Battery reading issue on Skyrocket

Very weird, and this happens all the time, everyday. About once to three times per full charge since i have the phone. I restart the phone for some reason and when i get back, i instantly lose about 5 to 25% of battery.
I'm rooted on stock rom...also i'm guessing this is a calibration issue so i am fully uncharging / fully charging battery tonight to recalibrate it but in the mean time i wanted you guys to confirm if i'm right
Also if this is in fact a calibration issue, does this mean that my phone is discharging faster than it's actually telling me?
Here is a screenie
one big peak loss a few hours ago and a smaller one just now

Battery life on N5

So I have been using my N5 with average usage. I do not do crazy gaming nor do I have all types of battery saving apps. But I have noticed that the battery life is phenomenal... I don't know if the phone is misreading the battery but last night I left my phone without charging and most of yesterday without charging. I also have a cm alpha installed and lowered CPU frequency when screen is off (to 300). Here is a screenshot of the battery meter

Could this be a misread? Is there a way for me to wipe my battery stats and test then?
Thanks,

JLW Note 4A External Battery Cover?

I managed to fix drains on my N910F and now it's working smoothly, the only thing bugging me now is battery life, always around 4-5H SoT depending on my usage pattern so i ran into this thing today, anybody knows something about this thing?
It says JLW Note 4A-1 on the cover i was looking at, apparently there are two versions, one with 3800 mAh and this one with 5500 mAh named 4A-2. I know it can't be true 3800/5500 mAh but if i can get 1 or 2 hours extra out of it i would buy it, the only thing that is stoping me from buying it is zero info about it.

Android 12 has an option to stop charging at something around 85%... (to protect the battery life)... did you perhaps set that option?

Redmi note battery Drains to fast

Asking if how to fix redmi note 9s Drains battery so fast? I already tried the calibration and formatting it but the problem still occurs. Symptoms of it the phone always rebooting when I open wifi,camera and share it. When it happen the phone drains battery bit by bit and upper back of the phone heats. With 3 hours of screen time only 30% remained. Appreciate fast replies thanks.

The more apps are running ( whether in forground or in background ) the more the battery gets drained.
