Sony Xperia Z5 battery drain overheating

[a00r]

My Z5 cannot last longer than 6 hrs with normal use, it cannot even last on standby for more than 6 hours. I'm hoping it's just a software bug because since November my phone has been working flawlessly. It also changes very slowly and that's on quick charge using the official Sony charger that came with the phone. It won't even recognize on my pc when I plug it in.

My Z5 has been overheating when performing basic tasks. The battery also drains very quickly. I need to charge at least twice a day with normal usage and three times with heavy usage. I returned my initial unit. The second unit is giving me the same issues. I upgraded from a Sony Z3 compact where I reliability got a day and half of usage. Reading different user groups, this appears to be quite wide spread. Sony you still do not acknowledge this issue. I note the launch of the X performance series. Sony please offer exchanges to this phone. Presumably these issues have been fixed on snapdragon 820. Sony time to take accountability.

Hi @a00r,

Welcome to the community

Do you have a third party battery manager installed?

I also notice there are a lot of apps in the background. I'm not fimiliar with all their icons but are there quite a few apps that you have constantly loaded?

I have whatsapp running, the next icon would the messaging app sony came with then the screenshot icon then a recent update to whatsnew from sony icon and then a snapdragon battery monitor app

so far I have charged the battery twice for today, now it's sitting at 22%, it was running flawlessly a couple days ago then after on update bam this happens, I wonder if it's a software issue, although I recently did a factory reset, also I notice the phone gets quit warm when charging, oh and also it does not recognize when I plug it into my pc, nothing happens, I hear the beep and nothing pops up on the phone neither pc, and I can only charge it using the charger

@a00r,

In many cases battery managers actually end up draining more battery than they save, especially on lollipop. They close apps which android will automatically re-open, and the battery manager will close them again and so on. The cycle of opening and closing apps causes a large drain on the battery.

It could potentially be part of the issue. Are you able to perform uliwooly's test again, but with the phone in safe mode?
