It is for motorola, will it gonna work on htc ? Also when I charge my battery for 4 hours or for 48 ( turned off the phone I mean) it still lightning red led not green. Always it charged till 71 %

Worked for me on my WF using CM 7!

Okay I will try this, nut what about app Battery Calibration, does it work ?

Don't use an app because it is software based, but the guide i've posted is hardware based!

Ok thanks for the information !

1. While in Android, charge up to 100% and leave the phone plugged in.
it dosen't charge up to 100% to use this method

In this case 100% are the maximum you can reach. You can check the exact battery status in system settings!

1. Sorry, haven't thought about that. Yes, it has to be rooted.
2. If your phone is rooted you can find it with root explorer.
3. Yes, for rooting your phone needs to be S-OFF
Maybe you can use that one - found it in another topic:
1. Power on your phone then connect to your Charger and Fully charge until the LED changes Green.
2. Disconnect your phone from the charger and then power off.
3. Reconnect your phone to your charger with the power off and wait for the green LED.
4. Disconnect the phone from the charger and power it on.
5. Once the phone has fully booted / ready to use ... power off again.
6. With the power off connect the phone to the charger and wait for the green LED.
7. Disconnect from the Charger then power on and use normally.
Needs no root, but I haven't tried that yet. Most of the users said that it worked, but keep in mind that battery calibration can always damage your battery.

My battery never charge up to 100% last time i saw green light from fulfully charged phone was last year. I can charge it for 48 hours turned of it still wont be green

Which status is shown in phone->status->battery status?

[Q]Battery acting weird

My phone was all fine, till i flashed Arco's CM10, then my phone started randomly switching off. When started, it showed 0% battery, which was weird as it was always properly charged.
Then i restored my CM9 backup, to check if it was a ROM bug, but I got the same error again.
Attached screenshot for battery stats. Battery problem or Software bug ? Anyone with same bug ?

After flashing the ROM, did you wipe battery stats? If not, that will probably be the cause of the weird readings......
Basically, over time, your phone would have calibrated the battery usage to your previous ROM....when you installed your new ROM (that has different battery usage patterns) your phone is still trying to apply the stats from the old ROM which is what is causing the problems.....wipe your battery stats then complete 3 or 4 full charge - full discharge cycles, and things *should* settle down....

Tried that...
But it gets weirder and weirder :/

Try the battery calibrator on the playstore.
If it still persist then the problem is in your battery.. suggest you change the battery with the new one
Pressing "Thanks" button will be much appreciated if user's posts useful for you

Or you can try this:
Clear battery stats via CWM. Turn off your phone, and charge it. Wait until the charge indicator shows up on screen. Then turn on your phone and leave it until it's full.
Sometimes when I get batt weird reading, that trick works for me.
In some occasion I found that offline charging and online charging shows different battery level.

when should i plug the cable if use ur trick?

Clear the battery stats first via cwm then turn off your phone after that you can plug in your charger.

Just like reddvilzz said above. After charge indicator shows up on screen, turn on your phone (but do not unplug the charge) and leave it until it's full.

I think you should buy a new battery because your battery drains too much. I bought a new battery on amazon and I spent only 20 euros.

Hello,
I have problems with baterry too since i flash my phone with Slimbean rom 4.1.2. Since i have this rom my battery goes from 100% to 0 in 6 hours, before i had original rom i had battery for 3 days. So this can't be problem in battery. Anyone know what to do ?

i ,, too,, am flashing so many roms,, trying each and every one out there,,,

after i connected my phone to a wifi,, and then,, i switch it off,,,, i noticed that it will then start to reconnect by itself,,.. dont know when ,, or even how,, but its reconnecting itself,,, it continues to scan,,, ... result is that,, when i touch my phone... its really hot,,, and because of that,, im sure my phone isnt going to a deep sleep state.. (correct me if im wrong)
that is when i search the net and found a way to disable a wifi reconnection thru terminal emulator,,,,
and that is by entering this one
su (enter)
svc wifi disable (enter)

i usually do that after i use my wifi,,, to ensure that it wont reconnect again,,,
and im just wondering why in CM,, its always reconnecting,, while on gb roms,,, it doesnt....

after you calibrated your battery let it drain to 0% and full charge it and use it as usual you will feel that your battery stand more and more
and by time it will be ok again

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.

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.

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"

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.

but i have had a screen on time of about max 2 hours and my battery was down after 8~9hours... -10%battery per hour in power saver mode with lowest brightness
heere my results :
6:25 100%
74% after 2h30m with screen on 21 min
45% after 6 hours with 52min screen on
12% after 9 hours with 1h16 screen on
3% after 10h15min with 1h18m screen on
after the 10 hours i have had battery usage:
40% Mobile Network Standby
29% Apps
15% System
6% Phone inactive
it was defintly better than before but i have had also the battery draining... btw im on lees r143 with cleanslate kernel....
i install elementalX Kernel with a bit of uc and deactivate some stuff i dont need i will test it tomorrow and report....
maybe we find a solution together....

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

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.

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?
(Im on LeeDroid R147 Oreo and battery tip is done. )

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.
