I've been reading many complaints about the AOS bug, but everyone that complains of it refers to the percentage values. As I understand it, this is a relative value, and amounts to how much this process has run when compared to the rest (including the display-on time).
This means if you haven't switched on the display for most of the day, you might see the display using up 20% of the battery with AOS using 60% of the battery in comparison with the remainder spread among the rest of your apps. In reality, AOS might have run for 60 seconds while you've only run the display for 20 seconds as you booted up, looked at the time every now and then and nothing else.
Considering this percentage value will vary heavily from person to person based on usage, I propose we only compare actual CPU time used by the process.
Post the following 3 screen captures so that everyone can compare the real use of AOS and work out if it really is a bug for some and not others or if it is roughly the same for everyone:

Android OS cpu time
This is the most accurate way of measuring the extent of this problem to work out if it really exists or not.
i think there is a bug because on a nexus one, unplugged for 16 hours, Android OS only uses 5 minutes CPU time, equating to AOS of 2% usage.
compared to your 4 hours already used 12 minutes.
but it also depends on so many other usage factors its hard to compare accurately.
Etherous, I think you're part right, the percentage can be misleading, as if your phone does absolutely nothing else (theoretically), the Android OS would end up being 100%.
However, I also agree with RogerPodacter, in that it depends on many other usage factors.
Personally, I think the real issue is that too much is being labelled as "Android OS", and the real culprits of battery drainage are being masked. Trial & error is the only way to figure out what works best for you.

Noticed that as well..
14 hours, AOS used 50 minutes CPU for me.
don't know why
A lot of people complain of the AOS bug just by seeing high percentages indeed. However, the bug is real, and easily recognized. When it occurs, your screen shows "off", yet your "awake"-status is remaining on for long periods.
And of course thnx for warning people about the percentage-mistake, but it already has been mentioned in each topic tens of times ;-)

RogerPodacter, if we make the assumption that "Android OS" truly represents a collection of Operating System processes/services, then it would depend on those running in the background to keep the phone running. I would imagine the Nexus One is designed specifically for vanilla Android which means it maximizes the full potential of the basic software without the need for extra services to support the phone's hardware... this is why you can't just install it on, say, a Samsung Galaxy S2 which has more bells and whistles of a different nature (I dare say the hardware in the latter is far beyond the current native capabilities of 2.3.4 and is awaiting the arrival of 4.0 [ice cream sandwich] to reveal itself). "Android OS" is just that, it's the Operating System and *needs* to run to keep your phone alive.

lindsaytheflint, in continuing my thoughts from RogerPodacter, I agree with your statement that AOS usage really depends on what you actually want the phone to do inasmuch as it is what the manufacturer wants the phone to do. I believe manufacturers are pushing the current capabilities of the OS to its limits by pushing the capabilities of the hardware it runs on... that's the problem of having such an open design. In contrast, the iPhone is a closed development system with very exact specifications for its hardware that there is no need to chop and change kernel modules, seek different drivers, worry about various camera sensors focusing differently... It's a huge challenge for Android-centered manufacturers to make the current, limited software play nice. So you're right, there's a lot packed into the Android OS process, and different phones will report its usage differently depending on where your flavour of ROM is loading up its services.
With respect to the link, it makes sense that widgets (especially live updating ones) could lead to drain, and that could come down to how android deals with them, or even how android deals with them on a dual-core processor! Old MS Windows versions (and their legacy programs) had plenty of trouble handling certain functions on dual-core processors (even good-old hyperthreading) when they first came out.

kaassema, I noticed that others had mentioned the percentage-mistake, but I felt the need for it to have its own topic because the inconsistent reporting was driving me nuts, and that's why I believe it's important for people who say they have that bug to post those three pictures because one person's "light" usage could be another person's "heavy" usage and only a true indication can be followed in the numbers. Anyone keen on setting up a spreadsheet?
The fact that the phone's operating system runs while the phone is off can be attributed to a bug or simply a service that just has trouble finishing; that's why people/manufacturers keep chopping and changing different bits of code to make sure the phone does what you expect it to. Sure there might be an actual bug somewhere in one of the underlying services, or it might just be a very inefficient process that needs to be redeveloped because it doesn't play nicely with your phone/tablet's current hardware configuration. We can leave that up to the talented device-specific ROM developers to hunt for or just wait patiently for the ice cream sandwich release which is intended to have native support for all this wonderful hardware that currently exists... I feel like it's the Windows XP driver debacle repeating itself -- eventually there will be a stable-enough system that will run on any hardware with minimal tinkering.
I'm personally inclined to term the AOS issue as an incapability (instead of a bug) of the current Android version to run on far advanced hardware which has always been a problem in the computer industry... There are many angles to discuss this argument but they lay far outside the scope of this thread and I will not pursue them here
P.s , sorry for the long reply, you all had very valid points and wanted to address them all
Someone posted yesterday that the Android OS bug on his phone is due to his router .That router has problems with SGS2 so he says .
Is that another case of Android OS bug wrongly placed as the problem when its more likely the WiFi continually searching .
Problem is as posted screen broke = Android Bug . Everything and anything reported as Android OS bug .

