[Q] Question before buying a new desire

I have decided to buy a new Desire phone.I read on many forums that battery backup on Desire is very very bad.I need this phone for gaming atleast 1 hour a day.Whether there are any tricks to increase the battery or the battery backup has no problem?

Desire's battery consumption isn't so good, but to play 1 hour a day, is ok even with stock roms.

What is the standby time if i give a full charge?

If you're not using it could be around 5 days.
With moderate use 2 days.
Heavy usage 24h.
Sent with smoke signals.

I think with heavy usage phone working 24 hours is not too bad.Tell me what will be the battery life with the following usage:
1.5 hours gaming,1 hour browsing,1 hour music,45 minutes running apps and always running a live wallpaper.

Probably around 24-36 hours.

Is a bit impossibile to know how your battery will "live" with this usage, because not all apps have the same battery drain... so, we can only imagine...
Live wallpapers use a lot of battery, wi-fi drain is more than 2g/3g network drain... i think that using MIUI or AOSP rom, with this usage, you can stay 24h without recharge... with stock roms 12-16 hours maximum...
Sorry if my english isn't perfect

Agree, around 36 hours.

And also,Can it run latest games without any lag?I need a phone with this budget.I selected Motorola Defy and this one.Which is better?

both are good devices...

But select anyone from those two.

From these two Desire, but in this price range there is also Samsung Galaxy S which is slightly better from hardware point of view but i would get Desire anyways.

Galaxy S's price is higher in our country.120$ more than these phones.I need a good phone in 340$-360$ price range.And what about HTC Google Nexus One and Sony Ericsson Xperia mini pro?

[Q] Why ICS custom roms drain so much battery?

I loved all ICS custom roms I tested (all of them, I think)... but they are really poor in one aspect: the battery life. It's awful... 50% in 3 hours or less with average use. Is there any solution for that? Which one do you guys use? Thanks

I'm using IceLite by zdzihu on my LT15 and my battery performance is great.
I think that some baseband's are better than others for battery, also, I've added this to my build.prop file:
ro.semc.enable.fast_dormancy=false

There's a bug in ICS beta that drains batttery with wifi off, though it doesn't seem to be present in Z's icelite.

It's in all of them, but it's intermittent.
Some days things would be great, then all of a sudden it would start draining the battery like crazy.
Some people never suffer it, but that does not mean the bug is not there, just that they aren't doing whatever is needed to trigger it.

I'm using Z's ICElite and i have the best battery life i ever had. it's even better than on gb arconium. I'm loosing about 1% per hour on idle. Ok the first time i flashed icelite my whole battery was dead in 7 hours and android os drains 80%(!!!) After two times of complete charging my phone android os drains only 18% and I think this will get even better after charging a few more times

So it seems that Icelite is the the best one for some time... I don't really like that rom's style, but i'll give it a try. I believe that when the official ICS is released, they'll fix this, and also will fix the weak wi-fi bug

Same here. I'm using IceLite on my LT15 and the battery performance was great at first, but drains an average 5% per hour on flightmode. (I use flightmode at night, because I need the alarm clock)

ICS Beta ROM in Xperia ARC S
I have installed the ICS Beta ROM in Xperia ARC S.
Why does empty the battery so fast? background process limit cannot be set, it remains at all times the standard limit.

stop nagging about it because it is beta for a test,not for daily rom,wait for a stable release by se,maybe all the issues gone
from the ARC

The only battery drain is linked to the wifi module.
The only solution I found is not using wifi. If I have to use wifi, I reboot the phone after I disable it.
There's no wifi driver in official beta. This driver is not even a beta one and has not been validated by Sony.
There is no battery drain in ICS 4.0.3 either (unlike some says).
Currently, my battery last between 4 and 5 days without data activated (just a few calls and sms). It lasts 2.5 days with moderate data usage (an average of 15 hours with data and sync activated).

Stock ROM has better battery life than AOSP and other ROMs

I've been migrating from many ROMs and I noticed that stock Sony ROM has a significantly better battery. Even though stock Sony has a lot of bloatware it performs better but AOSP ROMs are a lot smoother. I heavily use my phone with the screen on more than three hours and WiFi on.Has anyone other than me noticed that? Or is it just me.

yup me too, all jb 4.2.2 ROMS including CM builds and AOSP seem to drain a lot faster even on idle conditions. But i found paranoid android 2.57 jb 4.1.2 far better as far as battery is concerned and maybe better than stock and at the same time fluid and smooth.

