I'm fed up a bit for my Z3 C battery life. This is my second query regarding battery life.

Does keeping Mobile data and Whatsapp running ON even in standby mode drains the battery??

I usually get just 1 or 2 whatsapp messages in an hour or two.

My phone settings-

Always turned off my wifi/ bt/ nfc/ gps/ location tracking/ autoupdates etc. & everything you can think and suggest.

I use only stock custom wallpaper and no live stuff. No widgets. No sd card inserted. With only two homescreens with just 2 shortcuts on each screen.

Have disabled apps which I dont use.

Stopped services of apps which are no longer needed.

No auto sync enabled for any app.

Display brightness is at 30% all times.

*****************************************************************************************************************************************************************

I use only these 3rd party apps-

Status bar mini

Network monitor mini

Greenify

*****************************************************************************************************************************************************************

My daily Z3 routine-

At night while going to sleep I turn off mobile data, turn on airplane mode and turn on stamina mode. (12:30am - 9:30am)

Manually Force stop apps which are on. Use Greenify to exit/stop apps.

When I wake up the next day battery is down by 4-5%.

During day, phone runs in normal mode without any stamina activated. (10am - 12:30am)

The Low-battery mode seems useless as it does literally nothing.

Also, as soon as the battery is 100% charged and if I use phone for even 5 mins the battery immediately drops to 99%, so is this normal??

Even if I capture 5 photos in stock auto mode the battery drops by 1% or 2.

I reboot my phone once a week or in 10 days or when need arises.

Ram utilised is always 1gb. But I dont feel any slowness for any app or my phone usage.

So inspite of all this STRICT following what I get at the end of the day is just 1.2 days battery life.:smileyshame_on_you:

Again I dont watch any movies or play games fearing my battery will deplete in no time.:smileyshame_on_you:

So basically I'm using my Z3 as a battery monitoring unit and is 85% on standby mode. So when shall I use my phone the way it is designed for???

I have read people using it for occasionally playing games and watching movies, light surfing, calling and camear and it still lasts a good 2 days. So where I'm going wrong here?

I use 2G/edge network as 3G isnt available for my operator in the city I reside.

Charging the phone to 100% from 14% takes 3 to 3.5 hours.

I have already repaired my phone using Sony pc companion and also did a factory reset as well but this issue has been haunting me.

Sony center says the battery doesnt need any replacement as its still healthy and so is my device.

The phones service menu also reports battery status as Good.

I dont know when is Lollipop gonna be out for Z3 but I fear updating to Lollipop as it may pose more serious issues than doing any good apart from usual GUI tweaks & updates.

But just wish that lollipop brings in more relief to Z3 batteries and operations.

I have the same issues. Screen takes up lion share if battery life such that all other settings become irrelevant. I'm down to 90 after 10 minutes on facebook. Everything is optimized as suggested. It still gets home with a respectable 50% left but that's from spending 6-7 hours in my pocket at best with an hour browsing or texting.

I had the same problem with my Z3 compact. The battery suddenly start to drain rapidily even on idle. I tried everything including resetting the phone and repairing the phone with sony bridge for mac. Nothing worked. After some investigation I found that the media app was trying to index corrupt files on my SD card. As a result it was continually keeping the phone awake. I tried to delete/format the SD card but couldn't. So I removed the SD card. It worked!. My battery life is back to normal, I might say even better. Hope this helps.

You removed it for good? or just for a while?

If I depend on the card, I can't remove it permenantly in order to fix the drainge issue, doesn't seem like a good solution.

As gpathman says, corrupt media files may cause the phone to use more battery as Android tries to index these files but it could also be that the SD card is damaged and needs to be replaced. If removing the SD-card helps, first try to reformat the SD card but please note that this will delete all files on the SD card. If formatting the SD card doesn't help i recommend that you try the phone with another SD card to see if it might be the SD card that is damaged.
