
you should check out the modaco SF forum,! i think it has different roms there!

I spend almost 3 nights (nearly!) reading Modaco forums, but nothing impressed me as much as CM7! CM7 was the only ROM that had most if not all feature functioning. I am presuming android custom roms have more 'functionality' issues than WM! And if you are going to 7.0.3 - also get nightly 85! It's Gingerbread 2.3.4!

thanks for advice mate
also to my previous question, i have my brightness set to around 50% (not on auto)
also, i advice to use normal wallpapers, not live!
(as pretty as they are, they suck up power!
also drupad, coming from an fellow spb shell winMo fan, you could give SpB Shell 3D a whizz on your SF
i made a thread abt this (tg01 forum) some time back comparing it to spb 3.5 winmo.
it is faster than it was on tg01 and a bit prettier
also it may save some battery.... (if you should, try launcherpro - i think its really good for battery too!)

Thanks a lot for that advice mate! I had completely forgotten about the SPB Shell! It will be very interesting to see how it integrates to already beautiful android layout! I am going to give it a go straightaway! Will report back soon.. I used launcherpro for a few hours, but soon realised as customizable as it might be, it's only good if I buy a full version (gives more options!) So ended up uninstalling. Won't be spending much on market just yet, may be after a couple of pay days
It's AWESOME! Definitely better than Stock, AWD and LauncherPro! It's sleek and smooth. I like it already.. however, will give it some try in over-all functionality. The app drawer scrolling has improved by 150%... Doesn't lag AT ALL..
Thanks for suggesting this mate.. If the functionality is good for day to day use and if battery drain is minimal, then this is my THE APP!

yeh it's very smooth somehow! launcher pro / stock app drawer is laggy and choppy to scroll through, but buttery smooth on spb!
new carousel is a nice improvement on the android version compared to wm3.5 right?
it is actually incredibly smooth on SF ! it is also cheaper than WM version..
however, i only use it on my SF, not on my other devices... (some reason it lags a bit on my galaxy tab... )

Kernel governors from my understanding help determine the way the device responds to dynamic frequency scaling.
Performance is the best for device response but consumes the most battery as it's hitting the upper frequency constantly. Powersave is the opposite as it's hitting the lowest clock speed constantly.
Interactive polls cpu demand based on a timer rather than just currant demand (uses a bit more juice than ondemand).
Ondemand gives a good balance between response and battery.
Conservative is similar to ondemand but ramps up/ down to currant demand more smoothly (at the detriment to response).
Smartass governor caps the max sleeping (ie. screen off) frequency to 352Mhz, so uses less battery. However it acts like Interactive when the screen is on & can use more power than ondemand.
For me Smartass works best on my blade, however on my N1 ondemand is better - go figure

Yes 120% smoother and improved carousel! I think they've got it almost right this time.. I've noticed the reduction in SPB widgets though. Thought they might give integration to most of the shell. I wonder what WM users might do without these integrations, widgets. I think buying SF is one of the good decisions I've made this year - it's worth the money for android phone! (Still jealous of your SGS2 though!)

Thanks a lot for that Harmohn, that makes sense now! It's more or less CPU performance profile in a way, right?
Now it makes more sense to put it on SmartAss! It's been working fine so far, but I am not overclocking at all. Will stick to 604, 122 for now and that saves me a bit of battery hopefully!

Glad you moved on from Tg01 after orange's bad service!
I've been researching extensively how to improve my battery life on my Android phones and I believe I've found an amazing setup for the Atrix. My phone has been disconnected for 3:15 and I'm at 91% right now with moderate use. It used to burn about 5% an hour before with NO use. Yesterday, it lasted 14 hours and I still had 20% left when I went to bed.
Aura 1.1.3 Debloat #7 ROM
This ROM seems to be the lightest one I've tested. It's only 150 MB and very fast.
SetCPU
I set up a profile to underclock the processor all the way to 216 MHz when the screen is off. The processor is running at 1.1 GHz max. I haven't tested underclocking it to 1 GHz or 900 MHz. I'm sure that would improve the battery life even further and not have a huge impact on performance.
Battery mode (Android settings)
Obviously, it's on maximum battery saver.
General settings
I set the screen timeout to 30 seconds. Maybe 15 seconds is too short for you as it is for me, but that would save some more juice.
Every other battery-killing feature is on, like wifi, GPS and sync. I don't use task killers anymore and found out that my battery life actually improved a lot after I ditched Advanced Task Killer.
I just wanted to share this with the community. I hope it helps you. Any suggestions to improve it even further are very welcome.
Yeah task killers are pretty much useless, watchdog is a wonderful alternative.

Interesting and thanks for sharing, but...
I can get almost the same results by using any other ROM without SetCPU and just using Max Battery Savings but I'm not interested on that setup because I need to have PUSH email all day.
Maximum Battery Savings makes push emails useless, and for a device that's supposed to be "connected" push mail is a must (at least for me).
Unfortunately, push mail is what kills batteries, specially on 3G/4G.

