99% sure that this will increase your battery life

There are numerous threads about getting better battery life involving different settings, turning on and off stuff manually and battery calibration etc etc but noone that really helped as much as what ive discovered now.
Me and my spouse has the same phone but we dont have the same operator. I have Telia which has the best coverage in this area while she has Telenor which is worse in general coverage making the phone work harder in the net + really bad when it comes to 3G coverage and thus having slow data connection.
Therefore we have very different standby time on our phones and ive tried to tweak it with different kernels, modems and different flashes but nothing that really helped.
So I made a thread to gather some info from various people but it hasnt growed that much yet (http://forum.xda-developers.com/showthread.php?t=989266). 2nd post from "theduckking" showed that he was using an app called "tasker" which cost ~4euro (well worth the money if you have low battery time)
Now ive just started using it but I already have 69hours of standby and 27% left of battery and ive never had that amount of battery standby for a really long time! This is getting close to an old fashioned Nokia 3310 standby
My spouse isnt getting as much obvisually as she has worse coverage which drains more battery but she has gone from barely a day to 2 days standby with 10% battery left ~30hours and this is with the following method.
Note. Both our phones have the same configuration, its only the operator which is the difference
Rom: Darky 9.3 Final
Modem: JPY (its the one coming from the darky 9.3 flash)
Kernel: DamianGTO 1.1 Gold

Now two things that have made the battery last longer is first underclocking it to 800MHz and undervolt -100mV in CWM (this will only make a minor difference albeit noticeble)
And the grand thing that will really up your battery is the app called "TASKER".
Ive only setup two rules and that is to turn off mobile data and wifi when screen is off and turn them back on when screen is on. You can customize it further if you like but im just gonna show how to setup the basics.
After you have downloaded it, fire it up and press "new" and then just press "ok" select "event" and "display off", press "done"
Now press the "+" and "net" then "mobile data", make sure "Off" is selected and then press "Done".
Press "+" again and "net", "Wifi Net" check that it is saying "Disconnect" and press "Done" and press "Done" again to get back to the main menu of "Tasker"
Next rule so press "New" and "ok" again, then "event" and "Display" and select "Display On". Press "Done" and then press the "+" followed by "Net" and "Mobile Data", make sure the checkbox says "On" and press "Done" and you are set. Press home button to apply the settings and you should now have "Tasker" in the top row.
Now this fix will maybe not suit everyone but if you value battery time more than anything then its absolutely for you.
What will happen is that all data traffic will be completely turned off when the phones screen is off and the impact of this is
You wont recieve instant (push) gmail until you unlock your screen
Google talk will not let others see you online/busy when screen is off
If you are making calendar updates from google calendar online, the calendar updates wont appear until you unlock your screen
Probably other stuff that havent crossed my mind

Hoping this will help alot of you out there with mediocre battery

Some screenies from the battery status page in settings.
Sorry about the dark image, I raised the contrast and brightness manually afterwards to make it somewhat readable (I forgot to disable the "screen filter" which I enable at nights when reading )

pretty interesting.. will give it a try..

Hardcore made a thread on how to conserve battery life by disabling hsdpa. You can search for it. It has helped me a lot.

I'm using "superpower" from the market and I will install tasker to see if there is new options

If you use Tasker just for Wi-Fi and data turn - off when screen is off you better use (IMHO) SuperPower app. You also better untick auto retrieve option in MMS settings or you will not receive MMS anymore with this settings.

yay I'm famous... or at least useful
I have my connection Tasks attached to this post. you just have to import them and set up rules when to execute them. I have one that starts the OffOnScreenLock task when the screen is locked, one that calls the reconnect task when the screen is unlocked and one that does call reconnect every 45min
View attachment connectionTasks.zip
experiment with it^^
EDIT:
I also set tasker up to enable and disable GPS automatically (when maps or navigation start it enables GPS, on close it disables it again)
It's fun to play around^^

I using Super Power long time too (although i have 3000 mAh battery ), and i have battry life about 4-5 days on normal using, and 2-3 days by heavy using SGS.
I ask, after your testing, if you can make comparision battery life, using Super Power and Tasker, wich is better ?
Thank you in advance
Regards

Same here. Using Super Power some months ago, but now I'm curious about Tasker.
Wonder if it's better thar Super Power. Anyone can confirm that?

