Help Cell standby at 34%, TWS is at 2% only, WTF

Tried hard reset. Thanks for suggestions, their working. One question though, my Android system is at 42% battery usage. Is that normal?

It depends... What is your time since unplugged? You say you charged your phone at night and it was on standby all night... Do you mean you unplugged it fully charged and then went to bed and when you woke up it was at 70%? What is your Up time and Awake Time?

To be honest with you, the only way to figure out what is causing the issue is to start from scratch and add one item at a time. Hard reset and run default for half a day, if all is well add an app or make a change. Then run that for a good 3-4 hours before your next change and so on. I guarantee you'll see exactly what is causing your issue with this method.

Any ad supported apps or widgets on your phone? They can kill your battery constantly grabbing data.

You can stop auto updates with those, thats what i do and my battery goes through the day pretty good only strange thing was when i left work it was around 6hrs and some min since last charged, and around 11:30 i did a shut down and put it back on and i took about a 3hr nap and for some reason it says 5hrs since unplugged, maybe the shut down caused a reset.

No, the more accurate way is to install SystemPanel Lite, enable historic monitoring, and watch what stays active when your phone is off. THAT will tell you what process is sucking down CPU and battery.

I had a really weird problem when using a custom ringtone.

I created a "ringtones" dir on the SD card and set my default ringer to an .mp3 file in that dir.

The very next day, even after charging all night, my battery was draining extremely fast.

Long story short, I deleted the ringtones folder, went back to using a default ringer that came with the device and everything was back to normal.

My theory is that since I was using a ringtone on the SD card, the phone kept the SD card powered which didn't allow it to sleep.

This seemed to be evidenced by the fact that after assigning the custom ringtone, Android System was #2 in my battery list. (cell standby was #1)

Before assigning the custom ringtone, and after removing the custom ringtone, Phone Idle once again became #2 in battery usage.
