Can Removing Daemons/Services Save Batt Life? - HD2 General

i got an unmodded and locked TMOUS hd2. i'm new to modding. is it possible to remove any unnecessary background daemons or services in order to save battery life? if so, how?

All you need to do is disable them - or try a custom rom there are minimal roms out there for you. They have great battery life and speed.
If however your battery life is the issue, just disable BT, 3G, internet and reduce your screen time to a minimum, that will have a big effect on the battery

What effects Battery the most?

Been trolling the forums, for a while, and I am wondering.. what effects battery life the most.. type of windows rom? the radio? kernal? or Android build?...
thanks guys.
Antartica or Panama? Where, when, how?

Operating system? Screen colors? Flashlight for movies or photos?
Battery - energy loss or charge? Age - recycles from deep discharge? Plugged for longer than needed? Air temperature or silicon cased? Temperature with heavy energy drain?
Not a simple question.

As far as software goes, the biggest killers of battery I've noticed have been push notifications and wifi. Turning both of them off almost doubled my battery life. I now have my emails synched every 10 or 15 minutes instead.
In addition to wifi and push, a big one maybe the biggest, which is often overlooked, is screen brightness. These big giant screens burn a lot of battery. Keeping it as dim as you can stand it will actually save quite a fair share of battery

I feel silly for not mentioning that one myself now
heres a funny thing i found, i replaced my Apacer 8GB Class 4 card with a Sony 8GB class 4 card. the phone use to hang with the apacer card.
the thing is, ever since i´ve made the change, the phone sucks up twice as much power.
Theres great ways to make your battery last here too:

Calibrating Android's battery read will allow Android to fully charge your battery, and if you have battery profiles in setcpu, then the app will scale your processor speed by a more accurate reading, giving you longer battery life. I did it on the couple of builds I use most, and it really does make a difference
And dont feel silly john, I sometimes take my enormous screen for granted too
Edit: hmmm maybe my class 2 is why i get good battery life, maybe a slower r/w speed sucks less juice?
well, i know all of the normal tricks.. like screen brightness, wifi off, email push...
i am just looking for a windows rom, a radio, and an android rom, to get the best battery life...
thanks again guys.
Have a look at my signature.
Data enabled, push every hour only 5mA in standby.
If it is in airplane mode it only uses 2mA most of the time. That's quiet good
From what I can tell, the single most important factor for better battery life is using an auto boot app, such as Exceller's, to boot into Android soon as possible. I set mine to auto boot in 3sec. If you let WM/Sense boot fully, you will experience higher than normal battery drain; around 60-70 mA drain in standby. Also, try installing Advanced Configuration Tool in WM and enable all options under Power Management. Have tried these techniques with pretty much every WM Rom and Android combo and average around 3-9 mA draw in standby with wifi, sync, gps and data all enabled. This translates to about a day and a half of moderate use for me. Also, remember that Sense builds tend to use slightly more battery than non-sense builds.
This method really works! The simplest way!

I have trying different things for some times as why my HD2 was always 60mA+ power drain but some others reported as low as 5mA in standby mode. I tried different builds and different settings but none worked. I almost want to flash to change my stock rom or give up the idea of using Android.
Thanks to you! Follow your way, I now only 9mA with my stock rom. A considerable improvement in battery standby.
Thank you very much.

It doesn't really, mV is a measure of state (what condition your battery is in), mA is a measure of change (how much power is currently leaving/entering your battery).
Download current widget, free from market, to track the current (= in mA)

Current Widget. Set it to update every 60 secs, and then leave your screen off for more than 60 secs, turn the screen back on, and check the widget.
Battery drain with screen off should be somewhere between 5-9 mA
Nice tips here guys...
My battery meter in the status bar looks about 60-70% full, but battery widgets say i have about 50%.
Does this mean that I need to calibrate?
I tried to delete the battery stats with Droid Explorer but it seems to be in read only? (It doesnt do anything when i click delete).
I guess I'll set up ADB and delete that way.
Also I seem to get better battery without LED me know, (why do i need this?)

Just run terminal emulator on your phone and type:
su
rm /data/system/batterystats.bin
oh, you can do this on the phone.
Thanks bro!
I hope to see improvements as my theory that the status bar battery reading vs widget battery reading being so different = it needs calibration.
Edit
I am now using Exceller's auto boot, and the my draw peaks are waaay lower, but the idle has gone up! (60-80 now...)

Battery life with WP 7.5 / 7.8 - your thoughts?

Hi XDA!
I wonder if anyone is using WP 7.5/7.8 in productive daily environment, as my feeling is that battery life is really short. While fully charged and camera trick applied, i got a drop from 100 to 75% charge while using wifi for around 15 minutes (downloading apps).
With android installed as nativesd, i´m able to use it for max 2 days w/o charging.
What is your experience with these roms?
Thanks for your opinion!

