Battery drain after Lollipop.

[KysCoops]

Hi All,

Since upgrading to lollipop around 2 weeks ago on my Z1 compact, my battery life has been terrible. 2 days after the update and frustrated with battery life, I connected to the PC companion software ready to factory reset, to find another update, which has stopped the Facebook app destroying my battery, and actually seemed to fix my battery issue as I went back to getting 2 days out of a charge. Sadly this only lasted not even a week.

The last two days have been the worst. After work yesterday it ran completely flat (no warning - and phone barely used). I charged it up to 100%, disconnected the charger, and went to sleep. I woke up in the morning to 8% battery - the phone was IDLE. The next charge, my phone told me it had fullly charged, but when I disconnected the charger, it was only at 96%. It took another half an hour to reach 100%, which was at 1130am. By the time I got home at 630pm, my battery was down to 35%. It is now almost flat and I am going to have to charge it for the 3rd time in 24 hours.

Checking battery usage, Android OS, Android System, Telstra (carrier), and Setup Wizard are all excessively draining the battery (the Android OS is the worst one with battery usage at 30%). It won't let me disable any of these, I can force stop only the Telstra one but it starts again straight away.

Does anyone have any suggestions? I am so frustrated by this, and my phone is unusable at the moment.

I started using third party battery monitors to see what is eating battery. I expect more details than when just using standard software in the settings of my phone.

What did they come up with. 

This morning as soon as I unplugged from charge the battery dropped to 99%. Then another 9% rapidly disappeared. The only thing the inbuilt battery monitor reported as using power was Android OS, which is always the biggest drainer now. The rest went somewhere, either its a fault or the power is being taken by something else. 

Oh well, time to bite the bullet and reset it all.

I did three things:

1.) Yesterday I force stopped Google play, deleted its data and managed to uninstall the latest version (I think it was 5.9.12). So I was left with older version of Google play and actually Google play disappeared from the list of installed applications as well as its icon on the main screen. Later on I re-installed Google play 5.9.12.

2.) At approx. 62% of the battery I turned the phone off and left it on its charger till morning.

3.) In the morning I installed one of many available battery monitors to see what is eating the battery. I didn't touch the phone for most of the day with only short instant messaging over wifi and mobile data connection to see what is eating the battery in almost idle state of the phone. Now it is evening and I still have 93%.

Here is the picture:

As you can see, "Phone radio" is active all the time and is using most of the battery.

I'll keep monitoring the situation during the working week when I use mobile phone far more extensively.

There are also other battery monitors available which list every process and application that uses battery.

Situation after 31 hours since the last battery charging cycle:

The overall situation is better than before. I don't know for how long. I'll keep monitoring the battery usage.

Interesting. I am trying a reset at the moment, but the PC Companion backup tool keeps failing...

[XperiaNow]

I didn't use backup tool of any kind. I always backup manually important data, and don't mind setting applications again from scratch once I reset (factory reset) the phone or re-install the update via PC Companion.

I did another thing. I turned on auto brigtness control and manually increased brightness almost to the max while auto control is still active. By doing that I allow software to control the brightness according to user's environment while the screen is not so dark as I manually increased the brigthness. It sounds silly, but that's the way it is. Reducing brightness is often recommended as a remedy for battery drain.

Well that was a roller coaster ride. After  spending a long time with failed backups I eventually got a limited one to work. Then I set about repairing the installation. Which failed too, leaving my phone unable to turn on properly and crashing Windows 10  every time I started it. 

Through experimenting with plugging and unplugging things at various points I eventually got the PCC thing to start up and actually reinstalled the software. 

The phone is much better overall now, and battery drain seems to be giving me about 4min 30 secs for each 1% of battery while browsing. Its also not getting hot. 

I dont think this is as good as it used to be, but I'll take it.

Today I used Google play again to update some installed application. I also used mobile data, so I'll see if it makes a difference or not. Last two days were great, the battery was behaving good.
