[Q] Huge Battery Drain

Hi,
since a week or so my u8800 suffers from a huge battery drain.
Today i just got 10hours out of it and almost did nothing. (4min. phone call/ 10messages/ max. 10min surfing)
The last 10% of battery was gone in 30 seconds.
It all started last week when my phone was on stock 2.2. Then i updated to the latest stock 2.3.5, but still the same problem.
Model number : u8800
Android version : 2.3.5
base band version : 404020
Kernel version : 2.6.35.7-perf [email protected]#1
Build number : U8800V100R001C00B528G001
I also wanted to calibrate the battery, but i can't root the phone. Tried every program out there
Anyone got the same problem or has a solution ?

Hello Kawadude,
I use superoneklick and it works fine to root the device. Hier ist the how to, what you must do before use superonklick:
- Dial * # * # 2846579 # * # *
- Go to projectmenu, background settings, log settings, log switch and set Log on
- Reboot phone
- Set USB debugging on
- Run superonklick http://depositfiles.com/files/n0dcxce3t or http://shortfuse.org/
Hope it helps

Already tried that without a result.
I also tried DooMLoRD v4, Unlock Root and One-click Root.
Since i installed the official 2.3.5 i can't root my device annymore. On stock 2.2 this wasn't a problem.

Hello, do you keep wi fi enabled at all times? i noticed my battery drains increased greatly when i leave my wifi on 24/7

No, wifi is only enabled when I'm at home.
A couple of weeks ago the battery life was just fine. (With the same usage)

Close any application in your pc that might try to connect with an android device (like huawei's or Asus PC Sync, etc). Those applications use the adb driver and block superoneclick. Check if windows recognize your device and install it properly. Hum... That's all I can think of... ;-)

Try this. I did hear that this last release from huawei (B528) couldn't be/was really hard to get rooted. I haven't tried this, just found it. Credit to @Igory0k.

Didn't work for me.
The phone rebooted and freezed at the huawei logo.
The only thing i didn't find is step 6: "6.log setting-dump & log-on"

You have to do it, rooting apps need that option
And launcher apps etc. don't install them, your battery won't drain Uninstall unnecessary apps too

[Q] Rooting Official 2.3

I have this V100R001C00B528G001-version which is the newest and came out 2.3.2012. It works very nice, but cant root with superoneclick2.3.3(stuck in step#7, cant mount and stuff) or GingerBreak. Has anyone got rooted, help me how? thanks

You need to modify the boot.img firstly (modify the default.proc, change "ro.secure=1" to "ro.secure=0") and use fastboot tool to flash it to phone.

I screwed up I think

So this morning I was fiddling with my Galaxy S5 (SM-G900W8). I was trying out those secret dialing codes because I kept getting a MMI error.
So anyway I launch up *#4636#* and I select "TURN OFF RADIO" and "TURN ON SMS OVER IMS" as per this website guide http://www.technobezz.com/fix-connection-problem-invalid-mmi-code/
As soon as I did that, my network was shut off and I tried re enabling it but it still won't turn back on. I tried factory reset, firmware install through Kies, took it to Telus, who didn't know what was wrong with it. I tried re entering my APN settings, selecting any Network in settings tells me "Your SIM won't allow connections to this network" even the network I am on (Telus)
I tried changing CSC, I am currently downloading firmware to flash in Odin, hoping that works.
But can anyone give me suggestions? I feel like since I just switched a setting, I should be able to turn one back on.
EDIT: Flashing official firmware in Odin did not work.

First, no need to screw up with those things such as changing APN or CSC...
I have turned off radio and then turned it on without problem.
So you can try to turn it on again.
Can you show the screenshots of it?

It actually says "Turn off Radio" every time I reboot so it seems to turn on that setting anyway. Which does nothing.

1- Got a question: in the 2nd screenshot, why it showed a full list of bands (Automatic/EURO/USA/Japan...), while in the 4th screenshot, the list is empty? In my device the list is always empty (as in your 4th screenshot), I don't know why.
2- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#197328640# > 'Launch 0' > BASIC INFORMATION (capture screenshot #1) > Menu - Back > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).
3- If you don't have root, open the dialer > *#0011# (capture screenshot #1) > Menu - Back > Menu - Key Input > Q0 > wait... > DEBUG SCREEN > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).
And post these 3 screenshots for more investigation.

If Radio is turned on, I get no options to select.
If Radio is turned off, I get those options, none which work.
Screenshot 1 - http://i.imgur.com/OBQc4IQ.png
Screenshot 2 - http://i.imgur.com/G5K7VZk.png
My screen didn't have a MM REJECT CAUSE menu and my phone doesn't let me press back to get to previous menus, so I took a pic of SIM INFORMATION to see if that helps. http://i.imgur.com/zvpKfyh.png

The network has considered your phone as a illegal device and refused service either because an identity of the phone is not acceptable, or because the phone does not pass the authentication check. I dont know why. It should be a false positive report.

I Fixed it!
I kept messing around in ServiceMode and finally found the setting to get my network back. It was NV settings that I reset under PROTOCOL. Told me to reboot and voila my LTE was back. SMS and calling didn't work so I factory reset and now everything is working fine. I knew my SIM was fine and my EMEI was fine. I knew it was something I could change myself.
Thank you for the help man. I am now going to never install that Phone info app again unless I have other problems lol.

Where is the option to change the resolution?

I used to find it in the battery settings but I can't find it using the new firmware?

Hi
On firmware B029 Stetting - Advanced settings - Battery Manager > Enable ROG power saving
On firmware B332 Stetting - Battery Manager > But not working

So you are saying with the latest firmware, there is no way to lower the resolution from 1440p?

nope on stock B332 B350 Emui 5.0 have bug

Thanks!

Is there a third-party app (also for Root) to enable ROG and change screen resolution?

Android System - Excessive Battery consumption on MIUI 11.0.4

Hello all,
Maybe somebody can help me here.
I've recently updated my device into the MIUI 11.0.4.0 (QFJEUXM) rom . Official OTA update by Xiaomi,
I've noticed an increase in battery consumption ( mainly caused by android system app around 25%).
Somebody with similar issue ? is there a way to rollback safely into a previous version ? My previous version 11.0.3.0 was working just fine... I'm actually regretting having updated my phone.
Kudos!

Yes, many users have the same problem, including me.

Well, I feel my Mi9T has strange battery consumption through all the roms.
I'm now on custom rom with 11.0.4 vendor. Some times it uses more than 1%/h while deep dozing.
Screen on time is estimated to be around 8h, is this too short?

I'm getting sick of the android system drain. Does anyone know if xiaomi.eu rom any better? Is it worth flashing?

1. Unlock Developer Mode
Settings > About phone > tap (many times) on MIUI version until you've a message "You are developers!"
2. Turn off MIUI optimization
Settings > Additional settings > Developer options > Turn on Developer options (if it's not) > scroll down to the last page and Turn off MIUI optimization
it's work for me!
