[TUTORIAL] How to prepair battery's for 3.0v kernels

Now that the kernel has been unlocked to alow the battery to use the full 4.2-3.0v potential, some people are having issues getting there battery to drain to 3.0 w/o having its protection circuitry kicking in.
Equipment
Multi meter- digita/ analog... doesnt matter, just need to be able to mesure DC voltage downt to atleat 1/10th volt.
Bulb -i personaly use a #194 automotive bulb
Procedure
drain battery as normal untill shutdown.
remove battery
check voltage across the 2 outer lugs ( just for referance )
take bulb, unfold the wire contacts so they stick out, touch them to the outer lugs ( bulb will barely glow its rated for 12v )
ether tape the bulb in place or hold it there ( i just hold it, keeps me from forgetting about it and draining it to low)
recheck votage every few min.
drain it to 2.9-3.0v
reinstall in phone and charge as normal
some batterys may require you to repete it to recondition the protection circuitry.
if you drain it below 2.5v you will need to buy a new battery... YOU HAVE BEEN WARNED!

Awsome thanks!! Do i need to do this everytime i reflash a eom or kernel thats is able to use this feature?

Li-io batterys need to be drained down every once in a while. Most experts recomend draining to 3.0v about every 30 cycles....

you will only break the battery by trying to drain to 2.5 or below.
3.0v is normal for a li-io battery.
this isnt new technology, were not doing any thing ground breaking. if anything were playing catchup. thank you samsung...

I am still a bit reluctant, however I am willing to proceed with more detail. If you can explain how exactly it works, it will make me feel more confident in doing so. I am not afraid at all in draining the battery with a bulb which I already picked up at Auto Zone, a 194 but this one is a 14v, all they had, and do know how to use a meter, ( am a low voltage installer, go ADT!)
So I was looking for more specifics. How does the kernel then register that the battery can now be used to 3v, etc... If you do know, if not that fine too
Just like to know how things work basically, and how it works.
Thanks!

Which kernels support 3.0v?

Look at eugene's a13 a14 and I think his new one too.

Well just drained the battery to 2.98v and put it on charge now. Cant get it to boot yet, even though after a minute of charging it was back at 3.3 v, Strange? ANyway Im going to let it charge some more and try to turn it on while its still plugged in.

So i have come to the conclusion that all thougj this does work to drain your battery the modded kernel does not work. I have not seen an increase in battery life at all. Which i am very dissapointed in.

Has Nothing to Do with the Kernel MOd... It's the Damn Kernel Clock cycles and sticking at high speeds when sleeping... I've said this many of time already & nobody listens..
OVERKILL Kernel was the First kernel that fixed this issue, so I'm not sure why you're disappointed? the issue was never fixed to start with until now, & even then you only saw a few hours at most with the 3.0V mod..
If it's Reading 3.30v then the Mod is working Correctly as by default it's set to 3.60V, in this case it's just a matter of dropping the Calculations for the battery down a bit more to get the 3.0v setting

Alright, finally someone who knows something about something
Well unfortunately I was unable to read through every post in the forum, but did not know of this issue. Thanks for dropping some knowledge that way I can reflash the new Kernel when I get home and, see better battery life, and watch some dragons.
Hope you didn't take my post the wrong way, by all means you are a legend among the this forum eugene and will always use your kernels, roms, etc.. With that said I might start my own thread to consolidate all of this battery questions, problems, answers etc. Thanks again eugene!!

All good man... I've just stated this a few already is all, lol....
But, with that being said, I know the Mod is working then, and I just need to do a few more adjustment to the source codec and fix a few Calculations to get us down more to the correct settings..
Thanks for Posting the 3.30V though, as this give more to go on, and I was waiting for true data reports before lowering it anymore to keep from brick batteries

Wrong Thread & no it's not needed with the Latest Kernel.

eugene,
So I just flashed the new Kernel, working flawless so far, but am at 60% battery, and have a voltage of 3700 mV. Not sure if that's where the voltage should be at that percentage. You wouldn't happen to have a chart, or know what voltage should be giving what battery percentage.
Should I try draining my battery again down to 3.ov since I just flashed the new kernel?
Thanks

It's based on the init of the battery Calculations.. So if the Calculations are wrong it will report odd until there fixed... Should be fixed in the Kernel I'm running though... Will be Posting the Kernel shortly & now is Marked Stable for all at this point...
Charts? lol, not unless I boot back into linux.. I'll get the charts Posted when I can so everyone can do reporting on it.

