[Q] Samsung Galaxy Note ii N7100 Bad Battery Backup !!

Hi,
I bought Used Samsung Galaxy Note ii N7100 4 days ago ,which was around 11 months used in good condition .
When I bought phone first I flashed it to Prerooted JB 4.3 found on xda-developers threads only .for 1st full charge i got good battery backup .
After that day i am not able to get half of that backup , I didnt do anything extra , ive uninstalled evry new apps , then I did factory format . still nothing
I am using power saver mode , but nothing . getting very bad backup .on first day i got gud backup n after that i started to gave me worst , why is that ? I am charging my phone from travel adapter which came with phone . it takes around 3 -4 hrs to full charge , any help ?

Using stock charger will indeed takes 3-4 hours to fully charged the battery.
Download Battery Doctor from the store. When your battery is below 20% charge it until Battery Doctor says it's complete. Tap 'Optimize Now' button to let it kill the apps which running in the background.
Go to WiFi advance setting, disable location service that Google can use even your WiFi is off (new setting in 4.3).
Set your mobile network to either 2G or 3G only, don't use automatic. It seems your mobile network keep doing something, maybe the signal in your area is not good.

In standby overnight, maybe 3-5% battery drain. A lot of things come in play though such as what apps you have installed, if your on LTE, or 3g, or wifi, or even go into airplane mode at night, etc.

first of all , I'd like to thank you for your reply ..
I've bought a new desire 816 two days ago and I can notice something wrong with the battery as it drains faster than normal
and it gives false percent as it increases after restarting the phone ..
I've tried to calibrate the battery by letting in turn off by itself then recharging it to 100% but then I realized It's still giving me false number
I don't know what to do ... It would be great if you can help

Have you tried a battery calibration app such as the one by NeMa in the PlayStore? It requires root but it basically asks you to charge your device to 100% which is done from empty to max in about 3 hours. At this point you go in the app while its still plugged in and "clear" the batterystats. This is the file that tells the device how much charge it can hold and on some devices this file gets buggy/glitched. It will wipe this file away and generate a new one based on the charge the battery holds at max. It then asks you to use the device as normal until it dies and recharge to full afterwards. This has worked for many and I hope it will work for you as well.
If you have excessive battery drain look at the Power settings and review the usage. If it shows a green line on awake and it doesn't show the same matching the screen on time then you have a background app sucking battery from the device. Facebook and its Messenger are known to be the culprits but if you download Greenify from the PlayStore. It will allow you to hibernate practically every app so there is no battery drain when your device screen is off. In combination with this app I am able to get an average day and a half of use with no charge and normal use with Videos, Music, Facebook, Messenger; etc. I average I use about 6-10 hours on this device with pure stock w/ root & Greenify with battery calibration via app done.

Yes, Greenify does require root in order to work but it does work flawlessly.

Unfortunately, the lack of rapid reaction because I was too busy
Pressing the power switch for exactly two minutes and the device will tell you Alglaq Do you want to or not agreed to the demand and calibration Congratulations to you
Thank you

I fixed my battery issue. the exposed software killed mine relating to the same issue i believe you had or have. reporting wrong percentage. once had 50 percent, took it back out of my pocket and within 5 mons i had 4%. wouldnt charge.
Power it off... hold all 3 buttons (power+volume up+volumedown) after 15 seconds it will boot back up. this calibrated my battery. hope this works for you.

Wrong battery percentage report is fixed by HTC on 1.58 rom update. it works fine on 1.58 Rom

My battery on my htc is draining fast I think it went from 100% to 83% percent in like 20 minutes is this normal? I have disabled everything that I'm able to disable on this phone but once it gets to 70% the drainage kinda slows down

[FIX] Battery Drain,No Deep sleep, Android os wake-up all time

Tested on Lineage OS14.1, PurefusionNougat, CRDroid (not tried in other ROMs, it may work)
After trying a lot of modifications in two weeks regarding battery drain due to android os wakeup all time and little or no deepsleep, found a simple way to solve the issue.
1. Calibrate your battery according to post #9 (https://forum.xda-developers.com/showthread.php?t=2765663)( (Essential- it will fix almost all errors regarding battery)
2. A simple build.prop tweak wifi.supplicant_scan_interval=200
Add this line to system/buildprop using a root explorer with root permission " wifi.supplicant_scan_interval=200 " and reboot.

Screenshots after applying the mode

I edited the build.prop file via BuildProp Editor in the app store. So does i add that line in the beginning of the file or at the end?

do build.prop edits need a reboot to work ?
But yeah... WiFi has always been an issue on the HTC10 -.-

Battery Caliberation that also worked for me according to this xda post by @bikercr https://forum.xda-developers.com/showthread.php?t=2765663
Thanks to @bikercr
His Post
"This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons when phone is ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
NOTE: Another potential fix for battery/charging abnormalities if this procedure fails (esp. after an OTA update when corrupted files can remain stuck in device cache partition)--clear cache partition using this method: http://forums.androidcentral.com/ver...ted-phone.html"
New screenshot attached- Still 100% after 59 minutes (Note: without Gapps) Running crdroid from @andybones

Good morning, the fix works with Leedroid Oreo?? or is it for Nougat AOSP ROM?!
Thanks...

So how is your SOT after this fix?

This fix increase standby time (battery drain and no or little deepsleep due to android os awake all time)
This fix have little impact on SOT. SOT depends on many factors like Screen brightness, Surfing on 3g, 4g or wifi, playing Games, watching videos etc.
A Little Story
I bought this device through OLX and the seller selling it due to poor battery backup and warmer device even in standby. Due to interest in tweaking and modding from my first android device(Samsung spica 256mb RAM!) i bought it (with Android MM). Found the device doesn't enter in to deepsleep and android os is in the top of battery consuming. Two weeks of flashing differnet roms, Kernels, tweaking kernel through Kernel adiutor app, disabling and removing of apps , build prop edits etc. One day i noticed that my device goes to deepsleep almost suddenly after locking. Flashed the device again and do the tweaks one by one to know which tweak give me the result, and found the wifi scanning interval build prop tweak is the reason.
And it runs smoothly almost all time and some time it shows battery drain. So done some more googling and found this post in HTC One (M8) forum https://forum.xda-developers.com/showthread.php?t=2765663)(. It realy helps to completely overcome the Battery drainage issue. Then i tried almost all nougat roms and all of them are giving excellent battery backup.
Now my device have no deepsleep battery drain issue and now trying some bloat removed nougat stock.

40% Mobile network standby is due to low network coverage and network use more battery to establish a good connection.

on my phone , wifi running is always 100% , I think that is "always scanning option enabled", so this option is draining my battery?
or
which I sacrifice doing your method to my phone?

wifi.supplicant_scan_interval=200 if you switch on the wifi always scan mode, then wifi trying to search for available networks all time, if you add these lines to buildprop it pause 200 seconds between scans and it help to reduce battery consumption, drawback - time for find a new wifi hotspot may increase.
