Gmail massive battery drain

[Slion 1,200]

A couple of days ago my Pro1 started seriously overheating and draining its battery. Rebooting didn't help. After investigation I noticed it was constantly using network bandwidth both upload and download. Settings battery usage was reporting Gmail as being most greedy. Network monitoring tools were in fact showing some Google Service was responsible for that traffic.

Turning off auto-sync in Gmail fixed the issue. Battery life is now awesome with the downside that emails and personal info don't sync automatically, obviously.

I only have two accounts in Gmail, namely Google Gmail and an Active Sync account. Only the later is setup to synchronise.

This is a problem I've seen before on my venerable Samsung S7 Edge.

Sounds like yet another Google app that should be avoided... 🙄

For what it's worth, I haven't noticed any similar issue, but only use one gmail account.

I think if this was a common issue, google would be on top of it.  So it's probably a you issue.

But on previous device I used to use K-9 for years and was always happy with it....

Easier said than done since I'm using ActiveSync Provisioning. My understanding is that Gmail is just the frontend using a bunch of Android backend services doing Personal Information Management at the platform level. Things like Contact and Calendar synchronisation.

From there flows a few questions:

• Is ActiveSync Provisioning implemented by those Android services or by Gmail?
• Are those apps you mentioned just using those Android services or implementing their own stacks of protocol?
• Was that bug I'm facing really caused by Gmail app layers or is it in fact caused by those Android PIM services?

Am I holding it wrong? 😁

I am not sure if that information is useful at all, but I recently had the Google Photo app causing overheating and battery drain on my Priv. So maybe there currently is some problem with synchronisation of Google Apps in general?

I have 2 Gmail accounts currently configured on my Pro1 and don't see the issue.

I've been using Pro1 for almost 2 months without getting that issue either. I think until then it had been possibly overheating a couple of times but a reboot always fixed it. This time it was really stuck trying to do something dumb or just slurping my data 🤔

To be fair and as mentioned in the first post it's an issue I observed on well-known brands flagships over the years. Though in the few months I used a Huawei P30 Pro it never exhibited such an issue.

Just added a new feature to Fx Service to workaround this major issue, see:
