Hm... it is either something unusual with my phone or maybe my phone usage is rather unusual -- although when using my sony xperia arc heavily, with gps, wifi or data enabled and screen turned on almost all the time, I usually have to charge the phone by the end of day, when traveling, with the gps, wifi, data and 3g disabled, screen dimmed and HW key backlight disabled, with couple calls per day + couple text messages sent and received, the battery lasts for up to 5 days. Well, the phone is running standard firmware, currently 4.0.3 (ICS), it's rooted, many unnecessary apps have been removed, others are disabled when not required, but, honestly, with the standard 2.3 (GB) firmware it was also running very well, and I didn't have to charge it every day. So, the comments questioning 30h+ battery life reported by many people are rather strange for me.

We have smartphones, but we have to be smart enough to use them in an appropriate way -- people are complaining about a battery life while having a 3g, WiFi and BT enabled all the time and screens burning their eyes out, with the brightness set to 100%... -- I have a screen set to automatic + ScreenFilter set to 50%, sleep set to 30 sec., disabled HW key backlight at all, disabled 3g because I usually don't need it, manual data, as well as disabled all automatic synchronization mechanisms and updates, etc. -- I'm syncing manually, sometimes leaving this enabled, while charging and/or online via WiFi. The screen brightness is one of the most important factors -- it literally eats the battery /To be fair, I have to say, that xperia arc screens are very bright, so, 50% is still very bright (and 100% burns the eyes out immediately)/

And last thing: I don't know other brands, but the latest xperia devices are shipped with a greenheart chargers -- they charge the battery almost instantly, so if the phone battery is close to 1%, 10 minutes of charging will give you will 1h of a talk time.

My Samsung Galaxy S 2 (T989 version from T-mobile) - barely lasts a whole day. But recently after trying some new roms, currently running Infamous 4.03 ICS, V2.85 (not sure if it's the cause of it), it's been draining noticeably quicker. Not sure if it's my battery getting older (4 months old), or I've exposed it to too much sun/heat from being out doors in the Las Vegas summer heat too much? :silly:

I just ordered 2 Anker batteries from ebay (supposedly a decent brand compared to some of those unknown no brand batteries on ebay). Will see if any improvements before I change ROMs again.

Dose portable external battery charger will help to extend the battery life?
[General Accessories] FloFloIsMyName:
A smartphone is like mini-computers, so battery life is not his forte...

But you can make a huge difference if you make somes adjustments !

I've a Samsung Galaxy Gio and with stock rom my battery life was not very good (it's an understatement lol :silly: )

Now, after two month of "learning my device and android", it last at least 3x time longer :

- Custom rom based on CM7.2 : DebianDroid LENNY 5.0

- Kernel by Phiexz

- Adrenalie Engine

- A choice of good apps which i've test myself to find the best ratio performance/easy of usage/personnalisation/battery

- Settings "battery friendly" :

--> screen luminosity 20% most of the time, CPU 122 - 826 mhz with Smartass v2, JIT, 16bits transparency etc.

--> Plane mode during night time (I sleep 8 hours and my phone doesn't loose one percent)

--> 2G/3G et Wifi only when i use them

--> No accounts automatic synchro

--> No Battery savior or task killer apps, if you understand the way your phone works, no need of them !

So, the best way to give your smartphone extra battery time is to try a lot of configs and find the right one for

your

usage...

My GIO with all above lasts up to 4 days (but it's because I mostly text / phone and occasionnaly gaming / web based apps) so It's possibly to enhance battery time with the right settings ! Don't lose faith :D

[General Accessories] MissionImprobable:
One thing is clear: getting rid of bloatware is the biggest aid in extending battery life. Even with the issues that have come up with devs having to port ICS to my device all on their own I'm still seeing anywhere up to 70% of battery remaining on low usage days and around 30% during heavy use. 1850 Extended Motorola battery on my D2.

