When I was using 2.3 on other device battery calibration was a big issue. If I've recently updated to a new version of stock do I need to do battery calibration? I don't find this option on TWRP recovery.
Battery calibration is now deprecated and considered useless.
Yes, after some digging I've got that you don't need this anymore.

I was wondering if Xperia L has battery calibration issues like some other Xperias which are solved by restarting to show exact battery left.Out of box, it was charging 100 percent and then i flashed my ftf (Uk which i made myself).After that I calibrated and it was showing till hundred again.Now after updating to 4.2, its again not charging till 100. I know battery calibration will solve the problem but why is it bothering me?
Anyone having this issue ?
On my other devices I didn't need to calibrate at all.
Have I got a defected battery?

I believe this is one of the issues from the 4.2.2 update.
If you want to revert back use FTF via Flashtool
You can also install a custom rom like Xperia Clean 'n' Tweaked

Cheers for the answer but I am noticing this behaviour since day one I bought Xperia L. And I rooted it the next day I bought it with unlocked bootloader. So I couldnot really check it out of box really. I remember I charged it till hundred first time so there wasnot any problem. Now It was on charge for three hours and it still showed 96 and volts were about 4300 which meant it was fully charged (kind of overcharged).
I understand your point about 4.2.2 and going back to another ROM but I am developing a ROM for Xperia L myself.
4.2.2 didnot show me any bugs really and I am quite thinking about using 4.2.2.
Plus I am waiting for device tree for making a ROM from source!
And my question only was, are you experiencing it?
hi, i am facing problem since i flash to cm12. android system is drain battery most.. is there any way to fix it? my opo is rooted
Same here too
Hi,
I recently obtained a N5, however after reflashing the device with the latest 6.0.1 factory image and installing *any* modified kernel (including Chainfire's only-SELinux-modified kernel), battery percentages while inside Android (recovery seems to read them fine) are reported as 3000-4000% (currently after a night of charging, it's at 4,320%) - of course such values aren't really helpful when using the device as a phone!
I tried looking such issues up on Google ('battery over 1000%' and similar terms), but couldn't find anything related.
Could anyone be of any assistance?
I have the same problem, have you solved it?
It looks like it`s reporting voltage instead of percents. Weird.
The problem seems to be related to the kernel or boot image.

Hello, i reality want to activate the LG function Knock on on my new motorola moto g 3.
How I can enable it? I'm on 5.1.1 stock lollipop because I've read that it works better than android 6, I read too that this function need an custom kernel, I prefer to keep my stock rom, is really working amazing, are a way to use this option without touch the kernel?
I want the real knock on, that works with the screen off like LG phones, I've tried some apps but they keep the screen on or the proximity sensor on and this drains the battery obviously, so that's not what I'm looking for, my device is rooted.
Thanks.

You heard right, this requires a custom kernel that has DT2W (Double Tap to Wake) compiled into the kernel, then you have to use a tool like Kernel Aduitor to enable it on each boot since even kernels that have this feature usually have it disabled by default.
Not that this will increase drain battery anywhere from 1% to 3% per hour (usually on the lower end of that range though, depends on usage)

Thanks for the full answer! Well looks very well 1 or 3% of battery for that option, you can say to me what kernel is recommended for this?
AGNi or Explosion kernel are the only two I know with DT2W still enabled... FireKernel used to have it, but it was removed a few versions ago.
Make sure to backup in TWRP before flashing a kernel, if you want to switch kernels after flashing a custom one to try something different, restore the boot partition, and boot fully before flashing a different custom kernel.

Really thank you for your help, now I have another question, do you know how to activate the option on camerafv5 for manual focus? It is possible? I've read that will work with the new camera2api included on lollipop but I dunno how's that.

Pretty sure the G3 doesn't support Camera API2

Hello! Let me know if this is the wrong place but ever since I got my 3a a few weeks ago, I've been disappointed with the battery life. The stats are below. The "Averaged per complete charge" are completely inaccurate as I've never hit > 4 SOT, ever. I don't really know what to do at this point because I've tried cleaning out everything I could.
These stats are on a regular work day, light usage. Texting, 2 or 3 calls, etc.

Any tips?
If you're on stock, then custom kernel should help. I'm quite happy with the battery benefits that EX kernel brought to my Pixel 3a. You can find it here - https://forum.xda-developers.com/pixel-3a/development/kernel-pixel-3a-xl-elementalx-1-01-t3931185

Thanks. A poster elsewhere recommended a system reset and flash the newest update and release basic apps for a few days to see how the battery does.
Can I flash a custom kernel without root?

In Android 9 you can use TWRP custom recovery to flash kernel ZIP without having root. If you're on 10 you still might be able to flash it without root in fastboot (or should I say in "fastbootd"), but I didn't try that.