Could just be the wifi service is also lumped under Android OS... makes sense to me.
I would hazard a guess that some might have a couple of internet-accessing widgets that constantly wake the phone to connect to wifi and update. That would drain a bit, too.
Someone who has the time could test if there's a significant difference between idling with or without a Wifi connection.
I installed Juice Defender, and set it to turn off data whenever my screen is off. It turns on by itself ever hour just to update.
This has helped a lot it seems. My Screen-on and awake are almost synchronized.

Hi,
Lets start this first, Im Dumb. Plain and simple. I know there are a lot of threads about batteries but its mostly people whining about it. All im looking to know is am i getting the right amount compared to some of you guys? and am i set up to even know how my battery is doing.
Im on the UCLE5 Goldie rom (Love IT).
i had a 20 minute phone call and thats it hadnt really used it since this morning. Took it off the charger. 20 min phone call, and about 3.5 hours later im at like 83%. Is that sound about right to you guys? I have chargers at my desk and in my car so im never far from power. But i would love to know how im doing.
Lets say that its not up to par. What steps should i take to maybe find out whats causing a problem should there be one? I have always read that task killer programs are actually not that big of a deal on the android platform.. im not sure if thats true or not but i have tried to research and it seems to be a consensus around it.
Please let me know what ya all think and thank you for all your help and patience in reading a topic i am sure you are all very tired of.

I'm on Electron73's UCLF5 stock ROM with a few mods and that seems about right.
I've found task killing apps to actually HURT my battery life. The reason is, everytime they kill a task that autostarts, it starts right back up. This uses processor power and, therefore, battery.
I would recommend trying out Battery Monitor Widget on the Play store. It's by 3C. There is a free version and a pro version. I used the free version for about a month and then bought the pro version. It will give you some great insight as far as your battery life goes.

Thanks JB!
Alright, so, no, that sounds TERRIBLE going from full to 83% in 4 hours with only a 20 minute phone call.
Im on stock, unrooted and (having just tested), I go from 100 to 96% after a 20 minute call.
So, one of three things are happening here.
1. Your phone isnt deep sleeping
Solution: cpuspy. There are instructions for how to set it up and use it, since I have never used it, I cant help you here.
2. Radios (GPS, Cellular Data, Wifi, Bluetooth, NFC)
Manually turn them off or use a tool to automate this. There are a number of them out there, Juice Defender, AutomateIt, or my personal choice, Tasker (listed in order of ease of use but least features/functionality to most difficult to use but has most features/functionality).
Personally, I dont think your radios would be the problem, but nonetheless, they are something that if you can control their use, can save you some battery.
3. Rogue apps
This is absolutely the most tricky one to figure out.
Option 1: Start by installing Titanium Backup from the market and do a backup of all USER apps (copy the backups to your PC before proceeding!!). Then you should do is a factory reset (Settings->Privacy), then install cpuspy, battery monitor widget pro (by 3C), and Titanium Backup from the market and use Titanium to restore only the bare minimum apps you need on your phone to survive (in other words, install only what you need, NOT what you might need). Slowly add apps (again, that you actually use) and monitor the phone. I usually will add 5 at a time, if I notice a significant battery drain after adding five, its easier to determine the potential cause.
Option 2: Now, since the above is an absolute *****, another option that might appeal is a little app called Autostarts. Launch it and as soon as it is done loading, hit your menu button and look for an option to 'Group by Application'. It might also not be a bad idea to enable the 'Hide System Apps' option unless you know what you are doing'. Once you have done this, start at the top of the list and disable EVERY condition that an app has listed under it unless one of the following is true:
1. The app has a widget THAT YOU USE (if you dont use the widget portion, then this is not applicable).
2. The app has a scheduled task to perform under certain conditions or at certain times (ie. podcast client that updates your RSS feeds at a scheduled time, or Juice Defender which disables services, Dropbox which might sync your pictures if you have it configured this way).
Be aggressive WITH USER APPS. Even apps like Google Maps have absolutely NO REASON to be running in the background.
I would NOT touch system apps unless you know what you are doing. Unfortunately, I am not familar with ICS on the Note and what apps it considers a system app, I was very delicate with these, only disabling things like Gallery, Maps (on the Captivate, Maps was considered a system app), & Music.
4. Non-updated apps
Lastly, I cannot tell you how stupid people are about updating their apps. Obviosuly, it isnt applicable to everyone but to give you an idea, my sister handed me her phone and it had 47 app updates. Just last night, I looked at one of our company phones and it had 33 app updates and a system update.
Samsung is SUPER terrible about linking their apps to the market correctly. Launch Titanium Backup and hit the menu button, under settings and I think More, you will find an option to link apps to the market (it might be called market doctor, I havent used TB in a long time). This will make a number of stock apps show up under your list of installed apps when you open the market and allow you to easily hit the update all button without having to manually search for every app you have installed on your phone manually, one by one.
App updates are extremely important, often times, security vulnerabilities and performance improvements are made (this might include battery life improvements). There are a number of ways to have your apps automatically update if you dont want to manually do it (me personally, I like to know what changes came to each app).
I also don't think my phone's battery is up to par with most of you on this forum.
I just bought an i717 from Telus and recently got the battery replaced because i was getting about 2-3 hours (which was unbelievable). So i got this new battery and tested it out for the past 2 weeks and as i'm writing this post, i'm currently sitting at 12% with 12h 7m on battery with only 1h 45m 'screen on' time. Screen is at the top of the list with 32% and Web second with only 12m CPU total.
Any of this sound strange to you guys? I constantly find my phone overheating when the display is on. I even have my radios being controlled with Easy Battery Saver and checked for partial wakelocks with the audio output being at the top.
Could it be my battery or do i have a faulty display?
Ok this is what i have done so far...
All apps were up to date
I turned off bluetooth.. GPS.. and Wifi (I did have these on all the time) and only turn those on when i need then
i used cpuspy and you are right it spends all its time at 380 mhz never going into deep sleep.
how do i determine what is keeping it from deep sleep?
@HVZY- What is your display setting at? Are you running gingerbread? How long have you had the phone for?

