Cell standby high percentage

[asis217]

Hi,
Just had my new m9, with 6.0.
I noticed my cell standby in my battery usage list is over 30% most of the time.
What can you say about it? Is it normal?

Welcome back! No that's not normal. High Cell Standby battery usage usually means you've been having poor cell signal, which increases battery usage as the phone struggles to maintain the signal. What's your cell signal like?

Happy New Year!

Hi, and happy new year.
My signal is really weak sometime but quite normal i guess. The weird thing is that Gsam shows normal phone radio usage (see attached) not equivalent to the "cell standby" in the "settings" that shows 23% Wright now.

Are those GSam stats from the same usage period as when you say the Cell Standby really high? It woud be helpful to see them side-by-side for the same usage period.

Yes, they were same time (23% on the stock settings)

It'd be useful to see more battery stats. Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).
