Xperia Z2 :: Black Screen / Restart / Battery Drain
Nov 7, 2014
I had been using my Z2 for 1 and a half year. everything goes very fine until dew days ago. It suddenly goes into blackscreen while pressing power button/ power + vol. up does not work. I need to dock/charge it for like few secs to make it "alive". I tried reset phone to factory settings, and it still the same.
Tried repair through Sony PC Companion, but it takes FOREVER to download and i just give up this (I have totally no issue at all with my connection. I was browsing youtube, playing games, scrolling facebook etc. without any internet latency problems so definitely will not be my network problem). Then today, it restarted again, so i tried docking it (it was abt 90% remaining). once i dock it, it displays with very low battery (its like less than 10%).....

Ever since the Lumia Black update, I have noticed significant amount of battery drain while not doing anything.This morning I woke up after 8 hours of sleep and removed my 1020 from charging plate, the phone was warm. That means it was charging the whole 8 hours.
I removed the phone and restarted it, turned off glance screen (location off) and did not use it until 3PM (3 hours after being removed from charging plate) and the battery gauge is already below 50%.

I have purchased xperia z2 last october in India. The phone was all fine until last few weeks. From past two weeks the phone heats up for no reason. Even using whatsapp for half an hour is heating the phone to such an extent that i cant touch it. I cant use the phone for anything now. Keeping it on for more than 20 mins is heating the phone without doing anything. Is this any problem from the recent app updates? Or is somthing wrong with my phone? And maximum battery drain is always from screen.

I don't understand what is happening with my 4 month old XPERIA RAY..I've changed the battery with the new one, switch off my phone and full charged it and when i've starded the phone the state of the battery was 96%. After 5-6 hours with data activated, no GPS, no WiFi, no Bluetooth the phones turn off (0%) Can't believe that's normal.When i've bought the XPERIA RAY, i've 2 days before my battery goes empty... And now the phone is heater than before.Is XPERIA RAY a big s**t like my first ps3?

I want to get a discussion going to try to figure out what's causing the massive screen-off battery drain on the lumia 950 (AT&T). I don't believe I'm the only one experiencing this, but here's some background:
Phone has windows hello turned off, hey cortana on, glance screen set to turn off at 15 min. Quiet hours in effect 10pm-8am. Location, cell, wifi, bluetooth all on.
The results:
Charge to 100% and let sit overnight -- first night, around 7 hrs long, it drained to 87%.
Charge to 100% and let sit overnight -- second night, around 9 hours long, it drained to 67%.
Charge to 100% and let sit overnight -- third night, around 7 hours long, it drained to 90%.
My app background permissions have been tinkered with when i first got the phone so a few apps don't run in the background, and I deleted many of the bloat/AT&T apps that I don't use.

So when I opened up my battery usage I noticed that Android OS was at 70% usage (69% now in screenshots). I check my battery usage several times throughout the day and Android OS was not consuming 70%. It seemed to spike to 70% consumption, which points to an error in battery usage charts.
The steeper drops at the beginning and toward the end can be attributed to the poor reception areas I was in and my heavier screen on time during those periods. The flat portion in the middle is when I went to bed and left my phone for about 8 hours. Notice there are no huge wake locks during my time off battery.
This is my current screen on time....
I'm guessing this is an error with the battery usage calculator but I'm not completely sure. How to know if this is an error with the battery usage or is Android OS really consuming 70% and how I should fix it?

I'm having a serious battery drain problem with my Neo. It seems to drain very quickly within 8 hours sometimes less, and when it gets to about 30% it will suddenly say "no sim card", the battery icon flashes red and then all power goes completely and have to recharge. When the 'phone is switched on and idle, it gets VERY warm, never mind about being used.

So after I got the new update, the battery continues to drain even after I plug it in to charge. It's VERY annoying. This never once happened before the update.

This phone is nice but the battery life has been miserable I've had it for a month and yesterday I was at 4% battery with only 2 hours of screen time and the battery screen says the screen is always using 33% of the battery. I have turned brightness to low and set timeout to 15 seconds and its still the same thing. I also wiped the cache partition and charged the battery overy night with the phone off and nothing changed.