I have xperia ion LT28at (at&t unlocked). I made the phone rooted and deleted some bloatwares with Link2SD software. There are many bloatwares like At&t related ones. Today I am trying the phone with full battery .
see the pic.

This is the minimal use of my phone after deleting bloatwares in stock rom. It is around 13,5 hours. Brightness was %15~20.
Here is the picture.
So,
How can I extend the battery life?

If you press "screen" in that battery stats menu you've just shown us, you can see the time that screen was on. That was what we'd like to see to determine if you battery life is abnormal compared to others. What you're showing doesn't tell us a lot. 13 hours is not much, but everyone has a different idea of what "not using the phone much" is.
What would your guess be for screen time, 2 hours, 3 hours?
Anyway, 13 hours is not much, your phone should be able to do much better if you didn't play any games. It really depends in Android what apps you have installed, because some bad apps drain battery in the background.

Give couple of more weeks to the phone. Charge more. Usually all the Xperia gives better result after few full charge cycles. And battery life varies actually.
Read the Battery life Thread available in General Section. You should find several tweaks and tips from the other users.

I have the same problem, on stock rom i had something like 0,5% battery drain per hour, on AOSP/ Jelly Bean roms i have 2~4% per hour...

I had 50% of battery at the end of the day. I just used my phone for SMS and calls, no wifi no mobile data 30% screen brightness and on 2G .

[Q] SGW I8150 drain battery very very fast after i flashed it with CM-10.1 alpha6

i just flashed my samsung galaxy wonder to have CM-10.1 alpha6 a few days ago. and i realised that it drain battery very fast.. just simply fully charge it to 100% and left there with wifi,bluetooth and all applications off, yet the battery drained in half day..
if open 3G, the battery drain 30% in 20 minutes.
can sumeone tell me what's the problem and how can i solve it? thx a lots

Why don't you try to flash another kernel..
I personally recommend kernel by hurtsky, or by castagnaIT.
that's only my opinion..
you're welcome to try..

Well..
It's just the same way like how you flashed the cm10.1 rom..
Try to head to this page:
http://forum.xda-developers.com/showthread.php?t=2218087
There's also an instruction on a proper way to flash it..
And don't forget to thanks him if you like his kernel

CM10.1 aka Android 4.2.2 uses higher voltage compared to CM10 and CM9(especially CM9).
So its understandable. But in CM10.1, SGW can use 1.0Ghz and still fluently do a lot of things.
Try underclocking and undervolting.

agree..alpha 6 still not in revert kernel..maybe your lcd is the main cause drain your battery..

I have CM 10.2 everythings is ok..battery consumption is depends from life time of your battery then the number of apps and services activated...

Change to new battery
hmmm.... maybe it's because of your battery.. from my experience , you should buy new battery if the battery is used more than 1 year... i had experinced before when my battery drain faster, after i bought new battery.. the problem solved...

Guys. Stop telling him it´s the battery. If it were the battery the draining would be already that fast before flashing CM10.1, but not just after.
A bloated and aged battery can of course be the reason, but this doesn´t have to be always the case. My stock Samsung battery is already 2 years old but working like new. However I have to admit that I don´t use it that often. Having here 3 batteries I´m changing them regulary every few months.
This draining will be more related to the LCD version in his phone, which he should read about and check before flashing a CM10.1 based rom. Additionally the recent Google updates can cause even more battery drain than the LCD Rev.3 issue alone, which has to be taken also into account.

Note 2 giving very poor battery performance. Drains very fast

Hello everyone!
I purchased a new note 2 1 month back. But i have noticed that my note 2 doesnt give me THAT GREAT BATTERY LIFE which was advertised.
I usually get about 12 hours of battery backup with just 3 to 4 hours of screen time and 30- 60 minutes of voice calling on 3g network.
I am on rooted stock room (4.3 jelly bean)
Please help me folks!!!

An easy way to get better battery duration is to use the Wakelock Detector application. When you see that an app is called many times (even if you haven't opened it), you can disable it via app manager.

Charge your battery completely and calibrate it again.
by pressing *#0228# and press quick start and the moment you push this your screen will go off and come backup in few Seconds so patiently wait for it to come back and then observer how is the battery backup.
Optional only if Rooted.
If you are rooted use Greenify app.
check with Better Battery Stats to see who is the culprit who is draining.

