[Q] z1 display drainage - Xperia Z1 Q&A, Help & Troubleshooting

Hello xda members
Iam a huge fan of Sony and Xperias
I love my z1 but my battery doesn't last the hole day without charging.
So when I look at my usage I see that my display has taken 50% of my power
Is this a hardware or software problem?
Please help

Its normal, becase our display is LCD-TFT which is known to be power hungry.
Z2 and Z3 have IPS-LCD which is power efficient, that is why they last a lot longer on battery instead of z1.

Ok thanks man much appreciated

[Q] Added value of Stamina

I bought my Xperia Z almost three weeks ago, and I am very happy with this device.
The device showed me that I had a few hours left on battery, but as soon as I turned on Stamina-mode it told me I even had a few days left! (But it never really gave me these few days.)
Now I have installed CM10.1 on my rooted Xperia Z, I lost Stamina. But for me it didn't really have impact on battery life.
Battery life on my rooted CM10.1 Xperia Z is still very good.
My question: Was Stamina really improving battery life, or was it just adding placebo?
yes it's improving battery life when in standby mode(screen is off / not using phone)
I personally think Greenify does a much better job. Without needing to turn off data.

It depends a lot on your usage patterns. If you use a lot of mobile data, it makes a huge difference. It literally turns off data when the screen is off. So it improves your battery life by that much. However, over WiFi it didn't really make much of a difference. Also, if you wake your phone up every few minutes to text, it seems to only hurt the battery as it keeps the phone awake for about a few minutes after the screen is off. So you're essentially reducing the idle time of your phone. So it's all up to how you use it.

Low battery voltage?

Hello!
I have an 4-year Xperia SP C5303, with Candy5 v4.0-20151015 (I know, didn't update - OTA isn't working and I'm lazy), and recently I found a very strange issue with it. Whenever the smartphone goes down to 40% battery or lower, there is a chance that it will not wake up, plus there are accidental all-system ANRs.
I think it's battery which lost it's capabilities over the years and does not supply the required voltage under load. What do you think? What would you do? Is there a point in investing into battery replacement, and can I replace it, maybe by disassembling the smartphone?
I think after all this long time using candy ROM, all you need is recalibrating your battery.

Poor battery life when using as hotspot

When I set it as a hotspot the battery life drains quite fast. In 6hours the battery life is 20%. Where as my old phone sony xperia z3 compact lasted longer... in 6hours it was only 60%. Why is battery life poor on P10? anyway to improve battery life when using as hotspot? I tried the battery saver option but it still gave same result
Hotspots use alot of battery, thats just how it is.

But how come the sony z3 compact can last longer than p10 especially when the z3 has a smaller battery pack 2600mAh

Need help about battery and signal

Hello guys im new here and also a noob, i just bought this phone and i have a problem with the signal on my phone, its only has 1 bar when i entering a building or even lost, is this normal or software bug or my phone is broken? The phone came with android 10 already, and also i noticed my battery life is not good at all, its draining pretty fast, am i got a bad phone, i dont know if any of you guys had this problem like me? Please share your opinion with owning a XZ3. Thank you and sorry for my bad english
When you have a Sony phone with a 3300 mah battery and a 2k resolution display, you can't expect much in terms of the battery life.
