[Tutorial]Battery Recalibration

Though Most of you Might know this already But I'll post it for the new Users out there
So you have flashed your Rom Recently and are finding some trouble with your battery?
Does it dies too quickly? or you see those numbers going down very Soon?
There might be some Other Issues related to Battery drainage but most common problem the user might experience after flashing quite a few ROM's is Mis- callibration of the battery
To fix this install a market app known as battery callibration
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
You need to have a ROOTED device for that
program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
When you reboot the phone after calibration a new batterystats.bin is created
IMPORTANT after calibration let your phone discharge to 0% and then charge it to 100% without break
DO IT AT YOUR OWN RISK (although None is involved) I'm NOT RESPONSIBLE FOR
ANY SORT OF DAMAGE DONE.
Hope this helps you guys

This can also be done via CWM usinge the delete battery stats option.

Sure But as stated this is for new users Who are not well acquainted with recovery

Just following logic. If someone has started flashing Roms and rooting devices, I would be surprised if they had not discovered CWM

after doing research on all methods to recallibrate checking pros and cons finally i got the answer brothers...its very simple no need for cwm or drain full abttery kill your batery download recallibrate delete batterystat.bin....all fake bother....just do a simple step remove your battery for 2-5 minutes and than on it....you are recalibrated....simple

but what about batterystats.bin? Why is it there? ^^
And from which research resource you are talking?

Hey..it works,thanks for your efort in researching this
I'm quite desperate coz ever since I'm installing creed 1.7 seems like my bettery drain very fast,too bad coz I like this ROM. Last night I charged it to 100%,then I go to sleep(so my HH is idle) but when I woke up 3 hours later,my battery stat already drop to 84%,strange. So I try plugged out my battery for 5 mins and voila..now it's written 53% but it's been like that for half hour so maybe it's quite stable now. Thanks again dude

since 13 months i m using fit bro and the most annoying thing of android was battery backup so researched almost all sites of android and lion baterry ....checked alll methods of battery boosting from apps and ram clearance,...the battery stats.bin bro yup that you dont have to take care its android system which adjust itself and recalibrate when you make your android without power means no battery for a while and when you insert it again the system itself recognizes....killing your battery specialy lion reduces its self life also its the number of cycles so whenever you charge charge your phone to fullest not like every 5 min you are charging your phone once a day to the fullest just check what i said bro its really works just believe and c

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.

I did battery re calibration once and it made no difference at all, having a google engineer dis-miss all the myths is good enough for me buddy.

I installed Battery Calibration 1.2. When open it writes the following:
1. Plug in your phone to the charger
2. Wait till it charges to 100%
3. Click 'Battery Calibration'
4. Unplug your phone

Galaxy S6 Not displaying correct battery.

I have had this issue for a while and have been switching roms in search for a solution. My phone is draining battery no matter what rom I am using, but when I instert the charger, the battery instantly jumps up about 15-40% depending on how low it is. Does anybody know what causes this and how to fix it.
SM-G920i
Both Xtrestolite Deodex 6.0.1 and Xtralite Deodex 6.0.1
Pretty sure both roms use Arter 97 kernel.
Any help would be appreciated

Did you try to recalibrate it? Also, you should use Greenify to help you reduce battery drain while phone is not being used.

Here is a good guide which shows you how to do it. It's helped me, so hopefully it will help you as well!

Re-calibrate your battery,there are a few on the play store i used it each time i install a new rom (not needed for updates really). They do require root though. Also samsung introduce a feature which when your battery drain there willing be atleast 10% of battery remaining even though the phone shut down. This is an emergency feature and allows you to send or make a call with the last 10%

Battery drain

Hello,
I don't know what can I do. I must charge the battery 2 times a day. With custom ROM and Kernel ,also in stock unrooted and with locked bootloader. It's not normal, I think. Has anyone the same Problem? Maybe the battery is damaged. What do you think?

I think it's damaged .The second charge today.

Mine is very similar. I think our batteries are gone. I am about to do a factory reset and reinstall my ROM to see if it makes any difference to battery load.

Did you try to go back to Lollipop 5.1.1 firmware .264? Works miracles for me... as I have >6h SoT (screen-on-time) on Lollipop, but <4h SoT on Marshmallow
/PS: In my use case anyway, yours might vary, yet I believe you'll see a longer lasting battery

Same problem for me until yesterday. After repair with Sony Bridge for Mac and installing only important apps it is ok.
I can not add screenshots. BetterBatteryStats says 2,8%/h. 73% Deep Sleep. Usage: 1d 5h 12 min. Now 15 % Battery remaining.

I start from beginning and the what happens.

First try to see what apps run in the background, maybe there are some services draining your battery. Is Mobile Radio Active draining the battery? If not than 100% that your battery needs to be replaced.

Try Nova Battery Tester (look for apk) set to long test and see what capacity it measures.

thinking to switch from MM to LL also...there is noticable battery in favor LL.except that no difference between this to.... what version of LL rom do you use?

it seems after reset and deploat alot of Stuff from MM ROM the Battery lifetime is better.
Also tried the new Android 7.1.1 AOSP ROM, perfect the Lifetime. But the Camera is really bad.

Battery Life Improvement

Anyone noticed a slight improvement in the battery life of their V-10 after the stock Nougat update?

Yes but not a whole lot of improvement I still run out of battery near half my day. I need a 6,000 mAh battery

I've noticed a difference. Usually within an 8hr shift my phone would normally be between 20-30% but last night I still had 70% after the usual 8hrs.. I think it's a big improvement for my phone and battery.

Are you using the stock, unrooted ROM?