You can download Better Battery Stats from xda. This app will tell you what is giving you a wake lock. Really handy in finding what is keeping the phone awake.
First... Im new to this site and somewhat new to andriod
I recently purchased note 3 and i love what it can do...additionally, I purchased the gear 2 to match the phone. The problem is, I haven't switch phones yet due to some issues that im not liking.. Coming from an iphone 5s, I like the idea of having that freedom and not being tied down to apples controlling ways however, there may be some rhyme and reason to it?? Anyway, I bought the note 3 in hopes that I can break out of the iphone once and for all... but heres what im facing...
I have 3 email accounts configured on the device
Every time i click on message or I get an email notification, I click on it, it starts loading... the problem is, just to display the inbox takes about 30 seconds to load...once It loads the inbox, I can open the mail with no problem but I noticed a lag.. every time i i switch mail boxes
Battery life sucks!! brand new phone and the battery sucks and I can't figure out why!
The iphone 5s that I have, is really good on battery and i use it check emails on regular...especially my work emails (Exchange)...sometimes go on line check a few things and the phone can last me just about the whole work day without charging!!
I was hoping can do the same on the note 3 but unfortunately, thats not the case.. I've done a test and carried my both phones all day did just about the same tasks and i noticed a significant drop in battery, while the iphone does it effortlessly!
Now, im not hear to bad mouth the note 3... I really want to switch but these things are preventing me from activating the phone...
Everyone that I speak to that has the phone, are all experiencing long battery life and no issues like mine... so im turning to you guys to help me...
My last android phone was the EVO and i had to sell it because the battery life was soo bad, I was carrying two batteries and an extra charger just to prevent it from completely draining.. I had others suggest to me to turn off this and that...eventually my phones was as useless a flip phone. All that power that needs to be constantly charging... I cant have that.
I've even rooted the phone

Welcome back to the wonderful world of Android. My name is Topher and for the next 5 minutes or so, I'll be your guide to getting the most out of the Note 3. Sometimes, in order to help you, I'll need more information, so I'll ask questions. Since I end up writing very long responses, I'll try to bold all of my questions so they stand out more easily... I'm not internet-yelling at you in those instances.
Ok, introductions are now out of the way, let's try to get your phone working as you want it. I've grouped your questions/concerns into various groups so that we can address each one individually.
E-mail lag
You mentioned that you have a few different accounts, what e-mail services are you using? I ask because if all of the accounts are gmail, you can use the gmail app, which I find deals with the transitions a bit better than the original e-mail app that Samsung has.
If you have various services (yahoo, gmail, outlook, etc), a good option is CloudMagic. There are good reviews on the app and have gotten good reviews from blogs.
Another option (although probably less appealing) is using a distinct e-mail app for each service. Yahoo has an app, so does Outlook.
Battery Life
This is a big black box, since it's tough to say exactly what's causing it. I can typically get between 15-18 hours of battery life before I have to charge it up (I typically will charge when it drops below 30%). I've listed the various ways that I've seen that can help (or hurt) battery life below.
Signal Strength
For me, this is the number-one cause of battery drain. If I'm in an area with solid 4G signal, my battery life is great. It's a lot worse when I'm in areas where my phone is constantly switching between 4G and 3G (thanks a lot, Sprint!). The main cause is that, when searching, the phone boosts power to the radios and they just end up using more juice.
Also, having Bluetooth, GPS, and Wifi on (but not connected to anything) all the time will increase battery usage. These radios are regularly searching, so turning them off can help out.
One thing about Wifi, though... Being consistently connected to Wifi will significantly increase battery life, since you have a solid data connection and the phone doesn't need to search 4G and 3G bands as regularly in order to have service.
Screen Brightness
TThis is one item that is typically overlooked in terms of battery life. With high phone usage (games, internet, answering XDA questions), I've seen my battery drain 15% in under an hour when using high brightness. If I lower the brightness to half or lower, the battery drain is as low as 5% per hour.
Leaving the brightness on Auto is ok, but I've found that adjusting it myself is easier (I have a slide bar in the notification panel) and more effective in terms of battery life (you're not using an additional sensor to read the ambient light levels).
Rogue Apps
One cause of battery drain is wakelocks. Basically, when you're not using your phone, it's supposed to go to into "sleep mode," where the CPU and radios aren't drawing much power. A phone call, e-mail sync, or other things cause a wakelock and basically wake the phone up.
Rouge Apps are ones that cause a lot of wakelocks that eat up a lot of battery life. Once way to counter-act them is to find out which ones they are. Nowadays on Android, the battery info screen (Settings -> General -> Battery) gives good, detailed information on battery usage.