[MYTH] Wiping battery stats helps

There you have it, in the title. Google engineer Dianne Hackborn, who has previously explained Android’s hardware acceleration, took to Google+ again to clarify some myths about the Android operating system. This time, it’s a point of common advice that you’ll see in virtually every FAQ thread about custom ROMs and flashing: wiping battery stats in order to improve battery life.
The reasoning behind that piece of advice was something like this: If you, at some point, did not charge your Android device fully (for example, only to 80%), it would supposedly remember that battery level as “fully charged” – in this case, you’d only ever get to use 80% of your battery, which is of course less than optimal. So, if you wipe the battery stats, usually done in ClockWord Mod Recovery, the device would “forget” the previous level, here 80%, and instead charge to the full 100% once again, thereby re-calibrating the battery. Or, as Hackborn puts it in more technical terms:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
What’s more, you’ve probably noticed that the battery usage data is reset once you recharge your device anyway. From this you can correctly deduce that the battery stats are wiped as well – every time your device is recharged. More or less every day. If there was any effect, you would’ve noticed it without going into recovery and doing that stuff. Typical placebo, eh?

[MYTH] Wiping batt stats helps save battery life

Just because it makes sense, and comes from someone who should know, do you think we are going to believe it? =P
Just kidding. Thanks again!

Interesting, so why is it when I flash something and let's say my bat is @ 20% but after rebooting I'm down to 4%
Doesn't do that all the time but it is odd.

I saw that behavior on my previous Revo. Sounds like a good question to ask her.
I stopped "calibrating" the battery since that previous phone and have had no problems. Reading mtm say that he never calibrates with all he does with his phone, I am on that boat. Reading the quotes above is reassuring.

I have too and that's the whole reason I calibrate is because I thought it would give me more accurate readings. Plus, maybe I'm losing it, but I always feel like I get better battery life in the middle of the calibration process.

It's a volts/amps thing. The lower your battery is, the faster it will drain. Rebooting your phone takes a lot more energy for all the necessary operations during a boot up. Without going into detail, the amperage will pull voltage down faster on a curve as the battery level gets lower, just as it does when charging.
When charging, batteries will not only appear to charge faster for the first 40-50%, but they are because the charge voltage is much higher than the battery voltage, giving more force of energy movement. As the battery voltage increases, that force is less, therefore taking longer to push amps into the battery.
The reverse is in effect on draining. I would safely say that you likely wouldn't see that much of a percentage of change for a reboot when your battery was fully, or near full charged.
Hope that helps... I also see a major percentage drop when rebooting my phone with a battery at less than 40% charge left in it. If the battery is mostly charged, I don't notice much more than a percent or two drop.
If this isn't helpful enough and need a better explanation, just let me know and I will try to explain it better. It's just basic electricity 101.

@ cybie
Thanks for that bit of info, your explanation was very clear
Sent from my VS910 4G using Tapatalk

the battery drop seems to happen quite often when you flash a ROM mostly I have a question might sound dumb but since the phone is on and all systems are being active wouldnt that use more of your battery life

Damn you Hicks... next you are going to tell me unicorns aren't real.
Yesterday I was at 25% I reboot, and it warned me that I was at 15% upon starting up. I don't think it has anything to do with anything. The phone ran as though the life was still at 25% (an hour or so with heavy-ish usage.) If I have done a lot of rom-ing and theme-ing I will recalibrate (just as a reassurance to myself) I am sure it makes no difference, but it puts me at ease, and really being self centered... isn't that what life is all about?
Poor communication between the battery stat program, and the display program, could this be the thing that is driving everyone nuts? Maybe the two programs need a class to express their feelings better.

Lol sorry! I'm really not trying to be all "doom and gloom." Just thought it was an interesting find lol.

An Observation
Back in the day I had an Incredible. It was truly an incredible phone. With the exception of the battery of course. There were/are always two camps or schools of thoughts about the battery. One was that you have to "condition" your battery to get better life, the other was "F it, the battery is fine". There was also the "bump charge" mythos going around as well. I think, and this is just my opinion, this is the same thing as the wiping of battery stats every time you flash a ROM.
My experience, both on the Incredible, the Inc II, the Charge, Revo and Bionic, (some of these are my wife's phones) is that conditioning the battery, or wiping battery stats are just really, as Spc pointed out, a myth. Our batteries die faster when we flash a new ROM cuz we are playing with it more. We have a new toy again.. same with themes...or new kernels.
Every time I wipe my battery stats I end up with much worse battery life for several days.
But thank you Hicks for posting the article. Its always good to read a debunked myth!! Bravo!!
These opinions are mine and not intended to troll, or irritate or annoy people. If I do, sorry.

Not sure if anyone else has seen this....but i've found charging a little while longer after it says 100% seems to provide battery life.
If it take it off the charger right away...i get about 8-10hours. If i keep it on a few hours longer, i seem to get about 12.
I'm running at 1.2GHz...gVolt

