E5 has started to die at around 30% battery

DarkFire — Tue, 29 May 2018 16:08:28 GMT

Over the past couple of days I my phone has been dying frequently.

During my work days the phone is idle most of the time and I can usually have a fully charged phone in the morning and still have around 40% by the time I'm off to bed however lately I'm lucky if my phone lasts till 4pm before turning off.

i have noticed that when my phone is in use, the battery has started to drop rather rapidly and the once it gets to around 30% the battery level immediately drops to zero and powers off (it literally did it while I was looking at it). It doesn't let me power it back on until it's charged enough.

ive also noticed that if I use it for even a moment while it's on charge the battery still drops. Anyone have any ideas as to what's happening?

Hi @DarkFire;

First of all what is your battery condition under Service Menu>Service Tests>Battery Health (dial *#*#7378423#*#* for the Service Menu)?

Test also the phone beahviour is Safe Mode to see if same thing happens (https://support.sonymobile.com/global-en/xperiaz5/kb/0231018877589a7b01429399b11c00699b/)

Xperia E5 battery life

Last week or so my battery life has dropped from a day's usage to just a few hours. Anyone else had a similar issue? I'm wondering if it could be a software issue as performance has dropped off so quickly? Phone is 18 months old, might be time for a new one...

Battery Drain

I have always have issues with my phone coz of how it drains battery. I can't even play music or use it for other apps like games etc. The phone has been to the Xperia repair Centre twice and no solution but sorrows.

I also reset to factory default, this made a slight improvement but I think it has to an update on the software which is causing the issue

I have the same issue for about the last week. Phone suddenly drains, especially from in the 50 percent range, drops down rapidly, only lasting for less than a day on full charge Today went from 19% to switching itself off within 2 minutes. Takes hours to charge and feels very hot. Has taken 4 hours to get to 80%. It is just around a year old so can't believe it needs to be replaced yet?

How long is the battery test supposed to take? It's currently been going for over 16hrs and I'm not sure what's happening. Am I supposed to leave it charging the whole time or am I supposed to let it test it without charging?

Sony experia E5 over heating and bad battery

phonyE5 — Thu, 31 May 2018 09:30:43 GMT

My Sony E5 battery just drains When I go online it gets so hot the screen has visible burn marks on the screen. It is obviously a manufacture fault as it seems to be a problem with a lot of Sony phones. Just wondering why Sony are still allowed make phones when they are a danger to the public

@DarkFire;

What battery test are you talking about?

The battery test in the service menu is immediate, it shows you instantly the battery condition.

To test the device in safe mode use for the same time you normally will detect the problems in the device, if nothing happens in that time it means that is some app (or several) that are causing the problems.

I'm using the test in the service menu. As soon as I clicked it it said that it would take several hours, it's currently at 23hrs and if I try to select back it says " warning test not yet finished". It's giving me all the information about voltage, temp, plug type, start and current %, and it says the health is good.

@DarkFire;

We are not talking about the same service menu>service test (*#*#7378423#*#*), in there you should get a read in (uAh) and the information if the battery is good or not and if it needs replacement.

This is what comes up when I dial the number. Is this not it?

I also keep losing my Bluetooth connection for the last couple of days, very frustrating

Sylvester05 — Thu, 31 May 2018 17:49:04 GMT

Is it possible someone from Sony help us out as this is affecting too many phones especially it appears that an update could be the problem as the issue appeared from nowhere. Batteries are draining rapidly ruining the use of the phone

Re: Xperia E5 battery life

Oli11 — Thu, 31 May 2018 20:05:55 GMT

Thanks for your replies, its made me think this is likely to be more of a software than hardware issue. I was considering a new battery but I guess the same thing could happen with a new battery and the phone isn't designed to easily replace the battery. I will try a factory reset when I've checked I've backed everything up.

It will be interesting to see if/how Sony resolve the issue. In the mean time I think Im going to have to get another (non Sony) phone as charging twice a day is not practical!

Sylvester05 — Thu, 31 May 2018 20:27:20 GMT

You are correct I have had the battery checked out and there is no fault with the battery so it would a waste of money to change it. Sony will wash their hands of this fault as they are only concerned with selling phones

@DarkFire;

That shouldn't be the battery health test in the Xperia Z5 service test (I even went looking in my old Z5 just to be sure), anyway the Xperia Z5 has as new a 2900mAh minimum battery, so probably your device doesn't have the full capacity in your battery now, something is not right.

Did you also tested your device in safe mode?

I hope that it can be sorted, I can't change this phone for at least another year due to my contract

Sorry no, I've been stupid. My phone is the e5 not z5. Still not sure whats wrong. I'll try safe mode next