I just took a small look at super power. I found nothing you can't do with (except the 2g/3g toggling but I did not try that) tasker. The difference is, that you have to set up your own tasks and functions and rules. you can also create widgets and use variables to alter the way your own task works. If you have some programming skills you will probably love it, otherwise it's lots of potential left unused. (like loops, if/else statements)
You can read up on it over at lifehacker.com

I agree of course. Then again if you are a developer might as well completely roll your own
Tasker is nice if you know how to use it. Doesn't do all the things SuperPower can do, but can do a lot of thing (though less on 2.3, I think ? Not sure).
Gotta decide what's your own cup of tea. Apps like SuperPower (and Juice Defender, and a number of others ones) try to make your life easier, while with apps like Tasker (and the right plugins, of course) you can make your own rules. It's often more difficult than it sounds, though!

[ GUIDE ] Best ROM + KERNEL + SETTINGS combination for perfect battery life.

I recently bought the oneplus one and was a lot disappointed with the battery life! The max I got with many combination of ROMs and kernels was 3 hrs.
But finally after experimenting a lot, this is the best combination-
- Install stock cm11s ( Latest Version, in the screenshot ).
- Unlock the bootloader, root and install TWRP recovery.
- Install the latest franco kernel ( Latest Kitkat version, in the screenshot )
-Now in the settings go to PRIVACY -> PRIVACY GAURD -> Press the button in the top right and select SHOW BULIT-IN APPS -> Long press on GOOGLE PLAY SERVICES -> And now disable the options WAKE UP, KEEP AWAKE , AUTO START ( if available ) .
-Do the same for power hungry apps, for ex- Facebook.
-Switch off settings like Bluetooth and GPS when not in use ( Don't keep them on forever ).
-Try to keep brightness as low as possible ( Till the proper visible level, don't get addicted to brighter screens ).
The following activities had been done to produce the output in the screenshot given-
-From morning 9 to 2:15 till the next morning the whole battery lastet ( Till 4% )
- 4 GOT episodes were seen.
-2 hrs of continuous music.
-Heavy chatting all day.
-Heavy browsing of Facebook and instagram.
-Many you tube videos were seen.
-Wifi was kept on all the time.
-Average brightness was about to 20%.
The only bad thing is that you have to stay on lollipop only- Till now kit kat gives the best battery life. Do now update the phone, ignore/cancel the ota updates!
No bugs or so- Sometimes small bugs might irritate you ( Common in all android phones )
Questions/Suggestions all acceptable.

Best hack for battery life is keeping your phone in charge...

A trick to a long battery life.

We all know that the Z3+ battery is quite disappointing, it barely reaches 5:30 hours of SOT in best case scenario.
I've tried every little trick in the book, including modified kernels, different ROMs, underclocking CPU cores, and so on.
And all of these methods seemed to squeeze a max of 30 extra minutes of battery life, it isn't worth the trouble.
But finally, I managed to get 8 hours of SOT in my Xperia E6533, I'll share the method with you "Although it might seem a little basic, but this is the only method that actually made me get whole two extra hours of SOT".
----------------
What I did was:
- I started by doing a clean install of 32.2.A.5.11 ftf "By clean I mean I wiped everything, Userdata, Cache, everything"
- I flashed the stock kernel with TWRP included and DRM fixed "I'll include the kernel I modded using Serjar's rootkernel tool in another thread", I tried several other kernels, but for me, the stock one was most suitable.
- Installed Xposed and SuperSU from TWRP "Optional"
- Installed "Hide Stamina Mode Icon" Xposed module from Xposed Repository "Optional"
- I enabled Stamina Mode "Always"
- I went to Battery Optimization and ticked the apps that I want them to have internet access all the time "Even when the screen is off".
- Stamina Mode works like a charm in android M, Unlike android N, it doesn't seem to cause any lag, it only removed unnecessary animations.
- I went to about phone > Build number > 5 times > Developer mode.
- Removed any other animation from Developer mode like Transition, Window, and Animator duration.
- Went to Settings > More > Mobile Network.
- Changed preferred network type to WCDMA/GSM instead of LTE/WCDMA/GSM "Keep it on if you have an LTE connection"
- Went to my router settings > changed the channel bandwidth to 20MHZ instead of 20/40MHZ.
- Removed any third-party kill apps like greenify, etc, while I highly appreciate its effectiveness, Stamina mode seemed to work better on its own.
- Went to Settings > Display > Tap to wake up / Smart backlight control / Daydream / Image Enhancement > Disabled "Image enhancement really doesn't seem to make a noticeable difference".
- Removed weather widget.
- Disabled NFC "optional".
----------------
All of these basic and simple steps seemed to work better than the complicated ones, and thanks to them, I was able to get full 8 hours of normal SOT "Wifi, Facebook, Messenger, YouTube, Social Media, Movies" on my Xperia Z3+ "Screenshots in attachments"

Would this affect the camera quality since it uses Stamina?

