Many people have gone to sedio for more battery life out of the power sucking android phones to attempt to get the most that they can out of their phones, including myself.
Unfortunately, as seen in this thread: droidforums.net/forum/droid-accessories/9569-seidio-2600mah-extended-battery-77.html
extensive research has been put into the issues that the droid(and im assuming other devices)'s firmware was built to estimate battery for the original battery pack, and can not adjust when a larger pack from sedio(ranging between 1700 mah and 2800 mah) is put in.
There are also no apps to correctly read the batteries, with the closest thing to an accurate battery read is battery left which calibrates itself based off of mv and battery life, which is mediocre at best.
I know there are lots of dev's over here that are significantly smarter and better at modifying the system than most over there, and since alldroid is permanently gone as of now, I figured this would be the best resource for help.
Any dev willing to take on the project, there are many people in the listed thread with research in the project, but not the knowledge to fix the firmware, that im sure would not mind paying for an accurate read app.
I know this is an old topic, but there really hasn't been any advances on this and I am getting annoyed by my incorrect battery readings. Battery left does an OK job, but it still goes down to 1% way before it should, even though I have calibrated it over and over again.
What we need is a simple battery app that will let you define at what voltage your battery is at 100%, 90% etc.
Since it came up in the thread-that-shall-not-be-derailed, I thought I'd start a new one for discussion. That oft-asked question, "Do lithium ion batteries require break-in?" that I'd considered already answered (no, they don't), has been raised once again by none other than Asus themselves.
In the user guide, they suggest that the TF battery be fully charged (they say 8 hours, which seems crazy to me), then fully discharged/recharged a few times before the battery will attain its optimal usage. Now, I'd not usually be inclined to disagree with the manufacturer, but I've read enough about lithium ion batteries that says it's bad to do full discharges.
So, what's everyone planning to do? What Asus says, or what you normally do? Or both, if applicable.
For anybody who hasn't seen the manual yet, it can be found here:

heck even my laptop beeps wildly before reaching 5% so ill probably not doa full

Thanks for the links. I tend to do an initial full charge and rundown once out of habit (then many times throughout the life of the product since I fall asleep with it on ) The full 16 hour docked charge could make this a bit more interesting.
I will admit that I have not researched recent rumors that this is no longer necessary and any links on the subject would be greatly appreciated. (I will post my own as I find them.)

Ditto, and I've had no ill effect doing this with about 4-5 different notebooks, 6 or 8 different digital cameras / digital SLRs, several cell phones, and goodness knows how many other li-ion based products over the last decade. I always do at least 3 full cycles when I get the product, and then occasional full recharges throughout the remaining life.
I'll be doing it with my Transformer too, and probably would have even if it wasn't mentioned in the manual.

I do one cycle out of habit but no more purposefully for a full charge/drain.
I am apparently too new to link. So far I have been unable to find any primary sources, but the general information I have gleaned from blogs, wiki, and news articles amounts to:
-The battery in the tf101 is specifically Lithium Polymer.
-The battery does not have "memory" per se, so it is unnecessary to worry about letting it run down or charge fully during normal use.
--BUT, It is still recommended to do the first ~3 cycles of a battery as complete charge/discharges(down to ~5% is recommend in a few places). Charge to full first or it does some unspecified "bad" thing to the battery.
This is all from posts no earlier than 2010 and seems to still be the best practice. If anyone comes across a direct link to a research post or battery manufacturer site I would be grateful for a link. As it stands I am convinced enough to go through the process fully for the Transformer as a part of my first few weeks of use.
Keep in mind that this could be so that Honeycomb behaves optimally, not the battery itself. Similar steps are done after deleting the batterystats.bin file. It's not that the battery needs it, it's the software that interfaces with it that does.
Thanks for all the input. Sounds like while it may or may not be necessary to do a break-in like this, it wouldn't hurt. I'll just try to time mine so the recharges all happen overnight. With a 16-hour battery life, might take some planning.
Please post your battery life in stock marshmallow,stock nougut,RR,AICP and other roms.
So we can compare them.

There is really nothing one size fits all kind of thing. Try these different ROMs for yourself to see what works best for you. It's hard to see which has better battery life since different users will have different usage stats.
I have to agree... One person might get great battery on RR and terrible on AICP, the next person the opposite. The only to really tell which one gets the best battery in your situation is to try them.
Data is too scattered to determine which ROM provides the best battery life. You see people getting all day battery life with different kernels, tweaks, usage, etc

I'm not trying to bash your post but TBH, any comparison you make from others is practically useless. As mentioned, people have different experiences on custom ROMs. One specific ROM might have excellent battery life on one phone and have horrible battery life on another of the same model. But there is an even more important factor that makes comparing across ROMs just as useless... Everyone uses their phone differently. Not just with apps they install, but with the features of a ROM they they decide to enable or not.
On that note, if you are considering a custom ROM, the best way to determine if it is right for you is simply to try them. Make backups that way you can revert back to the one you decide is best.
I know that every user use their phone differently. I don't know what made you guys think i don't know that. But what i am trying to compare is not overall battery life but battery life based on individual usage. Like when some one use that rom for only calls and get a lot of stand by time how much battery it drains. from that i can know how much battery it drains when kept idle. Same goes for using wifi or using mobile data , watching YouTube or reading PDF. I want to know how much battery that rom uses on what usage.
Sorry for my bad English. I hope you guys can understand what i am trying to say.