I'm a bit disappointed by the battery of my Padfone so far, but I think it's mostly because of the battery drain bug in 4.0.3.

[General Accessories] DruidXL:
less than a day

My Sensation stock battery lasts about 24 hours with only phone calls and texting. Any gaming, WIFI will reduce that to about 1/2 a day. Also I found that roaming cost extra power as well.
[General Accessories] SacTappingUni:
I have a rooted, over-clocked Nook Color. I can get extremely awesome battery life on it. I don't need to be cautious about battery usage while going through my day. I can do whatever the hell I want on my nook and I'll still end up with about 30% or more battery life left.

Also, when in sleep mode, my NC averages 1% battery loss per day. I really love its capabilities and satisfactory battery life.

[General Accessories] Syrusoo:
The biggest difference for me on my Galaxy s2 was wifi. The place I work at I'm able to keep a connection to Wifi for an entire 12 hour shift and in the morning if i never used my phone it was around 50-75% of a charge. Keeping in mind I am currently rooted and have different kernels installed that under clock my ROM. But the biggest consumer in my phone is usually the screen and then the 4g.

I'm getting about a day on my S3. Well, actually - I should say I think I am. Really depends on which build of the ROM I'm using. And if my phone is being nice today. Its still new so I suspect it'll normalize over the next few weeks.
[General Accessories] slanidracula:
I am a poweruser on my S3. I am streaming music, reading forums, flashing roms, texting, and tweaking a ton (my display is on a lot). I have to charge after 8-10 hours. If I am otherwise engaged, I can easily be at 50% after 12-16 hours. But, if I am travelling and switching between 4g, 3g, and 1x (gag), I'm in trouble. Not bad for a 5" screen.

Hi there folks! First of all let me apologize in advance if this isn't the right section but I can't think of other.

I'm trying to do a video showing some of the features of my app, the JotPad. But I'm having a lot of trouble, I've lost count to how many "takes" I've done and I still can't get it right, I'm always forgetting something or mumbling in the middle of the video, or laughing... seems quite obvious to me that a career on television is something I shouldn't aspire to. :D

My Portuguese accent doesn't help either, but then again it's not that imperceptible. :P

My question is, how did you guys made your own videos? I can't use a emulator capture cause I need to demonstrate the multi-touch aspect of the app. Any advices?
[Android Q&A, Help & Troubleshooting] rwgast:
So I've been busting my brain thinking about this. If you have installed a chroot environment to run Linux on your phone why can't you just startx? Why do you have to view the desktop via vnc? Its my understanding that Linux is just using the android kernel and the display drivers for the phone are in the kernel so why is it that no one can get x running and visible? I'm really untreated in what it would take to achieve this.
[Android Q&A, Help & Troubleshooting] Gusar321:
Display drivers have many components. It's not all in the kernel, not by a long shot. For X you also need a DDX (device-dependent X) driver. This is what we're lacking. And possibly other components too.
[HTC Rezound] skyisthelimit83:
ok, so i unlocked and rooted my rezound, everything was working 100%, then i start flashing diferent roms and it was conecting to wifi with no problems, however when i flashed ( or tried to flash ) a new kernel ( dont remember which one ) wifi stoped working for me, it scans but doesnt pick up any network. i went back to stock kernel and nothing, re-locked device and installed verizon factory Ruu for the rezound and Wifi still doesnt work. Im going crazy here please help, maybe im flashing the kernel wrong but re-locking and restoring to factory Ruu should have fixed it :confused:
[HTC Rezound] sdsmithinc:
I was also having the same issue and tried reinstalling kernals and nandroids. I was loading the kernal through Amon Ra interface directly and no matter what I did I still had issues. Sooo, I revised my recovery process and found that dummy me can't read instruction correctly. The issue was resolved after I did a factory reset on the rom (Ineffablis v1.0) then I followed the instructions for installing the kernal (I'm using the SmartassV2 kernal from dsb9938; flash from SD, then flashmethis file and finally through HBOOT, it's a process ok?), rebooted and I was able to get WiFi working again. I've had this issue whenever one of the additions I was trying did strange things to my phone and have sucessfully restored WiFi (about 10 times for this occurance). I've also had to do a hard reset (pulled the battery) and follow the process to get back to functioning. Hope this helps.
[HTC Rezound] skyisthelimit83:
i locked the phone again, and ran the rezound stock Ruu and did factory reset, still not picking up any networks. the wifi doesnt give and error it scans and everything, but for some reason it just doesnt pickup any networks :mad:
[HTC Rezound] zetsumeikuro:
If you read the complete directions when flashing a rom... They state you will need to flash the wifi module after a fresh install. So just flash the kernel over again and you will have wifi working.
[HTC Rezound] skyisthelimit83:
Thanks a lot, finally got it working

