Default Battery drain in airplane mode (> 1%/hr)

OS: 4.4.2

Several of us have noticed a significant battery drain even in airplane mode, > 1%/hr . Typically, we've seen >10% discharge overnight.

Here is an example. Put it in airplane mode all night and had location services disabled. Here's the result, > 1%/hr drain. This was with Google Play Services 4.1.





This thread is to collect our observations, experiences, and hopefully find a resolution to this annoying issue. The MOTO G should, in theory, have bad-ass battery life.

Here are the further steps I took in determining a root cause.

1. Do a factory reset.
2. Full charge, leave it on charging for an additional 30mins beyond 100%.
3. Allow play store to update all built-in apps.
4. Add google account, and select the usual items for sync (no location!).
5. Disconnect power cable.
6. Discharge down to < 10%.
7. Full charge
8. Activate airplane mode.
9. Disable location services.
11. Lock screen
12. Disconnect charging cable.

OS: 4.4.2
Google Play Services: 4.0.34

So far, 5+hrs and no decrease in reported battery level. It is still showing 'charged' (i.e. it has not dropped to 99% yet).

Next test: Determine the effect of updating Google Play Services to 4.1
1. Update Google Play Services to 4.1 (newest one)
2. Use normally thru the day.
3. Fully charge phone at night.
4. Activate airplane mode.
5. Disable location services.
6. Lock screen.
7. Disconnect charging cable.

Google Play Services 4.1.31 was not available on Google Play for me. Here is the apk:

So when you upgraded to kitkat where you still on goole play services 4.0.34 ??

And if so where did you get google play services 4.1. If it was as an update on the playstore then fair enough but if you have downloaded it from elsewhere then maybe the 4.1 is not supported on moto g running kitkat etc. ie are you creating an issue yourself - of course we dont know yet if google play services is the cluprit anyway.

From your above post it seems your battery issue is fixed with bog standard kitkat, ie you say 5hrs and no drain yet.

Unfortunately, I can't be sure when I noticed the >1%/hr drain - whether before the google play services 4.1 update or after. The update that I installed was signed from Google, and the whole point of it was to decrease battery drain. I find it unlikely that it was the root cause of the battery drain. But, as you can see in my above, I plan to run an experiment to determine the effect of google play services 4.1 update.

I got the google play services 4.1 .apk from here:

Btw, 7hrs, and it is still indicating 'charged', and has not gone down to 99%!

I noticed this issue last night, and that was with Google Play Services: 4.0.34 installed.

In installed Google Play Services 4.1. After going thru the same procedure, I am down to 97% after 3hrs using airplane mode and location services off the whole time. Perhaps Google Play Services is the culprit. However one of you mentioned that you observed the drain even with 4.0.3x ... strange. Maybe there are two difference phenomenon in effect? Will let it run some more to confirm the drain rate - then will revert to 4.0.3x to complete the A-B-A test .

Did a factory reset and the usual basic setup. This time around, my phone was automatically upgraded to google play services 4.1. I found the .apk for 4.0.34 and reverted to that. Then charged to full, and enabled airplane mode and disabled location services. After 2+ hrs, it is still at 100%!

I'll let it run all night to confirm. However, from the looks of it, it seems that google play services 4.1 is causing a ~1%/hr discharge in airplane mode with location services disabled. WTH google? I thought 4.1 was supposed to deliver *better* batt life.

Anywhoo ... will report in the morning.

I'm getting a 0.8% drain with everything disabled but 2G. Strange as this doesn't normally happen with me. Can't find a way to reduce it...

I had the same issue. With Google Play Service 4.1 I have 1% in 8 hours at airplane mode now. For me the manual upgrade did the trick. Battery seems to be better over all.