Battery Monitor Widget mAh battery capacity indicator

You're probably familiar with Battery Monitor Widget. It's such a great tool, it can't go unnoticed in the Play Store...
Anyway. This app has got a nice feature called Calibration. It's actually a sub-program.
What this thing does is it estimates the miliamps (capacity) your phone's battery can hold, based on the logging the app does.
So, in order to find out what capacity your battery is able to hold (now, after some months of usage), you need to do this. Install Battery Monitor Widget from the Play Store, start it and :
1) Go to Settings - History and check all the boxes
2) Under History, set the "History update rate" to 10 minutes and the "History size" to 4MB
3) Under Monitoring, check "Monitor without widget"
And... that's pretty much all the settings you need to change in order to accomplish what I explained above.
Now, let your battery finish ~5 charging cycles (let it drain to 15%, then charge it back up to 100%), but with the phone turned on, not off!
I only did 2 charging cycles, and the app showed the same value it showed after 5 charging cycles... so... I'm not sure, but 5 charging cycles should be more than enough for the application to get a concrete read on the battery's capacity.
Now, when you're ready to find out... Enter Battery Monitor Widget app and, on the bottom, you'll see several tabs : History, Estimates, Calibration, Usage, Stats. Open Calibration and... see for yourself.
Post your results here. I'm curious to see whether this app reads the battery right or not, and, if it does get it right, how good your battery does after some usage. State for how long have you been using your phone and the capacity BMW reads. Even a screenshot, maybe .
----------
Oh... before some admin decides to close this thread because he thinks it's a duplicate of another thread... ask . You may not be right every time...

What do you really want to achieve with this? Now the thread no. 3 where you beg for test results by other members. But wouldn't your problem much easier be solved if you by a new battery?

Sure, it would be. But I don't really wanna give $20 away that easily. And also, perhaps the app doesn't read the battery's capacity correctly... which would imply my battery isn't dying, as I think.
Besides, perhaps you could be interested in your own battery's performance.
Now, sorry if my reach for help has disturbed you . You are not compelled to help me.

You do that!

Finished the first cycle (initial full charge after buying the battery > discharge to 9% > full charge) and got an estimation of 5607mAh and 22%.accuracy which seems somewhat right.
Here are some screenshots of BMW and battery usage from Settings.
http://db.tt/ZzHhl2OD
Update: the estimation keeps increasing as long as the phone is plugged in the AC charger, even though battery says it's full. It's 5737mAh now. % remains the same. Maybe because the battery is new and still calibrating itself or something.

Battery Life stinks and phone gets hot

My battery life is pretty terrible. Running stock, power saver, and Snapdragon battery guru. I have to charge the phone 2-3 times a day. I use in moderately to light through the day. At night, it will drain almost completely while I'm asleep. I had a Nexus 4 before and battery life was way better than this, same location, same apps, etc. I don't feel like I should need to turn data and wi-fi off to get more than 6 hours of virtually idle phone life from this device. Is this typical?
I find the phone is hot a lot too, when I am not even using it.

Please try to find out what causes this drain with the following app and post results after 1 unloading cycle

I downloaded it. Shut phone off and letting it charge, then going to see how fast it drains. To boot, its been on the charger for 2 hours and it has gone from 9% to 62%. Something must be wrong.

With stock my phone battery life sucked as well.that's why I rooted it and running a sense 5 Rom.. and it's so smooth I have my kernel UC to less than one gig speed and it still move fast without the overheat

Definitely not typical...
I'm fully stock and not rooted. If I dont touch my phone it can last over 24 hours with data on (noticed this one weekend when I was too busy to play with the phone).
I use the Battery Widget Reborn app and it says a "Fully charged battery usually lasts: 18 hours 8 minutes" for me.
Sounds like theres definitely some kind of app in the background thats draining your battery and making your phone hot.

This is pretty typical battery life for me with data always switched on on a rooted stock 4.2.2 rom and was also pretty much identical on an unrooted stock 4.1.2 rom.
The main thing that saves me a ton of battery life is disabling apps that I don't use. By far and away the Facebook app is a massive culprit for killing battery life.
I'm very interested to see the gsam results when you post them.

Well it's a definite improvement over the sort of battery life you were describing before. There are always ways of improving battery life but as has been said many times before it's all a case of where and how you use your phone that will be the main factor.

Battery life test

Can someone who actually has the phone post real world battery life test results with full res on, Bluetooth WiFi and GPS on, and without running YouTube to run down the battery.
I saw the video from the YouTube tech guy (thanks for all those btw), but these devices are optimized for video so running down the battery with a long Youtube playlist isnt "actual useage" if you know what I mean.

Yea a lot of people get the devices before the consumer release date to review them. Like this guy I know that it wont be "my usage", but I did stipulate a few conditions that would make it close to my use case and I wanted to make sure that streaming video on loop wasn't part of the test.

Understand completely.. i do not see the point in strategically getting high SoT or battery usage stats.. I just don't think it would help you someone else posting there usage for you to make a decision on. I assume you would be comparing it with your current phone with your usage

I've seen a video on YouTube that claims the screen on time is 6 hours and 45 minutes during normal use. That would be incredible

Found a great video on battery life

Seeing that video gives me hope. But seeing no updates to improve S8+ Is bull.

Just remember to look after your battery initially. When you first get your device charge it without using it. Once charged you'll be doing a lot of transfers and updates which will heat up the battery and device because of the load - I always do this initial set-up in a cool room or outside if cooler and without a case to keep the battery cool. Once set-up and you've played with it and the battery is drained, don't charge it . Switch off the device and let it cool down. Following this initial care procedure should give you better long term battery life.
