Cell signal search is killing my battery

Every one in the community know that I love complaining. Well today I am complaining about the cell coverage and how is it killing my battery. Any one can hell me out with that. ?

So I having been monitoring my battery and how is it getting drained like Niagara falls every day. 

After looking for culprits I seem to find that the radio search is mostly at fault.

As you can see from the colors it is always on the orange and the red; and out of service for half of the time. 

I am going crazy as Greenify is bring some of my sanity back but I do appreciate of you guys had some tips on how to deal with this especially at home where I can only get a max of 2 bars of either LTE or WCMDA. (And that when I am near the window in the 2nd floor)

Also I did start restricting synchronization and  android system but it seems that a combination of both bad cell +WiFi brings it downhill quicker compared to when connected in the university per example (good cell coverage always on the green)

I am on Android 6 and I do appreciate any suggestions

Thanks

Re: Cell signal search is killing my battery

What phone are you running?  Android 6 is pretty good on battery usage.  At home and in my office, I get between two and three bars in LTE and my battery consumption in standby is excellent.  The battery drains at a rate of about 1% every 3 hours.  I run greenify also with xposed framework to enhance deep sleep mode.  

 

Apart from the unusual cellular disconnects, android system power usage is very high.  That's an indication that there are too many wakelocks preventing the phone from entering deep sleep mode.  If your phone is rooted, run a wakelock detector to see which apps are keeping the phone awake.  Otherwise, run gsam battery monitor to see which apps are power hungry.

Try setting your preferred network to 3g instead of LTE. I find their 3g signal is a lot better and 3g may use less power then LTE too.

It could be time for a new battery.

Are you on Custom Rom?

Re: Cell signal search is killing my battery

The standby time looks perfectly normal when signal is red, then all of a sudden after a gap in the graph (which indicates you restarted your phone), the battery started going down drastically.

 

It shows from the list that Android System is the biggest user of battery during that period by far. This indicates that the cellular signal is NOT the cause of your battery drain, but something that has gone wrong in the OS. Seeing as you are using a custom/modified ROM, it could be practically anything. Android System battery drain in even stock ROMs, never mind custom/modified ones, are more often than not impossible to track down the exact cause of, as the battery stats screen is very unspecific in telling you what it is being caused by.

 

In most cases however, this issue can be solved by doing a factory reset. If you don't want to do that, you can try going into your recovery and clearing cache first. Keep in mind that once you leave your recovery after clearing cache, you will be greeted with the "Android is starting... Optimizing app X of X" screen, so if you have a lot of apps installed be prepared to wait a while.

Exactly my thought, it could be anything when you use custom rom. I switched multiple ROMs and Kernals to find better ones that suits me. 

Try the best kernals like Franco or ElementalX. Before trying, always backup.

Re: Cell signal search is killing my battery

Yes I am running Android 6, and adding Greenify also with xposed framework going for aggressive dose and I cant deny that it is indeed making some difference. 

I did install gsam battery monitor and now I am trying to understand how to work with it, thanks for the suggestions.

Unfortunatly, at home it is no difference. But I do that in other areas and it works

XD, indeed, it is new... in fact it is a new Extended Battery

Spoiler
[7800mAh]

So it is a lot of juice that do not hold for the day

 

@NDesai , yes it is a Custom  ROM this tme I went for something really light, no more of that Touchwiz Ultra personalisation, I am on a pure Android now, it is a lot quicker and stable , it is based on CM , So I would imagine that it is good (at least frm my previous experiences with that) ,

Thanks, I will keep that on the last resort