[Sony Ericsson XPERIA X10 Mini] santaranger:
Hi everyone,

I've been running MiniCM 2.1.5 (nAa -06)for a few months now and it runs pretty fine and it's very nice to have Gingerbread and so on.

But I'm very disappointed with battery life and I don't see why it is so bad.

I understand the MiniCM should have similar if not better battery life than stock (2.1) firmware but I don't see how this can be achieved.

I always used to have 2G/3G enabled, and with stock ROM my battery would last up to 5 days with minimal usage. With MiniCM I don't get over 2 days. With normal (low) usage, my battery now lasts about 30 hours.

When the battery is empty after a minimal usage cycle, I have something like 49% cell standby, 45% phone idle and a few % display, which basically means I'm not doing anything with the phone and there's no app running in the background etc.

Switching to 2G only (and other famous battery saving tips) will give me some extra hours, but still nowhere near stock battery life (with 3G/2G all the time).

I have no tasks running that should drain battery,

I have also wiped battery stats (using the BatteryCalibration app) with no noticable effect. My voltages are displayed between 4.15(100%) and 3.65(0%) . Shouldn't it drain down to 3.2?

What are your mini battery lives?

What are your voltages at 100% / 0% battery?

How to make MiniCM last as long as stock ROM?
[Sony Ericsson XPERIA X10 Mini] jimcantfixit:
I never get any more than 14 hours on Flame.GDX, also on MiniCM7pro I got roughly 12 hours.

I dont think theres alot you can do. JuiceDefender an apps like it may be able to help you find an hour or two longer
[Sony Ericsson XPERIA X10 Mini] santaranger:
I have returned to stock 2.1 after a lot of experimenting.

I have tried:

- MiniCM7 2.1.5-7 with nAa

- GingerDX with nAa

- MiniCM6 1.0.2 with stock kernel

I have found that all of them use a lot of battery, though i can not see why.

They will all result in ~<50h standby, while stock 2.1 can reach ~100h.

I wonder if this is some SE secret, or if one can achieve this with custom rom, too.

Did you have CWM installed before? If yes get SuperoneClick and a custom .zip rom (e.g. redy's). And put .zip Rom to ur sd card.

1. Extract Superoneclick to C:

2. rename the folder to SO

3. then open Command Prompt by typing cmd into search/run or push windows + r and type it there

4. when command prompt is open type "cd so" without " "

5. type "cd adb"

6. type "adb reboot recovery"

Hello XDA-Developers Forum :D

Since a week or two i got this annoying problem. When i call someone (or answer an incoming call), I can hear the other side clearly but they can't hear me. When i call my mum's phone to test it, and when i put the 'speaker' of hers on, and i shout at my own telephone, i can just hear a little whisper on my mum's phone speaker. Flashing an other ROM didn't seem to work. Also in Voodo Control, setting all settings to default didnt work..

Maybe someone else has experienced this too, and can help me with this? :)

I know flashing a stock ROM would maybe fix the problem but i dont know how that works.. There are like 10 stock ROMs to choose from; What one to pick?

EDIT: I've flashed to a stock ROM. Nothing changed. Problem not solved :l