Bit of a waste of a thread. Have your searched? First rule of XDA
Are you sure "camera trick applied" properly?
This battery usage seems a bit extreme with camera trick.
Also, maybe your battery is no good/old

Got Lumia 610 updated through NCS yesterday, while battery was fully charged.
Earlier, on WinMo 7.5, on a daily average use, the battery use to shell out at least 3-4 days of power with the mobile data connection enabled.
But, on 7.8, the battery drain is actually more, only after a day of use, the battery level dropped to 43% showing 19 hours of standby time.
That's just the stock ROM, from Nokia, haven't had any experience with custom ROMs.
Maybe the CNN application and Hike messenger are drawing on more power.
Thanks in advance.
advises for all WP7:
- turn off 3G, use E (2G)
- turn off BT and WiFi when not used
- increase or turn off mail checking time
- dont use (or reduce numbers) of Live tiles
- turn off background tasks in settings - applications - background tasks (after that you must manually update this applications but you lower battery consumption
also you can manually turn on Battery saver, go to "Settings - battery saver" and check "Turn on Battery Saver now, until next charge"... notice: with this apps wont work in background, emails not be received automatically...

Thanks dxdy. I yesterday installed pdaimatejam's "1_HD2 Pdaimatejam Rom Wp7.8 OS 7.10.8858.136 RMT v8.7" custom rom on nand. Battery used to drain very fast. Now did what you said and applied the camera trick too. Whatsapp running in background, with 2G, battery current after 2-3min idle is -19. Thats the lowest I can go. Before it was -178 at idle. So is it normal now ?
And I have not tried nand android ics rom. Do it have a better battery backup than nand wp7 ?

How much battery life are you getting now? I'm also having problems trying to squeeze out life of wp7.8 which is a shame seeing that the rom otherwise is completely functional.
Also what tool are you using to determine the current draw?

Did you obtain root? If you did not, then there is not much else you can do. The only thing left is juice defender. While it does prolong battery life, most people have found that it causes more problems along the line.
if you do have root, then you can flash customer kernel, which helps battery life a lot.

