Battery drain through email app/exchange

[dphoffmann]

Hi all,

I have the s25 Ultra and am quite happy. But I realised that Samsung Mail or Gmail (tested both) are by far the apps that drain the battery most if I don't use my phone a lot. It is even more than play services, which is usually high when the phone is just in standby. I have an exchange account set up to sync contacts, calendar and mails. 

With OneUi 6 I didn't have this issue. 

If I uninstall/disable the email apps, there is no issue. 

Any idea what causes this? Or could it be a bug with the exchange protocol? 

Thanks for opinions or solutions.

Hello @dphoffmann 

I use the Samsung email app exclusively for all my email accounts. 

For example today from 5am to present time of writing this reply it has used >

Maybe long hold on the email app icon and tap on i and then storage and then clear cache as a first step.

Hi! How odd. I would suggest going to Settings > Apps > the email app you're using > Force stop > Clear cache. See if this fixes your problem.

Thank you. I also tried a new installation. Didn't work. I guess that there's a but with the active sync/exchange?

I have an update. The email apps only seem to use so much battery when I am not connected to WiFi.

When I work, without WiFi, the email app is the 2nd highest battery drainer although I didn't open the email app at all.

At home in WiFi it is one of the lowest with 0.2%

Any ideas what the issue could be?

I'm seeing a similar issue. Samsung support are useless. Just hung up the chat yesterday.

If I force close all apps, go to sleep, the email app will drain the battery whilst not is use.

This started since the last of update?

I have the exact same issue. Only started this last month or so. And only had the phone 3 months. Samsung support have suggested doing a full Master Reset but obviously that is a huge inconvenience so is not something I can just quickly do. The phone also seems to become unnecessarily warm
