Android 5 has ruined my phone

Sland — Fri, 01 May 2015 23:19:01 GMT

I bought the Z1 Compact because the battery life was amazing. At the end of a day (about 7pm) I would still have over 60% battery life. Since upgrading to Android 5 my phone is worse than an iPhone, I am down to about 30% by 5pm. I have pressed the orange button by the sim, I have enabled every power saving option going apart from the ones that completely castrate the phone and there is no improvement. Not only that but it seems to only run 1 core of the CPU making it completley sluggish and frequently non responsive. Android 5 an upgrade? No way it is 10 steps backward. Please provide detailed and accurate instructions to allow me to revert to 4.4.4.

Oh dear, although I can't say that I'm surprised, I could be wrong but I think that you would require to root your phone to go back to Kitkat.

I like this phone too because of its good battery life, but I am staying with Kitkat purely because it works a treat.

You don't have to root to flash your phone @cobbler

@Sland

before downgrading reinstall lollipop with PCC > make sure to delete everything on the phone then wait couple of days, your battery life will improve

PC Companion (PCC)

Bridge (for Mac)

@uliwooly So flashing the phone enables it to be downgraded then?

I thought to flash the phone needed to be rooted?

Flashing the phone will update or downgrade the phone. rooting it's different.

Both ruin the warranty so never advisable.

@cobbler

That's not true, in some cases it could.

I think that you have a problem with your phone because I have the same phone and I am satisfied with the performance and battery after the lollipop upgrade!some times my phone last more than before!

Hi folks.

My apologies for the lack of response to this thread but I've been unwell.

In the end I decided to wait for a patch and tonight I received an upgrade to version .270 and it has made a huge improvement. Too early to say anything about battery life but the horrible slugginishness has gone.

Many thanks to all of you who took the time to respond to the thread, it is appreciated. Cheers.

Hi, any updates on how the .270 firmware is to the battery life?

Became a little wiser since the last lollipop update and have learnt to wait a while to see the reviews on the net effort accepting firmware updates from Sony 😛

It has improved a lot but is not back to 4.4.4 levels. The main issue seems to be that, although I have stamina mode enabled, wi-fi is not being turned off properly when the phone is in standby (see bars at bottom showing wifi on when phone not awake)

Wifi is not turned off in Android 5. It is used as location provider, even if wireless connection is dropped. For the same reason there is no "Location based wifi" on 5.0.2 in Xperias.

The graph itself look pretty normal, at least in areas where screen is on. What bothers me is that you have much of background activities (from apps) that discharge your phone when you are not using it.

Looking at my Xperia I can say that Lollipop battery performance is on par with that on 4.4.4. At least as long as Lifelog is not installed on the device.

Here is a screen shot of the stamina mode screen. As you will see, if you bother looking, extended standby should turn off wifi WHEN THE SCREEN IS OFF!

Additionally, if you care to look at the "apps active in standby" option, you will see that NO APPS ARE ALLOWED TO BE ACTIVE when the phone is in standby. Thank you for your input.

Yes, but dropped connection does not mean that the wifi module is off. It is not. It depends on GPS settings.

As for background activity. Even if any app is not allowed to run in stamina mode (it does not cut apps off - it shuts down network access for apps) some apps may wake up phone for bluetooth activity, location scanning (I'm looking at Google Now and Location History feature - big battery hog). Google Play Services cause some background activity even when not allowed to.

Stamina mode does help but is not cure for all troubles. I'm sure that some kind of location service is doing it's background spying job and that is why you see what you see.

Man, if you don't know what you're talking about just don't reply and let others who know speak! It DOES cut off apps and the wifi and data ARE disabled! I had problems with apps that don't have access to the internet at all, but when stamina was active they were not working, and I had to add them to the exception list to make them work!

Where are the Sony officials? Why don't they give some responsible answers and let users answer on behalf of them???

Bluetooth is not turned on, Google Now is disabled (a bit like yout brain). Look, you think you know what you are talking about but you don't. Please just go away and don't add any more rubbish to this thread!

That wasn't to nice. But as you wish... help yourself. Sony officials can be found by clicking Xperia Care at the top of the page.

Stamina mode should shut data off and prevent phone from waking up. _SHOULD_ but I know from my phone that is not always the case and Lifelog is great example for that.
