Battery Indicator not displaying correct percentage - Droid X General

Hello all,
I have a rooted Droid X and I am having trouble with the battery indicator. For example, at just below 4200mV it will display 100% battery which seems correct. However, after the battery reaches around 70%, the indicator drops to 50% in one swoop. Right now it is showing 46% at 3699mV. This problem started on MIUI and I reflashed the rom. That did not fix it so I SBF'ed back to stock which did not seem to help either. I just flashed VXL and I am still having the same issues. I have also tried the various methods to calibrate the battery and it seems like the battery is charging to its full capacity, just that the indicator is incorrect which causes it to shutdown well before it is out of battery. Any ideas?
Also, I'm not sure if this makes a difference but whenever I reboot I seem to lose some of the settings that I saved before the reboot.
Thanks

Rule out the possibility of a bad battery. Check the battery connections are clean, and if you have access to a different battery try it and see if the phones behaves differently.
If you swapped batteries and battery still drained in <6 hours then it is best to back up your files and do a full factory reset.

Battery draining after reboot

Hi guys, my battery need to be replaced or is a software bug? Because my phone is charging very fast but when I reboot it with 100% of battery level, it goes down to 92%. Same happens when I open apps (like Facebook and Hay Day). Both situations happen with and without the charger. I have already flashed the rom and calibrated the battery many times, no changes. Booting on recovery (TWRP) it show 100% and when I reboot again in recovery it goes down to 92%. I don't know what is happening. Also, measuring with Ampere, this happens: ​

try full wipe, if thats not working try undervolt maybe? Never saw that, you can try disabling keep awake of other apps in App Ops. Hope something will help atleast.
Changed the battery and the charger connector (the old one was oxidated), still the same :/ I think I'll make a backup and reinstall the ROM (Pure Nexus 6.0)

Phone not sleeping/entering doze. Crazy standby drain.

Hi all, my exynos variant of s7e is experiencing crazily high standby drain. I don't remember seeing this kind of drain during the first few weeks of getting the phone.

I did a test to show, phone unplugged at 100%, left on table without using. ~12hrs later. whopping 60% gone. It's only the 3 processes you see, nothing more.
Anyone have the same problem? Any idea how to find the cause? Used to have great battery life. It's not normal right?
Have a look at these threads (which have been right under your nose in Q & A )
How many of you experiencing high android system battery drain?

Post your battery life!!!
Mine was doing that also, so I did a factory reset and I didn't use smart switch to add my apps and stuff. Its been sleeping beauty since. I know its a pain to reset, but was worth it.

LOS A2017U Battery stats

I'm trying to understand some battery stats. Lately in the past month I've noticed that my battery life has not been good. Certain Google apps like YouTube, Photos, and at times Play Music will cause high battery drain with minimal use. I've tried clean flashes of LOS and I'm on the default LOS kernel. My screen brightness is set to auto and 50%. Each charge cycle I get less than 4 hours of screen on time. I keep WiFi and Bluetooth on at all times but I still feel my battery life should be better.
Anyone have some suggestions or ideas or am I getting the best out of this phone for the way I use it?
See screenshots of battery stats.
As you can see at about 50% battery used, the Photos app used 7% battery without being on for about 3 minutes....that doesn't sound right to me...

Phone charging all weird

I can't tray explain it but whenever my phone is really low on battery (let's say 10 percent) it doesn't seem to discharge it just stays at 10% forever, that's at least what Android thinks (pic included)
And then after plugging it in it charges really really fast, probably a percent of charge every second or so until it reaches about 20%
Could it be that my battery is dying? Software issue maybe? Having really bad battery screen on times as well.

Hello,
Try recalibrating the battery.
For example, with the following app: https://play.google.com/store/apps/details?id=com.vitula.batterycalibration
