cell standby or phone idle?

I did a battery wipe in cwm and my battery life went up a lot. for two days I got like 22hours on normal use, 4g, Wi-Fi, you tube, music, etc. this morning my battery status was at 80% showing cell standby and phone idle. should it be either standby or idle for overnight? if there are no app running? there was nothing else running, is it normal for both standby and idle to show for the overnight?
thank you

Cell standby is battery used by the radio.
Phone idle is battery used when phone is idle.
Pretty much even if you're not using your phone it will still give out signals back and forth (thats how you get text/calls) unless you turn it off completely. Phone idle would be how much battery it uses while its on idle but it also goes based on the time. So if say you get about 1% battery/hr idle, and you never used your phone for 4 days but now you're out of battery, your stats would be 100% Phone idle because the idle is what used the battery. If you play a game that uses 2%/hr it will factor in with the percentage with everything else of how much power its using. Example say i lost 5% battery within an hour and 2% of that is from idling and 3% was from a game etc...
So when you're sleeping and the phone at anytime access a connection (text/fb notification/updates/sync) it will be on your cell standby.

About S7 battery life

Hello guys, I have a few questions about the phone's battery life. i've noticed lately that my phone drain its battery pretty fast, it drains 1% every 3-4 minutes while browsing or messaging, also it drains 13% overnight (9 hours wifi on) on standby, so my questions are : is this draining normal? if not then what should be the phone's average battery drain? keep in mind that the phone is 3 months old so i think its odd that is draining more than 10% overnight with no apps running in the background, from what 've heard the phone shouldnt drain more than 5% on standby.
thanks!

Mi 11 lite (miui 12.5.1) battery drain while idle

Hi all,
My phone drained 14 percent battery yesterday while idle for 9 hours. The interesting thing is when i add the mAh usages that i see in battery and performance tab it only adds up to 6 percent battery usage. ( i calculated and confirmed with time that 40 mah is aproximately 1% battery)
Also this morning i am seeing an unusual drain as well while the screen is on, it drained 5% but it should have draned only 3% because it says it drained 138 mAh.
Does anyone have any idea about this problem?
This also happened 2 weeks ago and the only thing common both days were, i charged my phone slower (charged using usb on the car) instead of using fast charging.
I also leave the screen shots that shows the battery usage.
Put the phone into Airplane mode when idle: this may save some battery.

yes of course but the battery drain I explained sometimes happens I actually think its a battery indicator bug. Because it shouldn't be draining this much battery because it doesn't show any unusual drain on battery information screen contradicting the percentage lost (14% battery was drained but according to battery information screen it should be 6%)

Question Phone is off, but battery is still draining

Is anyone experiencing a battery drain even though your S22 Ultra is switched off? I'm experiencing 4% drain every hour. 32% when every night when I sleep with my phone turned off.
I turn on power saving and extra dim using the bixby routine for the period that I'm in bed sleeping. It loses 1-2% ph
If you don't mind, can you try turning off your phone for the night and see how much battery percentage it loses? Mine went from 32% to flat 0% by morning. I had not realised this until recently. I tested in the morning by turning off my phone for an hour, it went from 60 to 54%. That's like 6% in an hour. But if I keep it on standby , it'll be 1% down in an hour. It's the turning off that is causing problems.
I know some laptops will drain battery power after shut down, but phone?
Exy or Snap?
Try checking in details with a battery monitoring app (e.g. GSam) to see what is/ are the culprit(s).
Also take a look at here for some useful tips.
It's strange that a lot of battery drain when phone is completly off.
In my opinion it's short circuit or battery is fault.
If phone is normal on are you see too battery drain?
When phone is switched off battery shouldn' experience any drain, or at least any noticeable drain in a short period.
Remember, when you bought your phone it came with battery half charged, and that was probably months after it was assembled and sealed in its package..
You should take your phone to a service or replace it, if possible
maybe somewhere on the PCB there is a short circuit. I ran into the same problem when using Xiaomi Mix 3 11 months ago.
