I have two phones that did this, one is a Huawei Honor 5X factory unlocked.
Other phone is ZTE ZMAX Z970 from T-mobile.
I will just talk about the ZMAX as it has been misbehaving the most in the hands of a person that is almost never using it. (My mom who shys away from technology)
Short Scenario:
The units of measurement are not a typo I really mean Gigabytes and Terabytes, not Megabytes or Kilobytes.
ZTE ZMax Z970 chews through over 1TB of data in less than a month
Typical use before this issue was 1-3Gb per month. Issue started suddenly and ended just as quickly before I realised what happened.
Mother complains of poor battery, unresponsive phone, trouble placing calls, etc for 3 or so days. In hindsight I now know why it was performing so bad, phone spent all it's resources moving data around on LTE and WiFi. But Why????
Hardware Details:
T-mobile locked ZTE Zmax Z970
Android Version 4.4.2, Baseband version P892T57B01, kernel version 3.4.0-g9b6969a-00469-g20d00e4 zte-kernel@Zdroid-SMT. Build numberZ970V1.0.0.B22. Hardware version wwdB.
Scenario Details:
This Zte phone always ask for update, never done it since purchase (around Oct 2016), never had a problem before this month.
Zte storage is about 1/2 empty. Phone barely used. Mostly web,skype,youtube. Phone is used by my mother, she barely touches the thing, does not own social media.
Data traffic management on moms phone shows "GOOGLE SERVICES - Miscellaneous" used 630GB by itself on LTE (June 7 to 13) and another 711 GB on WiFi (May 24-June21 for wifi), basically within the last 30 days.
Other google services showed very little usage, location 12.5 mb, Google Cast 0.27mb, Google Games, Data Mngmnt, Contacts,Fit, G+, OTA, Backup, Wear, Nearby. All those services were 0mb altogether, so not used at all.
T-Mobile confirms usage is EXTREMELY high, 663GB on LTE from May 15 to Jun 14 which is a bit more than the "Google Services" background app used during that time, I suppose that 663 is the total.
Something happened between those dates. Can anybody figure this out?
P.S.
I know the ZTE has not had it's OS updated BUT, the Huawei also did something similar and it is fully updated always. Never had issues before my typical usage is 20-30Gb a month.
Huawei consumed 260GB in the same time reference. I don't think I was even in town when this happened. So the phones were not even in the same state. I was in WI, mother was in IL.