}
From this screen, obviously the fact that I had my screen on all the time is what caused the battery drain. I had it on full brightness, which didn't help. Also, during that time, I was checking out the various cat memes on Reddit, so that was also active and using up CPU strength and battery (but not nearly as much as the screen).
If you click on the graph, you get this screen:
This one shows the various system resources that were using up battery life (not associating them with apps). As you can see, there were times where I was driving through an area with little-to-no cell service (again, thanks Sprint). In those times, it's likely that my phone was using up more battery. But the biggest drain (when the graph really dips down) is when I have the screen on and when the phone is awake (obviously, those cat photos aren't going to view themselves!). If you see in your graph that there's a lot of battery drain when the screen is off, you might have a Rouge App causing a lot of wakelocks.
If you have a lot of wakelocks, you can find out which apps are causing them using an app like Better Battery Stats. This was developed mostly when the Android Battery screen gave little-to-no information, so you might not get as much additional info as you'd like, but it's a good app to keep in your back pocket when investigating wakelocks.
One way to quarantine rogue apps is to use Greenify (XDA link). It'll basically put those apps in a hibernation mode, which prevents them from waking the phone. It may break some functionality of the rogue app which rely on waking up the phone, but when the app is actively running (i.e. open on the screen), greenify doesn't touch it.
Hopefully these suggestions will get you started on your way to great battery life. There's one more thing I'd like to address, and that is ROMs.
Custom ROMs
You didn't explicitly state that you wanted to try out custom ROMs to solve your issues, but I'd be remiss if I didn't address them. In case you don't know what a custom ROM is, it's basically just a custom version of the phone OS which has been developed.
There are many great developers out here that create custom ROMs. Some focus on creating custom themed ROMs with tons of additional features, other focus on ROMs that strip out all of the extra TouchWiz bloatware that Samsung (and Sprint) add onto the phone. Some developers focus on maximizing battery life, while others focus on making a "stock android" (AOSP) experience. Finding the right ROM for you
I'd recommend browsing through the various ROMs in the Development Section of the forum. If you read the posts, various users will give their battery life using that particular ROM (as it's important to most of us here).
In Closing
If you've read this far, congratulations! I can't believe you actually read the entirety of this giant post I made. Kudos!
Anyways, if you have any more questions, just reply to this post and I'll try to answer them as much as I can.
I hope this helps!

aol.com
gmail
and exchange
now I managed to speed up the e-mails by simply removing them all and adding them back again. this process took along time as well as some battery life. you mentioned that you can get 15 - 18 hours of battery life without charging... That is awesome and I honestly can't get that with my iphone.. but I can get at least a full day while im at work which is 8 hours. I'll be happy that I can get a full days charge without having to worry about plugging in the phone. This is another reason why its hard for me to part with the iphone.. I've come to terms with my podcast and I already
At the time of this response.... My iPhone has been keep good charge at 83% since i left the house this more at 8:30 am. However, when I got into work, I decided to turn on the my note 3 and occasionally checked my emails at around 11 am. As of the response, my battery life has been at 65% and that's heavy use... so im suspecting that I have, what i like to describe as crap-ware running in the background. I feel that once I have my note running solid with the battery life lasting and I don't have to worry about it, I will switch with no hesitation.
The reason why im so particular, its because I use my phone for emails especially for work. So I have to be in constant contact. This reminds me of an old commercial that saw before with a guy showing his exotic sports car at a gas station, as he reved his up to show up, his gas tank would empty out... Thats how i feel about the note 3, I have fancy phone but im afraid to use because im afraid that I will use use up my battery before I even get home.
Yes, you are right, the iphone requires little to now tweaking.. which is my case but of course im restricted unless I jailbreak the phone..
You mentioned roms... Unfortunately, I am completely new to this and have no clue how it works except on emulators for games... So i need help on this... I have the basic understanding of rooting and I was able to do it on the note 3, so i can safely say, my phone is rooted.
I'm desperately looking to switch..... I just want to perform well and keep a good battery life.
My wife's s5... works excellent right out of the box.
Outstanding....
Outstanding input, @topherk. I think this is useful advice from which many could benefit.
Much appreciated.

I'm glad that re-adding the accounts worked. I hadn't even thought of that, and it seems to be a common solutions when issues arise within the default e-mail app. I wouldn't be able to tell you why that happens, though.
One thing that I forgot to mention that could affect battery life is the frequency of checking the accounts. In the Email App, under each Account's settings, you can adjust the frequency of the syncs. Unless I'm mistaken, I think that "push" notifications is the most economical in terms of battery life, but it might not be offered for each type of account (I tested it with my gmail and it was able to do the push notifications... I don't have a Yahoo, AOL, or hotmail account. Below is what mine shows.