I understand this. But I think it would be easier to try for yourself, because to get say, me to try say 4 different ROMs, same usage, and then report back to you would be more time consuming than you trying for yourself.
I know you know that every user is different but the same user trying different ROMs for you just doesn't make sense.

Referencing individual usage as you have, along with any specific ROM across devices, you are not going to get consistent results. I understand you are trying to consolidate this data on one post, but there are to many variables involved.
To highlight: I could run AICP on my XT1575 with a clean install and no extra apps installed and make only calls and I might get excellent battery life on standby. But another XT1575 owner can do the exact same setup, make the same number and times of calls and get horrible battery life. This pretty much goes for any custom ROM, especially those not based on stock. This does not even account for differences in MM vs N. This also does not account for an update to a ROM screwing up battery life and the next one may fix it (which is relatively common). I've even seen where someone gets great battery life up to a certain update and thereafter it sucks, but another can experience the opposite.
And once again, individual usage still matters as individuals will have different apps installed, which can take up varying amounts of battery depending on background processes and syncing. This affects standby time and SOT to some degree. Also do not forget that the chipset on this phone is prone to negative affects on battery depending on cell signal strength, so that is another kink in observing and comparing battery life across users.
Ultimately, the best way to determine what gives you the best battery life is too rest ROMs for yourself and your specific usages.

I am not saying anyone to try different roms for me. I was just wanting them to post battery stat of the rom they use as their daily driver.

Yes ok. So we should be on the same page about different users using their devices differently. So if user A posts about say ROM B, and user B posts about ROM A, you know you can't compare. I would post my stats with RR but you couldn't compare to someone posting AICP stats as we are different users. The only way to be even somewhat accurate would be to get the same user to try different ROMs. Which you can do. Honestly just try the different ROMs! I will say with my experience though DU has not had the greatest battery life.

Well said!
@yk1999 As stated above as well as in my post, you just can't compare experiences of users across multiple devices and ROMs as there are to many variables involved. We understand what you are asking and we are telling you that there is only one way for you to get the information you are looking for. The only way for you to figure out what will have the best battery life in YOUR situation (how a ROM operates on YOUR specific device, YOUR selection of apps, and YOUR specific usage scenarios) is to test the ROMs for yourself.
Maybe there should be an app saving battery stats for the current ROM (internal storage or personal cloud), and comparing these personal stats with previous stats made when you had another ROM installed.
Of course there are other variables that affect the battery stats (like the apps installed, or the apps you actually open in a battery cycle) but at least the app would be able to list and compare battery stats on the same device and user.
Ie, I imagine a list like:
- ROM R1. Kernel K1. X1 apps installed. Battery rate: BR1
- ROM R1. Kernel K2. X1 apps installed. Battery rate: BR2
- ROM R2. Kernel K1. X1 apps installed. Battery rate: BR3
...
It could be able to group by Android version,...
I haven't found an app doing this. Do you know an app doing it? And, do you think this app would make any sense?
Hello,
I dont really found centralized information about Oreo and feedbacks regarding battery life.
So please, people from Korea and North America, can you provide some feedback about Oreo update, especially about the battery life ?
I heard some negative opinion from this video : https://www.youtube.com/watch?v=m5hH0TQY6Jg
Before he was at 5-6h SoT, after update 3-4h
Thanks !
It was entirely predictable and expected that there would be no improvement in battery life or performance with Oreo despite all the anticipation.
I have literally NEVER seen a major operating system upgrade actually speed up performance of identical apps on the same device. Sometimes there might be a non-significant decline, but never an improvement.
Each Android upgrade promises some new trick to improve battery life like wakelocks etc, but it's only theoretical and perhaps applies only to brand new hardware.
Otherwise the progressive process of bloating in updated apps and system software use more power and more resources which more than compensate for the supposed improvements in efficiency
I think the few reports that have mentioned improvement are just the random variation that people get, even with Nougat, or even day to day on the same device.
Sometimes I get 1% standby drain per hour and sometimes 3% with no change in use or settings. I have found no consistent way to control this, including trying all of the tips mentioned (except for wiping my phone and starting from scratch).
So far the video reviews that I have seen of Oreo on the G6 are pointedly unexciting and confirm my predictions. As far as I am concerned the only reason to update is for the security patches. I am hesitant to update given that going backwards is difficult on a unrooted device.

maybe some little improvements are made, sure, nothing big to say its a major update, NO!
is almost only a Android version bump and a security patch. PERIOD...
The features this new version introduced is low and people who update the phone dont will see a big change, i already see some videos of update in youtube and didnt see too much difference.
Of course is a good thing LG doing it but isnt night and day,is more like some hours of difference.
Lets see with time to time the Doze mode and power savings features step in and see some change in battery life, i trust LG make something to improve it, again nothing special but for me that already make a difference.

