Update 23.5.a.1.291 battery optimization

DiegoSalazarG — Fri, 05 Aug 2016 14:11:28 GMT

So today my Xperia Z3 updated and a screen saying something like:
The maximum amount of charge has been reduced to optimize the batter. Check ... to change it.

Then another screen came on top of it so I couldn't read the previous one carefully but it looked important because my battery went down from 52% to 40% after 5 minutes of update (this must've something to do with it).

What was the full message cause I couldn't find anything related in Settings-Battery optimization other than the return of stamina mode.

Hi @DiegoSalazarG,

The setting for this can be found in Settings > About phone > Status > Battery optimization.

Your phone will need to restart if you turn the feature off or on.

What this feature does is that it adjusts the amount of charge to increase battery lifespan.

Where will arrive update for The single with tv?

What does this mean? Do you mean the phone will not let the battery be charged to 100% (although I charged overnight and it was 100% in the morning), OR that the battery will not be "rapidly charged" if say I plug in a 2.0 mA charger? Sometimes the explanation Sony provides is vague.

This is what i think..

Our phone has auto-stop charging feature when the battery is "full"
However, the phone determine the full battery from it's voltage. For example 4.2V ~ 100%
and when our battery reach this voltage or percentage, it will stop the charging.

BUT, after we use our phone for some months or years, the battery condition cannot reach this voltage anymore.
For example, 4.1V is the max voltage it can reach
That makes our phone to continue its charging even when the battery is full (at 4.1V) overcharging

This Update may change the "full" battery scale to 4.1V to prevent over-charge to our battery so that we can have a better battery condition.

But what about the voltage when charging? Will it make rapid charging slower?

Something seems to be wrong. I have the d6603 and just applied the update. It's been at least 10 or more minutes and after two phone restarts, my battery still says 100%. Surely it should be down the mid 90's by now.

ikramkhasim — Sun, 14 Aug 2016 15:10:41 GMT

I got that too after charging overnight. It stayed at 100% for 10 minutes or so with normal use until it started rapidly declining. This was with charging optimization off. So I'm still confused about what either (on or off) does.

Fexjo — Sun, 14 Aug 2016 15:13:10 GMT

No, the charging happens when there is a different voltage between the battery and the charger..
For Example, the battery 3.6V ~ 0%, and the charger using 5V. The voltage difference will still the same (1.4V) and will stop when the phone orders to stop the current at 4.2V (default)

This update only change the voltage state of 100% (ex: at 4.1V) and scale it down. So our phone will only use about 90% of its battery capacity, but scaling it to 100%
That makes our phone charging quicker, but also drain faster.. just like having a smaller battery.

But, this options is used to prevent overcharge to our battery so i suggest we use this feature (if your phone aged >6 months)

*quick charge only supported on Japan version*

100% for a long time can be happen when you battery is at good condition (probably aged <6 months)
So when the threshold of 100% is at 4.1V, your battery is still at 4.2V that explains the 10 minutes extra

OK after about 3 hours the phone is now at 97 percent with minimal use (texting, Google maps) so far. I'd say the update has improved my battery life without turning on stamina mode yet. I've had this phone since June 2015

Not sure if mine is considered Japan version. It's 6653, and if I plug in a magnetic cable with a high amp, it will say "rapidly charging" on screen.

Fexjo — Mon, 15 Aug 2016 05:02:15 GMT

QC 2.0 from Snapdragon that uses 9V charging only supported on Japan version and through micro usb cable..
Magnetic cable is not supported QC.
And i forget how to identify the Japan version
Yes, we can only use rapid charging (5V 2A charger) and it's still slow..

*QC (Quick Charge) 2.0 ~ 0-60% on 30 mins

@CyberChulo Actually this update improves battery-cycle, not "battery usage time". So probably you you'll find your device drain faster.
That is why it says "This may shorten the usage time of your device"

ikramkhasim — Mon, 15 Aug 2016 05:57:41 GMT

Yeah, mine's not the Japan version then. But the reason I'm asking is that I'm still wondering if this option will make charging slower. For instance I had it on while using Waze and was charging it at the same time. Previously before the update, the battery would either charge slowly or be maintained at the same percentage (just because GPS and screen is always on). However, after the update and with charging optimization on, the phone battery kept draining while charging. I also noticed that it estimated a full charge from 40% to full at about 5 hours when on the magnetic dock at home, and usually it only takes a couple hours.

CyberChulo — Mon, 15 Aug 2016 09:06:28 GMT

It's been 12 hours so far and down to 87%. I'll leave it uncharged and continue to use it regularly today while travelling to work. I'll let you guys know how it goes. By comparison, before this update I would have been down to 65 to 70% by now.

Re: Update 23.5.a.1.291 battery optimization

ikramkhasim — Mon, 15 Aug 2016 09:08:55 GMT

12 hours and still at 87% is something I haven't achieved before, unless I don't touch my phone at all!

Re: Update 23.5.a.1.291 battery optimization

CyberChulo — Mon, 15 Aug 2016 10:03:37 GMT

Lol. To be more specific. I just woke up after 12 hours of sleeping. It was down to 91% when I fell asleep. Usually the battery will go down between 65% to 70% when I reach for my phone in the morning. Since this is way better than before the update. I'm going to assume it will last longer through normal use during the day. We'll see what happens today.

Whew! I was getting alarmed there.

Re: Update 23.5.a.1.291 battery optimization

Fexjo — Mon, 15 Aug 2016 16:02:37 GMT

hahaha
@ikramkhasim it shouldn't be slower..
i'm concern about either your bad battery condition, or your magnetic dock / cable..
My suggestion is to download "Ampere" on PlayStore and see your charging current.. mine is about 1.2A when using my Magnetic cable
And see your car charger, i suggest you change your car charger to the one with 5V 2A output (USB slot on car usually has 5V 0.5-1A)
because i never had draining when using waze and charge at the same time..

@CyberChulo my friend, i think your phone has problem app before the update.. hahaha, because mine always down about <5% in the morning after i sleep 8-10 hrs