In my opinion, running a custom ROM is the best way to increase battery life. Most Devs on here use tweaks and mods in their ROMs that extend battery life substantially. I won't link you to a specific one, but if you choose to install one, I can definitely help with that.
Now I'll explain how to install a custom ROM and some common things to think about/check prior to installing anything:
Installing a Custom ROM
Step 1 - Gather Information
First off, you need to know what version of Android your phone currently is running. This is easily done by looking in the Settings Menu -> General -> About Device.
The Main things we are looking at on this screen are Software Version, Model Number, Android Version, and Baseband Version. I'll explain these (to the best of my knowledge) below:
Software Version:
This is the "type" of Android that you're running. Rather than quoting the entire name, we typically only refer to the last 3 characters (MJ4, NAB, NC5, etc.). Stock Note 3 devices will (most-likely) be running one of 3 different versions of TouchWiz (TW):
MJ4 - This is the last Jellybean version of TW for the Sprint Note 3NAB - This is the first KitKat TW version for the Sprint Note 3NC5 - This is the latest KitKat TW version for the Sprint Note 3
The reason that we are concerned with the Software Version is that between the MJ4 and NAB versions, there were major changes. So if you're running MJ4, you will have to do additional steps before flashing a custom ROM based on a newer version. And if you're on NAB or NC5, you will not be able to go back to MJ4, so beware what you're flashing.
For the most part, if you're on NC5, you can flash either a NAB or NC5 custom ROM, but just read the ROM's FAQ to see if there are any issues with doing so.
Model Number:
Most people don't worry about this, but I always do when looking at a new ROM. The Sprint Note 3 is different from the Verizon Note 3, which is also different from the International Note 3. It's always best to double-check that the ROM you're trying to install is truly meant for your device. This simple check will prevent a LOT of potential issues you'll get when installing a ROM.
Android Version:
This is just an additional check to the Software Version. Always best to know.
Baseband Version:
The Baseband is, unless I'm mistaken, the "kernal" for the phone's cellular and 4G radios. Sometimes upgrading (or downgrading) the Baseband can help with signal strength and reception.Some users have noted that they got better reception on older Baseband versions. I haven't personally looked into it and the reports from other users seem somewhat anecdotal, but it's good to know which Baseband you're on.
The Baseband is independent from the ROM version, so you can run an older Baseband (MJ4 or NAB) on a newer ROM (NC5), and vice-versa.
The last bit of information you need to know is the Bootloader Version. The way to find this information is to reboot your device. When you see the text on the screen, you should look for the Bootloader Version. It'll be a long string of characters, but you're only looking for the last 3 (MJ4, NAB, or NC5).
Once you have all the above information, you should be ready to start the fun process of preparing your phone to flash your first ROM.
Step 2 - Backup your Media
First thing: Backup all of your media to your computer. If there's pictures/music/videos/recordings you don't want to lose, back them up. It's just good practice. Don't lose all your cat pictures because you flashed something and it somehow erased your internal storage. I tend to keep everything of importance on the External Storage, but there are times where even external storage can be wiped, so it's best to back up everything to a PC.
Step 3 - Upgrade your Phone to the latest Stock ROM (NC5)
This only is a MUST applies if you're running MJ4 and want to install a NAB or NC5 ROM. Most continually-developed ROMs are either NAB or NC5 now, so the first things first: Update your phone to NC5.
Go over to RWilco's thread and download the One-Click File. It will remove Root, but don't worry, because when you install a new ROM, it will automatically include root access.
Follow the instructions in his thread and your phone will now be fully upgraded.
At this point, your "About Device" should show the following:
Software Version: N900PVPUCNC5
Android Version: 4.4.2
Baseband Version: N900PVPUCNC5
Reboot your phone and let it sit for a minute so it can get it's bearings.
Step 4 - Install the Engineering Bootloader
I recommend installing the Engineering Bootloader. The major reason to install the engineering bootloader is that it allows you to flash different BaseBands (modems). And you never know when you might need to do that.
Just go to the linked thread above and flash it in ODIN. It should go in the "Bootloader" slot in ODIN, not the PDA slot.
Step 5 - Install a Custom Recovery
So far, we've been flashing everything in ODIN. Now, we're going to use ODIN one last time to flash a custom recovery, so that you can flash custom ROMs without the need of a computer.
The most-commonly used Custom Recovery is TWRP (XDA Link). You'll want to use the latest version, 2.7.0.1.
Flash this in ODIN. I believe you use the "PDA" Slot.
Reboot your phone to make sure it works correctly.
Step 6 - Make a Nandroid Backup of your device
If you don't know what a Nandroid backup is, don't worry. It's basically just taking your phone as is and making a backup of it. In case you make a mistake or flash a bad download of a ROM, this allows you to restore your system. I always keep my backups on the External Storage (microSD Card), so in case I have to wipe my internal storage, it's not a big deal. You can also copy the files over to your PC, just to be more paranoind about your nandroid backups (rhyming is fun!).
You do this by restarting into Recovery (power down device, hold down home button and volume up while powering on phone).
Once in TWRP, go to "backup." Make sure the storage selected is "external storage." This screen will have various options of what to backup. I typically choose everything except external storage. Typically, backups range from 1-2 Gigs.
For me, backups typically take 5-10 minutes to do. In my opinion, this is totally worth it, since I can always restore a backup with no issues.
Step 7 - Install a Custom ROM
Once you choose your custom ROM from the Development Section, follow the instructions on the original post to install it. I'll give a general outline of what I do whenever installing a new ROM, but sometimes a custom ROM will have specific instructions, so you want to make sure to read the posts carefully.
Generic Instructions for Installing a ROM:
Download ROM and check the md5
Internet being spotty in my area, I always check the md5 to make sure that the file downloaded correctly. You can check the md5 using this windows program or using a file explorer on your phone like ES File Explorer. I always copy the ROM zip file to my external SDcard.
Reboot to Recovery
Wipe Data, System, Cache, and Dalvik Cache
This is called a "Clean Wipe," meaning it will wipe out your installed Apps and the data associated with them. Some people will claim that "Dirty Flashing" (i.e. not wiping the above) is OK, but I've seen too many apps Force Closing (FC-ing) when dirty flashing. Also, if you dirty-flash and encounter an issue with a ROM, the first piece of advice is to do a clean install. Might as well do that initially and hopefully not run into any issues.
Install the Custom ROM
Pretty straight-forward on how to do this... just click "Install" and then browse to the place your copied the ROM zip file.
Reboot your phone and run through the typical initial start-up information (google account, etc).
Once you get your phone set up the way you like (apps, accounts, wifi passwords, etc), I'd make another Nandroid backup, just so you have one where it's setup with everything you need. This will make any issues less painful, since you'd restore a backup that's already setup.
Step 8 - Further Considerations
If you ever want to try a new ROM, all you have to do is repeat step 7. Beware, though, people easily become flashaholics when they first figure this stuff out.
If you were paying attention to my "Generic Instructions" when installing a ROM, you'd notice that every time you do a Clean Install of a ROM, you lose all your apps... All of your Angry Birds 3-Star levels are gone!
Well, there are ways to get prevent losing that data... One is by "Dirty Flashing" (Not wiping the "system" or "data" partitions before flashing a ROM in TWRP). This is common practice among users here on XDA, but is typically frowned upon by ROM devs. I've noticed that a good number of issues on ROM threads stem from people Dirty Flashing. It typically causes more problems than it solves.
The other way of backup up and restoring app data (prior to wiping) is by using Titanium Backup. I could write up a long post on how to use Titanium Backup (TiBu), but the main things to remember are the following:
White line items are fine to be restored (both Data and Apps).
Restoring Yellow line items is typically OK (Data only).
Restoring system apps or data (red line items in TiBu) is typically a bad idea.
I've been using TiBu for the past 2-3 years and it's typically worked like a charm. Sometimes, when there's a major Android Update (like from JellyBean to KitKat), it can become broken, but the Developer is really responsive and gets it to work within a few weeks. If you upgrade to PRO, you can schedule automatic app backups (I backup all my user apps every night at 3am). You can also restore apps/data from Nandroid Backups (which is great if you do a Nandroid backup but had forgotten to update your TiBu backups).
In Summary
Whew, that was a lot to write... I'm a Structural Engineer, not a Software Engineer, so I don't know the technical side of things like bootloaders or basebands, but hopefully none of the information I provided was false.
Anyways, let me know if you have any problems with the install. I appreciate any feedback!
Was hoping that 7.1.2 was going to fix the battery issues. Alas Android OS remains #1 or #2 battery drain item even after the most recent update. Going back the Marshmallow. Google should study the hippocratic oath - first do no harm.
Just use pure Nexus. I get 4-5hrs SOT on LTE. I use whatsapp, snapchat, facebook, twitter. Just make sure you disable location services, else Google play services will eat up your battery fast
Does anyone else get like 5 hours SoT and good standby time as well even though Android OS is at the top of the list? I feel like sometimes this "issue" is massively over exaggerated...

