Z5 marshmallow WIFI battery problem

Drcspynz — Sun, 31 Jul 2016 20:35:01 GMT

Since getting the marshmallow update my Z5 has shocking battery drain when on wifi. It's fine if switched to data. Have tried everything including factory reset. Nothing shows in battery app usage as high drain.

Have seen a very few others online with this issue but not many. Any suggestions?

Thanks that's about the only thing I didn't think to try. Will get back to you with a result.

Nope. Lost 9% in ONE HOUR in safe mode on wifi and I wasn't even using the phone grrr.

I have the exact same problem, losing 45% overnight, the thing is I've become so accustomed to not using wifi now my data ran out, hope the news software fixes this.

A h. Another person with this problem. I can tell you that i have 32.2.A.0.253, which is the latest marshmallow version, and it has NOT fixed the problem

You're not wrong, spent the day with the new software and it's still the same, hope they fix this soon or i might have to sell this and get something else. Shame because it's a good phone.

ok I MAY have it figured at last........iv'e turned off location entirely and the battery usage has been approx 3% p/h

MUCH better...

not an ideal 'fix' however

My location is already off, or is location off in toolbar not entirely off?

Check in system/location

Location will only show up in the top tool bar if its being used by an app

Cheers. I was already off, glad something worked for you though.

Make sure under wifi settings you have " wifi on during sleep" set to NEVER

Made no difference, went to sleep with battery at 100% and woke up 6 hours later with battery at 58%. With wifi off and just using 4g it uses 2%. Bugs are buggers.

Weird. Location off completely - works for me.

Hi @Darbo25,

If it is still doing the same thing in safe mode, you are either experiencing a problem with the firmware, or a battery fault.

To determine which, I recommend you perform a software repair on the handset and see if the issue still persists. If it does not, you should be OK to use your phone again normally, though you will have to restore any of your backed up data (also be sure to back up as it will erase everything). If the issue is still happening, contact your local support team to arrange a repair.

My battery is now shocking after updating the os and i can't get the phone through a day of use without charging. Ironically it's no faster, the WiFi is worse and I could cook eggs on it. This Will be my last Sony device. Loyal customer of 10 plus years off to Samsung. Any help from Sony anywhere?

Darbo25 — Mon, 08 Aug 2016 11:26:37 GMT

I haven't tried it in safe mode but it isn't the battery because if I leave WiFi off and just use 4g the battery is great, i lost 3% battery overnight with 4g on and 40% with WiFi on, I've tried doing a repair but it didn't cure it. It'd be nice if these updates were optional, their was absolutely nothing wrong with this phone beforehand, same with my z3 tablet, not as good since its update that I didn't want.

@Darbo25 & @Chrismin,

If the software repair hasn't resolved the issue the best thing I can advise is to contact your local support team and arrange a repair.

To be honest mate I think it's just there in the software, very similar thing happened with my old z1, it'll probably be sorted with the next update.

Well, I say it again ; killing the location function has completely sorted the WiFi battery drain issue on my Z5.
