Battery Drain since 4.2.2 Update - Xperia Tablet Z Q&A, Help & Troubleshooting

Is anyone else having battery draining issues with the new update ?
I have the 16gb WiFi only version. My battery is draining at ~1% a minute while browsing the web. My battery usage looks like a series of cliffs. For the chart here, 62% of my usage is screen usage. I've been keeping the screen on low brightness or on auto and I see no difference. I know the battery on this tablet was never the greatest, but during usage I don't think it died this fast prior to the update.

i think you should perform clean firmware install or find out what app drains juice from battery.

I actually did a factory restore yesterday and a full charge overnight. I'm going to spend some time observing the battery life today.
I never had many apps to begin with, but since the restore the only thing syncing regularly is GMAIL.

HI,
Were you able to find out what was causing this? I just purchased this tablet and the battery drain is terrible.
thanks,
dave

Root, deodex and remove bloatware is the answer to solve this!

[Q] Android System Draining Battery? *Pics Inside*

Hi All,
Ive had my sgs2 for about a week or so now and have been trying diff. custom roms almost every other day. Last night, after flashing the new villainrom 2.3 and its recommended modem, i think ive been getting the best battery life ive had so far....
HOWEVER, i find that my battery is draining for no reason still. I'm a long time android user, but also have an iphone 4. I dont expect my battery to be as great as the iphone 4's, but unnecessary drain is a little annoying. When I check my battery usage, this is what shows (look below), is this normal?
ive only used the display for about 2.5 hrs in 12 hrs, and thats the drain im getting.
Oh, and juice defender was JUST installed like 5 mins ago, so disregard that.

Why dont you try installing 2.3.4 KG1? I have it on and it seemed to have increased the battery life. Did you check any processes that are not shutting down?
Vr2.3 is based on kg3.
That looks ok, use titanium backup to freeze anything you don't use.
The most useful part of the battery info is the zoomed in graph with awake time etc.

Villainrom still has all the samsung bloatware in it. I have cognition and man my battery lasts long. No weird apps running in the background. Just JD Ultimate taking care of even more powersaving.
With regular texting and app usage (of course differs to any type of person) I get 32-36 hours of usage.

I'm currently using Darkside 3.2.0, faux latest kernel...

Thats exactly what I was thinking
Don't be concerned about wake locks if you get awesome battery life

First of all thanks for the replies.
I know its not the worse possible battery drain, however data was off last night as I wanted to c if my phone actually goes to sleep.
my other android phone drained maybe 2% overnight with data off, so 10% seems a lot to me...
I have an international ATRIX and m using the latest radio (100.00 something like this) and no matter which rom I flash (aura cm7, and now darkside) the phone just stays awake.
With light use it lasts a day, but ideally 2 days is what im looking for!
Thanks for reading guys

[Q] Is it a heavy battery drain?

Guys,
since i am not sure what does good battery backup means for our LG Optimus One, i have decided to ask you instead.
The flat line in picture is when the mobile was in standby mode almost 7 hours. Mobile was at 90% when i woke up mobile from standby mode. I have no problem for battery drain in that period.
My proble starts when i started using data on my mobile. I used data for almost 3.30 hrs and mobile reached at 5% battery level.

I wanted to ask you is that is it considered as bad battery backup? For me i sould have used the data 2-3 hours more. For my normal use also i cant get past 15 hrs in a day.
And why does Cell Standby and Phone Idle consume so much battery. I checked in Application/Running services "Settings, Juice defender, DSPManager, Google services and Android Keyboard" were running.
My battery health is Good.
I am on new bb. and on latest Nightly. With all other ROM even Oxygen gives me the same backup.
Help me to get better battery guys. How much battery backup you guys get.
Regards,
No that is completely normal....with data of course battery life goes down the drain. I get about 3-4 hours too so it's normal. Even on a Galaxy nexus it is the same thing.

Battery drain

So I recently updated to 402 firmware but was forced to downgrade back to 55 cause of severe battery drain and now back on 55 (after a clean install) the problem persists. I haven't installed anything yet and this is what my stats look like constantly

Note: Facebook is disabled... Lol and the name of the process that appears in the icon is: ANT HAL Service. I have no idea to check what's causing this since I'm not rooted. Anyone an idea?

Alright after countless restarts and force closing of potential apps that could be draining battery I managed so somehow make screen disappear completely from battery stats. I'm gonna reflash firmware cause this is kinda bull****. I've never had such issues before 4.4 and I'm getting the impression that there's quite a few issues with it so far..
Update: after reflashing a clean rom 2nd time in a row I still can't get screen to register in battery usage :S
Anyone got tips for me? I'm this close to going back to the store and getting a replacement.
Do a full wipe and see if issues are resolved.

Didn't work, got a new device today anyway. This one came with 402 and has no issues whatsoever.
Mine too, but not so munch. 5% per night. Heavy widget and home screen installed.

Phone idle drains so much battery at night

Hello I need help to reduce battery consumption when the phone is idle the device is an ASUS Zenfone Max M2 (ZB633KL) I bought the phone on March 30, 2019 it's first month in April was good and it only consumes 1% when idle the whole night sometimes it doesn't and then around May 17 until now the battery consumes more around 12% - 15% like last night it was 86% at 10:20 pm then I woke up it was 72% at 5:48 AM I don't think this idle battery consumption is pretty normal since batteries go bad after 2 years or so.
PS sorry for my bad grammar and I hope you could help me. Thanks
Do You use app like Smart View??I have this phone and never have this issue. You must have something installed and this drainbattery.

I don't have that app installed, only had facebook, messenger, and youtube. I might also ask if i could use my phone's 1 year warranty to replace the battery or the phone itself, the battery might be defective at all.
A little update on this issue a week ago after updating on Android 9.0 Pie the battery consumption became worst it consumes 15 - 20% maybe the update was buggier I found a lot of complaints from different users I will link a screenshot from last night and this morning.
last night