My phone was maximum battery savings one time for some reason. I didn't do it. But for some reason, it was seriously draininng my battery bad. I think i was on 2.2/froyo before i unlocked so i don't know if that had anything to do with it. I do know, i haven't had reason to try it intentionally since my battery is great overall. It does help since atnt turned up the juice on the 3g and called it 4g reception has been very satisfactory lately helping power consumption by not having to look for a signal as often.

Exactly! When the phone switches back and forth 2G and 3G/4G it drains a lot of power. So it too depends on the zone we are in at the moment and that's one of the reason we see a lot of different results among users. Of course, phone and app/game/internet usage style also counts.

I think a lot of people don't realize that terrible reception can account for terrible battery. Often we don't get that feedback when people are whining about battery. Also, lots of the people whining about battery play lots of games, and some of those games that put the gpu through it paces suck up juice faster, but the user is not realistic about that either and expects battery life of a phone that is used lightly.

Yay for undervolting
not "killing" aka "ending" or possibly more familiar "closing" your running apps.. that's like, like if you log into your windows box and you don't have the "X" buttons on the window caption bar.. you just leave everything that you run running until you shutdown..
before you even try to retort, obviously there are exceptions. in windows explorer.exe runs endlessly until you shutdown. on your android device that's the equivalent of your preferred launcher.
what else.. msn? the equivalent of your favorite sms app. facebook and notifications? similar to that browser you keep open with 5 or 6 tabs swiftly consuming your precious processor.
i'm not sure an argument even exists. "task killers" has "killers" in the name which naturally has negative connotations. call it a task manager. windows has a task manager.
other than that nice tips
I am stock everything.. even launcher
3hrs 14min screen on time
~12ish hours off the charger
still says 50% battery. which means 50%-59% on motoblur
pretty darn good eh?
Don't understand the point you were trying to make. Are you saying killers/manager is worthwhile or were you trying make a worthless point about the names?
Anyways task managers are worthless. A good comparison to make are mid/high end laptops and their ram. On a forum I frequent, users were comparing their battery runtime with similar setups. Some were getting extra ~hour or so than others who couldn't figure out why they were getting shafted on battery. Some people don't realize that 4 dimms of ram consume twice the power of 2 dimms of ram no matter the gb of x amount of ram. Thus its better to have 2 dimms of 4gb each than it is 4 dimms of 2gb. The ram consumes power whether you use it or not if it is connected. The 1gb of ram in the atrix consumes the same amount of juice whether its holding 300 mb of data or 800 mb of data. Whether the cpu is computing with something active or not in the ram is what's relevant. Task managers only help when you have a rogue app. Id rather uninstall it then deal with a poorly written app.

Although that may be true for windows computers it its not with Linux which Android is based on. I know that there are virtual machines and all that jazz for the apps but the core system is all Linux and it's even optimized for battery life so when you press the home button yeah that is still running in the background but if you ever need to use that ram it either clears that app from the ram or (based on the app) kills its altogether. And like someone else said ram uses the same amount of power weather it's being used or not.
Also if you're using well written apps then they shouldn't be using any CPU in the background.
If there is some app that's hogging CPU in the background then you need to just uninstall it. Task killers especially auto task killers are actually using a lot of your CPU constantly checking for apps that are using too much ram but Android already does that automatically.
tl;dr
Linux can manage its own ram without you and for the love of God, stop using task killers they're making everything worse.
i was defending their usefulness in general not so much their effectiveness in battery preservation. probably the wrong thread. if any its minimal.
i'm talking about active task management tho. when i'm done browsing the web and want to fire up pewpew for some old school polygonal destruction i kill the browser entirely. i guess its really based on the type of user you are whether or not benefit is to be had. some people are active while others are standby

Sure, it depends on how you use the phone and the strength of the signal you're getting in your area. Would you guys just turn data off in bad signal areas to save battery? How would you handle that?
This is what happened. My battery is doing amazing. I changed the battery mode to Performance during the day and I still have 65% after 12 hours. Not bad. It's about 2.9% an hour. The display was used for a total of 2 hours and 10 minutes.
Battery life posts are useless unless we have some kind of standards during testing.
Like setup your system and then a 15min phone call, 1 hour of video/ ect.. same call.. same video same ect .. ran on each battery setup will give a truer idea on what saves battery the best.
This whole .. it was off charger for 5.33 hours and I used it alot and its at xx% doesn't hardly mean anything.. how much use is alot? How much is little?
Need some kind of same standard test that can be run..
nice to know

Mostly its not about the ROMs you use, but the Kernel or Baseband (Radio) firmware.
At least for me it's been much better than with the original ROM.
Also you must take into consideration other factors like type of use, voice/data signal quality on your area, and many other factors.

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)
