"Cell standby" is draining the battery (51%)

[anon(730457)]

My mom told me she has to charge her tablet battery twice a day, so I went into Battery stats and Cell Standby was 41% while Android system was 29%, WiFi was 15%, and Idle was 14%. She uses it at home connected to WiFi and only brought it out once or twice on the road since buying it a month ago.

This is really insane for battery usage while she's connected to WiFi; it's not a phone, she doesn't use it for text messages (though Verizon assigns a number to it so it's possible), and there's no reason she should have to charge the tablet twice a day just for this.

I couldn't find any way to disable it (disabling Mobile Data doesn't turn off the bars at the top, which is the same in the icon on the battery usage list), so I had to show her how to turn on Airplane Mode then turn on WiFi... all of which is a little too much for a granny just trying to read on her tablet. I haven't noticed this problem on iOS devices, so is there a better solution (does disabling Mobile Data actually prevent Cell Standby drainage?), or does she need to jump through these hoops every time or get an iPad Mini?

What tablet does she have? Keep in mind that this is the Droid Razr Maxx subforum.

Airplane Mode is the best way to approach it. If Airplane Mode is on, it should remain on even if she powers the tablet down and then restarts it again later. She can always turn wi-fi on or off manually. I keep my tablets on Airplane Mode even though they're wi-fi only, because I always wonder if the Phone app (which is still present on Android tablets that can't act as a phone) might actually try to use some CPU cycles.

You could check your network signal on your phone like this

When it isn't solid green, the battery runs down a lot faster because the radios are constantly searching for the signal.

ok u r right ...but it cannot drain battery so much that it comes to 30% when fully charged and no use.And one more thing ..a few days later...when i charged it 100%...and leave it .... it drained maximum 98%...but now just like a water fall....

There must be a rogue app keeping the phone awake. It could be anything really. Usually it's something like Facebook or a widget.

My LG G2 usually loses about 1% every hour while in idle mode

Yeah it could be but i cant find it...Now i start feeling either there is a problem or phone is refurbished.

Hi!

I ran into same problem. Cell standy drains battery too much. I have samsung galaxy core prime (android 4.4.4). I changed LTE / CDMA to GMS / UMTS.
Seems to be working already. I post later the results.
