Xperia Z2 :: Sudden Battery Drain / Not Charging / Lost WiFi
Jul 29, 2015
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%
Â
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.
Â
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.
Â
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.

went from 100% this morning (charged overnight) to 40% 2 hours later with no usage other than sending 2 emails! No new apps running - nothing. I normally get at least a day and a half of usage.

Around like noon today my phone started chewing through my battery. It is truly unbelievable. Goes down a percentage point every few minutes. I restarted, closed out of apps, made sure all the battery sucking stuff was off.

I have the Lumia 820 with the Navigon navigation app installed. I went on a trip this past weekend and noticed a strange battery drain while driving to my destination. The drive was a little over 2 hours and I was charging the phone the whole time. I figured I would test it on the drive home. I charged the phone completely before starting the drive home. I was camping so I had to use the lighter jack in the car which is always on and charged the phone from less then 10% to 100% overnight. Again the drive was a little over 2 hours, had the Navigon app open and running the whole time and the phone was plugged into the lighter and the charging icon was registering a charge the whole time. The only other thing running was cellular data. NFC, Bluetooth, Wifi, Nokia Drive, all off. When I arrived home the phone was at 45% and was very hot.
I upgraded from the Samsung Focus and using the Navigon app in the same car never ever had less power when I I ended a trip to when I started a trip. I use the Navigon app all time so this is a real issue. I am also going to post this on the Navigon website.

battery draining while using GPS in the car? Yesterday I drove for two hours and went from 99% to about 48%, all while charging (no other apps running, auto-brightness, no bluetooth, etc.) The charger isn't the fault as I tested it with my wife's M8 (using same apps, etc.). The M8 reached 100% and stayed there. I've since purchased a 2.0 quick charger (which I've yet to use) but why the performance would be drastically worse on the M9. I ran a check disk on my SD card (Sandisk Ultra 64GB) and so errors were found. Outside of the car/GPS use, battery seems close to the M8 but, if anything, a little worse. I can live with that but cannot have my phone drained after a long drive in the car.

I've had the 3D for a few weeks now and overall think it's a great smartphone. I was expecting poor battery life but on two occasions it went from fully charged to brick dead overnight (6-7 hours). Most apps, bluetooth and GPS off. I haven't experienced such quick drain during the day when I'm using it. I have also noticed an excessive amount of heat while charging.

I was transfering files from the computer (MAC) and all of a sudden connection was lost. I was asked to restart the phone, so I restarted the phone, but it never opened. Now it's just dead, screen is black and the charging led (orange) is lit. Nothing happens. I held start-up button for 4 minutes, but nothing..

My iPhone 4s is my first iPhone, and I really enjoy using it, but I was severely dissapointed when I discovered this major battery-usage flaw. Using wifi drains the battery incredibly fast. If wifi is left on, it will drain the battery (just on standby) within a day. Once I switched off wifi, it lasted over 5 days on standby. Do they know why wifi drains the battery like this, even when just on standby? Can this be corrected? I figured they would have fixed something like this by now if they could; I'm concerned it is a hardware problem that can't be addressed.

Strange that there aren't much complaints about that, but after I got the even buggier 5.0.1 update, the WiFi's battery drain is unstoppable. My usage and settings are exactly how I left them before the update several days ago. WiFi uses about 60% while the phone sleeping. No abnormal wakelocks details detected

I've had my Atrix HD for a couple of months, and am generally quite happy with it. The biggest problem I'm having with it is how fast the battery drains when I'm not connected to WIFI. Most of the time I am on WIFI either at work or home. When on WIFI the battery lasts 12 hours or more easily with reasonable use. However, if I'm on the road or out somewhere not connected to WIFI, the battery will drain very quick. For example, yesterday I unplugged my phone at about noon and was at home all day. At 9pm it still had 60% charge. I then left home for the evening, and by midnight the phone was dead. I didn't even make any calls, only checked an address on Google Maps. I did notice the phone was pretty warm during that time.
I've tried turning off WIFI and Bluetooth when I'm out, it doesn't help. It doesn't seem to matter if the phone is on an LTE network or not, as far as I can tell. I had an Atrix 4G previous to this, and never noticed a difference in battery consumption whether I was connected to WIFI or 4G, it seemed pretty consistant.

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 know there are multiple threads out there discussing this and I looked at most of them but this is different. My 9700 has gotten great battery life since day one, but this weekend I went out to the desert and didn't use my phone much because I only had EDGE but it was dropping in and out constantly, I had a full charge on Thursday morning and when I got home Saturday afternoon I had 20% which is pretty damn good I'm not complaining about that. When I got home I charged it fully and then on the middle of the day on Sunday my batter was almost dead. Same thing Monday and same thing today. I fully charged it yesterday afternoon and this morning it was at 25% and I hardly used my phone yesterday. SOMETHING has happened to my battery life, I'm running 5.0.0593 which hasn't ever gotten me fantastic battery life but its been okay but now its just shot.
I haven't changed anything on my BB for this to happen so I'm posting here for ideas of what could be causing this, I've looked at programs running closed everything I can and do not have WIFI or bluetooth on and Have constant good 3G reception.

iPhone won't reload. Lost battery power and the phone would not turn on after charging. Tried the restore and get to "Restoring phone" but the status bar on the phone never fills in. Restarted my Mac, did not have a problem connecting with Apple.

So when I opened up my battery usage I noticed that Android OS was at 70% usage (69% now in screenshots). Â I check my battery usage several times throughout the day and Android OS was not consuming 70%. Â 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. Â The flat portion in the middle is when I went to bed and left my phone for about 8 hours. Â 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.

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.

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.