I've recently bought Xperia z2 but right now i'm having severe battery drain issue. At the first day it showed me average time of one & half day but right now its draining much faster & i'm only getting battery life of 13-14 hrs, only using wifi & music app. stamina mode is active but still no progress. How to reduce battery drain? i've seen some post in this blog where people said they are getting battery life of around 4 days.

I generally use chrome for browsing and battery drain is inconsistent. Usually it is very fast and i have to charge twice in a day, but occasionally it's great and lasts much longer. I cannot figure out what's different on the days it lasts longer.

I have a problem with my Xperia Ray after the ICS update, now the phone drains a huge amount of battery when its just in standby mode. create a downgrade tool that lets you downgrade to GB again.

Below is a screen shot from my Maxx. I don't know if the screen consumption is ordinary, but I am surprised that the screen alone is causing substantially more than half of the battery drain. I have the brightness set on auto, and I turn the screen off every time after I finish using the phone. Is this consumption normal?

The battery of my xperia mini pro got depleted during an update attempt, and since then it won't turn on, charge, nor be recognized by my computer through the USB cable connection. Hence the PC companion won't recognize it as well. It doesn't vibrate or turn any lights on, just gets a little bit hotter when connected for a long period of time.

I've updated my Neo to ICS 4.04 recently and since then apart from LED notiffications not working the stock Email app (not gmail) sync is not working. It was working earlier in GB. I configured my gmail using the email app and set the refresh interval to 1 hour but it never syncs or refreshes. It worked perfectly in GB. SONY fix this issue as I'm missing some important mails.
2. The media server is draining a lot of battery without me listening to any music. I really don't know why that's happening. I did repair my phone after ICS update but still this issue. I don't listen to songs on my phone as I have a music player but media server consumption is around 10 % and that pretty high.

I'm thinking of unlocking the bootloader of Neo V to flash JB but I'm not sure and I have some questions.
1.Will a new rom help on perfomance battery and ram mangement?
2.Will a JB rom drain too much battery in a small amount of time?
3.Can I go back to the original GB rom?
4.Will the GB Camera app play on a new Rom and can I find it as an .apk?
5.Is there a stable JB 4.1 Rom or even better 4.2 for Neo V?
6.Can I unroot my phone on the new rom?

Over the last 24 hours i've notice my Xperia Z2's battery is draining very quickly, even when asleep. Even when it is plugged in charging, i keep getting messages saying the phone is unable to charge as it is using too much power. And previously i could charge the phone overnight fully, now it doesn't get close to 40%
In addition to this I've noticed it is kicking out a lot of heat at the top of the phone, and also i can no longer connect to the internet via wifi.
Everything else seems ok, and i have managed to back up my data to an sd card. I haven't added any new apps recently.
I've had the phone for less than a year and as far as i know it hasn't had any heavy drops or anything.

I'm with a 5.0.2 D6603. The issue I have is that the following Kernel wakelocks does not allow the phone to deep sleep.
msm_serial_hs_dma
BTLowPower
I've just performed a sw repair via pc companion, and several factory reset. I'm running the Z3 with no apps.
It happens both with an LG G Watch R (5.0.2) and a regular BT Plantronics (voice only) headset. Using the same BT devices with a Nexus 4, Nexus 10 and an LG G2 does not have the same effect. As soon as there is no usage the phone goes to sleep immediately.
If we take the second device, I do expect a Kernel wakelock while speaking or streaming music. The phone is active any way while performing this task. What is strange is that even if there is no activity the wakelocks avoid deep sleep.
What is strange is that if I move away from the headset (and the BT icon goes the "non connected" status), the wakelocks are always there. The effect is that my phone (both on 4.4.4 and 5.0.2) almost never ever sleeps, and sometimes get warm. It is evident that the battery life affected a lot. If I switch BT off, everything goes back to normal.
I did a further test, in the below sequence:
- BT ON + connected to a Plantronics headset => wakelock + device always on
- BT ON + disconnected to a Plantronics headset => wakelock + device always on
- BT OFF + disconnected to a Plantronics headset => no wakelock + device sleep
- BT ON + disconnected to a Plantronics headset => wakelock + device always on