Nougat calculates battery differently then MM. It's even better at measuring.
I have better battery on N then MM.
This is why I'm excited for android O, to see if they actually do what they're saying about stopping apps from being able to run rampant in the background. My iPhone will not even lose a single percent overnight while I'm sleeping. My 6p drops 10-15%. I'm getting pretty tired of having to manage my phone to be honest. For a smartphone, it isn't very smart.

There is something severely wrong with your setup. I lose 0.1% idle, overnight. 10-15% is way too much and I guarantee it's not the Android OS which is causing it. Something else which may be reported under Android OS in battery settings, but 15% is not normal lol. That's on your end 100%

.1 lol sure..
So using a phone normally makes it my fault? Interesting. As I said, I don't want to manage my phone. I shouldn't have to worry about what rogue apps are draining my battery. It shouldn't be so inconsistent. If anything you're making my point for me, and placing the blame on a user for using the phone as a phone and not installing stuff like greenify and naptime, expecting them to micromanage what the os should be doing in the first place is both hilarious and sad.

Well according to both AccuBattery and EXKM battery monitor yes 0.1 percent. I'll charge it again today and leave it overnight to show you my idle drain. No biggie. Something you have installed is keeping your phone awake, point blank period. I don't use greenify or naptime or anything. Never even heard of the latter...