2 remarks :
From my experience, I never saw an android update improve battery life too. But that was a long time ago, with "cheap" phones (expect nexus 4, so disappointed). But recently, a friend bought a Nokia 8, and after the Oreo update, the battery has become so amazing, I was really really suprised and so jealous! So now I still have a little hope ...
However concerning standby drain, for me it's pretty ok. In airplane mode lost 0 or 1% for all night, and with data or wifi, it stays "normal".
You guys have something else going on.like the first post said it depends on day to day and other factors like many apps running in back ground.My phone and battery have 0 issues.on full charge it stays at 100 for about 10min on heavy internet use and then drops about 2percent per hour.I only charge my phone every 3 days.I also found phone much faster after oreo and less studder.I suppose because part of the update is to have less apps running in background.I wouldnt really listen to some users because the change log for oreo is huge.Soooooo many changes under the hood.people should read the change log before giving false facts(and they are false)Always gonna have some dude complaing about something

Did you make some improvements like disabling logs and reducing resolution ? Any reset after oreo ?
I disabled event logs yes.kept screen on large size and no resolution change.Yes I did a factory reset immediately after.I think alot of people are having issues with battery because they dont calibrate it first when new out of the box.As a rule of thumb no matter what electronics i buy i always charge to 100 percent and literally let it drain to 0 percent then full chage again.Do this step twice in a row and i can pretty much guarantee you wont have issues with battery that are out of the ordinary.LOVE MY G6

I just got the upgrade on my g6+ batterie Went bad. .....I started to analyse battery usage and i found that chrome browser was one of the cause ..So i change it for Microsoft edge browser. ..now my battery is draining less. ....So i hope that did the trick. .......and i also cancel all other apps that i did not use

There are people that mainly use the phone under a wifi connection, and others that use it under a mobile network, this is just an example to give you an idea of why there is much difference between users
Y kllua but people are complaining regardless of wifi or mobile network. My package includes 6gb of network per month every month i spend 4gb etc...
And lots of people i see have bluetooth, nfc ( if they even thats in or what it even is. ) and then comes some1 like you and says ooo wifi on. What im gonna use at home ? Data ? To consump battery and empty my month data, and what im gonna use on streets, work, free time outside house etc. Mobile fking data. You think wifi is all around us

Well, my G6's battery sucks because at work the phone switches every couple of minutes to all the networks, and so I'm not able to reach home after 9-10 hours with 1-2 of SOT without charging a 20-30% during lunch, besides in weekends where I'm almost everyday under a wifi connection I easily reach 4-5 hours of SOT with gaming in a full day usage.
Also yes, there are many other parameters, like BT, NFC, GPS, Apps ecc...
So finally got Oreo thanks to LG Brigde.
The battery stock app seems really... broken ? Please see screenshots.
The message says : "2 days ago , 1h27min left the conversation."
PS : I made a factory reset after the oreo update.
Mine has actually improved! I'm getting like 30 minutes more (the improvement came after I drained the battery almost completely and charged it back like 3 times and after a factory reset). Not much but I can't complain. I'm actually happy for the improvements in fast charge speed, it's even faster now.
Third day with Oreo now.
Battery life is great, at least as good as before. I have 3.5h of screen on time right now and I'm at 43% battery at the end of a full work day with traveling etc.
And that's with Nova Launcher, Gesture Control [root], Always on Display and Pixel live wallpaper enabled.
Very happy with the G6 at the moment. Of course battery life always depends on your personal use and different phones provide better battery life for different people... G6 seems to work well for me and definitely better than the Huawei P9 I had before.
For people with battery life issues I suggest this: Battery life guide (I keep resolution at max because it messes with AOD and camera)
and also if you don't use google voice assistant try disabling the google app and use the chrome search widget instead. And keep location services on battery saving mode if you don't need GPS all the time.

Android 9.0 Pie incorporates a brand new feature: Adaptive Battery. It's an AI-powered feature that tracks your usage and limits your apps' activity, according to how often you open them. Some users report that you need a month of usage or so to calibrate the AI properly.
This feature has caused mixed reactions around the Android world, with some people claiming it definitely works, while others say it's just smoke and mirrors, and others saying that it actually reduces your battery life!
So the question is: Do you see a difference? Can you post some screenshots and comments so the Android community can finally have a definitive answer to end this debate?