I would like to charge the mobile twice rather to lose beauty of OS and carry a spare feature phone with loooooooong battery time for use in emergency.

Nokia 1208
Exactly. I too carry along a good old Nokia 1208 that I only use for GSM based services, and I only gotta charge it ONCE a week. Incredible! I use my Xperia Z3 heavily of course and that one is charged daily.

It's all about preferences, for me the beauty was never in these small animations, because I used to disable them from developer options anyway.

Not that I know of, I didn't spot any difference

Speed up performance

I've had my ZTE Axon 7 Mini for 2 months now moving from a Nexus 5 (I know long time coming) but I have been struggling with some performance bugs when unlocking the phone. I tried speeding up animations to get that little bit of performance boost (or an emulated one) and it didn't work. The solution that I ended up finding out is disabling the "Always show nav bar" switch under the Navigation Bar settings did I find performance reliability increase. Found this out the other day and just thought I would share to see if anyone had the same issue.

I've had mine for about 2 weeks (came from a broken S6). I had noticed some sluggishness and wondered how to improve it. I also did the animation tweaks but haven't noticed much of a difference. I've disabled this, it might be a bit faster now, I'll report back later.
Thanks for the suggestion
Robnw

So I can't say with any confidence that that tweak made any real difference. And I am sadly disappointed with the overall performance of my phone. There are lots of time when the phone is sluggish (easily 10 seconds to open an app) or worse (doesn't recognize or sense touches). Sigh.
Robnw

I just noticed a Power Manager setting - Smart power-save. It adjusts the CPU based on usage. I turned it off and now the phone appears to be more responsive. Hopefully this will make a significant difference.
Robnw

I got some but not much of an improvement by changing the smart power-save option. I still had some long touch delays (up to 30 seconds) and some long app starts (also up to 30 seconds). So I contacted ZTE USA and asked for help. They suggested the following:
1. clear the caches
1a. http://zte-iqorsupport.custhelp.com/app/answers/detail/a_id/1297
1b. http://zte-iqorsupport.custhelp.com/app/answers/detail/a_id/4685
2. soft reset - hold down the power button for 30 seconds (my phone restarted twice)
3. try safe mode - http://zte-iqorsupport.custhelp.com/app/answers/detail/a_id/4582
4. factory reset
I haven't yet cleared the caches but I did try the soft reset and what a difference it's made for me (though it's been less than a day so far). I wouldn't call this phone blazing fast but it's a night/day difference for me so far. I hope it lasts.

Miui battery management is sh*t

I really don't have any clue or solution on which Miui version I should flash to get decent battery life. No matter what version I use, (global, beta, miui 10/11) I always have high battery usage from one of these:
1. Cell standby (tried to switch network types, also through *#*#4636#"#* etc. without effect)
2. Whatsapp (this cr*p sometimes uses 60% of the battery, and I'm not even using it)
3. Android system (counts for most of the system processes and I get it but....)
I tried all kinds of battery optimizations, debloating through Adb etc.
Yesterday I flashed Havoc 2.9 and immediately my first cycle gave me 9:27 hrs of SOT on 4g, which I never managed to get before. I really like Miui, and I wanna use it, but have no idea what to do anymore.
Any suggestions of any kind?

I would say MIUI battery optimization is highly customizable. You just need to figure it out.
Go to Settings / Battery & Performance / App battery saver and click on Whatsaup choose "Restrict background activity"
Also you can go to Security app and click Manage apps from there you can see all apps and their permissions there block or restrict services you don't want to be running in the background unless you are using the app at the moment.
Other setting was in MIUI 10 "Start in background" but I don't see it anymore in MIUI 11 I guess it is removed for better battery life. If you are using MIUI 10 go to Permissions / Other Permissions and click on any app you will see the list of options including that the app can be run in the background automatically.

I tried all of the above, but whatsapp always eventually comes on top, including "cell standby". This was also the case on the Xiaomi Mi6, but on Poco it was all ok, it had phenomenal sot all the time