Also, wakelock detector and better battery stats can't give me a clue what it is other than "Android os". I've been at this too long, since 2008, and really I'm just at my wits end. I want something I can use and let do its thing. I don't have time to be doing the work the os needs to do itself

I have two apps, as I stated. Maybe you're fine with doing legwork for the os, but after about 9 years of doing so I just don't want to anymore.
You can argue about it all you want, but being a closed minded fanboy and refusing to even think about what I'm saying is going to harm Android if anything. They know it's a problem themselves

Android OS is 15% of my battery consumption. Google Play Services is another 15%. Android System is 12%, screen is 11%. This does not sound right any way you cut it. I have tried greenifying every app that I don't need to be updating in the background, there is little difference. I don't use Facebook and WhatsApp, but I do use Gmail and MailCal quite a bit. Not much SMS either.

I deleted them and wanted to run android without tweaking it. A lot of my reasoning was to see what it was like to just run it as is.
The point is, the average user does not root or tweak their phone. They expect it just to work. I can't count the number of times people at work have gotten me to help with their phones since it was draining in a few hours while not even being used. I'm glad they are trying to attack this issue, for most people, this is the downfall of android.
I have tried every kernel on here, and while I did get better battery life with greenify and other things installed, it seems like after this long it shouldn't even be necessary for the user to be occupied with that stuff. A phone is supposed to be a tool, you shouldn't need to disable settings, freeze apps, and everything else just to have it work how it should in the first place.
Honestly... it all depends on the user. I've read through the comments, and like you, people ask me for help with their phones as well. Majority of the people I'm surrounded by are always on their phones,max brightness,etc, so it's normal for their battery to drain as fast as it is. I'm at 20% battery right now, with 3h 30m SoT and I have 232 apps installed. I don't do battery tweaks, and I use the full package GApps package(Aroma) only not using Google Photos and all the other language keyboard related stuff. I'm a heavy texter and audiophile (V4Arise is installed).

This is interesting about losing that much battery over night. I'll charge it up tonight and see what I get because I thought the battery issue would change with the update.

What app would you use to pinpoint the wake lock to see which app is rouge?
A troublesome bug that causes the drain (discharge at high speed of the battery) of the MI8 is caused by the voice Mobile standby, in fact if you go in the battery settings, you will notice a high% of consumption of the item in question.
This is caused because, by default in the Xiaomi rom (China or global) is also the search for frequencies also Chinese, this involves an intensive use of the network module that continues in a way to find these Chinese frequencies, which of course in our country , just as all EU countries do not exist, leading to greater use of autonomy.
Xiaomi is already aware of the problem and will certainly be resolved, when it is not known.
In the meantime, you can solve the problem by yourself, as follows:
Enter the following USSD code *#*#4636#*#* in the dialer.
Set the LTE / WCDMA mode to both SIMs
In this way, only the European frequencies will be used, eliminating the battery drain.
You're welcome btw

It's also a pretty old bug, somebody else had the same idea 4 months ago:

I agree with you, I really do.
But even if you searched about the device you want to buy even for months before getting it you'll see there is absolutely no device existing without at least 2-3 issues out there.
Even pixels which are what android is and more than that, have problems.
You either bear with it, or stop using smartphones.
And the second option is not a viable choice for me.
P. S. Got a poco before the Mi 8 and refunded it because of the touch lag, I know that Xiaomi doesn't test enough, be it software or hardware.

I really respect what you say and most likely you are right but what now? You see I am using the phone professionally and battery is crucial for me.
Thanks for the advice. There is battery drain with V10.1.2.0. Cell standby. BTW, you can reach the menu by repeatedly tapping on "Internal Storage" in the "My device" settings. There are some "secret" links in settings.

If this bothers you that much then either flash a custom rom on it, or refund/sell the device and get something else, maybe an OP6T.
I ran a little test today to find out if other devices handle it better and it does appear to be so. Mido battery drain with LTE/WCDMA and LTE/TD-SCDMA/UMTS was exactly the same.