Use greenify

Me too just purchased a second-hand note2, realized that alhough it comes with 3100mah battery..it uses lotsbof juice for the large screen, obviously!
Here's what I did
Root the phone and install greenify.
From root explorer delete the apps that can be foundbin playstore..such as gmail, maps, youtube etc.
This way you can greenify the apps mentioned...saves a lot of juice (battery)
Hope this helps.

I have tried every solution mentioned above but still my battery is draining way to fast than before.
How do guys manage to get upto 2 days of battery backup from that monster. Mine doesn't even last for a day
I have flashed phoenix ROM v.17. It didn't help either..

Try to kill camera app after taking a photo. This one was draining my battery so fast.

Have you gone into wifi settings advanced and unticked scanning always available. That is the biggest battery killer for 4.3

I can't even watch a complete movie w/o getting the battery drained.

I am a Chinese.My English is very poor.I hope I can give you some help.The following is my search on the Internet to China.You can copy the following text use Google Translate to translate it into English, I hope you can read this, thank you
一、屏幕显示
降低屏幕的亮度，可以有效的节省电能，尤其是摩托罗拉产的Android手机目前为止均为TFT屏幕，同时自动锁屏幕的时间设置的短一些也会带来一些电量的节省。
二、减少后台运行的程序
很多Android软件不管有用没用都喜欢在后台运行，这样无疑增加了CPU的任务切换时间，当然由于Android系统设计原因，软件无法自动退出，可以使用第三方的小工具来解决，比如说手机优化大师的内存整理功能。
三、关闭动态壁纸，减少桌面小插件
Android系统在桌面上有很强大的功能，动态壁纸和appWidget小插件都是电量消耗大户，如果使用一个静态的图片作为Android壁纸会省不少电量，同时很多桌面小插件都是后台长期运行，比如天气、资讯、包含秒针的时钟或系统信息实时显示的小插件都比较费电，根据需要能减少一些更好。
四、WiFi、蓝牙、GPS、重力感应
对于智能手机来说，平时不用WiFi时一定不要忘记关闭它，同时在锁屏幕时尽量使用WiFi休眠功能，同时蓝牙也要禁用掉，GPS定位由于需要实时接收卫星信号十分费电，如果不在导航时一定别忘了关闭，对于重力感应来说由于内部的硬件需要时刻采集数据，同时屏幕的横竖切换都是很费电的操作。
五、尽量不在信号差的地方通话或上网
对于手机来说，信号差的地方通话或上网，手机底层的基带驱动会自动的加大收发功率，除了更耗电外辐射也会比平时大很多，所以信号质量不好一定不要上网或打电话，发短信这些操作。
六、尽量少用包含广告的软件
对于Android手机上很多软件都是免费的，但仍然有不少的软件内置了广告，由于处理广告的图片变换以及不停的下载广告图片除了更耗费电量外还会浪费GRPS流量，所以尽量少用包含广告的软件，部分广告插件还会收集用户隐私等问题。可以使用APK安装器3.0系列在安装APK之前就可以发现广告。
七、 尽量购买大RAM的机型
对于Android手机来说，更大的RAM可以有效的减少电池消耗，经过Android123开发站点评估，Android软件使用的Java语言开发，在内存吃紧的情况下系统会频繁的使用Java虚拟机的GC机制，增加I/O交换和CPU运算，所以2011年买的安卓手机，至少512MB RAM，当然很多768MB或1GB的运行内存都是十分推荐的。
八、晚上睡觉时使用飞行模式
如果你晚上睡觉时不需要开手机，可以不用关机，直接进入飞行模式就可以关闭GSM移**络通讯，这样的好处除了省电外，可以降低手机的辐射，Android手机的开机需要加载初始化大量的文件十分耗电，反复开关机也会大幅减少手机待机时间，快速进入飞行模式可以使用手机优化大师的快捷设置功能。
九、降低来电铃声音量
如果你听觉比较灵敏，可以适当的降低来电铃声的音量，同样通话音量也可以降低来达到省电的目的，但是不要设置的太小，以免耽误大事。快速调整各种音量的方法可以使用mTweak的快速设置，音量调整 功能。
十、定期更新软件
目前很多软件的设计并不是很科学，在设计逻辑上严重影响了安卓手机的续航能力，这点可以通过更新到新版本来解决一些开发者初期设计应用的不足。