[Guide] Optimizing Battery Life

Hey Guys, Kyuubi10 back again with a quick guide on improving the battery life of the HTC One M8.
Let's be honest, this phone is getting quite old now. You can already start to feel it lagging, and slowing down. And the battery doesn't last as much as it once used to.
But don't give up hope...your M8 isn't dead yet, and with some good management it can even rival 2016 flagships.
Let's begin with Marshmallow...
If you have not updated your M8 to Android 6.0 yet, WHAT ARE YOU WAITING FOR?
Marshmallow is the best version of Android yet, the efficiency of Lollipop with the Stability of KitKat, and a very fresh take on Battery saving!
Reasons why you should update ASAP:
1 - Lollipop's memory leaks 99% fixed (Don't want to say 100% due to the possibility of some existing out of my limited knowledge, but for all intents and purposes there are no more memory leaks.) This is very important, because the memory leaks were both draining battery life, and slowing down the device...which in turn keeps the screen on longer and wastes even more battery.
2 - Doze!!! It's the latest battery saving feature to be added to Android, and it's basically a SUPER idle state, where the phone if left untouched with screen off for long periods of time will not waste any battery whatsoever! I tested this when going to sleep, phone was in airplane mode, battery saver turned on, screen brightness at minimum...I left it at 100% charge, I woke up it was still at 100%. With airplane mode off, and battery saver turned off the phone lost only 3% battery overnight.
This being said, true battery saving is measured while using the phone right?
It's not about how long it can last without being used, but how long it can last while being used.
But what if you already are on Marshmallow, and your battery life is still not cutting it?
The following solutions are organized from simpler to more complex.
1 - Follow this official HTC guide: Tips for extending battery life. It provides tips on reducing screen brightness, keeping connections off when you're not using them (Wi-Fi, Data, BT, GPS, NFC etc...), lowering volume and vibration strength and using power saver mode.
While their advice is quite obvious stuff, and most of you probably do it anyways, I would like to stress the use of power saver mode when you are out and about away from a convenient power source. Doesn't matter if your battery is at 90%, turn PS mode on, you will barely even feel a difference, but your battery will last you much more than before!
2 - Buy yourself a smartwatch. While it may seem counter-productive to keep Bluetooth on constantly to keep connected to the watch, it actually improves battery life by helping you avoid turning on your phone's screen. At the end of the day the battery saving that comes from it may be equivalent to the drain caused by bluetooth being on, or even greater than the drain. Thus effectively saving you battery life, and being convenient while doing it.
3 - Here comes the big one...ROOT your device and install a custom ROM and Kernel. Just by installing an optimized ROM and optimized Kernel you will get battery savings + better performance. Often you will also have settings you can tweak to optimize battery savings at the cost of performance or vice versa. And with a custom Kernel you can choose one with battery saving CPU governors.
4 - CPU Governors. CPUs, just after your screen, is the second most battery consuming hardware part in your device. Especially since it is on most of the time. Choosing a governor that can make it's job more efficient can save you bucket loads of battery.
The most common one for battery life is called "Conservative", and it will provide you with considerable battery life at the cost of performance. But if you want both good performance and good battery life then you are probably looking for a governor which employs the "Race to Idle" ideology. (If you don't know what it is, do a quick google, it's easy to understand.)
A good option I like to recommend is Wheatley, but if your kernel choice lacks it then interactive will be good enough...but you will have to tweak it's settings yourself to make it most efficient. Couple months ago I created this guide which you may find helpful when tweaking the interactive governor.
5 - Since we have spoken about Rooting then let's start adding some ROOT apps to the mix. Greenify would be my first recommendation.
For 2 main reasons... 1, It helps you stop annoying, battery draining apps which keep themselves running in the background. 2, It's latest versions have included a feature where you can set Doze to start sooner than default. Thus allowing you to reap Doze's benefits earlier and for longer.
Talking about the annoying apps, there's one in particular which comes to mind....Facebook.
Personally, while I don't like it's battery draining, I also don't want to uninstall it...since it's quite useful. Thus in Greenify I found my answer!
6 - Last but not least, if you are noticing unusual battery drainage, but you can't find which app is causing it (or may even be a system app), or if you notice that Doze is not having any effect... it might mean that a wakelock is not letting your device idle for long enough for Doze to start.
For this you will need an app called "Wakelock Detector". Charge your phone to around 80-100% and place it on a desk and let it idle for a couple hours (e.g. When you are asleep). When you are back check what WD found, and it might surprise you. (I found an app called HTC Mode which was keeping my device awake and preventing Doze from starting.)
Another advantage of this app is that once you find the wakelock it links you to Greenify through which you can put that specific app to sleep. Thus preventing it from setting the wakelock again.
If you follow all these steps, you should be able to feel the considerable difference in battery life. Reminding you why you fell in love with this device
I hope I have been of help, I noticed that there weren't any Battery Guides specifically made for the M8, so I thought I would leave one here in case anyone is looking for one!
If I have helped you make sure to hit that :good: button, I will greatly appreciate it, and you will be helping the community find this guide more easily.
Thanks for reading! Enjoy your longer lasting M8!
Thank you for the Info! Before marshmallow I used "app ops" but this doesn't work on Android M. Because of the app wakelock detector I removed the messenger app from facebook. It drained my battery. Thank you.

App ops is good for permissions, and stopping an app from connecting to the internet. Android M already has a permissions feature natively included.
What you want is to stop it from running in the background.
While you can uninstall it (and probably find another app which you can use facebook messenger in. e.g. Disa), I would personally recommend you simply use greenify to put it to sleep.
All official facebook apps are huge battery drainers, but greenify will keep them in check, so that you don't have to use another app with less functionality.
Obviously I am not forcing you lol, but it is my recommendation.

Rom battery life

Hi everyone, I'm a new user and I'm looking for a rom to help my phone with battery power. I was looking for an optimized and specific rom to optimize battery life. I can't post in the ROM section I hope you can help me.
Thank you so much.
Depending what stock firmware/software you're on rn, choose the right custom ROM, and then maybe use a custom kernel like ThunderStorm Kernel. Supposed to be a battery saver kernel, haven't tested just yet myself
Use a stock based ROM and a kernel that underckocks. AOSP and other ports will not be as efficient with battery in general. Lower clock speed generally improves battery life although keep "race to idle" in mind. Ur ROM and kernel are not the only things that affect battery life. Apps like nap time, Greenify, force doze, sysconfig patcher (for Magisk) can improve standby battery drain whilst having a dark mode/theme can help with screen on battery drain. Having better reception can improve battery life. If you don't use WiFi, Bluetooth or location then having them off can improve battery drain. Background apps/ bloatware can drain battery so limiting background apps/ removing bloat can help. Disabling notifications for apps u don't need them for can help. If u don't like using ur phone as a phone then I know alot of XDA members use airplane mode intermittently. This is just the tip of the iceberg and you'll need to comb through XDA to get more details. There are a few posts dedicated to battery saving too. Keep in mind that some of these strategies can affect functioning of your phone and it's all a balancing act between function and battery. My philosophy is to make my phone not waste any battery while still keeping all the functionality I use. Good luck.