I am using stock rom but the screen uses about 60-80% of battery life I am a very heavy user watching YouTube for hours and gaming so to be expected of any phone batteries life
---------- Post added at 07:03 PM ---------- Previous post was at 07:01 PM ----------
I have not tried any other batteries other than the stock ones I use a otter box case so. Most none oem batteries won't fit

Yep gaming and high screen usage will definitely kill the OEM V10 battery....

So I'm on the update I have ran it oem stock, rooted with magisk, and with root and test build of xposed, oem stock has a nice battery improvement, but with root/magisk moduals, and xposed I think MM 6.0 Had better battery life. I think this will change after the official release of Xposed for N 7.0

I never rooted my V10, is the battery life on those ROMS you mentioned better than the stock ROM?

I've noticed great improvement since I have the perfect environment for Nougat's doze. Flat on a surface, screen off for a period of time. I went from 5-15 end of day to 70ish. Those who have the phone in their pocket, or are more active may want to pair with greenify's option to make doze more aggressive to see better battery life.

Root has a small drain but, N 7.0 is awesome and even with magisk root installed its better than stock MM 6.0. If you ever went to using xposed then MM 6.0 with Xposed still wins in terms of running a modified system. MM only wins because its able to run a official build of xposed... I can't tell someone to get root If they don't know it well, but the new N 7.0 is a good update that adds batterylife

I've rooted several phones and tablets in the past, I haven't bothered to root my V10, been happy using the stock ROM

By rooting your phone, you get the ability to change stuff deeper into the phones software, which means that you can install apps that will do the trick for you. Some of them require Root access and some require even deeper changes to your device software by using xposed framework. By using such software you can stretch your battery life by too much. I remember i managed to get my One Plus One to drain just 0.3% (thats 13 days battery life without using the screen ofc) per hour, but it cost me some slow sync of apps like gmail, facebook, messenger, whats up etc. Thats because i forced these apps to check for updates once every 5-6 hours or so. So you don't have to use a custom ROM in order to get root or xposed framework.

So I use my phone like all day screen on time is like 9h.... I'm running the 10000mah huge battery that has the large. .7inch thick case it's on amazon. But any way my system hasn't been great on battery life since I use tones of apps and mods ect ect.... I am only posting this to say a few things. I don't like the unofficial xposed framework all that much on N 7.0 I love the update though my battery life is unstable at best. If you are going full out mod crazy like I am use battery saver ware it turns on immediately and run it all day. Some days I go all-day at work and still have 70% battery left by 6pm other days I run it down to 50% by 6pm... Without battery saver on though it's not good battery life. Right now I'm on Nougat with magisk 13.3 viper audio xposed v24 and tones of mods... With all the add-on stuff I am thinking something is using very low optimization.... MM was a little more stable and predictable if you are happy with stock roms then the nougat update plus running battery saver on full time should give really good results

Battery life
Yes man, in short the battery life of this device is completely, as you mentioned, "unstable".

Custom ROM battery drain

Hello!
Does any of you have an idea why do I have a huge battery drain on custom roms?
I have tried nearly all of them (all based on OpenKirin), and no matter what I do I cannot get more then 1,5 - 2 hours of SOT, and I have to charge my phone daily. With EMUI I only charged my phone in every 2 days, with 3-4 hours of SOT.
Here's what I've tried:
- Installed L Speed, set it to Battery profile
- Installed HEBF instead of L Speed, set it to medium battery saving
- Installed Kernel Adiutor, set the CPU governor to Blue_active or Darkness, set I/O scheduler to zen or bfq (with whitePug kernel)
- Installed Greenify, set all apps that I don't want to keep running to it
- Installed Titanium Backup, I froze some system apps I don't need
- I checked WakeLock Detector, but I didn't find anything bad, my phone was 3% awake, the rest in deep sleep
- I installed BetterBattery Stats, no result
Still in 7 hours overnight from 100% my battery drained to 93%. In 9 hours with minimal usage and approx. 10 minutes SOT I'm at 82%.
I couldn't find solution to this, this is the case in ALL roms...
Can anybody help?

Thats is realy bad and big battery drain. If you goes now back to emui, battery life is the same like last time on emui? I mean if isn't something corrupted in phone after flashing custom roms
edit: I think you try to do factory reset
edit1: You always use only one optimizer? Becasue if u use this can make some errors between two optimizers if work two together
edit2: You try just flash custom rom without any change in setting and any optimizer and, battery drain is still huge?

I have used LSpeed + Kernel Adiutor OR HEBF + Kernel Adiutor OR Lspeed only OR HEBF only. I didn't mix them. I tried with and without Greenify as well. I've already went back EMUI once for the same reason, battery life is great there, no issues.

Have you tried going back to the EMUI and check if everything is fine? It could even be your battery that is damaged because of over heat or using 3rd party charger.

Rommco05 said:
So good message is phone isn't broken. You always download latest version of custom rom? Try just once clean installation, wait what is your model of phone FRD...?

Wifi always nearly full (with EMUI it's always full), network signal nearly always full.
I've tried clean install many time. Currently I'm on OwnROM. I've flashed the WhitePug kernel in the morning after the 7% drain with stock kernel.

On custom roms the phone isn't overheating, and I use stock charger.

Thanks! I've just flashed OwnROM again with Dalvik, Cache, Data and System wipe. I flashed gapps and I installed nothing else. I charge my phone to 100% and I let it be on the desk till the afternoon. We'll see. If it's good, maybe some installed app causes the issue.
Any of you use Viber? I have Messenger, Telegram and Viber all installed and runnin. They don't show up in the battery consumers though... On EMUI I have no issues with them.

Sure thing! Another question, is that normal that on Custom roms it takes much LESS time to charge the phone to 100%? It takes longer on EMUI, especially after 80% and up.

Well, nothing changed really...
2 hours on battery with 3 min screen on time 2% drop. That's 1% / hour, just as last night.