But the cell signal history wasn't...
Redmi Note 4X, Xiaomi.eu 9.5, 70km Highway drive with Waze and internet music stream running, fixed display brightness. Same route in both tests, just opposite directions - hence me flipping 2nd signal history in the following screenshot:
I ran a similiar test on my MI 8 a week ago and there were massive differences in battery drain and signal history...like I said I think MI 8 has a baseband issue that somehow can get amplified by the MIUI default network mode setting.
well i seen someone said that global beta 8.12.20 it is way better.anyone tried it around here?i was thinking of trying it myself actually...i think i'll do and came back with some feedback.
idk I've been on global beta since 10.0.3.0 global stable release and I've had all of these issues. It's possible that android 9 adaptive battery feature in beta 8.12.20 helps a bit.
Make sure non interactive scenes are disabled in settings \ battery \ scenes
I have the same problem, my drain was 40% in 8 h in standby mode. I flash my phone to miui 9 and then i update to miui 10 - 10.3.3 global, then i clean al my programs and i don't update sistem apps from Xiaomi. At last i turn off my phone and i charge up to 100%. Now my drain battery per night is 5-6% and last almost 2 days?. Good luck!
I was handed an old Touchpad to see if I could get it working for my kids' learning apps. We're in quarantine from the Corona virus here in upstate NY and it looks like I won't have an income for a while, so I'd like to see if I could make this work.
The previous owner doesn't recall what he did, but I'm greeted with this menu upon boot:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The Lineage option boots into a Nougat 7.1 that is SUPER LAGGY. Like, I went open a blank browser (no tabs open), and it sometimes can take 30 seconds for the keyboard to appear. And pressing the circle home button can take 5-10 seconds to respond as well. Other times apps just won't load unless I reboot first. It makes using any kind of interactive learning game downright impossible. The evervolv option straight up doesn't work. I'm not even sure why it is there and the previous owner doesn't remember why it is there or how it got there either.
I'm thinking I should just start with a different rom. But I'm not clear on how this dual-boot setup works or if I'll mess something up just flashing in twrp. Like, if I flash a rom in twrp, which partition will it be flashing to? And for that matter, how do I remove one that doesn't work? I'm new to touchpad in general. Someone suggested just going back to stock WebOS and starting over from there but that seems like more unnecessary work if I already have twrp installed and running, right? Suggestions?
So do you know your way around how to reset and install a new Rom using J.C. Sullin's TouchPad Toolbox?
I would suggest reading up on using TPTB. Download the required files and install his Rom, CM11. It was the best, most stable and functional Rom made for the TouchPad. Even the camera works. I know you want to set it up for your kids and I think you will have the best luck with Sullin's CM11. I've seen you trying to use the method by HPTouchPad and are having problems with it. If you ask him about my suggestions, you will find out he had a white hot hate for me because I have questioned and challenged him ever since he started that and several other threads. He claims everything he creates works perfectly when in fact it doesn't. His method is interesting, but if you question anything he says, he goes out of his way to attack and cast dispersion's on you.
If you get your TP setup and can download the apps you want for your kid to use and working OK, I'll tell you about what I did on two TP's I own that I feel gets me the best performance and stability. You may even be happy enough with CM11 that you won't even want to mess with my idea. Just remember, if HPTouchPad finds out you are talking to me, he will probably go ballistic.
If you have the time, read thru that thread and you will see what I am talking about. If you notice towards the end that he is starting to waver on what he suggests you should install. Earlier in the thread, he claims that you can load and run anything including the Super version of Gapps which is huge. And any of the various Roms he has modified and tweaked. It's nothing wrong with his work, it's all the fault of Gapps, ads and weather apps. Oh, and you absolutely must keep your TP charging at all times, that's because his stuff just drains the battery quickly. Note, TouchPads do not like to have the battery drained down to low levels or to the point where the tablet automatically shuts down. It's a proven fact that could cause problems on the TP, so you want to keep an eye on the battery level and I recommend not letting it go below 20%.
With Sullin's CM11, I can leave my tables off charge and when asleep, will last for days. Good Luck and stay away from that nasty virus.

Depending what you intend to do with the touchpad each person has their own opinion about what works for them. I found the following combination works best for my 16gb tablet. I use it for youtube, hulu, and surfing the web. I also have this on my 32gb one but it's got some games for the kids. The battery drain thing is a problem but not a major issue for me. Only thing that annoys me is if the battery is too drained to get it to boot up. I have to hold the power and the home key (I think) to get it to boot up otherwise plugging it in does do a thing.

@dizzymon Your are an example of how a discarded old device found on an ewaste bin was brought back to be useful again, thanks to all the hard work of many developers that dedicated their time to port Android to the HP Touchpad:
From your post dated December 6 of 2019:
https://forum.xda-developers.com/showpost.php?p=81116701&postcount=183
""My 32GB runs pretty good but my 16GB one that I found in the ewaste bin at work runs like garbage. I will toss it soon."
The Tablet enhance performance with my Kernel settings provided to all the ROM are as follow:
Makes the Tablet run like a Desktop computer or a Laptop: ( not like phone or a mobile device )
A swap partition ( provides the use of more memory )
Remove all the power restrictions to slow the CPU to maximize battery.
Make the CPU works at it's highest frequency only when need it and be stable.
Allocate the full 1 GB of RAM ( HPT_MaXtreme Kernel only )
This is the universal rule that applies to anything.
( More power or energy = faster speed )
( Less power or energy = slower speed )
Regarding the battery drain:
The Tablet is extremely optimize for streaming media:
The original ROM stocks provide no more than 2 MB of buffer, with my Kernel settings is 6 MB of buffer and can be setup even higher!
With my kernel settings the Tablet can stream HD 1080 24/7 with no issues.
That extra Power means more electricity, there is no way around it and the reason that I always say keep the Tablet charging at all time, even while streaming if allows.
To really know the health condition ( capacity ) of the battery do the following:
open a command prompt or terminal on a PC with the novacom driver an enter:
novacom -t open tty://
then
battery status
Example:
[email protected]:~$ novacom -t open tty://
battery status
battery present
voltage: 4113840
percentage: 100
current: -861562
capacity: 6483200
] a6 version
The capacity is the true battery energy :
